1. you will need a VR headset - there's a bunch of tutorials for getting it set up to be recognised in Unity, do this in an empty project so you can test what you make
2. look into the XR Interaction Toolkit package - it's Unity's out-of-the-box solution for XR input and interactions, and can be a starting point for understanding how VR input works

otherwise it's mostly overlap with standard C# and Unity concepts - the only real difference is a very different way of processing input

Quick question, do IPointer Events handle rotations well?

e.g if an object is constantly slowly rotating, does it still register IPointerEnter properly?

[leaden ice]

why wouldn't it?

Apparently I cannot build any project, can anybody help me?

[slow crag]

I've got a bit of a tough problem that I'm not sure how to approach. When my perspective camera is angled down, I grab screen positions of the 4 corners and project them onto the world. I need to find all regions inside of those 4 corners. Regions are just sets of 12x12 tiles.

I could draw a straight line from each corner,, see what tiles that line crosses and get the edge regions like that, but how can I get the center regions?

For example, the region in the center (111) isn't touching any corners, but I still need to check if its inside
This will be checked basically every frame and will be used for a system to cull the shadows outside of the player's view to improve performance, so this should be as fast as possible

They were like reinstalling the hub, the version, Disabling Development builds, Changing the IL2CPP Code Generation to Smaller (Faster) builds, changeing the Managed Code Stripping level in the player settings to a higher value

Or even deleting Bee folder

What's the next best thing to a null Vector2? I want to declare it but don't want to initialize until I check if it's null in Awake(). If it's not I want to leave as is

[woeful leaf]

Vector2.zero

[swift falcon]

Aight thanks

[lucid valley]

Vector2 cant be null unless you make it nullable, so either use Vector2.zero or make it nullable private Vector2? vector = null;

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

[swift falcon]

The "?" is what does it?

[lucid valley]

makes it nullable

[swift falcon]

Oh great

[lucid valley]

value types by default cant be null, but you can make them be able to be

[swift falcon]

Makes it better. Will avoid possible hiccups. Thanks

[swift falcon]

I have GameObject.FindGameObjectWithTag("Player").transform.position = CheckPoint.currentCheckPointPos;
currentCheckPointPos is my Vector2. Without the question mark it works as intended but with it, it gives me an error that it can't be converted to Vector3

[lucid valley]

CheckPoint.currentCheckPointPos.Value; if you are 100% it can't be null at that point, otherwise null check it before or else you will error

[swift falcon]

I got an if right before that assigns it a value. And thanks 💯

[ember cedar]

why my player following script for enemy doesnt work

[warm wren]

There's no variable named 'Player' in your MeleeEnemy script

[halcyon nimbus]

looks like it inherits

[warm wren]

oh wait nvm

[ember cedar]

but i access it from Enemy

[lucid valley]

just fyi if you don't need the variable in the inspector and need it in the inherited class you can use protected rather than public and [HideInInspector]

[ember cedar]

oh thanks

[halcyon nimbus]

how does Start method work with inheritance?

especially if its private

[lucid valley]

it follows the top most class, otherwise you'll need to make it virtual and override and call base

public class Base : Monobehaviour 
{
    public void Start()
    {
      Debug.Log("0");
    }
}
 
public class Inherit : Base 
{
    public void Start()
    {
      Debug.Log("1");
    }
}
 
public class LastInherit : Inherit 
{
    public void Start()
    {
      Debug.Log("2");
    }
}

e.g "2" will be the only thing printed in this example

[vague slate]

I'm looking for a way to have some callback on play mode stop. Is there a way to do so?
I tried this, but no OnDestroy is called for this game object for some reason

                var disposer = new GameObject { hideFlags = HideFlags.HideInHierarchy }
                    .AddComponent<CustomSourceDisposer>();

[ember cedar]

changed it to public and still not working

[lucid valley]

do you know how to use breakpoints?

[ember cedar]

no

programming isnt my strongest side

[halcyon nimbus]

what if LastInherit didnt have a Start method of its own?

[lucid valley]

good time to learn, https://www.youtube.com/watch?v=d0815qbx3BA

[lucid valley]

then it'll be "1" i think but i'm not sure if i've ever tried it

[ember cedar]

ill definietly check that out

[halcyon nimbus]

Did a test. Checks out.

[lucid valley]

good to know

[zinc parrot]

so I havent touched native plugins yet, but I want to for one reason: bindless textures
so I am wondering if there is a way to pass a compute shader from unity to the native plugin, have the plugin assign a bindless texture array to the compute shader, and then unity run the compute shader?
I am having a hard time finding what is exposed to native plugins

[swift falcon]

Does drawing over a tile using the 2D TilePalette replace the tile or does it add a layer?

[potent sleet]

drawing over tile?

[potent sleet]

you need to add another tilemap to "draw" ontop

or it replaces it

[swift falcon]

Ok ok

Thank you 🙏

[digital gull]

OnFoo += Bar; OnFoo += () => Onfoo -= Bar;

is that a valid way to make sure I unsubscribe to the event right after the event happens?

I mean it works I'm just worried it's bad practice. For example if the event delegates get calld in not the subscribed order

[mental rover]

the anonymous delegate wont be unsubscribed this way

I'm not sure if that would manifest as a problem depending on use though

[digital gull]

wdym? I believe it does unsubscribe, btw Onfoo is typo, should be OnFoo

[leaden ice]

Unsubscribe inside Bar

[digital gull]

that makes sense

[leaden ice]

Note that this leaves the lambda still subscribed even though Bar isn't

[mental rover]

you are subscribing two things with this code, and unsubscribing one of them

[digital gull]

ahh i see

still wrapping my head around lambdas, thanks for the heads up

i thought the content of the lambda was OnFoo -= Bar

oh nvm

i think i see what you mean. the lambda isnt being unsubscribed

[leaden ice]

And it never can be since you don't have an independent reference to it

[digital gull]

right the unsubscribe event isnt being unsubscribed too heh. xzibit moment

[tawny jewel]

hi, so im really hoping someone could help me. so im basically making a floppy bird and trying to spawn a powerup with code provided below, but obviously i dont want it to spawn in the view of camera, or behind the player. so im trying to make it spawn only if x axis if center is bigger than 20, and if it isnt, instead of wasting the timer, i want it to wait a while until next set of pipes spawn and generate the new center and powerup there instead. ive tried coroutine and invoke repeating and both just ended up breaking unity. any ideas, tips how i can achive the desired effect in the easiest way?

the code:

Instantiate(revivePowerup, center, Quaternion.identity);```

[ember cedar]

is this supposed to take over 30 minutes or did i do something horribly wrong

[lucid valley]

try reattaching to the unity editor in your IDE

sometimes it does seem to get stuck

[ember cedar]

well this window disappeared but my project is still frozen and i dont wanna close it because i didnt save it in like 4 hours

[potent ridge]

I have a question regarding the Line Renderer. I use the Line Renderer for a Power Indicator, to show how much power you're applying atm by multiplying the length of the Line Renderer. Though, this issues a problem, since sometimes if I am too close to a wall, and I try to shoot to the left, the indicator would go through the wall. This is not what should happend. How can I manipulate it so, the line is visible at all times, without it going through walls?

https://media.discordapp.net/attachments/763495187787677697/1067875747877892126/image.png

https://media.discordapp.net/attachments/763495187787677697/1067875909174042797/image.png

I tried using different layers, but when adding a new layer, and assigning the indicator to that layer, the line renderer still goes through the wall

[lucid valley]

have you put down a breakpoint in the update? That will freeze it every frame, so just remove it and press the play button in you ide. There should also be a supress breakpoints button which you can also toggle on

[covert shard]

hi there, i have a problem with the code and functionality of ads. basically, the ads button works well for the first time i enter the game over scene, but when i play again and die and come back to the scene, the button just doesnt work and doesnt show ads anymore, can anyone help?

[tawny jewel]

this is still unresolved, just saying

[mossy snow]

use a coroutine, but use it correctly this time

[tawny jewel]

thanks that changes everything

[mossy snow]

I'm not sure what you expected, coroutine would be the simplest solution but you didn't provide whatever code you tried with it so there's not much more to say

[tawny jewel]

sure, i can provide what ive tried so far
so heres the coroutine way

  {
      Vector3 center = Vector3.Lerp(pipespawnscript.lastpipe.transform.position, pipespawnscript.secondPipe.transform.position, 0.5f);
      if (isPowerupInstantiated == false)
      {
          StartCoroutine(RevivePowerup());
          Debug.Log("coroutine started for revive");
      }
  }

  IEnumerator RevivePowerup()
  {
      while (true)
      {
          Vector3 center = Vector3.Lerp(pipespawnscript.lastpipe.transform.position, pipespawnscript.secondPipe.transform.position, 0.5f);
          if (center.x > 10) 
          {
              Instantiate(revivePowerup, center, Quaternion.identity);
              isPowerupInstantiated = true;
              setRandomReviveTime();
              Debug.Log("instantiated revive");
          }
          yield return new WaitForSeconds(1f);

      }
  }

} ```

[mossy snow]

your coroutine never yields, so you have created an infinite loop that will freeze Unity

[tawny jewel]

oh sorry wrong code

[ember cedar]

not the game froze but the whole project

i cant even minimalise it

[tawny jewel]

i edited the message now its good

[mossy snow]

the way you are doing this is weird. I assume it's the pipes that move and not the player. Since you never end the coroutine in this code, I would at least assume that more and more revive powerups are getting spawned if the pipe locations are accurate and moving

[ember cedar]

i restarted it and it somehow auto saved so nvm

[covert shard]

?

[tawny jewel]

yes the pipes move, i have a timer that just spawns the revive every so often

if it hits 0 the revive powerup should spawn, but it would sometimes spawn behind player with just two lines of code so i basically tried to prevent this

[wild vigil]

How do I link a file through code from assetdatabase?

[mossy snow]

that sounds like something is wrong with your pipe positions, then. Debug the spawn location. Also end the coroutine after spawning something

[tawny jewel]

alright, i ll add a couroutine ending, tho im not sure if its the pipe spawning issue. the next set of pipes just isnt generated yet, so it spawns the powerup at the only avaible center, with at some times is in the camera view already. i assume i could fix that by just moving the pipe spawner, but that will result in player waiting ages at the start of the game before the pipes get to him

[digital gull]

` int x;

void Main()
{
    x = 0;
    OnFoo += Bar;
    x = 1;
    OnFoo(); //prints 1
}

void Bar()
{
    Debug.Log(x);
    OnFoo -= Bar;
}`

Is there a way to subscribe to an event with specific current value and not the value when the event is called?

I know I can do OnFoo+= () => Debug.Log(x)

But I am trying to subscribe a method with the values of variables on time of subscription

My option is specifying the parameters of my delegate and inputing those but I'm trying to make my delegate parameterless and handle different logics inside.

` int x;
string s;
void Main()
{
x = 0;
s = "foo";
OnFoo += Bar;
x = 1;
s = "bar";
OnFoo += FooBar;
OnFoo(); //prints 1,bar. hoping to get 0,foo

}

void Bar()
{
    Debug.Log(x);
    OnFoo -= Bar;
}

void FooBar()
{
    Debug.Log(s);
    OnFoo -= FooBar;
}`

[devout nimbus]

Does Unity still not support default method implementations for interfaces?

[valid minnow]

im getting this error for this line of code and idk why, tbh i dont really understand what it means, can i get some help?

[proper oyster]

null reference means that you are trying to acess some object that is not set
in line 55 it could be that the Collision2D value does not have a rigidbody or a sharedMaterial

[valid minnow]

i have a tilemap im using for collision, and it had a tilemap collider, could that be why im getting an error? and if so, how do i fix it?

[proper oyster]

you might want to check if
collision.Rigidbody is not null before using it

[valid minnow]

how so

[proper oyster]

like you do with the _material below

[valid minnow]

should i just do debug.log?

[proper oyster]

if you are intereted in the result you could
but if you cant be sure that a value is set make sure that your code only is run when the values is not null

[valid minnow]

it loos like the value isnt null when i ran the game

[valid minnow]

ok

like this?

ohh that fixed it:)

welp

now i have a new issue

when i export and build the game the player falls through the ground. but when i test the game inside of unity nothing like that happens, idk why

@proper oyster

[proper oyster]

i dont know
i know noting about your scene or setup

[valid minnow]

idk how to fix it tho 😢

i do get this tho

maybe that has something to do with it?

[valid minnow]

idk really know either lol

[kindred pollen]

Sooo, no one able to help me? D:

[dusky spear]

will collider2d.overlapcollider return tilemap colliders or no?

[leaden ice]

yep, all 2d colliders

[dusky spear]

huh

cuz im doing thisCollider2D[] colliders = {};
lightArea.OverlapCollider(filter, colliders);

Collider2D[] colliders = {};
lightArea.OverlapCollider(filter, colliders);

and not getting shit

even tho the shape is big enough to be overlapping a tilemap collider

[leaden ice]

you've given it an empty array

an empty array has no space to store any results

The size of the array determines the maximum number of results that can be returned.

[dusky spear]

ohhh

is there a way to not limit the number of results?

[leaden ice]

Maybe you want to use the List version?

[dusky spear]

ah ye

does unity have its own version of lists or do i just use c# lists

or do i want to use arraylist or smthn

[leaden ice]

C# list

[dusky spear]

ok

[hard sparrow]

Why doesn't this work?

[leaden ice]

I mean just look at the docs

https://docs.unity3d.com/ScriptReference/Collider2D.OverlapCollider.html

the second one takes a list

[leaden ice]

read the error

[hard sparrow]

it doesn't say anything useful

[leaden ice]

sure it does

it tells you why you can't do that

[leaden ice]

what you can do is something like:

foreach (Cell key in _outpostDict.Keys) {
  _outpostDict[key] = _outpostDict[key] + 1;
} ```

[hard sparrow]

this also works apparently

[dusky spear]

cool thx this seems to work but for some reason im getting an error on the list

[hard sparrow]

Don't know why

[leaden ice]

it's a special thing

[leaden ice]

seems like you never initialized the list

[dusky spear]

i used to not be this much of a unity noob but i took a break from a bit

lightArea.OverlapCollider(filter, colliders);
Debug.Log(colliders[0]);```

[leaden ice]

seems more like lightArea is null then

[dusky spear]

????

its set in editor

[leaden ice]

Debug.Log

find out what is null]

[leaden ice]

oh this error

is from the Unity editor code

it's not your code

[dusky spear]

oh ok

[lucid valley]

one of the nice things about the upcoming .NET switch is that this is valid since .NET 5

foreach (KeyValuePair<string, int> pair in dict)
    dict[pair.Key] = pair.Value + 1;

don't need to loop through just the keys and do the extra lookup for the value, i always forget to do it and then wonder why it errors

[dusky spear]

ah yeah i restarted unity and it went away

i think i accidentally compiled while game was running

and it didnt like that

[hard sparrow]

So if I wanted to modify the Key now, I'd have to make a copy of the key, modify that, then replace old key with new key?

[leaden ice]

you can't modify keys in a Dictionary really

well, only if the modification doesn't change its definition of Equality

But it really just depends on if the Cell type is a class or a struct

[hard sparrow]

It's a class

[leaden ice]

then you don't need to make any copies of anything

[hard sparrow]

oh that's right. The thing I wanted to modify is private and I assumed it was because of dict XD

[leaden ice]

yeah I usually turn that feature off, it's useless and just causes errors

[lucid valley]

you sure Cell is a class, from your colouring it looks like a struct (or have you got classes and structs the same colour?)

[hard sparrow]

Oh well it's a struct composed of classes. So... a struct actually XD

[leaden ice]

... well that means you need to make a copy then

unless the modifications are to the classes the struct is referring to

and not the struct itself

[hard sparrow]

It's fine, I've got it now 👍

[dusky spear]

what feature?

[timber cloak]

For methodes like Instantiate(), I noticed that it can take in an object as parameters or the object and a parent ect ect, how can I do that to my own method

[leaden ice]

this one

[dusky spear]

ah yeah

[leaden ice]

you just define multiple versions of the method with different parameter lists

usually have them call each other

[dusky spear]

hey at least its better than unreal engine

in unreal if you compile c++ while the editor is open at all

it will possibly irreversably corrupt your entire project

but nothing anywhere tells you that

[leaden ice]

int MyMethod(int x) {
  return MyMethod(x, 5f);
}

int MyMethod2(int x, float y) {
  
}```
For example

[dusky spear]

and there is even a button in editor to do just that thing

but it gives you no warnings when clicking it

[timber cloak]

thank you :)

[leaden ice]

you can also use optional arguments like:

int MyMethod(int x, float y = 5f) {
}```

[leaden ice]

fun

[mental rover]

A few months ago I would've been thinking this can't be true, but I tried out UE recently and it actually is - completely insane that it's got a big compile button in the editor but clicking it seems to have a good 50% chance of corrupting something in your classes

[dusky spear]

yeah

apparently they fixed it in unreal 5 tho

[scenic creek]

Will this cause a compile error when UNITY_EDITOR is not defined in my build?

public class myClass : MonoBehavior
{
#if UNITY_EDITOR
    public int myInt;
#endif
    public void OnDrawGizmos()
    {
         Gizmos.DrawSphere(new Vector3(0, 0, 0), myInt);
    }
}

How does Unity handle OnDrawGizmos? Is it still compiled into the code but never called, or is it compiled out?

[proven plume]

Yes, since myInt won't have been declared

[quartz folio]

It is generally a bad idea to define different serialised values for the editor or runtime, regardless of the fact this also won't work

[proven plume]

Yes, you can get build errors because the serialization no longer matches. It would be better to have this value exposed somewhere else, like in a custom editor where it doesn't get serialized.

or in some custom project settings

[scenic creek]

Thanks

[mossy snow]

you didn't test that at all, did you?

[outer nimbus]

I tested it

And it kinda work but the whole game like stops

I forgot to delete the Destroy bullet, but it like kinda works but the whole game freezes.

SO i still need help

[mossy snow]

its previous behavior would've been: press the shoot button to freeze the game for 5,005ms and the bullet travels nowhere, so I'm not sure about the kinda works part. Don't put the main thread to sleep. Use coroutine to delay. Move your nested coroutine out of that method. Keep track of the last time you shot, and don't shoot again until enough time has passed

[outer nimbus]

Could you send the fixed code for me if you can? You dont have to but im a bit new but still not really a beginner.

[leaden ice]

Never ever use Thread.Sleep

Why is there a sudden influx of people doing that 🤔🧐

[weak spoke]

When do tags get loaded in?

[leaden ice]

Wdym by that

[weak spoke]

Are they loaded in before the awake func

[leaden ice]

Yes

[weak spoke]

ie can i use them in there

weird

[leaden ice]

Why

[weak spoke]

so im making a table and for some reason it's not setting it

[leaden ice]

A table?

[weak spoke]

hashtable

[leaden ice]

Setting what?

Show your code and explain what you're trying to do

[weak spoke]

private void buildPanelTable()
    {
        for(int i = 0; i < 4; i++)
        {
            GameObject panel = GameObject.FindGameObjectWithTag("PlayerDemon" + (i + 1));
            if (panel.activeSelf)
            {
                Demon demon = panel.GetComponent<PlayerDemon>().demon;
                demonToPanel.Add(demon, panel);
            }
        }

        for (int i = 0; i < 4; i++)
        {
            GameObject panel = GameObject.FindGameObjectWithTag("EnemyPanel" + (i + 1));
            if (panel.activeSelf)
            {
                Demon demon = panel.transform.parent.gameObject.GetComponent<EnemyDemon>().demon;
                demonToPanel.Add(demon, panel);
            }
        }
    }

this gets called in the awake

[leaden ice]

What is demonToPanel

[weak spoke]

thats the dict <Demon,GameObject>

[leaden ice]

GameObject panel = GameObject.FindGameObjectWithTag("PlayerDemon" + (i + 1));``` this is super fucking weird tbh

why are you doing it this way

why don't you just assign the references in the inspector

This requires you to make a whole bunch of tags

and do string concatenation, which is slow and creates garbage

[weak spoke]

I thought dict didnt work with inspector

[leaden ice]

it won't

[weak spoke]

thats getting called once

[leaden ice]

make a list of a struct containing the key/value pairs

populate the dictionary from that

or just two arrays/lists

[weak spoke]

Yeah ill just do that

[leaden ice]

possibly your code was failing due to FindWIthTag's inability to find inactive objects though

[weak spoke]

oo

yee

thats probably it

[unreal temple]

Does anyone know what is meant here?

On Windows, use -logfile - <pathname> to direct the output to stdout, which by default is not the console.

Is it literally suggesting Unity.exe -logfile - <pathname>

What would pathname be for stdout??

-logfile - stdout?

[leaden ice]

I believe 1 would be stdout

but not totally sure

[unreal temple]

Could you show me an example?

[leaden ice]

-logfile 1```

[unreal temple]

so the docs are just confused?

[leaden ice]

Maybe?

oh I see what you mean

[unreal temple]

I mean what on earth does "On Windows, use -logfile - <pathname> to direct the output to stdout, which by default is not the console." mean?

[leaden ice]

yeah I have no idea lol

[unreal temple]

still nothing

Well, not nothing

[leaden ice]

rofl

what about &1?

[unreal temple]

I'm doing this through git-bash

[leaden ice]

-logfile &1 I mean

[unreal temple]

I think that's trying to run command 1 in a new process

[leaden ice]

indeed

[weak spoke]

@leaden ice so the issue was that in the awake i was calling priv funcs

[leaden ice]

calling private functions in Awake is not a problem

[weak spoke]

this is so weird, im doing 2 arrays and then building the table

and still null

[leaden ice]

what is null

show

explain

[weak spoke]

ye one sec

[SerializeReference] public GameObject[] demonToPanelPanelPlayer;
[SerializeReference] public GameObject[] demonToPanelPanelEnemy;

[leaden ice]

why use GameObject[]

[weak spoke]

i put everything into the inspector

[leaden ice]

why not Demon[]

also why SerializeReference???

wat

[weak spoke]

Demons a SO

[leaden ice]

so?

Then you definitely don't want GameObject

you want Demon

[weak spoke]

Demon is a field in a script

[leaden ice]

also how can one array represent "demonToPanelPanelPlayer;"

when I said two arrays I meant like this:

[SerializeField] Demon[] keys;
[SerializeField] GameObject[] values;```

then you do:

for (int i = 0; i < keys.Length; i++) {
  myDict[keys[i]] = values[i];
}```

note that you don't need public and it's [SerializeField] not [SerializeReference]

[weak spoke]

ye that was a typo

the demons get loaded in from another scene

how would i put the demons that will be loaded in the panels into the list through the inspector

[leaden ice]

I thought you said demons were ScriptableObjects

[weak spoke]

they are

[leaden ice]

I guess I don't fully understand what's going on here

you'd have to share more of your code

Also you didn't explain what exactly was null and where

and how it had been assigned

[weak spoke]

Thats a script, demon is a SO

[leaden ice]

It is? If it was an SO it would appear as a refernece here

not a foldout

unless you're doing some custom editor scripting

by "SO" do you mean "plain old C# object" / POCO?

[leaden ice]

as in - a class that doesn't derive from MonoBehaviour?

Yeah that's not an SO

That's just a regular class

SO means ScriptableObject

[weak spoke]

oo ok so tech my db is the so

[leaden ice]

DemonDatabase is an SO

[weak spoke]

ok ok

[leaden ice]

but here it looks like your PlayerDemon script has a Demon field directly

it's not using DemonDatabase

[weak spoke]

so before the scene with all of that

i drag and drop from the db

[potent sleet]

bruh..

[weak spoke]

and then from the first scene into that scene it will loaded it in

[leaden ice]

you are trying to map what to what here with your Dictionary?

[weak spoke]

So all this gets saved from dontdestory once the first scene is done (a random encounter occurs)

and thats where those get populated from

[leaden ice]

the EnemyParty script?

gets populated by demons from DemonDatabase?

is that what you're saying?

[weak spoke]

WorldScene starts first

nothing in battle is loaded in

after some steps in the 3d world, it will load in the battle scene

(ignore that its loaded atm in the inspecotr)

[leaden ice]

^?

[weak spoke]

Yes

Both the player and the demon party does

[leaden ice]

ok so again - what is the Dictionary you are trying to make here?

mapping what to what

[weak spoke]

So i want to be able to know the panel of x demon

So given a demon, i want to know its panel

hence the mapping from demon to go

[leaden ice]

shouldn't you be doing something like this?

GameObject[] panels;

void PopulatePlayerPanels(List<Demon> playerDemons) {
  Dictionary<Demon, GameObject> panelMapping = new();
  for (int i = 0; i < playerDemons.Count; i++) {
    Demon playerDemon = playerDemons[i];

    // populate the UI planel
    panels[i].GetComponent<MyDemonPanelScriptOrWhatever>().Initialize(playerDemon);

    // Establish the mapping
    panelMapping[playerDemon] = panels[i];
  }
}```?

Though again I wouldn't use a GameObject[], probably an array of the UI script on each panel (which I called MyDemonPanelScriptOrWhatever in this example)

Now you need to be really careful here because if you're not creating copies of these demons, you have a bunch of references to the same demon object all over the place

[weak spoke]

public class EnemyDemon : MonoBehaviour
{
    [SerializeField] public Demon demon;

    private void Start()
    {
        int idx = transform.GetSiblingIndex();

        if (BattleManager.Instance.enemy.enemyParty.Count > idx)
        {
            demon = BattleManager.Instance.enemy.enemyParty[idx];
            transform.gameObject.GetComponentInChildren<Image>().sprite = demon.demonImage;
        }
        else { transform.gameObject.SetActive(false); }
    }
}

heres how the demons get loaded in to the panel

[leaden ice]

so not only with this Dictionary not really work, but you'll be changing the HP of all demons who share that reference etc, including the Database

[weak spoke]

ye i realized that a a bit today, i just started learning unity like a week ago

[leaden ice]

yeah you're doing this in each individual UI panel, instead of just having a script loop through these panels and populate them

[weak spoke]

im just gonna use initaite func whenever i pull them in from db

[nimble dome]

Does anyone know why in the world this code makes the game object flicker randomly and fast? I don't work with coroutines often so i feel like i might be missing something obvious...

    {
        WaitForSeconds wait = new WaitForSeconds(markerFlashSpeed);

        while (!trackingPlayer)
        {
            destinationIndicator.SetActive(false);
            yield return wait;
            destinationIndicator.SetActive(true);
            yield return wait;
        }
    }```

[weak spoke]

idk 2 me this felt more natural idk

ig one issue could be the load order of scripts

[leaden ice]

where and how are you starting the coroutine? Are you starting it in Update?

[nimble dome]

yep so I was missing something obvious. I think i might have been too sleep deprived last night to realise i was calling the function many times over. my bad 😂

forgot to set a variable to true which would stop that.

[weak spoke]

something weird is going on lol

private void buildPanelTable()
    {
        foreach(GameObject x in demonToPanelPanelPlayer)
        {
            demonToPanels[x.GetComponent<PlayerDemon>().demon] = x;
        }

        foreach (GameObject x in demonToPanelPanelEnemy)
        {
            demonToPanels[x.GetComponent<EnemyDemon>().demon] = x;
        }
    }

@leaden ice so i put a break point here at the first foreach

and i started stepping in

and when it hit the getcomponent, the game just started running and broke out of the entire loop

[leaden ice]

you probably got an exception

anything in the logs?

[weak spoke]

oh yes i did

[leaden ice]

also instead of doing a GameObject[] just do PlayerDemon[]

[weak spoke]

oki

[leaden ice]

then you don't have to do GetComponent

You can just do demonToPanels[x.demon] = x.gameObject;

[weak spoke]

so like i said before the things get loaded in late

if i copy the component

does it copy it as a ref?

cause atm rn its empty

until the first scene is complete

[leaden ice]

huh

it's the same as doing the GameObject

just with a direct reference to the script instead

[leaden ice]

copy what component

[leaden ice]

define "component" here

[weak spoke]

the playerdemon

[leaden ice]

the only thing here that is a Component is the PlayerDemon script itself

yes

[weak spoke]

so that gets loaded in

[leaden ice]

wdym by "copy the component"

[weak spoke]

if i copy it and paste it 2 the field in the manager

[leaden ice]

you mean drag and drop?

[weak spoke]

yes

[leaden ice]

it's a reference

[weak spoke]

okay wanted 2 make sure

[leaden ice]

also those type mismatches are just because we changed the type

just drag it in again

[weak spoke]

ye

[swift falcon]

How can I make player movement not freeze when loading chunks?

[leaden ice]

I mean are you sure it's player movement freezing and not... your entire game?

[swift falcon]

Oh yeah it's the entire game

[leaden ice]

loading chunks
You'd have to revisit your technique for doing this and optimize it

make it asynchronous wherever possible, etc..

[weak spoke]

im losing my sanity

[swift falcon]

I have a loadchunks method
There's a dictionary with all chunks, logged with their vector2 locations
void LoadChunks()
{
//add the nearby chunks with a roundOff method to a loaded chunks list. If it doesn't exist in the dictionary, create it

//Loop through the loaded chunks list and if a chunk is too
far, unload it. After removing far chunks, load the chunks in the list that are unloaded
}

[swift falcon]

what's asynchronous

[leaden ice]

very light on details here

explain how you do "loading" and "unloading"

[leaden ice]

asynchronous means doing it in the background while the rest of the game runs.

[swift falcon]

Methods in chunk class

void Unload()
{
gameobject.setactive(false);
isloaded= false;
}

You can imagine the reload one

[leaden ice]

so you're not loading anythingf

you're jsut activating/deactivating?

How do the chunks get spawned in the first place?

[swift falcon]

I already said this, but
If the chunk doesn't exist in the dictionary, aka hasn't been generated yet, it instantiates a new one

[leaden ice]

cool share that code

also for any performance problem, you need to pull out the profiler

[swift falcon]

I'm away from my computer i tried to sum it up

[leaden ice]

It could be the Instantiate itself that is slow, it could be generating the data for it. It could be a script in Awake or Start doing something slow etc...

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

You have to profile it

then you'll know where to look to optimize it

[swift falcon]

It uses a double for loop that starts at -renderdistance and ends at +renderdistance

[weak spoke]

its gotta be a load thing

[swift falcon]

Then it rounds off a chunk position and if it doesn't exist, it generates it

GenerateChunk

[leaden ice]

profile it

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

[swift falcon]

ok

will that help me make it faster?

And how to make something async

[leaden ice]

it will show you which part of your code is slow

then you will know what to focus on

[weak spoke]

@leaden ice cs has a default hash func right

[leaden ice]

depends what you mean

every object has a GetHashCode and object has a default implementation of it

which more or less corresponds to object identity

[weak spoke]

And these objects are == if they're at the same address?

[leaden ice]

if it's a class, yes

not if it's a struct and not if you've overridden == for your specific type

[weak spoke]

Ye so that can't be the issue

[leaden ice]

do note that when you serialize things, it can get weird

unity may be breaking the "sameness" of the objects

[weak spoke]

When do u want to serialize vs just set to public

Before I started I thought I needed to serialize to have the field active in the inspector

[leaden ice]

making it public serializes it

[weak spoke]

Seems like just public does it

Ah ok

[leaden ice]

yes, making it public causes it to be serialized

[weak spoke]

im just going to make a public dict

and have the panels reach in and add themselves

kidna feel stupid i didnt do that from the start

yeah its good now

all the panels had a depedence on the battlemanager, and then the battlemanager needed a dependence from the components for the table so ofc it would shit itself

[fleet fern]

while making a game with a snake ai, I ran into an issue with the segments' scripts reacting only once every couple of frames. I assume with has something to do with too much running at once, but there aren't too many other scripts running. Is there a potential other reason for them lagging behind?

[leaden ice]

Are you using FixedUpdate? It doesn't run every frame

[fleet fern]

I was, then switched to update, and it continued to happen

[leaden ice]

well how do you know the scripts are only "reacting once every couple of fframes"

what do you mean by that

Update runs every frame, no matter what

the gaps you are seeing are probably due to something in your code, like assuming frames land on perfect even boundaries of time or something

it's actually kind of tricky to get snake right

[fleet fern]

the only code I have running for the segments is this

I'm not sure if that would require something too strenuous

[leaden ice]

stop thinking about "strenuous"

this isn't a performance problem

it's a math/logic problem

[fleet fern]

yeah, I just realized it

[leaden ice]

that position calculation looks pretty sketchy

[fleet fern]

it's a bit messy

apparently somewhere the size got set to 10, making them react only a tenth of the time

ty though

[weak spoke]

@leaden ice btw since i dont want a SO for my demon db, i should use a prefab right?

cant tell what i want lol, sorta need a place where i can just make some demons in and drag and drop, but need copies of them

[quaint rock]

if its just something you want to reference SO

if its something you want to have in the scene Prefab

[weak spoke]

gotcha, so i should make my demons prefabs

and then i can make my db a normal class that has a list of demon prefabs

[swift falcon]

I just found out about UShort in C#. Do you guys ever use it often? It’s basically just an empty data type

[leaden ice]

very rarely. WDYM by "empty data type"? It's a numerical primitive struct in the same vein as int long uint ulong short, byte

[swift falcon]

I worded it quite wrong I think

“Holds unsigned 16-bit (2-byte) integers ranging in value from 0 through 65,535.”

[leaden ice]

mhmm, just a basic numerical type

[swift falcon]

Unassigned integers is what I should of said

Yeah

I don’t think it’s that useful I guess?

[leaden ice]

uint, ulong, byte etc also exist

It'd mostly be useful for applications where bandwidth or memory are limited and you have a value you can fit in that type, such as in networking or when dealing with large arrays to cut down on memory usage

[swift falcon]

Oh yeah I see

Cuz in this example they use UShort to store triangles

https://docs.unity3d.com/ScriptReference/Sprite.OverrideGeometry.html

[leaden ice]

yeah it makes sense there because there's a vertex count limit of ~16k for Meshes anyway

so ushort is plenty to hold a vertex index

[swift falcon]

So basically If you need very big arrays it could be good

[swift falcon]

And this type of thing

Well thank you

Very much for explaining

well I still have not been able to find the answer and at this point I also cant find anything what this error could possibly mean

there isnt a lot of info on it

[inner yarrow]

I have tried stuff with portals several times, and in every video I have watched, the camera will make the portal it's behind invisible before taking a picture, and then make it visible again afterwards. I have tried this:

myWormhole.Renderer.enabled = false;
//positioning stuff
cam.Render();
myWormhole.Renderer.enabled = true;

However, it still ends up taking a picture of the portal. Please ping me if you have any ideas?

Also this is being called in Update, not sure if that's causing problems.

[leaden ice]

Can you not simply exclude it from that camera via culling mask?

[inner yarrow]

No, because I idealy want to have recursion eventually, so I don't think that would work.

I must go to bed, so if I don't see someone's answer that's why, but I'll check here again tomorrow.

[next seal]

Feel free to dm me about this

[cosmic rain]

Break that line into several lines. Assign all the fields you try to access to temp variables and use them when creating a new window.

That being said, the error probably means that you hold to the objects through the domain reload preventing the GC from collecting them. Might want to hook to domain reload callbacks, clear the list before it and recreate after.

[slow crag]

I need to check whether some regions of the tilemap are in view of my cameras frustrum when it is angled downwards (2.5D perspective.) This needs to be done every frame and will be used for manual culling.

I'm wondering if it's faster to check if those regions are intersecting with a line, or, if I should compare their bounds to the bounds of the camera with TestPlanesAABB. Intuitively, I really can't tell which would be faster. They're both a bit of math calculation, but it's done every frame so I'd like the faster solution

You're probably having a "compound collider"

dammit dlich to fast

Here they explain about compound colliders
https://docs.unity3d.com/Manual/CollidersOverview.html

[rich nymph]

I spent a good 2 hours trying to figure out why I cannot use IPointerClickHandler in my project, and it seems that the culprit was this specific TMP text object - because after disabling it, the game was recognizing my mouse clicks on all game objects in the game scene. Any idea why that is?

[hasty canopy]

IPointerClickHandler will only work on the object the script is attached to, so if something else is blocking the click , it won't work

In this case i don't know where your gameobject is that has IPointerClickHandler script, but TMP was probably blocking it. You can disable raycast target on TMP and it should work fine without having to disable TMP gameobject entirely

[rich nymph]

hm what do you mean by where my gameobject is, like in the gamescene or in hierarchy?

[hasty canopy]

I don't know which gameobject is using IPointerClickHandler

But Regardless, TMP was probably blocking it

[rich nymph]

Oh it's the SmallTree gameobject that has the IPointerClickHandler, I will look into disabling the raycast target of the TMP object

[rich nymph]

That worked, thanks for helping me understand the issue 😄

[hasty canopy]

Np~

[hasty canopy]

Also for future reference, you can check in event handler gameobject for what is "current Target"

(I maybe misremembering names so bare with me)

That tells you which gameobject is mouse pointing at

[rich nymph]

Oh interesting, I will look into it!

[exotic burrow]

foo ??= new object();

does it have any cons ?

[mellow sigil]

Destroyed gameobjects are overloaded to equal to null but aren't real nulls so any question mark operators shouldn't be used with them

[lucid valley]

nope not for unity objects (gameobjects, monobehaviours, etc...) (It's still fine for normal C# objects)

only using != and == is safe

but you can make it safe by doing something like this

[MethodImpl(MethodImplOptions.AggressiveInlining)]
public static T OrNull<T>(this T unityObject) where T : Object
{
    return unityObject == null ? null : unityObject;
}

Then you can then do this for unity objects and it is safe (but you wouldnt do new for unity objects anyway):

  Object foo = null;
  foo.OrNull() ??= new Object();

Allows you to chain null checks too (not the best example but here's one)

if(FooGameObject.OrNull()?.GetComponent<BarScript>().OrNull()?.ClassThing == null) return;

hello : i need to find the closest point of a collider to a line , i have a method that is already good but it looses accuracy on larger colliders, what would you do to find this closest point ?

[jaunty needle]

How do I generate a random number between 1 and 4 and have it not repeat the same number twice?

[compact socket]

does it have to be not equal to the previous roll or to all other rolls before?

[exotic burrow]

hmm interesting thank you guys

[jaunty needle]

previous

[compact socket]

roll once , save the number in a variable (r) and re roll again, if the second rolled number is == to the saved number reroll again, otherwise save the new rolled number in the (r) variable and repeat

[jaunty needle]

that's...straightforward damn imma try that

[compact socket]

you only output the r value (when it changes )not the actual roll

[lucid valley]

private int lastRandom;

public int GetRandom()
{
      var newRandom = lastRandom;

      while(newRandom == lastRandom)
      {
          //Random.Range for ints is exclusive for the max value, so this will get 1,2,3,4
          newRandom = Random.Range(1, 5);
      }
      
      //Cache for next generation
      lastRandom = newRandom;

      return newRandom;
}

something like that should work

[compact socket]

yes

tho i recommend doing one roll of last random before calling GetRandom() so that you have a starting point

[lucid valley]

humm, this will init on 0 so will always return the first random when called

[jaunty needle]

The while loop simplifies this thank you

[compact socket]

ah fair point , u rite

hello : i need to find the closest point of a collider to a line , i have a method that is already good but it looses accuracy on larger colliders, what would you do to find this closest point ?

[compact socket]

also a do while loop would do

[jaunty needle]

It worked, thanks guys

[left adder]

I really love working on 2.5 D games its really nice in unity 😮

[weary heron]

Hey all, trying to make a procedurally generated island which can be large. I've watched through Sebastian lagues video about it, but I can't seem to make one large island. I have been able to limit the max chunks created, just don't know how to give the outer chunks a falloff map to give the world a border and not a jangled mess. Anyone know what I can do?

[spice aspen]

https://pastebin.com/G894M8Cy
the cooldown is working only one time after that the cooldown is not working any idea why also i have referred the function in update()

[lucid valley]

are you calling Dashcool() somewhere?

[spice aspen]

Yes

Update

Well I actually figured it out i just had to stop the coroutine

[lucid valley]

i'm sure you could combine you Dashing and DashCooling into one coroutine

[spice aspen]

Yes ig but it works so now I m not gonna touch it

[mental rover]

depending on the details of your implementation, you can scale the heightmap by a factor of a function of distance from the center of the island

perhaps a slerp, or a more complex function defined by an animation curve would work well

[tall scroll]

for some reason despite my extremely simple code having public GameObject prefab; as a line, I cannot assign a gameobject in the UI

[weary heron]

Where have you put it in your code, and do you have any errors in the console?

[tall scroll]

public class CopyLightmaps : MonoBehaviour
{
    public GameObject myPrefab;
    public int test;
    // Start is called before the first frame update
    void Start()```

oh yep console errors

someday I will unity correctly istg lol

[weary heron]

That would be the problem then 🙂

[weary heron]

Cool ill try that out

[swift falcon]

I'm trying to clean up my code right now for it to be more readable and make more sense. I've never made a big project before, what's considered good practice? Some people are for comments and others aren't, I know my variables and functions should be self explanatory. Should I also comment my code?

[tall scroll]

ok that fixed it, onto the next channel for my next issue

[winged karma]

Hi all,

When using OnTriggerEnter, how would you identify the object that was hit? The function parameter is the one that triggered the function, but I'd like to point to the object that contains the trigger

[prime sinew]

so the script with OnTriggerEnter is on object A, and object B hits object A. which object do you want to find?

[winged karma]

Object A

[prime sinew]

then it's just gameObject

you use gameObject to get the object that the script is on

[winged karma]

Perfect, thank you

[vagrant goblet]

Hello, I need a prefab x to instantiate new copies of prefab x.

With a regular setup:

[SerializeField]
protected GameObject ChildPrefab { get; set; }

Then plugging a reference to the prefab from the assets folder.

I've noticed that new instances have increasing amounts of x(Copy) x(Copy)(Copy) x(Copy)(Copy)(Copy) with each iteration, as well as same values of its fields. This means that the script doesnt reference the prefab but the instance of itself. Is there any good way to go around this?

[leaden ice]

This means you're copying the copies instead of copying the prefab

You should just copy the prefab

You're doing this prefab = Instantiate(prefab);

You should be doing this:

var newInstance = Instantiate(prefab);

[thorny marlin]

i was just importing an particle asset and it gives me this erro

[vagrant goblet]

The way i instantiate is not the problem here. To prove that, in the OnEnable() function i did this:

if (ChildPrefab == this)
{
  Debug.Log("I reference myself");
}

It feels like a unity bug, ill record a little gif for you sec

[leaden ice]

??? Show the actual instantiation code

And what's this about

This is normal

References internal to the prefab become instance references

This is not a bug

It's intended, expected behavior

And well known

If you want to give the instance a reference to the prefab you'd have to do it after instantiation, e.g:

var newInstance = Instantiate(prefab);
newInstance.originalPrefab = prefab;```

[vagrant goblet]

But if "References internal to the prefab become instance references", then that means I'm instantiatating a copy of the instance and not a copy of the prefab no? The first instance of the prefab already instantiates itself, so this will not work, the code you wrote plugs the first instance as a reference.

[leaden ice]

prefab is a reference to the prefab

Not to the instance

[vagrant goblet]

It isn't though! Thats what im trying to say

[leaden ice]

It is in my example

I'm telling you to put this code on the code that spawns the first instance

Not the script on the prefab itself

[vagrant goblet]

The prefabs spwawn copies of themself, to imitate reproducion

[leaden ice]

Something spawns the first one though

Right

[vagrant goblet]

Ah, i see what you mean now.

So theres no way for me to plug a reference to a prefab inside of the prefab?

[leaden ice]

No because if that worked prefabs would be super broken

You wouldn't be able to have any internal references in the prefab

You just have to assign the reference to the prefab after instantiation, as per my example

[vagrant goblet]

This isn't so easy to do in my case though, I have wrappers that deal with the spawning mechanics, the reproducion script is a really specific meachanics, if I reference that in the initializing script my architecture would go bonkers.

Could I somehow use the Resources.Load() method?

[short timber]

I created an IJob and i have this [ReadOnly] public NativeArray<Vector2Int> availablePositions;.
According to the documentation on package "com.unity.collections@1.4", we have Class NativeArrayExtensions.

Why if (availablePositions.Contains(new(0, 1))) {, Contains method points to System.Linq, instead of recognizing Unity.Collections; ???

The 4th method on NativeArrayExtensions documentation is exactly what i'm trying to use.
Is this a bug/issue or am i missing something?

[lucid valley]

Does your ide show two version in the autocomplete?

[short timber]

No.

[lucid valley]

do you actually have the Collections package installed? As NativeArray is part of the unity core module but the extention class is in the collection package

[hard sparrow]

This ends up resulting in weird, unexpected movement. Am just trying to get it to go from startposition to endposition like a lerp (and add curves after)

It's not even heading to the right spot despite endingtransform being correct

or is this not how you do AnimationCurves?

[swift falcon]

How to make something run asynchronously

[compact socket]

coroutines are effectively asyncronous, otherwise look into asyinc functions

[short timber]

oh, that's neat!
When you said, i went to check it out and it wasn't installed. Since i have access to Unity.Collections in the Editor, my thought was "It is all in the core without any package needed".
It worked! Thank you so much! And sorry for not realizing it. i'll give more thought on next issues 😉

[lucid valley]

don't worry easy mistake. It is weird that the extension class isn't in the same module

[short timber]

true.

[leaden ice]

It seems to me you just need to pass the original prefab reference through two places, it shouldn't be too intrusive:

• the original spawner, which already has the prefab reference
• the spawned "animal", to which you just need to add a single field, or rather repurpose the one you already have

[steep scarab]

yo whats up I'm actually trying to do the exact same thing rn lol

I've been thinking about making multiple falloff maps for different island borders but I'm not sure how to even go about that 💀

[weary heron]

no clue if it would work but https://pastebin.com/Wn4uBzNa

idk how to do corners as of yet

[steep scarab]

yeah thats what I'm thinking

[steep scarab]

I think that re purposing the original falloffmap code to create it might not really work especially well

[wispy badger]

just a quick question about moving objects in NGO.
right now, i want my character to carry an item if you click on it .

/*checks if the object has the "carryable" tag, if an Object is already equipped and if the object is within the players proximity*/
if(c.transform.gameObject.tag == "carryable" && !CarriedObject && Vector3.Distance(c.transform.position, Hand.position) < 4)
                {
                //saves the objects original pos. and rot. 
                orgP = c.transform.position;
                orgR = c.transform.rotation;
                
                //actually equipps the object
                CarriedObject = c.transform;
                coName = c.transform.gameObject.GetComponent<item>().name;
                CarriedObject.GetComponent<MeshCollider>().enabled = false;
                }
if(CarriedObject)
            {
            //makes the object move with the Hand
            CarriedObject.position = Hand.position;
            CarriedObject.rotation = Hand.rotation;
            }

it should work in theory and it actually does, until you run the script in multiplayer. What should i do to make this work in multiplayer? or should I just use a completely different concept, like making the carried object the Hands child or attaching a movement script to the Object itself?

[steep scarab]

keep in mind I haven't started at all I literally just imported the scripts and I'm getting texture errors

but

I think it could be possible to get rounded corners with a bit of geometry

but I think its going to need a couple of things

like calculating the distance from whichever corner we are supposed to be "rounding"

so like

[leaden ice]

what happens in multiplayer that's different? Maybe you're forgetting to make the carried objects positions replicated across the network?

[wispy badger]

for the host, everything works as intended, even on the clients screen. if the cliet tries to pick up an object, it recognizes the object being clicked (checked via debug log), but the object simply stays where it is.

[leaden ice]

sounds like the host has authority over the object

so the host will need to be the one to attach it, or the object needs to be given to the client's authority at that time

[wispy badger]

does this work with server rpc? (i tried, but it cant serialize transform)

[wide star]

Would someone help me understand how I would have to make a script on playerprefs to save toggle please?

[leaden ice]

define "this"

and why would you serialize Transform

you'd send the NetworkObject / id

[wispy badger]

then i try this one first

[west sparrow]

Pretty sure there are lengthy public tutorials on that already

[wide star]

I searched but there was nothing about it just it was from something else a little example from the save sound but from that I can't make a script because it is similar but I don't understand how I would do it

[wispy badger]

i think, i found the problem. when the object is clicked, the "CarriedObject" is only set on the client. the Host gets a NullReferenceException and if i inspect the clientplayer in the Hosts window, "CarriedObject" is still null.

[limber stag]

Hi if i add script to object type mi Cant add script how can i fix it?

[lucid valley]

not sure what you are trying to say

are you trying to ask why you can't add a script to a gameobject?

[limber stag]

yes

[somber nacelle]

does the script name and file name match and do you have any errors in the console?

https://help.vertx.xyz/programming/scripts/loading/script-name

[limber stag]

i fix errors and type back

i fix it and work

thanks

and sorry for mi english

[dense vessel]

Hello,
Is there a way to autofit a text but to tell it to avoid other objects?
Here for example, I would like the text to automatically take as much space as possible in the white rectangle but to not go over the archer image. Is this possible?

Basically something like that. But automatically since the text can change

[lucid valley]

maybe this?

https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/manual/RichTextSprite.html

have the sprite actually part of the text and resize it?

[dense vessel]

Hmm yes but then the image must be the size of the text, right?
Like if I have a small text, the image will be small and if I have a big text, it will be big

In this case, it would be really small...

[lucid valley]

well you can use the size tags to increase the sprite i think

[dense vessel]

Oh. I didn't know about that. But what if it has to take several lines?

The line bellow will still go over it, right?

[lucid valley]

humm i'm not too sure

https://forum.unity.com/threads/is-it-possible-to-wrap-text-around-an-image.1014496/ (Overflow Linked mode, not something i've tried)

[dense vessel]

Oh well I was wrong, it looks not too bad

I mean it's way too big but I just have to adjust it

[dense vessel]

Oh I'll look at that too, it might be even better!
Thanks!

[lucid valley]

https://stackoverflow.com/a/59938447 (another link about it) I can't find anything more up to date

might be the best way for you

[dense vessel]

You're better than me at searching on Google 😂
Thanks a lot!

[potent sleet]

googling is a dying skill

😦

[jolly niche]

Hey, my scriptable objects always keep their changed values after i exit play mode. Is there some easy way to reset them?

[regal marsh]

i have a spawner gameobject that spawns things inside a sphere. the player controls a car, and i want to make sure that when i choose a random point inside of the spawner, the car doesn't occupy it. how do i do that? i'd check if the point is inside a collider but it will always be since the bounds of the spawner are represented by a sphere collider

[potent sleet]

why would you though.

[jolly niche]

i'm using them for an inventory system

[potent sleet]

they're meant for immutable data

[jolly niche]

but they're soo cool

[regal marsh]

i would not use scriptable objects for an inventory

[frank kayak]

I had the same problem a while ago. I made it so I instantiate a new scriptable object of the same type and copy the values into it. I gave it a Init() function that works like a construnctor

[wispy badger]

if (Input.GetMouseButtonDown(0))
        {
        Ray ray = Camera.GetComponent<Camera>().ScreenPointToRay(Input.mousePosition);
        RaycastHit c;
        if (Physics.Raycast(ray, out c))
            {
            if(c.transform.gameObject.tag == "carryable" && !CarriedObject && Vector3.Distance(c.transform.position, Hand.position) < 4)
                {
                        orgP = c.transform.position;
                        orgR = c.transform.rotation;
                        CarriedObject = c.transform;
                        coName = c.transform.gameObject.GetComponent<item>().name;
                        CarriedObject.GetComponent<MeshCollider>().enabled = false;
                }  
        }
if(CarriedObject)

            {
                moveObjectServerRpc();
            }
[ServerRpc(RequireOwnership=false)]
    private void moveObjectServerRpc()
    {
        CarriedObject.position = Hand.position;
        CarriedObject.rotation = Hand.rotation;
    }

still doing something wrong here. it works on the Host and on the client, the Variables are set as soon as I click the object. but on the host, the variables of that client are still null and i just receive a nullreferenceexception while trying to move the object

[frank kayak]

So the original one stays clean, it's probably a workaround tho

[jolly niche]

So should i just store my inventory list as a regular scene instantiate variable?

[jolly niche]

whats init()

[lucid valley]

maybe do a OverlapSphere/OverlapBox at the spawn position and then check to make sure it's clear? (excluding the spawner collider if it has one)

[polar marten]

you're at the start of a very long journey

you might want to use an asset that supports multiplayer already

[frank kayak]

It's just a name, what I mean it's to create inside your scriptable object a new function that receives an object of the same type as a parameter and then set all the values from that object. Then when you need that object, spawn a new one of that type and call that function to set everything up. So you have a fresh object with the same values but the original one stays as it is.

[wispy badger]

any suggestions?

[polar marten]

what kind of game is it

[wispy badger]

competitive cooking. you play in a kitchen with 4 players and need to cook your dish as fast as you can while the other players will try the same thing and sabotage each other

the code is for picking up (e.g.) knifes and carrying them around

[polar marten]

do you have a screenshot

[polar marten]

lol

okay well i would strongly recommend making it local multiplayer, and then focusing on other stuff

[wispy badger]

thats what it was supposed to be. i wanted to start working on multiplayer games with a simple LAN-game

[polar marten]

hmm

[wispy badger]

please dont tell me, netcode is not meant for this typ of game? :-|

[polar marten]

i mean same machine local multiplayer

no

i didn't say that

it's just that unity is bad at realtime networked multiplayer, period full stop

it's sort of a huge waste of time

make it local, not networked multiplayer

and focus on the game

[lucid valley]

going to guess you need to tell the server that CarriedObject has changed? I havent used NCG, but i think you'd have to RPC the change with that networked object?

[potent sleet]

LAN isn't "simple"

[wispy badger]

it's for a school project, so it has to do something with networks. the only criteria we were given, is to make it at least P2P

[polar marten]

change your game design to not require realtime multiplayer.

[potent sleet]

or make a simple p2p communication app

like a chat thing

[polar marten]

anyway, i am trying to be helpful

there are assets.

[frank kayak]

Draggable Object conflict with Tilemap Collider

[wispy badger]

compared to singleplayer games: yes. compared to playing it via wifi and doing this whole "join the lobby from anywhere in the world by just clicking one button": no.

[wispy badger]

well, thanks for you efforts

guess i gotta have to do some explaining to my teacher and the group 😬

[jolly niche]

from a Unity tutorial about lists, what are those values?

[polar marten]

you can still make a game

just think about how to make it simpler

way simpler

in fact i can think of a great game design for a cooking game

have you ever played spaceteam?

[wispy badger]

i´d appreciate it :)

[lucid valley]

its for the BadGuy constructor

[somber nacelle]

those values are irrelevant to the List, they are part of the constructor for the BadGuy type

[lucid valley]

presumably it has a string and an int that needs setting

[potent sleet]

probably the constructor on BadGuy

[jolly niche]

ah my bad

[polar marten]

okay here's a simple way to make your exisitng game networked

make a local (or single) player cooking game. you place orders for the kitchen on a website

that's it

[wispy badger]

thanks. this actually sound more practicable

[polar marten]

yeah let people just write freeform

it'll be funny

[potent sleet]

lemme get an Ass Burger

[polar marten]

lol yeah exactly

[kindred plume]

lol, i will buy this game.

[polar marten]

if you want a real game you make each player (which can be many, single copies of the game that all poll the same url for the current order) submit their own thing

and the person who orders picks which creation is best

kind of like cards against humanity

[wispy badger]

well, the main aspect was sabotaging each other by stealing ingredients or turning off ovens. kinda like mario kart. the main goal is to finish the race but everyone can influence what is happening by throwing shells or something

[polar marten]

you can still do that in local multiplayer. input system has good support for it

how much time do you have?

[potent sleet]

is this a code question?

[wispy badger]

about a month. but i did the entire assets, the character and the scripts within 2 weeks. also i am highly motivated to finish the game

[polar marten]

okay

[kindred plume]

no, sorry i wrote in the wrong channel.

[polar marten]

i think this is a lot of time if you're putting in lots of hours every day so that's all fine

have you ever authored a website with an api

[frank kayak]

sorry to ask, how does it works for threads? Do i need to share it in the chat to keep it up or anyone goes to see them sometime?

[wispy badger]

no

[potent sleet]

dang what kinda school want you to do p2p and u cant even crud

[hexed pecan]

Its visible here in the chat, I suggest you make the thread and bump it if no one responds

[frank kayak]

bump it as in...? 😆

[polar marten]

hmm okay lemme think about this

to make it simple

it's tricky

[wispy badger]

basically, the only thing i have to worry about is to make it use some sort of network. so i could also just make an offline game and add something like an online highscore board

[simple sable]

hey guys, I've got a little problem here, thought maybe someone could help
so I have this piece of code that changes the transparency of a specific tile from my tileset to semi-transparent
I want to change the code a bit and use DoTween's DoFade but I'm not sure how to do it. I tried using GetTile but that didn't work.

If anyone could help, I would greatly appreciate it!

[outer nimbus]

How can i delete a instantiated object?
I tried this but it didn't work.

If i do that i get the error: The name 'Bullet' does not exist in the current context.

[simple sable]

I think it's because you've declared the Bullet in the if statement and therefore it's not accessible in the coroutine.

[outer nimbus]

Yeah i thought that could be the problem but idk how i can wait in a if statement.

[simple sable]

Maybe try declaring it before, and just assign to it what you want in the if statement.

[outer nimbus]

ohhh

ill try

Uhh now i get this..

[inner yarrow]

I have tried stuff with portals several times, and in every video I have watched, the camera will make the portal it's behind invisible before taking a picture, and then make it visible again afterwards. I have tried this:

myWormhole.Renderer.enabled = false;
//positioning stuff
cam.Render();
myWormhole.Renderer.enabled = true;

However, it still ends up taking a picture of the portal. Also this is being called in Update, not sure if that's causing problems. Please ping me if you have any ideas?

[simple sable]

Just say var Bullet; and then in the if statement Bullet = Instantiate(bullet).

See if that works.

[leaden ice]

You don't need that coroutine whatsoever

[simple sable]

But I'm not sure what you're trying to achieve so I might be wrong.

[leaden ice]

Just call Destroy(Bullet, deleteTime); right after creating it

No need for the coroutine

[outer nimbus]

Then i wont get a bullet.

[leaden ice]

Yes you will

Why wouldn't you get a bullet?

[simple sable]

Just a tip here, you might want to try and set the variables you don't need to be public to private. Maybe even add a "_" before their names. Just to keep things clean. You can use [SerializeField] to make them visible in the inspector.

[leaden ice]

When you call Destroy the way I said to, it will wait that much time before destroying it

You will have your bullet

[outer nimbus]

My bullet is getting deleted right after it spawns now.

[ebon timber]

got a timer?

[outer nimbus]

yus

he said i dont need

it

[ebon timber]

using delta time?

[outer nimbus]

no

[ebon timber]

what's the deleteTime you're sending it?

is it seconds or float

[outer nimbus]

Uh i use yield return new WaitForSeconds

How can i delete my bullet

The bullet stuff is at the bottom.

[ebon timber]

is WaitForSeconds built into unity?

[outer nimbus]

Idk

[ebon timber]

i usually just do something real quick and be done with it

[outer nimbus]

Can you help me!

Please

[cedar pivot]

hi how can i make a formation system for a soccer game

[ebon timber]

hrm bullet

is the collision for bullet handled in hitscan?

[cedar pivot]

if the value is "4-4-2"

players needs to spawns at the formation position

[ebon timber]

you need to create an object that handles player positions

store the intended formation position offsets there

[prime sinew]

what did you set deleteTime as

[outer nimbus]

5

Ik why it doesn't work but i dont know how i can make it work.

[prime sinew]

Praetor already gave you the answer

you dont need DestroyImmediate..

just use Destroy

[outer nimbus]

yeah ik.

But it still doesn't work

this looks not possible

Bullet does not exist in deleteTimer

you have errors, or you're coding in discord

[ebon timber]

check your console for the errors

usually those answer more questions than a stranger can

tbh i'm a novice at this engine but an expert in game dev and coding

always check between your chair and your computer

[prime sinew]

what's your engine of choice?

[ebon timber]

whatever i'm paid to code

i just came off a typescript engine and now my employer has me on roblox, which isn't very fun

[outer nimbus]

Ik the problem, It is because it's because I've declared the Bullet in the if statement and therefore it's not accessible in the coroutine.

[ebon timber]

at least lua has globals

that last engine had no globals

[prime sinew]

which is what I pointed out

so your code didn't even compile?

I'm a very experienced user with Unity and C#, and I'm trying to make a fast paced multiplayer game. I've tried doing it before but every time I tackled a multiplayer project, it ends up becoming extremely non-scalable down the road and I give up because of the immense amount of refactoring that I'd have to do.
So my question is, are there any recommended papers, articles, or documentation that I could reference that cover the design strategies for a scalable multiplayer game?

[next steeple]

So for people who use composition over inheritance, I've been wanting to try switching to composition but this one scenario keeps tripping me up. In my game I have a weapon class that all weapons inherit from. The player can equip any of the weapons since they inherit from the weapon class. The player can fire the weapon because the parent abstract weapon class has a fire method on it and each weapon implements their own fire method. Is that actually possible with composition?

[inner yarrow]

Please help.

Hi. Is there a way to create SO with a default value based on another SO? Basically I want to create Item SO that will look at list of items in another SO and get the count of that list.
EDIT: I mean create in Editor not in game.

[next seal]

what does that mean exactly I kind of dont understand the second part

what does it mean that I hold on to the objects through the domain reload >_> and htat it prevents the GC from collecting them

which list should I clear before domain reload callbacks and recreate after, and how do I even do that like i know how to clear lists in theory but I dont know how to do that before or after any domain reload callback

[main shuttle]

You are aware of Unity Gaming Services: https://unity.com/solutions/build-backend#multiplayer / https://unity.com/solutions/gaming-services
It has hosting, matchmaker, lobby system and more that all can scale the way you would want if you use Unity Netcode, and is free up to a point afaik.
For the networking questions, I would suggest asking in #archived-networking, if there are any networking experts they would hang out there.

[ocean swallow]

any idea why the bullets dont move?

[main shuttle]

Bullets are probably kinematic on the rigidbody.

[ocean swallow]

ayyyyyyyy

[main shuttle]

Well that wont work then.

[ocean swallow]

yeah it shoots now

[main shuttle]

Just remember, isKinematic kills all simulation of your rigidbody. You need to use the specific methods for isKinematic to move it.

[ocean swallow]

what do the kinematic methods allow you to do that makes the distinction relevant?

[main shuttle]

https://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html

Controls whether physics affects the rigidbody.
isKinematic kills the physics of the rigidbody. With the kinematic methods, you can move the rigidbody and still have the physics checks in place that you would not get when you would reposition it with .position. So you can never teleport through a wall with the kinematic methods, which would be possible with the .position style.

[shell scarab]

Hello, how would I either have Quaternion.Slerp NOT affect the Z axis, or Vector3.Slerp take the shortest rout?

I am by no means familiar with Quaternions, although I am understanding them a bit better each time I work with them, as well as having watched some basic videos explaining them.
I know that Quaternion.Slerp will take the shortest rout, but I want to do that without affecting the Z rotation if both z rotations are the same from rotation a to rotation b, like how Vector3.Slerp does, but if I use Vector3.Slerp it does not take the shortest rout because, as far as I am aware, it reads 0, 0, 0 as well 0, 0, 0. I've tried Slerping from the negative of the rotation based on the signed angle between rotation a and b, but that only works some of the time. Any help or advice?

Also I cannot just set the z rotation to 0 after the quaternion slerp because if there's a change of rotation on the z axis it needs to do that, just not if there's no change.

[unreal notch]

Hey, im working on writing myself an enemyAI and animation controller, because I hate using the animator mecanim for 2D sprites.

In the mecanim, you can transition between states with exit time
set that to 1, and the animation automatically goes to the next state when the current animation is finished.

How can I achieve this through code? I DO NOT want to be setting custom delay timers for every unique animation, I just want some way in code to confirm that the current animation has finished

[rain minnow]

On your animation state class you can have a similar field to represent exit time. Give it a default value of 1, so you can input a custom time when needed for unique animations . . .

[unreal notch]

ok see thats the thing I want to avoid doing. I do not want to come up with custom times to input there for every unique animation I have

[woven ocean]

Hey I was wondering what counts as code-beginner, general and advanced. Im fairly familiar with C#/Java as a backend dev, but not super familiar with good Unity practices and all of its features. Where would my questions belong?

[unreal notch]

but I think I found the answer

if(anim.GetCurrentAnimatorStateInfo(0).normalizedTime > 1)

this might do what I'm looking for

[rain minnow]

I'd start with #💻┃code-beginner if you're new or learning unity. People will tell you if your question is better suited for a higher level channel . . .

[woven ocean]

Thanks

[rain minnow]

Based on beginner or intermediate c#, you can kind of tell where your question may belong. Mostly architecture and systems design talk, or performance ends up here

Beginner is mostly syntax, formatting, collision, and a bunch of mechanics (not entire systems)

Advanced is anything beyond, like working with packages, some low-level stuff, ecs, graphics/core systems. Crazy stuff. You'd know if your question was advanced though . . .

[dusky spear]

if i call this function multiple times once for each shape in the shape group, but with the same list every time, will it add all of them together or just overwrite it each time

https://docs.unity3d.com/ScriptReference/PhysicsShapeGroup2D.GetShapeVertices.html

[woven ocean]

Im mostly interested in unity specific design patterns, so I’ll stick to beginner for now. That’s for the details.

[somber nacelle]

it should overwrite, that's kind of the whole purpose of it accepting a list as a parameter

[dusky spear]

ok

hmm i could use this function instead

https://docs.unity3d.com/ScriptReference/PhysicsShapeGroup2D.GetShapeData.html

if i pass null or none or whatever as the first list since i dont care about the shapes i just want the vertices would it complain?

[somber nacelle]

just confirmed this calls Clear on the list https://github.com/Unity-Technologies/UnityCsReference/blob/master/Modules/Physics2D/ScriptBindings/Physics2D.bindings.cs#L2455

[somber nacelle]

you'll likely get a NRE since it calls AddRange on both lists without checking for null first

[dusky spear]

ok

il just make a list and then not use it

[karmic bloom]

I know you can click to move using the NavMesh agent on your player in 3D, does anyone know of a video/tutorial/website that does this but also uses grid based movement? Or if anyone has any suggestions. Thanks

[potent sleet]

grid based movement is just snapping to Vector3Int

[karmic bloom]

Right I can do grid based using WASD, but point and click I can't seem to get. I can get the player moving to the point I click, but they go in the straightest path

[potent sleet]

you want the navpoints or destination to be on grid

navpoints will def be harder

you'd have to mess with the navmesh algorithm

I think it's still Astar

[dusky spear]

wait if im getting the shapes from a collider2d, when i initialize the physicsshapegroup2d first, what do i put in the parameters if i dont know how many vertices the collider has

[karmic bloom]

Gotcha. I have WASD working fine, the only issue is I then am having a tough time wrapping my head around how to tell the script if the player can or can't walk to the next tile on the grid.. I was using a raycast, but then I would have to check all 4 directions and I think it's just too much. I felt like clicking would be the easiest way?

Because then I can just check the clicked location (I think).. I've only ever done regular player controllers (WASD, space to jump) so this is my first attempt at this

[potent sleet]

do you mean with navmesh ?

which grid

[karmic bloom]

Navmesh seems to be what most suggest online, but it doesn't have to be navmesh

[potent sleet]

you can check if the path is reachable

[karmic bloom]

grid meaning the grid I've created in unity

Using 3d objects.

They're just spaced apart specifically to where right now when the player presses "W" for instance it moves one tile

[potent sleet]

so why not use tilemap instead

do the aStar pathing on the tiles

[karmic bloom]

I guess I don't know anything about it?

Also wasn't aware you could tilemap in 3D

I thought that was a 2D feature.

[potent sleet]

it is kinda

im using it here

[karmic bloom]

hmm do you know of any videos that explain it well?

Are you using click to move or just the grid for something else

[potent sleet]

my click to move cheats tho

it's navmesh

but Im sure you can use the same method on the tiles itself with Astar pathing

[steady moat]

You should start by using Unity Navmesh.

If you have performance issue, you can then try to implements your own pathfinding solution

[karmic bloom]

I have used it and it works.

Just not the way I want.

I am asking if I can get the player to move on a grid vs taking the straightest path.

[steady moat]

So you want your player to move 1 tile ?

[karmic bloom]

1 would work for now.

[potent sleet]

you can set to limits yourself

you just cant directly modify the navmesh generated points as far as im aware

[steady moat]

Do you limit your movement ?

[karmic bloom]

No I have no limits set. So inside NavMesh I can tell it to only allow the player to move 1 tile?

[steady moat]

I dont think.

[potent sleet]

you can calculate how much distance it would be from player to mouse clicked pos

[karmic bloom]

gotcha

[potent sleet]

if its greater than 1 tile size, dont move

I've been trying to make a bullet, but i've been having trouble, and i can't figure it out. Could one you guys help me?

public override void Shoot(Vector2 _shotDirection, Vector2 _shotMomentem, int playerId)
    {
        Bullet bullet = Instantiate(GameManager.instance.bulletPrefab).GetComponent<Bullet>();
        GameManager.bullets.Add(bullet);
        Vector2 direction = _shotDirection + _shotMomentem;
        // Rotate Gun
        float rotZ = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        bullet.transform.rotation = Quaternion.Euler(0f, 0f, rotZ);
        if (rotZ < 89 && rotZ > -89)
        {
            bullet.spriteRenderer.flipY = false;
        }
        else
        {
            bullet.spriteRenderer.flipY = true;
        }
        bullet.transform.position = GameManager.players[playerId].transform.position;
        Debug.Log(GameManager.players[playerId].transform.position);
        bullet.transform.position = bullet.transform.right * GameManager.instance.bulletSpawnTeleportDistance;
        bullet.transform.position = new Vector3(bullet.transform.position.x, bullet.transform.position.y, -1f);
        bullet.Init(speed, damage, _shotDirection, _shotMomentem, bulletSprite);
    }```

Elaborate

[main shuttle]

What is the problem? You say you have trouble and can't figure it out, but don't specify anything about it.

[clever lagoon]

whats not working as expected

[brittle sparrow]

I'm not sure if this is the right channel for it, but I was wondering if, instead of using Collider Components for collision, the mouse can check if it's within a sprite's rect boundaries, and if the pixel of the sprite it is currently touching is transparent or not (and just in case, using an alpha threshold of at least 0.05 or something). The pixels of the sprite would be of the camera's resolution, not of the Texture2D's.

If it's not a thing, I could implement it but I'm not sure how I can get the reference of the Camera-resolution-processed Texture2D objects
Or I could just give up and use the normal Texture2D? But it won't always work out
