no, you'll stop what you're doing and use !learn

hey quick question - how would I go about using loops like a for loop to iterate raycasts at varying angles. For example, this red line represents the ray cast. I would like to duplicate this every 15 degrees around the entire circle

[swift crag]

I'd use Quaternion.AngleAxis to calculate a rotation

Quaternion.AngleAxis(angle, vector3.forward) * Vector3.right;

This will spin the right vector by angle

[silver flicker]

Ok

[swift crag]

You can calculate angle based on your for loop's variable

[silver flicker]

I'll research that a bit

[carmine sierra]

so is using this really that much better than learning on the go?

[swift crag]

you currently have a very broken understanding of some really fundamental concepts

[carmine sierra]

true

ill come back then when i secure most of that down

[swift crag]

it is better to get a foundation from a single coherent source before you try to start learning things on the fly

[carmine sierra]

boxfriends a hater though damn

yh you right

[silver flicker]

I see, so for example, when i is equal to 4 then I can multiply i by 15 - I think I might have got it

[naive pawn]

"learning on the go" only works when you know enough already to extract more information from experience
you can't "learn on the go" from scratch

[carmine sierra]

more general question, since unity has alot of built in features which arent c# exclusive, is it a good idea to use making games on unity as a means to progress into software engineering?

[naive pawn]

doing is a supplement to reading, not a replacement

[swift crag]

You can also use Mathf.Remap to calculate an angle

wait, that doesn't exist lol

i'm thinking of the shader graph node

[silver flicker]

lol

[naive pawn]

damn, i got so excited 😔

[silver flicker]

too much knowledge

[swift crag]

float progress = Mathf.InverseLerp(0, raycastCount, i);
float angle = Mathf.Lerp(0, 360, progress);

That's basically what a remap does

[rich adder]

understanding c# will make you understand how to read/use properly any API including unity..

[silver flicker]

i see ok

[carmine sierra]

yeah i get that, but i mean the plethera of unity exclusive things

like all the methods aand components you need to understand

[naive pawn]

unity exclusive things can only be used in unity

[rich adder]

thats what the manual is for

[naive pawn]

but the concepts will take you much further

[summer stump]

Which are called an API. Learning how to use an API will help in anything

[carmine sierra]

yeah but i feel like the concepts are what take up much less time to learn

[naive pawn]

you haven't learnt either at this point

you need to learn both together

if you just learn the concepts, you can't apply that to actual code

[carmine sierra]

ive learned a bit of c#

[rich adder]

a bit is not enough

[naive pawn]

if you learn just the specifics for unity, you can never adapt and improve and apply that knowledge to other scenarios

you need both

[naive pawn]

(this is what computer science is)

[rich adder]

learning c# without any big frameworks is the best service you will do to yourself, everything else will make way more sense

[carmine sierra]

really? i havent encountered any c# issues that im aware of since i started this new project

just unity stuff

[rich adder]

I can name 3 just by looking at your posts lol

[naive pawn]

haven't you been asking about c# stuff this entire time

[carmine sierra]

i dont think so

just unity methods i dont understaand

[summer stump]

The "unity things" you had issues with were actually c# issues

[naive pawn]

any question about scripting in unity is a question about coding, and unity uses c# for its textual scripting

[summer stump]

Understanding c# would have made you able to resolve them

[sonic dome]

why is this my moment now working properly?

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

public class Move : MonoBehaviour
{
    public Animator body;
    private Rigidbody2D rb;
    private SpriteRenderer sr;
    public float speed;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        sr = GetComponent<SpriteRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        if(Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow)){
            rb.velocity = Vector2.right * speed;
            sr.flipX = true;
            body.SetBool("Walk",true);
        }
        if(Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow)){
            rb.velocity = -Vector2.right * speed;
            sr.flipX = false;
            body.SetBool("Walk",true);
        }
        if(rb.velocity == new Vector2(0,0)){
            body.SetBool("Walk",false);
        }
    }
}

this is the code

[carmine sierra]

could you tell me please cause then i can go to learn c#

[summer stump]

#💻┃code-beginner message

This would be a c# understanding issue

[naive pawn]

if you know c#/programming, then you would know how to read documentation and extract the necessary info from them

your problems are not unity-specific

[carmine sierra]

that one tbh i was focusing on the lines beneath since i thought the lines above were fine

[naive pawn]

you don't have the fundamental skills for programming, yet
go get them

[carmine sierra]

if that makes sense

[swift crag]

well, you also have problems with understanding how positions and directions work

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

[rich adder]

at least for copy and pasting code

[swift crag]

the documentation talks about these

[carmine sierra]

but that is not a c

thing is it?

c#

[naive pawn]

you've been told many times

[summer stump]

It is a math thing

[naive pawn]

if you understand programming, you will know where to find the information needed.

[carmine sierra]

yeah but i dont see the c# errors ive been told about yet

[summer stump]

Basic logic that applies to all programming

[carmine sierra]

direction vs vector?

[naive pawn]

errors ≠ issues
you lack fundamental understanding right now.

[rich adder]

knowing c# wont magically teach you about vector3s but you will understand how to use in the code once you do..

[swift crag]

you currently don't know what you don't know

[carmine sierra]

alr if everyone thinks so ill do thaat

[summer stump]

Yes, knowing vector mathematics is not unique to c# or unity or even programming

[carmine sierra]

but should i do that before even movving to the unity learn course

[summer stump]

But it IS very common in programming (especially game dev) of course

[sonic dome]

🥹 i got burried

[rich adder]

me, starting with reading c++ source engine code without a lick of coding exp

[summer stump]

Explain your issue a bit better please. In words preferably

[carmine sierra]

c# or unity learn first

creaate with code

[summer stump]

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

And then
https://learn.unity.com/pathways

[carmine sierra]

okay thanks

[rich adder]

C#

[summer stump]

This is pinned in my clipboard haha

[rich adder]

they should pin the w3schools one here its decent

[sonic dome]

i have attached a video below i wanted to show that the player suddenly stops moving forward when i go back and then go forward again then it works

[sonic dome]

replying to this cuz got burried

[summer stump]

What collider shape are you using for the player?

[sonic dome]

box2d

[summer stump]

Try not using a box, instead a capsule

[naive pawn]

that's probably not related to your code, are you using a composite collider for your tilemap

[sonic dome]

okk let me try

[rich adder]

are you using tilemap ?

try also using a composite collider on it
oh dang my discord just updated lol 🦥

[silver flicker]

Hello again, im trying to iterate raycasts at intervals of 15 degrees around a circle, but this code doesn't seem to work,

[sonic dome]

oh great works fine now thanks

[silver flicker]

how do you paste small blocks of code in the code format

[naive pawn]

            Debug.DrawRay(transform.position, new Vector3(0, 0, i * 15) * distance, Color.red);
        } ```

Thats it

[rich adder]

cs goes on its on line

[silver flicker]

im trying to iterate raycasts at intervals of 15 degrees around a circle, but this code doesn't seem to work

oh ok

[naive pawn]

new Vector3(0, 0, i * 15) is just vectors pointing up at various heights

[silver flicker]

I was wondering about that, how do you translate that to rotation?

[naive pawn]

you aren't rotating anything there

[naive pawn]

well first off use Vector2 since you're doing 2d stuff

then you could rotate that or use trig

[silver flicker]

Ok, I'll look up some more stuff. Thanks

[naive pawn]

there's no method to rotate actually im just dumb

just use trig

cos = x, sin = y

[silver flicker]

thats what I was looking up lol

[naive pawn]

keep in mind they use radians

[rich adder]

you could do

   for (int i = 0; i < 360; i += degreeIncrement)
   {
       float angle = i * Mathf.Deg2Rad;
       Vector2 direction = new Vector2(Mathf.Cos(angle), Mathf.Sin(angle));
       Debug.DrawRay(transform.position, direction * radius, Color.green);

   }```

I think

[silver flicker]

I think Ive used some method like rad2deg or something

that'd be the method

Ok, I think I understand that

Math time, thanks guys

[naive pawn]

also note that this starts at the right and goes counterclockwise (like polar coords)

if you need it to do something else then you have to apply an offset or a factor

[silver flicker]

Ok, any orientation should work

[little forge]

how does terrain pixel error work

if you get from 5 to 15, you won't rly notice the difference, but the triangle amount will go down ALOT

but as you increase it to like 25-30, terrain becomes less curvry but only far from player

and as you set it to 200, the entire terrain turns low-poly

[eternal needle]

Yes there is. Quaternion * Vector will rotate it

Could construct the quaternion with Quaternion.Euler then apply that to the current direction vector

[naive pawn]

i meant an actual c# method on Vector2

that was what i was thinking of

but yes quaternions are a thing im aware i just don't know how to use them lol

[swift crag]

this is not what I suggested doing

#💻┃code-beginner message

[swift crag]

this is creating a vector whose Z component is 15 * i

so it is a vector that points forward

[swift crag]

they're rotations. you use them to rotate things

[naive pawn]

i know what they are. i know what they're used for. i don't know how specifically they're used, i haven't worked with them, so i wasn't comfortable recommending them

[swift crag]

ah, fair enough

[summer stump]

First three variables give a direction, fourth is the amount of twist around that direction

But generally you just DON'T use them directly

[naive pawn]

noooo im not ready

[swift crag]

This is not correct.

[summer stump]

Ah, that was how it was explained to me. I dunno I guess

[swift crag]

consider this 90 degree rotation I made in Blender, followed by another 90 degree rotation (both around the Z axes)

[swift crag]

to be fair, it's...a bit inscrutable

[naive pawn]

oh what the hell....

[swift crag]

fortunately, quaternion math is completely irrelevant here

it should have just been called Rotation

[summer stump]

So, x, y, z are colinear with the axis of rotation; w describes how much rotation around that axis in a non-linear fashion. The constraint here is that the total has to have a 4d length of 1, so as the amount of rotation changes, the length of x, y, z have to change inversely.

Yeah, I simplified what I was told incorrectly

And misremembered. This was from a while ago

[magic panther]

For the love of god I don't know how to make a raycast from the gun's front to check what it hits. I asked chatgpt and he gave me this broken bs. Can someone tell me how this can be done?

Gun Code -> https://hatebin.com/ztagsogdlj

[swift crag]

yeah, it's something close to what you described

[timid oriole]

When creating a scriptable object do you guys use enums?

[magic panther]

the ray starts from this Y position. I have too many questions for this code, there's gotta be a simpler way to do this

[swift crag]

just use firePoint.forward

[slender nymph]

enums aren't something specific to scriptable objects, nor is the inverse relationship specific to that. use enums where appropriate

[swift crag]

line 44 is particularly bogus

Vector3 worldCenterPoint = transform.TransformPoint(centerPoint);

centerPoint is a world-space position, since it uses firePoint.position.y

[magic panther]

yeah, that's the chatgpt code

[swift crag]

so throw all of that hallucinated code out and just do...

Vector3 origin = firePoint.transform.position;
Vector3 dir = firePoint.forward;

[magic panther]

what do we turn this to to make it work

[little forge]

Vector3 rayStartPost = gun.transform.position + gun.transform.forward * (gunLength/2);
if (!Physics.Raycast(rayStartPos, gun.transform.forward, out RaycastHit hit, maxRayDistance)) return;
hit.Succ();```

[swift crag]

Make sure that your firePoint transform is rotated properly.

[magic panther]

also I'm guessing I delete centerpoint?

[timid oriole]

I know that my question is when creating sciptctable objects do you guys use enums because I have seen multiple people on youtube say you must use them instead of normal variables

[willow scroll]

To make the Raycast out of the gun's front, you have to the take your gun's long side (the gun without the handle, not sure how it's called), and cast a Raycast from its tranform.position in its transform.forward direction, or whatever its axis is

[swift crag]

It looks like this code is trying to figure out a "forward" direction without actually using the rotation of firePoint

by instead using worldFirePoint - worldCenterPoint

this is completely unnecessary

[slender nymph]

again, use enums where appropriate. there is no specific relationship between enums and scriptable objects.

[magic panther]

this is where firepoint is

inside the gun, so it has a tiny offset from 0,0,0

[timid oriole]

again I'm asking is it typical to use them almost always for scriptable objects as that is what I've been told I'm not saying you can only use it there?

[magic panther]

I'm guessing .forward since the gun is aimed in the Z direction from the start

but what about the rotation

[slender nymph]

jesus christ what part of "there is no specific relationship between enums and scriptable objects" do you not understand?
that is the answer to your question

[willow scroll]

No. It's not. They have already answered you that there is no reason for you to use enums specifically for ScriptableObjects. You use them in the same cases as when working with normal MonoBehaviours

[magic panther]

rotate by gun rotation and we're good?

[timid oriole]

Then why did CodeMonkey and a few other tutorials say you should always use it what is that relation if its being said ?

Just junk?

[little forge]

if you have a firepoint, you can do this then

int maxRayDistance = 150; // 150 unity units
if (!Physics.Raycast(firePoint.transform.position, gun.transform.forward, out RaycastHit hit, maxRayDistance)) return;
Debug.Log(hit.collider.gameObject.name);```

[slender nymph]

link a timestamp where literally anyone is saying that

[timid oriole]

I will

[willow scroll]

I have no idea what other tutorials said. It's either that they're wrong or you've misunderstood them. I think the latter.

[summer stump]

I dunno the subject, but codemonkey is... not good

[magic panther]

I'll give it a go

I just need a raycast forwards of firepoint relative to the gun that logs the first thing it detects

[timid oriole]

https://www.youtube.com/watch?v=-PT-LADWymI&ab_channel=CodeMonkey he says it around 46 seconds

he implies it is bad practice to use strings

[slender nymph]

i'm calling it now before i watch the video that the tutorial was actually telling you to use an enum because it was the most appropriate data type for the information you are trying to store as a variable and had literally nothing at all to do with the variable being on a scriptable object

[swift crag]

notably, he's not writing a ScriptableObject here

[little forge]

if you use raycast, it will anyways return the first object ray met

[swift crag]

he's demonstrating that you should use enums, not string constants

[timid oriole]

In his scriptable object video he only uses enums

[willow scroll]

There should be no reason to create a variable for the fire point, as you can simply cast the Raycast from the gun's position

[swift crag]

then why did you link a completely unrelated video

[magic panther]

it says cube

[little forge]

well, he wants some kind of firepoint

[swift crag]

It's going to rain tomorrow. What color are my pants?

[timid oriole]

it was the video I was watching before to get an understanding of what enums were in the first place

[little forge]

which might be above or sideways from guns position

[naive pawn]

you aren't wearing any

[magic panther]

because it's inside it, right?

[swift crag]

close: shorts

[slender nymph]

are you conflating using enums instead of strings with using enums instead of any other type of variable? because enums are just a handy way to identify something using a compile time constant that isn't a string

[naive pawn]

so you aren't wearing pants, i got it right then

[swift crag]

please show us the actual video, not another unrelated video that doesn't say what you said it did

[little forge]

don't forget that raycast won't return the collider which is bounding the start point

[swift crag]

yeah, a 3D raycast will ignore those

[magic panther]

how do we handle the case in which the gun is jammed inside an object? (For now I don't need to render it separately)

[little forge]

so if you start shooting from inside a cube, cube will be ignored

[magic panther]

can we enforce this somehow?

[willow scroll]

Why would you?

[slender nymph]

isn't that only if the queries hit backfaces option in the physics setting is disabled?

[magic panther]

if the ray hits something and it's distance is less than 0.2f it won't fire

[eager spindle]

cant you just get a list of raycasted objects and also check which objet the gun is colliding with

[remote osprey]

Hello, everyone

[magic panther]

eliminating the ability to fire from inside or very close to walls

[timid oriole]

finding it

[magic panther]

so is there a way to enforce the start collision?

[eager spindle]

what does this mean

[willow scroll]

Not sure what you mean?

[eager spindle]

to enforce the start collision

[magic panther]

like, for the raycast to recognize the start collision instead of omitting it

[rocky canyon]

u said the same thing twice

[little forge]

it is disabled by default

[remote osprey]

If I create an instance using a prefab, does that mean that two instances of this prefab will have the same identity as each other?

[magic panther]

yeah

[swift crag]

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

I believe this is for mesh colliders in particular?

[willow scroll]

Instances aren't references. So no.

[swift crag]

I need to go test that carefully.

[remote osprey]

Thank goodness!

Thanks for the reply!

[eager spindle]

does it not do that by default? If your gun is inside the wall, you do a raycast from the gun to where youre looking at.

if the gun is inside an object, then the raycast will be the object the gun is in

[swift crag]

Don't let the player get so close to the wall, or start the raycast from further back

[slender nymph]

sure, but that doesn't mean it cannot be turned on to get that behavior

[magic panther]

btw @little forge what's the return for? Won't this cancel the update function?

[eager spindle]

so do you want the object inside the gun to be omitted?

or do you want the object inside the gun to stop the gun

[magic panther]

it ignores the object the raycast starts inside of

[rocky canyon]

if it doesnt hit anythign it returns

[magic panther]

I'd like it to recognize that

[timid oriole]

I can't find the video anymore damn

[rocky canyon]

!Physics.Raycast

[timid oriole]

It was a codemonkey tutorial I was following though but thats besides the point I guess if it doesn't make sense it doesn't make sense

And anthestiosity mentioned codeMonkey is bad why is that?

If brackeys is bad and code monkey is bad that's like 90% of the tutorials

[eager spindle]

ok so you

• do a RaycastAll https://docs.unity3d.com/ScriptReference/Physics.RaycastAll.html
• check if the gun is inside an object. if so, store the gameobject inside the gun
• loop through the raycastall result. if its the same as the gameobject inside the gun, skip it

[rocky canyon]

he's not necessarily bad.. he writes in a really condensed complex way.. doesn't explain some basic things he assumes u would know..

[willow scroll]

When you have a class, which your prefab is, simply assigning another class to it will make them both have the same reference

yourObject = yourPrefab;
yourObject == yourPrefab; // true

When you simply instantiate a prefab, it will create its instance, and removing the instance won't do anything to the prefab

yourObject = Instantiate(yourPrefab);
yourObject == yourPrefab; // false

Destroy(yourObject);
// yourPrefab is fine

[rocky canyon]

and plugs a utility library that he uses all the time

[magic panther]

idk who anthestiosity ( <-- forgot bro's username mb ) is but codeMonkey is great from my experience

[slender nymph]

my only issue with code monkey's tutorials is that he relies too heavily on his own libraries and expects users to install them to follow along with his tutorials. of course i haven't had to watch any of his tutorials in several years so 🤷‍♂️

[magic panther]

except from the library part, yeah

[summer stump]

Code Monkey is bad for BEGINNERS imo

[timid oriole]

ah yes you are right he had me sign up for his email list to get the things I needed to

[eager spindle]

i hate when guides ask you to download their frameworks

[timid oriole]

fucking annoying

[eager spindle]

executing third party code on your pc while not knowing how they got started

[summer stump]

He has OK code for intermediate and "advanced"

[eager spindle]

im making a tutorial series right now for C#, Raylib and Unity

no libraries other than in the base

[remote osprey]

So if I were to compare two instances out of the same prefab, would their == value be false?

[timid oriole]

whats your channel

[eager spindle]

not yet

[rocky canyon]

cool.

[eager spindle]

ill publish the full thing

its a bucket list thing

right now im making like 2 projects simultaneously so im gonna perish

[remote osprey]

Please do'nt perish just yet

You got 2 projects to finish!

[summer stump]

Learn.unity is always gonna be the best place to start, and codemonkey, brackeys, and others have clickbait channels that generally give bad practices to just get out content. Which is pushed by youtube itself of course

[magic panther]

I don't understand what I'm supposed to do.

[willow scroll]

Surely, when Instantiating a prefab, it creates a new GameObject. These GameObjects are completely different and return false when compared
||Note that by GameObject I also mean the type of the instantiated prefab, as Instantiate is generic||

[eager spindle]

ok your first task is to learn how to use RaycastAll instead of Raycast

you're using raycast right now right?

[remote osprey]

Thankyou for your repllyy!!! 🙏 🙏 🙏 🙏

[rocky canyon]

as a tutorial maker, i agree 🤣

[eager spindle]

RaycastAll returns all the objects that are hit by the line, not just one

very fun stuff

so take the first object in this array returned by RaycastAll

[timid oriole]

I hate unity learn but Im gonna give it another go because at this point I truly hate the youtube unity tutorials most of the time

[eager spindle]

unity learn doesnt do enough

I plan to teach unity basics then do guided projects

[rocky canyon]

it does plenty to make u learn the processes

[eager spindle]

for art assets ill prob plug kenney all in one assets

[magic panther]

yup

[rocky canyon]

once u get the basics its up to you to research specific topics

[timid oriole]

I mean what do we define as basics though?

[eager spindle]

neat, let me know when you changed Raycast to RaycastAll

[rocky canyon]

knowing how to read the docs.. write proper syntax, and be able to navigate the editor

[timid oriole]

okay so you think If I know that there is no point in untiy learn?

[rocky canyon]

once you learn that.. no not really

but im not saying don't finish em

b/c its structured in a way to work ur way up

[magic panther]

https://hatebin.com/thyvqoebcd

Still not detecting the entry collider. If I'm rushing just tell me

[rocky canyon]

i never even did the learn route.. wish i had of

[timid oriole]

so how did you learn

[summer stump]

Hard disagree

[rocky canyon]

self taught.. and reverse engineering assets

[eager spindle]

• c#, if/else, while, for, switch, classes and OOP, interfaces, preferably worked on other coding projects
• know how to use the editor(right click to move around, right click + wasdeq to move)
• know how to create gameobjects
• know how to move around game objects in the scene
• the concept of parenting gameobjects in the scene
• what a transform is
• what a component is
• attaching components to a gameobject
• how to make your own components
• how to use SerializeField and link your components together
• abusing static variables and making singletons

[rocky canyon]

i figured out how to do IK in about 30 minutes this morning

[timid oriole]

I know everything there besides static and singletones and interfaces

[eager spindle]

hot damn

[rocky canyon]

once you know how to search the internet.. and u know how to write code.. and read errors ur golden

[magic panther]

I got half of these down damn

[rocky canyon]

singletons and interfaces are important

i find it hard to do stuff like state machines and behavioural trees

but everything else. is pretty simplified.. u dont have to write pretty code.. just code that works tbh

unless ur working in a team.. then write prettty code

[summer stump]

Singletons are usually not recommended in non-game dev, at least not much, but they are very common and useful in games, especially in engines which consume Main

[willow scroll]

That's so cool

[timid oriole]

singletones?

damn I should learn then

[rocky canyon]

yes

u should 🙂

[summer stump]

Singletons. Not singletones

Yes, you should

[eager spindle]

you are in a good direction

class GameManager {
public static bool canMove;
public static GameManager instance;

void StartGame() {
  instance = this
}
}

...
class PlayerController {

  void Update() {
    if(GameManager.canMove) ...
  }

}

first variable in GameManager is canMove. you dont actually need to make a GameManager to use canMove. you can get it from the class name.

very fun stuff

[lone hamlet]

how to create an ocean using code (with high vfx)

[eager spindle]

then if you do decide to make a GameManager you dont have to use serializefield

[magic panther]

@eager spindle what's wrong here?

[eager spindle]

i looked at it

[swift crag]

📸 typo recorded

[eager spindle]

looks correct

your object might not have a collider

or might not be the exact same collider

[timid oriole]

don't you need a reference to the class? Or you don't because its public

[magic panther]

you mean the gun or the firePoint

[summer stump]

Nooooo
Nicholas, I typeod. It is SINGLETONS lol

[swift crag]

if you want really nice water rendering, you'd want to look at the high definition render pipeline

[magic panther]

the gun has no collider so it doesn't break the player and all the other things

[eager spindle]

in this case no. you can use GameManager.canMove and GameManager.instance without a serializefield

[rocky canyon]

HDRP water 🤤

[timid oriole]

because its public right?

[eager spindle]

they still need to be public but you dont need to getcomponent or serializefield

its because its public static

public static GameManager instance lets me use GameManager.instance without a serializefield

[swift crag]

you are mixing some important concepts up here...

[willow scroll]

Singleton's Instance is a static reference to the class, so accessing the variables from it is pretty much like accessing the variables from a static class

YourSingleton.Instance.anyVariable

[lone hamlet]

i know but i think you can use some math function to code it without touching to render pipeline

[rocky canyon]

TheClass.instance.Function();

[timid oriole]

so we could say like if GameManager.canMove == true) {audioclip.PlayOneShot(walkingsound);

[swift crag]

It lets you access the instance field from the class itself, rather than from an instance of the class

[rocky canyon]

GameManager.instance.canMove == true;

[swift crag]

It's true that this means you don't need to be given a reference to a GameManager

[timid oriole]

HUH?

[summer stump]

No, you are missing the instance

[willow scroll]

== true 😭

[summer stump]

You are accessing the type via a static VARIABLE

[magic panther]

also just a general question, because this applies to web development, but will I get good at C# by just making different stuff every day?

[timid oriole]

it was a bool no?

[summer stump]

Experience is good, yes

[eager spindle]

yes i learned a lot of unity and consequently game dev as a whole by doing dumb things

[summer stump]

It is already a bool. No need to use == to convert it to a bool

[rocky canyon]

you'll get better

[languid spire]

`not necessarily

[eager spindle]

like making a skibidi toilet fan game

[swift crag]

get well soon 🙏

[willow scroll]

This is not necessary. Simplify your code by changing

yourBool == true   =>  yourBool
yourBool == false  =>  !yourBool

[timid oriole]

Ah yeah ur right should be just what whatever and just use !thingy if false or thingy iuf its true

brain fart

[magic panther]

what could be the issue outside the gun lacking a collider

[magic panther]

how do we change better to good

[eager spindle]

is firepoint null? is firepoint.getcomponent<collider> null? could you store your collider in a variable rather than using getcomponent in the for loop

[summer stump]

Constant learning

[rocky canyon]

erm, it depends on your routine. and what ur chosing to learn.. when

i can't say.. its different for everyone

[old rivet]

Anyone here who can help me with object pooling?

[summer stump]

https://dontasktoask.com/

[magic panther]

firepoint is a transform from inside the gun

[willow scroll]

https://dontcrosspost.com/

[eager spindle]

when you work in the game industry you'll join a lot of companies with their own solutions for things, or you might even make your own solution yourself.
by solution it could mean making your own engine or unity extension

this is how people go from better to good

[magic panther]

What do you mean by routine

[eager spindle]

because it challenges what you've learned and makes you google a lot of stuff

a lot more than just staying indie

I learned how to make unity extensions and unity GUI because Ineeded some stuff automated for my team

[rocky canyon]

the steps you take each time you study/learn/work

[timid oriole]

What exactly is static is a method static or a class? What does that even do exactly?

[queen adder]

hello would anyone be able to help me out with coding i am fairly new :3

[eager spindle]

how may we help

[old rivet]

Ok so
I'm making a simple space game
Where 3 sizes of asteroid spawn
And when player shoot them
Larger one split into medium
While medium into small
And small one destroy

I'm destroying when using destroy(gameobject); but I heard game pooling is way better for massive spawn and despawn

So I'm wondering how I will able to achieve it

I can send my asteroid and asteroid manageer script (spawn asteroid randomly) here

[slender nymph]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/static

[magic panther]

think, make, fix with the help of others and the internet most of the time, learn from mistake, repeat
to simplify ofc

[queen adder]

so like i wna make an silly fighter jet game yk

3d

where u can like fly fighter jets

fight others

yk

[eager spindle]

first step is to make a script that detects when the asteroid gets shot, do you have that right now?

[rocky canyon]

please make coherent and full sentences

[eager spindle]

once that happens, when the asteroid gets shot, instantiate two more objects.

[languid spire]

you mean you are Cloning Asteroids, object pooling will not help you here

[eager spindle]

apologies for interrupting you but when you write a programming question rather than sending multiple messages, write it like an email. you only get one message so include your whole message in it/

[magic panther]

Maybe something with the actual code

[old rivet]

Ye I'm sending 1-2 minutes

[timid oriole]

this line here "Use the static modifier to declare a static member, which belongs to the type itself rather than to a specific object. " is like japanese to me

[slender nymph]

there are beginner c# courses pinned in this channel. start there if you do not understand how the language works

[queen adder]

oh ok my bad.

[old rivet]

Not cloning
It's like when a larger asteroid gets hit
It gets deleted and it spawn 2 more

[willow scroll]

You cannot use the new operator to create a static class, and these classes can only contain static variables.
You have to create normal classes to access their non-static methods or variables.

Nicholas nicholas = new();
nicholas.Eat();

While the static classes don't support that, and their methods are accessed directly, without the reference.

NicholasUtility.CreateNew();

[summer stump]

Any can be. Method, class, and variable can all be static

[queen adder]

Would you be able to help me out regarding my idea.

[languid spire]

I do know how Asteroids works and I'm telling you object pooling is not necessary here

[timid oriole]

this sorta makes sense

My brother knows C & JAva would he be able help me or is c# to different

[naive pawn]

static in class and static in members is slightly different;
a static class can only hold static members, that's all it does
static on members actually has an affect
a static member is accessed through the class directly rather than through an instance

[little forge]

i still need help with this

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/members

[willow scroll]

Yeah, I know. You can also have static methods in non-static classes, which also don't require the instance of the class and can be accessed directly

[timid oriole]

Yep I don't know what half of those do back to the basics it is then

[naive pawn]

c# is c-family, they have similar fundamental syntax, but c# is significantly different in paradigm and structure from c

it's quite similar to java though, java just doesn't have static classes (which doesn't detract any functionality, you just can't enforce not having non-static members. you can restrict construction though)

[swift crag]

did you try reading the descriptions

[little forge]

yes

[old rivet]

Yes probably but it's a part of my project

[willow scroll]

I suppose, Java is pretty the same

[swift crag]

importantly: using static when declaring a type doesn't add any functionality -- it's strictly there to prevent you from adding any non-static members

[little forge]

why do you need to enforce class to be static tho

[eager spindle]

doing it without static

public class GameManager {
  public bool canMove;
}

public class Enemy {
  [SerializeField] GameManager manager; // drag gamemanager here!
  public void Start() {
    if(manager.canMove) ...
  }
}

doing it with static

public class GameManager {
  public static GameManager instance;
  void Start() {
    GameManager.instance = this;
  }
}

public class Player {
  void Start() {
    if(GameManager.instance.canMove) ...
  }
}

static variables explanation. GameManager has a static variable called instance, which keeps track of the one and only GameManager. the static variable instance is not depending on anything, so you dont need to create a GameManager to access instance.
lets say you have 100 players in the game. its not good practice to drag Gamemanager into every player if it were a serializefield, so you can use a static variable

[timid oriole]

I'm going to seems like a there is a collective opinion that I should really get much more understand of c# as a whole then move to unity

[eager spindle]

apologies for big block

[eager spindle]

suree, do DM me and I can guide you through the process

[swift crag]

You need to have a decent handle on programming, yes.

If you don't know any of the words you're going to have a miserable time of it

that's what Unity Learn is there for

[timid oriole]

that explains a lot.

[willow scroll]

Not quire sure what you mean

[eager spindle]

yep. if you want to have a good handle on c# you want to make a few practice projects. you could try making your own engine in Raylib for c#

[little forge]

he means you can't add non-static methods or variables into a static class ig

[eager spindle]

which will get you a lot of practice

[naive pawn]

i would recommend against dm help especially when the support server exists

[old rivet]

[timid oriole]

codepaste my man

[timid oriole]

yep thanks for your help

[swift crag]

When you add static to a member, you're fundamentally changing how you can access the member. It lets you access the member from the type itself, instead of from an instance.

When you add static to a type, you're not adding any new capabilities to it. You're just saying "no instances may be created".

[eager spindle]

this is more for a guided project than a problem everyone encounters

[naive pawn]

static class X {}
class X {}
```are functionally equivalent. the `static` only comes into play when non-static members are added

[swift crag]

oh y'all do it the other way round here?

on desktop you can expand the message

For everyone to download it on their device?

[summer stump]

No, actually I tested this up to about 2k lines

But it still requires download on mobile.

There is a reason paste sites are the rule

[eager spindle]

make a screenshot of the code

No

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

[summer stump]

They want to make object pooling

[old rivet]

https://gdl.space/aronozejum.cpp ?? like this 😿

[willow scroll]

You succeeded! ||I have not stopped believing in you once||

[summer stump]

Yes 🎉

[old rivet]

everything is working fine , just instead of delete i need to apply object pooling

[summer stump]

Ok, I don't see any object pooling happening.
What did you try so far?

Have you looked into the ObjectPool type that unity provides?

[old rivet]

https://gdl.space/favokoninu.cs

idk how to do it with 3 objects

[eager spindle]

for object pooling you'll need an array of gameObjects first.
GameObject[] largeAsteroidPool = new GameObject[10]

under start, set all elements of the largeAsteroidPool to a new large asteroid. set this asteroid to be inactive.
when you need an asteroid, set the asteroid to be active and set the position of the asteroid. when you dont need the asteroid, set it to be inactive.

[languid spire]

if you insist on doing this you will need 3 pools

[old rivet]

i mean i know problem i face is when , 2 medium asteroid spawn from large asteroid destruction

[naive pawn]

wouldn't it be 3

[eager spindle]

to do this for the small and medium asteroid pool make 2 other arrays

[old rivet]

https://gdl.space/favokoninu.cs i hab 3 arrays

look

[eager spindle]

ok so small problem this is a List

i guess you can use a list

[eager spindle]

but dont add or remove from this list

or itll defeat the purpose of an object pool

[slender nymph]

why not use unity's built in object pooling class?

[naive pawn]

seems pretty reasonable to add to it if you don't have enough objects...

[eager spindle]

tbf object pooling is an important thing to learn

[old rivet]

they hab?

[summer stump]

I think this is a school project

[eager spindle]

yea just dont do it every frame

and choose a good starting number so it doesnt change too often

[languid spire]

did you do no research?

[eager spindle]

personally I havent used it before, unity's object pooling system

[naive pawn]

you've been told this quite a few times....

[slender nymph]

i can't imagine that someone who is pretty much incapable of reading instructions is going to be able to follow along with your instructions for creating an object pool

[naive pawn]

yeah this is kinda why i don't like people opening up their dms... community support is good because there's an entire community, able to give multiple perspectives and opinions and suggestions...

[old rivet]

i m on version 2021.3.29

[naive pawn]

going into a community support server to find a personal tutor just nullifies the benefit of asking in a community to begin with

[old rivet]

i have these 3 scripsts to change to succesfully apply object pooling i will share

[languid spire]

then why are you even in this conversation?

[eager spindle]

teaching the user the basics of object pooling rather than just directing them straight to the library

[naive pawn]

basics ≠ internals

[languid spire]

but you said yourself you've never used it so how much do you expect to teach?

[eager spindle]

im talking about making a normal object pool rather than using unity's internal object pool

[naive pawn]

teaching to implement isn't the same as teaching to utilize

[slender nymph]

sure but if the first thing you try to change is making them use an array instead of a list, well that's not a very good or even relevant change so is your teaching really going to be worth it to that user?

[eager spindle]

up to them

i havent had the need to expand my object pool before

just choose a good fixed number at the start

[slender nymph]

if you want to make a proper object pool, you'd be using a queue not an array anyway 🤷‍♂️

[old rivet]

i have these 3 scripsts to change to succesfully apply object pooling i will share
https://gdl.space/efociwubek.cpp (Asteroid script control asteroid spliting and destroying on impact with bullet)
https://gdl.space/uyeqexaton.cs (object pooling)
https://gdl.space/awamojofix.cpp (Asteroid manager which spawn random asteroid at random location)

[eager spindle]

I see some beginners asking "how do I make game" rather than "how do I do ...", they dont ask precise enough questions and they're just ignored by the community because they don't know how to break their game down, and even when I do help them in chat people from the sides constantly bombard them with shittalking because they're doing something wrong

not very fun for them

[elder osprey]

How would I make it to where multiple scripts can reference the same instance of a script across scenes? I have a settings menu in the main scene of my game, each slider and toggle has its own script that handles its functionality. Currently I am trying to make a main menu, and my idea for applying the settings across scenes is to use a script which holds the values of each of the settings. I am unsure of how to make a single instance of the script accessible across different scripts.

[eager spindle]

across scenes? when you go across scenes the GameObject is destroyed

[languid spire]

DontDestroyOnLoad

[old rivet]

😦😔

[eager spindle]

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

[elder osprey]

I am not using a gameObject, I am using a base C# script that sits in unity's assets.

for example

[modest dust]

Wouldn't a Stack be better for an object pooler?

[eager spindle]

how is this object created?

[slender nymph]

i personally use a static class to store the settings for my game and load using the RuntimeInitializeOnLoadMethod attribute and save when settings have been changed

[languid spire]

Technically, yes

[slender nymph]

queue and stack are completely interchangeable for an object pool, queue just lets you get the oldest object in the collection first whereas stack gets the newest

[naive pawn]

asking good questions is a skill that needs to be developed alongside everything else. there's gotta be a place to practice that

[elder osprey]

So, how would other classes be able to access a single instance of this static class?

[slender nymph]

there is no "instance" because the class is static

a static class can only contain static members

[languid spire]

Have you still not learnt C# basics, via the Class name

[naive pawn]

"single instance" is a singleton, not a static class

[eager spindle]

public static class Settings {
  public static int volume;
}
...

Settings.volume

this is a static class

[elder osprey]

I understand now, sorry.

[old rivet]

anyone?

[eternal needle]

You didnt actually ask a question in that block.

[eager spindle]

this does look like object pooling so what do you want changed

[old rivet]

idk what changes to commit in asteroid and manager script

[naive pawn]

changes to achieve what

[eager spindle]

commit to where, the repository?

what do you want to achieve

[elder osprey]

I know a decent amount of C# using monobehaviours and scriptableobjects; however, this is my first time using custom static classes.

[eternal needle]

Take a minute, and actually think what you're asking. You showed code and said "what do I change?". No one knows what your game or issues are

You'll get much better responses if you actually can ask something.

[languid spire]

Sorry but this is basic MS Learn C# 'Hello World'

[eager spindle]

the ms docs use a lot of terms unfamiliar to new programmers, while it is correct it doesnt teach beginners

[naive pawn]

how do you reference a MonoBehaviour to extend it, or a Collider to get a collision, or a RigidBody to get a component

[eager spindle]

I understand the docs now but not 4 years ago when I started unity and programming

[naive pawn]

by name

[old rivet]

why istead of using the pool its creating new objects?

[naive pawn]

you told it to
in SpawnAsteroid, you're calling Instantiate, that creates a new object

[eager spindle]

it calls SplitAsteroid which instantiates an object rather than getobject from the pool

[elder osprey]

Previously, I was unaware of what the static modifier did, I understand now. I have understood since uldynia provided an example.

[naive pawn]

it.. doesn't actually affect accessing the class

static on a class doesn't really change anything

[old rivet]

what should i do instead?

[eager spindle]

it forces people to make variables static

[naive pawn]

get an object from the pool

[eager spindle]

look at the function you created in the objectpooling script how do you get an object from the pool

[naive pawn]

when developing. it doesn't change how you use the class at all

[eager spindle]

yea it only affects your teams who want to inherit the class

[willow scroll]

It usually takes more time to create beginner-friendly explanations

[eager spindle]

im willing to do that

[old rivet]

Im like very new to this . can you explain how?

[eager spindle]

public static class Settings {
  public static int volume
}
public class Settings {
  public static int volume
}

are the exact same thing. however,

public static class Settings {
  public int volume
}

is invalid because you try to put a variable that's not static, into a class that is static

[summer stump]

You have the static accessor and the method. So Type.Accessor.Method

I don't remember the names

[eager spindle]

most of my work is indie so i dont bother making static classes, only static variables
but if you want to force someone to only use static variables then go ahead use static class

[summer stump]

Well they serve very different purposes. Not sure how being indie affects the choice

[eager spindle]

so in future if someone wants to

public static class MoreSettings : Settings {
}

they must keep everything static

[eager spindle]

no one inherits my code so I don't have to think too much about public/private accessors

[naive pawn]

wrong person

[willow scroll]

What I also not like about many tutorials is providing 200-line code blocks for the methods, which can easily be explained in much less lines, and, perhaps, several examples. You then have to find the explained method in this huge snippet and check out all the methods related to it. So, please, make sure to note that when doing yours!

[naive pawn]

access the pool, find one that's inactive, put it in the right place, and enable it

[summer stump]

No one does to me either... but that doesn't mean I don't care about proper code structure

[eager spindle]

yep I make guided projects rather than just paste a block of text and expect them to know everything, or make then download a library and show then 1% of the code in the repo

[elder osprey]

Alright, just to confirm. If I were to say: Settings.leftHanded = true; in a script. Then I did Debug.Log(Settings.leftHanded) from a different script, it would log "true" in the console?

[eager spindle]

yep

[elder osprey]

Bet

[willow scroll]

It depends.

public bool leftHanded
{
    get => _leftHanded;
    set => _leftHanded = !value;
}

||Naming violation||

[eager spindle]

rare case but yes that's true

[elder osprey]

Also, if the script is static, do I need to initialize the script at runtime. And if so, how could I do this? This is what I have currently ```cs
public static class Settings
{
public static bool fullscreen = false;
public static bool leftHanded = false;
public static bool highContrast = false;

[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]
public static void RuntimeInitializeBeforeLoad()
{

}

}```

[eager spindle]

nope you dont

[willow scroll]

Why would you do this?

[naive pawn]

anything that's static is loaded when the class is loaded

[eager spindle]

thats the first time ive seen that macro

[naive pawn]

your Settings doesn't interact with unity at all

it doesn't need unity to tell it to load

[willow scroll]

Static classes just exist always..

And so they are not related to Unity at all

[elder osprey]

Thank you.

[brave robin]

[RuntimeInitializeOnLoadMethod] is very useful if you want your static to have methods that immediately run, like Awake or Start does. I use it often, when I need that

[naive pawn]

couldn't you just use a static block

[brave robin]

But to be safe I use the option for 'after scene load'

[brave robin]

A static block?

[elder osprey]

Oh that's perfect! I could use this to load settings from a file.

[strong wren]

how do i fix this?

        {
            ReloadAR();
        }
    }

    public void ReloadAR(float ReloadAmmount)
    {
        ReloadAmmount = ARMagSize -= ARAmmo;
    }```

[naive pawn]

oh wait c# uses a different form of these, it's a static constructor instead

[brave robin]

If you need your initializing method to access anything in the scene, use this to be safe [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.AfterSceneLoad)]

[naive pawn]

class X {
  static X() {
    // run on class load
  }
}

[eager spindle]

you need to put something in ReloadAR()

a float

[naive pawn]

Static constructors

[strong wren]

in the ()?

[eager spindle]

yep

put a number

[strong wren]

oohhh

[languid spire]

do you not see the difference between
ReloadAR();
and
ReloadAR(float ReloadAmmount)
?

[naive pawn]

you probably don't want ReloadAR to have that parameter

it isn't doing anything useful

you're just reassigning it

[strong wren]

wdym?

[brave robin]

You can, but the runtimeinitializeonload attribute has extra options for specifying when you want the method to run. Like the option I mentioned above will ensure it doesn't run until after the scene loads, so that your static method can access stuff in the scene without issues

[naive pawn]

your method ReloadAR takes a parameter, then it immediately throws away that parameter

it isn't doing anything

[strong wren]

kk

ima just make a private float outisde of the paramater

[frank delta]

is there any reason why the post processing changes by script is not showned?
here is the script, it is fairly short

public class PlayerGForce : MonoBehaviour
{
    Entity.EntityFastMovers Entity;
    [SerializeField] Camera cam;
    [SerializeField] Volume volume;
    Vignette vig;

    void Start()
    {
        Entity = GetComponent<Entity.EntityFastMovers>();
        volume.profile.TryGet<Vignette>(out Vignette vignette);
        vig = vignette;
    }

    private void FixedUpdate()
    {
        vig.intensity = new ClampedFloatParameter(Entity.GetVelocity() / Entity.MovementData.maxSpeed, 0.2f, 1);
    }
}

[slender nymph]

because you are not changing any values on the settings in the profile. you output your vignette settings to a local variable then immediately assign a different object to that local variable

[frank delta]

oh right

thanks!

[slender nymph]

actually that last bit was wrong, you are assigning the local variable to the field

i misread the code

[frank delta]

what should I change then?

I thought vig is already a reference to the volume profile vignette component

[slender nymph]

have you confirmed that the values you are using are what you expect them to be?

[frank delta]

yes, you can see in the video that the value changes

[eager spindle]

not reliable advice but do it the dumb way and use TryGet every frame. last time I worked with volumes this is what examples online did.
vig could be a copy of vignette

[frank delta]

I will try, thanks!

[slender nymph]

if it were a copy it would need to be assigned back (it doesn't)

[rich adder]

its so much easier just to make another profile with the settings you want and just blend between the 2 Volumes with separate profiles using the weight slider

[frank delta]

sadly does not work

[eager spindle]

what about enabling override for vignette before starting?

[frank delta]

how so?

[eager spindle]

tick the box for vignette and try again

it wont change much but its probable

[frank delta]

changes nothing

[frank delta]

huh alr, I will do that

[eager spindle]

yea I think this is the better solution. the new volume that overrides the global volume should not override anything besides vignette

things will get tricky if you're gonna use multiple volumes (> 2)

[rich adder]

just make sure the one you want to fade in has higher priority

[slender nymph]

you probably need to pass true to the ClampedFloatParameter constructor for the overrideState parameter which defaults to false

[frank delta]

I have done that, not the case

[slender nymph]

hey remember when you asked that question in #archived-code-general and were provided an answer?

[rich adder]

oof

[solar canyon]

My bad I didn't see it

[long jacinth]

copied these from my old code for an aiming system but how do i replicate this code with what i have new

[slender nymph]

okay well i recommend going through the basics of c# if you still don't understand what you did wrong. there are beginner courses pinned in this channel

[frank delta]

@rich adder blending works! thanks a ton, and everyone else too

[rich adder]

nice!

let the others have their coding help

[long jacinth]

if(Gun.transform.rotation < -90 || Gun.transform.rotation > 90)

[rich adder]

back to unity code

[frank delta]

use a code block my guy

[long jacinth]

i found out the problem how can i do this but working

[rich adder]

rotation is not a single number

[frank delta]

but for short ones,

do this

[eager spindle]

do look into how transforms work

[long jacinth]

how

[rich adder]

rotations are stored as quaternion @long jacinth

[frank delta]

(your stuff goes here)

[eager spindle]

use the backtick `, not apostrophe '

[long jacinth]

thanks

[frank delta]

gucci

[long jacinth]

hmm how do i convert it

[frank delta]

so basically
rotation on the editor xyz are essentially Vector3

but for reasons, they use Quarternion

to use the Vector3 version, do

Quarternion.Euler(vector3)

[rich adder]

which part of the rotation do you want?

[eager spindle]

transform has a few things you can use.
transform.position, a Vector3 which is the object's position
transform.eulerAngles, a Vector3 which is the object's rotation in degrees. look into quaternions for the better way to store rotations.
transform.scale, a Vector3 for how big the object is.

fun resources to read:
https://docs.unity3d.com/ScriptReference/Transform.html
https://www.youtube.com/watch?v=zjMuIxRvygQ

[rich adder]

oh nvm then

[eager spindle]

read the docs for transform

it is very fun

[frank delta]

anyways it is like

||if(Gun.transform.rotation.eulerAngles.(youraxis) < -90 || || Gun.transform.rotation.eulerAngles.(youraxis) > 90)||
to fight certain spoon feeding allegation

[eager spindle]

if you have any questions about transform let us know.
the purpose of transform is to describe where an object is, how it's rotated and how big it is.

[pastel dome]

ayo, how does on one properly create a network behavior script? you just create a mono behavior and change those words to network behavior?

[rich adder]

yes

those words meaning something

its called a parent class

maybe you should not be starting with networking..

[pastel dome]

ya thank you

[long jacinth]

yo guys thanks ima watch that video about quaternions

[eager spindle]

funni math stuff

[frank delta]

quaternions are hell

I have yet to master it

yaw pitch and roll bull crap 😭

[eager spindle]

in most cases on unity you can get away with using eulerangles, but if you do go ahead with your own engine youll learn to love quaternions

[frank delta]

im struggling to create my 2D engine over here 😔

[rich adder]

you dont really need to know how quaternions work

[eager spindle]

salutations

[rich adder]

just know what they're for thats it

[eager spindle]

we love opengl

[long jacinth]

ok thank you

[frank delta]

all fun until opengl batching limit

and their dumb web gpu usage

[eager spindle]

not to spoonfeed too much but you can look into transform.Rotate

[pastel dome]

quaternions are hard how

[rich adder]

as long as you understand, what you see inside the inspector is the rotation in euler Angles which is usually what you want to work with.. but the rotation should ideally always be kept quaternion
so any method you would do rotation = Quaternion.Euler
etc

[long jacinth]

ok thanks guys

[frank delta]

(if you have intergrated graphic card on your cpu) they will use that and not touch your 4070 or whatever else you have)

[cosmic dagger]

Yikes, good luck (understanding) . . .

[eager spindle]

you need to enable hardware accel in your browser

i think edge has it off by default

[pastel dome]

bruh like pie is just a random number its not that different than regular math

[frank delta]

it doesn't work I tried

[eager spindle]

major yabai

[frank delta]

I made all the shaders run on CPU

in one of my older project

cuz of that problem

[eager spindle]

I made a unity webgl project for one of my assignments and had to guide my lecturer on how to enable webgl after complaints that it was laggy

it ran at the full refresh rate afterwards

[eager spindle]

huh

[frank delta]

terrible idea, but it worked

[brazen ginkgo]

Can someone help me with this error? im trying to load up the 2d platform microgame

[naive pawn]

please don't crosspost

[eager spindle]

sign into unity?

[frank delta]

if you absolutely decimate your texture before using the fragment shader! everything runs kinda smooothh

[eager spindle]

idk

[pastel dome]

then again yall always tend to use cinemachine rather than figure out the camera controllers for yourselves..

[eager spindle]

the wonders of webgl, its purpose was to give computers access to your gpu to make beautiful graphics
yet you ground all your shaders to the old world

[brazen ginkgo]

I am signed in

[eager spindle]

what happens if you click revert factory settings

[frank delta]

not THAT bad

[eager spindle]

ooh

i love the graphics style a lot

[fickle plume]

You are already discussing it in #💻┃unity-talk

[frank delta]

thanks!

it got scrapped though

[brazen ginkgo]

yea sorry i hadnt gotten a response and i thought it wouldnt work in that i felt this mightve been a better spot

[eager spindle]

when multiple developers are working on a scene's UI, is it protocol to make multiple canvases? or multiple prefabs within the canvas

this is more of a survey than a help

I've been using multiple canvases until recently when one of my canvases wasn't displaying so I'm wondering how companies do it

[naive pawn]

...at the same time?

[eager spindle]

yea, one member work on dialogue the other work on objective system

[frank delta]

if at the same time, splitting them out def works better

[naive pawn]

oh well HUD vs dialogue would probably be different canvases to begin with i feel

[frank delta]

saved us from having github conflict every hour

[eager spindle]

how would one split it out though, multiple canvases or multiple prefabs within a canvas?

[naive pawn]

or at least distinct siblings

[eager spindle]

i wanna know how others do it

[naive pawn]

probably a question for #archived-game-design?

[frank delta]

since our project arent gigantic, we just make different test scenes for everyone involved

[eager spindle]

i dont understand how a project can have hundreds of developers

[frank delta]

#archived-game-design shall we?

[swift crag]

100 people are definitely not 100 times more productive than 1 person

you get diminishing returns

oh right, this moved lol

👻

[cosmic dagger]

I'd use separate canvases to limit draw calls and for each system and decouple any reference to one canvas. Makes it easier to hide/enable UI for customization . . .

[eager spindle]

using seperate canvases has optimisation benefits?

[cosmic dagger]

Yea, very much so . . .

Any GameObject or UI that updates will redraw the entire canvas . . .

[swift crag]

my ass with a MainMenu made out of one colossal canvas:

(I only have a small part of the menu activated at any given time)

so it's ok

If you have lots of UI that's all active at once, and you can chunk it up into separate canvases, you should definitely do that

[eager spindle]

thats a major problem for me because for my current project I tried to put everything in one canvas and I have an inventory

[cosmic dagger]

If you have one UI element that constantly updates, say a health graphic or value, with 30 other stationary UI elements; all of them will redraw every time the health graphic or value changes . . .

[cosmic dagger]

In general, I'd use a separate canvas for an inventory . . .

[remote osprey]

Can I have multiple SOs in the same file?

[swift crag]

No, you can't define multiple MonoBehaviour or ScriptableObject classes in one file.

[remote osprey]

Also, if I do need to separate all ym SOs in multiple files, anyone know a Visual Studio shortcut haha

[swift crag]

Unity doesn't care about the name of your class -- it cares about the file it came from

[remote osprey]

Oh ok

[rich adder]

use ctrl + . extract them into a new file

[remote osprey]

Nice, thanks!

[dense root]

What's a simple way to make the NPC face the player when they are speaking to them?

[cosmic dagger]

Use a separate file for all your classes or types. Takes the guessing out of where they are . . .

[rich adder]

dot product check which side you're on

[remote osprey]

I can finaly create events through Unity's Editor 🥺

How come my card data has no attributes in the inspector?

This is the code for CardData.cs

get; private set; are for properties. These are variables with the [SerializeField] attribute . . .

Properties do not display in the inspector unless you use an attribute . . .

You're trying to combine both . . .

[remote osprey]

Yup I need it for my game logic

1. to create Prefabs easy to modify

2. to add my game logic to it and integrate it to my architecture

[cosmic dagger]

Huh, you need which one? You have variables but are trying to use them like properties . . .

[remote osprey]

Apparently, autoproperties does not work with Scriptable Objects

So, basically, what I understood

Scriptabble Objects Attributes can't be changed at run time

Is that correct?

So I should just use them as constants

[vast sandal]

Stuff like this:
inputVector.y == 1 ? playerRigidBody.AddForce(0f, 10f, 0f) : playerRigidBody.AddForce(0f, 0f, 0f);
doesn't work because i check an vector value?
Or because I try to call a function in the consequence?

[remote osprey]

Ok, I think I get it now.

[eternal needle]

Have u read the docs on ternary? https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/conditional-operator

evaluates a Boolean expression and returns the result of one of the two expressions,

[vast sandal]

Glossed over it... but didn't get it

Ah I see your explanation does wonders 🙂
Kinda thought its just a "shorter" if statement, but its actually allways giving a return right?

[swift crag]

The core problem is that, if you write an expression as a statement (basically, as a line of code), it must be one of:

assignment, call, increment, decrement, await, and new object expressions

The conditional operator is none of these.

I'm not sure of the exact justification for that rule.

In Java, for example, I'm pretty sure you can freely write stuff like:

3;

C# does not permit this

I suppose the point is that, in most situations, there's no point to writing an expression like that, so it must have been a mistake by the programmer

[eternal needle]

No explanation here was mine. I copy and pasted exactly from the docs
Yes it always returns the value

[cosmic dagger]

was afk. you can display auto properties in the inspector; you need to use the correct attribute . . .

[swift crag]

this has nothing to do with being a scriptable object, mind you

it's entirely about how Unity serialization works -- which is the same for any unity object

[cosmic dagger]

you can change/mutate an SOs value, but you should not because any other object (class) with a reference to it, will have (point to) those changes . . .

[cosmic dagger]

properties, variables (fields), and methods are the same for all types. it's not specific to SOs or any particular class . . .

[vast sandal]

Yeah Visual Studio prompted me with the same thing.. but isn't addforce() a call?

[swift crag]

Sure, it is

The entire conditional operator expression is not.

[remote osprey]

What I wanted to do was use my scriptable object instancees like any other class

[swift crag]

What you've written is, in the eyes of the compiler, no different from:

true ? 1 : 2;

[remote osprey]

which is why i made everything with auto properties, to consider SOLID, basically

[swift crag]

(although, AddForce returns void, so there's no real way to write an identical expression without function calls)

[remote osprey]

I don't want to alter my SO objects outside of runtime, what I want to do is instantiate copies of them in code and modify those instead

[vast sandal]

Yeah I see.

[cosmic dagger]

[field: SerializeField] is the attribute to display properties in the inspector. also, properties should be PascalCase, and your GetHealth method is unnecessary because that's what your Health property should already do. it's read-only . . .

[remote osprey]

Oh GetHealth exists for IDamageable interface

Otherwise I would've tossed it

[cosmic dagger]

that defeats the purpose of an SO. just create a regular C# class: POCO, and declare a variable of that class in your SO. then you can copy that C# class and mutate its values without affecting the original SO . . .

[remote osprey]

Wouldn't it be easier if SO let me do that tho

I wouldn't have to create another class

[swift crag]

it doesn't defeat the purpose

the scriptable object contains the data

[eternal needle]

You can create instances of SO but you should dive a little deeper into the problems with doing so before actually doing it

[remote osprey]

Ok xD

[cosmic dagger]

basically, the SO_CardData SO is a wrapper for CardData C# class . . .

[remote osprey]

So apparently SOs hates interfaces 🙂

[remote osprey]

this is probably the "right", performance efficient way

But i'm just gonna go with my way because it's one less class babbyyy

Creating a new C# script has started becoming my most hated activity lately 🙂

[stuck palm]

can unity serialise a list of a list?

[carmine sierra]

is it not convention to make public variables capitalised

[cosmic dagger]

🤔 it takes 5-10 secs . . .

[remote osprey]

Exactly 🙂

5-10 secs to add a potential bomb to my code database 😄

jokes aside

I'll just choose the minimum amount of classes to keep the code more maintainable

being a solo dev has been literally hell 🙂

[eternal needle]

By that logic, have your entire game in 1 class. Need to fix anything, its only a change to 1 file!

[remote osprey]

Thing is, why add one more class when I could just use my SO class to hold the same data and have the same behaviour haha

It makes no sense

[eternal needle]

Line 3 is c# convention, although not sure if unity differs. Could either be some unity specific thing or the quiz might just be wrong

[stuck palm]

public struct ReplayPlayer
{
    public CharacterEnum character;
    public int characterColor;
    public int characterID;
    public List<List<ButtonState>> _buttonRecording;
    public List<List<MoveState>> moveRecords;
    [NonSerialized] public PlayerInputController inputController;
    public bool isReplay;
}

is there a way to make the nonserialized thing show up in the inspector? i have it as [nonserialized] so the json convert doesnt try to serialise it, but i need to be able to see it in the inspector

[eternal needle]

Then you should look the downsides of SO, especially if you're creating instances at runtime. I said the same above somewhere, it's not as simple.

[stuck palm]

nvm i found a fix

[remote osprey]

Do you have any resources so I can look into this?

I'm literally creating SOs all the time in my game lmao

I designed it so that each action is an SO

[eternal needle]

Can you still see it in debug mode? Usually I would create classes specific to what I wanna save so I dont have this issue

[eternal needle]

Not aware of any that goes too deep into it, but theres a difference of creating an asset in editor time and creating an instance at runtime. The most commonly brought up issue is that changes dont persist to these, and may reset back to it's original state if it's not referenced anymore in a scene. If you're creating instances, you also need to manually destroy them. It's not hard, just a pain compared to using plain c# classes, because the GC handles this for u

[remote osprey]

Oh, I see

This seems pretty important info

How do I destroy a SO instance?

[stuck palm]

i just replaced [nonserializable] with [jsonignore] which achieves the same thing for me

[eternal needle]

the same way you destroy any unity object

[peak chasm]

*eye Twitch ok im stumped here. Iv got a Sav Data script and It MAKES the files, so hurray for that, and the Inventory Section works perfectly fine, but The Player World Location part does not. Im TRYing to make it so while the update loops run Player POS updates in realtime. Player Object POS does, and I'm trying to feed that data into the other variable, but it doesnt work. I cannot figure out why, is there something really stupid about [System.Serializable] ??? When i press load all the Vector3 variable stay at 0 so saving player pos is getting hard

[lavish magnet]

I have this on all my zombies, its my function for them attacking, This if statement seems to always go through. player is the player gameobject, that the zombies target, why does this if statement go through if the prints are equal

[peak chasm]

I have NO idea what im doing wrong, this is my first time actually trying to play with JSON and i just dont get it

[cosmic dagger]

i agree, a public variable should be capitalized to signify its intended use when looking at a class' members using dot notation . . .

[stuck palm]

private void FixedUpdate()
    {
        if (!started) {return;}
        foreach (ReplayPlayer rep in _replay._replayPlayers)
        {
            rep._buttonRecording.Add(rep.inputController.buttonList);
            rep.moveRecords.Add(rep.inputController.moveList);
            print("Added " + PrintList(rep.inputController.buttonList) + "to buttonlist");
            print("Added " + PrintList(rep.inputController.moveList) + "to movelist");
            rep.frameLength++;
            rep.lastMove = rep.inputController.moveList;
            rep.lastButton = rep.inputController.buttonList;
        }
    }

I'm getting proper console logs, but when I actually go to check the Json, it doesnt actually add them to the list. why is this?

[teal viper]

Well, I don't see you doing anything with a json in this code.
You'll need to provide more details. What the heck is ReplayPlayer, _replay and _replay._replayPlayers? And why are you accessing fields that should be private according to their naming convention?

[stuck palm]

Yeah my naming conventions are abysmal honestly. I've just decided to call it a night for now so I'll ask this question again tomorrow cus I don't have the project open anymore

It will probably come to me as I sleep

[remote osprey]

should i make everything inside an object null before Destroy()ing it?

[teal viper]

No

[remote osprey]

I saw in a video that Unity doesn't necessarily deallocate memory after Destroy() though

And that references to it should be null

However, my thinking is that if I destroy() an object all of its properties/fields will be destroyed as well, correct?

Hey guys, so I have been trying to detect a side switch (meaning detecting if the player has went from left to right and vice versa) by comparing the current position and the previous position . the problem that I am having here is that the if statement that checks if the player has side switched always returns false and thus it never executes the side switch. Here is an example of my code:

    void Update(){
        CurrentHorizontalPos = transform.position.x;
        PreviousHorizontalPos = CurrentHorizontalPos;
        Debug.Log(hasSwitchedSides); //Always returns false and not true in all cases
    }    
    private void EnabledSideSwitch(){
        if(PreviousHorizontalPos != CurrentHorizontalPos) hasSwitchedSides = true;
        else hasSwitchedSides = false;
    }

What could be the issue here?

[cosmic dagger]

when a unity object is destroyed, any (of its) components on that object will be destroyed along with it . . .

[summer stump]

Properties and fields don't exist outside of objects in c#
(Object being distinct from GameObject)

So yes, if you destroy the object, all of its member fields and properties will be destroyed as well

[slender nymph]

technically they wouldn't be destroyed at all since c# does not really have the concept of destroy. Once nothing else references that object and it gets GC'd then anything only referenced by that object will also get GC'd

[remote osprey]

So I don't need to set them to null before destroying the object, right?

[cosmic dagger]

it's a bit complicated. when you call Destroy, the object is marked for destruction, but that doesn't happen until the end of the frame

other references to that object will not set to null, so checking for null will return false because the reference is not null (even though the object is destroyed). what you should do is assign the object to null after calling Destroy on it . . .

[remote osprey]

Oh ok

Thanks for the explanation!

Are you people really thorough when it comes to memory handling?

[teal viper]

Not unless it's an issue. At which point you'll use the memory profiler to optimize it correctly.

Most of your memory consumption is gonna be from texture and mesh data anyway

[remote osprey]

public class Board : MonoBehaviour, IDestroyable
{
    public static Board Instance;

    public List<LinkedList<Canvas>> summons { get; private set; }

...
    public void ClearDataAndDestroyInstance()
    {
        foreach (int i in Enumerable.Range(0,summons.Count-1))
        {
            foreach (Canvas canvas in summons[i])
            {
                Destroy(canvas);
            }
            summons[i] = null;
        }
        summons.Clear();
        summons = null;
        Destroy(Instance);
    }

Is something like this too much?

[remote osprey]

I get trauma from programming in C in college

Now I'm implementing my IDestroyable on every class in my project hahaha

[teal viper]

C doesn't have a garbage collector, so you need to manage memory manually. C# and unity does, so you just need to be aware of GC rules.

[teal viper]

This sounds like an unnecessary overhead

[eternal needle]

you surely dont need to set every index to null, call .Clear() AND set it to null.
Honestly dont think you need to do any of this. Its pretty sufficient to just check for null before doing what you want.

[teal viper]

This also looks like an unnecessary overhead to me.

[remote osprey]

Ok

I guess I'm only gonna be careful when around my instantiated SOs

Making sure to delete ALLL of them when my game session is over

[eternal needle]

you really dont need to instantiate SOs. You're doing this because you dont want to simply make another class and let the GC handle this for you

[remote osprey]

but what's the problem with this tho

I googgled it and ppl only told me to be careful with destroying my SOs

[eternal needle]

now you're in uncharted territory because you dont understand some downsides to it. This is just gonna take you longer than the 1 minute of setting up another class. Like "the game session is over" why does it matter what you do with your instantiated data

[remote osprey]

I dunno, It just feels right to code like this

Everything has been an uncharted territory so far

I'm just doing my best to manage my anxiety

[eternal needle]

a common mistake beginners somehow think is things are better because there is less code. Consider that this couldve been all avoided if you decided against instantiating SO's. And you wouldve already been coding another feature

just a note, when the game ends, everything is destroyed. its not just dangling around in memory if you dont destroy it past the lifetime of the application

[remote osprey]

What feels wrong to me is not that there will be more code, is that the extra class will be (almost) exactly the same to the SO

This terrifies me of the amount of times I'll confuse the two classes
