[obsidian parcel]

spikes is this one right

[rich adder]

youre supposed to put the white cursor on it and read the values on that frame

expand the arrows untill you see the cause of high ms/gc alloc

[obsidian parcel]

okay

[rich adder]

EditorLoop is the unity editor

[obsidian parcel]

i think i got it what is happening like if i select a cube(Spline Animate) while playing in editor it drop downs to 180 -200 but when i select something like fog it goes back to 600-800

is it because its debuging the value in inspector?

[rich adder]

what I would do to be sure is run a standalone profile

you would be able to see if the editor is just causing too much overhead

[wintry quarry]

sounds like the inspector for the spline being slow, but again, you;'d have to profile to know for sure

[obsidian parcel]

aight will surely look into it

[swift crag]

Yeah, inspectors can be very slow.

especially if they're all IMGUI-based and you have a gigantic pile of complex components

as I've experienced recently

[rich bluff]

yes editor eats performance

its a hungry beast

[swift crag]

nom nom

fullscreen the game view to get a better idea of performance

[rich adder]

esp when you have lots of gizmos xD

[rich bluff]

the more inspector has to draw the more ms you lose thats why its best to test in maximized game view, with release mode enabled

yes with gizmos disabled

ideally test in build

but release mode maximized is pretty close

[sharp wyvern]

not sure if it's been mentioned yet: remove all Debug.Log command before profiling- these can get SUPER slow.

[rich bluff]

right because those get sent to editor console which also hogs like crazy under spam

[queen adder]

what should i look at if i want to like have spells like in original Dragon Warrior? How to store how the magic and what it does?

like Heal, Heal All, Magic Blast thingy

[rich bluff]

never heard about that game, but common place to start is ScriptableObjects and Prefabs

[queen adder]

https://strategywiki.org/wiki/Dragon_Warrior/Spells

now i miss it

[queen adder]

yea, im thinking about SO approach but that would like need me to make many .cs files, for each spell

im quite allergic to making many files, idk why

[rich adder]

why would you need many files with SO ?

[verbal dome]

Because each SO needs to be in its own file

To get serialized properly

[sharp wyvern]

teehee, I dig that username! Not sure how thy do it in the game, but I'd suggest some kind of heiarchical structure- base class to store stuff common to all spells (mana cost, min level to cast, etc...) and derived class to implement each spell, which will probabably require an overriden function for "Cast" or "Effect"

[queen adder]

this the reason it have to be many file

[rich adder]

yeah but You only create 1 script for each no?

but can create many SO from 1 file

[sharp wyvern]

if you make em SO's, then I'm afraid so- unity requiriment

[rich bluff]

not necessary

[queen adder]

second approach im thinking is a SpellLibrary and reflection, but is quite nasty

[rich bluff]

you can have a single SO representing a generic spell, and in that SO you reference a type of spell behavior it will use

and dump all your spells in a massive .cs each as a separate class

or serialize an instance of those classes right in the SO with Odin, for example

[queen adder]

that too, then switch?

[rich bluff]

yes switch is the last option

there is also a visual spaghetti option

[queen adder]

i had a custom unityevent approach before, but it was painful to set up

[rich bluff]

you dont have Odin?

[queen adder]

    public void Satiety(Creature toHeal, int potency, Vector3 targetPos, Matter Target)
    {
        var activeSat = toHeal.GetComponent<Satiated>();
        var eaten = InventoryManager.LastItemUsed;

        if(!activeSat || activeSat.Duration * activeSat.Intensity < eaten.ItemData[0] * eaten.ItemData[1])
        {
            toHeal.gameObject.AddComponent<Satiated>().Inflict(eaten.ItemData[0], eaten.ItemData[1]);
        }
    }``` this will be registered to unityevent, but is so annoying if these parameters dont have what the spell need

no odin

[rich bluff]

you can use type reference but then no per instance parameters

[queen adder]

type reference?

hmm.. ig imma just go with simple, partial class holding an enum switch

[rich bluff]

yes you can relatively simply serialize types

https://github.com/pointcache/unity3d-safeTypeSerialization
ancient repo but the principle works

[queen adder]

nothing's ancient

[rich bluff]

same thing microsoft is doing in its libraries with TypeID attribute

[fallen lance]

does anybody familiar with this error

[rich bluff]

attach guid to any type with attribute, serialize that guid, and you will never lose a reference to that type

[queen adder]

is this repo like SerializeReference?

[rich bluff]

it is specifically a serialized Type

[queen adder]

lemme try the demo

[queen adder]

try asking in #📱┃mobile, better chances in there

I think it's incompatible in my unity

[thick mortar]

who can help me with a certain issue

[fossil drum]

Just ask your question, there are 20000 people online

[thick mortar]

follow me privately

[fossil drum]

No

[thick mortar]

come onnn its argent

[rich adder]

if its urgent you would spit the out the question instead

[rich bluff]

why Unity 2017????????

(joke)

[rich bluff]

not sure what can be incompatible, maybe it was made in 2018 and serialization fails

what is that file?

[swift crag]

ask your question .

consult #854851968446365696

[queen adder]

your SO instance

[rich bluff]

just create new one

[queen adder]

interesting

if I use this SO, it automatically makes a new instance of the Ammofreezing?

[rich bluff]

i dont know what it does

[queen adder]

u wrote it

[rich bluff]

the reference just will return you the type

use Activator.CreateInstance(referencedType)

[queen adder]

this can be accessed with ```cs
SO.ClassToSpawn.AmmoFreezing();

[rich bluff]

no

ClassToSpawn is Type

not an object

[sharp wyvern]

hunh? A System.Type IS an object

[queen adder]

so this SO kinda need a supporting field that accepts an Ammo object?

[rich bluff]

yes but its an object of type Type not of the end type that has method AmmoFreezing

[verbal dome]

It just allows you to serialize a System.Type

Right?

[rich bluff]

yes

[summer stump]

Guess it wasn't that argent

[queen adder]

this is the selling part, I see

[sharp wyvern]

var

[rich bluff]

class HealSpell : SpellBehavior
{
    public override void OnSpellCast() {
        // do healing
    }
}

class SpellSO : ScriptableObject
{
    public SerializedType spellType;
    public Spell GetNewBehaviorInstance() => Activator.CreateInstance(spellType);
}

class Spell 
{
    private SpellBehavior _behavior;
    public Spell(SpellSO so)
    {
        this._behavior = so.GetNewBehaviorInstance();
    }

    public void Cast()
    {
        _behavior.OnSpellCast();
    }
}

[sharp wyvern]

Sorry being silly: I avoid ''var'' like the plague. never clear what it is.

[queen adder]

this is cleaner than switch at least and cool, lemme try if i can like do it

[rich bluff]

in my experience, it goes away after some rounds with stuff like

IReadOnlyDictionary<Dictionary<ICollection, HashSet<Vector4>>> dict = new IReadOnlyDictionary<Dictionary<ICollection, HashSet<Vector4>>>();

after a while it just stops being an issue

[timber tide]

yeah totally var that

[queen adder]

[ExposeType("deliberateGibberishHereCanBeUsedOrStandardGUIDGenerator")]``` it doesnt matter what's in here right?

[sharp wyvern]

hard disagree

[rich bluff]

no just that its unique

and never changes

[sharp wyvern]

if you want one that doesn't use attributes, https://github.com/glurth/SerializableType this one uses the AssemblyQualifiedName. (The editor I made for it sux, but works)

[rich bluff]

assembly qualified name will suffer from all the issues any other type of serialization except attribute suffers

[timber tide]

Reminds me that I need to change some data structs to IReadOnly for my immutable SOs

[sharp wyvern]

oh! tel me more!

what kinda issues?

[rich bluff]

renaming your types will break serialized data

moving into different namespace

[sharp wyvern]

oh! yah, totally

[rich bluff]

https://odininspector.com/tutorials/serialize-anything/refactoring

[assembly: BindTypeNameToType("MyOldNamespace.MyNewTypeName", typeof(MyNewNamesSpace.MyNewTypeName))]

you will still need to use attributes when you will be renaming types

[timber tide]

"Odin's variant was added to support the rare (and not recommended!) case of property serialization."
teehee

[rich bluff]

yes, rare

[timber tide]

Odin is half off right now and debating on grabbing it, but the licensing doesn't seem game jam friendly or unless I'm misunderstanding something.

[queen adder]

cant it work with this set up? Every class need it's own attribute?

[rich bluff]

yes every type needs its own

[sharp wyvern]

AND they must be unique

[rich bluff]

you can just use any Guid generator

like immidiate window in VS

or Insert Guid extension

tbh that lib needs to be refactored to actually use Guid and not strings

my defence is im showing an example of an approach to solving the problem

one of many

[queen adder]

most reliable id generator

[sour hound]

i have made a gun script for my gun that adds recoil to the gun (the gun shakes, but the camera doesnt), and i have a seperate script for using the camera in my fps game (naturally)

i wanted to implement when i fire my camera jerks

and i was wondering whether i would put this "camera jerking" code into the gun script or into the camera script

[twin bolt]

Why isnt this working? '''if (isCrouched && ControllerinUse && ((Input.GetAxis("Horizontal") != Mathf.Clamp(Input.GetAxis("Horizontal"), -0.1f, 0.1f)))) { isCrouchWalking = true; } else { isCrouchWalking = false; }

I'm trying to check if a float is NOT within two numbers.

[slender nymph]

well that's certainly not how you check if a number is within a range.

[twin bolt]

I fixed my issue, but how should i do it?

[slender nymph]

check if it is greater than the max or less than the min to determine if it is outside that range. don't clamp it then check equality. especially with floats where you shouldn't be checking direct equality anyway

[buoyant knot]

yeah, you should actually do two inequalities

==/!= with floats is bad juju

[eager elm]

I would probably put it on the gun. If you put it on the camera than you have to call it from the gun, which means the gun script would no longer work if you transfer it into another project without the camera script.
I guess you could also have an event on the gun that gets invoked when the player shoots, but that feels a little overkill

[solemn fractal]

Hey guys i have 1 prefab for my boss and use instantiate to summon it.. every 1m appear the same boss.. but if u cant kill it will appear again another one in 1 min.. but the prob is some how the second one or both are sometimes sharing or taking damage for the other.. what could it be? Done the same with other enemies and all good.. and its just a prefab being instantiated.. should instantiate it as dif objects and dif hp etc no?

[sour hound]

alright, thank you very much

[timber tide]

What's different about your implementation of your normal enemies and bosses?

[solemn fractal]

nothing all the same.. i have a prefab that I use instantiate toi spawn them in dif times or situations

[eager elm]

maybe you are reducing the health from the prefab instead of the clone when they take damage

[cosmic dagger]

we'd have to see how the damage is applied . . .

[solemn fractal]

private BossOne _boss;
//on start
_boss = FindObjectOfType<BossOne>();
/onTriggerEvent
        if (other.tag == "BossOne"){

            _boss._bossOnecurrentHealth -= _playerBulletDamage;
            SpawnTextAboveHead(_playerBulletDamage);
            Destroy(this.gameObject);

        }```

[timber tide]

Should bind your boss references via inspector instead of finding it through FindObject. Rather, bind the prefab instance then on each instantiation place those new boss references somewhere you can indentify apart from.

[eager elm]

FindObjectOfType() could get either of the bosses and not the one that is going to be hit, right? Why not get the boss from the 'other' object:

other.GetComponent<BossOne>();

then you know it's the one that got actually hit.

[cosmic dagger]

Find will select the first one it finds in the scene. if there are more than one, you have no idea which is selected . . .

[solemn fractal]

hmm ok thank you !! will try

[eager elm]

But you shouldn't care if you hit the boss or a normal enemy. I assume both just lose health right?
You can make use of an interface:

//Create a new script that only contains this
public interface IHitable
{
    public void TakeDamage(int amount);
}
-----------
public class BossOne : MonoBehaviour, IHitable
{ 
...
    public void TakeDamage(int amount)
    {
        health -= amount;
    }
... 
}

private void YourColliderMethod(Collider other)
{
    hitable = other.GetComponent<IHitable>();
    if (hitable != null)
    {
        hitable.TakeDamage(_playerBulletDamage);
    }
}

Then you implement the interface for your normal enemies as well and now your bullet doesn't care about what it hits, as long as it has the IHitable interface it will call the TakeDamage() function from that script.
I highly recommend you try and learn this, if you improve your C# skills you will eventually write the code you are currently writing but in 1/10th of the time.

[calm coral]

This is not a proper way to get an interface component, you need to either cast it to Unity Object or use TryGetComponent() instead. You may read more here

[swift crag]

what? that code is completely fine

[calm coral]

No

[swift crag]

Oh, I see what you're looking at.

You're talking about comparing it to null

[calm coral]

Yes

[swift crag]

That much is right.

I would not say it's the "wrong way to get a component"

[cosmic dagger]

its completely fine, they just have an extra step. it's not necessary but TryGetComponent will do both in one go, yes . . .

[swift crag]

But it is true that this will not test if you've got a reference to a valid unity object.

iirc GetComponent returns an object reference if it fails to find something

[calm coral]

It's not completely fine, it will fail if object is destroyed

[swift crag]

correct idea, just worded weirdly :p

so yeah, you're right: the code is not correct

TryGetComponent is the way to go here.

[calm coral]

Thanks. I'm a programmer, I don't speak human language very well but I'm glad you got what I meant

[swift crag]

I wish there was some kind of way to make a type shaped like

"Any Unity object that implements X"

That isn't possible with C#'s type system

It would vastly improve how you deal with components that implement interface types

[solemn fractal]

well it fixed the prob but now I have another one that in this code ```cs
private void OnTriggerEnter2D(Collider2D other) {

     BossOne boss = other.GetComponent<BossOne>(); 

    if(other.tag == "Enemy") {
        
        Destroy(this.gameObject);
        
    } 

    if (other.tag == "BossOne"){
        
        boss._bossOnecurrentHealth -= _playerBulletDamage;
        SpawnTextAboveHead(_playerBulletDamage);
        Destroy(this.gameObject);

    }
    
    if(other.tag == "BossOneMinions"){
        
        boss._bossOnecurrentHealth  -= _playerBulletDamage / 2;
        SpawnTextAboveHead(_playerBulletDamage / 2);
        Destroy(this.gameObject);
    } 

} ``` the BossOneMinions was working and before was like _boss_bossOnecurrentHealth  -= _playerBulletDamage / 2; and finding the boss witht he find method. the boss minions now gives me object reference not set to an instance in the line ```cs

boss._bossOnecurrentHealth -= _playerBulletDamage / 2;```

but in the line cs boss._bossOnecurrentHealth -= _playerBulletDamage; all good

[eager elm]

because they don't have a BossOne component attached. I recommend you add a reference to the boss in the minion script. When the 'other' object is a minion you get the Minion script and call a method that then will redirect the damage to the boss. I also recommend you read what I wrote above.

[solemn fractal]

ok thank you very much.

[languid gate]

i have a bit of code attached to an object with a 2d box collider and it is a trigger but none of this code is being run on star any ideas why?

        if (player != null)
        {
            Debug.LogWarning("Player found");
        }
        else
        {
            Debug.LogWarning("Player not found. Make sure to tag your player GameObject with 'Player'.");

            Debug.LogWarning("YAYAAYAYAYAYA");
        }
        else
        {
            Debug.LogWarning("Collision with non-player object. Tag: " + collision.tag);
        }
    }
}

[short hazel]

Post a screenshot of the script in the Inspector. It might be disabled

[timber tide]

whatcha colliding with

[languid gate]

the player object with the tag "Player"

[short hazel]

Select the script in your assets (your project files). Its contents will appear in the Inspector, make sure it's identical to what you're seeing in your code editor

[languid spire]

you have 3 LogWarnings there but you have hidden them

[short hazel]

lol

Yep

[gray bough]

Does anyone mind helping me with some script code? I'm following a tutorial for a simple inventory system. I have it working that the object gets clicked and destroyed and saved into an array for the inventory but the UI is not updating with the sprite image and name. I'm not really sure how to fix this and would really appreciate if someone would take a peek at this

Hey, guys! If I don't want to destroy a gameobject on all of my scenes but only for one specific scene is there a way to do that? I mean can I get maybe a reference to my MainScene for example and make it?

[timber tide]

If it exists between all scenes (DDOL) then deleting it will delete that specific instance. Why not just hide it if you don't want to use it on that specific scene?

[gray bough]

`public class InventoryManager : MonoBehaviour
{
public static InventoryManager Instance;
public List <Item> items = new List<Item>();
public Transform ItemContent;
public GameObject InventoryItem;

private void Awake()
{
    Instance = this; 
}

public void Add(Item item)
{
    items.Add(item);
}

public void Remove(Item item) 
{
    items.Remove(item);
}

public void ListItems()
{
    //clean content before you open
  /*  foreach (Transform item in ItemContent)
    {
        Destroy(item.gameObject);
    }*/

    foreach (var item in items) 
    {
        GameObject obj = Instantiate(InventoryItem, ItemContent);
        var itemName = obj.transform.Find("ItemName").GetComponent<Text>();
        var itemIcon = obj.transform.Find("ItemIcon").GetComponent<Image>();

        itemName.text = item.name;
        itemIcon.sprite = item.icon;
    }
}

}` I'm pretty sure this is where my error is gonna be. The part I commented was something I was trying

[summer stump]

```cs
//Your code here
```

Looks like you modify the list while iterating it?
Oh, ItemContent is a transform, so you're destroying children? (Lol)

[gray bough]

Oh? Do you mind if I dm you so I can ask more questions and not spam the chat. If not I can send my questions here

[eager elm]

jesus christ, that code is from a tutorial? Mind sending me a link?

[summer stump]

Best to just ask here, many people more experienced than me are here. If you want, you can make a thread.

[cosmic dagger]

best help will be here where multiple people can have eyes on it . . .

Destroying, instantiating, then using find on that same exact GO is quality

[eager elm]

Does your InventoryItem have two children with the names "ItemName" and "ItemIcon" with the same capitalisation?

[gray bough]

I’ve only made it about halfway through the video because when I stop to test something is always broken

[languid gate]

trying to call this script i made to show a dialogue system

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

public class InteractableObject : MonoBehaviour
{

    public DialogueTrigger dialogueTrigger;

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {

            try
            {
                dialogueTrigger.TriggerDialogue();
            }
            catch
            {
                Debug.LogError("DialogueTrigger component not found on the player GameObject. Make sure the DialogueTrigger script is attached.");
            }
        }
    }
}

But when ever its called it says object not found

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

public class DialogueTrigger : MonoBehaviour
{
    public Dialogue dialogue;

    public void TriggerDialogue ()
    {
        FindObjectOfType<DialogueManager>().StartDialogue(dialogue);
    }
}

i have made public class and dragged the script into it so i dont know why it doesnt work

[gray bough]

public class Item : ScriptableObject
{
    public int id;
    public string itemName;
    public int value;
    public Sprite icon;

}``` This is what I have for the items which is why I think I had to make the var in the ListItems() method

[summer stump]

It is based on gameobject children. Do you have children on the gameobject?

[sage mirage]

Hide it like how? How to hide that instance? I have tried to make GameObject musicGameObject; and after that set that object active to false but that doesn't do what I want, so I want to destroy on load for my main game scene not for every scene. Because I made a dontdestroyonload script and I am not destroying the gameobject of main menu music to my options scene as well but for one reason it still continue playing on my other scenes when loading those scenes.

[eager elm]

Do you have a DialogueManager active in the Scene?

[timber tide]

Maybe getting a null exception from using Find then trying to access the null

this line looks for a child GameObject named ItemIcon. you do not have a child with that name in this pic . . .

I don't know too much about Unity's audio modules, but I'd assume if you're disabling the exact game object with the audio script then it should be prevented from playing so double check on that. Perhaps you need to terminate the current clip from playing before disabling.

[granite raven]

This is the 22 line

playerRb.AddForce(focalPoint.transform.forward * verticalInput * speed);

[ruby python]

Stupid end of the day, very tired, simple maths question incoming. lol.

How can I take a range of 0 - 1.71 and normalise it between 0 - 1 ?

[gray bough]

I changed the "ItemIcon" to "Image" because that's what it's called but the UI is still not updating. But thankfully the inventory manager game object I have still shows that the item is in the inventory array

[granite raven]

thanks for your help... i cannot understand why i cannot use the private GameObject focalPoint

[languid spire]

divide by 1.71

[ruby python]

Thank you.

[cosmic dagger]

looks like focalPoint is null. you attempt to assign it in Start. when using Find, make sure the name is spelled correctly. is the GameObject named "Focal Point" and does it exist in the scene when the script runs?

[ruby python]

🤦‍♂️

[languid gate]

i dont understand why i would need to add the Diaulogue trigger to the player object could u try explaining cause i am really confused

[summer stump]

If you change the name, you need to change the code

[gray bough]

I did not change the name of the object, I just changed the code to match the name of the object

[cosmic dagger]

not sure why you changed the name because the code is looking for the GameObject name "ItemIcon", not "Image" . . .

[eager elm]

That error is generated from your code, or the code you got from somewhere. Double click the error and it should show you the line where the error is getting send from. I don't know the code so I don't know why

[granite raven]

Yes, there is an object called Focal Point. do you think its not finding it because of the space between Focal and Point?

[languid gate]

just relised that was a testing thing from what i was doing earlier

 Debug.LogError("DialogueTrigger component not found on the player GameObject. Make sure the DialogueTrigger script is attached.");```
should i just run it without the try and see the error?

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

public class InteractableObject : MonoBehaviour
{

public DialogueTrigger dialogueTrigger;

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.CompareTag("Player"))
    {

        try
        {
            dialogueTrigger.TriggerDialogue();
        }
        catch
        {
            Debug.LogError("DialogueTrigger component not found on the player GameObject. Make sure the DialogueTrigger script is attached.");
        }
    }
}

}

[granite raven]

@cosmic dagger

[languid gate]

ok i now know how to fix it thanks 🙂

[eager elm]

I wouldn't use try-catch statements there since they hide the real error. I assume dialogueTrigger is not assigned in the Inspector for your InteractableObject

[short hazel]

Oof yeah, I'd just use a Debug.Assert() in Awake or Start for that

Debug.Assert(thing != null, "your error message here")

[languid gate]

it was and issue with the dialogue manager i fogor to define something

but thanks for the advice ill do that next time

[granite raven]

any clue and how to fix the reference error?

[timber tide]

By giving it a reference and making sure it's not null

[languid spire]

have you even tested what is actually null yet?

[granite raven]

i dont want to use

public GameObject name

i want to be able to use a private reference

[granite raven]

Yes, i have a debug.log that is showing that focalPoint is null but in start() i did initiate it

[languid spire]

on the line you indicated playerRB or focalpoint could be null. check it

[sage mirage]

Hey, guys! If I want to get reference for a specific scene in my game how to do that?

[delicate portal]

Why are the objectHitRenderers are null?? Everything seems perfect, and when I debug the meshRendererArray it shows all of the renderers

[rich adder]

to do what with?

[sage mirage]

I dont know can I do that btw?

[granite raven]

thanks for the help. i did test the playerRb and its working... i think is not able to find the Focal Point game object in the scene

[eager elm]

public SceneAsset myScene;

[sage mirage]

I mean not an asset a unity scene?

When I am making a scene in my game that scene

[eager elm]

Try it

[languid spire]

Check the game object name, make sure there is no space at the end

[eager elm]

or add a script to the gameObject and look for that

[sage mirage]

Alright!

[languid spire]

Also make sure Focal Point is not being deactivated

[gray bough]

I updated the name of it but it is still not working. And I also realized that I'm having a separate issue with the inventory where if you close it, all the slots disappear and if you click an item only one slot comes back but it doesnt update and it pauses the game. I'm getting this error but I'm not sure what is null and I noticed it's no longer reading the name of the object (it did this previously)

oops I responded to the wrong message

[granite raven]

OMG bro! u are the best.... i was looking everywhere, even in the entire unity forum... the space at the end of the "Focal Point "
Solved!!! it was a space at the end of the game object name...

@languid spire im glad i found you here, i wasted about 3 hours of my learning today just because of this !!! Thank you again and im sorry, im still a newbbi

[languid spire]

Gotta think like Sherlock Holmes

[eager elm]

I hope the lesson you learned is not to look for things by using strings

[timber tide]

Whenever you call ListItems() you are effectively destroying all gameobjects and creating a whole new set of them, then goes through each new GO to grab the children GOs (text and display). By all means, it probably isn't that big of a deal, but really you should be updating the inventory per itemslot modified.

[gray bough]

Do you mind helping me write those changes? This is my first time working with Unity and C# so I've been relying on tutorials and have been struggling trying to write the code on my own

[timber tide]

Right, so first you need to think about the requirements. Are you having a specific set of inventory slots, or can you modify it later in the game to have more capacity?

[delicate portal]

Anyone could help?

[granite raven]

im not that advance yet.. as soon as i find a better way i will use it

[gray bough]

I have a set amount (25)

[granite raven]

Thanks again Steve!

[timber tide]

So because you know the exact amount, you can just populate the amount of slots on the UI and never touch the composition again. You can even use an array if you want over a list since you know the exact capacity of it all.

[tepid cobalt]

Finally got pooling working!

[gray bough]

I have all 25 in the UI already. And I commented out the destroy(gameobject) in my ListItems() method which fixed my problem of the slots disappearing when I close and re-open my inventory. When I click the items they save in the inventory, but the UI never updates

[timber tide]

What do your slot prefabs look like?

[timber tide]

So, personally instead of using find I would make a script for your slots which have the direct reference to the children

this would cut down the Find() shenanigan's you're doing when you update your inventory

Then with these new scripts you can have your inventory grab these slots by their component (their new slot script) instead of directly using the GameObject reference.

[gray bough]

This is the second inventory system i'm trying to use and the other one had a slotUI script, would the one your suggesting I make look something kind of like this?

[timber tide]

Right, instead of letting the inventory know everything, you break it down so the slots contain their own set amount of data.

[gray bough]

does this script go on the slots themselves?

[timber tide]

Yeah, delcare a set of variables such as their icon and text

you can then directly set these variables on the prefab in the editor, or use OnValidate() and grab the children via GetComponentInChildren()

[timber tide]

icon here can just be the type of Image instead of GameObject

and text would be type of Text or TMP_Text, whatever you're using

[gray bough]

I'm trying to re-use the existing script to fit this situation

[cosmic dagger]

GetChild returns a Transform, not an Image component . . .

And Image does not have a SetActive method . . .

[gray bough]

yes, i changed the type for icon and am now trying to update everything

[timber tide]

You can just change the opacity of Image, otherwise you'd use enabled was it?

SetActive is a method of GameObject

The reason why you want to define your variables by the component and not the GameObject is to prevent binding incorrect types via editor

[gray bough]

I am stuck trying to figure out what to change this to

[summer stump]

What does the error say?
Is icon a transform?

[sharp wyvern]

GetComponentInChildren<Image>() ?

[gray bough]

icon is of type Image

[summer stump]

Well a child is a transform
Get the image from the transform, or do what Glurth said

[gray bough]

this is what I have currently

[timber tide]

GetChild returns a transform

you want to return a type of Image

[sharp wyvern]

icon = GetComponent not icon.GetComponent

then to access gameObject stuff like isActuive or SetActive use icon.gameobject.SetActive...

[wintry quarry]

there is no need for the GetComponent inside RefreshItemIcons

you already got the component in Start

icon is already an Image

[sharp wyvern]

^ good point

[gray bough]

I took that line out, thank you. This is a script from a different tutorial that I am trying to update and re-use

[wintry quarry]

welll... not the line - you still want the icon assignment

[timber tide]

Wasn't there an enabled method for images specifically or am I dreaming

[gray bough]

this is the whole script

[lilac crow]

Hi!
good day.
i need guidance for my project.
i created a menu and i want when it get clicked on its buttons a costume made animation run.
i created the animations But i dont know how to summon it. do i need to use a bool for animator or an trigger?
i ll be thankfull if you tell me how to summon in code?

[timber tide]

When it comes to adding and removing data, that's when you'd update the slot specifically. Your previous script was basically refreshing the whole inventory is the idea of doing it this way instead.

[gray bough]

I’m sorry. I’m having a bit of difficulty keeping up and understanding

[timber tide]

Whenever you insert your item data or remove your item data from a specific slot, you'd set the image and the text for that specific slot. Previously you were having to delete all gameobjects everytime you wanted to display the inventory.

[gray bough]

Ahhh okay

[timber tide]

So, now your inventory script should instead be grabbing all of these slots and putting them into a list or an array for it to navigate through.

[timber tide]

public class Inventory : MonoBehaviour
{
    private List<ItemSlot> slots = new();
    
    public List<ItemSlot> Slots
    {
       get { return slots; }
       private set { slots = value; }
    }
    
    public void Start()
    {
        ItemSlot[] itemSlots = GetComponentsInChildren<ItemSlot>();

        foreach (ItemSlot itemSlot in itemSlots)
        {
            Slots.Add(itemSlot);
        }
    }
}```
Something like that

[upper hearth]

Hey, anyone can help me figure out how I can look around with the camera while also inheriting the rotation of a specific transform?

This is my script for looking around:

                    HeadModeRotationOffset.x += mouseX;
                    HeadModeRotationOffset.y += mouseY;
                    HeadModeRotationOffset.y = Mathf.Clamp(HeadModeRotationOffset.y, -90f, 90f);

                    Quaternion yQuaternion = Quaternion.AngleAxis(HeadModeRotationOffset.x, Vector3.up);
                    Quaternion xQuaternion = Quaternion.AngleAxis(HeadModeRotationOffset.y, -Vector3.right);

                    transform.rotation = yQuaternion * xQuaternion;

"targetPosition.rotation" is the head variable that I want to inherit its rotations (bobbing)

[worn ether]

How's the camera in your hierarchy?

[upper hearth]

It's not parented by* anything

[lament silo]

Item selectedItem = GetSelectedItem(false);
        
        if (selectedItem != null)
        {
            if (itemHolder.childCount <= 0)
            {
                selectedItemModel = Instantiate(selectedItem.model, itemHolder);
                IEquippable tool = selectedItemModel.GetComponent<IEquippable>();
                tool.Equip(itemHolder);
            }
        }
        else
        {
            Destroy(selectedItemModel);
        }
```Anyone has any idea on how to make it work properly? (Whenever I hold 1 item and then switch to other, it doesn't change the viewmodel. To fix that I have to switch to empty slot and then switch to desired item)

[worn ether]

You can't parent the camera under the transform you want?

[upper hearth]

I would rather avoid that. I'm trying to only inherit the head* bobbing in code

[timber tide]

Assuming your tool.Equip method isn't throwing errors, then I don't see anything wrong with this code here. Probably explain it a little more if possible.

[worn ether]

I do head bobbing by just moving the local position of the camera, specifically just the Y axis, that's parented under the Player game object. But that's for a first person game setup.

[upper hearth]

Yeah I don't want to make it parented by the game object. The only thing I'm getting out of chat gpt is to multiply the rotation of the head like this:

transform.rotation = targetPosition.rotation * (yQuaternion * xQuaternion);

But this messes up my controls and everything...it does however inherit the head rotations correctly

So I just want to inherit those head rotations without messing up my camera's looking around feature

[worn ether]

How is that you want to do the head bobbing? Is it suppose to rotate more or less like in a call of duty game?

left and right

You can store the look around code in a variable and then apply the bobbing rotating by the end of the Update method

I've done this a couple times to apply stuff like head bobbing and camera lagging to kinda "force" the transform to assume a specific rotation or position

So you modify each variable independently and then apply them up at the end so each effect don't interfere with each other

[gray bough]

this being a new script?

[timber tide]

New being the purpose of the inventory script now. It'll manage the slots, but the slots now have their own individual instance of datas.

[upper hearth]

When you say apply the bobbing rotating, you mean manually add the rotation or actually inheriting the rotations?

[timber tide]

If you want to check if a slot is unoccupied, you'd consult the inventory and it'll look through the slots and return an index to insert data into if available.

[worn ether]

Manually add the rotation. You have code that controls how the camera looks around. Save that to a property and then at the end calculate the head bobbing, and then apply both the look around property and the head bobbing to your transform rotation.

[novel shoal]

what's the problem here? the first script is for the movement, the second is to disable the movement if there is a collision, and the third is to make obstacles not move at all if hitted

[lament silo]

Sorry, I will explain tomorrow, it's too late rn

[gray bough]

so now these are the scripts that I have

[lilac crow]

No One??????????

[summer stump]

You enable and disable its own script. Never the movement script

The name of the variable is irrelevant. It's the type that matters

[novel shoal]

so i have to call the movement script, but how?

[summer stump]

By making the type objectSpeed instead of ObstacleBehaviour or ObstacleCollision

Then drag in the script

I strongly recommend stopping and doing this

It's short and will help tremendously.

Then move on to this. It will help you specifically with unity

the beginner pathway is not working

i am doing a tutorial

[summer stump]

Do the c# course first anyway
Don't do youtube first

[novel shoal]

but i wanted to try to do something with what i know

[timber tide]

Inventory, Slot, and however you're managing your item data (which should have a variable declared inside of each slot for them)

[summer stump]

Well, I don't know if you are at the point for that. Making a reference is just about the first thing you should learn after what an int, string, etc are

But you can certainly make your own choices

[novel shoal]

sorry

i'll learn to learn

[summer stump]

No need to be sorry. I don't mean this to be rude, i just want to see you succeed and not burn yourself out.

The course i recommended is short. You'll do great

[novel shoal]

ty

which is the c# course?

[gray bough]

variable in the prefab? or somewhere in the script?

[summer stump]

The w3schools one

[upper hearth]

Alright thanks

[novel shoal]

@summer stump

[gray bough]

w3school is a website

[novel shoal]

oooh

[gray bough]

they offer different courses for languages

[worn ether]

freecodecamp has some good ones too

[gray bough]

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

[worn ether]

they released a C# certification course recently

[novel shoal]

i know a bit of c#, can i skip what i already know?

[summer stump]

No. You need the very basics of c#, that is where you are struggling

At least learn what a type is

[novel shoal]

int, float, bool

that right?

[summer stump]

Those are primitive types yeah

Now learn what non-primitives are

[novel shoal]

ok

[wintry quarry]

every time you do public class < something > you are creating a new type

same with struct and enum

[summer stump]

Just keep in mind that Unity is just a c# api. Knowing c# is the most important part. Then learning unity is much easier

[novel shoal]

ok ok ty

i'll learn it

i already coded a bit in python so i hope it will be easier lol

[summer stump]

The biggest difference is gonna be typing. Python is dynamically typed while c# is statically typed.

There are 100 other differences, but that's the one python users seem to struggle with most in my experience

[novel shoal]

okk

see ya

[lilac crow]

im sorry can Anyone help me?
i created a menu and i want when it get clicked on its buttons a costume made animation run.
i created the animations But i dont know how to summon it. do i need to use a bool for animator or an trigger?
i ll be thankfull if you tell me how to summon it in the code?

[crude prawn]

yeah you can use a bool for it

for instance animator.SetBool("Run", true)

need to create a bool in the animator tab and transition it though

[granite hedge]

Has this happened to anyone else before? Project and assets all imported properly everything completely fine, but then you load your project and everything is blurry? Thank you!

[lilac crow]

so how do i relate it to button on menu?

[timber tide]

You declare an item variable inside of the slot but you don't necessarily need to reference an item just then. So technically you iterate over your slots from your inventory and check each slot if it has set data or if the item variable is null. If it's null then that means it's empty and you can insert a new item reference into it.

[crude prawn]

you create a new public function and set the animator bool to true on that function

and drag it to the button

[sour hound]

im making adding a recoil effect to the camera when i fire my gun where the camera "jerks" upwards on the OnGunShotEvent, however i have a problem where the camera keeps returning to its original position after it has jerked upwards and i have no clue why

https://hatebin.com/rwmnmsogpy

[lilac crow]

like normal run animation?

[green mirage]

Assets\Origami\Assets\Holograms\Support\Spatial Mapping\SpatialMapping.cs(27,13): error CS0246: The type or namespace name 'SpatialMappingCollider' could not be found (are you missing a using directive or an assembly reference?)

I am importing the hololense v1 tutorial and getting this error. What do I need to do to fix this

[crude prawn]

what do you mean

[spare mountain]

is there a script called SpatialMappingCollider?

[green mirage]

yea

[lilac crow]

i mean for my run i made an float in animator and gave it a condition for walk and a made a bool for run saying if shift is held make it true.

[green mirage]

sorry no

there is not

[green mirage]

I don't see one

[lilac crow]

i saw this on many toturials

[spare mountain]

then that's probably why
where's the script?

[crude prawn]

so what are you looking to do then?

when u click a button the run animation is set to true?

[green mirage]

https://github.com/Microsoft/HolographicAcademy/archive/Holograms-101.zip

This is the project folder, we drag and dropped it to assets

https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/tutorials/holograms-101

in unity 2019 lts

it's the v1 hololense but it should have all the files

I'm wondering if it's our verson of xr plugin or something?

[lilac crow]

i did'nt know to use trigger or bool for it ? and i though because its menu button i should use a diffirent method.

[lilac crow]

thanks for guiding me.

[crude prawn]

well its the same thing as u did with clicking on left shift

[crude prawn]

no problem

gl

[green mirage]

why would they upload it with missing scripts on microsofts website?

[viscid sparrow]

Is there a way to prevent pixel art from doing that individual pixel slant thing when it is rotated?

[spare mountain]

are you missing some other package or something?

[spare mountain]

anti aliasing?

[green mirage]

I don't think so, We have xr plugin installed

[spare mountain]

I wouldn't know enough about this package to say for certain
see if anybody else has had this issue online maybe

[viscid sparrow]

anti aliasing is not affecting anything

[spare mountain]

can I see your sprite

[spare mountain]

and show it how it looks when slanted?

[viscid sparrow]

y'see how it has that weird slant on the pixels? Do you know how to fix that?

[spare mountain]

those looks bumpy, not pixelated

can I see your sprite's settings?

[spare mountain]

try setting compression to none

[viscid sparrow]

doesn't do anything

[spare mountain]

looks the exact same?

[viscid sparrow]

yeah no changes

[spare mountain]

I might check #🔎┃find-a-channel since this channel is meant for code, there might be some more experienced people with sprites there

[gray bough]

would this work?

[spare mountain]

this will work for the first null item only

are you running it multiple times?

[timber tide]

Looks fine for the most part

[sour hound]

im making adding a recoil effect to the camera when i fire my gun where the camera "jerks" upwards on the OnGunShotEvent, however i have a problem where the camera keeps returning to its original position after it has jerked upwards and i have no clue why
https://hatebin.com/rwmnmsogpy
i just want it to jerk upwards, forcing the player to pull the mouse down to combat the recoil

[gray bough]

Do I attach the Inventory.cs script to an empty object that acts as a handler? Or to the inventory prefab objects themselves?

[timber tide]

Yeah, it would be in the scene. It be the parent of all the slots.

[minor jungle]

sorry if this is the wrong chat i could not see anywhere to put it. So i use this ````else if (addTicketsCommands.enabled && addTicketsCommands.commands.Contains(command))
{
if (!addTicketsCommands.adminOnly || IsAdmin(username) || (addTicketsCommands.streamerAllowed && (username == TwitchChat.Instance.channelName || username == TwitchChat.Instance.nickName)))

}

{
TwitchChat.Instance.SendChatMessage("@" + username + ", Could not add tickets to player.");
}
}
}
}``` which is a admin command to add tickets to someones account by doing !addtickets @(username) x-amount but when i try and set it so any one can use the !addtickets 300 i cant seem to get it to pick up the person that used the command or add the tickets and anyone help

[spare mountain]

this channel is for Unity concepts
I'm sure there's a discord.js discord server, or something similar, I would ask there

[minor jungle]

its a unity scipt not a discord script

[spare mountain]

ah, my bad
your command looked like a discord command

you're good then

[minor jungle]

the script sets up this https://i.imgur.com/gybUXeJ.png but from the code it reads as game admin command but i cant get it to work so they can use !claimtickets and it will add x amount of tickets to the person

[spare mountain]

as in it's not registering someone sent the command?

[minor jungle]

https://i.imgur.com/JRr9eS2.png

Thats what im getting so im guessing the code is wrong but i cant work out what

[gray bough]

I'm am once again trying to repurpose code I've already written from a different tutorial but am having trouble editing it

[green copper]

I'm using this code to move a selection arrow up and down on a list. Only problem is, when the aspect ratio changes when the menu is open, it becomes misaligned. If the aspect ratio is changed, and the pause menu is closed and reopened, it works as expected. It only occurs when the aspect ratio is changed while the pause menu is open.

The pause menu is a canvas, set to Screen Space - Camera, with an orthagonal camera.

[queen adder]

https://docs.unity3d.com/2017.3/Documentation/ScriptReference/UI.LayoutRebuilder.ForceRebuildLayoutImmediate.html

this method force UI's to adjust, not sure if that was the problem though

[spare mountain]

to be clear, you do want the AddItem command to only change the FIRST null item in the slots list, correct?

[wintry quarry]

you seem to be mixing up yout slots and itemSlots variables

[gray bough]

the first available. So for the first object, fill the first slot, if first slot full, fill the next available slot

[green copper]

I have a related problem I think I'm realizing, if the player presses enter on the Options menu, it also applies one instance of hitting enter to the first option on the options menu itself. So it essentially treats inputs that open submenus as double inputs

[spare mountain]

which is what I described (considering empty slots are null)

[wintry quarry]

also the length of a list is .Count, not .Length

[queen adder]

lol, even google giving my unity2017 docs by default

[queen adder]

it was because of navigation in your button ig

[gray bough]

then yes

[queen adder]

check your button's navigation and turn it to none (if you have it on, and also have your own script that does the same, it double clicks)

[green copper]

This is the function that handles that

It may or may not be very cursed this is my first attempt at a full UI

[tender breach]

I know I already made a similar thing, but nothing happens when a gameObject is on a certain point on the y axis.

[queen adder]

oh, tmp thingy, cant help in there

[tender breach]

tmp?

[queen adder]

textmesh pro

[tender breach]

What's that?

[green copper]

Oh that's a leftover pass actually I changed how I handled that

[queen adder]

yea nvm realized it's irelevant

[gray bough]

now that I'm looking over it again, should my AddItem go in Inventory or InventoryManager?

[queen adder]

are you sure that method is called twice? Put logs in there first

[green copper]

yeah the function is only run once

it just resolves activateOptionsMenu(), then in the same game step, resolves the if activeMenu "Options"

so I need to add a break somehow

[queen adder]

use returns instead of break then?

after activateOptionsMenu()

or actually, just use else ifs

makes life simpler

[green copper]

adding a return after the switch worked as well

might refactor it for else ifs later

but fixing that didn't solve my aspect ratio arrow misalignment issue sadly

[queen adder]

did you read the docs i sent?

the method that refreshes recttransforms

[green copper]

I tried binding the aspect ratio changing function to a key, and it doesn't break in that instance. It's only when I activate it in the mainGameManager that is misaligns

reading those now

I'm a little confused

how do I call the method?

the only code it gives is declaring it?

why would I need to declare a unity built in method

[static cedar]

[queen adder]

ForceRebuildLayoutImmediate(yourMainPanel'sRectTransform)

there's some using for it afaik

[green copper]

you mean the canvas? What's a "panel" in this context?

it also says the function does not exist

[queen adder]

            LayoutRebuilder.ForceRebuildLayoutImmediate(mainmenu.transform as RectTransform);```

not the canvas, just your mainmenu thing

[timber tide]

Your member variable(s) here are slot, and itemSlots is just a local variable to define the components. Your InventoryHandler script may not be setup correctly if you're using it as a singleton.

[raven trench]

alright i asked this yesterday and i got some help but i am still struggling immensely, i need to know how to acess a variable from a different script

• i have one script with public int Money = 1 on a box
• i have another script that has i want to access the money on so i can add and subtract it using that box
  i have no idea what im doing 😭

[ivory bobcat]

Reference the other object with the script.

[raven trench]

dude i been TRYIN but i dont know what that means mannn

[queen adder]

https://youtu.be/Ba7ybBDhrY4?si=igvr2-TNZ2AFItC0

[raven trench]

alr ill watch this and come back if im still somehow confused 🙏

[summer stump]

I think I linked this yesterday.. but just in case I didn't:
https://unity.huh.how/programming/references

You want a serialized reference if possible

[raven trench]

yeah you did but im still at a loss cuz my reading comprehension is negligible

yeah im still having issues like i can get the serialize field thing to open but im not sure what im supposed to be putting here

hold on lemme try smt before

yeah no i think im just braindead 😭

[summer stump]

You put an OBJECT with the script you want into it. You can't put in a script itself

So like:
public MoneyScript money;

Then you drag an object with the MoneyScript into that field

[raven trench]

ok first off which object am i putting the serializefield thing on, the one with the money variable or the one i want it on?

ok hold on

i thinkk i got it

lemme test

[ivory bobcat]

You need to make a field that's public or serialized with a type that's the script you're wanting to access.

[raven trench]

so i switch out MoneyScript for the actual name of the script right?

[ivory bobcat]

Next using the inspector, drag and drop the other object with the script into the inspector-field.

[raven trench]

but my goal is to subtract stuff from it and when im trying that out it says i cant because its not an integer anymore or smt?

[ivory bobcat]

That doesn't matter. Get a reference to the script from the other object first.

[raven trench]

i have that part here man

[quasi rose]

money = target controller? 🤔

[ivory bobcat]

Now you should be able to do Money.Money -= 1

[raven trench]

the money int is on the target controller script thats why

[quasi rose]

very confusing but gotcha

[ivory bobcat]

Assuming the integer field is called money as well

[raven trench]

well cuz you gain money by hitting the target so

[quasi rose]

I think you might be having a hard time understanding references, by your choice of Money variable name.

[raven trench]

what else would i name the variable representing money if not money

[raven trench]

does -= mean +?

[quasi rose]

Typically when you want to reference a script, which is what you're doing, you write the same name, just different casing. You're not really referencing money (although you are able to access that), you're referencing the script itself.

So MyScript.cs , the reference would likely become myScript.
Then from there, you access myScript.money.

It doesn't matter from a functional standpoint, but it's clear you don't quite understand what you're doing here just by the naming.

Hopefully that helps clarify a bit.

[ivory bobcat]

It's a shorthand for A = A - 1

[raven trench]

oh ok ty

[quasi rose]

because for example, you could also do myScript.bankAccount, etc. it's not just money.

[raven trench]

that does not infact clarify it because i do not infact understand what im doing generally

[quasi rose]

Start a thread and I'll explain if you actually care. Otherwise, all good.

[gray bough]

I don’t want to use the InventoryHandler but I was sure how to rewrite the script to not use it

[timber tide]

Your slots will handle the update of individual UI elements themselves when you start adding/removing from them.

if(slot.item == null)
{
  slot.item = newItem;
  slot.image = newItem.image;
  slot.text = newItem.text;
}

[ivory bobcat]

Wouldn't that yield NRE?

!= null

[quasi rose]

it's setting it.

[queen adder]

slot is the one checked though

[quasi rose]

(i didnt read any further above) lol

[queen adder]

if slot is null, slot.item is null too

[timber tide]

sorry I mean slot is always set

it's the item that is null, also text is probably the quantity which is more than just setting the text but appending values

[quasi rose]

ah yea

[ivory bobcat]

Ah, all good now

[quasi rose]

i see now

[gray bough]

can I send what my scripts currently have? I have to update referenced names but I want to double check the logic before I try and do so

Hello, how does the Raycasting function work in unity?

[gray bough]

Inventory.cs or InventoryManager.cs get rid of?

[timber tide]

InventoryManager.cs

[summer stump]

It is a spatial query that returns true or false if it hits a valid collider

What specifically would you like to know more about?

[deft stirrup]

How i use this?

[summer stump]

Depends on a lot. 2d or 3d?
Want it to only hit certain things?
What will it be used for?

[wary sable]

What would be a good way to get the number value of a keypress? (Say the user presses 4 and this magical function returns the int 4)

[ivory bobcat]

New input system or old?

[wary sable]

new

[ivory bobcat]

With the old, you could probably do a loop with every possible key etc

[wary sable]

yeah I was hoping there was a more elegant solution than a big loop or if else tree, but if thats the way it needs to be done its not the end of the world

[wintry quarry]

By far the best option is to create 10 actions and just map them to the numbers

This gives you full support in the system including rebinding etc

[wary sable]

I'll definity give that a go, thank you!

[craggy ledge]

would a state machine for movement and attack something like this be ok or no?
Should movement and attack be seperate?
Or is there a better way to do chain attacks?

[gaunt ice]

is there transition from jump attack1 to idle (or other state that can go back to idle)?

[craggy ledge]

Oh yeah, now that i think about it every state actually, if you don’t continue the attack or grounded after jump/jump attack

[pulsar lodge]

I am having some issues with collisions using 2D box collider and rigidbody. This is a snippit of my code for detecting things on the solidObjectsLayer i've defined that i do not want to walk into.

It "works" but my character get stuck on the object and screen starts bouncing

Here is the rest of my movement code

[summer stump]

For one thing, you never want to do input in FixedUpdate

The coroutine that you start every time you can move is concerning. You are gonna be starting it multiple overlapping times it looks like

[pulsar lodge]

if i drop the coroutine and swap IEnumerator to just void, i get a vector 3 error, not sure what to do about that to be honest.

I may need to redo my movement code, i was able to get it working with different code, it just functions differently than i'd like, I want it to be very old school "tile movement" moving 1 position / coordinate at a time, rather than the "fluid" movement when i use the code that i have commented out.

[summer stump]

I did miss the IsMoving bool
So that should negate the issue I mentioned

[teal viper]

No one knows what a "Vector3 error" is. You need to provide a bit more details.

[pulsar lodge]

yes, isMoving is set to no by default.

sorry thats at the top, only sets to Yes when Move is called, then No again at the end of the method

[teal viper]

What line is the error thrown at?

[teal viper]

You can't use yield in a method with no return type

It seems like it was a coroutine before, but the same code wouldn't work as you expect in a normal method.

[pulsar lodge]

Rofl, well. the collisions work without the coroutine, but

my character is moving like 1000 times faster

[teal viper]

Yes, because you're moving it right to the target position within that Move method.

Here's a secret about how computers execute code: they do it line by line. Untill your Move method gets you to the target position, it wouldn't let unity update.

[pulsar lodge]

Well, i do want to move to that target position, rather than a smooth movement, i want the movement to be very gridlike (think pokemon, old school final fantasy, etc.)

[teal viper]

In this case you need to decide on a fixed rate at which you move your character between the points.

But here's secret #2:
Collisions wouldn't work properly if you move the object in a physics incompatible way, like you do.

[pulsar lodge]

Well, thats what the isWalkable bool method "should" be there for, maybe that is what isn't working properly.

[teal viper]

Well, with your current code this runs once, then you move your character to the target designation in one go, then unity updates and it runs again, but your character is already at the target.

Though, I guess the target is just the neighbor tile

[pulsar lodge]

if i remove the rigidbody and box collider 2d from the player, it will work also, but then i have issues with triggering scenes, (entering a town, etc.)

[teal viper]

I'd assume that the overlap isn't working as you expect. What's with that .1 radius?

It's probably smaller than your character.

[pulsar lodge]

I played around with different values to get it working before i started adding my triggers, .1 seemed to be the sweetspot for the isWalkable method at the time for my character to slide just in between tiles, i then came accross an issue with triggers not working at all unless i put a 2d box collider and rigid body on the character, which now that i've done that, the fricken colliding isn't working

[teal viper]

Wouldn't that detect the tile too late? You need to already be within the non walkable tile for it to return true. Is that what you want?

[tacit flame]

Im trying to make a 2d Unity Project and i keep getting this Error

whats going on

[pulsar lodge]

well im passing it into a variable to see the "next tile" with var Target pos = transform.position; and targetpos.x and y += input.x and input.y

at least thats what i imagined it would do lol

i want that when my bullet collides(using on trigger) with someone having Enemy tag then it should get destroyed and based on that totalenemies variable should be -= 1

in the Score class

[upbeat gorge]

oh ok wait

[upbeat gorge]

Thank you so much

its working i just forgot to assign it

so what if i want to spawn objects

like this find gameobjectswith tag is in start

[rare basin]

what do you want to do?

[upbeat gorge]

i want to spawn GOs

gameobj

but i used find gameobjwithtag in start

[rare basin]

how is that related?

oh, you wanto spawn enemies

and add them into the array of enemies?

[upbeat gorge]

yes

[rare basin]

i'd just make the ScoreManagre a singleton, and in the Enemy class in Start() add them to the array of enemies

so each enemy add himself to the array

instead of the ScoreManager looking for every enemy

[upbeat gorge]

how to achive it?

[rare basin]

google it

https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[upbeat gorge]

oh its a thing

[rare basin]

then after you have a singleton from ScoreManager
in your Enemy, in Start() just do ScoreManager.Instance.Enemies.Add(this)

and make the Enemies a List<Enemy> not an array

you cannot add elements to the array dynamically in an easy way, just use a List

[abstract finch]

        {
            _currentModifer = Mathf.Lerp(start, target, time / duration);
            time += Time.deltaTime;
            yield return null;
        }```
How would I be able to implement an AnimationCurve.Evaluate into this loop?

[rare basin]

depends on what are you trying to achieve

[abstract finch]

Its a recoil coroutine, so for the recovery I want to have it start veyr slow then quickly ramp up to reach its target

Basically similar to pulling the gun to its original position after firing

[rare basin]

so you want to modify the currentModifier value based on the animation curve?

[abstract finch]

ye[

yep

[rare basin]

well, make a animation curve (obviously)

[abstract finch]

yea but where do you plug in the animation curve?

[rare basin]

are you using this code in an Update

or coroutine

[abstract finch]

nope its a coroutine

[rare basin]

good

then i'd do something like that

    float time = 0f;

    while (time < duration)
    {
        float curveValue = recoilCurve.Evaluate(time / duration);
        _currentModifer = Mathf.Lerp(start, target, curveValue);
        
        time += Time.deltaTime;
        yield return null;
    }

[abstract finch]

ohhhh

thanks

[rare basin]

just evaluate the curve and use this in the lerp

[abstract finch]

got it thanks

[rare basin]

that works too

[abstract finch]

i wonder if its better to just instead of having two coroutines for the recoil and the recovery. what if I just do one coroutine that uses a curve such as this? Is that common? This way I get both the recoil and recovery in one value.

going to try it actually

[somber wren]

hi guys, im instantiating a missile here but i want it to point forward. but for some reason, it always points in a different direction depending on my spider rotation and forward

and here is the prefab im cloning

[teal viper]

It looks like it's just the original orientation of the mesh that is wrong.

[somber wren]

it looks like it worked magically after 200 tries on different line of code and then going back to the beginning

[ruby python]

The Z Axis (Blue arrow) on your missile is pointing out to the side, so that would be the missiles 'forward' direction. Generally you would create an empty to be the 'root' of the prefab and then make sure all the rotations of the child objects (missile mesh/particles etc) are rotated to align to the empty.

[gaunt ice]

or set the transform.right

[somber wren]

but if i change it change the pointing direction :(

its velocity is just its updward direction now, its fine i think

[stoic spear]

hey everyone, im trying to make wheels that rotate depending on the velocity of the car, but as soon as the wheels rotate 90 degrees either direction they just kinda stop?

visualWheel.localEulerAngles = new(visualWheel.localEulerAngles.x + wheelVelocityLS.z, steerAngleLerp, 0);

this is in FixedUpdate()

[topaz mortar]

I wanna start on a game where the character just falls down a huge pit and if it hits something it dies
The walls should be collidable, so you can't go through them
The floor should be collidable and trigger character death
What's the best way to set up these collisions? Since my character won't be interacting with the collidable objects most of the time

[hoary halo]

Just have it so if it collides with floor it will call a method which does what u want when it dies. And the character has a rigid body that u probably want to control using wasd
And add just colliders to the 3d objects

[eager elm]

that is not valid code

[stoic spear]

yeah it is

[eager elm]

= new () ... new what? I assume Vector3?

ah damn, it actually is valid 😄

[fierce shuttle]

C# 9 feature, really interesting one, I havnt seen it used often but if the left hand type is known, the right hand side doesnt need the type again when newing it, same with default and default(T)

[eager elm]

if it stops turning it probably means that localEulerAngles.x + wheelVelocityLS.z is 0. What exactly is wheelVelocityLS.z? I think your local angle goes from 0-360 and your wheelVelocityLS.z goes from -180 to 180, so when the wheel is at 90° you set x to 90 + (-90) = 0. Try adding 180 to the second value. Also, if it is a quarternion you might want to read it's eulerangles instead @stoic spear

[wintry quarry]

Recommend not trying to read euler angles from the Transform, it always leads to these issues

[harsh owl]

why is my car keep getting teleported higher than my set hover height? and also when the car is higher than desired hover heihgt its not getting pulled down it just stays up there

[rare basin]

i wouldn't do that personally

as when it's splitted you have more controll over what are you doing

and you can fire additional events such as OnRecoil, OnRecovery etc

with one coroutine it will be harder to achieve

the issue is I want that once an object collisions with my player it inverts controlls (speed is set negative)

[near saddle]

before i start coding a* pathfinder should i create a graph in my game

[ionic zephyr]

i havent completed the code)

but I want it to wait 5 seconds until having the controlls normal again

[verbal dome]

You need some nodes to traverse yes. It could be a simple grid

[rich adder]

is the log printing?

IEnumerator VuelveNormal()

[ionic zephyr]

let me check

sorry it is in spanish

it isnt

[rich adder]

then the coroutine is never started

[ionic zephyr]

sorry, Im a little noob. Is the coroutine the same as a method?

[rich adder]

IEnumerator

[ionic zephyr]

yes I mean theorically the StartCoroutine is like a mention to call a method

[rich adder]

if Line 42 is not printing the coroutine was never started

[ionic zephyr]

so how can i assure it starts?

[rich adder]

make sure the if condition is true?

start by debugging your triggerenter

[ionic zephyr]

the condition is fine because the speed turns negative

as it says in the condition

[verbal dome]

It is a method to start a coroutine

[ionic zephyr]

what is a coroutine?

sorry for all the questions

[rich adder]

IEnumerator lol

in unity

[polar acorn]

This object wouldn't happen to be on (or a child object of) Tuerquita, would it?

[verbal dome]

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

[ionic zephyr]

it is not child object of anything

[rich adder]

are you sure its active the whole time?

[polar acorn]

So, the InvertManager object is never destroyed or disabled?

[ionic zephyr]

it is destroyed once it contacts the player

oooh

i had unable before the Coroutine thing

could it be that?

[polar acorn]

If an object is destroyed or disabled, all coroutines currently running on it are canceled

[ionic zephyr]

it still doesnt print the debug

therefore it doesnt execute the order

[polar acorn]

Does it print the first debug

if it doesn't print the first one, then that code is never run

Either the condition is never true or the OnTriggerEnter2D itself doesn't run at all

[ionic zephyr]

the first in the IENumerator?

no

[queen adder]

I am trying to assign a material to a 3D object plane but the plane is still transparrent for some reason. Anyone help please?

not a code question

[ionic zephyr]

the one inside the IEnumerator you mean right?

Ok, tell me where to put my question then.

[polar acorn]

If the first log doesn't run, then the StartCoroutine line is never reached

[wintry quarry]

#💻┃unity-talk

or #🔀┃art-asset-workflow

[ionic zephyr]

this is wierd. I put the setactive(false) into the coroutine thing and it executes but not the debug

then you probably have debugs collapsed or somethin

but it doesnt set the speedvalue to the normal one either

[reef anvil]

apologies to be barging in, but i cannot figure out for the life of me why im not getting a console output from this?? (the interaction system is ripped straight from a tutorial so i dont think anything is wrong there, it works and gives console outputs with a test script i made)

more info is probably needed, ill be happy to provide

oh right, Plaque is a super simple struct i made (still just learning about OOP)

[polar acorn]

Show a screenshot of your full unity window, with the console visible, after this is supposed to have printed

[rich adder]

why are you looking for IInteractable but script is called PlaqueZero?

if IInteractable is an interface it shuld be implemented in PlaqueZero

[reef anvil]

yep, thats the issue

thank you!

very stupid oversight

it needs to be there after : MonoBehaviour like it is in the other script 🤦‍♀️

[rich adder]

yeah thats what makes Interfaces modular

you can add as many as you need to a class eg public class Foo : MonoBehavioir , IInteractable, ISaveable, IDamagable

[reef anvil]

code works now

[ionic zephyr]

what is this

[rich adder]

it means you added something new to prefab thats not on the original

[ionic zephyr]

oh okay

[wintry quarry]

new file in version control

[rich adder]

is it? ohh

[ionic zephyr]

which means...

[wintry quarry]

which means you created a new file and haven't committed it to the repository yet

[reef anvil]

okay, now on to getting ui to pop up when the variable is true (this is a very stupid way of doing things because i'll need a separate script and separate ui element for each of the 50 plaques i have, but if its stupid and it works its not stupid)

[rich adder]

or you added something new to a prefab 🤷‍♂️

[wintry quarry]

oh right

you're right

I was thiking this was from the project window

[rich adder]

do they use the same icons lol

oh wait i think VC is a checkmark

[wintry quarry]

I'm not actually sure because I don't use Unity version control integration

[rich adder]

huh could've sworn they were green 🤷‍♂️ but yeah i dont use it myself I just recall the prefab + icon in 2022 changed

[ionic zephyr]

IEnumerator VuelveNormal()
{

 Debug.Log("entraenIEnumerator");
 _myManoloMov.speedValue = -_myManoloMov.speedValue;
 Debug.Log("antes de wait");
 yield return new WaitForSeconds(5f);
 Debug.Log("pasan5secs");
 _myManoloMov.speedValue = 0;

} when the code gets to the yield return, the rest of the code doesnt work

why??

the debug, for example, doesnt execute

[wintry quarry]

If a coroutine stops at a yield and never resumes then either:

• You set Time.timeScale to 0 or a low number somewhere
• The GameObject that was running the coroutine was deactivated or destroyed
• The coroutine was stopped with StopCoroutine

[ionic zephyr]

okay, let me try, thanks a lot

i checked and i dont do that in any part of the code

[wintry quarry]

You'd have to show the code

and explain what this code is and how it's working

where the coroutine is started from and how

etc

I'm still waiting for that screenshot

#💻┃code-beginner message

[ionic zephyr]

I already sent it

[rich adder]

this isnt what they asked

is this console or unity window?

[ionic zephyr]

visual studio

[rich adder]

then its not what they asked is it?

[ionic zephyr]

oh okay

the error there is not the problem

ive been having this error there for a while

[polar acorn]

Fix it anyway

It could be

When an error occurs, code stops

At the very least it'll make the console cleaner

[keen dew]

You can't know that this script doesn't throw an error because the console is flooded with errors from the other script

Sorry if this is the wrong place - I'm mostly new to unity and very new to this discord, but I am an experience C# dev so not sure if this is the correct place to ask

I'm trying to write a custom editor that at its heart will store a set of selected prefabs + some misc data associated for use in runtime code later down the line, I've never done any kind of state-based stuff in Unity and at first was going down the line of storing my data as JSON, but I've since read that changing my classes to be ScriptableObject's would be more appropriate, but it doesn't seem to behave like I would expect.. infact, the behaviour is very odd and I dont fully understand it, and I'm struggling to come up with the correct terms to google

So, I have a "tileset" ScriptableObject, code here: https://hastebin.com/share/bafolonoge.csharp
That has a List<tiles> property, tiles being another ScriptableObject that has a GameObject field called tilePrefab, code here: https://hastebin.com/share/okidizugim.csharp

I then have a TilesetEditor class that inherits from EditorWindow, basically I want this to be able to take a TileSet in my assets list and let me modify the linked prefabs and such from within the unity editor, code here: https://hastebin.com/share/icohusuger.csharp, then for debugging I have a TilesetInspector class that just adds a "Tile Count" to the inspector window when I click on the TileSet object in my assets folder.

With all that out the way, I think the way I am saving the connection to the prefabs is somehow wrong... right now I don't know if its in the way I have set up my Tile object, or if its how I've scripted the editor to allow editing it, but I've tried a few different iterations of this and cannot get it to work.

When I open my editor, I can add tiles, the tilecount in the inspector goes up, hitting save in the editor causes my .asset files modified time to change.. but closing & re-opening unity resets the ScriptableObject to empty

Now that I typed that all out I'm not sure it can be to do with the Tile object, since regardless of if its a GameObject or some other abritrary property I am setting, its the List<Tile> that resets, not the tiles themselves... is it to do with my constructor on TileSet to initialise List<Tile> = new List<Tile>() perhaps

[ionic zephyr]

do you know what the error could be

[polar acorn]

The variable health of HealthManager has not been assigned.
You probably need to assign the health variable of the HealthManager script in the inspector.

[ionic zephyr]

there isnt any variable in the inspector i can assign

[eager elm]

When you change an asset via code you need to tell Unity to save the changes. EditorUtility.SetDirty(yourSO);

[summer stump]

Is health private?
You could use [SerializeField]

[polar acorn]

Show the inspector for HealthManager

[ionic zephyr]

it is assigned

[polar acorn]

Then you have a different instance of the HealthManager script where it is not assigned

[summer stump]

Type t:HealthManager into the hierarchy search bar

[ionic zephyr]

yess i found it

thanks a lot

[hearty gorge]

Yeah i do that - theres a save button in my editor that calls

[eager elm]

ah ye, constructors don't work for MonoBehaviours and ScriptableObjects

[hearty gorge]

gotcha, how best to initialise the list? Just check if its null in my editor before accessing it I guess

[wintry quarry]

If you look at the basic examples for custom editors there's some bookkeeping I believe oyu're missing:
https://docs.unity3d.com/Manual/editor-CustomEditors.html

i.e. the serializedObject.ApplyModifiedProperties(); bit

notably you're doing the SetDirty part before rendering the tiles list

[eager elm]

I don't use auto properties but if you write it out fully you can say:
[SerializeField] private List<Tile> tiles = new List<Tile>();
And it will never be null

[hearty gorge]

yeah fair - I did try that first and when it wasn't working moved to a constructor - will revert to that

[hearty gorge]

That at least gives me something to look into - thanks

[hearty gorge]

not sure what you mean by this part though - the SetDirty is only called from a button press in the editor

[eager elm]

I think that's also why it reset, because the field isn't actually serialized.

[ionic zephyr]

it exits the IENumerator before executing the 2s wait time, I dont know what to do

[wintry quarry]

right exactly - you need to do the applying of changed serialized data constantly with the ObjectField stuff. Realistically this direct manipulation you're doing of the object is not best practice. In an editor you're supposed to interact with the serialized objects through thte SerialzedObject API and then applying the changes

[hearty gorge]

I see, I figured I was probably doing something wrong in the manipulation for it to be doing this weird persists during session but not on editor restart thing

[eager elm]

When the gameObject that runs the Coroutine gets destroyed the Coroutine will stop as well

[hearty gorge]

I kind of want to only set dirty at the end though, since later down the line I want to validate some basic rules on whats been edited before saving it

rather than each time a property is changed

[ionic zephyr]

but in my script it doesnt get destroyed

oh okay

nevermind

[summer stump]

Did you figure it out?

[ionic zephyr]

yes bro thanks a lot

[hearty gorge]

serializedObject comes from inheriting Editor right? I'm inhereting EditorWindow and getting to the scriptedobject asset via a EditorGUI.ObjectField being populated, so I don't think I have access to that?

[ionic zephyr]

however now i have to figure out how to make the object dissapear whenever it touches the ground without not making the wait time to occur

[wintry quarry]

you can wrap your ScriptableObject in a SerializedObject in OnEnable and use it:

SerializedObject serializedTarget = new SerializedObject(mySO);```

[hearty gorge]

Ah cool thanks, ill try going that route

[eager elm]

disable the spriteRenderer on it

[ionic zephyr]

oh really? but then the instant is still there

and it lags the hole thing

[warped ibex]

Can anyone tell me why my second slider is not updating the value placed on it? Follow the prints.

[summer stump]

Not sure what you mean. Disabling the renderer would be near instant. It'd SHOW on the next frame, but the command wouldn't lag anything

[ionic zephyr]

isnt the excess of gameobjects a cause of lag?

[summer stump]

Maybe, maybe not. You can have a lot of gameobjects. Always profile

Creating and destroying is more costly than enabling disabling usually. To an extent

Which is the justification for pooling

[ionic zephyr]

Oh ok, my god im learning a lot today xdxd

thanks again

[wintry quarry]

This is a mess. Just directly reference these things in a script on the telaEditar object and simply call a function on it

you shouldn't be reaching deep inside other objects like that

and you can't rely on any specific ordering for GetComponentsInChildren

[novel shoal]

@summer stump the course doesn't have what you call "non primitive data types"

i got to methods, and after them there is only OOP

[summer stump]

It does. It talks about classes and structs

Non-primitive Types is what I said

[novel shoal]

so those are OOP?

[summer stump]

And it's a phrase I made up on the spot to just mean anything other than primitive types

[summer stump]

No

OOP represents a programming architecture. It uses inheritance and abstraction

[novel shoal]

i'll go on with the course and figure out on my own lol

[novel shoal]

and classes?

[summer stump]

No. Classes can be used in OOP and compositional architectures.

[novel shoal]

okk

[summer stump]

Classes are an example of a TYPE though

[novel shoal]

i thought they were cuz when i did the python tutorial, the guy said "we'll be talking about object-oriented programming"

[summer stump]

You use classes in OOP for sure.
You make a base class, you inherit from it to extend the behaviour, and bam, that's OOP.

But you also don't have to inherit. You can make each class do a small part and just combine them to make a cohesive and modular whole. Bam, that's composition

[visual delta]

Why can’t i drag a script into my player prefab

[novel shoal]

okk ty

a question

if "function" are called "methods" in c#, how are the "methods" (the ones followed by the dot) called?

[eager elm]

you can't add script from the scene unto objects in your Assets

[eager elm]

members

[summer stump]

Methods are just functions that are in a class or struct
Not sure what you mean by the ones followed by a dot.
If you mean dot notation, it's just how to access members (whether those are fields or methods themselves) as gruhlum said

[novel shoal]

okok

in python they were called methods so i was confused

[summer stump]

They are called methods in c# too

[novel shoal]

but methods are function

[summer stump]

Same as python

I use python too btw. Quite extensively

The difference between a method and function is scope

[novel shoal]

ok?

lol

it's obvious that if i don't study i will be confused

my english sucks tho, sry

[summer stump]

No you're fine! Nothing to worry about

[unreal phoenix]

Not sure how to stop the value boxes from appearing to the side like that. Or how to configure the massive gap

[eager elm]

what type of field is this?

[unreal phoenix]

It's a PropertyField

[tacit grotto]

Can a static Rigidbody gain velocity?

[summer stump]

No

[wintry quarry]

no

https://docs.unity3d.com/ScriptReference/RigidbodyType2D.Static.html

This type of Rigidbody2D should never repositioned explicitly. It is designed to never move.

[tacit grotto]

What if I constantly set it's position to another gameobject, which is moving?

[summer stump]

Then it is teleporting with no velocity
At each position, it is not actually moving. It is just set to a new non-moving position

But really, why move a static rigidbody?

[green copper]

If I use the I key to run the function changeAspectToClassic() in the camera script, everything functions as intended.

If I use the menu to run the same function from the main game manager script, the selector arrow, which is a TMP, becomes misaligned with the rest of the menu until the meny is closed and reopened

the function in question

[wintry quarry]

What does RescaleCamera() do?

[green copper]

it's the function that adds letterboxing

Here's the whole aspect ratio handling script

and, as may also be relevant, all menus are on their own canvas, and the selector arrow is on its own dedicated canvas so it can be shared between all menus. All elements on menu related canvases are anchored to the center of the screen

[eager elm]

how do you move the selector arrow?

[green copper]

https://gdl.space/izigupelus.cpp

here's the up function, down is identical but in the other direction

it gets the Y axis position of the targeted menu element, which exist in arrays

[eager elm]

Do you call this every frame?

[green copper]

no, it's only called when either directional button is presset while paused and with an active menu
