How?

[eternal needle]

You go the same route as a regular singleton in c#, except instead of creating a new instance, you load it. There should be a few tutorials out there online exactly for this

[nova kite]

is there a way to avoid what they'd probably call drilling when passiing functions to other scripts?

i have a PlayerStats script and there is a TakeDamage method there

and i need to call that method inside the enemy attack state script

and for that to work i have to first call the enemy state machine, over there make a public field for the player state machine assign it in the inspector, call it, make a field to initialize the player stats script there call it and then call the take damage function, that can not be the easiest way to do this lol

StateMachine.playerStateMachine.playerStats.TakeDamage(attackDamage);

[teal viper]

Why does a state machine have a reference to the player state. Why does the player state machine have a reference to the player stats? It feels wrong on many levels.
And where is that code called from?

[nova kite]

that's a lot of code i need to show in order to explain it😅 what's the norm for showing long code here again

using UnityEngine;

public abstract class PlayerState
{
    protected PlayerStateMachine StateMachine;
    protected Animator Animator;
    protected PlayerStats PlayerStats;

    public PlayerState(PlayerStateMachine stateMachine)
    {
        StateMachine = stateMachine;

        Animator = stateMachine.GetComponentInChildren<Animator>();
        PlayerStats = stateMachine.GetComponent<PlayerStats>();
    }

    public abstract void Enter();

    public abstract void Update();

    public abstract void Exit();
}

but this is the player state script

it's a blue print for every state i make for the player

[teal viper]

State machines need to be as generic as possible, not caring about where, when and how they are used at all.

[nova kite]

using UnityEngine;

public class PlayerStateMachine : MonoBehaviour
{
    [Header("Current State")]
    [SerializeField] private PlayerState currentState;

    public PlayerStats playerStats;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        currentState = new PlayerMoveState(this); // Initialize with a default state

        currentState?.Enter();
    }

    // Update is called once per frame
    void Update()
    {
        currentState?.Update();
    }

    // Method to change the current state
    public void ChangeState(PlayerState newState)
    {
        currentState?.Exit(); // Exit the current state
        currentState = newState; // Set the new state
        currentState?.Enter(); // Enter the new state
    }
}

and the state machine handles the states

is that not what i did?

[teal viper]

Why is there a class specifically for PlayerStateMachine how is it different from the enemy. Ideally, use the same state machine by all characters in the game, whether they are players or npcs.

[nova kite]

how would the transitions work tho?

because on the player state machine i call the move state as default

using UnityEngine;

public class EnemyStateMachine : MonoBehaviour

{
    [Header("Current State")]
    [SerializeField] private EnemyState currentState;

    [SerializeField] public PlayerStateMachine playerStateMachine;

    public Transform [] patrolPoints;

    public Transform playerPosition;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        currentState = new EnemyPatrolState(this); // Initialize with a default state

        currentState?.Enter();
    }

    // Update is called once per frame
    void Update()
    {
        currentState?.Update();
    }

    // Method to change the current state
    public void ChangeState(EnemyState newState)
    {
        currentState?.Exit(); // Exit the current state
        currentState = newState; // Set the new state
        currentState?.Enter(); // Enter the new state
    }
}

while here i call the patrol state on default

[teal viper]

This feels very weird. It's unclear who owns what and what "component" in the system is where in the dependency chain. State machine would usually be on top living directly on the character or some other object that updates it. States should definitely not hold onto state machines as fields. At best they could be provided with it in the methods that the sm calls on these states.

[nova kite]

are you saying i studied it all wrong then😭

i spent so much time..

they said you need a blue print for each state

[fickle stump]

Hi!
I'm having an UI Element with buttons, that instantiates an object, depending on their index and attaches said object to my mouse cursor.
What I want to do now, is hover that object over other objects and press left click in the trigger zones (that works fine so far!). What I do need help now, is, how can I swap two gameobjects? My trigger zones contains an object, that showcases the outline of an object which could be placed there, but when i left click on that object i want to delete the placeholder and place the object I have on my mouse! (I do know how to destroy the placeholder object :D)

[nova kite]

a state machine to handle the states

and the states themselves

[fickle stump]

Sorry for itnerrupting you gyus btw

[nova kite]

no worries!

i dont own the channel haha

||(yet)👀||

[teal viper]

Ideally, you should handle the transition in the SM itself, not from outside of it. The SM could query the current state transition, and when the conditions are right, activate that transition.

[nova kite]

wait im not doing that??

 public void ChangeState(EnemyState newState)
    {
        currentState?.Exit(); // Exit the current state
        currentState = newState; // Set the new state
        currentState?.Enter(); // Enter the new state
    }

doesnt this do that

and then i conditionally call the change state method:

using UnityEngine;
using UnityEngine.AI;
using UnityEngine.UIElements;

public class EnemyPatrolState : EnemyState
{
    public EnemyPatrolState(EnemyStateMachine stateMachine) : base(stateMachine) { }

    NavMeshAgent agent;

    int nextDestinationPoint = 0;

    public override void Enter()
    {
        agent = StateMachine.GetComponent<NavMeshAgent>();
    }

    public override void Update()
    {
        if (!agent.pathPending && agent.remainingDistance <= agent.stoppingDistance && agent.velocity.sqrMagnitude == 0f)
        {
            {
                nextDestinationPoint = (nextDestinationPoint + 1) % StateMachine.patrolPoints.Length;

                agent.SetDestination(StateMachine.patrolPoints[nextDestinationPoint].position);
            }
        }

        if (Vector3.Distance(agent.transform.position, StateMachine.playerPosition.position) < 10)
            StateMachine.ChangeState(new EnemyChaseState(StateMachine));

        Animator.SetBool("Walking", true);
    }

    public override void Exit()
    {

    }
}

in the individual states

[teal viper]

Anyways, back to your original problem.

1. You should make a TakeDamage method in the character class(ideally shared for all characters, player or not). Then call character.TakeDamage when youwant to apply damage to a character. The logic of calling the same method in stats should be handled internally to the character.
2. Provide a reference of the character to whoever needs to deal damage to it, instead of letting it get it via a convoluted chain of references.

[teal viper]

Might want to start a thread and provide more details there. Maybe in #1390346827005431951 so that your post is not lost.

[nova kite]

yes but the problem is the enemyAttackState is not attached to any game object and is not a monobehaviour so i can't directly assign things to it

it's only being called by the state machine

that's the only way it runs

[teal viper]

Of course you can. And should be. You can pass data to it in the constructor or some kind of initialization method. For such a state to work properly it would obviously need to know what it's attacking.

[nova kite]

omg right the constructor!

basically like i do here right?

using UnityEngine;

public abstract class PlayerState
{
    protected PlayerStateMachine StateMachine;
    protected Animator Animator;
    protected PlayerStats PlayerStats;

    public PlayerState(PlayerStateMachine stateMachine)
    {
        StateMachine = stateMachine;

        Animator = stateMachine.GetComponentInChildren<Animator>();
        PlayerStats = stateMachine.GetComponent<PlayerStats>();
    }

    public abstract void Enter();

    public abstract void Update();

    public abstract void Exit();
}

passing the animator and playerStats

wait is it good to do that tho if not all state need it?

[teal viper]

That's still not ideal. First of all, I'd avoid passing a character stats around at all. It should be data internal to the character and nothing else should be messing with it.

[teal viper]

It depends. If using a context, it's gonna contain a lot of data that not everything needs.

[nova kite]

i think that script is not properly named tbh haha it just holds a lot of functions😅

oof it's too long to send

    // Method to handle player death
    private void Die()
    {
        Debug.Log("Player has died.");
        // Here you can add logic for player death, like respawning or ending the game
    }

    public int GetCurrentStamina()
    {
        return currentStamina;
    }

    // Method to restore health
    public void RestoreHealth(int amount)
    {
        if (currentHealth >= maxHealth)
        {
            currentHealth = maxHealth; // Cap health at 100
            return;
        }

        currentHealth += amount;

        PlayerUI.SetHealth(currentHealth);
    }

for example

from PlayerStats

// Method to take damage
public void TakeDamage(int amount)
{
    currentHealth -= amount;

    PlayerUI.SetHealth(currentHealth);

    if (currentHealth <= 0)
    {
        currentHealth = 0;
        Die();
        return;
    }        
}

// Method to use stamina
public void UseStamina(int amount)
{
    currentStamina -= amount;

    if (currentStamina < 0)
        currentStamina = 0; // Prevent stamina from going below 0

    PlayerUI.SetStamina(currentStamina);

    lastStaminaUseTime = Time.time; // Record the time when stamina was last used
}

[teal viper]

I mean, there are many issues I can point out. But I feel like at this point it would mean rewriting most of your project.

[nova kite]

should i transfer all this logic somewhere else?

or is only the name of the script misleading

i think this mess happened because i discovered state machines only after doing all of this haha

[teal viper]

Player stats should deal with player stats. There shouldn't be "die" and similar methods that are related to the character as a whole, not just it's stats. "Die" in the context of stats is just setting health to 0. Nothing less, nothing more.

[teal viper]

Rather than naming issues, you're mixing the responsibility of your components(not unity components).

[nova kite]

i only did that because i initiazlied all the variables in the same script😅

    [Header("Player's Movement")]
    public float walkSpeed = 5f;
    public float runSpeed = 10f;
    public float crouchSpeed = 3f;

    [Header("Player's Forces")]
    public float gravity = 10f;
    public float jumpForce = 5f;
    public Vector3 velocity;

    [Header("Player's health")]
    private int maxHealth = 100;
    private int currentHealth;

    [Header("Player's stamina")]
    private int maxStamina = 100;
    private int currentStamina;
    private float lastStaminaUseTime;
    private float StaminaRegenerationRateTimer;

    [Header("Player's UI")]
    public PlayerUI PlayerUI;

    [Header("Mouse")]
    public float mouseSensitivity = 2f;
    public float lookLimit = 45f;
    public float rotationX = 0f;

so i said might as well make the methods here to access them

[teal viper]

Accessing a stat is fine. It's part of the stats object responsibility

[nova kite]

i meant accessing easily in the same script haha

[teal viper]

Ah, right it's called player state. This is definitely a misleading name especially since you're using it around state machines.

[nova kite]

instead of froma different script

nono PlayerStats

i also have a PlayerState

which is this:

using UnityEngine;

public abstract class PlayerState
{
    protected PlayerStateMachine StateMachine;
    protected Animator Animator;
    protected PlayerStats PlayerStats;

    public PlayerState(PlayerStateMachine stateMachine)
    {
        StateMachine = stateMachine;

        Animator = stateMachine.GetComponentInChildren<Animator>();
        PlayerStats = stateMachine.GetComponent<PlayerStats>();
    }

    public abstract void Enter();

    public abstract void Update();

    public abstract void Exit();
}

this one is clean haha

[teal viper]

Why is it a state even? What does it represent logically? Can a character transition into or out of it? So, like can a player become an enemy?

[nova kite]

no this is the blue print for every player state

its all abstract

which from my understanding forces every script inhereting from it to have these methods

while also being able to pass it thigns via the constructor

[teal viper]

Then maybe a StateDefinition or something is a more appropriate name. But then again, I'm not sure why you need it in the first place.

[nova kite]

thats true haha

[nova kite]

could you share where you learned state machines i might be overcomplicating it😅

i learned it from a few videos

i was lost at first too

[teal viper]

It has less to do with state machines and more with OOP principles, like single responsibility and encapsulation.

A state machine is really just a a system that switches between states. Everything else is an extra.

[nova kite]

hmm so it's more about C# than Unity?

[teal viper]

Not C# even. The same applies to many OOP languages

[nova kite]

So if i want to have a greater understanding of it i should look up C# OOP videos?

oh it's handled the same?

[teal viper]

Yes.

[nova kite]

across languages

i see, thank you!

i thought it's a Unity thing lol

[teal viper]

Yes. It's all logic. Unrelated to how you write it down.

[nova kite]

Thank you!!

that clears things up

[teal viper]

A big part of it comes from experience, but learning the OOP principles can get you started.

[nova kite]

i barely ever scratched the surface with that so it will defiitely be helpful!

[twilit slate]

Sorry for interrupting, can someone help me really quick. I've been trying to make a rocket league type game and ive been trying to make a system where the goal effect color can change depending on which side it lands. But it just refuses to change color

[eternal needle]

!code but also you clearly have errors in console. those could easily be affecting whats happening here

I have just solved them and the particles still dont change color

[polar acorn]

Is the issue that the color value in code isn't being passed correctly, or is it something with the material that's not working? Try logging the color after you set it. See what value you're setting it to.

[twilit slate]

I have no idea. Because everylast script has the effect refrence. but every attempt I make to change the color doesn't work. It just stays white.

[polar acorn]

So, did you check?

What did the log say

[twilit slate]

I don't mean to be annoying but how do i have it log the color

I'm not good at this i'm sorry

[teal viper]

Debug.Log

[digital parcel]

guys so now i wanna see what my main camera prespective looks like but idk how to change it, now my game section i mean the circle sign one its showing backgroundcamera prespective but i want it to show main camera prespective like the arrow one

do you guys know how to change it?

[twilit slate]

Its not even changing

[frosty hound]

Drag the scale slider at the top of the game window all the way to the left.

Also consider not using Free Aspect mode and changing it to 16:9.

[twilit slate]

Another log says I "Don't have access" to the material too. but the material still doesn't change when I put it to shared material

[polar acorn]

So, what does the log say is the color that you're setting the particle color to

[twilit slate]

Red

[digital parcel]

ahh the problem is just the camera deept number thanks for ur help bro 👍

and yeah i've scale it to 16:9

[polar acorn]

Does it say the word "Red"?

[twilit slate]

My bad. It says this

[polar acorn]

Okay, so that's more what I was expecting. This shows you're not using values in the 0-255 space and that your alpha is not 0. Where in the code are you logging it? Send it via !code instead of a video this time

I believe you'll need to set the color via the particle system itself, not by accessing the renderer.
https://discussions.unity.com/t/how-do-i-change-particle-system-color-via-script-in-unity-5-6-1f1/188736

The start color of the particle system is just gonna change it as soon as you play it

[twilit slate]

Thank you. I'm sorry for how i am, Unity is very overwhelming for me

[nova kite]

It's very overwhelming at first but you get used to it, the best thing you could do is follow the official Unity tutorials on their website it gives you an incredible base

[odd holly]

how do I fix this?

[rich ice]

get rid of system.numerics or just manually pick which one you're using by typing out the full name

[naive pawn]

why do you even have Numerics imported

it was probably a suggestion that you accidentally accepted?

[odd holly]

I figured it out using google

I forgot to check back here before google Im sorry 😭

[nova kite]

anyone knows why am i still taking damage even tho im not withing the collider?

what this does is calling this script on a specific frame of the enemy's animation and it's calling this overlapSphere function to see what it would collide with and then check if one of them has the player tag

but even when im outside of range that i visualized for debugging it tags me

[sour fulcrum]

Have you chucked a debug log in that function

[nova kite]

logging what?

[sour fulcrum]

That it happened

[nova kite]

it all works perfectly the only problem is that i still get hit when above it

you can see the healthbar in the video haha

[sour fulcrum]

Means nothing to me

[nova kite]

i can show its code

it calls this function

from another script

[teal viper]

Add logs. If you see it printed twice when it's supposed to be once, look at the callstacks

[sour fulcrum]

You claim your still taking damage even though your not in the collider

that means

A. you are in the collider
B. something else is giving you damage
C. some other weird thing etc.

you need to narrow down what exactly is happening in order to determine why it should or shouldn't be happening

[nova kite]

i see, lemme see what i could add

could the size of that sphere be off even if i pass it directly in the code?

[brazen oxide]

maybe your collider's size is bigger than the actual object?

[sour fulcrum]

your a step too ahead here

[eternal needle]

you add logs to see whats going wrong in the first place

[sour fulcrum]

log to see if the sphere check is even running ^

[nova kite]

ohh

[eternal needle]

also dont use ?. on unity objects

in that hit.GetComponent

[nova kite]

oh does that not check for null?

[sour fulcrum]

it's a weird unity quirk-ish

[nova kite]

oops haha

[eternal needle]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Object.html

The null-conditional operator (?.) and the null-coalescing operator (??) are not supported with Unity Objects because they cannot be overridden to treat detached objects objects the same as null. It is only safe to use those operators in your scripts if there is certainty that the objects being checked are never in a detached state.

[sour fulcrum]

just dont use that ? syntax on UnityObjects (monobehaviours, scriptableobjects etc.)

it's a relatively niche thing and easy to not know

[nova kite]

oh god i gotta change it in so many places XD

[eternal needle]

it seems the docs were updated because it never stated when its safe to use before, although it was already kinda obvious

[nova kite]

i used it in the state machines too😭

[eternal needle]

but either way I wouldnt use it because you could think its safe while its not, leading to hard issues to debug. for consistency sake too

[sour fulcrum]

easy to fix in a little bit

[eternal needle]

well you literally just dont need it in some of those cases. How is your currentState ever null when its private and immediately set on Start?

this is literally not possible to be null

[nova kite]

i added it everywhere just in case hahaha

cuz i hate the if (!null) it's too bulky XD

[teal viper]

Is currentState even a MonoBehaviour or unity Object?

If not, then it's fine to use ?

[nova kite]

how is this for logs?

[sour fulcrum]

A little much but more is better than less

check the problem and see what logs run or dont run

[nova kite]

ohh it's not

[eternal needle]

!code also, this is a pain to copy for writing examples

all passed

[sour fulcrum]

is that what should happen

[nova kite]

yup! the script runs it hits all nearby objects

finds the one with the player tag

and gives it damage

[sour fulcrum]

did the problem occur

[nova kite]

when i jump above it? lemme see

same logs when jumping above it

[sour fulcrum]

is that what should happen

[nova kite]

and only these logs when running away from it

so the problem seems to be only vertical

[nova kite]

nope you should be able to outjump it

vertically

[glossy carbon]

Good morning everyone

[sour fulcrum]

I mean more literally

[nova kite]

and it even takes the max verticality correctly 1.5

[glossy carbon]

new Nooby question 🙂

[eternal needle]

Imo its also pretty bad to throw in checks everywhere just to avoid errors. Ill use the state machine as the example but this applies to everything. in your state machine, do you explicitly want to allow a null state where an enemy cannot do anything? this seems like the game would be in a broken state if this was possible, yet your code would not notify you of this when testing because theres no error

[sour fulcrum]

you tested scenario 1: not jumping, logs reflect intended behaviour
you tested scenario 2: jumping, do logs reflect intended behaviour?

the thing with this kinda issue is it doesn't really "matter" what the code is actually doing, it's narrowing down if the code is doing what your want it to do or not

Your either failing to tell it to do the right thing or your succeeding in telling it to do the wrong thing

[glossy carbon]

I have added these to a sprite of a space station that im trying to make collision detection for a space ship but its not working and my spaceship just flies right over the top :s. Ive watch a bunch of vids and looks on forums but im missing something still

[nova kite]

ohhh wait it wouldnt give me a null error??

[glossy carbon]

sorry im sure this is simple to you guys but i just cant seem to see what ive missed

[sour fulcrum]

errors are good

[nova kite]

omg right cuz im not assigning anything in the inspector XD

[nova kite]

yea but this would be a silent one hahaha

[sour fulcrum]

if something needs to not be null hiding the problem away with a null check doesnt fix it

sometimes the cars gotta crash if its broken

[eternal needle]

Of course not, youre checking if its null using ?.
Which wont call the function if it is null

[nova kite]

ill just remove them haha, but any ideas for the sphere?😅

[sour fulcrum]

again you gotta look at your logs

[nova kite]

does the spaceship also have a rigidbody

[sour fulcrum]

whats happening that shouldnt be happening
whats not happening that should be happening

i mean this code wise

[nova kite]

but it's all perfect from the logs🥲

[glossy carbon]

ye this is what i have for the spaceship

[sour fulcrum]

what does that mean

[eternal needle]

You said it yourself, its not working when vertical. How is it perfect from the logs if logs are printing when they shouldn't

[nova kite]

that it's all giving the values im expecting

[nova kite]

because it gives the max value 1.5

vertically

Debug.Log($"Y difference to shockwave: {yDifference}, max allowed: {maxHeight}");

[polar marsh]

I am waiting for bros pfp load😭

[nova kite]

is there no different way to do this btw

like just using the on collider enter🥲

or is it not possible with the OverlapSphere

[nova kite]

try to delete the rigidbody from the space station maybe, i didnt really do 2D physics stuff before😅

[eternal needle]

The spaceship also needs a collider. If it has one, then you'd probably want to show how its moving

[nova kite]

oh wait

should it be kinematic

[glossy carbon]

Im not sure what you mean by i want to show how its moving ? do you mean you want to see the script?

[nova kite]

i think he means like literally how it's moving in the game

that you said it wont collide

[eternal needle]

The script yes, but first does it have a collider?

[glossy carbon]

you nailed it the ship needed a collidor

[nova kite]

oh lol

[glossy carbon]

its working now thank you

can you add more than one collider to sprites?

as i want the space station to have docking areas but i need a collider with a trigger to run a script right?

also is there a way of only seeing the spaceship so i can adjust the collider without all the busyness on the screen?

[silk night]

select it, then press shift + h

also if you want the icons there removed, you can temporarily turn off gizmos at the top right above the scene view

[odd holly]

How do I fix this...?

[sour fulcrum]

conditions dont use ;

[odd holly]

you and my friend responded at like the same time

Im just dumb...

[glossy carbon]

Brill thank you

[bright zodiac]

except switch expression and ternaries

[naive pawn]

i mean those aren't exactly exceptions, just different contexts

it's not that conditions don't use ;
it's that control flow statements take 1 statement and a ; can serve as that statement

not a code question, #💻┃unity-talk

[bitter charm]

ok sorry

[native flame]

is the character controllers isGrounded check essentially useless or do I just not know how to use it?

[silk night]

it would be beneficial if you describe what issues you are having with it

[naive pawn]

make sure you move down with gravity every frame

the isGrounded check basically checks if it hit the ground, not if it's currently near the ground

so if you don't apply gravity, it's basically hovering 0 units above the ground and not actually on it

[native flame]

hmmm okay, thanks for the tip

rn i only have gravity applied if !isGrounded

ill try it out

[silk night]

But yes, many people use alternative solutions to this, either doing a raycast down or a spherecast at the feet of the player

[teal viper]

I'd avoid using character controller at all.

[native flame]

im guessing spherecast is superior to raycast here? in that a raycast would return not_grounded when youre standing off an edge

[silk night]

yes, in that case it would be better, really depends on your game

[naive pawn]

which one is "superior" depends on your intent and the possible level layout

[silk night]

if you have a flat world and you just want to check if you can jump again a raycast is fine, if you have edges your suspicion is right

[reef patio]

the animator is being hard on me for a 3d character

[native flame]

did u say please?

[hexed terrace]

This is a code channel. If you need help with animation, then use #🏃┃animation

[reef patio]

Something broken.

I'll go there.

Thanks.

[odd holly]

my little smooth brain cant understand what Im supposed to do...

[frail hawk]

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

[north kiln]

You have declared InputDirection in a different scope than where you're using it

Also, local variables should be camelCase, not PascalCase

[odd holly]

...what does that mean...?

[teal viper]

You need to learn C# basics.

[north kiln]

https://unity.huh.how/programming/other/scopes#block-level-scope

[odd holly]

yeah but Im doing this for a game jam so I dont really have timeeeeeee

[frail hawk]

so you are making a game without knowing how to make one

[teal viper]

Why are you doing a game jam without knowing basics..?

[odd holly]

Im learning as I go

it worked before

[teal viper]

Then take your time

[odd holly]

I was in another game jam before and it turned out well

[teal viper]

Well it doesn't seem so.

[odd holly]

This is the tutorial

Im pretty sure I have the same thing as it

So I don’t know why mine isn’t working

[north kiln]

You don't

[odd holly]

The pm is because they were talking GetSlipeMoveDirection from the PlayerMovement script but I just coded the Slide in the PlayerMovement script from the start

I don’t know if that messed it up or not

[frail hawk]

can you show the whole script as code

[odd holly]

I can show my code but not the video

[frail hawk]

yeah, that

[odd holly]

The whole script or just the part Im talking about?

The whole script is like 300 lines so I don’t think it’ll fit in a discord message

[frail hawk]

I dont know why it copied like that

[frail hawk]

this doesn´t help, it is missing the important part you are talking about

[odd holly]

It is…?

[frail hawk]

just use a code bin

[north kiln]

Presumably because you failed to paste it between the backticks. Use a paste site instead.

[odd holly]

Every time I click copy and paste it puts it as a .txt

[north kiln]

use a paste site instead

[odd holly]

how do I do that...?

[frail hawk]

scroll up and read what the bot posted

#💻┃code-beginner message

[north kiln]

I've already pointed out the problem and linked a resource, but it seems to be ignored in favour of this

The code in the magenta scope has no idea about the code in the blue scope

[odd holly]

so how do I make them know about eachother...?

[north kiln]

You don't

[odd holly]

I put the code in the website thing

now what do I do...

[north kiln]

You declare things in an outer scope if two inner scopes need to use them. As the code in your tutorial has done

[odd holly]

I think Im just blind because I literally do not see any difference between the tutorial and my code

[north kiln]

You click save and copy the new url

[odd holly]

Besides the pm

[odd holly]

The website url?

[keen dew]

How do you think are these even remotely similar

[odd holly]

does the pm thing really matter...?

I thought that if I just put all the code in the folder it was reffering to I wouldnt have to deal with that

[keen dew]

the other line

[odd holly]

there is not way Im this much of a dummy...

Im just blind

[frail hawk]

you are not blind you just have to read what people and the dyno bot post

and before diving into game dev, at least learn a few basics of c#

[odd holly]

Hmm…. This is the toughest game of spot the difference ever…

Now I really dont know the difference

    {
        if (!OnSlope() || rb.linearVelocity.y > -0.1f)
        {
            rb.AddForce(InputDirection.normalized * SlideForce, ForceMode.Force);
        }

        else
        {
            rb.AddForce(GetSlopeMoveDirection(InputDirection) * SlideForce, ForceMode.Force);
        }
    }```

really only difference I see is the pm.

[north kiln]

And now what's the error

[drowsy flare]

I'm using the ColorCurves class in a Volume, to change the look of my game.
It all works well when configuring the TextureCurve from the editor. But I just can't understand how to configure it from code. Any ideas?

Edit: nvm sorted it

[odd holly]

The name 'InputDirection' does not exist in the current context

[north kiln]

And where is it declared

[odd holly]

idk what that means 😭

Im very bad with vocabulary

[wintry quarry]

int x;

This is a variable declaration

All your variables need them

Where is that done for InputDirection?

[keen dew]

Now you just removed the Vector3 InputDirection = ... line instead of moving it in the right place

look at the tutorial, find where it is there, and put it in the same place

[odd holly]

it isnt...

[wintry quarry]

Sounds like a problem!

[odd holly]

maybe thats the problem...

[north kiln]

And hence that's why it says it doesn't exist

[odd holly]

because it doesnt!

[exotic cypress]

guys i have a problem that do not print my text in unity's console.

[slender nymph]

is that component attached to a gameobject in the scene

they're passing a string variable

[odd holly]

I didn’t realize what they did

I didn’t read the full thing just the end

[odd holly]

This makes sense

You have to have it attached to something in the scene

[slender nymph]

*in the scene, not just in the project

hence why i specified "in the scene" in my question

[exotic cypress]

so what should i do to fix it?

[odd holly]

I forget vocabulary

[odd holly]

Put the script on an empty or a cube in the scene

I think that would work

[slender nymph]

you should consider going through the pathways on the unity !learn site to actually learn how to use the engine

[odd holly]

Now Im even more confused

I don’t have any errors but the thing it’s supposed to do isn’t happening

its supposed to make it where when you slide down a slope it doesnt do this wierd bouncy thing

but its still doing it

    {
        if (!OnSlope() || rb.linearVelocity.y > -0.1f)
        {
            rb.AddForce(InputDirection.normalized * SlideForce, ForceMode.Force);
        }

        else
        {
            rb.AddForce(GetSlopeMoveDirection(InputDirection) * SlideForce, ForceMode.Force);
        }
    }```

what difference

The only difference I see is the timer which Im 99% sure is optional and the pm. which I dont think I need

because pm. refers to the PlayerMovement script because the tutorial used two seperate scripts but I just put the slide code in the PlayerMovement script because I didnt think it would change anything

[naive pawn]

debug some values and check the flow to make sure it's what you expect

[odd holly]

I have no idea what that means Im sorry 😭

I am very bad at vocab

[silk night]

what IDE are you using?

[odd holly]

Visual Studio Code?

[silk night]

!vscode

[eternal falcon]

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

[silk night]

set it up properly and then you can attach the debugger to unity

so you can see values of variables in real-time

[naive pawn]

looks configured to me, what are you seeing that says it's not configured? 🤨

[silk night]

was just a general note, if he has never debugged theres a good chance that isnt set up

[naive pawn]

you can look at the token highlighting to see if it's configured or not, it seems configured already.

[silk night]

im not familiar with vscode, so no idea

[naive pawn]

it's the same thing in VS

not sure about rider though

[silk night]

just wasnt sure if highlighting is maybe working by default
and yeah im using rider, so neither familiar vs nor vsc 😄

[naive pawn]

i can't actually find examples of unconfigured rider in this server lmao

[silk night]

cause rider brings plugins by default, its basically made to use with unity 😄

[odd holly]

yeah its configured, but for whatever reason it always just immediately fails the second I click debug even though everything is set up the exact way all of the tutorials do...

[naive pawn]

no it's for .NET

[silk night]

now, yes, it started as an IDE for gamedev

[silk night]

what do you mean with "it fails"?

[naive pawn]

you could also just use Debug.Log to check stuff

it's less flexible but less setup

[odd holly]

it just stops and says Failed to attach debugger at 127.0.0.1:56516

I got a debug session earlier

but its just breaking now

[silk night]

also a video or something would be good to see what it does rn, "this weird bouncy thing" sounds ominous 😄

[sharp mirage]

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

how would i implement a 1 second cooldown to using this coroutine

my brain aint working rn

[naive pawn]

use mp4 so it embeds

[odd holly]

wait Ill turn it into an mp4

[naive pawn]

several ways

• set a timer that ticks down
• set a variable that you reset after some time
  and there are several ways to do either of those as well

[silk night]

https://docs.unity3d.com/ScriptReference/WaitForSeconds.html

[naive pawn]

it's [mask](link) or [mask](link "hover text"), btw

[silk night]

yeah i typed something and then pasted that over it, instead of pasting over it converted the old text to a link title 😄

"new" function of discord

[naive pawn]

new "function" of discord

i really want to be turn that off lmao

[odd holly]

its supposed to go smooth down the slope

[silk night]

then i would first check the result of the GetSlopeMoveDirection

[odd holly]

the guy in the tutorial said it supposed to do the bouncy thing and gave the fix but I implemented the fix and its still doing it 😞

[sharp mirage]

oh yeah i could just add another wait for seconds at the end

whoops

thanks

[naive pawn]

oh you're following a tutorial?

make sure you're following it accurately then

[silk night]

there is so many discord things i would want to turn off 😄

[placid bay]

hey everyone, im trying to make a 3d movement system and i almost have it working my only problem is when walking or jumping into the side of an object the player physics doesnt work very well as it will float or not move side to side. to fix this i added a physics material that removed friction from the block and this worked great but i only want it to affect the side of the object and not the top so i can still walk on it fine. or if someone thinks there is a better way of doing it the please lmk, thank you in advance.

[raw tulip]

Everytime I commit to my branch on github then another person merges, it always causes merge conflicts n blows up the repo, is this a common problem in game dev or is this my issue?

[slender nymph]

sounds like you're modifying the same files at the same time which is usually something you'd want to avoid. but you should also make sure you set up your repo to use unity's unityyamlmerge tool to help with handling merging yaml files (like scenes and prefabs)

#1157336089242112090 would be the right location to post about version control related issues though

[grand snow]

Merge conflicted scenes can sometimes be merged manually but often not so making use of prefabs more helps

[raw tulip]

Would making backup prefabs and working on those be a better move?

[grand snow]

I have done this before where I make a duplicate, pull changes, resolve using theirs and copy/re do my changes

[silk night]

Just a tip, if you know you are working on 2 parts of one scene, put both parts in a prefab and work on the prefabs, the scene just keeps the reference so it doesnt care about changes in its child prefabs

[grand snow]

There is this tool from unity to merge yaml but I never got it to work

[sharp mirage]

yo i added a wait for seconds like u suggested but i want the console to log that its on cooldown for that duration if they do try to roll again an if statement for that is all i need right

[silk night]

before the isRolling = false, your if already checks for that one

[grand snow]

https://docs.unity3d.com/6000.1/Documentation/Manual/SmartMerge.html

[sharp mirage]

ahh yeah

and then under that i can do my if statement right?

[silk night]

your input handling already checks if isRolling is false and doesnt do anything otherwise

[raw tulip]

Ty ❤️

[sharp mirage]

yea but lets say the player is trying to roll again but its on cooldown for that 0.5 wait period

[silk night]

yeah the variable turns to false AFTER that 0.5s allowing the player to jump again AFTER it

or do you want to buffer the jump?

so if he presses in that 0.5s he waits until after the cooldown and then jumps?

[sharp mirage]

nah none of that i just want the game to let the player know that they cant roll in that 0.5 period until its done if they do try to do so

a buffer isnt a bad idea tbf

[silk night]

do you want to put out a warning sound / message to the player?

[sharp mirage]

yep

[silk night]

you can do that in the else branch of your input if

[sharp mirage]

alright

[silk night]

unless you only want to show it in the 0.5s, that method i described would output it during the whole jump if the player presses again

[sharp mirage]

like so?

[silk night]

then it would output also if the shift key is not pressed 😄

do else if (isrolling == true) (pseudo code)

[sharp mirage]

oh yeah

well

[odd holly]

Yeah this singular bug that people will barely ever even run into has taken like 2 hours of valuable ass game jam work time so Im just going to move on

[sharp mirage]

rolling being true doesnt necessarily mean that its on cooldown right

because what im doing is just yield waiting 0.5 seconds after ive reset the collider size

[silk night]

it means the player is currently rolling OR its on cooldown

[sharp mirage]

yep

[silk night]

oh then you can work with a new variable that says isRollOnCooldown

you set it to true before the 0.5s wait, and false after

[sharp mirage]

could do

but hold on why did u suggest to put the wait for seconds before is rolling = false

should it not be at the end

[silk night]

because in your current version you can roll again once isRolling = false

so it wouldnt wait for the 0.5s

[sharp mirage]

ahh yeah

[silk night]

You can either work with a 2nd variable as I said above or you can implement a simple state system for the roll

basically a variable that contains an enum:

    public enum RollState 
    {
      Ready = 0,
      InProgress = 1,
      OnCooldown = 2
    }

    void Update()
    {   // If roll button is pressed and player isn't already rolling start the roll coroutine  
        if (Input.GetKeyDown(KeyCode.LeftShift) && playerattributes.rollState != RollState.InProgress)
        {
            if (playerattributes.rollState == RollState.OnCooldown)
            {
              // Notify player roll is on cooldown
              return;
            }
            StartCoroutine(Roll());
        }
    }

    private IEnumerator Roll()
    {
        playerattributes.rollState = RollState.InProgress;
        playerattributes.PlayerCollider.size = new Vector2(originalsize.x, originalsize.y / 2);
        yield return new WaitForSeconds(playerattributes.RollTimer);
        playerattributes.rollState = RollState.OnCooldown;
        playerattributes.PlayerCollider.size = originalsize;

        yield return new WaitForSeconds(0.5f);
        playerattributes.rollState = RollState.Ready;
    }

[sharp mirage]

im not familiar with enums and state systems tbh

ill look into them

[silk night]

enums are easy to understand, you can see it as "names for numbers" and you store that number in a state property, then you can react on the current state

[sharp mirage]

yep

kinda feels like boolean with extra steps

[silk night]

a boolean with more values 😄

what i did above cant even really be called a state system, its a very very simplified

[uncut echo]

Hello, can someone help me pls ? I'm my second prototype / learning game, with actual movements in 3D. Getting this error:
Assets/Scripts/InputManager.cs(8,13): error CS0246: The type or namespace name 'PlayerMotor' could not be found (are you missing a using directive or an assembly reference?)

Code:

using UnityEngine;
using UnityEngine.InputSystem;
public class InputManager : MonoBehaviour

    private PlayerInput.OnFeetActions onFeetActions;

    private PlayerMotor motor;

    void Awake()
    {
        playerInput = new PlayerInput();
        onFeetActions = playerInput.OnFeet;
        motor = GetComponent<PlayerMotor>();
    }

        onFeetActions.Enable();
    }
    private void onDisable ()
    {
        onFeetActions.Disable();
    }
}

[slender nymph]

do you have a component called PlayerMotor

[silk night]

also your FixedUpdate, OnEnable and OnDisable methods are capitalized wrong, just as a sidenote

[slender nymph]

seems like a case of unconfigured !IDE

[eternal falcon]

[uncut echo]

I don't understand one thing:
A component is something I "add" in an object, right ? But my script is not linked to anything. SO I need to add the PlayerMotor "in" the script ?

[slender nymph]

that is a gross misunderstanding of what is going on here. you should stop what you are doing and follow the beginner pathways on the unity !learn site (after you've configured your IDE of course)

[uncut echo]

alright, thank you

[polar acorn]

What is a PlayerMotor

[uncut echo]

a component I guess ? xD

[polar acorn]

You wrote it, what thing were you trying to get when you made a variable of type PlayerMotor?

[uncut echo]

A script that handles the player movement system ?

[polar acorn]

And what script would that be

[uncut echo]

Im so dumb 😂

I thought it was a Unity module

[slender nymph]

here's a fun fact: the name of the script file has nothing to do with the class inside. your class is not named PlayerMotor

[silk night]

After seeing the other script, i am betting $5 on a capitalization error!

[slender nymph]

that or it's still named NewBehaviourScript or whatever the default name is

[uncut echo]

It was my "public class" that was called "NewMonoBehaviourScript". ty guys

C# is so different than other languages

[silk night]

looks like i lost $5 to you 😄

[slender nymph]

it's really not. even other languages you still need to use the correct names for things

[uncut echo]

I mean in the logic

[slender nymph]

logic is the same across all languages because logic does not fundamentally change

😌 😮‍💨

[vital vault]

how to get mouse pointer position like that

[slender nymph]

for what purpose

[vital vault]

i want to make a check if pointer is near boundaries

[silk night]

its usually 0-1 based, not -1 - 1

[slender nymph]

you just need to convert from screenspace to viewport coordinates

[silk night]

i mean with simple math you can get the other range, but i dont see a reason 😄

[slender nymph]

but it would give 0-1 not -1 to 1

[vital vault]

it wounld not matter

[shell sorrel]

what you want is viewport coords they are 0 to 1 but you can easily remap to -1 to 1 if needed

[sharp mirage]

i did end up implementing the second variable u suggested but i decided there should only be a cd if the player doesnt become grounded during the roll timer wait, how would i implement that?
https://paste.mod.gg/zcfdudnpqihr/0

[silk night]

https://docs.unity3d.com/ScriptReference/Camera.ScreenToViewportPoint.html

And if you really want -1 to 1 you can convert it easy:

value = value * 2 - 1

[silk night]

isGrounded implementation is a whole topic for itself, look into that and if you have trouble you can ask here

Also you will still display the "Roll is on cooldown" right now whenever you havent pressed left shift 😄 cause that fails the if condition

[sharp mirage]

alright cool

[sharp mirage]

changed the statement to this but now whenever i press left shift in the logs i just get the message

[silk night]

yeah because thats what your if does? if leftshift is pressed + the other conditions it prints the message 😄

also for a float, never check if its == or != a specific number

always do greater than or smaller than checks with <, >, <=, >=

oh wait, your last condition will never be false because of what i just wrote, you subtract Time.deltatime from it, you are below 0, not exactly 0

[sharp mirage]

oh so i could just do <= 0

[silk night]

yes

well in the case of the message you want > 0

because you wanna check if there is still some cooldown time left

[sharp mirage]

👍

[rocky wyvern]

what are we meant to do for concave colliders on an rb?

I just want a physics enabled bowl lol

[silk night]

you can break the mesh up into multiple smaller colliders

there are also assets in the store that do that for you automatically, not sure if there are any free ones though

[shell sorrel]

not too hard to break up a shape in blender to a bunch of convex ones

you just end up with a lot of edge shapes making up concave curves

[rocky wyvern]

is for a sphere where you want it somewhat accurate

for like a box sure

[polar acorn]

You don't. You make multiple convex colliders

[gray rivet]

im so confused whats wrong with this code 😭

[rough granite]

Well first of all you shouldn't add Time.DeltaTime to AddForce

Secondly you are applying 2000 "force" each fixed frame without input meaning your player is moving uncontrollably each fixed frame

[gray rivet]

oh no i changed that in the variable tab

down to 300

[rough granite]

It's still moving uncontrollably each frame cause its outside of an input statement

Unless that's intended

[gray rivet]

and why not?, i know it sounds pathetic but im going off a vid tut and its saying to do that

[rich adder]

which video ? the video is wrong

[rough granite]

Well the video is wrong

[gray rivet]

i think i know why

[rich adder]

AddForce is already moved on fixed ticks

[gray rivet]

embarrassing

[rich adder]

the time isnt relevant. bad tutorial is a bad tutorial regardless

[rough granite]

AddForce already has its own fixed time and you have it in FixedUpdate witch is also fixed time

[gray rivet]

this is his and its working perfectly fine

[rich adder]

another garbage brackys tutorial, what a surprise

[rocky wyvern]

problem now is I can't use an icosphere cut into the individual triangles because the unity convex hull conversion needs at least 4 verts :))))))))))))))))))))))))))))

[rough granite]

Again its still wrong

[gray rivet]

whats fixed time

[rich adder]

https://docs.unity3d.com/Manual/fixed-updates.html

[rough granite]

Just a word i used (probably the wrong term) to define that the number of frame you have dont affect the speed

[gray rivet]

okay i got it

so let me see if i can try and fix this myself

wit hur help obv

idk what im saying

[rich adder]

its very simple, just remove Time.deltaTime from all the AddForce calls.. this way the numbers also don't have to be cranked up so high

[naive plank]

Hey! I'm using unity's animation rigging package in combination with normal animations. Since im using the rig building I can no more rotate the whole armature in the players local space, how would I go abound replicating the same effect?

[rich adder]

#🏃┃animation

[naive plank]

mb

[gray rivet]

what else would be making this not work? (sorry for being a pest im just really new)

[rich adder]

you have to explain what "not work" means ?

also the second addforce is going to keep running if D is not pressed

[gray rivet]

is that big enough

[rich adder]

its explaining to you whats wrong, you're using the Old input system but its not enabled in the Player Settings

You'd have to go and switch it to Both, or OLD only, to be able to use Input class

[gray rivet]

Where can i change that

[rich adder]

In Player Settings like it said

[gray rivet]

i think i found it

[polar acorn]

I feel like we should get a bot command for that one

Since they changed the default input type it's like 90% of the questions here any more

[gray rivet]

which one would you recommend,does it matter

[rich adder]

Put it on Both for now so you can actually learn that since most tutorials will still have that system

[gray rivet]

yeah that makes sense

[rich adder]

in time you should learn the new input system though, its far better and not that much more difficult

[gray rivet]

where can i find stuff on it?

thanks man, this will not be the last u will be hearing from me

[hot wadi]

If I use OnTriggerEnter or OnCollisionEnter in a parent object with Rigidbody, does it automatically detect collision on all child objects with colliders?

why not test it out for yourself ?
those colliders become part of the rigidbody so its likely

Just made myself a working tech demo, it’s largely 2D but I want to have a minigame in another scene in a 3D world space. I read it’s possible but I can’t make heads or tails of it, no matter what I do the camera still appears to be in a 2D mode

[hexed terrace]

Don't use an ortho camera

switch it from ortho to perspective

No that’s the first thing I did, no change

This should be a great resource, I’ll play around with it when I get home. Thanks a million : )

I’ll be sure to post in the right channel if I have issues. Posted in here cause I saw there might be a code component to it

[rancid tinsel]

any idea why the removing bit doesn't work? trainLength points to the value that I'm changing, so there definitely are more trainCars than trainLength, yet they're not being removed.

[umbral bough]

Hey, I am testing Unity 6.3 and noticed that I have to explicitly do this now in order for the default map to be active:

InputSystem.actions.actionMaps[0].Enable();

I am positive this wasn't the case in 6.0, am I mistaken?
Again, it's the default map that should be project wide.
If this is a bug, where should I report it?

[rancid tinsel]

nvm I was only calling it when there were less cars 😭

Hi all, I'm looking at building a dynamic bullet impact system, simply put if a bullet/raycast hits a type of object, a certain type of impact/decal is played/placed (at the moment my prototype is using tags), but I need to to also work on a terrain and be dynamic based on the terrain layer the bullet/raycast hits.

Would anyone have any pointers, or a resource (tutorial etc.) on how to achieve such a thing please? I'm not really sure what the search term should be for el goog

[rich adder]

I've seen people use the texture / some type of mapping with that to play specific sound based on texture/material (this was for footsteps but I'm sure the same concept applies)

[ruby python]

Yeah, that's what I was thinking. The problem is, everything I've found ONLY applies to terrain, and I can't see how to apply it to gameobjects etc.

But, typically, I have just found something from llam academy and seems to look like what I want to do.

https://www.youtube.com/watch?v=kT2ZxjMuT_4

[rich adder]

ya tbh its even easier on materials/ gameobjects than terrain so you're covered then, their videos are good so i'm sure that will work well

[ruby python]

Yeah, it's looking promising so far.

[nimble apex]

if i want function A to always listen and execute whenever function B is called, i use events rather than action right?

trying to use event approach as it can be less expensive?

[grand snow]

both are the same

events are better because then anything can subscribe to be notified when "event a" happens

[naive pawn]

events are just a specific use of actions

[nimble apex]

i have an implmenetation actually

    public override void OnNetworkSpawn()
    {
        InputManager.Instance.EnableControl();
        MoveInput += InputManager.Instance.joystickCore.OnDrag;
    }
    
    private Action<PointerEventData> MoveInput = (PointerEventData evt) =>
    {
        Vector2 input = InputManager.Instance.joystickCore.Direction.normalized;
        if (input == Vector2.zero)
        {
            input = InputManager.Instance.playerInput.Player.Move.ReadValue<Vector2>();
        }

        Debug.Log(input);
    };```

u can assume timing has no issue and ignore backend/network stuff, that isnt important here

[grand snow]

public event Action MyEvent; 😃
public Action MyShitEvent; 🙁

[rich adder]

ya use event keyword

also prevents outside classes from invoking this

[nimble apex]

ok

ohhhhh i see it became pink now

[naive pawn]

what theme makes it pink?

[rich adder]

and make it public otherwise no one can sub to it 😆

[grand snow]

event keyword enforces certain restrictions making it more reliable for event usage

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

[nimble apex]

i think i actually messed up then

this is actually "callback"

[rich adder]

and now you got a cool Lightning bolt

[grand snow]

best reason

[rich adder]

how do you mean? events are callbacks

[grand snow]

fancy list of function pointers

[rich adder]

"calling back" some code through delegate

[nimble apex]

    public void OnDrag(PointerEventData eventData)
    {
         //use event data (onpointerdown)
    }```

you can treat this as void start()
```cs
    public override void OnNetworkSpawn()
    {
        InputManager.Instance.EnableControl();
        MoveInput += InputManager.Instance.joystickCore.OnDrag;
    }```

```cs
    private event Action<PointerEventData> MoveInput = (PointerEventData evt) =>
    {
         Debug.Log(input);
    };```

i still need to invoke moveinput right? even if its registered to OnDrag(), like the debug log inside wont call if i dont make invoke somewhere else?

btw moveinput doesnt even need pointer event data, im making it 1 param only because if i dont do that i cant register action to OnDrag

[grand snow]

you can use a anonymous func to sub

event += (blah) => OtherFunc();

[nimble apex]

MoveInput += (PointerEventData evt) => InputManager.Instance.joystickCore.OnDrag(evt);```?

[grand snow]

can be the other way too im sure you can figure it out:
event += () => OtherFunc(null);

[half lantern]

hi, i'm making a multiplayer game. Currently, I have a time manager script which has public events. It handles the game time and invokes the events at the right time. Right now, there are 8+ events. Lots of different scripts have subscribed to each event. Is this bad practice? If so, is there any alternative?

[shell sorrel]

seems fine

events is way better then having it calling stuff all over

[half lantern]

isnt that high coupling or something (im not sure what its called)

[shell sorrel]

just keep in mind even if the objects are disabled the events still will get called

also coupling will happen, its just controlling where it is

[grand snow]

well duh

[rich adder]

how do you know its the "right time" you'd wanna test this with multiplayer tools that can simulate long latency

[half lantern]

the time manager has a variable for the time, and when a certain amount of time has passed, it invokes an event

most of the events are invoked on the server but some on the client. for the ones on the client, i send a client rpc to invoke them

[stoic summit]

https://pastecode.io/s/brq9775q

hi, this code works as intended, just looking for a peer review so I can improve if possible. Meant to be a code based alternative to unity's in built animator because I hate its guts.

[nimble apex]

somehow it works but the action seemed executed 2x more times?

[grand snow]

Did you subscribe multiple times?

Subscriptions remain until you unsubscribe manually OR set the whole event to null

[nimble apex]

    public override void OnNetworkSpawn()
    {
        InputManager.Instance.EnableControl();
        MoveInput += () => InputManager.Instance.joystickCore.OnDrag(null);
    }

    private void Update()
    {
        MoveInput.Invoke();
    }```

[grand snow]

seems a bit pointless in that example

[half lantern]

when you guys program large projects how do you make ur code clean. do you follow a set of rules?

[half lantern]

omg are you making a multiplayer game as well

im a beginner to netcode but im trying to make a mutliplayer game

[nimble apex]

interfaces make similar scripts that has similar features to maintain strong consistency

extension methods breaks a core scripts into smaller pieces

prefabs and SO make good templates and objects/data ready to use

[half lantern]

thank you so much

[nimble apex]

we can assume

InputManager.Instance.joystickCore.OnDrag()```
cannot reference
```cs
MoveInput()```
or it will take me lots of efforts and loc to reference each other

data only available and generated on OnDrag()

[grand snow]

if the event subscription is external to the class declaring it then it makes sense

[nimble apex]

i think im confused by the concepts at first place

i want MoveInput execute itself once whenever OnDrag() is called everytime, so it should be 1 on 1

moveinput should not invoke by any code other than OnDrag() execution

[grand snow]

I have a class button with the event "OnClick". other things can then subscribe to the event to do stuff when the button is clicked. This is great because Button does not need to know about the other code

You have done it backwards 😆

[nimble apex]

if i invoking it on update when its binded with onDrag() , when onDrag is active

its 1+1 : 1+1 , then it will be 2 on 2?

i think so lol

[grand snow]

you are invoking the event MoveInput which will CALL () => InputManager.Instance.joystickCore.OnDrag(null);

[nimble apex]

😭

[grand snow]

joystickCore should instead have an event such as "OnDragged" that you invoke when OnDrag() is called so then OTHER things can react to OnDrag() calls.

public event Action OnDragged;

public void OnDrag()
{
  //drag stuff
  OnDragged?.Invoke();
}

something else can know when OnDrag() is called and do stuff

[nimble apex]

IT WORKED😭😭😭

ty 👍

[grand snow]

hopefully that makes more sense to you now

[nimble apex]

yeah

[vital vault]

how to make buttons clickable even with Time.timeScale = 0?

[grand snow]

animations?

if using unscaled time it will work normally

[vital vault]

i need for them to work even if time is paused

i want to add pausing to my game

[grand snow]

Yea but I dont think their functionality changes with time scale, animations may be afffected if using scaled time

[vital vault]

ok nvm its my buttons

Hey, Im new to unity so watching some basic tutorials, i have a problem tough, When i create a new c# script my script generates with less code then it does in the tutorial. How do i fix this? I know i could type the missing stuff out manualy but it would save time and be a lot less annoying if i dont have to
Im not getting functions like start and update and it dosnt generate with monobehavior

public class Test
{
    
}

[polar acorn]

Create a MonoBehaviour, not an empty C# script. They're two different menu options.

[rich adder]

you're creating a plain C# script

[trim burrow]

Ah, okay thank you guys!

[half lantern]

Has anybody here looked at galactic kittens sample for unity netcode?

If so, how did you use it as a learning resource?

[rich adder]

there is soo much abstraction that its a pain in the ass. not reccomend, imo the bitesized sample are a bit better

[half lantern]

like 2D space shooter?

[rich adder]

thats one of them sure, if you combine all of them you get a pretty good understanding how to approach each problem you want to solve

[half lantern]

how should i use them tho? just read through the code

[rich adder]

well yeah and how specific things are handled

[half lantern]

how did you learn unity netcode

[rich adder]

there is no like step by step or anything, unity did not handle netcode like that . Maybe the intro on docs, but to a point thats understandable you need a minimum amount of exp before doing multi

the docs kinda walks you through each samplea nd what its purpose is
https://docs-multiplayer.unity3d.com/netcode/current/learn/bitesize/bitesize-introduction/

[half lantern]

ok thank you

[rancid tinsel]

is there any way to get a Vector3 position of a random point in an area?

[rich adder]

default answer to everything : Yes

[rancid tinsel]

true lol

[rich adder]

there are several ways to do this. Also you have to consider what kind of area

[wintry quarry]

What shape area?

[rich adder]

if circular there is Random.insideSphere

or if you want something boxy Random.Range or colliders etc.

[rancid tinsel]

any - in my case it would probably just be a flat plane (its meant to be a waiting area that a navmeshagent goes to, rather than a single point)

[wintry quarry]

It's different depending on the shape you want so you'll have to pick one

[rancid tinsel]

plane it is

[wintry quarry]

for a flat plane you'd just use Random.Range twice

once for x and once for y or z

to pick a coordinate

that's all

If the plane is not axis-aligned, you'd pick a random point in local space like that and then essentially rotate it with either Matrix4x4 or a rotate Transform using TransformPoint

[rancid tinsel]

wait so what should I reference for the area, the transform?

[wintry quarry]

not sure what you mean specifically

you could also do it with Lerp if you define the plane by two corner points - it depends how you want to define the plane

[rancid tinsel]

so ive got the transform reference, and then when i want to get a random point within that transform, what do i call?

[wintry quarry]

well the Transform doesn't have points "within" it

you'd have to provide extra information like the extents of the area you want a random point within

Where is the Transform's pivot in relation to the random area?

[rich adder]

bounds or colliders work also

[rancid tinsel]

i am so completely lost

im asking whether its a collider, transform or what should be the type for the area? im guessing collider if transform doesnt have points

[rich adder]

eg new Vector3( Random.Range(xMin, xMax), etc..
eg new Vector3( Random.Range(-collider.bounds.size.x, collider.bounds.size.x), etc..
not working code just example

[rancid tinsel]

that seems to do it!

[wintry quarry]

"type for the area" is just a really vague description. I'd imagine something like this basically:

public Vector3 SelectRandomPointOnPlane(Transform pivot, float width, float length) {
  Vector3 randomLocalPoint = new(Random.Range(0, width) - width /2f, 0, Random.Range(0, length) - length 2f);
  return center.TransformPoint(randomLocalPoint);
}```

it just really depends how you want to define this area

[rancid tinsel]

yeah thats my bad - trying to describe something i dont understand is tricky haha

[wintry quarry]

there are many, many ways to do it

[wintry quarry]

drawing a picture can sometimes help

[rancid tinsel]

oh true - ill try to remember that for next time

[grand snow]

not everything is a video on yt.
a pre made system like inky may be best

[frail hawk]

but you said 3d , how are you going to handle that

[rich adder]

Ink . Imo

[frigid sequoia]

Am I dumb? Is this not valid?

[slender nymph]

what does the error(s) say

[frigid sequoia]

That the syntaxis is wrong???

But no?

[slender nymph]

what does it actually say, not a vague paraphrase of the error

[subtle sedge]

ty!

[frigid sequoia]

"," was expected

[subtle sedge]

thanks!

[polar acorn]

You can't use a lambda expression for a field variable

[slender nymph]

and is this at the class level? because you've declared a read-only property which naturally cannot be a local variable

[warm palm]

Just went to open Unity today to continue my "roll a ball" tutorial and I'm met with this message:

[frigid sequoia]

What?

[warm palm]

Anyone know what this is?

[frigid sequoia]

I just want to have a shortcut call to that reference

[polar acorn]

You can only use the => notation for functions or properties

[slender nymph]

are you trying to declare a property for the class or are you trying to declare a local variable

[frigid sequoia]

How do I do that?

[polar acorn]

not fields

[polar acorn]

If reinstalling doesn't fix it you probably don't meet the system requirements

[warm palm]

RTX 3070, 32gb ram, AMD Ryzen 7 5800H with Radeon Graphics

[warm palm]

It won't reinstall also

[polar acorn]

Then your OS is probably borked

[frigid sequoia]

I am trying to make a local variable for that field?

I think??

[warm palm]

I have Windows 11 Home that came with the computer brand new

[slender nymph]

well the Type Identifier => value; syntax is how you delcare a read-only property. perhaps you should double check the characters you used and make sure they are correct 😉

[frail hawk]

can you show your singleton?

[slender nymph]

why? their issue is a syntax issue because they added an extra character

[polar acorn]

I'm... not seeing it actually

[slender nymph]

what they wrote is supposed to be a local variable but they've used the syntax for declaring a read only property. removing a single character turns that into a valid declaration for a local variable
||>||

[warm palm]

It just stops here

and says this

[polar acorn]

Wait is it a local variable or is it a property

[rich adder]

#💻┃unity-talk btw this is a code channel

[polar acorn]

Yeah probably OS related. If it can't install the program at all that sounds like a windows thing

[slender nymph]

it's supposed to be a local variable which is why they are seeing the error. if it were declared at the class level then there wouldn't be an error because it's valid syntax for writing a read only property
(it's valid expression body syntax for a read only property)

[rare topaz]

Is there a way to scatter prefabs onto a terrain (like the literral prefab, not just the mesh attached, like the scripts and everything)

[warm palm]

So unity doesn't work properly on windows or are you saying my windows has something wrong with it

[polar acorn]

Yeah spawn it a bunch

[polar acorn]

I'm saying your OS is borked somehow if you can't even run the installer

[rare topaz]

With three ?

[polar acorn]

three what

[rare topaz]

The paint tree tool ?

[warm palm]

Do you have any idea how to fix this I know it's OS related not Unity technically but everything else works fine on here literally only unity that's had an issue

[polar acorn]

Do you want trees or full objects

[rare topaz]

full object

[polar acorn]

reinstall windows

[warm palm]

ok

[polar acorn]

Then call instantiate on it a bunch where you want it to be

The point of terrain tree instances is that they aren't full GameObjects

[rare topaz]

there is no already premade script for that ? ;-;

[rare topaz]

then what's the difference between placing tree with the grass tool and the tree tool ?

[polar acorn]

Different parameters

I tried just deleting the unity hub folder completely and then running the installer and it installed fine and works now

[tidal lagoon]

I need help finding out how to look at objects from the left in the scene I have a video

[polar acorn]

Position the camera on the left

[tidal lagoon]

can I send the video

because its hard to explain

[frigid sequoia]

Doesn't really have much to it, it should be matching, I am not sure what I am doing wrong

[frigid sequoia]

Like this is basically what I am doing right? I don't get it....

[slender nymph]

how do you declare a local variable

like just as an example, declare a local variable of type int and assign it a value in the same line

[tidal lagoon]

private float variable = 1f; is this what your asking

[silk night]

yeah well, then send the video 😄

[frigid sequoia]

Like just this??

But this is not really pointing to anything

[slender nymph]

there you go. you even fixed your issue

notice how in both cases now you are using the assignment operator = and not the expression body operator =>

[slender nymph]

i was not asking for help there lmao

[silk night]

are you asking how to rotate around the object?

[frigid sequoia]

But like I don't want the new variable to be equal to the thing, I want it to point to the thing so I can modify the thing from there

[slender nymph]

wdym by "modify the thing"?

because even if it were a property you still wouldn't be able to change the object referenced in that variable you used in the assignement

[tidal lagoon]

so when I press the top right thing it at 11 seconds, it looks at the left but flips it, I want to be looking at the left of the object and orbit around it as if I'm looking at all the sides. An example is walking around a chair and facing it

[slender nymph]

you would still only be able to modify its public properties/fields

[silk night]

It always goes to an upright view

press F to focus the object, then you can press alt + left mouse button to rotate around it

[polar acorn]

What do you mean by "normally", that seems pretty normal?

[silk night]

it does, your perspective is rotated

+y is usually up

[tidal lagoon]

when I mean normally I mean walking around a chair and looking at it

when I look at the left wall of the cube it rotates it or flips or something

ive seen a video where the person is looking at a object and is flying around it while facing it

[silk night]

thats because you are standing sideways in the room looking at the chair 😄

you start looking at the cube from the top, ofcourse it flips when you then switch to the side

[tidal lagoon]

yeah, how do I make it not do that and look at the cube like the video

[silk night]

can you send your first video again?

[polar acorn]

It still seems like you're just doing normal camera movement so I'm not sure what the issue is

[silk night]

your up arrow is not pointing up

[tidal lagoon]

what do you mean

[silk night]

the way the arrows point is backwards, not up

[tidal lagoon]

according to the youtube video, am I doing what the guy is doing 7 seconds in

[polar acorn]

I literally do not see anything wrong with this

[silk night]

he is wondering why the rotation is behaving weird, its because his cube is rotated wrong

[rich adder]

is this local or world ?

[tidal lagoon]

nothings wrong with the movement I just want to know how to look at it without making it flip the camera and stuff

[tidal lagoon]

I dont know what that means but I havent messed with settings so its the default

[tidal lagoon]

local

[marsh vale]

idk why mine doesnt work

does it have to do with outdated tutorials or something

[rich adder]

that syntax u wrote is nonsense

[silk night]

this is how it behaves if you have the orientation right

[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: 191
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2025-07-31

[silk night]

this is how it behaves if you have the orientation wrong

[ivory bobcat]

Yours isn't the same

[ivory bobcat]

They've underline where you've made a mistake

[silk night]

you basically start looking at the cube from the top, then flipping over to the left, which causes the view to flip

[tidal lagoon]

how do I fix the orientation

[silk night]

your cube is flipped on its side right now

make sure on the cross top right the green Y arrow is pointing up

and then rotate the cube so the upside of the cube points the same way

[tidal lagoon]

this will fix the scene camera

[silk night]

yes

[tidal lagoon]

Thanks

[sweet pendant]

Yo who knows how to make a grabbing system, like making a system where you can grab a box or smth

[wintry quarry]

Lots of people know how to make one.
Do you have a specific question?

[sweet pendant]

Yes

How do u make one

[wintry quarry]

Usually using raycasts

[sweet pendant]

Can someone post a code here so I can understand

[wintry quarry]

Like any problem you'll need to break it down into parts:

• Detection of an object in range in front of the player
• The "grabbing and holding" part

[wintry quarry]

just posting arbitrary code won't help you much. Basically:

• For the detection of the obejct you would use a raycast
• For handling the input, you would use normal input functions like Input.GetButtonDown
• For holding/grabbing, you would either teleport the object to a specified position in front of the player each frame, or use physics e.g. setting velocity to move the obejct towards that point each FixedUpdate

[polar acorn]

"Grabbing system" is not the most granular way to express this idea. Make it smaller and more specific. Amnesia, Half-Life, Super Mario World, and Donkey Kong Bananza all have "Grabbing systems"

[sweet pendant]

What if you use Vector3.distance to check how far it is from player and then mouse down so you can grab it instead of using raycast

Does it work

[polar acorn]

[wintry quarry]

It would work if you want to grab objects anywhere in a spherical area around the player and if you want it to be really inefficient (because you'd have to do that distance check for every grabbable object in the scene), sure

if you want to only be able to grab objects you're looking directly at, you would use a Raycast

[sweet pendant]

K thanks man

Ill try doing these things

[thorn kiln]

Oh dear, what's happened here. This exact same code worked fine in a previous project.

Ah, I see

[polar acorn]

I don't believe it did. GetButtonDown has always expected an InputManager button name

[thorn kiln]

Yeah, just noticed that

Auto-complete can screw you sometimes

[wintry quarry]

You're confusing GetButtonDown and GetKeyDown

Rather than setting the transform position for all 4 bounds to keep something in bounds, is there a way to keep something within the bounds of a plane?

Cause all I'm looking to do is keep the ball within this square plane, so I'm wondering if there's an easier way to do that

[native seal]

you could use OnTriggerExit maybe?

[teal viper]

The latter is usually better.

[native seal]

and make a big collider

[thorn kiln]

Hmm, I was wondering if there was data in the plane I could use

[native seal]

what do you mean data in the plane?

[thorn kiln]

In my brain I'm just thinking there has to be data that tells unity where the planes X and Z axis stop, but maybe I'm just making that up and all it knows is it's position and scale

[teal viper]

You could probably check against the plane bounds(x, z) in code and prevent the ball from going outside them.

[teal viper]

If it's just an empty object, then yeah. But renderers and colliders have bounds.

[native seal]

if you want physics wouldn't invisible colliders just be easier though?

[umbral parcel]

Could someone help me about the game scale?

once i put it on full screem it got like this

[thorn kiln]

Yeah, it's got a mesh collider. How do I find info on the bounds for it?

[native seal]

.bounds usually

for all things with geometry

[umbral parcel]

but when i keep it on the editor it stays normal

[thorn kiln]

Hmm, this might be too ambitious for my current skill level

[native seal]

what exactly are you trying to do? make it bounce around the edges?

or if it touches the edges it stops completely, are you using physics?

[thorn kiln]

Nah, make it so it can't go past the edges

[native seal]

so the 2nd one?

no physics

[thorn kiln]

I'm using transform.translate for x and y, but I'm using addforce for jumping

If that matters at all

[native seal]

so you want effectively "invisible" walls?

[thorn kiln]

Yes

[native seal]

simplest way is just make invisible boxcolliders around the edges

but it can be easily done using the bounds of the meshcollider of the plane

[thorn kiln]

I'd need to see how it's written to understand

[native seal]

in an update loop you would check the position of the ball and compare it to the world bounds of plane, if they are over then set the position of the ball to the edge

but you would have to account for the radius if you dont want clipping, etc

[thorn kiln]

Probably too complicated for me right now. Someone should help Okane instead 😂

[native seal]

i would just make boxes around the edges 😂

[thorn kiln]

Probably easier, but I like the idea of precision

[native seal]

no reason they aren't precise?

[native seal]

something is wrong with your CanvasScaler component

[thorn kiln]

I could also make it precise with transform.position, but I liked the idea of something that would adapt if I made the plane bigger, and also wouldn't require me to make 4 if statements and 4 variables

[umbral parcel]

yeah it wasnt sacaling with screem size

[native seal]

colliders would need 0 code haha and using EdgeColliders would be super easy

wait maybe edge colliders are 2d only

[thorn kiln]

Yeah, I suppose, but I'd also like to be able to code the solution. Putting an invisible block in the way feels like the easy way out 😂

Like how they couldn't get trams in fallout working so they just make the tram a helmet and attatched it to an NPCs head 😂

[native seal]

you could make a meshcollider and invert the normals so it acts like walls, that would require code

it could also be super easily resized to the plane size in code

[thorn kiln]

I'll probably leave it then since I don't understand some of those words yet

[native seal]

haha, you could always ask AI to give an example to understand the code

[polar acorn]

Colliders need not have mesh renderers.

Spawn an object, put a box collider on it, scale it to the size you want and you're good

[thorn kiln]

GPT gave me something, but I'm probably getting lost in the weeds here

[native seal]

i just dont see why you need to do something that unity physics already does and probably does better

if its the resizing, you could make a simple script that resizes the boxes exactly to the borders of the plane

[thorn kiln]

How can I explain this....
Imagine someone only knows how to do addition
You ask them to get the result of 6 lots of 10
They'd just say "10 + 10 + 10 + 10 + 10 + 10 = 60"
And then you're like "you know multiplication is a much better way to do that?"
And the asnwer is no, they don't, because they don't know multiplication yet

[native seal]

i understand but in this case that multiplication is not only much better but its much easier than addition

if you insist on using code you would do what I said above

[shell sorrel]

just use physics or if you want to control the transform directly just get the bounding box of the plane and use that compute your movement limits

[thorn kiln]

And yet, this is what I actually understand how to do at my current level.

        if (transform.position.x > xBounds)
        {
            transform.position = new Vector3(xBounds, transform.position.y, transform.position.z);
        }
        else if (transform.position.x < -xBounds)
        {
            transform.position = new Vector3(-xBounds, transform.position.y, transform.position.z);
        }
        else if (transform.position.z > zBounds)
        {
            transform.position = new Vector3(transform.position.x, transform.position.y, zBounds);
        }
        else if (transform.position.z < -zBounds)
        {
            transform.position = new Vector3(transform.position.x, transform.position.y, -zBounds);
        }```

[shell sorrel]

https://docs.unity3d.com/2022.3/Documentation/ScriptReference/Bounds.html

all colliders and mesh renders have a property to get these bounds

getting xbounds then -xbounds makes no sense and would be just wrong or twice what you want

also instead of using if's using Mathf.Clamp will be much easier to read

you can construct a new vector where the x and z axis are clamped using the max and min x z and z of the bounds

[native seal]

is there something complicated about putting walls around then making them invisible that i dont see, not trying to be rude

[odd holly]

I need some help

[thorn kiln]

Not really, but like I said, it's coding that I don't understand, I already know how to put a big invisible box in the way to stop something, that's easy, but I don't really learn anything from doing it

[native seal]

ah i see

[thorn kiln]

Blame unity tutorials for teaching me to do things that way

[shell sorrel]

not everyones game uses physics directly even in a heavily movement based game i am doing for work all movement is our own logic

[odd holly]

I was coding a timer into a combo attack I have in my game, I want it to give you a certain amount of time to hit the enemy 4 times or it resets the value, snd I got it working where when I press the attack button the ComboTimer counts down, but currently it doesnt work like a clock, if decreased a little bit each time I press the key, but I want it to fully activate the timer with just the first click…

[shell sorrel]

transform.position = new Vector3(Mathf.Clamp(pos.x, xMin, xMax), pos.y, Mathf.Clamp(pos.z, zMin, zMax));

way simpler

[thorn kiln]

Possibly, but I haven't learnt about clamp, so you know

[shell sorrel]

the min and max values you would jsut get from the bounds of the renderer

like everything else in Mathf its a pretty simple basic math function

[native seal]

clamp is more of a math concept not coding

[shell sorrel]

its like if you combined a min and a max or if you just did conditinals for the lower and upper range

[shell sorrel]

when the button is activated you set a bool, while that bool is true, you add or remove Time.deltaTIme from a field and check if it has reached 0 or gotten to your duration

i mention add or subtract since some people like starting timers and 0 and counting up to a duration others like setting the timer to duration and working down to 0

I feel like im heading into manager hell. I previously have used ScriptableObjects for inventories since it allows me to plug the inventory into anything that needs it, for example the players inventory into the shop without it needing a reference to the whole player. However, SOs are awkward to save and serialize and are also a headache to create an runtime (for example a randomly spawned chest's inventory). Im instead going to make inventories just a POCO so they can easily be created at runtime, but now I have the issue of things needed references to them. would a InventoryManager singleton be a bad idea for this? It feels like everything needs a manager haha

[shell sorrel]

coupling happens at some point its your choice where that happens

but yeah i would just handle things like that that do not require unity features with just regular objects as well

[native seal]

so go down the route of an inventory manager? i guess another solution would be dependency injection but i dont really like that in unity tbh

[shell sorrel]

find with unity really most projects end up with some sort of manager singleton type stuff going on

since in unity you do not control the entry point like you would in a traditional application so its harder to pass dependencies down the stack

personally i would try and still get control over when its created and not just let the singleton pattern create it. Perhaps have 1 object that contains constructs and holds reference to a bunch of stuff like this

but yeah i am not really a fan of dependency injection frameworks either, rather just pass things around myself or provide a other way

[native seal]

could you elaborate on this? like currently for a lot of my systems, i have the object itself hold a prefab (if its a gameobject) or something similar, and have the singleton create something with it. is there a better way to do this?

for example, with my UI, the object holds a prefab of the window and the UI manager spawns the window on a canvas that all other UI goes on

[shell sorrel]

i thought you were purely talking about the data representation of inventory

[native seal]

well my point is that I would structure it in a similar way

object holds data about what kind of inventory, etc. calls Singleton.Create(data) which returns the instance it created

then the singleton can manage interactions between inventories
