[hollow field]

this is my log

(i edited the Debug.Log but forgot to save but it's the same thing)

[wintry quarry]

sounds like you've got two copies of the same script in the scene probably?

[rich adder]

put this
Debug.Log($" {name} [SPACE] pressed during game!", this);

click both logs and see if they take you to 1 object / script

[hollow field]

Dont code at 2am kids

I literally moved the script from an empty game object to different object but didnt delete the empty one

[rich adder]

tired **

[hollow field]

thanks @rich adder and @wintry quarry

im gonna head to bed before i break anything else ❤️

(and in code general)

[wise cairn]

making a basic jump script, how do i make it only work when touching the ground? here's my code

public Rigidbody2D rb;

private void Start()
{
    jumpAction = InputSystem.actions.FindAction("Jump");
}

private void Update()
{
    if (jumpAction.WasPressedThisFrame()) { rb.linearVelocityY = jumpPower; }
}

[cosmic dagger]

For starters, check that you're on the ground before allowing them to jump . . .

[rich ice]

use a raycast and check if it hits the ground

[wise cairn]

yeah that's what i meant how do i do that

[cosmic dagger]

You can find a solution on YouTube or Google by searching: ground check Unity . . .

[wise cairn]

ok thanks

[cosmic dagger]

There are tons of resources for that. Just search using the same question you asked us . . .

[radiant ferry]

Does anybody know any good ways to check when there are no active instances of a prefab in a scene? I'm making an asteroids clone to learn the ropes of Unity and I'm trying to detect when all the asteroids are destroyed so I can instantiate another round.

[ivory bobcat]

You could probably use object pooling with the asteroids and be able to tell how many asteroids you've got with it's collection/array implementation. I wouldn't recommend searching the hierarchy for objects unless you really have no other choice. If they share a single parent, you could probably use this to get the number of children https://docs.unity3d.com/ScriptReference/Transform-childCount.html

[radiant ferry]

Huh, I didn't think about that. I'll try that out thanks 👍

[eternal needle]

you don't need to check the transform child count tbh. if you go the object pool route, unitys object pool has properties you can use to get the number of objects active/inactive or both https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Pool.ObjectPool_1.html
Or if you dont go the pooling route, you need to store these objects in a list. Instantiate returns the spawned object. either remove it from the list when the objects are destroyed or just check if the list elements are null every so often.

getting the child count forces you to have these asteroids as children of a specific object which is a bit fragile and not needed

[radiant ferry]

Alright thanks, I'll try that too

[jade cosmos]

hey guys, so basically I am trying to see if a player has pressed a button while inside of a trigger using the if (Input.GetButtonDown) function but whenever I run it it errors with this error ArgumentException: Input Button Interact is not setup. To change the input settings use: Edit -> Project Settings... -> Input Manager UnityEngine.Internal.InputUnsafeUtility.GetButtonDown (System.String buttonName) (at <44a762dafa6b4e0ca8423d645d61ba11>:0) UnityEngine.Input.GetButtonDown (System.String buttonName) (at <44a762dafa6b4e0ca8423d645d61ba11>:0)

but how can this be whenever it is

[keen dew]

It says Input Manager, not Input System Package

[jade cosmos]

ohhhh

yea im illiterate

[north kiln]

the Input class is not the new input system

[jade cosmos]

it isnt? ummm stupid question but how would I change that

[north kiln]

The input system docs are pinned to #🖱️┃input-system

[jade cosmos]

so its not the updated system?

because I am using all the correct packages

sorry for ping forgot to turn it off

[north kiln]

It's a completely different API you have to use, you write completely different code

[jade cosmos]

because I have to use a controller?

like a player movement controller

uhh input controller

idk what its called

[rich ice]

the new input system is just a completely separate thing from the old input system. the input methods are still the same they're just handled and coded differently

i'd reccomend looking at docs or finding a tutorial online if you don't understand how it works.

[jade cosmos]

and lemme guess the new one is better?

[rich ice]

i personally think so, I don't know the specifics of it. but if you plan to add controller support then it definitely makes the process a lot easier.

[umbral bough]

Hi, is there a way to log an exception with the clickable stack trace and a custom message?
I tried this:

Debug.LogException(new(
    $"(Audio Manager) Failed to get or create source for '{audioItem.Name}'", e));

However, that logs the inner exception first, and the exception message later.
That's quite annoying and makes no sense.
Is it possible to somehow work around this?
Please @ me and thanks in advance!

[lament drum]

thank you so much!!!!!!😭

it works let's gooooooooooo

dosn't load the scene though 😂 I'm going to work on that now

[twin pivot]

Did you save the scene as Quarry in build settings?

[lament drum]

yes

[lament drum]

it's that right?

found the problem it's on me i forgot to put the working code in unity my bad

it was set on no function😅

[umbral bough]

[earnest wind]

Is this how u would make a SceneLoad without having the script on any gameObject?

[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.SubsystemRegistration)]
    static void InitOnLoad()
    {
        SceneManager.sceneLoaded += OnSceneLoaded;
    }

    private static void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
        TexturesLoaded.Clear();
        Debug.Log("TexturesLoaded cleared on scene: " + scene.name);
    }

im guessing i can just have it like this too?

[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    static void InitOnLoad()
    {
        TexturesLoaded.Clear();
    }

actually im just going to make a gameobject and just have it a reference since that would be easier for my life

[lament drum]

hy guys could somebody pls tell me how to show a menu in a game by pressing a button.
As of right now I have a little game project that works and the menu pannel that lunch at the start of the game from wich I can lunch it or exit from it.
How can I go to that pannel by pressing "M", while being in the game, I only understood that it's by the event system but I don't know how to do it.
Pls help

Here's my code for now :

function Update()
{
if (Input.GetKeyDown("m"))
{
SceneManager.LoadScene("MainMenu");
}
}

here's my error warning

Hey all,

Could anyone help me out with a little Logic & Maths please, my head is spinning a little. 😕

Basically trying to generate a black and white image (using red atm cause of another issue) at runtime with a couple of 'bands' of white on black based on input values between 0 and 90 for use as a mask elsewhere.

https://hastebin.com/share/jagopilofo.java

This is my current code. I'm certain there's a maths error in the ConvertLatitudeRange as my results don't seem to make sense (ie, I believe minMaxLatitude.y should be 614.4f.)

(Current Vector2 input is 30,60)
width is 1 (doesn't need to be bigger than that)
height is 1024
equator is height/2 (=512)

Couple of images for reference

1, input settings (Ignore Terrain layers section in Inspector, all that is disabled for now
2, current results
3, Highly detailed engineering schematic of what I'm trying to achieve.

[scarlet skiff]

colliders are starting to piss me off.

i use a grid collider on my grid map, i get stuck in nothing, same for enemies, cuz its "uneven" fir some stupid reason.

i use a composite collider, some raycast fail because they are cast inside the ground, bu dont detect it cuz composite collider is like not filled, additionally, it doesnt work well with astar pathfinding graphs.

wth am i supposed to do?

[sharp bloom]

What is a "grid collider"?

You mean a tilemap collider?

Make sure your physics shapes are right

[oblique chasm]

Best practices for modular architecture question
I have a ball and a zone. I would like the ball to destroy once it touches the zone.
My "Death" code goes on the ball. The zone however, should hold what it does independently of that right?
Should the zone, once collided with, tell the ball to run the Death code? This way if I have another zone that, lets say increases the amount of points you get or something, I could have the zone do both by having them be separate scriptable objects attached to the zone.
Otherwise, if I have the zone just say "hey, you hit me, I have x tags) and the ball read those tags then fire off the appropriate methods, the ball would end up containing a ton of code for each possible interaction with a zone. Even if the method doesn't affect the ball (Similar to the points example.)
Am I thinking correctly about this? I'm a bit mixed up cause I'm under the impression that the zone shouldn't talk to the ball, but this might be from previously working in godot where you "call up, signal down", or is this the same thing?

[wintry quarry]

Yes I think it makes sense for the death zone to tell the ball to die

[sharp bloom]

Maybe the zone could have an interface with some method like Interract() that does some different logic depending on what type of zone is it.

That way the ball script doesnt care about what type of zone it is, it just automatically calls Interract() if it enters any kind of zone

[lament drum]

hi so I've got this code to be able to go back to my menu if the character is inside the trigger zone, however for some reason when I press "m", it doesn't do anything and I am stuck in the current scene, how can I change scene by pressing "m", what is wrong in my code?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class MoveScene_OnKeyPress : MonoBehaviour
{
    [SerializeField] private string MainMenu;
    [SerializeField] private GameObject uiElement; 
 
    private void OntriggerStay(Collider other)
    {
        if(other.CompareTag("Player"))
        {
            uiElement.SetActive(true);

            if(Input.GetKeyDown(KeyCode.M))
            {
                SceneManager.LoadScene(MainMenu);
            }
        }
    }

    private void OnTriggerExit(Collider other)
    {
        if(other.CompareTag("Player"))
        {
            uiElement.SetActive(false);
        }
    }
}

[oblique chasm]

@sharp bloom If I have 5 types of zones though, wouldn't the ball need code for what each zone types does?

[slender nymph]

two things:

1. make sure the code is running (hint: it isn't)
2. GetKeyDown is only true for the first frame that the key is pressed which is not necessarily going to be a physics update frame. so you need to rework your logic a bit so you are checking for input in Update instead

[lament drum]

wait hold on I thought the code would be running if I put it in an object in Unity could you explain that to me pls?

[slender nymph]

what calls OntriggerStay

[lament drum]

my collider object

i didn't put it's name sorryyyy

[slender nymph]

how, it's a private method and isn't a unity message

[lament drum]

so if i put my collider object name it should work?

[slender nymph]

no

nothing is calling OntriggerStay

[lament drum]

oh

[rich adder]

https://docs.unity3d.com/ScriptReference/Collider.OnTriggerStay.html

C# is case-sensitive

[lament drum]

mm so I corrected and put the Trigger instead of trigger

but still same problem

[rich adder]

yea maybe thats a bit much

[rich adder]

is the UI appearing though ?

which part isn't working

[lament drum]

so when I load the game and I go to my trigger it doesn't show the text to change scene

and even if i press m it still doesn't change scene

[rich adder]

forget the keypress, is the UI appearing

[slender nymph]

have you fixed the logic issue i pointed out

[lament drum]

no

[lament drum]

no cause I didn't quite get it

[rich adder]

do you have at least 1 rigidbody or your tag is not set

[slender nymph]

ah yes, let's ignore advice about fixing an issue instead of asking clarifying questions. good choice 👍

[lament drum]

it's in rigid body but it's not set

[lament drum]

just didn't understand it that's why i asked about the first part before going to the second

[rich adder]

clarify what you mean "it's in rigid body but it's not set"

[lament drum]

my trigger has box collider but uiElement is not checked here's screen shot

or was it not the question?

[rich adder]

show Player that walks in this trigger has
a Rigidbody/CharacterController & tag set as "Player"

[sharp bloom]

I don't think so

I imagine something like this

[rich adder]

1. how do you know you're in the trigger at all ? you can't see the collider when testing
2. are you moving the rigidbody with AddForce/Velocity in code ?
3. is that box collider actually set to IsTrigger ?

[polar acorn]

Unfold the collider component and show what you have set for it

[lament drum]

I walk inside the trigger in the scene
for the rigid body (character right?) it's from an asset i don't know how it moves

and yes it's set to is triiger

I juste changed the name of my character to Player and the text appears in the game test by unity but when I build it it doesnt show

[rich adder]

what do you mean? the name should have no affect on this according to the code you wrote..

[oblique chasm]

maybe I'm having a hell of a time wrapping my head around this.
Lets say I have 2 zones, a destroy zone and a level up zone. If the ball hits the destroy zone it destroys itself, if it hits the level up zone it's "XP" variable goes up by 1.
In this case, the ball would have the "dostuff" method, but thats only one method. How is it supposed to handle multiple possibilities outside of doing somthing like tagging the zones?

[lament drum]

when i say to unity build and run it like that

[rich adder]

whatever you did it was def not changing the name, maybe something else save and it started working again.. either that or youhave poorly anchored UI so you can't tell as well when it appears somewhere else..

no where in the code you sent there is anything about gameobject name checks

[lament drum]

most likely, but i don't know anymore cause it works in unity but not when I say build and render

[rich adder]

that could just be poorly anchored text getting out of screen in bigger resolution

why not center the text? just for testing because on the edge is difficult

or better yet make something really obvious happen for testing..

[lament drum]

I will try that

good idea

[lament drum]

good news it shows when i go in the zone but it still dosn't change scene when i press "m"

[sharp bloom]

No the DoStuff() would be in the zones, not the ball. That way the ball can have no logic on its own.

And you can create as many new zones as you like, as long as they inherit from the zone interface.

I think it would be bad practice to code each individual interaction inside the ball.

Maybe someone can chime in on this as well, I'm not too good of explaining this.

https://youtu.be/2LA3BLqOw9g?si=wL8F6K4U0acOqu1T Nice quick video on interfaces

[rich adder]

okay the first part is solved. now instead of checking keys inside the TriggerStay loop, thats a physics loop, its difficult to catch a 1 frame event at exact time

You have to use update to capture inputs

so you either make a bool that you are insideTrigger with OnTriggerEnter/Exit then use that in update with keypress like if(insideTrigger && Input.GetKeyDown(KeyCode.M)
or
you can make a bool for KeyDownPressed, capture it in update then use it in the trigger.
sceneSwitchPressed = Input.GetKeyDown(KeyCode.M)
former is the cleaner option IMO

[sharp bloom]

At 1:45 mark, this is the exact scenario of having all the different interactions on the ball script, it becomes spaghetti

[lament drum]

so let's say I do

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class MoveScene_OnKeyPress : MonoBehaviour
{
void Update() {"rest of code"}
}

[rich adder]

read the message under that, should give you a bit more detail

[lament drum]

I like the second one better

[rich adder]

sure, it will work but probably wont be as good as option 1 tbh

but try it and see I guess

[lament drum]

I will go to option 1 cause if you think it's better I will try it first

and if it work i will try option 2 later

[rich adder]

yeah its pretty easy to do , basically same way you set bool for UI being activated / not but in a variable you can use in Update w keypress

[rich adder]

just being pedantic, classes don't inherit interfaces they implement them
big difference in how inheritance work but its strength / benefit because of it

classes can't inherit multiple classes , but classes can implement multiple interfaces (their major strength)

[sharp bloom]

Ye good point

I started coding in Python which actually support multiple inheritance, kind of cursed to think about when I've only used C# for the longest time now

[rich adder]

Python is weird

[sharp bloom]

I can't use it anymore lol, just too much weirdness

[lament drum]

ok so I got this for now and unity tells me :

• it wants a ";" in the world "other" so it would look like the "o;ther"
• and I can't use "="

? sorry for your patience but could you still help me with it pls?

[slender nymph]

there are beginner c# courses pinned in this channel. you need to start with those.

[rich adder]

what are you even writing..

[lament drum]

i'm lost

[rich adder]

yes you lack the basic c# probably something you want to be doing before anything

[sharp bloom]

I think you gotta learn more C# syntax

[lament drum]

Yeah but I need to present it to my boss on monday and I just started learning code

[rich adder]

IDE not even configured but thats the last of your problems right now, you wrote some nonsense syntax lol

insideTrigger is a variable that doesnt currently exist... the IDE / compiler would tell you but your syntax is completely fucked..

[lament drum]

oh

[sharp bloom]

So yeah line 13 is nonsense, you're trying to assign the value true to a function, I don't even know what it's supposed to be doing

[rich adder]

why did your boss assign a task you have no idea about ?

[sharp bloom]

You use it like

private void OnTriggerEnter(Collider other)
{
  //do stuff
}

[rich adder]

it would be one thing if it was slightly wrong but this is like beyond that lol

[sharp bloom]

Oh you have the other event functions set-up correctly 🤷

[lament drum]

so basically I did a 3D modelling of a quarry and she was like hey it would be good if we could walk inside it and here I am

[sharp bloom]

Maybe use a pre-built character controller?

There are free ones

[rich adder]

thats probably what they did, but now are in the classic "what did I get myself into, this is harder than I thought " when you have to meld different systems together

[polar acorn]

The fact that this code isn't underlined in red means your !ide isn't configured which would likely have told you this line makes no sense before you finished writing it

Hello, i took a webGl build of my game, when i click on the game window in browser it highlights the game window, turns to blue, and disables controls. It goes back to normal when i double click. How can i fix this?

[rich adder]

probably a better question for #🌐┃web

also would test different browser and see if its isolated issue

[cinder spruce]

all webGL questions should be asked at #🌐┃web ?

[rich adder]

tahts why I linked it

this felt to me like a code related issue but okay, thanks

[rich adder]

if you think its somehow code related, you should probably show any relevant code

[lament drum]

that's w
hat i did

[cinder spruce]

No, i haven't wrote a code to create this issue but i meant the solution of issue could be the adding a right code. Like cursor focus options. Anyway, i'll try this on another browser first

[ruby python]

Anyone.....please? 😕 Just need to be pointed in the right direction. lol.

[void dawn]

So I'm working on this single player fps game and Im having a lot of issues making enemies for it, to start many enemies seem to not have a concept of front they just move around and shoot in whatever direction they want to , and that only happens when the enemy AI work , even with nav mesh and everything some enemies won't even move or detect the player, some won't even play the animations correctly

Now that I think about it I think i haven't made a enemy that works as intended , can anyone tell me how do get out of this hole ?

[fallow wind]

how to code

[sharp bloom]

It looks like a bit complicated for a beginner problem, maybe ask in #archived-code-general ?

[ruby python]

I'm actually making progress, just trying to figure out the maths to correct the second 'bar' (Right Side) at the moment (and then need to figure out why the texture isn't displaying red&white like it supposed to. lol.

https://hastebin.com/share/yaruqakudu.java

Texture assigned in inspector via code.

[pallid nymph]

It's not red and white because of the green color selected in the material... it's a multiplier, so red *green = black, white * green = green

I don't see width, height and equator in code and how are they set and whatnot... code otherwise seems fine 🤔

I'd probably just do it all in a shader, but hey

[ruby python]

Ah okay, gotcha. Yeah that makes sense. not a big deal though really cause this isn't getting applied to anything, just doing that for testing to make sure I have my values correct. the right side 'bar' is beginning to annoy me. lol. And I need to do it in code to drive an asset based on values coming from an xml file.

[pallid nymph]

Feels likq equator is not the correct value, but I don't know

oh, it's visible in the logs...

[ruby python]

Yeah it is. textureheight/2

[pallid nymph]

oh, stupid me...

of course that's wrong... it only works if the middle of your min-max is the middle of the side

[ruby python]

This is an illustrated example of what I need to fix.

[pallid nymph]

you need to check if it's between height - max and height - min

in the else if

what you made is "repeat after mid point", what you need is "reflect after mid point" if that makes sense

[ruby python]

Yeah, it's the translating from 90-0-90 (top, middle, bottom) to 0-1024 (top - bottom) that's getting me. lol.

[scarlet skiff]

Yes, tile map collider. Also wdym make sure my physics shapes are right? I use click "used by composite" on the tile map collider. That's what I mean by using it, and those were the cons of using it, likewise if I just don't use it, I get the other cons

[willow iron]

        float Angle = Mathf.Atan2(look.y, look.x) * Mathf.Rad2Deg;
        float fAngle = Mathf.Clamp(Angle, -30, 30);
        transform.Rotate(0,0,fAngle);```
my value is not being clamped?

its currently at -84 as we speak

[modest dust]

And what are you trying to do?

[willow iron]

get the gameobject the script is attached to to face a transform (this transform being the player variable). If the player transform is more than 30 degrees away from the front of the gameobject, it will be considered out of sight and the gameobject will no longer rotate towards the player. This is a 2d game, and the code works perfectly except for the fact that fAngle seems to not be getting clamped at all.

[modest dust]

transform.Rotate changes the rotation of the transform by the given amount, that is, for example similar as if you did current_rotation = current_rotation + your_angle

You're just clamping your_angle but the rotation still occurs, there is no code preventing that

If executed several more times it eventually face the player

[jolly stag]

Heya I was wondering if I could get some help, I'm trying to get something to spawn either on the left side or right side of the screen. The code seems to work when forced to pick a side by changing the range random can do to either 1 or 0 but when given the option it only picks left.

    {
        if (Input.GetKeyDown(KeyCode.J))
        {
            Instantiate(powerUpMGPrefab, RandomPowerUpSpawn(), powerUpMGPrefab.transform.rotation);
        }
    }

    private Vector3 RandomPowerUpSpawn()
    {
        float limits = 4.24f;
        int leftRight = Random.Range(0, 1);
        if (leftRight == 0) 
        {
            Vector3 spawnPos = new Vector3(-limits, 1, 1); //Spawn Left
            return spawnPos;
        }
        else { 
            Vector3 spawnPos = new Vector3(limits, 1, 1); //Spawn Right
            return spawnPos;
        }
    }```

[polar acorn]

Random.Range with integers is max exclusive. So Random.Range(0,1) can only roll 0

[jolly stag]

I'm unsure what max exclusive means, so would I have to do Random.Range(0,2) or just get rid of the 0 entirely?

Well from playing about rasing the number to 2 worked. Thank you for your help :)

[rich adder]

when its max exclusive , you always want your wanted value max+1,
so yeah if you wanted range 0-2 you would put 0,3 and so on..this only for integer version
float version is max inclusive meaning the number you put doesn't need +1 cause its included in the range 0f,2f gives any decimal between0f-2f

[jolly stag]

Ah alright that makes sense, thank you so much for explaining it in detail :)

[hidden fossil]

guys where is the use composite checkbox?

used by composite

[rich adder]

"Composite Operation"
also not a code question.

[hidden fossil]

do newer versions not have the checkbox and it just becomes composite operation

[rich adder]

yes it was changed in newer version

Is there a way to pull all the api documentation for just the packages you have installed? usually when I am coding I have the documentation in a folder somewhere, and I just search within files the method I need info about and I can just get that info inside my IDE. heck sometimes I don't even have to click on anything

Anyone have a good way they get all the stuff in the same place to reference?

Hello dear Uniticians,
Im using the code below, to draw a ray to where the player is looking, and to move an empty object (that is marked by the sphrere), however even in play mode the ray and the empty object is somewhere in the very wrong place, where the player is clearly not looking. Thank you in advance for any help.

using UnityEngine;

[ExecuteAlways]
public class RaycastVisualizer : MonoBehaviour
{
    public Camera playerCam;
    public Transform marker;

    void Update()
    {
        //nre check
        if (!playerCam || !marker) return;

        Ray ray = playerCam.ScreenPointToRay(new Vector3(0.5f, 0.5f));
        if (Physics.Raycast(ray, out RaycastHit hit))
        {
            marker.position = hit.point;
        }
    }

    void OnDrawGizmos()
    {
        //nre check
        if (!playerCam) return;

        Ray ray = playerCam.ScreenPointToRay(new Vector3(0.5f, 0.5f));
        Gizmos.color = Color.red;
        Gizmos.DrawRay(ray.origin, ray.direction * 100f);
    }
}

[rich adder]

have you tried doing Ray ray = new (playerCam.position, playerCam.forward); instead ?

[glad ibex]

That wouldve been too intelegent for me, ill try, thanks

[rich adder]

might be the same thing but worth a shot, can you show gizmo for the camera transform in local pivot mode ?

[glad ibex]

Yep works, thanks!

[hallow acorn]

can someone tell me why i get the error "The call is ambiguous between the following methods or properties" in visual studio on playerControls = new PlayerControls();, playerControls.Enable(); and playerControls.Disable();? heres the code: ```cs
public class playerController : MonoBehaviour
{
private PlayerControls playerControls;

[Header("Values")]
[SerializeField][Range(.01f, 10)] private float speed;

private void Awake()
{
    playerControls = new PlayerControls();
}

private void OnEnable()
{
    playerControls.Enable();
}

private void OnDisable()
{
    playerControls.Disable();
}

private void Update()
{
    Move();
}

}

ignore Move(); in Update i deleted it to shorten the code a bit

[glad ibex]

Is PlayerControlls also a mono behaviour by any chance?

[hallow acorn]

yes its the generated c# class of my inputActions

[glad ibex]

Hey so take my word with a big big big grain of salt, but i think that your not supposed to use construct monobehaviours yourself

Better use gameObject.AddComponent or add it initially if u dont need it on awake and need it allways

[hallow acorn]

it has always worked tho i used it almost since it came out

[rich adder]

if it was generated class from input asset its not a MB

[glad ibex]

Shit, sorry, can you show the error exactly then (screenshot) as I didnt fully understand from your wording

[hallow acorn]

wait i think ill try to regenerate the class as i now get errors in it too after opening

ah yes

good old unity bug

didnt know what happened but it worked after regenerating it

[glad ibex]

Mice!

thanks for the help even tho it fixed itself haha

Hello! I need help figuring out a collision error with my player to the wall.

using UnityEngine;

public class playerMovement : MonoBehaviour
{
[SerializeField] Rigidbody2D rigidBody;
public float Playerspeed;
float moveSpeed;
float moveSpeed2;

// Start is called once before the first execution of Update after the MonoBehaviour is created
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    moveSpeed = Input.GetAxis("Horizontal") * Playerspeed;
    moveSpeed2 = Input.GetAxis("Vertical") * Playerspeed;

    transform.position += Vector3.right * moveSpeed * Time.deltaTime;
    transform.position += Vector3.up * moveSpeed2 * Time.deltaTime;
}

}

[rich adder]

all sorts of wrong here..

[wicked fiber]

oh...

[rich adder]

moving transform will teleport through walls , you need to use the rigidbody component methods

[wicked fiber]

what would be that scripts name?

sorry i started 3 day ago

[rich adder]

Rigidbody2D component you have to access the values with the . if you just started recently I would suggest you go through the unity !learn 👇 starters/junior courses they guide you through learning rigidbody movement and more.

ok, so theoretically, it would be something like "RigidBody2D.movePosition" right?

[rich adder]

it has that but thats for kinematics. its usually https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForce.html
or https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Rigidbody2D-linearVelocity.html

[wicked fiber]

ok thanks!

[lilac fractal]

In my game, waves of enemies can spawn. There can be different enemy types within each wave.
If I wanted control over spawn patterns (for instance, one large enemy in the middle with 3 small enemies in front), how do folks go about modeling this? I could quite literally have several code files that denote enemy type and location to spawn them in, but I'm wondering if there's a prettier way

It almost feels like I could be doing a prefab and building this in the editor drag/drop

[shell sorrel]

would create some sort of data structure that defines that

store it in scriptable objects or something like json that your system ingests

[modern aurora]

Could use some help here

using UnityEngine;

public class TileScript : MonoBehaviour
{

    TileController tileController;
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    private void Start()
    {
        tileController = GameObject.FindFirstObjectByType<TileController>();
    }

    private void OnTriggerExit(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            print("it works!");
            tileController.SpawnTile();
        }

    }

}

trying to spawn a tile when the player leaves a box collider trigger area. neither printing nor spawning occurs. i have a feeling i just didnt implement my trigger correctly but im not sure. player has player tag and has a rigidbody, the collider in the tile is marked as a trigger, so idk

The SpawnTile function is a public function in the tilecontroller if you need to see that as well.

that embed didnt work at all lmao

Skybox

[wise cairn]

the black and red thing right?

[eager spindle]

Yep, show us the Transform

What's the position of the sprite?

[twin pivot]

Change the color of ur skybox if u dont like the blue color

[eager spindle]

The sprite isn't appearing in game

[wise cairn]

and also the ground

[eager spindle]

Hmm what's the position of the camera then?

[twin pivot]

Is the sprite supposed to be a ui thing or a world thing

[wise cairn]

i have it set to go towards the player

[eager spindle]

The camera needs to be "behind" the sprite(z position is -10) in order for the camera to see the sprite

HI

how to declare array of arrays in correct way?

i tried Vector3[][] myArrays={new Vecto3[],new Vector3}

but it didn't work

[teal viper]

Vector3[][] a = new Vector3[][size];
//Then init each sub array separately(for example in a loop)
a[0] = new Vector3[subSize];

[candid garden]

I've got this script for managing stats on my characters but I can't get the _basevalue and _modifiedvalue to show in the inspector, any idea's why not?
The BaseValue and ModifiedValue show up but if I set the BaseValue in the inspector the game just ignores it and when I try to fetch the data it resets to 0

[eternal needle]

do u declare an instance of this class anywhere? this is just the class

[candid garden]

This is where I create the attributes
[System.Serializable] public class Attribute { [System.NonSerialized] public RemnantEquipmentAndStats parent; public RemnantStats statType; public ModifierInterface modifierValue; public void SetParent(RemnantEquipmentAndStats parent) { this.parent = parent; modifierValue = new ModifierInterface(AttributeModified); } public void AttributeModified() { parent.AttributeModified(this); } }

[eternal needle]

this is still just a class. you need to declare this on some unityobject for it to show up anywhere

[candid garden]

The attributes are in an array in a data class for a list of characters kept in a Scriptable object

it shows up like this

I have a list of modifiers for adding modifieres to the stats non destructively, but I've been getting a null error for this list, could that be the issue?
public List<IModifier> modifiers = new List<IModifier>();
this is where it returns null
public void UpdateModifiedValue() { var valueToAdd = 0; if (modifiers == null) { Debug.LogError("Attempted to update null modifier"); return; } if (modifiers.Count > 0) { for (int i = 0; i < modifiers.Count; i++) { modifiers[i].AddValue(ref valueToAdd); } } _modifiedValue = _baseValue + valueToAdd; ValueModified?.Invoke(); }

[ruby python]

Okay, very confused. Not a coding question but tbh, I can't really see anywhere to post.

But, CharacterController step offset is weird and I really don't get it.

Calculator result is Height + Radius * 2 of the Character Controller height & radius, as the error says. But i'm still getting the error.

It's truly baffling how this works tbh. The errors only disappear when I put the step height to around 0.2 😕

[orchid swallow]

Attack 2 is not working after Que attack, what is the cause

[orchid swallow]

public void OnAttackAnimationEnd()
{
Debug.Log ("OnAttackAnimationEnd called");
if (queuedNextAttack)
{
queuedNextAttack = false;
comboStep++;
StartAttack();
}
else
{
isAttacking = false;
comboStep = 0;
animator.Play("xVelocity.Idle", 0); // Optional: return to idle state

#💻┃unity-talk but PEMDAS rules apply. 0.19 + (0.02 * 2) = 0.23

[ruby python]

Ah dammit. Yeah, the error isn't overly clear on that point. lol. Thank you.

LMAO. Even doing that, calculator result = 0.23998908
enter 0.23, still get the error.

Anything above 0.2 I get the error. (even 0.201), sod it, 0.2 will do for now.

wtf? Now it's changed its mind and anything above 0.195 throws the error.

[pallid nymph]

Is there any scaling going on?

[ruby python]

Okay, this is massively weird.

Because the 'working' step offset value was so close to the 'height' I tried this.

and yeah, weird but if the step offset is higher than the height, it throws the error. lol.

Okay, I'll go sit in the corner. my main root object isn't scaled, but the actual character model is, so I'm guessing the value of 0.23 should actually be 0.023

I forgot I'd done that. lol.

[lost maple]

это ты чо такое наделал то?

[grand badger]

Anyone needs help? :p so many unanswered questions above

[eternal needle]

Those seem to be the correct fields showing up. Your property BaseValue isnt what youre seeing here because properties arent serialized. Same with modified value.
I dont really know what your IModifier is because you never showed it or a class that inherits it. I assume a unity object is inheriting it (like a monobehaviour). In that case, your null check isnt using unitys null check and you'd need to cast it to a unity object

[rich ice]

how do i subscribe a function to an event?

[grand badger]

assuming you mean on a button, myButton.onClick.AddListener(() => MyFunction(parameters));

or if it's a standard C# event, myEvent += () => MyFunction(parameters), or even just myEvent += MyFunction if the event parameters match the function's

[pallid nymph]

I sometimes come here when I'm bored too 😅 (bored = procrastinate-y)

[rich ice]

ah i see, thank you

[umbral bough]

Hi, I have this struct in Unity:
https://hastebin.com/share/gozotevuvu.csharp
I have to have the constructor with all the optional parameters but would also like to have default serialized values in the inspector.
Is that possible?
Thanks in advance and please @ me.

[rich ice]

same, gives me a good excuse to not work while simultaneously learning something new. or atleast feel like im doing something productive lol

[eternal needle]

Was there some AI shenanigans when making this code?
This isnt a struct and there's pretty weird logic in that. Like why are all those vectors nullable if youre just going to assign it a specific value if null. Just skip the nullable and assign the default value in the parameters

If you want it to have specific values in inspector too by default, you do the same thing you would do in component. Assign the value on the same line where you declare the variable

[pallid nymph]

It's more like "you don't have to pass them", no? You can't have a default for a struct. 🤔

[umbral bough]

Nope, written it myself.
Not a struct?
As for vectors being nullable, I have a simple explanation.
I want to allow users to still input Vector2.zero(aka default) while making sure that if not assigned by the user(null), I assign the default value.
And lastly, why don't I just assign a value in params? Take a look at the picture below.

ah, my bad, I said struct instead of class, p fried atm

[pallid nymph]

where does this "serialized bla bla ignored during serialization" come from? normally doing public Vector2 VolumeRange = Vector2.one; works fine

do you have a list of those classes by any chance?

[umbral bough]

nope, let me just define it as a field in a class
[SerializeField] private AudioItemSettings set;

[eternal needle]

You dont need the nullable at all here

[umbral bough]

sure, I am open to suggestions

[pallid nymph]

This is what I get without the attributes, so I blame them 🤷‍♂️

[umbral bough]

odd, let me try it on my end rq

[eternal needle]

#💻┃code-beginner message
The suggestion was what Pulni was also writing. My mistake on the parameter part

[umbral bough]

That sadly didn't work.
I removed literally every single attribute in that script, readded the script and still the same :/

[pallid nymph]

What version of Unity? 🤔

Oh, also it only works for new instances maybe

[umbral bough]

and also, wdym by works for new instances?

[rich ice]

rip
automod doesn't like single word messages. i think it would've worked if you said "unity 6"

or just extended the message some other way

[umbral bough]

ye, anyways, if you got ideas as to why I can't have default values on these fields just @ me

it's 99% not the attribtues as I removed them, and rider also suggests that there's a deeper issue

[rich ice]

according to this thread, it's a bug.

[umbral bough]

I see, how come it worked for Pulni?
Is it a Unity 6 bug or sm?

[rich ice]

definitely a weird bug though. (assuming the thread is correct and i didn't misunderstand anything)
i might need to mess around with this myself and see if i can find anything

[rich ice]

according to the thread, it's been an issue with unity for a while, they just never got around to fixing it.

although, let me try it on my end real quick. i'll see if i can come up with anything new

[umbral bough]

This seems like a major issue, odd that it hasn't been taken a look at for so long.

[pallid nymph]

That's why I asked if it's in a List. They tend to not work in lists. I tried to do a workaround before, buut I think it was getting way too hacky or something and I noped out.

[umbral bough]

nope, not a list, it's always a field, or a field of a field

[pallid nymph]

If you have a serialized object and you add an initializer value, the objects that are already serialized won't get the new value. Won't even work if you add a new field that's initialized.
Or at least I think it might be the case. I can test it later.
My point was to do it without the attributes and make a new instance of the thing that contains the field or at least reset it. See if that makes it work.

[tepid urchin]

I'm moving items from inventory to chest...
When I have a stack of existing items to fill, this means changing the amount number in chest and deleting the item from inventory.

Items are just game objects with a script and child object that has canvas renderer + image (which has child for amount text).

In method for filling partial item stacks, I do "Destroy(sourceItemUI.gameObject);", but nothing happens. The game object is not being deleted ever.
If I do DestroyImmediate, it will get removed as expected.

What is happening here? As I understand, DestroyImmediate should not be used if possible due to potential unexpected issues (that I didn't investigate too closely atm)

[umbral bough]

Just tried adding the component to a completely new object, if that's what you were saying, still the same sadly.

Ok wait, this might've just answered my question...
https://discussions.unity.com/t/unity-ignoring-class-member-initialization-value/893010/5

yeah that was it, excellet :/

guys i wanna add in day versions and night versions the day scripts (for example day1 script for the first day) and i will have like 50 days but the problem is that i cant put the scripts inside of these can someone help me?

[rich ice]

are the scripts attached to a GameObject?

[kindred iron]

no i dont wanna attach the scripts to a gameobject because like i said there will be 50 days and i will have to create 50 Gameobjects

and if i attach the scripts to the gameobjects it will be soo massy

i dont want that

[past yarrow]

Wait what ? Why do you need 50 scripts for 50 days ? 🤔 It should be only 1 script for all the days 🤔

[kindred iron]

i will make texts for each one

[past yarrow]

what texts ?

[kindred iron]

in this box will be wrote the texts of the each day like in day 1 there will be text options for day2 script the options will be different

[past yarrow]

Ok then you're approaching the problem the wrong way, the script that handles your day should only be 1 not 50. In that script you can add either an array of strings where you put your text, or if it's more complicated than that use Scriptable Objects, and each day you switch to the right one

[queen adder]

your script expect the script "Day Script" not day1 script, correct me if im wrong

[kindred iron]

yes but all scripts inherits from Day Script

[kindred iron]

hm makes sense but

how can i make options like for each options

[rich ice]

in order to assign a reference to a script in the inspector, it has to be attached to a GameObject

[past yarrow]

What do you mean by that ?

[kindred iron]

like i wanna code these SOs like if this gameobject got selected then this happens specific

[past yarrow]

Could you explain what kind of text are we talking about ? Is it just "Day 1", "Day 2" written on your HUD screen ? or some dialogue (with or without answers for the player to click) or quests ?

[kindred iron]

dialogue

there will be a lot of text in each day

[past yarrow]

Follow this : https://youtu.be/hG6EMeArp04

[kindred iron]

On Day1 there it will be like
string[] dialogue;
dialogue[0] = {
text = "hello world";
type = Types.NotQuestion
};

[kindred iron]

ok lemme watch

[past yarrow]

Yeah don't do that, it will be painful for you to do and to maintain

[kindred iron]

how should i do that then

like the video?

[past yarrow]

Watch the video

[past yarrow]

yes

[kindred iron]

ok

ty

[rich ice]

that's kind of similar to how i manage my dialogue in one of my projects. i have a dialogue class which i serialize in the inspector and then send over to a UI manager when it's triggered.

[past yarrow]

it must have been painful, isn't it 👀 ?

[rich ice]

at first it was, that was mostly just writing the script though. only problems i have with it now is that i forgot to add comments lol

[kindred iron]

the video u sent me dude uses a package and its very very complicated

and i wanna make my own dialogu system which is not messy and not hard to make

[past yarrow]

it takes a bit of time to get used to it and learn it but once you do you will understand why it's better to go that route than doing yours the way you wanted to do it 🙂

[kindred iron]

the way i wanna do it is bas i got it. Ima try to look up it on youtube. Because the thing that i wanna make is like dialogue system. If i still cant, ima write here and try to make another way

also not a code question

[pearl current]

Does anyone have any useful tips on how to deal with enemy cluttering? To give more context the tracking script is fairly simple:

private void MoveTowardsPlayer()
{
    transform.position = Vector2.MoveTowards(transform.position, player.transform.position, speed * Time.deltaTime);
    animator.SetBool("isAttacking", false);
}```

[frosty hound]

You'll need to look up the implementation of boids

Also known as flocking

[night mural]

depends what your goal is but simplest would be to have a variety of enemies in the encounter so that you don't have to deal with it 😉

[pearl current]

I'm in the process of building out the core gameplay aspect of my project rn. eventually i'm going to add new enemies with different behaviors but if i spawn 2 of the same enemies within the level i don't want them to clutter up

[night mural]

if you look at games like doom, the generic melee enemies are really slow so that they mostly don't end up clumping before they die

[night mural]

well now I don't know what you mean

2 enemies in the same level shouldn't clutter up? what does that mean?

oh you're just moving their posisions so they are literally inside each other

[pearl current]

yes

[night mural]

you could probably toss colliders on them

otherwise yeah, roll your own spacing system, but it depends on the kind of game whether that makes much sense

[pearl current]

they do have colliders

[night mural]

you need it for an RTS but in an FPS you are probably better off designing enemies that don't swarm the player so effectively

hmm well my recollection is that that should work but you might need to move them via their rigidbody instead

[hollow field]

is there a way to change a toggle button so the checkmark doesnt disappear when you click it?

[rich adder]

Probaby , but if you need to have custom behavior or images why not just build your own system with iPointer interface

Hey I'm trying to use the 2d multiplayer prefab but I cant figure out how to edit the scenes/make new ones, can someone help me?

[rich adder]

if you can't modify prefabs should you be doing anything multiplayer related

[queen adder]

Could anyone recommend a video or article explaining the weighted list class? (the simpler the better)

[grave frost]

is this in a build?

[naive pawn]

what weighted list class

[queen adder]

class WeightedList<T>

[grave frost]

I don't think that's a class provided by unity or c# by default

[queen adder]

oh is it not?

[grave frost]

In general: if I first launch the game,

[naive pawn]

it is not, no

[queen adder]

ouch, that was a perfect solution

[naive pawn]

you could make it yourself

but it doesn't really sound like it needs to be its own class

ah wait i misunderstood the "weights" aspect, i was thinking of priority

[queen adder]

I copied this off of google ai summary so i cant really tell where i got it from

and now i cant find anything on it

[naive pawn]

lol lesson learned real quick, eh

googling "weightedlist unity" gave me plenty of results though

[queen adder]

yeah just not a class

i think im fine then

thanks

Hello! I have a few questions regarding setting up Unity for coding.

I am using the version 6.1 right now.

• How do I set it up for Visual Studio Code as I don't see the package in Package Manager.
• Everytime I try to work with Input.GetAxis("Horizontal"); it gives me an error that, that way of doing things is old.

[slender nymph]

!IDE

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[slender nymph]

as for the error you are getting, it isn't saying that is old. it is saying that your project is currently set up to use the input system in the active input handling settings. it even tells you that setting is in the Player settings so you can go and change it if you intend to use the input manager

[hollow field]

I'm at my wits end with UI stuff. I have a game object with a box collider and several children. I have a script that has both OnMouseEnter and OnMouseDown but neither of them are activating

[queen adder]

Would you suggest 6.0 or 6.1?

[edgy tangle]

I could be wrong but I think those only run for the collider attached to the same gameobject. That’s at least how OnTriggerEnter, etc. work.

[slender nymph]

use whichever version the course you are learning from uses

[edgy tangle]

In other words those event functions will not run as a result of the mouse entering colliders in child gameobjects

[hollow field]

I have the Box Collider 2D and my script on the same game object

[slender nymph]

if you're using the Input System rather than the old input manager you'll need to switch to using the event system interfaces like IPointerEnterHandler because OnMouseXXX does not work with the input system

[queen adder]

Which course would you recommend?

How about layers? And is there anything that could be blocking the detection? Like a canvas that’s blocking your collider?

[edgy tangle]

Wait really? I didn’t know this

[slender nymph]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.14/manual/KnownLimitations.html

[edgy tangle]

Using the IPointer interfaces are better in most ways anyway. Just not automatic so it requires more setup

[hollow field]

everything here except camera and eventsystem is on the UI layer

[edgy tangle]

Per what Boxfriend shared, these functions apparently won’t work if you’re using the Input System rather than the legacy input manager. Are you using Input System?

[hollow field]

I dont know what Input System vs input manager means

[ripe lotus]

Hello, i'm using OnMouseEnter() to debug why onmousedown has issue. And as you can see the enemy is causing the OnMouseEnter keeps incresing and is incresing even more rapidly with the speed of the enemy ( there is no issue when the speed is 0 ) Do you know why ?

I know that some fix is to use raycast or idk but i rly want to udnerstand wtf is happing here

thx !

[grand snow]

Id replace this and use Pointer events with an event system instead

https://docs.unity3d.com/Packages/com.unity.ugui@2.0/api/UnityEngine.EventSystems.IPointerEnterHandler.html

Requires an event system to be in the scene AND the corresponding physics raycaster component too:
https://docs.unity3d.com/Packages/com.unity.ugui@2.0/api/UnityEngine.EventSystems.Physics2DRaycaster.html

This will then work using 2d colliders for example.

I use this a lot and im happy with how it works in 3d and 2d

[frail hawk]

do we have ui elements here

just asking

[naive pawn]

a channel in the server?

there are 2 channels with "ui" in the name

[frail hawk]

nono i am asking because rob mentioned IPointerEnterHandler

[slender nymph]

that can be used for world space objects

[frail hawk]

then this is new to me

[slender nymph]

did you not think it was odd that rob said they needed a physics raycaster component? that is obviously unrelated to UI, it's what makes it work for detecting colliders in the world

[frail hawk]

fair enough, did not see that part

[grand snow]

Yea its used with ugui but also works with 2d and 3d physics

ugui elements DO block the raycasts too which is usually a good thing too

as its all the same system, meaning no dumb work arounds checking "is cursor over ui element"

[lilac fractal]

What's the general vibe for those who want to use SOAP to reduce the dependencies of GameObjects to each other?

[grand snow]

Using events or interfaces or sub classes should solve this

[lilac fractal]

I'm struggling to do something like... I have a ProjectileController with a ProjectileHItboxBehavior on it, and an EnemyController with an EnemyMovementBehavior on it. Behaviors are children, controllers are the "root".

When a projectile collides with an enemy, it should raise an event that a collision occurred. Right now, this event exists on the EnemyController, so I have to have a behavior reference another controller, to invoke the event.

When the event is invoked on the EnemyController, and can then inform its behaviors (e.g. MovementBehavior, VisualBehavior, AudioBehavior) about the collision

This feels like a lot of knowledge sharing and boilerplate and I don't quite know a better way. It seems like it could "all be solved" if every involved party (ProjectileHitboxBehavior, EnemyMovementBehavior, EnemyVisualBehavior, etc..) could just reference the same event scriptable object.

[grand snow]

if you split things up too much you may be inventing the problem

[lilac fractal]

You think what I'm doing is somewhat overkill?

[grand snow]

maybe, if its not helping or providing benefit having things be separated soo much, why do it?

[lilac fractal]

I know it will

[grand snow]

A projectile probably will deal with collision so why does it need a seperate component to handle collision?

[lilac fractal]

The movement/physics in my game alone is quite a lot of code, I don't want to mix in audio, sprites, particles, etc..

Essentially what I'm trying to do is have a system of parent/children, where the parents orchestrate and the children get fed data

[grand snow]

Then its either manually made events, some event bus or explicit dependencies passed around

[lilac fractal]

That's why I think SOAP aligns with how I think

I can define an event as a first-class asset in my prefab to be invoked by others

[valid violet]

You can use public Action MyEvent; as field in any class and then asing it from any place

[eternal needle]

at first i was thinking you were talking about SOAP like the message protocol.
ive never seen a proper use for scriptable objects as events. it really doesnt provide you anything here other than just moving where the event happens from. You aren't reducing the dependencies, you're just hiding them

[lilac fractal]

Hah, no, I deal with wcf and SOAP enough at my job I have no intention of willingly touching it

Ultimately I just want to see if I can reduce my boilerplate and the fact that references to my root controllers need to be shared to trigger events

[eternal needle]

are your "controllers" the scriptable objects here? its really hard to follow logic or what is really the struggle here when we dont exactly see what the system is. If you want to separate things to this degree, yet have everything go through 1 controller, everything has to reference this controller or each other either way.

[lilac fractal]

And my children subscribe to the toot controller’s events

I’m not using scriptable objects yet, everything is a mono behavior

So I guess - assume for simplicity's sake that every gameobject look ssomething like -

FooController
  FooAudioBehavior
  FooVisualBehavior
  FooCollisionBehavior
  FooMovementBehavior

Everything here is a MB

[eternal needle]

then tbh i dont see what the problem is or how "it could all be solved if every involved party ... could just reference the same event scriptable object". Every object here can also just reference the FooController

[lilac fractal]

So if I want something like the ProjectileCollisionBehavior to be able to notify the EnemyController that it just hit, to say "hey mate you just got bumped, here's how hard"

e.g.

    public void OnCollide(ProjectileController projectile, GameObject target, Vector2 relativeVelocity)
    {
        if (target.TryGetComponent<EnemyController>(out var enemyController))
        {
            var direction = (projectile.transform.position - enemyController.transform.position).normalized;
            var velocity = relativeVelocity.magnitude;
            var pushForce = Mathf.Min(velocity * ForceMultiplier, MaxPushForce);

            enemyController.OnCollide.Invoke(direction * velocity * pushForce);
        }
    }

Now all of my behaviors in the EnemyController like audio, visual, movement, need to subscribe to the OnCollide event

The way I see it, it makes my behaviors dependent on their parent Controller, and it requires other components to resolve a reference to the Controller they want to notify

Maybe I'm overthinking it and that's just "okay"

Maybe I could define the OnCollide event at the root level of my Enemy prefab, and instead of resolving the controller, I can try to resolve ICollidable on the target of my collision

And then my enemy behaviors could subscribe to that, instead of it being on the controller.

[eternal needle]

they are dependent because they depend on it existing. Think about it like this, would EnemyVisualBehavior or EnemyMovementBehavior ever exist without a EnemyController? your game probably would feel wrong if an enemy made no noise, so to some degree you also rely on every character having some kind of AudioBehaviour.
for that method above, idk where you would really be putting this. It doesnt make sense that a projectile would be hitting a target and then have to call that method above. The projectile should know its direction already and should try getting the enemy controller from the beginning to notify it was hit through calling a method. You ideally wouldnt be invoking a characters OnCollide method yourself, the character should do this by themselves

the only other concern id have would be that you have a projectile specifically trying to target an EnemyController rather than some base Character which can apply to your player as well. Right now you would need separate code for the same projectile to hit a player

[eternal latch]

Hey! Genuine question: Do ya'll write most of your code without tutorials? It's been so tough writing code on my own even when it came to writing a CharacterController movement script...

I've been struggling lol

I might be in "Tutorial Hell" but I've tried creating the simplest games on my own and just couldn't

[ripe lotus]

hello following this issue i found that i can do a raycast of lenght 0 :
RaycastHit2D hit = Physics2D.Raycast(worldPos, Vector2.zero, Mathf.Infinity, tileLayer);

is it inconvenient in some cases ? it feels like a hack and i still don't know why i had my issue earlier

[modest dust]

I write my code with tutorials named "documentation" and "research".
The best way to tackle a problem is to break it down into separate steps and solve one at a time. If you're stuck on a single step instead of a whole complex problem then it's easier to search for a solution.

But of course, start with !learn if you haven't done so already

[polar acorn]

Just start being okay with being wrong. Come up with an idea and attempt it. It probably won't work. Then start trying to figure out how to make it work which will be easier because you have it at least somewhat formed. Repeat until the "won't work" step starts becoming rarer and rarer

[formal tide]

Do you guys recommend any unity c# book

[valid violet]

@formal tide I would recommend you this videos https://www.kodeco.com/3247-beginning-c instead a books

and for Unity there is a lot learning material on Unity3d site and Documentation

[formal tide]

Thanks

[formal tide]

Is this free. I guess i need to create account

[valid violet]

it was free

[formal tide]

Can i find every method in there

Every method that exists in unity

[twin pivot]

[eternal falcon]

:teacher: Unity Learn ↗

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

[formal tide]

I watched this

Until the end

[valid violet]

U can find every think you need there https://docs.unity3d.com/Manual/scripting-get-started.html

[twin pivot]

I doubt that

[formal tide]

Well i guess i need to do examples because i wanted to do my own code and i couldnt

I wanna make my camera follow my ingame character(cube)

I couldnt do it

[valid violet]

Just google there lot of such examples or use ChatGPT it can give you examples too

[formal tide]

Do u guys have any recommendation how can i writr my own code and learn it rather than followin tutorials and copyng pasting

[sour fulcrum]

dont use chatgpt, it's shit

[valid violet]

chatGPT give simple code but for something complex it is shit

What do you mean watch it again theres over 750 hours of content

[valid violet]

check this https://docs.unity3d.com/Manual/working-with-gameobjects.html if you need to work with gameObjects if you read step by step you will have all info you need

[formal tide]

Uhh i watched just one tutorial. He was making a game

First one

[twin pivot]

Rolling a ball isnt the only thing there is

[formal tide]

Yea that one

And car

[formal tide]

Yea i have this link on the side as well

The thing is im learning veery slow. Everyone said i can learn basics in 2 weeks. I spent 2 months for basics and not fimishrd

Finished

Is this normal

[valid violet]

You can spend years to start writing good code

[formal tide]

Yea

[valid violet]

and you can create somthing by following the tutorial and modify it in a months

[rich ice]

[formal tide]

Thanks

[twin pivot]

And also stop using ai for this

[formal tide]

Alright

[valid violet]

When I started I watched only video tutorials I was able to create feachures I need for my games by just googling and add feature by feature to my game. If you start developing you should also google Scriptable Objects it is not oblivious Unity3d feature but useful

[formal tide]

I tried to write wasd controls and space for jump code. It works but i guess i wrote it too long

Is this good code or too long

[rich ice]

if it works, dont fix it
-# (until it becomes a massive issue later)

[twin pivot]

Multiply by time.deltafixedtime and put the entiew thing in fixedupdate

[formal tide]

Do u recommend i should just start develope my own small game and learn on the road. I do small prototypes right now some mechanics and try to learn likr that

[valid violet]

Yes you should start your own game and finish the prototype

[formal tide]

Hmm alright

[valid violet]

I usually use if (Input.GetKeyDown(KeyCode.A)) { } your mthod I see first time

[formal tide]

I should check what all that means

[valid violet]

You can also read the Unity3d tutorials there lot of things you can learn

[formal tide]

This is the old input system i believe. Mine is new input system. 🙂 i dont know the difference tho. I did urs first and it worked fine then i tried new input system

[valid violet]

honestly for me the old looks better 🙂 because u have class with all KeyCode, but it is okay to use any that works

[rich ice]

yeah the old input system is probably better for beginners. the new input just makes things like adding controller support easier (afaik atleast)

[rich ice]

is the script attached to an object?

[manic blade]

Yes

[valid violet]

@manic blade You need to do Input.GetAxis("Horizontal") * Speed and check the Speed value that will move fine for you

I do not remember try 10f if to slow try 1000f

[manic blade]

I did that i put 100 still didn't move

[rich ice]

should still work even without multiplying by speed. if they were just using AddForce then that could be the issue but they're directly setting the velocity

the script looks fine to me. the only issue i can think of is that it just isn't attached

[manic blade]

I can send you an picture it is attached

[rich ice]

sure

could tell us a bit more about the scene aswell

[valid violet]

speed is not needed

it is working fine without speed

[rich ice]

-# sidenote: use screenshots instead of another device. makes the image more clear

[manic blade]

I was trying to fix it didn't work before i added the speed

[rich ice]

everything looks correct. you definitely entered playmode and then pressed A,D or the two arrow inputs

[manic blade]

yes

[rich ice]

oh

i think i spotted the error

[rich ice]

in the screenshot the class is named playermovement

[rich ice]

but this is another script called palyermovement

if it's not that, im officially out of ideas

[formal tide]

In unity project settings from top left then player settings find activated input settings or whatever that called. I changed that to"both" And it worked. I had the same issue but idk if its same issue for u. Maybe u can try

[manic blade]

that was an old screenshot i fixed that

[formal tide]

Alright

[valid violet]

I recreated the logic it is working fine

[rich ice]

could be this. i've mainly used the new input system ever since swapping to unity 6 so i cant really confirm or deny that.

[formal tide]

here i changed this to both now both input system works

[manic blade]

i did that i tried everything that why i came here

[formal tide]

Did u try using Debug.Log so u can see the error

[manic blade]

no

[formal tide]

I would try that to see what is the issue

[wise cairn]

ok so i'm making a 2d side scrolling game and just working on basic movement, how should i move the player? i already have all my code calculating how much to move and rb.position += movement * Time.fixedDeltaTime was working, but apparently i shouldn't do that because it ignores physics? what do i do instead?

[rich ice]

why does the collider have a scale of 5.12? assuming that's the default square sprite, a scale of 1 on the collider should just automatically scale correctly with the object

[rich ice]

take a look at this video

[wise cairn]

ok thanks

[rich ice]

oh wait no

sorry my bad

[formal tide]

Also did u see that Awake() method? Can u change that to Start() Im beginner but i guess that method is not neccedary there

[valid violet]

Did you press the Play button to enter play mode before move object xD?

[rich ice]

right yeah use rb.linearVelocity (or if you're using an older version, rb.velocity) instead

[manic blade]

yes

[manic blade]

i will try

[rich ice]

if you directly change the position of the object i believe it'll cause clipping

[manic blade]

for my it didnt change

[rich ice]

awake just runs before start. i dont think it'll cause any issues in this scenario
(the unity docs has a useful graph explaining it)

[formal tide]

Hmm i never saw it thank u

[manic blade]

i can send an video because i don't know what to do

[valid violet]

delete the player create new one add The Sprite the Rigidbody2D then add the Playermovement hit play and try agian:)

[manic blade]

i will try if it dont work im gonna start some other way

[rocky canyon]

its actually better to have the graphics as a child gameobject

[valid violet]

@manic blade Rename script form playermovement to Playermovement

[rocky canyon]

• Player - rigidbody, collider
  • graphics - sprite

but ya.. something like that

[valid violet]

Your script playermovement.cs it should have same name as inside script

[rich adder]

no longer is that a requirement

but yes its good practice to do so

[rocky canyon]

lol.. it angers me that my classes and scripts no longer have to match

[rich adder]

script.cs
public class PlayerMovement : MonoBehaviour

😆

[valid violet]

try to rename this one maybe will work in older unity it should match

[rich adder]

they are using Unity6 , that doesn't matter rn

what they should do though is not have the Console tab/window hidden

sum like this

[manic blade]

i have uniy 6 and rename it still does not work

[rich adder]

where did you put playermovement component at ?

put logs inside the script and see if thats running at all

[rich adder]

you put logs inside update ? check the console after doing so, press some keys etc.

[manic blade]

how do i do that

[rich adder]

Debug.Log

should've been the first piece of code you should've learned

[valid violet]

Debut.Log(Input.GetAxis("Horizontal"));

[rich adder]

better yet store it inside a variable

float horizontalMove = Input.GetAxis("Horizontal");
Debug.Log($"input value {horizontalMove}");

[valid violet]

when you press <- -> or A D it should log 1 or -1 if it log 0 mean input does not working

[manic blade]

its an dumb question but where should i put it i was only following an video

[valid violet]

inside Update

[rich adder]

like I said, in Update

[valid violet]

@manic blade did you follow this Edit->ProjectSettings #💻┃code-beginner message ?

[manic blade]

like diss

[rich adder]

jesus..

[rich adder]

even the editor is yelling at you , you forgot to put;

that tells the computer , this is the end of a line of code

[manic blade]

i forgot

[tulip relic]

How do you detect when a button is released with the input system?

[rich adder]

Canceled event
there is also WasReleasedThisFrame if you don't use events

[valid violet]

@tulip relic In old Input.GetKeyUp

[tulip relic]

What are you talking about?

[rich adder]

new input system ?
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.2/api/UnityEngine.InputSystem.InputAction.html

[tulip relic]

Also, my PlayerInput is created at runtime without a prefab, so I'm not sure how to assign UnityEvents to it

[rich adder]

wdym "PlayerInput is created at runtime without a prefab"

[tulip relic]

The component is added to the player GameObject from a SpawnManager at runtime

[rich adder]

if you're using the PlayerInput are you using SendMessages mode?

[tulip relic]

I believe so

[rich adder]

I usually use events, you can probably just check
inputValue.isPressed is false in the method for the action

[tulip relic]

What event is called when the button is released though

[rich adder]

for events its .canceled

[tulip relic]

What method name

What is the name of the function

[rich adder]

thats not events then.. in SendMessages mode, the method name is always the name of the action prefixed with On

[tulip relic]

In SendMessages mode, OnAttack is only called when the attack button is PRESSED, not released

[rich adder]

eg cs OnAttack(InputValue value){ if(value.isPressed) //stuff else //was released

[tulip relic]

The //was released will never execute because OnAttack(InputValue value) is only called when the attack button is pressed

[rich adder]

pretty sure it gets called on both

[tulip relic]

It doesn't

I'm looking at it right now

[rich adder]

whenever I used it, it always called the method twice, once on pressed/held and once more released

[tulip relic]

I used

    public void OnAttack(InputValue inputValue)
    {
        print(inputValue.isPressed);
    }

and it only prints True

[rich adder]

you might have to switch the action mode then

[tulip relic]

Where and to what

[rich adder]

whats it currently set to ?

[tulip relic]

Are you talking about where it's set to "Button"?

[rich adder]

in the actionmap, is it set to button?

[tulip relic]

In the Input Actions Editor, it's set to "Button"

[valid violet]

isnt it action.started += context => Debug.Log($"{context.action} started"); action.performed += context => Debug.Log($"{context.action} performed"); action.canceled += context => Debug.Log($"{context.action} canceled");

[tulip relic]

What's action and where does that code go

[valid violet]

InputAction class

like this var action = InputSystem.actions.FindAction("Move"); as I understand and action.canceled //triger when button Up

[rich adder]

try setting it as Control ValueType - Any

[rich adder]

if they were using events, this is event based as mentioned earlier you would use canceled

[tulip relic]

I'm not sure what this means

[rich adder]

instead of Button, set it to ValueType

it should give you the secondary event of released

[tulip relic]

It does, thanks

[rich adder]

actually for button iirc you can also add the Interactions for release

[rocky canyon]

you can also set up Interactions per action

[rich adder]

🦥

I was just sending that and you beat me to it @rocky canyon 😁

[rocky canyon]

💪 i just happen to have it open..

still dippin my toe in.. but darn is this thing universal af

[rich adder]

so many options 😵‍💫

[rocky canyon]

i know.. its quite overwhelming if im being honest

been practicing with just a couple of buttons only

[valid violet]

The new input system looks so heavy, not sure it is worth to use it.

[rocky canyon]

clear it out and start fresh.. and its not soo bad anymore

[rich adder]

I would not use anything else. old Input class is garbage in comparison

technically new input can be just as straight forward if using traditional polling

[rocky canyon]

after a bit of fiddling i got a decent little system set up ^

and if u want.. u can still poll for inputs with it..

[rich adder]

Update(){
  if(Keyboard.current.spaceKey.wasPressedThisFrame)
        {
            // input.getKeyDown
        }```

[rocky canyon]

ezpz 🍋 squeezie

im still a bit intimidated by the axis' inputs but it'll be fine

"composites" rather

[valid violet]

Okay maybe worth for action pc games. And not worth for mobile games (custom control usually).

[rich adder]

totally false. this is actually especially good for mobile especially with all the custom Tap and other Interaction modes

you would need to code those manually with the old input

slowtap, multi-tap etc.

it also supports a variety of controllers and input devices

[valid violet]

Yes, I used to setup mobile input manually and it wasn't hard? So new input is easier to do such operations?

[rich adder]

In my opinion yes, and I used old input for years before taking the plunge and never looking back

it can be overwhelming because so many ways to do something in it

once you wrap your head around all the features you will pretty much love it

[valid violet]

For example won't u need to use native mobile control if you develop swipe combat system I think it won't be available for default in new input

[rich adder]

swipe is done the same way you do it with the old input system, track the magnitude between 1 point to another

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

many ways to get events such as TouchStart etc.

[valid violet]

So this is point I do not need any additional knowledges to create any mobile control I need, but I will need to study a lot to implement new input for mobile game, and I will need to know how to use native mobile input even if I use new input.

[swift elbow]

is there a way to negate the destruction of an object in OnDestroy() (or in a different built-in method)?

i ask this under the assumption that OnDestroy() triggers before the object is actually destroyed

[rich ice]

you could store an instance of an object and then instantiate that instance when it get's destroyed

i think i remember something about this causing issues though. so i'd avoid doing that if you can.

[swift elbow]

ah that's a neat idea, but then any references to it would become and stay broken

[rich ice]

oh good point, that would work with prefabs but not individual instances.

i think so atleast, might have to test that myself

if you dont mind me asking, why are you trying to do this anyway?

[swift elbow]

it was just a random thought that intrigued me. i dont really need this for anything

[wise cairn]

when i use that for some reason the built in gravity breaks

[rich ice]

you might be setting the velocity instead of adding to it. you can also just do like = new Vector2(movement, rb.linearVelocity.y)

[eternal needle]

create your own method, then this method can add logic basically choosing if it should call Destroy or not

[wise cairn]

is linearVelocity not conserved? does it only last for one frame?

[swift elbow]

yeah im sure i can go for that approach, but i was wondering if there was anything easier by using built-in methods

[rich ice]

assuming you have some kind of drag, the velocity would slowly decrease.

[wise cairn]

what does drag mean? sorry if it's obvious, i have an idea but i'm just making sure

[rich adder]

setting linear velocity overrides all that

[wise cairn]

yeah but the whole thing they were saying is to not set it

[rich ice]

basically, anything that naturally slows the object down. usually it's linear damping although it could also be friction

[rich ice]

oh true, i completely forgot about that

[wise cairn]

ok so still how should i move the object? adding to linearVelocity just makes it add up and move obscenely fast

[rich adder]

show code

[rich ice]

depends on what you're going for. honestly im not the best at this myself. but i think most people usually add to linearVelocity and then cap it on the required axis

[wise cairn]

rb.linearVelocity += movement; is what i was doing

[rich adder]

what are you trying to achieve ?

[wise cairn]

im trying to move the object by movement every frame

[rich ice]

i believe you would want something like this

if (Mathf.Abs(rb.linearVelocityX) < maxSpeed)
    rb.AddForce(movement);

[rich adder]

what you wrote will keep adding onto the velocity and potentially go on faster and faster forever as you do movement

[wise cairn]

yes i'm aware that's why i'm asking what to do

[rich adder]

you can do AddForce as shown above, or use .linearVelocity but instead of += just assign
= instead

[wise cairn]

then we're back to the issue of overriding gravity though

i'll just do the above solution

[rich adder]

then exclude the y in the linearVelocity

[wise cairn]

ok

[rich adder]

if 3d
rb.linearVelocity = new Vector3(horizontalMove, rb.linearVelocity.y, verticalMove)
or
Vector3 velocity = rb.linearVelocity ; velocity.x = horizontalMove; rb.linearVelocity = velocity;

if you're on 2D you can simply assign rb.linearVelocityX = horizontal

[wise cairn]

ok thanks

[queen adder]

Is it better to add RigidBody to the sprite rather than creating an object separately for it?

[sour fulcrum]

"it depends" but usually you'd actually wanna do the oppisite and have your visuals exist under the logic

[queen adder]

Elaborate.

[sour fulcrum]

Well usually the "logic" that actually does stuff like a rigidbody would be the parent

and as the visuals are kinda a "reaction" to that logic, they would be parented under the logic as a child

[queen adder]

So basically Empty -> RigidBody2D component in Empty -> Sprite in Empty -> Animator in Sprite?

[eager spindle]

Player gameobject has Rigidbody2D, ,Collider2D, PlayerMovement
Child GameObject has Sprite Renderer

Depending on your games structure you can also choose to put your Collider2D in the child gameobject

[daring sentinel]

Quick question but with unity timeline, is it possible to mute and unmute track groups via scripting. Pretty much I'm just sorting the dialogue for my game where I have the audio and text in separate track groups, and want to mute and unmute specific track groups, that contain different audio clips in the timeline - depending on the player's dialogue option selected.

I've been looking at the API and I'm so confused

[sharp bloom]

Is this applicable to 3D as well?

I mean having your Mesh Renderer on child object

[eager spindle]

Yep

[daring sentinel]

Hey sorry, if you're not too busy, would you mind answering my question?

What I'm confused about is how to go about muting and unmuting track groups via scripting, like I know that trackasset refers to tracks in timeline but I was looking on unity forums and they have code going on about timelineasset, but TrackAsset doesn't look like it inherits from TimeLineAsset in Unity's API?

[eager spindle]

to clarify this is about audio right?

hmm i havent come across this track groups yet

both TrackAsset and TimelineAsset inherit from PlayableAsset

https://docs.unity3d.com/2018.1/Documentation/ScriptReference/Timeline.TrackAsset-muted.html

It looks like muted can be set

set this to true

[nimble apex]

sry i got a little brainrotten now

currently i have a lobby UI , the UI will list out available rooms, because there will be many rooms, i had pooled the UI elements that display the room info , with unity iobjectpool

i have an option for players to display the amount of room info that they want , by 50/60/70/80/90/100 at a time , lets call it int maxQuery

one way the lobby UI works, is to clean out all existing element UI when player change their "maxQuery"

so , for cleaning the element UI , which is better

PoolManager.Instance.Clear(ObjectPoolType.SessionDetail);
AllRoomsAvailable.Clear();```

```cs
            foreach (GameObject element in AllElement)
            {
                PoolManager.Instance.Release();
            }```

or i dont need to clean out the maxQuery?

[eager spindle]

In the background, both essentially do the same thing. The first is clearer though, I'd use that.

[nimble apex]

if they did the same thing that will be easy , i afraid it will actually extinguish the object and the pool need to instantiate it again lol

ty 👍

[daring sentinel]

So what I was trying to do was that I have the control and audio tracks in a group to represent each 'chunk' of the script. What I was trying to do was mute and unmute each of these groups through a script, depending on the player's option chosen, if that makes sense.

What I'm really struggling with is trying to understand how I need to access the tracks to mute them.

Let me know if I need to be more clear, soz.

At the moment I'm just trying to have it work with one dialogue option, because then I can just put it altogether after this and actually start building the game

I was thinking of doing it this way because if I have 3 choices per scene then I can just unmute and mute the groups accordingly.

[shut flame]

hello

so i wanted to handle input

and although following the documentation

it used an outdated method

is there any source that uses the new input method

preferably a website or in text format

[eager spindle]

input system?

[shut flame]

yes

[eager spindle]

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

[shut flame]

oh thanks

was using this

https://docs.unity3d.com/ScriptReference/Input.GetMouseButtonDown.html

[eager spindle]

Yep this is for Input Manager, the old one. In Unity 6 the default is Input System

if you want to learn about input system youll need to look for that keyword specifically

[shut flame]

oh

thanks

[queen adder]

I have a problem that the player dashes only in right direction (therefore I have a code that should fix it in lines 62-66)
my script: https://gist.github.com/bielo1656/b295d27c7191ddebe652bb69e2fe0724#file-gistfile1-txt

[rocky canyon]

the top if statements run.. thats fine.. (but then hwen u get down to crouching input it also runs... same frame..

so if ur not crouching.. its gonna go right back to 5,5,5

doesn't matter what ur horizontal input is

could do something like

if (horizontalInput > 0.01f)
    facingDirection = 1f;
else if (horizontalInput < -0.01f)
    facingDirection = -1f;```

and then use facing direction multiplied w/ ur X scale in the crouch method

or.. do all ur inputs together in a set of if elses

[frigid sequoia]

Hey, can I not get to see this list on the editor and add elements to it???

I was hoping I could

[slender nymph]

StatAttribute must be serializable

[frigid sequoia]

Like the class?

How do I declare that?

[queen adder]

Can I ask a question: why do I have to multiply my X axis with my facing direction for crouching?

[naive pawn]

https://docs.unity3d.com/6000.1/Documentation/Manual/script-serialization-rules.html

[queen adder]

since crouching is just changing in the scale

or is it?

[rocky canyon]

b/c its overwriting the X

ur horizontal makes it 5 or -5..

but then ur crouch overwrites it right back to 5

see both conditions are 5

soo.. it really doesnt matter what ur horizontal sets it to.. b/c u just overwrite it back to 5 anyway..

[naive pawn]

both the flip and crouch should probably just be modifying the relevant part instead of overwriting the whole thing

[rocky canyon]

true.. thats another option ^

new Vector3(transform.localScale.x, 5, 5);

or new Vector3(transform.localScale.x, 2.2, 5); for the other condition

the entire Update() runs in a single frame.. (all the code).. u cant set 1 thing at the top.. and then something different at the bottom.. and expect it to show different results

if u walk thru ur code one step at a time you'll understand the issue...
pretend ur pressing Left and Crouching at teh same time.. then write down what the X of the local scale ends up as.. and what it should end up as

[nimble apex]

    public GameObject Get(ObjectPoolType poolType, Transform parent)
    {
        GameObject obj = AllObjectPools[poolType].Instance.Get();
        obj.transform.SetParent(parent,false);
        
        return obj;
    }```
```cs
public void Clear(ObjectPoolType poolType) => AllObjectPools[poolType].Instance.Clear();```

this is the get and clear function of my pool , somehow the clear function is not working tho

it can get object properly

release is also working

[naive pawn]

wdym by "not working"

[nimble apex]

when i call the "clear" function, all the object that spawned from the object pool should be released or destroyed right?

but its not

wait

yep its not clearing

[wintry quarry]

I don't think it destroys any objects

it just makes the objects not associated with the pool anymore

[nimble apex]

ohhhh

[wintry quarry]

Although I do think it should run your actionOnDestroy if you provided one when you constructed the pool

did you?

[nimble apex]

private GameObject CreatePoolObj() => Instantiate(Prefab);

    private void OnGetPoolObj(GameObject poolObj) => poolObj.gameObject.SetActive(true);

    private void OnReturnPoolObj(GameObject poolObj) => poolObj.gameObject.SetActive(false);

    private void OnDestroyPoolObj(GameObject poolObj) => Destroy(poolObj);```

[wintry quarry]

what about the line where you create the pool?

[nimble apex]

i do have the basic 4 functions

    public IObjectPool<GameObject> Instance
    {
        get
        {
            if (constructedInstance == null)
            {
                constructedInstance = new ObjectPool<GameObject>(CreatePoolObj, OnGetPoolObj, OnReturnPoolObj, OnDestroyPoolObj, checkPool, DefaultPoolSize, MaxPoolSize);
            }

            return constructedInstance;
        }
    }```

[naive pawn]

what's with the .gameObject lol

leftover code?

[wintry quarry]

ok yes this should destroy the objects theoretically

[nimble apex]

i have another version of object pool but its integrated with netcode

so the code are very different

[nimble apex]

i think so, but its not, i think i will double check

!code

@wintry quarry this is the update function of the UI, here it spawns the element UI and remove it if necessary

the get function is working

also the filter are properly populated

[nimble apex]

        foreach (SessionDetail element in AllRoomsAvailable)
        {
            PoolManager.Instance.Release(ObjectPoolType.SessionDetail, element.gameObject);
        }```

i just gonna loop over the gameobject instead...

it does work this way tho

alright thank you

[formal tide]

Guys. Should i keep continue writing in same c# file in unity or should i create another one? For exampld i made jumping mechanic for my character i gave it 2 jumping limit until it hits ground collision now i will code character WASD movement. Im not sure if i should continue from same c# file or create another

[nimble apex]

do iobjectpool has methods that can return all existing/active objects that it instantiated and not yet disposed(destroyed)?

not including released(inactive) objects

[polar acorn]

Each script should do one thing. How you define a "thing" is mostly up to you. Is jumping part of movement or is it a different action? That's up to you to decide.

[formal tide]

This is the code. I guess i will write another c# code for WASD controls

[slender nymph]

!code
also just FYI but that last line of Update is not within the scope of the if statement (not that it really makes any difference in this case)

🤣

[slender nymph]

yes, i am aware.

[formal tide]

Is there a limit inside update

Im trying to learn thank u for info

I will researxh

[slender nymph]

this question does not make a lot of sense. what do you mean by a "limit inside update"?

[formal tide]

I will change the question and makr it clear. what should i do to fix it

[polar acorn]

Fix... what

[slender nymph]

i don't even know what you are asking, hence the reason i asked for clarification . . .

[formal tide]

I was talking about this

Is there any issue on my code so i can fix it

Or is it fine

[slender nymph]

i mean, it's currently fine, but if you don't know how to include multiple lines inside the scope of an if statement, perhaps start by learning the basics of c#. there are beginner courses pinned in this channel

[polar acorn]

Are you having any problems with it

[formal tide]

Code works fine inside game but i was curious if its written wrong

[formal tide]

Yes i following them

[slender nymph]

the way you have formatted it, it seems you expect that last line to be included in the scope of the if statement (which is it not)

[hallow acorn]

break goes out of the current "if", "for" etc right? so if i have 2 stacked ifs and i write "break;" in the inner one it would go back to the outer if?

[formal tide]

This?

[slender nymph]

yes

[formal tide]

Thanks

[slender nymph]

c# is not python. white space does not matter, just because that last line is at the same indentation as the one before it does not mean it is in the same scope

[naive pawn]

it seems like this is something you've discovered but not understood, given the duplicate condition

[formal tide]

Thank u.

[naive pawn]

you should probably go through some beginner c# resources, there are some pinned in this channel

[formal tide]

Yes i need to study abt if else again

Its good to see my mistakes and see what should i study again

Hi!
I don't know if this is more beginner code or not but I need help with a code snippet that make's a lot of sense in my head but is not working for some reason.
I'm trying to use the new input system to make my character sprint, but it is isn't sprinting. Help pls

[vapid mesa]

hello guys, i try to code a 2d Top down view game and my kinematic character go througt object and d'ont car about it, thank you so much if someone can help me !!

[wintry quarry]

my kinematic character go througt object and d'ont car about it
Yeah that's pretty much the definition of kinematic objects

working as expected

[vapid mesa]

how i can do collision to dont allow going througt

[wintry quarry]

make it dynamic

and set the velocity instead of using MovePosition

[vapid mesa]

can u explain i don't understand well

pls

[wintry quarry]

what part are you confused by

[vapid mesa]

i dont understand what i need to change else of kinematic to dynamic

[wintry quarry]

Change your code so it sets the Rigidbody's linearVelocity instead of calling MovePosition

[vapid mesa]

i change this so ?
movement.x = Input.GetAxisRaw("Horizontal"); // -1, 0 ou 1
movement.y = Input.GetAxisRaw("Vertical"); // -1, 0 ou 1
movement.Normalize();

[wintry quarry]

nothing there needs to change

You need to change the MovePosition part

[vapid mesa]

okayyy

this
rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);

[wintry quarry]

rb.linearVelocity = movement * movespeed;

[vapid mesa]

thksss

it say as if linearvelocity doesn't exist

[rich adder]

if you're using Unity 2022 or less, its just .velocity

[wintry quarry]

yeah I assumed you were on Unity 6

[vapid mesa]

most recent version of unity are better ?

i'm pretty sure there is something else wrong but since yesterday i can't find it

it doesn't work with dynamic

[rich adder]

wdym "it doesn't work with dynamic " ?
