Are you iterating a list or transform?

I put the objects which have animations on them in a empty parent and now the animations aren't working??

so they gotta be seperated?

rich adder

you need animator

craggy bane

oh on the parent?

hello people, I have another small issue, I'm trying to delete a "grid" from the hierarcy but for some reason I cannot? right click delete or pressing delete from the keyboard does not work, any ideas why that may be the case?

I wanna make my button change color from red to green when clicked and reverse. i tried this but it didnt work

oy, i have a maincamera that is in a secondary scene added additively. But now i want a canvas that has screen space camera in the main scene, but then i can't reference the maincamera across scenes. Are there any workarounds? I despise screen overlay, specially because i animate stuff and then i don't have a reference to the main scene because it is so huge compared to the actual scene

Use debug.log

Hey guys, I have this GameManager script where I save the player progression when he dies and reload the scene. What happens is that if I die and reload the scene its fine, works good. But if I am killing the final boss of the mini game, and I die and the scene is reloaded, all the enemies desappear but not the boss, what could be? https://paste.ofcode.org/x5Tkj3nx55nAee5mvDBgnD

its probably neither when you run that function

#

how ? it doesnt change by itself lol

#

try putting buttonImage.color = Color.red

#

in start for example

#

and see if function works after

it works

How can I change the player's Y rotation to be the same as the cam's Y rotation? I tried setting the rotation directly but it doesn't work

#

I used Cinemachine to make a FP cam

rich adder

#

what do you mean? cause I tried transform.rotation.eulerangels = cam.transform.rotation.eulerangles but it didn't work

alright, it just rotates based on a single digit

#

freezerotation does the trick

rich adder
# autumn briar yes

think you can do something like

var myRot = player.rotation.localEulerAngles;
myRot.y = cam.rotation.localEulerAngles.y
player.rotatation = quaterion.euler(myrot)```

hi guys, wanna make a game but still not too experienced. wanna make a game that basically looks like command prompt, and it asks you questions like age, name, etc. and predicts your future, wanna make it an analogue horror game and when the game says "when your going to die:" it says tomorrow, flashes a name and closes. tried to find a tutorial but cant really find anything

buoyant knot
#

if your whole game is in a command prompt, then unity is not the right engine for you

queen adder
#

ah okay, what can i use?

buoyant knot
#

you don’t need a gameengine for that tbh

queen adder
#

wanna add vhs and background stuff to make it even more scary

buoyant knot
#

idk, but i still don’t think Unity is the right tool for this

autumn tusk
queen adder
#

honestly true, mb

buoyant knot
#

yeah. pygames is probably a good start

autumn tusk
#

pygames really good for multiple windows and stuff like that

rich adder
#

💩

queen adder
#

alright ty

timber tide
#

pygames is aight but you can also just make it in c# without unity

#

assuming you want to use unity later lol

C# is king

but if python works for you do that :p

how can i download autofiller for visual studio

i forgot how

rich adder

what the hell is that lol

umm like gives you options when ur almost done with writing the word

#

idk how explain it

#

not really necessary ig just see some people have it

#

!ide

rich adder
#

or copilot

#

depending which one they have

scenic cipher
#

@safe carbon I believes its in the Visual Studio Installer, Click Modify, then install the "Game development with Unity"

rich adder
#

intellicode is kinda copilot lite

#

follow the IDE config

#

it will work

safe carbon
#

Thank you good sirs

rich adder
#

dont crosspost

#

also this alone isn't helpful to anyone willing to help, you haven't even posted the code with it

smoky niche
#

The code is not necessary, as it's a tilemap collider bug

rare basin
#

then why are you posting this

#

in a code related channel

rich adder
#

then why are you in a code channel

#

posting in multiple code ones none other

void generateTree(float x, float y)
{
//Define tree

    //Generate Log
    int treehieght = Random.Range(minTreeHieght, maxTreeHieght);
    for (int i = 0; i <= treehieght; i++)
    {
        placeTile(LogTrunk, x, y);
        placeTile(Log, x, y + i);

    placeTile(Leaf, x, y + treehieght + 1);
    placeTile(Leaf, x, y + treehieght + 2);

}
#

It places like 7 logtrunks

rich adder
#

so what is treehieght

#

not even sure what this code snippet alone does

minor roost
#

its hieght of tree

rich adder
#

i see a leaf lookin like a triangle or sum

minor roost
#

want full code

rich adder
#

well no guarantee I can be of help but at very least post the whole script maybe someone knows

minor roost
#

when placetile happens with log trunk

#

7 log trunks place inside one place tile

rich adder
#

well yeah you never increase by i

#

which way is supposed to spread?

#

your x y stay the same why would it not spawn in same spot lol

minor roost
#

lol

#

so hows it supposed to look like

rich adder
#

you tell me

#

what is Log vs Log Trunk ?

minor roost
#

log trunk is bottom

#

log is middle

rich adder
#

so you only need 1 put it outside the loop

# 
            placeTile(LogTrunk, x, y);
for (int i = 0; i <= treehieght; i++)
        {

            placeTile(Log, x, y + i);
        }
       
        //Generates Leaves
        placeTile(Leaf, x, y + treehieght);
        placeTile(Leaf, x, y + treehieght + 1);
        placeTile(Leaf, x, y + treehieght + 2);
minor roost
#

TY XD

rich adder
#

or actually make it only place it if its first iteration

#

this way your placetile log doesn't run first iteration

#

you dont want a log inside a trunk log

minor roost
#

ty

rich adder
# 
for (int i = 0; i <= treehieght; i++)
        {
            if(i == 0){
              placeTile(LogTrunk, x, y);}
            else {
              placeTile(Log, x, y + i);}
            }
       
        //Generates Leaves
        placeTile(Leaf, x, y + treehieght);
        placeTile(Leaf, x, y + treehieght + 1);
        placeTile(Leaf, x, y + treehieght + 2);```

hi, how can i use the polygon collider to see if its collide with another object?

image.png
#

i can't find an example on google

rich adder
#

OnCollisionEnter2D

#

you need at least 1 rigidbody between the two collisions

hidden sun
#

so i need to add rigidbody on it

rich adder
#

either this one or the one you are colliding with

#

also depending if you want Collision or just a Trigger

hidden sun
#

Trigger

#

so i should use OnTriggerEnter2d

rich adder
#

if you dont want that shape to be solid

#

use trigger

hidden sun
#

ty

rich adder
hidden sun
#

2 static rigidbody so i think it will be ok

slender nymph
#

incorrect. notice how static trigger and static do not produce a trigger message

#

nor does static trigger and static trigger

rich adder
hidden sun
#

so i need a non rigidbody and a rigidbody

rich adder
#

like I said before , no you only need 1 rigidbody between two colliders

slender nymph
#

i would also like to point out that trigger/collision messages will not tell you if the object entirely overlaps the other object as was your goal the other day

hidden sun
#

yes, but that is a lil bit hard.. because i have the same object

#

both objects use the same prefab

overlaps

slender nymph
#

why

autumn tusk
#

how do i get an animation to change states on collision via the animation controller

hidden sun
#

its a rule that the plane can't overlap

slender nymph
#

your overlap points can get you that info

#

if they don't hit anything or if they hit another plane object then they cannot be placed, it's that simple

rich adder

how do i define a parameter for the animation controller

how could i make sorting order of leaves 1

#

void generateTree(float x, float y)
{
//Define tree

    //Generate Log
    placeTile(LogTrunk, x, y);

    int treehieght = Random.Range(minTreeHieght, maxTreeHieght);
    for (int i = 0; i <= treehieght; i++)
    {
        placeTile(LogTrunk, x, y);
        placeTile(Log, x, y + i);
    }
   
    //Generates Leaves
    placeTile(Leaf, x, y + treehieght);
    placeTile(Leaf, x, y + treehieght);
    placeTile(Leaf, x, y + treehieght + 1);
    placeTile(Leaf, x, y + treehieght + 2);
    placeTile(Leaf, x, y + treehieght + 3);

    
    placeTile(Leaf, x - 1, y + treehieght);
    placeTile(Leaf, x - 1, y + treehieght + 1);
    placeTile(Leaf, x - 1, y + treehieght + 2);
    
    placeTile(Leaf, x - 2, y + treehieght);
    placeTile(Leaf, x - 2, y + treehieght + 1);

    placeTile(Leaf, x + 2, y + treehieght);
    placeTile(Leaf, x + 2, y + treehieght + 1);

    placeTile(Leaf, x + 1, y + treehieght);       
    placeTile(Leaf, x + 1, y + treehieght + 1);
    placeTile(Leaf, x + 1, y + treehieght + 2);

}

slender nymph
#

if your goal is to change the sorting order of your tiles, that is done on the TilemapRenderer not individually per tile

minor roost
#

of the leaves

#

how then?

slender nymph
#

if you want them to have a different sorting order than the other tiles, then put them on a separate tilemap and change the sorting order for that tilemap

How do I stop an object from animating if it's not shown on the scene

#

Everytime I click this UI button I set the object animates

#

But I want it to animate only when it pop ups

timber tide
#

disable the gameobject it's on until you need it

#

or do you mean it's not reset when you renable it

#

may need to play() again when you activate it

rich adder
#

or put empty state as default starting state

short hazel
#

Animator's Culling options in the Inspector. I think it stops animating when the object is not visible by default

#

Not sure if it works with UI

craggy bane
rich adder
#

no

Just troubleshooting something and just wanted to double check.....

Am I using this correct to assign the parent of an object to another object variable?

GameObject doorToRemove = doorChecker.transform.parent.gameObject;

you just need a way to play your animations though (either transition or call Play)

Hey, I'm trying to scale a UI image by a factor of two but so far setting the size of the gameobject with image.rectTransform.sizeDelta = new Vector2(128f, 128f); hasn't worked and I'm not sure what else would, is there some common way of doing this?

or triggering

yo quick question

if(mouseP.x > 720 && mouseP.x < 780) {
transform.eulerAngles.z = -48.068f;
}

#

i am trying to set the orientation of a sprite

#

dont want to add rotation to it cause when i use transform.rotate it keeps adding up

#

i want to set a orientation

short hazel
#

Those numbers are oddly specific, but anyway

#

transform.rotation = Quaternion.Euler(x, y, z) is how you assign a new rotation with angles in degrees

Hey guys, I have 2 scenes. in the first scene I have the player on the hierarchy always. and in the second scene I want to be able to access that player. how can I do that?

humble lantern
slender nymph
#

why not just multiply/divide its localScale by 2?

humble lantern
#

with something like image.rectTransform.localScale = image.rectTransform.localScale * 2;?

rich adder
#

big brains use *= or /=

#

so we don't write DRY code

humble lantern
#

that works?!

#

i have so much to learn

rich adder
#

yeah so instead of a = a +b
you can just do a+=b

humble lantern
#

ohh I only ever encountered a++ for incrementing

wintry quarry
#

it works sure, it's identical. To avoid floating point precision issues I'd probably do something like this though:

Vector3 originalScale;

void Awake() => originalScale = image.transform.localScale;

void Shrink() {
  image.transform.localScale = originalScale / 2;
}
void Normal() {
  image.transform.localScale = originalScale;
}
void Grow() {
  image.transform.localSale = originalScale * 2;
}
rich adder
#

yea much better than dealing with transform values

Hi ! I have a some problem with my code.

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

public class PlayerInputManager : MonoBehaviour

    PlayerControls playerControls;

        }
        else
        {

        }
        
    }

    private void Start()

        DontDestroyOnLoad(gameObject);

        SceneManager.activeSceneChanged += OnSceneChange;
        
        instance.enabled = false;
    }

    private void OnSceneChange(Scene oldScene, Scene newScene)
    {
        if (newScene.buildIndex == WorldSaveGameManager.instance.GetWorldSceneIndex())
        {
            instance.enabled = true;
        }
        else

            instance.enabled = false;
        }

    private void OnEnable()

#

oh..

wintry quarry
#

not only that but PlayerInputManager is a bad name in the first place because Unity's input system already has such a class, which will be confusing

you cannot subtract arrays

i'm sure its a syntax or spelling error somewhere but i cannot see it

configure your !IDE

eternal falconBOT
steep mist

you are, but you don't mean to

steep mist
#

in what way? is it because zero is typed instead of numerical?

slender nymph
#

no, configure vs code and it will underline the line with the error and maybe you'll see your mistake

steep mist
#

configure it how? i had VS installed for coding class already and it doesnt show me an error

slender nymph
rich adder
#

its as good as a text editor right now

steep mist
rich adder
#

doesn't matter Unity has their own workload

steep mist
#

and many other coding languages so it should be fine

rich adder
#

configuration is laid out in the link, they are very important steps

#

they are particular to unity

rich adder
slender nymph
#

your issue is literally caused by a typo that a properly configured IDE will point out to you

steep mist
rich adder
#

Unity has no native language

#

its just C#

#

but C# configuration for unity is different

#

because unity uses old ass .net

like this ?

neon ivy
#

mostly a question about convention instead of an actual problem.
I have a scriptable object CharacterData and another one called CharacterLibrary to make getting data from specific characters easier.
in CharacterData I have methods GetPortrait() and GetAudioProfile().
would it be smart to give the CharacterLibrary methods GetCharacterPortrait() and GetCharacterAudioProfile to use these get methods from the library?
or should I just do GetCharacter().GetPortrait() in my code?

feel like there's something wrong with this, its attached to an animator that gets the horizontal and vertical axis in wasd movement, and its saving the axis to display the right idle animation too when the character is still, but i feel like its wrong

after you install .net You'd have to try regen project files in Unity again (assuming you did install the update for the VSEditor package) @steep mist

you'll see the option in one of the locations you had to do something when configuring vs code 😉

also this is the correct one right?

yes

at least from visual studio

a different set up to what? vs code? because i was referring to the instructions for vs code

rich adder

but its very picky about it

# fluid kiln amazing also kinda pain T-T

I'd say, do something like this:

public enum Directions
{
  North,
  East,
  South,
  West
}
[SerializeField] private Directions direction
public Directions Direction
{
  get
  {
    return direction;
  }
  set
  {
    if(direction != value)
    {
      direction = value;
      anim.Play(direction.ToString());
    }

well i think then i've done everything, but it still wont debug in vs code

slender nymph
#

you don't need to be using the debugger for this, you just need it configured to see your simple typo

#

but if you cannot get vs code configured, then consider switching to a real IDE that is less likely to be fucked up like visual studio

slender nymph
steep mist
slender nymph
#

go through all of the steps again and you'll see it if you've done it correctly

#

the big button that said Regeenrate Project Files in the preferences step

steep mist
#

by regenerate does that mean open the files associated with the project in vs code

image.png
slender nymph
#

no

#

there is a button that literally says Regenerate Project Files

and i am intentionally not telling you where it is because you've clearly missed steps in the configuration so you need to go through it

So i am thinking of making it so once you click a station character faces that specific stations and shoots out to it. Having hard time with the orientation where it faces selected station. So i was wondering what do you guys think i need to learn to accomplish this, not how but what

so if the object is not jumping then either your force is too low, or something else (like controlling the position via animation) is preventing it from jumping

for some reason the buttons are not working

its interactable, its on the canva, theres nothing on top of the button

#

i really think the Unity is bugged, i already restarted the PC and nothing. Really strange... im getting so pissed off about this lmao

#

why this is happening..

safe carbon
#

is it just transform.right = direction;

#

or transform.right is executed differently

modest dust
#

Also, make a new button, don't change anything and check if that's pressable

#

From there just change one thing after another to see what's the issue

#

Idk if the 4.6 scale doesn't have to do something with this

blissful heart
modest dust
#

It's neither probably since it's not code, lol

#

But as I said, make a fresh new button, which should work out of the box

#

If that's not pressable then there's something blocking it

blissful heart
#

still not clickabl

#

the canva is at 5 layer, how its blocked?

#

blocked from what?

modest dust
#

Something else in the scene, but if there's nothing there then idk

#

Just made a button on layer 5 in my project and it works without any issues

I might be missing something tho since I rarely use the built-in button

can someone see where i went wrong in this code. its supposed to render 6 sides of a cube but its only rendering one side

for some reason its that scene the problem

#

Then probably something in your scene is "blocking" your press

blissful heart
#

good call

modest dust
#

disable one thing after another

or disable everything and bring back one thing after another

that should give you the answer

Hello, I have this sprite, which, as you can see, has a gun that's not in the center of the sprite (along the y axis). I currently have this code to rotate my player towards the mouse cursor, but as you might notice, it rotates the player's y axis towards the mouse, not the gun. I want the gun to point towards the mouse.

        Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        Vector3 direction = mousePos - transform.position + new Vector3(0, 0, 10);
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg - 90;

        transform.rotation = Quaternion.RotateTowards(
            transform.rotation, Quaternion.AngleAxis(angle, Vector3.forward).normalized,                     rotationSpeed * Time.deltaTime
        );

ok the sprite is much tinier than I expected oops >_> Well, he's holding the gun to the right of his head

    public float groundCheckRadius = 0.2f;
    private bool isGrounded;

        // Handle left/right movement
        float moveX = Input.GetAxis("Horizontal");
        player.velocity = new Vector2(moveX * moveSpeed, player.velocity.y);

        // Check isGrounded

This is the inspector with the script stuff

Ground check is not moving with the player

And stays on the ground

#

you should move the rigidbody2d and character_moving from "Captain [Demo]" to captain

#

Thus you can jump infinitely

#

Well, at LEAST move the rigidbody. But far more crucially, move the "Character_Moving" to Captain

#

That is the script actually moving

delete everything and then add an empty gameobject, add your moving script and a rigidbody2d to it
add a square object as a child to it and add a boxcollider2d to it
add another empty gameobject and this should be your groundcheck

just disable it and the isGrounded works properly now.

    private bool isGrounded;

    public int extraJumpsValue = 1;

    private void Start()
    {
        player = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        // Handle left/right movement
        float moveX = Input.GetAxis("Horizontal");
        player.velocity = new Vector2(moveX * moveSpeed, player.velocity.y);

        // Check isGrounded
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, groundLayer);
        Debug.Log(isGrounded);

        if(isGrounded) extraJumps = extraJumpsValue;

        //Handle Jumping
        if (Input.GetKeyDown(KeyCode.Space) && (isGrounded == true || extraJumps > 0))
        {
            player.velocity = new Vector2(player.velocity.x, jumpForce);
            if (isGrounded == false) extraJumps--;
        }
    }

you need to reset the extraJumps when ever you get back on the ground

hey guys how can I save the color of an object when I am saving data using a method like that ```cs
public static void SavePlayer(Player player){

    string path = Application.persistentDataPath + "/player.save";
    PlayerData playerData = new PlayerData(player);
    var savePlayerData = JsonUtility.ToJson(playerData);
    File.WriteAllText(path, savePlayerData);

}```

I need some advice regarding my code. Basically I have a text file that had like 4 million words in it I wrote along the years, but that's besides the point. I have a button that displays a random chunk of it, but it sometimes freezes the game or crashes it the first time you press it but not consecutive times. I have the text preloaded, or had it but the problem persisted. (I didn't remove the preloading thingy) I haven't tested it yet but I added a new line of code: chunkSize and set it to 1000 (lines) or something like that.

Will this fix my problem or should I split the text in multiple files?

solemn fractal
# rich adder same way you save PlayerData

my player data now: ```cs
[System.Serializable]
public class PlayerData{

public int coins;
public int movementSpeedSkillLevel;
public int movemenSpeedSkillValue;
public float playerSpeed;

public PlayerData(Player player){
    coins = player.coins;
    movementSpeedSkillLevel = player.movementSpeedSkillLevel;
    movemenSpeedSkillValue = player.movemenSpeedSkillValue;
    playerSpeed = player.PlayerSpeedControl();  
}

}``` its working fine.. but here I would need to fetch information from a specific component in a specific object to fetch the color. I will be able to do that here?

rich adder
#

You technically won't have the same exact object

#

just use the values to the object from this file

solemn fractal
rich adder
#

wdym Gameobject don't have color no?

#

also GameObject is very much not needed, use directly whatever script these objects are

eternal needle
rich adder
#

all my objects that load stuff have an an interface of ILoadData , I have an event that calls all the LoadData types

because its not inheritance you can add many interfaces on 1 script

Yes. But I don't think that's the main issue. I'll try looking in the profiler like bawsi said.

GetRayIntersection is weird

#

is therea a reason ur not using RaycastHit2D

rich adder
#

use EventSystem raycast

woven crater
#

is EventSystem raycast use specificly for ui?

rich adder
#

yeah its literally meant for it

woven crater
#

"insert the more you know meme"

#

thank ya

rich adder
#

you can also just use IPointer interface

woven crater

whats that?

is a scene that is additively loaded running on a different thread from the first scene?

JOBS 🙂

eager spindle
#

jobs D:

#

i thought i could at least run a scene additively on a different thread so that my loading screen doesnt hang

rich adder
#

just use LoadAsync version

rocky canyon
#

i use a little timer at the end with a black fader

eager spindle
#

i need the scene to run on a different thread all the time because when I load my main scene it runs an expensive operation

#

i should probably optimise my code

rich adder
#

async could potentially be sufficient ofc you can always move it to a multi-thread operation if you must

summer stump
eager spindle
#

the process involves instantiating objects which jobs doesnt like

#

but come to think of it i should not instantiate 100,000 game objects

rich adder

time to convert to ECS

Ecs or fake a lot of the objects by directly drawing them in the gpu. Do they NEED to be gameobjects?

eager spindle
#

not really I can convert my code to use structs

#

drawing them directly in the gpu should be fine I just need to get tmpro's meshes to work with me

#

if I use the default cube mesh provided by unity is it supported by gpu instancing?

#

oh it does

abstract finch
#

Ive tried many things so I'll ask here, I need to check if a target is facing another. Not if a target is looking at the other objects front. I simply need to check if its at a minimum angle to trigger an attack.

verbal dome
#

What have you tried?

abstract finch
verbal dome
#

Looks correct.

abstract finch
# 
            
            float dotProd = Vector3.Dot(dirFromAtoB, transform.forward);```
#

Its getting wierd values ill try to debug and show it

verbal dome
#

That also looks correct

abstract finch
#

Then it goes to 40 for some reason

#

the 40 is when the navmesh agent stops rotating meaning its looking at the target so it no longer needs to rotate

#

the number should be decreasing to 0 right

verbal dome
#

It won't decrease to 0 if you tell it to stop rotating at angle 40

abstract finch
#

right but the way the value is going is odd, the navmesh agent over time rotates toward the target

#

this is 60

image.png
#

the last pic (40) is when it officially is fascing the target

verbal dome
#

Don't expect me to know what's going on here. Like who's the transform and who's the target

abstract finch
#

ah the left is the transform and the capsule is the target

#

the cube in the front of the left transform represents the head

#

the rotation is done by navmeshagent by default it rotates towards its destination, in this case the target transform

verbal dome
#

Maybe you want to check the Y angle only?

#

float angle = Mathf.Abs(Vector3.SignedAngle((target.position - transform.position), transform.forward, Vector3.up));

abstract finch
#

yea

#

giving that a shot thanks

#

still the same problem

#

im going to try this in another scene and manually rotate it myself

verbal dome
#

So the problem is that it says 40 angle when it is directly facing towards it (and angle should be ~0)?

#

@abstract finch Try drawing the two directions to debug it

abstract finch
verbal dome
#

There is a reason, you just haven't debugged it to find out

#

Draw the two directions that you pass into angle/signedangle

abstract finch
#

how would I do that?

#

you mean debug to get the values of the signed angle and transform forward?

verbal dome
#

Debug.DrawLine/DrawRay, for example

abstract finch
#

the code works fine in the test scene when i rotate the object myself

#

ok i found out the issue its because the enemy transform is a lower Y level then the target

#

so what I will do is create a new Vector3 with the same y as the target and it should work

verbal dome
verbal dome
abstract finch
# 
            signedV3.y = 0;
            float angle = Mathf.Abs(Vector3.SignedAngle(signedV3, transform.forward, Vector3.up));
            Debug.Log(angle);```
verbal dome
abstract finch
#

is the one you provided more versatile?

#

because I plan to have flying enemies as well

eternal needle
abstract finch
#

got it thanks

verbal dome
#

The whole point was to not consider height. If you still want height to affect the angle, you might want to adjust the origins used for the direction (target.position - transform.position)

#

If it's a visibility check or something like that, you can ignore the height when the distance is below a certain threshold

cerulean crypt
#

Is there a quick way of getting an instance of the GameObject a Script is attached to? Currently I'm using a [SerializeField] attribute and then setting it to itself, which seems unnecessary

verbal dome
#

It is a MonoBehaviour property and will always exist because MB's always live on a game object

cerulean crypt
#

Also, follow up

#

Is there any way to like, disable an empty (so the child objects go invis) without preventing event functions from being called?

#

So like, RN, I've grouped some buttons using an empty. They know when to disappear because they have a listener method. However, that listener method gets disabled along with the whole script annoyingly. Is there any way around this?

#

Oh, like disabling the child objects ig...

#

Yup, that works. Cool, thanks for reading my ramblings 😂

topaz mortar
#

lol, how do I set this?
Equipment equipment = FindFirstObjectByType(FindObjectsInactive findObjectsInactive) <Equipment>();

#

I need it to return an inactive object too

eternal needle
topaz mortar
#

yeah I found another way to get equipment 🙂

eternal needle
#

that code looks very off too, why is there 2 sets of ()

#

it should be FunctionName<Type>(params);

verbal dome
#

To answer your question, it would be FindFirstObjectByType<Equipment>(FindObjectsInactive.Include)
But yeah, avoid Find

topaz mortar
#

yeah ik

#

I should really learn how to use singletons

#

but there's so many different ways to implement them

#

does C# have something in between discard (_ = await ...) and await?
I'd like my code to keep running, but I do want to make sure my Task is eventually finished

teal viper
#

Why would you need to discard it then..?

eternal needle
# topaz mortar but there's so many different ways to implement them

there really isnt, you may see different ways online but most of them might be an all encompassing overkill solution or may be related to other fields of work. Some use the Find functions to ensure there is only 1 (and throw an error if theres more), but you can just Debug.LogError in the if statement of my example below. You really dont even need thread safety, because i think async/threading stuff isnt needed in most cases. I dont know any cases where you would want to use it tbh
Simplest way can just be

public class SomeClass : MonoBehaviour
{
    static SomeClass instance;
    public static SomeClass Instance => instance;

    void Awake()
    {
        if (instance != null)
        {
            Destroy(gameObject);
            return;
        }
        instance = this;
    }
}
#

there is also a way to write it with generic classes, but its more so you dont write repeated code instead of actually needing a base class.

topaz mortar
#

cool thx

#

time to refactor my entire code lol 🙂

ivory bobcat
#

What're you refactoring?

topaz mortar
#

making my character a singleton

ivory bobcat
#

Should there only be one?

topaz mortar
#

yup

#

been wanting to do that for a while, but it just seemed too complicated

ivory bobcat
#

Ensuring that ease of access isn't the sole reason to doing so

topaz mortar
#

there's only one, it's in the scene and never destroyed/created

#

and I need to access it everywhere

teal viper
#

Making the player a singleton doesn't sound like a great idea regardless of the circumstances. Maybe make it a property of a singleton game manager.

topaz mortar
#

should be totally fine for my concept, it's not a game where you run around and do stuff

ivory bobcat
#

Usually the purpose of a Singleton is to prohibit the use of multiple instances of the object. They make good patterns for managers that observe other data. They're not a good pattern for use with objects that actually may need multiple instances - quite annoying to undo all of the constraints and dependencies of the ease-of-access instance field/property.

#

And changing the Singleton can have annoying after affects upon other classes

eternal needle
#

Something is going to have to spawn your player, so whatever spawns it can pass it to a singleton game manager easily. If your player already exists in scene, its simple, drag it in the inspector to the game manager

topaz mortar
eternal needle
# topaz mortar but here you told me to just use a singleton?

and the game manager being a singleton is still relevant, you havent really described what this is for so I cant recommend the entire best practices based off 1 line of code. I did find it weird that this was being done on a script called Equipment initially, but i cant really assume what its for

topaz mortar
#

so I should have a gamemanager that is a singleton
to hold a reference to classes like character (which has equipment) to make it easily accessible?

eternal needle
#

a game manager makes more sense to be a singleton, because you wouldnt want multiple instances fighting over stuff. I cant really suggest much because i dont know what needs access to the player

woven crater

so i put my item gameobject in the event trigger. the item is a physical object in the scene right now . can i still be able put an instance of the item game object in here in the future??

topaz mortar
woven crater
#

well for testing right now the item game object is in the scene im gonna start to instantiate the this item game object in the future, my question if i can still be able to use the event trigger component?

topaz mortar
#

if you make it a prefab and instantiate the prefab then the new gameobject should have the triggers too yes

woven crater
#

you mean i can just put the prefab in the event trigger component and it will work for the instance of the prefab?

#

ah thank you

topaz mortar
#

eh no

#

well depends, it might work in your usecase
don't really know what ur trying to do

teal viper
#

An event assigned in the inspector would always invoke with the parameter you set in inspector.

Hi, does anyone know why i can't access a bool variable from another object?

image.png image.png image.png
#

I initialized it in 2 objects but i can access only from an object which has the same prefab

#

it needs to be public, but i can't understand why its working without public in planescript

static cedar
#

Ah.

#

public means it can be accessed anywhere.
If you just leave it blank int some_class_var; it's implicitly private.

#

And when it's private, only the type itself can access it.

#

I'd prefer if you take a screenshot of the error code too.

ruby python

I watched a GDC vid that was about an alternative way in handling quests where a quest is described in multiple states of statemachines in the game, the example given was the state of a commoner if they asked you to kill a wolf, getting impatient and being gone (going to solve it themselves) and the state of a wolf in the woods, if you've heard of it, if you've seen it and if you've killed it.

I'm thinking of a dynamic way of implementing this where the player has a list of states with an ID as to what state machine it belongs to and characters, monsters, places, etc. have those state machines and add to the list as soon as the player has exited the null state. I'm not sure how to implement this though.
I thought of using a list of enums for the state machine but that's not dynamic at all. what is the best way to handle this?

ruby python
#

Mornin' all, I'm having a really weird issue that I can't figure out and it's bugging me. lol.

I'm cycling through a list of objects and for each object I need to find/assign it's parent.
But I keep getting the good old 'Object reference not set' error and I can't figure out why it's not finding the parent of my object.

The debug reports correctly, but it craps out when doing the assigning (ie, doesn't know what 'doorChecker.transform.parent.gameObject' is

    Debug.Log("Number of Door Checkers = " + doorCheckers.Length);
    foreach (GameObject doorChecker in doorCheckers)
    {
    GameObject doorRootObject = doorChecker.transform.parent.gameObject;

Highlighted object in the hierarchy is what is assigned to 'doorChecker'

image.png
static cedar
#

You mean doorChecker.transform.parent.gameObject is null or the property somehow doesn't exists according to the compiler?

static cedar
neon ivy
#

a what now? xD

languid spire
#

or you have null entries in the array

static cedar
# neon ivy a what now? xD

It relies on something called abstraction.

public abstract class BaseState 
{
  public abstract void MethodToUpdate();
}

public class StateOne : BaseState
{
  public override void MethodToUpdate() { }
}

public class StateTwo : BaseState
{
  public override void MethodToUpdate() { }
}

These types can be considered BaseState and when you try to call their MethodToUpdate it depends on the actual type of the object.
If the value is a StateOne, it calls the MethodToUpdate from that. And so on.

public sealed class StateManager
{
  private BaseState base_state;

  public void CallTheUpdate() => base_state.MethodToUpdate();

  public void ChangeState(BaseState new_state)
  {
    base_state = new_state;
  }
}

And then you would traditionally have some state manager that all states need to hold, just put it in the constructor of the BaseState so all classes that inherit it(see the : part then the BaseState, the type will hold everything the BaseState has) will automatically have it.

This way, each state object represents a state of it. Better than chaining tons of if or switch cases.

#

If you still can't understand this, i'd suggest you to watch a video about polymorphism or abstract.

static cedar
ruby python
#

This is so weird. I removed that line temporarily and added debugs/object renaming....

foreach (GameObject doorChecker in doorCheckers)
{
 Debug.Log("I am a door checker");
 doorChecker.name = "ThisIsWhoseParentImTryingToFindAndMyParentIs";

This works fine, but as soon as I add the line to find the objects parent, it craps out (even adding it to the end of the rename (hence the 'And my parent is).

why do you not just debug the data, then you would know. what you have done is pointless because you know no more now than you did
