this wont work

and i cant figure out

how else to do it

[rare basin]

jezus

i just told you

10 times

[hexed terrace]

then you have somewhere else changing the Y val

[frank flare]

for my object it's right and left

[rare basin]

and you are still passing vector3 for a x parameter

[nocturne phoenix]

no

that was showing

that wont work

*that was for showing

so what else can i use

[rare basin]

dude

[nocturne phoenix]

i removed that already

[rare basin]

did you read my messages

[nocturne phoenix]

i know why its not working

[nocturne phoenix]

yes

[rare basin]

i already explained you how to do it

#💻┃code-beginner message

[nocturne phoenix]

OH

i just

understood what that does

😭

my brain is a little slow

so essentially manipulate velocityvector instead of rb.velocity

and then declare rb.velocity the same as velocityvector

right?

[frank flare]

that's the problem

[rare basin]

  if (Input.GetButton("Horizontal"))
  {
         Vector3 velocityVector = horizontalInput * speed * transform.right;
         velocityVector.y = y;
         velocityVector.z = z;
         
         rb.velocity = velocityVector
   }

[frank flare]

Ignore cow rotating when moving forward

[nocturne phoenix]

no

i understood that

ty

[frank flare]

it's because something else is wrong

[nocturne phoenix]

wait why are we doing velocityvector = .... instead of velocityvector.x = ...

thats a question i got

[rare basin]

jezus xd

[nocturne phoenix]

OH

[rare basin]

you cannot set x to a vector3

[frank flare]

I'm not even sure where does it move, but it moves to some specific direction and that's what I don't want

im trying to make a laser pointer but it seems like it has a delay when looking around with the mouse. Any smart fix for it?

if (Physics.Raycast(laserStartPoint.transform.position, laserStartPoint.transform.forward, out laserHit, 100f, ~ignoreLayer))
{
    if (laserHit.collider != null)
    {
        lineRederer.SetPosition(0, laserStartPoint.position);
        lineRederer.SetPosition(1, laserHit.point);

    }

[nocturne phoenix]

my bad i had that from a while ago and forgot to remove it 😅

dw i aint transphobic

[fickle plume]

Most likely delay is related to movement and the timing when this is called.

Put debug messages where this is called and see if they are delayed

[tawdry rock]

It's in the update function so it should be pretty accurate, no?

[fickle plume]

then keep dropping debug messages up the chain to find the source

This involves physics as well so will be executed on physics frame (not sure exactly when raycasting is called in this case)

You can have more Update cycles before it executes

[restive ore]

can anyone teach me how to make a better map for my 2d rpg game?

[rare basin]

this is a code related channel mate

[restive ore]

oh wait

oh sorry

[keen dew]

There's nothing in this that involves mouse movement so potentially the code that rotates (?) the laser pointer is what causes the lag

[rare basin]

or the if just doesnt execute

everytime you would expect

put debug logs in there

[tawdry rock]

it's only not execute if i looking up the sky and the raycast cant find a collider

[rare basin]

nothing in this code could cause delay

[tawdry rock]

Well then idk what causing this. (the delay, not when i look up to skyebox and it lose the connection)

[fickle plume]

Yea, it looks like raycast would give you an immediate result in Update or FixedUpdate, but if you expect to see changes affect something physics related, those will be only after next Physics frame.

[hexed terrace]

It breaks when you look up because there's no hitpoint in the empty sky

The visual for this also doesn't even need to be updated.. just have it as a child of the gun, positioned correctly, and toggle it on/off

[tawdry rock]

Yea, i know that but it's not about the break, when i walk right or move mouse the line cant follow the gun smoothly

[restive ore]

uhh anyone can help me idk how to script

when i click edit script

[tawdry rock]

the start point is a child of the laser attachment which is a child of the weapon.

[restive ore]

it says blender word point and those randoms

what do i press?

[tawdry rock]

but yea i might end up using some photoshoped image instead of this stupid linerenderer

or do i have to download visual studio?

oh

so i gotta install visual

[hexed terrace]

You've got to install something to code with

[restive ore]

ok

[tawdry rock]

Notepad

[fickle plume]

@restive ore You should start with a Unity course explaining basics https://learn.unity.com/pathway/unity-essentials

[celest spoke]

Is there anyone here that is good at 2D games, im currently trying to make a scenechanger but my player is not colliding with the scenechanger object that i have created, and i cant for the love of my life find what the problem is.a Any help is greatly apperitiated! ❤️

[restive ore]

im actually watching a unity tutorial rn

but then suddenly he just randomly start scripting

[fickle plume]

So follow a proper course I've linked, not random tutorials

[tawdry rock]

make it trigger and use OnTriggerEnter2D

[restive ore]

ok

but now im in visual studio

i pressed unity

game development with unity

do i have to press C++?

[fickle plume]

@restive ore course explains everything, including VS install

[restive ore]

ohh

ok

[celest spoke]

Yeah i have that and i have made sure that they are on same layer etc, and i even put in a Debug log and nothing is showing 😦

[modest dust]

Do you have a Rigidbody2D on any of the two colliding objects?

[celest spoke]

I have it on my player yes

[hexed terrace]

https://unity.huh.how/physics-messages

[celest spoke]

That didnt really help but ty anyways, i have been looking at that page all day yesterday. Something is just wrong and i cant find it 😦

[languid spire]

start with screenshots of the inspectors of your 2 objects and post your !code

I posted the bot for a reason

[celest spoke]

i dont understand how it works sorry im new here

[hexed terrace]

You're using OnCollisionEnter2D and both colliders are set to Triggers

[hexed terrace]

So you failed at following this, which explicitly takes you through this setup 😄

[somber sun]

Does anyone know how to fix this, it gets an error everytime i press space😭.

[languid spire]

rb is null because you never assign it to anything

[hexed terrace]

Yeah, assign your rb
And don't post photos

[celest spoke]

well i did that and i tried having both on, having 1 on and other off etc. but still not working so

[somber sun]

Ah sorry, thanks

[tawdry rock]

The player boxcollider doesn't need to be a trigger if the scene changer's is ticked. also should work:

public void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.CompareTag("Player"))
        {
            Debug.Log("Player is colliding");
            SceneManager.LoadScene(sceneToLoad);
        }
    }

[hexed terrace]

remove the rigidbody from the scenechanger too.. you only need 1

[languid spire]

and this tells you what if
A) Nothing is colliding
B) It Collides with something other than Player
?

[thorny wedge]

Yo. i got 5 extensions installed at vscode : unity ,C# , .NET, C#dev kit and intellicode. They take 2.7gb ram, which is concerning. is this normal?

[hexed terrace]

If you downloaded them from within VSC, yes ..

[celest spoke]

ok so now i changed the code, i removed the rigidbody from screenchanger and i only have the trigger on the LevelChange object. And still nothing is working, im losing my minddd

[hexed terrace]

Put a log before the if statement to make sure the collision is happening

public void OnTriggerEnter2D(Collider2D collision)
{
  Debug.Log($"collided with {collision.name}");
        if(collision.CompareTag("Player"))
        {
            Debug.Log("Player is colliding");
            SceneManager.LoadScene(sceneToLoad);
        }
    }```

[celest spoke]

Nope they are not colliding because im not getting a message :/

[remote sequoia]

When player collide with tagged "Enemy", enemy acts like player has powerup. İ dont want this but i couldnt find where is the problem?

[hexed terrace]

Do a screen recording of what's happening, let's see if that shows anything

[hexed terrace]

hasPowerup is true.. find out why

[remote sequoia]

what?

[thorn holly]

The variable hasPowerup is set to true

[hexed terrace]

Oh, actually.. your condition is

if ((enemy) OR (enemy fast AND hasPowerup))

so any normal enemy will trigger the first one

[thorn holly]

Ah

Yep that’s it

[hexed terrace]

You'll want to put brackets round the enemies

if ((enemy OR enemyFast) && hasPowerup)

[remote sequoia]

lets try

yeey its worked!

but how

[hexed terrace]

or not

[hexed terrace]

because of the logic, look at the difference between the two statements

[remote sequoia]

i saw

[celest spoke]

Sorry i had to listen through it since it had audio lol

[remote sequoia]

thankss

[thorny wedge]

ah alright, do you know if there is a way to reduce it or not

[arctic ibex]

hello! I'm having an issue with my code (atleast i think it's code related)
In the inspector, it keeps tellign me "Object reference not set to an instance of an object" but i cant find any references that dont have objects set? And it doesn't cite any code, just some long list of things related to an animator. THe animator currently isn't working, the clips, start and end states aren't showing up, even though i deleted the whole thing and made a new one. I think it is an issue with the object I'm trying to animate, but i can't figure out what it is.

[hexed terrace]

argh, why did you not show the inspector

[hexed terrace]

haven't got a clue

[thorny wedge]

alright thank you

[languid spire]

That's not your code, it's an Editor bug. Restart Unity

[arctic ibex]

Oh epic, thanks!

I have been trying to figure that out for half an hour:)

[thorn holly]

I’d just use regular vs

[celest spoke]

Here you go @hexed terrace

[languid spire]

The UnityEditor bit is a bit of a giveaway

[arctic ibex]

Alright, I'll look out for it in the future

[languid spire]

you should never get UnityEditor errors unless you write your own Editor code

[arctic ibex]

👍

It worked

thx

oh side note, any reason why this isn't jumping?

[hexed terrace]

What are you doing with these two layer fields?

[thorn holly]

Remove the time.deltaTime from the jump equation

[arctic ibex]

oh right

thankyou

[celest spoke]

the top one if for collision objects so i cant go through certain objects and the other one is so i can interact with specific objects when pressing E

[hexed terrace]

It's possible this affects your trigger collision

[celest spoke]

want me to send you the code?

[thorn holly]

Also, due to your code, jumping will remove all horizontal velocity. Is that intentional?

[arctic ibex]

wait it does?

[celest spoke]

@hexed terrace if you wanna look at the code here it is 👍

[thorn holly]

Yeah, but setting the velocity instead of adding to it, you’re resetting the horizontal velocity to zero

[arctic ibex]

no it doesn't

but i keep my velocity when i jump

I just tested it

oh wait maybe not

[thorn holly]

I was wrong yeah

You’re setting transform.position for horizontal velocity so yeah you’re good

Mb

[arctic ibex]

alright! I'll keep that in mind tho, i didn't know you could add velocity instead of setting it

[thorn holly]

Yeah, it’s .addForce or something

Or just += to the velocity

[arctic ibex]

huh, okay I'll have to go look tha tup

[arctic ibex]

out of curiousity, is there any easy way to set where a player spawns depending on which scene you just left? or do i just need to make a logic script any a bunch of variables?

[celest spoke]

I honestly dont understand how to paste code with that tool

[hard hornet]

you could make an object with dontdestroyonload that has a reference to the last scene

a variable reference to the last scene you were in

[celest spoke]

https://paste.ofcode.org/vFFGdjMGUP3WDFS3LswNG5 @hexed terrace

[arctic ibex]

what would i use to make the variable match the last scene? is there something built in for that already?

[hard hornet]

i dont think so, you'd need to take care of that yourself

you could make it a singleton to set it more easily

[arctic ibex]

whats that?

[hard hornet]

so it can be accessed in every script easily

without references and all that stuff

[languid spire]

It's real simple. Open one of the web pages, copy/paste your code into it, save it, then post the URL here

[arctic ibex]

how do I do that? Is it just something I declare at the start of the script?

[hard hornet]

using UnityEngine;
using UnityEngine.SceneManagement;

public class LastSceneManager : MonoBehaviour 
{
  public static LastSceneManager Instance { get; private set; }
  public int lastScene;

  public void Awake() {
    Instance = this;
  }

  public void SetLastScene(int sceneId) {
    lastScene = sceneId;
  }
}

then you can reference it anywhere in your scripts like this:

LastSceneManager.Instance.SetLastScene(0) //for example

let me know if something doesnt work i dont have unity to test if it works lol

you can also just directly do

LastSceneManager.Instance.lastScene = 0;
``` btw

[hexed terrace]

You're not using physics to move, so you won't get collisions

[celest spoke]

So how am i colliding with my NPC:s, enemies and colisionobjects?

[hexed terrace]

Vector3 newPosition = transform.position + new Vector3(direction.x, direction.y, 0) * speed * Time.deltaTime;

        // Check if the new position is walkable
        if (IsWalkable(newPosition))
        {
            // Move the object to the new position
            transform.position = newPosition;```

this is just teleporting the player to it's next position each time

[hard hornet]

i forgot to also add, change it to this so it stays between scenes:

using UnityEngine;
using UnityEngine.SceneManagement;

public class LastSceneManager : MonoBehaviour 
{
  public static LastSceneManager Instance { get; private set; }
  public int lastScene;

  public void Awake() {
    Instance = this;
    DontDestroyOnLoad(this);
  }

  public void SetLastScene(int sceneId) {
    lastScene = sceneId;
  }
}

then add it to a random object in the first scene

[hexed terrace]

your iswalkable method checks

[arctic ibex]

thankyou! Do you mind i fI ask some questions so I can understand what it does better?

[hard hornet]

sure go ahead

[arctic ibex]

What does the "Instance = this" do? is that a reference to something?

[celest spoke]

do you have any god fix for this or am i fked? I have mostly been following youtube tutorials since im new at this so

[hard hornet]

the this keyword references this script basically

this script in this object

[arctic ibex]

Oh alright, so what does the instance do? is it saying any mention of "Instance" is refering to this script?

[hexed terrace]

of course you're not fucked.

[hard hornet]

it works the same as ```cs
GetComponent<LastSceneManager>()

[celest spoke]

do you mind helping mea finding a fix? i really aperitiate all the help you are giving me

[hard hornet]

it sets the static variable Instance (static meaning it can be used in ANY script) to this exact script in this exact object

[arctic ibex]

Okay. So any mention of the variable Instance in ANY script is refering to this script?

[hard hornet]

it doesnt need to be named instance btw, it can be named singleton and whatever you want
but yes any mention of the variable LastSceneManager.Instance is refering to this script

but of course there can be only one object with this script then, since more will just overwrite each other

[arctic ibex]

Alright, that makes sense! Sorry for all the questions, I just find using code I don't understand gets me even more lost

[hexed terrace]

You either need to change to using forces to move, so you're actually using your RB.. or.. you could just use existing code to make your own trigger.

It'll be easier to do your own thing.
I'm not going to hold your hand through it.. look at your Interact() and IsWalkable() methods, look at how they detect things.. use that as the base for your level change. Doing this means you can remove rigidbodies from the player etc

[arctic ibex]

What does the { get; private set; } do?

[hard hornet]

i shouldnt have written like this to be honest lol especially if you dont get it

but basically private set means it can be only set by this script, even though its public

[arctic ibex]

haha, I'm so used to Visual studio code automatically doing the other half o f the brackets i totally forgot to do them

[hard hornet]

you can totally remove it

[arctic ibex]

okay, neat

[rich adder]

You still need a safeguard or when 2 instances exists

[arctic ibex]

so i just add LastSceneManager.Instance.SetLastScene(0) to my trigger before it switchs scenes?

[celest spoke]

Allright, i think i just have to start over in that case cuz i dont know muich about this, let alone changing and using code i have allready written, but i really wanna say thanks for the help ❤️

[hard hornet]

yes, the 0 is the scene index

[slender cargo]

Whats the best way of going back and re-getting a random array element?

[rich adder]

void Awake()
    {
        if (Instance != null)
        {
            Destroy(gameObject);
            return;
        }

        Instance = this;
    }```

[hard hornet]

yes you can do that too for safety

you can add that to the script

[arctic ibex]

what is this for?

[rich adder]

safeguarding

[arctic ibex]

agaisnt what?

[hard hornet]

if there's more than 1 object with this script it'll destroy the rest

and keep only one

[hexed terrace]

You do not have to start over at all.

Look at this code, copy it into a new method and THINK about what you could change/ do to check for another layer 🤔

[rich adder]

if you somehow happen to have a copy in another scene

[arctic ibex]

oh okay

[rich adder]

you dont want to ovewrite it

[slender cargo]

is there a way to write a if statement which also generates the random element?

[rich adder]

make a method that returns the random element?

idk what ur asking tbh

[hard hornet]

you can just copy and paste it of course but that looks ugly

[rich adder]

yes DRY code

[hard hornet]

private GameObject GetRandomModule() {
  return CityModules[Random.Range(0, CityModules.length)];
}

you could add this

if citymodules is in the scope of the class

[slender cargo]

I'm trying to make it so it will re-roll it if it was the same city module as the module before

if that makes sense

[scarlet skiff]

isnt this correct? i still get a NullReferenceException: Object reference not set to an instance of an object Fireball.Update() error

[rich adder]

use a while loop

give it a max iterations too as a guard clause

[rich adder]

love it...posts screenshot of editor 🙄 but clips the line numbers

genius

[swift crag]

do you have line numbers disabled?

[slender cargo]

I'll try it out, thanks

[arctic ibex]

so if I wanted to check what the last scene was, would i still need to reference this script?

[scarlet skiff]

ohhh sorry i didnt know which one it was, line number is 6

[swift crag]

This code has nothing to do with the exception.

[hard hornet]

it would just be LastSceneManager.Instance.lastScene

[swift crag]

The exception is on line 17 of Fireball.cs

[rich adder]

line number is 17 on diff script

[swift crag]

You've shown us FireballSpawner.cs

[arctic ibex]

alright, thanks for allt he help!

[scarlet skiff]

yea i thoguht that might been the case too but got told to post here

[rich adder]

nah bro this is the right channel

you just sent the wrong script

capish?

[swift crag]

Assets/Scripts/Fireball.cs:17

[swift crag]

Fireball.cs, line 17

[rich adder]

there we go

[swift crag]

Turn on line numbers in your editor.

[rich adder]

now why are ur efin lines disabled

[swift crag]

They will make your life significantly easier.

[scarlet skiff]

idk thats how my vs was when i downloaded

[swift crag]

https://learn.microsoft.com/sr-latn-rs/visualstudio/ide/reference/how-to-display-line-numbers-in-the-editor?view=vs-2019

[rich adder]

:doubt emoji

[swift crag]

The default configuration for visual studio has line numbers enabled.

oops, this is...a random language

serbian!

well, the actual article isn't translated

[hard hornet]

also next time you can double click on the error

[hard hornet]

and it'll direct you to the exact line and script

if you didnt know that

[rich adder]

ok there we go

[scarlet skiff]

ye i asked one on my class but bro i didnt change anything

[rich adder]

so playerMovement is null

[scarlet skiff]

but ye i got it on now

[scarlet skiff]

the script worked when i didnt spawn a fireball via a "spawner" why would there be a problem now

[swift crag]

because playerMovement is null...

[rich adder]

did you assign it in the inspector?

[swift crag]

A prefab cannot reference a scene object.

So there is absolutely no way for the fireball to have a reference to playerMovement as-is

[hard hornet]

you'd have to set it through the fireballspawner script

[swift crag]

bingo

[rich adder]

yes you need DI

[swift crag]

I wouldn't even called this "dependency injection"

i mean

i guess it is

[rich adder]

in unity it is

thats the best we got 😢

[swift crag]

but when I hear "DI" I think of 34-layer casseroles of wildly overcomplicated containers and frameworks

[rich adder]

I use this 🙂
https://learn.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-8.0

[swift crag]

the fireball spawner is in the scene, so it can reference a PlayerMovement in the scene

then it can assign the playerMovement field on the fireballs it instantiates

[rich adder]

the unity version 😛
https://unity.huh.how/references/simple-dependency-injection

[swift crag]

Vector2 vec;
vec.x = 3; // dependencies injected!!!

⚠️ extreme DI in progress ⚠️

[hard hornet]

im scared of people who write initialise instead of initialize

[swift crag]

bri*ish

MonoBehaviour moment

[rich adder]

are they or I think aussie, same tomatoes xD

[scarlet skiff]

ok ok so the problem is when i assign this in the inspector, as a perfab it doesnt save it

the Player Movement

[rich adder]

https://unity.huh.how/references/serializing-component-references

[slender cargo]

Will this work? So it will keep calling newModule() until the previousObj isn't equal to next module?

[rich adder]

You cannot add scene references to prefabs

[swift crag]

Prefabs can't reference scene objects. What if you spawned the prefab in a different scene?

[rich adder]

first i'd put an iteration max as guard clause
if somehow previousObj is always NextModuleObj you're stuck

[late bobcat]

Hey guys i made a 2d soccer game and i wanted to test it out with my friends online, do you have some sort of tutorial to do that?

like setting up multiplayer etc

[rich adder]

also what is newModule do

[late bobcat]

i tried tarodev one but i couldn't accomplish much

[hard hornet]

if you made it... it wont be that easy to convert

especially if youre starting out

[rich adder]

the tarodev one is the closest you'll get to your thing

[late bobcat]

ye exactly what i tought

[rich adder]

multiplayer isnt trivial

[rich adder]

why not just return and obj

[slender cargo]

How would I put a iteration max?

[rich adder]

instead of void

[late bobcat]

i saw that x)

[slender cargo]

How would these work?

[late bobcat]

so any idea on how to do that? like should i make it from 0 while adding multiplayer at the same time or

[rich adder]

  int maxIterations = 50000;
    int i;
    void Method()
    {
        while(something && i < maxIterations)
        {
            //do work
            i++;
        }
    }```

[slender cargo]

oh right

that makes sense

[thorn holly]

Is this something you want to happen over multiple frames?

[hard hornet]

you'd need to understand basic concepts of multiplayer if you dont know them yet

[rich adder]

just return the CityModules[Random.Etccc.
change void to whatever type that returns

[late bobcat]

ye i know close to 0 about multiplayer, started with unity 3 days ago

[hard hornet]

soo i'd start with a new simple multiplayer game made from a tutorial

[late bobcat]

just had some knowledge in c

[hard hornet]

i recommend mirror or fishnet, i dont recommend photon

[rare basin]

dont make a multiplayer game

when you are just starting with unity

why would you shoot yourself in a foot

[late bobcat]

ahahah

[rich adder]

3 days in unity you should not be doing multiplayer at all

[late bobcat]

i didn't think it was that hard

[rich adder]

no one does

[late bobcat]

my bad then 😛

[slender cargo]

I don't understand

[rich adder]

they think its like roblox or something

[late bobcat]

never played roblox but i get what you mean

[rich adder]

do you not know how to return another value besides void in a method ?

[gaunt ice]

some knowledge.... have you used socket?

[rich adder]

  public class SomeType { }
    SomeType somethingCool;
    SomeType Method()
    {
        return somethingCool;
    }```

[slender cargo]

ohh I think I've played around with this a little

[rich adder]

basically this
#💻┃code-beginner message

[late bobcat]

guys is alteruna a scuffed multiplayer version?

[slender cargo]

righttt ok, that makes sense

[rich adder]

you should learn more about what you're doing before shopping for multiplayer frameworks

[late bobcat]

i'm just asking

[rich adder]

frameworks are made different for diff use cases / needs

you have to know your own cases which you gain by experience. Not by jumping head first in a shark tank

[arctic ibex]

@hard hornet It's working perfectly! That you so much!

[slender cargo]

so whats the point of doing this over the way I had it?

[late bobcat]

Never said i wanted to buy alteruna (didnt' even know you could tbf). I just saw that tutorial yesterday and it felt like a short, not so-good way, of transforming your game into a multiplayer

[rich adder]

its more implicit on what it does

[celest spoke]

Hey just a general question, when im coding in Microsoft visual studio i dont get any colors for classes, functions etc. But all of the people that are on youtube does. is there some kind of package that i have to download? It makes it really confusing when everything is the same color.

[slender cargo]

Would you do something like so?

[rich adder]

yes

[rich adder]

int maxIterations = 50000;
    int i;
    void Method()
    {
        while(prevModule == nextModule && i < maxIterations)
        {
            //do work
            nextModule = GetRandomModule();
            i++;
        }
    }```

[slender cargo]

also how many max iterations would you let it do?

[celest spoke]

Also everyone im watching seem to have previews of different things to write where as i have to do everything manually. is that also some kind of addon / extension?

[gaunt ice]

up to you really what number it is, i choose 50,000 but can be more or less. How many times should we try before it stops

[slender cargo]

It wants me to put = something after i?

[rich adder]

int i = 0

you have not assigned a value and its a local var so needs init

[slender cargo]

but then surely it wouldn't count up?

Ohhh wait its a while, not an if

yeah that makes sense

only installing the Unity plugin isn't enough

[rich adder]

which part you dont understand? the object that spawns it (spawner) passes its scene reference(Player) to the object spawned

[scarlet skiff]

hmmmm one moment ill try

[gaunt ice]

actually you dont need to loop to find a random thing

int someInts[100];//some ints here
int choices=100;
each time when you get a random value from someInts
int index=rand()%choices;
int val=someInts[index];//swap the value with back
someInts[index]=someInts[--choices];
someInts[choices]=val;

[buoyant knot]

btw ty on the cellular automaton recommendation, Tina. It helped quite a bit

[rich adder]

this is hella confusing for a beginner no?

[gaunt ice]

the basic idea is remove the chosen item from current collection and put it in somewhere (maybe you need to reset it)

i just put it in place

[buoyant knot]

if you need a uniformly randomly distributed item from an indexed collection, you can just select a random index

[rich adder]

true

[scarlet skiff]

is this right?

[swift crag]

Bingo!

[rich adder]

thats one way to do it sure

[swift crag]

One improvement, though.

public GameObject fireballPrefab;

[scarlet skiff]

can i shorten down to this

[swift crag]

you could just make this a public Fireball fireballPrefab;

[hard hornet]

Vector3.zero

[rich adder]

you dont need new Vector3

[swift crag]

now you don't have to do GetComponent<Fireball>() -- Instantiate will just return a Fireball

[hard hornet]

evenb etter

[rich adder]

default for value type is already 0,0,0

in this case

[scarlet skiff]

oh for that i had cuz im likely going to change the spawn point, just have to 0 for now

[rich adder]

oh wait it local var.. nvm

[swift crag]

I would prefer to use Vector3.zero anyway

[scarlet skiff]

lika dis?

[supple jungle]

how to make missing (game object) in arrays null? i tried by comparing tag in every index

                {
                 
                    rockAmount[i] = null;
                }```
but it stays at missing and i cant replace it with another gameobject

[rich adder]

why is it missing in the first place ?
you should use ScriptableObjects instead if you have items in list that destroy

[scarlet skiff]

is the middle of the scene 0, 0 ,0?

[rich adder]

thats the origin of the world

[scarlet skiff]

hmmm
its now spawning the fire balls at the origin and not at the spawner itself

[rich adder]

well yeah you wrote 0,0,0

world pos

[scarlet skiff]

i wanted the local 0, 0 ,0

[rich adder]

if you want the spawner position just pass the spawner position

[scarlet skiff]

oh ye

[swift crag]

I'm not sure if the inspector will update after you set an array item to null

I don't see how this would stop you from assigning a new game object into the array. Gonna need some more context here.

[rich adder]

use a list and remove the element 😈

[supple jungle]

i use destroy() to delete gameobjects then i have fuction that checks if any index in array is null and makes new gameobject

[swift crag]

a destroyed object will equal null

i.e. obj == null will return true

[scarlet skiff]

okay so what the fire ball does now is move in a sinus wave, rotating towards the direction its moving to, but also following the player.

right now however its turns after the player in a sharp manner and feels unnatural.

My solution to this would be to not update the players position every frame, but instead every 10 frames maybe.

Timers and such is also something that confuse me and to time stuff i use DateTime

so the way id solve this rn would be to have an if statement that checks if the DateTime timer is equal to or less than the current date (if its now or already happened), and if it has, it updates the players position but also sets the DateTime timer to current date + 0.5seconds, would this approach work?

[swift crag]

Time.time is the time since game start in seconds

you can use that basically identical to how you're currently using DateTime

[scarlet skiff]

is it like best practise to use that?

[swift crag]

you generally care about in-game time, not about real world time

for example, if you pause the game, cooldowns shouldn't be progressing

[rocky canyon]

unless u want to shame the player for not playing for X: amount of time 😄

[arctic ibex]

Okay so I have this piece of code on my player to stop them from colliding with the fence tile map, and it's still colliding, do I need this code on the tilemap too? or have I written it wrong?

Physics2D.IgnoreCollision(fence.GetComponent<Collider2D>(), GetComponent<Collider2D>());

It's in void start by the way

wait nevermind I forgot to actulaly asign the tag

lol

[scarlet skiff]

ohhh

i see

but otherwise the structure would work, ye?

dang cant use add seconds tho

or ill just do + the number

like + 0.5

[green island]

im using public MonoScript attack; for getting an interface into an Scriptible object but when i trie building the game i get this error

error CS0246: The type or namespace name 'MonoScript' could not be found (are you missing a using directive or an assembly reference?)```

[scarlet skiff]

something like this i suppose

[rich adder]

show the full error stack

are you not getting underlines in your IDE btw

[swift crag]

Time.time is a float.

So, yes, you just add a number to it.

There's no need to add all those (float) casts.

[verbal dome]

MonoScript is in the Editor namespace only

It won't work in a build

[green island]

is there another way to make it work in build?

[swift crag]

What are you trying to accomplish?

this is an obvious XY problem

[verbal dome]

Why can't you reference a ScriptableObject?

[green island]

to link an interface into an scriptible object through the editor

[verbal dome]

What would you do with that interface

[swift crag]

a MonoScript is the actual script asset. it has nothing to do with the classes defined in that script

I don't understand what "linking an interface" would entail

Are you trying to serialize a field of an interface type?

[ivory bobcat]

I don't think interfaces are accessible from the inspector without customizing the editor

[swift crag]

You can't do that by default. Unity will only serialize types deriving from UnityEngine.Object

(along with some other types like float/int/etc., List<T> where T is serializable, and a few others)

[green island]

every character has a diffrent attack so i need to add an interface to the player if this character is used

public class TestAttack : MonoBehaviour, IAttack
{
    public void LeftClick()
    {
        Debug.Log("Left");
    }

    public void RightClick()
    {
        Debug.Log("Right");
    }

    
}``` this is the interface im testing with

[iron wind]

Use OnValidate to check if whatever was assigned to your field implements the interface and if it doesn't set it to null and throw error

You need to put ScriptableObject/MonoBehaviour as the type though

[ivory bobcat]

That's a class that implements an interface IAttack

[green island]

this is IAttack:

public interface IAttack
{
    void RightClick();

    void LeftClick(); 
}```

[verbal dome]

You can't "add an interface", but you can add a component that implements that interface.

So are you trying to store the type of the interface in the ScriptableObject?

[green island]

yeah i want to link an component that inpliments the class into the SO

[green island]

yes but if i use IAttack as the type i cant add it in the editor

[ivory bobcat]

The component would only be a prefab though.. maybe the referenced object should also be an SO?

Or a regular class

[swift crag]

You have a few options here.

You can make an abstract Attacker class that derives from MonoBehaviour

The player could then derive from Attacker

This starts causing problems when you want to have lots of different interfaces, though

[green island]

i have just one interface

[swift crag]

You can also split the "attacker" logic out from the player component and into a separate component.

[verbal dome]

One way is to make an enum in the SO and map that enum value to a type for the component to be added

[swift crag]

So you'd have a Player component that has no idea about attacking itself

and then a separate component that, again, derives from an abstract class with the attack methods on it

This is what I've done in my game: lots of small modules

It's a composition-based approach.

[rocky canyon]

can i somehow inspect this list as i could with a list of gameobjects

  void AddOrRemoveSelectable(ISelect selectable)
    {
        //if its in the list remove it
        if(selected.Contains(selectable))
        {
            Debug.Log("Removed Selectable");
            RemoveSelectable(selectable);
        }
        else
        {
            Debug.Log("Added Selectable");
            AddSelectable(selectable);
        }
    }``` im adding and removing, and debugging was a PITA

i remember something about serializeable , or maybe odin's free attribute asset thing, its on teh tip of my tongue and i cant think of it

[swift crag]

There are several assets that let you serialize interface-typed fields.

notably, Odin Inspector can do that with one of its features, iirc

[rocky canyon]

is the odin one the way to go?

i would assume yea

[swift crag]

I've never used Odin, though.

[rocky canyon]

they have that free version that does this?

i think so

[ivory bobcat]

It's private so it's not visible - relative to access modifiers.

[rocky canyon]

yea, even when its public its not visible.

i just made it private b/c of that

and i was getting editor draw errors

[green island]

yeah i have one attack script that does some checks if it passes it gets the component from the player that comes from IAttack and calls the func now i need to add the interface on the start dependeing on the scriptible objects on the player

[ivory bobcat]

Yeah, interfaces are not shown in the Unity inspector

[rocky canyon]

first time ive used a list with something other than gameobject

[swift crag]

If the player has a component that implements IAttack, then i'd just go ahead and turn IAttack into an abstract class

[rocky canyon]

ive been spoiled by seeing the dropdown in teh inspector 😅

[swift crag]

public abstract class Attack : MonoBehaviour

Since this derives from MonoBehaviour, Unity can serialize it.

[ivory bobcat]

Maybe reference a base class that's inherited and implements the Interface. You'd be able to show it's members.

[swift crag]

It's a very annoying hangup. I wish there were some way to promise that I'm always going to be referencing a unity object.

[ivory bobcat]

Assuming there's a common base class

[rocky canyon]

theres not one yet, but i could make that alteration if need be

basic as beans

[ivory bobcat]

Yeah, so reference a list of type friendly selectable

It would then be available from the inspector

[green island]

how can i link it in the so?

[rocky canyon]

👍 i also have an NPC version

[swift crag]

the scriptable object is an asset

[rocky canyon]

i may use two lists.. with those specific types

[ivory bobcat]

Maybe have a base class called Selectable

[swift crag]

assets can't reference scene objects

[ivory bobcat]

Where all types of selectable would inherit - it would dictate what's shown in the inspector

[swift crag]

it would also not be useful to reference the Attack component on the player prefab

since that would always be the player prefab's Attack component

It sounds like the Player component should be able to tell you about its Attack component

[verbal dome]

@rocky canyon There's always the ugly hack of serializing it as Component and then casting it to your interface type when used

[swift crag]

or maybe even components, if you have several attacks

[swift crag]

hey, it's better than serializing a UnityEngine.Object

sometimes I click on a field of that type and I get hit by a massive wall of choices lol

every single asset in the entire project

[rocky canyon]

i may do something temporary until i get the selection and deselection working.. currently its working but i gotta guess whats in the list (as i suspect)

list of a base class like u mention

[green island]

i want to have var Attack in the so within the attack component is linked so i can add it

[swift crag]

Okay, but what is that field going to store a reference to?

[ivory bobcat]

You could reference them as type GameObject and they'll be visible to the inspector

[verbal dome]

I hope interfaces become more inspector-friendly in the future. SerializeReference is dope but I want more

[iron wind]

You "can" serialize an interface by serializing the MonoBehaviour directly. The downside is you have to cast the value (so you should probably cache it) in runtime.

interface IMyInterface {
    void DoAction();
}

class MyImplementer : MonoBehaviour, IMyInterface { } //code etc..

class SomeReferenceThing : ScriptableObject  {
    public MonoBehaviour TheScript;
    public IMyInterface Value => (IMyInterface)TheScript;

    void OnValidate() 
    {
        if (TheScript != null && TheScript is not IMyInterface)
        {
            Debug.LogError($"{script.GetType()} does not implement {nameof(IMyInterface)}!")
            TheScript = null;
        }
    }

    void Update()
    {
        Value.DoAction();
    }
}```

[swift crag]

Your scriptable object is an asset. It can't reference scene objects.

I don't understand your design.

I almost always have references to scriptable objects

scriptable objects don't have references to me

[rocky canyon]

For plain C# classes you could also think about using a reflection-based approach by storing a string representation of the class and interface and then using the Activator class from the .NET framework to create instances when you need them.

[iron wind]

Another downside to the method I linked is that the inspector will not filter your interface properly

[rocky canyon]

this doesnt sound good

[verbal dome]

So you want a variable that dictates which Attack component is added to the character?

[rich adder]

reflection is slow af ye

[swift crag]

https://openupm.com/packages/net.tnrd.serializableinterface/ gives you a nice interface at least (ha-ha)

[green island]

no i need it to add it to the player

[ivory bobcat]

Or referencing the base class (it doesn't need to inherit MB).
I'm guessing the Issue is that they don't have a base class.

[rocky canyon]

ohh cool thx

[verbal dome]

You need what to add what to the player

I just said

added to the character
So I'm confused

[iron wind]

Not the same thing though, one requires an implementation and the other is the abstraction

[rich adder]

why isn't this built in..

[iron wind]

class BaseClass1 : IMyInterface
class BaseClass2 : IMyInterface

Can't reference either which is why you want interface in the first place

[ivory bobcat]

Inheriting MB would require there to be an instance in the scene.. unless you're really wanting to make many prefabs.

[green island]

each chracter has a scriptibleobject and you can choose one on the start in the so all stats for the character are saved and i need to add a script to handel the attacks but the gamobject stays the same for each character and movement just the attacks and model change

[iron wind]

Yeah in this case it's a bit of a weird case as you typically want to ref an SO instead 😅

[green island]

the so is refed on the player

[iron wind]

you can put functions in ScriptableObjects too

[green island]

how? so when i create one i can paste code into it?

[verbal dome]

A scriptableobject is a C# class and you can add methods and other functionality to it as you like

[polar acorn]

You just... type the code into the script

[stark girder]

what is empty Vector3int is it equal to null?

[verbal dome]

Most of people use SO's as just data containers but they can also be instantiated and can have logic in them

[polar acorn]

it's not any different

[swift crag]

I don't understand how this would help you "save stats"

[rich adder]

value types cannot be null

default vector3int.zero

[polar acorn]

Default Vector3Int is (0,0,0)

[swift crag]

scriptable objects are assets. the game can't modify them on disk.

[green island]

these are the default stats how can i add code here

[swift crag]

Changes will stick around in the editor for a bit

but that's not how it's going to work in the built game at all

[stark girder]

thanks

[verbal dome]

It is a struct and all its member values will be their default. It has three ints and int's default is 0, so it is 0,0,0

[swift crag]

surely you've written code in a MonoBehaviour before..

you don't shove the code into the inspector. you just..write it. in the class.

[green island]

yes but i cant open this

[polar acorn]

Open the file, add code to it

[ivory bobcat]

Reference an SO that implements the wanted interface
The SO would implement the method and you'd get modular access to it by using your character stat this other SO

[polar acorn]

Open the script

the one that you made that defines this asset

not the asset itself

Hi, i have a problem when launching my C# code through Unity as it write : "No installed .NET SDK was found on the computer. If it is installed, make sure it can be found through the PATH environment variable. C# Dev Kit does not work without a supported version of SDK. After installing the SDK, you need restart the VS Code session, or the computer."
But i open it only with VSCode i don't have that

[iron wind]

Like this:

public class GameAction : ScriptableObject { 
  public virtual void DoAction() { }
}

public class AttackAction : GameAction {
  public float SomeValue;  
  
  public override void DoAction() {
  Debug.Log("boom");
  }
}

Someone have a solution ? (i'm on linux, I've installed Mono, .net, having this in my bashsrc : export PATH=$PATH:$HOME/dotnet)

[green island]

but if i add it directly every instance i create from the so it will have the same code

[remote sequoia]

You need to install .NET SDK

[iron wind]

Just make more classes that implement the behaviour you care about

[remote sequoia]

You can download with unity hub

[rich adder]

what

[ivory bobcat]

Have many SOs.
For example: there may be different varieties of Character Stat SO and many varieties of an SO that inherit the base Ability SO where Character would reference the base Ability SO.

sorry for AI voice, i had no mic that week xD

[remote sequoia]

At first i thought it was something else, yes sorry

[stark girder]

if default value is 0,0,0
that why does this not even run
shouldnt the i be 0,0,0?

[swift crag]

what if activeFires is empty?

[rich adder]

Op is on Linux Visual Studio isn't a thing

[swift crag]

the default value isn't in an empty list. nothing is in an empty list.

[verbal dome]

If nothing logs then either this code isn't running or activeFires is empty

[swift crag]

Vector3Int myVec;

myVec can never be "empty". there's exactly one Vector3Int here, and it's stored in myVec. If you don't assign anything else to it, then myVec will store the default value.

List<Vector3Int> vectors = new();

vectors can contain zero, one, or many Vector3Int values.

[remote sequoia]

I prepared such a spawn method, but I have a problem. For example, in the 3rd wave, there are only 3 a prefabs or 3 b prefabs. What should I do to make this happen randomly too? For example, in the 3rd wave, 2 prefabs A and 1 prefab B will be spawned randomly.

[swift crag]

just pick randomEnemy inside the loop

[stark girder]

yes I get that but should it run at least once as its not empty?

[swift crag]

what if it is empty?

why do you think activeFires isn't empty?

[remote sequoia]

it isnt enough

let me show

[swift crag]

the current code is not enough, yes

[stark girder]

but what it is when its empty how can I chceck that its empty

[swift crag]

it picks randomEnemy once and then spawns that enemy many times

[swift crag]

assuming that's a List<Vector3Int>, just do activeFires.Count == 0

[swift crag]

that's why you need to pick randomEnemy every time the loop runs.

[stark girder]

thanks that should do

[remote sequoia]

Like this. İn the one wave, all enemys are same

[remote sequoia]

How i can extend my code

[swift crag]

Yes. Because you're picking randomEnemy only once.

[swift crag]

[swift crag]

Nothing in there.

[errant spear]

that's my workspace json like you've asked

[swift crag]

Now examine the user settings. There's probably more stuff in there.

[remote sequoia]

thanks

[swift crag]

I'd definitely do a restart before digging around any further, though!

do the easy step first

[errant spear]

restarted but no

here's user json

[rich adder]

can you show which .net command you used to install

[errant spear]

sudo apt-get update && sudo apt-get install -y dotnet-sdk-7.0

[rich adder]

and did it say it installed ok , no errors?

this is french 🤷‍♂️

[errant spear]

wait i'll trad it

[rich adder]

don't need the whole log you can just tell me

[errant spear]

[errant spear]

I don't know what should be considered as an error so i prefer to give it like this

[rich adder]

says you already have sdk

type dotnet --list-sdks in terminal

[swift crag]

It sounds like the C# extension is looking in the wrong place.

[swift crag]

ah, hm

[rich adder]

weird, not even error if command is working or not..

[swift crag]

or there are zero SDKs!

[errant spear]

That's really strange

[errant spear]

Yay :D

[swift crag]

Here's a thought

which dotnet

what does that give you?

[swift crag]

I bet that you got dotnet from one repository and the dotnet SDK from another repository.

https://learn.microsoft.com/en-us/dotnet/core/install/linux-package-mixup?pivots=os-linux-ubuntu#whats-going-on

Check this out

The fix is going to be to tell apt that you much prefer Microsoft's repository for anything dotnet related

(or to just remove the Microsoft package feed entirely)

[scarlet skiff]

i want the sine wave to be less apparent/weaker valleys n tops when coming closer to the player

[rich adder]

nice code comments

[shrewd swift]

i wish i knew where they come from

[scarlet skiff]

so t odo that i introduces the distance variable

and athe closer you are, the smaller the number after division becomes

which should make the waves less intense

[timber tide]

time to take out your pen and paper

[errant spear]

i can't find /etc

like through commands i have

but not manually

[shell sorrel]

would create a 0 to 1 number based on distance, and multiply the sin by it

[swift crag]

are you new to using linux?

[errant spear]

Yes, for my studies i have a linux device

[shell sorrel]

inverselerp can be used to take a range of distance and get your 0 to 1 multplier from it

[errant spear]

so not everything is clear for me

[timber tide]

could really just use an animation curve and multiply by that

and have more freedom on the editor vs hard coding values

[swift crag]

That's the ticket.

for example...

float distanceFactor = Mathf.InverseLerp(5f, 20f, distance);

You could then plug this into an animation curve

float strength = curve.Evaluate(distanceFactor);

[timber tide]

also speaking of animation curves is there a way to steal the animation curve from line renderer

that one is like extra polished

Rather, I want it because it clamps 0 to 1

[quick ruin]

If the bool manaOn == false it still runs and changes the material color. is this just bugged?

[ivory bobcat]

How do you know it's false?

[quick ruin]

set it to public and viewed in inspector

[ivory bobcat]

Well, it's definitely true if the code is occurring.

[swift crag]

what is manaBlue? a reference to a material you assigned in the inspector?

[quick ruin]

yes

[swift crag]

perhaps you have multiple objects using the material?

and multiple copies of this component in various places?

[ivory bobcat]

Maybe log thiscs Debug.Log($"Mana On: {manaOn}", this);

[shell sorrel]

how is your reference to manaBlue created?

[ivory bobcat]

Assuming this isn't spamming the console, click the message when it's supposed to be false but not.

[void dawn]

heelo

[quick ruin]

its returning false and still running it for the false ones

im so lost lol

[void dawn]

i was following a tutorial

https://www.youtube.com/watch?v=-GWjA6dixV4

[swift crag]

So you do have many components of the same type.

[void dawn]

as i was trying to make a fps

[ivory bobcat]

Click the message. What gets highlighted?

[void dawn]

but something broke my game

[polar acorn]

Okay, now take that log and put it inside the if condition. Do you still see it printing false anywhere

[void dawn]

i will send my project , can you guys help me with this one

fuck i cant send my project

what do i do

[shell sorrel]

no one is going to review a whole project for you, break down the problem smaller and figure out what part is broken

[modest dust]

describe what the issue is

[ivory bobcat]

Maybe just explain what's not working as expected and what step in the video you're at relative to time.

[swift crag]

so a very important thing here is that you're referencing material assets

when you modify them, the changes will persist

[void dawn]

you see unity changed since this video was made and im on the last steps of it

i cant add the start scripts to the main menu part , this is vital since it would make the whole thing work

[shell sorrel]

if you are changing the material at runtime you will want to instead make a copy of the material then assing it to the renderer

[void dawn]

also i think something is wron with the camera

[swift crag]

I think you need to reference a renderer, and then do myRenderer.material.SetColor(...)

.material makes a copy of the material for the renderer if one doesn't already exist.

[void dawn]

because its centered in the characters face

[shell sorrel]

that way your modificitons will not effect multiple objects at once and they will not dirty the state of the mateirals in your assets folder

[ivory bobcat]

Are you sure you're not trying to place an instance from the scene onto the prefab? (assuming you're accidently looking at the prefab button)

[void dawn]

what exacly do you mean im new to this

[ivory bobcat]

What time in the video are you unable to copy?

[void dawn]

4:26

[ivory bobcat]

Can you show your hierarchy and that you've selected the three buttons?

[void dawn]

sure just wait a second

[rocky canyon]

I found a solution that works for me.. (only need it to debug at times)

NaughtyAttributes + Text Area

i casted them as Monobehaviours, then debug the names

https://assetstore.unity.com/packages/tools/utilities/serialize-interfaces-187505
i tried using this first, but i couldn't get the list to be visible, the closest i got was a drop down with broken elements inside, (just the menu bar and the three dots to drag around)

then i realized i hadn't imported naughtyattributes, and i love that asset, so i made it work w/ that instead with the little mini-debug-string-window

lol

[timber tide]

I've tried some packages but I've just surrendered to not using interfaces this way

unity really needs editor support updates

[rocky canyon]

ya, troublesome to say the least. there was a bug yesterday and i couldn't tell what was happening, so i wrote alot of debugs just to visualize what was happening

once i get the bugs worked out, i can get rid of this completely..

but swapping to interfaces really cleaned up my code, so im fine with them 🙂

went from something long and nasty like this

to a much more legible

                if(!selected.Contains(selectable))
                {
                    AddSelectable(selectable);
                }
                else
                {
                    RemoveSelectable(selectable);
                }

                // first we need to know if this is already selected, if it is do the following

                // we need to check if we start dragging

                // if after so long our focused raycast position hasnt changed we can assume we want to open the units menu

                // we also need to check if we're holding down

                // if was a single quick click then we just need to deselect

                // if it wasn't selected we can just assume we want to select it

            }
            else
            {
                // we clicked something that wasn't selectable

                // are we selected?

                // if we are what happens?

                // if we're not what happens?
            }``` still got a crazy interaction system to setup 😅

[dusty coral]

how to filter gameobjects in the scene based on components?

[rich adder]

the whole scene?

[dusty coral]

ye

[languid spire]

search using t:

[rich adder]

or you mean code?
FindObjectsOfType

its kinda slow so you should prob not use it in something like Update

use awake/start to store them

[dusty coral]

no i mean like from the hierarchy

[rich adder]

oh then what SteveSmith said

[dusty coral]

cause theres a random collider i cant click on

i dont know where its from]

[rich adder]

t:Collider

[dusty coral]

nice

[unborn gale]

hi

I had a question I was desprate to get an answer for

[rich adder]

if you were desperate why haven't you posted it yet ?

[unborn gale]

#archived-lighting

[rich adder]

this is a code channel

[rocky canyon]

lol

[unborn gale]

am pretty sure it has code involved

[frosty hound]

It's not, don't crosspost.

[rich adder]

oh wait 2d lights doesnt have that

[frosty hound]

And if you think it's code related, then remove it from there and ask here with the code you're using for it.

[unborn gale]

ama just ignore you

am immagrating to #💻┃unity-talk

[frosty hound]

You will be warned if you crosspost, your question is and belongs in #archived-lighting. Stop being a child.

[quick ruin]

is GetChild and Find("") the same performance?

[rocky canyon]

doubtful.. GetChild is going to be constrained to just the parent and all its children

Find() is gonna search the entire Hierarchy

[river roost]

They probably meant this
https://docs.unity3d.com/ScriptReference/Transform.Find.html

Find is slower, as it has to compare strings

but I don't think it's going to be noticable unless you're doing it a lot

[ivory bobcat]

Get child acquires the object by index https://docs.unity3d.com/ScriptReference/Transform.GetChild.html
whereas Transform Find would search by string (it's name) https://docs.unity3d.com/ScriptReference/Transform.Find.html

Assuming you aren't referring to GameObject Find which searches the entire hierarchy.

[meager sentinel]

Idk why but i get this error on VSC sometimes, but other times (like rn) the IDE does work, what is happening?

[rocky canyon]

its faster to search thru a specific Parent

but i figured as much.. (very very little difference)

[faint osprey]

{
    public CinemachineVirtualCamera VC;
    public GameObject player;
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(Delay());
    }

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

    }

    private IEnumerator Delay()
    {
        yield return new WaitForSeconds(3.9f);
        Vector3 deltaPos = player.transform.position - VC.transform.position;
        float timePassed = 0;
        while (timePassed < 1f)
        {
            timePassed += Time.deltaTime;
            VC.transform.position += deltaPos * Time.deltaTime;
        }
        VC.transform.position = player.transform.position;
        VC.Follow = player.transform;
    }``` why is my VC not moving towards my player

[ivory bobcat]

What if you had 100 children?

[rocky canyon]

lol, not sure, i did use about 20- 30 children.. w/ alot nested

but 100s or 1000s idk 😄

[ivory bobcat]

If Unity uses a dictionary under the hood, it should be pretty quick with the hashing else if they're comparing names for a list... the number of elements might matter a lot.

[polar acorn]

Is this object destroyed or disabled after the coroutine starts

[rocky canyon]

this was what i tested it on

[faint osprey]

no its active in the scene

[rocky canyon]

with the highlighted one holding the Test script i was hunting for

[faint osprey]

however it is being used in a timeline

[rocky canyon]

ahh, i used GetComponentInChildren not Find.

[polar acorn]

If it's already in a timeline why are you manually timing this

[faint osprey]

cause theres certain things with a virtual camera which u cant control in a timeline

[ivory bobcat]

Grand children do not seem to be evaluated. Good test either way 👍

[rocky canyon]

oh cool, TIL

[polar acorn]

I don't know too much about Timeline but I'm pretty sure it's more than capable of affecting an object's position

[rocky canyon]

i just dont ever wanna seach with strings anymore 😄

i try to avoid it lol i've even stopped using CompareTag()..

much prefer a TryGet and a component now

[faint osprey]

yeah but you cant set the follow target

[faint osprey]

i also dont know where the player is gonna be

[polar acorn]

Can't the timeline call functions in a script? You could put in a function that sets the follow

[rocky canyon]

isnt the timeline like a glorified animator? couldn't u track the player thru a script, and maybe control that script via the timeline?

[rocky canyon]

ya i was thinkin same as u

[polar acorn]

Seems like the issue is likely that the Timeline is overwriting the object's position, so this coroutine changes it, but the Timeline immediately changes it back

[faint osprey]

well i deleted the timeline and its still not moving

its just skipping to the position instantly

[polar acorn]

Try putting some logs in the coroutine, before and after the yield, inside the while, and after it

[faint osprey]

i have everything runs as it should

[polar acorn]

Then it would seem that something else is setting the transform

[rocky canyon]

Phantom code

[faint osprey]

theres defitnly not

could it just be happening so quickly that it looks instant

[polar acorn]

Try logging the camera's position before the while, during the while, and after the while

Make sure to actually include which one is which

See if the position actually changes

[faint osprey]

it does

its just jumping from the start location to the end

not gradually changing over 1 second

like it shod

[polar acorn]

Oh, right, that's because you're doing it all in one frame

Your only wait is at the beginning

It does the rest instantly

[faint osprey]

but its in a while loop

so shod update every time the while loops

[polar acorn]

Yes, that's why it runs instantly

[polar acorn]

Yes which is immediately

[faint osprey]

what it does all loops in one frame

[polar acorn]

Yes that's how all loops work

The only code that exists is that loop until it's finished

If you want to run one iteration and then wait a frame you should actually wait a frame

yield return null

[faint osprey]

but that at the end of the loop?

[polar acorn]

in the loop

after you do whatever you want the loop to do

[swift crag]

(at the very end of the loop body, yes)

certainly not after the loop body

[ivory bobcat]

You probably forgot to yield in the loop

[faint osprey]

that works cheers guys

    {
        yield return new WaitForSeconds(4f);
        Vector3 deltaPos = player.transform.position - VC.transform.position;
        float timePassed = 0;
        while (timePassed < 1f)
        {
            timePassed += Time.deltaTime;
            VC.transform.position += deltaPos * Time.deltaTime;
            VC.transform.position = new Vector3(VC.transform.position.x, VC.transform.position.y, -35);
            VC.m_Lens.OrthographicSize = -45 * Time.deltaTime;
            yield return null;
        }``` im trying to change the orthographic size as well now but thats not changing for some reason

[polar acorn]

Well, Time.deltaTime isn't likely to change much from frame to frame, so you're setting it to the same value every frame

Why are you trying to set the orthographic size to a constant times deltaTime anyway

[ivory bobcat]

You aren't decrementing it. You're setting it to negative forty five multiplied by whatever value delta time was that frame.

[faint osprey]

i want it to go from 50 to 5

and deltapos works in a similar way so i thought that would

[polar acorn]

So then why are you setting it to -45 divided by your framerate

[ivory bobcat]

... = 50 - 45 * an accumulating variable relative to time

[swift crag]

perhaps you were looking for the += operator

[faint osprey]

oh it was meant to be =- 45

[polar acorn]

No it doesn't. You're adding a value to that. You're setting the orthographic size to a constant

[faint osprey]

i put a space on accident

[polar acorn]

That's the same thing you just typed

= - and =- are not different

[faint osprey]

what how the minus was connected to the 45 before and this time its on the equals making it a decrement

[faint osprey]

yeah

[polar acorn]

=- is not a thing. It's the same as = -. You are probably thinking of -=

[quick ruin]

can you invoke while passing a var?

[slender nymph]

No

[swift crag]

Invoke must be given the name of a method to call.

It looks like you just want to call the method directly...

[wintry quarry]

Use a coroutine instead

[faint osprey]

oh yeah

its still not changing tho

[swift crag]

well, show us the code you wrote

[faint osprey]

    {
        yield return new WaitForSeconds(4f);
        Vector3 deltaPos = player.transform.position - VC.transform.position;
        float timePassed = 0;
        while (timePassed < 1f)
        {
            timePassed += Time.deltaTime;
            VC.transform.position += deltaPos * Time.deltaTime;
            VC.transform.position = new Vector3(VC.transform.position.x, VC.transform.position.y, -35);
            VC.m_Lens.OrthographicSize -= 45 * Time.deltaTime;
            yield return null;
        }```

[swift crag]

what isn't changing?

[faint osprey]

VC.m_Lens.OrthographicSize

[swift crag]

look in the inspector as the code runs. i see no reason for it to not go down over time

[faint osprey]

it just stays at 50

[swift crag]

is the code even running?

[faint osprey]

yes it is

cause evrything else is working

[swift crag]

and if so, does logging VC.m_Lens.OrthographicSize show the value is changing?

[faint osprey]

yeah its going down 0.4

[swift crag]

i don't know how to interpret that. is it going down from 50 to 5, or is it just constnatly resetting to 50 and then getting reduced?

[wintry quarry]

LensSettings is a struct.

You have to do this:

LensSettings lensSettings = VC.m_Lens;
lensSettings.OrthographicSize = -45 * Time.deltaTime;
VC.m_Lens = lensSettings;```

[swift crag]

shouldn't that be a compile error?

[wintry quarry]

One would expect so...

[swift crag]

assuming that m_Lens is a property

but it isn't. it's a field

I see no problem with doing that.

[wintry quarry]

Oh I see

You're right

[swift crag]

is the camera actually in orthographic mode?

[faint osprey]

that didnt work

[ivory bobcat]

We need the response to this question #💻┃code-beginner message

[faint osprey]

from 50 to 5

[ivory bobcat]

So it's working

[wintry quarry]

This question is very important too @faint osprey

[faint osprey]

its a virtual camera so yes cause theres no other option

[faint osprey]

no

[wintry quarry]

If it's a perspective camera you need FieldOfView not OrthographicSize

[faint osprey]

i thought u were asking what u want it to do

[wintry quarry]

There are two options, orthographic or perspective (orthographic checkbox OFF is perspective)

[faint osprey]

i dont think there is

[ivory bobcat]

It looks like the code works in decreasing the value. The behavior just isn't what you're needing.

[swift crag]

expand "Advanced"

[swift crag]

By default, the virtual camera will use whatever mode the main camera is using

Okay, so it's set to force the main camera to be orthographic

does changing the ortho size actually do anything?

as in, just changing it by hand

[faint osprey]

yeah zooms in and out thats why i set it to 50 cause it was 5 but i want it to zoom in

[swift crag]

I feel like you've got a second virtual camera that's following this virtual camera.

[topaz pendant]

OrthographicSize doesn't seem to be a parameter you can manually change

[swift crag]

that would neatly explain all of the behavior we've seen

[swift crag]

no, you can. it controls how large the camera's sensor is

[topaz pendant]

Oh okay

[swift crag]

It's the height that the screen takes up in the game world

[faint osprey]

nope

[swift crag]

well, it seems like changing the orthographic scale of the camera is doing nothing, so something is wrong.

I would verify that you're actually moving the camera you think you are:

Debug.Log("Moving", VC);

[faint osprey]

its changing just a very tiny amount

[swift crag]

click on the log entry and make sure it selects the correct thing

[swift crag]

so if you start the game and change the orthographic size, it works correctly (going from 50 to 5 makes you zoom in by 10x)

but if you let this coroutine change the orthographic size, the orthographic scale still drops from 50 to 5, but the camera barely zooms?

[faint osprey]

if i change it manually yes

[topaz pendant]

Do you have any errors ?

[swift crag]

Share the entire script.

[faint osprey]

        {

        VC.transform.position = player.transform.position;
        VC.Follow = player.transform;
    }
}

[faint osprey]

no

[swift crag]

oh well that definitely isn't going to work now, since you aren't assigning lensSettings back into the camera

[faint osprey]

ive just done that now

didnt work

[ivory bobcat]

I wonder if this occurs whenever the field changes (via poll) or explicitly only when the vcam becomes live? It's obviously not a property.
https://docs.unity3d.com/Packages/com.unity.cinemachine@2.1/api/Cinemachine.CinemachineVirtualCamera.html

[topaz pendant]

but m_Lens is a struct

[swift crag]

It's a field.

I have to wonder if another camera is being blended to.

[topaz pendant]

when you do var lensSettings = VC.m_Lens;, you copy the content of m_Lens in a local variable

[ivory bobcat]

These settings will be transferred to the Unity camera when vcam is live
I'm assuming once or would it do so constantly with a poll?

[swift crag]

yes, which is why I said it wouldn't work above

[faint osprey]

VC.m_Lens = lensSettings; i added that after u said it

but its not working

[swift crag]

it constantly updates

[swift crag]

we need to rule out any really weird interference from any other code that we can't see.

[topaz pendant]

Okay bcause you didn't write it in the above code

[swift crag]

After the coroutine terminates, what is the orthographic size of the camera?

[ivory bobcat]

Remove that

[swift crag]

Screenshot its inspector after the coroutine is done.

50 in editor but if i debug it its like 49.647

[swift crag]

I thought you said it went down to 5.

So it doesn't go down to 5. It goes down to 49.647 and sits there.

[faint osprey]

no i said thats what i want it to do

[swift crag]

Show me exactly what your code looks like right now.

[ivory bobcat]

So it didn't go down.

[faint osprey]

wait why

[faint osprey]

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

public class SpawnCutsceneScriptCompanion : MonoBehaviour
{
    public CinemachineVirtualCamera VC;
    public GameObject player;
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(Delay());
    }

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

    }

    private IEnumerator Delay()
    {
        yield return new WaitForSeconds(4f);
        Vector3 deltaPos = player.transform.position - VC.transform.position;
        float timePassed = 0;
        var lensSettings = VC.m_Lens;
        while (timePassed < 1f)
        {
            timePassed += Time.deltaTime;
            VC.transform.position += deltaPos * Time.deltaTime;
            VC.transform.position = new Vector3(VC.transform.position.x, VC.transform.position.y, -35);
            lensSettings.OrthographicSize -= 45 * Time.deltaTime;
            VC.m_Lens = lensSettings;
            yield return null;
        }
        VC.transform.position = player.transform.position;
        VC.Follow = player.transform;
    }
}

[swift crag]

where were you logging the orthographic size?

it's not in the code you just sent
