[acoustic sinew]

Here is the updated line for the ground check isGrounded = Physics.Raycast(transform.position, Vector3.down, groundCheckDistance, LayerMask.GetMask("Ground"));
But for some reason it's not detecting the ground.

[spring creek]

transform.position is the middle of the gameobject. Is the distance half the height of that gameobject or less? Then it won't reach

It needs to be longer, or moved down

Is my guess

[acoustic sinew]

Oh, I see

[hard viper]

it depends on where he put the origin of the transform

[spring creek]

Yes

[main shuttle]

Everything that Aethenosity said, but also, Debug.DrawRay is a good way to debug these kinds of problems.

[hard viper]

I normally use Cast to cast the whole collider down, but it is much more expensive

I do that because my terrain can get very wacky

and it avoids weird shit at edges

[spring creek]

Plus less precise for things like edge detection. I do a tripod of raycasts

[hard viper]

i don’t think it is less precise for edge detection. it’s just different

[spring creek]

I mean. It IS less precise. It will detect in a larger area, which by definition is less precision

It works though, don't get me wrong

[hard viper]

i don’t think that’s what you mean

it’s less specific

[spring creek]

Wrong. I meant what I said? Precision detection of a tiny area. Well, three tiny areas you can treat differently

[hard viper]

specificity has to do with the scope of what you are detecting. Precision has to do with the spread of quantitative information

less precise would mean that it would give you a more variable number

[spring creek]

Exactly. Which is why it is precision, not specificity

[spring creek]

Exactly what I'm saying it does

[hard viper]

i mean… it’s looking for the one point of contact under you

it’s getting that point’s coordinate

[spring creek]

And that point could be anywhere in a wider area if it catches the edge of the collider. Less precise

[hard viper]

if a raycast hits a rough surface, you could be hitting the wrong point, but be getting an extremely precise measurement of that point’s coordinates

that is specificity

[spring creek]

Ok, pedant as needed. Go on with your meaningless and incorrect distinction as needed. Later

[hard viper]

🤷‍♂️

it’s easier to explain with biology maybe. A specific antibody is really good at only hitting the one thing it is supposed to hit, which is like #times you hit what you wanted / total hits

that is specificity

a precise measurement would be when you look at a measurement performed with that antibody, and see how much the number of hits varies. That is precision

[acoustic sinew]

if (isGrounded && !Input.GetKeyDown(KeyCode.LeftShift)) shouldn't this be a valid statement? It's not throwing syntax errors, but the if statement condition is still being met when I'm not pushing leftshift

[hard viper]

keydown is true the frame you press the button

[spring creek]

You are checking if you are NOT pressing left shift with the bang symbol

[acoustic sinew]

Yea, I want to check to make sure I'm not pressing it

[hard viper]

so that second part is usually true, except for the one frame that you press left shift

[acoustic sinew]

Wait, so it's not checking if I'm holding the keydown, only if it's pressed

[hard viper]

GetKey is true WHILE it is held down

[rigid island]

!Input.GetKey

[hard viper]

GetKeyDown is true WHEN it is pressed

for one frame

[acoustic sinew]

Ahhh okay

[hard viper]

GetKeyUp is true on the one frame you let go

[hard viper]

I’m thinking about making an Interface for making Monobehaviours act properly when an object is pooled.

I’m thinking about making IResettable, which is an interface with only public void ResetBehaviour(). This is supposed to just bring back the behaviour to the state it should be at right after Awake, OnEnable, Start are called. Is this a good idea, or is there a smarter way to automatically bring all my components to this state?

[heady iris]

sounds reasonable. you'd call it when you return the object to the pool

Note that you'd need to either do a cast or make the pool hold abstract classes that implement IResettable

[hard viper]

I would call GetComponentsInChildren<IResettable>(), and call ResetBehaviour on each

the pooling class itself won’t permanently store references to behaviours

[thick terrace]

an alternative is the way unity's ObjectPool class works where you supply delegates when you create the pool which get run when you get/release an object, the benefit is you can avoid adding an interface to everything that goes in a pool

[acoustic sinew]

So I'm trying to figure out how to carry the momentum of the player into the jump, but not allow the player to change the momentum while in the air

[spring creek]

Depends on how you're moving. You could do an AddForce in impulse mode for the jump and disable any horizontal movement at the same time if you are using velocity or addforce based movement. With transform movement, you'd need to handle it differently, probably just disable horizontal input and keep doing the horizontal movement in the same direction and speed until you're grounded again

[acoustic sinew]

{
    movement = new Vector3(horizontalInput, 0.0f, verticalInput);
    movement.Normalize();
    transform.Translate(movement * walkSpeed * Time.deltaTime);
    if (isGrounded && Input.GetButtonDown("Jump"))
    {
        Vector3 momentum = rb.velocity.normalized;
        rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
        rb.AddForce(momentum, ForceMode.Impulse);
    }
}``` This is what I have for walking, and when I jump all movement stops except in the vertical direction. However, when I don't jump and release one of the movement keys the player decelerates rather than stopping all at once

[spring creek]

@acoustic sinew Yeah, you are using transform.translate, which is like teleporting small distances. It doesn't give you velocity in the same way, so you can't keep your momentum that way. It's more like you're standing still at one point. Then standing still at the next point. Then the next...

You'll have to just keep translating sideways with the movement you had before the jump, but that would get tricky with the y parameter I guess. Maybe use its own y position in that part? Not sure if that'd work

[acoustic sinew]

Hmmmm, so maybe I should not use translate and do .Addforce In those movement directions

[spring creek]

If you want to. It works quite differently and it has a lot of considerations.
You'd probably find it a lot more "slippery" than what you're doing now

[acoustic sinew]

BUt what's weird, is when I release the movement keywhile grounded the player moves as if it does have momentum

[spring creek]

Are you using GetAxis?

For input

[acoustic sinew]

Yes

[spring creek]

Yeah, that has smoothing implemented. You'd use GetAxisRaw to avoid that. But yeah, not sure exactly why that doesn't carry over to your jump

Probably because of the addforce where you pass in momentum actually

Since your momentum is 0, you are kinda halting it with that call

[acoustic sinew]

That makes sense. This gives me an idea on trying something, so brb

I like the feel of adding the force, just gonna have to do a lot of tweeking to get it feeling just right. However the force it being adding in the world axis rather than locally

Fixed it. Changed .addforce to .addrelativeforce

[uncut vapor]

Hey, is there any way to add a tile to a tile palette through script? All I could find was setting a tile in a tilemap

[pine bronze]

hey guys, im trying to make a car with wheel colliders but when i start the game, my wheel colliders move a bit forwards (which they shouldn't), and when i press W to move forward, the wheels move, but the car doesn't move. also the wheels go a bit under the ground

[fresh cosmos]

actually i'll post this in editor instead

[devout solstice]

i’m trying to neaten up my code, i have 4 if’s, so if (name.containsinsensitive(“”)){
wtv = “”
}
so on and so fourth, im checking if the name contains a word and sets wtv to the word if it does, and there’s 4 words, i check each of them, is there a way to do that but more compact then 4 if statements

[knotty sun]

put your 4 words into an Array and then loop over that

[thick terrace]

wordsArray.Any(name.Contains) if you want it even more compact

[shadow laurel]

I've been asleep so sorry it's taken a while to respond. The reason why I believe the problem to be around the coroutine is because the error only occurs when the coroutine should run

[leaden ice]

The stack trace is clearly indicating that this is an error while drawing the inspector aka Editor for your network variable

it shouldn't affect gameplay

[heady iris]

Restarting the editor often sorts this kind of thing out.

[shadow laurel]

Yeah I'll try that when I get on later. The problem with it occurring Is that the script it says is the problem isn't a script I have made or edited

[leaden ice]

Yes, as mentioned, it's the inspector rendering your network variable

it's a bug in Unity's code

[shadow laurel]

Ahh, thanks for the explanation.

[heady iris]

Actually, on this subject.

How should you go about diagnosing that kind of error?

I'm frequently seeing an exception caused by a disposed SerializedProperty. I'm thinking it might be caused by one of my packages.

I have no idea how to track down which property is at fault

[leaden ice]

I don't think there's a good way other than trial and error. Maybe try to put a breakpoint inside NetcodeBehaviourEditor near the error line and see what you can find?

[heady iris]

I wonder if the UI Toolit Debugger could help at all

Sometimes an error creates a very obvious problem in the inspector

like, everything just stops rendering

but this one is subtle

[simple egret]

??????

hahaha

[swift falcon]

[latent latch]

Looking for some ideas how I should implement my tooltip descriptions. So, currently my implementation for data objects all derive for a Storable type such that they include a Name, ID, Sprite (UI purposes), and a Description. This storable type also includes the scriptable object that is in relations to that specific object.

For my abilities, which also inherit from Storable, can be used directly by the player, or through another means like triggers which passively uses the ability. These passives are linked to my Trigger class which also inherits from Storable, such that each Trigger instance has an Ability instance wrapped inside.

Lastly, I've a Mod class (also a Storable type) which depending on the requirements, will or will not be added to the character. This class can contain an instance of Trigger, meaning that if the player meets the criteria, this mod will allow certain abilities to trigger the ability it contains.

So to break it down: Mod instance contrains a Trigger instance, which contains an Ability instance. All of these classes inherit Storable, and thus all have their own descriptions. Now, that's a problem because since I've all these descriptions, I don't know what to prioritize on what to populate my tooltip with. Ideally I'd populate the Mod description and use that, but as I said earlier, abilities are not* strictly used by triggers and can be casted normally. So, if it's contained as a Mod, it should contain a different description than displaying the Ability info.

Maybe the idea is just separate descriptions and just make it an interface. That's one way I guess. As it is, I'd like to minimize the amount of wording I need to do for everything, but I guess it's just too much mixing and matching that I may just need to populate it all manually.

I hate UI stuff

Interestingly too, a lot of games seem to implement sprites for all their objects even if not used. So that's kind of another thing I'm debating keeping as is because it doesn't make sense for some wrappers to be displayed on the UI.

[gaunt garden]

I would recommend making it an interface regardless. Inheriting from a class for this case seems overkill

[hard viper]

is it expensive at all to have an additional trigger collider that touches everything in the game all the time?

[zinc parrot]

So say someone downloads a project of mine, and this project has several options that I have to seperate out with several #defines
Currently, to enable or dissable any one of these, the user has to go to each file that uses the define they are interested in and comment/uncomment it in each file
What is a better/more user friendly way to do this that still allows the #define kind of behavior but can be toggled in a single place easily instead of having to be toggled in 5 seperate files?

[knotty sun]

Project settings

[zinc parrot]

but that seems like a hassel for whoever downloads my tool

[knotty sun]

it's in one place

[spring creek]

Project settings seems like a hassle?

[zinc parrot]

fair

alright ok I will do that then thanks!
just seemed inconvienant, its more convienant than I currently have, but I wanted to see if there was something more I could do

[heady iris]

You can make a custom Editor window to toggle the defines.

[knotty sun]

you could easily write your own Editor script which directly affects the project settings, makes it that little bit more convenient and accurate

[zinc parrot]

OH!
I completely blanked on the fact that an editor script can modify the project settings... thanks!

[void birch]

Can someone tell me if this is wrong and has an error or right (this is a player wasd movement script

[void birch]

using UnityEngine;

public class PlayerController : MonoBehaviour

    float vertical = Input.GetAxis("Vertical");

    // Move the player based on the axis values
    Vector3 movement = new Vector3(horizontal, 0, vertical);
    transform.Translate(movement * speed * Time.deltaTime);

your IDE and unity will tell you if there is an error . . .

[rain minnow]

[rigid island]

if its a button how can be an axis

so probably not

axis gives you float

[acoustic sinew]

That's what I was thinking, in the Docs it shows "Fire1" as a button, so I didn't know if using the name of the axis would work

[feral rain]

just use axis lol

[rigid island]

if its an axis you would just check the float

[acoustic sinew]

What I'm trying to do is figure out is how to add extra deceleration to my player outside of increasing the drag on the rigidbody

[rain minnow]

it returns a bool and states it should only be used with action-like events . . .

[brisk plaza]

Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details

[rigid island]

don't you have a vector2 for inputs? @acoustic sinew

[rain minnow]

it even says to use GetAxis for any kind of movement behaviour . . .

[acoustic sinew]

I'm taking the input from the axis and setting Vector3 value.

[rigid island]

if(inputs == Vector3.zero) if(rb.velocity.magnitude > 0.2f) //add more friction

or something like that

maybe you can even swap physics materials

[acoustic sinew]

Thanks, I'll give something like this a try and see what happens

[unique edge]

Okay this is gonna sound a bit dumb, but I’m trying to create a sliding script in unity3d and I cannot figure out how to even make the character move forward on a button press. I have the WASD and jump movement already set up, but for some reason I can’t figure out how to make the character move forward on a different button

Using a character controller btw

[hybrid turtle]

Hey guys has anyone worked with Qauternions and Euler angles I need some advice… I need to implement a scene where a person can rotate an object along the all permutations of x,y, and z axes and was wondering how difficult this would be

[leaden ice]

What does "along the all permutations of x,y, and z axes" mean?

[hybrid turtle]

Like along xy axis xz, and yz axes

Sorry that was a bit unclear

[cosmic rain]

Along xy means rotating around the z axis, xz - around the y and yz - around the x. Which is totally doable with transform.rotate method.

That's assuming I interpret your "along" correctly

[hybrid turtle]

Yes so it’s just a simple transform.Rotate() it must also be done with a mouse

Like a cursor should be able to rotate it around these axes

[west lotus]

How are you defining your third axis?

[hybrid turtle]

Not sure I haven’t began to conceptualize how to do it other than I’ve read on some forums this ha been done with quaternions and Euler angles

[vague slate]

Is there any way to breakpoint UnityEngine methods? Like Object.Destroy

[vague tundra]

How can I run a script in the editor (not in play mode) with the goal being to make some modification to all objects in my scene that have a specific component?

[hearty sphinx]

how do i make a cinemachine virtual cam follow a rolling ball and not rotate?

these are the current settings

[vague tundra]

@hearty sphinx I have no idea what a cinemachine is...
Do you have to provide a LookAt transform?

[hearty sphinx]

according to tutorials you just need a follow

[vague tundra]

Maybe worth trying quickly just incase?

[hearty sphinx]

it wouldn't work with lookat

same with both set to player

[vague tundra]

@hybrid turtle Have you given any more thought to your issue?
If I'm understanding correctly, you're wanting to rotate on all 3 cardinal axis using your mouse.
An issue the others hinted at was the fact that really your mouse only allows for rotation about 2 cardinal axis, not 3.
(Move mouse up/down for one axis, left/right for another... and nothing for the 3rd axis rotation)
You'd probably have to have some additional input, a toggle of sorts, to allow your, for example, left/right mouse movements to rotate around a different axis when toggled

@vague slate Would setting a breakpoint in your objects OnDestroy method do what you're after?

[vague slate]

yes, did it already 😅

[hearty sphinx]

making the camera follow the ball seems like too much work, how can i add force to the ball relative to the camera?

assuming the camera is fixed, the ball will always go south if i press S

[vague tundra]

If you're using the unity physics engine, you can get a reference to the balls RigidBody and call the AddForce method, with some force value

[hearty sphinx]

    var horizontalAxis = Input.GetAxis("Horizontal");
        var verticalAxis = Input.GetAxis("Vertical");
        var direction=new Vector3(horizontalAxis,0,verticalAxis);
        rg.AddForce(direction * force);

i'm currently using this, but i don't know how i would move it in relation with the camera

[vague tundra]

Please describe how your camera works

[hearty sphinx]

right now i'm just setting it at a fixed position like in the picture

[vague tundra]

Then the ball will always be moving correctly relative to your camera

[hearty sphinx]

oh i didn't think of that

i thought that randomly spawning the ball would change how it moves

and i just need to set the camera correctly

not the other way around

Hey, is there any way to add a tile to a tile palette through script? All I could find was setting a tile in a tilemap

[sudden lantern]

Hello. I have a list with positions and rotations. I need to move the CharacterController around these positions and rotate him. How can I do this?

[prime sinew]

you could start by looking up how to move objects with CharacterController?

even looking at the documentation for CharacterController will get you someplace

[sudden lantern]

I know how to move objects with CC, but I have a list of positions and I need to move an object by these positions with some speed

[prime sinew]

okay, how do you move objects with CC?

[sudden lantern]

Move method and some direction🤔

[prime sinew]

okay

you try looking up "how to move character controller to position unity"

[mellow sigil]

The general algorithm is that you save the first position in the list in a variable as the current target and move towards it. When the CC reaches that target, you change the current target to the next position in the list and so on

It's called "waypoints," it'll get a lot of hits with Google

[formal swift]

Hi, I've been trying to figure this out for literally 24 hours, I'm completely new to Unity and coding and is desperate. Please help me...

I've been trying to follow this tutorial: https://www.youtube.com/watch?v=0T5ei9jN63M

These are my scripts

I made sure patience bar is arranged accordingly in hierarchy

But my health bar just isn't moving, does anyone know why?

According to my debug, the bar is supposedly moving, and the patience percentage is calculating accordingly - but the bar itself just isn't moving

[prime sinew]

any errors

and did you check the localscale of Bar

honestly when it comes to tutorials not working, it's most probable that you missed a step or did not follow exactly

are you sure you're looking at the right Bar

[simple egret]

Quite a bit of shitcode now that I look at it. Using an EventHandler instead of a simple Action (since none of the two parameters are used), usage of transform.Find() where a direct reference would have done the trick, and changing the scale instead of a sprite's fill amount
Are all of CodeMonkey's tutorials like that one? Wouldn't recommend then

[west lotus]

Pretty much codemonkey is hot garbage

[next salmon]

.

[oblique spoke]

Both can be represented similarly, but behaviour tree states have a distinct structure to them and generally come with a common set of control flow states to compose various states. Just looking at something like Behaviour Planner and the Mecanim Animator should illustrate some of the differences.

[next salmon]

Which do you think is more suited for the ai of a soldier npc using guns?

Im looking to get something similar to the ai of half life 2 where soldiers can take cover, throw grenades, reloade, do melee attacks and etc.

[rigid island]

there is no set answer for this

[next salmon]

So both work fine then?

[hexed pecan]

Behaviour trees tend to be more flexible. But I can't recommend any tools. Im making my own and its a rabbit hole

[rigid island]

Behaviour trees are great, just very diffcult because unity doesn't have a built in tool

[next salmon]

Thanks for the advice yall. I'll take a deeper look into behavior trees. See how it works out.

[hard viper]

I’m making a generic class class<T>, but I need to enforce that T has == defined. How do I do that?

[leaden ice]

can you not just use .Equals?

and if that's not enough then where T : IEquatable<T> to ensure it implements IEquatable

[hard viper]

ty

[simple egret]

For completeness, once Unity switches to the CoreCLR, you will be able to constrain the type to IEqualityOperators<TSelf, TOther, TResult>

Which uses the static abstract members in interfaces features, essentially allowing you to force a class to implement a static interface member

[formal swift]

I finally solved it

The bar was there the whole time - somewhat functional too, but for some reason, transform/position was acting weird, making the bar somewhere far off-screen. I only finally saw it when I was lowkey bashing my mouse and zoomed far out only to find the damn bar instantiating in a weird place.

I changed out the "prefab transform" portion of the tutorial and it finally started functioning from there ;-; god dang a day gone over smt so stupid.

[formal swift]

Ohmigosh, fill amount 🫥 how do I do that? That sounds way better than scale. I've been wanting to give the bar a proper asset but am stuck with flat colours cuz all I've found uses "scale" which squishes/stretches art works. Will fill amount be able to help w that?

[formal swift]

Imma....hella take note of that from now on..

[prime sinew]

yes

you're probably better off using Unity Learn

[simple egret]

You need an Image component, assign a valid Sprite to it, set the Sprite Mode to Filled, and tweak the fillAmount property from the code

If the bar is a solid color, a 1x1px white image will do the trick, you can change the color in the Image component

[formal swift]

Will this work for game object? or is this for UI element?

[fervent furnace]

ui, image is ui

[simple egret]

Objects with the Image component

[fervent furnace]

you can use gameobject with sprite renderer to achieve health bar but slight difficult (not much, just tune the scale and position)

[formal swift]

Oh yeah, image is only for UI

I followed crazy monkey's cuz i specifcally needed the bar to be a game object

In that context, is there any better way to create a health bar from just game objects?

[leaden ice]

UI is made of GameObjects

[rain junco]

I need some help. Iam making a tower defense game in 3d and i have 2 towers with an example height of 1.5 and 3. I have some cubes with a given layer to place the towers at. Now i want the towers no matter of their height to be placed on top of the cube with its button exactly on top. So basicly the 1.5 high tower being .75 above the cube and the 3 high one 1.5 above. I hope my problem is understandable heres my code iam changing the system rn so some parts are confusing. https://paste.ofcode.org/3azFEDEqDX5zHY6FUT2d6vn

[formal swift]

Sorry, I meant without using UI Canvas

[leaden ice]

Maybe instead of saying what you don't want it to be, say what you do want it to be

explain the effect you want

[formal swift]

Health Bar that doesn't use UICanvas

[leaden ice]

why do you have a limitation of it not using a canvas?

what are you trying to do with it

[formal swift]

I'm attaching the "patience bar" to a customer prefab.

[leaden ice]

you know you can use world space or screen space - camera canvases for this?

[formal swift]

I know pretty much ntg

I'm currently doing it this way cuz the bubble will automatically disappear w the customer when they "leave"

[leaden ice]

you can do that just fine with a world space canvas

[formal swift]

I just don't know how tbh. My first version was using a canvas, couldn't wrap my head around it so I switched to this

[leaden ice]

I'm telling you the canvas is the better / easier way

what part are you confused about doing?

Make a world space canvas

put your image etc on it

make it a child of the player

[formal swift]

My customer characters are prefabs, when I put the canvas into the prefab, everything about the bar stopped working

[leaden ice]

so debug that issue

there's no reason it can't be part of the prefab

[formal swift]

The more I edited the script, the weirder it got - specifcally "2D instance null" or smt that messes w the gameplay itself. - even though the script I'm editing has ntg to do w that portion of the game

[leaden ice]

sounds like basic scripting errors

[formal swift]

I spent a whole day trying to

[leaden ice]

¯_(ツ)_/¯

it's not a complicated setup

[formal swift]

Maybe I'll try again next time, but not now

[leaden ice]

That's my recommendation for the best/easiest way to do this

If you don't want to try it, that's fine

[formal swift]

It is to me, never touched scripting - never touched unity

[leaden ice]

right so

some other solution that is even worse is going to be even harder for you

maybe you are jumping too far ahead, and should focus on the basics for now

[formal swift]

What I have is kinda working

was just asking if there was a better way for future reference

[leaden ice]

it sounds like you haven't yet mastered the basics of working with prefabs, working with script references etc.

[formal swift]

It's not like I can change it now, my stuff's due monday

[leaden ice]

you should focus on that

[formal swift]

Defiitely

[leaden ice]

once you master the basics, this stuff will become easy

[toxic helm]

;-;

[rigid island]

you need some sort of storing/data base system

[dusk apex]

Either implement saving and loading between scenes or don't let the managed data be destroyed

[toxic helm]

and how do me do that?

[rigid island]

ideally through a file saved

or like Dalphat mention, keep it in memory and dont destroy objects from prev scene

you could potentially get fancy and use something like SQLite to make a small db file

[hard viper]

Equals was a good call, praetor. ty

[calm delta]

void FixedUpdate()
    {
        Vector2 inputDirection = inputValue.normalized;

        smoothedInput = Vector2.SmoothDamp(smoothedInput, inputDirection, ref smoothedInputVelocity, 0.1f);

        velocityX = Mathf.Clamp(velocityX + inputDirection.x * basePlayerSpeed / 6, -(basePlayerSpeed + speedLimitAddition.x), basePlayerSpeed + speedLimitAddition.x);
        velocityY = Mathf.Clamp(velocityY + inputDirection.y * basePlayerSpeed / 6, -(basePlayerSpeed + speedLimitAddition.y), basePlayerSpeed + speedLimitAddition.y);
        velocityX -= velocityX * 0.1f;
        velocityY -= velocityY * 0.1f;

        speedLimitAddition *= speedLimitAdditionDecay;

        rb.velocity = new Vector2(velocityX, velocityY);
    }

so i have this code for my movement, it is quite messy but it serves its purpose and has the functionality i need, there's only 1 problem, going diagonally is faster
i have no clue how to solve it in this instance, anyone got ideas?

[acoustic sinew]

I'm currently getting a type mismatch when I try dropping my player into the GameObject spot for a script. In the script it is set to be a GameObject, so I'm unsure why it is throwing this error

public Rigidbody bulletRB;
private void Start()
{
    playerRB = GetComponent<GameObject>();
    bulletRB = GetComponent<Rigidbody>();

    bulletRB.AddForce(playerRB.GetComponent<Rigidbody>().velocity.normalized * 100, ForceMode.Impulse);
}```

[rigid island]

is this a prefab?

or did you switch types for playerRB in the script at some point?

[acoustic sinew]

The player is a prefab

[calm delta]

use gameObject instead of trying to do getcomponent for it

[rigid island]

uhh what about this object ?
screenshot inspector for this script

this also makes no sense

   playerRB = GetComponent<GameObject>();
    bulletRB = GetComponent<Rigidbody>();```

[acoustic sinew]

That is the screenshot from the inspector for the script.

[rigid island]

its cropped. show the full object in context

[uncut vapor]

Hey, is there any way to add a tile to a tile palette through script? All I could find was setting a tile in a tilemap

[rigid island]

probably an editor script

[acoustic sinew]

Which object? The object the script is attached to or the Player Object?

[uncut vapor]

well that doesn't really help

[rigid island]

the object we've beeen talking about this whole time

[knotty sun]

https://forum.unity.com/threads/tilepalette-scripting-api.749465/

[rigid island]

damm

beat me to it was linking same thing

🦥

[uncut vapor]

Thank you

[rigid island]

no the object this script is on

[knotty sun]

google is a wonderful tool

[rigid island]

this is also a prefab yes?

[acoustic sinew]

Yes

[uncut vapor]

I really don't know how y'all find everything, I did try googling it and found nothing

[rigid island]

so you're trying to reference a Player in the scene

not gonna happen

[knotty sun]

really difficult. Unity Tile Palette API

wait, Player is a GameObject and a Prefab, this is the gameobject

[acoustic sinew]

So then how would I get the rigidbody from the player in the scene to use his momentum for projectile that's being fired?

[rigid island]

who instantiate the bullet ?

[acoustic sinew]

The player

[rigid island]

so the player can pass itself to the bullet

https://unity.huh.how/programming/references/prefabs-referencing-components

[acoustic sinew]

Thanks

Well I guess it's more of the gun instantiates the bullet, but the gun is a prefab that is attached to the player. Still probably works the same though?

[rigid island]

yes as long as it has that reference, it can pass it through method paramater when instantiating bullet

[swift falcon]

This is weird, Unity showing inaccessible (private) serializefields from the parent class in subclasses in the inspector, and complaining that I'm not setting these unable-to-be-set fields.

Assuming I just remove the serializefield attributes and set the components in Awake ? anyone run into this before

[potent topaz]

someone know why this line makes my targets (red circles here) have such a offset here ?

targetPositions[i] = transform.TransformPoint(_legs[i].defaultPosition);

defaultPosition being the localPos of my legs

[dusk apex]

Show the code

[swift falcon]

Anyways, I'm experimenting with a new structure to better segregate client vs server functionality relating to Mirror as doing it all within a single Player class was becoming less maintainable.

[south agate]

I think this is more algebra than coding, but how can I detect the area under an object? Like a vehicle

[hard viper]

I have a complex composite collider2D. I want to find all colliders in the scene (subject to a layer mask/contact filter) that would overlap with this collider if it were translated by a certain vector. What is the right way to do this?

I feel like there is just one specific physics method I need for this, but there are so many to choose from

should I use OverlapCollider? like, translate collider, call overlap collider, then translate it back?

[spare dove]

Does anyone have any clever math trick to calculate a cone shape on a 2D grid? Like dnd's cone stuff, that is more clever than me just predefining shapes

[hearty sphinx]

is it viable to only use the inspector to just inspect, and use c# for everything else including adding components and prefabs? would it hurt performance if i set up the components and prefabs in awake()/code ?

[lean sail]

Calculate what of a cone shape? What are you trying to do with this

[swift falcon]

it is not required to pass in the references via serializedfields. setting the references in awake seems more scalable in larger projects. there is no performance difference in doing this in awake vs inspector.

[heady iris]

Use GetComponent in Awake if there is no ambiguity about where the component comes from.

Sometimes I'll do that if the field isn't already assigned

so that it "defaults" to looking for a sibling component

[lean sail]

It's certainly something you could do. Of course itll affect performance if you have possibly 100s of components being added to objects all at once in awake, although itll just happen once.
I dont see a single benefit to doing this, other than trying to overdo some design pattern.

And itll make some references very annoying to setup

[hearty sphinx]

i want to do that so i don't have to manage both the ui and the code side, i think it would also lessen nullreference stuff

is using GetComponent faster than AddComponent?

[heady iris]

two unrelated concepts

GetComponent retrieves an existing component.

I presume it's faster beacuse it isn't creating a new component.

[heady iris]

I do it whenever I notice that I'm not making complex decisions

X always has Y, and Y is always configured in the same way

[spare dove]

My game is grid based, using Vector2Ints to define squares on the playing field. I would like to come up with a clever way to give a function a position to start from say 2,4 and then a direction and a length and for it to return the squares that would constitute a cone shape in that direction from that position

[heady iris]

the spatial audio system I built for one game automatically generates the AudioSource and the various audio filters

because I always did the same thing every time

I did have to add various knobs and levers to the spatial audio component to let me properly configure the audio source

[hearty sphinx]

don't you get confused between having to manage both ui and code? you'd get the component in the code anyway so why not do everything in code?

[heady iris]

you make design decisions in the scene view.

For example, a boss enemy has a move that triggers when the player stands in a danger zone for too long

[swift falcon]

to each their own I suppose, but managing references in UI seems the greater lift and having to repopulate anytime a referenced name changes, versus having it just always keep the known reference upon name changes. in a large project with lots of prefabs, seems more time consuming to always be managing in inspector.

[heady iris]

the code doesn't decide where that danger zone is

it also doesn't decide which danger zone it's using

that is configured in the inspector

[lean sail]

They said it in a way like always doing it through script. I imagine itd be very tedious if you had 2 buttons and 2 doors and wanted to hook them up compared to just dragging it in inspector

[heady iris]

I could add some hideously brittle Find call to locate the danger zone, sure

but that sounds awful

[hearty sphinx]

it would be nice if the inspector automatically added the c# code too, but maybe that would make it cluttered for some people, especially if it's code they didn't write

[heady iris]

wot

[lean sail]

Is this 2D? Because you could just do it based on triangle instead of cone which would be way easier

[heady iris]

i definitely would not want to see my entire source file inserted into the inspector

that sounds very strange.

[hearty sphinx]

like adding collider in the ui would automatically add AddComponent in awake

[heady iris]

oh, I see

that also sounds very odd, though

you'd be trying to auto-generate code that accomplishes the same thing as just assigning the reference

that code would only work if every instance of your component had a collider as a sibling

and it would malfunction if you had multiple colliders

and it wouldn't be sufficient if the colliders could be on another object

[lean sail]

Yea theres really no point in that, and you would have a major unreadable mess when you have this happening on 100 objects for example

[hearty sphinx]

so basically you have to know when to balance it out?

[heady iris]

yes

[heady iris]

^

[lean sail]

This might just be trying to adhere to some pattern toooo much. Using your inspector for inspecting only is kinda not smart

[heady iris]

I've deliberately moved some stuff out of code and into the inspector

for example: boss move patterns

I wrote a reasonably elaborate system so that I can make a list of "steps" entirely in the inspector

now I can tweak behavior entirely graphically, without modifying the code

if I want to add a slight variation of an existing move sequence, I can just make a copy of the data

instead of writing an entirely new script

[lean sail]

There is a point I guess where you could do this without really using inspector, but you would just be creating the equivalent of any web game

Once you have anything more than flappy bird, theres no point

[lean sail]

Do you define the steps in code then just plug them in? Im kinda brainstorming how I want to code a similar thing

[hearty sphinx]

this reminded me a bit of someone making a game playable in the inspector

[hearty sphinx]

how does version control work with the inspector?

like in a team, isn't it important to document inspector/prefab changes?

[heady iris]

you would explain that in the commit message, yes

[heady iris]

so my game is built entirely around "entity states", which represent...states an entity can be in. Each entity can have many small state machines.

A "scheme" is a series of SchemeStep objects (it's a [SerializeReference]'d List<SchemeStep>).

The most important kind of scheme is the SchemeStateStep, which has a List<EntityState>

[hearty sphinx]

can you show a screenshot of those steps in the inspector if you have unity open now?

[heady iris]

When it's entered, it tries to enter the first state in the list. It might wait for the state to complete, or it might do several in parallel

[lean sail]

Ah you've lost me, I'll probably just hardcode most things lol

[heady iris]

To keep track of when things are done, I pass "completion tokens" around. The token is passed from state to state until a "sink" is reached, which eats the token. Until the token has zero active states associated with it, the token is alive

I think it might actually be working

[hearty sphinx]

i also don't know why use serializedfield instead of public/getter and setter, maybe to adhere to patterns?

[heady iris]

you mean [SerializeField] instead of a public field?

[hearty sphinx]

yes

[heady iris]

This is a basic one. Note that each state is actually a "state reference". Each kind of state has its own configuration options, so I have to include that alongside the actual entity state

more `[SerializeReference]

[heady iris]

Oftentimes, you need to be able to configure fields, but you don't need to let every class see them

[spare dove]

2D! How would it be easier with a triangle?

[heady iris]

A cone that's aligned to the 2D plane looks like a triangle

[heady iris]

for example: I have a class whose sole job is to reset the game if you push the "R" key

[SerializeField] InputActionReference restartAction;

There's no reason to expose that field to other classes.

[hearty sphinx]

this looks like it would be easier to code but it's convenient if you have a ui for it

[heady iris]

It's generally easier to code it once, yeah

It's also easier to code it a few times. You don't have to solve the entire problem of "how do I perform a series of attacks correctly?"

You just have to solve part of it each time.

I've run into lots of issues along the way. For example, the scheme needs to be aborted if something unexpected happens (e.g. the boss gets stunned)

or if the boss grabs the player, it shouldn't continue trying to attack; it should smoothly transition into another phase

[swift falcon]

Encapsulation is the relevant OOP concept to look into here. private/protected are both useful, and public really allows any class to modify the values, which is sometimes undesirable and how your game can become easily cheatable.

[heady iris]

I would not say that public fields make it easy to cheat

Access modifiers are strictly there to help the programmer write more reliable code.

If the player is capable of writing and executing arbitrary code, they're going to be able to cheat

[hearty sphinx]

does plan scheme state derive from monobehavior or scriptable object?

[heady iris]

Neither. These are all plain classes.

    [SerializeReference]
    public List<SchemeStep> steps;

[hearty sphinx]

plain classes' data can be saved in prefabs?

[heady iris]

Indeed. You just need to make the class serializable.

Note that you won't be able to drag in a reference to your class -- it is not a UnityEngine.Object

It'll just show up in the inspector.

With [SerializeReference], you can use polymorphism. SchemeStep is an abstract class that I have several classes derived from.

Note that there is no built-in UI for [SerializeReference] fields. You need a third-party package to get them into the inspector

It lets me pick from a variety of options.

[lean sail]

That's pretty cool, something like this is what I wanted to code as well

[heady iris]

I think it might actually be working

[hearty sphinx]

that's nice, i'm still getting used to FSMs, even in c++/embedded stuff

[heady iris]

It was a solid week of really boring slogging lol

and I'm still not completely happy with it

[hearty sphinx]

but it must have felt nice when it worked

oh

[heady iris]

it does feel nice :p

My state machines are a bit weird. They have almost no rules for when you can switch states.

I'm still figuring out where, exactly, those decisions have to be made

Game design hard

It's a lot easier when you just hardcode some logic

which is absolutely where I started

You can start seeing patterns after a while.

[swift falcon]

multiplayer game design hard ++. deep into the mirror rabbit hole this week, and realizing it changes every aspect of my existing concept

[heady iris]

dies

I'm doing LOCAL multiplayer in this game

take it or leave it

[lean sail]

Yea I jumped into multiplayer now I am abandoning the game and making a singleplayer combat game

[swift falcon]

well, webgl sucks, and websockets, bleh, this is what i've learnt this week

[heady iris]

i should get back to work now

% git status | grep '.cs' | wc -l
      19

i am halfway through rewriting way too much stuff at once

one thing that I really like about using a statically-typed language like C# is that I can just fix errors until the game compiles again

and it's startlingly likely that everything will work

i used to write web games in plain JS and it was miserable

[hearty sphinx]

when i watched a video on how to make multiplayer i got scared lol, you have to manually assign which variables are known and sent to the server

[heady iris]

you have to think about who "owns" what

and how to handle disagreements about game state

I've prototyped one game and that's it

[hearty sphinx]

just ban anyone but the host ez

[swift falcon]

yea, this is the path i'm down in the latest experiment.
instead of my monolithic player.cs class
i'm onto player.cs + playerclient.cs + playerserver.cs to keep the various client/server stuff segregated. got the concept initially working tho

[hearty sphinx]

implementing rollback must be a nightmare

[swift falcon]

my build is dedicated server then all players are clients, never hosts

[heady iris]

i haven't tried to do any kind of prediction or reconciliation yet

[swift falcon]

apparently the next mirror version will have some better stuff for prediction so looking fwd to seeing what they provide

[hearty sphinx]

and here i am making a ball collecting spinning cubes as my first class homework

[lean sail]

Even something like this may end up chaotic. Separating your client/server stuff is fine but it's really a lot of work and even the ngo team has said it's not needed in like 98% of games

[swift falcon]

i don't discount it might be overkill and unsure how it scales into the full game yet. running an experimental concept as i'm 1 week new to mirror

[hearty sphinx]

it feels like adding network violates some programming principles

like a movement script should only do movement stuff, not multiplayer related stuff

[lean sail]

Well you definitely will have to break some rules for networking to work properly. Most "programming principles" are just random things web dev people follow. The people who have too much time to think about architecture in the first place

[swift falcon]

the key for optimization is really reducing as much network traffic as possible and not syncing all things and hammering low ping clients. idk, still figuring out the right balance here. ultimately, my plan would be dedicated server on cloud then all remote players being clients, not hosts

i'll just say. dont make a game, then make it multiplayer after. that is a world of pain lol

[wary mortar]

Good afternoon. I am trying to implement mobile input, but Im having issues: I am using a class derived from OnScreenControl for the inputs. I wan to move the player with a joystick and move the camera whenever the player press somewhere in the screen. The problem is: when I press the joystick, the camera zone - which is supposed to be behind this button - also gets triggered and the camera also moves.
Is there a way to stop this from happening?

[leaden ice]

Use the event system for your camera control too

E.g. a big invisible UI element behind the onscreen control

With OnDrag etc

Or PointerDown

[wary mortar]

I'm using it, for the camera control. Now I need to make the joystick in front of the camera and dont press the camera button - which is the screen- when I press the joystick

[hearty sphinx]

now i'm imagining some game devs joining a morning meeting and then the boss says "we decided to add multiplayer" 3 years into development

then again some modders made multiplayer breath of the wild mods

https://github.com/HouraiTeahouse/Backroll this is apparently a port of GGPO/rollback netcode for unity, might make it easier/harder, but there's no documentation

there's even a ringbuffer class which i didn't know is possible/what you would use it for with c#

[zinc parrot]

hey so is there a way to do this so that I dont have to explicitely pass the stride as a function argument and have the function able to find out the stride of the input data by itself?

[leaden ice]

Make an interface for your struct and have it return its own size

[zinc parrot]

ooooo didnt know you could do that! time to figure out how

[zinc parrot]

wait cant I do this?
int stride = System.Runtime.InteropServices.Marshal.SizeOf(typeof(T));
Whats the downside of this?

[heady iris]

That would give you the size of Type

[zinc parrot]

oh...

[leaden ice]

Have you tried it? Does it work? IDK it might

[heady iris]

    unsafe void Florp<T>() where T : unmanaged
    {
        int x = sizeof(T);
    }

This doesn't give any compiler errors for me.

I get warned that T might be managed if I only constrain T to be struct

System.Runtime.InteropServices.Marshal.SizeOf takes an instance and gives you the size of it. I guess you could do...

System.Runtime.InteropServices.Marshal.SizeOf<T>(default);

[zinc parrot]

it seems to work

[heady iris]

oh wait, duh

https://learn.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.marshal.sizeof?view=net-7.0#system-runtime-interopservices-marshal-sizeof-1

System.Runtime.InteropService.Marshal.SizeOf<T>() works

The non-generic version is there so you can get the size of an object without any clue what its type is

[zinc parrot]

sweet
is there any real downside or is it fine?

[heady iris]

The sizeof operator returns a number of bytes that would be allocated by the common language runtime in managed memory. For struct types, that value includes any padding, as the preceding example demonstrates. The result of the sizeof operator might differ from the result of the Marshal.SizeOf method, which returns the size of a type in unmanaged memory.

It sounds like you need the Marshal.SizeOf method.

You want the unmanaged size.

never knew that. neat.

[zinc parrot]

aint that what this is?

[heady iris]

That's asking it how big a Type is

SizeOf<T>() will do what you want.

[zinc parrot]

oooooo

[heady iris]

oh, wait, I was mistaken. It has an overload.

https://learn.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.marshal.sizeof?view=net-7.0#system-runtime-interopservices-marshal-sizeof(system-type)

It has two different versions that take a parameter

one takes object; one takes Type

So that would, indeed, work.

I saw the object one first and missed the Type one.

[zinc parrot]

I switched to the SizeOf<T>()

as long as theres no major downsides or performance penalty or weird memory things im happy

[graceful wren]

guys, what is the difference between vector3[ , ] x; and vector3[ ] x;

[somber nacelle]

the first is a 2 dimensional array of Vector3, the second is just a 1 dimensional array of Vector3

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays#multidimensional-arrays

[graceful wren]

so why not write as vector[ ][ ] x;

[leaden ice]

because that's a totally different thing

[somber nacelle]

because that's an array of arrays of Vector3. it's not quite the same thing as a 2 dimensional array

[graceful wren]

oooh, ok thanks for the help @somber nacelle

[heady iris]

A multi-dimensional array is one huge array and must have consistent sizes in each dimension

An array of arrays is just a small array (that points to other arrays), and can have varying sizes

[steady moat]

Isnt the term jagged array ?

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays#jagged-arrays

[somber nacelle]

yes, but it's still an array of arrays

[acoustic sinew]

Accroding to the docs Rigidbody.velocity should find the linear velocity of the rigidbody. However it seems to be taking the angular velocity and adding it to the object that is being instantiated

[somber nacelle]

assigning to the velocity property of a rigidbody has nothing to do with its angular velocity. you need to provide more context as to what is happening to determine where your issue lies

though at a guess, i'd say the instantiated object is probably colliding with some other object (or depenetrating from another object if instantiated inside of it)

[spring creek]

Hmm, there IS an angularVelocity
https://docs.unity3d.com/ScriptReference/Rigidbody-angularVelocity.html

But yeah, velocity is not it

[acoustic sinew]

{
    if (Input.GetButtonDown("Fire1"))
    {
        GameObject firedBullet = Instantiate(bullet, muzzel.transform);
        firedBullet.GetComponent<Rigidbody>().AddRelativeForce(player.GetComponent<Rigidbody>().velocity + new Vector3(0, bulletVelocity, 0), ForceMode.VelocityChange);
    }
}```
Here is the code that I am referencing. When I spin the player object it seems to be taking the angular velocity of the player and adding it to the bullet. Because when I click "Fire" as the player is spinning, the bullet just falls in front of the player. However, when the player is standing still or moving the bullet fires off into the distance

[somber nacelle]

you make it a child of the muzzel object. which means it's transform affects the child object's transform

[leaden ice]

sounds like the player is colliding with the bullet

[somber nacelle]

but also yeah, could be colliding with the player

[leaden ice]

also you're adding the player's world space velocity to the bullet in Relative mode

meaning you're treating a world space vector as a local vector, which isn't correct

[acoustic sinew]

The bullet gets destroyed anytime anytime it collides with anything, and it's not being destroyed until it hits the ground or another object

[acoustic sinew]

IW as normalizing it, but removed it to see if it made a difference, and it didn't

[leaden ice]

normalizing it won't fix it

nor does it make any sense here at all

[acoustic sinew]

I thought "normalized" made it local space instead of world space

[leaden ice]

this is what I would expect here:

bulletRB.velocity = playerRb.velocity;
bulletRB.AddRelativeForce(Vector3.up * bulletVelocity, ForceMode.VelocityChange);```

[leaden ice]

you thought incorrectly

no idea where you got that idea from

normalizing a vector sets its length aka magnitude to 1

[acoustic sinew]

O

[acoustic sinew]

I don't want the bullet velocity to be equal to the player velocity. I want the player velocity to be added to the bullet velocity, so that if the player is moving to the right the bullet doesn't just go straight, but it goes straight and to the right

[leaden ice]

that's what my code does

[spring creek]

It sets it to the player, then adds more on top. Which, of course, adds the player velocity to the bullet velocity

[acoustic sinew]

This still causes the samething to happen

[leaden ice]

then again i think it's due to a collision with the player

it's also not clear that you are instantiating the bullet with the correct rotation

you seem to be making it a child of the muzzle (why?)
Normally i'd expect you to simply spawn it with the muzzle's position and rotation

not as a child

Instantiate(bullet, muzzel.position, muzzel.rotation);```

[hard viper]

is there a way to make 1 specific colliders ignore forces from another specific collider?

I still want collision callbacks, and collider A to still send force to collider B, but I want to conditionally stop B from sending force to A (And not just disabling for the whole layer)

[leaden ice]

https://docs.unity3d.com/ScriptReference/Physics.IgnoreCollision.html

[hard viper]

doesn’t that also block callbacks?

[leaden ice]

yes it makes them ignore each other

what kind of callbacks are you expecting

if there's no collision, there's no OnCollisionEnter

if you want trigger callbacks, use trigger colliders

[acoustic sinew]

I get an error say that "GameObject doesn't contain a definition for rotation" And I'm not trying specifically create it as a child of muzzle

[leaden ice]

.transform.rotation
Your old code was specifically making it a child and nothing else

[hard viper]

player/enemy is on moving block. Objects enter/exit reference frame using collision callbacks in a referenceFrameHandler script. Block can only be pushed by things not in its reference frame.

i need to be able to get the OnCollisionExit callback to know I’m no longer in the reference frame

[leaden ice]

I'm not really following

sounds complicated

SOunds like the reference frame stuff can be handled by separate trigger colliders possibly

[hard viper]

Mario can push block.
Mario can ride moving block without falling off.
If Mario is riding a weirdly shaped block (like an L block), he should not be able to push the L block while riding it to propell it

make sense?

i handle with collision callbacks for multiple reasons I would rather not get into

alternatively, if I could listen to a message that a specific collider is receiving force from another specific collider, if I could potentially receive that and modify the force before it is applied, that would help me with several different problems

[swift falcon]

Does anyone have a script for a 2d.mobile game that lets you move side to side

[finite igloo]

This got it working, thanks. But the weird thing is I had to change the .up to .right to get it to go forward lol

[solemn wren]

How would I increase an integer value variable gradually over time, not using a coroutine, and not using floating point numbers?

[spring creek]

Without either? Why.
I dunno without using a float SOMEWHERE. I guess you could use Time.realtimeSinceStartup and casting it to an int and checking it against a preset wait time plus that realtime cached at start...

But... that still uses a float

[knotty sun]

could use DateTime.Ticks but thats a long not an int

[solemn wren]

@spring creek A. im already using an int so i don't want to change it B. Coroutines are taxing in a update loop

[spring creek]

A) doesn't make sense at all. Casting exists. What would you even need to change?
B) what!?

[somber nacelle]

lol well you already have your code so why bother changing it to do something else

[solemn wren]

@spring creek I'm using it for a slider (which can be used for floats by I don't want to, i want clean whole numbers) *a read only slider

[somber nacelle]

well you use a float for just your timer then

but also i don't see why you need whole numbers for your slider

[solemn wren]

I dont need whole numbers i want whole numbers

[somber nacelle]

why

[solemn wren]

@somber nacelle because I do (fixed it)

[spring creek]

Then cast it to whole numbers....

[somber nacelle]

this is an english only server, mate. but that's also a stupid reason. if you cannot come up with a legitimate reason and you just want to shoot down everyone's valid suggestions just because you want integers for literally no reason other than that you just want them, then why even bother trying to get help?

[spring creek]

Bottom line, you're gonna need floating point somewhere, if not only for time, ticks, deltaTime, or something else related to the time passing

Just. Cast. It. Back. You only need it for the time, you can show the player whole numbers no problem

[somber nacelle]

what are the values of min and maxVariablility in the inspector?

[haughty harbor]

variability in the velocity, I want to spawn the alien with a randomized magnitude of velocity within that specific range

[somber nacelle]

what are the values of those two variables in the inspector

[haughty harbor]

oh 💀

I didn't see that

lmfao

[somber nacelle]

there you go, they are only positive. so positive along the X axis is to the right

public class AlienMovement : MonoBehaviour

    public float moveSpeed = 1.0f;
    public Rigidbody2D rb;
    public float maxVariability = 4.0f;

    private Camera camera1;

    private void Start()
    {
        camera1 = Camera.main;

        // Generate a random variability within the specified range
        float variability = Random.Range(minVariability, maxVariability);

        // Set the velocity based on variability
        rb.velocity = new Vector2(variability, 0) * moveSpeed;
    }
    private void Update()
    {
        reverseVelocity();
    }
    private void reverseVelocity()
    {
        Vector2 screenPosition = camera1.WorldToScreenPoint(transform.position);
        if ((screenPosition.x < screenBorder) || (screenPosition.x > camera1.pixelWidth - screenBorder))
        {
            Debug.Log("HIT THE BORDER");
            rb.velocity = new Vector2(-rb.velocity.x, 0);
            
        }
    }
}

The reverseVelocity method seems to work partially. The alien would sometimes glitch near the border of the screen. I'm not too sure why

[patent hound]

i feel like i'm taking crazy pills, why is
playerVelocity.y = Mathf.Sqrt(jumpHeight * -3.0f * gravity);
setting playerVelocity.y to NaN?

[quartz folio]

There is no sqrt of a negative number

[patent hound]

omg

[quartz folio]

Negate it after the sqrt

[patent hound]

gravity is set to 9.8 not -9.8

[quartz folio]

Or that

[patent hound]

so -3 is making it a negative number i'm being silly

thank you lol i have been running circles around that never considered negative numbers lol i was even looking at the doc for mathf 🤦‍♂️

[haughty harbor]

maybe a visual of it "glitching" helps :/. Console shows "HIT THE BORDER" multiple times when the alien only hits it once

[leaden ice]

You should run reverseVelocity in FixedUpdate instead of Update
And use rb.position not transform.position

[dense cypress]

hello friends. i am trying to sync indices of a List of objects and a sphere array[] from the CullingGroup API. i can remove elements from the list, but i cant remove elements the same way from the array. so as elements are being added and removed at random orders in the List, the array index doesnt stay in sequence to the object index, i cant seem to wrap my head around keeping them in tandem. im trying to make it dynamically adaptable without breaking the order. any ideas would be appreciated.

[fervent furnace]

idk what is culling group, is the remove operation on list (or array) is done by the culling group or yourself?

[west lotus]

If yoy are working with culling groups I suggest you check out this free package https://github.com/mackysoft/Vision

[dense cypress]

thanks ive got this one on my tabs already but i need to dynamically update the list and array of spheres because the game is procedural gen

static usages work for me already

lets say i remove objects from the List, at slot [2], so then i have 1, 3, 4 etc. well since its a List, the order moves down to compensate. but the cullinggroups takes an array[] of spheres, so the array itself wont move down in order which means theres desync between the indexes

problem is that the order of which objects are added or removed from the list is not pre-determined and can occur in any order

ive tried other things such as dictionaries, structs etc. to no avail yet

i guess the problem stems from adding spheres to the objects incrementally, for every object initially it gets the same sphere index as the list index. but this works only in a static setting

[fervent furnace]

list is array, as long as crud is done by you then you can control the array as list, idk if you manually remove something from array will affect anything of culling group

[dense cypress]

i think u can only clear an array entry by nulling it right

it wont shift down in index

when u remove an element from a list, the index is reduced by 1 all the elements above it move down

[west lotus]

Iirc vision supports adding a object to the vis arrays when it is instantiated if it has the right component. Now if you want to do it yourself I dont think a list will cut it. You need to have essentially 3 arrays. One for your objects, the sphere array and one to track if a slot in the objects array is free or not. Naturally you want to pre-allocate all 3 arrays to be the same size and that size would be your maximum expected amount of objects

[dense cypress]

i tried 3 arrays as well but maybe i didnt nail it

guess i will start there

if anyone has any more ideas please mention me, and thanks @west lotus ❤️

[rain junco]

I need some help. Iam making a tower defense game in 3d and i have 2 towers with an example height of 1.5 and 3. I have some cubes with a given layer to place the towers at. Now i want the towers no matter of their height to be placed on top of the cube with its button exactly on top. So basicly the 1.5 high tower being .75 above the cube and the 3 high one 1.5 above. I hope my problem is understandable heres my code iam changing the system rn so some parts are confusing. https://paste.ofcode.org/3azFEDEqDX5zHY6FUT2d6vn

[fervent furnace]

so what is the problem? you cant get the height of the box and place the tower on it?

[swift falcon]

Guys I'm working on a builder and I use triggers to detect if build placement is valid by tracking how many things we've collided with.

Issue is that when I am erasing it breaks it because the "OnTriggerExit" isn't called and I'm wondering about how I should approach deleting to resolve this?

Maybe I could attach a script to objects when I collide with them that has an "OnDestroy" event, so if I delete an object it can tell the collision handler that it's no longer blocking it

[prisma junco]

what do i do when i lost date
how can i get it back

this is a code channel, not a code question

[prisma junco]

what?

so where do i go?

[knotty sun]

where you first posted #💻┃unity-talk

[oblique spoke]

Alternative way would be to collect them to a list on the trigger object and loop through them in Update to see if they have become Unity null.

[swift falcon]

Yeh that'd be a fair way and maybe a cleaner way.. Slightly less efficient but not to a point that it should matter

Thanks, I'll consider it

Ok, sorry

[short osprey]

Yo, i'm following along a tutorial and wrote this.

public class ObjectHit : MonoBehaviour
{
    private void OnCollisionEnter(Collision other)
    {
        Debug.Log("Hit");
        GetComponent<MeshRenderer>().material.color = Color.red;
    }
}

The script works for them but not for me. The script is attached to what should be turning red. I feel like i'm missing something super obvious but I can't figure it out...

I did find it weird he calls GetComponent without specific object reference but ig its inherited throgh MonoBehaviour

The method doesn't get triggered at all which leaves me to think the issue lies outside the code, but as i said, its attached to the correct GameObject and it has a BoxCollider component

[simple egret]

For OnCollisionEnter, you need both objects to have a non-trigger collider, and at least one rigidbody

And yes, you can call GetComponent like that, it's inherited from MonoBehaviour

[short osprey]

both of those conditions are met

[simple egret]

3D game right? Also make sure "Is Kinematic" is unchecked on the rigidbody

[short osprey]

3D game yep.

The Player has a rigidbody. Kinematic is false, collision detection = continuous dynamic if that matters

[quartz folio]

Show the inspectors for both objects

[quartz folio]

How does "Movement" work?

Is it applying forces to the rigidbody?

[swift falcon]

on Collision enter must have rigidbody otherwise it wont work

Collision wont detect anything if no rigid body

[simple egret]

You indeed need to make sure the object is moved in a way that respects the physics engine

Modifying transform.position isn't one

[short osprey]

Its translating the transform, which im aware isnt ideal, but im trying to stay true to the tutorial and it works for him

public class Movement : MonoBehaviour
{
    [Header("Values")]
    [SerializeField, Tooltip("The amount of units moved per second in a given direction.")]  float movementSpeed;
    private Rigidbody body;

    // Start is called before the first frame update
    void Start()
    {
        body = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        Vector3 direction = new Vector3(Input.GetAxis("Horizontal"), 0f, Input.GetAxis("Vertical"));
        transform.Translate(direction * movementSpeed * Time.deltaTime);
    }
}

[quartz folio]

It's so not ideal that it won't work

[short osprey]

i did AddForce first but that causes it to slowly build up over time, being very slow to gain speed and very slow to slow down once the key is released. Even setting the velocity to the vector directly had that effect

[quartz folio]

If that object was kinematic and the other object had a rigidbody it would work (though you should use MovePosition, not the Transform). Without that setup you have to use Rigidbody functions. And yes, it's not straight forward if you don't know what you're doing, as velocity, drag, momentum, all come into it.

[short osprey]

so if the object that should turn red were kinematic it'd work?

[quartz folio]

The objects have to match in the collision matrix https://unity.huh.how/physics-messages/collision-matrix-3d

[short osprey]

i see. cheers.

[short osprey]

I changed movement.cs' Update definition to

void Update()
    {
        Vector3 direction = new Vector3(Input.GetAxis("Horizontal"), 0f, Input.GetAxis("Vertical"));
        body.MovePosition(direction * movementSpeed * Time.deltaTime);
    }

and now it wont move at all

[quartz folio]

MovePosition doesn't take a movement vector

[short osprey]

from the desciption it moves the object towards a vector. Shouldn't said vector be direction * movementSpeed * Time.deltaTime as well? since its a bit every frame

[quartz folio]

https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

position Provides the new position for the Rigidbody object.
Description
Moves the kinematic Rigidbody towards position.

[short osprey]

oh yea adding the current position makes sense

I have a Unity Netcode for GameObjects multiplayer game and a GameManager in my scene. I want to create a function that will return a reference to a player's GameObject based on its connected client ID. My solution was to create a variable in the GameManager called latestRequestedPlayer which would get updated by the server when the GetPlayerByID() function was called, and this would then be returned to the object that called this function.

    public void GetRequestedPlayerServerRpc(ulong id)
    {
        var playerObject = NetworkManager.Singleton.ConnectedClients[id].PlayerObject;
        UpdateRequestedPlayerClientRpc(playerObject.gameObject);
    }
    [ClientRpc]
    public void UpdateRequestedPlayerClientRpc(GameObject playerObject)
    {
        latestRequestedPlayer = playerObject;
    }

    public GameObject GetPlayerByID(ulong id)
    {
        GetRequestedPlayerServerRpc(id);
        return latestRequestedPlayer;
    }```

The problem is that you can't pass a GameObject in an RPC call so I'm wondering if anyone knows a solution or workaround to this.

How does one correctly change the font of TMP in a script? I currently have the following code:

        TextMeshProUGUI text = textObject.AddComponent(typeof(TextMeshProUGUI)) as TextMeshProUGUI;
        text.font = Resources.Load("Assets/Fonts/Pixelated SDF") as TMP_FontAsset;
        text.text = "Level " + (index+1);

But nothing seems to be happening. When looking at the font in the inspector, it is still the default font

When applied from the inspector tho, it works

[simple egret]

Make sure Resources.Load does not return null, and that the type is correct. Casting with as returns null if the type cannot be converted

Recommend using a hard cast (TMP_FontAsset)Resources.Load(...) or the generic Resources.Load<T>(string)

[rocky helm]

Indeed it is null

Should have thought about trying that myself

[rocky helm]

Neither of these work unfortunately

[simple egret]

So the resource wasn't found

[rocky helm]

Does the asset have to be inside the resources folder?

[simple egret]

Make sure you have any Assets/Fonts/Pixelated SDF path under a valid Resources folder as per the docs

/**/Resources/Assets/Fonts/Pixelated SDF.*

(file with any extension under a "Resources" folder anywhere in the project)

[rocky helm]

Yeah, it works now, thanks! I just looked at an example where "Assets/blah/blah" was used and assumed it doesn't have to be inside the Resources folder

Hi. I need help. My input axis for horizontal is setting itself to -1 automatically, as my screenshot shows. I'm also sharing the full class script, but the only thing you need to notice is that direction should only change when I press keys, yet it sets itself to -1 and I am not pressing anything.

public class CombatLeaderInput : MonoBehaviour

    [SerializeField] Vector3 direction;
    float velocity;

    // Update is called once per frame
    void Update()
    {
        if (state.State != CombatState.Active &&
            state.State != CombatState.Submenu)
            return;
        HandleInput();
    }

    void HandleInput()
    {
        direction = new Vector3
        (
            Input.GetAxisRaw("Horizontal"),
            0,
            Input.GetAxisRaw("Vertical")
        );
        agent.velocity = direction * velocity;
    }

    void UpdateSpeed(int sogginessStacks)
    {
        velocity = ccd.Speed;
    }

    public void SetLeader(int index, CombatCharacterData data)
    {
        print("Calling set leader.");
        if(ccd != null)
            ccd.EffectsHandler.Sogginess.onStacksChanged.RemoveListener(UpdateSpeed);
        ccd = data;
        agent = data.GetComponent<NavMeshAgent>();
        velocity = data.Speed;
        data.EffectsHandler.Sogginess.onStacksChanged.AddListener(UpdateSpeed);
    }
}

And here is the Input Manager.

By the way, I tried toggling between GetAxis and GetAxisRaw and the same thing still happens.

However, I'm not sure what to do next. What's the best way of adding behaviors to specific items? For example, I want one type of item to act as a "gun", so it'd have variables for ammo, durability, and so on, as well as an equip function. Another type I could want in a "food" item, with saturation variables and so on. I'm not really sure how to achieve this without bloating my project with a bunch of different "types" of items. Anyone know a better way?

[stuck niche]

It was my USB controller. 😅 Thanks.

[verbal grail]

One way would be to layer your classes. Have ItemBehaviour inherit from MB. Then have GunBehaviour/FoodBehaviour inherit from ItemBehaviour. And any thing more specific that you plan on grouping from there just keep branching from those base classes.

[heady iris]

I like to use scriptable object assets to define individual items

you use code to describe how consumbles as a whole work

and then you just put data on the individual consumable definitions to tell them how they function

This is a good place to use [SerializeReference]

You can have an abstract ConsumableEffect class with an Apply method

then derive it to make things like ConsumableHealthChangeEffect, ConsumableKillsYouInstantlyEffect, whatever

[SerializeReference] List<ConsumableEffect> will give you a list of effects

note that you'll need a third party package to get an editor UI for that list

e.g. https://github.com/vertxxyz/Vertx.SerializeReferenceDropdown

also, huh, this supports UIToolkit!

I might switch to it...

[obsidian bridge]

I swapped z with x and it made it worse

[cold willow]

So I have this unity method that gets called on fixed update

void ApplyMovement()
    {
        Vector3 moveDirection = transform.forward * movementInput.y + transform.right * movementInput.x;
        Vector3 desiredVelocity = moveDirection * moveSpeed;
        
          // Calculate the Y velocity separately to allow free vertical movement
        Vector3 currentVelocity = movementManager.rb.velocity;
        Vector3 yVelocity = new Vector3(0, currentVelocity.y, 0);
        Vector3 xzVelocity = new Vector3(desiredVelocity.x, 0, desiredVelocity.z);
        
        // Apply acceleration to the X and Z velocities
        Vector3 accelerationVector = (xzVelocity - currentVelocity) * acceleration;
        
        movementManager.rb.AddForce(accelerationVector, ForceMode.Force);
        
             // Limit the maximum speed for X and Z axes only
        Vector3 clampedVelocity = movementManager.rb.velocity;
        clampedVelocity.x = Mathf.Clamp(clampedVelocity.x, -maxSpeed, maxSpeed);
        clampedVelocity.z = Mathf.Clamp(clampedVelocity.z, -maxSpeed, maxSpeed);
        clampedVelocity.y = yVelocity.y;
        movementManager.rb.velocity = clampedVelocity;
     }

The issue with this method is that whenever it gets called, it makes my player fall super slowly. Any idea why? If I remove this line

movementManager.rb.AddForce(accelerationVector, ForceMode.Force);

Then the player falls just fine, but if I keep it in there the player falls extremly slowly.

But I cant just remove that line because then my movement stops working obviously.

I have a fighting game I am creating where I am trying to give players the option to have tap jump on or off (being able to press up arrow to jump). I'm trying to use control schemes but it doesn't appear to work. I have one called Tap Jump and one called No Tap Jump, where Tap Jump has 2 additional keys for jumping. In practice, no matter which control scheme, the characters always have tap jump. How would I fix this?

[cold willow]

Not to familiar with the new input system, but I would also try asking here #🖱️┃input-system

I have a generic class with MyClass<T1> : IT3 where T1 : IT2. I want a property on interface IT3 that returns TI as an IT2. Is there a way to do this without being confusing?

I am not allowed to put a property in MyClass<T1> that returns T1, to satisfy an IT3 interface requirement for a method that returns IT2

I would need to make a totally different method in MyClass that returns an IT2

If your game object is inactive your script methods will not be called

[upbeat gull]

Wich game object? The one with the script I guess ?

( for information the game object with the script on isn't set inactive)

[idle crow]

Hey guys, I'm having trouble remembering the name of a function that works to rotate an object n degrees per second towards a direction! If anyone knows it, thanks in advance!

[leaden solstice]

Your code has gameObject.SetActive(false)

[spring creek]

Well, I think you're thinking of two methods, lerp or movetoward combined with rotate

Or maybe something from DOTween?

[idle crow]

Yeah found it, rotate towards seems to be filling the bill.

Thanks brother appreciate it though.

[spring creek]

Ah yeah, of course! Glad you found it

[dense swift]

hey so basically I'm making a clone of Breakout for school and I want it to be as accurate to the original as possible, so I'm trying to make it that the speed of the ball increases every 4th collision but I'm not sure how. my code --> https://gdl.space/wisihaleki.bash

it does count, it just doesn't affect the speed

[buoyant crane]

if(count == count + 4) will never be true

[broken nest]

In short, I think you’ll want use the modulo operator. Something like:
Float speedModifier = count % 4;

[buoyant crane]

ah clever

I was thinking modulo check in the if statement, but this is pretty simple

[broken nest]

Actually no. Sorry just do integer division

[dense swift]

wait so how would I write that?

[broken nest]

same but change the % to /

You may have to cast the int to float, but c# might just do it for you

[buoyant crane]

RamblinQ’s idea would be to store the total count and divide (integer division) that count by 4. You can also have the if statement check if count is a multiple of 4 after you increase it

[dense swift]

this is all a bit confusing for me since I'm not very experienced 😅

[buoyant crane]

It should work fine without the conversion, they only want to increase the speed after every 4th collision

[buoyant crane]

You can check if a number is a multiple of 4 by checking if it’s remainder is 0

int number = 8;
if(number % 4 == 0)
{
   // 8 has a remainder of 0 therefore it’s a multiple of 4
}```

[low summit]

hey yall do you guys know of a way to change the move speed variable in script? its using the unityengine.xr.interaction.toolkit

the variable isn't anywhere in the script and I can't find a way to alter it

[dense swift]

ok wait so I keep it counting, add a speedModifier that = count / 4, and then add that check inside the if statement?

[buoyant crane]

Think about it like this. You count the hit 3 times. On the 4th one you increase the speed. To figure out if it was the 4th hit you would use the % to figure out if the number was a multiple of 4

[dense swift]

woah! thank you so much that works, I changed it to this if (collision.gameObject.tag == "YellowBrick")
{
count++;
if(count % 4 == 0)
{
speed = speed + 1f;
}

sorry the formattinfg is awful I'm not used to formatting in discord

[buoyant crane]

You just need a reference to it and modify it just like any other variable https://docs.unity3d.com/Packages/com.unity.xr.interaction.toolkit@2.0/api/UnityEngine.XR.Interaction.Toolkit.ContinuousMoveProviderBase.html#UnityEngine_XR_Interaction_Toolkit_ContinuousMoveProviderBase_moveSpeed

[low summit]

im trying to reference it from another script

when i try to get the component for the actionbasedcontinousmoveprovider

it says that it doesn't exist

how do i reference it if i can't do that?

[buoyant crane]

It looks like your ide isn’t configured, the issue is probably from not having the correct using statement

omg

u are

such a life saver

ive been wondering

why this shit isn't highlighting errors for so long

[devout harness]

I'm having difficulty understanding the field distance in the ColliderDistance2D returned by Collider2D.Distance()

[spring creek]

It's a method, not a field
It is used to calculate the minimum distance between it and another collider
https://docs.unity3d.com/ScriptReference/Collider2D.Distance.html

Oh wait

I misunderstood sorry

Thought you meant the method call itself. But what I said basically describes the value.

[devout harness]

No worries-- I'm just unsure what distance its measuring exactly

[buoyant crane]

If it helps to visualize it https://github.com/nomnomab/RaycastVisualization

[devout harness]

Ahhh okay, so when they're overlapping, the distance will be negative representing the amount of penetration?

I.e. if one object was moved by distance * the normal it would be depenetrated?

[buoyant crane]

Yup https://docs.unity3d.com/ScriptReference/ColliderDistance2D-distance.html

negative indicating that they are overlapped.

[devout harness]

Also extremely awesome resource, thank you for sharing!

[torn eagle]

Sent this in #archived-networking but not sure if it's worth asking here as well as I'm not sure how to go about the code either!

Hey! I'm trying to make a game and the gist of what I want to do.

1: Player walks around environment.
2: Player closes game.
3: Final player position is sent to a network and saved.
4: Whenever somebody opens the game objects are instantiated at all those saved positions.

Is there any free way to implement this?

[rigid island]

don't crosspost but also , are you talking about a saving system? doesn't sound like a multiplayer thing

[low summit]

i can't get my player from falling thru my platform

it uses a layer based collision detection but i think im just not understanding how layers work

the platform is on the ground layer

and the player is on the player layer

i checked the collision box between ground and player

shouldnt that mean my player should collide with the platform?

[rigid island]

why are u doing this lol

u just need colliders

[low summit]

its a project for a club

this is the script they wanted to use

[rigid island]

you shouldnt have to mess with Layer based collisions unless you specifically want to ignore layers

[low summit]

we're gonna do that in the future

[rigid island]

what's that got to do with your current issue though

You need colliders for things to collide

[low summit]

i do have them

[rigid island]

show both

[low summit]

bro just keeps falling thru them

[rigid island]

show both object's inspectors

[rigid island]

ok entire inspector please no cropping

object names

[low summit]

this better?

[rigid island]

why does goround have rigidbody ?

[low summit]

why shouldnt it

[rigid island]

because its ground and doesn't need to move?

rigidbody = physics

ur ground is falling

[torn eagle]

Sorry!! And not quite? As player positions will be saved for everyone who runs the game not just the local player.

[low summit]

i was just trying to do anything to make it work tbh lol

i messed with the layers so many times

im missing something idk what tho

thats why im asking

[rigid island]

try it now without rigidbody on platform

[low summit]

no bro still falls straight thru

[rigid island]

does it fall thru without Player Controller

maybe its ur script and your grounded layer on it is set to none, thats sus too

[low summit]

when i remove the script it doesn't fall

[rigid island]

sounds more like storing position onto a database

[low summit]

omg.

i just noticed the ground layer option.

on the script.

bro how did i miss that

[rigid island]

lol probably not knowing what that field does

idk

is it working now?

[low summit]

yeah now it works but my character is bouncing up and down rly fast when its on the ground

[rigid island]

hard to know for sure , start by sharing the !code

nvm???

it stopped working??

[low summit]

okay i got it working again

but now it sinks half way into the platform and i can't move

[rigid island]

chances are your grounding is wrong

you still didn't share script so 🤷‍♂️

although by deault a rigidbody wouldn't sink unless the code is forcing it though

[lean sail]

For anyone whos used the kinematic character controller on the asset store, would you say it is better than just making a custom kinematic movement script?
Ive seen that it's not really for beginners but my movement shouldnt be extremely complicated. I'll at most have walking, sprinting, jumping, hovering, dashing

[rigid island]

by custom kinematic you mean making one using regular collider + code or character controller ?

[low summit]

https://gdl.space/raw/zukitiruma

[lean sail]

Just like a kinematic rigidbody and move position

[rigid island]

if its simplified make your own, maybe take some bits from it but if you look at the asset there is A LOT going on lol

[lean sail]

The kcc on the asset store seems to have a lot going on in it, which is good but also scary since I wont know the exact ins and outs

Yea lol

[rigid island]

I tried using it twice but found it tooo bulky to change anything on it

[low summit]

i got it

dw about the link i figured it out

[rigid island]

what was it?

also dont send raw version next time lol

[lean sail]

I guess I'll just try to make my own, since I really dont wanna get stuck down the line on how to make it do something like dash

[low summit]

theres a collision field that i didn't set for the sprite i was using

and whats the alternative to raw version loool sorry

[rigid island]

yeah exactly what I ended up doing, just adding anything to it was more work than just writing my own

[rigid island]

when you save you get the regular link lol

Hi. Could somebody kick me in the right direction to solve this issue:
There are AudioClips (ogg vorbis) packed into StreamingAssets and I need to load the clips in runtime and play instantly, but i'm constantly getting the chokes while the game's loading the clip from the bundle (oggs sized 2+ Mb create a quite visible delay that i'd like to get rid of)
what is the best practice to start playing audio by chunks, loading in the background without interrupting the game
(audio doesn't have to start exaclty the same millisecond I trigger it. it is okay if the sound will start a little bit later. most important part is that it shouldn't freeze the game)

[late lion]

How are you loading it now?

[glossy willow]

so far i've tried coroutines with assetbundle.LoadFromFileAsync
also tried setting up addressables with the same result

with AudioSource.Play() then

[late lion]

So it's not an .ogg file? You've packed it into an asset bundle?

[glossy willow]

there are hundreds or audio files, so i believe i have to pack them anyway

[late lion]

Alright, what import settings do you have for these files? That affects how they are loaded.

[glossy willow]

compression is chunk based, as well as i've tried uncompressed
i create a reference on startup with AssetBundle.LoadFromFile

[late lion]

Do you have Decompress on Load enabled?

[glossy willow]

hmm, no

[late lion]

That's better.

And it's only the longer clips that have noticeable lag?

[glossy willow]

i think so. the freezes i can notice on my pc are caused by files about 1.7Mb+ in size

[late lion]

How long are those audio files?

[glossy willow]

it may be up to 2-3 minutes

but i can't tell right now how long are they exactly

[late lion]

It's recommended to use streaming for clips that long. That's one of the import settings.

[glossy willow]

yeah, sounds reasonable. is there a reference to the corresponding article to read?

[late lion]

This is the documentation for the import settings
https://docs.unity3d.com/Manual/class-AudioClip.html

[glossy willow]

thanks. i'll go and read it now

i can also see Preload Audio Data <- this

Hi, not sure if this is the correct place to ask but: I have a base class called UIComponent that inherits from MonoBehaviour, and I have a class called UiContextMenu which inherits from UIComponent. What I'm trying to do is assigning a list of UI components via the inspector, and I want to assign scripts that inherit from UIComponent, but it's not letting me put inheritors into the inspector field. Is there a way to achieve this?

[mossy snow]

you're doing it correctly, so more context is needed. Are you sure whatever you're trying to put there is valid? Probably the most common issue in this case is trying to assign scene objects to an asset (prefab or SO)

[main token]

I'm trying to assign the script directly, apart from that everything should be correct

[mossy snow]

the script from where?

[main token]

directly from the folder

[mossy snow]

that makes no sense, as a component it MUST exist on a GO. If you're trying to drag the script file itself, it's failing because the expected type is MonoScript and would be wrong and nonsensical regardless

are you doing something with reflection? Maybe I misunderstood your original intent here because I thought that was a list of UIComponent, and maybe what you wanted is a specific type that you will later create an instance of

[main token]

Nah, I just wanted to make a list with the UI Components needed for a certain "page", that will then initialize all component behaviors

[mossy snow]

then you're not looking to serialize a UIComponent instance, you want to serialize Type. This design is pretty smelly though, why wouldn't you just provide a prefab with the components configured?

[main token]

I'm using UI Toolkit, so behaviors have to be programmed

well I guess u could still do that, idk that's just the way I wanted to design it

[craggy veldt]

pretty sure you can obj.AddComponent(monoScript.GetClass());

(also, not following the conversation)

the GetClass is the key here

Do not use dynamic.
