[tiny vault]

thank you SO much!

[ivory bobcat]

Place some logs to see if you're actually getting input

[ivory bobcat]

Did it enter the if statement?

[dense anchor]

yeah everything works execpt _rb.linearVelocity = new Vector2(0f, _rb.linearVelocityY);

[keen dew]

The most common reason is that the normal movement code also sets the velocity directly which overrides the dash velocity

[ivory bobcat]

Doubtful. Those statements don't do anything special - no variable failure possible.

Either the statements aren't ever reached, velocity is changed elsewhere, rigid body isn't in the physics simulation or etc

[keen dew]

Also that line is what stops the dashing so if the problem is that it doesn't dash at all then that line isn't the problem

[dense anchor]

i stopped the movement when dashing but it's still not working

    if (_dashSc._isDashing == false) {
        _rb.linearVelocity = new Vector2(_movespeed, _rb.linearVelocityY);
    }

[ivory bobcat]

Is dash duration zero?

What about dash direction and speed?

[dense anchor]

it works i just changed the _dashdir = movedirection to flip face

and also i stopped walking when dashing

[kind skiff]

I have a very wierd bug that happens with the layer

So I have a projectile

When I put it in other layers

The effects around it will not appear

And when I put it inside the default layer

It just magically appears

[silk comet]

does anyone knows a bit on photon and ml-agents? I would need help with a little but deadly problem in my "game"

[civic cradle]

Hey friends,
quick question:

I'm setting up a small quiz-game for a local network.
WebSockets and stuff like this are working already, but I don't know how to add the connected player to my text-canvas.

I think it has something to do, that the TextMeshPRO isn't in the update-method, but I wasn't able to find a redraw() or something.
Please, have a look at this:

    public class ChatBehavior : WebSocketBehavior
    {
        protected override void OnMessage(WebSocketSharp.MessageEventArgs e)
        {
            // check if it is a connecting player
            var payload = Newtonsoft.Json.JsonConvert.DeserializeObject<MessagePayload>(e.Data);
            var username = payload.Username;
            var type = payload.Type;

            // add player to list
            GameObject.Find("PlayerList").GetComponent<TextMeshProUGUI>().SetText(username);
        }
    }

is it because I'm not referencing MonoBehaviour in this?

[grand snow]

its .text to change the text but why are you using Find() each time... use [SerializeField] to have the tmp text reference or find it on Awake/Start.
If you want to "add" the name you can do .text += username or keep a list of all usernames and re construct the whole text on each connect/disconnect.
https://docs.unity3d.com/Packages/com.unity.textmeshpro@1.0/api/TMPro.TMP_Text.html#TMPro_TMP_Text_text

[civic cradle]

i know that. This is something else I have to make nicer anyway. Right now I'm simply lost on why it doesn't update the text.
I think it has the correct value, but it isn't displaying it.

Whole code.
https://paste.ofcode.org/Wz7r4iUyvtJPxMxreibQxm

I'll adjust to make use of SerializeField now, though. Gimme a second

I think part of it is also the fact that I have multiple classes in one file

[teal viper]

Wdym by "add the connected player to a text canvas"?

[grand snow]

if you have more than 1 monobehaviour in a file it wont work properly or at all

[teal viper]

One possible explanation is that this code is running on a background thread and unity does not allow that API to be called on a background thread.

[civic cradle]

i mean, I have a GameObject called "PlayerList". This PlayerList has the TextMeshPRO-component.
onMessage() i want to add the playername (taken from an external form-element) in my GO to display it on screen

[languid spire]

If you only 'think' things are correct why have you not debugged your code?

[civic cradle]

I tried, but everytime I set my breakpoint the IDE crashes. not unity in general, only VS 2022 🤷

[swift crag]

what is a WebSocketBehavior?

hopefully no relation to MonoBehaviour

[languid spire]

Then use Debug.Log

[grand snow]

move ChatBehaviour into a new file (its current defined inside of the other class...)

[swift crag]

That's fine, as long as it's not actually a kind of unity object

it appears to be a class from the webshocket-sharp library

[grand snow]

if vs is crashing could be some dumb old mono thing

[civic cradle]

I'm not sure if I might post links, but it is a lib from github:
websocket-sharp/

[civic cradle]

exactly

[swift crag]

I would at least verify that the method is running at all

[swift crag]

I could believe this.

[civic cradle]

which method? I mean, I verified that it hooks correctly. I can post my WS-messages from my javascript file and unity (the logger) does display stuff

[swift crag]

the method that tries to display the player's name!

[teal viper]

I bet they have an error or a warning about this in the console as well...

[grand snow]

That is true, unity will throw an exception if this happens (using the unity api on another thread) and this is NOT logged in editor, only debugging will let you know this

[civic cradle]

(roughly translates: message recieved: {"Username.....}

[civic cradle]

no warnings, no errors

[swift crag]

you need to prove that OnMessage is running

it doesn't matter if some other unrelated thing is working

[civic cradle]

this logging from the screenshot above is placed in onMessage

[swift crag]

Ah, so you just added that

[civic cradle]

no

that was there the whole time

[swift crag]

   // Verhalten für den WebSocket-Endpunkt
    public class ChatBehavior : WebSocketBehavior
    {
        protected override void OnMessage(WebSocketSharp.MessageEventArgs e)
        {

            // check if it is a connecting player
            var payload = Newtonsoft.Json.JsonConvert.DeserializeObject<MessagePayload>(e.Data);
            var username = payload.Username;
            var type = payload.Type;

            // add player to list
            GameObject.Find("PlayerList").GetComponent<TextMeshProUGUI>().SetText(username);
        }
    }

I am talking about this method.

[civic cradle]

oh, yea. agreed. i got rid of that

[swift crag]

Prove that it is running.

[civic cradle]

i removed the loggers to keep the code simple

[swift crag]

Don't do that.

Show us the code you are running

[teal viper]

Never do that when asking for help

[civic cradle]

will keep that in mind. I really thought I would only show the relevant parts. But you are right, that made a hickup where it didn't have to be one

one second

[swift crag]

If you knew what was relevant, you would have solved the problem already (:

[thin birch]

Can I ask a question related to the screen resolution? I would like my game to build at a square resolution (960x960) and if possible be risizable but remain at a square ratio... Is this possible?

[teal viper]

Knowing how you debugged so far is very relevant.

Anyways, I still bet it's due to it running on a thread.

[civic cradle]

https://paste.ofcode.org/72wypadAWC6jXWRammtgD5
this is the complete, unmodified code, including german comments and debug-lines

[swift crag]

well, now it doesn't set the text at all!

that'll sure slow you down a little..

[thin birch]

if it's of help Im using unity 2022.3.47f1

[civic cradle]

updated the paste. Please press F5

[teal viper]

Probably. I think you can set the resolution somewhere in the project settings - player settings.

[civic cradle]

and this is the GO I'm talking about

[thin birch]

I'm trying but nothing seems to work

[swift crag]

it did not change

[grand snow]

windowed or full screen?

[civic cradle]

weird, should have

[teal viper]

I think you'll need to share the new link.

[civic cradle]

https://paste.ofcode.org/35ees4aR2MYGM9itEJm7msD

[swift crag]

yeah, i presume it generates a new path

[civic cradle]

yea, thought "edit" might save the url

[thin birch]

putting it as fullscreen mode: windowed and set it to 960x960

opening it the game is fullscreen as if it wasnt set

[grand snow]

I will laugh if username is ""

[swift crag]

You should ensure that username is not an empty string

[civic cradle]

no, it isn't. Let me show you something real quick

[swift crag]

I know that "Username" appears in the JSON

[civic cradle]

as well as in any debug-log i had prior. I isn't in the code anymore, agreed. But I verified the username as well as the type.

[swift crag]

but when software is not working, you must verify every assumption you're making

[teal viper]

Assuming it prints Nachricht empfangen: something and there are no other warnings/errors, then it should work. If it doesn't, it's likely due to it running on a thread.

[civic cradle]

it does. Let me see if I can make a quick screen-capture real quick

[grand snow]

May be good to test setting the resolution yourself and see what it does. I would presume windowed + borderless windowed fullscreen will support any res but exclusive fullscreen may not:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Screen.SetResolution.html

[civic cradle]

maybe easier to visuazlize it

[thin birch]

oh it fixed itself lmao

[swift crag]

I do see a ThreadPool in the library's source

[thin birch]

2nd thing it fixes itself in 2 days after restarting it a bunch of times

[swift crag]

If this is the problem, then I would consider pushing the parsed messages into a queue that is then processed in an Update method somewhere else

[teal viper]

It's a library non related to unity, so of course it's gonna receive messages on a separate thread.

[thin birch]

will look into this for reference tho!

ty

[grand snow]

ConcurrentQueue is a good choice for this!

[grand snow]

reference the tmp text via a serialized field and use .text to make 100% sure its going where you wish...

[civic cradle]

will do

[grand snow]

if all else fails delete and make a new tmp text and assign that and pray it makes it work. I use tmp ugui text all the time but havent seen this myself.

[civic cradle]

i mean, I would assume that since it isn't placed in the update()-method, the TMP simply isn't rerendered.
I could also try to retrieve the text from TMP after setting it and log it. That way I could at least verify, that the TMP holds the correct value.

Because if it does, I would assume the redrawing isn't happening, which makes sense, because why would it

[grand snow]

no changing the text will make it re draw

if the text is changed, it will set an internal dirty flag to re build the mesh

[civic cradle]

good to know

[grand snow]

Ideally you would use a debugger to confirm the text property changes correctly

[civic cradle]

on it

interesting 🤔

 // this here is logged
 UnityEngine.Debug.Log($"Username is: " + username);

 // this isn't
 UnityEngine.Debug.Log("Current Value of TMP: " + GameObject.Find("PlayerList").GetComponent<TextMeshProUGUI>().text.ToString());

 // add player to list
 GameObject.Find("PlayerList").GetComponent<TextMeshProUGUI>().SetText(username);
 
 // this isn't either
 UnityEngine.Debug.Log("Current Value of TMP: " + GameObject.Find("PlayerList").GetComponent<TextMeshProUGUI>().text.ToString());

no warning of a null-reference or similar as well. not the static text in the Debug-Log either (Current Value of TMP...)

[languid spire]

NRE in Console?

[teal viper]

I think find and get component would fail on background thread. Though I did expect there to be an error at least.

[civic cradle]

no error, no warning

[languid spire]

they will indeed

[civic cradle]

but yeah, that explains it then

[grand snow]

😠 remove Find()

[civic cradle]

i will, i have to restructure it anyway, since I don't want 2 classes in one file

[languid spire]

Cannot use Unity methods on anything but the main thread

[civic cradle]

okay, so to keep thins cleaner then: I simply add my player to a queue or var and make the stuff happen in update() then. That should do the trick.
Basically, onMessage --> call method to add User(name) to a variable and in Update keep track of this var.

That way I can have these things capsuled as well and don't mix them together.

[grand snow]

When i last worked with other threads in unity i had to have a debugger attached all the time to break on exceptions so i could be notified.

you can use ConcurrentQueue<> to queue up the recieved messages and parse + use them safely on the main thread (if this is even the cause as you have not confirmed this correctly)

[civic cradle]

Let me clean up the code and verify it. I'll also get rid off find

[languid spire]

you need to get rid of the Find and the GetComponent

[civic cradle]

Maybe unity is also a bit too much for a game similar to you don't know jack

i was initially supposed to be a very very simple gimmick for new-years evening, where people simply open a url in on their phones and get yelled at from some TTS in combination with chatGPT. Then again, can't hurt to at least deepen my understanding of unity when I'm trying to do it this way

[grand snow]

Find() is okay when you start learning but better solutions exist to better reference components, gameobjects and assets

[languid spire]

tbh using Websockets in Unity is pretty trivial when you roll your own code, I'm guessing the problems are coming from you using a library which was designed for 'standard' .Net apps

[civic cradle]

all right:
i cleaned up a bit, but ended up with warning:

WebSocketServer.cs

// check if it is a connecting player
var payload = Newtonsoft.Json.JsonConvert.DeserializeObject<MessagePayload>(e.Data);
var username = payload.Username;
var type = payload.Type;

GameManager gameManager = new GameManager();
gameManager.playerAdd(username);

GameManager.cs

public class GameManager : MonoBehaviour
{
    [SerializeField]
    TextMeshProUGUI playerlist;

    /* empty start and update methods */ 

    public void playerAdd(String playername)
    {
        playerlist.text = "abab";
    }
}

resulting in:

You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be added using AddComponent(). Alternatively, your script...

I also tried making the playerAdd() function static

[languid spire]

So make GameManager a Singleton and add it to an empty gameobject, then you wont need the new()

[civic cradle]

all right

interesting. so it does indeed call the corresponding function. it does log my input as well, however, it is still not updating the text-value,
which makes me think that there is something else going on

[sterile radish]

hi, i'm trying to make a random weight system to spawn different platform types for my game which is a doodle jump clone. i was thinking of having a gameobject array of all possible platform types and then spawning a platform from that array based on the rolled weight. however, i also want to take into account the players height (for example, if the player just started playing and they have a low height, i dont want to start summoning all the different types of platforms) how would i implement this?

https://paste.ofcode.org/qJUvU6e9nxMBfiVDD6XPrW

[civic cradle]

maybe something like an array, as you said. Start with 2 plattform-types. upon reaching treshhold 1 (lets say 20m) you push another type into that array. Beginning with the next iteration, it would take a random out of now 3 possible plattforms

[naive pawn]

probably calculate the weights based on a floor, ceiling, and the player's height

[civic cradle]

one last attempt, otherwise I'll let it go:
https://paste.ofcode.org/FUfWfL8XfpsewQ2KMyemrz
So, as suggested, I tried this very basic thing:

In my start()-method, the text is set correctly. It is also re-drawn as expected.
However, it doesn't do anything (except logging) in my addPlayer()-method

[grand snow]

you don't need to access the static reference from a member function but if it doesnt do anything still then put a breakpoint and see what happens (check .text before and after) and make extra sure you arent changing the text state again elsewhere.

if VS doesnt work you can try vs code but install the new unity vs code extension + update the vs package in your project

[civic cradle]

it is correct beforehand. it is like it is "failing to achieve to do anything" there

the second Log (#43) i also not displayed. No Error, no warning

I know that I don't know to access the static ref, but trying go get a clue on this. this very same code DOES work in start()

as if there is some kind of return or something, that prevents the code afterwards of being executed.
I can only imagine that it is a problem that I'm calling this method from another script

[grand snow]

if it never logs is probably the other thread problem. if you enable breaking on all CLR exceptions you VS will break and show you when this happens.

[civic cradle]

it logs the first line though

[grand snow]

oh, are any of those things on line 42 null?

[civic cradle]

I can't imagine it, since it is the very same code from start. so Instance.playerlist is bound to the script via [SerializeField].
I'll double check if it is null though

[languid spire]

try this

string text = null;
void Update()
    {
        if (text != null) {
           playerlist.text = text;
           text = null;
        }
    }

    public void playerAdd(String playername)
    {
        Debug.Log("added player");
        text = "called afterwards"; 
    }

[grand snow]

this technically isnt thread safe

[languid spire]

just a test, proof of the problem

[civic cradle]

: o

that works

[languid spire]

I thought it might. So you can use the same construction using a thread safe collection like ConcurrentQueue

[civic cradle]

but before I dig into concurrentQueue - why does this work now? Why is this different to my approach?

[languid spire]

becauae playerAdd is being called from another Thread and updating the TMP.text is running stuff not allowed off the Main Thread

[civic cradle]

we checked that TMP is redrawing after a text-change (as seen in start() ) - why doesn't do that in playerAdd()

oooooh i see

[languid spire]

Start is run on the Main Thread

[civic cradle]

so what we then do, basically, is to simply set the TMP.text in the main-thread again via update and we simply adjust the memeber-var "text"

[languid spire]

exactly

[civic cradle]

all right, thank you guys so much. I'll look into that concurrentQueue now

[naive pawn]

why specifically the check to make it only assign when needed?

[languid spire]

optimization, why do unnecessary work?

[grand snow]

the re assignment each frame would probably re dirty the text (unless they check this internally)

[naive pawn]

i mean i wouldn't think to do that for testing a problem so i thought there was a more specific reason to do it for TMP or somethign 😅

[languid spire]

that's me being me

lol

[naive pawn]

fair enough lol

[swift crag]

As a rule of thumb, you aren't allowed to talk to Unity outside of the main thread

And if you want to talk to anything else, you need to be very careful about thread-safety

(hence using ConcurrentQueue, which properly handles multiple threads trying to interact with it simltaneously)

[civic cradle]

makes total sense

[languid spire]

generally true but I am somewhat surprised the TMP is throwing a hissy fit, I thought it was better than that

[civic cradle]

i was under the assumption that this websocket thing somehow relates to unity

[swift crag]

I was expecting a visible error, at least

[grand snow]

If it was provided by unity or made for unity it would probably not be a problem

and setting tmp text surely interacts with some unity api at somepoint that causes an exception (hence it breaking)

[swift crag]

Eventually, yes

[civic cradle]

possibly i simply relied too much on that lib

[grand snow]

and as i pointed out, if not on the main thread it wont log the exception in editor

[languid spire]

actually the 3rd party stuff Unity buys in is generally of better quality than the code they write themselves

[civic cradle]

in my head, that seemed quite simple, really:
react on a message from a browser (like have a player connect) -> play fancy animation in the game and tell everyone player x joined

[grand snow]

true but why would this suddenly be thread safe? none of unity is except for stuff like the job system

My preferred way to solve this issue is using UniTask: (e.g. often mobile ad watch completion events are fired on othre threads)

async UniTask DoOnMainThread(string playerName)
{
    await UniTask.SwitchToMainThread();
    tmpText.text = playerName;
}

[languid spire]

Somewhat of a sledgehammer to crack a nut, no?

[grand snow]

where i work we make extensive use of async code and unitask so it works great
the ad watch functions are awaitable so it fits well.

[civic cradle]

wait, so in that case, instead of having

public void playerAdd() { }

i would have it like this?

async UniTask playerAdd() { }

and I simply let the call from the other script alone? it still calls playerAdd() with the same argument as before?

[grand snow]

yes but dont go using UniTask or async code if you arent familar with it as it has differences to coroutines.
Using a concurrentqueue is a good solution and safe solution to transfer data/work

[civic cradle]

if it wasn't for the fancy stuff I could do with particles, videos or anything similar, i would simply rely on python or so.

[grand snow]

[languid spire]

@civic cradle Nice to actually solve a problem posted in a code channel lower than it deserves for a change, thank you

[civic cradle]

lol, i have to thank you 😄

[languid spire]

nah, it was fun

[civic cradle]

well not for me lol

that took me like 4h now

[languid spire]

but, next time, you'll know

[swift crag]

well, that'll make sure you remember (:

[civic cradle]

but nice nontheless that it actually works now. at least I learned about this main- and off-thread thing

exactly

[swift crag]

If only I could skip straight to the solution every time

I'd have my game finished in a month

a tool-assisted speedrun

[languid spire]

But then I'd be out of businness

[grand snow]

you guys get paid?

[civic cradle]

the thing is that this stuff demotivated me so much right now. really. having to spent 4h on a task as simple as changing text.
this isn't even something of the stuff I'm more afraid of like networking or distributing data accordingly to every player.
plain, simple text

[languid spire]

not here, but my 'day' job is producing game frameworks for people who want to make a game but can't

[grand snow]

sold on the asset store? I do mobile games for mine (in unity ofc)

[languid spire]

nah, we license direct to publishers and studios, can't do our business model via the asset store

[grand snow]

sounds cool! I recently saw some horrific code from some thing we bought of the asset store 😐

so i have little faith in anything there, thankfully its rare we buy anything with code

[languid spire]

I hate to say it but imo 90% of the code sold on the asset store is horrific

[upper prawn]

How can I save a prefab as a .asset so that I can dynamically load it at runtime? I see there are scripting APIs for saving during runtime, but I want to have them beforehand, and then load them at runtime, almost like a plugin sort of

[languid spire]

just drag a gameobject into the project view, hey presto, prefab

[swift crag]

I see there are scripting APIs for saving during runtime

I'm not sure what you're referring to here

[kind skiff]

Guyss how do I get the previous time? So what i want to achieve here is that I want to get the current time when the button is pressed and then get another time when the button is pressed again then minus the two values to check how much time have passed since the last button press

[swift crag]

store the time in a variable

look at it later

[kind skiff]

I tried this

                startTime = Time.time;

then

Time.time - startTime

But the amount of time i get keep increasing for some reason

[swift crag]

Show the actual script.

[languid spire]

well thats silly
var dif = Time.time - startTime;

but better to use DateTime and TimeSpan classes, that's what they are for

[grand snow]

Time.time seems fine for this as long as you update stuff each time

[kind skiff]

nvm I found out the reason why it didn't work

[swift crag]

notably, if you only set startTime once, it will not behave (:

[frail hawk]

so why was it not working as you wanted

[naive pawn]

probably because they didn't update startTime

[upper prawn]

e.g. this function https://docs.unity3d.com/6000.0/Documentation/ScriptReference/PrefabUtility.SaveAsPrefabAsset.html
But what I'm trying to achieve is using a "manifest" file to associate saved prefabs (really models are all I care about, but it seems like this is the way) to names.
So when I do something like PlantSeed(string seedName), I can lookup the correct model and Instantiate it in the game

[swift crag]

This is an editor method for creating a prefab asset.

[swift crag]

It sounds like you just need a way to load assets at runtime.

The most obvious thought is to use Resources.Load, and this is fine if these prefabs aren't very large.

You can also just store a list of seed prefabs somewhere, of course.

If you have a lot of models, textures, etc. to deal with, you would want to look at using Addressables instead.

(note that anything inside the UnityEditor namespace does not exist at Runtime)

[swift crag]

also, importantly, none of the files in the Assets folder exist at runtime either

you don't load a specific .asset file

[swift crag]

(save for anything in a StreamingAssets folder, of course)

[upper prawn]

I feel like Resources.Load is the best way to go (without knowing much, just thinking about how I've implemented this in the past lol)
I thought I saw that you can't load FBX files with this though, is that not true?

[swift crag]

That is an unrelated question

Resources.Load does not load a file

It loads an asset.

When you put files into your Assets folder (e.g. an FBX), Unity imports them to produce assets

If you put a file into a folder named Resources, Unity will let you load the resulting asset by name

The assets are bundled together into large archives that are included with your game. The original files are not included

At runtime, your game has no idea how to parse an FBX file

Now, there are packages for runtime model importing! But that's a separate thing entirely.

[upper prawn]

Ok I think I'm following. So if I store my prefabs or FBX files in this Resources directory, Unity basically embeds a database of these things.
Then at runtime I could look things up by name. But I -couldn't- modify a text file or add a new model because the directory won't exist at runtime, it'll be embedded in the application

[languid spire]

you've got it

[upper prawn]

Awesome, thanks! I'll eventually want to figure out how to support modding and more things at runtime, but this is definitely good enough to get me going for a long while!

[languid spire]

Modding etc will means Addressables but, that is indeed a whole other topic

Hey @languid spire , I have no code in the project. What I am trying to do is when the Left UI button is clicked it plays the animation

Just realized you said without scripts, not sure you can do that, also this IS a code channel

[languid spire]

never used it but that looks like it should be fine. You are probably better asking in #🏃┃animation

[west radish]

Does that mean this wont work if I built the project? ExampleMaterial = (Material)Resources.Load("mat/Example");

[swift crag]

no, that's fine, assuming you have a material asset named Example

(ideally, use Resources.Load<Material>("mat/Example"))

My point was just that it's not actually finding a file on your computer with that name

[west radish]

ah, gotcha

[swift crag]

It's looking for an asset based on its path

Normally, you can't do that -- you have to serialize a reference to an asset

This lets Unity strip assets from the build if they are not referenced

anything in Resources is auto-included because Unity has no clue if you're going to load them or not

[west radish]

does Resources have to be placed at Assets/Resources or could I do Assets/myfolder/otherfolder/Resources, not that I ever would

[swift crag]

You can have many Resources folders, and they can be anywhere in the Assets folder

check out the documentation for Resources.Load

[languid spire]

anywhere in the path as long as Resources is in the name

[west radish]

oh!

I assumed you could only have 1 folder

[swift crag]

you usually just have one

but other packages may include their own Resources folder for their own use

Name collisions ahoy

[west radish]

mhmm

[languid spire]

you cannot have
Assets/Resources/mat.asset
and
Assets/MyPath/Resources/mat.asset
but you can have
Assets/Resources/mat.asset
and
Assets/Resources/MyPath/mat.asset

[swift crag]

I keep my use of Resources to a minimum. I mostly use it to load "catalogs" of configuration assets. I also store small assets that are associated with classes in there

[west radish]

Resources.Load is such a life saver, in the past the one thing that I've always loathed is getting my code to load a file. The naive approach was always to use some awful system.io and to then have to deal with "how do I get the code to understand where the assets folder is located" nonsense

[swift crag]

well, remember, you are not loading a file

You are loading an asset.

There is no "assets" folder in the built game.

That only exists in the editor.

You might want to check out the section of the documentation that talks about the asset system

it's nice to know wtf is going on in there

[rich adder]

addressables are better 8)

[west radish]

I just mean that before I knew Resources.Load existed, to have the code access a texture or anything, meant I had to use the systems io

[languid spire]

tbh System.IO is a very blunt tool in Unity. UnityWebRequest can do the same thing but is very much more Unity friendly

[swift crag]

Okay, but you're still describing two very different concepts

If you want to load a PNG from the player's computer, that's completely unrelated to loading an asset that you imported back in the editor

Both processes eventually give you a Texture2D object

But you can't substitute one for the other

[west radish]

oh no in the case of loading a file from the users pc, io would be ideal (like if I had some custom levels stored in some %appdata% directory)

but to load a ComputeShader thats located in my project itself, I wouldnt need to deal with any system,IO stuff when I can write TileCompute = (ComputeShader)Resources.Load("compute/TileCompute");

[swift crag]

Yes, and you couldn't do that with a direct file read, full stop

[wispy coral]

do yall know who has good tutorials for everything in unity?

[languid spire]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[wispy coral]

thanks!

[west radish]

surely it could be possible to take the full path M:\UnityProjects\ZenGarden\Assets\Resources\mat\Example.mat and use that to get Unity to read the file

[languid spire]

no

[swift crag]

That does not exist at runtime.

Additionally, just reading that file directly does not give you a ComputeShader. It'd give you...text

[west radish]

oooh, right

[swift crag]

Again: outside of StreamingAssets (which get copied into your built game), nothing in the Assets folder exists in the built game

Those files got imported to produce artifacts, which then get glued together into large asset archives

There is no "Example.mat" file in your built game

[west radish]

I recall in the past trying to put stuff into some appdata directory, because I knew that folder would be created when the game runs, and storing stuff in there meant I could get """""easy""""" access to files that could be loaded in the code

[swift crag]

screaming

[languid spire]

sure, persistentDataPath

[west radish]

I know better than doing anything like this now

[swift crag]

There is the persistent data path

https://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html

This is an appropriate place to store things like save files

I also dump debug data there

[languid spire]

Also, persistentDataPath is the only path where you can use System.IO access on all Unity platforms

[swift crag]

mobile devices are very strict about that

unlike on other platforms, where you can ransomware the entire computer at all times

😉

[west radish]

ive seen at least 3 people over the years ask about doing something really sus with it

[swift crag]

hello how do i encrypt computer, i mean save file

[languid spire]

which is why we do not discuss subjects like this here

[west radish]

one dude was asking how they could get the game to download files to the users pc to get the game to read them, when pushed for the reason, he kept skirting around the answer

[swift crag]

i need some "DLC"

[unborn urchin]

when adding sprite renderer to an object and dragging an image into it, then adding box collider 2d, how come changing the size in box collider isn't changing the size of the picture?

in the tutorial im watching it does

[languid spire]

I doubt it, the 2 are unrelated

[unborn urchin]

thats what i was thinking i didnt know how that worked in the video

https://www.youtube.com/watch?v=XtQMytORBmM 16:47

16:58 sorry

[cosmic quail]

if you change the box collider's size, you're changing the box collider's size. not the picture's size

[unborn urchin]

i get that and it makes sense, but in the video the image just randomly changes sizes

when hes changing the size of box collider not sprite renderer

[magic panther]

I'm making an audio system, but I don't feel like making a bunch of AudioClip variables, so I wanna try to attempt it like this: When a sound needs to be played, I wanna pass in a sound from some kind of directory. I have no idea how I could do that. Like, pass in a AudioDirectory.clipName, it finds the according file by it's path and plays it. What's the best way to go about something like this? Or is this a very bad way to do it, in that case what's the best way for a no variable audio system (No variable as in there's no need for a singleton object with the clips stored in variables or stuff like that)?

[rich adder]

Addressables

[languid spire]

No, you are misinterpreting what you are seeing, all he is doing is changing the collider

[magic panther]

Evaluate please

[floral estuary]

Okay but I get you like addressables haha but it's not gonna get him what he wants

[rich adder]

huh ?

[floral estuary]

Why is it you don't want to reference the audioclips? You can use Resources.Load to do it by name but

[unborn urchin]

when he changed the x variable size to a smaller number, the image got smaller when i do it, the hitbox gets smaller but the image stays the same

[floral estuary]

Addressables are still going to make him assign his variables the same way

[rich adder]

how so?

[cosmic quail]

where does the image change sizes? i checked 16:58 and its not

[magic panther]

yes that's what I mean. All my audio files are in Resources. The problem here is I don't want to change every instance of the function any time I, for example, move a folder with some sounds elsewhere. I need one source spot to do all the setup, assign codenames (or something like that (the .clipName from my message)) and have them read from there

[languid spire]

no it doesn't

[unborn urchin]

17:05

[rich adder]

Addressables are literally Resources.Load but better

[unborn urchin]

mine goes like this his goes like this

[floral estuary]

Oh, well then why don't you want AudioClip variables? That's exactly what that will give you

[cosmic quail]

it doesnt change size for him though. just the box collider. and then he moves the image up

[unborn urchin]

ive never gotten into game design before, ive always just coded. this is all new to me sorry if im slow lmao

[cosmic quail]

its hard to understand from the picture, are you saying your image moves up when you change the box collider's size?

[sterile radish]

hi, im making a doodle jump clone and i have different types of platforms that behave in different ways. i was thinking of creating a seperate script for each type of platform cuz i have only like 3 types of platforms in my game. is that efficient? or is there any way i can optimize this?because all the platforms scripts would look pretty much the same it's just the stuff that's changing in the oncollision method

[floral estuary]

I get that but Addressables is a whole other system. It's usable in this context but using it does not inherently fix the issue this person is having. I suppose you CAN use addressables from asset path but I think most people use AssetReference or AssetReference<T> at which point you're suggesting replacing Resource.Load with something you consider better, but that doesn't address the issue at hand imo

[magic panther]

I think it's easiest by example. I write a line like: PlaySFX(AudioClips.mouseDown [...]). This goes to AudioClips, finds one with mouseDown name, tracks it's according file by path assigned to that name, and plays that sound

[languid spire]

not a problem, next time only code questions belong in a code channel

[unborn urchin]

this isnt code?

[languid spire]

no it's not

[unborn urchin]

oh this is

lol

[magic panther]

Now, I don't want a unity object with all this stuff. Originally I wanted to do this with xml, but yesterday I heard a bunch of weird things about it, so I'm looking for another, safer way.

[floral estuary]

What kind of object do you want?

[unborn urchin]

which would be the correct channel? for some reason i thought this was like a unity beginner channel

[floral estuary]

Do you want to avoid all Unity objects or just MonoBehaviour/Component types

[languid spire]

#💻┃unity-talk but first please check #🔎┃find-a-channel for an appropriate one

[floral estuary]

It sounds like what you want is to make a ScriptableObject and have it reference a bunch of AudioClips. Then anything that needs those clips can just reference the one "database" scriptableobject and grab it from there

[ivory bobcat]

I think he was attempting to load resources by path/directory with an unknown amount of assets to be determined during runtime. Addressables would probably still require some work on their end but be significantly faster than say streamables (what he's probably wanting).

[magic panther]

No, look, I need some kind of file that stores a path and codename for each audio file. That way I can use a AudioManager.GetClip(codename) function or something like that which grabs the file, finds a matching codename, Resource.Loads the file from the path, and if it exists, returns it, otherwise throwing an error.
"some kind of file" being my problem

[floral estuary]

I feel like he's describing what he wants pretty clearly and memory usage has not been mentioned, this person seems to me to have a current goal of finding a more comfortable way to reference the objects, not to make sure they efficiently can have thousands of audio clips

[swift crag]

Correct.

[floral estuary]

If that's the case you basically just want a ScriptableObject or Singleton with a serializable dictionary<string, string>

[magic panther]

I think I look like an idiot right now, I'm just really lost, I'm not sure if this is the right way to go about it, because learning from my 6 months of game development, usually with any newly learned feature comes some evil backstabbing twist

[floral estuary]

You don't look like an idiot, I'm speaking a bit advanced cause I'm having trouble gauging your development level don't worry about it! Okay here's my suggestion give me a second to type

[magic panther]

np, brb 3 mins

[floral estuary]

so first we have these things called ScriptableObject. It's a class you can inherit from like MonoBehaviour but it basically just holds data. But it holds it in a way you can have that data sit as an asset in your project files.

So before we dig deeper, you're wanting to set up a string-string relationship. You want to give it a string for some codename of a file you want, and you want to get back a string telling you its full path. There's a few ways to make that dictionary, since Unity inexplicably is incapable of serializing one of the most important collection types in 2024 :p

[swift crag]

My suggestion would not involve path names at all.

Consider the following

[stark rune]

i want it to open only hen the plaeyr looks at dylan but now it just only works whenm i look anywhere from any distance
https://hastebin.skyra.pw/upusewoheq.pgsql

[floral estuary]

Mine wouldn't either, but as a newcomer to anything I find it frustrating when I wanted to work on something and people just kept telling me not too XD so I'm gonna lay out how to do this but I suggest you listen to Fen @magic panther I think they seem to be on the same thought wave as me

[swift crag]

[CreateAssetMenu]
public class AudioSet : ScriptableObject {
  [SerializeField] private List<AudioClip> clips;

  public AudioClip GetClip() {
    int index = Random.Range(0, clips.Length);
    return clips[index];
  }
}

[cosmic cargo]

hey every1 i have done some basic projects in unity, Now i want to learn how to create opponents with different moveset and how they use them for a combat (GoW kinda) can sm1 recommend me some resources for the same

[swift crag]

This defines a new kind of asset.

You can create it in the Project window, put audio clips into it, and then, crucially....

public class Whatever : MonoBehaviour {
  [SerializeField] private AudioSet clickSounds;
  [SerializeField] private AudioSource source;

  public void ClickHappened() {
    AudioClip clip = clickSounds.GetClip();
    source.PlayOneShot(clip);
  }
}

No strings!

[floral estuary]

mmmmm I don't like this, they're supposed to reference all audio in their game by an index number? That's not very readable

[swift crag]

You just assign a reference to an AudioSet asset in the inspector (along with an AudioSource component in the sc ene)

[floral estuary]

and if one thing gets switched you could likely just never notice

[swift crag]

What index number?

[magic panther]

I'm back, is there a lot to take in?

[swift crag]

GetClip just picks a random clip from a list

[floral estuary]

hang on there's some debate on the best way to do this haha just a sec

right but obviously that's not what they're trying to do

[swift crag]

I don't see why you can't just reference an AudioClip if all you need is a single piece of audio.

it will be simpler and much more reliable than typing in a name and hoping you never get it wrong

[floral estuary]

aw don't scathe the guy for wanting centralized audio management it's somewhat understandable. Though probably less helpful in the long run than one would think, but let the dude work on his project haha

[swift crag]

The point of Resources.Load is that you can find assets without having to store a reference.

If you can store a reference, just do that.

[wintry quarry]

Not only that, Resources.Load doesn't even have any memory advantages. It loads the things up front.

[swift crag]

Loading things by name should be a last resort, not your first choice.

[floral estuary]

It has a little bit, from my understanding prefabs are like serialized versions of prefabs when they're not loaded loaded, though that still takes up memory

ANYWHO

[swift crag]

Names are icky. You can spell them wrong and the compiler won't notice.

[wintry quarry]

Anything in a Resources folder gets loaded at the start of the game. loaded loaded.

[ivory bobcat]

The centralized Singleton manager isn't the issue. It's the identification using strings that's error prone.

[swift crag]

You can move the asset around and forget to update the name.

[swift crag]

Precisely. I have some singletons that provide audio clips in my game!

[magic panther]

hold up yall couldve just told me this is a bad way to go about it

[floral estuary]

If you have a database referencing assets by name that's not super error prone

[swift crag]

yeah, it's called the unity asset database --

😉

[ivory bobcat]

Fen beat me to the punch line

[floral estuary]

mmmmmmmk

[elfin knot]

If you wanna load by string and not have to have the clip loaded in memory at load you could use addressables 😅

[floral estuary]

quite the scathing thing to say, the practical use of that "burn" may vary

[swift crag]

well now I've got to test this..

[ivory bobcat]

We've gone a complete circle now

[rich adder]

lmao

[magic panther]

My whole idea is to mask Resource.Load<AudioClip>("path") under something more managable (using resource.load would require me to jump around my code changing the path whenever I move a file elsewhere. I'd prefer changing the path once in some central thingy)

[floral estuary]

You don't need a path if you have an AudioClip reference

[swift crag]

If you need something more complex than a single audio clip, then you can start defining your own asset types, as shown here

[floral estuary]

public AudioClip myClip;
public AudioSource source;

public void Awake() {
  source.PlayOneShot(myClip);
}```

[swift crag]

I have very few string keys in my code

[wintry quarry]

But why not just directly reference the clip and then it's already resilient to path changes

[swift crag]

Most of them are default values for LocalizedStrings so that they start out with the right table

[magic panther]

Then what's the best way to do this without the need for stuff like on this ss

[rich adder]

jesus..

[swift crag]

Start making lists!

[naive pawn]

arrays/lists

[floral estuary]

public List<AudioClip> playerLandingAudios

[swift crag]

If you ever find yourself writing this:

int foo1;
int foo2;
int foo3;

...then you need a list

[naive pawn]

anytime you have symmetric variables, you want a list

[floral estuary]

public List<AudioClip> playerShootAudios

[magic panther]

But won't that mean I need to find them by [n]?

[swift crag]

So what?

Pick a random one

Presumably you're already doing that, in a much more painful and roundabout manner

[elfin knot]

Dictionary<string, AudioClip> Clips;

[swift crag]

Hence this suggestion.

[wintry quarry]

Honestly how is this any different from using strings though?

[floral estuary]

but also, your database that's storing them by string would have to reference them all the same way

[floral estuary]

unity can't serialize that to inspector

[magic panther]

I have one script that tracks the cursor so far

[naive pawn]

and that n can be a variable. the n inside the name can't

unless you're using reflection, which is really not the right tool for this

[swift crag]

this is non-relevant

[swift crag]

where's my crucifix

[elfin knot]

Need Odin 🫣 😭

[swift crag]

Just serialize a List<AudioClip> for each kind of sound. You can do even do that if there's only one audio clip -- a list of one element is fine.

[floral estuary]

Or CustomInspector or a number of other tools, but I haven't been able to explain Serialized Dictionaries without the dreaded "you're going about this all wrong just don't do what you're doing at all" which obviously is a great learning experience XD

[ivory bobcat]

There are free and paid third party assets for serializing dictionaries if needed but they ought to just move away from strings overall.

[rich adder]

I mean you don't need it they have SerializableDictionary you can do. But no need here

[floral estuary]

unfortunately it tends to happen in a room crowded with talented devs

[naive pawn]

this goes back to strings being potentially error prone
and also you can't store variants easily with this, you'd have to append numbers which is even more problematic

[magic panther]

Alright, so a list of audioClips. Is making a SO that I can access via AudioClips.name straightforward?

[swift crag]

Stop thinking about names.

No more names!

[naive pawn]

for safety in that format you'd need a dict of enums to lists of clips, which is.. quite unnecessary, but i mean, if you want it, i guess

[swift crag]

You have a List<AudioClip>. You don't care what those clips are called or how they got put in the list

Pick a clip from the list and play it. That is it.

The clips could be named "FLORP" or "Dont Play This Oh My God" or "3"

You simply do not care

[magic panther]

How do I pick it. [n]?

[swift crag]

Pick a random number.

[swift crag]

See here.

[floral estuary]

this part

he shows you how to pull a random clip from a given list

[swift crag]

Write your code so that it simply does not matter how many clips there are

[floral estuary]

random number from 0 to the max index in the list

[ivory bobcat]

The audio assets can be directly referenced as the audio assets are known before runtime. Using a reference from the manager would allow them to prevent needing to rewrite code if the sources change. They'll still need to modify references though as those can break

[magic panther]

The amount of discussion disorientates me rn, what exactly do I do with this?

New C# file, paste this in?

[swift crag]

Do you not understand what GetClip does?

I am simply explaining how to pick a clip from a list of clips.

[elfin knot]

Yes but I think he wants to be able to play the clips programatically without having to explicitly choose the clip.

private Dictionary<AudioType, AudioRetriver> _audioClips;

public void Play(AudioType type) {
  _audioClips[type].PlayRandomClip();
}

So how can he define the data without some identifier for the type (string, enum, type value, etc)

[floral estuary]

Yeah this is kinda going 8 different directions. This has turned into a discussion on best practices which I don't think is necessarily the most helpful thing for you at the moment.

[swift crag]

too many cooks, yes

[ivory bobcat]

That's a scriptable object. Use it to create a scriptable object instance and populate it with your audio assets.

[swift crag]

let's do a thread. i will explain the simplest option.

[magic panther]

This might be a lot to ask, but a step by step in one message would probably be the best to clear this up

yeah

[naive pawn]

for now, read it and understand it
GetClip has the core logic of what you should do

[swift crag]

picking random clips

[floral estuary]

there's the self-appointed alpha in the room "let's make a thread and I'll be the one do it" XD okay I'll leave you to it

[ivory bobcat]

They're reducing clutter, it's a perfectly valid response

[swift crag]

Executive decision 😄

[floral estuary]

My point is when a beginner asks a question, it's a good time to answer their question. Telling them they shouldn't be doing the thing the way they're doing it at all immediately feels bad for learning to me. I would rather answer the question they asked, then suggest that "hey that's probably not the best way though".

Like you might think abstract scrob events are the best way to organize a project, but if someone is just trying to spawn their enemy I don't think we should be talking about that :p you can answer the question then lightly suggest a different approach than the one they now understand

[naive pawn]

until the beginner takes the answer and just leaves without waiting for the extra cleanup 🫠

[floral estuary]

If they wanna be a shitty coder I think that's on them. Having 10 people yelling across each other arguing about what they should have done instead of the thing they're trying to learn... aint it

[naive pawn]

this even happens when the cleanup is in the same message, rarely, but it does happen

[floral estuary]

I don't think that has to do with what I'm saying, yes internet people can be lazy but I don't see how that pertains

I don't think you're ever gonna push a copy-paster into being a real coder by way of teaching them best practices

[naive pawn]

they do come back and necessitate cleanup afterwards when it's been expanded on

[floral estuary]

in that situation that person has chosen their path :p

[naive pawn]

so in my experience, telling them that it's a bad path upfront tends to be more productive long-term

[ivory bobcat]

Imo, it doesn't matter how it's presented. The matter of importance is with enabling the individual to complete their task in the simplest yet correct way. I try hard not to support ill use tools or practices that'll have others needing to fix said bandaids in future tasks.

[naive pawn]

im not against actually answering their question, but sometimes that's not the most important part of actually telling them what they need to know, xyproblem and everything

[floral estuary]

Trying to teach a new coder to avoid all technical debt forever is a losing battle

[magic panther]

That's what I prefer

[ivory bobcat]

I'd tell them if the task is too great for them or shoot myself in the foot and attempt to hand hold them through it.

[naive pawn]

but excess technical debt is a something worth fighting for imo, especially when it's a core concept

literally something being done for them

if they don't know about it, it's gonna be a lot more painful than it should

[magic panther]

But in a "Not how it's usually preferred to be done" rather than a "It's objectively a horrible way to do it" (unless it actually is)

[naive pawn]

that pain without knowing there's an out seems to be more draining/burnout inducing

[floral estuary]

I mean clearly everyone is against my side of this debate here, but I've been a coder trying to learn something, came up with a small learning project, and been told "don't do any of that here's this simple thing or 3rd party thing that does it all for you cause why are you doing that" at which point I do nothing because the whole learning experience I designed is apparently just a button click, when there were still valuable and relevant things I could have learned from that experience

I just think the best response to a beginner asking a question is usually to first answer the question

[swift crag]

you do not know what you do not know

"unknown unknowns", perhaps

[naive pawn]

of course there are valuable things to learn in every path, good or bad
but you have to weigh:

• how valuable is it to their overall learning, as a beginner?
• how valuable is it to their immediate task?
• how valuable is it to their long-term task? (ie, the game)
• how much time/focus is it going to take away from the stuff more relevant to the above 3?
  stuff about performance or optimization tends to not be ideal for beginners just learning how to do stuff
  sometimes you don't need to learn it; sometimes you can't learn it yet without the necessary experience to understand it

[floral estuary]

But you also have to consider how likely this person is to learn about serialized dictionaries in a later scenario. Not SUPER likely I'd bet. Will serialized dictionaries be helpful? almost certainly. How likely are they to hear that they shouldn't reference things by string? It's certain. Look how the room swarmed around it.

This person could have learned how to string,string reference things, one of the most lacking/broken oft-needed features in Unity, as well as that they don't need to use strings for AudioClips.

Instead, they just learned the more obvious thing because people solved their problem instead of answering their question. I'm not saying it's not important to learn or note not to reference things by string, but that other information would have also been invaluable, and I feel like I was like "okay hang on let me type a full explanation", and everyone was like "no I can type a quick explanation of a whole different approach much faster than you can do that" :p which is frustrating tbh

[naive pawn]

ok im confused, dicts were only recently mentioned, weren't they?

[floral estuary]

One might think, I haven't been able to say much of a word about them XD

but no I mentioned them early on

[naive pawn]

ah, i mustve missed that while backreading

[floral estuary]

all good, again it devolved into a discussion on best practices which is part of the frustration

[naive pawn]

i mean, that's quite a natural progression from several variables, so i dont' see how that's not super likely

[floral estuary]

I feel like the core of what I'm saying is being glazed over

[swift crag]

Oftentimes, the original question is not the correct one.

[naive pawn]

i think the divide here (i mean, between your stance and the rest of us) is kinda over a subtle difference: useful overall vs useful now
i don't think any of us think string references aren't important or anything, but it's less important to their development as a beginner, since direct references are more typically used
i don't think any of us would object to an explanation of string references, but more about presenting that explanation as an answer to the problem (vs an answer to the question)

[swift crag]

Finding that "true question" is challenging.

And I think doing so is a vitally important part of pedagogy

(ooh, five dollar word)

[naive pawn]

if they don't know normal references, and are then taught string references, then, well they'd probably just keep using string references
that's gonna be a pain both for them and future helpers

but of course, quick discussion throws all that nuance out

[floral estuary]

If a person asks a question and we tell them best practices instead, they didn't learn the thing they wanted. If a person asks a question and we tell them best practices, and then someone else says no that's not the best way, and then we all argue for an hour, they learned nothing and they probably leave.

I've left modding communities as a whole (cough minecraft) because I wanted a specific piece of information and I could NEVER get that information I wanted to learn without "WELL WHAT ARE YOU TRYING TO DO" with 800 different opinions on how I should go about it instead of learning what I wanted to learn. It's honestly infuriating sometimes. Beginners are often not trying to accomplish something, they're usually just trying to learn.

[wispy coral]

dose anyone know where to report problems with the unity learn courses?

[ivory bobcat]

From what I've seen, there were two underlying concerns. The first being a means to prevent needing to rewrite code in the case that sources are modified (placed elsewhere). The second is with the means of accessing the data. The first is a given that the individual should use a manager to remove management responsibility from individual scripts. The second was where folks would suggest using an alternative to strings (the actual clips themselves to prevent errors) - they would be working with some other identifier instead (indices with fens suggestion).

[floral estuary]

I understand that #💻┃code-beginner message still talking around my point though

[swift crag]

we disagree with your point

[naive pawn]

they didn't learn the thing they wanted.
the thing they wanted is most often, what they want to do, not what they literally asked
it's a chronic problem, such so there's a name for it: https://xyproblem.info
it's just... a common beginner issue, unfortunately

[floral estuary]

you might, most people are ignoring it because it's harder to debate than best practices

[naive pawn]

im not sure what the core point is
if it's this

If a person asks a question and we tell them best practices instead, they didn't learn the thing they wanted.
i do disagree, yeah
especially in the context of beginners, where "asking the right question" is not a developed skill yet

[rich adder]

most likely somewhere on the website / course

[wispy coral]

ill search around, thx

[floral estuary]

I mean what's the line on this

there's always easier ways to go about things

obviously the line is somewhere before "use unreal engine, it has that built in"

but where do we land on suggesting a beginner who's trying to learn to code just use a third party asset?

[naive pawn]

industry standard, probably

[floral estuary]

kind of an ambiguous term, though, seems like it would lead to a room of people yelling over each other about the best way to go about things

[naive pawn]

if they know enough to not want that and learn what that does for themselves, then kinda sounds like they're not a beginner anymore

[floral estuary]

I guess a main thing is if you answer their question, we're all answering the same question. If you try to answer their intent, we're all answering what we think their intent is and it's loud.

[swift crag]

If we only ever answered the original question, without doing any digging, we'd be doing a disservice.

[naive pawn]

if they're a beginner and they want to learn to code, in general, and there's a widely-used third-party asset that makes life easier, well, they have bigger fish to fry than remaking that asset

IDEs and LSPs are third-party assets

[swift crag]

We'd be reduced to an autocomplete engine.

I disagree very strongly, on a philosophical basis, with this idea

[ivory bobcat]

Either be responsible and create a thread to attempt writing-for-them-code or guiding them through the process (hand in hand). Or provide information as correctly as possible, knowing that they'll struggle but hopefully pickup better practices.

[naive pawn]

writing-for-them-code
uh, spoonfeeding?

we have a word for that, and it's discouraged

[ivory bobcat]

Practically. We're human and feel the need to assist a bit more than normal every once in a while.

[naive pawn]

that just deprives them of the oppurtunity to learn

[floral estuary]

I feel like that's because it's being thought of as binary, though. You can still inquire about best practices.

"Hey how do I make a serialized dictionary for this?"

1. "Here's how, but that's probably not what you want to do. Here's a better way."
2. "Don't do that at all. Do it this way."

option 1 sounds better to me

[swift crag]

These are identical responses.

[floral estuary]

they are absolutely not

[swift crag]

the first one is just wrapped in bubble wrap

along with an unnecessary detour to something that's a bad idea

[floral estuary]

those are logically and socially completely different

okay dude I'm done

[ivory bobcat]

Guiding was part of the first alternative 😅

[naive pawn]

i'd prefer "That's probably not what you want to do. Here's a better way. Here's how if you're interested"

[swift crag]

I misread the first option. I see.

I would not immediately provide an implementation I consider to be a bad idea.

[floral estuary]

I would be totally fine with that, I just don't feel like that's how this went down

[naive pawn]

i mean i wasn't here for the initial convo so i can't comment on that

[wispy coral]

I have 0 prior experience on how to code and if someone offers me the better way of how to make, i dont know, a fps player controller script i will go for the better way of doing it

[frosty hound]

How can someone offer a better way if they haven't seen your original way?

[warm maple]

So I'm not really sure if these types of questions can be answered here, or are the right place to ask, but I wonder how certain functions like sin/cos/tan work in a gamedev perspective? For example if I wish to create a circle that keeps repeating itself, with how do we keep the particle going? Do we typically use a while loop for that to make it infinite?

[swift crag]

When you attach a component to a game object, Unity runs its Update method every frame.

So, each time the method gets called, you're one frame ahead from last time

Time.time has gone up by a little. Other objects have moved around.

[floral estuary]

Depends on where, a shader would likely use sin(Time.time) and just work with it as it mathematically is

[wintry quarry]

how certain functions like sin/cos/tan work in a gamedev perspective

They work the same way they work everywhere else in the world. Sine is: angles in, a value between -1 and 1 out

For example if I wish to create a circle that keeps repeating itself, with how do we keep the particle going
THis is really a question about "how does the game loop work, when does my code execute" etc, than any thing to do with math functions

but "circle that keeps repeating itself" is pretty vague

[floral estuary]

To be honest most people in Unity wouldn't use sin though. They'd probably have the thing rotate in Update() and just have it always moving in its forward direction.

[warm maple]

Seems like I shouldve made it more clear. I took an example I saw from Minecraft to kind of showcase with what I meant with that the circle keeps going without stopping.

[wintry quarry]

Yes you could use sin/cos for this

just updating the object's position in Update, based on the result of sin/cos(time)

also there are multiple functions at play here

[floral estuary]

I didn't think it was vague. We have an Update() method in unity that is always going off, so we don't necessarily need a loop

[wintry quarry]

one determining the height of the object, and one determining its position on the x/z horizontal plane

Anyway yeah this is really just a "how does Update work" question

the trigonometry is a red herring

[swift crag]

Right. There are quite a few ways to get that movement.

[wintry quarry]

I would describe this as "an object moving in a circular path"

[warm maple]

I'm mainly trying to break it down into pseudocode, to know what's actually going on, but as I understand, we would need to update its position, in the Update method, and the position also differ as we would need to calculate that each time?

[swift crag]

Indeed.

I'd go with what Chloe suggested. I actually do very little trig in my code...

Unity provides many useful methods for performing movement and rotation

[wintry quarry]

void Update() {
  var offsetPosition = new Vector3(Mathf.Sin(Time.time), 0, Mathf.Cos(Time.time));
  transform.position = centerPosition + offsetPosition;
}```
Something this basic will get you most of the way there

[warm maple]

Kind of how we could make a function f(x), and for each x, it would have a different position

[gilded canyon]

has hatebin closed?

[swift crag]

Exactly!

[wintry quarry]

(this doesn't handle the up and down, just the circle)

[swift crag]

If you can explicitly calculate the position based on the time, then it'll be great

[naive pawn]

well first decide how you want to make it move
you could make it modify the existing position, or directly set its current position
the former would be just rotating and then stepping forward
the latter would be using trig

[swift crag]

This makes sure you don't get little errors that build up over time

Closed-form functions are great

[warm maple]

Thanks! This will certainly help me into better understanding the process of how systems like these are broken down :)

[rich adder]

seems like its gone

[gilded canyon]

https://paste.ofcode.org/utfXwZJChAjcYJ873DUfaG can anyone explain why my code is giving a object not set to refernce error as i have put and else incase the ray hits nothing?

[rich adder]

hit probably contains null

[gilded canyon]

ive set a condition if hit is null

with else

[ivory bobcat]

Possibly some others as well https://discord.com/channels/489222168727519232/1300047504003432490

[rich adder]

your if statement is attempting to access properties in the Hit even if hit was null

[gilded canyon]

i see lemem try smth

yup fixed

i just didnt clock in that it would try to access somethin that doesnt exist

[rich adder]

consider using early return pattern

if(hit == null) { multi = 1; return;} 
//check rest, n set multi to whatever

[gilded canyon]

will do

[thin birch]

Hi, how can I use a TMP object in the game world and not in the UI?

[naive pawn]

put it in a canvas that's set to world space

[slender nymph]

or use the TextMeshPro object that is explicitly in world space already

[verbal dome]

PIck GameObject > 3D Object > Text Mesh Pro from the menu

[thin birch]

how would I do that?

[slender nymph]

#💻┃code-beginner message

[thin birch]

ah ok, is there a 2d version or does it work fine?

[verbal dome]

I'd guess it works fine in 2D, try it

[slender nymph]

i imagine it probably doesn't play perfectly with the 2d sorting, but that's the only thing that wouldn't work about it in 2d considering 2d is still 3d. the only major difference between 2d and 3d are the physics engines used

[thin birch]

gotcha ty

[gleaming plaza]

idk what I'm doing wrong

[slender nymph]

seems like you may have your own class called GameObject for some reason

[ivory bobcat]

UnityEngine.GameObject laser;
but preferably don't use the name GameObject

[gleaming plaza]

what?...how?

[slender nymph]

look through your own code and find out?

or better yet, right click the GameObject type in the laser declaration and go to the implementation

[gleaming plaza]

that was more ideal

[ivory bobcat]

Unless VSC is just misconfigured and throwing improper suggestions. I'd check the console errors from the Unity Editor

[polar acorn]

At some point, you made a script and named it GameObject

Don't make scripts with the same name as unity classes

[gleaming plaza]

one of my scripts had a class called GameObject idk why the heck it was called that

[ivory bobcat]

Did you call it that?

[gleaming plaza]

the script is called Laser, idk why the the class wasn't called that

[thin birch]

yea renaming a script keeps the class name as it was before

[rich adder]

Yeah renaming the file won't affect class

[gleaming plaza]

I don't remember ever creating a script called that, but I probably did by accident

[burnt vapor]

Unity automatically renames the files because if it did not, renaming would break the script since Unity requires both to match

[slender nymph]

unity doesn't automatically rename the class, and it's up to the IDE's refactor tools to rename the file when renaming a type. also as of 2022.2 the file name and class name are not required to match

[dark cape]

Does anyone know how to get rid of the grayed out code suggestions in visual studio?

[naive pawn]

it's copilot, try searching settings or extensions or google for it

[steep rose]

I thought that was intellicode

[slender nymph]

that's intellicode, not copilot

[dark cape]

I think I found the option

[wispy coral]

was gonna ask the same thing

[dark cape]

but I also thought that 3 other times

I think this gets rid of it

[naive pawn]

wait do they just look the same or am i blind

[slender nymph]

dunno, i don't use copilot. but that is 100% the default behavior of intellisense

[steep rose]

co pilot is like gpt and just gives you code I believe (just a guess), intellicode just guesses what you want

[wispy coral]

if i disable intellicode it will just not give me more suggestions for code?

[slender nymph]

you'll still have intellisense which is separate

[zenith cypress]

intellicode is the in-line LLM suggestions. intellisense is your autocompletion stuff.

[wispy coral]

alrighty

[oak cloak]

every time i bake my Lighting it crash

[slender nymph]

stop crossposting. this is not a code question.

[oak cloak]

my bad

[mighty compass]

anyone using c++ here in unity? how do you do it

[naive pawn]

uhhh why do you want to do that

[mighty compass]

lower level language, has its advantages

[slender nymph]

you don't. you can use c++ to write a native plugin, but your typical unity scripts will be in c#

[mighty compass]

kk

[ivory bobcat]

What specifically are you targeting from c++?

[mighty compass]

networking

client/server interactions

[ivory bobcat]

Doesn't seem exclusive to c++. If you've already got ready made binaries, you could probably import the dll.

[mighty compass]

kk

[grand snow]

ofc you need to compile for each platform you desire (though android/ios can be compiled for you by unity if the src files are included, not sure about others)

[covert flower]

not 100 percent sure if this is classed as beginner but i followed the documentation i was using to the letter and idk how to fix the error

[frosty hound]

Why do you have = at the end there?

[ivory bobcat]

A value cannot be assigned another value. The thing on the left side of the assignment operator needs to be a variable to be assigned the value on the right side of the assignment operator.

name = "Bob";//valid
"Bob" = "Steve";//invalid
GetName() = "Jones";//invalid```

[grand snow]

you meant to use == to compare right? You may need to put brackets around the 2 Mathf.Abs().

[covert flower]

ty guys the video stupid mistake lmao

[mighty compass]

how can I check if a Ray intercepts with an object?

nvm i found the RayCast class

[cosmic charm]

I don't know why but sometimes the character stops moving even when i'm pressing the move button, any ideas?

[paper sable]

hey guys, im watching a video about handling slope movement, i've followed all of the steps but my character automatically jumps off the slope when i enter it for some reason, i dont think i've done anything wrong, so i dont really know why this is happening. does anyone know why this may happen? this is the code that handles slope movement:

    private void HandleMovement()
    {
        moveDirection = orientation.forward * moveInput.y + orientation.right * moveInput.x;

        if (OnSlope())
        {
            rb.AddForce(GetSlopeMoveDirection() * moveSpeed * 20f, ForceMode.Force);
            print(GetSlopeMoveDirection());
        }

        if (grounded) rb.AddForce(moveDirection.normalized * moveSpeed * 10f, ForceMode.Force);
        else rb.AddForce(moveDirection.normalized * moveSpeed * 10f * airMultiplier, ForceMode.Force);
    }

    private bool OnSlope()
    {
        if (Physics.Raycast(transform.position, Vector3.down, out slopeHit, playerObject.localScale.y + 0.3f))
        {
            float angle = Vector3.Angle(Vector3.up, slopeHit.normal);
            return angle < maxSlopeAngle && angle != 0;
        }
        return false;
    }

    private Vector3 GetSlopeMoveDirection()
    {
        return Vector3.ProjectOnPlane(moveDirection, slopeHit.normal).normalized;
    }

[cosmic charm]

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

public class CentaurMoveState : CentaurGroundedState
{
    public CentaurMoveState(Centaur _centaur, CentaurStateMachine _stateMachine, string _animBoolName) : base(_centaur, _stateMachine, _animBoolName)
  {
  }

    public override void Enter()
    {
        base.Enter();
    }

    public override void Update()
    {
        base.Update();

        centaur.SetVelocity(centaur.moveSpeed * xInput, centaur.rb.velocity.y);

        if (xInput == 0 || centaur.IsWallDetected())
            stateMachine.ChangeState(centaur.idleState);
    }

    public override void Exit()
    {
        base.Exit();
    }
}

this is my move state, some how the xInput is getting updated to 0, and idk how

or the mvoeSpeed

[kindred cedar]

am i able to ask for help on a script in here>

[green flame]

Hello! I don't know what I have forget in my code someone can help me ?

I have this script:

And I created a scriptable object in the assets folder like this:

But when I log it in like this in my first script:

I log "Null" 😦

[ivory bobcat]

Show the inspector for the game manager object in the scene.

It should have a game manager component with a game data field.

[green flame]

Yes

Here is

[ivory bobcat]

So it's None right now aka null

Make it not None or rather, where do you assign it a value?

[green flame]

Gamedatas should have default value instead of this :

[ivory bobcat]

It's a reference type so it should not have a default value.

Use your scriptable object to create a scriptable object instance.

You should be able to create a last game data scriptable instance asset

It would be under the menu Scriptable Objects as you've set

After you create that instance, reference that instance by dragging and dropping it into the field that has None.

These SO instances would be like component objects but not in the scene and without needing an object to be attached to - unlike regular components.

Basically asset components

I've got to run, good luck.

[green flame]

Ty i'll look at this !

[ivory bobcat]

Random youtube video that had the creation of a scriptable object instance https://youtu.be/0IrWYG4JdHo?t=104
Yours would be at the path you specified - at the top of the list normally in your "Scriptable Objects, ..." submenu and would be named "LastGameDatas".

[green flame]

It's done thank you! My scriptable object is working well 😄

The workflow is not very user friendly but now I know :3

[ivory bobcat]

Think of the original SO script that you've typed as a template for creating many instances as assets. The SO script is an asset as well but just the template for creating many others. Useful in the case that you've got a lot of objects in the scene that need their own unique SO instance.

[tight latch]

so Im making a 2d game as practice and i don't know how to make my line i draw collide with my player so it doesnt just fall through(I don't really know which collider to use i think)

[green flame]

Yeap I understand ty 🙂

[stable quail]

Here's the docs on 2D colliders https://docs.unity3d.com/6000.0/Documentation/Manual/2d-physics/collider/collider-2d-landing.html

[brisk oasis]

After a lot of hard work, I finally figured it out. Thank you for your advice!

It is for my third game only but I like to challenge myself

[proper needle]

how do i call an objects own tag in unity?

if i wanted to put the same script on a bunch of different objects

[sterile radish]

hi, im making a doodle jump clone with different platform types with different behaviours. i want to make seperate scripts for each type of platform but i dont want to copy a big collision code chunk thats the same for every platform into each platform script. is there a more efficient way to do this?

[steep rose]

I'm glad to hear that! It is good to challenge yourself but keep in mind to not get burned out or do something overly zealous

[brisk oasis]

Of course

[proper needle]

how do i call an objects own tag in unity?
if i wanted to put the same script on a bunch of different objects

[north kiln]

what does call mean

[tulip nimbus]

 public GameObject prefab;
 public Vector3 origin;

 private void OnTriggerEnter(Collider other)
 {
     for (int i = 0; i < 10; i++)
     {
         StartCoroutine(wait1());
     }

     Debug.Log("Triggered!");
     

 }

 IEnumerator wait1() 
 {
     yield return new WaitForSeconds(1f);
     Instantiate(prefab, origin, Quaternion.identity);
     

 }

What can be done here? I want to instantiate a prefab 10 times every second. However this seems to fire all at the same time

[north kiln]

you're running 10 identical coroutines at the exact same time

Either add the loop inside the coroutine, or pass a different delay/wait into the coroutines you start.

[polar acorn]

Instead of starting 10 coroutines that wait 1 second then spawn, start one coroutine that waits a second then spawns 10 things

[tulip nimbus]

unfortunately i want to spawn objects that have a collider, so spawning them at the same time would shoot them out in all directions

[polar acorn]

That seems to contradict what you said you wanted

[tulip nimbus]

this is just to test scripting since id like to make a gun that shoots a salve later on that only needs one button press, but shoots rounds delayed

[polar acorn]

You said you wanted to spawn something 10 times, every second

[tulip nimbus]

my bad!

very poor wording but i meant spawn a prefab once, 10 times, every second

[signal mango]

So you want ten spawns, spread out over a second

Not ten spawned immediately each second

[tulip nimbus]

yup! each spawn with a duration of 1s

[signal mango]

That seems to be what your code above does, it will create ten "spawner" coroutines that each wait one second before spawning

They will of course end up spawning at the same time since they all started at the same time, and all wait one second

Do you want some kind of randomness added to the timer or something?

[teal viper]

Instead of waiting 1 sec in each coroutine, increment the waiting time by 1 and pass it to the coroutine for it to wait. Not ideal but at least that would work.

[tulip nimbus]

i oversaw this, this worked. Thanks yall

[signal mango]

Oh I think I get what you wanted now, you want ten spawns where each one waits one second after the previous spawn

[tulip nimbus]

ya you were all kind of right, i just had to put it in the for loop

[signal mango]

In that case yes, putting the loop into the coroutine itself would work:

private void OnTriggerEnter(Collider other)
{
    StartCoroutine(DelaySpawn(10, 1));
}

private IEnumerator DelaySpawn(int count, float delay)
{
    for (int i = 0; i < count; i++)
    {
        yield return new WaitForSeconds(delay);
        Instantiate(prefab, origin, Quaternion.identity);
    }
}

[sterile radish]

why doesn't my cracking platform detect that the player is colliding with it? my player has a box collider 2d and a rigidbody 2d. and my cracking platform has an edge collider with a platform effector. the edge collider is set to trigger.

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

[verbal dome]

How do you move the player?

[sterile radish]

hi, i've fixed this now, but thank you regardless!

[stuck rampart]

Was working fine just a few mintutes ago, not sure what I touched: "UnassignedReferenceException: The variable combineParents of MeshCombiner has not been assigned. You probably need to assign the combineParents variable of the MeshCombiner script in the inspector." Please help im new to unity and not good at programming in general. im using the kart microgame scripts if that helps

i tried to make a pit-limiter kinda thing in my racing game but it didnt work so i deleted it and now this, it was seperate so i dont know what happened

[slender nymph]

You probably need to assign the combineParents variable of the MeshCombiner script in the inspector

[wispy coral]

how do i reference a variable that's in my script but i changed its value in another script

[stuck rampart]

i cant find the gameobject with the script attached

[slender nymph]

search your scene using t:MeshCombiner as the search term

[stuck rampart]

ill try it right now

@slender nymph i found it, but where do i assign combineParents now?

sorry if this is a really dumb question 🙏

[verbal dome]

Is combineParents a list or array?

How could it be null 🤔 Unity should initialize serialized lists/arrays automatically

(Not a question to you YaoMing, just wondering)

[stuck rampart]

ok

[verbal dome]

Clear your console and enter playmode again

See if the error still shows up

[stuck rampart]

yeah it still does

[verbal dome]

Open this and show what is inside

[slender nymph]

and make sure you're doing the search at runtime when the error actually appears

[stuck rampart]

its 6 and has 6 emptys

[verbal dome]

Oh and check for instances of meshcombiner in playmode

[stuck rampart]

wait

[stuck rampart]

the error starts after i press the play button...?

[slender nymph]

i am aware. but you searched the scene after you left play mode

[verbal dome]

You can hit pause and then search

[stuck rampart]

it did the error pause thing

automatically

[verbal dome]

You can toggle that off in the console

But thats fine

[stuck rampart]

what would happen if i set the value to 0 and didnt use it?

is that even possible 💀

im not sure what i had combined

[verbal dome]

We dont know what the meshcombiner component does but sure

Currently it has 6 empty elements anyway

[stuck rampart]

whatever religion u believe in pls pray real quick 🙂

wow it worked

will this cause any problems later on? this part of the game is from the unity kart thing so idk

[mighty compass]

Ive got this basic class that is assigned to each building object that I place, Im trying to make the doors toggleable (open/close), if im making am ultiplayer game, where should I have the door logic, where should it check if a player has tried to open it

[verbal dome]

No comments on multiplayer, but it is common to have your class implement an interface like IInteractable, which could have a Use method for example

Your character can raycast or do some other physics query to find the object it is aiming at

Then you'd try to get the IInteractable interface with TryGetComponent

If you find it, call Use on it

I'm sure this is a well covered topic if you look online

[teal viper]

Guys i have a question about setting up cam with cinemachine , can i ask it here

[stuck rampart]

i think so? ive been here for 1 hr lol

[round scaffold]

Hi, im making a 3rd person movement where the player moves in the direction of the inputs oriented by the direction the camera is moving, (gta movement for reference),

im trying to make the player move via rb.AddForce (since im used to using that for movment) in the same speed regardless of the direction the camera is facing,
I need help with the math that applies the speed in the correct direction, the current bug is
when i look in certain directions the speed would go up to 200-300, and then be normal in others
https://paste.ofcode.org/xgQGBkSAft7pEV7HghPP2P
the code block is just a function being called in fixedUpdate please help me its been hours :((

im fairly new to 3d sorry if this is something simple lol

heres a video of the bug incase anything is confusing

[verbal dome]

 float currentVelocity = rigidBody.linearVelocity.z;```
You are only using the Z axis here 🤔

Perhaps you want linearVelocity.magnitude?

FYI, linearVelocity is in world space, not relative to the rigidbody

[round scaffold]

i could kiss u , consentually

i had converted the formula to use floats so i can multiply it by the direction

compeltely forgot about it

it works thank u

[magic panther]

How do you guys recommand I do my configuration files? So far I've used XML, but recently heard that's not a good way to go about it

[teal viper]

ScriptableObjects. It's not like XML is bad, it's just less convenient than SOs.

[magic panther]

using UnityEngine;

[CreateAssetMenu(fileName = "GoalConfig", menuName = "Configurations/GoalConfig", order = 1)]
public class GoalConfig : ScriptableObject {
    [Header("Properties")]
    public float movementSpeed;
}

Anything wrong here? For now this is all I need

[teal viper]

Not that I can see. Does it not work?

[magic panther]

It works, I'm just making sure if there's something I should avoid here

[teal viper]

Ideally, I'd make the field private and add a property. Or add an auto property with an attribute.

[magic panther]

using UnityEngine;

[CreateAssetMenu(fileName = "GoalConfig", menuName = "Configurations/GoalConfig", order = 1)]
public class GoalConfig : ScriptableObject {
    [SerializeField, Tooltip("How fast the goal follows after the cursor")]
    private float movementSpeed;

    public float MovementSpeed {
        get => movementSpeed;
        set => movementSpeed = value;
    }
}

Like this?

[teal viper]

Yeah. Is it supposed to be modifiable from outside this class?

If not, then delete the setter.

[magic panther]

Yeah, just delete the set => movementSpeed = value line?

[teal viper]

Yes. And then you can make it shorter:

public float MovementSpeed => movementSpeed;

Or even replace the field as well with

[field: SerializeField]
public float MovementSpeed { get; }

[acoustic sequoia]

Hey everyone, quick question. i have two scripts. on eof them derives from another. the base class is to hide all the mess that will be duplicated across many of the same gameobjects..
how do i make each one of them have a unique event tied to it?

here are the scripts first the base and then the unique script..

{
  *** removed all irrelevant code

  public Action<int> debugEvent;

  private void OnEnable()
  {
    debugEvent += OnDebugEvent;
  }
  private void OnDisable()
  {
    debugEvent -= OnDebugEvent;
  }

  public abstract void OnDebugEvent(int value);
}```

unique class
```public class DebugSliderValueEvent : CustomDebugSlider
{
  public override void OnDebugEvent(int value)
  {
    // do something unique
  }

}```

[teal viper]

Just declare another event in the extending class and invoke it in OnDebugEvent

[wintry quarry]

You can use UnityEvent, and there's no need for inheritance

[acoustic sequoia]

is unity event, where i drag and drop into inspector?

[north kiln]

You can't use SerializeField on a property without a setter

Unless there's something I've missed, Unity can't deserialize over readonly fields

[acoustic sequoia]

Also i need to run code for that specific class and unique event... sorry if that was unclear..

[wintry quarry]

Basically with UnityEvent you'd be moving the specific behavior to other scripts

You'd be using composition instead of inheritance, which is usually more flexible and extensible

[acoustic sequoia]

right, but how do i do that and keep the current code that is inherited?

[wintry quarry]

Why do you need inheritance? There's nothing in your code to be inherited

You will still have the CustomDebugSlider component on your GameObject. Inheritance buys you nothing.

[acoustic sequoia]

i need to do this... which i didn't include in my code example above...

inherrited code

  public void DebugEvent(int value)
  {
    sliderValueText.text = value.ToString();
    slider.value = value;
  }```

unique code
```public void UniqueDebugEvent(int value)
  {
    DebugEvent(value)

    // and unique UnityEvent.Invoke();
  }```

or sorry wait.. that's not right

[wintry quarry]

I don't see how inheritance would make this better

Put the unique code on a separate script and assign it in the UnityEvent inspector

The rest stays here

[acoustic sequoia]

i want to do this..

UnityEvent.Invoke(); <--- this includes the inherrited code```

[wintry quarry]

Again, I don't see how inheritance improves that though

[teal viper]

Weird. I was pretty sure I has some properties like that. Maybe it's just my imagination.🤔

[wintry quarry]

You just make a function that does the "common stuff" and then invokes the Unity event

And call it

[burnt vapor]

It allows private set, maybe you'd like that instead

[teal viper]

Hmmm... I guess I did't have such properties without a setter. I do have some with a private setter indeed.

        [field: SerializeField]
        public Inventory Inventory { get; private set; }

[acoustic sequoia]

so hold up, i know i'm not understanding exactly.. but let me tell you exactly what i want to do and then tell me what i should do..

forget all the code above.

1. I have a debugManager that will handle all the unique methods.
2. i have 12 Custom Sliders that will all have a unique function assigned to them using unityEvents in the inspector from the debugManager.
3. all of the sliders, when the unityevent is invoked, i need to run the unique function first and then the inherrited function.

so for all sliders they will have two functions:
1 that is unique amongst all other sliders
and 1 that is shared amongst all other sliders.

[wintry quarry]

I think the event is throwing you off. It doesn't really matter if it's invoking a unity event, or any other code. Just call it normally.

Make a function that invokes the event and then runs the abstract function

[acoustic sequoia]

ok thanks!

[wintry quarry]

But it's unclear what these "inherited" functions are. To me, it probably makes more sense to just add a second Unity event rather than writing 12 subclasses. But it depends what you're actually doing

[teal viper]

Kinda hard to give an advice without knowing the actual context

[acoustic sequoia]

so here is the main goal.

imagine i have a player with a level and a speed.

i want to be able to play the game normaly and upgrade my speed and my level whenever those functions are triggered.

(makes sense)

now for the part i'm trying to figure out.

i want to link in a debuging system that allows me to update the players level and speed through that menu at runtime.
so the debug UI needs to update the game when i want it to, and also the game needs to update the debug menu when it needs to.

so when i'm playing, i have an easier time testing out things.

so basically, i'm trying to create a two-way system that is for testing purposes only. so that i can easily "plug-in" my debug system without added a ton of littered code throughout myproject. when i'm done.. unplug and it works perfectly fine. no ties to anything.

[acoustic sequoia]

so i have 12 sliders that display the current stats of my character at any state in the game. and i the idea is to have the ability to update the debug console to give my player the stats i need for testing.

[burnt vapor]

So your debug manager has the same stats, but rather configurable instead of being read only?

It sounds easier to just make the stats page configurable when debugging

If you intend on the debug manager, instead of making an event for each stat, maybe use INotifyPropertyChanged

[acoustic sequoia]

so yeah that's easy. and that's what i want to do. i'm trying to link that info to a UI system that is for debugging only. by creating prefabs dragging and dropping the prefab into the menu. then drag and drop one function to it and it works. for any stat that i create in the future.

this isn't a "lets do this everytime i create a new project kinda thing. i want to do this once, package it up and be able to drop it into any other project i have and litterally do two drag and drops per stat i want to display.

[teal viper]

I still do t get what the second event is for, or the extra code in the extended class. Can you provide an actual real life example?

[acoustic sequoia]

forget the events. forget my code i showed. just try to imagine what i just explained. sorry for the confusion

[teal viper]

It's hard to imagine it without any actual code, because there are multitude of ways to implement what you described.

[acoustic sequoia]

can you reference a website that talks about this kind of stuff, i'm not sure where to start. i need to learn about it more before implimentation

[teal viper]

The way I'd do it, is either have an editor script or in game ui that bind to a certain character and displays and modifies it's stats.

[teal viper]

I don't have any specific links try googling "character stats debug system". But I really doubt there's gonna be a detailed tutorial for that specifically.

Break the feature down into components and tasks and try to implement it. When you actually have something working, you can ask for actual advice on how to improve or refactor it.

[copper crest]

Its saying the variable is not assigned even though it IS assigned in the inspector

[teal viper]

If it says not assigned, then it's not assigned. At the time the error is thrown. It could also be a different object that throws the error.

[copper crest]

it dosent removes it real time

[teal viper]

Then it's probably a different object. Log the variable and the object that accesses it in code.

[copper crest]

there IS only 1 object of that type

[teal viper]

Not untill you debug it.

[copper crest]

I duplicated it and it worked

and now it dodsent work

it worked then i saved it

and now it dosent work

what the sigma

[teal viper]

You need to debug properly...

There's likely something resetting the reference.

[paper sable]

hey guys, im watching a video about handling slope movement, i've followed all of the steps but my character automatically jumps off the slope when i enter it for some reason, i dont think i've done anything wrong, so i dont really know why this is happening. does anyone know why this may happen? this is the code that handles slope movement:

    private void HandleMovement()
    {
        moveDirection = orientation.forward * moveInput.y + orientation.right * moveInput.x;

        if (OnSlope())
        {
            rb.AddForce(GetSlopeMoveDirection() * moveSpeed * 20f, ForceMode.Force);
            print(GetSlopeMoveDirection());
        }

        if (grounded) rb.AddForce(moveDirection.normalized * moveSpeed * 10f, ForceMode.Force);
        else rb.AddForce(moveDirection.normalized * moveSpeed * 10f * airMultiplier, ForceMode.Force);
    }

    private bool OnSlope()
    {
        if (Physics.Raycast(transform.position, Vector3.down, out slopeHit, playerObject.localScale.y + 0.3f))
        {
            float angle = Vector3.Angle(Vector3.up, slopeHit.normal);
            return angle < maxSlopeAngle && angle != 0;
        }
        return false;
    }

    private Vector3 GetSlopeMoveDirection()
    {
        return Vector3.ProjectOnPlane(moveDirection, slopeHit.normal).normalized;
    }

[teal viper]

Adding some debug rays to visualize the involved forces and directions would be useful to debugging the issue.

[acoustic sequoia]

So this is my debug menu. I can add a new 'row' at any time and i want to plug in my code to interact with it, to and from the debug menu.

[teal viper]

What I'd do is bind the debug menu directly to the character and update the values in update. To way events could get a bit messy with recursive bugs that might need extra redundant code to avoid.

With update, you'll make one or the other manage the values. And dirty flags or timestamps can be used to determine who's value is up to date.

[acoustic sequoia]

so you are saying to update the debug menu with my character manager script so that the menu correctly reflects the players stats.. how should i update the character stats if i change the debug menu?

[paper sable]

i've added debug rays for the normal move direction and for the slope move direction and they seem to be good. my character jumps off the slope as soon as i get on, and i think this may happen because the force that is being added while on a slope is too big

[teal viper]

If you change the menu, unbind the previous menu, and bind a new one.

[teal viper]

Then maybe the issue is with the jump logic? Can you share it as well?

[teal viper]

Ideally, you should debug the final forces/velocities that you apply to the actual rb. Then break it down from there.

Just the movement and slope normal are barely enough info.

[pallid kite]

Hey, I'm currently having an issue where my prefab that has a worldspace overlay of a text input field not taking any input even when I click it. This doesn't seem to be too common of an issue, but I've been stuck on it for the past couple hours on how to fix it. Can someone help me possibly debug this issue?

[teal viper]

Start with sharing a screenshot of the instantiated prefab and your setup overall at runtime.

[pallid kite]

Sorry for the delay, tried debugging a bit more

Admittedly, I'm a bit confused on what a good screenshot would be for showing you my runtime

[teal viper]

You need to select the instantiated prefab in the scene. And take a screenshot such that we can see the relevant components in the inspector.

[teal viper]

This is not an instance of the prefab at runtime.

[pallid kite]

I'm sorry I'm still a bit confused, do you want me to run and then screenshot?

Just to confirm we're not allowed to screenshare too? I was thinking that could help to debug

[teal viper]

Yes. Run the game. Get to the point where it's supposed to show/work. Select the object in the scene. Take a screenshot. Switch to the scene view. Focus on the canvas of the object. Take another screenshot.

[teal viper]

No. But you can share a video.

[pallid kite]

Okay, going to create that really quickly

[paper sable]

i fixed the issue, i forgot to set the slope's layer to ground so the grounded bool was false while on a slope, and if grounded is false the rb's drag is set to 0 which was for some reason causing the character to jump off the slide

[teal viper]

Many people answering here are doing it from mobile whenever they have a bit of time. They wouldn't have the means nor the time for a screenshare.

[pallid kite]

Ah that makes sense then. Here's a screenshot of what I think you're asking of me... How do I get the jar to still show within the prefab screen, I keep losing it

[teal viper]

I don't need to see it within the prefab mode. I need to see it at play mode.

[pallid kite]

Okay, getting that right now

I hope this helps?

[thin birch]

Hi! apparently the final for loop gives me immediately the "Object reference not set to an instance of an object" error... I provided the objects in the scene and cannot seem to understand why this is happening...

    public GameObject Sun;
    public GameObject Bg;

    private Vector3[] _startPos;
    private float[] _widths;

    void Awake()
    {
        
    }
    
    void Start()
    {
        for (int i = 0; i < Clouds.Length; i++)
        {
            _startPos[i] = Clouds[i].transform.position;
            _widths[i] = Clouds[i].GetComponent<SpriteRenderer>().bounds.size.x;
        }
    }

[short hazel]

The exception message will contain a stack trace which points to the exact line of code the exception was thrown on, post it here

Multiple things could be null in here

[thin birch]

the exact line is the first line of the for loop

sorry

[short hazel]

Okay so Clouds was null

[thin birch]

yea it appears so... but adding a print(Clouds[i].name) before does return the correct name

[short hazel]

So Clouds isn't null

First line of the for loop is for (...)

Right?

[thin birch]

oh no sorry I mean inside it

_startPos...

[short hazel]

Ah I see, it's _startPos

[thin birch]

yes

[short hazel]

Yeah, it's private

You need to instantiate the array yourself

[thin birch]

I see, thank you

[dreamy tide]

@short hazel brother

[short hazel]

What?

Pings and refueses to elaborate, great lol

[snow warren]

debug menu looks a bit futuristic lol

[thin birch]

all works, guess I should learn more about the c# basics in the meantime lol

[burnt vapor]

You should always make sure to validate public fields in case Unity or another piece of code modifies it. I suggest you place a null check at the start of your Start method that checks the gameobjects are set, or Debug.Assert if you only want the assertion to be done outside of builds.

Same goes for checking cloud instances

Even if they are private it doesn't hurt. Debug.Assert is stripped from builds so it won't hurt performance

[thin birch]

ended up solving by declaring the array sizes

[teal viper]

If you look at the hierarchy carefully, you'll see that the canvas with the input field is deactivated:

[minor radish]

What's wrong with this ?

[rough lynx]

You missed the s in spawnPipe

[minor radish]

Thank you but the mistake is still here

Anywone ?

[queen adder]

. between transform and rotation.

[burnt vapor]

You are required to configure your !ide in order to be helped. Apart from that a configured editor also helps you with your issue.

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[burnt vapor]

Pick the link that represents how you downloaded Visual Studio and follow the steps ☝️

[burnt vapor]

Please don't help users with their issue when their editor is not configured. Have them configure it first.

[valid violet]

@minor radish use Instantiate(pipe,transform.position,Quaternion.identity);

[burnt vapor]

Same to you, please don't help users with their issue when their editor is not configured. Have them configure it first.

[gilded canyon]

Also along with configiring the ide ln34 says Pipe not pipe

[burnt vapor]

This code has a lot of issues, and these will be made clear once they have configured their editor

And I ask again you don't help, period. If you decide to give the answer anyway most people just tend to continue their code rather than chore and fix their editor so this doesn't happen again.

[gilded canyon]

im pretty sure the game wont event run withour ide being configured

[burnt vapor]

It will

[gilded canyon]

i could be wrong though

[valid violet]

how did they make editor not configured on instalation?

[burnt vapor]

The editor is merely an analyzer, and Unity will compile the code if compilation is required on playing the game

[burnt vapor]

There are multiple steps required to configure an editor, including downloading the correct workload and setting VS as the external editor so Unity can open the right context. All is explained using the links in the [bot message](#💻┃code-beginner message).

[minor radish]

How to do that ?

[burnt vapor]

See the [bot's message](#💻┃code-beginner message)

Pick the one best suited. I assume it's either VS installed through the hub or manually.

[green flame]

Hello! Is there a way to "reset" an existing ScriptableObject by it's default value ? I tried 2/3 things but 0 success ^^

(from another scene btw ^^)

[minor radish]

so I have to download visual studio or what ? Cause I have already install it and the bot teach me how to install or do you want me to uptade it ?

[burnt vapor]

If you already have it installed, you follow the other steps and ensure you have the same setup

Specifically with manual installation, you must make sure the workload is installed and the external editor is set to VS.

[finite dove]

try exit to safe mode, or try to recompile the project.

oh i just saw the comma

[minor radish]

What do you mean by recompile ? As for the coma I have already fix it but a new error is appearing. For now I'm trying to configure visual studio to get help

[finite dove]

it's case sensitive so Pipe and pipe its different, you should configure the vs like fused say to make your life easier.

[burnt vapor]

Please configure your editor instead of fixing the issue. Your editor will point out the issue once configured

[frail wind]

guy i got trouble with player or spike collision because the player just go through the spike without any single collision occur. (unless i jump). i also sent the screenshot of the player code, the spike code, and both of the inspector in unity.

[minor radish]

Where I should find common7/IDE

[wintry quarry]

You're moving your object directly via the Transform, which bypasses the physics engine entirely.

[wintry quarry]

Certainly not in your documents folder

[frail wind]

then how do i fix it?

[wintry quarry]

"inside your visual studio installation directory" as it says

[minor radish]

I'm in it but where exactly ?

[frail wind]

(also rate my coding skill along the way lol)

[wintry quarry]

Rewrite your code to move the object via the physics engine instead

[wintry quarry]

Early beginner

[frail wind]

ok let me search it online

[wintry quarry]

Not according to that screenshot. It would be in program files

[finite dove]

try to learn SOLID it would be good for you.

[minor radish]

Can you be more specific should I change Pipe to pipe I don't understand what you mean

[burnt vapor]

Stop trying to fix your issue and just configure the editor

Things like this are things your editor helps with, not other users

[minor radish]

Thank you I found it

[minor radish]

I found devn and I open it and nothing happens why ?

Nothing guide me yet

[burnt vapor]

Visual Studio is already the external editor according to this screenshot

So the next step is to install or update the Visual Studio Editor package

[frail wind]

does [transform.position += (Vector3.left * anyNumber) * Time.deltaTime;] actually not moving the object but Rather teleporting the object?

[frail hawk]

yep, it changes the position, if you want proper physics you would have to use some rigidbody movement instead

[frail wind]

how do i do it then?

[cosmic dagger]

Yes, assigning the position will teleport the object to that new position . . .

[frail hawk]

Addforce / velocity / moveposition (not really accurate)

[frail wind]

that explain why the player just go through them
