[rich adder]

you literally know what assigning is lol

where is the miss

[muted wadi]

DiscThrow

[polar acorn]

Okay where do you tell the code that

[muted wadi]

DiscThrow throwB

am i wrong?

[summer stump]

Yes
That is not an assignment

[muted wadi]

damn

[polar acorn]

Okay where do you tell the code which DiscThrow that variable holds

[rich adder]

references are literally just telling the computer where to look for a particular thing .. if you don't its null..

[muted wadi]

i guess nowhere? I didn't know i needed to do that

how would I tell it which one it is

[polar acorn]

Then how is it supposed to know which DiscThrow you want

[polar acorn]

https://unity.huh.how/programming/references

[teal viper]

Need to learn about declaration/definition/initialization. Basically, go through C# basics...

[summer stump]

A script is a concept. You need to tell it the thing that actually exists. The objec
Edit: sorry, I guess that has been explained already

[rich adder]

without actual some basic c# this will just go in one ear and out the other (figuratively ofc)

[muted wadi]

is this as simple as just doing throwB = FindObjectOfType<DiscThrow>();

DiscThrow will only ever exist on one object so

[summer stump]

Yes, but that is the WORST way to do it.
Dragging the object into the inspector would be better if it exists before you click play

[muted wadi]

put in void start btw

[polar acorn]

If there's only ever one to exist why not just set the reference directly in the inspector

[muted wadi]

idk i guess im dumb

[rich adder]

not-informed yet*

https://unity.huh.how/references/serializing-component-references @muted wadi

[strong path]

so ive replaced "anim.Play" with animator.SetBool()

[SerializeField] public GameObject player;
    [SerializeField] private Animator anim;

    void OnTriggerEnter2D(Collider2D col)
    {
        if (col.gameObject == player)
            animator.SetBool("Collision", true);
            Debug.Log("Called");
            
    }```

now i get this error

(13,13): error CS0103: The name 'animator' does not exist in the current context

[polar acorn]

What is animator

[strong path]

the one in "animator.SetBool"

[muted wadi]

sorry i dont understand what you mean to show me with this. I think i already know about serialising variables

is there something im missing?

[summer stump]

Serialized references mean you can drag and drop the object into a box
You seemed confused by that part

[polar acorn]

What is animator

[strong path]

wdym

[muted wadi]

yup

[polar acorn]

I mean what I said

what is animator

[muted wadi]

i already knew that's what serialising does

[strong path]

there are two

[rich adder]

so why did we waste half hour on back n forth

[polar acorn]

I see zero

[summer stump]

This seems like the same idea as what Em is going through. Where do you declare and assign animator?

[muted wadi]

i mean idk i thought you were explaining something else

honestly im still lost as to what im doing wrong

[rich adder]

then you dont know what serializing really is or

[summer stump]

That says anim

[rich adder]

if you're not getting error highlighted here !ide (follow bot message)

[muted wadi]

serialising a private variable means i can protect that variable AND have it appear in the inspector, right?

[strong path]

from this; " [SerializeField] private Animator anim;"

[summer stump]

Yep

[muted wadi]

so what am i missing?

[polar acorn]

Okay, where is animator

[summer stump]

That is anim, not animator

[rich adder]

yes but WHY do we want it in the inspector

thats the true importance of reason

[summer stump]

Just that you should DO that, instead of Find

[strong path]

animator

[polar acorn]

Show the variable animator

where do you make it

where do you assign it

[muted wadi]

so that i can assign an object so that the reference is no longer nothing

[summer stump]

That... is... anim... not... animator

anim is a completely different word

[rich adder]

also Serializing doesn't just apply to private
[SerializeField] is just an attribute that Allows a variable to be serialized

[muted wadi]

sorry could you remind me what serialising means again

[rich adder]

alright well you finally got it so now you should know what to do

[polar acorn]

buddy

you just said what serializing is

Are there two people using your discord account or what

[rich adder]

lol

[summer stump]

I think it was sarcasm?
That confused me too

[muted wadi]

no please im just really stupid

[strong path]

where the animation trees are????

[rich adder]

its just a fancy word for putting everything in order

[polar acorn]

No, the variable animator

that you are trying to use

where did you make it

[rich adder]

in unity it exposes stuff in the inspector when its done so

[polar acorn]

where did you assign it

does it exist

did you make it

show where it is

[summer stump]

No.

You are literally just using the wrong word.
You wrote ANIM. but you are trying to use ANIMATOR. Those are different words 😂

public Animator anim
Is not
public Animator animator

[muted wadi]

so serialising just makes it appear in the editor?

[rich adder]

In the context of unity , yes

[muted wadi]

thank god i finally got that right

[rich adder]

serializing is done outside of unity as well but nothing you should worry about now

it just puts everything in order so the code can be stored

[strong path]

what about here

if (col.gameObject == player)
            animator.SetBool("Collision", true);
            Debug.Log("Called");```

[polar acorn]

That is where you are attempting to use a variable called animator

now

where did you make that variable

[strong path]

I DONT KNOW

[polar acorn]

then why are you trying to use a variable you haven't made

[strong path]

I TOOK THAT LINE FROM MY OTHER CODE USING BOOLS

[summer stump]

Yeah, that is USING it. Which is the error
You made a variable called anim, but you are writing animator in that code

[strong path]

my other code works like this

public CharacterController2D controller;
    public Animator animator;

    public float runSpeed = 40f;

    float horizontalMove = 0f;
    bool jump = false;

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

        horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;

        animator.SetFloat("Speed", Mathf.Abs(horizontalMove));

        if (Input.GetButtonDown("Jump"))
        {
            jump = true;
            animator.SetBool("IsJumping", true);```

[summer stump]

See the second line?

[strong path]

shit

[summer stump]

How it says animator

[strong path]

im sorry

[polar acorn]

So you see how you have a variable named animator here

and you do not in the other one

[muted wadi]

oh i just remembered why i didn't assign newBall a value in the ThrowDisc script through the editor. Its because in the ThrowDisc script, newBall is assigned the value of an instantiated object, so I have to leave it empty through the editor because it gets assigned when the ball is actually instantiated.

does that make sense?

{
    isReturning = false;
    throwReady = false;
    newBall = Instantiate(discPrefab, discSpawn.position, cam.transform.localRotation);
    ballRB = newBall.GetComponent<Rigidbody>();
    ThrowBall(newBall);
}```

[rich adder]

no it doesnt

cause ur error was never newBall

newBall has nothing to do with your error

[polar acorn]

What does newBall have to do with anything

[rich adder]

newBall assignment was just the catalyst to the underlying cause

[muted wadi]

oh goddamit

my project crashed

[strong path]

YES

YES

FINALLY

SUCH A PETTY MISTAKE OH MY GOD

THANKM YOU

[muted wadi]

guys honestly i really appreciate the help

im lost in another country with all this

[rich adder]

make sure to configure your IDE now cause it shouldve been highlighted from code editor for you

also my project just crashes now whenever i try to make the ball move to the items in the list

[rich adder]

recursive spawn i bet

[muted wadi]

its definitely some kind of infinite error loop or something

[muted wadi]

what is that

[polar acorn]

Are you spawning an object that spawns objects that spawns objects...

[muted wadi]

it should only be spawned once

also another question: do i need to specify an end to a coroutine?

[rich adder]

oh you touched something in a coroutine

[muted wadi]

yeah...

[polar acorn]

Show code

[muted wadi]

            throwB.newBall.transform.position = Vector3.MoveTowards(throwB.newBall.transform.position, hitList[currentHit].transform.position, t);
            yield return null;
        }
    }
}```

[summer stump]

No, unless you have a loop

Ah, which you do

[muted wadi]

so it will just end at yield return null?

[rich adder]

goes outside the if statement

in the while loop

cause your code may not ever hit that if statement thus never end the frame

[polar acorn]

If that condition in BailiffMove isn't met, it'll loop forever

Nothing can change so it can never become true to hit the yield

[muted wadi]

wait which condition

[strong path]

can i start a timeline as soon as the bool turns true

[rich adder]

the one that has yield return null

[polar acorn]

The distance check in BailiffMove

[solemn bobcat]

You can also break the coroutine with yield break; line.

[rich adder]

well maybe they wanna execute code after the loop

[muted wadi]

but i dont understand, shouldn't it be moving if its not close enough?

[polar acorn]

Where inside the while loop is it moving

[rich adder]

isn't this the code from earlier ?

[muted wadi]

yeah lol, my dumbass is still stuck here

[rich adder]

i give u some of this no? note where this is

[muted wadi]

im sorry could you explain

[summer stump]

yield return null waits a frame then continues. It does not stop.
And yeah, you want that outside the if statement

[rich adder]

you're using VS so we can't even blame poor brackets lmao

[rich adder]

without yield return null the coroutine never finishes the loop

so you're stuck forever there

[muted wadi]

oh is the yield return null meant to be outside the if statement

[summer stump]

while (x)
{
  if (y)
  {
    //yield here if you want. Optional
  }
  //yield here definitely
}

[summer stump]

Yes, absolutely

[rich adder]

it tells the while loop that frame has ended, go to the next

[muted wadi]

OH

okay yeah i see now

[polar acorn]

Let me put it this way:
You start the while loop.
You check if the distance is less than 0.8
It is not, so you skip to the end of the loop.
You begin another iteration of the loop.
You check if the distance is less than 0.8
It is not, so you skip to the end of the loop.
You begin another iteration of the loop.
You check if the distance is less than 0.8
It is not, so you skip to the end of the loop.

[open veldt]

Haiii Quick question I need to see if something I’m thinking of will work;

Can classes derived from an abstract class be assigned to a variable with the type of the abstract class?

[polar acorn]

Yep

[open veldt]

LETS GOO

Thanks

[rich adder]

the whole point of inheritance

lol

[open veldt]

Just had to make sure idk why I thought I saw something that said it can’t

[polar acorn]

And if you need to get to that derived class from the parent class, you can do a checked cast:

if (theAbstractVariable is DerivedClassName derivedVariable)

[open veldt]

Me when the coding solutions hit me while folding laundry

[open veldt]

Ohh thats cool thank you :)

[polar acorn]

It checks if it's that type, and if it is, assigns it to a variable you can use inside the if statement

[open veldt]

Thanks!!

[muted wadi]

my brain must be full of holes

[rich adder]

me trying to learn something like Haskell

[summer stump]

Haskell is great

[rich adder]

it is just breaks my brain sometimes

[muted wadi]

now im getting this error

this must be to do with the hitList

[rich adder]

it tells you the line

53

lockOn

[austere monolith]

https://hastebin.com/share/jeqogomovu.csharp

i cant look on the y, what did i do wrong?

[muted wadi]

@rich adder that line gets the currentHit index from hitList, which is first set to 0

[rich adder]

dont use Time.deltaTime on mouse

[muted wadi]

if (Vector3.Distance(throwB.newBall.transform.position, hitList[currentHit].transform.position) < 0.8f)

[rich adder]

whats value of currentHit then

clear its more than list contains

[austere monolith]

that wasnt the problem

[rich adder]

I never say it was, but you should still not use it

[muted wadi]

the value at that moment is 0

[austere monolith]

ok

[rich adder]

where do you do anything with Y

transform.localRotation = Quaternion.Euler(0f, 0f, 0f);

[rich adder]

not at the moement, when you try to use in that if statement

[muted wadi]

but why is there an error?

[summer stump]

What is in the hitList?

[rich adder]

send new script

[muted wadi]

everything that is caught in the ray while the player is holding right click

[muted wadi]

{
    throwB.isReturning = false;
    throwB.throwReady = false;
    throwB.newBall = Instantiate(throwB.discPrefab, throwB.discSpawn.position, throwB.cam.transform.localRotation);

    while (bailiffActive)
    {
        if (Vector3.Distance(throwB.newBall.transform.position, hitList[currentHit].transform.position) < 0.8f)
        {
            if (currentHit < hitList.Count - 1)
            {
                currentHit++;
            }
            else
            {
                throwB.RetrieveDisc();
                break;
            }
            float t = 10 * Time.deltaTime;
            throwB.newBall.transform.position = Vector3.MoveTowards(throwB.newBall.transform.position, hitList[currentHit].transform.position, t);
        }
        yield return null;
    }
}```

i haven't changed anything except for the yield return

[rich adder]

where do you set currentHit

for the first time

[summer stump]

show where you do that

[muted wadi]

{
    // MAKE CLASS A SINGLETON
    
    public List<GameObject> hitList = new List<GameObject>();
    public DiscThrow throwB;
    int currentHit = 0;```

[rich adder]

also you probably are calling this before you do that

so there is nothing in list

[summer stump]

This is an assignment by the way! You assign a new empty list to hitList

[muted wadi]

private void Update()
{
    if (Input.GetKey(KeyCode.Mouse1))
    {
        FireRay();
    }
    else if (Input.GetKeyUp(KeyCode.Mouse1))
    {
        foreach (GameObject go in hitList)
        {
            go.GetComponent<LockedOnVisual>().VisualMarker(false);
            
        }
        bailiffActive = true;
        StartCoroutine(BailiffMove());
        hitList.Clear();

        Debug.Log(hitList.Count);
    }
}

void FireRay()
{
    RaycastHit hit;

    if (Physics.Raycast(rayOut.transform.position, rayOut.transform.forward, out hit, maxDist, hitLayer))
    {
        if (!hitList.Contains(hit.transform.gameObject))
        {
            hitList.Add(hit.transform.gameObject);

            hit.transform.gameObject.GetComponent<LockedOnVisual>().VisualMarker(true);
        }

    }
}```

[muted wadi]

im declaring and assigning in that line right?

[summer stump]

yep

[muted wadi]

okay cool

[summer stump]

it's possible for you to NOT put something in hitList, but still run the coroutine and have it check an empty list

[muted wadi]

goddamit

[rich adder]

fun fact when you do publicand [SerializeField] private a list/array Unity already new()

[muted wadi]

thats what i thought the problem was

[rich adder]

still good habit to write it though

[summer stump]

if you hit mouse1, it fires a ray, if it hits something that is NOT in the list, it will add it, then you check the list with no guarentee that it actually hit something

just do an if (hitList.length > 0) before checking it

[muted wadi]

thank you

[rich adder]

.Count

cause its a list

[muted wadi]

also i would do that before vector3.distance right?

[austere monolith]

i watched a brackeys tutorial

[muted wadi]

just wanna make sure

[austere monolith]

so i dont know where im using Y

[rich adder]

look at your code again

[summer stump]

dang it! I still always mix them up and don't know why hahaha.

[rich adder]

if you're not using it why would anything rotate on Y ?

[austere monolith]

idk where i can

im nub

[rich adder]

i do it too sometimes

[muted wadi]

{
    if (hitList.Count == 0)
    {
        if (Vector3.Distance(throwB.newBall.transform.position, hitList[currentHit].transform.position) < 0.8f)
        {
            if (currentHit < hitList.Count - 1)
            {
                currentHit++;
            }
            else
            {
                throwB.RetrieveDisc();
                break;
            }
            float t = 10 * Time.deltaTime;
            throwB.newBall.transform.position = Vector3.MoveTowards(throwB.newBall.transform.position, hitList[currentHit].transform.position, t);
        }
        yield return null;
    }
    yield return null;
}```

please tell me i got it right this time

[rich adder]

werent u watching a video

follow it again, im sure it works there, just skip the Time.deltaTime

[rich adder]

no

[muted wadi]

😭

[rich adder]

you're saying if count == 0 run this

nt what i wrotelol

[ivory bobcat]

current hit is a value that isn't within range of your list/array

[muted wadi]

oh shit

i can just do != instead right?

[rich adder]

just use what Aethenosity wrote

[summer stump]

Since it can't be negative, yeah that should be fine

[strong path]

is there a way for the camera to follow the player without moving its y axis

[muted wadi]

sorry that was just me being tired

[austere monolith]

kk i see how i messed up

[muted wadi]

i promise i at least understand that basic stuff

[austere monolith]

transform.localRotation = Quaternion.Euler(0f, 0f, 0f); instead of having xRotation, 0f, 0f

[muted wadi]

okay so now the ball gets instantiated but it doesn't actually move towards the targets

[strong path]

can two animations play at the same time for the same sprite

like this

[summer stump]

The error was happening because you never hit anything.
You are still not hitting anything, you just make sure that doesn't cause an error

[summer stump]

Blend trees I guess?
More of an #🏃┃animation question

[strong path]

oh mb

sorry

[muted wadi]

it doesn't cause an error anymore

[summer stump]

That's what I said

[muted wadi]

oh

sorry i know im being a hassle for everyone

[gaunt basin]

Why does this code not work?

im trying to make an object collide with an object but imnot getting a debug

[muted wadi]

every time i go to program its like im back to square 0 and know nothing

[elder atlas]

is it debugging the first hi

[summer stump]

You're fine!
The issue is just that you don't hit anything, so there is nothing to move to

[gaunt basin]

nope

[elder atlas]

does both objects have a collider

[gaunt basin]

Both have a box collider 2d yeah

[muted wadi]

no wait but i am though, i know for a fact im adding objects to the list

[gaunt basin]

wait I'll send you the full code

[summer stump]

How do you know that for sure?

[muted wadi]

because the objects in the list get a visual marker in the scene, so i know they're in the list

the OnCollisionEnter2D method should be outside of update

they're both monobehaviour broadcasts

[gaunt basin]

ohhhh

works thanks

[elder atlas]

np

[gaunt basin]

i wasted 3 hours trying to code an entire physics system >_<

its fine though

[elder atlas]

dw you'll spend many hours on dumb issues its just the nature of programming

[summer stump]

Ok then. Use some Debug.Logs to figure out where the code gets to in BailiffMove or whatever that was called

[muted wadi]

wait

i might know the issue

i have a hitList.Clear right after my BailiffMove coroutine. Could that be called before the coroutine is over or no?

[teal viper]

It could, yes.

[muted wadi]

i'll try and remove that for now

holy christ

ah of course

its in the update function

[gaunt basin]

okay next question, so I have a bullet object, and I've assigned a tag to it and there's code that makes it so that whenever it touches an enemy it sends a line of debug, however its not working

1. The tag did work on another object (my player character) and the collisions worked perfectly fine
2. both objects have a box collider 2D

any ideas?

[muted wadi]

i had an issue like this once, send your code if you haven't already

[gaunt basin]

void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("bullleft"))
    {
        Debug.Log("Hi");
        Destroy(gameObject);
        Destroy(collision.gameObject);
    }
}

this worked perfectly fine on my player character but didn't work on my bullets

code applies to the enemy btw

the collisions also work I changed my bullet's sprite to my character sprite and my player is getting pushed back

[rotund hull]

does it log anything

[gaunt basin]

nope

[muted wadi]

so this is meant to destroy both the bullet and the enemy?

[gaunt basin]

yeah

not sure if the destroying part works but its supposed to debug a line of code thats the part im trying to work out

[rotund hull]

try just collision.CompareTag

[gaunt basin]

the collision itself is broken the tag is not

ill send a pic of the bullets components and the enemy's 1 sec

[rotund hull]

ok

[gaunt basin]

the bullet's

[muted wadi]

is the tag assigned?

[gaunt basin]

the enemy's

yeah it is

[rotund hull]

just try collision.CompareTag

[gaunt basin]

wym?

does this return a collided object?

[muted wadi]

instead of collision.gameobject

[rotund hull]

in the if statement

[gaunt basin]

the problem isn't with the tag though

I added another debug line above the tag comparison and it still doesn't work

I added a 2D collider to my player object and gave it the tag and it did work there's just something wrong with my bullet object

[rotund hull]

make sure it is spelled like this OnCollisionEnter2D(Collision2D)

[gaunt basin]

returns an error

[muted wadi]

could it be because its not OnColliderEnter2D

[rotund hull]

it is not

[muted wadi]

correct me if im wrong but isn't it Collider not Collision

[rotund hull]

i checked on the unity site

collision2D needs a name

try to give it a name

[rotund hull]

colision

[muted wadi]

is it collision for 2D and collider for 3D

[gaunt basin]

i named it collision and like i said it didnt work, there's something very strange I wonder if putting it under the player in the hierarchy fixes it though

[rotund hull]

collider is for triggers

[muted wadi]

isn't it OnTriggerEnter though?

[rotund hull]

it is but it is like this OnTriggerEnter2D(Collider2D collider)

[rotund hull]

that is werid

[rotund hull]

try to rewrite the oncollsionenter2D code and make sure that it is collision.CompareTag instead of collision.gameObject.ComparTag

[gaunt basin]

the code shouldnt be the problem it detects the player when i added a box collider 2d to it

i probably made a mistake somewhere down the line

[rotund hull]

can i see the code you have the collsion code in

in this

[gaunt basin]

OH MY GOD i figured it out

[rotund hull]

what was it

[gaunt basin]

you need to have a rigidbody2d component as well

[rotund hull]

that makes sence

[gaunt basin]

yeah lol

[rotund hull]

if you dont want the player to move though make it static

[gaunt basin]

cool thanks

[rotund hull]

no problem

[gaunt basin]

how do you completely block out gravity for the rigid body objects btw?

[rotund hull]

are you making a topdown game

[gaunt basin]

nope a platformer

[rotund hull]

ohhhh

[muted wadi]

just turn it off on the component

[rotund hull]

sorry

no you need it for collsion

turn the rigidbody back to dynamiv and set the gravity scale to 0

[summer stump]

One of the two objects needs a rigidbody OR a charactercontroller

[summer stump]

You can make it kinematic, but that won't work for OnTriggerEnter
Could set gravity scale to 0

[muted wadi]

really?

[rotund hull]

that makes it 0 gracity

gravity

[muted wadi]

but that shouldn't be an issue for collisions right?

[rotund hull]

no

you just need a rigidbody

doesnt matter what you do to it

unless its ontriggerenter'

[muted wadi]

strange

[rotund hull]

eyah

yeah

[muted wadi]

i guess i haven't used 2D that much

[rotund hull]

i always use 2d

[muted wadi]

fair enough

[summer stump]

It's the same for 3d

[rotund hull]

oh

[boreal tangle]

does someone know why when the player jumps they can no longer control their horizontal movement
https://gdl.space/iwipifexuq.cs

[modest barn]

A basic one here:
https://docs.unity3d.com/Packages/com.unity.textmeshpro@1.3/api/TMPro.TMP_InputField.html

How can I set an input field to that greyed-out, disabled state that means that a user can't edit the input field (the type of state that you see all over the internet)? I can't find it at the above link.

[muted wadi]

but you can turn off gravity in 3D rigibody and collisions will still work

[summer stump]

@boreal tangle You only get horizontal input when grounded

[modest barn]

Wrong one 🙂

[summer stump]

Grounded = isGrounded();
    horiMovement = Input.GetAxisRaw("Horizontal");

[summer stump]

Oh, wrong code?

OHHHH

[modest barn]

Are you meant to be talking to me?

Haha

[summer stump]

wrong person

lmfao

[modest barn]

You need some sleep

[rotund hull]

yes

[summer stump]

Nah, it just jumped when I clicked reply

[summer stump]

Same in 2d

[boreal tangle]

Whats wrong with that part of the code?

[muted wadi]

thats what i said brah

[rich adder]

can you not do .enabled =false ?

[summer stump]

You said "but"

[summer stump]

You disable horizontal movement. You were wondering why it didn't work.That is why

[muted wadi]

god im tired

[rich adder]

        inputfield.enabled = false;
        inputfield.interactable = false;```

[modest barn]

It's not in the documentation - this is a TMP Input Field, maybe you're thinking of the legacy one?

[rich adder]

either of these should work

[modest barn]

Ok I'll give them a try.

[boreal tangle]

how is it disabled. Horizontal checks the axis and in fixedupdate it changes velocity in the x direction regardless if the player is jumping or not.

[rich adder]

no its because TMP_InputField inherits from Interactable

which is base class for the UI stuff

[boreal tangle]

it isnt

[summer stump]

Dang, that formatting got me

[boreal tangle]

oh

[summer stump]

Fix that lol

[boreal tangle]

ok

[summer stump]

I think I will leave haha. Like three mistakes in a row. Sorry for the confusion

[modest barn]

@rich adder

[SerializeField] TMP_InputField secondaryInputField;

private void Start()
{
    secondaryInputField.enabled = false;
}

NullReferenceException: Object reference not set to an instance of an object

But I thought that the InputField would be an instance because it's been created in the scene

[slender nymph]

that means you didn't drag the input field into the slot in the inspector

[rich adder]

the script has no idea which TMP_InputField secondaryInputField is

[modest barn]

Oh... it was definitely there before as my code uses it, and then I renamed the GameObject. I thought that Serializing fields protected issues with renaming? Oh well, I dragged it back in

[rich adder]

yes

[boreal tangle]

can you tell me

[rich adder]

look for a moment what this is doing when you jump ```cs
rb.velocity = new Vector2(horiMovement * movementSpeed, rb.velocity.y);
if (toJump)
{
rb.velocity = new Vector2(rb.velocity.x, 5);

 toJump = false;

}```

[queen adder]

can someone explain me what Mathf.Atan2 is

[rich adder]

code runs top to bottom btw

[boreal tangle]

ik

[ivory bobcat]

Did you try looking at the docs?

https://docs.unity3d.com/ScriptReference/Mathf.Atan2.html

[rich adder]

so what happens to your velocity after you press keys mid-air

[queen adder]

yep but idk what a radian is

[verbal dome]

Is it from a script that makes the player look at the mouse perhaps?

[queen adder]

yes

[boreal tangle]

I dont see it. toJump should be false and the keys should act as normal

[rich adder]

radians is measuring circle

= radius

[ivory bobcat]

https://www.mathsisfun.com/geometry/radians.html

[rich adder]

very smart people thought its better to get angles this way

[queen adder]

oh

[verbal dome]

You can just do Vector3 direction = lookPosition - transform.position
Where lookPosition could be camera.ScreenToWorldPoint(Input.mousePosition), for example.

[queen adder]

i get it now

[verbal dome]

Then do transform.right = direction
Or transform.up/.forward depending on your game

[boreal tangle]

the only thing I can think of is that rb.velocity.y would be 5 forever

[rich adder]

oh didnt realize toJump was one frame bool, make sure of that.

[boreal tangle]

what do you mean by one frame bool

[rich adder]

wait you are saying they can't move horizontal right ?

[queen adder]

i made the code work thx

[boreal tangle]

When I press the UpArrow the player jumps. I used the input manger horizontal axis for horizontal movement and when I press the keys for left and right the player does not go left or right.

[ivory bobcat]

You're overriding velocity. So if you aren't pressing forward anymore, it'll completely stop relative to the x component.

If you're pressing right and left but it isn't moving, likely your keyboard might be limited.

[boreal tangle]

even if I contiue to press left or right the palyer doesnt move after jumping

[ivory bobcat]

Are you pressing more than one key?

[boreal tangle]

no

[ivory bobcat]

Log if left and right are being pressed. If hitting new keys disable older input, you may have a case of https://www.quora.com/Why-cant-I-press-more-than-three-buttons-on-my-keyboard-while-playing-a-video-game

[boreal tangle]

ok il check

[modest barn]

The referenced script (Unknown) on this Behaviour is missing!

Is there a way to find out where this is happening?

[gaunt ice]

script was renamed/the script was edited in play mode

[modest barn]

Oh I was in play mode 😂

Oops

[wanton hearth]

I think I'm going insane? Why is this giving errors?

[slender nymph]

put it inside of a method

[wanton hearth]

who would've thunk it...

[gaunt ice]

btw are you having two monobehaviour on one script?

[wicked cairn]

in addition to his answer. if you dont want it in a function and need it to be that number by default you would have made the original longer like public int testInt = 1;

[wanton hearth]

Yeah this was just my biggest brainfart ever. I am making a script file with multiple classes in it, which is something I'm not used to doing, so my brain was treating them like they were methods or something, haha

[wicked cairn]

If you didnt know tho, you can reach other scripts from one script without making another class inside it

with just public TheOtherScript something; then in a function youd do something.testFunction();

[wanton hearth]

Yeah, I know about it, thanks.

[floral bloom]

hey i got a if statement that loops anyone able to assist me?

[rich adder]

with what?

[floral bloom]

i have it so when i press tab and bool is false it opens then bool turns to true
and another else if statement for when its true
but pressing tab loops both and i get 50 logs for each if statement

[gaunt ice]

are you using getKey not getkeydown or up?

[floral bloom]

lol

yes

[rich adder]

show code

[floral bloom]

ffs

you were right

is there any good books for learning unity code, im getting nothing from watch videos

[rich adder]

ups

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/tutorials/

[floral bloom]

https://www.w3schools.com/cs/index.php i went threw this to learn the basics

[rich adder]

yeah

thats good

keep doing it

[summer stump]

There are also resources pinned on this channel.
Catlike coding is good

[floral bloom]

ill give them a look tysm

[formal escarp]

hey guys sorry dumb question but im not trolling.

Destroy(gameObject); will destroy the gameObject alright. Destroy(transform.parent.gameObject); will destroy the parent, but what if you have an empty object por example, a child, and a child of that child like. you can also destroy the "grandparent" (name is dumb but not sure what it would be called)

[cosmic dagger]

honestly, i read rb whitaker's beginner and intermediate c# tutorials. i was good after that . . .

[timber tide]

pretty much grandparents, ect

[cosmic dagger]

destroying the GameObject also destroys any children of that GameObject . . .

[formal escarp]

They are a totally different thing right? and that would mean you need to make another call to destroy it (although, i do not want to destroy it but im just curious as im experimenting with destroying children and parent)

[summer stump]

You can chain parents
transform.parent.parent.parent.parent.etc

Oh, did you mean the other direction?

[formal escarp]

Yeah. I had 3 gameobjects. "FolderItem" "Item" "Trigger" The trigger would be the "grandchild" and had a destroy. but i also wanted to destroy the "Item"

but i was wondering how it would go if i wanted to destroy the "FolderItem" out of curiosity.

[summer stump]

It would destroy everything

[formal escarp]

and what is the name of that in the case.

[timber tide]

chopping the root will usually just kill it all

[formal escarp]

yeah, i was killing it from the smaller thing, not the main parent.

[timber tide]

oh yeah you can use tree terminology too if you want ;)

[summer stump]

Grandparent is usually what it's called. Or root if there are no parents beyond it

[timber tide]

root, leaf, branch

[formal escarp]

i mean.

[cosmic dagger]

#💻┃code-beginner message

[formal escarp]

i did not wanted to kill the "main thing" just the smaller ones.

[formal escarp]

this is the chat.

[summer stump]

Then just destroy Item

[summer stump]

It is a specific message

[formal escarp]

I cant.

[summer stump]

Oh? Why?

[formal escarp]

The "Item" has a rigidbody and gravity, if i put on "IsTrigger" too it breaks and goes underground. So i had to add a child to the "Item" and give THEM the "IsTrigger"

[summer stump]

Do you want to preserve Trigger? You'd have to reparent it

[summer stump]

You can have more than one collider on the same object, but yeah, what you did makes sense

[formal escarp]

wait wait. you can have more than one collider?

[cosmic dagger]

that doesn't make sense . . .

[summer stump]

Of course

[formal escarp]

WOW. I did not knew that.

[formal escarp]

I mean, the way i did it works. And i just needed to add 1 line of code.

[summer stump]

You wouldn't be able to differentiate them though. That is why people often stick them on children with their own scripts.
(Like one for sight, one for hearing, etc)

[formal escarp]

ooohh.

thats cool

thanks for the info man.

Does anybody see anything in my code that might make me fall through my floor? I keep collision with it like 90% of the time, but certain triggers like jumping too high, or colliding with the sides of objects makes my player fall right through. https://gdl.space/opuxeceril.cpp

[summer stump]

Show the rigidbody inspector

[proper flume]

For the floor or my character? I tried adding a rigidbody to the plane, but it says that the plane mesh isn't compatible since Unity 5.

[summer stump]

The player.
And yeah, you don't want one for the plane

[summer stump]

Turn collision detection to continuous

And interpolate to interpolate (instead of none)

[proper flume]

That worked! Thanks. I'm still going through the Learn.Unity.com stuff and this is supposed to be my "project." When they explained how to set up a side-scroller none of that was mentioned though. 😅

[summer stump]

Also put Move() in FixedUpdate()

[summer stump]

Ahh yeah. It is more costly to do those things, but whenever you have collision issues it's a good thing to do

it is more of an issue if moving kinda faster. As you saw it wasn't ALWAYS an issue

[proper flume]

Ah, that's a good knowledge. I appreciate it.

[craggy bane]

Hello I'm trying to make a quest goal script

This is my script

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

public class QuestGoal : MonoBehaviour
{
  public GoalType goalType;
  public int requiredAmount;
  public int currentamount;

  {
    return (currentamount >= requiredAmount);
  }
  public void GatheredTrash()
  {
    if (goalType == GoalType.Gathering)
    currentamount++;
  }
}

public enum GoalType
{
    Gathering,

    
}

i want it to show up like this

[wintry quarry]

It shouldn't be a MonoBehaviour then

[craggy bane]

thanks

[cerulean crypt]

In a 2d game, what's the best object to detect collision but not to bump into other objects? I'm kinda new to collision stuff

[craggy bane]

I added the goal but I want it so that each time I click plastic the current amount goes up but it isn't

[summer stump]

A collider set to isTrigger
Or use a spatial query like raycasting/overlapsphere/checkbox/etc

[cerulean crypt]

Ahhh thank you!

Yh, Imma use the isTrigger var, thanks!

[summer stump]

Is plastic a button? If yes, Did you subscribe to the OnClick callback? If yes, Do you have an EventSystem in the scene?

[craggy bane]

yes its a button

[craggy bane]

Yeah

i have an event system

but I don't think i subcribed to the callback

can you teach me how?

[summer stump]

Show the buttons inspector

[summer stump]

So you subscribed to five things there

[craggy bane]

Mhm

[summer stump]

Which object has the script with this code?

[craggy bane]

Player

W guess

[summer stump]

Ok, so click the plus right there

And drag the player object into the new box

[craggy bane]

is this what I'm supposed to do?

[summer stump]

Yep!

[craggy bane]

Thanks

[summer stump]

If picktrashup is what you want of course haha

[craggy bane]

wait

Nevermind

I want the current amount to go up by 1

I need to add this after the onclick function right?

OH nevermind it works now

[true heart]

i have a list of strings and i was wondering if i wanted to find out what string was placed 1st or 2nd item of the list how woudl i do that

[summer stump]

myList[0] to get the first item, myList[1] for second?

[true heart]

oh i see

[summer stump]

not sure I fully understood though. Is that what you wanted?

[true heart]

well im trying to have a for loop that checks all items and then summons a prefab for each so i could use mylist[i] to find what each thing has

i think that woudl work maybe

[summer stump]

That would be the way to do it, yes

[cerulean crypt]

https://hastebin.com/share/unuxesajen.csharp hi im making a tower defense game and this script is in the tower. i need help because whenever i place a tower (or multiple it doesnt matter) after a while the tower will just stop doing damage to the enemy. it still has the enemies that it is attacking in the list of enemies in range, but it doesnt attack it. there are no errors so i dont know whats wrong

[nimble scaffold]

Hey can anyone help me with the problem that to switch a camera with right click ... The code worked but in game view it's saying no camera found but all things are attached to the script

using UnityEngine;

public class CameraSwitch : MonoBehaviour
{
    public Camera mainCamera;
    public Camera secondaryCamera;

    void Start()
    {
        // Ensure only the main camera is active initially
        mainCamera.enabled = true;
        secondaryCamera.enabled = false;
    }

    void Update()
    {
        // Check for right mouse button press
        if (Input.GetMouseButtonDown(1)) // 1 represents the right mouse button
        {
            // Switch between cameras
            mainCamera.enabled = !mainCamera.enabled;
            secondaryCamera.enabled = !secondaryCamera.enabled;
        }
    }
}

code not working its saying that display 1 no camera found

[slender nymph]

you should consider using cinemachine

[nimble scaffold]

Now I have given the comments also

So that's u all can understand

And pls help me

[nimble scaffold]

For cam switch?

[true heart]

so i tried to use tags to identify each item then make it equal to a certain object but it wont work. so how would i make the gameobject change to what item it has to be so i can instansiate it

[slender nymph]

yes. for all of your camera needs

[nimble scaffold]

Is there anything wrong with the code?

[slender nymph]

i have 1 single camera in my scene, but i can switch the view by simply enabling/disabling different virtual cameras and cinemachine does the hard part of transitioning between them for me

[slender nymph]

you cannot store an array of GameObjects in a GameObject variable

[summer stump]

The type on that line is wrong, as boxfriend said

[nimble scaffold]

But how?

[slender nymph]

by using cinemachine and enabling/disabling different vcams

[nimble scaffold]

Can you please provide me the code

[summer stump]

When you disable one and enable another, it moves the camera for you. That's how cinemachine works

[true heart]

ya im trying to find what item has the same tag as an item name on the list then instantiate it. so if how i wrote it dont work how would i go about that

[summer stump]

This works by changing priorities, but here:
https://michaellandonhatfield.medium.com/switching-between-virtual-cameras-in-unity-cinemachine-4fe7ab16d249

[summer stump]

GameObject[] is how you write an array of GameObjects

[true heart]

oh should so i shouldnt use a list of strings

[nimble scaffold]

So is it good for switching between my nirmala fps cam and sniper gun cam? And do I also need to change the normal fps cam to cinemachime

[true heart]

ican just make a list of gameobjects straight away i see

[summer stump]

Well... I guess? Are the strings different?

Do you have multiple objects with each tag?

[true heart]

no not really i wanted to connect all of them to a gameobject

na

all have there own tags

[summer stump]

Then yeah, I guess not.
But I recommend avoiding using Find at all honestly

[true heart]

oh really is it laggy or something

[summer stump]

https://unity.huh.how/references

[nimble scaffold]

@summer stump

[summer stump]

It is costly yes, but also error prone. The tag version is better though

[summer stump]

Is what good? Cinemachine? Yes, that's what it's made for.

[true heart]

should i make a reference to all of the prefabs in my script and acess them there then

[nimble scaffold]

Thanks sir

[rocky gale]

https://hastebin.com/share/unuxesajen.csharp hi im making a tower defense game and this script is in the tower. i need help because whenever i place a tower (or multiple it doesnt matter) after a while the tower will just stop doing damage to the enemy. it still has the enemies that it is attacking in the list of enemies in range, but it doesnt attack it. there are no errors so i dont know whats wrong

[summer stump]

Yeah, that would be better for sure.
Find won't find prefabs anyways. A prefab is an asset, it doesn't exist in the scene. It only finds gameobjects which have been instantiated or placed (which is just instantiating too) in the scene

[true heart]

oh i didnt even know that tags couldnt do that thank you for the help

I first tried the one with the rigid body, then tried it with the trigger. Which should it be?

Either. The physics message is sent to both
Just making sure it was on one of those two and not a child or something

Go through this:

Ooh thanks a lot, this worked

What fixed it was using OnTriggerEnter2D. I'm assuming it assumes 3D?

OnTriggerEnter IS 3D

not just an assumption

Sorry yh that's what I meant

Anyway thx for the help

        {
            CameraThree ();
        }
    }

    void CameraOne()
    {
        Camera1.SetActive(true);
        Camera2.SetActive(false);
        Camera3.SetActive(false);
    }

    void CameraTwo()
    {
        Camera3.SetActive(false);
        Camera2.SetActive(true);
        Camera1.SetActive(false);  
    }

    void CameraThree()
    {
        Camera3.SetActive(true);
        Camera2.SetActive(false);  
        Camera1.SetActive(false);
    }
}

Will this code work?

[summer stump]

I don't see the issue, but I have a few questions:
In your coroutine, why have the while loop? You always yield break on the first iteration.

What is TowerHover?

Why set the local scale to rangeSize instead of the radius of the collider or something?

Why is RangeDetectionAndDamage updating the enemy health?

And lastly, have you tried using the debugger or adding debug.logs?

Also, seems like you do an early return in update if EnemyStats is null. That may be the issue. Naaah, the physics message would still get new ones. So that isnt it

[rocky gale]

1. good question

2. it is the script that makes it so when you click the gui of the tower you can "hover" it and place it where you want

3. i didnt know how to set the size of the range

4. because im updating the health of the current enemy its attacking which is losing health

5. a little bit i definitely should more lol

[nimble scaffold]

using UnityEngine;

public class CameraScript : MonoBehaviour
{
    public GameObject Camera1;
    public GameObject Camera2;

    void Start()
    {
        
        Camera1.SetActive(true);
        Camera2.SetActive(false);
    }

    void Update()
    {
        if (Input.GetMouseButtonDown(1)) 
        {
            SwitchCameras();
        }
    }

    void SwitchCameras()
    {
        if (Camera1.activeSelf)
        {
            Camera1.SetActive(false);
            Camera2.SetActive(true);
        }
        else
        {
            Camera2.SetActive(false);
            Camera1.SetActive(true);
        }
    }
}

Guys pls say will this code work or not

[summer stump]

4. EnemyStats should have its own TakeDamage(float damage) method and update its own health probably. Separation of concerns can be very helpful.

5. I would throw a debug in there to check the isDead value of the enemy to see if that's part of the issue

[summer stump]

Why can't you just try it? You will know if it works or not by just trying

[nimble scaffold]

I'm in my mobile rn

[rocky gale]

yea thats definitely a better idea ill try. thanks

[summer stump]

Ah, then just wait till you're on your computer

[nimble scaffold]

Okay

Sir

[summer stump]

is TowerHover ever destroyed? TowerHover.isPlaced is a condition in OnTriggerStay, if that becomes false, you cannot attack

[rocky gale]

no its in the tower so it is just there

[craggy bane]

hi how do I make a text popup after completing a quest?

[summer stump]

Ok, hmm. I'm not sure then
Are the enemies dying? Is the tower ATTACKING, just not doing damage?

[summer stump]

myText.enabled = true;

[craggy bane]

like this?

[summer stump]

sure. if completed is some text or ui that you want to be enabled

[craggy bane]

Yeah

[rocky gale]

the enemies that the tower kills get disabled. i dont believe its attacking because in my script i also make the tower face the enemy it is currently attacking which it is not

[summer stump]

So, you can go that way, with ui elements there but disabled, then enable them at the right time. Or you can go another route where you Instantiate a ui element at the right time.
It depends. I usually do a combination.
For example, I have a panel that would pop up, and I would write custom text in it, and maybe create some icons

[craggy bane]

instantiate would be better right?

because everytime you complete the popup comes up

[summer stump]

Ahhhh, if they are disabled... then maybe it is trying to continue attacking that enemy?

Maybe make a public target variable and keep an eye on the inspector to see if it still has the old one

[summer stump]

If every time you complete a quest the popup comes up, then instantiate would be worse. Creating a whole new object each time when you can just modify the text is worse imo

[rocky gale]

when it dies it is removed from the list

[craggy bane]

Oh

[rocky gale]

i think im gonna try doing what you said of handling the damage in the actual enemy maybe that will fix it

[summer stump]

Ok, I just think it would be worth it to verify that. I see that you check an isDead value, but I dunno.

Other than that, I'm not sure at all. Sorry

[rocky gale]

alr ill try thx for the help\

[rocky gale]

i just got rid of the while loop and yield break and it works perfectly lol! thx so much if you didnt mention the loop being there for no reason i wouldve never thought of it

[summer stump]

Really!? That is weird! I just thought it was interesting, I didn't think that was the problem haha
Well, glad you got it!

Ohhhhh. I bet I know the issue

You called break early on some condition (can't remember)

It must have broken there, and then never got to the part where you set the bool false again, and this could not start another attack

[rocky gale]

ohhhhh

that makes sense

yea i honestly have no idea why i had that in there

[craggy bane]

error CS0103: The name 'Completed' does not exist in the current context

how do I fix this

boolean?

[summer stump]

Well Completed is simply not a thing

So you have to make it

Did you make a variable called Completed you are expecting to use? It may be local or something, or you forgot to make it

[craggy bane]

i don't know which one to make

I want it to popup after finishing the quest

[summer stump]

Well, I don't either haha

[craggy bane]

😔 👊

[summer stump]

The like a TMP_Text or a GameObject or a Canvas or something

Depends on what you want

[craggy bane]

yes tmp_text

so I added this

public void CompleteQuest()
{

Completed.SetActive(true); 

}

in the complete quest script

how do I make it popup after the quest tho it has an animation

[violet verge]

    }```

[slender nymph]

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

also consider using TryGetComponent instead of GetComponent immediately followed by a null check, TryGetComponent does both all in one line and also has the added benefit of not allocating garbage when a component isn't found in the editor

[ivory bobcat]

Do the bullets get destroyed?

[violet verge]

yea

yes when they hit the enemy they dissapear.

[slender nymph]

if there isn't any other code that destroys them, then the issue is that the objects they are hitting have the right tag but do not have an IDamage component

[violet verge]

public class EnemyAI : MonoBehaviour
{

    [Header("--------EnemyStats-------")]
    public float Speed;
    public int Health;

    [Header("-------Components-------")]
    public AudioSource EmoteSource, WeaponSource;

    private Transform playerTransform;

    // Start is called before the first frame update
    void Start()
    {
        GameObject player = GameObject.FindGameObjectWithTag("Player");
        if(player != null)
        {
            playerTransform = player.transform;
        }
    }

    // Update is called once per frame
    void Update()
    {
        if (playerTransform != null)
        {
            MoveTowardsPlayer();
        }
    }

    void MoveTowardsPlayer()
    {
        // Move towards the player's position
        transform.position = Vector2.MoveTowards(transform.position, playerTransform.position, Speed * Time.deltaTime);
    }

    public void TakeDamage(int damageAmount)
    {
        Health -= damageAmount;
        if (Health <= 0)
        {
            Destroy(gameObject);
        }
    }
}```

[slender nymph]

this does not implement IDamage

[violet verge]

ahh

[ivory bobcat]

are you planning on reloading the scene when the player dies, if not i would just disable the game object instead of destroying it

oh AI class

i would still disable

if your gonna be respawning them

[vernal bronze]

don't mean to be bothersome but how do I put in a class

i thought my paint shtick was pretty neat

[topaz gorge]

its a container really

needed to define between different scripts and such

[vernal bronze]

thank you so much 🙏

[queen adder]

You may get an error if the name doesn't match the file right

[topaz gorge]

indeed file name must match class name

you can have multiple classes in a script but no need to dive into that right now

[queen adder]

[slender nymph]

depends on the unity version

[topaz gorge]

Does different unity versions function different when it comes to naming in classes?

[queen adder]

I didn't know that

[topaz gorge]

neither i

oh endless hes saying some unity versions dont give the error

[summer stump]

2022 and newer do not require them to match

[topaz gorge]

REALLY??

[slender nymph]

still can only have a single MonoBehaviour in a file that will actually be able to be added via the add component menu. that requirement also only ever affected adding a component in the editor

well good luck. i won't be helping you any further since you don't want to get visual studio configured. and considering #854851968446365696 specifically says "[Don't] Give answers to users without an IDE configured*.⠀🠖 Get them to configure it first." you probably won't be getting help from any other regulars until you do so 🤷‍♂️

you've been given the guide and were instructed on what to try after completing the guide. if you're still having trouble with some part of that then you need to fucking say what it is.
i don't enjoy fishing, so i'm not going to go fishing to find out what you're having trouble with

I need help, it never calls Sprint()

it prints nothing in console

and trust me I am in play mode

[slender nymph]

are you sure you have an active instance of that component in the scene?

[somber herald]

yeah ive been editing it and getting output

but this one line wont output for some reason

[slender nymph]

there are only a couple reasons that Sprint would never be called, either you haven't saved your code, the component or its gameobject is not active, or you are receiving an error. your console does not appear to have any errors though so it's gonna be one of the first two

[somber herald]

so I put a print statement above the function

and it did work

i deleted the print statement and now it works

but it still won't execute the code inside the function even though I am pressing left shift

[somber herald]

also i closed and reopened the project and the gameobject was active idk why

[slender nymph]

you're calling it every frame. so for one frame it uses the sprintMultiplier and the next frame it will not

[somber herald]

ooooh

[slender nymph]

GetKeyDown is only true the first frame you press a key

You're probably wanting the 2d variant

Hi ! I'm looking for a way to call a function when the user press and hold 2 input for 2s.
I've found the "hold" system in the input action manager but i can't find a way to tell unity "Do this function when both of theses input action are triggered"

thank's !

[queen adder]

is this not the 2d variant?

[slender nymph]

no, see the link i posted

[queen adder]

ooooooohhhhhhhh i see what you mean

it worked immdiately smh

thank you!!!

[somber herald]

If I put a line of code with some calculations in Update, it should reach FixedUpdate fine right?

if I put like

  totalMaxVel = playerMaxVelocity + sprintVal;

in update, fixedUpdate will receive that value by the time it gets to it right?

[slender nymph]

as long as totalMaxVel is a class-level variable or property then it will be accessible in FixedUpdate. just keep in mind that on frames where FixedUpdate runs it happens before Update so you'd get last frame's result of that math, but for most things (like this) that shouldn't be a problem

[somber herald]

would it be better practice to just calculate this in fixedupdate too or should I just keep it in update?

[slender nymph]

if the only place you need the value is FixedUpdate then it can just be a local variable in FixedUpdate instead of a field

[somber herald]

I think I found a better way to do this whole thing anyways but will keep in mind while I keep writing ty

i'm getting this error

[verbal dome]

FixedUpdate runs before update

[somber herald]

https://paste.myst.rs/f9pa3zn0

[verbal dome]

If it runs at that frame at all

[somber herald]

I'm super confused cus I don't see sprintVal at all

[verbal dome]

Never seen that myself. Did you google it first?

[somber herald]

i think HotReload might be messing up my Unity or something's wrong with my editor orrr im missing something and im stupid

i thought MissingException was super vague and a common exception so i assumed it'd yield nothing

[slender nymph]

yeah that's 100% caused by hot reload not actually reloading the code

[verbal dome]

Ah. I have heard that HotReload can cause problems

[somber herald]

ironically i don't know how to disable it or fix it

[slender nymph]

exit play mode, make a change and save your code so unity recompiles it, then you should be able to use it just fine.
if for some reason that does not work, restart the editor

[somber herald]

I just restarted the editor but same issue

ill do it again though since i dont see the hot reload ui

oh yeah hot reload has a recompile button in case of stuff like this

ya works now ty!

[somber herald]

is using physics.raycast downward every frame bad for performance

should I find a better way

i'm trying to smartanimate a foot to know when its touching the ground

[slender nymph]

no, but you should use the profiler if you have performance concerns so you can address what is actually impacting performance

oh how do I get that?

How do I solve this Gradle Build Failed to make an android build? My project version is 2021.1.19f1

[slender nymph]

#📱┃mobile

[neon ivy]

public abstract class ScriptableSingleton<T> : ScriptableObject where T : ScriptableObject
{
    public static T Instance { get; protected set; }

    public abstract void SetInstance();
}

I would like SetInstance() to not be abstract but I can't find a way to do the usual Instance = this in the abstract class that gets inherited. (for a wild guess I tried Instance = T but that doesn't work) is there a way to do it or do I have to have SetInstance() be abstract and have the scriptable object inheriting this override it?

[slender nymph]

Instance = (T)this;

[neon ivy]

ah thanks

[bold nova]

Can someone explain the logic behind creating a staic instance? We create a static copy of the same class inside the class? Why cant we just make the class static?

[slender nymph]

it's part of the Singleton pattern
https://refactoring.guru/design-patterns/singleton

[neon ivy]

uhhh, that doesn't work

[slender nymph]

ah right, you want to constrain to ScriptableSingleton<T> not just ScriptableObject

for example, here is my singleton monobehavior implementation: https://github.com/boxfriend/Utils/blob/master/com.boxfriend.utils/Runtime/Utils/SingletonBehaviour.cs

[neon ivy]

oooh the where : ScriptableObject is wrong

thanks :D

I can't believe this actually works xD

[slender nymph]

i feel like a singleton SO is a bit cursed though. wouldn't a serialized reference to an SO asset not be a better option?

[neon ivy]

it would probably be better, I'm just learning stuff

[slender nymph]

also unless you are creating the instance at runtime, isn't there the possibility that the SO asset won't even be included in a build if you aren't referencing it by anything else that is included in it?

[eternal needle]

it is not a copy of the same class, it is simple a reference to the current single instance of the class. Think of how you reference a GameObject or a Transform. By having either as a field, you are not creating a copy, you are just referencing the existing one

[neon ivy]

I'm calling SetInstance from a script so something has a reference to it. it's mostly for me to create libraries of classes in scriptable objects, like a list of CharacterData in which I can look up an npc's ID and get their information. I'm sure there's a better way to do it but I enjoy having a scriptable object for this and didn't want to create a reference to the scriptable object whenever I want to get some data from it

It is usually best to debug.log the values you expect or attach a debugger and step through your code to see what is happening. Code seems fine ish to me.

OnCollisionEnter is a 3D method but this seems to be 2D. You need to use OnCollisionEnter2D instead

[proper flume]

Oh snap, okay. Thank you.

[proper flume]

What a G, that fixed it

[real dome]

yo yo guys sorry if this is like NOVICE and im butting in but euler and quaternion angles scare me... im trying to flip an object by making the y scale -1 when the object (which always rotates to follow the players cursor) surpasses the y axis into the 2nd and 3rd quadrants of the unit circle.
y scale is -1 between 90 and 270, and y scale is 1 all else
https://gdl.space/jogayiviku.cpp
the program however only registers between 0-90 as 1 and all else is -1, its probably a really simple fix but i cant figure it out for the life of me guys 😭

[verbal dome]

-90 angle could be represented as 270, which is why your if-statement probably fails

You could put zRotation into a -180...180 range with this: cs zRotation = Mathf.DeltaAngle(0, zRotation);

[real dome]

would i put that just below

float zRotation = rb.transform.localRotation.eulerAngles.z;

[verbal dome]

Yep

[real dome]

it WORKS

great HEAVENS thank you so very much i felt so stumped man

[verbal dome]

Next time, try to debug your values. You could do Debug.Log("Z rotation: " + zRotation) and you would notice that it never went into the negatives

[real dome]

i DEFINETELY should have done that

im not quite sure why i didnt as ive done that before like wth

i think i was over relying on the values the unity editor gave me

trying to make connections between the values during runtime and out

either way though im a silly clown 🤡

[real dome]

alrighty hol on so by my understanding THIS is to read the local rotation value of the object in the -180...180 range, rather than the 0...360 range unity usually uses despite what the editor says is that correct?

[verbal dome]

DeltaAngle finds the shortest angle from a to b
When the first parameter is 0, it effectively just clamps it to -180..180

[fickle plume]

@real dome no off-topic media, please

[verbal dome]

I don't think the inspector values always match the localEulerAngles (or localRotation.eulerAngles in this case, which is the same)

But yeah sounds like you got it right

[real dome]

OK i think ive got it

again thanks so much for helping me out and having the patience to explain it does make sense now

[verbal dome]

The thing is that multiple different euler angles can be used to represent the same rotation

No problem

[real dome]

as in like uhhh

30, 390, 750, etc?

[ivory bobcat]

It might be -180 to 180

I don't recall the exact numbers

[verbal dome]

@real dome That yeah, but there are worse examples where you switch up every axis and the rotation is the same

[real dome]

i think ill stick to single axis rotation for now

i reckon thats a problem for future me to tackle

[verbal dome]

Yeah you are in 2D so you don't need to worry about this that much

Okay I got one example, (90, 0, 0) is the same as (90, 90, 90) 😵‍💫

[real dome]

Why did I ever leave unity2D...

Wait uhhhhhh

Consider that I'm in a 3d environment

If I decided to add or subtract 180 to the x rotation for a smoother transition instead of y scale -1

Would there be collateral y rotation movement?

[verbal dome]

Don't think so, you can always try it out

The best way is to keep your angles in variables, instead of just storing in/reading from euler angles

[proper flume]

Unity is gaslighting me. Is there anything wrong with my script? My player won't jump, but the bool for isGrounded still gets tripped to false, and I see my debug message. https://gdl.space/wupirazocu.cs

[verbal dome]

You are overriding any previous velocity here: playerRb.velocity = (Vector2.right * horizontalInput * speed);

You can solve it by keeping the current Y velocity:cs playerRb.velocity = new Vector2(horizontalInput * speed, playerRb.velocity.y)

[proper flume]

UGH. That makes so much more sense, considering I would have needed to change direction midair too. You're a lifesaver. I am STRUGGLING over here lol.

[verbal dome]

Also make sure that this doesn't get called multiple times:cs Physics.gravity *= gravityModifier;
For example, if you load a new scene with a new player object

Gravity would keep being multiplied everytime

Oh, also use Physics2D.gravity or it won't effect your 2D objects

[proper flume]

Well, I'm not too worried about that. This is a one scene demo, and it's just supposed to be for the learn.unity lab. Also, using that new line of code says rb does not exist in this context (CS0103) I tried changing the rb to my playerRb.velocity instead and that said that it can't use my horizontalInput as a modifier with Vector2 because it's a float var.

[verbal dome]

Yeah, it should be playerRb not rb, I'm just used to typing rb

Not sure about the second error/issue tho...

Oh.

[languid spire]

playerRb.velocity.y

[verbal dome]

Yep, I edited

[proper flume]

Ahhhh. Okay. Well, I didn't get any errors, but the issue persists. No jump.

[verbal dome]

This might not fix the issue, but call HorizontalMovement() from FixedUpdate instead of Update

FixedUpdate is where you should do physics related stuff

[proper flume]

Huh. Well that didn't fix it, and now my cube is floating above the ground, rather than dropping to it.

[verbal dome]

Send updated code

[tribal minnow]

hey guys i need help with making a character sit on a chair, i already have the sitting animation i just need help making the character sit exactly on the chair.

[verbal dome]

You can modify animated transforms in LateUpdate

[proper flume]

https://gdl.space/sunijacoxa.cs

[verbal dome]

You changed the wrong thing

[tribal minnow]

what does that mean 😅

[verbal dome]

The playerRb.velocity.y stuff is for HorizontalMovement

Revert back and do that

[verbal dome]

Move the player to the chair.

Using transform.position and transform.rotation on either the root bone or the root transform

[proper flume]

OHHHHHHHHHHHHHHHHHHH. So, I wasn't able to call playerRb.velocity for my jump, because I forgot to make the horizontalInput a NEW vector. Gotcha, gotcha.

[tribal minnow]

and how do i make the characters sitting position exactly the height of the chair

[verbal dome]

Not really what I'm saying

[verbal dome]

You can make a object as a child of the chair. Get a reference to that object's transform when sitting, and use that transform's position and rotation for the player when sitting.

[verbal dome]

Revert to this code, call HorizontalMovement from FixedUpdate, and change this line:```cs
playerRb.velocity = (Vector2.right * horizontalInput * speed);

```cs
playerRb.velocity = new Vector2(horizontalInput * speed, playerRb.velocity.y)```

That should be all

[proper flume]

I don't know if I'm reciprocating that I understand right. Basically by using //playerRb.velocity in my HorizonalMovement() method, and not listing a new Vector2, it was causing problems with my Vector2 in my jump code.

[tribal minnow]

thank you

[proper flume]

Yeah, that's what I did. Still fixing the code to add HorizontalMovement to FixedUpdate and I'll give it a shot

WHEW. Problem solved lol. My lil buddy is jumping now. I appreciate your help.

hao can i Debug.log in unity dots?

in dots code, it seems "'Debug' does not contain a definition for 'Log'"

[eager elm]

Try UnityEngine.Debug.Log();

[shell herald]

i want the marked Instanciate code to only activate on a 70% probability, how do i do that?

[eager elm]

if (Random.Range(0f, 1f) < 0.7f)

[verbal dome]

Alternatively, Random.value

[slender nymph]

in this case you can just use Random.value instead of Random.Range

[shell herald]

thx

Why do I get transform child out of bonds error

Even when I want to execute this function when the transform child isnt null

[verbal dome]

Because one of the GetChild calls is trying to get a child that doesn't exist

Better to use serialized references instead of relying on stuff like hierarchy or naming

https://unity.huh.how/references/serialized-references

[bleak vale]

@verbal dome can u give me a normal answear instead of just sending me a link?

Like what should I change?

Its like u would ask your partner how do you look and he/she would send you a link to a fashion tutorial :/

[verbal dome]

No. Read.
https://unity.huh.how/references/serializing-component-references

Use fields with [SerializeReference] and assign them by dragging them in the inspector

[bleak vale]

I cant assign them in inspector because I reffere to a one of the clients not a single player AND col.transform.childCount > 0 is a better answear than sending a link

[shell herald]

i wanna see in realtime how a float value changes, can i simply do "Debug.log(floatparameter)" and display that in the console? or would that not work

[bleak vale]

U would know that if u would just check my code that I HAVE to refere diffrent way than using inspector if u would just open this link

that I send you

If u want to actually help ppl than try to help them instead of sending a link :/

[verbal dome]

I don't see a single serialized reference in that script.

Why are you acting so entitled?

[bleak vale]

Because I cant seralize reference

[verbal dome]

How does the script tell me that?

Anyway, maybe someone else will help you. I don't deal with entitled kids

[bleak vale]

Mate I just dont get why ppl here are sending links to documentations or tutorials or other websited that have SO MUCH text to read when answear is just a simple line of code

[verbal dome]

Welcome to programming. Get used to reading.

[bleak vale]

Yeah. Maybe someone else will help beacuse u are so grown up that u dont undestand a simple kid's question :/

[bleak vale]

I get used to beacuse there is not much ppl that actually want to help instead of showing their ego

col.transform.childCount > 0

That was the answear mate

[languid spire]

the 'simple' line of code you are missing is Debug.Log. You are doing lots of stuff there which we can know nothing about and yet you are checking nothing worthwhile

[bleak vale]

The lots of stuff is if (weaponHolder.GetChild(0).gameObject != null)
{
GameObject weapon = weaponHolder.GetChild(0).gameObject;
Destroy(weapon);
}

[verbal dome]

Doesn't help that you immediately start whining when I point you to learning resources

[bleak vale]

If its lots of stuff that u dont know nothing about that good luck for you

[bleak vale]

Yeah. Like i would ask for teaching me resources

"Dad, why grass is green?"

• "Here child, you have a thick book about genetics"

[languid spire]

No, the lots of stuff is

 Transform player = client.PlayerObject.transform;
 Transform holder = player.GetChild(1).GetChild(1);
 Transform weaponHolder = holder.GetChild(0);
 Transform structureHolder = holder.GetChild(1);
 Transform spellHolder = holder.GetChild(2);
 Transform potionHolder = holder.GetChild(3);

and as we know nothing about your hierarchy we and you cannot know what those result in

[bleak vale]

"Dad, but I asked just simple question"
"Stop whining kid"

[bleak vale]

No the stuff that I ask is
if (weaponHolder.GetChild(0).gameObject != null)
{
GameObject weapon = weaponHolder.GetChild(0).gameObject;
Destroy(weapon);
}

And exacly this if (weaponHolder.GetChild(0).gameObject != null)

See?

Simple line of code

Why I have if isnt null but I still get error when gameobject is null

That was my question

And if u want really to argue about that

One of ppl answeared me

With simple answear

That u big brains couldnt do

[verbal dome]

Your issue is fixed(?), you can stop now

[shell herald]

im encountering something i dont understand, its an enemy patrol script and its supposed to move the enemy between two points, but right now, when my enemy arrives at a point, it stops forever and i dont quite understand why

https://hastebin.com/share/anuxikenay.csharp

[verbal dome]

Changing >= to > and <= to < might do the trick

[polar acorn]

Do you know what that line of code means or did you just discover the magic incantation to make errors go away?

What have you learned that might prevent you from having to ask another question in the future?

[bleak vale]

That using if != null still refere to something that should exist so thats why I got an error wich was my qestion

[shell herald]

sadly no

[verbal dome]

Put a log in DirectionChange and see how it prints

Oh wait. cs if(enemy.position.x >= rightEdge.position.x)
I think this should be <=

You have >= in both
