Maybe describe what you're trying to do?

[clear river]

I have created a ScriptableObject named SOWorld, and I built a ScriptableObject array named SOWorldDataSet[]. The World scriptable object has a Sprite named encounterBackground.

I have a Canvas with a GameObject called Battle BG which includes an Image and a Canvas Renderer.

BattleHandler.cs should take the encounterBackground sprite from this scriptableobject Worlds, and apply it to the gameobject Battle BG.

Somehow I'm doing this very wrong. What's the best way to make this connection?

[honest haven]

i didnt really want the battle starter script being a instance if thats what you mean as static because each enemy would have on on the scene

[fossil tree]

make my variable public Transform target; be = at my gameobject balloon in the previous screen

[ivory bobcat]

Why? Is there any particular reason why you'd want the prefab to reference an object that will not exist in the next scene?

[swift crag]

a static member is literally the exact opposite of an instance (:

You would stash the list in a static field, then read that list in the battle scene

[fossil tree]

because i need the transform location of my target for my clone

[swift crag]

public static class BattleData {
  public static List<Enemy> enemies;
}

a minimal example

[swift crag]

explain what you are making your game do

[ivory bobcat]

Save the necessary data and use the data elsewhere - the position.

[swift crag]

ignore the code and the details

what is the game going to do?

[honest haven]

ok cool thanks, so i can use a static list in the battle starter, and call it in another scene? does static get stored in unity memory or somthing

[fossil tree]

a other script spawn homing missile and the target thing is for follow the player balloon

[clear river]

sits and waits for his turn - everyone is puzzling on other requests

[swift crag]

Okay, so you need to assign a reference to the missile (so that it knows where the balloon is) after you spawn it

https://unity.huh.how/references/prefabs-referencing-components

Have a look at this page

[swift crag]

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

A static member (field, method, etc.) is not attached to instances of the class. They're part of the class itself.

A major effect of this is that you can access static members from anywhere, since you just need the class name

BattleData.enemies = ...

[ivory bobcat]

Log the value and see if the function is called. You'll also see what the value is and why it might not be doing what you're expecting it to be doing.

[strong wren]

so just Debug.Log(Health.value);?

[clear river]

Where does Debug.Log show up in the interface?

[swift crag]

it writes to the Console window

[strong wren]

Console

[clear river]

I tried to use this earlier but the app was full screen

[strong wren]

here

[clear river]

I assume since it's a log it should go somewhere even after it closes

[strong wren]

i just did that and well it does what i told it, i changed the value to 5 then it told me that in the console

[clear river]

I think I am missing that tab. I'll try to get it back

[ivory bobcat]

The console won't clear after running unless explicitly

[swift crag]

Window > General > Console

[clear river]

Cool.

[swift crag]

that will reopen it

[strong wren]

go to window then general the click on console

[clear river]

Also, when you have the time I have a main question

[swift crag]

ask it!

[clear river]

It's back up at 7:50

[ivory bobcat]

Did you place it in Update and did the value decrease?

[clear river]

Should I repeat it?

[strong wren]

yes i placed it in update and no the value only deacreased when i deacreased it manually

[clear river]

Here it is

[ivory bobcat]

Show your update method

[swift crag]

this sounds fine; what is the problem you are having?

[strong wren]

 {
     Debug.Log(Health.value);
     Health.value -= 1 * Time.deltaTime;
     ScoreCounter.SetText("Score: " + Score);
 }```

[swift crag]

are you unsure how to give a SOWorld to the BattleHandler ?

[strong wren]

the ScoreCounter Thing you can just ignore that works as planned

[ivory bobcat]

Can you show the logs?

[clear river]

I am a 30 year programmer but I am new to unity.
My various attempts to drag-and-drop, set sprites and images... are all failing me

I do not know the basics. =w=

[swift crag]

If you're experienced with programming but don't know Unity's interface, I'd check out the documentation

https://docs.unity3d.com/Manual/UsingTheInspector.html

[ivory bobcat]

Remove 1 *

[swift crag]

the whole "Working in Unity" section will be useful

[strong wren]

that gives me an error

thats why i added the 1

[swift crag]

and what was this error?

[ivory bobcat]

What error?

[swift crag]

You have to actually read error messages..

[strong wren]

i also tried to have it like this

[ivory bobcat]

Subtracting zero isn't going to be very productive

[swift crag]

well that's just completely mangled syntax

[swift crag]

you didn't add 1 *

you added 1

Health.value -= * Time.deltaTime; would produce that error

get rid of the * operator.

[ivory bobcat]

You've done more than just remove 1 *

[strong wren]

oh theres not an error no more

i always tought u always have to * by Time.deltaTime

[swift crag]

you multiply by deltaTime in many cases

[clear river]

My last attempt saw me create an Image in the BattleHandler.CS named BattleBack, then access that image via dropdown in the UI and link it to the actual background image on the canvas... but when I went to say "battleback.sprite = WorldDataSet[a].Worlds.encounterBackground.Sprite;

The UI said 'Images do not have sprites, you silly bean.'

[swift crag]

you don't literally slap * Time.deltaTime everywhere

[strong wren]

oh ok

well that still didnt fix it

[swift crag]

This is trying to apply the unary (one-argument) * operator to Time.deltaTime, which is an error

If you just want to subtract one per second, do Health.value -= Time.deltaTime

If you want to subtract by some other rate, do Health.value -= rate * Time.deltaTime;

[clear river]

Also I just made many typoes. Sorry

Pseudo

[strong wren]

oh

so i was subtracting by 1?

[swift crag]

You probably have the wrong using directive

There are a lot of classes called Image

[ivory bobcat]

If value is an integer, it'll not retain the accumulated decrements.

[clear river]

Uhhhoh

Okay thanks

[swift crag]

You want using UnityEngine.UI;

[clear river]

Is there a better way to do it then the general method I'm attempting?

[swift crag]

the code looks fine

[clear river]

Or do I have the best/a "good enough" method? I guess it's ok

Okay, let's go learn more about the various types of Images

Thanks again

[lost hamlet]

There are only 2 Image classes by default. The Image component and the UI Toolkit Image

[swift crag]

oh good heavens!

[strong wren]

still didnt fix it btw

[swift crag]

#💻┃code-beginner message

[lost hamlet]

Uh System.Drawing never shows up when I do stuff

[swift crag]

maybe your IDE is smarter than mine :p

this is VSCode

[lost hamlet]

Yeah I use VSCode too

[ivory bobcat]

I'm assuming Health value is an integercs private float value;``````cs //Start value = Health.value;``````cs //Update value -= Time.deltaTime; Health.value = value;

[clear river]

... typoes?

[strong wren]

so i should change it to a float?

[clear river]

Is Unity case sensitive??

[lost hamlet]

What exactly in Unity

[strong wren]

Yes

[paper peak]

C# is very case sensitive

[strong wren]

coding in unity is Case Sensetive

[clear river]

:[ I KNOW WHAT I DID

Thank you.

[paper peak]

Is it possible to change a public variable of a script from another script that resides in another gameObject?

[lost hamlet]

If you get a reference to that GameObject yes

[molten dock]

case Sensitive

[paper peak]

How do i access the script after referencing the gameObject?

[lost hamlet]

<reference>.publicMember

[ivory bobcat]

Either reference it as the correct type or call Get Component

[lost hamlet]

Oh sorry

GetComponent indeed

[strong wren]

uhm i dont have a health value 😭 the Health is the slider

[swift crag]

Show us the entire script.

I need to see what you are actually doing.

bruh so ur saying that i was so close to fixing this code my self?
i tried doing the value = health.value and the Health.value = value myself but i tought that it would be wrong

[swift crag]

https://unity.huh.how/references

Have a look here.

[ivory bobcat]

I accounted for that thus why I suggested you make a float variable to retain the precision

[swift crag]

You probably want to create a serialized reference, where you drag one object into another object's inspector

https://unity.huh.how/references/serializing-component-references like so!

[ivory bobcat]

You'll want to update the float variable if you change the health's value elsewhere

[ivory bobcat]

I'm guessing you had whole numbers checked.
https://docs.unity3d.com/2020.1/Documentation/Manual/script-Slider.html

[strong wren]

yep

[paper peak]

Is there someway i can change a gameObject's scale without having its children be affected as well?

[ivory bobcat]

Container
-Renderer
-Everything Else

If you separate the renderer, you'd be able to modify it alone without affecting everything else

These would all be Game Objects

[ivory bobcat]

Have it unchecked and you won't need to maintain any extra variables. You'd be able to simply decrement itcs Health.value -= Time.deltaTime;

[atomic sierra]

did unity remove their new monetization policy?

[lost hamlet]

They reworked it

And this is a code channel

my apologies

[fossil tree]

someone can explain me why when i build my game i dont see the wind in the horizontal side and why my player are soooo slowww https://cdn.discordapp.com/attachments/1149752436681080952/1238893268901560452/20240511_183803.mp4?ex=6640f0c4&is=663f9f44&hm=7fb6ea930a3a95df3c1e8b18c8d74dfd9bad819fea7430b91468b579e984d781&

[rich adder]

depends on the code etc.

video alone doesn't help

[fossil tree]

but the camera dont depend of the code...

[molten dock]

have you guys noticed ontriggerenter sometimes responding to non trigger collilders

[rich adder]

depends, how do you move the cloud, cam whatever

[fossil tree]

i dont move the cam and the cloud move by himself

[rich adder]

only if neither has a rigidbody

[rich adder]

show how you move cloud

[fossil tree]

using UnityEngine;

public class cloud_controller : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(move());
    }

    // Update is called once per frame
    IEnumerator move()
    {
        while(true)
        {
        for(int i = 0; i < 140; i++)
        {
        transform.Translate(new Vector2(0,-0.2f));
        yield return new WaitForSeconds(0.05f);
        };

        transform.position = new Vector2(Random.Range(-10, 10),9 );
        }
    }
}

[willow scroll]

What is that

[storm pine]

Your canvas scaler is set to Scale with screen size or constant pixel size? Your aspect ratio is different on each play, so the wind effect just stays out of the screen

[willow scroll]

• 1. Why are you not using the default naming conventions?
• 2. Why are you moving the cloud in a Coroutine?
• 3. Why are there no serialized values?

[fossil tree]

i dont use canvas i dont have ui

[rich adder]

what is up with that for loop

that too me seems 100% a choppy behavior waiting 0.05 each iteration

[fossil tree]

that not my problem i know my code is bad

[rich adder]

how you know thats not the problem

[willow scroll]

Right, that my problem

[rich adder]

yet look how it behaves

sum random 140 times for loop inside a while loop

weird

[fossil tree]

ty for the help

[rich adder]

just put this in Update
transform.Translate(Vector2.down * moveSpeed * Time.deltaTime)

you don't need anything else

[fossil tree]

but i need to tp back the cloud

[willow scroll]

🔃

transform.Translate(moveSpeed * Time.deltaTime * Vector2.down)

[rich adder]

back the cloud ?

wdym

[fossil tree]

like tp on top

[willow scroll]

Then check for its position to be sure

Basically have a bottom edge, and when the position <= edge, move the cloud to the startPos

This way you don't have to care about its speed

[fossil tree]

how can i get the position of my cloud

[willow scroll]

What?

[fossil tree]

ok no i got it

[willow scroll]

I hope so

[fossil tree]

ok i patch this but the problem is the same

[rich adder]

1. send current code.
2. show what is currently happening

[fossil tree]

i think i understand why my balloon are slow

i dont * by time.deltatime

but how can i do for the camera?

[rich adder]

wdym for the camera?

are the objects moving down or is the camera moving up

unclear

[fossil tree]

look i dont have the same view when i play and when i build

[crystal vale]

Hi I’m new to Unity and I just want some tips for the Visual Scripting since I have worked a lot with Scratch when I was younger.

[rich adder]

you're not answering, and I think extracting info is a waste if time. So idk

i'm not in mood to play 20 question, you should #854851968446365696 on how to properly get help here by being clear and descriptive

[eternal needle]

#763499475641172029

[fossil tree]

its the object moving down if you talking about cloud like i say before my camera dont move

[rich adder]

so if it doesn't move why the hell would you want to apply time.deltaTime to it

[fossil tree]

i dont say that 😭

i patch the problem with time.deltaTime

[storm pine]

As far I know if you dont use the UI you have to consider the screen width (in your case) and height to ensure your objects are always inside of it

[fossil tree]

but my other problem is my camera screen size are not the same in build

[fossil tree]

yes i say i have patch the speed problem with * time by time.deltaTime

sry if i have bad explain i'm not english

[rich adder]

you asked how you can do it for the camera

hence why I said, why would you want to do it to camera if its not moving

[fossil tree]

yes mb

[storm pine]

Because when you are playing it on the Editor have the Free Aspect set ( and it looks so extended) and when you play on fullscreen is 16:9 frequently

[fossil tree]

oh yes its true i forget that

[flint python]

Hi, i am making a space shooter game, and I am uncertain whether to use object pooling or instantiate + destroy.

So far I know object pooling helps performance, by having duplicate objects ready and just reusing them, but if I want to shoot a bullet every 0.5s and deactivate the current bullet when it's outside the screen, for this I will need to create 50+ or more duplicates.

If my game has many bullet types, I will need to create thousands of duplicates, is it worth having better performance but a larger game size?

Please give me some advice, thanks.

[rich adder]

Pooling hands down

make a prewarm of 150+ and you should be fine

Instantiating and Destroying will cause much more garbage

[wintry quarry]

Can the pooled objects be reconfigured to be different bullet types easily?

If so do that

Otherwise make a pool per type

[storm pine]

you need a good structure first. Talking about bullets, you need a parent class called Bullet and some subclasses that inherits from Bullet (maybe ExplosiveBullet, FastBullet...) so you just have a pool with objects of type Bullet, but at the end each one can be from a different inherit class

[flint python]

Thanks all

[rich adder]

ScriptableObject is also another way to just make the Bullet class flexible with multiple data

[ivory bobcat]

Why not both.

[blazing warren]

I'm trying to make a very basic player character for my VR project. I want the player to have a ship model attached to them, which matches the players position and head rotation (minus up and down). But I'm not sure what the model of the ship should really be parented to

Currently my setup is like this, with the "Blue Viper" prefab being the ship model. Everything else is self explanatory I think. Does this parenting hierarchy seem logical?

[swift crag]

perhaps you should just copy the head's position and rotation with a script

The XR Origin is the center of your playspace. Parenting to that means the ship is not following the player's head

[lost hamlet]

Wouldn't player camera fit the best then?

[blazing warren]

Should the XR Origin not be moving along with the player when the player moves ingame (not in real life)?

[lost hamlet]

No

[tough cave]

I made a Gameobect/prefab that was outisde the canvas. But now I want it inside the canvas visable. How do I make the gameobject visable in my canvas? I hoped adding the Canvas renderer would fix that lol. but no.

[rich adder]

just make a new object in the canvas

your object is still in Transform and not Rect Transform which is what happens when it becomes part of canvas

[blazing warren]

So to be clear, you think the XR Origin shouldn't move when provided ingame input like from a controller? I'm not referring to head movement IRL

[honest haven]

Cannot instantiate objects with a parent which is persistent. New object will be created without a parent. if (activeBattlers[currentTurn].isEnemy) { activeBattlers[currentTurn].ChildPartickleEffect(activeBattlers[currentTurn].zoneHighlight); } the parent object is now an instaticated prefab. but i dont understand the error

[fluid glen]

I went on unity version control once now I can’t get rid of it, how do I get rid of it?

[lost hamlet]

Oh yeah in that case it should move I think? Tho I don't know about this package you're using

[blazing warren]

I believe it's called the XR Interaction Toolkit. The XR Rig might be considered a starter asset from it, I'm not sure

[rich adder]

which line ?

[honest haven]

i have two errors

[rich adder]

show the offending line

the Instantiate

[honest haven]

line 654

[rich adder]

what is ChildParticleEffect() method

[honest haven]

yep two secs

[rich adder]

what does that underline yellow on transform say

[cursive hinge]

if i use paint trees i seem to lose the tag of the tree prefab, how else can i check if the object is a tree?

[honest haven]

sorry what yellow line

[rich adder]

ohh

[honest haven]

i found this, could it be thins

[verbal dome]

Looks liketransform belongs to a prefab

[rich adder]

but ur not passing the prefab

ahh that might do it

[honest haven]

thats where im lost i dont understand

but the prefab is a game object, so would it belong to the gameobject

[verbal dome]

You are calling this method on a prefab, not an instance

Petsistent = prefab

[honest haven]

So what would be the fix

thats good to know 'Petsistent = prefab' thanks

[verbal dome]

Dont call ChildPartickleEffect on a script component that is on a prefab

Use an actual instantiated object

You are trying to parent it to a prefab, that can't work

If it's still unclear, show how you are calling that method

[honest haven]

    {
        foreach (var battlers in StaticBattleEnemys.enemies)
        {
            activeBattlers.Add(battlers.gameObject.GetComponent<BattleCharacters>());
        }
        
        if (cubes.Length == StaticBattleEnemys.enemies.Count)
        {
            for (int i = 0; i < cubes.Length; i++)
            {
                // Assign the enemy to the cube's position
                Instantiate(StaticBattleEnemys.enemies[i], cubes[i].position, Quaternion.identity, cubes[i]);
            }
        }
        else
        {
            Debug.LogError("Number of cubes does not match number of enemies.");
        }
    }``` So my game objects are instantiated objects of a prefab

[verbal dome]

But where are you calling the ChildPartickleEffect method from?

[verbal dome]

Oh here

[honest haven]

So these SS level 1 clones hold a script called BattleChars

thats where that method is

[verbal dome]

Looks like you have added prefabs to activeBattlers

[verbal dome]

You should add the instantiated objects instead

[honest haven]

yes

let me expalin

so a npc holds a script called Battler Starter it holds a list of BattleCharcters(scripts). Im using a Static Class to pass this to a new scene

Then on my battle manager im Adding the static list to a cleared New list

then im getting this error

so yes they are prefabs to start off with then i instaciated them in the battle scene

[verbal dome]

Ok but again, activeBattlers should have the instances, not the prefabs

How are you adding stuff to activeBattlers?

[honest haven]

this one here

[verbal dome]

So they come from battlers

[honest haven]

2 secs let me make a video

[verbal dome]

I mean StaticBattleEnemys.enemies

And those are prefabs. Dont do that

[honest haven]

yes those are prefabs

So the goal was to pass active batters to the battle scene .ie the models and attached scripts

[verbal dome]

Instantiate returns the newly created object. Add the BattleCharacters from that, instead of from the prefab.

[honest haven]

i understand, so the ref from the Instantiate, use that?

Instantiate(StaticBattleEnemys.enemies[i], cubes[i].position, Quaternion.identity, cubes[i]);

make this a new list

and do my work to that?

[verbal dome]

Something like this cs foreach(var battlers in StaticBattleEnemys.enemies) { var instance = Instantiate(battlers); activeBattlers.Add(instance); }

[honest haven]

i have a error

but somthing like that

yes

thanks

Hey guys :D i need help On unity with my game

I basicly need a object to always follow another object

using System.Collections;
using System.Collections.Generic;
using System.Runtime.CompilerServices;
using UnityEngine;
using UnityEngine.UIElements;

public class player_move : MonoBehaviour
{
public GameObject bullet;
public float jump_power = 1f;
Rigidbody2D RG;
// Start is called before the first frame update
void Start()
{
RG = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update()
{

    if (Input.GetButton("Jump"))
    {

        RG.AddForce(Vector2.up * jump_power, ForceMode2D.Impulse);

    }
    if (Input.GetKeyDown(KeyCode.R))
    {
        GameObject newbullet = Instantiate(bullet);
        newbullet.transform.position = new Vector2(-10f,0);
    }

}
private void OnTriggerEnter2D(Collider2D collider)
{
    Debug.Log(collider.name);
    if (collider.name == "smallpipe")
    {
        Application.Quit();
        UnityEditor.EditorApplication.isPlaying = false;
    }

}

}

this is the code basicly

You can see it spawns the bullet

but not where the player is at

only the middle

and i want to change that

any ideas

[languid spire]

I suggest you read the Instantiate documentation and look at all of the method overrides

Hello all, I am placing my character on a moving platform but I am getting two issues.
1: The character isn't sticking on the second moving platform.
2: There character mesh gives off weird stretching when it stands on the moving platform as you can see above.
I have been at this issue for nearly 2 days now, any suggestions are appreciated.

[rich adder]

2 the stretching is probably if you parent this to platform and plaform is resized

1. is probably you not properly un-parenting and re-parent to second platform ?
   (just assumptions based only what you give so far, show the code / setup)

[languid spire]

you need the following setup
Empty GameObject
-- Platform
-- Player

[onyx vortex]

Here is the platform code im using its pretty simple

If I want to make a question about the asset submission process, which channel should I use?

[rocky canyon]

good question..

their guidelines and documentation is pretty good

[languid spire]

there is no special channel so #💻┃unity-talk

[onyx vortex]

Hmm pretty sure, I am using the platform as the parent of the player~

[onyx vortex]

Oh yeah, that's one part figured out

[languid spire]

yes, dont do that

[onyx vortex]

Isn't this the only way to keep the player on top of the moving platform?

[languid spire]

no because the platform and player are children of the empty so when you move the empty they both move

[onyx vortex]

Its starting to make sense, a moving/deformed platformed will deform the player set as a child as well, giving weird results

[languid spire]

any object which is scaled will pass that scale to their children

[onyx vortex]

I see, well what about the script? It only works on the first platform but the player will slide like ice on the second one, even though the script is on the other one as well~

[onyx vortex]

this one

[spare mountain]

is the player getting parented on the second platform?

[languid spire]

ok, what do your debugs tell you?

[onyx vortex]

This is jumping onto the moving platform then jumping back to the normal one

This is jumping onto the moving platform then jumping to another moving platform (Player doesn't stick to the second moving platform for whatever reason) ¯_(ツ)_/¯

[languid spire]

then your platform setup is probably incorrect

[onyx vortex]

Perhaps, I have multiple collisions and rigid bodies on the Jumping character, might that cause this problem or its def the platforms?

[languid spire]

I would say it's the platform. put a debug outside of the if to see if the code is being called at all

[onyx vortex]

I think I got it, there are multiple collisions working against each other lol

I feel so stupid

[rocky canyon]

cant get smart w/o feeling stupid first 😉

glad u fixed it.. platforms are always a Bich

[stuck palm]

how can i remove a gameobject from a parent in code?

[rich adder]

Destroy(transform.GetChild(indexHere).gameObject)

you don't have a reference?

[stuck palm]

sorry i mean like

[stuck palm]

how can i change it so an object has no parent is what i meant sorry

[rich adder]

.SetParent(null)

[stuck palm]

okay

thanks

is that on transform or gameobject

[rich adder]

yes transform

[stuck palm]

cool

thank you 😄

Yo guys, call me crazy but what the hell is a constructor? Why do we need this guy? Is it a class? Is it a function? Why does it have to have the same name as the class? This is driving me insane!

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/constructors

[rich adder]

also constructors do not apply for Monobehaviour

[amber veldt]

Why is that??

[rich adder]

because Unity creates them internally

[amber veldt]

Why hides things from me?

[rich adder]

huh?

[amber veldt]

I'm having so much trouble man

Learning C# first then trying out Unity Logic is driving me loco

Thank you though, I'll check out the documentation

[rich adder]

yes there are differences between unity objects and regular c# objects, but in the end they all are objects

[amber veldt]

This is what confuse me the most, the fact that MonoBehaviour is an "autoconstructor"

When in C# I need to define the constructor

[rich adder]

MonoBehaviour is part of a bigger system

[swift crag]

Because a MonoBehaviour must be attached to a GameObject.

You are forbidden from creating a "naked" MonoBehaviour that isn't part of one

It would be bogus to do Component oopsie = new MyCoolComponent();

[swift crag]

You can define a constructor for a MonoBehaviour -- but it will execute before Unity applies serialized properties

[rich adder]

GameObject for example has a constructor

https://docs.unity3d.com/ScriptReference/GameObject-ctor.html

[swift crag]

public class Whatever : MonoBehaviour {
  public int x = 123;

  public Whatever() {
    Debug.Log("Value: " + x);
  }
}

This will log Value: 123, even for scene objects / instantiated prefabs that have a different value saved for the field

This is why you have Awake: it runs immediately after Unity creates the component and restores the serialized properties into it

(assuming its game object is active, at least)

[swift crag]

Unity has less power over your code than most people think.

consider this example:

public class DestroyMe : MonoBehaviour {
  public int val = 100;
}

public class Destroyer : MonoBehaviour {
  public DestroyMe target;

  void Awake() {
    Destroy(target);
  }

  void Update() {
    target.val += 1; // completely fine
    target.transform.position = Vector3.zero; // throws an error
  }
}

Destroying a Unity Object just tells Unity that it should go away from the game world. You are no longer allowed to use things Unity provides you (like the transform property), but everything else is fair game.

[rancid zenith]

am i a ding dong orrrrr, its saying PlayerLook aint a thing

[rocky canyon]

ur referencing a class called PlayerLook..
unless you have a script called PlayerLook.cs

it show an error

[paper peak]

public string[] lines;
```What does [] at the end of string word do

I tried looking on google but i dont know how to phrase it correctly

[rich adder]

array

[rocky canyon]

theres probably more to the tutorial or something you've missed @rancid zenith

[paper peak]

Nice thanks

[rancid zenith]

i legit know nothing, i just started, im using it the same way im using playerinput & playermotor

[rancid zenith]

possibly

[rich adder]

consider !learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[rocky canyon]

ya, thats what it is.. ur project just doesn't have a class called PLayerLook yet..

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

for further reading

[rocky canyon]

once you make one.. that error will go away

[rancid zenith]

alr lemme rewatch the past couple mins of this video

[rocky canyon]

care to share the video? ill skim it

[rancid zenith]

https://www.youtube.com/watch?v=rJqP5EesxLk&list=PLGUw8UNswJEOv8c5ZcoHarbON6mIEUFBC&ab_channel=NattyGameDev

[rocky canyon]

he creates it around here..

so just keep doing the tutorial.. and it'll work out.. not sure why he wouldn't create the script before trying to access it in another script

or perhaps he does..

[rancid zenith]

got it, yeah i missed that part up top, thanks!!

thats what i missed

[rocky canyon]

important part.. thats what defines the name of the class

[rancid zenith]

noted

[amber veldt]

Going back to the constructor thingy, there is this stuff called "Primary constructor" where you can put parameters to the class no?

It's a preview feature nah? sorry I'm a noob

https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/tutorials/primary-constructors

[swift crag]

Primary constructors are introduced in C#12

Unity is on C#9

[rocky canyon]

future man!

[amber veldt]

Got it, it's not confusing enough

plz end me boyz

[swift crag]

A primary constructor is just used to reduce the amount you have to write.

[amber veldt]

yeah I figured

But man the "instance" thing is my demon

everytime I see the "new" keyword, I have a panic attack

[rocky canyon]

simple, an instance is just a creation of a thing..

[swift crag]

take a chill pill and go follow some Unity tutorialsl

[amber veldt]

I'm around 1 year and a half of Unity tutorial

I need courses

So much stuff badly explained or plain wrong, now I only do official doc lol

But this is where the real journey start I guess hehe

[rocky canyon]

i learned with tutorials..and yea lot of stuff can be wrong.. but thats when u learn to fact check.. or get a 2nd opinion..

good skill to have in general

[storm pine]

Never try c++ then hahahah, this is the real hell

[amber veldt]

Yeah I'll stay away from this devil's creation

[paper peak]

Is it possible to add an entire string array to an already existing string array?

[polar acorn]

Arrays cannot be resized after creation.

[rocky canyon]

you shouldn't add to arrays

use Lists<> instead

[strong wren]

    public GameObject Coin;
    [SerializeField] float RespawnTimer;
    [SerializeField] bool isCoinGone = false;
    private void OnCollisionEnter2D(Collision2D collision)
    {
        Coin.SetActive(false);
        SS.Score++;
        SS.HealthVal++;
        isCoinGone = true;
    }

    private void Update()
    {
        if (isCoinGone == true)
        {
            RespawnTimer -= Time.deltaTime;
            Respawn();
        }
    }

    public void Respawn()
    {
        if (RespawnTimer <= 0)
        {
            Coin.SetActive(true);
        }
    }``` why is the respawn void thing not working?

wait leme make it so only the important stuff shows up

[rocky canyon]

it should work.. after isCoinGone gets changed to true

[strong wren]

it doesnt tho

[rocky canyon]

are u sure it doesn't get called? or rather Respawn Timer conditional isn't true

    public void Respawn()
    {
        Debug.Log("RespawnFunctionCalled");
        if (RespawnTimer <= 0)
        {
            Coin.SetActive(true);
        }
    }```

try debugging

[strong wren]

i put a log in the if isCoinGone statement

and ive noticed that its always on

theres a bug

if i turn it on manually the timer goes down but if it turns on from the collision it doesnt start

so the code should work?

like the code isnt the issue?

[rocky canyon]

use debugs and find out.. put them everyhwere so u can trace whats happening

[strong wren]

yeah i found alr an issue thats kinda wierd

but idk how to fix

[rocky canyon]

possibly ur collision isn't working correctly

[storm pine]

On Respawn I think you should reset your RespawnTimer

[rocky canyon]

^ thats 1 thing i noticed as well..

[strong wren]

so if RespawnTimer = 1 RespawnTimer Return;?

[storm pine]

Your RespawnTimer just go down and down but it is never reset

[rocky canyon]

public void Respawn()
{
    if (RespawnTimer <= 0)
    {
        Coin.SetActive(true);
        Debug.Log("Coin respawned.");
        
        // Reset the RespawnTimer
        RespawnTimer = initialRespawnTimerValue;
        Debug.Log("RespawnTimer reset.");
    }
}```

[strong wren]

as you can see all coins are present, the isCoinsGone bool is set to false yet the Debug.log is happending

[rocky canyon]

ya, after that first respawn.. ur timer is already lower than the threshold..

gotta reset it for it to be useful

[storm pine]

That's it, the condition will be always true if you do t reset the timer

[strong wren]

so if i have a variable and i put initial then the variable name it will reset the variable to the set number?

sorry im still learning the inital thing is new to me

[rocky canyon]

ya, at the start of the script u should cache what ur starting value is..

and then once u trigger the respawn reset the timer back to what it started as

[polar acorn]

Add this log in Update:

Debug.Log$"{gameObject.name}'s IsCoinGone = {isCoinGone}, Respawn Timer = {RespawnTimer} Coin = {Coin.name}");

[rocky canyon]

i usually count upwards.. that way i dont need an extra variable..

[strong wren]

oh this is not what i tought

[rocky canyon]

i just reset the timer to 0..

[strong wren]

so in my case i just do RespawnTimer = 3;

[rocky canyon]

if 3 is the value u want..

[strong wren]

i tought if i put initial it would like reset the value of the variable to the value i gave it by default

[rocky canyon]

hardcoding like that is frowned upon tho..

not unless u tell it to

[strong wren]

theres a tiny issue tho

my float is Serialized cause i have multiple and i wish for them to respawn well at diff times but thats kinda hard to do so i gave each coin a diff value

[rocky canyon]

digi's debug is a good choice imo shows all ur data in 1 string/sentence

[rocky canyon]

nothing wrong with that.. b/c each coin is it's own instance.. (version)

so u can use different values if u wish..

and thats y i said to cache the value..

u shoulnd't need to hardcode a value

[strong wren]

yeah but how do i reset it the to preset value?

[rocky canyon]

[SerializeField] float initialRespawnTimer;
float RespawnTimer;```

[strong wren]

if i do RespawnTimer = 3; then every coin will respawn every 3 seconds

wait im kinda stupid

nvm

[rocky canyon]

 RespawnTimer = initialRespawnTimer;```

private void Start()
{
    // Store the initial respawn time when the coin is instantiated
    RespawnTimer = initialRespawnTimer;
}```

[strong wren]

bro, how fast can you type?

[rocky canyon]

b/c i already have the script in a notepad

copy and pasting

thats y we urge people to post code.. instead of screenshots 😄

[strong wren]

no but i tough if i do do RespawnTimer = 3; then they all would respawn at the same time lol, that would only happen if all coins were picked up at the same time

[rocky canyon]

#💻┃code-beginner message

you can set ur initial value for each coin however u want..
the private variable cache's whatever you use

soo if u use a coin with a 4 it'll reset the timer to 4.. if u use one with 3. itll reset to 3

[strong wren]

    public GameObject Coin;
    [SerializeField] float RespawnTimer;
    [SerializeField] bool isCoinGone = false;
    private void OnCollisionEnter2D(Collision2D collision)
    {
        Coin.SetActive(false);
        SS.Score++;
        SS.HealthVal++;
        isCoinGone = true;
    }

    private void Update()
    {
        if (isCoinGone == true)
        {
            Debug.Log("You picked up a coin");
            RespawnTimer -= Time.deltaTime;
            Respawn();
        }
    }

    public void Respawn()
    {
        if (RespawnTimer <= 0)
        {
            Coin.SetActive(true);
            RespawnTimer = 3;
        }
    }```

this is the whole code

[rocky canyon]

because it just caches the value in start

[storm pine]

Each coin has her own timer, they don't share the variable

[rocky canyon]

^

[strong wren]

nah its fine

[strong wren]

yep thats why i serilized the Variable

sorry i forgot

[strong wren]

so this code should work?

[rocky canyon]

it'll only work if ur Timer is set to 3

any other value wont

[strong wren]

uhj

i think i found an issue

[storm pine]

It should, but is better to don't use magic numbers on your code like the 3, is better how spawn says

[rocky canyon]

magic numbers suck

[strong wren]

what are magic numbers?

[rocky canyon]

hardcoded values..

[strong wren]

like values set in the code?

like int Money 10;

[rocky canyon]

myCar.color = blue; vs

and then u can set desiredColor however u want in the inspector ```

the first one would be a magic number / color..

[strong wren]

uhm so i did smth and now smth else happened

[storm pine]

Yep, you can use direct values to initialize a variable, but no far from there

[strong wren]

everytime i ran the game this if (isCoinGone == true) { Debug.Log("You picked up a coin"); RespawnTimer -= Time.deltaTime; Respawn(); } would always go on now i turned smth off and it doenst spas out anymore

the isCoinGone bool was turned on in the inspector

which is wierd to give me an error since i made it so the bool is false by default

hm wierd

the if statement isnt working

this is interesting

if i start the game and i check the isCoinGone bool on in the inspector the code works

but if i pick up the coin which still turns on the bool it doenst

[storm pine]

You should also write the statement like if(isCoinGone) since is a Boolean itself

[rancid zenith]

my game feels like its running in like 30fps, its very choppy when i move, i.e: i can see the cubes skip frames when I move

[rocky canyon]

public class TimerScript : MonoBehaviour
{
    [SerializeField] private float startingTimer = 10f;
    private float currentTimer;

    private void Start()
    {
        currentTimer = startingTimer;
    }

    private void Update()
    {
        currentTimer -= Time.deltaTime;

        if (currentTimer <= 0)
        {
            currentTimer = startingTimer;
        }
    }
}``` here is a timer that i could use for different objects all having different values to count to... in the start method we just cache w/e we have set in teh inspector

```cs
using UnityEngine;

public class TimerScript : MonoBehaviour
{
    private float currentTimer = 10f;

    private void Start()
    {
        
    }

    private void Update()
    {
        currentTimer -= Time.deltaTime;

        if (currentTimer <= 0)
        {
            currentTimer = 10f;
        }
    }
}``` this version uses a hardcoded value... it can only ever work if our value is 10

[strong wren]

what does boolean mean?

[rocky canyon]

true or false... (on or off) (0 or 1)
bool

[strong wren]

but if i write if(isCoinGone) how would the code know to check if it should only run if the bool is TRUE

[strong wren]

oh

[storm pine]

The type of your variable, like int (integer), float, bool (boolean)...

[rocky canyon]

u already using it..

the condition returns true or false

[strong wren]

so just remove the == true?

[storm pine]

You can see the FPS if you press stats once you play. Start from there to see if there is a problem of optimization

[rancid zenith]

k lemme check the fps

[strong wren]

well nothing really changed

what if i move the if statemnt into the OncollisionEnter Void?

[rocky canyon]

😈 like my FPS counter?

[strong wren]

that did smth

[rancid zenith]

well im getting like 600fps, but it looks fuzzy when im moving for some reason

[strong token]

Don't set timers directly to to their start value if you keep them running like that, since u would accumulate some difference over time. Instead add it to the timer, then you will have more constant intervals.

[rancid zenith]

the edges become a little fuzzy and less defined

[rocky canyon]

ohh true, ive heard this before but i always forget about it

i use coroutines more often than not myself

[valid roost]

any idea why this occurs

[strong wren]

i so i put the if statement into the oncollisionEnter method and it fixed smth

now it works but not rlly

[rocky canyon]

theres a gameobject in ur scene that had a script on it.. that got deleted or renamed..

[strong wren]

if i pick up a coin it tells me that and it also only goes off once

[storm pine]

Some object has a component (script) that you have deleted

[strong wren]

but the RespawnTimer only goes down by 00.2

[valid roost]

its whenever i add a script

[strong wren]

its cause it only happends once

[valid roost]

it occurs

[strong wren]

if i maybe add another if statement then i can make it so it goes down

what if i make it so if the respawntimer is smaller then 3 it should make it even smaller

[valid roost]

😭

[storm pine]

RIP

[rocky canyon]

it gone..

[valid roost]

oh shit

i didnt see this

thx

[rocky canyon]

remove that

[valid roost]

thx

[storm pine]

To ensure, shut down your pc and change the hard disk, it doesn't look ok

[valid roost]

what

[rocky canyon]

idk lol

[storm pine]

Just joking, I thought the file of your script was corrupted by a bad hard disk

[valid roost]

i still

have that error

although there is no script

[strong wren]

i think theres an issue with my update method

[paper peak]

I have a public array(X1) in a script(Y1) and i have another array(X2) in another script(Y2),
Is there someway i can replace array X1 with array X2 while using script Y2?

Theyre both string arrays

[storm pine]

You want to use the same one so both want to modify the same array or just a copy of the array?

[west sonnet]

What's the best way to get an object to ignore collisions with another specific object, but collide with everything else?

[storm pine]

Use the tag of the objects

[west sonnet]

How?

[paper peak]

Array X1 is just there to be modified, its empty most of the time. I want to replace the contents of array X1 with the contents of array X2

[storm pine]

Set a tag on you object and in the method OnTriggerEnter2D(Collider2D other) just add a simple condition like: if(other.CompareTag("Player")), so it will only work if the object that start the trigger is the type of player

[strong wren]

    public GameObject Coin;
    [SerializeField] float RespawnTimer;
    [SerializeField] bool isCoinGone = false;
    [SerializeField] bool TimeStart = false;
    private void OnCollisionEnter2D(Collision2D collision)
    {
        Coin.SetActive(false);
        SS.Score++;
        SS.HealthVal++;
        isCoinGone = true;
        if (isCoinGone)
        {
            Debug.Log("You picked up a coin");
            TimeStart = true;
        }
    }

    public void Update()
    {
        if (TimeStart)
        {
            RespawnTimer -= Time.deltaTime;
            Debug.Log(RespawnTimer);

            if (RespawnTimer <= 0)
            {
                Respawn();
            }
        }
    }
    public void Respawn()
    {
        Coin.SetActive(true);
        isCoinGone = false;
        TimeStart = false;
        RespawnTimer = 3;   
    }``` why is this code not working 😩

[scarlet skiff]

so i started making my game work for multiplayer, but then it kinda messed up the single player, this prob related to the player or whatever having netcode properties while the scene doesnt have an object woth a network manager, but i dont know exactly what to od here, here is the error:

what is liek the best way to make a scene not think of the multiplayer stuff?

[storm pine]

You should be able to change the reference as in this little example: https://hatebin.com/rvcyivyyej

[storm pine]

First of all, your condition on the OnCollisionEnter2D will be always true because you set directly to true on the line before, so this doesn't have too much sense

[strong wren]

yeah i put the if statement there because if i put it in update it breaks

idk why

yeah now the debug isnt even working

 public GameObject Coin;
 [SerializeField] float RespawnTimer;
 [SerializeField] bool isCoinGone = false;
 private void OnCollisionEnter2D(Collision2D collision)
 {
     Coin.SetActive(false);
     SS.Score++;
     SS.HealthVal++;
     isCoinGone = true;
 }

 public void Update()
 {
     if (isCoinGone == true)
     {
         RespawnTimer -= Time.deltaTime;
         Debug.Log("You picked up a coin");
         Respawn();
     }
 }

 public void Respawn()
 {
     if (RespawnTimer <= 0)
     {
         Coin.SetActive(true);
         isCoinGone = false; 
         RespawnTimer = 3;
     }
 }``` this is the original code

and it still doenst work which makes no sense

[storm pine]

Your console show any error? Maybe you think the error is in this code and something is just breaking the game and make it stop working

[strong wren]

if i pick up the coin then the bool should be set to true and every frame it checks if the bool is true

[strong wren]

no error

[strong wren]

it doesnt break the whole code

[strong wren]

and if it is then the if statement should go off and in the if statement it always checks on the respawn method which has a if statement that only works till the Respawn timer is smaller or reaches 0

[storm pine]

private void OnCollisionEnter2D(Collision2D collision)
{
if(!iscoinGone){
Coin.SetActive(false);
SS.Score++;
SS.HealthVal++;
isCoinGone = true;
}
}
try changing this method, this way it will just iterate once

[strong wren]

then it should spawn in the coin then set the isCoinGone bool to false shutting down the if statement in the update method

[strong wren]

but then wont the code only work if the isCoinGone bool is true? which by default is off and gets turned on in that method/

[storm pine]

I add the ! at the beggining, that just make the opposite

[strong wren]

oh

[storm pine]

It's translated like a not

[strong wren]

nothing changed

wait i found smth interesting

[storm pine]

Try changing like this:
public void Update()
{
if (isCoinGone)
{
RespawnTimer -= Time.deltaTime;
if (RespawnTimer <= 0)
{
Respawn();
}
}
}

public void Respawn()
{
Coin.SetActive(true);
isCoinGone = false;
RespawnTimer = 3; // Reset timer
}

So it's the update the one that checks if the timer is less than 0

[strong wren]

i tried that too

but i found smth interesting

{
    if (isCoinGone)
    {
        Debug.Log("Coin isnt there");
    }
    else
    {
        Debug.Log("Coin is there");
    }
}```

i added this to my

update method right

well it works as intented

but it only says Coin Isnt There if i pick up ALL the coins

[storm pine]

Your code is not that complex, something may be wrong in other part

[strong wren]

yeah but shouldnt this be smth we should look at?

the Debug.Log("Coin isnt there"); only runs if i pick up ALL the coins

[rocky canyon]

it may be there but being pushed out of view by ur debugs..

shuld collapse ur debugs so duplicates just get a number added to the side of it

[strong wren]

i do have that

doesnmt everyone?

[storm pine]

add private to your variables
[SerializeField] private float RespawnTimer;
[SerializeField] private bool isCoinGone = false;

[rocky canyon]

lol.. somepeople dont

[rocky canyon]

just checkin

[strong wren]

🤮

[rocky canyon]

can't remember if its default setting or not

[strong wren]

but isnt SearlizeField just Private? but it shows on the inspector?

[strong wren]

its not

[rocky canyon]

a private variable w/o serialized field can't been seen in the inspector

[strong wren]

so i cant see my variables in the inpector now?

[rocky canyon]

by using serialized field on a private variable.. u keep it so other scripts still cant access it. but its visible in the inspector (as a public field would be)

[strong wren]

oh ok

still didnt fix anything btw

[storm pine]

Nop, it doesn't, you have to specify

[rocky canyon]

i think its just a tip more than a fix..

learning the right way to do things..

[strong wren]

dude why is it not working 😩

its such a simple code

[storm pine]

Yep, as the parse of the variable. Use the same for all your variables, it's better if you start with lowercase, so you can easily difference the classes from the instance of the objects

[rocky canyon]

i dont even understand the issue tbf

[strong wren]

    {
        if (isCoinGone)
        {
            Debug.Log("No more " + Coin);
            RespawnTimer -= Time.deltaTime;
            Respawn();
        }
    }```

this isnt running

it should run when the isCoinGone bool is set to true

[rocky canyon]

true

[strong wren]

which gets set to true if i collide with a specified thing

[rocky canyon]

show that part

[strong wren]

   {
           Coin.SetActive(false);
           SS.Score++;
           SS.HealthVal++;
           isCoinGone = true;
   }

this works tho

when i collide with the specified game object the isCoinGone gets checked

[rocky canyon]

Coin.SetActive(false); if the coin gets set to InActive.. the update loop wont run anymore

[strong wren]

so the code stops with it too?

[rocky canyon]

yes..

if u disable the object.. the update loop wont function anymore

[strong wren]

how.... do fix it tho?

where should i play the Coin.SetActive(false);?

i cant place it in update can i?

[rocky canyon]

after u do all the stuff u want it to do

u should probably use a Coroutine..

[strong wren]

😷

[rocky canyon]

that way u can delay the setactive part.. until the rest of hte code finishes

[strong wren]

idk what that is

[rocky canyon]

lets back up..

what is it that you want to happen?

and also !code share ur code in a paste-bin link so i can see the entire thing

when i collide with the Coin i want it to dissapear then i want to get 1+ in the score and an extra second to live (u get 5 at the start) then i want the coin to respawn after 3 seconds

pretty simple

[rocky canyon]

okay.. cool yea, that does sound pretty simple..

now share ur code in a paste link

[strong wren]

yeah i wrote the code myself with no issues so ofc its simple

https://hastebin.com/share/cafaxalelo.csharp

here

[tepid pike]

can someone walk me threw on how to export your game as a apk

[strong wren]

its easy?

you go into build settings and switch the platform to andriod

tbh i should also ask why i couldnt export my game i had some issues with gardle and i couldnt export it

which sucks but maybe i can get help here

[tepid pike]

can i share my screen

to you

[strong wren]

sure/

[tepid pike]

ok i made a call

[storm pine]

You can use the same code, but don't add it to the object that it's your coin. You can have a parent (we could call it Coincollider for example) that will have the component Collect and the Collider and a child object inside of it that will just have the sprite of the coin

[strong wren]

oh

[rocky canyon]

alright check this out

https://www.spawncampgames.com/paste/?serve=code_602

the graphics are seperate from the coin.. that way i can disable the gameobject..
you could use a single object. and just disable the meshrenderer instead.. meshRenderer.enabled = false;

[strong wren]

so i make an empty gameobject with the collider of the coin and when that collides with the player it turns off the coin but not the collider

wont that make it so you can always colide with it?

[rocky canyon]

but what happens is i enter the trigger:

• the coroutine starts
• it disables the graphics
• and disables the collider (so now we can't collide with it anymore)
• it then waits 3 seconds
• and re-enables everything

[rocky canyon]

i used a child for the graphics... so i could just disable the graphics (this keeps the script running because i dont disable the main gameobject with teh script)

orr.. u could reference the Mesh Renderer.. / sprite renderer/ or w/e and disable that instead

but i disable the graphics and the collider <-- thats the main point.. b/c we want the gameobject to still be active and run the Update()

[paper peak]

It worked, thanks man

[rocky canyon]

u could also

• Coin Object
• Graphics + Collider <-- just disable this gameobject

to disable both the graphics and the collider at the same time

[strong wren]

oh wait

i can do that

[rocky canyon]

many ways to do it. but the idea is to keep the Coin (Script) running

just disable the collider intead

and i Use a coroutine.. b/c its better than a timer.. (imo)

[strong wren]

alr

[stuck palm]

how can i repeat a block of code a set amount of times? i know theres a for loop, but what if i want a delay between loops?

[strong wren]

what if i make a gameobject put the code there?

it should still work right?

if it collides with the GameObject specified in the inspector which is coin 1 it should turn it off but its not the gameobject running the code

[rocky canyon]

Collision events have to be run from a script on teh same gameobject as the collider

[strong wren]

oh

[rocky canyon]

u can't put the script else-where and expect it to log collision events

from a different collider

the reason i referenced the collider is just so i can disable it.

[strong wren]

how can i turn the collision off on a gameobject?

[rocky canyon]

now u can disable other colliders and things from different scripts.. but the Collision events dont work that way

[rocky canyon]

u either set the collider to isTrigger or on the collider itself u can chose a layer to exclude

and put ur objects on that layer that u want to ignore

u can also do it globally from here

u can uncheck certain layers.. soo entire layers ignore each other

[strong wren]

huh?

but cant i dissable the collider of the empty GameObject Thru Code?

float SpeedX, SpeedY;
Rigidbody2D RB2D;
public SpriteRenderer SR;
void Start()
{
    RB2D = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update()
{
    SpeedX = Input.GetAxisRaw("Horizontal") * MovSpeed;
    SpeedY = Input.GetAxisRaw("Vertical") * MovSpeed;
    RB2D.velocity = new Vector2(SpeedX, SpeedY);
    if (RB2D.velocity.x > 0f)
    {
        SR.flipX = true;
    }
    else if (RB2D .velocity.x < 0f)
    {
        SR.flipX= false;
    }
}``` as u can see here im turning the FlipX thing on and off at will

[rocky canyon]

you can disable any collider u have a reference to..

[storm pine]

If it will always be the same delay you can do with a Coroutine where at the end of the loop just do a yield return new WaitForSeconds(x);

[rocky canyon]

a collider is just like any other component

component.enabled = true/false;

[strong wren]

[SerializeField] CircleCollider2D CC; this is how il refrence it but how do i call it?

[rocky canyon]

CC.enabled = false;

[strong wren]

oh

i tought smth like CC.Collider = false

wait im so stupid it makes more sense if u say it idk

[rocky canyon]

no.. ur referencing a collider..

[strong wren]

yep i just realized

[rocky canyon]

aCollider.aCollider doesnt make sense

[strong wren]

yeah i just realized

[storm pine]

CC is the collider itself not the game objects that contains it

[strong wren]

affermative i just realized

[rocky canyon]

^ if u referened a gameobject with CC
then it would be
CC.GetComponent<CircleCollider2D>().enabled = false;

which would get a CircleCollider2D from the gameobject thats called CC

[strong wren]

ok

omg it works

dude @rocky canyon me and 4 other guys have been stuck on this issue for 8 hours

[rocky canyon]

glad i could help

[strong wren]

im not kidding i started making this feature at like 15:00 now its 00:27

ive asked in brackeys in the gamejam server

[rocky canyon]

😅

[strong wren]

and it was such a simple thing 😭

[rocky canyon]

ya, i figured once i wrote a script and showed a video.. it'd kinda start to make sense

heres a tip to keep in mind..

keep ur graphics and ur logic seperate

always!

• Root Gameobject
• Graphics

[strong wren]

oh

[rocky canyon]

it'll save soo much trouble in the long run

if u want to do stuff w/ ur graphics u shouldnt have to worry about ur scripts stop running

same w/ the colliders and whatnot..

its not always the case.. but its easier to know that ur script is running on its own gameobject

and physics and rotations go crazy when ur scales are different than 1:1:1

so thats another reason..
ur root object should always be scaled to 1.. and that way ur graphics can be resized as a child object and it wont affect the way physics interact w/ ur object

like the example i sent earlier.. my coin is actually a squished sphere..

[stuck palm]

thank you

[rocky canyon]

but i squish the child object.. so the Coin object is still scaled to 1:1:1

[minor musk]

Quick question, is there a Physics.SphereCast equivalent for Physics2D? All I'm trying to do is to check if there's a collider in the specified area but they all require to provide a Collider2D list, or RaycastHit2D list, or they return a RaycastHit2D/Collider2D result, I don't know how to check if there's an object or not in the specified area

[eternal needle]

You could just use the return value and check for null. The ones that return Collider2D will return null if nothing hit

[minor musk]

I have to filter or check if there's more than one collider 'cause it detects the 2d capsule collider as well, I have the controller as a children

so far everything I've tried always returns true so I'm trying to understand what's happening

coming from the 3D side this is quite weird for me x)

[eternal needle]

I believe in 2d, casts will hit the object it started inside of. Maybe do it based on layer, or just use the list and check if the length is greater than 1

[blazing plank]

Does anyone know how to input small float values in the Unity inspector?
I can't fade the image out smoothly because small steps are visible during the fade

0.001 seems to be fine, but steps of 0.0001 aren't visible

[slender nymph]

show the code you are using to actually fade it out. because it seems like you are hard coding the steps rather than gradually fading over time

[quaint mica]

if (heartcounter == 4 && SceneManager.GetActiveScene().name == "Level2")
{
    SceneManager.LoadScene("Level3");
}

This code works sometimes but sometimes the other scene doesn't load

Does anyone know why that happens

[slender nymph]

well for starters, why do you need to compare the active scene's name instead of just incrementing the current scene index and loading the next scene with that? also have you done any debugging to ensure this code is actually running and that your conditions are what you expect them to be?

[quaint mica]

Would it make a difference if I used an index vs using the scene name

Is it for performance?

[slender nymph]

no, it would reduce the amount of very similar code. because i'm just gonna go ahead and assume you have a very similar check for moving from Level1 to Level2

and it would remove a mostly useless check

[spare mountain]

this is the fade out code?

[slender nymph]

that is someone entirely different

[spare mountain]

OH

my bad

sorry scar

[quaint mica]

I have debugged it and it works but sometimes the scene doesnt load

[slender nymph]

have you confirmed that code is running at the time you expect the scene to load but it doesn't?

[quaint mica]

Yes it usually only doesnt load when its built. It works fine most of the time in the game view

[slender nymph]

and have you done any debugging in the build to ensure the code is running and your conditions are what you expect them to be?

you've also not shown the context for this code, so this is really the only advice i can provide

[quaint mica]

How do i debug in a build

[slender nymph]

build as a development build and attach the debugger. you can use breakpoints and tracepoints to see what your code is actually doing

https://unity.huh.how/debugging/debugger

[quaint mica]

Ok thanks i will try that out

[blazing plank]

The code is a bit complicated, but here it is:

float opacitySpeed = CalculateOpacitySpeed(Mathf.Abs(OVRInput.Get(OVRInput.Axis2D.PrimaryThumbstick, ovrGrabber.GetM_Controller()).y));

//Checking for controller input, that's just the example for the downMovement of the stick:
if (downMovement)
                {
                    currentColor.a = (Mathf.Max(currentColor.a - (opacitySpeed * Time.deltaTime * 0.8f), 0f));
                    
                    controllerItemCollection.opacityDownIcon.transform.localScale = Vector3.Lerp(controllerItemCollection.opacityDownIcon.transform.localScale, downIconScale /*the target*/, Time.deltaTime / scaleLerpTime); //TODO: put the code from the bottom from scaling inhere, this seems more responsive
                }

float CalculateOpacitySpeed(float thumbstickPosition)
    {

        if (thumbstickPosition < activationAmount) return 0; // No scaling below 20%
        else if (thumbstickPosition >= activationAmount && thumbstickPosition <= 0.95f)
        
        {
            float normalizedPosition = (thumbstickPosition - activationAmount) / (0.95f - activationAmount); // Normalize position to range 0-1
            float speedFactor = normalizedPosition * normalizedPosition; // Apply quadratic curve for more noticeable speed change
            return minOpacitySpeed + (maxOpacitySpeed - minOpacitySpeed) * speedFactor;
        }
        else return maxOpacitySpeed; // Use maxSpeed above 80%
    }

The whole code is in the update method

[spare mountain]

put the 'cs' on the same line

[strong wren]

hi

[spare mountain]

```cs

not
```
cs

[strong wren]

i have this simple issue where i cant call a function from my other script

[spare mountain]

don't ask to ask

[blazing plank]

that's what i have done, it's weird

[strong wren]

i just said hi

[slender nymph]

yours is on the next line

[spare mountain]

fair enough
but your second statement definitely lacks information

[strong wren]

yep i was about to provide it

[spare mountain]

sorry, go ahead :)

[strong wren]

as you can see i am trying to call on my script SoundManager but it gives me an error, the thing is ive called ScoreSystem the same way and still no error

[blazing plank]

ah, fixed it

[strong wren]

it just says the namespace couldnt be found

[spare mountain]

show your soundmanager script

[strong wren]

using System.Collections.Generic;
using UnityEngine;

public class SoundManager : MonoBehaviour
{
    public AudioSource Shark;
    public AudioClip eat, die; 
}

simple code

[rocky canyon]

it says that cuz it assumes that u wouldnt try using a script that doesn't exist
so.. if it does exist.. its probably a simple mistake like u forgot to add the namespace
but most newbies.. the script is just missing

[strong wren]

very tiny

[spare mountain]

does this error happen when you try and run the game too?

[strong wren]

i didnt try to run the game im trying to add sounds

[spare mountain]

okay but will it let you run the game?

[strong wren]

and whilsts i was calling on the sound manager script it just gave me this error

[spare mountain]

does this error show up in the editor?

[strong wren]

no

[rocky canyon]

has this been saved?

[strong wren]

yes

[rocky canyon]

odd

[blazing plank]

by that i mean i fixed the formatting in discord

[rocky canyon]

y u have so many problems

[strong wren]

yeah

[strong wren]

ask my parents

[rocky canyon]

oof

[rocky canyon]

try going back into unity and letting it recompile

[strong wren]

ive been ther

but the error doenst show up in the console

[spare mountain]

then just ignore it or re set up your ide idk

[blazing plank]

By the way, I don't think there is a problem in the code, since it logs the values correctly. They gradually increase, but in very small intervals. Unity just seems to round them up for the opacity

[strong wren]

what

[spare mountain]

!ide

[eternal falcon]

💡 IDE Configuration

[strong wren]

oh yeah found the issue

[spare mountain]

if you try this again it might go away

[spare mountain]

what was it

[strong wren]

its set as a misc file

[spare mountain]

lol

[strong wren]

how... do i change it?

everything else is in asemble.C#

leme just reboot visual studio

yep there u go

[stuck palm]

if unity used doubles instead of floats, would that glitchy effect not happen when you get far away from the world?

[swift crag]

If the method returns Collider2D, you'll get null if nothing was hit.

If the method returns RaycastHit2D, the collider field will be null if nothing was hit.

If the method takes a list, it will return an integer that tells you how many things it hit.

[swift crag]

It would take much longer for it to happen, yes

Although, that glitching is caused by rendering

you'd have to be using doubles on the GPU

[stuck palm]

why does unity use floats again?

[swift crag]

because floats are smaller (4 bytes vs. 8 bytes), and float math is much faster

[stuck palm]

right

[swift crag]

it's the same reason that you use half-floats for machine learning

[stuck palm]

are there any engines that use doubles?

[swift crag]

dunno off the top of my head

Unity does have a Double4x4 matrix struct that you can use to do all of the usual transform math with doubles

I've experimented with using that for one of those "scale of the universe" visualizers

you know, where you zoom out from a cell to the size of the universe or whatever

everything stored its actual position as a Double4x4, which was then used to set its actual position, rotation, and scale

[stuck palm]

yeah

interesting

idk why i asked i was just curious lmao

thank you

[quick kelp]

hey
kinda need some help. Made my items persistent by attaching a dontdestroy on load script to them the items are children to the dontdestroy script
found this bug that i have no clue on how to fix for the time being where if i pick up one in the room it shows up in the slots but if i leave with said item come back to said room pick up another the 2nd item does not show up in the 2nd slot

[rocky canyon]

is float3 still a thing?

[quick kelp]

getting hastebin code now

https://hastebin.com/share/vuyenegila.csharp
the onitempickup from the inventory view selector

and the itemData stuff
https://hastebin.com/share/livezarika.csharp

[swift crag]

Yes. It's part of the Mathematics package

[cosmic dagger]

Doesn't shaders use it?

[rocky canyon]

i think so..

thats where im seeing it

wasn't sure if it was outdated

but it is indeed in the mathematics lib

float3 is more performant.. i think

im still reading on it

[rocky canyon]

are rooms different scenes?

[quick kelp]

yes

[small mantle]

@ashen niche What happened after you did it?

[ashen niche]

nothing rlly tbh, just made movement a bit smoother

[feral moss]

How do I have an object instantiated after the game starts running set a reference to an object that's existed since the game started running?

[small mantle]

Also, I saw you had been multiplying with Time.deltaTime. You don't need it if you think it is making the Movement stable for every system. Time.deltaTime is only needed in Update, not FixedUpdate as it already uses it at default.

[feral moss]

I have a grid whose tiles are prefab objects, and I'd like them to have a reference to the gridManager object that created them

[slender nymph]

that's not entirely correct. you still do need to multiply values by deltaTime when you need to increase something overtime at a specific rate of time

[small mantle]

Thank you for the corrections. I'll keep that in mind

[frozen steeple]

I'm creating the player controller and Im using a CharacterController to have the player walk around. The thing is, I want to have the player fly on a broom occasionally. Can I still use the CharacterController for that? or do I just disable it and enable a RigidBody?

[frosty hound]

You can use the CC still

[small mantle]

I don't really see an issue with the code that you sent, outside of the using Transform to move. Is there another place where you add movement?

[slender nymph]

moving via the transform is 100% the cause of their issue. doing so does not respect colliders so they are more easily able to penetrate into other colliders even with continuous collision detection

[twilit pilot]

you've likely omitted the code that actually causes this behaviour

I'd think most likely you're clearing the _slots list/array somewhere

[quick kelp]

yeah i honestly dont know why i only highlight the pickup part let me fetch the rest

https://hastebin.com/share/hexuniteni.csharp

here the whole inventory select

[twilit pilot]

is this on a DDOL GameObject?

[rocky canyon]

he mentioned his items are children of a DDOL i think

[quick kelp]

the menu no
the way it works is the player, misc controllers and inventory are children in a dontdestroy object

i do it this way cause the script has an object index

as to destroy duplicates

[feral moss]

//In Tile.cs used by the Tile prefab within the Tile class object
public GridManager grid;

//Class header in the script used by the GridManager object present in the scene
public class GridManager : MonoBehaviour

Why am I getting a type mismatch here?

[slender nymph]

are you trying to drag a scene object into an asset like a prefab? because that's not possible

[small mantle]

I am making a game where the Player can turn into two types of forms (outside of their default), a Gear Form or a Super Form. I am wondering how I should keep track of these two Groups. Should I use GameObject arrays or Lists. I ask because I won't have more than 10 forms for each Group. Which method would be more effective and easy to navigate for this concept?

[feral moss]

That's about what I'm trying to do. I would like the instantiated objects to be able communicate with the scene object after they're created

How do I do that in code?

[quick kelp]

if it helps this is how the ddol is laid out

[slender nymph]

https://unity.huh.how/references/prefabs-referencing-components

[feral moss]

Ah thank you

I'm also curious why Type mismatch is the error it gives me

Or why it lets me try to select a scene object for that field

[slender nymph]

why are you choosing between arrays and lists? they are practically the same, except that List can have things added and removed at runtime while the size of an array does not change without a new array being created

[twilit pilot]

I'm not totally sure I follow to be honest, but there's not a lot going on I'd say - you've got one list and it's clear there's a mismatch between what is contained in it and what you expect there to be. I'd add some debug lines to check what is actually in that list as you pick up an item, leave the room, re-enter the room, etc

[slender nymph]

it just uses the same menu for all unityengine.object assigned fields, including the ones in the scene. so for the ones in the scene you need to be able to select an in-scene object

[small mantle]

Well that makes things easy. I never use Lists so I was just checking if I was going to have technical debt in using GameObject Arrays. Thanks!

[slender nymph]

i mean your arrays should also not be GameObject type but rather the type of component you actually care about using

[quick kelp]

ok to explain before i got back and try with debug logs

if i start to play and pick up item A it shows up in the inventory slot not problem the problem arises when i leave the room to next scene and come back to pick up item B thats were the problem is im able to pick it up cause the object disappears as it pickup code tells it to do

its that item B upon pickup wont show up in the second slot

even tho i picked it up

and now that i think about it i might need to look at the pickup code

[twilit pilot]

to be clear I understand the problem, but I don't follow your explanation of which script is which

if InventorySelectController is not on a DDOL object, that is your problem

[quick kelp]

this is the inventory ui controller

[quick kelp]

this is the ItemData script

[twilit pilot]

if it is, then I'd add some debug logs to check what the status of that list is as you change rooms

[quick kelp]

ok pick up script works according to logs

so must be the ui controller

[twilit pilot]

yeah, sounds like a reasonable next step if the data structure is correct

[quick kelp]

yeah

its the ui controller

[quick kelp]

this snippet of code is the source of my trouble

pick up item before leaving room

debug log tells me a slot has been filled

leave room and come back and pick up test cube

debug log says nothing

only the first log of a slot being filled

[misty coral]

this is a location in the gameworld right? Im tryna lerp toward it but it seems my object just goes endlessly

[deft grail]

show the full line of code and surrounding code

this gives absolutely zero information

[misty coral]

err...

I dont necessarily need a direct answer to the problem

because its like 250 lines long

I just need to know what Im doing

(I dont)

[deft grail]

a lerp is not 250 lines long

[misty coral]

well its not just lerp

it handles a lot of other stuf

[deft grail]

and no one can help of saying
"this is my add force is it correct?"
transform.postion + 65f + other.position - 32.0005f

[deft grail]

show the line of code with lerp, and where is it placed, in Update? or how is it called

[misty coral]

I think the problem Im having is I have multiple areas where I call lerp, and Im finding out that stacking lerp calls doesnt work that great

[deft grail]

impossible for me to know the problem by just seeing a bit of maths

so i cant really help either

[misty coral]

I think Ill try a different solution

I dont rlly want you to have to read 250 lines of spagetti

[deft grail]

i wouldnt read 250 lines anyway 😂
just find the lerp and what i need

[misty coral]

Like you can see from the vid, I am lerping to a bunch of positions

I changed it now to a timer, but it still looks jank

[deft grail]

why not use an animation?

[misty coral]

Am compsci student and thought it would be fun to do it that way

because if I animate it its not a "coding project"

[deft grail]

well theres probably better ways than lerping anyway

[misty coral]

also isnt procedural better to be able to apply recoil patterns to a bunch of things? Instead of animating them individually

Like I can just change some numbers and have a different recoil strength for a dif gun

[deft grail]

this is the opposite of procedural im pretty sure

[misty coral]

huh

[deft grail]

but looking at your code there isnt even a lerp?

your using move towards

[misty coral]

I changed it

I was just messing around

[deft grail]

sooo, show the code we actually need to be looking at?

[misty coral]

(Im tryna figure out the difference)

[misty coral]

wym

just imagine the movetowards is a lerp and that is the code

[deft grail]

the current code, the one with the lerp, the one your trying to fix

[misty coral]

So the issue Im having is that because (as you can see from the video) I am lerping/movingtowards a bunch of different positions, and they dont work well with eachother

[deft grail]

ive never seen if(UnityEngine.Input.GetKey)
you import Unity for a reason so you can do just Input.GetKey

[misty coral]

Yea I had it like that and then VS kept flagging it

I am pretty sure it works either way

[deft grail]

i guess, just unnecessary and long for no reason

[misty coral]

you mean my entire code? LOL

But yeah I was thinking to fix the issue Im having I could have all the lerp/movetowards handled by one lerp call, and I use different methods to adjust where it lerps towards

that could work right?
