ah cool

[grand snow]

hehe

If you want to save some inventory state it should be something like:

{
  "items": [
    {
      "id": "gun",
      "amount": 1
    }
  ]
}

then when loading the save data you use the id to retrieve the "gun data" for example
you cant just try to serialize the unity scriptable object as json... its gonna produce junk

you can load scriptable objects at runtime for items and then use the id to find it for example

[dull grail]

Thank you

[silver fern]

hm serialized enum doesnt show up in the editor

[naive pawn]

...what?

enums aren't supposed to show up

fields of enum type are though

you sure you're looking at the right thing? perhaps show the declaration and stuff

[ember tangle]

Does it make sense to have all the data in my gameobject as a struct so I can save it easier?

[grand snow]

makes no difference when its saved

[dull grail]

You may search for plugin which add serializable dictionary and do something like this

[silver fern]

I'm probably doing this wrong https://i.imgur.com/EoZBz4O.png

[grand snow]

ha yes you are

thats the enum declaration

use it as a type when declaring a var

[silver fern]

ahh got it thx

Is there any best practice or whatever on where to put the enum declaration or can I just put it in front of the variable declaration?

[naive pawn]

put it where it's relevant

you won't be using it just one place

[grand snow]

better to not have it inside a class as it makes using it elsewhere require Class.Enum

[naive pawn]

you'll be using it when you want to use the field of that type too

[fresh rampart]

Can you tell me what this is about? there is nothing on the stage and there are still such errors, the unity version is 6.1 (6000.1.10f1)

[silver fern]

I don't think I need to use this particular enum anywhere else tbh

[slender nymph]

Those are warnings, not errors. And unless you're actually experiencing an issue you can probably ignore them

[dull grail]

Try to restart editor first, i had same errors and they disappeared only after restarting even if i'll remove everything

[naive pawn]

you will need to use them when you use the field later

[silver fern]

wdym

[naive pawn]

i mean what i said

[silver fern]

well I don't understand what you said

[dull grail]

Just move enum to a different cs file

[naive pawn]

how were you checking the damage type before?

[silver fern]

It was a string that can take one of three different values, and I was looking to restrict it to those three values

so its just string comparison

[naive pawn]

you don't have strings anymore though

so you can't do string comparison

you would do comparison against enum members instead

[silver fern]

maybe enum is the wrong solution

[grand snow]

it is the right solution

enums are actually an int so that means faster comparison later
e.g. if(damageType == DamageType.Physical)

[silver fern]

ok, well this is in the variable declarations part at the start of the weapons controller, so where should I move it then?

make a new script and import it in the controller?

[naive pawn]

if it's relevant to all weapons, i would just put it in that file or that class

[naive pawn]

you don't need to import stuff in the same assembly

[silver fern]

it's relevant to all weapons, but each character has a different weapon controller script

[dull grail]

Try something like this

foreach (var entry in damageList) // damageList is dict with key presented as DamageTypes enum
        {
            // True damage bypass any calculations
            if (entry.Key == DamageTypes.True)
            {
                health -= entry.Value;
                continue;
            }
            
            if (dmgResists.ContainsKey(entry.Key))
            {
                reducedDamage += entry.Value * (1.0f - dmgResists[entry.Key]); // or whatever logic you need
            }

[naive pawn]

this is.. kinda unnecessary

also don't spoonfeed

[silver fern]

can I have this enum declaration in every weapon controller script or will that cause an issue

[naive pawn]

that will mean you have several enums that happen to have the same name

you probably just want 1 enum

do you have any centralized weapon-related script? if you do, i'd probably put it there

if not, its own file would be fine

[dull grail]

Alright, my bad, but what's unnecessary here?

[silver fern]

no because every character has different abilities so the scripts have nothing in common except these basic variable names

[naive pawn]

if you're going to use all 3 types like that, may as well just have a struct with 3 floats/ints
it's making some assumptions and not making others, so it's trying to be flexible in a weird way

[naive pawn]

not even a shared interface/superclass?

[silver fern]

for what?

[naive pawn]

the weapon controllers

[silver fern]

yeah I mean for what purpose would I have that?

or what would be in it?

[naive pawn]

being able to have core logic that's shared between classes

even simple things like having an owner

or making sure some functionality is included, specifying common method names

or being a common interface that you can assign to stuff without having to use MonoBehaviour

[fresh rampart]

Because of this, there is a very strong fps drawdown and lags.

[silver fern]

the only thing they might have in common is reading the mouse position in Update() I suppose

[naive pawn]

imagine you add controller support, now you have to rewrite that logic in however many weapons you have instead of just one central base weapon

[silver fern]

I'm not sure the game would even be playable with anything but keyboard and mouse

[naive pawn]

it's a theoretical, i barely know anything about your game

[silver fern]

How would that work then? Should the weapon controller only have the mouse position update and then import the rest from another script?

[dull grail]

The point is you can make 1 base script which will be inherited by other scripts and you can just change base logic in 1 place instead on redoing it in every script separately

[naive pawn]

no, the other custom weapons would be extending the base weapon controller

[silver fern]

I can't find consistent information on how to do this

every site is saying something different

[polar acorn]

That tends to happen when there's multiple ways to do something

[silver fern]

then how do I do it

[grand snow]

its a general object oriented programming concept using inheritance

[polar acorn]

I just got here I don't even know what "it" is at the moment

I was just pointing out that there are often many ways to achieve the same goal and which one is correct is highly dependent on the situation you're using it in

[silver fern]

maybe I should use a dictionary instead of an enum

or something

[naive pawn]

probably not, given that you wanted limited options

[silver fern]

well I don't see how to do what you said

so enum isn't gonna work like this

[naive pawn]

huh?

that's unrelated

[silver fern]

you said I had to do it this way to use the enum in multiple controllers

[naive pawn]

no i didn't

i said you can't put the enum in multiple places

the above like, 30 messages, were just trying to find that central place

[silver fern]

and I told you there is none

[silver fern]

ah I didn't see that

so I make another script containing just the enum, attach it to the gameobject in addition to the controllers, and then import the enum from there?

[polar acorn]

Honestly you should be defining enums in their own file pretty much always

[polar acorn]

An enum is not a component. You don't attach it to an object

[naive pawn]

why are you so set on importing stuff lol

[silver fern]

but a script is and chris said to make a new script for the enum

[naive pawn]

script != component

[polar acorn]

A script is not a component

[silver fern]

then where do I put the script

[polar acorn]

Wherever

[naive pawn]

a script is a file that contains code

a component is a class that extends UnityEngine.Component
classes live inside scripts
thus, components live inside scripts

[polar acorn]

Making a class that inherits from MonoBehaviour makes that class a component (because MonoBehaviour also inherits from Component)

A script is just a file containing code

[silver fern]

I mean these https://i.imgur.com/cYbDHtL.png

[polar acorn]

If your code isn't a MonoBehaviour it isn't a component

[silver fern]

as you can see there are script components and other components

[polar acorn]

Components

Enums are not components

Enums are types

like int and string and Vector3 and whatnot

[naive pawn]

they are all components
the components are defined inside scripts

[silver fern]

then why does it say script on only the ones at the bottom

this is confusing

[naive pawn]

because those are from your scripts

[polar acorn]

Because those components are defined in scripts as opposed to being built in

[naive pawn]

the others are from packages or built-in, where it isn't really touchable as a file

[polar acorn]

"Why are all of my squares saying they are rectangles when you're all trying to tell me rectangles are not squares"

Scripts can contain components, but they are not the same thing

public class Thing
{
  public int Num;
}

Slap this in a .cs file and you have yourself a bonafide script-that-doesn't-contain-a-component

[silver fern]

the confusing thing is that some are explicitly labeled as rectangle while others are not and I'm supposed to infer they are both rectangles

[polar acorn]

Because there are some components that are not defined in scripts. They're part of the engine. There is no Collider.cs file in your project

it's a Unity component

that is not a script

[silver fern]

chris just said they are all scripts

anyway, so I make a new script in the script folder with all the other scripts, and define only the enum in it yes?

[polar acorn]

No actually they literally just said the opposite

[silver fern]

#💻┃code-beginner message

[polar acorn]

You need to understand that saying "Scripts contain components" is not the same thing as saying "Scripts are components".

[naive pawn]

components live inside scripts
the components that are marked (Script) are those from your scripts

[polar acorn]

"Components live inside scripts" != "Components can only come from scripts"

This is programming. Statements mean exactly what they say and nothing more

[naive pawn]

(that is what i'm saying though, there are scripts for built-in or package components. they just aren't accessible as scripts, as in files of code, within the context of your project, so it's not useful to refer to them as scripts)

[polar acorn]

The following are axiomatically true and do not conflict:

• Components can be attached to GameObjects
• Components can be defined in scripts
• Components can be provided by Unity
• Scripts can contain components
• Scripts do not need to contain components

[polar acorn]

Some of them exist in DLLs which are compiled C++ code, they're not really "scripts" in that they're just a sort of amalgam of machine code rather than discrete script files within it

[naive pawn]

do they not all have c# interfaces?

ie unity's Collider.bindings.cs

[polar acorn]

I don't know if I'd count a file containing basically pure externs as "A C# script" but at this point we're just being pedantic and probably confusing the matter even more

[naive pawn]

true

[silver fern]

true

so about that enum script

[polar acorn]

Just a file with the enum in it

Not inside a class in the file

just file containing enum

[silver fern]

ok. normally, to reference another script, I'd use GetComponent(), but since this is not a component, how do I best use the enum in the controller script?

[rich adder]

when you make an enum its kinda its own type

enum CoolEnum {One, Two, Three}```

// any script
private CoolEnum myCoolenum;
void Foo(){
myCoolEnum = CoolEnum.One``` etc.

[naive pawn]

GetComponent doesn't reference another script, it gets an instance of a component
the instances of an enum type are its members

"referencing" is just.. using its name

[silver fern]

so it will just automatically know to use the enum definition in another file even if that file is not referenced anywhere?

[polar acorn]

You don't reference an enum

it's just a type

You use it like you'd use int

[rich adder]

^ enum is not a reference type, a numerical type (its literally in the name)

[naive pawn]

unless you're using your own asmdefs, your entire project is within the same assembly

have you been importing the files for your other components?

[silver fern]

well there was no need to since they're all self contained

but they have stuff like using UnityEngine;

[naive pawn]

0% interop 100% modularity is insane

[silver fern]

😟

[naive pawn]

but anyways yeah to finish out that thought - in c#/java, there is a concept of namespaces (packages for java), where everything in a given namespace can use everything else in the same namespace directly

[rich adder]

enum can also be in a namespace if designed as such you'd need also its containing namespace

namespace AwesomeSpace {
enum CoolEnum { etc .}
}

//script 
private CoolEnum coolEnum; // not found unless you do using AwesomeSpace
or
private AwesomeSpace.CoolEnum coolEnum```

[naive pawn]

and "no namespace" is also its own namespace, the anonymous namespace

(unlike js/ts/py where it's just files)

[silver fern]

ok, I see

I thought it would ignore files if I don't explicitly tell it to use them

[rich adder]

there is no concepts of "files" in codespace

thats just for human organizing

[naive pawn]

(in c#/java)

[rich adder]

lets do most* ig lol

[silver fern]

I didn't think it would add the contents of that file to the codespace if I didn't explicitly tell it to

[naive pawn]

really? it seems like half languages ive seen need to import stuff directly from files

[rich adder]

I'm just assuming tbh. I only knew a handful and mostly are C family anyway

except I guess for Header Files if you chose so in c++ ?

[silver fern]

most of the ones I know need explicit imports

[rich adder]

they are files but whats inside the file anyway is more code lol

imports and namespaces are pretty similar

or maybe more of assemblies thing ig

[naive pawn]

implicit sharing, no mention of files, import gets all
c# & friends - namespaces
java & friends - packages
file names, import gets all
ruby, c/c++
file paths, import gets all
sh
file paths, import gets specified
js/ts, py

apparently it's not something very generalizable, the more i think about it

[silver fern]

alright, thanks a lot everyone

Is there a way to find a specific subcomponent of a game object from another component on a different branch of the game object tree?

[naive pawn]

a component of a child?

subcomponent would mean it's part a component, that's not a thing

[silver fern]

I'm in PlayerControllers and I want to get the position of ProjectileSpawner

[rich adder]

why not just make a Transform field for it and assign it

[polar acorn]

They're both part of the same prefab, so just make a serialized or public variable and drag it in

[silver fern]

oh yeah that would work

cool ty

[polar acorn]

If you have the option to drag something in you should do that

[fair nymph]

I don't see any bricks even though I moved the camera

[polar acorn]

Do they appear in the hierarchy

[silver fern]

I'd probably add a bunch of print()s to make sure all the values are what they're supposed to be

[graceful abyss]

Could someone please tell me what help file to read to make a timer to count from 0-60 over 1 minute?

[rich adder]

just substract in update or coroutine, with Time.deltaTime

there is no "help file" for a timer, there's plenty of ways you can google how to do it

[polar acorn]

Time.deltaTime is the time in seconds the last Update took to execute, so if you add that to a variable every Update, it'll be the time in seconds that has passed since you started counting

[rich adder]

float  currentTime ;
void Start() { currentTime = 60 }

void Update(){
currentTime -=  Time.deltaTime;
if(currentTime <= 0 ) //timer done```

[graceful abyss]

I meant like the scripting reference file to something that would have helped me do it but thanks guys

[rich adder]

well there is this as mentioned
https://docs.unity3d.com/ScriptReference/Time-deltaTime.html
but it has more uses than a Timer so you're asking a specific usecase that docs don't cover sometimes

[rough granite]

I doubt there is a specific one for counting from 0 to 60 (btw what nav gave is counting from 60 to 0)

[graceful abyss]

yeah I saw it, thankyou

[scarlet aspen]

Hello sorry for the dumb question, I recently started doing c# scripting on unity but honestly I was following a series that explained but was quite confusing of Kodeco... Can anyone recommend me a good youtuber to follow some videos or anything else to start learning?

[slender nymph]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[scarlet aspen]

I think the learn beginner scripting is a little bit confusing too, am I wrong?

[naive pawn]

i mean.. if you don't have any prior experience, then it is, just, a whole new thing to learn

[scarlet aspen]

You're also right...

[fierce shuttle]

If your finding the beginner scripting stuff challenging, you can try w3schools C# course or Microsoft Learn C# for Beginners, both will walk through pure C# outside an engine with terminals, topics and quizzes for you to practice the language on its own, when you feel familiar enough with the basics, going back to Unity Learn might be a bit easier

[naive pawn]

there are resources pinned in this channel as well

[scarlet aspen]

Which is complete between w3schools and microsoft learn?

[polar acorn]

You don't have to pick one

Just do both

[scarlet aspen]

Yeah why not

[fierce shuttle]

Both are "complete" in the sense that they cover all of the basics of the language, but yeah, try both out, or even some of the other resources pinned as well, any and all may be helpful to help you or explain the same thing in different ways for understanding the language

[chilly wolf]

Hello again, i'm trying to set up mouse input to switch between 3rd person perspective camera and orthographic (isometric).

scroll up for third-person
scroll down for isometric

I’m using cinemachine and i made three scripts: CameraManager, CameraRegister, and PlayerCamera. The input works, and the transition between cameras plays nicely. Weird part is that when i scroll down to switch to the isometric camera, the projection stays in perspective instead of switching to orthographic. Any idea why that might be happening?

[rich adder]

no idea whats happening without showing the code + setup

[chilly wolf]

I will show you, just a second

[hexed terrace]

Don’t know how this site works properly, but i think it’s possible to see the three scripts: https://paste.mod.gg/xbsmhpzmncbn

The camera setup in the spectator is pretty simple, tho. I have assigned the main camera with the CameraManager script and the two other cameras: "Cinemachine3rdPerson" and "CinemachineIsometric", each with the CameraRegister script. The 3rdPerson camera is in perspective, and the Isometric is in orthographic.

Edit: While looking to write this to explain to you, i found the problem (bruh). There’s an option for Mode Override in the Lens config. Anyway, I’ll show it to you anyway so you can see if it’s properly done.

I'm too lol if that's the case

[rugged beacon]

is there a way to change a graphic alpha like graphic.color.a = alpha
rather than create a new color

[rich adder]

you're just getting a copy of that value type when you access the property

[rugged beacon]

yea, just an example, want to know if there a way to do it

[polar acorn]

color = new Color(color.r, color,g, color.b, alpha)

[wintry quarry]

with an extension method you could set it up like graphic.color = graphic.color.WithAlpha(.5f); for example.

[rugged beacon]

nvm goit it

[wintry quarry]

But no there's no way to assign it without assigning the whole color

other than making a helper method

[rich adder]

getting a copy means its not the same one

[wintry quarry]

this is a very different thing than just instantly setting the alpha btw

[rugged beacon]

perhaps but this will do for now fr

[acoustic belfry]

how i can check if a 2dobject's rigidbody is still?

[grand snow]

Velocity?

I forget if it's active/sleep state can be checked or if it's reliable

[acoustic belfry]

idk, i was thinking on
rb2d.linearvelocity == vector2.zero

but i dont know if that's not very optimized

[visual fable]

zoned out and wrote an hour of spaghetti code

idk how it works so well but it sucks

[polar acorn]

Profile it and see

If you're worried about performance, profile it and check

[acoustic belfry]

ok

but in theory rb2d.linearvelocity == vector2.zero should do it, right?

[polar acorn]

Immediately I see that you should just use one overlapAll with a mask containing all of those layers and then check the layers of each thing you detect

[rich adder]

debug.log the value and see if thats acceptable or better to create a min threshold

[visual fable]

yeah probably a good idea to do, thanks for the feedback!

[acoustic belfry]

min threshold?

[eager elm]

Have fun extending that code!

[visual fable]

update one this, changed one thing, dont know what it was, and now every single item is cheese

[timber tide]

Few ideas on minimizing, your overlap check can be singled into a single check with a filter that has all of those layers. You can then iterate over the return values to compare to what they might be.

[rich adder]

yea like get the sqrMag or something, then do if(val <= minValue && val >= 0) // its stopped

Debug.Log the velocity and see what values you're getting when you think its stopped then create a variable for that as min or its a max.. however you want to think of it ig

[timber tide]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html
Would be the method with the contact filter. I'd consider this the default method you should be using anyway as you're presented with a lot more options

[eager elm]

Is there a way to add interfaces to Unity classes? Like IHasColor to SpriteRenderer and Image.

[rich adder]

nah

[teal viper]

That would require modifying an already compiled code. Which is not really legal.

[timber tide]

MYBetterSpriteRender: SpriteRender, IHasColor

No wait, wrong engine

[eager spindle]

why not inherit the class and add the interface?

public class SpriteRendererHasColor : SpriteRenderer, IHasColor {
  public bool HasColor(Color _color) => color == _color;
}

[brave shadow]

What exactly does "Layer" do differently from "Sorting Layer"?

[rich adder]

sorting 2D elements vs general layers / physics

[brave shadow]

so if Sorting Layer affects wich elements are layered on top, does that mean that Sorting Layer doesn't affect, like, collision detection and non-Sorting Layer DOES affect which objects can collide and interact?

[rich adder]

yeah for the most part Sorting Layers are for 2D visual items

[brave shadow]

thanks, that's useful information.

[ripe galleon]

does someon eknow how i could fix this error?

[ivory bobcat]

What's a pause menu?

[ripe galleon]

when you press pause

[ivory bobcat]

What is the object in the scene

[wintry quarry]

Did you attach a PlayerInput component to the pause menu object or something?

Yeeep lol

There's no reason your pause menu should have a PlayerInput component

[ripe galleon]

it´s to switsch the input, so when i press pause the player can´t do any inputs anymore

[wintry quarry]

There should be exactly one PlayerInput component in the scene per human player of the game

[ripe galleon]

it´s UI
i also have a player input

[wintry quarry]

Disable the main PlayerInput or switch to a different action map.

[wintry quarry]

I know it's UI

PlayerInput doesn't belong on it

Remove it

[ripe galleon]

sorry for writing like that, i am a beginenr so i don´t know yet how to express myself well 🙏

i will see how i can do that 🫡

[wintry quarry]

Basically this error is because it's trying to find a set of devices to assign to the new player you added to the game

It's assuming you're doing local multiplayer

Because that's the only situation in which you would have more than one PlayerInput component

[nova kite]

heyy! i'm learning state machines and im confused about something, why do we need this(1st picture) to define the functions that the state uses if we are defining them every time again in each of the actual states(2nd picture), seems redundant to me idk like why not just define them in the states only

[teal viper]

This is inheritance/polymorphism. It's important, because without this you would always need to deal with specific types. With inheritance, you can treat all the different states as their base class.

[nova kite]

but i need to treat all of them different at the base class anyway no? override them

so why declare them in the first place outside XD

[north kiln]

I'm not sure why this isn't an interface

but it's so you can pass around many objects of type State without having to know what specific sub-type they are

[teal viper]

Not in the system that processes many of these states. You don't want to write a separate state machine logic for each different state you have.

[nova kite]

but i am because i override them so technically it is specific to that state no?

[nova kite]

hmm wait so the stateMachine script would only take Enter for example? or would it be PlayerIdleState.Enter

because then again it's the specific Enter for that script

[teal viper]

Each of the inheriting types can implement different logic for the overriden methods. When state.Enter would be called, the overriden logic would be executed.

[nova kite]

ohhh i see! so only the base Method would be called but youd have to pass the correct state to override it?

like Enter(PlayerIdleState)

[north kiln]

the state machine holds onto instances of State, and it doesn't know what type of state that is because that's implementation-specific

void PerformLogic(State currentState) { ... use currentState ... }

When currentState.Enter() is called then whatever type the instance of currentState actually is will have its override called

[nova kite]

i see so you pass the state for it to execute it

ouuuu i see!

thank you both! much clearer now😄

[frigid sequoia]

This is a silly thing, but is there like any difference from calling something from inside the class than from outside of it?

Like is this a thing I should do if I am to call this over and over?

Or doesn't matter at all?

[wintry quarry]

It certainly depends exactly what "the thing" is.

There's no performance difference in terms of "outside vs inside" but if you are repeatedly accessing a property or method or series of variables or a struct, you're potentially wasting cpu cycles calling a function or copying structs.

[frigid sequoia]

So you mean like stuff that would need to be calculated on each call or what?

What do you mean with accessing a property repeatedly can waste cpu cycles?

[timber tide]

Depends if the property returns a value or a reference

Usually more of a problem if you've some giant structs of data

which is why classes are superior ;)

[frigid sequoia]

So, if the property points like to another instance of a class, that is a reference and can be an issue?

[north kiln]

1. a property is a method, calling methods incurs a cost if they haven't been inlined
2. if the property has any logic in it, then you're incurring that cost every time it's invoked

But more generally code is easier to read when you're not calling Blah.Instance multiple times in one method?

[frigid sequoia]

In some cases I do read it easier if I am reading the whole reference, cause, you know, it's pointing to a class I recognize immediately and is highlighted, not a variable I just made locally

[north kiln]

That just sounds like something you should get better naming conventions for if it's a problem for you

[frigid sequoia]

But, what properties would incur a logic to get access to? Like does it have to do with the type of the property?

[north kiln]

Sometimes singletons, especially those in Unity have all sorts of logic in their getters; surely I don't need to go through it

[frigid sequoia]

So, I should be doing this for example in case I need to reference something from a singleton many times?

[north kiln]

If you feel like that will make a difference in your scenario, then yes

[frigid sequoia]

Mmm, not sure how I can tell when that would make a difference....

[humble bay]

Hi, Im having a problem on the unity mouse lock state which is being ignored and runs further script execution

[grand snow]

then lockState must equal locked?
have you used a debugger to verify?

[humble bay]

It doesnt correctly check the lock state in editor

[grand snow]

in editor you can unlock any time with esc so perhaps it acts weirdly.
Ideally you track this state yourself (e.g. is a menu open?)

[naive pawn]

don't use deltaTime on mouse input - it's already per-frame

[latent mortar]

is this many notes necessary or overkill?

https://paste.mod.gg/

(note for every line)

[humble bay]

I can unlock ofcourse

[frosty hound]

You didn't share your code, you just shared the website.

[humble bay]

I mean when the mouse is not locked in the game and I hover it rotates my camera

[frosty hound]

And no, adding a comment to every line is unnecessary.

[humble bay]

Rotation

[latent mortar]

oh

[naive pawn]

gotta hit save first

[latent mortar]

oops

[rough granite]

Cant talk much for adding note since I've not written one in the thousands of lines of code for my game but yeah one per line is just dumb

[latent mortar]

that doesnt look right

[naive pawn]

no, not that save

the button on the website that says save

and then use the url

[latent mortar]

🤦‍♂️

right

https://paste.mod.gg/yseuxiyooedw/0

[naive pawn]

yeah ok that's way too many comments

you have more comments than code

[rough granite]

yeah at this rate it takes double the time to write the comments than to code

writing more comments than the ai does

[latent mortar]

yeah it did..

[naive pawn]

like this, this is just completely unnecessary

//sets the boolean thingy to false when function is called
i can get some of them explaining stuff, but this is pushing it

[latent mortar]

the thing with coding is that i understand alot of the functions and variables and loops etc but idk how to put them all together and make it work

[latent mortar]

yeah i lowkey started losing my mind

[naive pawn]

(also you're using both .transform and .gameObject on powerUpIndicator.
right now you have it as GameObject, so .gameObject is unnecessary.
)

[naive pawn]

yeah, that's pretty much what programming actually is, solving problems, not just telling a computer what to do

[latent mortar]

thats the hard part to know cuz no tutorials really teach you how to string things together

[naive pawn]

in general, comments are not what is being done, but why it's being done - the code should speak for itself in terms of what it's doing

[naive pawn]

right, might be because this isn't something you can learn by reading or listening - this is something you have to practice
(i'd expect some to try though, damn...)

[latent mortar]

also uhh some of the comments are a lil weird jsut sayin

[latent mortar]

yeah its usually where i get stuck

like sometimes idk if i use vector3 or transform.position etc

[naive pawn]

why would you even have this comment

//no explanation needed :////

those 2 things are.. not comparable

[latent mortar]

the first comment under IEnumerator is uhh

[latent mortar]

its a work in progress

[rough granite]

oi dont lump us all as non tryers, i spent a month (and about 5-8 hours each day) on 3 scripts that tied together

[naive pawn]

this is also just noise

//makes a variable that will be used in the function

[naive pawn]

i meant i'd expect some tutorials to try teaching the "problem solving" aspect of programming

[rough granite]

oh :/

til that class = variable (im sorry not trying to be rude just found it funny)

[naive pawn]

sounds like you're thinking in code too much for now?
you gotta figure out how you want stuff to behave first, turn that into logic, and then turn that into code

btw

collision.gameObject.GetComponent<Rigidbody>()
this can just be collision.rigidbody

[latent mortar]

Oooo I like ur way of thinking

[latent mortar]

Oh

Thats good to know

[rocky canyon]

TIL.. good tip

[foggy marten]

Weird question, but how would you return an index of the object from a multidimensional array?

[rough granite]

could you give an example of what you're asking

[sinful pollen]

yo

anyone know how to make a simple 2 d fighting game or smt?

[slender nymph]

nobody here is going to tell you anything different than what you were told in #💻┃unity-talk
use the courses on the unity !learn site like you've been instructed

:teacher: Unity Learn ↗

[sinful pollen]

alright

[lofty mirage]

If it's dimension 2, it's like arr[0][0] for 1st row, 1st col

[naive pawn]

that's an array of arrays, not a multidimentional array

also they're asking about the index, not the access

[lofty mirage]

Well multidimensional is n >= 2 no?

Here I explained for n=2

because it's the most common case

[naive pawn]

c# has different concepts for multidimensional arrays and nested arrays

multidimensional arrays would be like array[i, j]
nested arrays would be like array[i][j]

but that's still not what they asked about - they're asking about how to represent the indices

[lofty mirage]

oh yes you're right, array[i, j] instead of array[i][j] yes

[lofty mirage]

What is the type of your multidimensional array? (and how many dimensions, 2?)

[naive pawn]

bro they're asking about indices...

[rough granite]

i feel like the question would still be valid

[naive pawn]

doubt it tbh.. what else would it be other than a tuple or maybe a struct if the indices had meanings

[foggy marten]

Sorry for not responding for so long, but to answer your question - it's 2D

[rough granite]

cause if the size is small like a 2d array and it was a string so srting[,] and each value was different you could just loop through it till you have a match but if you have a huge array of ints you couldn't really cause the chances of 2 indices equaling the same number are there

[naive pawn]

i don't see how that factors in to the question at all

the part that would make a difference is this

each value was different
not the types

and honestly i don't think that part really makes a difference either

[rough granite]

what's the use case?

[eternal needle]

it doesnt make a difference what the type is. if they relied on these values being unique, their values would be unique.

[naive pawn]

just (int, int) or maybe some struct of 2 ints
maybe Vector2Int if you want to treat the array as a space - to find if stuff is in a RectInt or get Distances or stuff lol

[rough granite]

sorry what's tuple mean?

[foggy marten]

For finding and returning the object's index in a for loop

[naive pawn]

tuples are a type in c#, just a sequence of other values with optional names

[foggy marten]

I've managed to find a solution myself, but I also kinda hate it

[naive pawn]

please don't be out

[rough granite]

couldn't you use a dictionary then and find the key from the value?

[naive pawn]

not really what dicts are good at and that still doesn't solve their actual question

how do you represent the key, in that case

[rough granite]

vector2 and the value be gameobject but yeah fair

[naive pawn]

not Vector2 in this situation where they're all ints

[eternal needle]

you should share that solution then, because we don't know what you hate about it in the first place

[naive pawn]

@foggy marten just boils down to what the array represents i guess

[eternal needle]

I would start with looping through and returning a Vector2Int, i assume you're using this for some grid like structure

[wintry quarry]

Once you find the item, return the index you're looking at

[naive pawn]

(why do you assume the value would be gameobject 🤨)

[naive pawn]

context: they have a 2d array and they were originally asking about how to return the index

[rough granite]

they said objects

[naive pawn]

which is not the same as gameobject

[foggy marten]

Basically, I use a script for maze generation, where it's layout is created in a for loop, and then it creates a path by going from one cell to another, knocking down walls along the way

[rough granite]

could you provide a code snippet?

[naive pawn]

that was satisfying as hell

[eternal needle]

i meant the share the solution you talked about here. I cant imagine this is going to be much different from 2 for loops and just returning when the arr[i,j] == something

[naive pawn]

probably just Vector2Int then yeah

[foggy marten]

Can you remind me of websites where I can paste the code? I forgor, sry

That is the entire script

[naive pawn]

where's that Equals coming from

[foggy marten]

My main problem with the original code, was that it only worked properly with one type of prefab and it could not be scaled if I had a different prefab of different size (bigger or smaller)

[rough granite]

Linq i would assume

though i know i shouldn't

[eternal needle]

Object.Equals...

but ive never seen anyone use it like this lol

[rough granite]

there's no Object.

            if (Equals(cellX, mazeGrid[x, z].transform.position.x) && Equals(cellZ, mazeGrid[x, z].transform.position.z))

[foggy marten]

It's from the System library

[naive pawn]

MonoBehaviour extends Object

[slender nymph]

doesn't need it because it inherits from Object

[rough granite]

ahh i see :/

my bad

[naive pawn]

...honestly, i think you should just sit down at this point. you aren't helping

[rough granite]

nuh meanie

[naive pawn]

it will make our jobs easier

[foggy marten]

Didn't really wanna use '==' operator all the time

[naive pawn]

why? it's the same thing

[foggy marten]

dunno

[naive pawn]

if it's just stylistic preference just say that

[foggy marten]

prefrence ig? it looks neater

[naive pawn]

aight

you're doing float comparison, that might not be consistent

but also it seems like you want to do a reverse mapping, via the transform position, which is at a different scale

that's where your issue seems to be?

[foggy marten]

Kinda

[naive pawn]

instead of having to manage/translate the transform.position using the width and height into indices, just have MazeBlock remember what index it's from, so you have a proper reverse mapping

with that i don't think you'd need FindMazeBlock at all, you could just index into the array

[eternal needle]

one thing i notice is that you're doing is this
var cellX = (int)currentCell.transform.position.x;
which removes the decimal. then sending it to be compared by the original float value
mazeGrid[x, z].transform.position.x

[naive pawn]

by the way, [SerializeField] private int mazeWidth, mazeHeight = 3; only sets the default for mazeHeight.

[foggy marten]

Yeah, forgot to delete that, as I was testing the for loop with the original 1 scaled prefab

[foggy marten]

....Now I just feel dumb

[naive pawn]

you aren't dumb, you're just inexperienced

and that's way easier to fix

[eternal needle]

The value is serialized so if you see 3 in inspector, its still 3. Your default value is just 0 for maze width

Default as in when you create a new component

[foggy marten]

Huh

Though it actually set both

[naive pawn]

nah, you'd need int a = 3, b = 3; for that

it's not actually a logical issue, just pointing out that it doesn't say what you probably think it says

[foggy marten]

Would saving the index from a 2D array into a Vector2 variable be a good practice for this case?

[naive pawn]

no, because Vector2 uses floats

it could be a Vector2Int, or a tuple, or a struct, as mentioned before

there's not really a best practice, this is kind of a specific situation

[foggy marten]

I like the sound of Vector2Int - I'll go with that for now

[naive pawn]

(reasons to use a Vector2Int mentioned here - if they don't apply, then your choice doesn't matter too much)

oh also since this is just storing the index rather than having to return them as a single value, there is a 4th option of storing each dimension separately

just preference things though

[craggy depot]

Hey yall, which Ai is best for unity instructions?

I’m going insane with ChatGPT trying to make a UI

[silver fern]

Is there a way to have my bullet be able to call a method in the CharacterController script of the target that was hit without specifying the namespace?

[polar acorn]

None. !learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[polar acorn]

I'm not sure what you mean by "without specifying the namespace"

[craggy depot]

I am using unity learn, but I have a project to submit, and my pace is not fast enough 😭

[edgy pier]

AI is only good if you somewhat know what its doing.

[craggy depot]

I do have a basic idea of what it’s doing, but not complete

[polar acorn]

Then you should have started sooner

[silver fern]

I was planning on having a CharacterController script on each character that handles taking damage from the bullet, but if I have two different scripts with the same name on two different operators, it complains that the global namespace already has a definition for that script. But if I add a namespace for each one, then GetComponent() wants me to specify the namespace

[craggy depot]

Well I only got onto the project once it had already began

Is there really no way?

[polar acorn]

but if I have two different scripts with the same name on two different operators

Probably don't

If the scripts do different things, call them different things

[silver fern]

then how do I make the bullet call the method that deals damage if each character controller has a different name?

[polar acorn]

How would having two different scripts with the same name in any way solve this problem?

[rare stag]

yo

[silver fern]

I was doing hit.getComponent<CharacterController>.dealDamage(10);

in the bullet

[craggy depot]

Ok let me ask it here if it’s possible or will be difficult, so I want to make a side panel, with three different tabs, once I press on one, I want that panel to show in the same sidebar (basically switching tabs) that and when I click on something (there are tons of pieces) I want a small pop up to show what part that is

[silver fern]

hit being the hit object

[polar acorn]

This would get the CharacterController component, which, if that's the Unity component, doesn't have a dealDamage function
https://docs.unity3d.com/ScriptReference/CharacterController.html

[polar acorn]

C# is Turing-Complete. The answer to any "is it possible to" question is always "yes"

[silver fern]

oh, mine is actually called CharacterController2D, I wrote it myself

[polar acorn]

Then you would get that component

[silver fern]

and it does have that methond

[silver fern]

well thats what I did

[silver fern]

I am doing hit.getComponent<CharacterController2D>.dealDamage(10);

[polar acorn]

So if you want to ask a question about a line of code it's usually a good idea to share what the code actually is

[craggy depot]

But I mean how do I go about setting up the canvas and ui

Since for some reason, the button works once (shows the panel) but doesn’t hide it again when pressed again

[silver fern]

that is the code I just forgot to type the 2D here

[polar acorn]

Okay, so this would call dealDamage(10) on the CharacterController2D component on the hit object

[silver fern]

yes

[polar acorn]

Which changed the code into something else. There is no "Close enough" when it comes to code

[polar acorn]

so what is the problem with it

[polar acorn]

What is supposed to be doing the hiding

[silver fern]

the problem is if there are different characters each with their CharacterController2D then I have to specify a namespace

[polar acorn]

Don't make multiple scripts with the same name

[silver fern]

but then I can't do getComponent<CharacerController2D> so what do I do instead?

[polar acorn]

You wouldn't be able to do getComponent<CharacterController2D> if they did have the same name

You have to tell it which component you want

If you have multiple things with the same name you just have to specify which of those two things you want

[silver fern]

I want it to be able to deal damage regardless of which character was hit, or do I have to write a long list of if and else to check every single possible character name?

[polar acorn]

You should probably either just have the same script on both objects, or a shared parent class that contains all their shared functionality

[silver fern]

but they have separate hitpoints

so how would that work

[polar acorn]

By making that a variable?

They're still separate instances of the component

It's just the same script

[silver fern]

but they cant have the same name so how do I find that component then

[polar acorn]

They're the same script

[silver fern]

wait no

[polar acorn]

public CharacterController2D : MonoBehaviour
{
  public int hp;

  ...
}

and then put that on two objects

it's the same script

on two objects

The variable belongs to the instance

They each have their own hp

You can put the same script on multiple objects. You don't need a new copy of the code for everything that uses it

[silver fern]

well theyre not the same script so I'm trying to figure out how to solve that but thanks I think I understand the issue

[polar acorn]

If they do the same thing, they should be the same script

If they don't do the same thing, they shouldn't be named the same

If they have some shared functionality they should have a shared parent class containing that shared functionality

[rough granite]

your problem is that the button can only set the GameObject active or inactive but doesn't switch yeah? ie how when this buttom is clicked it shows a panel called Difficulty and Hides a panel called Main. But if it was pressed again it wouldn't do the opposite right.

[silver fern]

I'm trying to add a new script named TargetCharacterController and it's telling me this but class and file names all match, what gives?

[polar acorn]

Make sure that there are no compile errors and that the file name and class name match

[rough granite]

are there any compile errors?

[rough granite]

oddly enough unity has never stopped me from changing the class name and not the file name

[silver fern]

ah there was one in a different script, thanks

[polar acorn]

Unity 6 no longer needs them to match

[rough granite]

oh makes sense then :/

[polar acorn]

In older versions it would work until you restarted the editor, at which point it would break

[silver fern]

ok I have a DamageController script with the dealDamage method that is the same across all characters, while the rest is separated out into each characters separately named controller script. But let's say each character has different death animation, so I will still need some kind of way to access character specific scripts from common shared scripts, right?

[slender nymph]

use an event

[polar acorn]

Or:

• The controllers can check their DamageController to know when they run out of health
• DamageController could invoke an event that the other scripts subscribe to
• DamageController could be a parent class of the controller scripts that override the death function

[craggy depot]

YESS EXACTLY

[silver fern]

is listening for an event faster than checking the controller in Update() or does it do that anyway?

[polar acorn]

Subscribing to an event means the subscribing function will run only when that event is invoked

[silver fern]

yeah but I mean it still has to keep checking right

[polar acorn]

No

It doesn't query the event

when the event is invoked, all listeners of it will run

[silver fern]

I see, ok thanks

[rough granite]

now i know im not meant to give out the answer but well easy fix instead of using GameObject.SetActive in the button make a script like this and put it on the button and add inplace of the other stuff in OnClick and fill the GameObject with the object you are trying to change the active state of

miss spelt object 😭

@slender nymph shh, wasnt me

[covert hornet]

Hey, people.
Got some weird bug or something
When I'm logged in unity learn I can't see list of tutorials on the left in this specific tutorial.
Didn't work in incognito. Tried Chrome and Opera. Google didn't give anything useful either.
Maybe somebody encountered this problem?

https://learn.unity.com/course/programming-interactions-with-c-scripting-in-unity

[slender nymph]

this is a code channel

[rough granite]

i swear i am just too busy to explain how one would do it without just giving the answer and it seemed like no one else wanted to

[naive pawn]

this is a code channel

[rich ice]

it also has to do with #🔊┃audio

[naive pawn]

everything in unity is code under the hood. this reasoning doesn't hold

[kindred iron]

yeah right i didnt think that much

also depends how many things are on screen..genrally there is nothing worry about it to much

[craggy depot]

Ok so I tried something like this, but I used UIToolkit this time

but when i run the game it doesnt show, can you tell me where am i going wrong

[polar acorn]

I would presume it's related to the big red 🛑 on your first screenshot

[craggy depot]

ohh...😭 man unity is hella difficult (i feel so dumb)

[rich adder]

you're new but expecting to knowing something like UIToolkit isn't exactly a good place to start with

even veterans still ain't fully using an entirely new system like UITK

[craggy depot]

OMG IT FINALLY WORKED, IVE BEEN AT IT THIS FOR HOURS IT FINALLY WORKS

[rich adder]

is there a reason to use UIToolkit instead in the first place?

[craggy depot]

thanks!

[craggy depot]

yeahh it wasnt working with the canvas ugui

and honestly it DID not look good either

[rough granite]

Some how i feel like this happens every time i just give the answer :/ (no hate to you just find it funny) maybe this is why they say im not meant to "spoon feed"

[craggy depot]

haha no your input kinda helped

i got the idea of the state list because of what you said

[supple idol]

Guys I'm wondering what will be the difference between
rb.AddRelativeTorque(Vector3.forward * rotateStrength * Time.fixedDeltaTime);
and
transform.rotate(Vector3.forward * rotateStrength * Time.fixedDeltaTime);
Like I get the thing with local and global axes but codewise is there any additional difference

[naive pawn]

one goes through the rb and the other goes through the transform

[rich adder]

you shouldn't have Time.fixedDeltaTime in the rb. function

[naive pawn]

if you use an rb, you shouldn't modify the transform, because the rb is expecting to control the transform itself

it may not sync properly

[slender nymph]

also adding torque is not the same thing as just rotating by a specific number of degrees

[rough granite]

Honestly i think this is a chatgpt / ai thing cause i ngl did use ai for a short few months and this is something it would always recommend

[rich adder]

^ adding Torque is like addForce but for rotation, if you want specific rotation use MoveRotation

[candid pilot]

hi

[rich adder]

I guess. GPT has a lot of garbage stored as "relative information" so it could make sense but yeah its wrong cause rb is already moving with fixedDelta, adding it twice would not make much sense

[supple idol]

Like I'm following a tutorial and I've had previously for forward movement (a rocket and flappy bird mix) where for the thrust they've used AddrelativeForce and for the rotation they've used transform.rotate and I'm wondering why and is this the same etc.

[rough granite]

Rigidbody has physics

[rich adder]

AddrelativeForce respects forces like Damping and Friction

[rough granite]

Transform doesn't

[rich adder]

Transform is forcing it to be a specific rotation regardless of physics

[naive pawn]

well it's thinking there aren't physics

[rough granite]

Well better way of saying what i did but yeah

[naive pawn]

the "correct" approach would be to tell the rb to rotate as well

[lusty bramble]

I need help with programming animations, and getting the model out of Tpose

I have the animation files in fbx. and I added transitions. followed tutorials to try attempt to make it work but I got no luck.

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

public class Walking : MonoBehaviour
{
    private Animator mAnimator;
    private bool isCurrentlyWalking = false;

    void Start()
    {
        mAnimator = GetComponent<Animator>();
    }

    void Update()
    {
        {
            if (mAnimator != null)
            {
                bool moving = Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.D);

                if (moving)
                {
                    mAnimator.SetInteger("sn_walk_loop", 1);  // Set to walk
                }
                else
                {
                    mAnimator.SetInteger("sn_walk_loop", 0);  // Set to idle
                }
            }
        }
    }
}```

[rich adder]

if you want a similar effect to Transform.Rotate us Rb.MoveRotation at least it respects physics and interpolation but should at least not deal with outside forces like friction

[supple idol]

okay I think I get it cheers 💪

[naive pawn]

if (mAnimator != null)
you would generally want this to fail-fast, to make sure the component actually exists - but since you aren't doing that, make sure the component exists, try adding some debug logs to make sure code is being reached

[lusty bramble]

I'm not sure what you mean

still a noob

[naive pawn]

which part

[lusty bramble]

the whole thing-

[naive pawn]

you don't know what "make sure the component exists" means?

[lusty bramble]

If it helps to understand better, the animations are separate the are not apart of the character,

[lusty bramble]

nope

[rough granite]

You have an extra set of {} in the update function

[lusty bramble]

I think its the way the code is formated on discord

[naive pawn]

it technically doesn't matter (but yes it should not be there)

[naive pawn]

it is not

[rough granite]

Shouldn't the animation loop to exit or no? (I also dont use them much but was told to in the past have things end there)

[naive pawn]

not necessarily, no

[naive pawn]

do you know what components are

[lusty bramble]

I heard a lot of people say "exist" isn't needed

[lusty bramble]

Ik its related to connection in code right?

I got all of the animations here, I'm not sure if that means anything in this context

[naive pawn]

no clue what that's supposed to mean

[lusty bramble]

exit I mean

typo

[naive pawn]

each one of these is a component

if you didn't know what those were you should probably go do the unity essentials course on !learn

[lusty bramble]

Would the same logic apply to imported models that didn't come from a unity friendly file?

All these files were originally havok fiels. .anim.hkx.anim

idrk how to explain

[nova kite]

i have a basic understanding of state machines now but im having trouble deciding what should be a state and what should be combined into one state, player movement for example. he can be idle walk run jump crouch fall attack. so should each of these have a state? should each call all other states?

this seems more messy and complicated than just putting everything in one script

[naive pawn]

what same logic

[lusty bramble]

nvm

Idk how to explain so it doesn't matter

[naive pawn]

consider if it can overlap with other actions
idle, walk, run, jump, fall, can overlap with each other, but maybe not crouch or attack (depends on what actions you allow the player to take)

[nova kite]

so only overlaps should call the states they overlap with

but like should really each of these have their own state?

[craggy depot]

hey so ive setup my camera to orbit around my object, and i have put mesh colliders onto the body of my object and even added code, yet its not working, i dont even think the click is being registered. what do i do?

[naive pawn]

no, i mean if they can overlap then they probably don't need to be separate states

[naive pawn]

that's not much info to go off of. if you think the click isn't be registered, try debugging it to see if it is or not

[nova kite]

overlap in what way for example?

[naive pawn]

"running" and "jump" can coexist, thus they aren't separate states, that kind of thing
of course i don't know if they actually can in your game, just using that as an example

[nova kite]

i see so the states is not the actual movement but the logic behind it

but what if it's jumping and falling for example, because you always fall when you jump but you dont have to jump to fall

so is that coexistence or

[eternal needle]

would there be a difference between jumping and falling, other than the direction you are going?

[nova kite]

well falling should calculate if the player recives fall damage

but you dont have to jump for it

you can walk off an edge

[naive pawn]

those just.. exist separately

[nova kite]

so these are two different states

[naive pawn]

no, not necessarily

[eternal needle]

jumping could do the same, except the damage would always be 0 based on the calculations you do

[naive pawn]

it just means your jumping and falling are not coupled

[nova kite]

but then if you jump off an edge the damage would be 0

[naive pawn]

they may be part of the same state, or they may be part of different states, maybe jump is bunched in with the rest of movement and fall is a separate state

[eternal needle]

if your calculation is flawed, sure

[nova kite]

oh god XD

how should you decide then😭

[naive pawn]

my point is - just because they have separate logic doesn't mean they're separate states

[naive pawn]

can you "run" while falling?

[nova kite]

yes

[naive pawn]

then it's not a separate state

[nova kite]

then the script gets clutered and messy anyway i thought the whole point of a state machine is so it looks pretty and easy to manage

[eternal needle]

tbh i dont find theres good reasoning to separate your entire movement into states unless you need different actions to happen. Like swimming compared to walking is valid for a state
Walking, running, moving while in air are all the same thing

[naive pawn]

not necessarily?

code management isn't magically solved by putting a state machine in there

you still have to put in work to make the logic of each state work and make it maintainable

[nova kite]

i have it all in one script but it's 200 lines of code so i tried transferring the logic into states

[eternal needle]

whats wrong with 200 lines of code, you say "but" as if thats a bad thing

[naive pawn]

for example my player has, not really states, but more of actions

enum PlayerState {
    None,
    Dash,
    Attack,
    Turn,
    Stun,
    Defeat,
}

[nova kite]

if there is a bug you gotta go through 200 lines then xd

but if it was a jump state and there is a bug with jumping maybe youd have to go only through the jump state script

[rich adder]

better than monoliths of 1000s

200 lines aint shit

[nova kite]

ohh

how do you move then?

[eternal needle]

so? are you wasting time reading the using statements and lines with { or } on them? any sensible developer would try to isolate the bug to a specific section of code regardless
200 lines is nothing anyways lol

[naive pawn]

each one of those actions means you can't do a different action while it's happening (other than Stun/Defeat that override the others)
but None can transition to the others - idle, run, jump, and fall are all within the None state

[nova kite]

OHH!!

so another state should exist if you can't do it while performing any of the other states

[valid violet]

If your code base is good your won't reduce the count of lines

[naive pawn]

yes, that's what i'm trying to get at with the "overlap" thing, i mightve not explained it well

[nova kite]

you did i get it now it just didnt click haha

i see so as long as it can be performed simultaneouslyit should be in the same state

i have a rule to go by now😌

[vocal olive]

wdym you dont put a print statement at each stage to see whats going wrong 😉

[nova kite]

hold on, what about attack then in your script, you cant attack while moving?

[naive pawn]

only with one of the characters

[nova kite]

oh i see so it's intended

[eternal needle]

for basic movement, you really can get away with this all being defined in one "state". If you want to code a limitation where you cant attack while in the air, you simply check if the player is grounded, or check if its a certain enum value. You don't need to go full enterprise mode and separate this into individual classes where one state doesn't handle attacking
going back to the swimming vs running example, it would make more sense for a swimming state to exist because the logic would be entirely different

[nova kite]

but if you can attack while moving then that should be in the same script too?

[naive pawn]

case PlayerState.Attack:
    if (character == Character.Gawr) {
        goto case PlayerState.None;
    } else {
        rigidbody.velocity = Vector2.zero;
    }
    break;

[naive pawn]

this is all in the same script

my PlayerController is 400 lines long

this isn't really a state machine, i'm just using states to handle how stuff works

[nova kite]

ohh i see, so it should still have all those if statements

i guess i understood it all wrong then

i thought state machines should perform an action and then call a different action so you dont have to check if the player is doing everything he can do every frame

[naive pawn]

state machine is kind of a broad thing

hell you could probably shoehorn what i have into the definition of statemachine

[ruby python]

Really stupid knucklehead question, but could someone tell me if I'm using this correctly please? It makes sense to me but my rockets ain't moving. lol.

Rigidbody is setup correctly etc. Just can't figure out what's going on. 😕

rocketRigidBody.MovePosition(transform.position + transform.forward * rocketSpeed * Time.deltaTime);

[naive pawn]

why not set a velocity once and just forget about it

[eternal needle]

well ideally you wouldnt be checking everything every frame anyways. maybe part of that is just related to the input system you're using

[dry pewter]

When using Application.targetFrameRate if I set the target frame rate once in a game's first scene do I not have to consistently set it to that value in scenes after that or do I?

[naive pawn]

(literally fire and forget lol)

[naive pawn]

it is a global value, the value you set will persist across scenes

[dry pewter]

Okay just wanted to make sure 👍

[naive pawn]

as indicated by it being a static prop on Application

[rich adder]

Time.deltaTime not needed there

[nova kite]

well for example Input Horizontal or Input spacebar for moving and jumping, itd check every frame if one or the other or both were clicked

[ruby python]

According to the Unity Docs it is 😕

[naive pawn]

why wouldn't it be

[ruby python]

https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

[naive pawn]

there's a speed that's presumably per-second, this is presumably being executed per frame/tick

[ruby python]

FixedUpdate.

[rich adder]

thought like AddForce / Torque it was already tick moved

[naive pawn]

nah, this takes a target position

[rich adder]

oh wait thats MovePosition

[eternal needle]

you would be moving every frame in most cases, so its fine. even in air, most games allow you to move slightly. because of this you might end up having very few states that actually limit movement, like attacking could be one. This could really just be a bool like "canMove" which you check first before applying movement
it's simple enough still you dont need to separate into states

[rich adder]

I thought it was MoveRotation

[naive pawn]

wouldn't that be the same thing?

[nova kite]

then why use a state machine at all and not check if the player is swimming for example to call a swimming function within the same script

[rich adder]

hmm yeah I think, I suppose with Torque/Force you don't . nvm then lol

[nova kite]

beause you are gonna check for it anyway with an if statement

[ruby python]

I've always used Translate before, but I know that it causes issues with collision physics.

[rich adder]

nah you don't want to use Translate with physics

but just fyi MovePosition also ignores colliders

[ruby python]

Oh. lol.

[timber tide]

yeah movePosition* collision ignores walls

[ruby python]

Sorry, replied to the wrong message. lol.

[timber tide]

docs makes it sound like just a smooth alternative but tosses out the whole collision detection

[ruby python]

So, what should I be using instead to respect collisions? 😕

[rich adder]

so yea yeah typically you need to pair with Rb.SweepTest for example to consider walls

[rich adder]

.Velocity or AddForce (it cant be kinematic ofc)

[timber tide]

if you want to use non-kinematic (ye) then add force 99% of the time

Velocity I usually use for stuff like quick dash that removes forces

[rich adder]

opposite, kinematic is meant to be moved with MovePosition not addForce (kinematic dont have velocity in 3D phyx at least)

[eternal needle]

because your swimming logic would entirely be different. gravity wouldnt apply, you might be able to move up and down, you play different animations/sounds. Maybe you cant attack at all, maybe you can attack while treading the water.
Your state here would be swimming vs regular movement. Basically swapping between two classes that processes your inputs
adding these in if statements to your regular logic would make it miles more complex. its no longer just one check of a bool

[ruby python]

Yeah I was just gonna say I thought kinematic removes all movement physics.

Right okay, will give addforce a go. I think I read somewhere that you shouldn't set the velocity directly.

[rich adder]

Kinematic just means never affected by outside forces but ITself can move / push physics Dynamics objects

[timber tide]

Velocity overrides all variables you'd get from forces otherwise if you constantly set it so it's not something you should primarily use

[nova kite]

ohhh! so you have to evaluate the amount of checks you have to perform and the amount of values that change, i see so in that case that's where you seperate the logic completely

but i guess walking to running the only changes are speed and animation

so a whole new script is redundant

[rich adder]

ya setting velocity directly gives a more "snappy" feel because you're essentially overriding all other forces like Friction / Damping etc.

although unity docs always discourages from doing so

[ruby python]

hmm, okay, well velocity might be the way to go then (this is for an ffar rocket, so needs to be kinda immediate)

[rich adder]

Force.Impulse exists for a similiar effect

but yeah usually just setting vel should be plenty

[ruby python]

Just as a clarification thing, forcemode.Impulse would be the one to use if I don't want continuously adding force right?

[rich adder]

its an instant force ,doesnt mean you can't use it to apply it constant

[warm palm]

Is this a help channel?

[rich adder]

but yeah typically its used as 1 time thing like explosions and all that

[ruby python]

Right I get you. Thanks.

[timber tide]

Usually you're constantly adding forces, but impulse is a one time jump kind of situation

[rich adder]

this is a Code help channel , most channels are help channels
#🔎┃find-a-channel.

[ruby python]

Hmm......okay, now I'm really baffled, tried setting the velocity directly, but the rockets still don't move. lol.

[eternal needle]

it really is a case by case thing where yea you should evaluate how complex the logic is. the number of values isn't as much the concern but I guess it does correlate with how complex your logic might be.
Think of a door, it can be opened or closed. When it is opened, you can only close it. When it is closed, you can only open it. Ask yourself if it would be simpler to use a statemachine (+2 states, open and close) or one class with a bool isOpen? In this case its quite obvious because at the end, all you're doing is calling a function based on isOpen.

[ruby python]

rocketRigidBody.linearVelocity = new Vector3(0, 0, rocketSpeed);

[warm palm]

Perfect, I just installed Unity and used it for the first time and saw the roll a ball tutorial straight away when I opened the Unity hub, I got stuck in straight away and followed along with the web tutorial with videos but I'm getting some kind of error with the first script I've ever made "playercontroller.cs". The video says now press play and move the ball "It works!" Mine won't let me press the play button and says "Top-level statements must precede namespace and type declarations" and I have no idea what to do lol

Also I have never made a game or used any game engine in my life, or written any code for anything I'm simply a beginner level animator on Blender

[nova kite]

ooo yea! because it's just one action really and then you can do things beased on if it's true or false so no need for a whole new state

i understand it much better now thank you both!

[short hazel]

Sounds like you have some code at the top of your code which the compiler mistakes for "top-level statements"

Post your code

[warm palm]

ok

[polar acorn]

You have code outside your class

[timber tide]

Is gravity even working here? Rather is the rigidbody even responding before velocity. Maybe make yourself a new scene with a sphere and a basic rb script to test it out

[short hazel]

Your FixedUpdate is outside the class here

[polar acorn]

Yes, you have code outside the class

Can't do that

[ruby python]

I have gravity turned off.

[warm palm]

I'm so embarrassed but what does that mean?

I'm a complete noob sorry

[short hazel]

Basically the } on line 22 ends the class PlayerContoller { of line 3

[polar acorn]

The class contains everything between its { }

Your code is outside of those

[warm palm]

So just put {} around the text

[polar acorn]

The { is on line 4.
The } is on line 22.
Your fixed update function starts on line 24

[polar acorn]

No, put it in the class

[short hazel]

Move the whole FixedUpdate function so it's inside the class's { } instead

Also you'll have to set up Visual Studio because there are a few more errors in this code, and they're not highlighted right now

Well there's no need for the attitude

I'm new and I'm struggling here

If you get annoyed by helping people why are you responding

[polar acorn]

Most people are capable of reading instructions

[warm palm]

most people I've interacted with on help channels aren't cunts to people who are struggling to understand

[rough granite]

I happen to think the problem is on line 24 of whatever script this is referring to

[short hazel]

Format is (line, column), so line 24, 2nd character

[rough granite]

Yeah yeah realized after :/

And what is what i thought it was before but the fact he has a using whatever; on the 24th line seemed silly to me so i thought it could've been saying you we found an error here and here

[polar acorn]

There's no point trying to guess where the problem is when a configured IDE will literally highlight it

[short hazel]

Exactly

[rough granite]

I think you scared him away :/

[short hazel]

Yeah C# errors can't have multiple source locations, compared to some other languages with advanced analyzers
Like with Rust which tells you "hey, you can't do that here. That's because you did X on line Y. Here's what you can try instead: ..." (seriously look them up if you haven't seen them before)

[rough granite]

I can see why you didn't just point it out lol

[polar acorn]

I did.

Multiple times

That's the point

[rough granite]

I saw you talking about the lack of a configured ide which would give him the answer in half a second, which with the simple mistake he has i can agree with doing over just saying oh you are missing a space at that point

[short hazel]

Looking at it quickly there's at least 5 more errors in that file!

[warm palm]

I can't find "Windows > Package Manager" menu in the Unity Editor

If it's not too annoying for you, could you help me locate it

[short hazel]

In the menu bar, at the top of the window

File, Edit, Assets, ...., Window, Help

[sinful pollen]

is this where i ask my questions

[warm palm]

Found it, was confused because it says "Windows" on the website but just "Window" in the editor

[warm palm]

You can, but be careful some of them get triggered if you ask too many questions

[sinful pollen]

need helping dealing damage to charectors when performing an input?can anyone tell me how to?

[sinful pollen]

oh shi im ded

[warm palm]

RIght so, I already have everything installed that you told me to install

[rough granite]

Use colliders to detect it

[warm palm]

The IDE is already configured

[rough granite]

Should be a OnTriggerEnter2D

[polar acorn]

Now do you see the error underlined in red

[rough granite]

And make a collider the shape of your weapon and set it to trigger

[sinful pollen]

did but i need damage on pressing an input

[warm palm]

It was there before, did you not look at the screenshot?

[sinful pollen]

wait how do u set it to trigger?

[warm palm]

If you'd have just looked at my screenshot in the first place you would have known that

[polar acorn]

Please point to what is underlined in red in this screenshot

[rough granite]

? Then call a function whenever that input is pressed and in the function halv it deal damage, i have no clue what type of game you have

[warm palm]

@polar acorn Wrong screenshot

[sinful pollen]

dms?

[warm palm]

[short hazel]

In the code directly. The erroneous parts will have a visible red underline. That's what the configuration does

[polar acorn]

None of your IDE screenshots contain any underlined errors

[sinful pollen]

coz i think ur pretty smart and u can help me i think

[fickle plume]

Hi ! I try to make my first game, But I'm currently stuck. I'm practicing on a 2D top-down shooter, but the problem is that I can't get the character to move with the new Unity 6 inputs. When I follow a tutorial, it never works

How can i do with the new system ?

[fickle plume]

You can find tutorials pinned in #🖱️┃input-system . Follow them and if something doesn't work ask a specific question there.

[raw talon]

Thanks !

[nova kite]

when calling a parent do you have to write : base ?

is there a way where you could just write the parent's class's name or is that a c# thing

like:

class Parent
{
    public Parent(string something)
}

class Child : Parent
{
    public Child(string something) : base(something)
    {
    
    }
}

but instead do this:

 public Child(string something) : Parent(something)

[raw talon]

Actually, I'm referring to the fact that it's now an asset, but what I can't figure out is how to make it apply to an actor in the scene

[fickle plume]

The manual and tutorials in the pins explain how to use it, including the asset

[rich adder]

C# limitation

[eternal needle]

is there a reason you would want to do this? even in other languages, they use super. base is already pretty clear

[rich adder]

You could use composition or factory pattern depending what you need to do

[nova kite]

i see, no it was only for coninience to instantly know who the parent is by name when reading through the code

but i will get used to : base haha

thank you!

[rich adder]

wdym does it no show up in :Parent

cause what you showed was constructor

or you mean the base class itself

[nova kite]

i meant like being able to write

: ParentName instead of : base

but it's just a small thing i gotta get used to

[half wave]

Heyo! tiny question, what would be the best way to unzip a .zip file in unity?

[nova kite]

because this is how you do it in C++

but in c# i guess it'd be Dog : base

[polar acorn]

...no?

You need to tell it which class it's a child of

It's basically the same syntax, just without an access modifier in the parent declaration

[nova kite]

public class PlayerMoveState : State
{
    public PlayerMoveState(StateMachine stateMachine) : base(stateMachine) { }

well yea at the beginning

but then you write the : base

instead of : State again

[polar acorn]

Yeah, that's a constructor.

[rich adder]

for the constructor

[nova kite]

i dont think it's like that for C++ is it?

now im confused lol

[polar acorn]

What you showed in C++ doesn't have a constructor so I'm not sure how it handles it

[rich adder]

C# isn't C++

[nova kite]

thats what im saying

[rich adder]

yeah so don't apply C++ syntax especially to c#

they are different

[nova kite]

thats why i asked if it's possible lol

and then said it's something ill get used to

[rich adder]

except for access modifier in declared class inherited, it looks exactly the same

you mentioning a constructor which is something else

[polar acorn]

Well, looks like the reason the syntax is different from C++'s is because apparently you literally cannot call a parent constructor from the derived class

At least according to some random forum post I found

[nova kite]

ohhh that'd explain it too

because the whole thing got me confused haha i guess i havnt done it before at all

when we studied inheritence

[rich adder]

a bit of time you'll get used to its quirks lol

[timber tide]

Only large difference between c++ constructor and c# constructor is you have to also specify the parent class parameters

[grand snow]

seems in cpp the base constructor is invoked without needing to explicitly do it like in c#

[nova kite]

OHH RIGHT!!

[grand snow]

tested it out because im bored https://godbolt.org/z/e886qEoMd

[nova kite]

right!😭 omg i can sleep at night now hahaha

it instantly calls it with the correct values passed

and you can have multiple constructors and it will call the one that matches the amount of values passed or a default one

[grand snow]

ah I see. I don't do cpp enough to remember how it works tbh

[nova kite]

i only learned it cuz it's what they teach in the college computer science program haha

i hate it

[grand snow]

try rust and you may love or hate it

Its cool but sometimes soo obtuse it makes you feel like a baby learning to talk

[nova kite]

i saw the sytax at one point and i did not like that haha

[grand snow]

functional langauges can be funny but I do like the security it offers and the fact it has a real package manager and build system

before i found vcpkg i hated adding a lib to a cpp project

[nova kite]

is NavMeshAgent hard to learn? my brain is fried from all the state machine stuff i learned and the next step is making the enemy and it says enemies in games mostly use that thing

[ivory bobcat]

This is the beginner coding channel

[lusty bramble]

oh-

well

I'm also a beginner following off of the main Unity tut

[rich adder]

its not hard to learn for what it does, its pretty easy to use considering its doing complex RVO avoidance and A*

[ivory bobcat]

If you're not asking a question about code, you may want to try the other channels.
For general purposes, probably #💻┃unity-talk
For your specific animation question, probably #🏃┃animation

[lusty bramble]

okay

[timber tide]

Unfortunately Unity's avoidance is pretty bad

Otherwise dumb swarm logic it works fine

[rich adder]

some tricks you can use to mitigate some of the problems

[timber tide]

https://cdn.discordapp.com/attachments/288887968960086016/1343784806605131827/Unity_MUDtAzhKWk.mp4
Pretty much the extent of the avoidance

[rich adder]

never seen 2D isn't that third party?

[timber tide]

2.5D

I cheat

[rich adder]

that twitchy movement is strange never seen that b4 lol

for a group of enemies I usually don't assign the same target, i try to give unique ones that are aprox near it

[timber tide]

their agent zone is rather large, but shows what happens when there's no gaps to really pass through they just spaz out

it works fine for a small number of units but it'll eventually start vibrating with enough agents crammed together

[rich adder]

yeah sometimes if they are on the same narrow path they do weird behavior but you also need to play around with the avoidancePriority number

[timber tide]

it's also quite expensive, rather exponential the more units that are close. A* project has a few better ways it handles it which is why I consider a must buy ;)

[teal viper]

That would definitely not be a valid syntax in C++ either.
: State(param){} would work.

[quiet hazel]

Hey guys, quick question here, how do you do a save and load, continue progress thing? I don't know nothing about anything, any Youtube videos I watch don't really help me.

[timber tide]

JSON serialization and deserialization

[quiet hazel]

I've tried that, it didn't work

[rich adder]

show what you tried
