Ah, should have said that. I thought when you said state, you'd want different behaviours in each state (Player Run, Player Jump something).
In that case, doing what I said might be detrimental.

ruby python
#

Yeah I did the check. and it didn't output anything. I also tried it with .gameObject at the end of the check and it crapped out again. So I'm confused as to how it found the parent Transform but not the parent GameObject.

neon ivy
#

you can make custom operators?

#

I'm more familiar with classes than structs so I think I'll try that

ruby python
#

Oh, sorry no, the null check didn't log anything because it found the parent of all the doorChecker objects I'm cycling through. So there was nothing null.

The other stuff that I put in worked fine (log and test renaming the object).

static cedar
#

In Update for example.

neon ivy
#

does it cause lag?

static cedar
# neon ivy you can make custom operators? 
    public static bool operator ==(ScreenVector former, ScreenVector latter)
    {
        return former.x == latter.x && former.y == latter.y;
    }

Welp, once you made your own == operator though, compiler might wine a bit.
So you need to add these as well.

    public static bool operator !=(ScreenVector former, ScreenVector latter)
    {
        return !(former == latter);
    }

    public override int GetHashCode() => HashCode.Combine(x, y);

    public override bool Equals(object? obj)
    {
        if (obj is not ScreenVector screen_vector) return false;

        return this == screen_vector;
    }

# neon ivy does it cause lag?

No, but it can crash (i think) if you went nuts since it will eat RAM. So i guess it will still lag lol. The more fields a class have, the bigger the weight or memory.

Because it has no parent

#

No other possible cases

#

a.transform.parent can be, and will be null when a has no parent

neon ivy
ruby python
#

Sorry, I'm just trying to understand. If it can find the parent Transform, which is a component of the parent GameObject, why does it crap out when looking for the parent GameObject but not the Transform? That's what is confusing me.

static cedar
short hazel
# minor roost ? so how

From the Inspector. Rotate it back to what it was originally (Z rotation to 0) and change the game view's aspect ratio from the "resolution" dropdown at the top-left

short hazel
#

So they don't all have a parent

minor roost
#

#

nvm

minor roost
#

cant find it

image.png
ruby python
#

I just added .gameObject to the 'null' check and it threw an exception. Which is even more confusing, because if it's null it should just log the error.

languid spire
#

no

short hazel
#

No!

#

It's .parent that is null!

#

Hierarchy is made with the Transform, so that one holds parent-children information

If i have to put it in another way, instance of classes hang around. And someone needs to clean up the mess but still sticks a while.
If we're finished using structs, we would throw them away immediately. But with classes, it's like we leave them around the counter for a while until your mother asks you or your brother if someone uses it and then your mother realises, she have to throw it away cause no one needs it anymore. (There's no more classes that references it)

ruby python
#

Okay, still a bit confused about it tbh lol, but it's working now. Thank you for the help guys.

languid spire
ruby python
#

I'm trying. lol.

static cedar
#

When asking about why something doesn't work. Please mention if there's a red warning sign right in the console first and foremost. UnityChanwow

#

Also what's the name of the Exception, and the line it occured. UnityChanThink

short hazel
# ruby python I'm trying. lol.

Question for you. Given this code: someObject.transform.parent.name, which gets the name of the parent object in someObject - In the Hierarchy, the object in someObject has no parent. Which one of these will be null, to signal there's no parent?

  1. someObject
  2. .transform
  3. .parent
  4. .name
    One possible answer only
ruby python
#

lol. Wouldn't let me just put the answer. But 3.

short hazel
#

Correct

ruby python
#

I do understand that part. The thing that's confusing me is being able to find the transform, but not finding the transforms GameObject, if that makes sense?

short hazel
#

Find what Transform, the someObject.transform?

#

Or the .parent?

static cedar
#

The problem you had was that the parent is null. And you're trying to access the gameObject of a non-existant value from: parent.

ruby python
#

someObject.transform.parent - is found.
someObject.transform.parent.gameObject - is not found.

It's the difference between finding the two that's the confusing part.

short hazel
#

The first one - it's not found, because it's null

static cedar
#

parent wouldn't throw a NullReferenceException because it did it's job. It's giving you null or a reference to a transform object.

short hazel
#

Transform:parent returns null if the Transform has no parent, it's in the docs

static cedar
#

It only throws NullReferenceException when you try to get through something that doesn't exist.
That means that getting null by itself, isn't a problem, the problem is what you might do with it, which is where the exception is getting thrown. :0

short hazel
# 
string str = null;
Debug.Log(str.Length); // NullReferenceException! 'str' is null, can't access its 'Length' variable
ruby python
#

Sorry, I really don't mean to sound really stupid, just honestly trying to understand the 'why' of it.

If the code can find the parent transform, which lives on the parent GameObject, why can it not find the parent GameObject?

I don't understand how the GameObject can be null if the Transform isn't. Does that make sense at all?

short hazel
#

It cannot find the parent transform, and it tells you that by giving you null

ruby python
#

But it can. It works fine finding the parent Transform, but not when I try to find the parent GameObject.

short hazel
#

What do you mean exactly by "find" here? Like being able to type it in the code?

#

It's vastly different than what can happen when the same code runs

ruby python
# 
foreach (GameObject doorChecker in doorCheckers)
{
  Debug.Log("I am a door checker");
  if (doorChecker.transform.parent == null)
    Debug.Log(doorChecker.name + " has no parent");
  Transform doorRootObject = doorChecker.transform.parent;

Works fine, finds the parent Transform.

foreach (GameObject doorChecker in doorCheckers)
{
  Debug.Log("I am a door checker");
  if (doorChecker.transform.parent.gameObject == null)
    Debug.Log(doorChecker.name + " has no parent");
  GameObject doorRootObject = doorChecker.transform.parent.gameObject;

Throws an exception, can't find the parent GameObject.

This is the part I'm struggling to wrap my head around.

short hazel
#

It does not find the parent in the first block of code

#

doorRootObject will be null

ruby python
#

Well, it does. 😕

short hazel
#

No, it doesn't

nimble apex
#

if transform.parent is null , it is null, it gives an exception error because u said transform.parent**.gameobject**

short hazel
#

It does not throw an exception because because you're not doing anything with doorRootObject just yet

#

Try to access anything on that and you'll get the NullReferenceException

nimble apex
#

u used the null value

Heey, hi everyone... Could someone help me with this? ```cs
using System.Collections;
using System.Collections.Generic;
using System.Runtime.CompilerServices;
using UnityEngine;

public class LoadingScreen : MonoBehaviour
{
private float loadingCanvasTime = 2.2f;

[Header("Drag")]
[SerializeField] private GameObject loadingCanvas;
[SerializeField] private Animator loadingCanvasAnimator;
[SerializeField] private Animator loadingTextAnimator;

void Start()
{
    StartCoroutine(CanvasTextFade());
}

private float time;
private IEnumerator CanvasTextFade()
{
    loadingTextAnimator.SetTrigger("ActiveLoadingFadeText");

    yield return new WaitForSeconds(loadingCanvasTime);       
    loadingCanvasAnimator.SetTrigger("ActiveLoadingCanvasFade");

    yield return new WaitForSeconds(0.3f);
    loadingCanvas.SetActive(false);
}

}```This code is responsible for controlling the initial loading screen of my game. As you can see, it takes 2.2 seconds to disappear from the start of the game. For this reason, I would like to create a function, similar to Start or Awake, that can be accessed from anywhere in the code within the project. When calling this function, I want it to execute 1.1 seconds after the loading screen starts. The purpose of this is to free up Awake and Start to achieve a smoother and more dynamic start. Maybe it’s silly… but I have the feeling that it looks less fluid when I call too many functions in Awake or Start.

static cedar
#

Let me put it like this, transform.parent gave you the answer I didn't found anything which is equivalent to null.
There's nothing stopping it from giving you that answer because it's completely valid.
You can do stuff like.

if (transform.parent == null)

Then deal with yourself.

Or if you try to use it anyways, the runtime will get mad like what happened with transform.parent.gameObject. You asked for the transform and it gave you its transform. And then you asked for its parent, it answered with null, it didn't have a parent. And then you tried to get gameObject with it, but the parent beforehand answered with null and it's having problems with that.

gameObject here isn't null, the parent is.

nimble apex
#

class.functionA.functionB.parameterA

if functionA is null

functionA.functionB will return an exception

#

because u used functionA to execute functionB

short hazel
#

The console will hold the essential information here

#

Look for "<some name> has no parent" messages

static cedar
#

Does null reference converts to "null"?

short hazel
#

Empty string, IIRC when concatenating

static cedar
#

Ah.

#

I never tried it, i always assumed that it does ToString() in the method and would just throw a null reference error.

short hazel
#

There is at least one more "DoorLocked (clone)" object that has been cropped out of the screenshot below

static cedar
#

And i always do object?.ToString() ?? "null" anyways.

short hazel
#

Yeah same, can be shortened down to obj ?? "null" in most cases. But watch out as ?. and ?? don't work properly with Unity objects (it bypasses their destroyed-but-not-null-yet state)

ruby python
short hazel
#

Try a more explicit version so it doesn't get drowned out by the other logs

ruby python
#

That's the entire console

short hazel
#

Use Debug.LogWarning() for example

ruby python
#

No 'no parent' entries in there.

short hazel
#

Put this before the foreach loop

foreach (var obj in doorCheckers)
{
    if (obj == null)
        Debug.LogError("There is a null object in the list!");
    else if (obj.transform.parent == null)
        Debug.LogWarning($"Object {obj.name} has no parent!", obj);
    else
        Debug.Log($"Object '{obj.name}' passed all checks, its parent's name is {obj.transform.parent.gameObject.name}");
}

I'm starting to think the code you're showing isn't the one that's executing

#

This will, for each object in the list, ensure they're "valid"

static cedar
#

$"Object '{obj.name}' passed all checks, it's parent's name is {obj.transform.parent.gameObject.name}"

#

Might as well add that extra bit in the sentence.

short hazel
#

Good point, edited

static cedar
#

It really does get converted to "". :p

image.png
short hazel
#

Nothing beats creating a whole solution to check. Also longest cast I've seen lol, 19 seconds

static cedar
#

I doubt it's the cast, it's the method.

ruby python
#

Everything came back as 'passed all checks' 😕

I seriously appreciate the help, even though I don't fully understand the why, I know the how, so for the moment that's good enough tbh. Really don't want to waste any more of your guys time. It works, so for now that's good enough.

static cedar
#

I was thinking if you tested it right after you fixed the bug lol.

#

That kinda just confirms it. :p

ruby python
#

Really do appreciate you guys taking the time, thank you.

short hazel
#

The second part of the sentence asks you a question, you did that on purpose didn't you
Note that dividing a vector by zero will produce an infinite vector, so check if you have any divisions in your code

Guys, I have a problem with my movement.
I can jump while my character is on the left side of the map as you see in the video, but there's an invisible wall on the right of the camera which makes my character's movement heavily limited. I can't even jump to the second platform on the right.

fix your pivot point first, if you add any objects dont put them on the root put them as child

#

set this to pivot

Screen_Shot_2023-12-03_at_10.13.47_AM.png
#

that fall detector is probably useless but move it to child object for now

verbal dome
#

I thought it already does that? Like tilting left/right when steering

#

WheelCollider.GetWorldPose gives you the orientation of the wheels

#

You can modify the quaternion it returns before applying it to your wheel visuals

prime horizon

#

why you did not do any of the stuff I suggested?

#

I never understood that, i said a specific thing and you did your own thing lol

I just remake it, I put the charater sprite as root, the falldetector and the groundCheck as children and I set the option you showed me from Center to Pivot.
What did I miss?

#

Oh nvm

I just realized.

#

That fallDetector is not "is Trigger"

#

So that box is the thing holding my jump height

#

or maybe my script is wrong too. The box is supposed to stay there and can only move left or right with the player.

summer stump
#

GroundCheck being false means you are not on the ground. Which means you are jumping or falling

rich adder
#

yes why even have that thing

summer stump
#

If you want, you can check if the y component of velocity is negative to see if you're falling

if groundcheck == false && velocity.y < 0

prime horizon
#

I need that thing for the respawn. If I fall, my character hits the box and it will respawn.

not good way to do it

Hey, guys! In order to manage in my options scene with sliders my main menu music and main game music and sound effects separately do i have to use audio mixer?

should

sage mirage

So, I will probably have master volume, main menu volume music, game volume music and sound effects volume something like that? I mean for groups in my audio mixer

@rich adder Hey! But if I want to control my menu music and main game music with just a one slider then I will need only master, music and sfx groups with it's exposed parameters right?

#

I mean for main and menu music one slider and for sound effects another slider

some separate it

What is better to separate them or not?

#

Why not separate sliders and a master slider?

sage mirage
#

You mean slider for menu, slider for main game and master slider?

summer stump
#

What osmal said is the norm. Thay is what almost all games do
I thought that's what you meant too stelios haha
Of course have a master slider.
But also break it up

verbal dome
#

Yes, well that's what I was talking about, so did you try GetWorldPose?

sage mirage
#

Master is a group that is in default in audio mixer btw

verbal dome
#

With master I mean a slider that controls all the music mixer tracks, not necessarily the master track

#

Or channel, whatever they are called

#

(I don't really use Unity builtin audio - FMOD ftw)

tilting wheels xD defines physics

You can do something like wheel.Rotate(0, 0, steerAngle) after using GetWorldPose

do they? thought they only shift up and down

suspensions and alike

ohhhh like side to side tilt yeah more common in 2 wheeler

#

idk why i thought front to back xD

verbal dome
#

Ok and I have told you how to do this

#

What is confusing you?

#

You should have separate objects that just hold the MeshRenderer of the wheel

#

Rotate those, don't touch the object that has the wheel collider

#

Why?

#

Looks like that's not possible, the wheel collider aligns to the parent rigidbody

change it to anything you like, player will never jump

GetKeyDown is 1 frame process

no, KeyDown only fires once

exactly, which is 0

which is what is fed into FixedUpdate

so getkey would work

not really. You should use KeyDown to set the vertMovement and KeyUp to reset it

so far ive copied the script from the description, made an empty object, put the mesh renderer in, assigned the default material, put the mesh filter in, then the script. nothing really happens after

verbal dome

#

yeah, messed with the values while play was pressed too

#

for context im trying to make an educational thing for my college thesis around vector math and stuff so i need to visualize the vectors

need a way to be able to render arrows based on rng'd values

#

oh i guess more context im working in unity 2d

verbal dome

#

oh, how should it look like?

verbal dome
#

It should be in front of the camera

i have it under canvas, would that work?

Object at (0, 0, 0)
Camera at (0, 0, -10)
Object is visible

Canvas is for UI

gotcha

hmm yeah camera is at default and this is the object

verbal dome
#

Create the object from scratch. It shouldn't have a RectTransform

#

RectTransform is for UI, it got changed when you put it in a canvas

verbal dome
#

Also not sure if that shader/material is going to show

slender depot
#

works now thanks man

#

doesnt show up before pressing play, is that normal?

verbal dome
slender depot
#

ok new problem

#

seems to render under my background, should it be placed after?

hmm even placing it after it still renders under

verbal dome
#

What is your background made of?

#

Like what components

slender depot
#

here you go

verbal dome
#

It's UI so it's rendered on top of everything else. Would make more sense to use a world object like you do with your arrow

I have this interface:

public interface IEncounterable
{
    public static event Action<string/*encounterID*/, string/*encounterStateID*/> OnEncounterActivated;

    public void ActivateEncounter(string encounterID, string encounterStateID)
    {
        OnEncounterActivated?.Invoke(encounterID,encounterStateID);
    }
}

and I want to call ActivateEncounter() in this way:

  case ENCOUNTER_TAG:
                    string[] splitId = tagValue.Split(",");
                    if (splitId.Length == 2)
                    {
                        ActivateEncounter(splitId[0], splitId[1]);
                    }
                    break;

the script this code is in has IEncounterable but doesn't see ActivateEncounter() as a method.
am I missunderstanding interfaces?

Hey everyone! Can you guys suggest a beginner unity tutorial? I've used to have experience with unity but it was 2015 or so hence most of the stuff I remember is irrelevant or outdated. I know basic C# and overall programming and my goal to make simple small games, mostly low-fi 2D. There's just too many videos and it's really hard to choose a single one from this whole plethora of content.
My requirements are basically:

  1. Something simple, I'm not going to use net code, advanced graphics or make complicated systems so I need something that's easy to follow and doesn't use redundant features.
  2. A preferably a series of videos, I think it's almost impossible to teach all important stuff in one video.

I think I just don't understand how to use an interface xD

rich adder
#

interfaces aren't inherited 😦

#

don't wanna get all pedantic but diff between implementing and inheriting
when you "inherit" you are always restricted/limited to your. base class at the end of the day and you're only part of that "hierarchy"
Implementing is more modular and Many things can have something in common without being connected otherwise

summer stump
# neon ivy I think I just don't understand how to use an interface xD

Think of an interface as a remote control. The class human calls a method called change channel on the class television. Human doesn't need to know how the television implements that method. And tv can change how it implements it (like when they went analogue to digital) and still just show the "change channel" method. So nothing changes for Human

modest dust
#

Interfaces are more of a contract where you do a pinky promise that you'll implement the fields and methods of the interface into your class. So if you don't implement it then you won't be able to use it within the same class. Other classes can call these methods as they truly believe that you did what you had to do and implemented these methods as you should

#

I believe you can do "default implementations" but these will be just seen as virtual and you can override them and then use them

Guys, does anyone know how I can change the material of my model? This code does not work for me but in reality it does because in the debugs it is shown that it is fine but it does not change the material and I also want that if the material is the same as the material that I want to change, the code is not executed (eg: change color black the weapon but it already has black color so it does not execute) ``` Material m;
public Material m1;
public Material m2;
public Material m3;
//SkinnedMeshRenderer r;
// Start is called before the first frame update
void Start()
{
m = gameObject.GetComponent<SkinnedMeshRenderer>().material;
//m.enabled = true;
//m.sharedMaterial = m;
}

// Update is called once per frame
void Update()
{
    if (Input.GetKeyDown(KeyCode.F) && m != m1)
    {
        m = m1;
        Debug.Log("F pressed");
    }
    if (Input.GetKeyDown(KeyCode.G) && m != m2)
    {
        m = m2;
        Debug.Log("G pressed");

i see the log

#

the SetVolume function gets called

#

#

but this line isnt doing anything

short hazel
#

Audio mixer volume operates on a logarithmic range, setting a value that is between 0 and 1 won't do much

near cove
rich adder
#

ah yes

#

you need to do Log10()

#

iirc

near cargo

#

Log10(vol) * 20 IIRC

near cargo
#

but why it works when i run the game in the editor

gaunt ice
neon ivy
rich adder
near cargo
#

yes, and the volume changes accordingly

#

except in the actual build the volume doesnt change at all

#

so i change the slider's min max to 0 and 1 respectively and Log10(vol) * 20?

rich adder
#

so the value from the slider

modest dust
rich adder
modest dust
#

You need to add public static event Action<string/*encounterID*/, string/*encounterStateID*/> OnEncounterActivated; into your class and use that, not InterfaceType.Event

near cargo

ill try log10(vol)*20

neon ivy
#

I'm just trying to force an interface into this while it really has no place being there

near cargo
#

yeah no change

modest dust
# neon ivy at that point I should just use a singleton to handle this event instead of impl...

Well, you need to understand that an interface is not an extra class slot to have extra inheritance. It's a contract to implement your own, custom behaviour for the methods and properties listed in the interface (so that two classes can both have, for example, a PrintDetails() method, both are called in the same way, but one prints details of how a car is made and the other prints details of a shopping transaction)

#

If a singleton is what will help, then go with it

neon ivy
#

all I wanted was to call an event from any script that has the relevant data

#

for some reason I thought interfaces were the way to go for that. but it's not

The list is empty. You need to .Add() elements into it. Can't access them with [i] to add a new element

why isnt this line of code making my character move? removing deltatime fixes it

rb.AddForce(movement * (moveSpeed * Time.deltaTime));

short hazel
#

Deltatime decreases the force by a factor of 100

#

The force is still there, it's just not noticeable

stuck palm
#

oh damn

#

setting the speed to like 1000 instead of 10 fixes it

short hazel
#

At a stable 60 FPS, delta time is 1 / 60 or 0.016

#

The time in seconds since the last frame

#

Using deltatime for applying forces is not recommended anyway. AddForce already smoothes out the force over a few frames

summer stump
#

When you need massive numbers like that, it is a sign you are doing things wrong/fighting the engine

stuck palm
summer stump
#

AddForce modifies velocity, which is in meters per second.

#

You do NOT want deltaTime in addforce at all

stuck palm
#

you can see a clear increase in speed when i focus on the gfame window

AddForce is not dependent on frame rate

so why is the speed increasing then?

You should also not use deltaTime in slerp haha. At least not multiplying it. Sorry

rich adder
#

iirc you still need it in the speed calc for inputs

stuck palm
#

i thought you had to use deltatime to make things more consistent across framerates

rich adder
#

like horizontalInput*moveSpeed* Time.deltaTime

#

i think

short hazel
#

That's why physics go into FixedUpdate, which by its name, runs at a fixed rate

rich adder
#

oh wait yeah also its in update nvm what i said

stuck palm
rich adder
#

rigidbodies movements go In FixedUpdate

rich adder
short hazel
#

It's more of a convention, poll input in Update, and deal with the Rigidbody in FixedUpdate

summer stump
short hazel
#

I'd also change the code that deals with the rotation to use rb.rotation, so it's consistent with the position changes you apply with AddForce. You'll experience less jitter as both will we applied at the same rate

As the mesh collider is not a trigger collider, OnTriggerEnter will not be called for that one. So you can be 100% sure that when this method runs, it will be because of the box collider

it's not picking the points very randomly, it's locking onto the player position

wait i didn't accnt for null so it skips that? idk lemme see

       Ray ray = Camera.main.ScreenPointToRay(mouseP);
       RaycastHit2D hit = Physics2D.Raycast(ray.origin, ray.direction);



       if (hit.collider.name != null) {

           //transform.rotation = Quaternion.Euler(0,0, - 48.068f);
           //transform.rotation = Quaternion.EulerAngles(0f, 0f, 80.976f);

I'm trying to use the unity VCS to work on my project on two different computers. When I add the project as a remote project on the second computer there are some issues - I can mostly see the project as it was on the first computer, but any values I have set in the inspector (for serializedfield variables) are no longer defined.

Do I need to do something specific to check in changes made in the inspector? One computer is a PC and the other is a Mac if this is relevant.

smort

#

omg

slender nymph
#

and it's because you are checking the name property on a null collider

safe carbon
#

but i added box collider

#

to the object

slender nymph
#

sure, but what if your raycast doesn't hit anything

safe carbon
#

ic

#

what is the solution

slender nymph
#

check that something was actually hit by the raycast. RaycastHit2D has an implicit cast to bool that just checks if the collider is null so you can do that or you can check if the collider is null

safe carbon
#

alright thx

is it possible to grab a gameobject which access a certain method on a script?

#

lets say i have this RemoveHealth function

image.png
#

when i call this from another script i need to grab the game object which accessed it

slender nymph
#

pass the object as a parameter to the method

tender stag
#

yeah i was thinking of that

#

but im just wondering if theres a way to do it automatically

cosmic dagger
slender nymph
tender stag
slender nymph
#

and?

tender stag
#

and i need to know which object, this object took damage from

slender nymph
#

yeah so you'll need to pass that to the method then

#

but i also don't see why you need the game object

tender stag
#

im making a damage indicator

#

and i need to rotate an ui element around the z axis towards that object

slender nymph
#

why does the RemoveHealth method need to know about that indicator?

tender stag
#

it doesnt

#

just the object which it took damage from

#

the indicator is in another script

slender nymph
#

so make the object that is dealing damage alert the indicator instead of the removehealth method

tender stag
#

oh wait

#

true

#

thank you

Hi, my Unity is stuck on Application.EnterPlayMode

slender nymph
#

you probably have an infinite loop

sly wasp
#

Is it something wrong with my script? (I’ll send it in a sec)

#

!code

eternal falconBOT
sly wasp
slender nymph
#

yep infinite loop in your coroutine

sly wasp
#

Dang

#

Thx

slender nymph
#

also, you're using FindGameObjectWithTag in Update, this is not exactly ideal. just store the reference either in Start/Awake or serialize it so you aren't constantly using that method. it's not as bad as just a regular Find, but you really shouldn't need to be doing that every single frame

sly wasp
#

I do that cuz if I have a different hoverboard active it will detect it automatically

summer stump
#

Doing it every frame TWICE

summer stump
slender nymph
#

Player.GetComponent<Character>().HoverBoardActive == false
just make the Character component know which HoverBoard is active and grab it from that instead. also instead of using GameObject variables, use variables for the components you actually care about

sly wasp
#

I’m good

Gayyssss (ejem guys) is there any form to make the player still crouch if it has a roof/object above him because the roof is smaller than his normal height?

eternal needle
tender stag
#

do colliders get checked from parent to child?

#

or child to parent

slender nymph
#

checked in what way

tender stag
#

like if im doing this

Collider[] objects = Physics.OverlapSphere(transform.position, secondRadius);

foreach(var collider in objects)
{
if(collider.gameObject.layer == LayerMask.NameToLayer("Damageable"))
}

slender nymph
#

the parent/child relationship of colliders is not relevant here

#

OverlapSphere will return all of the colliders it finds in the area specified using whatever relevant search filters provided (in this case none)

#

also if you only care about objects on a specific layer, then use a layermask

unreal imp
slender nymph
#

yes a physics query like a raycast or overlapsphere would be used for that

tender stag
#

if a collider is set as a trigger, will the overlap sphere still detect it?

slender nymph
#

depends on your physics settings or the parameters passed to your query

eternal needle
#

not entirely sure if thats the same case here

wintry quarry
tender stag
#

im pretty sure i disabled it

#

which one is it

wintry quarry

"Queries hit triggers", as mentioned

Sadly, my school forces us to have some Visual scripts and some c# scripts in our first semester, meaining, im not really good with any of them and it kind of confuses me how i can reference stuff over different kinds of scripts. My first question is, how do i replicate what i have in the first screenshot in c#. and the second is, how can i read the "score" variable in the second screenshot in c#

this is the script i have. i have a bow and want to only be able to shoot if i have more than 0 arrows and every time i shoot an arrow, it should add -1 to the arrow amount (score)

the score itself should be Score

#

gameobject can be ScoreTracker or something like that

teal viper
#

Read the documentation

You don't wanna have a GameObject.Find in update either, you would cache the reference in start or a field in inspector

Seeing how you have trouble reading the docs.

Hello. I've got this problem I still couldn't resolve. I have a .txt file with 4 million words in it and my script is supposed to display a random excerpt from it when I press C. But the first time I press it, sometimes, but not every single time, the game freezes for a couple of seconds. How could I fix this?

This is basically my code. And I've yet to find a way to fix this.

I remember seeing you ask this before, but just curious why do you even need such a large file? What 4 million words could you possibly need

wintry quarry

The split is less of a problem than loading such a huge file in the first place

#

I/O is notoriously slow

#

They're stories and what not.

But you're just picking a random word

Script isnt loading for me so I cant see what you're doing with the file, I think you would have a better time splitting each story into it's own file

queen adder
#

Oh, I deleted it, sorry.

#

I'll repost it.

#

But won't that cause even more problems?

#

I mean, I could split the .txt file in 4, 10 or 40 files, but wouldn't cycling through them cause even more freezing problems? And even more often?

timber tide
#

well, depends how you're loading it all in

eternal needle
#

Why would you cycle through them? You just wouldnt be loading 4 million words at once, you would be loading way less

That coroutine also doesnt need to be a coroutine, since its just yielding after all the code has run

enable colliders, make rigidbody not kinematic when you want it to ragdoll, disable the main movement code

Hey yall i got a question.
In my current project i have a level select screen.

I opted to make it a scroll view so the player just has to scroll up to see new levels or down to see previous levels. (Something like the candy crush level layout).
My only issue is. Im trying to save the level that the player is currently on.
Eg. If they on level 50 and they exit the game and go back into the game i want the level to show as level 50. I dont want it starting at level 1 again and then they have to scroll all the way back up to level 50.

So does anyone know how i would be able to save the position of the current level the player is on?

My levels are not prefabs. They are images that have a button script on them. And i setup my level layout (type of board, goals, etc) in a scriptable object

Sorry for the bad explanation. Im not sure how to ask this question.

Im using unity and c#

# queen adder Hey yall i got a question. In my current project i have a level select screen. ...

Are these images contained under 1 parent/container or in an array that references the image in the scene? If so, you could use the level number as the index (with respect to 0-based), and scroll to the image at that lvl number, otherwise, you could save the Vector3 of the anchored world position if its UI, or world position otherwise, though I feel like there should be other ways you can compress your data aside from relying on 3 floating point values

I made my images in the content section.
I think my scriptable object for my levels is an array. Sorry i made that quite a while ago. So im not 100% sure.
I made a scriptable object called world. Then another one called level.
In my world SO i think i select how many levels i want the in my level SO i do the setup of my levels (moves, goals, layout etc).

So I'm making a game where you cook foods and give them to customers, I store the foods that are in your inventory as a list of gameObjects.

the better way would not be storing a game object at all, and just be storing the FoodScript directly. Otherwise, this seems relatively fine

storing a list of food script would avoid N get component calls

as for it moving really slow, you currently only move 1 unit per second because you are not scaling by a speed variable

scaling = multiplying

i suggest making it a controllable variable too, then you can think about adding walk speed, sprint speed, crouch speed, etc

does someone have a good video on making a self balancing ragdoll character all the videos I'm finding either don't help me or is not what I'm looking for

The general steps are to have an animated version of the player, then your ragdoll tries to copy the rotations. Movement likely would just be with AddForce

# honest idol mhm ok I'll work on other stuff then, thank you

If you do specifically need to use an active ragdoll, I can try to advise more on it. If you just need something that can ragdoll then what I said a bit above about enabling the ragdoll is a lot better. No matter how much I fine tuned my ragdoll, it never really looked clean with its movement. Theres a good reason active ragdolls arent in many games as the main character. Sometimes they are just animation driven, which I feel is no longer an active ragdoll because it wouldnt respond to forces then

Those games may look simple due to the goofiness, but trust me they are really difficult to make

#

From my experience as well, an active ragdoll is an absolute nightmare in multiplayer. I abandoned that project I was working on

Be prepared for a lot of head scratching. It's definitely an advanced topic

#

As bawsi explained, the usual way is to have a normal animated rig and another rig that copies the rotations from the source bones to the joints. This is where the methods I linked become handy
