[swift crag]

no, this is also very wrong

that's not an array of Vector3

[polar acorn]

You should probably look up how to make a list instead of guessing and waiting for us to tell you the guess is right

[timid oriole]

true

okay thanks guys

[ivory bobcat]

In C# the square brackets would be aligned with (next to) the type rather than the name.

[remote osprey]

@swift crag ?

[swift crag]

The individual components can subscribe and unsubscribe

But you can also have the input manager decide whether or not to call methods, yes

[ivory bobcat]

The usual choices are (assuming every object being polled needs to be polled):

• individual polling: straight forward and easy to perceive what is happening/not-happening
• events: subscription based, where you're able to flexibly change whether or not objects should continue to be polled.
  It's simply a design choice - you'd have to write (create) some sort of state base manager if you're wanting to later add removable polls as a feature.

It's a preference (other than doing more than simply polling)

[torn vapor]

i think ive run into a unity bug, i pressed the visibility icon on the object, but it doesnt get hidden, in fact no object gets hidden. Do you guys know how to fix this?

[ivory bobcat]

Unity’s scene visibility controls allow you to quickly hide and display GameObjects in the Scene view without changing their in-game visibility.
https://docs.unity3d.com/Manual/SceneVisibility.html
Would that be the scene view?

[torn vapor]

yuyp yup

its scene view

[ivory bobcat]

Maybe hit the toggle up top in the scene view

[torn vapor]

oh lol

didn't realise that was an option

well that was silly

[strange prawn]

Im having issues with unity/unity hub, I was working on something until I got an error saying " Assertion failed on expression: 'res == EAGAIN II !HasAbortingErrors()’ ”, I deleted unity hub & unity editor, deleted the unity file out of my finder, reinstalled unity 2019.4.31f1, the iOs support & android package & I opened unity hub, added the package back to my projects tried opening it to reimport it all, everything is gone when I open it & I closed unity, went back to unity hub & tried to fix the manifest.json but it didnt work, it keeps telling me that theres an error with the indepence named accessibility that's stopping all my imports from importing & im still getting an error that says: "Assertion failed on expression: 'res == EAGAIN II !HasAbortingErrors()'" how do I fix both of these?

[teal viper]

Also, I'm not sure what that manifest is supposed to explain?

[strange prawn]

this is what happened after i tried clicking continue & reimporting everything

[teal viper]

For starters, move your project out of the users folder.

[timid oriole]

Just an update you guys I got it working was very simple didn't have to use lists luckily https://gdl.space/lihizoxido.cs

[strange prawn]

Thats where my projects are normally saved though, won't that affect the folder?

[teal viper]

You should normally avoid putting complex development projects in the user directory. Since different access rights can affect it.

[strange prawn]

Oh okay. I moved it to my documents folder, what do I do now?

[teal viper]

Documents is still under the users directory

Move it to the disk root or somewhere nearby.

[strange prawn]

I moved it to the desktop instead since the only other options are applications & downloads

[queen adder]

is it acceptable to project scale make void Reset a [Conditional("UnityEditor")]?

[teal viper]

No. Desktop is under users folder as well... Can you not move it to the disk root as I suggested?

[strange prawn]

A disk root?

Im not sure where to find that..

[wintry quarry]

If your desktop is at C:\Users\scarred\Desktop The disk root is just C:\

[summer stump]

Because you can make folders, there are many many more options than that.

[subtle orbit]

I need help where do I go from here

[wintry quarry]

what are you trying to do

[subtle orbit]

Make a game

I am new

[summer stump]

Use screenshots, not pictures of your screen, and describe the issue

[wintry quarry]

open unity hub on your computer and make or open a project

[subtle orbit]

Ok

[subtle orbit]

Then where

[summer stump]

What do you mean "then where"
That is the end.

You make or open the project, then... make the game

[summer stump]

There is a lot to do after that of course, so it is hard to say anything specific

[summer stump]

Use screenshots, not pictures of your screen

[wintry quarry]

you have to open unity hub

that was my first instruction

[subtle orbit]

This

[wintry quarry]

https://unity.com/download

[summer stump]

To be clear, none of this is to be done on any website

[summer stump]

Stop

[wintry quarry]

well - downloading the hub is on a website

after that, no websites

[summer stump]

Ah yeah, thought they had it already. True true

[subtle orbit]

Ok done

[wintry quarry]

Follow the steps

after you install the hub, open it

insstall the latest editor version

then click to create a project

[strange prawn]

Here?

It won't let me move it there...

Unless I put it under system or another folder.

[wheat wave]

there's no way unity can run on a chromebook

[wintry quarry]

didnt realize they're on a chromebook

[summer stump]

I do not use mac, but can you put a folder there and use that?

[summer stump]

I guess it WAS a good thing they posted that terrible photo haha

[strange prawn]

Nope, it still wont let me

[queen adder]

is it just me, or there really isnt a docs for this attribute

[slender nymph]

it is undocumented

[queen adder]

hope it works tho, this code of mine is dependent on it :3

everything dependent on OnENable, and dont wanna make a mini coroutine/delayedcall pattern to call them

[slender nymph]

it does work, all it does is set a default order for the script execution order for that type

[ruby ember]

anyone know how to make transform to poses

first video is my project

second video is an example of how i want it

[slender nymph]

animate it?

[ruby ember]

i mean rotate smoothly

[slender nymph]

slerp the rotation

[ruby ember]

i added animation when you click a button but it dosen't rotate smoothly it just like clips something like that

[slender nymph]

you don't need to animate the rotation, that doesn't actually make much sense. just keep track of the target rotation and slerp to it

[ruby ember]

i know i don't need to animate the rotation

[slender nymph]

then why did you?

[summer stump]

slerp the rotation

[ruby ember]

look

the thing is that when i click a button but when you rotate a different direction it plays but it needs to rotate the pose as it needs to be as the animation

just watch the second video

[slender nymph]

what do you mean by that

[ruby ember]

watch the 2 videos

you might understand

[slender nymph]

i did. i still don't understand the issue you are experiencing because you refuse to actually describe what is happening in a way that makes any fucking sense

[ruby ember]

the second video

the animation rotation start is in front like Y90

but when you rotate the camera to like Y120

and when you press a button or something the camera forces to rotate to Y90

[queen adder]

is there a way to select a preset here via code?

do have to manual each?

[slender nymph]

again, if this is all about rotating an object, you do not need to animate it. just slerp its rotation

[ruby ember]

and how do i slerp rotation

that's why im asking because i never did this and i need help

[slender nymph]

you start by googling "unity slerp rotation"

[ruby ember]

bruh this is no help

fine

[slender nymph]

you are required to put effort into your issue or you won't get it fixed. i am not about to do the work for you

[queen adder]

can we do this wothout custom editor?

or hopefully an attributed string that I can use to any other script

[summer stump]

You were given direction. That is the kind of help you get here. If, after you put in effort and learn a bit, you can come back and show what you tried and we can guide you more from there.

Slerping is definitely the right choice for this. It was a good direction

[slender nymph]

this is not something that is built in, you'd have to use a custom editor or some asset that does it

[summer stump]

Specifically the black outlined part?

[queen adder]

just as long as there's a text that the user will laways see

probably clean as well (for presentation purposes)

[verbal dome]

Header attribute is the closest that comes to mind

[queen adder]

hmmm.. that is quite a little acceptable maybe

actually, I can try to make an asset of it

with a prop drawer

aight imma do that Ig

[slender nymph]

should be pretty trivial to create something like that using a decorator drawer

[queen adder]

oooh what's that

fiest time heard of

[slender nymph]

property drawer is for drawing properties, decorator drawer is similar it draws information or other decorations. the Header attribute is an example of one

[queen adder]

Im currently leaning to make it likecs public DisplayString xsd123 = "This is a tutorial covered by a box"; is that deco drawer better than prop drawer?

[slender nymph]

it's not "better", it accomplishes a similar, but different, function. and you wouldn't need extra data in your class, just an attribute attached to a field and the string can be passed to the attribute's ctor instead of being stored as part of the class

https://docs.unity3d.com/2017.4/Documentation/ScriptReference/DecoratorDrawer.html

[queen adder]

hmm, imma go with prop on this one ig, it will be more versatile for the purpose(as it can be placed on classes that dont have fields), can turn it into a conditional compilation to not hurt runtime if that's just the drawback

thanksuu

[slender nymph]

can be placed on classes that dont have fields
how though because you have to create a field for it

[queen adder]

I was describing a propdrawer there

ah i get it

yea, but it doesnt directly require you to make something else

[slender nymph]

then where is the display string coming from if not from "something else"

[queen adder]

prop vs decor?

[slender nymph]

also why would you have inspector documentation for something that doesn't have anything in its inspector anyway? that's what normal documentation is for

[queen adder]

basically a small text explaining what the thing can do :>

like notes thingy

ohhh can a class be decorated? Rather than fields?

if it can it would be like better

[slender nymph]

yes i understand what the point of the tutorial text you are trying to create is for. but why would it be on something that has nothing at all in its inspector?
if it has nothing in the inspector at all its documentation would preferably be with the rest of your actual documentation and not require someone to stumble across the component and add it to an object just to find out what it is

[queen adder]

some of my components just needs to be attached and will do it's job automatically on certain callbacks

just extra ways to tell peeps what things can do cause my naming skills is bad

[slender nymph]

right so your actual documentation that you ship with the asset should contain that info

[queen adder]

is that enuff tho?

[verbal dome]

Your inspectors could have links to the doc

Like a small "?" Button

[slender nymph]

i mean theoretically yes. but it's your project, do what you want 🤷‍♂️

[ivory bobcat]

I wouldn't want to have to randomly add components to see what each component does.

[queen adder]

quite insecure my inspector is ugly, figured imma add just extra stuff to .... make it look a little detailed

[ivory bobcat]

A lookup document would suffice and be preferable.

[slender nymph]

this already exists! they just need to use the HelpURL attribute

[verbal dome]

Nice

[queen adder]

aight

[slender nymph]

this is not an example of the type of component i was referring to. this has stuff that needs to be configured in the inspector so having some text explaining it there would be helpful to supplement the documentation (but not replace it)
i was referring to a component that has no fields since your complaint about the decorator drawer was specifically the need to add a field to that class for that purpose, which i pointed out was what you were required to do for the property drawer anyway

[final plover]

is there any way to make a script update faster or something? Basically i have little smoke sprites that appear as "trail" behind the missile. At slow speeds it works nicely but at high speeds it barely shows and theres massive gaps. Any ideas?

[slender nymph]

Update runs every frame already. that's about as fast as updating a component will go. it seems like there may be some issue with whatever logic you use to do that

[spare mountain]

you're moving too far in a single iteration

most likely

[final plover]

okay. I think i need to limit the linear velocity tbh. The missile controls feel fine until it gets going real fast. It doesnt feel like theres enough drag or resistance (i havent taken physics yet idk the term)

[verbal dome]

You would have to spawn more of them between the last and current frame's position, relative to the distance traveled

If you'd use the particle system then it would handle it for you, theres a 'Rate over distance' setting

[final plover]

Ok i'll have to see what i can do with it. Thank you

[timber tide]

havent looked into the PS but the problem is you need some linear interpolation

vfx graph I do some of that as it'll leave gaps for those quicker projectiles

[sage escarp]

hi guys, i can't create a prefab variant of this prefab cause the option isnt in the menu.. i followed the docs... but i dunno why its not showing up

[timber tide]

drag it on the scene, rename it then drag it back into assets

[chrome shadow]

what does "static" in scripting mean?

[eternal needle]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/static
makes stuff associated with the type rather than an instance

[queen adder]

did unity provide a code for these presets? Manually writing them by code is grindy

[strange prawn]

What should I do now since I can't?..

[ivory bobcat]

There are many who manually wrote them, for example https://discussions.unity.com/t/solution-set-ui-recttransform-anchor-presets-from-code-c/170367

[queen adder]

id call a foul on unity for this one

why not make an accessible codes/api for it when it is already written

it looks nice tho, thanks for these (and the author)

[charred spoke]

Like every piece of software Unity is no where near perfect. You can make a suggestion on the public roadmap.

This probably falls in the category of not worth supporting since people can bang it out in 20 mins for their own projects

[dreamy relic]

Hey,

I'm trying to implement moving my character using the CharacterController. I have the same code from https://docs.unity3d.com/ScriptReference/CharacterController.Move.html) and it works.

But now I want my character to be always facing in one direction (to the front), but when I click 'a' or 'd' to move it to the left o right, it start facing those directions. I'm a bit stuck on how to achieve this while using ´controller.move´

[slender nymph]

please see #854851968446365696 for what to include when asking for help. you haven't actually specified what part of that you are struggling with nor have you provided relevant code

[woven holly]

why when i add this line of code does it randomly start giving me the error: "'Random' is an ambiguous reference between 'UnityEngine.Random' and 'System.Random'"

also idk if im even doing that right i just looked it up

but when i remove that line of code my Random.range(x,x) works fine

[slender nymph]

https://unity.huh.how/compiler-errors/cs0104

[cosmic dagger]

because you did not specify which namespace you are accessing Random from. both UnityEngine and System have a Random class. you need to specify which Random class you are using . . .

[charred spoke]

‘’’if (move != Vector3.zero)
{
gameObject.transform.forward = move;
}’’’ this piece of code turns your character in the direction of movement

[woven holly]

okay how do i specify?

[slender nymph]

#💻┃code-beginner message

[woven holly]

oh my bad i see now

[cosmic dagger]

by using the fully qualified name. refere to what boxfriend mentioned: <#💻┃code-beginner message> . . .

[woven holly]

So why does it give me the error only when i type that line of code? is it because I dont use one of the namespaces until i reference Convert or smth like that?

and then it starts using it?

[slender nymph]

Convert is a class in the System namespace

https://learn.microsoft.com/en-us/dotnet/api/system.convert?view=net-8.0

[woven holly]

so i must not use anything in the System namespace until now then?

[slender nymph]

did you not bother reading the link i sent?

[cosmic dagger]

i'm not sure why you're using Convert in the first place . . .

[chrome shadow]

Ty

[woven holly]

Because im a beginner and idk what im doing so i googled it and that was the top result

[woven holly]

I dont see the answer to my question

[slender nymph]

ah wait, i think i misunderstood this message. you are very likely not using anything else that requires importing the System namespace

but like i said, the Convert class is in that namespace, although i don't really see the need for the Convert.ToInt32 call here, just cast

[woven holly]

okay so when i use convert then it starts calling system and thats when it sees two versions of Random, yes?

im trying to understand how the code works as well as fix it

[slender nymph]

it's not "calling" System. you've added the using statement for the System namespace so now it sees those two Random types with conflicting names. this part is all spelled out in that link i sent

[woven holly]

the using statement has been there since the start

[cosmic dagger]

when you use Convert, your IDE adds the using System; namespace to your script. this gives you the conflict with System.Random and UnityEngine.Random . . .

[slender nymph]

not the System one. that is not is not included in unity's MonoBehaviour class template

[woven holly]

ohhhh

it added it for me? i did not know it did that

[slender nymph]

yes, when you autocompleted the type name for Convert

[woven holly]

i see now, thank you

[woven holly]

do you have a better suggestion for what im doing? im trying to round down to nearest whole number if its not clear

[slender nymph]

Mathf.FloorToInt

or just cast the result of the Math.Floor call to int using (int) which is literally what Mathf.FloorToInt does anyway

[edgy needle]

Do i need mac to export my game to macOS?

[charred spoke]

Yes

[hasty sleet]

Idk, it's probably more about the utility more than time cost. You can add gravity in a few lines of code, but "UseGravity" was added as a toggle to rigidbody components since it's useful despite it being easy.

[cosmic dagger]

you'd only add the namespace to your script if you are accessing many methods from within that namespace. this is easier than using the fully qualified name, like UnityEngine.Rigidbody or UnityEngine.Transform every time you want to declare a variable . . .

[woven holly]

oh okay so i can call the namespace without the Using script?

[cosmic dagger]

you can use an explicit cast to an int with (int) or use a method from the Mathf. library . . .

[slender nymph]

this message makes very little sense

[hasty sleet]

You can reference modules by referencing the entire namespace. The using keyword is a convenience.

[charred spoke]

I would say adding gravity to a closed component such as the rigidbody is much more difficult

[woven holly]

yea this is what I was asking

[charred spoke]

Again no piece of software is API complete so just deal with it

🤷‍♂️

[edgy needle]

even for iOS export cuz i dont have an android?

[hasty sleet]

That's a bold statement

Embrace change and improvements, yes?

I like this philosophy more.

[charred spoke]

Yes. You need XCode to build to mac and iOS you also need a pple dev account and pay $100 per year for it

[eternal needle]

You do know unity is changing, and updating like every 2 weeks

[hasty sleet]

Sure, never said it wasn't

[cosmic dagger]

i believe you mean, you can access a class or function by using its fully qualified name (inlcuding the namespace). . . .

[edgy needle]

damn lol

[hasty sleet]

"Just deal with it" is not quite helpful and not very empowering

[charred spoke]

I also find it dumb that this api is missing yes. Like a said it warrants a suggestion on the public roadmap

[woven holly]

without typing "Using namespace" first is my question

but Travis answered

[cosmic dagger]

this is how you can start separating your code into modules for reusability and modularity . . .

[cosmic dagger]

yes, i figured that's what you meant . . .

[slender nymph]

i just want to point out that you should be able to build a mono application for macOS on windows. afaik it's just il2cpp that will require the mac to build.
also notarizing the build requires a mac but that is technically a separate step from building

[iron wing]

if im understanding this right, is it possible to get a specific axis from a vector3 variable?
for instance. i have the variable 0.00, 0.00, 0.50 can I get only the z value from this variable? or the third, 0.50 value. im still trying to wrap my head around this, sorry if im asking stuff weirdly

[slender nymph]

check the docs

[charred spoke]

I dont think so. Last time I checked “building to mac” outputs a xcode project regardless of mono or il2cpp

[hasty sleet]

Yes, a Vector3's three numbers are accessible as properties.

Vector3 myVector = new Vector3(0.00, 0.00, 0.50) can be accessed through myVector.x, myVector.y, and myVector.z for the three numbers.

myVector.z would return 0.50 in this case.

[slender nymph]

there's a toggleable option to create an xcode project

[edgy needle]

does anyone here runs linux to test my game?

[slender nymph]

if you want people to test your game then post in #1180170818983051344 with a link to a reputable host site (like itch.io)

[edgy needle]

ooh okay

[mild lake]

Hey! i'm making a pretty simple character system and i just wanted some advice. So far I've made a simple character class, and a couple other classes that inheriet from it, and set some basic data. How can I make a list of these inherited classes to choose between? Or does anyone have any better ideas on how to create a better frame work for handling data like that.

At the moment i'm setting a bunch of basic stats, like health, move speed, ect, then i'm trying to assign the class to the player, read the information off the class, and use it accordingly

[raw token]

Sounds to me like a job for Scriptable Objects 🦸

[hasty sleet]

My immediate hunch is that inheritance might be inferior to composition here. Unity's primary architecture is Entity-Component System. Most of my early choices to use inheritance have been rewritten to use scriptable objects or just scripts

If you put serialized fields in your scripts, you can set these values from the inspector. If you want to pre-set them, you can use prefabs, and if you want to store configuration in a script, then consider using scriptable objects

[mild lake]

hmm.. Scriptable Objects seemed awesome for the more primative data, but i'd also like each class to have functions written into it that can be ran. For instance, if the player pressed f, it would pull the function from the child class and then run it. Can i do something like that with scriptable objects?

I'm coming over from lua so i have an odd way of thinking about C# lol

[hasty sleet]

I would make the PlayerController script hook up the logic in its OnEnable function such that OnPlayerPressedF --> DoTheActionOnF

[mild lake]

It's not the performing of the action i'm stuck on exactly, moreso how the function will be accessed to be ran

[hasty sleet]

Composition is a fine way to do this. The script can access another component OtherController and run a function stored in another script

It is hard to give specifics without a clearer understanding of your intended architecture / outcomes

The main question that needs to be answered is: What outcome should this have? Phrase it in terms of a use case, like "A player should be able to", and it will be clearer for me

[mild lake]

I'm trying to make a framework (for a lack of a better word) that has inputs for basic information such as health,speed,attack,ect and then more complex information like functions (onAttack, onSpecial, onDeath) and then i'd like to use this framework to make classes that fill in these blanks to be used. Once my classes are done, i'd like to make some sort of handler script to read the data off the class, then process it. So again, if the player pressed "F" it would read the function onSpecial() from the child class, and then perform it

That's just the idea in my brain though, i don't know how feasible it is

[hasty sleet]

The logic is 100% feasible, but implementation methodology is critical

So I'll explain how my architecture works, and you can see if this makes sense to you:

PlayerStats --> Mostly a data container.

PlayerHealthController --> PlayerDeathHandler
PlayerInputController --> PlayerMovementController
                     \--> PlayerInputController

PlayerUIController (Handles input and routes it to UI actions)

(Input) <--> (Affect Change) <--> (Store Data)
InventoryView <--> InventoryController <--> InventoryModel

It is not perfect and may become more organized as time goes on, but there is a clear separation between components.

[mild lake]

What do the arrows represent?

[hasty sleet]

If you want HealthController to be able to invoke a Death mechanic, you can store it in another script, and when HealthController's Health goes below 0, it can call a method in PlayerDeathHandler, or emit an event that PlayerDeathHandler listens to

The arrows represent the flow of input and action, just like you wanted to direct the flow between player input (pressing F) and action (movement, UI interaction, etc.)

In terms of storing data, you should do this with scripts that are intended to store data. In my example, it is the InventoryModel which is entirely focused on storing data, while InventoryController is focused on changing data

If it helps to break down the logic further, here's what one of the child classes looks like

public class DefaultClass : PlayerClass
{
    public DefaultClass()
    {
        className = "Default";
        health = new HealthSystem(150);
        speed = 5.0f;
        jumpHeight = 2.0f;
    }

    {
        Debug.Log("Playing default class");

[hasty sleet]

The fact that this doesn't inherit from Monobehaviour is probably a problem

I think it might be best to embrace the ECS architecture and turn this into a data class instead.

public class PlayerStats : Monobehaviour
{
  public string name = "Default"
  public int health = 150;
  public float speed = 5.0f;
  public float jumpHeight = 2.0f;
}

public class PlayerInputHandler : Monobehaviour
{
  private PlayerControls playerControls;
  private AbilityController abilityController;

  private void Start()
  {
    abilityController = GetComponent<AbilityController>();
    if (!abilityController)
    {
      Debug.LogError("No ability controller found.");
      return;
    }
  }

  private void OnEnable()
  {
    playerControls.Player.UseAbility.performed += UseAbility;
  }

  private void UseAbility()
  {
    Debug.Log("aaaa I'm using an ability");
    // Or, alternatively
    abilityController.UseAbility();
  }
}

Does this make sense?

[mild lake]

PlayerStats is the only thing confusing me, because i'm still thinking about how different classes would have different stats. Everything in PlayerInputHandler i understand very clearly

[hasty sleet]

I actually have my stats separated by class, too. I clumped them together for example

I have my JumpHeight and Speed in my MovementController
I have my Health in my HealthController
I have Strength, Dexterity, Constitution, etc. in my StatsModel.

And they communicate with one another by reading each other's data

[mild lake]

For ease of access and creation, I'm trying to have all of the classes stats, functions, you name it in simple place. In lua i had one massive keyed table, with other tables inside it, holding the type of data i was mentioning. Then i'd just go to that key in the array and pull the function when i needed to run it. So i could simpy type [Classname].function() to execute an ability

I don't know if that's possible with c#, or even something close, but that's what i'm trying to recreate

[hasty sleet]

This is an anti-pattern called a GodObject

It's possible, but your class will grow to multiple hundreds of lines long and you're going to wish you separated them

if you want to put thousands of lines in one script file, then be my guest, but separating them is considered good for modularity.

[mild lake]

I was getting pretty worried about the massive scale, which is why i'm now trying to split them into sub classes/children of a base class

[mild lake]

I absolutely agree

[hasty sleet]

I would advise against using subclasses by default

While you can use inheritance, I think it's the wrong tool most of the time in Unity

The architecture is ECS, Entity-Component System, where components are scripts, the glue that holds everything together. If you use inheritance, things can get complicated and tightly coupled very quickly.

There's a saying, "Prefer composition over inheritance"

A script is a component, so it's preferable to inheritance.

What you appear to be doing is accomplishing ECS but through extra steps via inheritance

[mild lake]

Hmm, i am pretty new to coding as whole. I've done it for a very long time, but i never delved into the truly serious side of things. Do you have any resources to further teach what you're describing?

[hasty sleet]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[hasty sleet]

This is solid for Unity in general

But if you want to touch on the theory-side of coding, it is quite complex, so I recommend starting off with tailored questions when you search for answers.

The Wikipedia article is decent: https://en.wikipedia.org/wiki/Entity_component_system

The #1 way to learn, however, is simply to build.

Start off small and build a movement system. Then build a health system. Then build an enemy that just flies at you. Make the enemy damage you. Etc. Keep adding on and building things, and the principles will make more sense once you have the experience to understand the meaning behind them

[mild lake]

I know it's sub optimal, but i'm super motivated right now and running over the basics again kinda sucks the life out of coding, so i'm more so tacking the issues i face head on

And i have the movement and health system currently, i'm trying to set their variables

[hasty sleet]

I think you are in a tunnel right now, and if you just take one step back and pick a different path, you will still be stuck in the tunnel. I highly highly highly recommend you just do things the "Unity way" and accomplish your objectives this way.

You are doing things the OOP way instead of the ECS way.

I don't think you'll make it far if you try to headstrong pure OOP into Unity

I did the same thing when I started and I regret it

It won't take longer than 20 minutes if you just follow a tutorial to get the basics up and running and take it from there.

[fossil drum]

If you like ECS, why don't you use #1062393052863414313, that uses ECS in Unity?

[hasty sleet]

I never looked into it

Plus, my project is deeply in progress. I might consider pivoting if I finish my current one

[mild lake]

I'll give it a run by

[eternal needle]

Do you mean different numbers for the stats, or like actual different stats where some things may have X while others dont?
Id really just go with 1 stats class, regardless of if the character is using every single stat. Scriptable objects is a really good way of plugging in different numbers, instead of the example class you showed above. It would just copy values from an SO, suddenly everyones different stats can be represented by an asset in your folder.

[mental aspen]

When I build game, suddenly some changes appear in these files:
URP-HighFidelity.asset
BurstAotSettings_StandaloneWindows.json
CommonBurstAotSettings.json

It occurs everytime I build a game. Should I commit these changes?

[fossil drum]

Hmm, personally I dislike suggesting ECS for the normal monobehavior way that Unity works with.
Either work OOP in normal Unity, or ECS in DOTS.

[hasty sleet]

Monobehaviors is ECS, for the most part

I think you should not default to inheritance in Unity scripts.

[mild lake]

I'll be honestly, this all sounds quite out of my league. I'm by no means new but I'm pretty lost as to what most of this means haha. ECS seems preferable, but i don't think i have the means of skill to delve into it just yet

[eternal needle]

i think you are just taking the name "ECS" and applying it to something for what you think it is. ECS is a completely different workflow and really you said you never looked into it...

[hasty sleet]

I suppose technically it would be GameObject-Component

I didn't look into DOTS ECS but components for composition is the essence of default Unity

OOP is certainly not the default design pattern

[eternal needle]

i definitely do not suggest actual ECS. theres is a major difference between composition and ECS. To put it in simple terms, composition is like "attaching scripts to an object, if it has the script, it can do this functionality". Inheritance is more "I have 1 script, i derive classes to give it unique functionality". Both have their use cases of when it is preferrable

[hasty sleet]

Retroactively consider my mentions of "ECS" to be "Composition over inheritance"

Google is telling me it's GameObject-Component by default, which seems reasonable

[mild lake]

Just so i can get a better grasp, could you apply this to the situation i'm in right now?

[hasty sleet]

@eternal needle

[mild lake]

Specfically regarding an interger number, and a function of sorts

To mean, it sounds like the "abilities" i'm trying to make in ECS would be individual classes, but i feel like i missunderstood

[hasty sleet]

You don't necessarily need ability to be a class; it can be a function. My recommenation was to put abilities into a separate class if you plan on swapping them between PlayerControllers, and then simply swapping the mapping between the PlayerController and AbilityManager class, or what have you

[mild lake]

I did suffer from a few issues in Lua, with my god object. For instance, adding anything to the massive array would require me recode a lot of stuff, and every class needed to have the same inputs, so it wasn't very flexible. I assume i'd have similar issues with class inheritance

try not to cringe coder edition haha. I mean it worked, and i was just goofing off in a multiplayer game me and my buddies played, so it served it's purpose

[eternal needle]

For a character system, i really wouldnt inherit at all. Everything about a character is really just unique functionality you can attach to an object. Like for movement, theres probably some standard things you can do. Lets say, move jump and knockback. The character itself shouldnt implement this, it should just reference another component that does it. This would be composition, you attach a movement script logic to your character. Things may be able to call like
character.ApplyKnockback(whatever) and then the character script could apply that to its movement script. The movement script itself could use inheritance. Lets say things want to move in different ways, one character flies and another cant. Either way the functions are the same, move jump and knockback. Jump in this case might just be going higher while flying

Even the stats system you dont need inheritance, the character script can just hold a reference to the stats. The stats can get all of its information from scriptable objects

I like to make my code in a way where i can fully define an enemy in editor. Excluding the need for unique abilities of course

[astral falcon]

and even unique abilities could be tailored into that system if built up carefully

[mild lake]

Seems like we're on the same page then. I pretty much have everything besides the most basic stats separated into unique classes "playermovement, healthsystem, playermanager, playerclass(parent), defaultclass(child). The player manager assigns the class, and the player movement refrences that assigned class for it's speed stats. That's the way I'm currently trying to make it at least

I already had scriptable objects set up too, the only reason i didn't use it was because i couldn't add the unique code

[astral falcon]

Why do you have a default class inheritance for your playerclass? Your player should be your players base.

[mild lake]

i don't understand, player?

[eternal needle]

i just meant more of an ability is gonna have to require a new script if its really specific. Unless you really go deep into making a modular system which isnt easy. I guess it is still defining an enemy in editor but theres still one script only used for 1 thing.

[hasty sleet]

For context, WendigoJr is used to using Lua and is not familiar with Unity's style of doing things, so they're coming from a pure OOP perspective

[astral falcon]

Nothing wrong with OOP being used in unity

So what is playerclass doing, what is playermanager doing?

[hasty sleet]

Never said it was. It's just not a good default approach for their use case.

[eternal needle]

meh it still is OOP, just we are defining instances of objects in editor vs defining it in code.

[mild lake]

public abstract class PlayerClass : MonoBehaviour
{
    public string className;
    public HealthSystem health;
    public float speed;
    public float jumpHeight;
    public GameObject playerModel;
    public System.Action ability;
    public System.Action onDeath;
    public bool canUseAbility;
    public float abilityCooldown; // Cooldown time in seconds

    public virtual void Start()
    {
        health = new HealthSystem(5); // Default max health
        canUseAbility = true;
    }

    public abstract void UseAbility();
}

[hasty sleet]

Eh, I guess that's accurate

Weird to think of that as the "object"

[astral falcon]

And what is defaultclass doing that you need to inherit?

[mild lake]

public class DefaultClass : PlayerClass
{
    public DefaultClass()
    {
        className = "Default";
        health = new HealthSystem(150);
        speed = 5.0f;
        jumpHeight = 2.0f;
    }

    public override void UseAbility()
    {
        Debug.Log("Playing default class");
    }
}

[eternal needle]

scriptable objects here completely replaces the need for this derived classes

Along with attaching abilities compared to what you're doing of defining it in code as inheritance

[hasty sleet]

I usually imagine "object" as a type that stores data and methods, not a game object that seems distinct from manually-defined objects

It's a bit abstract, I guess

[astral falcon]

As bawsi said, you could just create a scriptableobject that is your "Default" player stats and go from there.

your playerclass could hold a list of abilities that you can assign. Same goes for items, armory or temporary effects. You should write down what type of properties you need on your player that will change through the course of your game

[mild lake]

Again i wanna applogize because i feel like i'm going in circles lol, but how would i code unique functionality for each class that falls outside the definitions of the scriptableobject?

[summer stump]

GameObject is just a class that inherits from UnityEngine.Object

[eternal needle]

everything is an object. It would be the same if you defined it like

new GameObject(Stats, Movement, Ability1...);

thats really all unity is doing anyways.

[mild lake]

Well actually- let me clarify

[hasty sleet]

I meant the instance of a game object rather than the type

[summer stump]

I fail to see the distinction I guess

[mild lake]

Specfically just the ability, because i imagine it would be like "summonbomb.cs" with just a few lines of code, which seems inconvient to me to do for every ability, or anything unique

[eternal needle]

Thats actually desired in most cases

[astral falcon]

Your scriptableobject wuld just be the container for your abilities. you could add abilities from a sharing class for example and tie that into your stats, how they affect them for example

[astral falcon]

you would have an abilitiy class that has abstract methods, and inherit from that to create your custom behaviour which needs to fit the methods defined by your base abilitiy for example.

[hasty sleet]

Instances are not types so they can't be treated the same way as an object in OOP. You can't inherit from an instance

[raw token]

In the traditional sense of an "object" being an instance of a class, a GO in a scene is an instance of the GameObject class

[hasty sleet]

Yeah, that's how I view it

[astral falcon]

why are we mixing up code structure and runtime lifetime here?

[hasty sleet]

I don't know if there was confusion earlier

[edgy needle]

project worked n dis jus appeared idk wth is dis script

[astral falcon]

Your IDE should tell you, what is missing. your ListPool is not present for your code at that line

[summer stump]

There is some misunderstanding of what instance means here
Of course you cannot inherit from instance...

[hasty sleet]

I mentioned that staple OOP features shouldn't be the default approach to solving a problem in Unity, as composition is pretty much the go-to default problem solving approach.

If you approach solving a problem, subclassing should not be the go-to for most problems.

[edgy needle]

i didnt even write it and idk its sytsem script

[hasty sleet]

Then bawsi said game objects in the scene are objects in OOP, then I made the distinction above.

[astral falcon]

oh, its a system one. try to delete the packagecache in library and let it reimport

[summer stump]

Because that is correct. It IS an object in oop.
Yes composition is preferable... but your distinction is not really making sense, it is confusing unrelated issues.
Bawsi supports composition all the time though. No one is going against that

[edgy needle]

where is library folder located

[eternal needle]

This is better, usually abilities would inherit from some methods. You describe it as inconvenient but consider it the other way around, you would have the capability of writing only a few lines of code and an entire new game mechanic.
just to note this would be completely different from scriptable objects. Scriptable objects literally just save you from having to define stuff in code. For example this is my entire scriptable object code for defining the default stats a character can have. https://gdl.space/wujesiqeru.cs And one method is literally just editor utility to auto populate the stats with 0.

[summer stump]

[raw token]

You might also try just restarting your editor, if you haven't. Sometimes that can clear a wonky editor state

[hasty sleet]

I think someone disagreed with my statement about traditional OOP and inheritance being a poor choice and I've been locked in a loop of clarifying my statement

[summer stump]

I think you may have misunderstood what they said

Hey,
Can someone happen to give me a script what changes an animation by clicking on a bottom and this name indicates the animation on the cube?

Or generally help me with the topic?

[astral falcon]

Did you google it? Unity Button, Click, Animation, Clip?

[mild lake]

Would it be wise to overide a abstract function inside my movement script? So lets say i wanted to make a class make a sound when they jump, i could just make a file and then code my unique functionality inside it, hooking into the method i had defined to trigger it, and then possibly refrence that in the scriptable object? I don't know if i'm cooking or this is dumb haha, my brain is turning to mush

[astral falcon]

Maybe take a break?

[mild lake]

Fair

[summer stump]

No, no one will give you a script. If you describe what you tried and what problem you have with it, someone can help

[last orbit]

I'm really bad what Google is going on. But yes I've been trying for 2 days

[eternal needle]

this part is really hard to suggest because movement systems are complex. Thats definitely a possibility but usually you'd want some central way of moving and inheriting just to only add a sound would feel a bit weird.
I would do this the other way, have every character possibly play a noise or animation on jump. If you dont attach a noise or animation, it simply doesnt do that logic

[edgy needle]

yeah, facebook sdk completly fucked up my project by just importing it, i see on forums now its they fault

[eternal needle]

my ability system is by no means perfect (its actually pretty shit) but one thing is i made it really easy to define animations that play. The exact same logic will be applied to sound

An enum which simply says when to play it, when its charging, when the ability is used, when the ability exits. How long it should take etc

[mild lake]

Again, just to get a better idea of what's going on here, could i see the melee script?

No problem whatsoever though if you'd prefer not to

haha, i'm reading the latest hytale blog and they're discussing the exact same thing as we are. very odd coincidence

[astral falcon]

Its not an easy topic, especially about players with abilities like in an rpg or similar. You have to keep track and know, what your code is doing. So its good, you think about it a lot.

[mild lake]

Yeah i wanna start off with something more flexible this time. I all but doomed myself with my last game

[eternal needle]

this logic is actually on my AbilityBase, this is the part for inheritance. the melee script doesnt have any logic related to animations. I dont mind sharing snippets, its really simple. There is one thing i do backwards for simplicity in how the code is written. Basically on charge up, ill try calling the animation code with AnimationTiming.StartChargeUp and check if it matches the one chosen in inspector. If not, return. Same for ability, and exit ability.
https://gdl.space/rukaladexo.cs

[astral falcon]

We all been there, thats how we learn 😄 Also using pen and paper sometimes helps before writing any line of code

[eternal needle]

for the snippet above, I could easily do it like

    void AbilityInternal()
    {
        if(animationTiming == AnimationTiming.Ability)
          HandleAnimation();
        Ability();
    }

i just didnt want to

the script is quite long so i excluded a lot like where i define my fields and the enums but you can definitely figure that part out :p

[mild lake]

Gotcha. Thank you all so much

i'ma isten to twentacle and get some sleep

[blazing ruin]

btw. Do you know when I have 3 levels, but have similar menu, have 'basic' similar elements for each, for instance on the screen. Is not weird create prefab on Level Base object, which contains UI, Coin Manager Selector. You get it? @teal viper

[teal viper]

Sorry, I don't understand what you're trying to say. Can you maybe use a translator?

[blazing ruin]

Well, look at this. I have in Level 1 scene such elements as: pause menu, win menu, lose menu and other elements that will be the same in all scenes (levels). Is this how it should be done, to have a prefab called Level Base with all these objects?

[teal viper]

It's one way of doing it. Another one is putting the shared prefabs, like ui into a DDOL scene.

[feral sapphire]

how can i fix this issue? all i know is that the number is to high.. but i havent found a way yet to solve this issue.

[teal viper]

You can't the number is too big. Unity playerprefs don't support long afaik

[feral sapphire]

hm. is their like no way to convert those numbers into letters tho?

[teal viper]

There is. Into string and back

You'd need to save it as a string though

[feral sapphire]

So i have to put int into string and back?

[teal viper]

Yes. Or use a different serializer

[burnt vapor]

Consider learning about JSON Serialization and how to write JSON to a file, instead of using Shitty PlayerPrefs

Although you can also learn JSON Serialization and use that to write strings to PlayerPrefs

[junior finch]

I have a question, When do you use shaders and when do you use shader graphs. I understand shaders are mainly vertex and fragment. but if i want to make a special effects i use a shader graph. I might also be explaining it wrong

[teal viper]

Shader graph just generates the shader code for you.

You use shader graph, when you don't know how to write shader code and are too lazy to learn. Or for convenience

[junior finch]

hmmm, that explains it

Then i have a question, I want to make bullets that look like lasers. From there I am guessing it is more of a vfx thing than a material

[teal viper]

Depends. There are many ways you can implement it.

The simplest one would probably be a line renderer

[junior finch]

hmm let me look that up real quick

hmm i see

[late yew]

In my current project I want the player to unlock multiple 'charges' of their dash ability, and I have them regenerating in update. with my current function it just permanently sets the timer to max, so it's never counting down, but I can't work out how to fix it. If I use a coroutine will that keep getting reset as well?

if (availableDashes < maxDashCount)
{
    dashCooldownTimer = dashCooldown;
    if (dashCooldownTimer > 0)
    {
        dashCooldownTimer -= Time.deltaTime;
        if (dashCooldownTimer <= 0)
            availableDashes++;
    }
}

[blazing ruin]

Thank you for your answer. It's enough for me that you give me an understanding of what approaches exist. And I can figure them out on my own

[ivory bobcat]

You'd evaluate the available dashes only once (not every frame - maybe when using dash) and reset the timer then. Elsewhere (maybe in Update) would be where you'd count down the timer etc.

hey peeps

so I"m making a card game and I want to queue up all my animations and actions in a way that waits for each to end before starting another one

Thing is, I still want for user interaction to be possible while the animations happen

My friend recommended me to use Coroutines but I also heard of Async

So my question is, which one do I use for the animation in a way that doesn't lock user input until they finish?

[broken cargo]

Both can be used. Unity doesn't really work good with raw async stuff, but you can await a callback from a coroutine. So use whatever is easier for you in this specific case.

[remote osprey]

So coroutines won't take all processing away then?

They still share it with other routines like input detection and the like

Because I saw in a video that the coroutine is run in the mainthread

[broken cargo]

it is, but it doesn't block any other code

[remote osprey]

Ok, thank you!

[broken cargo]

In general pretty much everything in Unity runs in one thread

[remote osprey]

Got it

Thanks for the info!

[burnt vapor]

Async-tasks work the same as Coroutines in Unity, FYI

And with new Unity there are Awaitables which make asynchronous programming even easier

[broken cargo]

Sometimes it can get out of the main thread if you wait for some 3rd party stuff for example

[swift crag]

This sounds like two different questions:

• How do I use the new input system?
• How do I add new features to a movement component?

A dash is a dash; it doesn't matter if it's triggered when Input.GetKeyDown(KeyCode.LeftShift) returns true or when you get a callback from the "Dash" action

it's hard to answer that question because my answer would just be "i learned how to do it" 😉

Try thinking about how you'd implement that movement feature completely on its own

so, not as part of a more a complicated character controller

you could implement a character controller script that does nothing but dash

when you press shift, you look at the current movement input

store that and move in that direction for half a second

[vast sandal]

In addition to what fen said:
Try tinkering with the code.. make the jump higher, try to get the logic thats underlying..

try to code something you've allready seen.. like a jump maybe, without looking too much at the code.. could you get the jump working in a different axis? is that maybe close to a dash?
how could you tweak it to behave like a dash..?

Lots of stuff in the beginning is just "tinkering" and picking stuff up you've seen somewhere.. squash stuff together and see what happens.. just what smaller kids do, they see something, try themselves and see what happens 😄

[timid oriole]

I kinda disagree don't go through the entire thing I think once you learn the basics from it move on

This is complicated enough that I probably wouldn't use either one. Instead I would build my own state machine for this.

They're UnityEvents, so you do something like:

How would you do this?

This seems wayyy too complicated for a State Machine in my very questionable newbie opinion

[pastel sinew]

Thanks Ill look more into UnityEvents then.

[pastel sinew]

What would that subscribe to? What I linked says you can specify specific cameras.

[swift crag]

oh, this is a component

stick it on the object that has your virtual camera and then add listeners as usual

[young smelt]

What does it mean for me too be getting this from play console after I just updated it to mention that I will be using advertizing:

1 Error
Error
Your advertising ID declaration in Play Console says that your app uses advertising ID. A manifest file in one of your active artifacts doesn't include the com.google.android.gms.permission.AD_ID permission.

If you don't include this permission in your manifest file, your advertising identifier will be zeroed out. This may break your advertising and analytics use cases, and cause loss of revenue. Learn more

You can remove these errors by updating your advertising ID declaration

Apps that target Android 13 (API 33) without the AD_ID permission will have their advertising identifier zeroed out. This may impact advertising and analytics use-cases. Learn more

[swift crag]

the message clearly explains how to solve the problem

[young smelt]

And I already added it to my manifest yet it's still saying all that:

</application>

</manifest>

[swift crag]

this is also not a code problem -- it should go in #📱┃mobile , most likely

[young smelt]

But I did what they asked. I set my manifest to custom and edit it to inslude what they asked for

[young smelt]

oh

damn the other places are ghost towns. Ok then

[robust turret]

hello

'''cs
//
public void startGame()
{
startGameScreen.SetActive(false);
GameObject.FindGameObjectWithTag("Player").SetActive(true);
GameObject.FindGameObjectWithTag("Respawn").SetActive(true);
}
'''

how can I reffer to the tagged game objects without setting an object for them?

What's that supposed to mean

[robust turret]

so here is how it is...
Whenever start game button is clicked, I want startGame screen to deactivate, which it does.
Then spawn the player and obstacles tagged as respawn

public playerScript player;

player = GameObject.FindGameObjectWithTag("Player").SetActive(true);

instead of this

is there any way to directly reffer to them?

[astral falcon]

Why dont you want to store your player on Start() for example and then access that in all other methods?

[willow scroll]

Let me rephrase it:

How can I refer to the GameObject with a tag without having to serialize a field for it in the Inspector?

It that right?

[robust turret]

thank you for translation ^^

[willow scroll]

In order to reference an object using their tag, you'll have to use the GameObject.FindGameObjectWithTag method

[young smelt]

store it in a private field after searching for the tag in start

[robust turret]

so field is still needed huh

[willow scroll]

Surely

[astral falcon]

Or let it subscribe itself to your "GameManager"(?) , if it is changing because you are destroying it or whatever

[astral falcon]

You want to force writing unperformant code? 😄

[willow scroll]

private GameObject yourObject;

private void Awake() => yourObject = FindGameObjectWithTag("YourObject");

[robust turret]

okay thanks

[astral falcon]

Also if there is only one player alive anytime, you can just use the singleton logic to access it

[robust turret]

how u write it?

[willow scroll]

What does it mean?

[robust turret]

like a code window

[willow scroll]

// your code goes here

[astral falcon]

You dont need to search for it again, when you assigned player once

` copy paste this three times 😉

[willow scroll]

` <- this symbol should be on the left side of your key 1

ok, so i have this code - https://gdl.space/yayocuhapu.cs
it's from a wall ride youtube video - https://www.youtube.com/watch?v=WfW0k5qENxM&t=1s

and i want to be able to not jump on the same wall twice.
i'm on it for 2 hours already trying many different approaches with no avail.
i know i need to store the wall im riding on as a variable and then compare the next wall im riding on to the last wall but the

(wallLeft || wallRight) 

is messing me up.
can someone think of a way i can do it?

[swift crag]

That evaluates to true if wallLeft or wallRight is true

What is the problem?

[astral falcon]

Your Method WallJump or the input check itself should look for the last wall touched and then skip if its not null for example. set it to null if both walls are null (false)

[swift crag]

ah, you're asking how to add an extra condition to what you already have

yeah, you can save the wall you found in CheckForWall

that'll be in rightWallHit / leftWallHit

You could also just remember if the last wall you were on was a left wall or a right wall

[astral falcon]

As long as you can not turn around on the wall 😉

[timid fulcrum]

i'll try and update

[swift crag]

you might do both!

Although that could make you fall down if you pass from one wall to another

[vagrant ledge]

guys how do I check if an animation is playing in an if statement?

[astral falcon]

using mecanim?

[swift crag]

(that is, the built-in Animator)

[timid fulcrum]

private void CheckForWall()
    {
        wallRight = Physics.Raycast(transform.position, orientation.right, out rightWallHit, wallCheckDistance, whatIsWall);
        wallLeft = Physics.Raycast(transform.position, -orientation.right, out leftWallHit, wallCheckDistance, whatIsWall);
        if (wallRight) currWall = wallRight;
        else currWall = wallLeft;
    }

so like that?

[swift crag]

This would set currWall before you even start a wallrun

so you'd never get to do a wallrun at all

You'd need to set the current wall when you stop a wallrun, I think

[timid fulcrum]

so i can try to add another bool to check if i touched a wall before already and set it to true

once wallride for the first time

private void CheckForWall()
    {
        wallRight = Physics.Raycast(transform.position, orientation.right, out rightWallHit, wallCheckDistance, whatIsWall);
        wallLeft = Physics.Raycast(transform.position, -orientation.right, out leftWallHit, wallCheckDistance, whatIsWall);
        if (touchedAWallAlready)
        {
            if (wallRight) currWall = wallRight;
            else currWall = wallLeft;

        }
    }

// in state machine vvv
if ((wallLeft || wallRight) && verticalInput > 0 && !playerMovement.grounded && !exitingWall)
        {

            if (!playerMovement.wallRunning)
            {

                StartWallRun();
                touchedAWallAlready = true;

            }

[vagrant ledge]

//Drop if equipped, "Q" is pressed and fpsCam is playing the "Idle" animation 
if (equipped && Input.GetKeyDown(KeyCode.Q)) Drop();

how Do I do This ??

I wanna call the drop function if the fpsCam is playing the Idle Animation

[languid spire]

So set a bool when it's playing and unset it when it's not. Then just check the bool

[vagrant ledge]

but that's what i dont know 😅
how do I check if the fpsCam is playing that animation?

[languid spire]

Somewhere in your code you must set it to play

[vagrant ledge]

its set to play in another script

[languid spire]

so ?

scripts can reference eachother or you can pass the bool via a singleton/manager

[gleaming kraken]

is there a better way to do this

im really starting to feel like yandere dev

[languid spire]

Enums and Arrays

[swift crag]

If all you're doing is calling AddListener on each button in your Awake method, you can just hook up the events on the Button components instead.

[gleaming kraken]

this is for keybind rebinding

cant really use an array

[languid spire]

yes you can

[swift crag]

actually, this is the perfect place to do so

[gleaming kraken]

an array is a single value though

[swift crag]

you aren't trying to do specific things with each button

[gleaming kraken]

i should use a dict

[swift crag]

no, you should make a class that holds a button and a text component

[burnt vapor]

This depends entirely on what you are trying to do though

[swift crag]

[System.Serializable]
public class RebindingButton {
  public Button button;
  public TMP_Text text;
}

now you can serialize a List<RebindingButton>

[gleaming kraken]

just a basic keybind rebinding thing

[gleaming kraken]

huh

[swift crag]

Even better, you could really just generate the rebinding interface from a list of input controls

[gleaming kraken]

that might actually be better

[naive pawn]

why not a struct?

[swift crag]

I generate my control lists from my input actions. Each entry is a prefab.

[swift crag]

No reason. A struct would make sense here.

I do often use a struct in this kind of situation

[naive pawn]

so, preference, i suppose?

[burnt vapor]

Yes then probably follow Fen's advice. Maybe you should also apply a special key that is unique to the key (KeyCode could work here) to find it again

[burnt vapor]

I'd argue structs are not suitable to advice to beginners

[naive pawn]

why not?

[swift crag]

it's just not very important here

[vast vessel]

Agent.speaker?.SaySentence("Death");
will this null check work instead of an if statement, if Agent.speaker is a monobehavior?

[swift crag]

No, it would not behave correctly.

?. only cares about genuine null references

[vast vessel]

what can i do instead that is also short

[burnt vapor]

Struct behavior can be very complex and unexplainable for beginners. It also makes negligible difference here when it comes to performance like what structs would have

[swift crag]

When you destroy a unity object, it becomes equal to null, but it's not actually magically turning into a null reference

[naive pawn]

how is it any more complex than a class

[swift crag]

i mean, the main problem is that myStructList[0].foo = 123; doesn't work

other than that it's going to look and feel the same

[burnt vapor]

Rebinding through code will have different behavior

[naive pawn]

if you know classes, you're already 90% the way to a struct

[swift crag]

The struct is not being mutated here.

It's just a bundle of a button and a text component.

[burnt vapor]

Not in this question, but who said that it was purely going to be done through the editor?

[vast vessel]

any other ways of doing a null check on unity objects, that is short, syntax wise?

[naive pawn]

"if you pass a struct around like a class, it's like you're making a new one."

explanation done

[swift crag]

not that I'm aware of, unfortunately

Consider getting rid of the field access entirely

[burnt vapor]

Yes, behavior that the average beginner would not be aware about 😎

[swift crag]

perhaps you should just tell the agent to say something

[vast vessel]

damn

[naive pawn]

yeah, so tell them? it's not more complex than classes, it's just different. it's not unexplainable at all

[swift crag]

the behavior is also irrelevant for a "bag of data" type

[naive pawn]

if your "average beginner" can't adapt to structs, then they barely knew classes to begin with

[burnt vapor]

Why tell them when you can just suggest the familiar class based approach instead? Not to mention this is not the only explanation that would explain structs. It's much more than that

It answers absolutely nothing about the question, so it's pointless

[naive pawn]

familiar class based approach instead
literally the same thing

[swift crag]

I'd just use a class because it doesn't really matter at all here

If you have two options, go with the more familiar one

[burnt vapor]

This is not a channel for code reviews

[naive pawn]

we're discussing beginner-related coding concepts, aren't we

i see no reason to bar beginners from using structs

[burnt vapor]

Does it fall under their question?

[vapid trellis]

Hi

[naive pawn]

no, does it have to?

[naive pawn]

i asked a question too, yknow.

[burnt vapor]

So why bother changing an answer that works fine and point them to use a more complex system? Structs makes no difference here and suggesting it over classes is just going to make it confusing in the future why stuff suddenly doesn't work they expect them to.

[naive pawn]

you answered with something i didn't understand, so im starting a discussion

[timid fulcrum]

@swift crag @astral falcon just updating, i succeed getting what i want using strings -
https://gdl.space/avoqecoxag.cs
if you wanna check it out

[swift crag]

i would replace that with an enum

that way you can't accidentally, say, write "NocurrWall" and have it break

public enum WallState {
  None,
  Left,
  Right
}

This creates a new type -- WallState -- with three values

[naive pawn]

why bother changing an answer
i didn't? im asking my own question
structs make no difference here
which ive gotten an answer on.
point them to use a more complex system
it's not more complex, and i'm not pointing them to it; im asking why you can't point them to it

[swift crag]

WallState.None, WallState.Left, WallState.Right

[timid fulcrum]

@swift crag good idea

[burnt vapor]

Your question was answered a while ago then, so let's stop the conversation 👍

[naive pawn]

but clearly you aren't interested in the discussion further than just pushing your own point, so sure, let's drop it

tf you just said to stop the conversation lmao

what do you want

[burnt vapor]

FYI, to avoid weird behavior you should get your components in Awake, not Start

Awake runs before anything else, and is generally the point where you get your components, unless it's deliberately done

[spare mountain]

what sorts of weird behavior? 👀

[timid fulcrum]

@swift crag actually i dont think i'll use it since it complicates things for me and it works right now. also i am positive i will not set it to "NoCurrWall" by mistake 😄

[burnt vapor]

I guess it's more that when you have scripts communicating with eachother, Awake is the point of Initialization, and Start is where the communication happends. See this flow: https://docs.unity3d.com/Manual/ExecutionOrder.html

[swift crag]

Yes, it's only an issue when multiple components are interacting with each other

[burnt vapor]

So when you do the initialization in Start, there's a chance the component reference remains null

[swift crag]

Suppose you have this setup:

[burnt vapor]

In Unity it's not guaranteed that one script runs before another, so it could randomly break because of it

[swift crag]

A.Start: use GetComponent to get a component

B.Start: tell A to do something that needs the component

If B.Start runs first, you'll get an error

Of course, what you should really do is just assign the references in the inspector ahead of time

setting yourself up in Awake and then interacting with other things in Start is just a useful rule of thumb

[gleaming kraken]

you can set it up on project settings though

[burnt vapor]

Yeaaaaaahhhh... I would not really advice that though

There's also DefaultExecutionOrder attribute

You're right though

[queen adder]

while playing i'm supposed to click on a stone and the rock will be placed in the inventory. but when there are many rocks nearby, when i click on a single one all of them get picked up. Any solutions please?

[slender nymph]

you'd have to show your code. but most likely you just need to rethink how you are going about it.
a raycast to get just the one you are looking at is typically sufficient and you just call a method on only that object to interact with it

[polar acorn]

How are you detecting the click?

[queen adder]

and this is a script attached to every interactble item like the stones

[slender nymph]

yeah so you're just checking for input on every single interactable object and assuming the player is looking at that object while in range. perform the interaction from the component that does the raycast.

[polar acorn]

If you're checking if the ray hits an object, why not just actually call a function on that object instead of just setting a boolean and let every rock try to guess if they're the reason the bool was set?

[queen adder]

Thanks for your help guys i'll look into it and hopefully it works

[late burrow]

ok so i have type1 which holds type2, how i make type2 take values from type1 on new() without referencing type1

since i cant put type2 constructor into type1

[gaunt ice]

you cant assign some value without knowing value
you can pass (reference of) type1 instance to type2 stored in type1 or pass what type2 needs, when constructing type2 outside type1 struct/class constructor

[wintry quarry]

You either pass parameters into the constructor or assign the fields from outside

"type1 holds type2" is really vague and doesn't really explain much BTW

It could mean it's a nested type, or there's a field of that type, or who knows what

But either way, you either pass params or set from outside.

[late burrow]

thought i can mark parent class to always have parent variable accessible

[raw token]

so type2 extends type1?

If so, type2 can access any public or protected members from type1

[polar acorn]

You wanna give that sentence another go with maybe some specific examples because I have no idea what you're asking

[wintry quarry]

Parent class implies an inheritance hierarchy, that's something you didn't mention in your original question

You are being too vague

Like I said "holds type 2" isn't very meaningful or specific

[polar acorn]

It's because they have zero clue what they're doing and are just guessing what words mean

[stuck palm]

how can i delete a script from an object at runtime>

[polar acorn]

Destroy

[stuck palm]

thank you

doesnt that destroy the object too or?

[raw token]

Check the docs:

Removes a GameObject, component or asset.

[rich adder]

it can destroy any Object

unity Object that is

components inherit from Object so those are included

[stuck palm]

i see, thanks

[polar acorn]

If you call it on an object, yes

but if you call it on a component it destroys that component

[polar acorn]

You ever notice how the moment you ask for the tiniest iota of clarification they vanish like a dad going out to buy a pack of cigarettes

[verbal dome]

The "refuses to elaborate further" is real with this one

[swift crag]

fun game: destroy random stuff you found with Resources.FindObjectsOfTypeAll<UnityEngine.Object>()

this eventually causes an editor crash

[lost hamlet]

My friend found something stupid to try a while ago. I haven't tested it but basically patching Time.deltaTime with Harmony to return a random float

What could that exactly break

[swift crag]

everything that is time-dependent

[lost hamlet]

Everything?

[swift crag]

since the amount of time that passe per frame will now be a random quantity

[stuck palm]

whats Harmony

[swift crag]

no, things that are not time dependent (e.g. something that deals damage to you once when you touch it) will behave as usual

[swift crag]

it is a tool for patching a built game (uh oh, community conduct violation!)

it's for C# in general, but it's designed for game modding

[lost hamlet]

You could use it in your own game for some stupid things

[late burrow]

how to do that

[lost hamlet]

I had a use for it a while ago but forgot what

[late burrow]

since when i try create type2 it asks for type1 parameters

[brave compass]

Yeah, I use it for editor scripting sometimes, like to hook into editor GUI that isn't otherwise accessable.

[lost hamlet]

Right that was it

[swift crag]

I've used it before for Rimworld modding. Very nice system.

but anyway, #📖┃code-of-conduct , 😉

[brave compass]

This isn't possible, because Time.deltaTime is an extern property. It has no method body for Harmony to modify.

[summer stump]

#💻┃code-beginner message

[raw token]

It's still not super clear what you're talking about... Maybe you're trying to call the parent class's constructor from the child class? You might be looking for the base keyword?

[summer stump]

Perhaps provide the information that was requested

[stuck palm]

I have this code that adds all the movement vectors of a controllers to influence one marker. Why is it if one controller (red) is moving up and the other (green) is moving down, then the resulting movement is orange?

 void Update()
    {
        Vector2 combinedVector = Vector2.zero;
        foreach (PlayerInputController pic in _controllers)
        {
            combinedVector += pic.markerMove;
        }
        
        combinedVector.Normalize();
        
        _transform.anchoredPosition += combinedVector * (speed * Time.deltaTime);

[polar acorn]

Show some actual code and errors so we know what you're talking about

[late burrow]

first class holding array of second class and second class should have access to first class stuff

[verbal dome]

Have you tried logging combinedVector?
Looks like the up/down direction's aren't exactly up or down, so their sum doesn't add up to zero. Then you normalize it which makes it stretch in whatever direction

[slender nymph]

seems like one or more of those vectors you are combining has a non zero value on that axis

[summer stump]

Please provide what has been asked for multiple times
Yeah, trying to make sense, but too vague

[stuck palm]

i see. how can i avoid this stretching? im trying to make this marker something that users can fight for, but actually using it makes it move in a strange direction as its stretching like you said

[verbal dome]

What final value do you expect when you add up and down together?

Zero?

[stuck palm]

basically, yeah

the vector goes in all directions as its coresspending to the joystick

[summer stump]

This kind of two way referencing is a bit concerning either way. With more details there is certainly a better way

[verbal dome]

Maybe don't normalize but clamp the result instead
Though I'm not sure I quite understand the game mechanic here

[stuck palm]

you know how in smash when you get to map select all players can control a single marker to select something

im trying to make that

clamp makes sense

[chrome tide]

is it a good practice to use Scriptable Object to hold data that needs to be accessible across the game scenes?

[polar acorn]

In general, modifying a scriptable object at runtime is a bad idea, because it behaves differently in the editor as it does in a build, which can make debugging difficult. In the editor, changes to the ScriptableObject at runtime persist forever. It modifies the asset on disk and those changes are permanent. In a build, though, it will only modify the SO for that run of the program. Closing the program and re-opening it will reset the values to what the project was built with

[chrome tide]

ok, thank you

[summer stump]

Gone again

[polar acorn]

👻

[swift crag]

actually, no, just writing to the object doesn't write the change to disk!

unless you manually edit it some more in the inspector, I believe

i tested this a while back because the behavior of scriptable objects was driving me nuts

[swift crag]

(unlike modifying a material...)

[polar acorn]

Really? And you're referencing that specific asset, not one made with CreateInstance?

[swift crag]

Right.

It doesn't get dirtied

[timber tide]

yeah what does it exactly do? Create some temp instance and persists till you restart the editor?

[polar acorn]

then why do the changes persist between sessions 🤔

[swift crag]

because the object doesn't get unloaded

[polar acorn]

do they still persist between sessions?

[timber tide]

I just ran into that issue when I wanted to see if I could save persistent data during playtime to SOs ;p

[swift crag]

If you load a new scene and nothing is still referencing the object, it gets unloaded

[polar acorn]

Ah, okay. So if you close the entire editor without saving, it would go back to what it was

[swift crag]

Right

I store some mutable data in ScriptableObjects. I put them in a dictionary when the game starts and keep them there forever, so they never get unloaded

[swift crag]

I'm not sure why this winds up changing the serialized data, actually

[polar acorn]

Neat! I learned something today 🌈 ⭐

[slow knot]

Soo, hello! I've been making a clicker game in Unity 2D, and not sure how I can make that button teleport inside an object, I've tried to code it, but ended up glitched in different screen sizes.

[rich adder]

show current code you tried

[slow knot]

After it ended up like that I tried to make it like this, it spawns inside "Main Camera" but realized now when screen size changes it again glitches

  te = "Button has decided to MOVE!";
                Vector3 newPosition = new Vector3(Random.Range(0f, Screen.width), Random.Range(0f, Screen.height), 0f);
                Vector3 worldPosition = Camera.main.ScreenToWorldPoint(newPosition);
                Vector3 localPosition = transform.InverseTransformPoint(worldPosition);                Object.transform.localPosition = localPosition;```

[rich adder]

are you using an orthographic camera?

also what do you mean it glitches, can you show what happens?

[slow knot]

Button tries to move outside of the screen, because when screen size changes, main camera and canvas change positions

[slow knot]

Not sure, I don't have my pc with me rn

[swift crag]

The z component of a screen position is how many units the position is away from the camera

This is computing a position that's 0 meters in front of the camera

[naive pawn]

if you could come back later when you have that available that would probably be more productive since it'd let you show us what's going on and test proposed solutions

[slow knot]

Alright

I will try later

heyo guys!! im creating a pacman in unity as my first project. i've created all the pacman logic and created the maze using a tilemap. i was working on the ghosts now and in order to perform my a star algorithm, i need to get the tilemap down into code as my grid. anyone know how i can do that?

[naive pawn]

that's a pretty broad question. the tilemap already holds a grid, what part are you stuck on exactly? referencing the tilemap? accessing the grid?

[whole parcel]

accessing the grid

[willow scroll]

I wouldn't consider it broad.

[naive pawn]

have you checked the docs on Tilemap?

[naive pawn]

maybe not broad in topic, but broad in that it's unclear which part of the process they need help with

[willow scroll]

This answer shows how to access all Tiles from the Tilemap. Does it guide you the right way?

[whole parcel]

oh yes

that helps a lot

tysm everyone!!

[willow scroll]

Not sure in what form you want your grid to me stored. List? Matrix?

matrix would be preferred

bc im doing an a star right

[willow scroll]

Matrix is only usable if you have a specific number of columns

[whole parcel]

hmmm i see

[willow scroll]

This means, you cannot have

0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0 0

Only a rectangle form.

[whole parcel]

yea i dont hv that

it's in a rectangular form

[willow scroll]

Sure, then you can indeed use a matrix

[whole parcel]

this is how it looks

it should be fine right?

[willow scroll]

If you're fine with making specific positions null

Those where there are no tiles

[whole parcel]

yeaaa

[stuck palm]

How can i check time since a scene is loaded? just learnt Time.time is for application.

[whole parcel]

that should be fine

so how do i get matrix?

[rich adder]

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-activeSceneChanged.html
no idea but maybe, and start a timer?

or just keep track where it was in Time.time

[stuck palm]

looks good, thanks

[willow scroll]

You'll need to store the positions of the Tiles this way:

Vector2Int[,] tilePoss;

[naive pawn]

if directly from the Tilemap, Vector2Int is also an option

[willow scroll]

Yeah, exactly

Fixed

[whole parcel]

    public bool[,] GenerateMap()
    {
        bool[,] map = new bool[tilemap.size.x, tilemap.size.y];
        for (int x = 0; x < tilemap.size.x; x++)
        {
            for (int y = 0; y < tilemap.size.y; y++)
            {
                Vector3Int tilePosition = new Vector3Int(x, y, 0);
                TileBase tile = tilemap.GetTile(tilePosition);
                map[x, y] = (tile == walkable_tile);
            }
        }

        return map;
    }

smth like this?

[willow scroll]

Yes, this is great

[whole parcel]

alrightyy tysmm

[willow scroll]

I also tend to do extension methods to not parse VectorInts all the time

public static TileBase GetTile(this Tilemap tilemap, Vector2Int position) =>
    tilemap.GetTile((Vector3Int)position);

[willow scroll]

I'll send this in case you need it on some point

[remote osprey]

Is there a way to separate my class logic from the class, like, for example, creating a custom object that carries the logic when an event happens then attaching this object to a scriptable object (for example, an npc)?

[verbal dome]

You should seriously try googling more
https://docs.unity3d.com/ScriptReference/Time-timeSinceLevelLoad.html

[remote osprey]

Allowing me to have an event logic and scripting separately?

[rich adder]

you could sure, you can even make them separate SOs

[remote osprey]

That's what I'm trying to do!

But i'm very stuck

[rich adder]

in what way?

[remote osprey]

I just don't know how to insert the custom logic in my NPC SO, for example

oh wait, I just had an idea

[stuck palm]

oh thats a lot easier 😅 you are right

[remote osprey]

Maybe I should create a SO inside my NPC folder then write a class that extends my Event SO, then just attach the script to a variable that will hold that class?

maybe that could work

[rich adder]

You can also easily use Abstract classes here and create a different behavior for each and just call it like
"Behavior" then all you do is Execute the behavior

[remote osprey]

Hmm okay, but that would still be all code I guess

which is not bad I guess

[rich adder]

I mean yeah everythin you do is gonna be all code

[summer stump]

Behaviour is code. Not sure what you mean

[rich adder]

how you piece them together is what matters I think.

[remote osprey]

This is what I mean

I guess I can do a script that is gonna be located in the NPC folder

[rich adder]

well yeah its easier to switch out behaviors if lets say its an SO

[remote osprey]

That should keep my architecture organized nicely

[rich adder]

they all have Execute method or somehing common you can call, but they each do something else. You just swap them

[remote osprey]

Okay!

Thanks for the help, friend!

[rich adder]

goodluck 🫡

[remote osprey]

Hey, i just had another question hahaa

What if I need a DrawCard Behaviour but its different for each card, making a different class for each behaviour seems weird

Is there an elegant solution to this?

I guess making a method for each card and putting them on a delegate but that's bloated

[rich adder]

it really depends

certain things I just use an enum tbh it speeds up the process for me

i'm making a game after all not some code masterpiece

as long as it works and it works well, it doesn't matter how you do it tbh

[remote osprey]

I see what you mean

I'm taking my time tho to learn SOLID well since I never did that before during uni

Although in a real project, yeah, just do what's easier/faster

[rich adder]

yes SOLID is good but remember these are general guidelines, they are not meant to be followed to a T always

[verbal dome]

What kind of stuff happens in DrawCard?

[remote osprey]

Depends on the car

[verbal dome]

Like what differences do the cards have for example

[remote osprey]

I'm copying hearthstone so

Every card has a different behaviour

which makes the architecture complex

[rich adder]

working on a card game also myself, i see what you mean

[swift crag]

they have different behaviors, but that doesn't mean that you need one unique blob of code per card

[stuck palm]

how can i create an error code? if something happens in my game that isnt meant to happen?

[swift crag]

write something to the log file i guess

[summer stump]

Debug.LogError?

[swift crag]

i'm not sure how an "error code" would be used

[rich adder]

Debug.LogError

[timber tide]

big red text that plague the user's screen

[verbal dome]

Lebug.DogError

[slender nymph]

you can also just create your own exceptions and throw those

[swift crag]

if ten cards all make you lose the game when you draw them, you have a WhyDidYouPutThisInYourDeckYouIdiot behavior on those cards

[stuck palm]

no i mean like, error code 123 or whatever for if something specifically happens wrong in my game

[timber tide]

You can keep development mode console going and it'll print the errors in a console

[swift crag]

i dunno, make up codes

[rich adder]

ohh for like the user?

[summer stump]

Make a number for those things and when you get an error log that number

[swift crag]

i'd really just show a coherent error message

[rich adder]

make a const of error codes or something then use a dictionary to print out what they mean

[stuck palm]

yeah

[slender nymph]

why do you need an error code when you can just use a proper message? error codes fucking suck because they don't really convey anything useful to the user to know if they fucked up somehow

[swift crag]

they mostly just take you to weird malware distribution sites

[remote osprey]

I want to have a flexible architecture

[swift crag]

or mean nothing

[stuck palm]

idk i just wanted to know if it was possible 😭

[swift crag]

Yes, that's my point

[summer stump]

Of course it is

[swift crag]

You re-use simple behaviors.

[swift crag]

Debug.Log(1)

[summer stump]

is X possible
Yes

[rich adder]

the default of any question is usually . yes

[swift crag]

Can I answer a non-trivial question about a Turing machine in a finite amount of time?

[remote osprey]

so, instead of making a class for each card, make a class for each behaviour instead?

[swift crag]

Correct.

[slender nymph]

sure, but the codes are arbitrary so you just make them up and log/display them just like you would a regular error message. so the proper message is the superior option

[swift crag]

You may still have behaviors that are only used by one card

[remote osprey]

Interesting

[swift crag]

(just like how MTG has rules that are there for a single card)

Now, architecting this isn't trivial

It'd be a useful place for [SerializeReference]

[stuck palm]

i see. I'm going to make a singleton prefab for a UI element that creates toasts for errors/info, which is why i wanted to ask

[swift crag]

I have a bunch of places in my game that need to "score" things (e.g. decide how much an entity wants to pull a lever)

[rich adder]

You probably want the code internally so easy to lookup in a dictionary thats hold the actual meaning of the code maybe ?

[swift crag]

I use [SerializeReference] to store (nested) scoring methods

[summer stump]

If you remember, this is what I had suggested to you a while ago. What, like a couple weeks ago? My sense of time is off during finals, but it was a bit

That is composition

And it be strong

[slender nymph]

just use a proper error message, you'll save yourself a lot of time and headache so you won't have users contacting you like "i got error code XYZ what do i do?" and then you have to go and look up the error code yourself because why would you have them memorized

[verbal dome]

Have you ran into any issues with SerializeReference in unity 2022+?
In 2021 I've had prefabs with SerializeReference and they got corrupted after some refactoring

[remote osprey]

I remember it, Aethenosity, it's just that I'm doing a completely diferent code, before i was using delegates and built-in methods for everything, now I"m trying to make my code more SOLID

So i'm tripping a bit on concepts still

[swift crag]

If you change a type's name or assembly, existing data will break if you don't correctly annotate the class

[summer stump]

Fair

There is a lot to it all

[swift crag]

The MovedFrom attribute lets you tell Unity what a class used to be named, or where it used to be found

I have used this to refactor before

[stuck palm]

true 😆 thanks

[swift crag]

This happens because it's not serializing the GUID of a script asset -- it's just writing down the name of the type

[verbal dome]

Wait I swear I was looking for something like this but didn't find
Like FormerlySerializedAs but for types

[swift crag]

It was very hard to find lol

It's in UnityEngine.Scripting.APIUpdating

[verbal dome]

Undocumented too, ofc

[swift crag]

boing

[verbal dome]

Okay thanks this will be helpful

[swift crag]

the alternative is to just rewrite the YAML lol

[swift crag]

If you do this, you'll need to re-serialize all of the assets before you can safely get rid of the attribute

[verbal dome]

Gotcha

[dusty silo]

The attached image shows the relation ship between the desired angle (x-axis) and the actual resultant angle between the extrude(vector) and extrude(vector, angle) (y-axis). I don't understand why there is such a large difference between the intended result and outputs. There could be something I'm missing with regard to the rotation function, or something else entirely. Any help woul be appreciated, thanks.

[swift crag]

instead of doing the trig yourself, you can just use Quaternion.AngleAxis to create a rotation

that'll make it a bit more concise, at least

see also Vector2.Angle

[dusty silo]

Do you think that will fix it, if so, why?

[swift crag]

No, but I just try to not re-implement what Unity already gives me!

(and there could nominally be an error in your rotation code, but it looks okay)

also, I believe I see the problem

Vertecies[4] is a point at, say, [3,0]

Suppose you extrude by 1 meter to get [4,0]

Then you extrude by 1 meter with a 90 degree rotation to get [3,1] (let's say that's a counter-clockwise rotation)

The angle between [4,0] and [3,1] is not 90 degrees

you wound up with these vectors

The angle between [4,0] - [3,0] and [3,1] - [3,0] is 90 degrees

[dusty silo]

I have also tried adding the direction vector pre rotation to the vertex's position and then rotating about the vertex, but that just makes a cool circle in the middle of the shape

[swift crag]

Your rotation is fine, but your expectations about the resulting angles are wrong

[swift crag]

(er, imagine that went up to [3,1], not [3, 0.5]...)

[dense root]

Without creating another script how do I avoid the game object being overriden by the another door using the same script?

    private void Start()
    {
        // Scene setters
        previousScene = thisScene;
        thisScene = SceneManager.GetActiveScene().name;

        if (thisScene == "KawagishiScene" && hasEntered)
        {
            player.transform.position = doorPos.transform.position + offset;
            Debug.Log("doorPos: " + doorPos);
        }
    }

[rich adder]

what is doorpos

[dense root]

doorPos is the exterior of the door

I manually set the door position with an offset to avoid colliding with the entrance again

[rich adder]

well you should only add the player when its relevant to the situation

eg if player went in that trigger, it stores player as the one whos in the trigger

if it leaves then the reference should be maybe null so u can return early when null.
or make a bool that only goes true when player is near it/intrigger of that door

[swift crag]

I don't understand what the problem is.

[dusty silo]

Okay, thank you

[rich adder]

player position is setting frrom another door

i think

[dense root]

Correct

So the player is exiting from the wrong door

[rich adder]

well they all have player

[swift crag]

but these are two separate doors

i don't get it

if they all have a player reference then they'll all try to set the player's position, I guess

[rich adder]

yup. either kill the reference when not near or make a simple flag for when is in that building

[swift crag]

You need to indicate which door is being exited from

One option would be to give each door an ID, and to have a static field that stores the target door's ID

I remember talking about this with you a few weeks ago

[dense root]

Yeah I just started trying to fix it today, sorry

[astral falcon]

Or let the player decide where to go instead of moving the player from the door script. As you know what door the player entered, you should have a reference to the door already or like a synced door in your next scene preferably

[rich adder]

Is Building not its own class?

would make it so much easier to just store the Building/door it currently "belongs" to

or otherway around, store door /building object in the player

[swift crag]

yes, having the door yank the player over to it sounds very weird

[dense root]

Thanks for the hints, I'll see what I can do

[slender nymph]

fun fact, this was the advice provided to them over a week ago when they were first asking how to do doors and they decided to do something different anyway

oh lol i see you mentioned that nvm then

[mortal obsidian]

Hi, I'm a programmer, not too advanced but neither too bad, kinda in between, im currently pursue a degree in CS. That's my background, now, my question was regarding starting as a unity/unreal engine dev, I would like to start with android games and eventually javascript games(I suppose you'll have to use js for that). So what books/sources do you recommend? I still don't know C++ nor C# yet, but I usually learn fast and kinda know C, and do know java. So, any recommendations for learning C++/C# fast for game development is welcome as well.

[rich adder]

y javascript game ?
