[wicked fiber]

Im making a 2D game, and I can't figure out why this sprite is rotating on axis other than the z axis. I've tried stuff like locking rotation, but I can"t figure it out.

[teal viper]

Probably due to LookAt

[wicked fiber]

Oh, that makes sense.

[teal viper]

That would make it face the other object

[wicked fiber]

yeah, using vector 3 right?

[teal viper]

Whether it's vector 3 or not is unrelated

[wicked fiber]

Well I want it to look at the mouse, just only using the z-axis

[ivory bobcat]

Try debugging stuff:cs Debug.Log($"Initial Position: {transform.position}"); transform.position = Vector2.MoveTowards(transform.position, player.transform.position, 100000000); Debug.Log($"Position after moving: {transform.position}"); transform.LookAt(mousePos, transform.up); Debug.Log($"Rotation after looking: {transform.eulerAngles}"); transform.position += transform.up * GunHover; Debug.Log($"Position after offset: {transform.position}");

[wicked fiber]

Alr

[teal viper]

Looking means facing the object forward(z axis) towards the target. You don't want to do that in 2d.

[wicked fiber]

Heres some pics of what's happening

[teal viper]

Yep. The blue arrow(representing the object forward direction) is probably facing your mouse position.

[wicked fiber]

Than how would I fix this?

use another axis?

[teal viper]

Don't use look at. Its specifically for 3d

You can assign the correct direction to the object transform.right for example

[wicked fiber]

ok thanks!

for some reason the object is rapidly switching directions

[ivory bobcat]

What does the current code look like?

[wicked fiber]

transform.position = Vector2.MoveTowards(transform.position, player.transform.position, 100000000);
Vector3 mousePos = (Vector2)cam.ScreenToWorldPoint(Input.mousePosition);
transform.LookAt(mousePos, transform.right);
transform.position += transform.up * GunHover;

[ivory bobcat]

He mentioned to remove LookAt

[wicked fiber]

What would I replace it with?

[ivory bobcat]

Instead, you'd be assigning a direction to the right property of transform.

[wicked fiber]

transform.up = mousePos - transform.position;

is that good?

It works!!!!!

thank you both for the help

[ivory bobcat]

transform.right = (mousePos - transform.position).normalized;```

Maybe you won't need to normalize

[wicked fiber]

Oh yeah...

Whoops

[lunar hollow]

Are there any functions for when Animations have Applied in this frame? So that i can modify the transform after the Animation is applied?

[teal viper]

LateUpdate

[lunar hollow]

Oh youre right! The issue was because of my update mode, thanks!

i am doing the junior programmer course on unity learn, there is a part where you have to make a car that can drive and turn and i have done everything as it is shown in the tutorial but the car does not turn when i hold A and D, there is no error in the console, here is my code

https://paste.mod.gg/djtourztnkja/0

[eager spindle]

What's the value of turnSpeed?

Good golly this paste site is not usable on mobile

[latent mortar]

not sure

pretty much copied it off the tut'

that is the problem

the turnspeed's value does not change even tho the horizontalmovement value does

[latent mortar]

(i think)

[rich ice]

if the script is attached to an object (which it should be) you can see the variable's value in the inspector

[eager spindle]

At the top of the page, you declared public float turnSpeed; but didn't set it's value. At the moment, it's 0.
The tutorial might expect you to set the value of turnSpeed by going to the GameObject that has the script, and set the value there.

You're doing Vector3.right * Time.deltaTime * turnSpeed * horizontalInput, since turnSpeed is 0 as you haven't set it, the whole thing is 0

[latent mortar]

yeah the value is 0

[eager spindle]

change it to like 4

[latent mortar]

okay

so simply just

[eager spindle]

that works too

I'm not sure if the gameobject will update it though

[latent mortar]

hmm still seems to be on 0

[eager spindle]

Just remove public for now if you don't need it to be changed by other scripts

[latent mortar]

so how do i do that

[eager spindle]

Change it to 4

[eager spindle]

Click 0

Change it to 4

[latent mortar]

oh🤦‍♂️

[eager spindle]

The ones that are greyed out can't be changed, but this one can be changed 👍

[north kiln]

The value assigned to a serialised field in code is just the default

[latent mortar]

works now😭😭😭

[eager spindle]

Huge

[latent mortar]

thanks for the help tho

wait but one last thing

now i have to manually change it when i click play

how do i make it already at 4

[north kiln]

Just set it before you enter play mode

And save

[latent mortar]

kk

[rich ice]

most things changed while in play mode wont save

[latent mortar]

man i am going to fail at the common sense test

[eager spindle]

there are many things to get used to with unity

don't be too hard on yourself

[rich ice]

yup, you get used to it eventually

[latent mortar]

thanks yall

[radiant zinc]

how do I change the color of 2d scene I cant find no background color setting ( UNITY 6 )

[eager spindle]

a bit of a broad statement uh

can you go to your camera

there's a colour picker in there

just pick the colour you want

[radiant zinc]

nope I dont think so

[eager spindle]

very very old image but something like this

[eager spindle]

It appears grey here but it's a different color when you play the game

[eager spindle]

Open the Environment tab on the right

[radiant zinc]

yes I used to have it too in older version didnt use unity for a while now im back cant find that

ok

[eager spindle]

Unity 6 things

[radiant zinc]

the env

[eager spindle]

Change background type from uninitialized to solid color

Then you'll get the color picker

[radiant zinc]

omg bruh im dumb

also thx helped out

[eager spindle]

Unity 6 things

[radiant zinc]

hey another question I got how do u add an image in the new toolkit ||im trying to figure out how to use it so may be rly obvious but idk it||

[eager spindle]

Ngl I haven't tried it yet but just make sure you have the UI toolkit menu open first and create your first stylesheet

https://docs.unity3d.com/6000.1/Documentation/Manual/UIE-simple-ui-toolkit-workflow.html

https://docs.unity3d.com/6000.1/Documentation/Manual/UIBuilder.html

[radiant zinc]

forgive me if im wrong but isnt this what the stylesheet is

I cant seem to find any componenet thats an image but ig I should rather check the manuals

[ivory bobcat]

This is the beginner coding channel. I'm not certain what you're looking at but if it isn't related to beginner coding, you should try asking in #💻┃unity-talk

[finite mango]

looking to turn off all trail renderers' emmissions when a float called brakeInput is above 0.5f. Ive confirmed that the input is working as intended but the emission never changes from on to off.
function is called in Update()

    private void BrakeFX()
    {
        bool targetState = false;

        if (brakeInput > 0.5f)
        {
            targetState = true;
        }

        if (isBrakeTrailing == targetState)
        {
            return;
        }

        foreach (Transform child in brakeTrails)
        {
            child.gameObject.GetComponent<TrailRenderer>().emitting = targetState;
        }
        isBrakeTrailing = targetState;

    }

isBrakeTrailing stores current state of trail renderers' emission
brakeTrails is the parent gameobject to the trail renderer gameobjects

nvm, this code works. think i entered gamemode before it updated the script last time 🤦‍♂️

Hello all I was wondering if I could get some help with the instantiate, I'm trying to make a simple bow and arrow system which involves getting an arrow to spawn relative to the players using an offset same offset. I've tried tying it to the MainCamera, Player and the bow object the player holds but I'm still not having any luck with it following rotation or across the Z axis. Thanks!

{
    private WeaponSwitch weaponSwitch;
    public GameObject arrow;
    public GameObject player;
    public float fireRate = 2.0f;
    public float draw = 0f;
    public bool canFire = true;
    private bool drawWait = true;
    public Vector3 offset = new Vector3(0, 0, 2);
    public Camera playerCamera;
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        weaponSwitch = GameObject.Find("Player").GetComponent<WeaponSwitch>();
        playerCamera = Camera.main;

    }

    private void FixedUpdate()
    {

 
    }

    // Update is called once per frame
    void Update()
    {
        if (weaponSwitch.one && Input.GetKeyDown(KeyCode.E) && canFire)
        {
            Debug.Log("Fire can be done");
            Instantiate(arrow, new Vector3(playerCamera.transform.position.x, playerCamera.transform.position.y, playerCamera.transform.position.y), transform.rotation);
            canFire = false;
            StartCoroutine(FireRate());
        } while (Input.GetKey(KeyCode.V) && drawWait == true) // Increases draw while V is held down
        {
            draw++;
            StartCoroutine(BowDraw());
            drawWait = false;
        }
        if (Input.GetKeyUp(KeyCode.V))
        {
            draw = 0;
        }

    }
    IEnumerator FireRate() // creates a methord outside of the update timer
    {
        yield return new WaitForSeconds(fireRate);  // creates a timer that waits for number seconds before deloying code below
        canFire = true;
    }
    IEnumerator BowDraw()
    {

        drawWait = true;
    }
}```

[keen dew]

That code doesn't seem to use the offset vector at all

but the easiest way is to add an empty gameobject as a child of the player or camera to where you want the arrow to spawn and then use that object's position and rotation when instantiating

[crisp glen]

Sup guys, anyone know where to find a good tutorial explaining how to make 3D first person player movement with the new input system? I am a complete beginner to scripting.

[devout flume]

I had a question about games & modding, are compiled C# games moddable no matter what? (Using BepInEx or any other modding injection toolkit)

[rich ice]

we dont answer questions about modding here. better off asking in a dedicated modding server

[devout flume]

It's more about knowing whether or not, as the game developer, I can make modding by injection harder (of course it's not impossible, but from what I've seen tools like BepInEx make it way easier than it should be)

But I understand that

[rich ice]

yeah it's in the #📖┃code-of-conduct
although afaik, there's no way to completely stop modding, you can just make it more difficult. il2cpp games are much harder to mod if i remember correctly, i've never used it myself though.

[devout flume]

Yeah that's the only thing I saw online so far. My bad for the question, thanks for your time though 🙏

[sage mirage]

Hey, guys! I am currently trying to create smooth rotation of a game object specifically a crucifix to a specified angle but for one reason the game object is rotating in pivot instead of center. Is there a method or something that can handle it?

wallCrucifix.transform.rotation = Quaternion.Lerp(wallCrucifix.transform.rotation, targetRotation, Time.deltaTime * 2f);```

It rotates the game object to the target rotation but the issue is that it doesn't happen in the local position of the game object but it seems like in world position

[wintry quarry]

Rotation always happens around the pivot

but you are asking about world space vs local rotation?

If you use transform.localRotation it will rotate in relation to its parent

is that what you are after?

It will be using the pivot of the object either way.

[sage mirage]

Yes let me show me very quickly

[tiny bloom]

if I have one prefab that's used as a projectile
is there a way to tell it to pass through specific layers and hit specific layers at runtime?

im trying to do something like an arrow projectile that can be shot by players and enemies
and depending on who shoots, it decides on its own who to hit and who to pass through

[lethal meadow]

how is it moving? rigidbody or code

[wintry quarry]

Layer based ocllisions

If you mean modifying that at runtime:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics.IgnoreLayerCollision.html
Or for a specific Rigidbody:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Rigidbody-excludeLayers.html and/or https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Rigidbody-includeLayers.html

[sage mirage]

Alright, first of all the game object is a parent game object it doesn't have any child objects. The first rotation in the video is what is expected to happen but it doesn't. The second rotation is happening right now like with pivot.

[wintry quarry]

Discord won't embed unless you use mp4

[sage mirage]

I think you can see it right now

https://imgur.com/a/fAEuG9M

[wintry quarry]

the simplest thing to do here is fix your 3D model so the pivot is in the correct place

[sage mirage]

Really? How to do it?

[wintry quarry]

you can also just add an empty parent object to this thing and rotate that

then just position the cross where you want as a child of that

[sage mirage]

For anyone like me who is just starting from complete scratch intending to make games in Unity, this course from the Microsoft C# documentation website is a great first step and I wish I started with it before losing myself in Unity tutorial hell right off the rip. Here is the link if anyone is in the same boat and doesnt know where to start!

https://learn.microsoft.com/en-us/training/paths/get-started-c-sharp-part-1/

hopefully someone finds this useful!

[wintry quarry]

you probably want Origin to Center of Mass (Volume).

But you can also position it manually wherever you'd like with "origin to 3D cursor"

after placing the cursor where you want.

[tiny bloom]

rigidbody

[tiny bloom]

i understand how to do that in project settings
where u make something completely ignore a layer
but at runtime?

[rich adder]

yeah those are really good

[sage mirage]

But I was wondering, why this is happening with the gizmo of some models, and also another question. What if I dont want to fix this problem through blender but instead just want to fix it through code. Is there a way to do so? I am just curious and interested in learning all the approaches.

[wintry quarry]

I just linked the APIs to you

right under the message you responded to

[rich adder]

if you don't want to do it via blender there is the parenting trick #💻┃code-beginner message
..doing this through code sounds like unnecessary nightmare lol..

btw its the pivot not gizmos, gizmos is the visuals you are seeing that represent that pivot point.. a little bit of pedantic note for ya

[foggy yoke]

I'm a newbie, so sorry if this is a dumb question. How can I check if the player collides with a clone (an object instantiated at the start)?

[wintry quarry]

Collision detection is handled via OnCollisionEnter(2D if 2D)

assuming you're using Rigidbodies

[foggy yoke]

I am, but do I attach the script to the prefab?

[wintry quarry]

what script

you can have the collision handling logic on either the player or the obejct the player is colliding with

Do wahtever makes sense in your particular case

[foggy yoke]

Alright.

Thank you.

[brazen aurora]

im trying to make multiple attack types like stabbing and sweep attacks for different weapons. i put these attacktypes inside of an enum. when i only had one it worked fine, but then when i added the sweep type, that works fine, but the stab type doesnt work at all. the attack cooldown doesnt reset, the animations dont work, and it doesnt resest the isAttacking bool. ive been at this for hours please help. tell me if you need more code

[dense sparrow]

thanks

[brisk flint]

what is attack type when you step through, is it pointed at stab or sweep?

if always sweep then its how u are setting attacktype

[brazen aurora]

can i not just set it in inspector?

[brisk flint]

ssetting in inspector does not mean something is not overwriting in code

[brazen aurora]

so how would i go about making it when i select the type in the inspector it will actually overwrite a variable or whatever

[brisk flint]

write a debug log to log attacktype in the start of this method

[brazen aurora]

yh i did that and its just giving sweep so thats always active

so how do i set the attack type with the enum

[brisk flint]

attacktype = AttackType.Stab

[brazen aurora]

ok i looked into enums a bit more and found that its being set to only sweep because thats how i put the prefabs into the inspector, if the weapon prefabs in a different order, its then the stab weapon that works and the sweep weapon that doesnt work

[wintry quarry]

yes you can and this is the preferred way

[brazen aurora]

ive set it in the inspector, however that attack type just ends up being the last weapon ive placed into the scene instead of just being the weapon im holding

[wintry quarry]

that's a broader logical error in your code

nothing to do with enums at that point

        weapon = GameObject.FindWithTag("Weapon");
        if (weapon != null)
        {
            weaponController = weapon.GetComponent<Weapon>();
        }```

This is your problem

You have multiple weapons in the scene

you're just doing FindWithTag("Weapon")

in essence, you are just finding a random weapon

[brazen aurora]

so to fix it would i get the component from the weapon that im holding using the collider?

[wooden hill]

also in OnTriggerStay you're not getting the new weapons controller

weaponController still is the old one

and that's why calling weaponController.Attack() attacks how the old one would because you're literally still using the old one

[wintry quarry]

when you grab the weapon, then you assign the weapon reference

you already have grab logic

use it

in a sense you're already ding it with activeWeapon = collision;

but that's a Collider reference, you need to get the Weapon component too

[brazen aurora]

yh i meant to get the component in the grab function

[wooden hill]

yea just get it in the grab interaction

[brazen aurora]

thank you so much it finally worked

[wooden hill]

as long as you learned from it that's good

[ember tangle]

Plane.Raycast(Ray ray, out float enter);

I dont understand float enter here

[naive pawn]

anytime you see Type name, that's declaring something called name of type Type

here you're declaring a new variable enter of type float

out is a modifier, meaning the function will take the variable given and assign to that variable

you could also write the declaration separately:

float enter;
Plane.Raycast(Ray ray, out enter);
```writing the declaration within the `out` argument is just a shorthand

[ember tangle]

I guess what I do not understand is why that float can become a vector3: ```// Calculate the planes from the main camera's view frustum
Plane[] planes = GeometryUtility.CalculateFrustumPlanes(Camera.main);

//different syntax to regular use so far. shoots ray from ship to target direction.
Ray ray = new Ray(player.transform.position, player.targeting.TargetDirection(player));

//not sure
float enter = 0;

for (int i = 0; i < 4; i++)
{
if (planes[i].Raycast(ray, out enter))
{
pointer.transform.position = Camera.main.WorldToScreenPoint(ray.GetPoint(enter));
break;
}
}```

specifically here ray.GetPoint(enter)

[naive pawn]

it doesn't

it's not transforming the float into a Vector3

it's using enter as just another variable in the calculation of ray.GetPoint

something like ray.origin + ray.direction * enter

[ember tangle]

hmmm I guess that makes more sense

On a related note, my code works if the ray intersects the left or right of the screen frustum, but is above the screen if the intersection is the top of bottom frustum plane:

here is more meaningful image of the one that works:

second one doesnt have that marker on the top side of the screen

[echo ravine]

I am sometimes having some random errors like "something out of view frustum". I searched it and i didn't find a good solution. It also just gave me a dividing by zero error that fixed when i RESIZED THE GAME SCREEN.

[naive pawn]

check scene view to see where it's going, debug your values, etc

[ember tangle]

its amazing how just doing that instantly solved all my problems... 😩

I guess frustum planes are infinitely long.

[naive pawn]

planes in general are infinite

[naive pawn]

you should probably fix the underlying issue, if it's an issue at some specific resolution, then a player would also be able to resize to that value and get the error

[vestal cosmos]

in a game if you have multiple levels how do you make them

[rich adder]

mouse and keyboard usually

[astral citrus]

Hi! Could you help me understand - I know there is Animancer asset in Unity3d asset store, I wonder if it's worth using or there are other options?
I've tried using Unity OOTB approach (with states, triggers etc.) and it feels a bit clunky when I need to do something when animation finishes or mid-animation.
For example right now I have this code to check if Animation finishes to trigger some action

            {
                var state = _animator.GetCurrentAnimatorStateInfo(0); 
                return state.shortNameHash == animationNameHash && state.normalizedTime >= 0.90f;
            }, cancellationToken: _animator.GetCancellationTokenOnDestroy());

[naive pawn]

animation events are a thing

you generally would use those to sync mid-animation actions

[astral citrus]

I feel it's very brittle to use this, since maping done via some string in some place (not sure how to explain it)

[naive pawn]

magic strings?

if you select an animator before setting the animation event, you get a dropdown, so you don't have to type the method name yourself

but it is stored as a string and comes with the risk of accidentally breaking the reference with renaming (for example) of course

[sour fulcrum]

Not that I have a better solution but in general I do agree animation events feel a little gross and tucked away compared to a majority of workflow in Unity

[grand snow]

They arent super reliable so observing the animator state like this may not be soo bad

[naive pawn]

oh yeah i do agree with that. wish there was something more direct and similarly low effort

though i guess it is just kinda the same as timeline events and unityevent callbacks

i do have a utility type to wait for animations completing specifically, that helps

[eternal needle]

could you possibly just use state machine behaviours and the OnStateExit method?
https://docs.unity3d.com/6000.1/Documentation/ScriptReference/StateMachineBehaviour.html

or even Update i guess. either way it gives you access to the same values like normalizedTime

[astral citrus]

Thanks! I will check, didn't see this one. I believe I heared there some issue with it + Animator, but didn't check myself.

[earnest wind]

Hey guys, i need some thinking power again

If i want to make 2 sliders, one for Saturation and one for Value

Then how would i calculate the colors that have to be on both sides in the gradient?

For example in RGB (R) i would just do (0, G, B) - (1, G, B)

[wintry quarry]

Same thing here

but for HSV

in the Hue slider you would do (0, S, V) - (1, S V)

[earnest wind]

Oh so on S for example it would be H, 0, V - H, 1 V

Mhm i see

Thanks

[wintry quarry]

for the saturation slider you do (H, 0, V) - (H, 1, V)

[earnest wind]

I dont think u need to change Hue slider lol

Hue shouldnt change, its like a static rainbow

Typo i meant to say shouldnt**

Hi, i need to make a transparent Window (except GameObject’s) and borderless on Linux, on windows ik there is a simple api for this, but on Linux it’s hard to make. Has anyone ever done something like this before?

[rich adder]

this isn't exactly as trivial as windows, there are different graphics stacks you'd have to start from there then find the bindings for it

libX11 through PInvoke etc.

[copper ravine]

For now I have border less window but it’s black not transparent, and idk what I can do next, maybe other USE flags idk

I use wayland with kde

But unity is running under xwayland

[rich adder]

wayland is even harder to work with

[copper ravine]

Ikkk

In Godot I have this done in seconds

But export unity projects to Godot is pain

[grand snow]

you can use native code with unity so it surely can be done

use UnityEngine.Random instead

you are seeding a new Random instance the same each time 😐

[copper ravine]

Can I paste my code here?

[rich adder]

make sure you use proper format #💻┃code-beginner message

[copper ravine]

Idk how to use that 😭😭

[rich adder]

it explains how lol

for the link ones just paste it on the site , hit save and send generated link

[copper ravine]

https://paste.mod.gg/basic/viewer/labjhfncnmod/0

Like that?

I don’t test it but it’s my idea

[grand snow]

If this was me id make a small lib to do this instead

[rich adder]

my suggestion earlier similiar, use something like GTK# or something to interact with as middleman

..actually nvm you'd need to make a new window with it.

wayland is a bit confusing lol

[copper ravine]

Fr

That is why i use xwayland for unity

[rich adder]

what are you making anyway ? whats the usecase here

if its like a specific app you could just embed unity as library in a native app / toolkit

[copper ravine]

I am determined to fork mate-engine for Linux and I want to learn something about unity and C

[rich adder]

nvm only works on android/ios/windows
https://docs.unity3d.com/6000.1/Documentation/Manual/UnityasaLibrary.html

...depends on how deep the rabbit hole you're going...

[copper ravine]

I think the worst thing in my idea is everything about window rendering

[rich adder]

yeah no idea, you need a way to make those native calls and seems window transparency is a crucial part of the companion app you want to make

[copper ravine]

Idk, how I can search this on google?

Even chatGPT can’t help me

[rich adder]

lookup the process 1 step at time, you wont find specific this is pretty complex

start with finding out how to do it natively maybe a shell command or library, go from there

[copper ravine]

I can do this very easily with python/C++ natively

[rich adder]

so then do it so, then make that call from unity

[copper ravine]

But how connect this to unity

[rich adder]

use interop calls

you can call functions from unity to c++ / python libraries

[copper ravine]

I can with this render full window?

Okey okey, so how to set up project settings?

[rich adder]

settings?

[copper ravine]

Sorry, build settings

[rough granite]

File, Build Profile?

[copper ravine]

YEA

[rich adder]

you don't need special build settings

[copper ravine]

Exactly

Ou okey

Sorry I’m newbie

[woeful scaffold]

Hey guys, im aiming to have the skills to make 3d gamse, do you guys prefer to use a pre-made asset player controller? or do u usually make ur own

I'm pretty sure I can't make it on my own, but I assume it'll be good to learn to do it on my own?

[wintry quarry]

really depends on the game

[woeful scaffold]

guess so, i'm not sure myself, i wanted to have something similar to risk of rain 2 but i think its hard to make

as in the control and third person view

i find myself defaulting to first person as its easier?

[wintry quarry]

No way to learn other than trying

This is a pretty good baseline: https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131

[woeful scaffold]

yeah i made sure to get that

cool stuff, i need to go through the doc of it

[wintry quarry]

But it's not a full solution, it's a building block

[woeful scaffold]

im a little worried about animations and attaching the animations to attacks or so

but thats far ahead so ill just see what i can do for now

[wintry quarry]

Yeah, do that later

[woeful scaffold]

i feel lost when it comes to the code, i used chatgpt a couple times but it really feels just like copy and pasting therefore not learning much

[wintry quarry]

You won't learn by asking CGPT and copying code.

[shell knot]

First question here, sorry in advance if my programming-speak is not up to par yet.

I am so close to adding a "Rotation" to my "Spaceship". I've set up the actions and binds following a tutorial for 3 dimensional movement with some modifications for an Ascend/Descend. All of this is working great, under the ShipMovement -> 3D Vector stuff. But, making the RigidBody of the ship just ROTATE on the Y axis is proving very complicated.

Just looking for some guidance on the next steps, I am trying to add Q and E as Yaw Left and Right controls. Should these also live under ShipMovement for simplicity? Or should I treat them as a new Action entirely like in the screenshot? If I have them as new Actions, I would have to call them separately from ShipMovement in my script, correct?

[wintry quarry]

Well you're not actually showing any code here.

I would probably not make this a single 3D vector input aciton though.

Why not have separate actions for Yaw, Pitch, and Roll?

Oh sorry, misrread your question

definitely do not try to shove rotation and movement controls into a single input action,. no

that doesn't make any sense and will confuse things

Also you haven't actually shown any code here so it's not clear what part you're actually having trouble with

making the RigidBody of the ship just ROTATE on the Y axis is proving very complicated
It shouldn't be.

[shell knot]

I guess my first question is what function should I be using to rotate a rigid body in the first place? I've seen rb.MoveRotation, rb.AddTorque, but can't quite get the right combination of variables to make either work. Here's an attempt using rb.MoveRotation:

//using System.Runtime.CompilerServices;
using Unity.Mathematics;
using UnityEngine;
using UnityEngine.InputSystem;

public class playerController : MonoBehaviour
{
    private PlayerControls1 playerControls;
    private Rigidbody rb;

    [SerializeField] public float moveSpeed;
    [SerializeField] public float rotationSpeed;

    void Start()
    {
        playerControls = new PlayerControls1();
        rb =  GetComponent<Rigidbody>();
    }

    private void OnShipMovement(InputValue inputValue){
        rb.linearVelocity = inputValue.Get<Vector3>() * moveSpeed;
        rb.MoveRotation = inputValue.Get<Vector2>() * rotationSpeed;
    }

And this gives me an error on line 22 (last line) "Cannot assign to 'MoveRotation' because it is a 'method group'".

[wintry quarry]

depends what kind of effect you're going for

on a basic level you can just set the angular velocity based on the current input

or use AddRelativeTorque

And this gives me an error on line 22 (last line) "Cannot assign to 'MoveRotation' because it is a 'method group'".
Yeah this code makes no sense

you can't assign a value to MoveRotation

MoveRotation is a method that you would call

what would work there is:

rb.angularVelocity = inputValue.Get<Vector2>() * rotationSpeed;```

it might not be exactly what you want though because angularVelocity is based in world space, and when yawing a spacecraft you most likely want to do so based on its current rotaiton - sort of a local space rotation

But it might be a good starting point

[shell knot]

that is, thank you. I will play around with actually "generating" the vector2 value

[eager spindle]

the 3d games i make often have mechanics that aren't included with the premade asset so I usually end up overhauling it entirely

[woeful scaffold]

I just finished setting up my movement, camera settings, and gravity

pretty basic stuff but its nice

Now that this is out of the way (for now), time to try and make an interact system

@eager spindle my idea is:
have an "Interact Text" in my UI, make sure it's turned off and whenever a ray that is cast in update() hits it within a range I set, it triggers it to be active + it shows a custom text

is that a correct way of doing it? or is there a better way?

[eager spindle]

Yep this is how I would do it too

[woeful scaffold]

ooo okay

i just am overthinking the idea of the update()

I wonder how i'll get it to be able to do custom functions upon interacting

I assume the ray hits, and inherits the function from the interactive object itself?

I guess I'll need 2 seperate scripts

1 for interactables and 1 for interaction

[eager spindle]

Yep, you should store the object last hit by the ray.
When you interact with the object, call the function on the object last hit by the ray

[woeful scaffold]

storing the last hit within update right?

so it doesnt save it for longer than it needs to i assume

ooooof this sounds basic but im sure im gonna get stuck

[eager spindle]

Took me a while to make the first time I tried it too

[woeful scaffold]

have u ever seen a more cutie patootie player

[eager spindle]

the bean

[woeful scaffold]

LOl is that what u call them here

[eager spindle]

idk

everyone calls it capsules but i call it the bean

[woeful scaffold]

gotta make that nickname so big they replace capsule with bean asset

uldynia show me something u made

[eager spindle]

you can check out my stuff at uldynia.org

[woeful scaffold]

Should the Interact script be linked to the player or the camera itself?

I assume to the player as it moves with the camera?

caffeine junkie..

[eager spindle]

I would put it on the player, but have a reference to the Camera to determine where the player is facing

[eager spindle]

i consume obscene amounts of coffee and monster daily

[woeful scaffold]

which is your fav

[eager spindle]

mango

[woeful scaffold]

the blue one?

[eager spindle]

yep

has sugar but i dont mind

[woeful scaffold]

tastes nice

i like the pink one

punch something?

this one is bussinnnnn

[eternal needle]

There's no off-topic in the server

[woeful scaffold]

oh my bad

I am making the PlayerInteract script right now, i was thinking of maybe adding a bool for canInteract maybe for the future?

[eager spindle]

I would assign a Interactable script to the objects that can be interacted with

[woeful scaffold]

I am doing that exactly, but I wonder if i'll need that bool of "being able to interact" or not

oh wait maybe i should make it so the Interactable itself has a bool not the player

so i can lock chests for example or stuff like that

specific ones*

im struggling with the ray honestly

So i need to give it origin, direction, maxdistance

[raven yew]

Hi!
in my start method, i make my cursor invisible and confined, my cursor then disappears and i can look around, but when i bring up my ui, i make visible and make the lockstate .none but the cursor doesn't come back. is this because my game is not built or is it something else. i cant seem to find the issue.

[wintry quarry]

Show code.

Also make sure the code is running with debug.log

is that really necessary if the ui pops up?

there are none

can anything indirectly affect my cursor?

[wintry quarry]

Ooh yeah good point - if the two actions are bound to the same button they will both get triggered. Debug.Log would have helped figure that out though @raven yew

Although... It is an else if so that probably shouldn't happen?

[woven solstice]

Unity sometimes ignores "Cursor.lockState = None" @raven yew

[raven yew]

ok thank you for the suggestions, ill check them out ❤️

[eternal needle]

i have a sneaking suspicion AI was used for that help

[sour fulcrum]

Source?

respectfully dont know what was going on but 99% sure it was probably a code issue

[eternal needle]

unity doesnt just ignore code randomly, thats not how it works. dont use AI to help others please

[woven solstice]

yeah it was a code issue

[sour fulcrum]

thats not unity sometimes ignoring it

[woven solstice]

when i say unity is ignoring code it means there is a problem with the code itself

[sour fulcrum]

thats not what those words mean

[woeful scaffold]

i did ittttt

i have an interaction system now, with object types like door, weapon

[woven solstice]

cool how long did it take you to do it

[woeful scaffold]

i think like 1.5-2hrs

but hey now i can easily add types

Idk what to try and add now lmao i was so invested

[eternal needle]

this still isnt the channel for these type of posts, there is #🏆┃daily-win and #1180170818983051344 though

[rich ice]

i dont think this is a beginner question, you should try making a dedicated post in #1390346827005431951

[lime sigil]

oh wasn't sure in which of the two to put it
will move it there then

[next fable]

hey guys, trying to figure out what's wrong with my raycasts, etc.

I'm trying to raycast straight down from really high up in the scene for collision checking

my debug output is like this: check hit at (11317.30, -16.58, -5911.03) unit position is (11317.30, 20000.00, -5911.03) local position is (-376.16, -20013.05, -0.48)

the code to output it is

 print("firing check from " + checkPosition + " unit position is " + unit.transform.position + " local position is " + transform.localPosition);
 Ray groundCheck = new(checkPosition, Vector3.down);
 Physics.Raycast(groundCheck, out RaycastHit hitCheck, 100000f, terrainLayer);
 hitDistance = hitCheck.distance;
     print("check hit at " + hitCheck.point + " unit position is  " + unit.transform.position + " local position is " + unit.transform.InverseTransformPoint(hitCheck.point));```

oh yeah, for debugging purposes right now the unit.transform.position and the transform.position are in the same area

if I fired a ray using Vector3.down and check hit and unit position have the same x and z values, why is the local position different?

[silk night]

is your unit scaled/rotated?

[next fable]

it

is rotated around the y axis?

as in, it spins around the vertical axis (like a 2d top down unit) - it shouldn't affect Vector3.down right?

[silk night]

InverseTransformPoint takes scale and rotation into account, if you just want the offset use hitCheck.point - unit.transform.position

[next fable]

InverseTransformPoint is just for debugging purposes, it matches up with the actual issue in my game which is a child of the unit at (0,0,0) is suddently returning (-376.16, -20013.05, -0.48) when I run this raycasting function

I would expect it to return (0,-20013.05,0)

[silk night]

for what is it returning it?

[next fable]

uhh don't quite get you

[earnest moss]

Im new to unity
out of nowhere i legit changed nothing but i got this error

[next fable]

might have deleted a c# file with TrackLineGenerator

[silk night]

child of the unit at (0,0,0) is suddently returning (-376.16, -20013.05, -0.48)
what function is returning that position? is it teleporting to that position?

[next fable]

ah

yes, let me post the full function

[earnest moss]

already asked chatgpt and ive already checked all editor scripts in editor folder and all files are named correct

[next fable]

{
    if (transform.position - previousPostion != Vector3.zero)
    {
        transform.rotation = Quaternion.LookRotation(moveDisplacement, Vector3.up);
    }
    if (!ignoreGroundCollision) //if the unit ignores ground collision, do nothing, otherwise snap to terrain
    {
        Vector3 checkPosition = new(transform.position.x, 20000f, transform.position.z);
        print("firing check from " + checkPosition + " unit position is " + unit.transform.position + " local position is " + transform.localPosition);
        Ray groundCheck = new(checkPosition, Vector3.down);
        Physics.Raycast(groundCheck, out RaycastHit hitCheck, 100000f, terrainLayer);
        hitDistance = hitCheck.distance;
            print("check hit at " + hitCheck.point + " unit position is  " + unit.transform.position + " local position is " + unit.transform.InverseTransformPoint(hitCheck.point));
            Debug.DrawRay(groundCheck.origin, groundCheck.direction * 100000f);
            if (debugObject != null)
            {
                debugObject.position = hitCheck.point;
            }
            transform.position = hitCheck.point + new Vector3(0f, colliderDepth, 0f); //this is not producing results as expected when offset
            print("after collision check, local position is " + transform.localPosition + ", world position is " + transform.position);
        }
        transform.rotation = Quaternion.FromToRotation(transform.up, hitCheck.normal) * transform.rotation;
    }
}```

@silk night each 'unit' contains a number of child objects

the unit moves around and the children snap to terrain, which is where I use this function

I raycast from high in the scene and find the point where the ray hits the ground, then I teleport the unit to that location

[silk night]

cant you just let them snap to hitCheck.position?

[next fable]

transform.position = hitCheck.point + new Vector3(0f, colliderDepth, 0f); //this is not producing results as expected when offset

that's this line of the function

but hitCheck.point is not returning the correct location

[silk night]

but your hitcheck is outputting values as expected

(11317.30, -16.58, -5911.03)
which is directly underneath your unit

[next fable]

well, yes that part is

but the local position is not correct

if hitcheck is (11317.30, -16.58, -5911.03) unit position is (11317.30, 20000.00, -5911.03) local position should be (0, -20013.05, 0) right?

the x and z is not right

[silk night]

localposition - yes
inversetransformpoint - maybe (only at 1,1,1 scale and 0 rotation)

[next fable]

inversetransformpoint I don't actually use in the function - it's just to output the log

[silk night]

print("after collision check, local position is " + transform.localPosition + ", world position is " + transform.position);
so what does this print?

[next fable]

after collision check, local position is (-376.13, -20011.56, -0.48), world position is (11317.30, -15.10, -5911.10)

I'll post a screenshot with all of the relevant debug logs

[silk night]

oh wait, local position is again relative to rotation

so if your parent element is rotated the results will be off

[next fable]

ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

maybe that's why??

[silk night]

most likely

if you rotate an element by 180° and you put a localposition directly below it, it will instead be above 😄

as it takes the parent elements rotation as base

[next fable]

hold on

but only in a certain axis, right?

[silk night]

different axis will return different results ofcourse, but it will respect all of them

[next fable]

here the bottom sphere is child of the top sphere, local position -10

if I rotate top sphere on the y axis only, local position is the same right?

[north kiln]

Why are you not using the return value of Physics.Raycast? It returns false if it didn't hit anything, which is important to know

[next fable]

oh, this is a simplified function

if it doesn't hit anything I raycast up because the unit might be underground

[silk night]

even if you rotate the parent, the localposition of the child will still be y -10

[next fable]

I got rid of those parts cause not relevant to the problem lol

[silk night]

so if the parent is rotated and you place the object directly underneath you have to counteract the rotation in the localposition

which gives you the weird local position 😄

[next fable]

I think I get where you're coming from

let me see if I can fix it

[silk night]

i mean in the world space it IS directly underneath

i dont think its a bug

if you want the offset value just subtract both world positions from each other

[next fable]

i got it

the unit transform was not (0,blah,0) 🫠

it was like -0.02,blah,0.02

almost perfectly horizontal, but when you combine it with raycast distance of 20k, suddenly small error in the rotation becomes 300 units difference in the local position

[next fable]

if the unit was 0, yy, 0, this would not be a problem because the unit only rotates in the y axis

but because it was very slightly off, the local position changes

thanks!!! we got there in the end

[olive oriole]

I always get super confused what type of initialization in my scripts I should put in Awake vs. Start. And honestly, it's quite inadequate to have just those two, so I extended Unity's control flow.

I dont have code atm, but my character cant jump with the new input system. I have the default setup that comes with unity 6.1 and no matter if I use SendMessages or UnityEvents the public void OnJump(InputValue value) function doesnt trigger the jump. When I use the same jumping functionality with the old system it works just fine

Every other function (OnMove, OnLook, etc.) works just fine

Oh yeah im dumb lol

This heat is killing me

No, was just sharing in case anyone has similar feelings.

But nonetheless, pastebin or similar would be useful yeah

Next time I'll do that!

[naive pawn]

yeah so this channel is kinda transient, not really made for that kind of sharing
i don't think we have a space for this unfortunately

not saying it's against the rules, just that it's not really gonna stick around

[slender nymph]

That would be something to throw into #1179447338188673034 probably

[naive pawn]

oh yeah that channel's a thing

[olive oriole]

Ahhh nice! Didn't know that existed. I'll share it later then. Maybe polish it a bit more before creating a formal post.

[brazen compass]

Damn man I've forgotten how to code

Sorry folks, I'm supposed to be alright at this but I have a question

[naive pawn]

just ask your question lol, we don't judge*

-# *results may vary

[brazen compass]

The following is part of a function. thisBlock is a code that denotes a tag for finding a part of a string to split at.

 string pattern = thisBlock + ":";
        print("The pattern is: " + pattern);

        string test = "this is a string that contains t1: and then another t1: and another t1: but also it has a c1: followed by another t1: with some stuff after";
        string[] result = Regex.Split(test, pattern);

        print("RESULT:\n");
        foreach (var line in result)
        {
            print(line);

        }

        string[] result2 = Regex.Split(test, "t1:");

        print("RESULT:\n");
        foreach (var line in result2)
        {
            print(line);

        }

Somehow, despite the identical nature of pattern and "t1:", they are producing different results

How is this possible?

I need the regex pattern to be variable based on thisBlock which is passed into the function. So I can't hard code it obviously. result2 is what I'm looking for, but I can't get it with a variable

I just don't have much experience with regex

[naive pawn]

perhaps try logging pattern.Length to make sure there's no weird invisible chars

[brazen compass]

Oh

It's returning 4...

That's,,, huh. How is that happening

[naive pawn]

cool, that's a very solid hint

try logging each char code out

uhhh not sure how to do that in c#, one sec..

[wooden hill]

null terminated string

[naive pawn]

perhaps something like this

for (int i = 0; i < pattern.Length; i++) print($"index {i} -> {(int)pattern[i]}");

[naive pawn]

that would be horrible lmao

[naive pawn]

ah that 13 shouldn't be there

that's way too low

[brazen compass]

I see

[naive pawn]

13 is a carriage return, aka \r

[brazen compass]

Waow

What a cool edge case

How do I kill it with fire

[naive pawn]

it may be from a line break from windows that you haven't split/cleaned up properly

[brazen compass]

[naive pawn]

where are you getting thisBlock?

[wooden hill]

it's weird because normally /r is followed by /n

oh

[naive pawn]

yep there it is

[brazen compass]

Would it be that \n?

Yeahh. Damn

[naive pawn]

well no

it's more something missing

to split lines properly regardless of format, you need the regex \r?\n

[wooden hill]

your file has crlf line endings

[brazen compass]

Crap this is why you study up on regex before making a text parser

[naive pawn]

eh well it's not really a regex thing

it's a file format thing

[wooden hill]

works on my (linux) machine™️

[naive pawn]

there's 2 flavors of line endings - CRLF/\r\n/Carriage Return+Line Feed, and LF/\n/Line Feed
the former is primarily used on windows, the latter on *nix (mac/linux/etc)

(that's why %n exists in some formatting contexts - \r\n on windows, \n on *nix)

[brazen compass]

So would the best solution here be to pop the carriage return out of pattern or to change my file's line endings

[naive pawn]

either split by \r?\n or change the file's line endings

you can also set your ide to use lf/crlf by default, same for git if you're using that

[wooden hill]

I'd rather split for both cases than have another issue because of this

[brazen compass]

Like this?

[eternal needle]

Do you really need to use \r?\n. It should be fine just using \r\n since you know which OS this is being written on

[naive pawn]

without the space - literally \r?\n

(also yes what bawsi said - if all your files are crlf then this isn't a concern)

[brazen compass]

Oh oops idk how the space got there

[wooden hill]

why take that risk instead of using that regex

[naive pawn]

but also this is a regex, string.Split is split by string iirc

[wooden hill]

oh right lol

[naive pawn]

because regex is slower than normal/direct string manipulation

[brazen compass]

Oh I gotta change that to regex split too don't I

[naive pawn]

it's a much more complex thing, it comes with more flexibility at the cost of being more expensive

[wooden hill]

yeah but I'm sure this won't run every frame

[eternal needle]

Its not a performance issue thing either. Its just not a risk

[naive pawn]

it might make a difference if you have a massive text file

[eternal needle]

They arent gonna go to their 2nd pc on Linux and start editing this file

[naive pawn]

they might have a colleague using *nix (now or in the future) that ends up sending them a file with LF line endings 🤷

[wooden hill]

well while at it make a pre build script that ensures all file endings to be crlf

[brazen compass]

Yippie

[naive pawn]

kinda unnecessary, you can just configure your vcs

[wooden hill]

someone not using vcs

nano

[brazen compass]

I really appreciate that. I was worried it was something exceptionally simple, but nah I actually just didn't know about the carriage return being included in the string. I appreciate it

[naive pawn]

you really just preempted my next message on ides?

[wooden hill]

always has been

[eternal needle]

Another thing to consider here could just be splitting this text asset up into multiple text assets so you arent manually processing this > character to split data. You could have a list of text assets that you drag in

[brazen compass]

I want to avoid this due to the fact I'll be doing a lot of writing

It's a dialogue system

But one with mechanical elements

[naive pawn]

also SOs are a thing if you don't want the layer of parsing (or less of it)

[eternal needle]

An even better reason to split up data. You dont need to be typing this into unity. Write it in a Google docs, copy paste into unity

[brazen compass]

No yeah that's what I mean

i'm typing it in .txt files

This is an example. Essentially I'm trying to make it so I can write in choices and dice rolls into my txt

And then the parser will just go "ah it's a c block. That means I should run the choice protocal"

Etc etc

Should really be using inkle

[eternal needle]

Yea thats gonna get messy fast

[brazen compass]

Maybe lol :P

I'm trying to roll my own for a little bit, and if I get overwhelmed I'll pack it in.

I like to give myself space to do things the wrong way and learn a thing or two before doing it the right way.

[drowsy flare]

Picking up Unity again for a new project, after being away for half a year.
Should I start using 6.x or continue 2022.3.x that I know from before?

[naive pawn]

they aren't that different

if you're used to 2022/have it installed, you could just go with that

[eternal needle]

At the bare minimum if youre going to be writing a ton of text like this, I would look into scriptable objects as Chris mentioned. Idk exactly what you plan to have in one file atm but it'll at least take away this manual logic of "if there's a ... do this!" Because this is incredibly fragile and should never exist. Your scriptable object could have an enum for example

[naive pawn]

(unless you want specific features/bugfixes that aren't supported/available on the old version)

[drowsy flare]

I did a lot of stuff in 2022 that I might eventually want to reuse in this project, so might as well go with 2022 then? Thanks

[brazen compass]

I actually did that for an old project. It was good. Worked well. Idk, I'm just trying a thing that I think will make sense at some point.

[grand snow]

why not use something pre made like inky or yarn spinner? They offer nicer ways to integrate extra data that you can get when parsing later

[brazen compass]

Idk I like making games it's fun

[grand snow]

Ha well not just me

regular expressions can become nasty quickly, see how it goes first i guess

[brazen compass]

I have made really cool things the wrong way before and gotten #goodGrades and now I'm in industry (not a programmer thank god) so I'm enjoying my little freak processes

[grand snow]

enjoy some nice regular expressions i once wrote to extract some data:

        private const string LineValueRegex = @"(?<=\= ?""?)-?[0-9]{1,}.?[0-9]*(?=""?)";
        private const string LineValueComplexRegex = @"(?<=\= ?""?)-?[0-9E+.]+(?=""?)";
        private const string LineArrayValueRegex = @"(?<=\[) ?(\d+), ?(\d+), ?(\d+) ?(?=\])";

[naive pawn]

wdym, regular expressions are so fun

[brazen compass]

Beautiful

[eternal needle]

Consider that if you start with something fragile and build upon it, you're going to have a ton of logic that will need to change if you ever actually want to change it. Look at the file you pasted above, you have a lot of commands that are really easy to mess up. At least with something like an enum you can just select what type of action to do

[short hazel]

My addition to this: there's a parser generator called ANTLR in which you define the grammar and syntax of your "language", and then it can generate a parser for you in quite a bit of different languages. It's Java-based and can generate a C# parser just fine

[eternal needle]

Also a hill ill gladly die on is regex is easy. Mostly people forcefully use it in scenarios they shouldn't and make it harder upon themselves

[naive pawn]

-# i am that person

hell, i made a date parser that checks for valid days according to the month and leap years lmao

[brazen compass]

Please don't worry. I know abt tech debt :P I'm just a silly artist type but I still know how to get for real if I wanted. I'm playing with code. But to put your mind at ease, I graduated in the top 8 students out of 100 students for my game design degree at a prestigious uni.

I'm not a programmer, I'm a designer, so I still am not good at coding. But in terms of development pipelines and tech debt and project management, I know my stuff, I'm choosing not to do it because I have a job and this is play, not work.

[eternal needle]

Truthfully i dont know how to reply to most of that, but the suggestions are specifically because we know you are not the best at coding. Its not about calling out your skills but that you are making the coding side harder for yourself by manually processing strings. It is easier to not do that.
But if you insist on doing it this way thats fine.

[brazen compass]

It's not insistance on one way or another

It is play

It's a lovely way to make games

And hey I'm alright at coding. Sure I didn't know about carriage returns but like. Idk I've made cool stuff.

Idk I'm saying dw about it man

[grand snow]

vs code can show "hidden" characters which is useful when debugging stuff like this
other editors like notepad++ can be told to show hidden characters too

I remember once needing to write something to get rid of these weird alternate new line characters from a document this writer did for us so this stuff happens

[naive pawn]

it's not in the source though, not sure that'd be useful for this situation in particular

[grand snow]

its more to idenfity if there is anything non visible in some text from somewhere

[naive pawn]

ah you mean like with the debugger?

[hardy galleon]

hello guys i cant load scene for client with NetworkSceneManager i read the document but i didn't understand at all because of my language barrier. I just know i have to load scene with host or server and Network doing rest of sync for clients.

Guys how can i make a healthUI script with using observer pattern also event system?
I tried to make the code but i cant because i have to get max health and calculate healt / maxhealt. I guess i cant use observerpattern here its not good. What do u think?

[rich adder]

ofc you should use events.. and Observer pattern is events

not sure what you mean here

tried to make the code but i cant because i have to get max health and calculate healt / maxhealt.

[kindred iron]

i need to update the ui so i have to get maxHealth of the player

[grand snow]

the player has an event for when its health changes, the UI subscribes to this to know when to refresh itself

[rich adder]

just pass the current health thats updated in a float

like OnHealthUpdated?.Invoke(currentHealth)

[kindred iron]

yeah ik but i have to get max health so i can make the percentage like health / maxHealth

[kindred iron]

but is it really good to make a new event for that?

[grand snow]

if you subscribed to the event on your player instance, you can get this "max health" then

or give both as event args: public event Action<float, float> OnHealthChanged;

[rich adder]

why not ?

if you want you can also make it a struct or tuple to pass multiple values at once
there is also delegate type you can use so you can give the floats labels and be more explicit etc

[kindred iron]

hm ok ima try this way ty guys

[ashen hound]

helu, im trying to implement audio into my physics based game but sofar it turned out either delayed or glitchy
because when changing or playing based on linear velocity its rather meh because the velocity is changing a lot because the thing iwant to add sound to is bumping a lot in tight space

im trying to add friction sound

[rich adder]

do you have an example or something ?

[topaz hatch]

Morning everyone, I'm trying to disable the Image component of objects in a specific list through code. For whatever reason the Component.enable call does not work. Here is what I have:

` if (imgBulletIndex < imgBulletClips.Count -1)
{
Image imgDisplay = imgBulletClips[imgBulletIndex].GetComponent<Image>();
imgDisplay.enabled = false;
imgBulletIndex += 1;

}`

[ashen hound]

how do i snip code?

[rich adder]

are you sure this is the Unity Image from UI

[topaz hatch]

Oh? Let me re-type that to be sure.

[rich adder]

hover over it should tell you which namespace is coming from

I am very very new to unity coding and want to make a simple 2D movement system, what would the best way to code that be?

[slow idol]

do you know C#?

[topaz hatch]

It didn't seem like it was. Now the whole initial getComponent Code is wrong. Let me type out my reference get again and see what happens.

[rich adder]

check resources pinned and start from the basics

[rich adder]

is your IDE configured ?

[slow idol]

is there a way to modify Unity’s built-in scripts? for example, add a pitch variation to all audio sources by default, without extra code upon instantiating one

[topaz hatch]

I wouldn't know

[wooden hill]

you can also look at the top of your file to see which it is "using"

[rich adder]

but probably configure your IDE if it isnt;

[past halo]

Lets gooo i managed to kitbash two different tutorials together to get the movement, physics and input systems i wanted raah

[topaz hatch]

It seems to be using the 'Image' from the Visual Editor.

[rich adder]

modify all the audio sources component? no unity wont let you touch their components since they are built to interact in the C++ side

[slow idol]

damn :(

[wooden hill]

yea its the first recommended for me too, but you have to choose 2nd

[rich adder]

I belive VS puts whatever namespace is first if you dont explicitly select it

[topaz hatch]

Okay I'm adding in that library

[wooden hill]

just click on 2nd and it should do that

wondering if we can set priority to unity first

[topaz hatch]

UnityUI is not even showing up in the drop-down. Trying to fix up my library calls now

[wooden hill]

oh then probably not set up right

[rich adder]

which editor are you using

[topaz hatch]

Microsoft Visual Studios

[wooden hill]

Visual studio Code ?

there is a difference in like vs2022 or vsc (vscode)

[topaz hatch]

I feel like this is a recent issue for me. I fixed up the libraries at the top so lets see if this code works now.

[rich adder]

check here
https://unity.huh.how/ide-configuration/visual-studio
https://unity.huh.how/ide-configuration/visual-studio-code

if you did all the steps n still not working, check the troubleshooting section

[topaz hatch]

There we go. It works.

Hmmm, I really don't remember having to care about knowing this in the past. Like Unity 2018 and such.

BUT, it's good to know now so in the future I can let others know

[kindred iron]

there is a new problem. I made the script separately so that i can put the health script to anything. But if i invoke a event this happens on every gameobjects where i put the healthscript and even tho the health is not players my ui updates (5min afk)

[topaz hatch]

Now I know why the older tutorials always did the using Unity.UI thing at the top.

[rich adder]

that doesnt sound right, show the code maybe ?

[grand snow]

if the events not static its for that instance only, you are confused 😆

[wooden hill]

how old are we talking

[rich adder]

Unity.UI was a thing ?

[grand snow]

no its UnityEngine.UI

[topaz hatch]

Yeah. My bad

[grand snow]

System.Collections.Generic ❤️

[topaz hatch]

Before Unity 6 for sure.

[wooden hill]

I think that was just an example. the main thing being that you have to put the using statement yourself

huh im pretty sure even in unity 5 i didnt do that

what ide were/are you using?

[rich adder]

Unity.Cinemachine has entered the room

[topaz hatch]

I didn't know there were other code uses for the Image call. But for context on myself I am someone who only knows C# through Unity. So I am not familiar with the hard C# programming stuff

[rich adder]

I guess it makes sense now that 3.0 is Unity.Cinemachine instead of redone as UnityEngine ig since it was an asset acquired

[grand snow]

Unity.Collections too

guess for new stuff they decided to do this

[rich adder]

Image is a class , so yeah its a pretty common name for a class

[topaz hatch]

oooh okay

[rich adder]

namespaces help encapsulate these within their own "group"

[topaz hatch]

So Image is a general C# class and Unity has it's own UI version called Class?

[rich adder]

na Image is just a common class for multiple different namespaces

the only ones that are built in are ones usually found in the System namespace

[wooden hill]

not a general c# class at all, its from the visualstudio editor package. The other two are from unity.

[rich adder]

System.Drawing has one but don't think it woks in unity

https://learn.microsoft.com/en-us/dotnet/api/system.drawing.image?view=windowsdesktop-9.0

gool ol windows forms (i think?)

[kindred iron]

the code is:

using System;
using UnityEngine;

public class Health : MonoBehaviour
{
    [Header("Health")]
    public float health;
    public float maxHealth;
    public float defense;
    public float defenseMultiplayer;

    void Awake()
    {
        health = maxHealth;
        defense = 0;
        defenseMultiplayer = 1;
    }

    private void OnEnable() => EventManager.OnDamageTaken += Character_OnDamageTaken;
    private void OnDisable() => EventManager.OnDamageTaken -= Character_OnDamageTaken;

    private void Character_OnDamageTaken(DamageEvent damageEvent)
    {
        if (damageEvent.DamagedObject == null)
            return;

        if (damageEvent.DamagedObject != damageEvent.owner && damageEvent.DamagedObject == gameObject)
        {
            TakeDamage(damageEvent.damageAmount);
        }
    }

    public void TakeDamage(float amount)
    {
        //EventManager.SendHealthChange(health, healthChangeAmount, maxHealth);
        health -= (amount - defense) * defenseMultiplayer;

        if (health <= 0.1)
        {
            Die();
        }
    }

    public void Die()
    {
        Destroy(gameObject);
    }
}

[rich adder]

yup EventManager.OnDamageTaken seems to be a static event so everyone(Health) subscribed to player taking damage will call that methodCharacter_OnDamageTaken

[kindred iron]

yeah thats the problem

even the enemy will invoke the event

[wooden hill]

Just like you checked the owner there you would need to check on your ui if its the player

[rich adder]

yeah so don't make it static

why should ALL health listen for it

[kindred iron]

wdym

the same health scripts has everybody

it changes nothing

[polar acorn]

I believe they mean don't make it static

[wooden hill]

yea so everybody will trigger the ui to update

[kindred iron]

https://cdn.discordapp.com/attachments/1297962203428945960/1366068891419283568/togif.gif

[rich adder]

everyone is Reacting to the same static event

rather than listenening for a specific instance invoking it

every health component should subscribe to their own instance object they are on

[visual linden]

I generally don't mind static events, but it's true that there seems to be some spaghetti happening in this specific case.

[polar acorn]

To be honest, why is the health script the one subscribing to an event? It seems like it should be the source of the events

The script named Health should probably be the canonical source of data

[grand snow]

that would make too much sense

[rich adder]

Yeah I guess they wanted to make it more modular but you should just call a TakeDamage method from whatever is taking damage from

[kindred iron]

there is one already:

public class EventManager : MonoBehaviour
{
    public event Action<DamageEvent> OnDamageTaken;
    public static event Action<float, float, float> OnHealthChanged;

    public static void SendDamage(DamageEvent damageEvent)
    {
        OnDamageTaken?.Invoke(damageEvent);
    }

    public static void SendHealthChange(float currentHealth, float healthChangeAmount, float maxHealth)
    {
        OnHealthChanged?.Invoke(currentHealth, healthChangeAmount, maxHealth);
    }
}

[rich adder]

health component can have events for UI and sound effects or whatever else as Invoker instead of listener

[naive pawn]

yeah, we're saying to change the source of the events

[polar acorn]

So, this script is the canonical source of Health? This script represents the one overall Health data that everything shares?

[kindred iron]

can u give me an example for ui pls

[kindred iron]

for events yeah

like the name says event manager

[rich adder]

Player/Enemy takes damage call TakeDamage on health component
on Health component INVOKE an event OnHealthUpdate?Invoke or whatever (Other scripts subbed to it react, like UI for player specific etc.)
this way other objects can have it(Health) as long as they call Take Damage on Health component

[polar acorn]

So then what's the problem? If this is the one source of information about the concept of "Health" it seems to be behaving as expected. This one thing changes, everything that listens to it updates.

[kindred iron]

but when enemy gets damage wouldnt the health ui change again?

[grand snow]

isnt that the point

player damaged -> notify stuff -> update ui?

[kindred iron]

no this ui just for the player

[grand snow]

then make it do just that???

[rich adder]

so then only UI listenes for event on Health for player

[kindred iron]

enemy damaged -> notify stuff -> update ui

[grand snow]

have some amazing art

[rich adder]

You can have the same event in Health, that doesnt mean other scrips have to listen to that event and react the same way

[kindred iron]

can u give me an small expamle pls?

[rich adder]

I did

[kindred iron]

its hard to understand for me 😭

[rich adder]

put OnHealthChanged event in Health
then in player you += to it and react whatever you want from it, UI , Sound etc.

[kindred iron]

in the player controller u mean i should " += " ?

[wooden hill]

If you know how to make events then that means you're almost there

[rich adder]

in the UI script or whatever other scripts you want reacting to that event from the player One

all HEALTH have that event, but only in the Player one do you want to += for the UI or anything player specific reaction

for Health on enemy maybe you'd only subscribe to it for a sound to play or whatever else

[kindred iron]

if i change something on health script it changes for enemy too

[grand snow]

public class PlayerUI : MonoBehaviour
{
    [SerializeField]
    Slider healthSlider;

    public void Init(Player player)
    {
        player.OnHealthChanged += (float newHealth) => {
            healthSlider.value = newHealth;
        };
    }
}

UI subscribes to event on player and updates itself

[polar acorn]

You have one script that handles all health events. That script is the canonical source of all information about "health". If you want multiple different "health"s, you cannot have a single script with a static event handle it all. You would need to include information about which "health" you are sending a message about.

[rich adder]

change in what way ? you mean the static event you put ?
otherwise for the fields, that shouldnt be happening, every health script is its own component when its on gameobject

[kindred iron]

so i need to send a like gameobject so i can understand which health script it invokes. Did i understand correct 😭?

[grand snow]

plz ditch this dumb design

[polar acorn]

You would have the Health script be the one with the event, and other things subscribe to that. Rob even showed you how you could have your UI listen for a specific object's event

[visual linden]

(Also just a heads up, I think posting gifs is against the rules)

[kindred iron]

are u sure. then i wouldnt be able to send gifs

at this point

[polar acorn]

Reaction images in general, not "gifs" as a format

[rich adder]

no reaction gifs this obnoxious

[grand snow]

[man talking to brick wall meme]

[visual linden]

Yes, sorry, reaction images specifically 😮‍💨

[naive pawn]

[man tapping forehead gif]

[kindred iron]

so i shouldnt send this gif?

[naive pawn]

yes

[kindred iron]

oh

[naive pawn]

if you want to react, you can use reactions
reacting in general isn't against the rules, but using images/gifs is kinda obtrusive - that's why that specifically is against the rules

[visual linden]

Going back to the problem though, I really think Rob's code snippet above illustrates a much better approach. You could give that a go

[kindred iron]

if i dont make it static how can i invoke the event?

[rich adder]

being static has nothing to do with ability to invoke an event

[kindred iron]

if i cant reach the event i cant invoke it

[visual linden]

Well, you need a reference to the instance, which is probably what they mean

[rich adder]

being static just means only 1 of that event exists, and everyone subscribes to it
(which in this case is not what you want)

[polar acorn]

#💻┃code-beginner message

[kindred iron]

but there is no event in playercontroller

[rich adder]

the player doesnt need any events
at least not now

[polar acorn]

Replace Player with whatever script has the event

This is what is known as an "example"

[kindred iron]

eventmanager

[rich adder]

forget that crap right now

[polar acorn]

EventManager should not exist

[kindred iron]

why

[polar acorn]

Because you want more than one thing to have "Health" right?

[kindred iron]

wdym with thing?

[polar acorn]

I mean thing

Object

Instance

[ember tangle]

It should be a health manager or a unit manager, not an event manager

[kindred iron]

oh yes

[polar acorn]

So, if there are multiple things that have a "Health" value

You can not have one static event handle all of it.

Static is shared between everything

[grand snow]

my example is meant to be that you initialize the UI with the specific Player/Health INSTANCE that matters.

[ember tangle]

and if you need static access use a static instance of the class, not static events

[kindred iron]

why cant i and what happens if it has

[wooden hill]

There are many solutions to this.
If you really want to use an "EventBus" then you would have call the ui only from the player's health reduction and not literally every entity that has the health script

[kindred iron]

i got it a lil better now :D

[kindred iron]

but at this point i have to make a new script as PlayerHealth

[polar acorn]

You literally cannot. It's very simple. One thing is not two things.

Think of it this way, you have two cats. Those cats have two food dishes in different rooms (because cats fight over food). You ask someone to let you know when a cat's food bowl is empty. You're in your room, someone walks up to you and says "A Cat's bowl is empty".

Which cat do you go feed

[kindred iron]

guys i gotta go rn i will come back in 30 mins ty for ur helps 🙏

[wooden hill]

Where did you learn events from btw?

[ember tangle]

Great analogy tbh

[stuck field]

Neither, are you trying to make them fat? If you've filled both bowls already, you would only feed them both at their next meal times, but don't take this seriously, it's just not a good way to think about it as realistically you would never feed them once their bowl is empty, at that point just give them a massive pile of food 😭

[polar acorn]

"Local cat never been fed in entire life, reports local cat"

[ember saffron]

i don t understand the issue?

[stuck field]

Think about what could be missing 🤔

[slender nymph]

what is Random.Range(lowestPoint, highestPoint) 0) supposed to be

[ember saffron]

im just beginning to start learning scripting so i dont know

[sharp jay]

Comma innit

[naive pawn]

wouldn't the error message tell you

[naive pawn]

"expected a ) or a ,"

[polar acorn]

What's the error say

[naive pawn]

yeah exactly

[grand snow]

yea what does "expected comma" even mean smh /s

[polar acorn]

Yeah, pretty clear

[ember saffron]

do i remove the ,? or

[polar acorn]

It tells you what it expects to be there

[sharp jay]

We need british translation for the console

[polar acorn]

and you can see that it is not

[naive pawn]

it says it expected a ,

you didn't give it one

[sharp jay]

"oi fam. missin a comma innit"

[polar acorn]

remove what ,?

[ember saffron]

but then i have two commas

do i delete the one after the )

[polar acorn]

why would you put it there

[sharp jay]

Oh. we're doing this are we

[naive pawn]

oh god

[polar acorn]

Do you know what a comma does

[sharp jay]

I see not much has changed in 3 years 😎

[naive pawn]

it's saying the 0 is unexpected, because it expected a , first

[slender nymph]

okay now what do you think Random.Range(lowestPoint, highestPoint) 0 is supposed to be

[ember saffron]

i don't know why people are getting pissed off?? from what i remember this is code-beginner 😭 im literally just starting out so, no!! i dont know anything abt coding atm

[ember saffron]

it's like

[sharp jay]

PERFECT

do that

[polar acorn]

Because you literally have an error message telling you exactly what to put and you just won't read it

[polar acorn]

like what

[slender nymph]

I do doubt that

[rocky canyon]

well don't do that

use letters for words

[frail hawk]

dion if your rotation is weird after instantiating, you might want to use Quaterion.identity instead transform.rotation, just saying now

[sharp jay]

who are these bogans doing youtube tutorials

jesus

[ember saffron]

👍

[ember saffron]

dude i gen understand nothing from the tutoria

im tweaking

he's going so fast

[rocky canyon]

you have to build up exposure..

[ember saffron]

im just basically copying off code

and playtesting it

😭

[rocky canyon]

thats just the way it feels for any beginner

[sharp jay]

watch @rocky canyon tutorials instead

[short hazel]

Look at the difference between the "O" in Offset and the zero of the line 40 indicator

[rocky canyon]

took me hours to do my first 15 minute tutorial

nothing stopping u from pausing as u go..

dont try to do it all in one go

[kindred iron]

from yt, why?

[ember tangle]

Make slight changes to the code of the tutorial so you can better understand what is going on and get more comfortable messing around.

[slender nymph]

that is a capital letter not a number

[ember tangle]

Dont just copy

[kindred iron]

i couldnt cuz idk which cats bowl empty is

[polar acorn]

Exactly.

That is why you cannot have a single static event handle multiple things having health

[ember saffron]

oops

[kindred iron]

oh ok ty for the very good explanition u are a genius :D

[kindred iron]

and now how should i do?

[slender nymph]

also next time it would help make it more obvious if you didn't intentionally crop the top part of the video out because line 28 has a 0 on it and the difference between that 0 and the O is fairly obvious

[polar acorn]

As we said, the thing that actually controls the health should be the thing that has the event (Not a static event), and things that need to listen for changes in a specific object's health would subscribe to that object's event

Furthering the analogy from before, imagine if instead of having one guy tell you when any cat's bowl is empty, imagine if you had as many guys as you had cats, and each one checked one bowl. When that specific guy shows up you know which cat to feed

[kindred iron]

OH NOW I UNDERSTAND IT FINALLYY

but i have a question

at this point i have to get the health of the player

so i can get the event

dont i?

[sharp jay]

you can get anything you want

[sharp solar]

inside classes
defined variables are allocated new memory for every new instance of that class
do defined methods take up more memory for every new instance as well or does c# handle that part

[wintry quarry]

no

the method is part of the class, not part of an instance in memory

[rocky canyon]

Think of methods as "instructions", not data. You don’t need a copy of instructions for every object—just one shared version. But instance variables are data, and each object needs its own set.

[kindred iron]

at this point i have to get the health of the player
so i can get the event
dont i?

[rocky canyon]

try it and see

[polar acorn]

You would need to tell the UI which Health component it should subscribe to the events from. This is an example of how you might do that:
#💻┃code-beginner message

[rocky canyon]

don't forget to unsubscribe ondestroy or disable.. don't want memory leaks

[kindred iron]

but how can i init it in inspector

[polar acorn]

Do both objects exist in the scene before you start the game

[kindred iron]

wdym both?

[rocky canyon]

the health stuff and the ui stuff..

[kindred iron]

oh ok

[polar acorn]

The thing that has the Health and the thing that needs to know about Health

[rocky canyon]

reference one with the other 😉

[sharp solar]

do serialized fields show during runtime or only in editor
otherwise why do serialized field over public

[polar acorn]

Serialized Fields let you set a private variable in the inspector

While still being private

[sharp solar]

so it doesnt show when interacting with the class in script?

[kindred iron]

they both exit. i didnt understand what u meant exactly

[polar acorn]

Before you hit play, do both objects exist in the scene at the same time

Or are either of them spawned in at runtime

[rocky canyon]

say you want a variable thats "private access" only the script can access it..
but lets say u also want to assign that in the inspector... sooo when ur script begins.. it has all the relevant data it needs

you can use [SerializeField] private ... in that case

[sharp solar]

ok

[rocky canyon]

no reason for it to be public just to have it exposed in the editor

[sharp solar]

is there any performance cost associated with public variables or is it just a cleanliness thing

[naive pawn]

there is, it looks nice 🙃

[wintry quarry]

yes - it gets serialized

[naive pawn]

(extra space)

[sharp solar]

but serialized private is also serialized

[wintry quarry]

that costs memory and some cpu to copy it arund

[kindred iron]

yeah player and healthui exit

[rocky canyon]

i knew that 🤪

[naive pawn]

between a public field vs a private field marked SerializeField?

[polar acorn]

So then you could just make a variable that holds a reference to a Health object and drag it in

[sharp solar]

sure

yes

[polar acorn]

Then on Start, subscribe to its events

[kindred iron]

public variable?

[polar acorn]

Or serialized

[kindred iron]

ohh ok

[rocky canyon]

having a public variable thats never needed outside the class just is another vulnerability... accidental changes can be made..

[naive pawn]

there probably would be a difference just based on how unity acquires the variable but they both would use reflection anyways so there's not gonna be a significant difference

[kindred iron]

but wouldnt it be like a lil messy because we still trying to get the script from our script then we dont use observerpattern at this point right?

[sharp solar]

so its a cleanliness thing

[rocky canyon]

well for me yea..

[polar acorn]

You are still only modifying the UI whenever necessary. You're not querying the player every frame to see if it changed

[rocky canyon]

when i first started coded i made EVERYTHING public

[hexed terrace]

It's called encapsulation

[rocky canyon]

lmao

[polar acorn]

Public vs. Private is like putting your clothes in a drawer or just piling them up on the sofa.

It's easier to access them on the sofa but a whole lot harder to find the specific thing you're looking for.
