[drowsy sigil]

How do I ignore specific LayerMasks when Raycasting.

[ivory bobcat]

It would have something to do with that parameter

[drowsy sigil]

huh? Sorry, I'm not understanding what you mean by that

[ivory bobcat]

You'd best elaborate on your specific issue else https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Physics.Raycast.html

[drowsy sigil]

Yea but im very confused on how it works and I don't understanding a single word that the Unity is saying. My english isn't the best

[ivory bobcat]

Show what you've tried

[frail hawk]

do you want rc only detect colliders on a specific layer?

because i am assuming you phrased you question not correctly

[vast matrix]

I am trying to make a bird like enemy that swoops down onto the player and damages them if they're too high. I have all the checks done (damage and checking if the player is too high) but how would I get the enemy to swoop down onto the player?

[frail hawk]

if i understood correctly you want this https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Vector2.MoveTowards.html

but you´d also want to go back to the initial position, so you need to save that position before the movetowards

[ivory bobcat]

We're not certain without knowing more about what they're doing (physics base, animation etc)

[vast matrix]

Oh thank you that's what I needed

[sage mirage]

Hey, guys! I want to attach my prefab on the field in the inspector. How I am supposed to do it through code, because GameObject.Find() works only for objects active in the hierarhcy.

If I want to attach my prefab for example?

I have tried

enemyPrefab = Resources.Load<GameObject>("Enemy");

But this doesn't work

[frail hawk]

you need to instantiate it first

[sage mirage]

so after the instantiation I can do GameObject.Find()

yes but what if I want to attach it earlier

I mean with drag and drop it works

from the prefabs folder

[frail hawk]

then you can do some kind of injection and let the object that instantiats your prefab, assign your prefab to the field

[sage mirage]

I mean

I don't know how to get access to my project assets

there is the Resources Class

but I am not sure how to do it

[frail hawk]

why do you need to do that before, any reason?

[woven thistle]

Could anyone help answer a few questions I have about a 2d game I am trying to start creating?

[frail hawk]

we dont know if we can answer them but we will try

[woven thistle]

I am just trying to start off with a basic character who can move up down left and right, and "You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings" keeps coming up

[frail hawk]

show your code , it seems like you are using the old Input class

[muted sand]

sorry had to go, here it is

[slender nymph]

!input 👇

[radiant void]

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

[woven thistle]

using UnityEngine;

public class CMScript : MonoBehaviour
{
public Rigidbody2D myRigidbody;
public float moveAmount = 10;
// Start is called once before the first execution of Update after the MonoBehaviour is created
void Start()
{
myRigidbody = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update()
{
    if (Keyboard.current.rightArrowKey.wasPressedThisFrame)
    {
        myRigidbody.MovePosition(myRigidbody.position + Vector2.right * moveAmount);
    }
}

}

[slender nymph]

you should consider looking at the stack trace for the error so you can see where it actually originates from

[muted sand]

already tried this

[slender nymph]

screenshot your entire visual studio window with the solution explorer visible

[slender nymph]

click the error error in the console to see the entire message, including the following lines

[slender nymph]

with the solution explorer visible

[muted sand]

i dont use vs that much how do you do that?

[slender nymph]

"vs solution explorer"
View > Solution Explorer

[frail hawk]

the error you posted is actually the opposite of what you posted. it says you are using the old input system. are you sure it is this script that gives this error

[muted sand]

okok

[slender nymph]

so you didn't follow the instructions in the link i sent

[muted sand]

i just did it again now

nothing

[slender nymph]

did what specifically? there are several different steps

[muted sand]

If an assembly in the Solution Explorer is marked as (unloaded), right-click it and select reload project.

Restart your computer.

[slender nymph]

then you've missed something else in the steps. or you lied 🤷‍♂️

[muted sand]

nope

opopup

[woven thistle]

On unity when i tried running the game it said that was the error. When i checked I was on the new input system. is the problem something else?

[slender nymph]

did you look at the stack trace yet

[muted sand]

idk what that is

[slender nymph]

not you

[muted sand]

okay

[frail hawk]

yes the error is coming from another script. not the one you posted

double click on the message

[muted sand]

oh okay i fixed it

for whatever reason .net wasnt installed apparently

[frail hawk]

or we can make it easier, change the input system to both for now #💻┃code-beginner message

[woven thistle]

Are you responding to me when you said change it to both

[frail hawk]

yep

[woven thistle]

This project uses Input Manager, which is marked for deprecation. To manage input in your project, use the <a href="https://docs.unity3d.com/Packages/com.unity.inputsystem@latest">Input System package</a> instead.

This came up when I changed it to both. What do I do?

[slender nymph]

just look at the fucking stack trace so we can actually find out where this error is coming from

[woven thistle]

who are you talking to

[slender nymph]

you. the person i have told to look at the stack trace several times now.

[woven thistle]

I thouoght you were talking to vincordian. What is the stack trace?

[slender nymph]

i already answered that the first time you asked before you deleted that message

[woven thistle]

Im still not sure what the stack trace is.

[woven thistle]

the error is in if (Keyboard.current.rightArrowKey.wasPressedThisFrame)

[slender nymph]

prove it. show the stack trace

[woven thistle]

does this help

[slender nymph]

holy shit dude, that's an entirely different error

[west quail]

i just switched the il2cpp backend but for some reasons i cant add the "using" statements for il2cpp things

i wanna use il2cppreferencearray but cant do it without em

[slender nymph]

isn't that something in the native code, not c#? or is this using a modding library? if the latter then ask for help in that modding community's help channels

[west quail]

tbf i have no clue. i learned unity coding from modding so that might be something to look into

[slender nymph]

okay then what specifically are you trying to do with "il2cpp things"

[grand snow]

Thats because you had to work with processed c# IL in cpp. None of that is relevant to using unity normally

[west quail]

alright so what would an Il2cppReferenceArray be in normal unity?

[grand snow]

Yes we do not ever have to think about mono or il2cpp

c# is used as normal

[west quail]

gotcha

[jovial heron]

i'm creating an enemy base of which other enemies extend there are 3 states every enemy must have Idle Follow and Recover .I wanna make it so that these are the defaults and the specfic enemy can add his own states later but i couldn't find a way to add states to an enum . How should i approach this

[grand snow]

If you mean you want new enum values to exist that cant be done without modifying its definition

What is a "state" in this case?

[jovial heron]

like if enum enemyState has 3 values idle follow and recover those would be 3 states

[grand snow]

Okay so as I said, the enum def would need to be updated to support new values

a switch statement for states that has a default: case could throw and report missing "state implementations" if new ones are added later

[jovial heron]

ok so how should i approach this if i want default enemy states

[grand snow]

abstract functions in the base type

as abstract properties/functions must be implemented

this however requires the class to also be abstract (e.g. EnemyBase is abstract, CoolEnemy : EnemyBase)

[jovial heron]

my base is abstract

what should i more specifically to make default enemy states

[grand snow]

I guess have the function be virtual so overriding it is optional

We are limited with what we can enforce at compile time, we dont have static assert 🙁

[jovial heron]

my problem is quite general i suppose so if you have ever made a game with a base for enemies how did you handle default states?

[grand snow]

If a state is implemented as a function then make it virtual
If a state is a whole object then perhaps they can be optionally provided in the constructor via an override

(This means you can either provide your own or not)

[jovial heron]

a state is a function ig i can make it virtual

i can't really see well how this will go since this is my first enemy base

but i'll try

[mental escarp]

could i get some help with checking if my agent has reached its destination and set the ismoving bool to false? i dont really know how to code at all im just following tutorials right now 😅

basically i want the walk animation to change back to idle when the destination is reached, i tried setting movement parameters and things like that but had no luck, any help would be greatly appreciated (ignore that im using bandicam please and thank you :) )

[rich adder]

well start with the moving bool

also you should def be configuring your code editor properly

[mental escarp]

unfortunaltey i dont know how to do either of those things 😅

[rich adder]

well the bool is simple you try to associate it to something, instead of hitting it with true everyframe. it should only be isMoving = true when the agent speed is above a certain threshold number

the editor . follow these instructions 👇

[sour fulcrum]

#1390346878394040320

[rich adder]

not easy thing to find a specific guide on..

you'd have to already be very familiar with all the nodes involved to make something like that

[muted sand]

what should i do for cameras movement?
should i move the parent of the camera so that it'd move any accessories the player has also?
i don't know any other way to do it, as multiplayer games would need this visualization
thanks in advance

[eager spindle]

Yes, you can move the camera's parent with the player

In a multiplayer game, have the camera as a child of a gameobject. Make a script for the gameobject to follow the player.

[muted sand]

yeah that was what i assumed what i would do, thanks

[wintry quarry]

I recommend using Cinemachine for all Unity games.

[visual junco]

Ton of people talk about developing small games for your first Unity projects
That's fine, but it shouldn't stop you from wanting to develop something bigger

Why not plan a decent size game, and treat each mechanic as a whole project so you technically are making small projects, but it's slowly forming a game you want

just my opinion on a common saying for beginners

[sour fulcrum]

People just don’t do great with that approach

A working game and additions to said game are very valuable, rewarding dopamine treats to consume while learning independently

Working on chunks of a bigger game just leaves you with a heart and a kidney on the pavement, comparatively

Obviously everyone is different tho

[visual junco]

Yeah I guess everyone is different

to me it's been very very rewarding and seeing each mechanic work feels like a huge reward
Like when I got an AI system for police officer working, or the player's movement & camera control

I just envision everything coming together

[sour fulcrum]

Very popular explanation on mvps

[visual junco]

Yeah makes sense

Where would I start if I want to take this approach

The noise won't change from idle to walk/run (it's stuck at Idle, because i put the noise to be at idle at the start) , can someone tell me why it isn't working? all variables are changing fine, and i also put this code in FixedUpdate

[frail hawk]

and you dont have any errors? because it has to be && instead &

[drowsy sigil]

if I want to rotate my player smoothly toward a target, should I be using Quaternion.Slerp or Quaternion.RotateTowards? And is there any reason to ever touch transform.eulerAngles? Im really confused on what to choose

[frail hawk]

there is also Quaternion.Lerp

the difference between Lerp and RotateTowards is that you have an ease while with the other you dont

[drowsy sigil]

ok

[naive pawn]

you're thinking of smoothdamp

[frail hawk]

and transform.euleranlges is just the rotation itself

[naive pawn]

oh you're talking about wronglerp?

[naive pawn]

should I be using Quaternion.Slerp or Quaternion.RotateTowards
depends on what behavior you want and what the inputs are - there's also 2 ways to use lerp, the correct way of actually interpolating, or wrong-lerp, which gets inconsistent smoothing
And is there any reason to ever touch transform.eulerAngles
not to read them, no

[drowsy sigil]

okay, thanks

[night raptor]

Since you can do transform.rotation = Quaternion.Euler(...), there's no need to set .eulerAngles either (those would be equal), but setting them is totally fine too. Just getting eulerAngles often causes more harm than good

This is literally what transform.eulerAngles does btw:

{
    get { return rotation.eulerAngles; }
    set { rotation = Quaternion.Euler(value); }
}```

[sour fulcrum]

Lowkey had no clue about that setter

That’s convenient tech

[night raptor]

I often feel like eulerAngles are bit of sketch and set rotations with Quaternion.Euler only to remind myself that they are equal

Of course for a lot of rotation stuff quaternions are superior

[jovial heron]

i have this enemybase code that has a default enum states(the states that every enemy will have) but when i go to the specefic enemy code i realized that adding new states is impossible since that would require modifying the enum's value , and the enemybase must have enum with default values otherwise i would have to program them one by one for every enemy. how do I handle this ? i don't mind changing the way this whole thing works but i want smth fairly easy to understand for a beginner and efficient if you would suggest to implement big changes

[grand snow]

Perhaps using int as the key and elsewhere the enum can be casted to int or constants can be used

Or you use generics to let you change the key type

[jovial heron]

that would work be it would be less readable i want smth clean and commonly used for enemy bases

[grand snow]

But the current design is flawed if it only uses 1 enum type and you have realised this

Generics would be best to allow any super class to use its own enum but that may introduce new issues.
Perhaps you need a special key type so you can have inbuilt states and custom states?

[jovial heron]

yeah exactly i want to drop enums from base

for smth maybe more flexible and commonly used for enemy bases

[grand snow]

public enum StateType { Default, Custom }

public struct StateKey
{
  public StateType stateType;
  public int stateId;
}

Can be used with a Dictionary for example

[jovial heron]

ok that would work

like a dictionary for the specific enemy?

wouldn't a map be better?

[grand snow]

A dictionary is a "map"

A type that efficiently maps a key to a value

[jovial heron]

oh ok

thx for help

[random badger]

Anyone know how to walking animation in unity?

Is there any script I need to write?

[queen rune]

how do i start learning c#?

[naive pawn]

this is quite a vague question
you need to get quite a bit more specific than that

eg, 2d or 3d? frames or tweening? what perspective? etc

[queen rune]

there's a crap ton of resources and i'm a bit overwhelmed

[naive pawn]

there are resources pinned in this channel

[naive pawn]

most of the resources are alternatives, not steps
choose one and go with it, if it isn't working out, try a different one

[queen rune]

how'd you learn

[random badger]

2D like frame

[naive pawn]

i read the resources

[queen rune]

ah

reading isn't my learning style

i'll probaby try something on youtube

[sour fulcrum]

to be completely honest with you at some point reading is just neccasary for learning a language

especially programming

[naive pawn]

i'd really recommend article resources, much easier to skim or search through

[queen rune]

reading i understand will be nesesecary at SOME point but for now while i'm getting started i'd prefer a video series

[sour fulcrum]

sure but like

keep in mind a majority of the learning process will be reading

[queen rune]

i'm not saying i can't read

i'm saying when i'm learning something i've got no knowledge of i'd prefer visual learning, when i get a feel for the language i'll peek at the docs

[naive pawn]

reading is visual learning though?

[queen rune]

maybe i worded that wrong idk

whats the word

[naive pawn]

you still have to read the code someone else writes in a video lol

[queen rune]

well yeah a programming language is written

[naive pawn]

there's a certain format of how guides/docs are laid out, if you learn that now you can save learning it when you're dealing with more complex topics

it's not a requirement to only use text resources of course, but yeah i'd recommend at the very least familiarizing yourself with them

[random badger]

I try to make sense of it

[unreal quartz]

Good evening

[visual junco]

Video resources are great

make sure you understand what you're coding instead of just mindlessly typing stuff you don't

understanding the content makes it way easier

I'd recommend the youtuber BroCode

[fickle rose]

so uhhhh for some reason my canvas wont listen to any type of input whatsoever. When I hover over a UI button, nothing happens, let alone clicking it. It's SUPPOSED to change scenes, but for some it doesnt do anything. Any ideas?

I have added the command its supposed to run, and it used to work but i come back and it doesnt anymore

do you have an event system in the scene?

Guys im making a prototype, should I make a script for each mechanic or can I group them in a big script?What is your opinion on this?

[rich adder]

[slender nymph]

typically one big script for everything is a bad idea though

[rich adder]

I think someone asked something similar a a bit ago #💻┃code-beginner message

its just for the prototype but I get your point of view

How do I make hitboxes for combat?

Most tutorials last 30 minutes

Using colliders?

[slender nymph]

if learning for 30 minutes is too much for you, then you should consider something besides game dev as a hobby/career path

[stark helm]

You aint here just to judge people

This is a help channel

[slender nymph]

yeah, this is a help channel not a spoon feeding channel

[stark helm]

Some people learn differently

I just want to know the most used method

then I learn myself

I wont spend 30 minutes on tutorials before knowing what to use

[slender nymph]

here's a hint: tutorials typically tell you what to use

[stark helm]

They do that bruh

But 30 minutes is too long

For just some words

[slender nymph]

then game dev isn't for you. 30 minutes of learning is nothing

[stark helm]

Just tell me what yall use for combat

[stark helm]

15 learning, 15 watching a guy talk

[slender nymph]

nah, i am just gonna block you instead. i won't help people who don't want to put in any actual effort

[stark helm]

Yet I can talk on this channel

Bruh, tutorials scrolling aint helping me

How do I instantiate a hitbox and if it hits something getting the hit object back to the script that creates it?

[frosty hound]

You usually don't instantiate hit boxes, Unity has overlap box that can give you a list of collisions
https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Physics.OverlapBox.html

[stark helm]

I found it out

Thanks guys

Guys, how do I pause the game session

I mean I pressed to test my game as usual, but something is wrong

And I cant use my mouse

its locked

I didnt save the file yet

so i cant alt F4

[grand snow]

esc will always unlock and show the mouse cursor inside the editor

If its a build then its up to you to add this functionality

[stark helm]

Its not a build, Unity is about to crash

I cant unlock it

[grand snow]

If esc does nothing then the editor may not be responding. then you are probably screwed unless it works again

[stark helm]

I forgot to put one line

[grand snow]

poor logic such as infinite loops will cause such issues

[stark helm]

Ima alt F4

Guys if Alt F4 doesnt work

then what is the next step

[grand snow]

task manager (to kill the process)

google can help you there

[stark helm]

It worked thanks

[stark helm]

A backup thing appeared on unity

[grand snow]

cool i dont need a running commentary anymore thanks

Don't read input in FixedUpdate

[naive pawn]

is isJumping set in the inspector? (it shouldnt be serialized to begin with, really, same for isGrounded)

[mellow lance]

I'm still new to Unity but Is this how a lot of games are designed or is my information incorrect/lacking?

1. A "game manager" singleton is created in the main menu on an empty object (or a "bootstrap" scene before it) which holds and saves player data (progress/inventory/lv/exp/etc) regardless of the current scene.
2. Other singletons are also created with it for core systems (like audio and stuff).
3. An Event Handler class sits in your scripts folder that pretty much only holds action properties that transfer a value (example: player received damage equal to int value, or enemy id and damage in a tuple or class) accessed by all currently active scripts to make changes anywhere you need (like that game manager in #1)
4. Game menu, garage/shop/etc, and each individual level each exist in its own scene.

[naive pawn]

that seems quite specific

that's one way, sure. it's definitely not the majority way - there's far too many ways to design the systems to say there's a main way

[mellow lance]

what are the majority/common ways to handle player data and actions and core systems?

[naive pawn]

you're basically asking "what's the main way to make a game"

there's not going to be a singular answer for that

[modern lodge]

^^ depends on your games needs

[mellow lance]

still trying to figure out the norms 😛
(barely even know how to move a character yet, but trying to learn this stuff first as a foundation)

[naive pawn]

yeah no this is not really a proper foundation lol

[wind pier]

In the inspector, there are boxes that are checked or unchecked for isJumping and isGrounded.

[naive pawn]

it's like you're trying to learn every tiny rule of world league football before you figure out how to kick the ball

figure out the small stuff first

none of the big stuff will make sense unless you understand the small stuff

[naive pawn]

and are they checked or unchecked

[wind pier]

isGrounded is checked by default and is Jumping is not checked

[naive pawn]

that part shouldn't be an issue then. might just be the input reading in fixed update 🤷

[hazy portal]

How does one learn about new tools that could make code more efficient? Its my third day using Unity and I made flappy bird and pong but after I went through my code I saw how messy it was but I have no clue how I'd go about making things more efficient since im learning through the documentation

[wind pier]

Maybe, because the game I'm playing comes from a tutorial that's 6 years old.

but not because

[naive pawn]

that stuff typically comes with experience, identifying stuff that's perhaps not as good as it could be and finding ways to improve.
if you have specific instances of code you want to ask about, feel free to (perhaps start a thread in #1390346827005431951)

[hazy portal]

Does this also apply to learning about game structure?

[naive pawn]

yeah

[hazy portal]

or are there any resources

oh I see thank you!

[naive pawn]

there probably are some

but it's not going to replace actual learned experience

skill comes from both knowledge and experience

sometimes a lot of knowledge can substitute for a little lack of experience, or a lot of experience can substitute for a little bit of missing knowledge

but it's much more beneficial to just get both

[hazy portal]

But I feel like getting the knowledge in the way that I'm learning is difficult. I know from experience with another game engine that you could make two scripts communicate but I never would've found this out if I didn't watch an old youtube video a long time ago. Things like that are gamechanging but I have no sense of how many more valuable tools there are similar to that and what they are

[feral hawk]

Yo can someone tell me how to make a multiplayer main menu screen

kinda like 1996 main menu doom feel

[slender nymph]

why does the main menu need to be multiplayer

[feral hawk]

1. servers 2. create server

[slender nymph]

that's just UI, that's not it being multiplayer. do you not know how to make UI?

[feral hawk]

oh thats what i meant

[slender nymph]

check the docs pinned in #📲┃ui-ux to learn how to use unity's UI system

[naive pawn]

ive found out about quite a bit of stuff just hanging out here tbh. also checking out more advanced/system tutorials and such, sometimes they include patterns or stuff that can act as a starting point for further reading.

i've also found that experience in other languages/ecosystems can expose you to many more patterns or designs, which, while maybe not directly applicable, can still be adapted or trigger further reading

there's also that one website for game design patterns or something along those lines

https://gameprogrammingpatterns.com/contents.html this thing

[hazy portal]

Theres a website for that??

ah

[naive pawn]

it's not all applicable, i think it's targetted for c++ or something, but it does give a lot of keywords and ideas to research further

[hazy portal]

Thank you thats gonna be a big help

[naive pawn]

note that adjacent fields can also help, like math (especially vector math) and physics (especially kinematics)

[distant escarp]

would this code accurately give me the normal of the player's position on a wave (please imagine that the SampleWaterHeight function gives the height of the water for the coordinates given)

` public Vector3 SampleWaterNormal(Vector3 worldPosition)
{
Vector2 xz = new Vector2(worldPosition.x, worldPosition.z);

    float waterLeft = SampleWaterHeight(xz + Vector2.left);
    float waterRight = SampleWaterHeight(xz + Vector2.right);
    float waterForward = SampleWaterHeight(xz + Vector2.up);
    float waterBack = SampleWaterHeight(xz + Vector2.down);
    
    Vector3 normal = Vector3.Cross(
        (waterLeft - waterRight)*Vector3.left,
        (waterBack - waterForward)*Vector3.back
    ).normalized;

    return normal;
}`

[swift crag]

That is an approximation of the normal vector, yes.

although it may be inverted

although, hm, i'm not so sure on second thought

The goal here is to find two tangent vectors on the surface of the water

Crossing those will give you the surface normal

You're not calculating that; you're creating a left-vector and a back-vector whose lengths depend on how quickly the water's height is changing

But that doesn't give you two vectors that are tangential to the water's surface!

this will always give you a down-vector, yeah

it's pretty much just Vector3.Cross(Vector3.left, Vector3.back)

You want to do something more like this

Vector2 waterCoord = new Vector2(worldPosition.x, worldPosition.z);

Vector3 centerPos = worldPosition;
Vector3 leftPos = worldPosition + Vector3.left;
Vector3 backPos = worldPosition + Vector3.back;

centerPos.y = SampleWaterHeight(waterCoord);
leftPos.y = SampleWaterHeight(waterCoord + Vector2.left);
backPos.y = SampleWaterHeight(waterCoord + Vector2.down);

This gives you three points that are on the surface of the water. Therefore, you can do this:

Vector3 tangent = leftPos - centerPos;
Vector3 bitangent = backPos - centerPos;
Vector3 normal = Vector3.Cross(tangent, bitangent).normalized;

I'd just make the Y component of normal positive at the end

Hey, I'm looking for some advice on how to handle something that I think is super simple, but my intended approach might be far more expensive than it needs to be.

I'm making a 2D arcade platformer (single screen levels). The ground tiles may have grass on them, which is a separate game object rather than a tile, as it needs to be able to interact with actors in the game in a variety of ways.

When a player/enemy walks through some tall grass, I want it to animate (rustling). What can I do besides using OnTriggerStay2D, check the hitCollider to see if it has a MovementController (custom raycast movement), check that the velocity is over some threshold, then play the rustle animation (if it isn't already playing).

[rich adder]

if its working fine what makes you say its expensive

[willow hill]

I haven't actually made it yet-- just thinking about it while I make the grass assets.

I've read that it's not wise to use GetComponent in Update/FixedUpdate/OnTriggerStay, due to it being relatively slow. In fact, I've alleviated performance issues in previous projects by removing/reworking instances where I had that kind of thing happening. But, in those cases, there were a lot more objects, so it might not be comparable.

[rich adder]

yeah you wouldn't want to do that every frame but why do you need to ?
you only need to grab it once then cache it

does the grass need to detect only player to do that?
if yes you can also just do this player side and on the grass you just have a script that controls animation itself but you detect grass from 1 player script

[willow hill]

It would be for players (game will be one or two player co-op), enemies, and possibly other objects that I haven't thought of yet.

[rich adder]

either options work , do whatever is easier for you to keep track

[rustic moat]

To answer your question, the more "clean" way would be to make a shader for the grass and have it use a gradient noise with the player position but that is probably way overkill for your project.

But absolutely you can just have a on trigger stay that checks if the object has tag "player" or "rustlesGrass" or something and then sets the bool for the animation. That will probably work perfectly for your project

[grand snow]

Just profile in the future to check if this causes performance issues

[willow hill]

I've actually never messed around with shaders. My graphics are made with clay sculptures, so in this case, I've got "chunky" grass, so I'm not sure if that would fit with what you're describing.

I guess doing a tag check before GetComponent is probably more efficient, eh?

[willow hill]

I don't typically fuss over performance because my projects are small, but this has been an issue in the past, so I'm trying to get ahead of it, if I can.

[rustic moat]

Definitely better than get component

[grand snow]

it is more advanced as the shader needs to be able to dynamically react/deform based on some world position

[willow hill]

Once I've confirmed the tag, I'll still need GetComponent to check their velocity.

[grand snow]

But the prior technique of just using 2d physics should be fine if you restrict how many can happen at once in a frame

[grand snow]

use TryGetComponent instead and ditch tags

[rustic moat]

I believe on trigger stay has a collider sent which you can just do collider.attachedrigidbody no?

So then collider.attachedrigidbody.linearvelocity? Idk I haven't used 2D in a while but that's a thing in 3d for sure.

[willow hill]

I'm using a custom movement controller that uses raycast for collision detection instead of rigidbodies.

[rustic moat]

I see.

Then yeah you probably just gotta do a get component and then you can cache those results in a list of player components or something so you don't have to do get component every time.

[rich adder]

just make it easier on yourself let the player pass its movespeed to the movable grass.
Make a component on grass that only receives a float

and unles you have Events for each movement, you would use Update anyway

[grand snow]

Perhaps an interface hmm? 🤔

[rustic moat]

I was just about to suggest an interface. Interfaces my beloved

[willow hill]

So the grass would have the interface? And players/enemies/etc would pass their movement controllers to be cached and queried (for velocity)?

[rich adder]

up to you how you want to approach it, I would not pass them the whole controller just the speed from their movement

does grass needs to be really caring about where the speed comes from player ? enemy ? animal ?

[willow hill]

My thinking was that passing the whole controller would allow me to check the velocity each frame instead of just the velocity of the entity when it entered the grass. It might help to know that the ground blocks are 2x1, so the grass is also wide.

[willow hill]

No, not at all. Anything that has a MovementController will probably be suitable to rustle the grass.

[rich adder]

one thing you mentioned you may have 2 players. Which one should grass 'follow' ?

[willow hill]

I'm picturing a very simple animation of the grass wiggling back and forth, so it shouldn't matter which direction the player/actor is moving.

[rich adder]

just saying if one player is in there then stops moving, then another player enters it should then track both or

[willow hill]

Oh, I see. It would be both (any) object that moves while touching the grass.

[rich adder]

yeah so that comes into your design , it would be easier to just to have a component on player that rustles it ?

so the grass doesnt have to track the velocity , it just needs to know something moved it

[willow hill]

Maybe, but then that component would have to constantly check for overlapping grass.

Maybe that's a better way, though.

[rich adder]

only Enter/Exit

but even an physics overlap in update would be cheap anyway cause ur doing it from 1 player or two not every grass checking everyframe

[willow hill]

That's true. I think I'll try something like that.

Thanks for the input, everyone.

[vast matrix]

I am trying to make a bird-like enemy that swoops down on the player and attacks them. I am currently using Vector3.MoveTowards to move the enemy to the player but the problem is that the enemy moves in a straight line to the player and not in an archlike way. How would I get the enemy to move in an archlike way?

[rich adder]

some type of bezier curve?

or some type of sine

you could also do it a hacky way of still using moveTowards on the main object then have a child object that use Animator/Animations to do different patters of your choosing

[vast matrix]

Oh yeah I can just put multiple points along the route and animate in a sort of way that looks like its curving

*If you have an action asset assigned as project-wide, the actions it contains are enabled by default and ready to use.

For actions defined elsewhere, such as in an action asset not assigned as project-wide, or defined your own code, they begin in a disabled state, and you must enable them before they will respond to input.*
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.19/manual/Actions.html

Does this mean that my actions (that are not project-wide) will not be enabled and will be disabled and I will have to enable them automatically?
And how do I know which is the default action map?

*I'm using Invoke Unity Events behavior for Player Input component for my player.

There seems to be a discrepancy between the actual value of my list and the value shown in the inspector. How do I fix this?

void ReadSaveFile()
{
    string readSaveData = File.ReadAllText(saveDirectory);
    currentSave = JsonUtility.FromJson<SaveFile>(readSaveData);

    Debug.Log(currentSave.levels.Count);
    Debug.Log("Data loaded");
}

    ...
    Debug.Log(currentSave.levels.Count);
    foreach (LevelSaveDictionaryEntry entry in currentSave.levels)
    {
        levelSaveDataDictionary[entry.key] = entry.value;
    }
}

private void Update()
{
    Debug.Log(string.Format("currently {0} entries in current save file", currentSave.levels.Count));
}```

The console correctly logs the number of levels as 13:

but the inspector displays it as 0

[sour fulcrum]

gotta show where your field is defined too

[undone wave]

public SaveFile currentSave;

public Dictionary<LevelIndex, LevelSaveData> levelSaveDataDictionary { get; private set; } = new();

private void Awake()
{
    saveDirectory = Path.Combine(Application.persistentDataPath, saveFileName);
    if(File.Exists(saveDirectory))
    {
        ReadSaveFile();
    }
    else
    {
        WriteSaveFile(defaultSave);
        ReadSaveFile();
    }

    Debug.Log(currentSave.levels.Count);
    foreach (LevelSaveDictionaryEntry entry in currentSave.levels)
    {
        levelSaveDataDictionary[entry.key] = entry.value;
    }
    WriteSaveFile(currentSave);
}

void WriteSaveFile(SaveFile saveFile)
{
    string writeSaveData = JsonUtility.ToJson(defaultSave);
    File.WriteAllText(saveDirectory, writeSaveData);
    if (saveFile.Equals(defaultSave)) Debug.Log("Data saved with default data");
    else Debug.Log("Data saved");
}

void ReadSaveFile()
{
    string readSaveData = File.ReadAllText(saveDirectory);
    currentSave = JsonUtility.FromJson<SaveFile>(readSaveData);
    Debug.Log(JsonUtility.FromJson<SaveFile>(readSaveData).levels.Count);
    Debug.Log(currentSave.levels.Count);
    Debug.Log("Data loaded");
}

(all of this is contained as top-level in the MonoBehaviour class)

[wintry quarry]

I'm not seeing "Data loaded" in your logs at all

[undone wave]

Just ran WriteSaveFile(currentSave), and the json file also seems to have been saved using the correct data, it's just the inspector field that is errorneous

[wintry quarry]

It's not clear what logs we're actually looking at here

or what data you're saving

[undone wave]

here's a better snapshot of the console (without the Update loop)

[wintry quarry]

what are these "13" logs?

Show us the SaveFile code

[undone wave]

i'm pretty sure the first two 13's correspond to the Debug.Logs before "Data loaded"

[wintry quarry]

label your logs better so you don't have to guess

Debug.Log($"Data loaded with {currentSave.levels.Count} levels");```

for example^

[undone wave]

yeah that's what i did in the update loop above

[wintry quarry]

ok well can you show us the SaveFile class?

[undone wave]

[System.Serializable]
public class SaveFile
{
    public List<LevelSaveDictionaryEntry> levels;
}

[wintry quarry]

honestly the simplest explanation for this is you're just looking at the inspector for a different object than the one that's printing that it has data

[undone wave]

oh yeah i'll check that

[remote folio]

Can I ask you a question about developing the MetaQuest 3 app here?

[undone wave]

oh oof the inspector was displaying the prefab for some reason

Hey folks. I'm trying to make some small effects in my game, namely the game become blander with a vignette effect when close to gameover. I'm using a global volume post process effects for that, however, I have some issues. The color adjustment works but the vignette do not. In fact even in the editor, when I change the intensity, the vignette doesn't appear anymore.
i read in a random post that you are not supposed to dynamically change those values ? What should I do ?

[keen dew]

#💥┃post-processing

[elfin pike]

If I have 30 entities, it would be logical to make script which controls all of them?

[twin cloak]

yea of course if they all follow the same rules, it's common to have a manager that updates/commands them

[elfin pike]

I have multiple NPCs, all of them have same rules, but order different, some of them have to travel longer distances. I think maybe books or enums for state they are in, to easier control in group

[dark hatch]

how can i solve this jiterring?

inputaction is set up normally

collider on obj is disabled

this is the rigidbody

linear damping set to 0 makes no change

[naive pawn]

try setting interpolation

and make sure your camera following is on LateUpdate

[dark hatch]

It's using cinemachine atm, and previously I was using lateupdate to no avail

[naive pawn]

and have you set interpolation

and as mentioned previously, make sure you aren't touching transform anywhere else

[dark hatch]

yes, interpolation does seem to fix it

i set it to interpolate

any idea what the problem could be?

[naive pawn]

the lack of interpolation

[dark hatch]

i've already checked that nothing is calling transform

[dark hatch]

shouldnt that be on by default?

[naive pawn]

i recall it being set by default, but ive seen a lot of people asking without that set, so 🤷

[dark hatch]

alright

thanks

[naive pawn]

is the problem not fixed?

[dark hatch]

no it is

i just didnt know that interpolation was to be on by default

[naive pawn]

ah ok, the way you followed up kinda seemed like it hadn't been fixed

i've seen a ton of people accidentally saying like, "does" when they mean "doesn't"

[dark hatch]

alr ty

[toxic cloak]

hello can anyone explain me is there any way to make the movement less snappy while sprinting if (isSprinting) { rb.linearVelocity = playerControls.MovementInput * playerStats.sprintSpeed; } else if(playerControls.MovementInput != Vector3.zero) { rb.linearVelocity = playerControls.MovementInput * playerStats.moveSpeed; }

i want it to rotate towards the movement input at a speed not instantly if that makes any sense\

[naive pawn]

could make it so you have some acceleration to get up to speed rather than snapping to the speed instantly

there's quite a few ways to achieve that

could use MoveTowards, or use wronglerp, for example

[toxic cloak]

the speed is okay the rotation is just instant

[naive pawn]

that's not affected by the code you showed then

but yeah, same answer really

make it so it isn't instant, use eg rotatetowards

[toxic cloak]

ah yes rotate toward thanks

[solar tusk]

My character moves forward and backward with walking animation. But how can I rotate it left and right.

[toxic cloak]

    transform.forward,
    dir.normalized,
    rotationSpeed * Mathf.Deg2Rad * Time.deltaTime,
    0f
);

 rb.linearVelocity = transform.forward * playerStats.sprintSpeed;```

[lunar axle]

so i have a problem here:

i am working on my unity game and i am want to record the position/rotation of a rigidbody target with 100% accuracy. the problem is my map enviroment changes if i do for the 100% accuracy by tracking of the transform's position then the physics won't work, which leads to them going through walls, doesnt fall... but if i track physics (rigidbody velocity) then it wont have 100% accuracy as the last one. how can i combine the both (aka moving exact position but still have collisions and physics)

[keen dew]

What is it for? Following a target?

[lunar axle]

its for like the playback system

like i record the player's current interaction and they can replay it in the future. think of it as a ghost like this:

https://mariokart.fandom.com/wiki/Ghosts

[night raptor]

Why does it need to be 100% accurate and what does that even mean?

[keen dew]

And if the map changes then how is it a replay if they take a different route

[lunar axle]

no like if the map changes, for example theres a new wall and if the ghost get to that wall, it crashes instead of going pass it.

[lunar axle]

because im doing a parkour game and its very accuracy-sensitive

[night raptor]

I don't understand what you want to happen. Should it or should it not go through the wall? If it shouldn't, how does that make any sense in terms of the replay?

[lunar axle]

I use the term "replay" to explain my current problem im facing bc its similar to the problem im having. Im not really sure what they call it since my english sucks, but what im trying to achieve here is the ghost should not go through the newly appeared wall.

[keen dew]

So if the replay would make the ghost go through the wall, what should happen instead? Should the replay end? Should the ghost stop? Should it go around? Something else?

[rugged beacon]

maybe try record the rigidbody velocity rather than apply position then it should work with physic

[night raptor]

I wouldn't suggest that

[lunar axle]

I tried that but its not really accurate as said

[lunar axle]

Its gonna stuck there except in the past the player moves the character else where

[keen dew]

I think you have to plan that a bit more in detail to make it clear to yourself how it should behave, then it becomes easier to see how it should be coded

[rugged beacon]

fr miss that is it the same with other api too? like .moveposition and such

[lunar axle]

Think of it as a key logger that tracks w a s d keys

[naive pawn]

could do that then

[lunar axle]

Well tried but its not accurate

[night raptor]

Make it accurate then

[lunar axle]

Thats why i choose to record something else in the first place

[lunar axle]

Thats the problem

[keen dew]

I don't see how it would work in practice in gameplay terms. As soon as the character gets stuck it would start going around randomly

[night raptor]

yup

[naive pawn]

if it's frame times that are the issue, you could probably just use the fixed time step

[night raptor]

Most games just have their ghosts simply going through the walls which probably also makes the most sense for the player. Removing the ghost if it goes inside wall would also be in my eyes a better option than it going crazy at the wall

I think also in mario kart (which you showed as example), the ghosts can go through barrels or other movable objects

[sour adder]

I have a replay feature in my space ship game. I record keypresses whenever they change and position and velocity minimum every 0.5 sec if no key-change. It is done with the fixed timestep resolution. It works well with collisions but is still not 100% accurate. I added a special kill-message if the player is killed to make it always work regardless of accuracy of the replay.

[jaunty laurel]

Hey, I'm trying to figure out procedural room generation from preset rooms. Are there any good resources you can point me to?

more specifically im trying to create a grid system that lets me move around points in the editor to dynamically resize the room before I run the game

[night raptor]

What does "moving points" mean and how does that relate to " preset rooms"?

[verbal dome]

If you would use an interface here, it makes more sense the other way around.
Characters have the interface (IGrassRustler or whatever lol). Grass tries to get the interface from the character on trigger enter, and the interface also has a velocity getter if you need.

Doesn't need to be just characters obviously, could be any medium-large object

[jaunty laurel]

for creating the individual rooms, I'm trying to make a script that allows you to move points in the editor to resize the rooms automatically

IE based on 4 coordinates make a room

[night raptor]

I don't understand what that means. What do those coordinates represent?

[wintry quarry]

Can you draw a picture? I.e.:

• Here's the points
• Here's the room it generates

Is it always a quadrilateral? Is it a polygon? What shape should it be? Is 4 points always enough?

your problem is currently underspecified

[charred monolith]

please help i dont know how to fis that

[wintry quarry]

looks like you probably have a duplicated script

[charred monolith]

ok and how do i remove the duplicated script?=

[wintry quarry]

find it and delete it from the filesystem

[swift crag]

you're going to have two scripts in your project that define the same class

If you recently renamed or moved a script, that's probably the offender

[charred monolith]

yea i fixed it. there duplticated script was right undder tutorial info. i prob clicked a button do duplicate it by accident

[fossil linden]

Quick question for beginner programming theres not anything different between unity 2019 and 6.3 right?

[keen dew]

Right, over 7 years they haven't done anything other than changed the version number

[night raptor]

In terms of "beginner programming", it isn't too far off though. Most things haven't changed at all. They have changed like .velocity into .linearVelocity and probably other similar small changes but nothing that would make it hard to follow an old tutorial for example. The new input and UI systems are noteworthy though the old systems still work (would prefer learning the new ones)

[white shadow]

Hiya I'm following this tutorial: https://www.sharpcoderblog.com/blog/creating-a-first-person-controller-in-unity

I plugged it all in and got the first error

The only controller in my project right now is the CharacterController so I plugged that in but that didn't work; what does it want?

[polar acorn]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/GameObject.GetComponent.html
I have no idea why it tells you to just not include the type argument. As far as I know that was never valid in Unity's C#. Maybe it can infer it in the later C# versions that aren't available yet?

But you need to include the type in angle brackets for GetComponent so it knows what type to return.

[keen dew]

I have another theory

[polar acorn]

Ah, better idea

You should definitely not use this website

[ionic oxide]

hi everyone i'm new to the server! i'm a beginner coder making a 2d game in unity, I was wondering, is anyone free to hop on a call with me and help me debug my code? Stuff isn't working and I don't really have anybody to help me haha

[polar acorn]

That's not how things work here. You'll need to actually ask the question here, there aren't any voice channels

[ionic oxide]

ah I see, where do I ask?

[polar acorn]

Here

As I said

[ionic oxide]

alr cool

so basically i'm making this 2d game that has a random map generator, and I wanted to have messages pop up on screen to show the user that they can do something eg. when they are within one tile of a closet a UI message shows up that says "press [E] to hide". I've created something called InteractionUIManager.cs and assigned it to an empty gameobject in my hierarchy but when I run my code it never seems to wake? I added a debug line that tells me if it calls Awake() but I never see the debug message. It is in scene during runtime though.

[verbal dome]

and the thing is called in other scripts with lines like:

InteractionUIManager.Instance.ShowPressP();

[ionic oxide]

yes

[white shadow]

I cant move around in game but I'll see if I can fix that myself first :)

[verbal dome]

And you haven't hidden any logs in the console?

[ionic oxide]

oh shit now that i check it in error pause it does say that the program woke and also called show E, idk why I never got the debug message then

[verbal dome]

Idk how error pause would fix that but good 😅

[ionic oxide]

lol idk either, so apparently the program is running but not doing anything

[verbal dome]

So the ShowPress methods are called but the UI objects are not being set active?

[ionic oxide]

yes exactly

[verbal dome]

If so, the null check fails (or something else is disabling them)

[ionic oxide]

oh

what do I do then 😨

[verbal dome]

Assign the UI objects that are null I presume

[ionic oxide]

they are all assigned tho?

[verbal dome]

Then the null checks don't fail and the objects are being set active 👍

[wintry quarry]

Make sure you don't accidentally have more than one of these things in the scene

and add logging around the behavior that isn't working as expected

[verbal dome]

        Debug.Log("Show E called, UI exists: " + (pressEUI != null));```

[ionic oxide]

ok lemme try

[verbal dome]

It's likely that you have a duplicate of this component yeah

[ionic oxide]

okay i got: Show E called, UI exists: True

but i didn't see the text so now idek what's going on

[ionic oxide]

like a duplicate of pressEUI?

also idk if this means anything but if I stood within range the message kept sending over and over again

[verbal dome]

Yeah, but if you only see one log from Awake then you only have one of them

[verbal dome]

Then it is setting the UI active. How did you confirm that it isn't setting it active?

Maybe it's actually outside the view, or it is being disabled by something else, or its parent is inactive or something

[ionic oxide]

i opened hierarchy while running the game and checked to see if the ui is being set active

if i get rid of LateUpdate() then the UI stays active from the very beginning ...

[ionic oxide]

yh there was only one

[verbal dome]

Wait... I didn't even read the LateUpdate part

Why are you deactivating everything in LateUpdate?

[ionic oxide]

i need to deactivate them at the start no?

[verbal dome]

LateUpdate runs every frame!

[ionic oxide]

oh wait maybe i should have put that in awake

BRUH ALL THIS TIME

I WAS AGONISING WONDERING WHAT I DID

I'm so stupid

i can't this is worse than leaving out a semicolon

[naive pawn]

sounds like a hands-on lesson about why errors are nice to have lol

mistakes will happen - errors are explicit, bugs are silent

[ionic oxide]

lol thank you!! you will probably hear more from me today

thanks @verbal dome

[white shadow]

Got it!

[past cloud]

hey, im trying to make an animation play while holding down the left mouse button, but for some reason the animation only stays on the first frame

        if (Input.GetMouseButtonDown(0))
        {
            anim.SetBool("isAttacking", true);
            Debug.Log("Attacking!");
        }
        if (Input.GetMouseButtonUp(0))
        {
            anim.SetBool("isAttacking", false);
            Debug.Log("Stopped attacking!");
        }

this is my code

this is how my animator is set up

[polar acorn]

Are you getting the "Stopped attacking" log when the animation stops?

[past cloud]

yeah the logs are working as they should, while mouse1 is being held it prints attacking and as soon as i let go it prints stopped attacking

its just while im holding mouse1 it just stays on the first frame of the animation

[polar acorn]

So it's not printing early, but it is ending the animation early?

[polar acorn]

Ah, that's what you mean

[past cloud]

yeah like the animations not even playing

[polar acorn]

Any State means any state

The condition is still true. So it transitions to itself again

[past cloud]

oh

thank you

that fixed it

so it just kept basically restarting itself?

[polar acorn]

Yes

[jaunty laurel]

can anyone help me understand scale in unity?

is there any way to have like a universal measure of size for an object

[wintry quarry]

1 unit = 1 meter

the actual size of an object depends on the actual size of the mesh or sprite, multiplied by its scale

a basic Unity Cube is 1x1x1

and a basic unity sphere has a radius of 1

[wintry quarry]

Can you explain what you mean by this? Like a tool in the editor, or what?

[jaunty laurel]

yeah, like when I'm working on a prefab I dont know how it will relate to everything in my main scene without putting it in and comparing

suppose I have a wall or something, is there a good way to figure out the size of the wall in units rather than scale

[wintry quarry]

that seems like a good way to do it tbh.

[wintry quarry]

(putting it in the scene)

[wintry quarry]

you could make an editor tool perhaps

but the "size" of a 3D object can be vague

[swift crag]

is this a model or a sprite?

[wintry quarry]

like.. how "big" is a cat

You can always use the renderer bounds: https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Renderer-bounds.html

[swift crag]

For models, you should make sure all of your meshes have a consistent scale

[wintry quarry]

but you won't get the same bounds size for a rotated wall as an axis-aligned wall for exampkle

so it's a rough estimate

[swift crag]

the usual convention is 1 unit = 1 meter

Blender defaults to this

[jaunty laurel]

but if im doing something where size needs to match, like I want the width of a wall to exactly match the floor, is there a way to do that without just putting them next to eachother?

[swift crag]

create all of your models with a consistent scale and everything will work out correctly

[wintry quarry]

how are you making the objects?

Use ProBuilder or Blender and then those tools DO have size information available

if you're jsut scaling cubes - well you need to move on to a more powerful tool here.

[jaunty laurel]

right now im importing assets from the unity store, but I will be making them in blender

[wintry quarry]

Blender tells you the size

[jaunty laurel]

got it

[wintry quarry]

Just make sure you import/export at a consistent scale and you're good

[swift crag]

It may be helpful to create prefabs with consistent scales

e.g. you prefab everything to fit onto a 4-by-4 meter grid

[jaunty laurel]

so the size from blender will be transferred if I load in the 3d model

[wintry quarry]

yes although there may be a conversion factor

which can be addressed in the unity import settings or the blender output settings

[swift crag]

blender's default "Apply Scalings" mode (All Local) gives you a model 100x smaller than you may expect

the imported model will be scaled up 100x to compensate

I prefer to use "FBX All" when exporting FBX files

this gets the scale right

therefore, a 1 meter cube in Blender will also be a 1 meter cube in Unity when the model has a scale of 1

[wintry quarry]

Basically I would take one example object from blender - put it in a scene with a unity cube or sphere, and get the size how you want it by changing blender export/unity import settings on it

Then reuse those settings for the rest of your assets

[swift crag]

I spend a huge amount of time bikeshedding the overall size of my models

(models of rooms to be used in a VRC world, I mean)

[hot thorn]

hey guys try this mousemovement script

using UnityEngine;

public class MouseLook : MonoBehaviour
{
public float mouseSensitivity = 100f;
public Transform playerBody; // Drag the parent Player object here
float xRotation = 0f;

void Start()
{
    // Keeps the cursor centered and hidden during gameplay
    Cursor.lockState = CursorLockMode.Locked; 
}

void Update()
{
    // 1. Get raw mouse movement
    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

    // 2. Clamp vertical rotation so you can't look "inside" yourself
    xRotation -= mouseY;
    xRotation = Mathf.Clamp(xRotation, -90f, 90f); 

    // 3. Apply rotation to the camera (Vertical)
    transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
    
    // 4. Rotate the player body (Horizontal)
    playerBody.Rotate(Vector3.up * mouseX); 
}

}

[solar hill]

what?

[chrome tide]

thats really not something you should share here. if you have a specific question about this then just ask

[solar hill]

it also screams "ai generated"

especially because of the comments

[chrome tide]

yeh, the comments

[solar hill]

"drag the parent player object here" yeah bro pack it up

[dark hatch]

yeh lmao

its okay tho

can use ai to get started

[solar hill]

i just dont see the point

[night raptor]

The classic incorrect use of Time.deltaTime...

[solar hill]

lmao i didnt even notice it

[dark hatch]

it feels similar to the vid brackeys made, considering the xrotation variable

[night raptor]

They also fumbled the deltaTime

[dark hatch]

dont really feel like looking at that huge wall of text tbh lol

[rich adder]

thats what happens when you train LLMs on incorrect info engrained on the internet

[swift sedge]

it literally is the exact same apart from the comments

the "first person movement" video

its not AI generated, it's just taken from Brackey's and reposted here

[rich adder]

the comments look suspicious of "AI"

[wintry quarry]

It's AI generated and the AI generated it from the thousands of brackeys clones on github

That deltaTime bug is never going away 😭

[swift sedge]

oh lol

that's why AI fails to think rationally

[polar acorn]

Good ol' Brackeys error

Will haunt us until the day we die

[swift sedge]

too bad Brackeys does Godot tutorials now

[polar acorn]

Now he's their problem

[swift sedge]

I've always wondered why the "mouse sensitivity" was so high

[ionic zealot]

I'm doing a unity project for school and im making an fps, im familiar or.. with unity before the update to it's movement

Now i cant find a good movement script

[wintry quarry]

Before what update

[slender nymph]

!learn 👇 instead of finding something to just copy from, consider learning what you are doing so you can make it yourself

[radiant void]

:teacher: Unity Learn ↗

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

[slender nymph]

but also yeah, movement hasn't really changed in a long time

[wintry quarry]

Any movement script from the last 15 years will basically work the same now as ever

[slender nymph]

literally the only difference is in the input, and even that doesn't require a code change, just a change in the settings that the relevant error message tells you about

[ionic zealot]

What? everything is crashes, I used to add velocity to objects and it never broke, now it does and nothing from videos goes with minimal errors

[wintry quarry]

Wdym "everything is crashes"?

I used to add velocity to objects and it never broke
Still works to this day

the only thing change you might be encountering is renaming rb.velocity -> rb.linearVelocity for Rigidbodies

[ionic zealot]

This was in the video that i used

[slender nymph]

that's because you copied it wrong

[wintry quarry]

this is a simple coding or copying error on your part

this would not have worked 15 years ago either

you also need to get your Visual Studio configured properly so it shows errors

[ionic zealot]

I tried, i have the unity extetions and idk why

[slender nymph]

!vscode

[radiant void]

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[ionic zealot]

why?

[wintry quarry]

Because you messed up. Not sure how to anwer "why"

You copied incorrectly from the tutorial

(whatever tutorial you're using)

[ionic zealot]

But i retyped it, whats wrong? it's late and i need to make it in a day or so

[wintry quarry]

Frankly the code you justw showed us is nonsense

and doens't make sense

Go back to the tutorial and try again

You retyped it incorrectly.

[ionic zealot]

It's preety same

[slender nymph]

now compare that to your own code because it is, in fact, not the same

[polar acorn]

Where do you define _playerInputController in your PlayerController class?

[slender nymph]

and digi is here just in time to tick the counter

[polar acorn]

Pretty same is not same

Close enough isn't enough

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 202
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2026-03-23

[polar acorn]

And no, it is not "pretty same", it's actually almost completely different

There isn't a single thing the same between your PlayerInputController and theirs but the name

[ionic zealot]

Is that a genuine statistic or made up for effect?

[polar acorn]

It is every time I've seen this exact notion repeated by someone with my own eyes in this server

[slender nymph]

we really need a bot for it so that we can get the real count and not just the ones you've witnessed. it would 100% be in the thousands by now

[ionic zealot]

Yea, coding sucks

[slender nymph]

it's much easier if you actually pay attention to the information provided to you

[wintry quarry]

You need a certain mindset for it which right now you don't have. The computer is exacting, it can't just get the "gist" of what you mean.

[ionic zealot]

I am made for farm work, i dont know why i went to cs, it suckss, i could have a ranching job rn

[ionic zealot]

yea, i keep learning every day

I fixed everything i could find, still i get an error

Assets\Scripts\PlayerController.cs(13,31): error CS0103: The name 'inputValue' does not exist in the current context

[slender nymph]

spelling is important. get vs code configured like you were instructed to before

[slender nymph]

and this with extra troubleshooting steps for configuring it: https://unity.huh.how/ide-configuration/visual-studio-code

[naive pawn]

that looks confiugred to me there's also no errors in that code, is there?

[past cloud]

Why is my inspector not creating a sprite list?

[polar acorn]

Do you have any compile errors

[past cloud]

thank you

i did but it was being covered by a warning

so i just ignored the warning

how do i change the sprite an image is using?

[rich adder]

reference the component and replace the sprite property of it

eg mything.sprite = newSprite

[past cloud]

how do i reference an image

getcomponent<image>() doesnt work

[rich adder]

why not

[rich adder]

yes its telling you you're missing the namespace

[night raptor]

Probably using UnityEngine.UI or something

[past cloud]

what is a namespace

how do i make it work

[polar acorn]

Basically a folder for code

But not actually a folder in the file system

It's all those using statements on the top. If your IDE is configured you can usually just click the error and let it auto-import

[past cloud]

oh like an import

[rich adder]

when in doubt also check the docs
https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html

[swift crag]

there are a ton of Image classes, so you have to make sure to get the right one, too 😉

[past cloud]

after putting in using UnityEngine.UI i get this error

[rich adder]

thats just unity editor bugging out its not your code

you can just clear it, restart unity if it appears again

[past cloud]

ty

[rich adder]

ineteresting how even the docs has example code of changing a sprite
https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html#UnityEngine_UI_Image_sprite
granted its old input system but the concept is there

[polar acorn]

General rule of thumb, if the line number is some long hex address in <> you can probably ignore it

Check the stack trace and see if any of those lines are in code you wrote

[rich adder]

also usually coming from UnityEditor instead of UnityEngine

it aint waking up 😢

[dapper field]

What's the "industry standard" way to store player data / repeated item data? I don't want to declare each field at the top of the class every time, but I tried using a scriptable object & it doesn't "feel" right. (i.e. every item has a "value" field for its worth in gold, and a "rarity" field for its rarity, which I don't wanna copy-paste over every time)
The values aren't necessarily the same, just the variable and how it's accessed

[grand snow]

You can have custom editor ui to quickly use presets perhaps to set value or you can have other scriptable objects to assign preset values

[wintry quarry]

Make a class or struct

[grand snow]

But at some point the data has to be defined so sometimes you need to duplicate it

If this is purely about "I keep adding float value to my classes" then learn about inheritance

[wintry quarry]

Although it's a little unclear to me what you ean by "I don't want to declare each field at the top of the class every time" - when is that happening? Can you show an example of the code?

[timber tide]

Classes until later c# versioning

[dapper field]

so like

public class PlayerData
{
  public int money;
  public string rarity;
}

public class Player
{
  public PlayerData = new PlayerData();
  //assume I actually made a constructor or a load system that sets the initial values
}

?

[timber tide]

That and for most cases you want to pass stuff around as a reference

[sour fulcrum]

this feels like inheritance + specifically interfaces

[dapper field]

I kinda just scrapped my entire codebase because I was making things over reliant on each other

[grand snow]

abstraction!

[wintry quarry]

yes - though you can set the stuff in the inspector. (if you want)

If you do this:

[Serializable]
public class PlayerData
{
  public int money;
  public string rarity;
}

public class Player : MonoBehaviour
{
  public PlayerData data; // assign values in inspector.
}```

[dapper field]

thing is that when I do that I have to do

public abstract class PlayerData : MonoBehaviour
{
  public abstract int money {get; set;}
}

public class Player : PlayerData
{
  public override int money {get; set;}
}

so I end up just having to declare it anyway (I get the benefits of having a superclass to refer to instead, I just was wondering if there was a better way to do it)

[wintry quarry]

why do you need to override it?

[sour fulcrum]

you don't need that override

[wintry quarry]

don't make it abstract

You can make it virtual which allows for optional but not required overloading

[grand snow]

Hmm yea I think you miss understood something. I thought you were making say loads of item type classes and duplicating fields/properties.

[dapper field]

I thought that made every child class refer to the same variable then? I don't want player A to share currency with Player B -- unless I misunderstood

[wintry quarry]

you definitely misunderstand

you're confusing types and instances here

[grand snow]

learning time! https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/object-oriented/inheritance

[wintry quarry]

it makes every type that derives from the parent have the same fields, but it doesn't make every instance use a shared dataset

[sour fulcrum]

(statics would do this behaviour)

[wintry quarry]

Yep^

that's what a static variable does

[dapper field]

I forgot that's what static things do

I'm gonna go bang my head against a wall

[grand snow]

tl:dr go learn about object oriented programming properly

dont learn from this chat

[wintry quarry]

Every vehicle has wheels. But that doesn's mean they're all sharing the same pair of wheels

[woven bolt]

Not super new to unity, but can someone help me import an FBX? I can get the model in, just cant get the textures

[wintry quarry]

#🔀┃art-asset-workflow

[timber tide]

Import textures separately

[dapper field]

I learned about static variables years ago
I'm just stupid and I haven't seriously coded in a long time so I'm forgetting basic things .-.

[woven bolt]

ive tried that lol

[dapper field]

Overengineering cause I went down the rabbit hole of scriptable objects too

[woven bolt]

Itd be helpful if someone could guide me through it

[timber tide]

Gltf better if you want full asset import

[grand snow]

Nothing wrong with re learning this stuff! Then you will be in a stronger place to program again.

[dapper field]

yeah I read through this now I just feel stupid xD

[slender nymph]

this is a unity server

[past cloud]

hey, how could i go about making a time stop ability? i basically want to freeze the movement and animations of all entities besides my player

ive seen things about time.scale but it sounds like it pauses everything and i dont want that

[slender nymph]

either make sure they are moving in a way that uses Time.deltaTime and your player is not, or create your own global time scale value that those things use for movement or just an event they subscribe to that will disable related systems

[past cloud]

is there a way i could basically just do like a for loop that runs through the hierarchy and sets the velocity and animation speed of everything else except my character to 0

[slender nymph]

use an event instead

[past cloud]

how do events work

[naive pawn]

it pauses things that rely on scaled time. there also exists unscaled time

[undone axle]

I am using UGS for leaderboards. Whats the recommended way to implement some sort of profantiy or hate speech filter on names?

[rich adder]

ultimately you have to have a system for extra checks because someone who wants to be vile will always find a way. You could at least begin with running the name through some sort of list/file of known profanity words

a library specifically made for this is probably your best bet cause they might contain even variants using numbers as letters n all that

eg https://github.com/stephenhaunts/ProfanityDetector

[undone axle]

I could totally put it in my unity code and list all the bad words... But filling my code with hateful speech seems not cool. I was just curious what people usually do. I don't need to stop all of it. I just want to put in some of the more hateful stuff. I guess I could maybe use cloud code when displaying the names on the leaderboard? Change the bad words to something funny or something?

That way I could just update the cloud code instead of making a new build if I want to change something

[rich adder]

whatever you choose to do the process is the same.
there are online APIs (will probably cost money) you can probably hit that do the same and its not in your code? but this is a library its literally built for this, there isn't some magic to make them change on their own without a reference point lol

[undone axle]

Yeah I guess I am asking where do people usually put the profanity check, at input, at display, in unity, in cloud code, etc

[rich adder]

in most cases before you even allow the input to be saved after the capture of it

look at other media, you usually can't even get passed the user input phase

Oh, and also, when I collide with the object that should cause a screen to appear nothing happens

And I'm thinking it's because it believes that the Object housing the script does not exist thus the script doesn't change anything, even though on other scripts like my score controller it understands and reads variables from the Collect And Destroy script.

[polar acorn]

Something with that script on it was destroyed. It does not mean that there are none in the scene, it means something was referencing one that no longer exists

So, probably your GameOverScreen. Which CollectAndDestroy is that referencing?

[timber trellis]

do people usually create test suites for games, or is everything done manually ?

[floral zealot]

I'm having a very strange issue where it appears that my float variable is presenting two values at once, and I can't use the one I need.
There are two scripts involved here: XPManager, and XPBarManager. XPManager is attached to an empty game object (also titled XPManager), and XPBarManager is attached to another game object (titled XPBar) that has children that make up the entire xp bar as a ui element.
XPManager has a public static float titled xp which is initialized as 0f and is incremented by 1 before invoking an "updateXPBar event".
The updateXPBar event has the XPBar game object tied to it (i don't know the terminology for that, sorry) in order to call XPBarManager.OnUpdateXPBar(). The plan is to use the static xp value from XPManager to update the xp bar ui.
The screenshot attached shows the inspector for XPBar, the noteable code from XPBarManager, and the output of a debugging print line. As you can see, the inspector and console show two different values.
There are no duplicate variable names here. barXp is also a float. I can provide any other info necessary.
Thank you to anybody who takes a look

XPManager shows the correct/intended values in the inspector as well. And XPBarManager has no other methods

Please ping me if you have any ideas!

[polar acorn]

The one you're looking at in the inspector and the one that's logging the number are two different XpBars

[wild cove]

sorry for the late reply but it is referencing the mole's (the cylinders) collect and destroy script

[polar acorn]

Are you sure? If you click on it, does it highlight the one in the scene? Does it stay assigned in play mode?

[wild cove]

Well I'm not exactly sure, when I click on it it doesn't highlight anything for some reason.

and when im in play mode it doesn't even show the error

but something is wrong because when I collide with this one rectangle thing it makes the dead boolean true, but the problem is the other script that should be reading the boolean from the other script isn't properly reading it and won't do anything when the boolean is true

Which is extremely weird because I have another script that references a variable from the collect and destroy script and it workks perfectly showing me the score on the top right.

[floral zealot]

Just wanted to check back in and say thanks, I read this and am investigating

The values in the XPBar and its XPBarManager script seem to update to the correct values after I exit playmode but not during. Does this sound like a familiar issue?

[polar acorn]

Then most likely the thing it's assigned to isnt in the scene. Drag the scene object in again

[polar acorn]

Probably means the one you're reading from and the one you're colliding with are two different instances

[polar acorn]

Are either of these objects prefabs

[floral zealot]

they both are..

dont tell me that's been the issue this whole time

[polar acorn]

You are probably calling the function on the prefab, not the one in the scene

So you're modifying the file, which has no effect on things that already exist but does change what they spawn in with

[wild cove]

What do you mean by this?

[wild cove]

And the object with the script is in the scene for the script

I double checked and dragget it again

[polar acorn]

The one you've dragged in on game over screen and the one you're colliding with are probably two different objects.

Try logging something when this object is hit, and add in the second parameter , this). It will highlight the object that logged it when you click on that log

[floral zealot]

I believe we have sorted out the core of my issue, thank you so much digiholic! I've unpacked those objects from being prefabs and deleted said prefabs altogether, and it works with hard-coded xp, but wasn't working with instatiated xp because of issues with those and events. I think I'll be able to solve it using a spawner parent object which persists, and executing events from there via a method that all of the spawned/instatiated children can call. Thank you for helping me out

[wild cove]

Well, yes they are different, because the capsule is the player and the thing it collides with is the "enemy" (the large box looking thing floating ahead of the cylinder) that will send the person playing to the game over screen, but when it collides with the capsule (I realize that I called it a cylinder earlier, sorry about that, that thing has a completely different purpose) it doesn't do anything, which I know has to be a problem with it not reading the bool from the collect and destroy script because I've tested by putting "game over" in the debug log when the enemy collides with the capsule.

And what do you mean add in a second paramater, to what?

[polar acorn]

To debug log

You can log the one that's changing its bool, and the one GameOverScreen is referencing, and see if they're the same ones

[wild cove]

uhh, sorry but could you give me an example, im kinda dumb

I understand the point

I dont understand how to add this second paramater

[rich adder]

coolmethod(param1, param2, etc.)

time to refresh on basic c#

[wild cove]

That's why I'm in code beginner

I'll watch a video on parameters cuz I don't understand them

So from what I understand parameters tell the computer what you're using in the code??

[rich adder]

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

[wild cove]

Ohh, so parameters are the things that tell you what to put in the method and kind of what the method handles and the method does things to the specific things put in place of the parameters

        }
        if (Input.GetKey(KeyCode.S))
        {
            // Bevæg os baglæns
            transform.Translate(-transform.forward * Time.deltaTime * backSpeed);
        }

        if (Input.GetKey(KeyCode.A))
        {
            // Roter til venstre
            transform.Rotate(-transform.up * Time.deltaTime * rotSpeed);
        }
        if (Input.GetKey(KeyCode.D))
        {
            // Roter til højre
            transform.Rotate(transform.up * Time.deltaTime * rotSpeed);
        }
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Coin")
        {
            Destroy(other.gameObject);
            coins++;
        }
    }
}```

It only works before the cube is rotated with 'a' and 'd'

[shadow briar]

Hello,
So im just trying to make a simple enough damage system for a basic FPS project.
Interface with TakeDmg(float), and Heal(Float)
Health Script, MaxHealth, Current health and all that.

my initial thought was to put the interface on the Health script, and make all the damage logic based around interacting with the Health that has the iDamagable.
Just wondering if it would be better practice to put the idamagable interface on the scripts that are damageable.

So Crate, Player, Hostile as example, have the interface and could have a health script.
I mean as i write i am leaning more towards that - but was still unsure and just wanted more clarity and other opinions.

[sour fulcrum]

That's kinda what i have, where i have IHurtable, HealthBehaviour and two usecases PlayerBehaviour : MonoBehaviour, IHurtable and EnemyBehaviour : MonoBehaviour, IHurtable

and the interface is just

public interface IHurtable
{
    public int CurrentHealth { get; set; }
    public int MaxHealth { get; set; }
}

HealthBehaviour has the actual logic for handling health and whatnot and then stuff implementing IHurtable choose to fufill the interface promises by having a reference to a HealthBehaviour component eg.

public class PlayerBehaviour : MonoBehaviour, IHurtable
{
    [SerializeField] private HealthBehaviour health;

    public int CurrentHealth { get => health.CurrentHealth; set => health.CurrentHealth = value; }
    public int MaxHealth { get => health.MaxHealth; set => health.MaxHealth = value; }
}

[shadow briar]

hm alright, i see, interesting enough approach for me to see and gives a bit more insight in it, thanks for the input.

[sour fulcrum]

It’s one of those things that is pretty project & developer dependent imo so it’s totally valid if you find some version of a solution that’s most comfortable for you

[cerulean badger]

what's the best technical way to make a npc move in 2d top-down?

[keen dew]

As with all other "what's the best" questions, the answer is "there is no best" and "it depends"

[cerulean badger]

makes sense

void SpawnCubicles()
{
foreach (Room room in rooms)
{
for (int x = room.x; x < room.x + room.w; x++)
for (int y = room.y; y < room.y + room.h; y++)
{
if (map[x, y] != 1)
continue;

        // Skip tiles next to walls
        if (IsWall(x + 1, y) ||

            IsWall(x, y - 1))
            continue;

        Instantiate(
            cubiclePrefab,
            new Vector3(
                (x + 0.5f) * tileSize,
                0,
                (y + 0.5f) * tileSize
            ),
            Quaternion.identity,
            transform
        );
    }
}

}

hello im using this code to spawn a cubicle prefab on the tile if the tile fits the criteria

now it fits the criteria correctly and spawns it

but instead of spawning the cubicle in the center of the tile it spawns it on the top right corner of the tile, and uses the pivot of the cubicle prefab to do s

so it looks like this

[timber tide]

You're positioning it with Instantiate so probably get an idea what the offset is doing

[humble summit]

so should i delete the offset?

i don't understand

[timber tide]

0.5f would imply that it's trying to center it, but your prefab pivot not represent that

Well, assuming in units of 1

[humble summit]

so what do i have to do

[timber tide]

mess with the offset or pivot of the prefab

[humble summit]

the pivot is pretty much at the center of the prefab

so thats fine

so i think

offset i need to change

i don't know what i need to change in the offset then

[timber tide]

usually it's more like x * tilesize to get to the cell pivot, then to center you'd do tilesize / 2

[humble summit]

just remove the whole vector3?

[humble summit]

so (x+tilesize) /2

[timber tide]

not the same

[humble summit]

(x* tilesize) /2?

i'm bad at this

[timber tide]

imagine it's the 10th x index, but you can't just say x * 10, because you need to also calculate the unit size

and once you get there, you only want to progress half a tilesize to center it

[humble summit]

could you please type out how it would look like

i can barely do mathematics

[timber tide]

(x * tilesize) -> cell pivot
tilesize / 2 -> half length

so (x*tilesize) + (tilesize/2)

the extra offset could be a negative offset though depending how the grid pivot is setup

[humble summit]

like this?

[timber tide]

sure

I guess there can be 4 different offset variations, (x, y), (-x, y), (-x, -y), (x, -y)

[humble summit]

oh this fucked everything up

majorly

[real thunder]

how bad is the idea to replace mesh of skinnedmeshrenderer on awake out of several veriants for mob look variety?
making a prefab for each random look sound a bit like a chore

[timber tide]

oh hmm

[humble summit]

thanks for helping anyways

i just can't wait till im done with this project

it's a class

where we have to do a solo project

[timber tide]

oh you're using y, should be z

[humble summit]

and i never do programming

[humble summit]

i'll try

[timber tide]

im actually confused now that your original uses y

oh yeah ok you're applying the y offset in the y component, but you want to be using it in the z of the vector

[humble summit]

so i delete y and put in z

[timber tide]

y is up, but your alg uses y to represent indexing

but you're populating on the x/z

[humble summit]

what should i do

fuck it i have bigger problems than this to focus on

[humble summit]

thanks so much anyways

[timber tide]

you're setting the y value in the vector, but it should be the z value

[humble summit]

i really have no idea how to code so i can't change this a lot other than with chatgpt

last time i properly coded was a year ago or more

[timber tide]

Yeah, grid stuff can be complicated, but it's not necessarily a unity thing, but more general coding. It's fun to learn though.

[humble summit]

it would be fun if this wasnt on a deadline

[humble summit]

i'm basically using procedural generation to create dungeon levels

[timber tide]

Unity actually provides some grid class, but sometimes better to just make your own anyway

[humble summit]

one more question

im creating a prefab out of models

how do i set it a pivot

[timber tide]

So meshes you can't set pivots on in unity, but you can wrap them in another gameobject. This parent wrapper can now be to represent the pivot

So making some parent just for transform values

[humble summit]

so i make a little nothing burger object and then place it where i want to be

then parent it

[timber tide]

Empty Parent -> Mesh Child

then you can move the mesh child freely and just reference the parent for the pivot

[humble summit]

what i've came up with now sort of almost looks like i want it too

and thats fine by me

thank you for your help

[sour fulcrum]

please be clear when you use chatgpt, lot of people uncomfortable helping that kind of stuff

[real thunder]

that made me reflect for a moment
I am yeeting some code from github to reuse it while finding some bugs there and flaws and fixing it and it's like close to be a usual thing for me

that's not far from using AI's code is it

[humble summit]

no

it's a thin veil of morality

[twin pivot]

Nah thats called using your brain to find what code would be useful in that situation

[real thunder]

more like typing question into google which did all the search
which is not that different from how AI spit it's code out, it's just less steps

[woven scaffold]

is there an easy way to make a wrapper class act as the value it contains for use in dictionaries?

essentially this:

Dictionary<wrapper, someOtherData> myDictionary = new()
Debug.Log(myDictionary[unwrappedData]) // prints someOtherData

[real thunder]

...scriptable object?

(I have no idea what am I talking about)

[polar acorn]

The difference is a human wrote that code. You can decide if you trust that human based off of their contributions and see if they're likely to know their stuff, and if there is a problem you can notify them and it could be fixed for whoever finds that in the future.

As opposed to an AI that will just lie to your face constantly because it's not actually an information source, it's a digital sycophant

[swift crag]

Yes, actually!

[polar acorn]

I'm not sure what you mean? What you've posted would work assuming unwrappedData exists in the dictionary

[swift crag]

well, you appear to have it backwards here

it sounds like you want to be able to pass in a "wrapped" object and have it treated as the type it wraps

e.g.

Dictionary<int, float> whatever;
whatever[containsAnInt] = 1.0f;

[wintry quarry]

Write an implicit type conversion operator. (Fen just wrote you an example!)

[swift crag]

where containsAnInt is a type like this:

public class IntWrapper {
  private int integer;

  public static implicit operator int(IntWrapper wrapper) => wrapper.integer;
}

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/user-defined-conversion-operators

the compiler will automatically try an implicit conversion operator

(as opposed to an explicit conversion operator, which would require you to do (int) containsAnInt)

[woven scaffold]

yes, though it kinda needs to be like that as the wrapper is what serializes the data. but when i actually use it i dont really care about the serialization class

this is part to make it easier to debug from the inspector for other teammembers

[wintry quarry]

Are you sure you want to put the wrapper itself in the dict instead of the unwrapped type though?

[swift crag]

so you need to index the dictionary with the unwrapped value?

[woven scaffold]

i mean i could just do both, and have one be serialized as its literally only to be able to see it and be able to manually confirm it is what it should be

then just have #UNITY_EDITOR around the serialization

[woven scaffold]

yea pretty much, if not id just do a dumb workarounnd like i said above

[wintry quarry]

This won't work - Unity gets very upset if you have different serialization formats for a type in a build vs in the editor

[woven scaffold]

im pretty sure ive done that before? thats not exactly what i mean, i would basically just make a duplicate field for the data and not another serialization format. then populate the duplicate field thats serialized with the same data. its just ugly as i gotta duplicate it

the runtime logic would never use it and it would be compiled out regardless, but i try my best to not mix editor and runtime code so if possible another solution would be great but idk how that would be or look like

[swift crag]

can you elaborate on this?

[long pasture]

could you not just do a =>

or better just do an onvalidate function
