Derived classes?

[formal hill]

Absolutely not no

[rich adder]

jesus h christ so why is it in your code?

[neon ivy]

not sure what u mean by that

[formal hill]

I got it from a youtube tutorial

[rich adder]

and the tutorial didnt explain what it is ?

[willow scroll]

Entity
  - WalkableEntity
    - Player
  - ClimableEntity

[shell matrix]

hello, i have this issues and idk how to fix it.

[formal hill]

Not really

[rich adder]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[formal hill]

Or I just didnt understand

[rich adder]

shitty tutorial then.

[polar acorn]

Something on that line is null but you're trying to do something with it anyway

[formal hill]

Yeah well I couldnt find a brackeys tut on it

[neon ivy]

that would still be a limit of 1 type per object no?

[rich adder]

brackys is just as shite

[willow scroll]

Right. You can have multiple types per entity if you make them interfaces: IWalkable, IClimbable

[rich adder]

https://unity.huh.how/references/singletons
okay read these and come back when you're done
https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[neon ivy]

I mean like, if I have a Unity terrain, and I want to walk on some parts and climb on others, or neither on some other parts of the object

[formal hill]

So I'm supposed to make a singleton

[neon ivy]

using tags or scripts as tags would result in the entire object only being 1 thing

[willow scroll]

I am not particularly familiar with terrain. If you want to differentiate them manually, not on runtime, you can create a script, which contains a Flags enum

[neon ivy]

the terrain is just an example

[willow scroll]

Use the suggested example if you spawn specific prefabs

[rich adder]

please read it carefully make sure you understand what it does first.
You don't want to be using a wrench without knowing what its for

[wet raptor]

Thanks for your help before, I have fixed that issue with the input system.

I have this error now. Within the function I have:
private void HandleMovement(){
Vector2 inputVector = gameInput.GetMovementVectorNormalised();

[formal hill]

The second one is a whole book

[polar acorn]

Seems gameInput is null

[rich adder]

a "whole book" is a blogpost length guy have you really no attention span to learn something you bout to use 70% of your time in Unity lol
having detailed explanations are a good thing these days

[wet raptor]

The character moves around somewhat ok though (although no animations play now). I dont think I understand why gameInput would be null.

[polar acorn]

Where do you assign a value to gameInput

[formal hill]

I don't have the attention span or the time to read all of that right now. I gotta go sleep sometimes yk

[rich adder]

spoiler alert you wont make any type of functional game if you dont take the time to invest in yourself 🫡 goodluck with it

[formal hill]

alright whatever

[wet raptor]

I have this at the top of my MoveController script
[SerializeField] private GameInput gameInput;

which I think calls from a function that looks like this in my GameInput script

public Vector2 GetMovementVectorNormalised(){
    Vector2 inputVector = playerInputActions.Player.Move.ReadValue<Vector2>();

    inputVector = inputVector.normalized;

    return inputVector;
}

PS, how do I format code on here to show it better?

[polar acorn]

Okay, so where do you assign a value to gameInput?

[wet raptor]

Sorry I am not sure I understand. I am really quite new to this.

[pulsar meteor]

i cant get my animations to work i can only do idle

[willow scroll]

We're fine with that. Just don't come whining about your issues, which appeared, because you had no intention on taking a reasonable advice

[polar acorn]

Where have you told this script which GameInput you want this variable to hold

[wet raptor]

I dont think I have. All I have is the code that I have put so far. I have this
[SerializeField] private GameInput gameInput;

And then in the function
Vector2 inputVector = gameInput.GetMovementVectorNormalised();

Where GetMovementVectorNormalised is returning an inputVector from my input actions.

[polar acorn]

So, which GameInput do you want that variable to hold?

[pulsar meteor]

i want to have basic animation i followed a turtorial but i can only get idle animation

[formal hill]

Alright so just because I don't have time to read a whole blogpost for one thing that there is most likely an easier way around I shouldn't ask for help? Very smart

[willow scroll]

You shouldn't ask for help if you want someone to fix your issue by fully writing the code for you

[wet raptor]

So I understood that GameInput is class with the methods Awake and GetMovementVectorNormalised.

I thought that by instantiating the class at the top of my BadgerMovementController script I would be doing this.
[SerializeField] private GameInput gameInput;

then I could use the method GetMovementVectorNormalised() which is from the gameInput instantiation of the class GameInput assigning the input sytem variables to inputVector

[polar acorn]

You didn't instantiate the class there

you made a variable that can hold a GameInput

you still need to tell it which one of those you want that variable to hold

[lilac moth]

Can somebody assist in figuring out proper collisions in unity 3d?

If I make a rotating object kinematic, the player cannot push the object (which is good), but the object doesnt collide properly with the player at higher speeds.

If I make the rotating object non kinematic, the object collision with the player works, but the object gets pushed. This occurs even if I up the mass.

All I want to do is have a rotating object that collides with the player at higher rotation speed (not a very high speed)

[formal hill]

I don't want someone to do everything for me. There is a reason to why this channel is called "code-BEGINNER"

[polar acorn]

Then read it later when you are willing to

[neon ivy]

what they mean is that the easy way isn't the way you learn, singletons are very useful and it's a good idea to understand how they work

[formal hill]

I will when I have time

[willow scroll]

It's expected that you are willing to learn yourself. Not "I don't have the attention span or the time to read all of that right now, so I'ma just give you my code and you go fix it for me"

[polar acorn]

Yes, that's fine. Not every bug needs to be solved right away. If you can't do it right now then get to it later

[wet raptor]

Sorry but which one of what? Which instantiation of class (that I assume I have not done yet).

[formal hill]

That isn't what I said or meant, but sure cus you know better

[polar acorn]

A class is just a blueprint. It doesn't actually exist until you create an instance of it. If that script is a MonoBehaviour, you'd instantiate it by adding it as a component to a GameObject

[wet raptor]

Yes, I think I understand now.

Thanks for that.

[willow scroll]

Well, yeah, I know how to use singletons

[formal hill]

Yeah you probably do, but that isn't what I was talking about dumbo

[wet raptor]

The field is literally the part in unity that you can drag and drop things into?

So when we SerializeField it is kind of like making it available to the engine?

[willow scroll]

No, drag & drop is only supported by specific types

[willow scroll]

Yes, SerializeField makes it "persistent"

[wet raptor]

Yes thanks, that is what I mean. Very helpful.

[polar acorn]

SerializeField lets you set it in the inspector by dragging in an object

[willow scroll]

This makes myString visible in the Inspector

[SerializeField] private string myString;

This does not show myString in the Inspector, but still keeps it persistent across the game sessions

[SerializeField, HideInInspector] private string myString;

This makes other serialized myRef references not affected by this one

[NonSerialized] public YourClass myRef;

[wet raptor]

Yes, thank you I think I do understand this part fairly well.

I dont think my issue is as simple as just instantiating (assuming this is indeed the right way to instantiate this class) in the start method with:
gameInput = GetComponent<GameInput>();

It does not fix my issue. And this also stops the movement I had previously.

[willow scroll]

Where is the original issue?

[wet raptor]

Well the error log says it's the line:
Vector2 inputVector = gameInput.GetMovementVectorNormalised();

[willow scroll]

Since gameInput is null?

[wet raptor]

With the null reference :/

[willow scroll]

Is the reference successfully assigned after getting the component?

[wet raptor]

How would I check for that? Debug.Log gameInput in my update method?

[willow scroll]

Debug it after the assignment

[wet raptor]

Ah, no it isnt. It's null.

[willow scroll]

What does it mean?

[wet raptor]

(assuming you ask this to see if I understand something?) I think I must have something wrong with the actual GameInput class.

[willow scroll]

What might be wrong with it?

[wet raptor]

The naming is all okay.

I see that in the inspector when the game starts the game input field goes to null.

[polar acorn]

Then you have code setting it to null, or the object you set it to gets destroyed

[willow scroll]

If it's null, then there is no GameInput component attached to the object

[wet raptor]

But am I not attaching the component here?

[willow scroll]

Is the GameInput script attached to the object you're trying to get it from?

[polar acorn]

You are assigning an object to the variable gameInput.

Do you change the value of gameInput in code anywhere?

[willow scroll]

GetComponent is gameObject.GetComponent, which gets the Component, attached to the MonoBehaviour's GameObject

You don't have to use it if you are already referencing it in the inspector. Just make sure that you don't change the variable anywhere else, as mentioned by digiholic above

Press Ctrl + F and type the field's name to find its references

[wet raptor]

It was not attached. Let me take a look.

If I attach the script to the Badger Object (Is it right to call the items in the hierarchy objects?) the error goes away. Still no movement though. But I might have something wrong in between my input and actually making the object move.

[willow scroll]

Then this should work without attaching the script to class, assuming the GetComponent line is removed

You might want to show the move logic too

[wet raptor]

okay so removing the GetComponent line means the Badger moves around, I get the same Null error though, which I dont understand. How can gameInput be null but I still can use the input to move the object.

My movement logic as so:

        Vector2 inputVector = gameInput.GetMovementVectorNormalised();

        Debug.Log(inputVector);

        Vector2 moveDirection = new Vector2(inputVector.x, inputVector.y);

        // Rotate input to match isometric view
        moveDirection = new Vector2(moveDirection.x - moveDirection.y, (moveDirection.x + moveDirection.y) / 2);


        // Move the badger
        rb.MovePosition(rb.position + moveDirection * moveSpeed * Time.fixedDeltaTime);

        // Move the badger 
        if (moveDirection != Vector2.zero)
        {
            lastNonZeroMoveDirection = moveDirection;
        }
    }```

The debug log shows values going to 1 etc when pressing wasd

[willow scroll]

Why does the "badger" move around?

[wet raptor]

The position of the rigidbody attached to it is being shifted by moveDirection at each frame?

[slender nymph]

if gameInput is throwing a NullReferenceException but this code is still working, that means you have more than one copy of the component in the scene where at least one of those copies does not have anything assigned to gameInput

[willow scroll]

Got it. First, check whether you only have a single instance of the script, as mentioned above

[wet raptor]

Only a single copy of the script GameInput. I have a GameInput in my hierarchy, but that should not be the problem right? You can have a script the same name as the item in the hierarchy.

[slender nymph]

not multiple copies of GameInput, multiple copies of whatever the component you showed the code for

because your gameInput variable is not assigned on one of those

[cosmic dagger]

Did you type the script name in the scene hierarchy to see if multiple GameObjects appear?

[slender nymph]

more specifically use t:ScriptName to search for the component

the t: part is important because it searches by that type, otherwise you'd be searching for gameobjects with that name

[wet raptor]

Yes, I think I had gameInput assigned to my animator script as well.

Ok. so deleting the BadgerMoveController script resulted in errors. Attaching it back fixed the issue... I have no idea how this has worked but it's further than it was.

This is hard... haha

I am okay with programming with Python, I think I get really confused at understanding the Unity interface.

[slender nymph]

it usually helps to say what the errors are. but have you actually checked the scene for multiple copies of this BadgerMoveController component like i've been saying to do?

[wet raptor]

Yes, as I said I thought that this one was attached to both the parent object and the animation controller script.

[slender nymph]

you said that about GameInput

[wet raptor]

Sorry yes you are right

my mistake

[slender nymph]

or did you mean that you had assigned your Animator object to the gameInput variable on another copy of the component? if that is the case, you are absolutely using the wrong type for your variable

there is almost never a need to use a variable of type GameObject. use the actual component type you want to access instead

then you'll almost never need to use GetComponent and you'll never be able to assign an object that doesn't have the desired component to the variable

[wet raptor]

Alright, cheers.

I need to do much more reading I think.

And more trial and error

[queen adder]

https://docs.unity3d.com/ScriptReference/Collision-collider.html
I didnt understood this property. Is it the first contact?
Or is it the Collision.thisCollider and the contacts returns the colliders that Collision.thisCollider collided with as Collision.otherCollider?

Oh i believe it is the otherCollider. Yep found it. I hate the way my VS is not showing the codes always!

[pulsar meteor]

how can i add movement plus animations has anybody a good turtorial i can only find bad ones

[steep rose]

well first i would recommend !learning before you dive into things like that

[rich adder]

put the points in an array and use Gizmos.DrawSphere see where they appearing

[hybrid tapir]

https://pastebin.com/BLbtKCeS
why isnt the collision doing anything?

[cosmic dagger]

it doesn't say anything about contacts. it says the collider that your GameObject hit; that's pretty explanatory. "Fetch the Collider of the GameObject you GameObject hits," . . .

[polar acorn]

Do you ever get the "just collided" message in the logs?

[hybrid tapir]

nope

i have is trigger on on all the walls i can crash into and on the plane

[polar acorn]

Well that would be your answer

You're checking for a collision

not a trigger interaction

[hybrid tapir]

oh

[hybrid tapir]

https://pastebin.com/baHjxJ7e
now it says both in the log, but doesnt reset any values

[polar acorn]

Does the player object have a CharacterController on it

[hybrid tapir]

yes

[polar acorn]

CharacterControllers do not like being teleported. You can either disable it, set the position, and re-enable it, or call Physics.SyncTransforms() after the teleport

[hybrid tapir]

alright ill try that

[polar acorn]

So does this have a CharacterController or a Rigidbody?

[hybrid tapir]

both

i gotta go to work now

[polar acorn]

Don't

You can't have both, you need to pick one or the other

[ripe vigil]

hat do i do

what

[polar acorn]

If you want to use Maya files, you need to have Maya installed

[ripe vigil]

how

[polar acorn]

how what

[ripe vigil]

what maya

and how do i instal it#

[polar acorn]

The same way you install basically any other program

[ripe vigil]

what

can u just tell me how plz

[polar acorn]

How did you install Unity?

You went to their website and downloaded it then ran it

So do that

[ripe vigil]

i got it on wish.com

its not called unity tho

its called unreal engin sounds bad

[polar acorn]

Ah nevermind it's another problem child wasting everyone's time

[ripe vigil]

also

it says to buy maya

is there a way to get it for free? @polar acorn

[rich adder]

discussing pirated software is against #📖┃code-of-conduct

[ripe vigil]

im not

im just asking if there is a way

to get this to work

cus its saying something about it not working

[rich adder]

if you need maya you install it, if you dont have it buy it or dont use files reliant on it

[ripe vigil]

how do i do that

i have a .mb file

[polar acorn]

instead of using maya files, don't

[ripe vigil]

can i use a obj

[rich adder]

then delete it

[ripe vigil]

ok

[rich adder]

or convert it

[ripe vigil]

done

[long jacinth]

My enemy isnt following me what could be the reasons for that? i baked my probuilder ground btw https://justpaste.it/9x96u

what do i do to fix this

[rich adder]

if you're just gonna plaster a bunch of stuff and expect anyone to help make a thread, spamming chat isn't going to get you help

[ripe vigil]

ok thx

[rich adder]

enable the gizmos and check whats happening in Scene view

[ripe vigil]

where can i start a thread

[rocky canyon]

here, its ez right click a message and Start Thread

[ripe vigil]

random things not working

[long jacinth]

its twitching

[rich adder]

where is the destination set

zoom out

[rocky canyon]

@rich adder did u fix ur gizmo/camera issu?

[rich adder]

haha naww never bothered i just chalked up as a bug

[rich adder]

this is in playmode ?

[long jacinth]

yes

[rich adder]

huh why is player floating

maybe enable these too so we can see more info

[long jacinth]

capsule collider and character controller are bigger than the GFX GameObject of the player

[rich adder]

prob have to select the navmesh agent by itself in playmode to see the path plotted on

[long jacinth]

how do i select it on its own

u mean i disable every component but that

[rich adder]

i mean just select the CircuitBug

[rich adder]

try moving agent.SetDestination line by itself In Start() and see if its working

[queen adder]

Thank you ✨ I did it to approve my thought after asking to some AI. It got so much power for giving direct answers now. It is so annoying to implement custom system for OnTriggerExit-Collision() that getting triggered whenever objects got disabled 🥺

[rich adder]

Ohh like OnTriggerExit still runs on disabled gameobjects ?

[queen adder]

Yes. After some researches, they didnt implemented this due to PhysX bullsht. But 2D senior developer told in one article: "I opt for OnDisableTriggerExit" so which was already what i was going to do.

With UnityEngine.Pooling system i was able to get the performance i need by not creating a list for every collision or trigger

[ripe vigil]

what to do about this thing

it keeps repeating

[slender nymph]

have you tried restarting the editor?

[ripe vigil]

its growing

[ripe vigil]

it worked

[queen adder]

i really cant figure out how to get my bullets to instantiate 90 degrees right

[slender nymph]

Instantiate requires a Quaternion for the rotation parameter, luckily you can use Quaternion.Euler to create one from euler angles

[queen adder]

i tried that and it did this

[slender nymph]

and you are certain that nothing else affects its rotation? there's no physics like a Rigidbody2D that can rotate it, or any code like assigning a parent that rotates? and that when you instantiate it with Quaternion.identity as the rotation it points exactly along an axis?

[queen adder]

yes, No rigid body, no code affecting rotation, and it is perfectly upright with quarentation.identity.

[rare basin]

your ide is not configured

and you typed quaternion instead of uppercase

[slender nymph]

that's still correct, it's just the quaternion struct from unity's Mathematics package

[rare basin]

ah

[slender nymph]

it has an implicit cast to UnityEngine.Quaternion so it's fine

[queen adder]

ive done everything the ide link told me to and it doesnt work i guess

[slender nymph]

it's configured

[queen adder]

oh okay

[slender nymph]

if it weren't then that red underline you showed with your first screenshot would not have appeared

but you should show the inspector for the instantiated object

ideally the hierarchy too

[queen adder]

the capital fixed it

it works now

amazing

[slender nymph]

ah, i see what the issue was now. Mathematics.quaternion uses radians in its Euler method

UnityEngine.Quaternion uses degrees

[queen adder]

would this work as intended? trying to make it so when the object collides with another specific object, it changes colour, and stays the default colour while not colliding with it

im quite sure that colliding = true wouldnt be applicable to everything else but i have no idea to make it like a global change

[wintry quarry]

You would need OnTriggerExit2D to detect the exit

Also you can just do else {

You don't need else if and a whole nother condition

[queen adder]

do i scrap the colliding variable or

[wintry quarry]

if (colliding) 
{
}
else {

}```

Also yeah you really don't need Update here

You can just change the color in OnTriggerEnter2D and Exit2D

There's no need to check every frame

[queen adder]

youve lost me i have no idea what to write here

[wintry quarry]

Just put the color change stuff directly in OnTriggerEnter2D

Instead of colliding = true

[queen adder]

i tried this exact thing before and it just took the else as like a final verdict

and kept it the same colour

like this?

[deft grail]

if the collided gameobject has tag Player it will change to that colour, if it doesnt have the Player tag then it will run the else statement

[queen adder]

didnt work

[deft grail]

what didnt work, did you place a Debug.Log to make sure the code runs

[bleak mist]

Anyone know how to make semi-colon get added automatically on save using C# with VScode?

[queen adder]

this isnt the outcome i wanted

i wanted it to change colour when touching the collider

and turn back to normal when not being touched

[deft grail]

#💻┃code-beginner message

[devout flower]

Debug the collider’s object’s tag in other (unless the enter code works)

[queen adder]

i have no idea what thats supposed to mean

what do i put there

[deft grail]

use OnTriggerExit2D to change the colour back to normal when you Stop colliding

[queen adder]

so i dont need the else

[deft grail]

no, doesnt even make sense

it just does if you collide with Player it does X otherwise it does Y

[queen adder]

well i was told to use else so dont look at me gulp

[slender nymph]

you also don't need the GameObject.Find if the Renderer you want to change is on this object (or the one colliding)

[deft grail]

no one told you to do else

you were told to use OnTriggerExit

[queen adder]

here

[deft grail]

thats just a tip to improve your code

instead of checking a whole else if

the main thing he said was use OnTriggerExit2D #💻┃code-beginner message

[queen adder]

like this?

[deft grail]

you need to check the tag in the OnTriggerExit2D also

unless you want it to just run if it exits any collision that it detects

[queen adder]

would doing the exact same code as the top bit even work

[deft grail]

why wouldnt it?

[queen adder]

i dunno it just looked like it wouldnt

[slender nymph]

another thing that needs to be pointed out is that your color constructor parameters are wrong. Color uses a float from 0 to 1

[queen adder]

i copy pasted it from a website i have no idea what else to use

[deft grail]

Color32, also thats why you shouldnt just copy paste

[slender nymph]

divide those values by 255f if you want to use a value from 0 to 1. otherwise use Color32

[queen adder]

i have

zero idea what youre saying this is why i copy pasted

seemed to work for me

it works

though the objects dont collide regularly

is there a fix for that

[deft grail]

are you moving with physics or not?

[slender nymph]

define "collide regularly"?

[queen adder]

the two objects ive been using dont collide

[slender nymph]

also keep in mind that trigger colliders are not solid

[queen adder]

ive got two colliders on my object

the regular circle collider for the actual object

and a second larger box collider as like a hitbox of sorts

the regular circle collider doesnt collide with the other object

[slender nymph]

trigger colliders are not solid

[queen adder]

the circle collider isnt a trigger

the box one is

is it because the box is like overlapping the circle maybe?

[slender nymph]

no, either the other object has a trigger collider on it or you are not moving in a physics friendly way

[deft grail]

answer this perhaps

[queen adder]

my movement script is pretty jank

[queen adder]

i erm. dont know how to

i dont know what you mean

[slender nymph]

how are you moving

[queen adder]

should i copy paste my movement script here

private float _speed = 5.0f;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    float horizontalInput = Input.GetAxis("Horizontal");
    float verticalInput = Input.GetAxis("Vertical");

    Vector3 direction = new Vector3(horizontalInput, verticalInput, 0);

    transform.Translate(direction * _speed * Time.deltaTime);
}

[deft grail]

thats not using physics

[slender nymph]

transform.Translate does not respect collisions

[queen adder]

got any other scripts i can use

[deft grail]

and idk what you mean by this, looks perfectly fine lol

[queen adder]

it weirds out on collision

smudges into the other object a little

and is all around kinda floaty

[slender nymph]

nobody is going to just hand you working code for free. consider going through some basic courses like the pathways on the unity !learn site to learn wtf you are doing instead of expecting to just copy/paste everything

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[deft grail]

no, just use a Rigidbody instead of the Transform, you have the Input code already written

just adapt your code instead of trying to copy paste more scripts that you dont understand

[queen adder]

i prefer to learn like this

[slender nymph]

then i won't help you. good luck.

[queen adder]

i always read the script through to understand it as much as i can before pasting it

dont just assume that i blindly shove whatever i find into there sob emoji sob emoji

[deft grail]

thats what most people do so its all we can expect

use either .AddForce or directly set the velocity .velocity with a Rigidbody, and it should be colliding fine

[queen adder]

can you walk me through what you uh.mean by that

i replace the transform.translate with those but how do i format those

is it just the exact same but transform.translate is replaced with .addforce?

[static wasp]

unity is being dumb again, do i restart it?
my code:
script 1:```cs
public static float player_health = 100;

script2:```cs
player_health -= 5;

error: ```
Assets\Scripts\Enemies.cs(43,13): error CS0103: The name 'player_health' does not exist in the current context

[strong wren]

script1.player_health

[static wasp]

oh, i forgot about that

thx

weird how it didn't tell me that there was a problem in vs code tho

[strong wren]

Your IDE is probably not properly configured

[static wasp]

it is, and it normall tells me when i have an error

[strong wren]

Both should catch this

[static wasp]

i think it's because i had vs code open for 13 days straight

lemme restart it

weird

it still doesn't tell me about errors

[queen adder]

@deft grail sorry for the ping, tried this but i get the "Object reference not set to reference of an object" error, not sure what to do

private float _speed = 5.0f;
private Rigidbody2D rb2D;

void Start()
{ 
    rb2D = gameObject.AddComponent<Rigidbody2D>();
}


// Update is called once per frame
void Update()
{
    float horizontalInput = Input.GetAxis("Horizontal");
    float verticalInput = Input.GetAxis("Vertical");

    Vector3 direction = new Vector3(horizontalInput, verticalInput, 0);

    rb2D.AddForce(direction * _speed * Time.deltaTime);
}

[static wasp]

i changed it to debug console and then back to problems and now it shows errors

weird vs code bug ig

[deft grail]

use GetComponent

and just add it yourself in the inspector

[queen adder]

where

[deft grail]

instead of gameObject.AddComponent

[queen adder]

would i have to make it public?

to add it in the inspector

[deft grail]

no?

[queen adder]

how am i meant to add it in the inspector if its private

theres nothing to add to

[deft grail]

i mean adding the component to your game object...

not assigning the variable

GetComponent will assign it

[queen adder]

uhmmI think im lost here

what do you mean by component,,

the script?

[deft grail]

bruh, the Rigidbody2D component

that you need to add to your GameObject

in the inspector

[queen adder]

i already have rigidbody2d on my object

[deft grail]

then why are you using AddComponent in your code?

[queen adder]

i dont get the error anymore but i cant move

[deft grail]

just use GetComponent and your set

[queen adder]

i was thinking that but i didnt know getcomponent was a thing

slash forgot

[deft grail]

dont multiply by Time.deltaTime

[queen adder]

so do i make it a vector2

and remove that

[deft grail]

🤔

[queen adder]

oh wait no

oops wrong bit sorry

[deft grail]

is this a top down game?

[queen adder]

more of an experiment probably wont become anything

[deft grail]

is the experiment a top down experiment

[queen adder]

yeah

still cant move

[deft grail]

try rb2D.velocity = direction * _speed;

[queen adder]

oh by the way is there a reason for most variables i see having a _ by the side

[deft grail]

its a preference, but thats mostly used for private variables i think

[queen adder]

still doesnt work

[deft grail]

should work im pretty sure

show the updated code and the inspector of your gameobject?

[queen adder]

private float _speed = 5.0f;
private Rigidbody2D rb2D;

void Start()
{ 
    rb2D = GetComponent<Rigidbody2D>();
}


// Update is called once per frame
void Update()
{
    float horizontalInput = Input.GetAxis("Horizontal");
    float verticalInput = Input.GetAxis("Vertical");

    Vector3 direction = new Vector3(horizontalInput, verticalInput, 0);

    rb2D.velocity = direction * _speed;
}```

[deft grail]

you froze the position...

freeze just the rotation

[queen adder]

wasnt an issue with the other script oopsie

ive forgotten quite a bit

[deft grail]

because it wasnt using the Rigidbody to move lol

[queen adder]

works fine now

thank you

[deft grail]

you are probably moving faster diagonally, if you wanna remove that you need to normalize the direction vector

[queen adder]

how do i do that

[deft grail]

.Normalize()

[queen adder]

where do i put that

[deft grail]

try it yourself, look at the docs, look at examples online

[queen adder]

did that actually

[deft grail]

so what did you try

[queen adder]

uhh wait i thought i had it

i tried Vector3.Normalize()

the example i saw said that

didnt work

[deft grail]

normalize the direction vector

[queen adder]

what does this mean

where do i put the normalize

ive tried in front of the vector and the direction

[deft grail]

😭

on your direction vector

you can do this on a new line if you wish

to not confuse yourself

[queen adder]

i dont know what you mean by that

do i make a new line like

direction.normalize()

and thats it

[deft grail]

try it and see

[queen adder]

i googled it but nothing i saw was referencing any actual examples

WOAH that fucked it up hard

what does normalize even do

[deft grail]

show what you did

[queen adder]

just what i wrote

direction.normalize()

[deft grail]

yes but show where you put it

[queen adder]

directly under the vector3

[deft grail]

screenshot it

[queen adder]

gaah effort

[deft grail]

whats wrong

[queen adder]

moves a seemingly random amount after i let go

[deft grail]

use GetAxisRaw to make it an instant 0-1
GetAxis gradually increases from 0-1 and 1-0

[mellow sorrel]

is it weird that C++ is easier for me than python

idk it just feels easier to pickup

[deft grail]

how is this related at all to this server or channel 😄

[mellow sorrel]

oh

😭

unity only forgor

[mellow sorrel]

wait bro it says #💻┃code-beginner

stupid

[mellow sorrel]

im kidding

oh mb

lol

[queen adder]

okay works well

not exactly sure wherte to go from here actually

[deft grail]

depends what you wanna do

add an enemy?

[queen adder]

im thinkingg

the entire point of that changing colour object

was to at a very basic level copy the tables from enter the gungeon

im assuming theres a way to like

swap objects

the colour change is to highlight that its in range to be used

and id press a button to swap the object into something else

[deft grail]

what does it do, flip over doesnt it?
you can just play an animation on the collision and add/change the properties of a Rigidbody2D to make it interactable

you can do pretty much anything in the collision

[queen adder]

iiiii wouldnt know where to start hold on

okay basic things can i change that colour swap into more of a

highlight

[deft grail]

just make each part in order

[queen adder]

like a glow around the borders

[deft grail]

think you need a shader or you can just make a sprite that has an outline

[queen adder]

i have no idea how to play animations or use the collision or change properties of a rigidbody2d

[deft grail]

its all pretty much the same
referenceToYourThing.DoSomething();

[queen adder]

thinking for the future id imagine changing the sprite into an identical one with just an outline would be like

i dunno it just sounds weird

is that what most people do?

[deft grail]

they use shaders or theres an Asset on the asset store im pretty sure

but its paid i think

the asset uses shaders, but you just dont have to make it yourself

[queen adder]

uhhhm ill just

make sprites

gaah somehow the new movement script fucked up the colour change script

[deft grail]

shouldnt change anything in terms of the collision

[queen adder]

it just doesnt change colours

gives me a weird error

[deft grail]

what error

[queen adder]

assertion failed on expression: go.isactive()

[teal viper]

Look at the stack trace. Where is it coming from?

[queen adder]

the huh

please keep in mind im an idiot

[slender nymph]

this stuff is why you should actually make an effort to learn from a structured course instead of trying to brute force your way through this by copy/pasting everything

[queen adder]

did you not read what i said

i dont just spam paste whatever i see

i read and look up whatever im looking at

to at least get some idea of what it means

listening to courses isnt for me it doesnt stick i like to do things from experience

[teal viper]

Then look up what a stack trace is.
Anyways, none of this would be a problem if you were to share the details of the error correctly(by taking a screenshot for example).

[queen adder]

it says nothing more than that and stacktrace

and id prefer to ask actual experts before blindly googling what might not even be important

how would i know stacktrace means anything

[teal viper]

Well, then look at the damn stack trace. You said you don't know what it is.

[queen adder]

how was i supposed to know its important before asking

[teal viper]

You definitely sound like you know what it is here.

[queen adder]

asking a question wont kill anyone

[teal viper]

Are you gonna actually provide the info or not?

[queen adder]

?? are you like insinuating i know more than i let on on a unity discord server

dlich can you like calm down im not hurting anyone

[steep rose]

stop fighting

[teal viper]

Ugh... Okay, I'm outta this one.

[radiant frigate]

https://gdl.space/imosuresos.cpp i am doing a pinball flipper and want it to rotate until a certain point(in this case either max rotation while holding down the D key or minRotation if viceversa) but it keeps just going until +5 or -5 in the z axis and doesnt rotate until the 25 or -15 am i missing something?

[queen adder]

this is what it says

[teal viper]

This is not the error details...

[queen adder]

this?

[teal viper]

Yes. You can see that it's your script causing it.
The rest you can investigate on your own. Learn what a stack trace is.

[queen adder]

looks way too complicated and i dont think its needed

looks like its an issue with my ontriggerexit

[rocky canyon]

yup, exactly

on line 35

[queen adder]

doesnt exactly say whats wrong with it

im at a bit of a loss

[radiant frigate]

im debugging and it indeed tells me that the transform.rotation.z value is higher than the maxRotation so the if conditional should be correct which should lead to rotating it by 1 degree each frame (which doesnt happen)

wait i used transform.rotation.y instead of .z

💀

[teal viper]

Didn't you say that you prefer to learn on the go? If so, you should be googling every single thing you don't understand and digging into documentation. If you can't do it, this is not a correct learning method for you and you should go over courses as suggested previously.

[queen adder]

it literally gives no information on the error

but i solved it anyway

only issue is i probably need a better way to change the colour of an object

[teal viper]

If there is no info on the error, then google the API you call on the line that throws the error. You're probably using it incorrectly

[queen adder]

i showed you everything that the error told me

[deft grail]

you can make 2 variables of Color and just assign the color in the inspector
so you can change it anytime without having to change the actual code too

[teal viper]

You didn't show the relevant code though.

[queen adder]

i need to do it within code

i didnt need to because ive solved the error

i think i know what it was anyway

the way i got the objevt was way too complicated i entirely forgot this script is only used on THE actual object

so i didnt need to find it

[teal viper]

Not gonna get very far if you keep that way of thinking.

[queen adder]

dlich can you hooooop oooooooff

what is your issue with me im only asking questions youre being a debbie downer

i need a better way of doing this

[deft grail]

like i said, make a variable

[queen adder]

i didnt exactly understand what you meant

can you like explain more pretty please

[marble hemlock]

kind of looking for an idea here
https://hastebin.com/share/bebarupaqe.csharp
https://hastebin.com/share/bulerapofi.csharp

how do i get it so that ItemHeld is sort of a spot to put new things in?

[queen adder]

sorry that sounds sarcastic

[deft grail]

make a variable of type Color and do = myColour; instead of new Color

[marble hemlock]

like the idea is "hey okay now that you clicked e on this thing the raycast hit, and it qualifies as something you can indeed pick up, put it in the ItemHeld slot in the inspector"

[teal viper]

Don't know if you solved it, but transform.rotation is a quaternion, not Euler angles. You should probably avoid using it's members directly.

[queen adder]

is myColour an actual unity code thing or would that be the variable name

[deft grail]

variable name

[radiant frigate]

yes im trying to use transform.rotate which i think fits better

[queen adder]

can you write out an example

[marble hemlock]

oh i feel like i put too much in the thing

[deft grail]

that is the example

[queen adder]

im not good at deciding what would be replaced

no like

[deft grail]

i told you what to replace

[marble hemlock]

okay just in general, how can i set it up where the object is intended to be removed and moved from the slot?

[deft grail]

what i would do is just myRenderer.color = myColour;
make variables for both the Renderer and the Color

and assign the variables in the Inspector

[queen adder]

im lost

[deft grail]

replace your line of code with this one... nothing complicated

as simple as it gets

[teal viper]

You don't need to raycast at the same thing twice. You can get the hit object from the raycasthit struct.

[teal viper]

There are no "slots" in unity by default. And the exact implementation would depend on your project needs/context.

[queen adder]

this cant be right gaah it isnt clicking

[deft grail]

wtf

[queen adder]

ooh type color

i didnt know that was a thing

[deft grail]

[SerializeField] private Color myColour; and assign it in the Inspector

[queen adder]

and for the renderer variable

what does serializefield do

and wouldnt private make it so i cant see it in the inspector

[deft grail]

allow you to assign a value in the inspector while the variable still being private

[queen adder]

oooooohh

fixes that issue

[marble hemlock]

thank you

it was giving me a message but i hadnt realized that was why

idk what to do though

not sure how id implement a field that is designed to have different things take its position

[queen adder]

says myRenderer doesnt have a definition for color

[deft grail]

what type is myRenderer...

[queen adder]

renderer

[deft grail]

show me

[deft grail]

do you have your own script named Renderer perhaps?

[queen adder]

nope

[deft grail]

oh wait, look at your other code

you dont access .color from the renderer

[queen adder]

didnt you tell me to do this

[deft grail]

yes, but its also just an example.
and you can see thats not what you did with your other code

ive never used a Renderer so i didnt notice

[queen adder]

so uhm

what do i do

[steep rose]

seems like your ide is not configured

[deft grail]

look at this

[steep rose]

from what im seeing

[deft grail]

looks configured to me

[queen adder]

fuck am i meant to be seeing,,,,,,,

[deft grail]

your code?

how you access .color

[queen adder]

.material?

do i include that

[steep rose]

Debug.Log() should be blue and yellow no? and shouldnt collision be blue?

[deft grail]

yes

[queen adder]

oh cool i actually figured it out

[steep rose]

as long as it is autocompleting you should be fine

[deft grail]

probably just IDE visual, it has red underline though

might just be missing Unity extension on VScode i think it is

[queen adder]

wait waitt

fatal flaw i think

i wanted to switch between the two colours

i have one option

do i change the original objects colour

[deft grail]

so how would you solve that 🤦‍♂️

[steep rose]

oh yeah it seems to be configured 😅

[deft grail]

you need 2, you have 1, i wonder what your supposed to do

[teal viper]

Wdym by that?

[queen adder]

do i need a second serializefield for renderer

not showing up in inspector

im gonna have to assume so the second colour isnt either

[deft grail]

yes, but for the Renderer you could just use GetComponent in the Start method

[queen adder]

so serializefield works for one variable only

[queen adder]

that seems a bit more complicated i wont lie

[deft grail]

literally 1 line of code, which also would be error proof

if you fail to assign it in the inspector, you will error

[queen adder]

yeah but thats a line of code that i dont know from heart

whereas i can just write what i already know

and not forget

error proof

[deft grail]

🤔 its 1 line of code

literally 3 words

[radiant frigate]

i managed to make it work

[queen adder]

i dont know getcomponent

[deft grail]

its self explanatory

[queen adder]

anyway its still signficantly easier to just copy paste serializefield

and add in the renderer

though probably not because the shit didnt work grin emoji

it turns invisible when i go up to it

[deft grail]

then your adding a GameObject that doesnt have a Renderer

[queen adder]

hold on

no i fixed it

they just default to transparent for some reason

yay now my little square turns a darker brown when i go up to it

joyous day

[deft grail]

you need to set the Alpha to 255 in the inspector

[queen adder]

yeah i did that

honestly i would much prefer the outline

isnt it paid?

[steep rose]

isnt what paid?

[queen adder]

shaders to outline an object

[deft grail]

brackeys has a video on it, 1st result.
you can try watching that

[steep rose]

you can just look up a tutorial for that

im not sure why it would be paid 🤔

[marble hemlock]

okay well its sort of like this:

[queen adder]

oh hes using something ive never seen before

i might be a while

[steep rose]

well the shader graph does that

[queen adder]

i have a better idea i think

can you switch sprites of a gameobject

[deft grail]

so thats like 90% of the things in the engine..

[queen adder]

i can just make another since its just a simple square

[queen adder]

#💻┃code-beginner

[deft grail]

yes, the same was as you do colour
just reference the SpriteRenderer

[queen adder]

id rather stay with the basics

[steep rose]

i would just learn how to use shader graph

and everything else

[marble hemlock]

1. Raycast hits object
2. Object has the pickup layer, so Unity returns a debug log telling you that it can be picked up.
3. Clicking E, will send the debug log that you picked up the object.

the problem is that I tried to set it up in a way where whatever object you clicked on would go into a public game object class called ItemHeld

[queen adder]

before i even know how to code

[steep rose]

then !learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[queen adder]

kinda what im doing right now

[marble hemlock]

my beloved....
https://learn.unity.com/project/beginner-gameplay-scripting

this is a great way to get started with learning programming in unity, and the videos are short and sweet with demonstrations

[steep rose]

you are doing this course?

[queen adder]

no

i haaaate courses

[marble hemlock]

no

[queen adder]

im learning my own way

[marble hemlock]

stop

no

listen

[queen adder]

i wont learn anything from a course

trust me

[steep rose]

what?

how

[marble hemlock]

you wont learn anything trying to follow along tutorials without knowing the basics

[queen adder]

it doesnt stick

i get so bored

[marble hemlock]

they're like 5 minute videos

[queen adder]

i dont like having information spat at me

[steep rose]

then coding shouldnt be for you

[queen adder]

i wanna do it myself

[marble hemlock]

all due respect, thats not going to work

[queen adder]

worked for python

[frosty hound]

@queen adder Can you stop flooding this channel.

Make a thread if you're going to thought dump

[queen adder]

oh my bad i tend to send more sentences at once than a single long one

[frosty hound]

You're also just talking nonsense. This isn't the place to spam questions just because you refuse to learn with the resources available.

[queen adder]

ive just been asking questions and applying them? i dont see the harm

its been helping me

[marble hemlock]

oh boy

kayla are you watching tutorials?

[frosty hound]

We don't do handholding here. If you're finding yourself asking questions for every little single beginner thing, use threads.

[queen adder]

i always forget those exist oopsie

[marble hemlock]

like when you want to do something, do you specifically look up a tutorial?
Like say you want to make a movement script, do you simply look up a movement script related to 2d or 3d unity?

[queen adder]

yeah

i look up things and also cross reference it with questions here

ill make a thread hold on

[teal viper]

Next time, keep it all in one message. I could easily miss this message.

What do you mean by a "public game object class"? Are you referring to a public field of type gameObject?

[marble hemlock]

ye
it keeps hitting me with a "there is no reference for itemHeld" and i'm just like
well yeah the reference is supposed to be constantly swapped out. when you're not holding something, its not supposed to have anything referenced because you arent holding anything

[queen adder]

stupid class for stupid people (kayla

[teal viper]

What is hitting you with "there is no reference for itemHeld" and is that the exact wording?

[marble hemlock]

well to be exact it says:
UnassignedReferenceException: The variable itemHeld of PickupScript has not been assigned.
You probably need to assign the itemHeld variable of the PickupScript script in the inspector.

[teal viper]

Okay. Share the script that has that field as well as where you assign it and try to access it.

[marble hemlock]

PickupScript:
https://hastebin.com/share/sofusiraca.csharp

PlayerInteract:
https://hastebin.com/share/umapicotik.csharp

something else broke and im going to try to fix that

okay idk why but the rigid body of one of my objects is no longer working 😮‍💨

fixed the other thing it had nothing to do with the rigidbody

nvm it broke again 👍

[teal viper]

Take a screenshot of the error details. Or share the script+line that the error is thrown at. Just share the whole error stack trace.

[marble hemlock]

the error isnt showing up in VS but on unity

and where it says the problem is

[ivory bobcat]

It says that you've forgotten to setup the reference from the inspector in the Unity Editor.

[marble hemlock]

this silly bit right here

[marble hemlock]

perhaps its best if i explain what im trying to do

[teal viper]

Yes. VS only would show compile errors. This is a runtime error. Untoggle "collapse", select one of the errors and take a screenshot again.

[marble hemlock]

i want it, upon clicking e, to say that the object it just collided with is now equal to itemHeld

i dont even know if im even on the right track

[teal viper]

By investigating the error, you could understand if you're on the right track or not.

[marble hemlock]

well i understand the error, and why its giving me the error

i didnt put anything into the itemHeld gameobject variable

should i just make an invisible object and that becomes the reference 🗿

[teal viper]

Great. So you either need to check if something is assigned to it, and avoid trying to access it if not, or avoid calling the method when you think that nothing is assigned.

[teal viper]

Probably not. That would imply that you're holding an invisible object. Is that what you want?

[marble hemlock]

i want it to stop complaining that there is no reference

i meant more like an empty parent object

but i want whatever is in the itemHeld slot to be replaceable by the another object if I click on it

and something completely unrelated broke this is rough

[teal viper]

Then start with dealing with this issue. How can you prevent it from complaining? What does it even mean if it's complaining?

[marble hemlock]

im gonna try again and take it apart

it cant be this complicated

im almost there

[teal viper]

Don't try again. Try understanding and fixing the issue first

Answering my questions might help with that.

[marble hemlock]

well if i put an empty parent object in there, it would stop asking for a reference object
its upset it doesnt have a reference because i'm telling that reference to become a child of another object
i tried slotting my flashlight into the slot and it works

sort of

it follows what the script is expecting itemHeld to do, but its still saying that there is no reference when i run the code

[teal viper]

Why not just avoid executing the logic if no reference is assigned?

Wouldn't you think that's the most natural way to prevent it from complaining?

[marble hemlock]

well by default you're not supposed to be holding anything, and when you click e, it'll pick it up

but i might be working backwards actually

[teal viper]

That doesn't answer any of my questions. Can you actually read my messages?

Let's start simpler. What does the error mean? What value would your variable need to have for this error to appear?

[marble hemlock]

i may not be understanding your questions

[teal viper]

Then ask for clarification. What part do you not understand?

[marble hemlock]

i dont know what you mean when you ask what the error means
its saying that there is no reference, which makes sense, because itemHeld is meant to be a GameObject

im gonna lay down for a bit until something loads in my head

[teal viper]

What does it mean that "there is no reference". What value does the variable have at that time?

[marble hemlock]

nothing

[teal viper]

No. There's no such thing as a variable that doesn't have a value in code.

What value does a reference type have by default?

Have you ever heard of null?

[marble hemlock]

gonna take a short break

maybe will be better if i clear my head

[static cedar]

Hi peps, wondering how am i gonna draw a grid?
Like this, just draw the lines infinitely. I just need some place to get some vague idea or tool how am i gonna achieve this.

[teal viper]

I'd recommend going over the C# basics, as it feels like you're missing some very basic understanding of the language.

[marble hemlock]

i think im doing it wrong

im going to try to create a flowchart of what im trying to do so i can better visualize what i want to interact with what

i might not even need 2 scripts for this

[teal viper]

You most definitely are. But a bigger problem is that you don't understand the basics. You're gonna keep on facing issues until you fix that.

[teal viper]

A custom shader probably.

[static cedar]

I first looked at mesh honestly.

But either way, i never tried em, so gonna have to learn em first.

[marble hemlock]

okay figured it out

sort of

i mean something else broke but sure

improvement

i told it to make itemHeld, whatever the game object hits (assuming you've clicked E), which then references the pickup event in the same script, that now has the information that itemHeld now has a value

and then after that, i go "well if itemHeld != null", then do the things

something completely unrelated broke but im making progress i suppose 👍

[hybrid tapir]

i just realized by charactercontroller you dont mean my own script i only have rigidbody

[hybrid tapir]

wait a darn minute

so
defaultValues = player.transform;
makes it update even though i put it in the START method?

[teal viper]

If you need an answer, you should provide a bit more info on what you're doing

[eternal needle]

from the single line of code i see, you're seemingly assigning a Transform to the defaultValues and probably printing out the position. Nothing about this has to do with Update, Transform is a reference type. itd be kinda weird if you stored a reference to a transform yet none of the values updated when you wanted the position

[hybrid tapir]

yes i guess ill have to do its values seperately to have the initial values

[versed zinc]

im making a 3D shooter game rn, working on interactions. I have my Interact() marked as override but it still gives me this error:

i told chat gpt to make me an bullet script but everytime i press click it dosent shoot pls anyone

and this is my bullet script
`using UnityEngine;

public void SetDirection(Vector2 direction)
{
    moveDirection = direction.normalized;

void Update()
{
    transform.Translate(moveDirection * speed * Time.deltaTime);
}

// Destroy the bullet after a certain time or when it goes off-screen

[snow warren]

hello

i need some serious help

[queen adder]

Hello!

[snow warren]

suppose i have a scroll rect

and i add some content into it at runtime

normally scroll rects do not align them automatically

what i want is to align the scroll rect automatically

with C#

how can i do that

my bad

i didnt know about the layout group

[ripe vigil]

can someone help me please im trying to get a animation to work but whenever i press whats suposed to do it nothing hapens

[vale marlin]

Also make sure to take a look at the "Content Size Fitter" (goes on the same GO as the layout group) to make sure the content sizes with the children

[snow warren]

ok thanks for the help

[idle ginkgo]

if i want to instantiate a particle effect before a box gets destroyed
how do i do it ?
like cuz after the object is destroyed the particle is also destroyed with it

[ripe vigil]

i need help im following a tutorial but for them the debug stops and for me it continues

this is my code

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

public class animatehandonimput : MonoBehaviour
{
public InputActionProperty pinchAnimationAction;

public Animator handAnimator;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
   float triggerValue = pinchAnimationAction.action.ReadValue<float>();
   handAnimator.SetFloat("Trigger", triggerValue) 




}

}

it just spam this

anyone know what to do?

[rustic maple]

i get this error when i try to do a certain action with E "ArgumentNullException: Value cannot be null.
Parameter name: source" this si my script: https://gdl.space/yogonumihi.cpp

i also tried "KeyButtonDown("pickup"), and then in unput manager make one with the name pickup but that didnt work either

[short hazel]

If the stack trace points to line 49, collectSound did not have a value (it was null). Which means you didn't drag-drop the Audio Source into the script's Inspector

[rustic maple]

oh wow i didnt know i HAD to already put the sound because i later wanted to add an other sound, but thank you so much it finally works!

[vestal adder]

if im understanding correctly you could have the box be a child

of the particle effect

[idle ginkgo]

problem fixed

[ripe vigil]

what the hell do i do

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

public class animatehandonimput : MonoBehaviour
{
public InputActionProperty pinchAnimationAction;

public Animator handAnimator;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
   float triggerValue = pinchAnimationAction.action.ReadValue<float>();
   handAnimator.SetFloat("Trigger", triggerValue) 




}

}

For starters, you read how to ask questions and share code: #854851968446365696

[atomic holly]

Hello,
I try to create a weapon system with classes. It works but I want to put some delay between the function can be recalled. I wanted to use coroutine but I can't do this with classes if I understand. How I can do it ?

public abstract class AttackBehavior
{
    public abstract void Attack();
}

public class BowAttackBehavior : AttackBehavior
{
    public override void Attack()
    {
        BowSystem.instance.ThrowArrow();
        //Wait 2 seconds after use this function
    }
}

[short hazel]

You can declare a "coroutine method" just fine, you'll have to start it from a class that derives from MonoBehaviour

[long jacinth]

im extremely sorry for the late response but no its still not working

[atomic holly]

I don't understand. the function SetAttackBehavior() works but the value of weaponcooldown is not transfered to the PlayerDamage script. Why ?

using UnityEngine;

[CreateAssetMenu(fileName = "New Weapon", menuName = "Inventory/Item/Weapon")]
public class Weapon : Item
{
    public int damage;
    public int reach;
    public int speed;
    public float weaponCooldown;

    //What function weapons we will use
    public weaponAttack attackType;
    public AttackBehavior attackBehavior;

    public enum weaponAttack
    {
        Bow,
        Sword,
        MagicBook,
        Sarbacane,
        Axe
    }

    private void OnEnable()
    {
        SetAttackBehavior();
        PlayerDamage.instance.weaponCooldown = weaponCooldown;
    }

[short hazel]

OnEnable for scriptable objects does not work in the same way as OnEnable for MonoBehaviour. It will get called when the SO is created, not when the game starts

[atomic holly]

Ahhhhh

Is there a way I can transfer the value of the SO to a monobehaviour when the game starts ?

[short hazel]

From the MonoBehaviour that uses the scriptable object, call OnEnable() (which you'll have to rename) from the MonoBehaviour's own Awake or OnEnable

[slate haven]

someone added me as a collaborator on git repo. Now I made a new branch and I want to upload updated Unity project folder/files on it. How do i add my updated repo folders and files into it?

[short hazel]

Change tracking is automatic in Git. Make sure you've checked out (ie. switched to) the branch which needs to contain the changes

[slate haven]

I am new to git, can you explain more precisely

[short hazel]

Are you using the command line, or some app to manage your local Git repository?

[slate haven]

gitbash and git desktop

[slate haven]

I cloned the repo to my local computer, now I checkout to the new branch.
Now what im thinking is copying the updated files to the local repo and replacing, once its replaced, I will commit changes

[short hazel]

Well usually you should clone before you make any changes, and then you make the changes in the clone directly. That will catch the changes automatically. But yes if you have another copy of the files elsewhere, you can replace them in the cloned repo and they'll be tracked by Git

[slate haven]

yeah before I downloaded the files, edited them. thatswhy

[long jacinth]

can someone pls help with this problem

[long jacinth]

navmesh is not moving

[teal viper]

Try not setting the destination every frame.

[long jacinth]

when do i set it

[teal viper]

When the target position changes

[long jacinth]

its always gonna be the player

[teal viper]

Then maybe wait a few frames between setting it again. Anyways, there's no guarantee that it's the cause, so just try for now.

[long jacinth]

do i put it in start?

[teal viper]

Try calling it once only at start

[long jacinth]

is it wrong that i baked the floor the player and the enemy?

[marble hemlock]

this might be an odd thing to try to code but is there a way to basically script:
if anything falls below a certain y level, force it back up to a specific Y level?

im not worried about the player, but just in that case too, i dont want anything falling
i dont know exactly how to have a script tell everything its not allowed to fall below a certain point. I feel like I'd have to individually put that in each object that could possibly fall

ig it wouldnt be too difficult using prefabs, but just for future reference it would be nice

im not sure how to handle clipping like this

[timber tide]

is this using rigid bodies or the character controller

[marble hemlock]

for the things i pick up?

or my character?

[timber tide]

could just disable the gravity honestly and set the y when you drop the item

the items specifically

[marble hemlock]

oh well the player is controlled by the character controller but all the objects i pick up have a rigid body.

[timber tide]

Right, well modifying physics using rigidbodies is a pain. What you can do though is turn off rigidbodies when the y is of a certain height and recorrect it. But, I'd probably just use character controllers in this case if you do want to modify them.

this way you can ignore setting gravity on the character controller when it is of the certain height

[marble hemlock]

rigid bodies are cruel indeed

i might take a break because something completely unrelated broke too
When i hover over the pillars, i get the interact prompt, but the flashlight and cube are labeled the same way (Which gives me a debug log signifying that i should be seeing the interact prompt), but it gives me no prompt.

time to eat breakfast

[ripe vigil]

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

anyone know whats wrong i put the code in hastebin

[rocky canyon]

if u move the picked up item via forces or rigidbody methods it'll interact w/ ur walls

ignore my millions of gizmos

[marble hemlock]

random question
is the block the cube is moving against also a rigid body?

i realized that i had set it to ignore collisions because i didnt want the player dragging everything along, (Which it does interact with the other object i try to pick up, which is... fine but i dont want them glitching objects through things because it got put in a weird spot), but i

[rocky canyon]

the pickup object is a rigidbody

my player is a CC

[marble hemlock]

maybe i should have the objects kinematic until they pick it up and its dropped? but then id have to have it know when it hits the ground to set it back to kinematic

to prevent them from dragging things i mean

[ripe vigil]

https://www.toptal.com/developers/hastebin

what to do

[marble hemlock]

wait this shouldnt even be a problem if i finish the inventory system

i cant escape it

[rocky canyon]

i still havent done that but i need to

• when the object is on the ground (can collide with it)
• when the object is picked up (ignore player collision only)
  for now i just have an offset forward of the player just big enough to not touch my player when im walking forward w/ the object

[rich adder]

Are you sure the script is running. Put log in start as well , did you remove the setDest and put it from update to start? Make sure you print log in start too

[ripe vigil]

do you have any idea whats wrong with my code

[rocky canyon]

um i havent even looked but i can.

[ripe vigil]

thx

[marble hemlock]

cant do nonconvex and rigidbody together

UNITY WHY

[ripe vigil]

im new to coding i got no ide what going on

[rocky canyon]

welll gripAnimationAction isnt assigned correctly most likely..

[marble hemlock]

YOU'RE SUPPOSED TO BE ON MY SIDE

[rocky canyon]

and ur code link didnt work

[ripe vigil]

oh i can try again

[rocky canyon]

make sure the end of it is jibberish..

../ahjeoud1283

[rocky canyon]

eh that works

dont do that all the time tho.. mobile guys cant even see that..

makes em download it to their phone first

[ripe vigil]

u talking to me?

[rocky canyon]

yessir u posted code did u not?

[ripe vigil]

yes

ok

[rocky canyon]

anyway.. yea same answer

[ripe vigil]

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

[rocky canyon]

look at how u spell the one in update

and how u spell the one at the top

really carefully..

[ripe vigil]

ohhhh

im dumb

[rocky canyon]

no worries.. happens

misspellings are the bane of us all

[rocky canyon]

and this is correct 👍 (how u post the code anyway)

[ripe vigil]

thx

Hello everyone, I'm trying to replicate the camera movements seen in the Windows 3D Viewer application. I've attached a video to show the behavior I'm aiming for. So far, I’ve only managed to get the 3D model to rotate horizontally on its own axis, but I can't achieve the desired camera movements or vertical motion without the model doing a full rotation. I’ve also attached a video and the code I’m using. When I try to add vertical movement, the model ends up twisting and moving erratically. The model's pivot is already centered. I would greatly appreciate any help or suggestions to resolve this issue. Thanks in advance!

Code: https://paste.ofcode.org/39m6K3XRztYBqRk4ruGJL24

[rich adder]

first I would use the bounds center as the point to rotate around otherwise different pivots will rotate the object wonky. On another point the MS 3d view looks like the opposite happens , camera rotates around the 3D object rather than 3D object itself rotating

also looking at your code, you should never multiply mouse inputs by Time.deltaTime.

[rocky canyon]

the pivot / origin is offset

[golden ermine]

I have this script thats on ingredient that will drop after killing enemy, player will pickup ingredient and when he goes to another scene it will add up to amount of ingredients he had with ingredients he collected in another scene but problem is for example I have ingredient called Rotten Egg and in inspector under string name I write "Rotten Egg" as it is put in inventory script but when I play the game and ingredient is being instantiated it will have "RottenEgg" in inspector which is incorrect. Can someone pls help. Here is code:

[rich adder]

so whats the value supposed to be

[toxic cloak]

hello is it normal for screentoworld point of mouse position to detect mouse in scene in playmode

[golden ermine]

Value should be Rotten Egg and I put it like that in prefab @rich adder

but when its spawns in scene it will say RottenEgg instead of Rotten Egg

[rich adder]

show the inspector

[rich adder]

both prefab and spawned one

[rich adder]

depends what you're doing. If its 3D a worldtoray for example can be better

[golden ermine]

prefab, btw Im gonna use Zombie Brain for now thats also ingredient

spawned in game

inspector

[rich adder]

show how you spawn it in code

[toxic cloak]

like in play mode if i m in the scene view and move the mouse then? should the game view be affected

[rich adder]

things are affected when you tell them they are affected, scene to world is not just to detects clicks, its just to transform the mouse screen position to world (its just a conversion ) it doesnt have any additional logic.. Think Fahrenheit to Celsius etc

[toxic cloak]

is there any function in unity to prevent the detection outside the game view

[rich adder]

where do you set ingredientName , the one on this script

[rich adder]

probably lock the mouse,
what do you mean prevent detection?
explain whats going on (the actual problem) rather than your attempted solution

[golden ermine]

yoo thanks that was problem, I forgot to change string name on zombie enemy

[toxic cloak]

yes locking the mouse how do i do that

[rich adder]

https://docs.unity3d.com/ScriptReference/Cursor.html
this class has the functions

[toxic cloak]

thank you random person

[topaz rain]

Hi!
I'm getting some weird behavior.
I have a reference to one script. I have serialized the variable and referenced it through the inspector.
How ever, when I access it I get a working reference and a null reference at the same time.

I mean, i get to communicate with the script but I get a null reference error at the same time.

Any idea about whats happening here?

[rich adder]

probably duplicate script with it unassigned. I would search the hierarchy like so t:yourclassname

[topaz rain]

I only have one GO with that component in my scene if thats what u mean

[slender nymph]

for clarification, they mean another copy of the component in the scene, not another copy of the script in your assets folder

[slender nymph]

you didn't use the t: to search by type so it's searching by name

[topaz rain]

Like this? (haven't done this before :_D)

[slender nymph]

and make sure to do the search at runtime when you see the Null logs in the console

[muted anvil]

yes, I finally I correct it, thank you for the mention <3

[muted anvil]

why?

[rich adder]

becasue mouse input is already framerate independent

[topaz rain]

Also, idk, im asking for a vars value, not for objects with the component, so even if there are other objects with the component, my var should be referencing the one I've linked throigh the inspector right?

[slender nymph]

mouse input is already framerate independent, and that's the purpose of the deltaTime multiplication. so by multiplying mouse input by deltaTime you end up with stuttery camera controls

[rich adder]

I think I see a whitespace beginning of name ? I wonder if that causes issues searching

[slender nymph]

show the stack trace for the log. but if there are other objects with that component in the scene then they would only be assigned if you have actually assigned something to that instance of the component

[rich adder]

also would pass this inside Debug.log

Debug.Log(musicManager, this)
(this lets you click the log and it should highlight the object)

[topaz rain]

it works either way

ok guys got it

is not the music manager which is duplicated

but the menu controller

ty so much

i was going crazy

[topaz rain]

im so dumb sometimes xd

[slender nymph]

for future reference, don't just print single values. print actual log statements that make the logs actually distinct

[rich adder]

happens to all of us 😛

[slender nymph]

like instead of Debug.Log(musicManager); you should instead do something like Debug.Log($"{name} has {musicManager} assigned as music manager");

[rich adder]

i always cram name in there somewhere

[topaz rain]

i know, I should, but i get so impatient when basic stuff doesn't work

thanks for your help friends ❤️

[fervent abyss]

does anybody know any UnityEvents alternatives that can serialize parameters in Inspector
