[fickle halo]

Hey can anyone help me figure out why using static Mathematics works but using static Units fails?

[fickle halo]

no one in the official csharp discord knows....

[slender sinew]

usually it gives you that error when it can't decide which type to use if there are multiple types with the same name. What does it do if you have your IDE try to resolve the error for you? (Not sure what the hotkey is in VSC)

[night mural]

Is the one that works actually resolving to the one you defined? Or maybe UnityEngine.Mathematics?

[fickle halo]

when I do the f12 goto definition it does go to my own defined Mathematics

and the code that uses it's Tau constant works.

[night mural]

does the code in Units also work? maybe just an IDE error?

[fickle halo]

changing the name to Unitts does not work either..

getting the error in both Cursor and VScode ides

[night mural]

what about am empty project with just these 3 files?

[fickle halo]

does work.

so it must be unity

cannot proceed with my project until I get this fixed

just wasting an afternoon for some stupid unity meta file bug

[dire flare]

Pls is any free texture download either from browser or asset store safe from copyright can I use it to publish my game

[eternal needle]

This is a coding channel

And why even crosspost that

[dire flare]

I know! I desperately want to known

Tell me if you know

[eternal needle]

#📖┃code-of-conduct crossposting is against the rules, and asking again despite being told this is a coding channel is just spam.

[dire flare]

Ohh thanks for telling me

[fickle halo]

can anyon eplease help?

[naive pawn]

do you get the same compiler error in unity?

also have you tried reloading the c# server?

[fickle halo]

yes I have

[quaint thicket]

I'm stupid and blind...

[naive pawn]

lol

[quaint thicket]

If my question isn't artist related, but code related, would I still go there?

[teal viper]

Does it actually throw an error in the unity console too?

[carmine sierra]

when making a game do people first make the different mechanics work before structuring the game, or start from the start screen and go from there?

[naive pawn]

definitely not from the start screen

usually you should start with the core part of the game, which depends on what kind of game you're making

[carmine sierra]

okay I think im on the right track then

[naive pawn]

perhaps the story, or designing mechanics

or even a specific system that everything would feed into

[carmine sierra]

how could I lock the movement of the cue around this red line?

so it can't move further or closer than that

currently it follows the mouse when holding mouse click, I was told clamp would work, but not sure how

[naive pawn]

lock it around the center instead of the ring

much simpler

[carmine sierra]

I did that

it has a pivot point

[naive pawn]

get the direction between the mouse and the center, normalize that vector and multiply it by the target distance, then rotate it accordingly (using that same vector)

since the end of the cue is the important part, have that be the pivot

[carmine sierra]

multiplying by target distance would make it rotate more no?

[carmine sierra]

I have the pivot at the ball itself though, so it always faces the ball

like in 8 ball pool

[naive pawn]

...the ball and the cue are the same sprite?

[carmine sierra]

no

this is 3d btw

[naive pawn]

ok, what do you mean by that then

[carmine sierra]

you said have the pivot point at the end of the cue

[naive pawn]

right, i was assuming 2d graphics

[carmine sierra]

that would mean it can freely rotate by the tip, and wouldn't be locked rotating around the cue ball

[naive pawn]

"pivot" is basically "origin"

[carmine sierra]

I want it rotating around the cue ball

[naive pawn]

those are unrelated

having the pivot of the cue on the tip would make setting the distance be between the ball and the cue tip, rather than between the ball and the middle of the cue

[carmine sierra]

fair

I did have the origin at the middle

[naive pawn]

it would not

multiplying a vector by a scalar just scales the vector

[carmine sierra]

hmm, I am rotating here by changing transform.forward

I will try it but i dont get the logic

[naive pawn]

rotating and moving would be 2 separate steps, that both use the direction vector

[naive pawn]

are you familiar with vector math in general?

[carmine sierra]

yeah

AB = b - a

[naive pawn]

i have no idea what you mean by that

[carmine sierra]

direction A to B is the same as subtracting position of a from b

[naive pawn]

ah, ok.

wow, no ray/overline really breaks that.

anyways, multiplying a vector by a scalar just multiplies each element by that scalar, right?

the ratios of each element are the same, ie it points in the same direction

just the length is different

[carmine sierra]

yh

so i wanna use that for the movement not the rotation

[naive pawn]

yeah

[carmine sierra]

I googled this but im not entirely sure. Do I need a rigidbody on an object which will hit another item, and make it move. The object itself does not need to act under physics, only user control

(by mouse)

[naive pawn]

rigidbodies are what handle physics

if it needs to collide with physics rules, it'll need a rigidbody

but you'll have to set position and rotation through the rigidbody instead of through the transform, since the rigidbody will manage the transform

[torn marlin]

yo i need a code correction can someone help

the goal is for the red block to track the player and only move in the x axis making sure that it falls down normally

[carmine sierra]

the vid is dragged out a bit but the point is that it rotates when the mouse moves around the middle, not around the ball

I used a raycast to capture the mouse's position, so not sure why it captures it only from the middle of the screen

[naive pawn]

ok what's the issue

[torn marlin]

nvm i got it

[naive pawn]

there's a few issues im seeing in that code

[torn marlin]

rb.velocity = new Vector2(direction.x * moveSpeed, rb.velocity.y); it was this line of code

[torn marlin]

hmm? like

[naive pawn]

the distance > 0 check is not reliable
floating points aren't exact, you'll want an epsilon there

[torn marlin]

the point is inside the player tho, the enemy has to collide with the player

[naive pawn]

you shouldn't set the rotation of the transform, since the rigidbody manages the transform itself, iirc? (though, why do you need to rotate it to begin with)

[naive pawn]

that doesn't matter

[naive pawn]

looks like it's getting the direction between the mouse and the middle of the screen instead of between the mouse and the ball

[torn marlin]

this enemy needs a direction for the projectile

so when it rotates, the projectile comes out of the other end

idk im an absolute beginner lmao

[carmine sierra]

This line?
dir = new Vector3(ray.GetPoint(enter).x, 0, ray.GetPoint(enter).z);

[naive pawn]

ok, now think about when you add art
now the enemy has a top and bottom
the top and bottom shouldn't switch when it turns around, right?

[naive pawn]

if the origin is in the center of the screen, yeah that would get the direction to the center of the screen

[naive pawn]

remember this?

[carmine sierra]

yeah

[torn marlin]

you do have a point

[naive pawn]

you need to subtract the ball position at the beginning, then add it back at the end, to use the ball as the origin for that calculation

[torn marlin]

https://youtube.com/clip/UgkxGUNzDoSqe_bN6l9XAjMZdtBnVEMl_XZV?si=FpA2ApUjl9sb5Yg2

i just looked at the rotation thing he was doing and it was working

soooo i stuck with it

if anything at the end of the day i can just revert its scale to y = -1

[carmine sierra]

I subtracted the pivot points' x and z coords, which works. Although im confused why adding them didnt work

I assume its something to do with perspective

[naive pawn]

no that's unrelated

[naive pawn]

@carmine sierra

adding them did work. it put the cue around the ball

but you need to subtract at the start to get the calculation around the ball as well

[carmine sierra]

was confused what you meant by this

[naive pawn]

if you subtract the ball position from the ball position, what do you get

[naive pawn]

ah, right, i was thinking about the wrong axis lmao

[carmine sierra]

zero

[naive pawn]

yeah rotation like that should work fine

so nvm

rotating the z axis would turn it upside down

[naive pawn]

and that's the origin, right?

think about stuff that's centered around the ball
subtracting the ball position would make the stuff centered around the origin

now direction stuff, which is inherently based on an origin, works correctly

the direction from a to b, is the position of b, in reference to a
so by subtracting the position of a, you get the direction from (b - a) to the origin, not offset by anything

[carmine sierra]

sorry I gotta understand how the ray.getpoint works first

cause I thought it would find the mouse's position

on the plane

[naive pawn]

it does, but in world space

not relative to the ball

[carmine sierra]

i get what you mean but dont at the same time

[naive pawn]

the world has an origin

[carmine sierra]

yeah

[naive pawn]

everything is based on that origin

including the raycast

but the calculation you have needs a different origin

[carmine sierra]

which is around the pivot point

[naive pawn]

subtracting the ball position from everything involved (the ball, the mouse) gets the ball as a new origin
then you can do everything in that new reference frame
adding the ball position back puts it all back in the reference frame of the world

[carmine sierra]

ohhh ok

hmm but if we want to move the origin to the pivot, that could be a vector O->P (P for pivot). So wouldnt that be pivot.transform.position - origin

ray.GetPoint(enter) is at the origin?

[naive pawn]

origin is 0

[naive pawn]

no, it's wherever you clicked

[carmine sierra]

hmm so ray.GetPoint(enter) - pivot.transform would be a vector which goes from the pivot to the mouse's position

that's what I want

okay I get it now

thanks 🙏

How can i reference a script instead of a GameObject that has the script, so that all logic operated in a different script applies to every GameObject by itself instead of just the gameobject i referenced?

All of the cards have the same script and i want them to work independently

[naive pawn]

why not have the script on the cards handle that

[slender nymph]

show the CameraInteract script, you likely need to change logic in that to interact with any kind of interactable instead of only with a specific object

[tulip nimbus]

I believed that making everything that is interactable managed by the camera is simpler as it shoots the raycast

[tulip nimbus]

public class CameraInteract : MonoBehaviour
{

    bool selected;
    bool clicked;
    public InteractableCard card;


    void Start()
    {

    }

    

    private void Update()
    {
        if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out RaycastHit Hit))
        {
            //Hovering
            if (Hit.collider.tag == "Interactable" && clicked == false)
            {

                selected = true;

            }
            else
            {
                selected = false;
            }

            //DESELECTION
            if ((Hit.collider.tag != "Interactable" && Input.GetKeyDown(KeyCode.Mouse0)) && clicked == true)

            {
                clicked = false;

            }

            //Selects and states
            if (selected == true)
            {

                card.OnSelect();
            }
            else if (!selected && clicked == false)
            {
                card.IdleState();
            }
            if (selected == true && Input.GetKeyDown(KeyCode.Mouse0))
            {
                clicked = true;
                card.OnClicked();

            }
        }
    }
}

Excuse my bad coding, im still working on my structure

[slender nymph]

instead of using a field to refer to the card, use TryGetComponent on the object hit by your raycast. that will also eliminate the need to check the object's tag (which you are doing incorrectly anyway, you should be using CompareTag when checking an object's tag)

[naive pawn]

right, but then the camera shouldn't have to know what it's looking for, otherwise you'd be shooting out a raycast for each type of iteractable
why not shoot a single raycast, then check if it's interactable?
and then the script on the object can define how to interact

[tulip nimbus]

this is a great Idea! Thank you

[weary crystal]

Chat what is this

[slender nymph]

not a code question, and did you read it?

[weary crystal]

Oh where can I ask questions related to this and yes I read it but I don't really understand

[slender nymph]

#🔎┃find-a-channel

[weary crystal]

Alright thanks

[languid spire]

then say that rather than 'what is this'. The answer to your question, as asked is, it's a warning message

[weary crystal]

I mean like why am I getting this and how can I fix this warning-

[steep rose]

read it and it tells you

also it is not an error

[languid spire]

that is exactly what the message is telling you

[weary crystal]

Like it's saying migrate existing api to a the new api how can I migrate?

[slender nymph]

have you written a scriptable render pass? i'm going to go ahead and guess the answer is "no" considering the absolute lack of substance that your questions have contained. so you need to change the setting that the warning indicates so that whatever asset you've downloaded that includes that render pass will work

[weary crystal]

I do understand it telling me to disable the compatibility mode but, it's after the migration, how can I migrate though?

[steep rose]

Migrate existing ScriptableRenderPasses to the new RenderAPI
https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@17.0/manual/render-graph-system.html
and
https://docs.unity3d.com/6000.0/Documentation/Manual/urp/render-graph-introduction.html

[slender nymph]

have you actually rewritten your scriptable render pass features to use the render graph?

[steep rose]

ScriptableRenderPasses will still work, but in newer versions of unity it will be deprecated

[weary crystal]

No, I don't even know what that is. I just downloaded some assets and I guess it's probably from there.

[slender nymph]

because if the answer is no, and you have no idea wtf a scriptable render pass is, then you need to use the compatibility mode for that asset to work

[weary crystal]

I'll check this thank you.

[weary crystal]

Okay, I understand now, thanks.

[carmine sierra]

Are 4k textures overkill

[slender nymph]

this is a code channel

[carmine sierra]

where do i ask that

[slender nymph]

#🔎┃find-a-channel

and maybe also be more descriptive than just "are they overkill"

[carmine sierra]

would they slow the game down

would they take long to load

well it depends on the use case, also this is more of a question for #🔀┃art-asset-workflow

oh alr

[inland dirge]

Guys I’m new at unity programming I was just wondering why do we use for a variable [SeriatizeField] if we can use directly public ?

[slender nymph]

it's better to not make everything public, you wouldn't want just any object to be able to modify the state of your script just because you're too lazy to make a variable private. if there is no reason that another object should have access to a variable or other member then it should not be public

[inland dirge]

Cuz if we put it in private we can’t access the variable from another GameObject script ?

[languid spire]

correct

[inland dirge]

Okay ty

[languid spire]

fyi, if you want to be able to read but not write from another script, look into Properties

[steep rose]

[SerializedField] on a private variable will make the private variable show itself in the inspector

you can do the opposite for public variables to hide them in the inspector if needed [HideInInspector]

[inland dirge]

I think this is a bit more useful

[steep rose]

no

[inland dirge]

Why ?

[steep rose]

if you do not need to access the variables in other scripts

you should not bandage them

[slender nymph]

do note that HideInInspector does not do the opposite of SerializeField, the field is still serialized, just not drawn to the inspector. NonSerialized would be the opposite

[inland dirge]

But if you want to access the variable from another script and u don’t want it to appear in your inspector it’s great ?

[steep rose]

oops my bad

[steep rose]

yes only if you want to access it from another script and do not want it in the inspector use that

[slender nymph]

at that point just use a Property. in fact, according to the official c# coding conventions you should be using properties for any variable that needs to be accessed by other objects

public fields should typically be avoided whenever possible in favor of public properties

[inland dirge]

And also is OOP important in unity ?

[slender nymph]

yes . . .

[inland dirge]

Im cooked

[slender nymph]

how could object oriented programming not be important in an object oriented programming language

[languid spire]

OOP is important in anything to do with C#

[inland dirge]

My bad I’m coming from python idk much about it

[steep rose]

you should learn some C# then
https://dotnet.microsoft.com/en-us/learn/csharp

and learn some unity

Hi All, I'm working through the Programmer Pathway on UnityLearn, I'm currently at the stage of adding RigidBody to objects after adding in a small script but when I start the game, the vehicle collides with the crate, flies over it and then veers off the road 🙄 This is completely different to how the video presents where it pushes the crate out the way. Any ideas what I might be doing wrong please or is this just something wrong with this bit of the tutorial?

This is the section of the tutorial: https://learn.unity.com/tutorial/1-2-move-the-vehicle-with-your-first-line-of-c#639946f2edbc2a2fc462dd11

I have the same parameters as the video and there's only one script against the vehicle that includes as per the tutorial:

    // Move the vehicle forward.
    transform.Translate(Vector3.forward * Time.deltaTime * 20);

Vehicle mass: 1000, 0 drag, 0.05 angular drag with Gravity turned on and discrete collision detection.
Crate mass: 20, 0 drag, 0.05 angular drag with Gravity turned on and discrete collision detection. 😕

[rich adder]

you can try locking the rigidbody on vehicle although doubt thats done in the lesson. Always found it cringe they make it move rigidbody with Translate

[cosmic dagger]

Why are they using Translate to move a rigidbody? That makes no sense . . .

[rich adder]

yea fr

its been like this for a few years now..

[white prism]

Definitely an improvement, cheers! Not mentioned so far in the tutorial but I presume this is just where you set it to freeze position for the X and Y Axis under Constraints? or is there another way to do it?

Doesn't go flying and off the road anymore, doesn't throw the crates out as dramatic as the video but it's workable now 👍

[rich adder]

yes the constraint is usually how you make rigidbody not be affected by external forces/rigidbodies in specific axis

[white prism]

Got it, Thank you! 🥳

[sterile radish]

how do i make a gameobject access the sprite of its child?

[timber tide]

https://docs.unity3d.com/ScriptReference/Component.GetComponentInChildren.html

Easier answer, just bind that reference in the inspector

[queen adder]

For movement do yall usually use Input Maps or just if(Input.GetKey(KeyCode.YOUR_KEY));

[timber tide]

Input class is now considered legacy, but I still use it

[queen adder]

Alr

won't stop me

[queen adder]

For me it’s easier and whatever can make my experience easier to create I’ll use it.

[past spindle]

I want to set up my damage dealt to player based on distance from source of damage, but I'm not sure how to get the distance between 2 objects while accounting for negative vectors. I was gonna set up a local float and subtract the two vectors but it occurred to me that would return negatives, depending on the position of the objects. Is there a symbol or something I can use to convert the difference between two vectors into a positive?

[languid spire]

Vector3.Distance will just give you a positive distance

[naive pawn]

for future reference, what you're describing is the absolute value, available through Mathf.Abs

[past spindle]

thank you, and thank you for the name of it. I knew there was a name but I couldn't remember what it was called

If -- subtracts 1 from a variable, how do I subtract more than that?

[languid spire]

-= number to subtract.
This is really very basic knowledge you should have

[past spindle]

I got confused when they were explaining it in the tutorials. I've only been working with Unity for a few weeks

so += would just add the numbers then?

[languid spire]

then maybe you should do some basic C# courses

[past spindle]

I am

[languid spire]

yes

[past spindle]

I'm working on one of the last projects of the junior programming course through Unity Learn

[languid spire]

better to look here
https://dotnet.microsoft.com/en-us/learn/csharp
for basic C# knowledge

[naive pawn]

x •= y is shorthand for x = x • y for arithmetic and bitwise operators

[thorny basalt]

That also goes for /= for division, -= for subtraction, and %= for modulation

[past spindle]

I appreciate the notes

[naive pawn]

yes that's why i said arithmetic operators

[thorny basalt]

I know. I just wanted to give the specifics.

[eternal needle]

Dont think modulation is the word you want, modulus is the math term but in c# % is actually called the remainder operator

[naive pawn]

it's pretty much the same thing. it's not called the modulo operator because modulo isn't an operator, it's more of a context

[eternal needle]

They are not the same thing, the result can be different in cases

[naive pawn]

there's no "result" with modular arithmetic

[eternal needle]

Yes there is

[earnest iron]

How do u set up an enemy AI NPC?

[naive pawn]

in code 5 % 2 == 1, 5 != 1 % 2
in math 5 ≡ 1 (mod 2), 1 ≡ 5 (mod 2), 5 ≡ 3 (mod 2)

[earnest iron]

What? @naive pawn

[naive pawn]

not directed at you, sorry

[eternal needle]

You'll have to be more specific as to what you want, this isnt possible to answer just as is. Look up tutorials if you have absolutely no clue where to start

[naive pawn]

to clarify: there's no "result" from "mod" in modular arithmetic, it's not an operator

[earnest iron]

Pathfinder is what I mean. It's terrible

The character just disappears randomly

And sometimes it flies in the sky.

It should not do that

I have set up an area for detection of the player, but it doesn't follow the player.

Also my grammar is bad so don't judge me

[naive pawn]

tf you mean your grammar is perfect

[earnest iron]

My words might be confusing

[eternal needle]

What you've shown is like first year uni examples. I know how mod math works. Look up any docs related to it in computing and try to find something that isnt an operator.

[naive pawn]

in computing
did you miss the part i said i was talking about math

[earnest iron]

Do u guys know this

How can I fix it

[naive pawn]

im literally talking about "mod" in pure modular arithmetic being different from the "mod" in computing

[eternal needle]

Then you're talking about something completely different from my point above. My initial point was saying c# is the remainder operator, where it will give different results from modulus, ex: negative numbers

[naive pawn]

you brought up "the math term", so i assumed you were talking about, yknow, math

[eternal needle]

Look at the #854851968446365696 on what to include when asking. Also no one knows what kind of AI you want so this isnt really possible to answer

[eternal needle]

That was just because they said modulation, which isnt the correct term. Not sure how else I couldve phrased that

[naive pawn]

fair.

Ok

[languid spire]

you are not going to build very much if you do not learn how to search for information

[rich adder]

depends what you want to do and how the workflow suites you

[carmine sierra]

is slider not a component

[rich adder]

are you sure you are requesting the Slider from the UnityEngine.UI ?

[carmine sierra]

I called the slider object as a gameobject

[rich adder]

wut ?

[south juniper]

I think unity has mich more developer friendly tools. It's way easy to learn unity over other ar tools

well then there you go, you just aswered your own question

i didnt know you meant the using thing

the 'namespace'

[naive pawn]

it's probably just ide lag, given the misaligned error highlights

[rich adder]

namespaces are like "categories" in which Classes are bundled inside

[carmine sierra]

yeah, thats what UnityEngine.UI is right

[rich adder]

yes its a namespace

[carmine sierra]

also why can't I use SerializeField for sliders but I can for gameobjects

[rich adder]

the using at the tops are just shortcuts so you don't have to keep preceding the class with its namespace

[carmine sierra]

yeah

[naive pawn]

those 2 things are unrelated

[rich adder]

who says you can't

[naive pawn]

but maybe you had issues because you were using the wrong slider before

[carmine sierra]

there's different slider types?

[naive pawn]

no, you were just using the wrong definition

[rich adder]

yes ofc there are

UnityEngine.UIElements is the UIToolkit

[carmine sierra]

oh so there's different sliders depending on whether its uielements or ui

which do i want then

[wooden sky]

hello im trying to make a ribbon for a spear that uses DistanceJoints2D for animating it, but im running into issue where it spreads apart too much, any idea why?

using UnityEngine;

public class ProceduralRibbon : MonoBehaviour
{
    public GameObject mainPoint;
    public GameObject ribbonSegmentPrefab;
    public int segmentCount = 10;
    public float segmentSpacing = 0.5f;
    public float segmentGravity = 1f;
    public float maxSegmentDistance = 1.0f;

    private List<Rigidbody2D> ribbonSegments;

    void Start()
    {
        InitRibbon();
    }

    public void InitRibbon()
    {
        ribbonSegments = new List<Rigidbody2D>();

        for (int i = 0; i < segmentCount; i++)
        {
            GameObject segment = Instantiate(ribbonSegmentPrefab, transform.position - new Vector3(i * segmentSpacing, 0, 0), Quaternion.identity);
            Rigidbody2D rb = segment.GetComponent<Rigidbody2D>();
            ribbonSegments.Add(rb);

            DistanceJoint2D joint = segment.AddComponent<DistanceJoint2D>();


            if (i > 0)
            {
                joint.connectedBody = ribbonSegments[i - 1];
            }
            else if (i == 0)
            {
                joint.connectedBody = mainPoint.GetComponent<Rigidbody2D>();
            }
            joint.autoConfigureDistance = false;
            joint.distance = segmentSpacing;
            joint.maxDistanceOnly = true;
        }
    }

}

[rich adder]

told you, the UnityEngine.UI one

thats the Unity UI Package

not UIToolkit (the newer UI) which has no inspector components , just uses an external XML like structure or c# but you can't serialize it

nothing you should worry about for now though

[carmine sierra]

oh ok

I managed to reference the slider now, but Slider.value isn't valid?

[rich adder]

wdym not valid ?

[carmine sierra]

'Cannot access non-static property in a static context'

[naive pawn]

what's the code now

[rich adder]

are you not using the instance of the slider.

[naive pawn]

why would you do that though

[rich adder]

well i guess you're not

[naive pawn]

you were getting the slider just fine here

why did you remove the part that was correct

[rich adder]

just make a reference in the inspector as you did with the GameObject

and then use the instance

[SerializeField] Slider mySlider

[carmine sierra]

cause I was initialising a gameobject and THEN getting the slider, getting the slider directly is quicker

[naive pawn]

ok so you need to get the slider

not the type of slider

[rich adder]

but you're not getting the Slider, you're getting the definition of a class.. Just a blueprint.

you need the **Instance **

the Specific Slider created, the one on the gameobject

[carmine sierra]

oh, but with rigidbody components you can just reference a rigidbody without getting the component right?

If I remember right (havent done this in a few months)

[naive pawn]

you can but you shouldn't

[rich adder]

how's that related ?

[carmine sierra]

So type Slider isnt the same as the component

[carmine sierra]

both components im referencing

[rich adder]

Anything on a gameobject is a component mate

[carmine sierra]

exactly

[rich adder]

but those are the instances you need to reference

[carmine sierra]

so why does it work with rbs but not sliders

[naive pawn]

because rbs are old

and you shouldn't use that field anyways

[rich adder]

unity has fumbled MB properties

[naive pawn]

you should just GetComponent like any other component

[gray coral]

why i cant reach my camera script to activate

[carmine sierra]

alr

[naive pawn]

you're gonna need to elaborate

[rich adder]

"reach"? wdym

[gray coral]

        if (Input.GetKeyDown(KeyCode.Space) && !isMovingUp)
        {
            isMovingUp = true; // Start moving up

            // Activate the camera movement when jumping
            if (cameraController != null)
            {
                cameraController.ActivateCamera();
            }
        }```

i try to activate the script on the camera

[rich adder]

so whats wrong?

[naive pawn]

have you tried debugging at all?

[rich adder]

Debug.Log inside ActivateCamera and so on

[carmine sierra]

I realised the name was just incorrect, I didnt need to do getcomponent, so now im more confused as to why you said i should do getcomponent

[rich adder]

You don't need GetComponent if you have references already linked in the inspector

[naive pawn]

you would do GetComponent if you had a GameObject to start, like you did originally

[carmine sierra]

yeah

[rich adder]

always Get a specific component when possible, you almost never need to use GameObject field

[carmine sierra]

thats what I did

[rich adder]

yes, just saying in the future

[carmine sierra]

you said that what I had before was correct though, which was using the gameobject then referencing the component

[rich adder]

if you need a gameobject without specific component , I usually do it as Transform

[carmine sierra]

why?

[rich adder]

because its more likely you will use the trasnform than gameobject

any component can access its container gameobject / transform anyway

[carmine sierra]

genuinely idk what happened her

only other reference

[rich adder]

[naive pawn]

why do you need that SerializeField anyways
why not just make it public

[rich adder]

making everything public by default is bad design

[naive pawn]

it's probably just ide lag, given the misaligned error highlights

[carmine sierra]

public sounds dodgy like i could accidentally reference it

idk if im stupid though

[naive pawn]

for unity fields specifically?

[rich adder]

accidentally changed
n yea you should always make thing privates

[carmine sierra]

yeah it worked

[rich adder]

for any fields in a class..

[naive pawn]

no, i mean, even for unity fields specifically?

[carmine sierra]

intelliJ is bad for unity or smth?

[rich adder]

I never use public fields, if something else needs access, I make a property

[carmine sierra]

never had ide lag on vscode

[rich adder]

yes. You should be using VS or Rider

[carmine sierra]

yh i mean rider

Im using that

by same guys as intelli

[naive pawn]

i use publics specifically for stuff that goes through unity, i do use properties for access between classes

[rich adder]

wdym "through unity"

[naive pawn]

serialized fields, messages, lifecycle methods

[rich adder]

why make everything public thats on MB ? thats just bad design imo

[carmine sierra]

so serializefield is a good idea right? when I just need to locally change an integer easily through the inspector for example

[carmine sierra]

me? Idk what mb is

[naive pawn]

i don't, i use public specifically for the stuff i want to show up in the editor

[rich adder]

yes yes, just keep in mind Public does put it in the inspector too, SerializeField just makes it so its visible in inspector but not changable from other scripts

[rich adder]

thats silly lol
Thats literally what SerializeField does for privates

[naive pawn]

yeah i don't really like it tbh

[rich adder]

I'm not even gonna bother asking why, thats nonsense

[naive pawn]

not in concept, just feels unnecessary when you can just use a much smaller token

[rich adder]

smaller token? ?

[naive pawn]

idk i can't really explain it. nobody gave me a convention so i developed my own and now im just more comfortable with my convention i guess lmao

[rich adder]

my brain hurts

[naive pawn]

to me, SerializeField on a private feels like doing private to hide then SerializeField again to reshow it

can't explain it

[rich adder]

to show it only for the inspector..

[naive pawn]

yeah i get that

[rich adder]

but other classes dont accidentally touch any fields in that class

[naive pawn]

yeah i just don't do that

[rich adder]

thats what props and methods are for

i mean to each their own, just saying its bad design and not typical of C#

[naive pawn]

i was never shown typical C# lmao

[rich adder]

encapsulation should be one of your first lessons then lol

[naive pawn]

oh i know it well, i used to do java

[rich adder]

well then why would you break all of that in C#
its literally the same language (almost)

[naive pawn]

all the unity c# tutorials use public, i found out about SerializeField much later

[rich adder]

yeah cause they're shite tutorials

[naive pawn]

...literally all on the unity learn page

[rich adder]

its honestly not a big deal if its just you on the project anyway, but its bad design and you should always encapsulate even just to protect yourself from your future self

[rich adder]

that doesn't mean its good

Unity != C# standards

[naive pawn]

...weren't you the one defending it to me a year ago

"public" to me means accessible outside the "package" (from java), and unity is outside the package, so i use it for stuff that goes to unity

[rich adder]

in what regard? cause I do heavily criticize Unity and their inconsistency

public means anything else can change your score even though its not meant to be public SET etc.

why would you open yourself up to the possibility of accidentally changing something that you shouldn't change

[cosmic quail]

its a thing because then you or your coworkers wont accidentally use that public variable from other classes. otherwise why not make literally everything public then?

[naive pawn]

because i don't want to see random stuff about state in the inspector?

[cosmic quail]

what state? serializefield private is same as public for the inspector isnt it?

[naive pawn]

i found the convo, it was much shorter than i remember, so nvm i guess lol

[naive pawn]

i know what it means lol

[rich adder]

orly ? I'd love to see it 😛

[naive pawn]

you're assuming this preference is rational

[naive pawn]

this is the only reason for it

it doesn't make sense lol. but im already used to it

[rich adder]

at least your self aware of it which what makes it strange willing to choose it over just privatizing it

[naive pawn]

im very much not used to attributes

[rich adder]

its not that much work putting an attribute instead of public

[naive pawn]

even less so attributes that have effects rather than just validators (like Min or Range)

[naive pawn]

it is when you have a ton of muscle memory for the latter already

[rocky canyon]

imo, you'll learn/use them when u need em

[rich adder]

well hey, when you accidentally change the wrong fields later down the line.. You know why 😅 you do you though

[naive pawn]

(for access modifiers, not public specifically. java's default access level isn't private)

[rocky canyon]

what is it then?

[naive pawn]

package-private, aka internal in c#

[rocky canyon]

i hate java lol

[rich adder]

yeah internal can be accessed from within the same assembly

not comparible to private

[rocky canyon]

@rich adder u use many assemblies?

in ur current projects

[naive pawn]

yeah i still have no idea what you mean by this.
i know how encapsulation works, i just don't use it for inspector fields

[rich adder]

nah only used them a few times when i needed to compartmentalize everything

it makes a chore using assembly definitions tbh

[carmine sierra]

If I wanna detect if the mouse is down on a slider, should I give the gameobject a button component? or is there a way using the slider

[rocky canyon]

they both are exposed in the editor.. only difference is one is public (accessable from any class within that assemb) ooor private.. (only th class that contains it)

[rich adder]

its good if you're making an asset though but might confuse your users

[rocky canyon]

there dozens of ways

[naive pawn]

...are you trying to make the slider work yourself?
it already has drag and hover/click colors built-in

[rocky canyon]

not really a need for it to be a button unless thats the way u wanna do it

ya, i make my own sliders

i think unitys sliders are gross

[rich adder]

wdyn "down on a slider"

[naive pawn]

https://mdn.io/mousedown

[rich adder]

oh slider has OnChanged event you can listenn to

[rocky canyon]

damn, that link sends u thru the entire internet to get to the landing page

affiliation much?

lol

[rich adder]

you can however get OnPointerDown for example by using Ipointer interface

or event Trigger component

[naive pawn]

no it's through a browser's search iirc

[rocky canyon]

ya, duckduckgo

i seen it flash in my browser for a second

[carmine sierra]

as long as they know if the mouse is down on it or up thats all i need from now

[carmine sierra]

but how do I access those states

[rocky canyon]

its the setup/ margins/ and all that i dont like

[naive pawn]

https ://justlink.to/mdn/mousedown redirects to mdn directly but not really used to typing it

[rocky canyon]

u need to redo the entire slider to make it work like i feel it should

[rich adder]

https://docs.unity3d.com/Packages/com.unity.ugui@3.0/manual/SupportedEvents.html

[naive pawn]

do you need to?

[carmine sierra]

yes, yk 8 ball pool, how the slider snaps back after firing

I need to detect when the mouse releases

[naive pawn]

now my question is, should you be using a slider for that lmao

[rich adder]

look at the events I sent you

[naive pawn]

eh i guess that makes sense

[carmine sierra]

The script I want to detect the mouse's state on the slider, is not on the slider

it's on the cue control script

on the cue

so i couldn't use the pointer method could I?

[naive pawn]

you could have the slider be a child of the cue

[carmine sierra]

doesnt make sense in the game

[naive pawn]

why wouldn't it

[rich adder]

no its needs to be on the slider gameobject
but you can use an EventTrigger component instead of script

[carmine sierra]

weird layout in the hierarchy

[naive pawn]

having the controls for the cue, within the cue?

[carmine sierra]

true, but its UI

I can child UI in a gameobject?

[rich adder]

i think they want to use the Slider to give "power" to the cue

[carmine sierra]

yeah

[naive pawn]

yeah, just needs a canvas and then have the slider in the that canvas

[carmine sierra]

ohh right, forgot about those

[rich adder]

why not just use the OnValueChanged ?

[rocky canyon]

thats how i do it when i do use sliders

oh nvm i lied..

mine update w/ Update()

[carmine sierra]

cause the value changes while the player is choosing the fire power

[rich adder]

yea? isn't that what you want so you know how much force to apply?

[rocky canyon]

if theres visuals u may need to update during the drag tho

[rich adder]

or are you gonna launch after the slider was released? this is tricky

[rocky canyon]

and then when release set ur final value

[carmine sierra]

yeah, its not tricky dw, the event trigger makes it work as intended

[rocky canyon]

not too hard

it could be totally seperate

[carmine sierra]

youve played 8 ball pool right

just that control

[rocky canyon]

when mouse release (check on what happened w/ the slider)

no need to use weird hover crap on teh slider

[rich adder]

yeah but everyone does it different lol I never used a slider on mine but the Cue itself as the "slider"
further from ball = smack the ball harder lol

[rocky canyon]

who hasnt played 8ball? (Pool, Billiards, Etc)

to me if ur making a pool game sliders dont even make sense to me

i'd track mouse positions

click -> get position
release -> get position

then do the math.. get the direction/distance etc

[naive pawn]

oh god, does golf count as a cue sport

[rocky canyon]

use mins and max to calculate power

u dont hit golf balls w/ cue sticks

but its similar lol

[carmine sierra]

Yeah that makes sense. I was doing that initially but I think 8 ball pool's mechanism allows for way more accuracy (even without the ez guidelines)

[naive pawn]

they are pretty similar, was thinking if you could bend the definitions but i don't think so

[rocky canyon]

the power meter click/drag mechanic is the same

same as pool, angry birds, etc

[rich adder]

many pool games lets choose the power but there is another view usually for applying specific spin

[rocky canyon]

let me ask a question since we're on the topic..
if ur making a power meter w/ one u prefer(or is more fun)
click and have the power meter ping pong from 0 - max until u release
or
click and have the power meter go to max and then back to min.. and if u miss the click u get min power?

[rocky canyon]

one is more forgiving ofc

[rocky canyon]

i used to be a pool shark >8)

small town bs nothing to do

lol

[carmine sierra]

yh 8 ball pool has that too

[rich adder]

first one

[rocky canyon]

spin is called english btw

"putting english on the ball"

[rich adder]

me too minus the small town thing hehe i'm in the city of rats.. i mean nyc

[rocky canyon]

ohh dear

[carmine sierra]

I live in London and pool is still up there for fun things to do

[rocky canyon]

i thought yall played snooker or something

[naive pawn]

isnt that a specific type of spin?

[rocky canyon]

i thought it was all types of spin

i'll have to check hang on

yea its all spins

SIDE spins i guess

[carmine sierra]

I was just talking ab this yesterday. I thought snooker/pool were the same thing. Snooker is a diff game they just use red balls and one pink

no one plays snooker

casually

[rocky canyon]

snooker is like pinball + pool

[carmine sierra]

side spin seems impossible

like doesnt that mess up the whole aim if you flop it

[rocky canyon]

nah. its pretty easy once u play a bit

[rocky canyon]

well thats the point

get good lol

[carmine sierra]

top spin is ez

[rocky canyon]

using top / bottom spin causes alot of ppl to launch the cue ball off the table

lmao

[carmine sierra]

random question what floor could look better than this

[wintry quarry]

Not a code related question

[carmine sierra]

true

[naive pawn]

make it darker

[rich adder]

use a texture, also pool tables are cloth and not really that reflective

but yeah this should go in #💻┃unity-talk at most

[carmine sierra]

good idea

After I release firing, I need the cue to hit the ball and apply a force. Is the best way to do this to be applying a force to the cue and let it hit the ball that way

[rich adder]

this is entirely up to you, and some can workout better than the other..

relying on unity physics has its pros and cons

[naive pawn]

maybe if the masses are the same and it's an elastic collision?

but idk if you can guarantee that

if it's inelastic, the cue would follow the ball a bit after the impact, unless you specifically stop it

[rocky canyon]

have fun trying to replicate pool physics 😮

lol

[naive pawn]

maybe you can do that by setting the materials appropriately, but if not, you could apply an impulse force on the ball when the cue hits it

[rocky canyon]

im thinkin you'll def have to manipulate the ball a bit urself

[rich adder]

yes i usually nudge these types of physics with Reflect, the bounce material can help a bit but its unreliable

[frozen star]

I am building somewhat of a studio application in Unity for windows.
Users will be able to import large files. (audio, images, and video) and the game needs to persist them.
Users will be reading and writing to the folder that stores these files often.
Can I use Application.persistentDataPath ? Or is there a better directory?

[rich adder]

sure, or use assetbundle/addressables

[carmine sierra]

So i tried the addforce method, but to get enough force in to move the balls as intended, the cue seems to move so fast that it clips through the cue ball

should I just do the annoying thing of downscaling the mass

or is there a better method

[rich adder]

which collision mode did you put

try Continuous Dynamic

[carmine sierra]

It worked O_O but how

[rich adder]

https://docs.unity3d.com/ScriptReference/CollisionDetectionMode.ContinuousDynamic.html
do note this is probably the most expensive computations out of all the modes

if you can get away with it pick continuous only , but dynamic helps if both bodies move pretty fast

[carmine sierra]

considering its just one hit movement it should be fine

[carmine sierra]

whats the other body?

the thing it hits?

[rich adder]

might be overkill here , might be able to just get away with the regular continuous

[carmine sierra]

so both should be continouous

[rich adder]

ball is rigidbody no? cue is rigidbody no ?

[carmine sierra]

it worked with just the cue being continouous

[rich adder]

mhm continuous should be okay since they're not moving so fast

but it does exactly what it says, thats why those are generally more expensive but its okay in such smal usecases

[carmine sierra]

only dynamic works

[carmine sierra]

so discrete is like fixedupdate and continouous update

[rich adder]

no its just doing many "sweeps" as oppose to estimations

[carmine sierra]

estimations?

what does it estimate

[rich adder]

yes like based on how fast this thing is moving will it hit this thing

[steep rose]

discrete uses the discrete algorithm to check for collisions and check on the physics steps so for fast and quick collisions it might fail
https://docs.unity3d.com/6000.0/Documentation/Manual/discrete-collision-detection.html

also keep in mind there is a limit of speed for when collisions will just never not be wonky

like a max cap of speed, but you should theoretically never go that fast with a pool ball

[swift sedge]

and if it's too fast, then the other option is raycasting between where the object was and where it is now

[steep rose]

yes, it may be more expensive to do to so, so this is why people fake speed with effects

like speed lines if that makes sense or FOV changes

[timber tide]

rigidbodies should really handle a lot of clipping itself assuming you use forces

but it's far from 100% proof. I do think my own interpolation via character controller is better ;)

One thing though that we don't really think about is objects traveling at quick speeds at an intersection. Rigidbodies will actually try to account for that

[swift sedge]

what, like a car intersection?

[cosmic quail]

continuous rigidbody can fail and go through walls too

[timber tide]

Right, you can't easily raycast forward in that situation

[visual rune]

I have a small problem where in my script it is not recognising the PlayerController class? Any ideas?

[swift sedge]

you can calculate the new direction

but then that would be even more computationally expensive

[timber tide]

It probably some some calculations for intersecting some shape casts in those scenarios, but it only will detect others via continuous

[visual rune]

Does anyone know why..

[timber tide]

You've posted nothing and we can't read your mind.

[charred spoke]

What do you mean not recognising?

[wintry quarry]

Did youi create a class with that name?

[naive pawn]

classes should be in PascalCase

[rich adder]

where did you create this playerController

[naive pawn]

your original message says it was PascalCase

so have you tried referencing it using PascalCase

[visual rune]

Yes

[rich adder]

capitalization matters

[wintry quarry]

prove it

[wintry quarry]

also when you have a red squiggle it means there's an error

[visual rune]

Is PlayerController not a built in class

[wintry quarry]

you need to read the error message

[rich adder]

show where you defined this class

[naive pawn]

it is not

[wintry quarry]

of course not

[naive pawn]

are you confusing it with CharacterController?

[quaint thicket]

I'm trying to make a GameObject transparent at changing the GameObjects color alpha, but it's not working.

I'm using a basic Sphere.

[rich adder]

you're confusing with CharacterController maybe ?

[visual rune]

I think so

Sorry

[wintry quarry]

the default material is not transparent

you need to use a transparent material

[quaint thicket]

I see

Is their a built-in material I can use, or do I need to find something in the asset store?

[wintry quarry]

yes you just need to make one using the standard or Lit shader and set it to Transparent

[timber tide]

creating a new material usually defaults it to the pipeline's lit

[naive pawn]

have you checked the layers to make sure they can detect each other to begin with?

[hexed dove]

can anyone come to speak so i can explain it?

[naive pawn]

no thank you

text will do just fine

[hexed dove]

its complicated but i will try

wiat 2 sec

[wintry quarry]

no, you can share a few screenshots

but basically if it's not working you didn't set it up correctly

you need:

• Both objects must have colliders
• At least one collider must be a trigger
• At least one object must have a Rigidbody

[hexed dove]

oh LOL i just forgot the rigidbody

thank u xD. its been 1H since i tried to fix this

[steep rose]

does the your animator have any exit time to it when playing the landing animation?

[red igloo]

no

[red igloo]

Its not the animator/transitions or the animations it's most likely the camera position script but I don't know what I did wrong

[steep rose]

I was just getting more information to check boxes is all

[red igloo]

I think the problem is the idle position when I remove it that problem is gone

[red igloo]

Your right theres nothing wrong with my script it was the animator

[steep rose]

sorry I didn't respond, it works as you expect it to now?

[red igloo]

hmm kind of but I don't know what I did but the problem is still there but when you are playing you cant notice it lol

[vernal crow]

Can anyone help me make an inventory system or give me a link to a tutorial? Been looking for a while and all these tutorials haven't really worked and I just end up back at square one

[rich adder]

there is no such thing

inventory you're better off making your own system

what you see on youtube is just how different people solved their own way, you essentially will be copying someone elses system and in turn when something break you probably wont know how to fix it, or add onto

much better you build from the ground up the way you want / need it

[vernal crow]

That is what i was thinking

A lot of these tutorials arent what im going for

My only problem is I have no idea how to code it

[rich adder]

of course , every project is different with specific needs

start small, build up as with anything else

you won't learn what's best for you until you experiment multiple times , it will probably not be good the first few times but as you keep doing it you realize what you do or don't do on the next iteration

[vernal crow]

Yeah this project is definitely biting off a little bit more than i can chew in terms of programming so maybe ill go ahead and make something smaller for now. Thanks

[slender nymph]

you should start with beginner c# courses, like the ones pinned in this channel. then when you have some idea of how to use the language, you can break down what you want to do into smaller steps that you can find individual tutorials for and combine that knowledge together to make your stuff

[vernal crow]

Thank you very much will do

[crisp token]

Can I not reference a static class directly?

[naive pawn]

what issue are you encountering when trying?

[crisp token]

I'm trying to reference the static method IFFT2D from static class ComputeFFT but getting a "the type or name space IFFT2D does not exists with ComputeFFT" error

[naive pawn]

have you imported the namespace

[slender nymph]

do you happen to have a namespace and a type called ComputeFFT

[crisp token]

I have it as a class within the same folder

[naive pawn]

and is that class in a namespace

[crisp token]

yeah i had two thanks

[strong plover]

slice effects is a trail renderer

anyone know why the trail is still showing when emitting is supposed to be false?

it stops emitting more trail parts, but the existing ones continue to exist

[quaint thicket]

I want to move a GameObject based on the rotation (Forward and Right) of the players camera, but if I'm looking downwards and move forward, My GameObject will move forward and downwards. How do I make it just move forward, no matter if my camera is looking up or down?

[void thicket]

Get forward vector, set y to 0, normalize

[polar acorn]

You would get your forward vector from the camera, including the downward angle, then use ProjectOnPlane with a plane aligned with your ground
https://docs.unity3d.com/ScriptReference/Vector3.ProjectOnPlane.html

[quaint thicket]

Thanks

[thin lion]

issue is it doesn't stop emitting more, it just continues to emit

[finite mango]

Im using a tileset with 0.5 cell size and when i use

Tilemap.GetTile(Vector3Int.FloorToInt(transform.position));

it looks for the tile on a grid of cell size 1. If i scale transform.position by 2 it almost works but its still off very slightly. is there a better way to do this or should i just add a slight offset to the x and y of transform.position's vector as a woorkaround

The Transform.position is in world space, which is not the space your Tilemap uses. You have to convert it with the Tilemap.WorldToCell(Vector3) method.

Tilemap.GetTile(Tilemap.WorldToCell(transform.position))

[dusk garnet]

Hey is there any courses on the Photon API for servers and networking that I could take?

[teal viper]

What makes you think you would be able to get an answer to that question in a unity server code beginner channel?

[dusk garnet]

it makes me think that because i am a beginner with photon and i want to see if there are any courses. 👍

and im new here so idk anything about this place

[teal viper]

Ugh... Nvm... Read Photon as Python for some reason...

Anyways, there are plenty of tutorials online as well as the documentation, so basically just google.

[dusk garnet]

Yeah I've looked around and most of them are from a couple years ago so I thought they might have been outdated.

Ill look on the Photon documentation and see whats there

[teal viper]

Even if they are outdated, a lot of it is probably still applicable to the modern API.

At the very least the design principles and the concepts behind the API stay the same. There might be changes to method and property names, but these are trivial to fix.

[burnt vapor]

FYI if a (static) class is highlighted like this, then it's definitely known

The error occured due to confusion by the compiler as it used the wrong class, not containing the method they tried using

[naive pawn]

classes can have namespaces?

[teal viper]

Classes can't have namespaces. They can be declared inside nespaces.

[naive pawn]

that's what i thought, so the error is saying that ComputeFFT is a namespace then

[naive pawn]

it's a known symbol, not a known class
like stated originally, there was a class in a namespace of the same name

[teal viper]

No, it's saying that the identifier is not defined. It doesn't know whether the user meant namespace or class, but there is neither.

[naive pawn]

they're talking abouut ComputeFFT itself

[teal viper]

Yeah, if the error is as they quoted, then the issue is with what comes after that.

[tawny quarry]

Hi, my player don't collide with the ground sombody know how to fix it ?

[naive pawn]

i think the confusion (in this convo) is just lack of context, so let me clarify so we can be done here

• namespaces and types are highlighted in the same green color.
• the context here is that there is a class named ComputeFFT inside a namespace, also called ComputeFFT
• the namespace was not imported, so ComputeFFT here refers to the namespace, hence the error about looking for a type/namespace.
  that's why ComputeFFT was found, but not the static method. because it's a known symbol for a namespace, not because it's referring to a different class.

[languid spire]

your player does not have a collider

[naive pawn]

add a collider

might be a good idea to think about that 'someting' (sic) so you dont make the same mistake again

[tawny quarry]

yes !

[burnt vapor]

That wasn't my point

You mentioned that they might have forgotten to import the namespace

[naive pawn]

and they did

[burnt vapor]

The compiler knows that the symbol exists, so it's not a matter of importing the namespace

[naive pawn]

that was the issue

[naive pawn]

it was lmao. the symbol was the namespace

[naive pawn]

@burnt vapor

the fully qualified access would be ComputeFFT.ComputeFFT.IFFT2D(...)

[burnt vapor]

So the issue was ambiguity, not a lack of importing

Or in other words, don't name these things the same

[naive pawn]

it was a lack of importing lol

[naive pawn]

was someone else's package 🤷

it's on the asset store

can we be done with that issue now?

thanks.

[burnt vapor]

Here you go, this was likely the issue: https://dotnetfiddle.net/dBd4Aa

As I tried explaining, the compiler was well aware of the class existing, but it picked a different one.

[naive pawn]

yeah no, that's not it

did you read the error message

[burnt vapor]

Judging by the short conversation, they indeed had two classes of a similar name added, one having the method.

[naive pawn]

"the type or name space IFFT2D does not exists with ComputeFFT"
does that look like ComputeFFT is a class to you

here, try this

namespace Foo
{
    internal static class Foo
    {
        public static void Bar()
        {

        }
    }
}

internal static class Main
{
    public static void Z()
    {
        Foo.Bar();
    }
}
```notice the similar error message?

can we *finally* be done here?

[languid spire]

no, that thinks ComputeFFT is a namespace and it's looking for a class or sub namespace IFFT2D within it

[burnt vapor]

You're not required to answer if it's too much trouble 😉

But yes, it's clear. Things like this can be avoided if we just named things properly

[naive pawn]

you're the one trying to convince me about something that isn't true lmao

[burnt vapor]

Indeed, but I see the exception is in fact different. I was confused by the syntax highlighting

[naive pawn]

so did you miss my clarification message

the one i wrote specifically to clarify the situation

• namespaces and types are highlighted in the same green color.

[burnt vapor]

It doesn't really matter when it's unclear what the code would actually have to be like for such an obscure thing to happen

Also no, I didn't. Wasn't my convo you replied on

I think this is settled then 👍

[naive pawn]

i pinged you. #💻┃code-beginner message

[queen wren]

I have a grid/turn based game, and I've some buttons on screen, so the problem is that the buttons didn't block the raycast, so when you click on a button the unit will get also the command to move on the cell that sit below the button 🙄

I'm trying to stop the action before by raycasting but isn't working.

 {
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     if (Physics.Raycast(ray, out RaycastHit raycastHit, float.MaxValue))
     {
         if (raycastHit.transform.GetComponent<UnityEngine.UI.Button>() != null) return;
     }

also, by using EventSystem blocks everything so I can't use it neighter.

        void Update()
        {
            isPointerOverUI = EventSystem.current.IsPointerOverGameObject();
        }

 private void OnMouseClick(InputAction.CallbackContext context)
        {
            if (isPointerOverUI) return;

Because on this way the canvas cover the entire screen so I can't click on the objects in the scene 🤔

[night raptor]

Why would the canvas objects cover the whole screen?

[ivory bobcat]

Is this script on every object or just your input manager etc?

[queen wren]

Because ScreenSpace Overlay 🤔

[night raptor]

No but only raycast target elements inside the canvas should count for IsPointerOverGameObject

[queen wren]

Looks like Unity 6 EventSystem consider the canvas UI too 🤔

[languid spire]

the canvas has always been UI. It is the base of it

[queen wren]

Ok.. nice to know, at least I know it's not a U6 issue. 😁

[past root]

ive tried setting up player collisions over and over and i cant seem to get it to work my character is just always passing through the objects

https://pastebin.com/raw/3JJMwa27

[languid spire]

so do you have a 2D Collider on both objects and a Rigidbody2D on at least one of them?

[past root]

yeah

[languid spire]

show

[past root]

thats the object

thats player

[languid spire]

be helpful to actually see ALL of the information about the colliders

[past root]

oh yeah sorry

[languid spire]

to start with your Rigidbodies are both Kinematic, so that wont work

[past root]

both of them are the same

[languid spire]

do you know what Kinematic means?

[past root]

like it wont move? doesnt have acctual mass

[languid spire]

no, 'Not affected by Physics'

So, no collision events

[past root]

so should i use static for my object

[languid spire]

best have a non kinematic rigidbody for the moving object

like Dynamic

[past root]

but i dont want my character to have any mass?

[languid spire]

then create a physics material for it

Hi, I need help. When I load another scene my all textures will appear black

Check that the scene you are loading has its lighting setup

also, not a code question

[sleek notch]

oh

[fickle plume]

Use #archived-lighting next time, also check this https://discussions.unity.com/t/loading-scene-additively-causes-change-in-lighting/687635/13

but yeah

It was the problem 💀

[naive pawn]

then set mass to 0 on the rb

Hey, what is the expected way of sharing variables between classes in C#/ Gamedev? I'm taking a course on udemy, and what infuriates me is that while SpawnManager, Player and it's movement limiting, and Enemy and their movement limiting are using exactly the same area bounds, I don't know how to share that one array between these classes

In React I'd have just exported a constant and called it a day, but I guess there's other way of doing that here 😄

[night mural]

You'll get a lot of answers. I think that, especially starting out, it's reasonable to have one central 'store' that holds most of your game state (to put it in react terms)

for constants, you probably want to use ScriptableObjects

(but it could also be, like, one big SO with most of your 'content configuration' in it)

also, the answer differs for unity vs if you're freewheeling it, so keep that in mind

[gray coral]

how can i make my player flip on the y Vector3 localScale = transform.localScale; localScale.y *= -1; transform.localScale = localScale;

[winged vine]

I see, I guess I'm too early into the trip then, as I'm yet to start learning ScriptableObjects, feels like either I'll get that later, or will do that later by myself. Thank you for the answer o/

[swift sedge]

if you only want one instance of a class, you would have a public static Instance property, which allows you to manage the state from anywhere

[night mural]

that will flip them, but it won't rotate them

[night mural]

yeah, the thing is that you'll get a lot of bad answers because most people don't actually ship anything and what you're making matters a lot in terms of how you want to store/manage your state

[gray coral]

yes that what i want revert direction

[night mural]

so my advice is to

1. don't get caught up doing things 'the unity' way, because it's bad. do what makes sense to your programming brain
2. make what you're making and solve your real problems

[winged vine]

I was about to ask, as I can see that ScriptableObject is relatively new addition, and Unity 2019 which I'm at right now doesn't support it yet. I guess I'd have to either find a way, or use 2022

[night mural]

you can use quaternion.lookrotation to build a new rotation that points towards your transform's -y

[swift sedge]

I would just download Unity 6

[night mural]

not sure where that info is from? SOs are old and have been supported for ages

[winged vine]

me trying to find it and failing, but that might be a mistake on my end

[swift sedge]

they've been around forever

[night mural]

https://docs.unity3d.com/6000.0/Documentation/Manual/class-ScriptableObject.html

goes back to 5.2 at least

[winged vine]

https://docs.unity3d.com/2019.3/Documentation/Manual/class-ScriptableObject.html ah I see

[night mural]

You can think of SOs as object instances which you create in unity (at 'design time'), versus in a scene/prefab or at runtime. They exist independent of all of that, so you can reference them within/across scenes

[swift sedge]

they allow you to create an instance of a class and storing it as an asset. It's useful for, e.g. a weapon system, where you want more than one weapon of a specific type

[winged vine]

I see

That sounds cool, I'll try to tinker around with them

[night mural]

so if what you want is 'data that you can read/write from multiple scripts', they're a good solution

[swift sedge]

functionally the same, but different inputs

i dont get it my plater 2d not moving towards the new y pos when rotated

[night mural]

are you moving them relative to their transform.forward?

[gray coral]

yes i noticed first it moved on global

i using localpos now

but still moves forward

or up in this takes

Vector2 newPosition = (Vector2)transform.localPosition + (moveSpeed * Time.deltaTime * Vector2.up);

[night mural]

well that is what you are telling it to do

[gray coral]

yes but up i mean on the new y-as

not literally up

so if i face with y to the left

i should move up but moving the left ofcourse

[ivory bobcat]

transform.up

[gray coral]

i try to flip it

i tried rotation on the x-as

which makes sense

but its kind of buggy

[gray coral]

i dont get it

{
    // Invert the local scale on the y-axis to flip the player
    Vector3 localScale = transform.localScale;

    // Flip the player on the y-axis
    localScale.x = -localScale.x; // Simple flip

    // Apply the new local scale
    transform.localScale = localScale;

    // Log message for debugging
    Debug.Log("Player flipped: New scale = " + transform.localScale);
}```

i tried x and y flips

[steep rose]

do you mean you want to flip the player left and right? if you flipped its Y axis you would flip it up and down

[wintry quarry]

there's nothing in this code that cares about the scale of the object

isn't up up?

It also depends what you're doing with this newPosition vector

[gray coral]

i already fixed it

[wintry quarry]

but uhh... up is upo

[gray coral]

i talking about flipping my player

[wintry quarry]

changing x scale will change which way right and left are

not up and down

[wintry quarry]

you were asking about movement here

[gray coral]

thats old

[steep rose]

was scrolled up

[gray coral]

when i hit a sphere i want my player which is the orang sphere to flip outwards

[rocky canyon]

flip the green axis

[gray coral]

i tried to flip green axis

[wintry quarry]

you want to rotate around the x axis OR change the y scale to -1 to change that green axis

[rocky canyon]

yo how we get our axis widget back?

[steep rose]

if you solely want to move the orange ball move it to the opposing side of your character or flip the parent which in this case is the magenta ball

[rocky canyon]

how do we open that overla menu?

[wintry quarry]

press the ~/` button to get that menu

[rocky canyon]

thanks

[steep rose]

rotating would probably be a better option like Praetor said

got the name right this time

[rocky canyon]

Praet, Praetor, PraetorBlue

[steep rose]

I always mix up the A and E

[rocky canyon]

lol 🙂

[wintry quarry]

It should really be this https://en.wikipedia.org/wiki/Æ#:~:text=Æ (lowercase%3A æ) is,before being changed to ä.

[rocky canyon]

if u pronounce it like Praytor

its easier to know which one comes first

dont we all.

alt and numpad

[steep rose]

I do not

since I never use them

[rocky canyon]

open this guy.. is the easiest

[swift sedge]

for example: Alt + 0178 is ²

discord doesn't really like you doing that though

[rocky canyon]

Alt+255 is Invisible character, had to use that alot back in the days of old HTML

[steep rose]

sweet

figured it out

[gray coral]

why this 2d object moves on the z-as? when i say flip on the y-as. ```// Get the current local scale
Vector2 localScale = transform.localScale;

// Invert the Y-axis scale
localScale.y *= -1; // This will flip the player sprite along the Y-axis

// Apply the updated local scale back to the transform
transform.localScale = localScale;```

[wintry quarry]

That depends entirely on your code that does the movement.

(not pictured here)

oh you're asking about rotation not movement

[gray coral]

yes

[wintry quarry]

that also depends entirely on your code that does rotation, also not pictured here.

[steep rose]

also are you flipping the orange circle solely? If so you will not really see a difference, If you want it to be on the other side of your character you need to either scale the parent, rotate the parent, or move the orange ball via transform
