It's about size, not length

[cedar bone]

yeah im aware

[teal viper]

You can compress or make lower res video longer

[willow scroll]

51.2MB. You won't be able to send it even with Nitro

[cedar bone]

any tools to compress?

[willow scroll]

Your dimensions are 3360x2100

[teal viper]

Yeah, the main issue is the crazy resolution

if you record with OBS, you can control the video resolution

[willow scroll]

Yes, google "compress video" and click on the 1st site: https://www.freeconvert.com/video-compressor

[cedar bone]

thank u!

[crisp token]

sorry, I don't understand what saving the value has to do with

[willow scroll]

Hold on, I'm thinking about the example

public class Animal { }

public class Dog : Animal
{
    public int noIdea;
}

In this case, you can create a Animal as a Dog:

Animal animal = new Dog();

This is an Animal now, but you can freely convert back to a Dog and its values will be saved:

if (animal is Dog dog)
    // ...

[median halo]

RaycastHit2D hit = Physics2D.Raycast(transform.position, -Vector2.up, 1.0f, grNd); anything wrong with this? it isnt working

[willow scroll]

Maybe, a better example would be with a constructor

public class Dog : Animal
{
    public int noIdea;

    public Dog(int noIdea)
    {
        this.noIdea = noIdea;
    }
}

[crisp token]

I understand downcasting and upcasting for the most part

[willow scroll]

if (animal is Dog dog)
    dog.noIdea // the chosen value

[willow scroll]

The same goes for enum and object

Everything can be casted to object

And its actual type will be derived from it

[crisp token]

so when I assign the object into the object list, which holds certain enum types, the object being assigned is automatically casted to the enum Type if possible?

[willow scroll]

The object is not implicitly casted to enum

Everything can be explicitly casted to object by either using (YourType)@object or @object as YourType

[crisp token]

that would make sense, but for some reason chat gpt (which ik is not 100% correct) says it would be

[willow scroll]

You are free to choose ChatGPT's answer over mine

[crisp token]

lmao no no, thats not what i mean

[teal viper]

It's also possible that you're misinterpreting it's answer or it misinterpreting your question.

[crisp token]

What i think ChatGPT said is because the Enum.Parse method goes like this: Enum.Parse(Enum Type, string, bool), it takes the Enum Type you put in and uses that

but it returns an object because Enum is a special class or something

[teal viper]

To be fair, I don't understand what the question is either. It feels like the conversation is going in meaningless circles.

[crisp token]

once i can test this thing out, and if it works, ill ask the question again

no use trying to solve an equation with two unknowns

[teal viper]

There is actually a type safe parse method, that I would use if I wanted to parse an enum. Instead the ones that return an object.
https://learn.microsoft.com/en-us/dotnet/api/system.enum.parse?view=net-8.0#system-enum-parse-1(system-string-system-boolean)

[crisp token]

im trying to understand the api but its going over my head

[teal viper]

What part of it?

[topaz mortar]

Not sure if coding question, but doesn't seem to belong anywhere else either.
How do I make my bunnies go up/down a little bit, so they don't all overlap exactly?

[crisp token]

I think i got it, only cause I already know what its supposed to do

[topaz mortar]

Would it be a bad idea to just disable gravity for monsters? I don't think I will ever use it in my game

Or can you disable gravity for the entire game somehow?

[vernal bone]

i mean, you can set random height when you set their destination position.

or spawn them at random height, if it's not critical for your gameplay

[topaz mortar]

but then gravity just pulls them down again (I disabled gravity and did it like that)

[vernal bone]

why gravity will pull them down if it is disabled?

[topaz mortar]

no it works now, just not sure if disabling gravity like that is a good idea

[vernal bone]

don't see why not tbf, but i'm not that proficient in unity for now.

you can look into charactercontroller i guess, but i never touched that

[severe forge]

Could anyone guide me as to what could be happening here? When I create a host after the first time, I'm getting duplicate connection calls of my own client.

I'm using relay to create a host

[topaz mortar]

Why is this not hitting? The Transform y is set to -3.2
When I set it to -3.4 it does hit

RaycastHit2D hit = Physics2D.Raycast(transform.position, direction, range, layerMask);
Debug.DrawRay(startPosition, direction * range, Color.red);```

ew my raycast doesn't use startPosition oopsie

[warm raptor]

Why would it be laggy ?!

[meager gust]

because json is slow. it's all string based internally.

you'll also be generating loads of garbage that needs to be cleaned up

[warm raptor]

Oh nice I dont use json 😆

[warm raptor]

Also few days ago everyone here told me that what I was doing was Bad and that I should use Json

[cedar bone]

Can someone help me out here? #✨┃vfx-and-particles message

[eternal needle]

well yes, because it was better than what you were trying to do. You were manually sending the variable names and the data, then also parsing it manually.

[eternal needle]

dont crosspost #📖┃code-of-conduct

[cedar bone]

yeah ik I shouldnt, but no one every checks that channel

but yeah ur right

mb

[warm raptor]

Ok, but if parsing manually is bad and Json is bad , what is the good way of sending data ?

[meager gust]

what do you mean parsing manually?

can you show me an example

[warm raptor]

Give me 5 minutes I lunch my computer

[eternal needle]

again, you don't want to use strings when serializing real time data for video games.

[meager gust]

you're causing future you a lot of issues that you're going to need to clean up in the future. this also will not scale at all as player count increases

at the very least just serialize raw binary data. like pointer cast your values into a byte* and memcpy that into your buffer or something

[teal viper]

Often you'll just reinterpret the bytes with an offset. No strings involved whatsoever.

[meager gust]

ideally you'll want something automated, so you're not doing all of this by hand and creating human error...

you'll generally not want to create any heap garbage at all for network messages

[cedar bone]

Perlin noise go brrr

[warm raptor]

I'm sry but I don't really understand what you mean ( because m'y english is not the best) , because with my Websocket I'm obliged to send my messages in the form of a string

[meager gust]

you can't send a byte array?

[warm raptor]

what's that ?

like just 0 and 1 ?

[meager gust]

no

you should probably do some research into this if you're dead set on writing your own network code...

or just use one of the pre-exising network libraries like mirror

[teal viper]

Your networking api should probably at the very least be able to send it as char arrays, which is basically the same as a byte array

[warm raptor]

I already try, but I can't find any usefull stuff, I have been working on multiplayer for more than 1 year now and I never find anything usefull, moreover the librarie I'm using doesn't have a lot of documentation

[eternal needle]

so you see now why literally everyone has told you what you're doing wont work? and that we arent waiting to be proven wrong

[meager gust]

I can assure you that using mirror is much simpler than writing your own netcode API

a middle schooler could figure out mirror

[teal viper]

Yeah, I'd avoid implementing your own solution if you don't even know what bytes are

[warm raptor]

I know but I already make a test game using this method, and even with 6 player it was working perfecly fine

[meager gust]

if thats how you want to do it, then nobodies going to stop you. I'm just warning you that it's a waste of time for anything remotely serious

[teal viper]

Well, if it works good enough for you, then what is the question?

[warm raptor]

because everyone is telling me that my way of doing is bad (and I'm sure you're right) but I make some test and It seams to work so I'm very confused

[meager gust]

try spawning in 40 networked objects all being serialized and deserialized 30 times per second with your string method

your performance will tank. I guarantee it.

[teal viper]

It depends on your setup. If you profile properly, you might see that this code eats quite a bit of your frame time.

Which basically leaves less budget for other features in your game.

[meager gust]

among other things, your method also doesn't factor in interpolation. so you'll need to be sending packets at the monitor's refresh rate for it to appear smooth

it also uses TCP which uses head of line blocking... which will cause visual jitter and freezing when packet loss occurs as packet transmission will completely halt until all of the missing packets are resent and ACK'd

unfortunately multiplayer isn't as simple as just sending data back and forth.

[warm raptor]

that why it's a bit laggy some time 😅

[warm raptor]

I feel so bad now, it's been over 1 year that I've been trying to learn how to make my multiplayer and I can't find anything or anyone to explain to me the right way to do it, and now that I'm almost done everyone's coming to explain to me that everything I've been doing all this time is just crap ...

if you truly want to learn netcode, those links will give you an introduction
you're missing a lot of basic pre-requisites though, like understanding what a byte array is... you need a lot of work in other areas

https://mirror-networking.com/

or just use mirror like a sane person.

[teal viper]

For starters, if your game works, don't let anyone discourage you. Your solution might be just good enough for your use case.

That being said, that's the price you pay when you jump into a complex project(like one that requires multiplayer), without proper learning or experience before that.

I'm sure you've been told not to start with a multiplayer project when you first started learning gamedev or unity and you probably ignored these warnings.

[warm raptor]

you're right, everyone advised me against making a multiplayer by myself, but I know insinde of me that if I'd never made one, I'd never have continued developing video games, so even if my project is far from perfect and the most optimized, it's still allowed me to learn a gigantic amount of information, it's very far from being my first programming project, but it's the one that's really going to allow me to say that I'm into programming.

that's said I'm gonna learn what's a byte array, thx for your help !

[meager gust]

like dlich said: if your way works, you can keep doing it that way

my comments are merely suggestions.

[warm raptor]

your right, but finding out if I can improve my code can only be a good thing.

[warm raptor]

I actually think I know what you're talking about since I took 1 year of computer science in high school last year, it's just that talking about a subject I'm not an expert in, and in English to boot, doesn't really help me. 😅

[eternal needle]

imo, if you dont have a concrete plan for the game so far then you should heavily reconsider this whole sunk cost. A concrete plan meaning stuff like how many players you want to support, the actual gameplay planned out, and really just the overall architecture. You're gonna either have to rewrite this system or settle for what you have with the issues that were pointed out above.
I even tried first making a multiplayer game. i rewrote systems so many times, which all was useless because i realized a new feature would require changes. I chose to abandon it to make a singleplayer game and i have around 9 years experience in CS.

[meager gust]

yes, the whole string parsing stuff is just a fraction of the issue here.
manually serializing the data will slow production down to a crawl, especially when you start wanting to change things and now you're wondering why your data is coming in corrupted (because of human error 😉 )

[eternal needle]

It could even be a nice project just for friends to see, but remember that projects have to end eventually. If you aim to upload the game to steam, and it has any lag issues, everyone is refunding it.

[warm raptor]

that true, that why I want to make the best thing possible, I don't want to scam people

[meager gust]

@warm raptor
https://mirror-networking.gitbook.io/docs/manual/guides/synchronization/syncvars

{
    [SyncVar]
    public int health = 100;
...```
this is how modern netcode frameworks will synchronize variables, for example.

you just tag it with an attribute, and it does everything automatically. synchronizing the state should be as simple as possible during actual game development. you shouldn't be trying to write a netcode framework and a game at the same time. if that makes sense. you should be building your game on top of an already existing netcode platform either created by you or someone else.

I just called the bot once wdym if you helped instead of being such a discord mod nerd

[meager gust]

lol

wrong answer

[fickle plume]

@lunar lark Help with what. You didn't ask any question yet.

[lunar lark]

So I've made an ingame saving system like the one in hollowknight but Im having trouble with something. My enemies despawn when you enter and that's alright until you want to get out the save point, I want the enemies to respawn after exiting the save point but it doesnt. Sorry for bad englsh.

CLASS1 Enemic:

public void PlayerEnterAltar()
{
Enemic[] enemies = FindObjectsOfType<Enemic>();
foreach (Enemic enemy in enemies)
{
enemy.MortSLS = false;
enemy.IsDead = false;
enemy.CurrentMoveSpeed = enemy.moveSpeed; // Guarda la velocitat actual
enemy.moveSpeed = 0f;
enemy.gameObject.SetActive(false);
}
}

public void PlayerExitAltar ()
{
Debug.Log("Enemics tornen a apareixer");
Enemic[] enemies = FindObjectsOfType<Enemic>();
foreach (Enemic enemy in enemies)

enemy.gameObject.SetActive(true);
enemy.MortSLS = false;
enemy.currentHealth = enemy.maxHealth;
enemy.moveSpeed = enemy.CurrentMoveSpeed;
}

@lunar lark Again. Read the #854851968446365696 on how to ask question properly and post code,

[lunar lark]

Why all these rules

[warm raptor]

I understand you, but that's not the way I want to do it, I understand that modern networking may be easier to work with, but my networking litteraly does the same thing, I know that for you I might doing my networking the wrong way, but I didn't want to make a P2P game, I really wanted to work with a server

[meager gust]

because its annoying to read unformatted code like that

[lunar lark]

womp womp

[meager gust]

I'm not talking about p2p, but that's okay. you can do it however you like 🙂

[fickle plume]

!mute 731473620949532704 1d I guess try again next time properly instead of wasting people's time.

[eternal falcon]

martiiic was muted.

[warm raptor]

Oh I might miss understand but what I wanted to Say is that I'm still young and I might not make game my whole life so I think that it's better to learn how to make networking from scratch instead of using things that already exist because it would allow me to use this knowledge other where than juste in Unity game, and I think that this is the kind of things that might help me find a job later

[eager spindle]

in the real world you build a REST API as your server backend so you can get information from the server.
E.g. for those apps that track stock markets you can then send a GET request getting the latest financial data

alternatively if you absolutely want to learn networking for games without making a game see https://emily-elim04.medium.com/building-real-time-apps-using-websockets-dc137ccdd34b

[warm raptor]

Thanks, I don't understand it all but it's still quite interesting!

[teal viper]

Well, you can both use an existing library and learn how to do it from scratch, by learning how the library works. Especially if it's an open source one. Instead of trying random unoptimal things.

When you have proper understanding of the underlying systems, you can implement your own.

[warm raptor]

that true, but I make my choice I already buy a vps and I think the way I'm doing will work perfectly fine for the numbers of players their will be in each game 🙂

and I will have time to improve, this is only my 2 project with my homemade networking

[teal viper]

I don't see why having a server prevents you from using a library

[eager spindle]

you did not need to buy a vps but wtv

you can test on your own pc or use AWS free tier

[teal viper]

you would need a server regardless of whether you use a library or not

[warm raptor]

but I don't understand what your "librarie" are , Networking librarie aren't just P2P ?

[teal viper]

No..?

They're frameworks for networking. Most of them support a wide range of networking styles, including p2p and server based.

It's just that some of the companies that provide them also happen to provide hosting services.

That just shows how little effort you put into researching the topic

[warm raptor]

or just I start programming a bit more than 2 years ago and was completely loss ?

[teal viper]

That's why you research first. To not get lost

And yes, it's a very complex topic, which is why no one recommends you start with it as a beginner

Here's mirror explaining different hosting solutions btw, including a dedicated server:
https://mirror-networking.gitbook.io/docs/hosting/pragmatic-hosting-guide#id-3.-dedicated-servers

[tender wharf]

Any clue on why the signal isn't running GameController.StartRace()?

[half egret]

You need to emit the signal in the timeline

Oh hrm

Is "CinematicEnd" an inbuilt signal or one you made?

[tender wharf]

I made it

[half egret]

You need a signal emitter track IIRC in the timeline

And then move it to the end of the timeline

e.g.

[tender wharf]

yeah, I've got you

[warm raptor]

I don't know why, instead of helping me, people just keep telling me that I won't make it on my own... Anyway, it doesn't matter, I've always been alone and I've always managed on my own, so with enough hard work, I'll eventually get there. I know they say there's no point in reinventing the wheel, but honestly, maybe what I'm doing is garbage, unoptimized, ugly, and burns your eyes when you look at my code. But I know that doing things by myself is the only thing that motivates me. I know you think I'm stupid and that I should refer to existing libraries, but I know that's not what I enjoy. If we want to have a good game in the end, the most important thing is to have enjoyed the work we've done. I have my own way of working that people often don't like because they think it's not clean enough or professional enough, sure, but unlike others, I see my projects through to the end and refine and rework them until they're good. My network might not be perfect, but at least I can connect players to different games based on the ID they enter, make sure they can move around and others can see the animations they make, ensure the character can shoot and everyone can see the shots, allow players to switch teams and everyone to access the list of different teams, and let players shoot and kill other players while my server detects who killed whom. I've also made 90% of the models myself, including the characters and their animations. I might be a lousy beginner, but at least I have a functional project that's making progress!

[teal viper]

As I said, I'm not trying to discourage you or anything. It just seems like you had some misconceptions about networking libraries and networking in general. I was just trying to show you clarify these misunderstandings.

[warm raptor]

I know, but I'm really sad to see that I've work 1 year to see that everyone is telling that what I've done is trash 😟

[timber comet]

Yeah, everyone got there once in their life

[tender wharf]

imagine you get someone to help you with your game and they see this

sure it works for you but how do you expect them to work with this

[teal viper]

Well, what do you expect us to say? Good job on lack of research?
You're asking in a beginner channel. Obviously everyone would try to point out things that you might be doing wrong.

[ionic zephyr]

How can I make a system in which objects receive more or less damage depending on the weapon/tool you are holding? is it with Enums???

[vital tangle]

Hello

[teal viper]

You could just pass the damage value of the weapon when dealing damage.

[ionic zephyr]

yeah but I dont want an axe to deal the same damage to a tree as a sword for example

[vital tangle]

I wrote this class in C++

it uses invoked System class from C# to call the binary reader and writer

I am going to do a native call to the methods from my unity C# code

here is the source code

#include <string.h>
#include <msclr\marshal_cppstd.h>
#include "VM.h"

using namespace msclr::interop;

VM::VM(System::IO::BinaryWriter^ writer, System::IO::BinaryReader^ reader)
{
    VM::reader = reader;

    VM::writer = writer;
};

void VM::Shift_Half_Unsigned_Address_F()
{
    System::UInt16 EF = VM::reader->ReadUInt16() * 32;

    System::UInt16 EB = VM::reader->ReadUInt16() * 30;

    VM::writer->Write(EB);
    VM::writer->Write(EF);
};

void VM::Shift_Half_Unsigned_Address_B() 
{
    System::UInt16 EF = VM::reader->ReadUInt16() / 30;

    System::UInt16 EB = VM::reader->ReadUInt16() / 32;

    VM::writer->Write(EB);
    VM::writer->Write(EF);
};```

my question is how to create the bindings for it?

[teal viper]

You could have different types of damage or different modifiers depending on the target. Or have the target have different damage reduction stats against different types of damage. There are many ways to go about it. It depends a lot on your project needs.

[ionic zephyr]

Okay, Ill guess Ill go with that, thanks!

[vital tangle]

any helps?

[teal viper]

1. I don't see why you need it to be in C++..? You can do the same thing in C#.
2. If you really want to do it, you'll need your class compiled into a dll. And imported in C# using PInvoke.
   https://learn.microsoft.com/en-us/dotnet/standard/native-interop/pinvoke

[vital tangle]

yes i am compiling it in dll before using

i just dont know if it will work or not

[teal viper]

Well, there's a 100% sure way to tell: try it and see.

[vital tangle]

[ember gate]

when doing a platformer and creating the world with a tilemap what for example if I wanna make some moving platforms but the platform itself may consist of more than one sprite how can I make it so the code can fit to most type of platforms?

[deft grail]

dont use a tilemap for stuff like that i guess

[ember gate]

so like should I combine tilemaps with stuff like normal sprites u mean?

[deep yew]

I'm trying ot unfreeze these caps but they keep falling off due to rigidbody.
Is there a way to freeze the rigidbody until a button is pressed?

[deft grail]

like you make your normal level with tilemap, then make moving platforms and stuff without a tilemap

[deft grail]

yeah you can freeze it, check the docs for rigidbody

[deep yew]

When a button is pressed, not perm freezed

[deft grail]

you can change them through code

[deep yew]

I'll check rn

[tender wharf]

if its in the ui there must be a way to do it programatically

[ember gate]

oh ok and like when positioning it is there a way to position it without moving it freely and move for example some pixels in a direction everytime I move it in the editor?

[deft grail]

like snap to grid type thing? hold ctrl i think or one of them buttons i forgot and it will snap

[ember gate]

oh ye

nice thanks

[deep yew]

Couldn't find any in the rigidbody doc

[deft grail]

https://docs.unity3d.com/ScriptReference/Rigidbody-freezeRotation.html

[half egret]

[half egret]

For position specifically

[deft grail]

https://docs.unity3d.com/ScriptReference/Rigidbody-constraints.html

[ember gate]

is there a way of seeing the trajectory of on which the platform is moving from point A to point B

should that be done with raytracing or something like that?

[ionic zephyr]

Should the weapon that my character carries be a ChildObjectof the player?

[deep yew]

Still wont work since I'm staring them in arrays
I'll try to figure it out somehow

[deft grail]

yeah

[deft grail]

huh? what wont work why, what difference does that make

[deep yew]

Just gives me an error

[deft grail]

well if you want help, you need to show the code and error

[ionic zephyr]

and should it have its own component to choose what weapon it is using each time?

[deft grail]

you can make like a weapon holder child object, that have a script and then activate/deactivate what weapons you need

[ionic zephyr]

Okay, that makes sense

thanks

[deep yew]

Now it doesn't
thanks

[ionic zephyr]

Attacking with weapons should be done with triggers? or is it better to do with OverlapCircle

[deft grail]

overlapcircle

[ionic zephyr]

area?

or all

[deft grail]

all i think

[ionic zephyr]

thanks a lot

[warm raptor]

I just looked up what a char array is, and I don't understand how it would be more efficient than a string. In both cases, I would need to retrieve the information I need using indices, and anyway, I don't need to be able to modify the messages I receive or send. Can you explain, because I don't really understand the usefulness of a char array.

[burnt vapor]

Is the whole point sending data over a network to clients?

You don't send stuff as strings then

The reason why JSON is bad is because you bloat up your packets way more than what they need to be and this is horrible when you send inputs and stuff to the server for example. It also requires serialization/deserialization

So if this is some multiplayer game that uses networking, then look into BinaryWriter and BinaryReader

Alternatively make your own packet class that reads/writes from a buffer. It's not a lot of work

I never heard something requiring strings specifically so I doubt that's needed here either

[warm raptor]

i'm not using JSON, I'm just sending String, but they told me that char array could be a better solution, but I will still look at what you sent me 😁

[teal viper]

Actually, char array was a mistake. I was confusing with C++ where a char is 1 byte. In C# a char is 2 bytes, so you can't use them interchangeably. That's why I'd suggest to look at how some of the networking libraries implement it in C#.

[half egret]

Weird that a char is 2 bytes in C#, I've done networking in C using chars. I wonder what that extra byte is used for... can't possibly be a null terminator. I'll have to look at the docs

[languid spire]

it's because chars and strings in C# are utf-16

[half egret]

ah.. right

thanks!

[ionic zephyr]

How can I mantain cohesion with my attack component and make sure that I can access the same method "Attack" but it has different effects, for example, I want my enemies to attack with their own attack stat, but I want my player to attack depending on the weapon it has?????????

So over the years I've learnt some stuff what to do and not to do, as well as the fact you should always keep your code organized.
I have created this script, which I copy and paste into new scripts and edit only the stuff I need, so that everything is organized the same.
What do you think about this and how did I do?

https://paste.myst.rs/kxsnexoc

[burnt vapor]

Right, but what is the goal here? Is it a networking solution like I assume it to be?

Sending data to clients etc

There are different patterns depending on how you are communicating, but if it's networking where a game needs to continuously send data, then you should use sockets and a system that sends/retrieves byte arrays basically.

JSON is still valid if the data you send is not continuous and might have a large/dynamic size.

[warm raptor]

yes I'm making a websocket serveur for my fps

[burnt vapor]

Yeah, then just make a Packet class that creates a byte array and send those instead

[warm raptor]

ok, but why I need to use a byte array instead of just sending a string like i'm already doing ?

[burnt vapor]

Because you will have a string of varying data which must then be parsed into usable data

It's slow and bloaty

You also have no control over the actual size, so you can't specify single bit data since everything needs enough bits to fit in a whole character, which is a waste of space

[teal viper]

It's not just about sending(although it's definitely better to send less data than more without need), but also about processing that data on the sending and receiving ends.
At the moment you have issues with all of these things.

[ionic zephyr]

How can I mantain cohesion with my attack component and make sure that I can access the same method "Attack" but it has different effects, for example, I want my enemies to attack with their own attack stat, but I want my player to attack depending on the weapon it has? Basically what I need is something that makes the player or any entity attack but in different ways

[burnt vapor]

It also depends a lot on encoding but regartless you are wasting time converting the string into usable data, which is the worst part of it

Something that is negligible at the start but very noticeable once your game ramps up on the data is sends/retrieves

The socket class and its derived classes also don't allow strings in general, only byte arrays 😛

[willow scroll]

I first thought it was a class, which you derive from to expand your other class' functionalities, but it does not seem this way.
I understand what you are trying to achive, but I do think it's pretty useless. If I created a script in Unity, and this was its code by default, I would simply remove everything inside of its scope, the same way I do it with Unity's default Start and Update methods on new script creation, along with its descriptions

[hot palm]

Can I replace the default script stuff?

[willow scroll]

But this is merely my opinion, and there is definitely nothing wrong in you using this, as long it speeds up your work. This is something, which is used by you, and you shouldn't be asking others' opinion, because there is nothing to correct, if we're talking about syntax or errors

[warm raptor]

So my string is converted into something to be send and then this thing is converted back to a string , but a char array won't be converted ?

[burnt vapor]

A char array is a bloated byte array

They are a bunch of numbers

I don't see why you would be using a string here, why are you so fixated on using it?
Another point, using a string will cause culture issues if you use characters of varying culture.

[hot palm]

Doesn't speed it up necessarily, but adds a lot of organization imo. I just know where specific methods would be even after a month of not looking into it for example. Or others looking at the code know what to expect where, if they've looked at the mask once

[warm raptor]

I'm a beginner and to be honest I have no real idea what happens once my code is compiled😅

[warm raptor]

ok , so let's assume that I'm now using a char array instead of a string, how could I get the information I need from the char array ? because now I'm just parsing my string

[burnt vapor]

So how are you sending data over the newtwork to begin with? Surely you'd have to use a byte array in general?

I don't think sockets accept char arrays since they are still different

[burnt vapor]

I don't think you should have anything regarding char arrays or strings in your code

Please give an example of data currently being send in your game. What is that exactly?

[willow scroll]

Yes.

C:\Program Files\Unity\Hub\Editor\2021.3.27f1\Editor\Data\Resources\ScriptTemplates

Go to this location and add the suitable code to this file:

81-C# Script-NewBehaviourScript.cs.txt

Note that the location can differ on your device and Unity's version. See more here

[hot palm]

Thanks, I found it!

[half egret]

Here's the example they initially presented
#💻┃code-beginner message

[burnt vapor]

I have no idea what is happening in that code

Does it generate a string full of key-value pairs?

Is it just sending a lot of booleans?

[willow scroll]

Additionally,

How to have only one public static "Instance" at a time, while one game object should never have 2 "Instance"s as components
You have to search for "unity singleton" on the web and copypaste the generic Singleton to your project, which you then derive the suitable classes from

So remove the functionality from your Awake method

[warm raptor]

so first i create a Websocket in my client

private void InitializeWebSocket()
    {
        ws = new WebSocket("ws://127.0.0.1:8000/Lobby");
        ws.OnMessage += (sender, e) =>
        {
            message = e.Data;
            messageQueue.Enqueue(message);
        };
        ws.Connect();
    }

then I can just make to send the data

ws.Send("my message as a string")

[hot palm]

Ohh okay, I thought my singletons were a bit weird

[willow scroll]

I also feel like you don't need all those comments, because you should definitely know what they mean yourself

[burnt vapor]

Are you making a web game?

In the browser?

[hot palm]

Yeah this was created for sharing it, aswell as thinking about why I do stuff rn

[warm raptor]

no why ?

[hot palm]

Will not use the explanation in the document later on

[willow scroll]

Yes, they are weird if done this way. Remember to not make your class a Singleton if not needed. Only some classes like GameManager and other managers require it

[hot palm]

Yep

[hot palm]

I have switched to the use of event Action and UnityEvent for cases I would have otherwise used a static class

[burnt vapor]

I assumed WebSockets were browser specific

I would honestly just use a plain Socket class if I were you

Only drawback is risk of dropping packets
Either way the Websocket also allows byte arrays, so you can continue using that

[ionic zephyr]

How can I mantain cohesion with my attack component and make sure that I can access the same method "Attack" but it has different effects, for example, I want my enemies to attack with their own attack stat, but I want my player to attack depending on the weapon it has? Basically what I need is something that makes the player or any entity attack but in different ways, please help

[willow scroll]

I also love creating extensions, the class I derive all my MonoBehaviours from:
It, currently, has 2 partial files, and contains interesting stuff I don't like to reimplement everywhere

[burnt vapor]

So @warm raptor what is the actual data being send in that code now? Is it a bunch of boolean and float values?

[hot palm]

Doesn't EntityBehaviour already derive from MonoBehaviour?

[willow scroll]

By the way, these Actions without the event keyword are not meant to be. I have just noticed and fixed it

[willow scroll]

Yes, I derive my other classes from EntityBehavior instead of MonoBehaviour

[hot palm]

Would you mind sending the whole class over !code? I don't really get why you would define all those Events again (with On)

[burnt vapor]

IsAiming0
I assume this indicates that IsAiming is false?

[warm raptor]

exactly

[burnt vapor]

Here's the thing, you don't have to send over whole keys if what you send is always the same order

So you now send over a string and integer, when a single bit is enough

This is why it becomes messy once your game grows

For example, there's this: https://learn.microsoft.com/en-us/dotnet/api/system.collections.bitarray?view=net-8.0

[warm raptor]

yes of course, that just that it's easier for now, but I will change this later to like one or 2 character

[burnt vapor]

But at this point there is absolutely no benefit to using a string

Not to mention you are still parsing it for no reason

A byte array has everything in its place

Your floats take 4 bytes instead of how many bytes would be required for the floats currently

FYI a single character is 2 bytes

[brave compass]

I've done something like this in the past, but there is a performance cost to defining Unity event methods, even if they are empty. If many of your scripts inherit this and don't use all of the events, it's sucking performance out of your game.

[burnt vapor]

So your floats in this example is 4.5 times as big

Absolute waste of space and it will slow down everything if you do it everywhere

[warm raptor]

I'm so sorry but I don't understand why you speak of float because my whole message is a string no ?

[burnt vapor]

You're passing float values as a string

[willow scroll]

Yeah, that's something for me to think about

[burnt vapor]

A float is normally 4 bytes, and now you convert it to a string and make every single character 2 bytes

A float doesn't span a list of characters, it's numbers. But your code doesn't know that

So, a byte array just stores the 4 bytes that defines your float, and you send that over

Then the receiving client parses the bytes back to a float using BitConverter.ToSingle

[teal viper]

Are you using this library?
https://github.com/sta/websocket-sharp/tree/master
Because the dotnet WebSocket doesn't have a Send method.

[warm raptor]

yes it's this one

[burnt vapor]

Even they do conversion under the hood https://github.com/sta/websocket-sharp/blob/master/websocket-sharp/WebSocket.cs#L3461

You're just adding extra work for the same result

[teal viper]

Ok, well then you can look at their source code:

1. They have a send method that takes a byte array.
2. The method that takes a string, actually converts it to a byte array for you.

You're just doing double work with using a string

[ionic zephyr]

Is it better to attack with triggers if the hitbox is going to vary or with OverlapCircle??

[teal viper]

Here
https://github.com/sta/websocket-sharp/blob/master/websocket-sharp/WebSocket.cs#L3461

[warm raptor]

ok I'm so sorry and I might be dumb, but I saw that a bite array is some sort of a list, but if I receive this list I will still have to tell to my script where is the information for the rotation, location ... like what I'm I doing with my parsing in my script ?!

[burnt vapor]

What do you mean where it is? Your data will always be the same

Assuming your byte array first writes a float and then a boolean, the float starts at index 0 and the boolean at index 4

[teal viper]

You can use a binary reader/writer like Fused suggested, to parse the byte array.

[warm raptor]

I'm quite confuse (and my bad english doesn't help at all 🥲 ) if I send a Byte array will I just have to send the same things as my current string but in a byte array form ?

[burnt vapor]

Yes, everything is bytes under the hood

This might be confusing, but this is a packet class I wrote and maintained for a while. Here's purely the parts for writing/reading a float https://gdl.space/lowiceriqu.cs

Whole point is that is uses BitConverter for reading and writing bytes from and to the correct type

The code around it ensures it's written/read correctly by getting the correct spot from the array, and some other validation stuff (like making sure the length doesn't exceed 255 since that's the max number a byte allows)

[fervent abyss]

for (int i = 0; i < allowedApps.Length; i++)
        {spawnedApps[i].GetComponentInChildren<SystemUIButton>().onButtonClicked.AddListener(delegate
            {
      ComputerManager.instance.OpenApp(allowedApps[i]);
            });
        }

im trying to add listener to an Unity Event with parameters... but it just gives me "IndexOutOfRangeException" on allowedApps[i]?

[burnt vapor]

spawnedApps is probably not as big as allowedApps then

[fervent abyss]

it is

[teal viper]

Debug it. Don't assume.

[burnt vapor]

Then debug your code and see where it fails. This is the only assumption that can be made from this code

[fervent abyss]

brother i see it in the inspector

[teal viper]

Brother, what you're seeing in the inspector might be a totally different thing at all.

[burnt vapor]

That's still assuming. Actually validate it by logging the length of spawnedApps and allowedApps before this code runs

[warm raptor]

I barely understand something to your script 😭

[willow scroll]

If you get an IndexOutOfRangeException, it's either your eyes or Unity's visuals to doubt

[burnt vapor]

The main point is that you can use BitConverter to turn your float into a byte array and back. Most of the code just puts it inside the main byte array that is send, and also reads from this (which is what the receiving end does)

I suggest you try making something similar

[fervent abyss]

its the same :3

[burnt vapor]

It's kind of hard to make a proper byte array of data without one, but the BitReader thing also works

[teal viper]

It seems like you miss a very basic and important thing: how data in computers is stored. You should learn what bytes are.

[burnt vapor]

Then the exception is not in this part of the code. Send all your code and the full error

[warm raptor]

my brain gona explode 😰

[burnt vapor]

I also suggest your improve your code by separating it into chunks. Right now a single line can throw multiple exceptions and it will be unclear what went wrong to begin with

[burnt vapor]

Welcome to programming

Honestly if you're a beginner I'm not sure if you should be doing this to begin with

[warm raptor]

in english a Bytes is 8bit ? because im not sure of the translation

[burnt vapor]

Isn't it easier to make a very simple console application that sends some data around first?

[teal viper]

I'm 99% bytes are bytes in every langauge, but yes, it's 8 bits.

[warm raptor]

nope in french bytes are "octets" xD

[teal viper]

I guess wikipedia is lying then
https://fr.wikipedia.org/wiki/Byte

I think it's not an issue of translation, but of learning some programming basics

[warm raptor]

oh yes my bad

[night raptor]

in finland we call bytes syllables, no idea why

[languid spire]

probably because 2 bytes is a word

[teal viper]

Also, I'd say that English is very important for programmers. It is not my native language either, but I read docs and have my environment configured to be in English.

[warm raptor]

I might have understand you want me to have a message where my client could modify a part of the message, then send the exact same message that has been modified and then let the serveur modify the message again and again ?

[burnt vapor]

You want to modify the data and send it back?

You can still do that with byte arrays

However, you should understand that byte arrays assume that the data your send is always in order and of the same size. I assume your editing retains the order and types

It's weird to do this though

[warm raptor]

not necessarily, i thought that's what you wanted me to do

[burnt vapor]

It's expected you send bytes over under a specific key, and depending on this key the client knows what the data in the byte array represends

For example, key player position indicates the byte array might be three floats representing a Vector3

[warm raptor]

Oh I "THINK" i've understand !!!

but that mean that I have to send way more message to the server

[ionic zephyr]

Should my attack component be in th echild object of th e player or in the player?????????

[warm raptor]

because now I'm sending one huge message for all the different values

[warm raptor]

oh no I know, I have to put a key for each part of the message, so I wont need the "separation letters" anymore ?!

[summer stump]

Whatever works for your architecture

There is no definite answer

[fervent abyss]

solution i found?:

You’re almost there… the above is likely perfect EXCEPT that C# does “variable capture” instead of value capture.

This means that your listeners will ALL be created and use the final value of i, not an ever-increasing 0, 1, 2, 3 etc which is what you want.

what

[burnt vapor]

Right

[languid spire]

that is absolutely correct;
make a local variable
int ix = i;
and pass that to your method

[burnt vapor]

I missed the part where you made a delegate

Consider just making a method that opens the app and pass the app by reference instead of using an index into the array

That way you would not have this issue to begin with

[teal viper]

Also, proper debugging would reveal that a long time ago

That would imply you didn't actually debug log in the correct places.

Or the correct variables

[deep yew]

I never gotten this error but it decided to give it to me now

It didn't show up as an error when I added it ages ao

[slender nymph]

It's because you recently added a new using directive to your class
https://unity.huh.how/compiler-errors/cs0104

[teal viper]

Probably the wrong Random. Hover over it and see the full type name.

[deep yew]

Class system

[teal viper]

Probably "System.Random".
And the one you want to use is?

[deep yew]

The other one.

[teal viper]

"the other one"?😅

[deep yew]

Man I have no clue that's why I'm talkin' in beginners chat

Never had this error

[teal viper]

UnityEngine.Random, right?
https://docs.unity3d.com/ScriptReference/Random.html

[slender nymph]

again, this is due to you adding the System using directive. there are two Random classes you currently have access to and the compiler needs you to specify which one you want to use https://unity.huh.how/compiler-errors/cs0104

[deep yew]

Alright, thanks both of u

now it works

[warm raptor]

their is something that I still don't understand , If I'm sending my data like that

ws.send("data");

and that by doing this way it's sending a string, how can I make to send a char array ? something like that ?

char Data[] = "My data";
ws.send(Data);

because I found that apparently the socket I use can't directly send char array and instead I should send Bytes array

[teal viper]

Did you miss my message about chars being a mistake? You don't need to send char arrays.

We've been saying several times that what you need is a byte array.

Not a chat array.

[warm raptor]

oh sry my bad

[burnt vapor]

Indeed, just look into setting up a byte array and then reading from that again

[languid spire]

string has a getbytes method and the c# Encoding class will convert back to string

[teal viper]

As for the keys, if you really want to use them, you should probably replace them with an int or enum.

[teal viper]

In this case that would just be the same as what they're already doing.

[languid spire]

I'm not getting into this ridiculous discussion, just answering the last post

[teal viper]

Anyways, the main issue is all that string parsing you're doing.

Which is why a byte array would be better. It would be much faster with a binary reader/write instead of parsing the strings

[warm raptor]

Yes I know 😂 even just by looking at it i knew it wasn't the best way

[teal viper]

And finding substrings.

Which is exactly what everyone was talking about from the very start.

[warm raptor]

ok so if I use a byte array, I will receive a sequence of numbers in a list and then I would just have to tell to my script for exemple that from the [0] to the [10] it's where it's written the X coordinate ?

[teal viper]

*you will receive a sequence of bytes in an array
It's not the same as a sequence of numbers in a list.

[teal viper]

But yes, though you'll use a binary reader instead of "telling your script".

You would be telling your script the value when you have it after retrieving it with a binary reader.

[warm raptor]

so I would have to do something like that ?

x_coordinate = data.Substring(0, 10);

[teal viper]

No. You don't use strings. Or substrings. Period.

The whole conversation so far was that you don't use strings.

[warm raptor]

my bad 😅

[teal viper]

Anyways, I'm off to sleep. Good luck.

[warm raptor]

okay, thx a lot for you're help , have a good night !

[amber snow]

can anyone help me with my shader graph?

[rocky canyon]

in a coding channel?

[amber snow]

no not here, i just joined this discord and wasnt sure if i even posted my question in the right channel, and because i saw this one was more active, i thought i might just ask, whats the worst they can say?

[rocky canyon]

#archived-shaders use the appropriate channel

#🔎┃find-a-channel id:browse

[warm raptor]

so if I receive a bytes array like that :

[88, 49, 50, 89, 51, 90, 50]

wich reprensent this message :

"X12Y3Z2"

how can i get the value for the X Y and Z coordinate ?

[ripe shard]

why are you using a string format if you are sending a byte array?

i mean, just parse the string

or marshal it to/from a struct with floats/ints in the first place

[slender nymph]

why are you converting the string to chars then sending those as bytes?

you should look into how to serialize your data properly instead of making seemingly random guesses at how it works

[warm raptor]

Idk everyone told me to send my data as a bytes array

[slender nymph]

i am aware of that, but you are still doing exactly what you were also told not to and still thinking of your data as strings

learn how to serialize your data and encode it as binary, then you just deserialize it into the data you need. you don't need this middleman string manipulation

[warm raptor]

why you are now talking about binary, I'm so lost 😭

[ripe shard]

iirc you were told a lot about basic issues when approaching netcode naively without any foundational knowledge of how networking works. Maybe you would benefit from looking at a foundational intro into networking. It doesn't even have to be game related, but you should at least understand how bits go from one app/pc to another app/pc --> maybe start by looking at https://en.wikipedia.org/wiki/OSI_model and https://en.wikipedia.org/wiki/Marshalling_(computer_science)

[warm pine]

help psl

[slender nymph]

did you do what you were instructed in #💻┃unity-talk and install the InputSystem package?

[warm pine]

im not sure how

[rocky canyon]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Installation.html

[warm pine]

i dont have access to packet manager in safe mode

[slender nymph]

then next time, instead of completely ignoring that suggestion ask how

[rocky canyon]

[rocky canyon]

soo.. if u dont open it in safe-mode it crashes u say?

[warm pine]

he directed me here

[warm pine]

yes

[slender nymph]

"if there are more" was in reference to "if there are more questions after installing the input system package"

[warm pine]

ill go back to unity talk then

[slender nymph]

jsut fucking install the package if you haven't already

nobody is saying to go back to that channel to continue ignoring the suggestion. we are saying to actually follow the suggestion you were provided before anything else

[warm pine]

#💻┃code-beginner message

How can i?

[slender nymph]

exit safe mode? you were literally told to do that when you went back to unity-talk too

[warm pine]

to exit safe mode i need to eliminate the error, or unity crashes

to eliminate the error i need to exit safe mode

can you see why I am lost here now?

[rocky canyon]

if its crashing.. you'll probably need to clean it up enough in safe-mode that it doesn't crash

//comment out broken code.. or get rid of hte script until u fix it

[slender nymph]

a single error about an incorrect namespace would not cause unity to crash. in what way is it actually crashing

[rocky canyon]

^ yea, im suspicious as well

[warm pine]

It closes immedieately after opening and the bug report window opens

Ive fixed the error in the script and its loading now, Ill let you know how it goes

[slender nymph]

then i imagine something else is wrong with your project as well

[warm pine]

perhaps

[languid spire]

and, here we are again, #💻┃unity-talk message

[warm pine]

it could be because of the missing namespace, or as boxfriend said, something else is wrong

[languid spire]

forget could be. look at the damn logs and know

[warm pine]

idk how to interpret them sorry

[languid spire]

wrong logs, you are not even in the correct folder

again, that error would not have caused a crash in the editor. something else is wrong with the project. installing the webgl module to the project had literally nothing at all to do with your error. so if it was crashing prior to seeing the error as a result of the attempt to add the module then your error (while easily solveable) is not related to the crashing issue

assuming the error caused it is like breaking your arm then on your way to the doctor you stub your toe and tell the doctor that stubbing your toe is causing your arm pain

[warm pine]

is this the right log?

[slender nymph]

well i certainly won't be downloading the file to find out

[languid spire]

it might be if you posted it using a paste site

[warm pine]

alright sorry

[willow whale]

simple one for you

isPoisonBubble is set to true and yet it went down the false route

[slender nymph]

well first #🏃┃animation
and second, are you certain it wasn't already in that state by the time it was set to true?

[warm pine]

all paste sites say i have too many characters, is there a solution?

[slender nymph]

read the logs yourself or only share the relevant part(s)

[warm pine]

https://justpaste.it/eytil

[slender nymph]

that does not seem relevant to the crash

[languid spire]

I'm guessing that is the log from the copied project not the original

[slender nymph]

clear the logs, then cause the crash again and read the logs again. also i thought you said you'd fixed that error? if you had, obviously any logs related to the error would be old and no longer relevant

[warm pine]

oops sry

yh thanks

[vast vessel]

yo guys why is that last break point not being reached?

[warm pine]

https://justpaste.it/2ou1h

[wintry quarry]

Either because the video isn't long enough or because an exception is being thrown

[vast vessel]

youre right im getting a NRE

[wintry quarry]

yeah so one of the memories in the list is null probably, or an NRE in the event listener

[lethal elbow]

May need some help trying to get my projectile to instantiate in a horizontal start. It seems to spawn in standing position even though it's zeroed out in the prefab

if (Input.GetButtonDown("Fire1"))
        {
            GameObject Arrow = Instantiate(projectile, arrowSpawnPoint.transform.position, arrowSpawnPoint.transform.rotation);
            Arrow.GetComponent<Rigidbody>().AddForce(transform.forward * launchVelocity, ForceMode.Force);


        }  

[wintry quarry]

You're using arrowSpawnPoint.transform.rotation as the rotation

so presumably whatever arrowSpawnPoint is, it's oriented improperly.

or perhaps the mesh of your prefab is oriented improperly

the fix is to fix whichever of those is wrong

[lethal elbow]

This is my arrow spawn point

Generally it's shooting_origin but I was trying something out

[wintry quarry]

right so it's going to spawn the thing with that orientation.

If you look at your prefab, you should make sure the "forward" is actually correct on it

[lethal elbow]

Ah to be honest, it's not actually a prefab. Let me check that out

[wintry quarry]

BTW make sure your tool handle rotation is in Local mode

not global

also you should proably use a real prefab 😉

[lethal elbow]

Okay it's local, and everything looks zeroed out

No luck still

[wintry quarry]

i'm confused

where's the prefab

isn't this your "shooting arm"?

Where's the projectile itself?

[wintry quarry]

isn't this the same thing from here?

[lethal elbow]

Ah, second image of my original post

[wintry quarry]

yeah you can see

the blue arrow is pointing sideways

the arrow is not oriented properly

blue arrow = forward direction

yellow is "up"

red is "right"

orient your projectile prefab accordingly

[lethal elbow]

Can I do this through prefab mode?

[wintry quarry]

of course

[lethal elbow]

So the aim is to get it to face the z-axis from the prefab or the compass in the topright?

[wintry quarry]

you want the business end of the projectile aligned with the blue arrow here

when the root object of the prefab is selected

aligning it with the compass in the top right just means that your prefab root is also zeroed out, which is good practice as well

the simplest way to fix this is to move the collider and the renderer to a child object

rotate that child as needed

[lethal elbow]

So I double up on the renderer and collider? Because the object disapears if I remove it from the prefab

[wintry quarry]

no you do not double up

move them down to the child

[wintry quarry]

why would you remove it from the prefab?

[lethal elbow]

You want me to move those two into the child I made?

[wintry quarry]

instead of:

Arrow (Projectile script, Renderer, MeshFilter, COllider, Rigidbody)

Do this:

Arrow (Projectile Script, Rigidbody)
  Visuals (Renderer, MeshFilter, Collider)```

yes

[lethal elbow]

well it's not an object after that happens

[wintry quarry]

i have no idea what that sentence means

[lethal elbow]

Here it is in the child

[wintry quarry]

you didn't move the mesh filter

[queen adder]

why is this only showing out of bounds when the object is already half way out of the camera view Vector2 viewPos = cam.WorldToViewportPoint(transform.position); float verticalInput = Input.GetAxis("Vertical"); transform.Translate(Vector3.up * verticalInput * _speed * Time.deltaTime); if (viewPos.y >= 0f && viewPos.y <= 1) { Debug.Log("In bounds"); } else { Debug.Log("out bounds"); }

[wintry quarry]

what are you expecting it to do?

presumably the center of object is where transform.position is

so it will happen when the center leaves the screen

[queen adder]

when the top of the object goes out of bounds it prints out of bounds

but like you said it triggers in the center

[wintry quarry]

yes, that's where the position of the object is

the center

[queen adder]

so how can I get the top of it

[wintry quarry]

Two approaches I can think of:

• Make empty child objects at the extremities (very top/very bottom) of the object, and check the positions of those for your bounds check
• Put colliders at the edge of the screen and use physics to detect it.

[queen adder]

thank you

[wintry quarry]

Or:

• Mathematically calculate where the top/bottom of your object are and use those calculated positions in the check

[queen adder]

this is probably the best option for me

[ancient rampart]

how should I handle yamldata when importing through unitywebhandler? having some issues going from the uri to yaml data to give to yamldotnet

[lethal elbow]

Not having a good time with this one

[wintry quarry]

what problem are you having

[rocky canyon]

• Main Object (0,0,0)
  • Graphics

its pretty simple.. adjust ur child objects the way u want.. ur main root object can stay str8.. can stay scaled to 1:1:1

[wintry quarry]

also using negative scale is not usually the best idea

[lethal elbow]

Well the object looks much fatter now and rotating just the child doesn't make it alligned

[lethal elbow]

Il delete the object and just remake it, it's only a cylinder prefab

[rocky canyon]

make sure ur lookin at Local Rotations

your previous image looks correct.. (just needs scaled down).. u can see the gizmo in the top right.. showing the Z axis is facing to the left.. so ur capsule is lined up w/ that

[lethal elbow]

Doesn't spawn right still 😦

Parent is facing the right way but not the child

[wintry quarry]

we don't care which way the child is pointingt

the root of the prefab is what matters

[lethal elbow]

Ah so that is setup correctly then

[rocky canyon]

ya, bro. the child can point anyway u want it too..

the root is what matters..

(what would hold a rigidbody) (what would have its direction rotated/modified) (what would be used for orientation)

• Root
• Graphics

thats why we use this type of setup

[lethal elbow]

So this is a code issue then?

[rocky canyon]

whats wrong w/ it?

if u want it facing the other direction.. u just use the rotation part of the Instantiation method to orient it how u want

[lethal elbow]

still spawns upright

[rocky canyon]

show it after it spawns

instead of hte prefab view

and yes, its probably code related if its spawning w/ a rotation

[lethal elbow]

spawns facing up

[rocky canyon]

is it hitting anything that would cause it to rotate weirdly?

try spawning it by itself..

// Instantiate a prefab at the position and rotation of the current transform
Instantiate(prefab, transform.position, transform.rotation);```
```cs
// Instantiate a prefab at the position of the current transform with no rotation
Instantiate(prefab, transform.position, Quaternion.identity);```

when u drag the prefab into the scene hiearchy manually.. (that would be exactly how it looks if u spawn it in using code w/o rotation)

[wintry quarry]

yeah make sure it's not colliding with anything as it spawns

[lethal elbow]

il respond in 30 mins, just had to hop out

[rocky canyon]

and when u share screenshots.. select the objects in question.. and make sure not to clip anything out.. (the more we can see the better chance u have at receiving help)..

[final sluice]

is pathway down ?

[languid spire]

is this a code question?

[final sluice]

ooops sorry

[timid quartz]

I really like using Scriptable Objects for data, I like being able to edit their values right in the inspector. however, they can't be serialized, which makes me wonder if there's a good alternative out there besides using them? right now my workflow is to use a scriptable object to represent one instance of a part of the game - for example, a scriptable object per monster I want to be able to create.

[wintry quarry]

they can't be serialized
When you say this I guess you specifically mean "with JsonUtility"

[lethal elbow]

This is what happens and this is the code I have

   if (Input.GetButtonDown("Fire1"))
        {
            GameObject Arrow = Instantiate(projectile, transform.position, transform.rotation);
            Arrow.GetComponent<Rigidbody>().AddForce(transform.forward * launchVelocity, ForceMode.Force);


        }  

[timid quartz]

I don't actually know what that is, sorry.

I'm not using any 3rd party tools, this is Unity just getting mad when I add System.Serializable to anything inheriting from ScriptableObject

I am very happy to be proven wrong, if you want I can copy-paste my save and load flow

oh wow! this looks like it might solve my problem!

thank you for the thousandth time Praetor Blue, I feel like every time I come here you're always here to save my butt

[ripe shard]

scriptable obejcts are serialized by unity, what do you mean they can't be serialized?

[timid quartz]

I am using binaryformatter which doesn't work with scriptable object, but looking at the docs for JsonUtility it looks like switching to the new flow might work for me

[ripe shard]

you should stop using binary formatter immediately anyway.

did you not see the big yellow warning in the docs?

[timid quartz]

nope!

happy to make the swap, looking at json stuff now 🙂

[ripe shard]

have a look at Json.NET which unity includes by default

[timid quartz]

taking a look!

[ripe shard]

With it you can mark up exactly which fields/properties you want to serialize.

[timid quartz]

thank you! 🙂

[sleek gazelle]

It may be because you give it a rotation using transform.direction

[ripe shard]

you may also find that you don't need ScriptableObjects at all to serialize your data to disk.

[timid quartz]

I like using them because I like being able to drag and drop them around and edit their values right in unity

[ripe shard]

yes, but you do not have to serialize the SO directly, you can just use it for that access and implement the serialization with plain c# objects

which is much simpler because with SOs you need to .Populate an existing object which is often not supported by serialization libraries (though Json.NET supports it)

with a plain struct or class you can just have the serializer create a new instance without any unity object lifecylce issues

[strong wren]

I'm not sure if Json.NET necessarily ends up in all default projects. Add com.unity.nuget.newtonsoft-json by name in package manager if you don't have it.

[lethal elbow]

Well it shoots forward when it there is no angle from the character. It's only when you aim away from the centre of the z-axis

Ignore that, it's always facing up no matter the direction

[ripe shard]

you may also need custom serializers for some unity types. Something like this https://openupm.com/packages/jillejr.newtonsoft.json-for-unity.converters/

[strong wren]

Pretty sure Unity has converters for most of the common types.

[lethal elbow]

The only thing I can think of is the projectile only heads in the direction the camera is facing

[slender nymph]

i think that's the same one, actually. the person who made it also did the newtonsoft package that unity forked

[meager gust]

because parsing strings is slow. that's a fact.
reinterpreting 4 bytes as an integer, or 2 bytes as a short, etc is lightning fast on the CPU.
you just deserialize the bytes into variables the same order you serialized them. there's no real parsing needed.

as other people said: it's byte, not char. bytes are literally just raw memory on a computer.

public void Serialize() {
  write(variable1); // int32
  write(variable2); // short16
}

public void Deserialize() {
  variable1 = readInt(myByteArray);
  variable2 = readShort(myByteArray);
}

we don't need to parse anything, because we already know that an integer will always be 4 bytes, a short will always be 2 bytes, etc. we can just increment the position after every read/write.

[sleek gazelle]

Yeah but you're still giving it a direction. Look at the direction of the main player, the one that shoots the bullets and set all the 3 values to 0, you might find that now your player is sideway

[warm raptor]

so I have to send one message for each variable ?!

[meager gust]

no

you load them all into a byte array

the byte array is your message

that was very incomplete psuedocode

[warm raptor]

I must be dumb but I still dont understand how it work

[obsidian kite]

hey guys im having problems with point light on unity hdrp
https://www.reddit.com/r/Unity3D/comments/1ejcz4f/help_with_lighting_hdrp/

if anyone could help id be grateful

[meager gust]

@warm raptorhttps://learn.microsoft.com/en-us/dotnet/api/system.io.binarywriter?view=net-8.0

look at the example. see how familiar that looks to my example?

[lethal elbow]

I changed the code now, instead of it facing up it now faces forward no matter the direction i'm facing. Meaning it faces forward on a global scale (Always facing towards the X-Axis)

[sleek gazelle]

Ok

[ionic zephyr]

How can I make a system in which I drag a slot´s item image and drop it in other slot and that second slot gains the first slot information??

I´m using these interfaces for now but I don´t really know how to detect that the place I am dropping the image is a slot for example

[rigid ridge]

So i made this simple dash but how do i make it that i only can dash once and not again until i touch the ground again

[meager gust]

@warm raptor
the whole underlying basis is that memory is stored in bytes. you understand?

every integer (32 bits) will always be 4 bytes in computer memory.
every float (32 bits) will always be 4 bytes in computer memory.
every short (16 bits) will always be 2 bytes in computer memory.

It's just very easy to convert the values to bytes.
bytes are how data gets sent over the internet.
when you send a string over your websocket, it breaks it down into a byte array before truly sending it.

[warm raptor]

I understand that it's stored in bytes but i don't understand how it work how can integer always be in 32bits , because it would say that you can't have an integer bigger than sommething like 200 000 000 ?!

[slender nymph]

the max is about 2 billion for a signed int yes.

this is basic information that you should absolutely already know before attempting to do any sort of networking

[warm raptor]

but that dumb, because their are so many case where we need to go above 2 billion ?!

[slender nymph]

well there are other data types you could use for that. which is, again, fundamental information you should have before attempting to do what you are attempting to do

[warm raptor]

I love to see that I know nothing on how the script is interpreted by the computer 😭

also I just see that the web socket I use send the data in binairy, should I go to
e.RawData
instead of
e.Data
?

[meager gust]

64 bit unsigned (ulong) integer max size is
18,446,744,073,709,551,615
which you'll probably never need to use a number that big 🙂

[ionic zephyr]

how can I get a component from the object I am dropping my slot image on??

I want to add the slotData of the Slot image into another slot in which I drop this image

[slender nymph]

clicker games would like to introduce themselves.

[wintry quarry]

I think eventData.pointerDrag.GetComponent<...>

[ionic zephyr]

let me try

[warm raptor]

physics enter the chat* 😅

[slender nymph]

that would be the dragged object, not the object it is dropped on, no?

[meager gust]

physics engines use 32 bit computations. at least physx does.

[wintry quarry]

i don't remember

could be

I always have to re-figure out how to do drag/drop

[slender nymph]

could just raycastall from the event system at the position the object is dropped

[ionic zephyr]

My idea is to drop the slot image onto another slot which receives the first slot data and adds it to it

[warm raptor]

but their are numbers that are insanly big in physics ?!

[ionic zephyr]

how could I do that?

[slender nymph]

start by googling it

[ionic zephyr]

with PhysicsRayCaster2D?

[wintry quarry]

definitely not physics

[slender nymph]

"from the event system"

I tried to make paralax effect but somehow it always out of bound and always moving at same speed

why my camera position different than my background position? even though it placed perfectly on the same place

[slender nymph]

why are you multiplying a position by deltaTime

[twilit iris]

some tutorial said to make it updating at same rate on any device. So I tried it to debug my problem beforehand. Yeah didn't change anything

[slender nymph]

it makes absolutely no sense to multiply a position by deltaTime

[rose canopy]

so, im having a problem that i have never had before in my years using unity, i THINK it might be a memory leak, but honestly i have no idea and ive never dealt with a memory leak before, but when i start up my project which btw is a practically empty project right now, it runs great, 200fps in play mode, but then as soon as i change something in the scene for example changing a value of my move script, add/remove any script, add/remove a mesh, ANYTHING, my frames instantly are reduced to a constant 50/60fps when already in playmode or when clicking play the next time until i reload the scene or restart unity. No fucking clue whats going on here any help is appreciated

[twilit iris]

wait I'll change it if it was the culprit I'm going to cry alone

nope still broken

[rigid ridge]

Anyone pls

[queen adder]

is this the palce to talk about camera

[ripe shard]

this place is called "code-beginner"

[queen adder]

Yea but can i talk about camera is there a way to make it stay one Z position at all times

[frosty hound]

Sure, when you move the camera's position, set its z position to what you want.

[queen adder]

okay thanks

I'm trying to write code to make it so that when 2 objects collide, they merge into 1. But instead both disappear because the code is running at the same time on both objects.
Not sure how to avoid that.

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.GetComponent<ItemPickUp>() != null && quantityToPickup < ItemData.MaxStackSize) //if it's another item and this current item has capacity to merge
        {
            var itemOnFloor = other.GetComponent<ItemPickUp>();

            if (itemOnFloor.ItemData == ItemData) //if both items are the same
            {
                int availableToMerge = ItemData.MaxStackSize - quantityToPickup; //finds amount that it can add to stack

                if (itemOnFloor.quantityToPickup < availableToMerge)
                {
                    itemOnFloor.quantityToPickup = 0;
                    quantityToPickup += itemOnFloor.quantityToPickup;
                    quantityText.text = quantityToPickup.ToString();
                }
                else if (itemOnFloor.quantityToPickup >= availableToMerge)
                {
                    itemOnFloor.quantityToPickup -= availableToMerge;
                    quantityToPickup += availableToMerge;
                    itemOnFloor.quantityText.text = quantityToPickup.ToString();
                    quantityText.text = quantityToPickup.ToString();
                }

                if (itemOnFloor.quantityToPickup == 0) //if the other item is full consumed then destroy it
                {
                    Destroy(itemOnFloor.gameObject);
                }
            }
        }
    }

[wintry quarry]

jsut make sure it only runs on one of them

[eager wolf]

Yeah... but how? 😅

[wintry quarry]

a cheeky way is something like this:

if (gameObject.GetInstanceID() > other.gameObject.GetInstanceID()) return;```

[eager wolf]

Works, thanks a lot!

can anyone explain the code in the update function

im really confused

[rocky canyon]

it sets the sprites parent to the scripts gameobject.. tracks it.. and uses velocity to squash and stretch the local transform of the child object (the sprite)

[rigid kite]

void Movement()
    {
        float speedX = Input.GetAxisRaw("Horizontal");
        float activeSpeed;
        if (Input.GetKey(runKey))
        {
            activeSpeed = runSpeed;
        }
        else
        {
            activeSpeed = walkSpeed;
        }
        rb.velocity = new Vector2(speedX * activeSpeed, rb.velocity.y);
    }

Hello guys. I am making a 2D game with Rigidbody movement. How i can make my Player move with rb.AddForce without being slippery?

[wintry quarry]

Wdym by "slippery"? You mean having momentum?

Objects have momentum, that's how physics works

If you want no momentum at all you can just set velocity back down to zero whenever you want.

otherwise, you can control how fast to slow down by applying braking forces

[rigid kite]

how i can add breaking forces

[wintry quarry]

With AddForce

[rigid kite]

But like to what direction

[wintry quarry]

and it's braking* not breaking

[wintry quarry]

the opposite direction that you're moving in of course

[rigid kite]

you know its begginer bro

if i could do it i wouldn't ask it to this server

[wintry quarry]

I don't know what you're trying to say, but I'm explaining how to do what you want to do

[rigid kite]

ok bro ty

[strong wren]

how can i turn a gameobject into a prefab without breaking the Variables?

my prefab looks like this

[wintry quarry]

prefabs can not refer to any objects in a scene

[strong wren]

well the component prefab

[wintry quarry]

so if you have any references to scene objects, they won't persist in the prefab

[strong wren]

alright, so for example the S is for another script if i turn the gameobject with the S script into a prefab can i then bind it and will it then work?

[wintry quarry]

depends what you mean by "work"

depending on what that S is, it's not going to actually do anything

since it's a prefab and not in the scene

[strong wren]

yeah but once it is in the scene

[wintry quarry]

prefabs are things that live in your project folder

that would be a different object than the prefab

it would be an instantiated copy of the prefab

your prefab cannot refer to objects in the scene.

regardless of if they are copies of a prefab or not

[strong wren]

soo what can i do to make the enemy into a prefab with the same components?

[wintry quarry]

it has the same components

what you need to fix is how you get references to those things

you can't use inspector drag and drop for this

[strong wren]

i fixed the S, ST, and SP since they are trying to access a script but the PlayerBody is a gameobject and even if i still turn it into a prefab it wont work

[wintry quarry]

I feel like you're missing the point of what I'm trying to say

[strong wren]

no i think im not explaining correctly

it works i made it so they work now

[wintry quarry]

You either use something like the singleton pattern or have the script that spawns these things pass the reference they need to them after spawning it

[strong wren]

i just need the PlayerBody To be set

[strong wren]

interesting

[wintry quarry]

There's a difference between "you managed to get something dragged into the inspector" and "your game works as you intend"

you'll see

[strong wren]

again i dont think i explained myself correctly but that is irelevant now

[strong wren]

whats simpler?

[wintry quarry]

Singleton.

Assuming they are actually singletons

[strong wren]

hopefully they are

[wintry quarry]

SOmething lIke "shop" or "stats" doesn't seem very singleton

[strong wren]

those are scripts

[wintry quarry]

obviously

[strong wren]

yeah

[wintry quarry]

singleton means "there's exactly one of them in the world"

[strong wren]

the playergoto is now the issue im facing

oh

then it should work? the playergoto is in the world

[wintry quarry]

and there's some code pattern to take advantage of that for easy references

[wintry quarry]

I think you're expecting some magic to happen. You will need to write some code and change some existing code to use the Singleton pattern.

[strong wren]

poop

i mean i can probably make it so the ememy goes to the player differently

like instead of going to a specific gameobject it checks for a gameobject with a specific tag in it then it goes it?

[wintry quarry]

This is a very solved problem with very well known solutions

yes, that's one of the solutions

https://unity.huh.how/references

[strong wren]

woudlnt i be using raycasts for that then?

[wintry quarry]

Huh? Raycasts?

[strong wren]

idk last time i watched a tut on raycasts it said smth about info of a gameobjec

ima read the link first

[wintry quarry]

You're conflating and confusing things

you can get a reference from a raycast sure

if you happen to have been making a raycast in some known direction

but it doesn't sound like you're doing that.

That would be for like some kind of searching behavior

[ancient rampart]

I have successfully gotten my yaml to parse, now I need to figure out how to make it accessible to other scripts, how can I go about making this var visible to a different script?

[eternal needle]

the same way you do with any variable, either make it public or give it a property with a public get and private set

but that seems to be a local variable, it needs to be declared outside a method

[ancient rampart]

here's the context of the line, and yeah adding public in front of it just breaks everything lol

also been a long day of trying to get this to work hahaha, not entirely understanding what you mean by declaring outside a method

just like at the top of the script?

[eternal needle]

well you should really start with c# basics then, if you dont understand what outside a method is

[ancient rampart]

honestly just never heard someone use the term method before with this stuff, but fair

[teal viper]

Then you haven't learned C# at all. Because it's one of the most used words in it's context.

[ancient rampart]

good thing I'm in the beginner chat 😉

anyways ima dip, but thanks

[teal viper]

It being a beginner channel doesn't mean that we're gonna make C# basics lectures here for anyone lazy enough not to learn them on their own.
And spoon feeding such people would just make them get used to getting easy answers without putting any effort.

[neon meteor]

hey i was wondering if i could get some help with some code?

i'll just post it here. any help would be greatly appreciated.
i just need a simple walk script where i can move around with wasd, jump with the space bar and look around with my mouse.

lastly, i need to make a separate cube that when the player touches, they get sent back to the starting point (they die essentially.) thank you in advance.

[subtle hound]

i had a problem with this where it grabs the prefab's transform instead of my object in the scene

how can i grab the in scene objects transform here?

been tinkering and bugtesting this all day 😅

[teal viper]

Where should we be looking? Are you talking about the commented out code?

[subtle hound]

no

the line above debug log

tile newtile = (tile)boardmanager etc

thank you

right above the commented code

[teal viper]

If you're absolutely sure it returns the prefab transform, then the issue is in the GetTile method. You'll need to debug that.

You can pass an object as a second parameter to the debug log. This would highlight the object when you select the log message. Can be useful for confirming what it actually references.

[subtle hound]

THANK YOU

very helpful info for debug

appreciate the help

[strong wren]

i have no clue what ive done

and now there is kind of a saving mechanic in my game

i made the enemies into prefabs then made it so instead of the enemy going to a specific gameobject it searches for a gameobject with a specific tag then goes to it and now my money is being saved

i mean i aint complaining

i mean i know how to fix it

[subtle hound]

it highlights nothing!

does that mean its the prefab reference not the object in my scene

i would assume so?

im in the game display i dont know if maybe my settings arent right to see this outline

[teal viper]

It would highlight a prefab too. Do you have the assets tab open?

[subtle hound]

sec

yep it highlights the prefab

guess i have to debug gettile

[rocky canyon]

no clue what that means, but hey, if it works it works..
generally: prefabs can't access things in teh scene.. and scenes cant access whats within a prefab..
until after u instantiate it..
then:

• its common to either search for the components in teh scene u need..
• assign them via the script that did the instantiating..
• or simply u can just add the scripts to the prefab

[subtle hound]

but when i google it says i just need to instantiate it first 😅

so i feel likke i did that

any intuition here?

[strong wren]

i have no clue but i think its that i made the gameobject that has money into a prefab? i have no clue myself?

i mean its neat

i know how to fix it

[teal viper]

Hmmm..? Oh GetTile is not your own custom method?

[subtle hound]

nope

just a tilebase method

[strong wren]

eh il make it so once the game starts it makes it so the money = 0

I'm beginning to think the tutorial I'm following is maybe not very good? This feels very analogous to something Boxfriend told me last time I was on here.

Yeah what the hell.

[teal viper]

That's why you should be sharing the whole !code correctly. I have no way to tell what objects are of what types there.

Hastebin is awesome.

Always use it if you can.

[rocky canyon]

it only works half the time

[subtle hound]

aha myy bad i wasnt trying to overcomplicate things but

[strong wren]

my money is stored on a gameobiect but now instead of storing it on a gameobject it stores in it the prefab

and it seems like its updating but it isnt

the whole file?

[teal viper]

I'd assume that one of the references before GetTile is actually a prefab, but it's hard to say without debugging properly and seeing the whole code.

[subtle hound]

mhm ok

[teal viper]

See the bot message? Read it.

[subtle hound]

sryy 🙂 bad discord ettiquette

[bold plover]

Yeah, snippets very rarely are enough to go off of. Things like that are your friend since you likely have tons of interlinked code making reference to one another.

I need to get more into that habit myself too so don't feel too bad.

[rocky canyon]

still use the gameobject like u did before.. if ur prefab needs a reference to it and its in teh scene
store the reference on the thing thats spawning the prefab.. then u could just set it..

like ur example had S for spawner..
public Spawner spawnerReference; // <-- on the script that spawns the prefab
then: when u instantiate it..

ChildFollow newChildFollow = instantiate(childfollowprefab);
newChildFollow.S = spawnerReference;``` tha'd be the easiest way i can think of

[strong wren]

yeah i need to set the variables to the stuff on scren

[rocky canyon]

but you could also use a singleton.. and have 1 gamemanager type class that holds all the important references from the get go..

you need something important... just access that..

[strong wren]

like i need it to be refrenced

i tried using singletons but im having a hard time with them

[subtle hound]

https://gdl.space/nixexasadi.cs movingobject script
https://gdl.space/fovihiyiyo.cs enemy script subclass of movingobject - this is the movingobject im testing
https://gdl.space/oseqevewuy.cs game manager, it moves pieces around and manages the current state of the game
https://gdl.space/fozowecopu.cs board manager, sets up the board and places pieces at the start of the scene

dont expect u to go through a bunch of work just posting in case u wanted to help xp

not all my files but everyything associated with the problem im sure

some comments may be outdated

[rocky canyon]

they're pretty simple once you start using them. ```cs
public class MyScript : MonoBehaviour
{
public static MyScript Instance { get; private set; }

[SerializeField]
private ScriptA scriptA;
[SerializeField]
private ScriptB scriptB;

private void Awake()
{
// If there is an instance, and it's not me, delete myself.

  if (Instance != null && Instance != this) 
  { 
      Destroy(this); 
  } 
  else 
  { 
      Instance = this; 
  } 

}
}``` to access Script A from anywhere: MyScript.Instance.scriptA;

[teal viper]

Ah, right. Actually, a Tile is an asset. It doesn't exist in the scene.

[subtle hound]

Ah!

how can i fix this

abandon tilebase mostly?

[teal viper]

if you look at the TileBase docs, it inherits from SO.
https://docs.unity3d.com/ScriptReference/Tilemaps.TileBase.html

[teal viper]

Depends on what you're trying to do.

[subtle hound]

anything is fine i just thought tilebase would be easy because i have a grid based rpg game

i use tile for the floors and walls etc

[teal viper]

Thing about the Tilemap system is that it only stores the barebones instance data required for rendering. And it stores it internally.

[subtle hound]

i want something with good storage like i dont want to do a big matrix of all the tiles

i feel like thats bad for scalability of my game

i want to have a larger board

[teal viper]

You mean an array?

[subtle hound]

right sry

[teal viper]

Well, you'd need to use a 3d array or a dictionary. There's no going around it, since unity doesn't do it for you

[subtle hound]

ok

so it doesnt raise danger flags doing a 3d array alright

as long as i manage it properly?

[bold plover]

Error on line 23 of Player.cs which is CS0120. Trying to fix it by declaring line 7 in PlayerStateMachine.cs as static causes CS0176. I'm trying to pass acceleration and top speed values for specific states into the main player's script. I keep reading documentation but it's not clicking on how to fix it. Any help appreciated as I feel pretty hard stuck.

[subtle hound]

i was relying on my instincts mostly that sounded inefficient at first

[teal viper]

Yes. Obviously if you have huge/infinite world, you'd need some kind of streaming system or something.

[wintry quarry]

you know people don't memorize error codes

sharing your actual error message would be a million times better

[subtle hound]

could you give me better terminology for what a streaming system is so i can google ? it just comes up with "streaming services" haha

or a brief explanation would be very helpful

[rocky canyon]

tack Unity to the end 😉

[wintry quarry]

This is what you're meant to do:

float groundAcceleration;

void Start() {
  StateMachine.Initialize(BaseState);
  groundAcceleration = StateMachine.CurrentPlayerState.groundAcceleration;
}```

[teal viper]

Maybe google "level streaming". The concept is the same - loading data from disk or generating it at runtime such that you don't have your infinite world eat up all the memory.

[subtle hound]

great ty for all ur help i think my solo journey starts here

[bold plover]

Noted.

And holy crap thank you.

❤️

[wintry quarry]

BTW it seems like a bad idea to duplicate this groundAcceleration field

you shouldn't need a copy of it on this script and on the state

it will lead to you having to constantly synchronize it

[bold plover]

Yeah I'm confronting that the tutorial I'm following might actually have been terrible the entire time.

yeeeeep

[wintry quarry]

You should just read it from the state whenever you need it

[bold plover]

🙃

[wintry quarry]

you could make a property to make that easy

[bold plover]

Like why have it if I am duplicating the code anyway lmao.

[rocky canyon]

if u learn what not to do.. its still a pretty good tutorial then eh? 🫠

[wintry quarry]

private float currentGroundAcceleration => StateMachine.CurrentState.groundAcceleration;```

[bold plover]

There's so much bad coding advice online.

[wintry quarry]

absolutely

but the biggest issue is that, you can't take anything as a hard and fast "this is always the best way" rule

[subtle hound]

not here 🙂

[bold plover]

real

[wintry quarry]

there are different ways to do almost everything and each is good in different scenarios

[bold plover]

Yeah if you do it right the first time you don't have to add more spaghetti to "fix" it.

[rocky canyon]

yup. , just fact check everything

you'll be a better person b/c of it

[wintry quarry]

honestly this is kind of a myth that beginners believe too.
The reality of software development is that you will be constantly rewriting it as time goes on and priorities and requirements change

[rocky canyon]

unless, ur just a God of hindsight 👇

[wintry quarry]

foresight!

[rocky canyon]

that ^

[bold plover]

Well, that is cathartic to hear anyway. Makes me feel like I didn't waste as much time. And it could be argued that it teaches me how to fix it in the future as needed.

[rocky canyon]

absolutely

only worthless if u got no worth out of it.. lol (and u came here for 2nd opinions.. sooo.. 👍 )

[strong wren]

oh ur right

its pretty easy

[rocky canyon]

100 percent.. just dont complicate it lol.

[strong wren]

dayum

i expected it to be harder

[rocky canyon]

singletons are 🪄

thats why they're typically used for GameManagers, CameraManagers, and whatnot

[strong wren]

it isnt u just rename 1 thing to the name of the script ur using then in the script where ur accesing the other script instead of doing S.Money++

you do
Shop.Instance.Money++;

i mean in my case

[bold plover]

Yeah, my biggest hurdle has been adjusting things after they've become larger and dependent on one another.

[rocky canyon]

they can stick around.. and hold important data/ call important (GLOBAL WIDE) type of functions

[rocky canyon]

since ur using 1 now.. here's the source material i got that singleton snippet from.. might wanna skim over it just so u have some context about them
https://gamedevbeginner.com/singletons-in-unity-the-right-way/

oh i used a tut lol

im more slow then others and videos make it eaiser for me to understand

[loud owl]

IDK if its begginer or not but im trying to learn MLagents and i want to make a 2d flappy bird ai

I get the basics of rewardingü actşıbs and observation

How can i let the ai know what to do in flappy bird logically?

like its a weird question but in a 3d movement game

i can teach ai to toucha coin for example

but i cant imagine what to do in flappy bird

get the birds location and the pipes empty parts location maybe? but i cant get it normally because its prefabs as far as i know

I watched a few yt videos and people are using rays but just wanted to ask what to do

sorry for yapping a lot

[rocky canyon]

like dis

[loud owl]

Yea, I saw that code monkey guy but its a really hard to understand tutorial for beginners

he is just skipping parts and not explaining enough atleast for me

[rocky canyon]

CodeMonkey has a 2d version

[loud owl]

yea yea in that part

https://youtu.be/fz8D0OZkQGQ?list=PLzDRvYVwl53vehwiN_odYJkPBzcqFw110
