[quartz folio]

visual studio code bad (with Unity) 🤷

[heavy hornet]

Yeah, well it's the only option for me...

[quartz folio]

Are you a student?

[heavy hornet]

Yes

I could use Rider...

but I don't know it...

Is that the "preferred" IDE for Unity devs on Linux?

[quartz folio]

It's the preferred IDE on every platform if you can get it

VS Code is the least supported one

[heavy hornet]

Alr I'll try it

But it'll cost me when I'm not a Student anymore...

[quartz folio]

They're not supporting VS Code's debugger plugin, and they don't even add the VS Code package to new Unity projects any more

[heavy hornet]

Yeah, I saw that

149€/year for Rider o.O

[quartz folio]

I pay for Rider, it's very good. When the EAP is running you can also use that for free.

The cost goes down over the course of 3 years

[heavy hornet]

I mean yeah, JetBrains IDE's are good... but I don't have the money to pay 149€ for it as a hobby

[quartz folio]

If you don't want to go through the student stuff right now the EAP is currently running so you can just download that https://www.jetbrains.com/rider/nextversion/

[heavy hornet]

I have Student stuff already

I use IntelliJ Ultimate

[dim spindle]

is VS fine (not code)

[quartz folio]

Rider should feel very familiar then! Otherwise, you'd probably get more out of asking about VS Code on the forums

VS is completely supported

[heavy hornet]

89€ is better... but still quite expensive for a hobby

[heavy hornet]

idk I never used it

[heavy hornet]

:)

[dim spindle]

ehhhhhhhhh there are a lot of hobbies where you spend a LOT more but thats kinda unrelated lol

[heavy hornet]

Hmm... true

[quartz folio]

Also should note that former student license holders get 40% off so you wouldn't be paying that 149€ for the first year, but anyway I'm sure you can figure it out, maybe when you're no longer a student Unity will have updated to .NET 7-8 and VS Code will become supported again

[heavy hornet]

:o 40% off sounds nice

[heavy hornet]

I don't think I'd be switching back to VS Code when I already did a lot in Rider

¯_(ツ)_/¯

[arctic lintel]

is there a way to put my custom enum List as argument in PhotonView.RPC using pun2?

[quartz folio]

Might be better to ask in #archived-networking

[arctic lintel]

ok

[heavy hornet]

Ooohhhh.. thanks Rider ig... that is cool ngl

[lost dome]

How can I change an input joystick axis from being from -1 to 1, to 0 to 1?
Basically, -1 = 0, -0.5=0.25, etc…

[quartz folio]

(x + 1) * 0.5

[bitter saffron]

Is it possible to use Animationcurves in the Unity UI System or do we have to make or own splines?

[leaden ice]

Everything is possible.

Kinda depends what you mean by "use" here

use them to do what

[bitter saffron]

I mean like a slider or button, just drop in an animationcurve so players can for example tweak a curve to determine spawn behavior in the build.

[leaden ice]

public AnimationCurve myCurve; works out of the box.

[bitter saffron]

Yeah but thats inspector only, isnt it? What I mean is instead of this here:

I want something like this here I did for the level nodes:

I mean it is programmable but maybe unity has some ready to use Unity.Ui - Animationcurves where I just have to swap textures or something like that

[leaden ice]

This is a spline, not an animation curve

[leaden ice]

I don't know exactly what I'm looking at here TBH

or what it has to do with curves/animation curves

[bitter saffron]

nvm

[leaden ice]

Unity has a Spline package, if you're interested in splines.

[pallid sail]

isnt code i dont think but anyone know what the error
assertion failed on expression : 'Get SystemInterested(transform, system) != enable' means, 4 of em pop up after I end my play scene

[leaden ice]

seems kind of #archived-dots related? 🤔

[bitter saffron]

Could be that you have something in If Unity Editor like a variable

[dim spindle]

Does anyone have an idea about this? Other inputs work fine, and it works on windows, but just not on linux its very weird

I dont think its input settings? And im not sure what physics settings would make it not work on linux

Ok SO rays are getting cast at the correct position

between linux and editor in windows, the ray coordinates can be the same

but the item will only pick up on one system

hmmmmmmmmmmm, so i would assume its a physics problem between target systems

but why would it be different?

[plucky inlet]

Did you try to use a public layermask inspector value instead of your bitshifting 1 << 8 thing? Just to be sure there is no difference on both OS

[dim spindle]

I can try that yeah

layermask added, same result

including in logs

[dim spindle]

whoops meant to reply

[jaunty sleet]

I can not get my binary formatter save to work for the life of me

https://codeshare.io/mpbzLX https://codeshare.io/qPm8Ax Can someone look at my code and see if they can figure out whats wrong with it?

[leaden ice]

That's a good thing, you should not be using BinaryFormatter at all

[jaunty sleet]

why?

[leaden ice]

It's dangerous for your users

https://learn.microsoft.com/en-us/dotnet/standard/serialization/binaryformatter-security-guide

[jaunty sleet]

what should I use instead then?

[leaden ice]

the article mentions some alternatives. You can also use well known JSON serilializers like Unity's JsonUtility etc...

[jaunty sleet]

maybe it will work if I just switch the serializer to that then, because I couldn't find the issue with my code for the life of me other then the data just not coming through correctly

[leaden ice]

Well I mean in your test you're not even saving the data at any point

[jaunty sleet]

?

[leaden ice]

you never call saveLevel

so IDK what you think you're loading.

[jaunty sleet]

// test save and load methods with test note data
public static void test()
{
note[] notes = new note[3];
notes[0] = new note(1, true, 10, "note", "turnRight");
notes[1] = new note(2, true, 25, "note", "turnRight");
notes[2] = new note(3, false, 40, "note", "turnRight");

    foreach (note note in notes)
        Debug.Log(note.ToString());

    saveLevel("test", notes);
    note[] notes2 = loadLevel("test");

    foreach (note note in notes2)
        Debug.Log(note.ToString());
}

[leaden ice]

oh I missed it somehow lol

[jaunty sleet]

lol

[leaden ice]

you should be using using statements btw

whenever dealing with things like FileStream

[jaunty sleet]

what does that do?

[leaden ice]

there's a risk you are not closing your streams properly

it ensures streams are opened and closed properly.

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/using-statement

[prime sinew]

I see there's resizable window, but yeah, shame. Thought there'd be more

[jaunty sleet]

so in my case, I would use the using keyword like: using (stream) { LevelData data = formatter.Deserialize(stream) as LevelData; } ?

then I also don't have to close it after right?

[leaden ice]

Or just use File.WriteAllText / File.WriteAllBytes and skip all the stream stuff

[jaunty sleet]

I like the streams lol

Now I just have to figure out how to change my code to use JSON serializer

also, JSON stands for java script object notation, but I can use it in c#?

[prime sinew]

Yes

It's just a text format used to represent data. Not really a language or anything

[verbal pebble]

No idea if this is the right place for it. My player character is animated so his sprint is slower at the start, but full speed during the loop. The animations have no root motion. I'm assuming this is a code thing though, I need to figure out how to change the player character's speed so he's slightly slower at the start of the sprint with a pause before going full speed.

Had a look around online and couldn't quite find any info on what I'm trying to do, so there might be a term for it that I'm not aware of.

[potent sleet]

Animation Curve for movespeed

[verbal pebble]

Genius, that didn't come to mind at all. Thank you!

[jaunty sleet]

if I save a json file to a folder using write all text with the same name as a json file already there, will it overwrite the old file?

[prime sinew]

You could test it

[jaunty sleet]

that's probably what I'll do

[jaunty sleet]

https://codeshare.io/MNE0Je https://codeshare.io/EBEKJo I am having the weirdest issue with my constructor in these classes

nvm I am dumb

[inner yarrow]

What would be a good way to figure out all of the objects that are visible from a certain point in my scene? I considered raycasts, but figured that that would be bad for performance, and it would be very precise for scenarios where the center isn't visible, but the edges are.

[potent sleet]

bad performance?

[inner yarrow]

I don't know if that's accurate, I just figured that doing a raycast for every object in the scene is a bad idea.

[maiden breach]

https://docs.unity3d.com/ScriptReference/Renderer-isVisible.html as long as your point is a camera that is

[potent sleet]

nothing wrong with a bunch of raycast, the engine can handle a decent amount just fine

[cosmic rain]

It's not gonna be precise either. How do you know what to raycast against if not the center of the objects?

Unless you raycast per pixel on the screen, which is really gonna kill the performance.

I'd use what DROD mentioned or maybe iterate all the objects and do some math involving their bounding boxes, view point and frustum angle.
There might be a utility method to make it easier. That would still be pretty heavy depending on the number of objects...

[inner yarrow]

Yeah, that's kinda why I was hoping that there's a better method. The renderer.isVisible thing I don't think would work very well because it's not a camera, and if I'm reading correctly, that returns true if it's visible by any camera.

[cosmic rain]

What's the purpose of doing that though? Maybe there's a better solution?

[maiden breach]

Well you could put a camera there that only renders a certain layer. @inner yarrow

Duplicate the object your trying to detect as a child, put it on that layer and check its renderer etc

[inner yarrow]

I want this because I have to duplicate part of my scene, but I only need to duplicate the object's that are visible from a certain point.

[cosmic rain]

That would kinda involve some unneeded camera overhead(like rendering these objects)

[potent sleet]

https://xyproblem.info/

[maiden breach]

Barely, if theyre only rendering one layer.

[cosmic rain]

Maybe GeometryUtility.TestPlanesAABB the relevant objects?

[inner yarrow]

I'm not actually asking about my solution. My problem is needing to know which objects are visible from a point, and that's what I asked.

[inner yarrow]

Yeah, I guess I could try that.

[potent sleet]

not really specific enough to its purpose

is it a camera effect only ? or something

[swift falcon]

yo guys anyone know how to add a timer until the next line of code is activated?

[maiden breach]

Like for benchmarks? Stopwatch?

[swift falcon]

like a stopwatch

[potent sleet]

@inner yarrow this def

[inner yarrow]

ok, I'll give that a try.

[maiden breach]

No, Im suggesting Stopwatch class lol

[swift falcon]

im trying to have it so when a game object colides with another it waits for a moment then will change color

oh XP

[maiden breach]

Ah nope not Stopwatch

[swift falcon]

oh

[maiden breach]

You probably want to look into coroutines

[swift falcon]

ok ill read the doc and pull up a few vids, Thanks for pushing me in the right direction :>

[cosmic rain]

Or raise some flag and wait in update.

[pseudo scarab]

Hello I'm setting up a bunch of raycasts for hit detection in a melee game, I need to be able to set these points manually and I was wondering if its possible to create these positions through the inspector instead of adding empty gameobjects to each weapon to use as points. I tried using a list of vector3's but there's no visual for the placement of these points

[maiden breach]

You can add visuals using Gizmos and Handles

[true sapphire]

quick question: can you change the outer spot angle of a Light 2D in script?

[pseudo scarab]

o why didnt i think of that lmao

ty

[potent sleet]

ya probably

every component is a script

so probably

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.0/api/UnityEngine.Rendering.Universal.Light2D.html

[true sapphire]

oh lmao ty i didnt realize point light and spot light referred to the same thing

appreciate it

[potent sleet]

Yeah I think in 2D point lights also become spot lights with that thing

[swift falcon]

my OnCollisonEnter is bugging out it keeps saying its wrong but every other script reference looks like this plz help

https://codeshare.io/lonXbm

[leaden ice]

it keeps saying its wrong
Wdym? Are you getting an error? What is your full error message?

[swift falcon]

opps sorry here:

[leaden ice]

you have a yield return statement in OnCollisionEnter

You can only have yield return in iterator methods, which this is not one.

[swift falcon]

oh

[leaden ice]

an iterator method must have IEnumerator as the return type, not void

[swift falcon]

welp back to the drawing board i suoppose

[leaden ice]

why?

Just change the return type to IEnumerator

[swift falcon]

oh

[leaden ice]

OnCollisionEnter can be a coroutine

[swift falcon]

ok

[dim spindle]

Ok, I am really confused. I am trying to get a Raycast to work on both windows and linux. For some reason, my item pick up script works on windows, and in the windows editor but NOT on Linux.
This is the code for detecting a raycast. On linux, I get the print for "Pickup Press", and the print for "Ray Created" but not the "Ray Hit an Object". On windows, the "Ray Created" Coords MATCH the linux ones in my test case, but the linux one doesnt get the raycast to hit the item.... its really weird

public void Pickup_Pressed(InputAction.CallbackContext ctx)
{
    Debug.Log($"Pickup Press: {ctx.performed}");
    if (!ctx.performed)
        return;

    RaycastHit hit;
    Ray ray = main_camera.ScreenPointToRay(Input.mousePosition);

    Debug.Log($"Ray Created: {ray.GetPoint(0f)}");
    if (Physics.Raycast(ray, out hit, inventory_grab_range, mask)) // Do a Raycast with only layer 8 (Items)
    {
        Debug.Log($"Ray Hit An Object: {hit.transform.gameObject.name}");
        Transform hit_transform = hit.transform;
        GrabItem(hit_transform.gameObject);
    }
}

[leaden ice]

are these objects moving around quickly or recently before this code runs?

[dim spindle]

they are kinematic atm

for testing

the code runs whenever i press E

[leaden ice]

that doesn't really answer the question 😉 Kinematic objects can move via script

[dim spindle]

ok well they are not moving

[leaden ice]

Is anything messing with Time.timeScale or Time.fixedDeltaTime or Physics.autoSimulate ?

[dim spindle]

1. No, 2) uhhh No, 3) i dont think ive ever seen that

would it only be in my own codebase?

i can do a search through my IDE

[leaden ice]

It's possible for plugins/assets to change these things

but not likely. Worth looking though

I know for example Obi Rope messes with autoSimulate for example

[arctic ingot]

Well this is interesting...
My editor has crashed out of nowhere after putting the same object in both the Viewport and Content section of a Scroll Rect. It seems to crash every time I open the specific scene where I did this...

[leaden ice]

submit bug report to Unity if you can reproduce it

[arctic ingot]

Already done, mainly was hoping someone had an idea here 😅

[dim spindle]

in my codebase nothing is changing those

[arctic ingot]

Thing is...this happens all the way from 2020 to 2023 alpha 2

[dim spindle]

can you reproduce it though? if you do that again in another scene does it die again

[leaden ice]

Imean there's not much to go on from the stack trace. That's about as generic as a segfault gets.

[arctic ingot]

I can try to yeah

[leaden ice]

Unity will be able to reproduce it with debugging symbols and figure out where in their own native C++ source code it actually happens

without that it's shrug city

[arctic ingot]

One thing to note, if I force it to load a different scene, it doesn't crash

[dim spindle]

wdym by that

[arctic ingot]

Yeah I thought so

[arctic ingot]

literally going in the configs and changing the last loaded scene

[dim spindle]

@leaden ice anything else that would kill it? and something that would ONLY happen on linux?

specifically ubuntu

if that matters

[leaden ice]

I'm noting that you're doing Input.mousePosition even though you're using the new input system. Shouldn't you do Mouse.current.position.ReadValue() instead?

maybe the "both" input mode doesn't work on Ubuntu

[dim spindle]

that WOULD probably be a good idea

yeah

maybe

i just used the old one because i new the magic trick for it and it still worked

so why change it lol

[leaden ice]

this could be a why 😉

[dim spindle]

but it IS showing the coords of the raycast correctly

so i doubt thats the issue

would still be good to change for compatibility

[leaden ice]

oh is it? My thinking was maybe mousePosition was returning 0, 0, 0

[dim spindle]

yeah no its returning the correct value for the ray position

[leaden ice]

ray.GetPoint(0f) is just the origin of the ray

which will always be the same

no matter what mouse position you plugged in

it's just the camera's position

I think it could be the mouse thing still

[dim spindle]

yeah

but isnt it ray to screen point

meaning

[leaden ice]

yes

The ray starts at the camera position

[dim spindle]

ohh nvm i get it now im just bad at thinking

yeah

i have 0 braincells and i should quit gamedev 👍 👍 👍 👍

jk

[leaden ice]

try it and lmk

[dim spindle]

i dont wanna try quitting gamdev!!!!

BTW

how can i replace Input.GetAxisRaw("Mouse Y")

and the other one

with new input system so i never use both anymore

[leaden ice]

Mouse.current.delta.ReadValue().y

[dim spindle]

thank you

i can also just shorten it Vector2 mouse_delta = Mouse.current.delta.ReadValue();

very nice

only downside is it goes HYPERSPEED compared to the old one

very weird

i will just apply a fixed multiplier ig for now

[arctic ingot]

Not really sure if I have it the same way I did before but it hasn't crashed so

All I can go off of is that it happened after I put the same object in both the viewport and content section of the Scroll Rect, it happens no matter the unity version, and it crashes every time I open the scene

I looked at the scene inside a text editor and it looks fine so I doubt the scene itself is corrupted

[leaden ice]

hmm you're not multiplying by deltaTime right? I think I've heard of this before... people saying they get different scaling on the new mouse input 🤔

[dim spindle]

i dont see it but i AM skimming

so

void mouse_look()
{
    Vector2 mouse_delta = Mouse.current.delta.ReadValue();
    Vector2 raw_frame_velocity = Vector2.Scale(mouse_delta, Vector2.one * menu_handler.look_sensitivity * player_camera_control_adjustment);

    frame_velocity = Vector2.Lerp(frame_velocity, raw_frame_velocity, 1 / smoothing);
    flash_frame_velocity = Vector2.Lerp(flash_frame_velocity, raw_frame_velocity, 1 / flashlight_smoothing);
    look_velocity += frame_velocity;
    flash_look_velocity += flash_frame_velocity;
    look_velocity.y = Mathf.Clamp(look_velocity.y, -90, 90);
    flash_look_velocity.y = Mathf.Clamp(flash_look_velocity.y, -90, 90);

    player_transform.rotation = Quaternion.AngleAxis(look_velocity.x, Vector3.up);
    camera_transform.rotation = Quaternion.AngleAxis(look_velocity.x, Vector3.up) * Quaternion.AngleAxis(-look_velocity.y, Vector3.right);
    flashlight_controller.Move_Flashlight(Quaternion.AngleAxis(flash_look_velocity.x, Vector3.up) * Quaternion.AngleAxis(flash_look_velocity.y, Vector3.right));
}

https://gdl.space/ibitonacel.cpp

even this isnt doing it

smh

ok andddd

it does not work

[timid moon]

EditorWindow - What is called when I move/create a new window?

[dim spindle]

still

[leaden ice]

ehh you're doing all kinds of like... mouse look acceleration in this code

hard to judge what's up

[dim spindle]

fair enough

but tested on a lower framerate system (the linux system that wont raycast correctly djfsklfjasf) and it didnt scale weirdly after my multiplier

so i think we are good

anyways

raycast issue still stands

this is weird

im gonna try setting some sort of reference point maybe and picking a point a few units down the ray

[leaden ice]

really? Could've sworn that'd be it

[dim spindle]

maybe that would provide insight

yeah

no clue

its real weird

i just turned off both mode as part of the next update im gonna try

any other suggestions

it takes a few mins to update so i dont wanna update without some bigger change

[leaden ice]

nothing I can think of

maybe add more logging

like logging mouse positions, the ray definition itself, the layermask value, inventory_grab_range, main_camera etc..

just dump a whole bunch of info and see what's different if anything

[dim spindle]

inventory_grab_range is a const

its 5f

main_camera is set in Awake() using Camera.main

but again the ray coords are teh same

so its 99% sure the main camear

[leaden ice]

It's theoretically possible for this to return a different thing, especially if you have multiple Main Cameras in the scene by accident

[dim spindle]

none of my other cams have main cam but i can try

[leaden ice]

and in a less likely scenario - you mess with camera tags during initialization

[dim spindle]

i think ive used tags once

[leaden ice]

or maybe you instantiate the main camera?

[dim spindle]

no

[leaden ice]

Could be an order of execution issue if the main cam is instantiated

[dim spindle]

main cam is in the scene, and has a script that moves it to the client-owned player object when the scene starts

not other player objects

that would be broken

lol

[leaden ice]

hmmm ok so

networking is involved?

That's definitely a monkey wrench

[dim spindle]

yeah

i feel like it wouldnt affect it too much though?

idk

also there are weird cases where you CAN pick up items

but i havent found anything consistent yet

so realllllly not sure

[leaden ice]

Networking affects everything 😬

[arctic ingot]

:/

I've uh...I seem to have broky

[leaden ice]

Looks like you've got a broken scene file

[dim spindle]

but like its a raycast and you are the host and it works on two seperate machines and the editor, both as client and as host

and on linux it does not work as host OR as client

but idk maybe linux networking hates netcode

[arctic ingot]

yeeeup
Time to figure out what to do about this 🥲

[dim spindle]

do you use version control?

[arctic ingot]

Not for this project

[dim spindle]

is it not a big one

or what

[arctic ingot]

Company security standards

[leaden ice]

oh btw almost every networking framework absolutely messes with Physics.autoSimulate which I was mentioning before.

Which networking framework are you using?

[dim spindle]

netcode

[dim spindle]

that might do it

but

why on linux

and not windows or other windows or editor windows

[arctic ingot]

objectReference: {fileID: 2077924899, guid: 00000000000000000000000000000000, type: 0}

[dim spindle]

also what do you mean earlier by the actual definition of the ray?

[leaden ice]

basically just printing out the ray

[dim spindle]

{ray} ?

you can call multiple casts on the same ray right?

i wanna try a mock cast for debugging that doesnt have item restriction

like flag mask i meant

[leaden ice]

yeah i mean just printing the actual ray itself

[dim spindle]

it is just printing rays lol

it looks like its working fine

but its not

[leaden ice]

Kind of a weird "hail mary" shot here. What happens if you run Physics.SyncTransforms(); right before the raycast

[dim spindle]

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

it just works tho

but like

only sometimes

the raycast hit an item, and when i went to try those coords from the log

it worked on the windows version

so the coords and dir are correct

im confused lol

ok so it only hits my items on very specific areas in linux

will you be here tommorow i wanna go sleep rn

and also when the ray DOES hit, it just picks up the item as expected

so its something with the ray not hitting for some reason

alright then

pain\

[dim spindle]

i dont wanna wait another 6 mins before sleep so gn

[red flax]

Hi I was wondering if someone could help me,

So basically I'm trying to setup a custom editor window, to automatically select an object from my project folder to show up in the inspector, basically what normally happens if you select it normally with the mouse but I just wanted to tie it to button click, is there anyway to do that?

Quite hard to google this since you type in something along the lines of selection and inspector, and you get specifically editor related setup, Selection.gameObjects (which only works for objects in the scene not project folders).

Any help would be appreciated, thanks!

So this works, it didn't work for me the first time around (and also the documentation saying the object selection in the scene is misleading) because I didn't setup the path correctly but basically in order to select something from a specific folder, you'd do
UnityEngine.Object objectYouWantToSelect= AssetDatabase.LoadAssetAtPath("Assets/Project/Folder/ObjectInFolder.asset", typeof(UnityEngine.Object));
Selection.activeObject = objectYouWantToSelect;
and that does the trick!

okay sorry a bit more work than what I thought, but basically this is what I found https://forum.unity.com/threads/selecting-a-folder-in-the-project-via-button-in-editor-window.355357/ , I have to use the selection bit and then the ping object method call, couple of steps in between but overall it's pretty simple to setup

[prime sinew]

nice, thanks for sharing!

yup no problem! I setup a way to load scenes from a window, since you know it's annoying to have to shuffle through and find your scene, so what something else but for specific scriptable objects, the cool thing is having a button that auto generates the code for the buttons (good ol' automation) so once I figure out the kinks to selecting an object, it's gonna be updatable with the click of a button 😄 it's pretty cool having code generate code

Hello, just wondering if there is a neater way to do something like this? It stores all the different positions my blocks can go in for each level. I was thinking SO? Although it will probably be a pain to enter each of the positions into it.

[potent sleet]

A list

[simple edge]

I agree with that, but it depends on your use case a bit, and how you structured your levels

You could've made a scriptable object containing a list of vector3s, so that each level would have its own scriptable object
But it kinda makes me wonder why you wouldn't just use different scenes at that point

[latent latch]

Those y values looking pretty precise

[plucky inlet]

The position on y and z seem pretty equal, arent they? Is there any pattern that you could follow to turn this into code or at least calculate for each level on base of some empty transform clamping the max and min values? Just wondering what will happen when you go beyond level 3

[median folio]

Thanks all for the feedback I did feel this was messy when putting it together.

I think some form a list and calculation to determine the values would work well, I hadn't realised how similar they work so I think I might be to create a loop to generate them instead.

'level' was probably a bad word to use - it's more of a wave, Once all three waves have been completed the next level (scene) loads.

[thin aurora]

SO is only useful here if there is more logic to it

Even then, this is hardcoded, and a SO is more for configurable data

A list is the right answer here

[plucky inlet]

Just to add, you could still combine SOs for the "level" with lists for the "waves", if he really needs to set it up manually

[simple echo]

hey guys! i have an 'invincibility' method for the player. so if the player collides with the enemy then they have 4 seconds of invincibility within which the enemy cannot attack the player. however, that does not seem to be working. i have attached my code for the invincibility method.

[humble thistle]

It'd be best to have a bool for the player saying they're protected and checking on damage if they are

[median folio]

@thin aurora @plucky inlet Cool that makes sense, I'll keep that in mind going forward I think a list might work once I get the loop figuring out to generate the values. I do like the idea of using using an SO to hold the lists for each levels if they do need to be hardcoded.

[graceful warren]

Hihi, so I have multiple player characters that all have different attributes such as stats. I have all the stats that a character would have as a scriptable objects. I'm currently trying to figure out how I would differentiate script-wise between the characters. Would it be with inheritance or is there another way? If I have characters inheriting from a base character script, how is that any different from not using scriptable objects?

[plucky inlet]

First question, do you use one scriptableobject per character?

[graceful warren]

Yes

[plucky inlet]

then you already have a separation for each character, dont you? Where are you stack exactly?

[graceful warren]

If I had three characters, and in the scripts it takes the stats and does whatever, do I just need the script copy pasted three times?

[rigid island]

You need 3 scriptable objects

[graceful warren]

I do

[rigid island]

You only need 1 script

[plucky inlet]

Exactly, you just use one script on all players but they take in different SOs as a parameter. Like GameObject A,B,C all hold the "Player"Script but with different ScriptableObjects attached to them.

[graceful warren]

Hmm that was how I had it. I just wasnt sure if that was going to cause issues

[rigid island]

maybe post the issue you had instead

[plucky inlet]

As long as you do not share any other static values between those scripts. But again, it depends on your setup. If you add fancy systems to it, it will surely cause issues you can solve. thats dev life 😉

[graceful warren]

I didn't really have an issue

I just didn't know if there was another way to do it

[simple echo]

okay thank you !

[graceful warren]

ty 👍

[rigid island]

there is many ways to do many things, but SO is a good modular way to do it

[plucky inlet]

Usually there are always multiple ways for one solution, but it always depends on the situation. Just test around, come here if you want help or suggestions, prototype system ideas and so on 🙂

[plucky inlet]

But I wont be tired to tell, if you use scriptbale objects, they will NOT persist their updated values in runtime. So if you think, your ScriptableObject is an easy way to save player stats over multiple runtimes, it wont. you have to store the scriptable objects state when you leave the game and overwrite it when starting the game. Just one thing to be sure about in SO handling

[graceful warren]

Good tell, I don't think the way I want to use the SOs involves changing their values but instead getting something from their values and changing that

like uhh

A stat such as constitution, it converts into health and instead of messing with the stat itself I just mess with the health

[plucky inlet]

Just wanted to warn you, cause I learned it the hard way back then 😄

[graceful warren]

I will keep that in my mind

[rigid island]

hehe use props!

I try not to make anything in SO public without it

[SerializeField] private int moveSpeed; public int MoveSpeed => moveSpeed;

[plucky inlet]

Not sure what you mean. It still will not save the values if you restart runtime, or dont I understand what you mean 😄

[rigid island]

Oh I meant so you don't accidentally change the SO values no? if they are public you might

[rigid island]

I misunderstood what you said here, thought you meant you accidentally changed your SO values lol

[plucky inlet]

Ah no, I was talking about, lets say, you load your player SO and you change its experience value from 0 to 20. If you restart the game in runtime, it will revert to 0, even if in Unity the values will stay at 20. 😄 But good point on your props tho about not accidentally changing them 🙂

[rigid island]

ah ok ! yeah def seen some strange YT vids talking about using SO as saves, big no no

so yeah good tip you gave there for that one!

[plucky inlet]

I mean I use it to save stuff in combination with a simple File being saved and loaded, but as you said, not solely on base of the SO system 😄

[graceful warren]

So if I wanted to change the stats on the SO I'd want to use something else?

Like if they level up or something of that sort?

[plucky inlet]

yeah, you basically just use the SO as a default structure. the data going in and out should be something updated in runtime and saved locally somewhere, so it can be your overwrite for your default SO state

[latent latch]

You can have different SOs per level if you wish, but ultimately they should only serve as a base template of the stats

[deft pebble]

Hey, I'm working on adding 3d object preview in UI through RenderTexture, so I have to position camera and object in the world. Are there any good practices of doing that? And if I'll need to render multiple objects with multiple cameras at the same time, how should I position them?

[graceful warren]

So what would be the alternative?

[plucky inlet]

A default class that you override with a database for example. The ScriptableObject system is useful for making pre defined things like classes, enemies, levels, items and so on. If you want to update those, you always have to detach the updated data from it. But that goes for a default class too. Detach it to a database, a file, a json whatever

[latent latch]

Honestly, it's probably fine to just put all the stat levels in the SOs. Maybe have a list of SOs, and you'd read each one accordingly everytime you level.

Or, a single SO per hero with a list of stats they have at each of their levels.

[plucky inlet]

But that way you would limit yourself to predefined values. If thats what he wants, sure can work then

[graceful warren]

No I don't want anything predefined

[latent latch]

Yeah, if you're starting out, which they are, I think that's preferable.

[graceful warren]

That's fair but the alternative doesn't sound that much harder and I would rather not dumb anything down if I don't have to

[latent latch]

Once you get the hang of serializing your data from and to then it's less of a problem.

[humble thistle]

I feel like I'm being stupid.
With the new input system (Using Unity events e.g callbacks).
How in the world do I figure out if the player is holding a key..

[plucky inlet]

Did you check the docs about the callbacks you can hook into? Like performed, IsPressed() and so on?

[humble thistle]

I have but I'm also tired so that's what I said I feel like I'm being stupid

I'm looking at the interaction part of the docs rn but I can't find the function for Hold interaction

[plucky inlet]

If you are tired, you might just wanna take a break?

[humble thistle]

[stoic plume]

Hi!

Does anyone know how to play a sound when you interact with an NPC? I've set up an Box Collider next to them and a Sound, but I am struggling to find a script/code when key "E" is pressed that they play a sound saying ex "Hello!". Anyone know how to code it?

[plucky inlet]

#🖱️┃input-system for how to get the E key and https://docs.unity3d.com/ScriptReference/AudioSource.html on how to play audio

[stoic plume]

Ty mate, but i can't see any inputs in the code when u press anything to trigger the sound. I want the sound to play inside the box. Is there another script for that?

[plucky inlet]

there is no PlaySoundWhenPressingAKey(Key, Sound); function. you gotta hook it together yourself. thats why I suggested you to talk in input-system to learn about how to actually call a fucntion with the button press AND look at the audiosource component to know how to call an audioclip. combined with a script of OnCollisionStay should get you going

[swift falcon]

Hello, I want to save my data on to a database, i haven't picked the data base because I dont know which database will be the one I need, I need my database to be able to do this:

• assume that you have 50 players and you want to save each of their names, scores and Profile pictures...
  I want a database that saves even the profile pictures.... can anyone help me by telling me which database i need to use?

[plucky inlet]

do you want to save them online on a server or just locally?

[swift falcon]

I want to save them locally or on a free platform you know like firebase

the important part if I keep them locally is to also keep the pictures

[plucky inlet]

How would you get the pictures?

[swift falcon]

browse for them

and of course if there's a saved database, load them in the beginning

[plucky inlet]

you can just use a simple file with json in it and the path to a downloaded image to do that, if you dont really work more with a database then just saving a list of players with images

[swift falcon]

here is the crux of the problem, do those data bases save the sprites... because those pictures aren't stored on the web... I want that if I move that database to another computer and run the app... the pictures will be loaded... I have thought about writing Json files... but no... I need to save the sprites themselves

[plucky inlet]

if you need to save an image, use base64 if you really need to

[swift falcon]

thank you.. and yes I do need to... I wont be synching those pictures in an online game

[swift falcon]

any other databases that can save pictures?

[plucky inlet]

a database is just a structure of text, those images in a database are also just text in the form of an URL to the file.

so you would have to use string values to create those images, which would be base64 strings

[swift falcon]

so I need to save the pictures in the resources folder for example? @plucky inlet and the database will load them right?

you know what... i will do it the old fashioned way

[plucky inlet]

you would save them to the persistentDataPath of your app on runtime and load them from there

[swift falcon]

yeah that's what I am thinking

[stone widget]

How would I go about making a save system for my game? It auto saves every X minutes and can be manually saved. and when you open the game and hit play, it loads the last saved level at the last saved position.

[swift falcon]

I think there's a video for brackeyes on save systems... you just have to trigger it in update every 5 secs

[plucky inlet]

What exactly are you struggling with?

[stone widget]

I have no idea how to save or load progress.

[plucky inlet]

Saving progress is basically saving values that represent the progress. thats something you should think about tho. So, for example. position of the player, experience of the player, inventory of the player. maybe enemy states and so on. Only you and your game know

[stone widget]

Ok thanks!

[hallow meteor]

hey

i have a problem here

[plucky inlet]

how about just telling the problem

[hallow meteor]

sorry i was recording the problem

so i have this script:

if(Input.GetMouseButton(0))
        {
            if(PlayerStats.movingObject != null)
            {
                print("testing1");
                Ray ray = cam.ScreenPointToRay(Input.mousePosition);
                RaycastHit hit;
                Physics.Raycast(ray, out hit, Mathf.Infinity, LayerMask.NameToLayer("Terrain"));
                
                    print("testing");
                    PlayerStats.movingObject.transform.position = new Vector3(hit.point.x, 0.1f, hit.point.z);
                
            }
        }

when i move, its kinda buggy

why?

im so confused

[plucky inlet]

"buggy" = ?

how do you set the moving object?

[hallow meteor]

If(Input.GetMouseButtonDown(0))

[plucky inlet]

that is getting the mouse button... not setting the moving object

how do you set ```cs
PlayerStats.movingObject != null

[hallow meteor]

oh

Wait lemme show u

The whole code

Vector3 mousePosition = Input.mousePosition;
        mousePosition.z = 10f;
        mousePosition = cam.ScreenToWorldPoint(mousePosition);
        Debug.DrawRay(transform.position, mousePosition - transform.position, Color.cyan);
        if(Input.GetMouseButtonDown(0))
        {
            Ray ray = cam.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;

            if(Physics.Raycast(ray, out hit, 100))
            {
                if (PlayerStats.movingObject != null)
                {
                    PlayerStats.movingObject.transform.Find("Movement").gameObject.SetActive(false);
                    PlayerStats.movingObject = null;
                }
                if (hit.transform.GetComponent<BuildingInfo>())
                {
                    hit.transform.Find("Movement").gameObject.SetActive(true);
                    PlayerStats.movingObject = hit.transform.gameObject;
                }
                /*Debug.Log(hit.transform.name);*/
            }
        }
        if(Input.GetMouseButton(0))
        {
            if(PlayerStats.movingObject != null)
            {
                print("testing1");
                Ray ray = cam.ScreenPointToRay(Input.mousePosition);
                RaycastHit hit;
                Physics.Raycast(ray, out hit, Mathf.Infinity, LayerMask.NameToLayer("Terrain"));
                
                    print("testing");
                    PlayerStats.movingObject.transform.position = new Vector3(hit.point.x, 0.1f, hit.point.z);
                
            }
        }
        if(Input.GetMouseButtonUp(0))
        {
            if (PlayerStats.movingObject != null)
            {
                PlayerStats.movingObject.transform.Find("Movement").gameObject.SetActive(false);
                PlayerStats.movingObject = null;
            }
}

[hallow meteor]

Here is it

The code

[plucky inlet]

So if you move your mouse to fast, you will lose the hit on your target and it wills et it to null and not move it. As I expected, you should hook the setting null of your movingobject to a mouse button up handler or something to release the instance you are trying to move instead of raycasting while you move it

[hallow meteor]

But its inside the onMosueButtonDown

Hey, I want to rotate a transform around the y axis slowly and with a limit. My current setup for that is something I threw together to "just work" but I need to phase it out now

if (Mathf.Abs(axisFront.transform.localEulerAngles.y) + 3f < 60 || Mathf.Abs(axisFront.transform.localEulerAngles.y) > 360 - 60 -3f) { 
            axisFront.transform.rotation = Quaternion.AngleAxis(3f * -agentController.moveAxis.x, axisFront.up) * axisFront.transform.rotation;
            axisBack.transform.rotation = Quaternion.AngleAxis(3f * agentController.moveAxis.x, axisBack.up) * axisBack.transform.rotation;
        }

What is the proper way to do this ? Its been ages ive used unity

[hallow meteor]

Does that mean if i dont stop holding mouse

The object will forever in Playerstats

[hallow meteor]

Oh yea, the raycast function in getmousebutton use to be a if condition. And the print is inside the if statement body, and the testing1 was printed but the testing was not

Im trying to simulate a rotating axle like this. To do this ive set up an empty game object as the axle root and connected two children to it at the end points. When I rotate the parent of them this gives the desired behaviour. Im however, not sure how to do this in code ? I want a hard limit to the rotation, e.g it cant turn more than 30 degrees in either direction.

Quaternion targetFront = Quaternion.AngleAxis(-steeringParameters.axisMaximumDisplacement, axisFront.up);
        Quaternion targetBack = Quaternion.AngleAxis(steeringParameters.axisMaximumDisplacement, axisBack.up);
        Quaternion nextFront = Quaternion.Lerp(axisFront.transform.localRotation, targetFront, Time.fixedDeltaTime * agentController.moveAxis.x);
        Quaternion nextBack = Quaternion.Lerp(axisBack.transform.localRotation, targetBack, Time.fixedDeltaTime * agentController.moveAxis.x);

        axisFront.transform.localRotation = nextFront;
        axisFront.transform.localRotation = nextBack;

Im not quite sure how to do this -- ive tried using Quaternion.AngleAxis but this is wrong and I cant quite figure out why :)

[leaden ice]

Just represent the current rotation as a float. Add or subtract from this float to rotate. Clamp the float to your desired angle range.

Then just drive the object's rotation from it

[dusk geode]

Right, since its a local rotation around a single axis i wont have trouble with gimbal lock

thanks!

[hard sparrow]

Is this right?

    {
        get { return currentShield; }
        protected set { currentShield = currentShield + value < 0 ? 0 : value; }
    }```

[leaden ice]

No this will cause a StackOverflowException immediately

You need to use a separate backing field

private int _currentShield; for example.

Your current code recursively calls the property.

anyone know how to program a mechanical belt system that transfers complete torque but doesnt break for reasons stated in image

[plucky inlet]

While thinking about it. Scriptwise you should have values for each wheel, the torque from the chain and additional torque from those gravity parts. And then the calculation of the summarized torques should give you the possibility to stop or accelerate the gears correctly. The belts would just be a visual representation and not really affecting the gears

Like each gear has a list of connected gears and their torque forces on "this" gear

I would say this is precisely the type of physical simulation problem that PhysX is bad at simulating and you'd probably be better off with a custom implementation or an asset like this:

Oh wow, that looks quite handy, thx for sharing 🙂

Hi everyone. I'm trying to lit sprites differently, while keeping them in the same Sorting Layer (so that transparency sort mode works as I intend). I'm using URP, but apparently I don't have Light Layers available.
If there's no workaround, is there a way use Custom Axis transparency sort mode to have sprites behave like they're in the same Sorting Layer?

[leaden ice]

To enable light layers: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.0/manual/lighting/light-layers.html#enable

[modest radish]

I'm on URP v14.0.5
Light layers seem to be implemented differently, I'm checking changelog and the functionality is now under "Use Rendering Layers". Thank you!

[granite nimbus]

where is documentation for Unity.Mathematics?
neither this https://docs.unity3d.com/Packages/com.unity.mathematics@1.2/manual/index.html
nor this https://docs.unity3d.com/Manual/index.html
looks like a documentation..

[leaden ice]

https://docs.unity3d.com/Packages/com.unity.mathematics@1.2/manual/index.html

If you want the scripting API it's here:
https://docs.unity3d.com/Packages/com.unity.mathematics@1.2/api/index.html

[granite nimbus]

but why it's formatted in different way than whole Unity docs?

[leaden ice]

It's a package

All packages have separate sites like this

[granite nimbus]

doesn't make sense to me, but whatever, thanks for the link

If you refer to a private variable in a method, and then pass that method as an Action to some other class, will that class be able to invoke the method?

Or how does that work

[ionic cave]

do you mean having something like public void Something(float floatNum){ floatNum += 1.0f) then calling private float aCoolFloat; Something(aCoolFloat)?

or do you have some example code i can look at

[hard sparrow]

In this case I'm modifying a private variable by another private variable. But I want to pass the method to another class (DelayedTrigger) which handles delayed triggers (since I want this method to be used after a certain number of rounds). And I want DelayedTrigger to be able to handle any kind of trigger, ideally

[cosmic rain]

local variables can't have accessors

[ionic cave]

I would need to see the code to get what you mean

[cosmic rain]

If you pass and execute the method as a delegate, it would execute exactly the same way as if you called it normally.

[hard sparrow]

Oh, so invoking the method is the same as using it in it's original place? So it can modify private variables and etc

[cosmic rain]

But, yeah, without an example, it's hard to understand what you're talking about.

[ionic cave]

just post a hastebin or something

[cosmic rain]

it is executed in it's original place. It's just called from somewhere else.

[hard sparrow]

this is all I needed to know, I think

[kind wolf]

how do i display big numbers without decimal points or scientific notations?

ive tried toString but it doesnt change anything

[swift falcon]

Hello

[pearl radish]

Oh no no, you ain't general fella

#💻┃code-beginner like you've been told

[swift falcon]

ah

wat

[ionic cave]

@kind wolf I think its .ToString("F2") or something like that for 2 decimal points

[kind wolf]

i dont want any decimal points tho

[ionic cave]

then ("F0")

[leaden ice]

myFloat:D``` to show without any decimal places

[hexed pecan]

:D

[kind wolf]

like this?

[leaden ice]

yes

[kind wolf]

it gives me an error

[leaden ice]

sorry apparently the x:D syntax is only available in string interpolation

[leaden ice]

which error

[desert shard]

massText.text = $"{mass:D}"

[leaden ice]

Oh yeah it's F0 indeed

[desert shard]

or just use F0 as you had previously

[leaden ice]

Apparently D is only supported by integral types. TIL

[kind wolf]

doesnt work either

same error

[leaden ice]

https://dotnetfiddle.net/Te3HVK

[leaden ice]

F0...

[ionic cave]

just do ToString("F0")

holy moly

[kind wolf]

yea this worked

[desert shard]

massText.text = $"{mass:F0}"
massText.text = mass.ToString("F0");

Pick one

[kind wolf]

oh those are the same thing

[dim spindle]

@leaden ice btw Physics.SyncTransforms or whatever did not work

sooooooooooooooooooooo\

ig its doomed

what is that question mark for @leaden ice sorry for ping again i just assume you left lol

[leaden ice]

the question mark is for idk what you're talking about. if it's an earlier discussion we had, refresh my memory

[dim spindle]

raycasts not working on linux

[dim spindle]

.

[leaden ice]

Yes I remember now the shrug is "idk"

[dim spindle]

well i guess im doomed

[uneven dagger]

Anyone know why this only shows up when i try to build my game? its having a problem with using UnityEditor.Animations;

[leaden ice]

YOu're trying to use editor only code in a build

notice the UnityEditor namespace

that's 🚫

[uneven dagger]

Ah, im new so forgive me if its a dumb idea on how I did it. I have an array of animatorcontrollers each having a different animation. When the game starts it takes the selected one and basically equips it. If I remove that then it just underlines everything in visual studio. Any alternative ways I can research or lookup instead of doing what I did?

[leaden ice]

what's the gameplay goal of what you're trying to do?

[uneven dagger]

Player buys a skin for cat and then equips it when the game starts the cat has a different animation based on what was bought and equipped

[leaden ice]

You should be using this
https://docs.unity3d.com/Manual/AnimatorOverrideController.html

[uneven dagger]

Alrighty ill readup on it i appreciate the advice

[sturdy fulcrum]

oes anybody know how to upload a Vroid model to unity

[leaden ice]

#🔀┃art-asset-workflow

[swift falcon]

i have a MutationStat class and a MutationSO scriptable object class that just stores a MutationStat and another value
i have a constructor that takes in the scriptable object: ```public MutationStat(MutationSO mutationSO)
{
stat = mutationSO.mutationStat.stat;
negative = mutationSO.mutationStat.negative;
canBeNegative = mutationSO.mutationStat.canBeNegative;
unscalingWithRarity = mutationSO.mutationStat.unscalingWithRarity;
mutationTarget = mutationSO.mutationStat.mutationTarget;
modType = mutationSO.mutationStat.modType;
}

then i get a list of the scriptable objects and make a new MutationStat```List<MutationSO> SOList = new List<MutationSO>(MutationSODBService.GetAllMutationStatSO());

for (int i = 0; i < SOList.Count; i++)
{
    MutationStat mutationStat = new(SOList[i]);
...
}

for some reason this ends up with the base scriptable objects being modified, anyone have any idea why that might be happening?

before & after

[leaden ice]

Nothing in the code you shared modifies anything

But all you're doing in the code you shared is passing references to your SOs around

if you think you're making copies of the SOs, you're not.

[swift falcon]

thought i was making a new one with MutationStat mutationStat = new(SOList[i]); ?

[leaden ice]

That's making a new MutationStat

not a new MutationSO

For this stuff:

stat = mutationSO.mutationStat.stat;```
You'd have to explain what those fields are

they are probably reference types

[swift falcon]

public class MutationStat
{
    public Stat stat;
    public bool negative;
    public bool canBeNegative = true;
    public bool unscalingWithRarity;
    public int mutationTarget;
    public StatModType modType;

    public MutationStat(MutationSO mutationSO)
    {
        stat = mutationSO.mutationStat.stat;
        negative = mutationSO.mutationStat.negative;
        canBeNegative = mutationSO.mutationStat.canBeNegative;
        unscalingWithRarity = mutationSO.mutationStat.unscalingWithRarity;
        mutationTarget = mutationSO.mutationStat.mutationTarget;
        modType = mutationSO.mutationStat.modType;
    }
}

[leaden ice]

where's the code that modifies the values?

[swift falcon]

        {
            MutationStat mutationStat = new(SOList[i]);
            int weight = CalculateWeight(SOList[i]);

            if (!mutationStat.negative)
            {
                positiveMutationStatList.Add(mutationStat, weight);
                if (mutationStat.canBeNegative)
                {
                    mutationStat.stat.SetBaseValue(-mutationStat.stat.Value / 2);
                    mutationStat.negative = true;
                    negativeMutationStatList.Add(mutationStat, weight);
                }
            }
            else
            {
                negativeMutationStatList.Add(mutationStat, weight);
            }
        }```

[leaden ice]

What is Stat?

Can you share the code for Stat

it's probably a class

meaning your MutationStat and MutiationSO both share a reference to the same Stat object when you do this:
stat = mutationSO.mutationStat.stat;

[swift falcon]

it's a class which holds a double value and a list of modifiers

[leaden ice]

so modifying one is visible in both

[swift falcon]

ohhh

you're right

[leaden ice]

key word being class

you'd need to make a new copy of it in the constructor for MutationStat to make them independent

[swift falcon]

yep that did the trick, forgot that lol, ty a bunch

[stuck lotus]

hello i am trying to create my own asset pack to host on github and i am getting close, only issue is that i cant seem to find a reference to reference to "UnityEngine.CoreModule" so its giving me issues with some transform stuff.

https://paste.ofcode.org/epAqsdMJYBwfPAuDMja3Dy

[leaden ice]

You just need to make sure this is NOT checked

you shouldn't need an explicit CoreModule reference

[stuck lotus]

let me try but i am pretty sure issue still persists, i didnt have that ticked from the start

[leaden ice]

what errors are you getting

[daring nymph]

any DOTween users? It's a bit annoying that DOKill is not chainable, because this would have been much shorter if it was. or is there a better way to do hover animation?

Packages\DungeonForge\Runtime\PcgScripts\EditorSideScripts\PCGManager.cs(302,51): error CS1061: 'Transform' does not contain a definition for 'AddComponent' and no accessible extension method 'AddComponent' accepting a first argument of type 'Transform' could be found (are you missing a using directive or an assembly reference?)

[leaden ice]

This is not an Asssembly issue

this is just a run of the mill "you wrote code that doesn't compile" issue

Only GameObject has AddComponent

Component / Transform do not

[stuck lotus]

i am sure this does compile as i had it on my normal scene

[leaden ice]

doubt

Does not and has not ever compiled in Unity

but this does

[thick socket]

public enum IconTypes
{
    Gems,
    Hearts,
    Coins,
    WoodChestKey,
    GoldChestKey,
    DiamondChestKey,
    HeroChestKey,
    DuplicateHeroShards,
    RandomHeroShards,
    Xp
}

I want to create a dictionary with each type with an int of 0...whats the best way to do this?

can't figure out how to do it with a foreach loop

[leaden ice]

I would say there's no need to prepopulte the dictionary with 0s

[stuck lotus]

var comp = this.transform.AddComponent<VoronoiMA>();

this does compile fine

[leaden ice]

is a line of code that doesn't compile.

[stuck lotus]

everything compiles fine lol

[leaden ice]

if that compiles you've added an extension method or something

[thick socket]

figure I would want to initialize it to 0 as other code might try and check the amount...and if the dictionary doesn't have the key it will throw errors

[leaden ice]

just use TryGetValue

public int GetGems(IconTypes it) {
  dict.TryGetValue(it, out int result);
  return result;
}```

0 is the default value for int so this will just work.

[thick socket]

fair enough

reguardless, I like the loot/feel of pre-populating the values....so Im going to

is there an easy way to do it for each enum 😄

[leaden ice]

https://www.c-sharpcorner.com/article/loop-through-enum-values-in-c-sharp/

[stuck lotus]

tbh if it works with gameobject.add then i have no issue in using that way let me give it a go and do some refactoring

[thick socket]

I was looking through that

couldn't figure out a way to get the output as IconTypes."insertname"

seems to just return name as string or int

which isn't of the Enum type

[leaden ice]

you just cast it

or this example from that article seems to just do it too:

foreach (ConsoleColor color in Enum.GetValues(typeof(ConsoleColor)))
{
  Console.ForegroundColor = color;
  Console.WriteLine($"Foreground color set to {color}");
}```

[simple egret]

If you can, now there's the generic version of this method available

Enum.GetValues<T> returns T[]

[leaden ice]

ooh yeah def use that if it's available^

[thick socket]

foreach (IconTypes icon in Enum.GetValues(typeof(IconTypes)))
        {
            ConsumableList.Add(icon, 0);
        }

this works great thanks 🙂

[idle flax]

Hey, got a quick question. I have a float that ranges from -40 to 150. How do I convert that float to a number between 0.0 to 1.0?

[civic fern]

guys i just did a lot of stuff in play mode is it possible to save everything i just did without losing it when i exit play mode

[leaden ice]

Mathf.InverseLerp

[dim spindle]

Ok im gonna ask again, because I really want this to work. Is there any reason a raycast would work differently on windows VS. linux? I have a system that im trying to make to pick up items in my game, for some reason, when I make a raycast at the exact same position (as in "Ray Created: Origin: (401.40, 3.38, 420.94), Dir: (-0.15, -0.37, 0.92)"), it works on two different windows machines, and my editor, but not on linux. any reason why?

[idle flax]

Thanks!

[dim spindle]

btw my ray IS still hitting stuff

just not what i expect

if i cast the same ray beforehand without filtering, it hits stuff, just never hitting the item that im trying to grab

maybe there is a way to render a ray in the game?

that would be useful for debugging

[solemn raven]

hi ,
could someone explain to me what im doing wrong in a simple math equation ?

float initial = 0;
float final = 0 ;
float additional = 5;

final = initial - additional;
/// final is always = 0
// expected value for finale = -5;

does the above equation make sense ? or did i do something wrong else where ?

[maiden breach]

the problem is somewhere else

[dim spindle]

for example how you are checking the value of final

did you Debug.Log it

[leaden ice]

Looks like it's -5 to me
https://dotnetfiddle.net/zNVxSV

[solemn raven]

yes, i debuged all of them

[simple egret]

Looks good to me, C# hasn't lost its mind yet

[leaden ice]

show your real code 😉 @solemn raven because something else is going on here.

[dim spindle]

can you show how you printed them

[civic fern]

do you guys have your animations code all in a seperate script or do you leave it in ur movement script

[dim spindle]

btw for the 3rd(?) time now here is the code for this

public void Pickup_Pressed(InputAction.CallbackContext ctx)
{
    Debug.Log($"Pickup Press: {ctx.performed}");
    if (!ctx.performed)
        return;

    RaycastHit hit;
    Ray ray = main_camera.ScreenPointToRay(Mouse.current.position.ReadValue());

    Debug.Log($"Ray Created: {ray.GetPoint(0f)}, {ray}");

    Physics.SyncTransforms();
    if (Physics.Raycast(ray, out hit))
    {
        Debug.Log($"[Test] Ray Hit An Object: {hit.transform.gameObject.name}");
    }

    Physics.SyncTransforms();
    if (Physics.Raycast(ray, out hit, inventory_grab_range, mask)) // Do a Raycast with only layer 8 (Items)
    {
        Debug.Log($"Ray Hit An Object: {hit.transform.gameObject.name}");
        Transform hit_transform = hit.transform;
        GrabItem(hit_transform.gameObject);
    }

    Debug.Log("Cast Attempts Done.");
}

the first print always runs

and the second one

and the third one

but not the fourth

[stuck lotus]

ok yh this works and things did sort of do what they should have thanks dude

[dim spindle]

also that Physics.SyncTransforms() call is added as a debugging measure as suggested by someone here

if you are wondering about it

but I havent figured out any reason that this shouldnt work

[solemn raven]

Thanks actually 😄 😄
i was writting down the function on discord , then it hit me, i was actually changing the value of _final not final , that is why its always 0 😄
thank you ❤️

[dim spindle]

its like the hitbox on my items just is smaller with linux but that makes actually no sense

and SOMETIMES i do hit the item

just 99% of the time not

[wintry schooner]

I have a transform hierarchy like so: Parent - Child - ChildChild. When I call ChildChildTransform.Rotate(vector.right, someAmount); everything works as expected, until the Child object also rotates. At that point, my ChildChild object accumulates errors and wobbles around a little (as seen by random values popping up in the y and z axes in the inspector). They can get large enough to be perceptible, which is no good.
To be clear, the Child object basically does the same thing, only it rotates around Y (and is obviously doing just fine).
Any clues as to what could be causing this and how to fix it?

[leaden ice]

what are you trying to achieve

[wintry schooner]

2 independently rotating axes, essentially

[leaden ice]

for what

what is this

FPS controller?

[wintry schooner]

A turret

[leaden ice]

something else?

Keep your own yaw and pitch floats

rotate the objects with transform.localRotation = Quaternion.Euler(0, yaw, 0) and likewise for the pitch on the other object

[wintry schooner]

Hmmmm.

Could work... let me think, quite a few things to consider with that 🤔

Yea, that could work. That potentially has quite a few implications on the rest of my code, but might just be fine. Thanks, I'll see where that leads. Still, curious why that's happening. Any idea?

[molten sandal]

Hi there

I would like to ask an advice

I have this code

void Update()
{
    // Move Forward
    if (Input.GetKeyDown(KeyCode.W))
        moveForward = true;
    if (Input.GetKeyUp(KeyCode.W))
        moveForward = false;
}

private void FixedUpdate()
{
    CalculateThrustForce();
}

private void CalculateThrustForce()
{
    float maxThrust = maxForwardThrust;
    float timeToMaxSpeed = topForwardSpeedTime;

    if (moveForward)
    {
        thrustAcceleration += Time.fixedDeltaTime;
        if (thrustAcceleration > topForwardSpeedTime)
            thrustAcceleration = topForwardSpeedTime;
    }

    if (moveBackwards)
    {
        thrustAcceleration -= Time.fixedDeltaTime;
        if (thrustAcceleration < -topBackwardSpeedTime)
            thrustAcceleration = -topBackwardSpeedTime;
        maxThrust = maxReverseThrust;
        timeToMaxSpeed = topBackwardSpeedTime;
    }

    if (!moveForward && !moveBackwards)
    {
        if (thrustAcceleration > 0)
        {
            thrustAcceleration -= Time.fixedDeltaTime;
            if (thrustAcceleration < 0)
                thrustAcceleration = 0f;
        }
        else
        {
            thrustAcceleration += Time.fixedDeltaTime;
            if (thrustAcceleration > 0)
                thrustAcceleration = 0f;
        }
    }

    float thrust = Mathf.Lerp(0, maxThrust, Mathf.Abs(thrustAcceleration) / timeToMaxSpeed);
    rb.AddRelativeForce(new Vector3(0, 0, thrust * Mathf.Sign(thrustAcceleration)) * thrustMultiplier, ForceMode.Acceleration);
}

Any suggestion to make that code simpler and cleaner?

[wintry schooner]

First of all, use input axes rather than KeyDown and KeyUp

Then multiply those with your thrust and whatnot, rather than doing booleans

[molten sandal]

[jaunty sleet]

Does anyone know how I could draw a custom display in a unity editor I am making? I want to make a window with a scroll bar and draw lines inside it, etc for my level editor

is there something kind of equivalent to a drawing panel I can use? I'm sure you guys have used something like I have when you were learning where you can code to draw shapes, etc on a panel. I'd like to use something like that

[molten sandal]

The GetAxis returns a value between -1f and 1f, right?

[wintry schooner]

Yup

[molten sandal]

kk

[molten sandal]

I need some help here please

private void CalculateThrustForce()
    {
        float thrust = Input.GetAxis("Thrust");
        float thrustDir = Mathf.Sign(thrust);

        thrustAcceleration += (Time.fixedDeltaTime * thrustDir);
        thrustAcceleration = Mathf.Clamp01(thrustAcceleration);

        float thrustAmount = Mathf.Lerp(0, maxThrust * thrust, Mathf.Abs(thrustAcceleration) / thrustTime);
        rb.AddRelativeForce(new Vector3(0, 0, thrustAmount * thrustDir) * thrustMultiplier, ForceMode.Acceleration);
    }```

Can´t figure out how to apply fore forward or backwards

At this line ```haskell
rb.AddRelativeForce(new Vector3(0, 0, thrustAmount * thrustDir) * thrustMultiplier, ForceMode.Acceleration);

[thick socket]

why not use rb.AddForce

[molten sandal]

Because that's in world coordinates

I need to apply the force in local space

[somber nacelle]

AddRelativeForce applies it in local space which is basically the equivalent of AddForce

but surely the "thrustDir" variable determines whether the thrust is forward or backwards

[molten sandal]

If I use AddForce, the force is applied incorrectly

[somber nacelle]

so there shouldn't be anything special you need to do to "add force forward or backwards"

although you are doing some weird calculations with the thrust variable then multiplying it by its sign without first taking the absolute value of the calculations

which of course means when you multiply the negative number by the negative 1 for its sign it suddenly becomes positive 😉

[molten sandal]

Yeah, I am kind of failing there

I see the issue

I am clamping between 0 and 1

I need to clamp between -1 and 1

[somber nacelle]

i mean that's not the only issue

you need to either stop mutliplying by thrustDir or you need to take the absolute value of thrust before doing any of the other calculations

[molten sandal]

Let me explain you what I am trying to get here, I think that will be easier

[somber nacelle]

you don't need to explain, you are only providing a positive value no matter what because of the multiplications by -1 when the value is negative

[molten sandal]

can you show me which line is wrong?

[somber nacelle]

my dude what do you think a negative number multiplied by -1 ends up being?

[molten sandal]

sorry lol, I am very mentally tired rn

[somber nacelle]

then take a break and come back to it with a fresh mind

Hey, i have an animator, with an animator state, which moves the transform of my gameObject. However, this animator state is never called, by transition with triggers, or something like that, but, my gameobject has his positions completely frozen, i cannot move it, can someone help me? :/

coding channel...hard to help with code without you posting any 😄

ok, i have this animator :

but the transition from emptyState to SwitchPhase, is never called

i debug.log the code and check , and never called

[grizzled needle]

Does a struct return a copy of itself or a reference when used as a property { get; private set: }?

[lucid valley]

copy

[grizzled needle]

Gotcha, is there a way for me to have to return as a reference?

[lucid valley]

I don't think the Unity C# version has access to ref fields

[leaden ice]

use a class

[lucid valley]

you'd have to make a ref return method (i think, i've not tried) or use a class

[grizzled needle]

If I use it as a class, then it would be open to change public variables within

[lucid valley]

or just remember to set the variable back after you change it, don't make it private set

[grizzled needle]

I want the public variables inside to be protected instead of just the parent class/struct

[leaden ice]

don't make your variables public then

I don't see what struct vs class has to do with that

[lucid valley]

public class Test
{
   private TestStruct testStruct;

   public ref TestStruct TestStruct => ref testStruct;
}

public struct TestStruct
{
        
}

This should work

[grizzled needle]

Ill explain in 1 sec

[grizzled needle]

That doesnt work with my situation

[leaden ice]

It can always work. Expose what you need via carefully curated public methods and properties. Make everything else private

[grizzled needle]

I have a struct that holds a bunch of parameter variables for a director/manager class, the structs are presented as a variable in my director class that are exposed as private set properties so that I can read these variable at anytime while also having them change as i need them from within the director class

A struct works perfectly for my needs, the only problem is that i want to access these variables without forcing a copy of them every single time I need to

[leaden ice]

What's a "struct class"

[grizzled needle]

Real

[leaden ice]

use a class not a struct if you want to pass references around rather than copies.

What are you gaining by using structs here exactly that you don't want to give up?

[grizzled needle]

I have two groups of variables that I need constant global access to, like static variables, but they need to be changed exclusively by the director class and nothing else

[leaden ice]

Three options for that:

• When you want a "view only copy" of your object create and return a fresh copy, not the original.
• Make your class implement an interface that presents its data through read-only properties. Return your object as that interface instead of the concrete type when asking for the view-only copy.
• Make your class contain a struct. Pass the whole class reference when you want to be able to modify it. Pass around only the struct (copy) when you want just a view.

[grizzled needle]

Ah, an interface for the struct is probably what Im looking for

[leaden ice]

for example check out https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.ireadonlylist-1?view=net-8.0. If you return a list as this interface somewhere, then the caller can read the list but not mutate it

[grizzled needle]

If i typecast a struct into an interface, does it still create a copy of that struct?

Or can i do (IStructVar)(ref structVar)

[leaden ice]

The point is to use this in conjunction with a class not a struct

so you know you have a reference not a copy

I have a CardEntity that is created from a CardModel SO whenever a card comes into play (e.g. added into your deck). I'm now getting around to writing methods to render the card on screen, control its animations, interactions with the user, et cetera.

In previous games, I've sort of just stuffed everything inside MonoBehaviours with no real separation of concerns. I'd like to get out of that habit, but I'm struggling to figure out the soundest way to design this. My first instict is to create a separate UICardController that would live on a prefab, and have a method that lives on a factory class somewhere to create an instance and return the UICardController. I'm in doubt on if that's a solid approach though, and wanted to see if anyone had any wisdom to share 🙂

[grizzled needle]

Gotcha, thanks for your input!

[dim spindle]

does really noone have a clue on this? would i be better off asking in #⚛️┃physics ? i cant find anything on google about hitboxes or rays behaving weird on linux maybe im just stupid

[remote lion]

Hello there, i have been wandering and searching for an answer but i can't find it, so i'm here to ask if it's good practice to use the method "Sigletoon" to change scenes or levels or is there a better way to doit.

[hexed pecan]

Linux users are a rare breed so dont expect to get answers quickly

[dim spindle]

i mean i guess

[hexed pecan]

Bumping your question is fine though, and yes ask in #⚛️┃physics why not

[stable rivet]

I assume by method "Sigletoon" you mean create a Singleton with methods to change scenes? If so - you're basically doing what the SceneManager does, just use that

[remote lion]

Yea that's what i wanted to know, thanks (also for correcting me)

        {
            _enemyList.Remove(go);
            PlayerUI.Instance.SetZombieRemainingText(_enemyList.Count);
        }

We dont need to check for contains ? So we forget about it and remove directly ?

[somber nacelle]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.remove?view=netframework-4.8.1

This method also returns false if item was not found in the List<T>

[velvet quartz]

Euh ok but what that will change ?

_enemyList.Remove(go); will not occur a bug if the go don't exist on the list

[somber nacelle]

correct, because it just returns false instead of throwing an error you don't need to check if the item is in the list before removing it

[velvet quartz]

So for performance we don't do the check

[somber nacelle]

unless you need to know whether the item is in the list for some other logic, then you do not need to do that check

[velvet quartz]

ok ty.

I have WebGL game. Iam trying to save game with playerprefs and storing string of JSON. My Weapon class has Sprite icon which it gets from ScriptableObject who has reference to the sprite. How can I save and load sprite with JSON? I saw Resources folder which really messes up my structure of files. I saw storing sprite into raw texture and will be my next attempt but I would really like to hear if there is better way?

Also if somebody has better idea to save progress? I would really like to hear it. If playerprefs becomes problem and can't store so much info I think ill store files at persistentDataPath

[queen mango]

Hello
I do button for pause game
When I click it the timescale = 0 and menu show
But if I click the button behind the menu I can do that
How can I solve this?

[leaden ice]

Probably the obejct already has such a component or another Graphic

[leaden ice]

Seems like a #📲┃ui-ux question

[queen mango]

OK

[stable rivet]

AFAIR, Unity throws an exception if you try to add an existing component

[leaden ice]

nope

just returns null from AddComponent

btw in general you can add duplicate components

but there are certain that you can't. For example Graphic and Rigidbody

for those - it returns null

[stable rivet]

oh right, i stand corrected

                break;
            }

Goal is to spawn enemy on a spawner. What do you think of my script and how you will do it ?

[lost dove]

@leaden icethank you!!

[slim mason]

how can i interact with ui while my cursor is locked?

[fluid lily]

tab or dirrection arrows are a good option

if you camera is rotating then the cursor is still in the center.

another option is to enable cursor movement while UI is up.

[slim mason]

ill see if i can do a ui panel sort of thing

[fluid lily]

Is there anyway to add options to that menu through extensions? I need a SwithActive() Method there, to just switch it from active to deactive, and visa versa

I know I could add my own component to have this functionality, but it is so basic that I would just want it everywhere.

[quartz folio]

I have no idea if extension methods appear in that list, but you could try it and see

[fluid lily]

Yeah no, which I guess I could have forseen from Unity

[wide ermine]

adsRotation = -Quaternion.LookRotation(transform.InverseTransformDirection(gun.GetSight().forward), transform.InverseTransformDirection(gun.GetSight().up)).eulerAngles;

combined with

float adsCurveValue = adsCurve.Evaluate(adsWeightLerped);

arms.localPosition = adsPosition * adsCurveValue;

aiming down sights while an animation is playing (like reload animations) makes the viewmodel go abolutely crazy

[quartz folio]

Is looks to be using assembly definitions (I imagine in the Runtime folder) can you check that that's configured correctly?

Records use properties, and their fields are readonly so they are not serializable. So they are not capable of being displayed/saved without a custom setup.

[viral cipher]

Hello!

I am attempting to make a platformer type game for a game development class at my high school. I noticed that on the school computers, the game's physics were much floatier than on my home computer.

I was wondering how to fix the problem without changing the massive amount of code I have; re-writing it to fit the fixed update loop for ONLY the physics, and having the update loop only for inputs (since it seemed like a lot of work for the fixed update loop to just fail and go over the physics stuff twice)

TLDR:

I essentially have everything in an update loop, and don't want to have to reformat literally all code for every physics-influenced object

Extra question:

Can I technically make this work by proportionally setting the masses depending on the time seen within Time.deltatime?

[rocky dirge]

are you handling physics manually or using rigidbody?

[viral cipher]

rigidbody

[rocky dirge]

and the forces/accelerations you are applying are frame rate independent?

[viral cipher]

I am not using Time.deltaTime, nor Time.fixedDeltaTime, no

so I don't think so

[cosmic rain]

You wouldn't use it for forces anyway. But they need to be applied in fixed update if you want deterministic behaviour.

So just move the parts where you add forces, to fixed update.

[rocky dirge]

they might be using ForceMode.Impulse or .VelocityChange tho

which will need to be multiplied by Time.deltaTime i think

[viral cipher]

I'm using ForceMode2D.Force

[rocky dirge]

just try this then

[cosmic rain]

Depends on what behavior they expect, but normally you wouldn't use delta time for that either.

[viral cipher]

problem: the part where I add forces is tied to my inputs, and I don't want to sacrifice input consistency

pain.

[cosmic rain]

I don't understand what the problem is..?

How is it tied?

Is it using the new input system or something?

[viral cipher]

no

so like, I'm using conditionals each frame to check for inputs.

then based on that, I add a force

[cosmic rain]

Okay..? Then just cache the input conditions and use them in fixed update.

[viral cipher]

alright

*pain intensifies

lol

[viral cipher]

Also, could this technically work? I'm just wondering just in case someone knows

[cosmic rain]

No. It's a terrible solution.

[viral cipher]

alright

fair enough

[cosmic rain]

The actual solution is very simple with a bit of refactoring.

[hexed pecan]

You can get continuous inputs in FixedUpdate, its not a problem.

At least if youre polling like with GetAxis or whatever the new system uses

[viral cipher]

I'm using Input.GetAxisRaw and Input.GetButtonDown a lot

I'll probably just store the values of the inputs in variables for the fixed update loop to use and reset each time it updates

idk

At least thats what I got from dlich

[hexed pecan]

GetButtonDown must go to Update yeah. But if you use it to add a one-shot force (like a jump with ForceMode.Impulse), you can add the force directly in the Update function, it will get applied next physics step anyway

[viral cipher]

oh

so I just need to modify the force values a little bit

with ForceMode.Impulse

[hexed pecan]

You don't really need to modify it at all (assuming youre doing something like if(Input.GetKeyDown(jumpKey) rb.AddForce(jumpForce, ForceMode.Impulse);)

But continuous forces you should do in FixedUpdate

[viral cipher]

ok

[cosmic rain]

You don't need to reset anything I think

[viral cipher]

ngl I dont know how continuous forces are even set up

I'm just calling the addforce once, and thats about it

[hexed pecan]

With continuous I mean something like walking, which gets called potentially every frame and is time-dependent

Don't use ForceMode.Impulse with those btw

[viral cipher]

yeah I won't

I'm just using velocities for that

and, I think I definitely need to change the force value for Impulse mode

since I just used it, and my character jumped straight off the screen, lmao

[hexed pecan]

This good old chart explains how forcemodes work
https://i.redd.it/6y8myu3ruxo71.png

[viral cipher]

so how would I make my impulse the same as the force-mode?

without using Time.deltaTime?

[hexed pecan]

Never use deltaTime with forces

[viral cipher]

I understand that

[hexed pecan]

Oh you would just give it a smaller value

[viral cipher]

idk ill just mess around with some stuff

[hexed pecan]

Like around 50x smaller value

[viral cipher]

yeah

ok, will do. Thank you so much!

[swift falcon]

can i ask a question?

[cosmic rain]

No

womp womp

[hexed pecan]

1 question per person and you just used it for this?

[viral cipher]

lol

[swift falcon]

haha

[cosmic rain]

If you learned the lesson, go ahead and ask your question

[swift falcon]

how would you go about detecting the bottom half of a collider?

[cosmic rain]

Detecting in what sense?

[hexed pecan]

When colliding or what?

[swift falcon]

say a raycast hits the top half/bottom half with a seperation in the middle

to detect something like feet/torso or will i have to make seperate colliders

[hexed pecan]

You could convert the hit position to that object's local coordinates, and check its y

But multiple colliders would be more intuitive IMO

[cosmic rain]

Ideally, you'd make separate colliders(probably triggers) for the bones.

Often, if you have a ragdoll setup, you'd use the ragdoll colliders for that.

[swift falcon]

ty

if(hit.point.y > hit.transform.position.y ) {
}

this is working

[grizzled needle]

Is there a way to typecast a SerializedProperty into a custom class like TestClass or something? Or at the very least edit its values like TestClass.value and apply it to the property through the editor using a custom editor class?

[stoic plume]

Hi!
Does anyone know why my AudioSource is being removed when I go in "Play Mode"?

[somber nacelle]

something is probably destroying it

[leaden ice]

MyClass example = (MyClass)myProp.boxedValue;

You can also use FindPropertyRelative to get its serialized fields

[stoic plume]

Did you answer my question or someone elses?

[somber nacelle]

yours

[stoic plume]

Do you know what might be destroying it?

There's no "Gameobject(destroy)" hooked on any script

[somber nacelle]

considering i've not seen your project or your code i have literally no way of knowing

[leaden ice]

Most likely your code

[stoic plume]

Can you please check what it is?

[leaden ice]

Different code

[stoic plume]

It's only this code

[grizzled needle]

Thanks! In order to reverse it after I make any changes, do I just do myProp.boxedValue = (object)example;?

[leaden ice]

I'm sure you have other scripts in your project

[somber nacelle]

is the issue actually that the reference in the inspector is being set to null and not that the audio source itself is being destroyed?

[leaden ice]

If you want to make changes it's usually better to do it through the serialized properties

[quartz folio]

Also that OnKeyDown will not trigger consistently https://unity.huh.how/programming/input/built-in-input/input-in-fixed-update

[stoic plume]

Alright, so [SerializedField] instead of public?

[somber nacelle]

if i was right about the issue that likely isn't going to change much. you'd need to remove that line from Start since the object clearly doesn't have an AudioSource component attached to it

[rocky dirge]

check if audio source and scriptffs are actually on the same gameobject

u may have component ref assigned but set to null in start

[stoic plume]

That fixed it! Thank you so much

All of you I should say

[marble halo]

So im trying to make ladder climbing and i have this value that determines which direction you climb in depending on where you are looking

the problem is, if the direction you are looking in is the center (aka 0) you stop moving

Is there a way to make it so that a float is never 0?

Mathf.Round(player.cmPosition.forward.y)

heres what determines where you move

Vector3 direction = player.transform.up * Mathf.Round(player.cmPosition.forward.y) * player.currentinputvector.y; //allows player to climb up or down depending on where they look

IDK how to describe it

[somber nacelle]

round it on another line, then you can use a ternary or if statement to check if the value is 0

[nimble salmon]

I really need some help understanding why my mesh with procedurally generated vertices doesn't work in prefabs. I have this setup:

• GameObject
  • TextMeshPro
  • Quad

The GameObject has my script TextWithBackgroundController, which holds a reference to the TextMeshPro and the Quad. In its Update, it changes the Quad's vertices via quad.GetComponent<MeshFilter>().mesh.vertices in order to create a background for the TextMeshPro. This works perfectly in both play and edit mode.

Now, I'd like to make a prefab out of these three objects. When I do so, and spawn a new instance of that prefab, the mesh doesn't render at all. The debugger shows that the vertices are set correctly, but that there are no triangles.
I can fix the issue by manually going into the new Quad, and changing the mesh from "Quad" to "Quad Instance" in the mesh filter component.

I don't get it at all. Why does the prefab not render? Why does the mesh not get saved in the prefab? Why does changing the mesh manually fix the issue?

The source code for my script is here: https://gist.github.com/vittorioromeo/d500c347465f5cc3555001d00a1dd6cc

This is really driving me nuts, I don't understand this behavior at all.

[marble halo]

if (collision.gameObject.TryGetComponent(out IDamageable damageable))

I do this for apply damage to a target but some target are friendly and so can't damagable between then how you can know if you can damage the other target or not ?

[worldly hull]

this may be an advanced question, is there a way to know how many size that a specific API/package occupied in built app?

[leaden ice]

Well for one you're not assigning any triangles to the mesh.

For two, kinda struggling to understand the point of this script. Couldn't you just use a world space canvas with a Content Size Fitter to do this more easily?

[leaden ice]

Not really a code question but https://docs.unity3d.com/Manual/ReducingFilesize.html

[worldly hull]

thx

[nimble salmon]

The part I don't understand is that the are triangles in the original mesh that I am creating the prefab from. Why aren't those being copied over to the prefab?

[woeful spire]

currently getting pissed off at the TrailRenderer for emitting even though it shouldn't be (I'm probably wrong somewhere I hope).
I wrote this as a workaround 'cause apparently the .emitting value needs one frame before it affects the trail.

private IEnumerator StupidOneFrameWaitCauseTrailRendererSucks()
    {
        trail.emitting = false;

        yield return null;

        currentAnimation = StartCoroutine(AnimateFromTo(GetIndex(), ContinueAnimation));

        yield return null;

        trail.emitting = true;
    }

This should wait a frame after disabling emitting, then teleport it, wait one more frame - then finally emit again.
What ends up happening is the code sometimes working, as the picture shows.
The dead end up top is a successful jump, while the line from the bottom to the middle was a not-so successful one. Any ideas?
