[shell scarab]

i also said "for example"

[spring creek]

"if Vector2s are not serializable to a file" I don't see you say "when they're not marked as serializable"
That is where the confusion came from. For me at least

[shell scarab]

i didn't know that it's YAML

[quartz folio]

What case are you talking about when you say they're not serializable, there are thousands of serializers

[cosmic rain]

Maybe share the code that you use to serialize it.

[quartz folio]

That doesn't mean anything

[shell scarab]

the case when you try to serialize a Vector2 to a file. I'm not sure what you mean. I know you can pass a serializer (i forgot exact name) when serializing but I didnt see anything built into unity. I was not trying to use the JSON serializer.

[quartz folio]

Saving what to a file, what format was it serialized into before you decided to write it?

[shell scarab]

a Vector2

I was trying to serialize a Vector2

how many times do I have to say it

[quartz folio]

That's not a format that can be written to disk, that's a type

[cosmic rain]

Serializing means converting the data into a format that can be saved to a file. Whether it's binary or text. There are many ways to do it. Just saying "saving to a file" means nothing.

[cosmic rain]

how were you trying to serialize it? Share code.

[shell scarab]

my bad. I first tried to just serialize the Vector2 to a file using a Binary formatter. I also tried to serialize it to a byte array and write that to the file.

[quartz folio]

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

[cosmic rain]

Share the latest code that you have problems with and we'll go from there.

[shell scarab]

yes I know it is not good for security, the compiler literally warns you of that.

[shell scarab]

I don't even need it anymore. This is not a "help me with my code" question.

this is a "how is it done" question

[cosmic rain]

Well, then we can't answer your question, because it seems to be specific to your use case.

[quartz folio]

You pass it through a sensible serializer like Newtonsoft.Json, and write it to disk

[spring creek]

They want to know how it's done in a SerializableObject I guess...

[quartz folio]

In the case of Newtonsoft you also need converters because of the way the type is structured, and I posted those earlier

[cosmic rain]

The simple answer would be: Vector2 is serializable by json and yaml by default, so it can be saved as part of an SO.

[quartz folio]

Well, as that's editor-only and is written in C++ there's no answer that can be given

The YAML serializer reads the data, formats it, and writes it to disk. Just as any serializer does. Is there an actual question here?

[shell scarab]

I guess not knowing how something is serialized and asking how its done is not a question

[quartz folio]

Well you've been answered then, many times

[thick socket]

After 1 hour of debugging

Im finally free

[warm aspen]

@shell scarab I think some things would be cleared up if you shared the code that tries to save it to a json but gives an error

They are saying it is serializable, so something gives

[shell scarab]

I wasn't trying to serialize it to json, I was just asking how it's serialized when it's not marked as serializable. I guess the confusion came from me saying "to a file", because I knew they were serializable because they have to be to appear in the inspector.

[warm aspen]

So the question is why are they not marked as serializable?

[quartz folio]

That attribute is a hint for certain serializers, but is not required for many, and Unity does not require it because Vector2 is a built-in type that they natively support without the attribute.

[spring creek]

I guess my confusion came from thinking you thought they were not able to be serialized at all. But you meant universally serializable without an attribute?

[shell scarab]

I suppose. I was just curious about it, but the treatment bc I didnt know some things just turned me off from wanting to know. They aren't marked as serializable, so I thought they weren't serializable. But they're serialized to the inspector. Which is why I asked to a file. There wasn't a need to just make fun of me for saying they aren't serializable when they literally are not marked as serializable. My mistake for thinking this is a place where I can ask questions without being made fun of. Clearly there was a knowledge gap.

[spring creek]

Tbf, you were immediately flat out refusing everything we were saying. I felt hostility from you first.
BUT, I will apologize, because I did make a sarcastic joke and that wasn't fair. I don't mean to turn you off from learning

[cosmic rain]

I think you're jumping to conclusions that everyone here is out to get you. No one made fun of you. We were just trying to lead you to clarify your question or the context of it.

I literally can't find anything offensive in the conversation.
Aside from maybe excessive reaction emojis...

[warm aspen]

Looking from outside I felt that you guys were being unnecessarily dismissive of his questions and not making an effort to understand what he was trying to ask or to further explain what you were answering

[spring creek]

"try to serialize a Vector2 to a file"
"they are not"
"I guess you guys can't read"
"how many times do I have to say it"

I felt one party was the most aggressive. But ok
We tried to clarify, and correct in the beginning, but there was a hard refusal to help us understand
Our earliest comments were all just trying to understand where they came to that idea. Because all of us have serialized Vectors

[warm aspen]

Is it or is it not marked?

[shell scarab]

I meant to say trying to serialize a Vector2 to a file, sorry. But the immediate responses made me feel the need to be defensive.

[cosmic rain]

Looking at the source code now, I realize that it is not marked.
Something new to learn.

[warm aspen]

So if you said something and someone who knows more than you said you're "clearly" wrong when you are not even that wrong, how would that make you feel as a beginner?

[cosmic rain]

I guess if an appropriate proof was provided early on, it would've solved a lot of the issues in the conversation.

[thick socket]

like they are helping and I need it 😄

You will take a little "abuse" at first

[cosmic rain]

There might've been an issue with my response. I admit. But it all would've been way simpler if there was actual code provided.

[thick socket]

builds character

but dlich is pretty great and has helped me out a bunch for sure lol

[warm aspen]

Right!

[thick socket]

I haven't followed convo at all

but Sasquatch B Studios seems up to date and has great info imo

worth watching some/all of his vids 😄

[warm aspen]

Cool

[thick socket]

spent today redoing all my player and enemy AI to make it scriptable objects and my work will be so much faster now lol

[quartz folio]

Posting something without context that is wrong, and doubling down in the face of others is a fast way to make people annoyed

[shell scarab]

Except you didn't ask for proof. Next time if you don't understand a question or it needs more info, a simple "I don't understand your question can you clarify" would suffice. Also, I don't see anything about this channel being only for questions with code you have written, it says "general coding concepts in Unity".

I felt I had all the context. I didnt know enough to provide the full context. Which is why just asking for more would have been good since there was a knowledge gap.

[spring creek]

"Who said they're not?"

"Serialize how? There are many ways to do it."

"https://github.com/jilleJr/Newtonsoft.Json-for-Unity.Converters"

"The certainly are. Saving a position vector is one of the first things someone would want to save
"My player was HERE when they left""

These are ALL polite versions of that imo.

I'm truly sorry if it came off differently though

[cosmic rain]

I asked leading questions many times, but you didn't respond to them:

dlich — Today at 12:00 PM
Who said they're not?
Heroshrine — Today at 12:00 PM
try to serialize a Vector2 to a file

dlich — Today at 12:00 PM
Serialize how? There are many ways to do it.
Heroshrine — Today at 12:01 PM
they are not

dlich — Today at 12:01 PM
What makes you so confident about it?
Heroshrine — Today at 12:02 PM
because when you try to serialze a Vector2 to a file it literally produces an error saying that the type isnt marked as serializable.

Maybe the last message gives some hint, but it's hard to believe it without actual code, error messages.

[thick socket]

Tldr: always post code

[quartz folio]

There's nothing to learn, the attribute doesn't do anything functionally, it's entirely up to the serializer to care about it at all

[warm aspen]

It's water under the bridge

[spring creek]

I hope so. I DO feel bad. I was trying to just give an example of serializing a Vector

[warm aspen]

It was just a lot of communication mishaps

[cosmic rain]

I mean, the fact that it was not marked is something new for me.

[warm aspen]

No one's fault

[shell scarab]

I meant to say "trying". I already apologized, but again I am sorry. I thought it would be known they aren't marked as serializable. I understand the "they are not" is not a good response, I am sorry. I didnt know they could be serialize without being marked as serializable. Again, I don't see anything saying that I need to have a question regarding something I programmed, therefore I did not have code as it was not a "my code is broken plz help" question but a "how do they do this" question.

[thick socket]

Ive got to serialize my massive playerInventory soon...here is to hoping everything has been setup right and I dont have a random "un-serializable" class

[warm aspen]

Using dictionaries?

[thick socket]

Yeah, I think I know the json to use that can handle that tho

If not you will see me here soon lol

And by soon I mean maybe a week or 2 😄

[cosmic rain]

You can literally take an instance of a class, and save one of it's fields to a text file and that would be considered serialization + saving:

class A
{
  public int fieldToSerialize;
}
class MySerializer
{
  void SerializeA(A a)
  {
    File.WriteAllText(path, a.fieldToSerialize);
  }
  //Deserialize - overwrite or create a new instance and read the value from a file
}

[warm aspen]

There are lots of tutorials on YouTube on how to make serializable dictionaries

[quartz folio]

If you use a third party json library they will tend to be able to serialize dictionaries with no work

[livid terrace]

all I need to store are int bool and float so I'll probably figure things out

[nimble dome]

If I have a few different action maps in my input system, lets say play and pause, what is the best way to get each script using an instance of the input system to reflect the current state of the game?
If I have a input manager, and when the pause button is pressed i want to disable the input system on all scripts using the play action map, and enable all input systems on scripts using the paused action map, how do I go about doing this? Do I use an event?

[unborn fern]

so im having this problem after deleting plasticSCM from my unity game:
NotConfiguredClientException: Unity VCS client is not correctly configured for the current user: Client config file C:\Users\user\AppData\Local\plastic4\client.conf not found. Please execute 'cm configure' to perform a text mode configuration or 'plastic --configure' for graphical mode.
is there any way to get rid of this?

nvm i fixed it

[frail shoal]

This code works fine. I simply put in the reference gameobject for the SwitchUnit in the inspector.
But what if I want SwitchUnit to be more than 1 object?
Maybe objects that has a certain tag or rather any gameobject that is specifically in that position in the if statement?
What do I write?

[fervent furnace]

dont cross post, do you know what is array? btw if you have multiple switchunit then you have to change the second if statement

[frail shoal]

what exactly do I write?
I know a bit about arrays but not enough to do this apparantly

[cobalt scarab]

what do you guys think of this approach ? I'm making dictionary for buffs and debuffs some of them have Reference to the dictionary and they can self remove after some time

 { 
     public  event EventHandler<ModifierArg> ModifierHandle;
     public new void Add(string key,IModifier item)
     {
        
         base.Add(name, item);
         ModifierHandle?.Invoke(this, this[key].ModifierArg(true));
     }
     public new void Remove(string key)
     {
         ModifierHandle?.Invoke(this, this[key].ModifierArg(false));
         base.Remove(name);
         
     }
 }```

[frail shoal]

I tried doing this, it didn't work.

Just want SwitchUnit(it's a game object) to be every single game object in the Unitprefabs array

Unfortunately Unity doesn't understand quantum physics where an object can be multiple things at the same time

oh shit, maybe I should do a raycast

[somber nacelle]

you should go through the basic c# courses pinned in #💻┃code-beginner to learn how variables and collections work

[nimble dome]

Can you explain in more detail what you mean?
Do you want an array that contains all SwitchUnit gameobjects in the scene?
I also agree with boxfriend that it might be good to watch a quick tutorial on variables and arrays in C#

[frail shoal]

I watched quite a few C# tutorials on arrays just now

Still can't do it.

[somber nacelle]

what are you trying to do? because the code you posted before is almost nonsensical in what it does

[frail shoal]

Basically, this code works. But the problem is that I have to assign SwitchUnit from the inspector.
Instead of doing that, I was thinking of making an array and adding every single Unit in my game into the array(which are all gonna be considered SwitchUnit in my inspector)

It's a card game mechanic where your card(A) can switch positions with any other card(B) that is adjacent to (A).

I want to make it so that you can only switch with cards that you control and not the opponent's but that comes later

So if card (A) attempts to go left and there is a card(B) in it's desiredlocation, instead of the method failing, the two cards will switch positions

[frail shoal]

something like this

[mild coyote]

Is it possible to pass a delegate/action as parameter?
Something like this?

//Class ClassA
public void RegisterAction(System.Action<float> action)
{
  action += DoSomethingHere;
}

void DoSomethingHere(float x)
{
  Debug.Log(x);
}

//Class ClassB
System.Action<float> action;
ClassA classA;
...
classA.RegisterAction(action);
action.Invoke(0.5f);//null reference error

Or are there any alternative to that?

[simple egret]

ClassB should expose an event Action<float> instead

Then ClassA can subscribe to it

[somber nacelle]

what SPR2 said, but also delegates are immutable. every time you += it, it creates a new instance of the delegate. like how strings work

[simple egret]

Then I guess your RegisterAction method could take a ClassB parameter, and subscribe to the event

[mild coyote]

I see... so it's not possible doing that way...

[mild coyote]

Seems like this is a good alternative, I'll try this instead, thanks

[nimble dome]

In terms of the array part. If the amount of switch units stays the same you could manually add them into a list in the inspector, or if not, add them at runtime through code.
Lists are the best for this.
This will allow you to add the objects manually in the inspector.
public List<GameObject> switchUnits = new List<GameObject>();
This will let you add items via code. So you could instantiate them and them add them during runtime.
switchUnits.Add(your gameobject);

You could then reference each item via its index or other method

[regal epoch]

I have this code

using System;
using UnityEngine;
using Unity.Netcode;
using UnityEngine.Networking;

public class RandomNumberGenerator : NetworkBehaviour
{
    private System.Random randomGenerator = new System.Random();

    [SyncVar]
    private int randomValue;

    // Server initialization
    public override void OnStartServer()
    {
        base.OnStartServer();
        GenerateRandomNumber();
    }

    // This method generates a random number and syncs it across all clients
    private void GenerateRandomNumber()
    {
        // Generate a random number (e.g., between 1 and 100)
        randomValue = randomGenerator.Next(1, 101);

        // Sync the randomValue variable across all clients
        SetDirtyBit(1);
    }

    // This method can be called by a client to request a new random number
    [Command]
    private void CmdRequestRandomNumber()
    {
        if (isServer)
        {
            GenerateRandomNumber();
        }
    }

    // Client-side method to handle the received random number
    [ClientRpc]
    private void RpcReceiveRandomNumber(int newValue)
    {
        // Handle the received random number on the client-side (e.g., display it)
        Debug.Log("Received random number: " + newValue);
    }

    // Example of how to request a new random number from a client
    private void Update()
    {
        if (isLocalPlayer && Input.GetKeyDown(KeyCode.Space))
        {
            CmdRequestRandomNumber();
        }
    }
}

but somehow it's not working. I don't know why. Could somebody look at it?

[somber nacelle]

you need to be more specific about what exactly is not working. also #archived-networking

[regal epoch]

oh okay thanks

[cobalt scarab]

event handler cant do the job? using eventArg

[pastel halo]

Hey, I'm trying to solve this difficult twin-stickish control scheme and I'm having difficulty figuring out the rotateTowards/LookAt code.
The idea is that the horse will face the direction you keypress in (using input.x/input.y from input actions). those values always return absolute -1/1 or 0.71/-0.71

The problem is compounded since you are able to rotate the transform root (entire gameObject) and the WASD is only rotating the child visual (horse). It's dual rotation. Trying to debug out the values to "look at" changes. It seems
Here's the code of just the input: https://pastebin.com/5ZfaSubR
The parent Root rotation is just middle mouse + drag -> totalRotation += context.ReadValue<Vector2>().y)

If the camera didn't rotate, I'd have about half of it solved, since it does technically face the direction you keypress, while the parent transform root stays fixed.

the debug was outputting 0.71 and -0.71 as the diagonal, so I tried
if (inputVector.x == -0.71 && inputVector.y == 0.71)
toRotation = Quaternion.LookRotation(transform.forward + -transform.right, Vector3.up);
I was hoping that adding the two transform directions would create the inbetween diagonal so you can face diagonally while running that direction

[summer oracle]

Hi guys,

I have a question

How is OnApplicationPause and OnApplicationFocuscalled in Editor, Android and IOS, and what are their execution orders.

've been messing around with them for a while and there is no clear documentation whatsover on this, which makes me feel a lot confused

[frail shoal]

I figured it out

The answer wasn't arrays at all

It was raycast

I was supposed to shoot a raycast from the selected unit towards left, forward, back etc so that the secondary unit gets selected so I can have 2 units

[stable warren]

is there anyone that can make a unity game with me

[fervent furnace]

no

you should post it in jobcolla !collab

hey me and my friend are wanting to make a game like bit life using unity where have some hardship with getting the basic done like the aging system can any one help with that, i feel like i tried everything but we cant achive that bitlife aging and the years going up fase

[knotty sun]

A) This is a Code only channel
B) Don't cross post

[left knot]

no hlep

[spring creek]

I saw your question there and I didn't understand it. Rather than referencing a game people may not know, describe the behaviour you want.
Aging can just be a number you increment after a timer completes. Use coroutines?

[steep herald]

Struggling to come up with a player FSM logic that makes sense.

For instance, if the player can both jump and attack at the same time, then since only a single state can be active at a time, one of those 2 can't be a state. Which one? How do you reason about this?

[swift falcon]

How can I detect the model of gamepad connected to Unity?
I need to figure out if the model is Playstation so I can change the button names

[knotty sun]

if you use an enum with the Flags attribute you can have multiple states at one time

[steep herald]

@knotty sun Maybe my lack of experience with FSMs but I feel like that'd be a nightmare. If states use self contained logic(mine do), they'd need to cross validate with other active states to determine whether or not they can effectively change.

[swift falcon]

(Using the old input system btw)

[knotty sun]

true, each state would need logic to behave appropriately depending on the combined state
i.e. Jumping, Crouching and Attacking

[warm aspen]

I don't think attacking should be a state. I also wouldn't make jumping a state. I would make walking and falling states. You can attack on both states. You can jump when walking, which changes state to falling, and you might be able to double jump when falling (if that's a thing in your game)

[steep herald]

@warm aspen Yeah, seems like a more sensible design. For jumping, all relevant logic is performed as the input is processed, so this will work perfectly.

For attacking, it seems not so great since attacking is done over a period of time. (e.g. sword swing where there's multiple collision detection steps)

This means that I'd have to, within the attack, constantly keep track of the state to make sure I haven't entered a state that would conflict with the attack (e.g. dead)

I mean, it's not the end of the world but my character controllers have always been absolute messes in the past. Was hoping to do better this time 🙂

All being said, thanks for your input

[warm aspen]

I don't think you'd need to keep track of the state within the attack. Instead you could make so that states that should cancel the attack do that when entering the state, if is attacking

[marsh marten]

Not sure if this is proper channel but maybe someone will know the answers

Autocomplete sorting - it shows me a lot of unnecessary suggestions, especially when compared to VSS - how I can get rid of them?

(is it extension's fault? I have active C#, C# Dev Kit and Unity) (edited)

[simple egret]

It probably picked up these because the casing matches exactly. If you wanted transform, you need to keep the first letter lowercase

It's the same in VS, it also now suggests types from unimported namespaces by default, but this can be disabled

[marsh marten]

Yeah, sorting by name is ok, this one I get. Looks like it loads up too much unnecessary suggestions - I don't know why
I've opened older project in VS2019 and it shows me only those suggestions that I need.

[simple egret]

Yeah the VS2022 and VSC equivalent of this would be the same as if you hit this

It's now enabled by default

I don't know if it can be disabled in VSC - search the C# extension settings for a "show items from unimported namespaces" option, or anything named similarly

[marsh marten]

That was exactly that, thank you sir 🙂

I have bonus question - is it possible to auto insert space after accepting suggestion with Spacebar?
That's another thing that I think is default in VS, but I can't find setup in Code 🤔

[desert wind]

For my project, I am trying to make my player automatically jump when they touch an object that is part of a certain layer, the problem is I believe I am referencing it wrong. Here is the code.
https://paste.ofcode.org/b4H6VTTpQeTFU6caRZsMgB

[mellow sigil]

It's comparing a layer and a layer mask. They're different things.

Try if((whatIsWall & (1 << collision.gameObject.layer)) != 0)

[heady iris]

LayerMask could really use a nice MaskFromLayerIndex method on it

i just don't like seeing the bit shifting for some reason

it could also do with union/intersection and "is empty" queries, too

wouldn't be hard to make extension methods...

[knotty sun]

there is this https://docs.unity3d.com/ScriptReference/LayerMask.GetMask.html
Mask from name(s)

[heady iris]

Right, but this is about getting a mask from a layer ID

I guess you could go ID -> name -> mask

[knotty sun]

then you bitshift

[heady iris]

ye

I just find it to be unintuitive to look at, compared to everywhere else that you use named methods on LayerMask

[knotty sun]

easy way to solve, make a struct for all 3 values

[west mesa]

what did you say

[knotty valley]

make a reference to your inventory component in your pickup weapons script

Hello, I am using a ScriptableObject for an audio container, nothing very fancy, originally came from one of Jason Weimann's courses. In one project I can edit multiple instances of this ScriptableObject, and in another project I get the "multi-object editing not supported" message when selecting the same (2 or more) objects. Both projects are on 2022.3.8f1; any ideas why this might be happening?

[buoyant ermine]

so, I have a bunch of invisible unity buttons that need to move about the screen and change size based upon what video is playing, all while being unclickable until pause? any ideas?

[sage latch]

Do you have an custom editor in the one but not the other?

[sage latch]

Button.interactable to make them unclickable. For moving them around a tweening library like LeanTween is nice

[frail ibex]

Hello, i have trouble i'm trying to do a save system, for the file it seems to work pretty well, but i can't manage to get a hold on my variable to save the right stuff in the file --> https://paste.ofcode.org/EJXi3ibSB59dPnGnLNkgCJ

[sage latch]

Looks like you're trying to save the whole PlayerMovement component

unfortunately that doesn't work

[knotty sun]

you are declaring and instancing Savedata but you never fill it with anything

[frail ibex]

Sadly i can't get a touch in it's properties somehow

[sage latch]

Wdym?

[frail ibex]

WE are a group of 3 person working on the project and i didn't code PlayerMovement class myself and when i touch something like putting a properties as public static it break the whole code that's link with

Get or Set doesn't seems to work either

[sage latch]

What properties do you need?

Just do player.PROPERTY = ..

(provided they're public, but you could just make the public if not)

[frail ibex]

When i set public it break the thing, some are in private

To be sure the code for the file itself is good ?

[knotty sun]

no

[sage latch]

What's stopping you from making the properties public?

[frail ibex]

Error

[sage latch]

What error

[frail ibex]

sec i'm on my phone

[frail ibex]

What's the problem ?

[knotty sun]

data will always be as good as empty, so what's the point of saving it

[sage latch]

They're probably mutating it from somewhere else

[knotty sun]

SOLID

[sage latch]

well

first it has to actually work

[frail ibex]

I have PlayerMovement file somewhere, which has data i wanna keep

[knotty sun]

post playermovement script

[frail ibex]

It's kinda huge though, it' a mess even i don't want to read it

[sage latch]

What do you want to save?

[knotty sun]

we can't help you with it if we cant see it

[sage latch]

that's the important part

[frail ibex]

Like coin or Health or player position

https://paste.ofcode.org/6BTETCDL7zrnekX2ju25S4

Friend made it like that, don't ask why he didn't split in other files

[sage latch]

[System.Serializable]
public class SaveData
{
    public int coin;
    public float health;
    public Vector3 position;
}
```You have to pull them out manually and apply them in `Load()`

You should be able to set playerHealth to be public

[knotty sun]

Ok, it's a Monobehaviour, you cannot serialize that

[frail ibex]

How can i fix that ?

[frail ibex]

I don't manage to pull them, even as public

[sage latch]

Show how

[frail ibex]

I showed it already

Ah

[knotty sun]

make another class and copy the variables from PlayerMoveMeny to that class then use that class in your SaveData

[sage latch]

You have to get a reference to a PlayerMovement component, not just use the class name

[knotty sun]

that is not how you reference variables from a class

btw I cannot see a single reason why changing any private to public would break anything or cause an error

[frail ibex]

Mh, it break in an another file

[knotty sun]

doubt

[frail ibex]

GetComponent<PlayerMovement>().nbCoin += qg.quest.gold; was this one

[knotty sun]

that is public

[frail ibex]

Then i'm doing it wrong

[knotty sun]

probably not finding the PlayerMovement component or qg is null or qg.quest is null or qg.quest.gold is a incompatible data type, did you bother to check any of that?

[frail ibex]

Nah it made the error when i put nbCoin as public static

[knotty sun]

cannot be static

[frail ibex]

That the only way i found to pull it out, but it didn't work anyway

[knotty sun]

why would you even think of making it static?

this GetComponent<PlayerMovement>().nbCoin is how you pull it out

[frail ibex]

No i tried it and not working either

[knotty sun]

did you do the GetComponent on the correct gameObject?

seems to me like you need a lot of !learn

I have this kind of GUI layout where I navigate to various screens by clicking different buttons. Works well for touchscreens and mouse.

But now I am trying to make it work with keyboard/controller and having a hard time keeping track of which button on which panel is currently highlighed/selected so pressing ENTER key or X button triggers the event.

Hello! I have a game where thew player can create levels and I want them to be able to save the levels in the form of JSON files locally. The game is both PC and android, is there a common prefered way to save those files? Or a different way by platform ?

[sage latch]

Application.persistentDataPath

Be sure to also use Path.Combine when making paths to make it compatible with every os

[mossy ravine]

Fantastic, this is exactly what I was looking for, than you so much @sage latch !

[frail ibex]

Sorry to insist sadly, i don't have much time to pass on the learn unity yet, i'll take time for it when i can. If i can get learn just for my problem right now i'd be happy enough please.

[sage latch]

You have to get a reference to the PlayerMovement component, but it's on another gameobject

easy way is to make a public field of type PlayerMovement in the SaveSystem

then you can drag the player in

[frail ibex]

public PlayerMovement player = new PlayerMovement(); wasn't this meant to do this somehow ?

[sage latch]

You shouldn't create new components with new. Plus, you need the PlayerMovement that is attached to the player

[frail ibex]

If it's that, was already the case

[sage latch]

Kind of

SaveData shouldn't have the reference to the PlayerMovement though, since you can't serialize a component

Put the PlayerMovement field in SaveSystem instead, and the data you need to store in SaveData (such as coin and health)

[frail ibex]

Yes i checked the JSON only getting ID

[sage latch]

Yeah

[frail ibex]

Ok, i still get error though

Asking for reference, SaveSystem.player

[versed loom]

does someone know how to remove those 2 <No Name> file templates?

[frail ibex]

https://paste.ofcode.org/uWaVtsH3zNraLfxZ36BHS5

[sage latch]

SaveData doesn't know of player

put that code in Save() instead

[cobalt scarab]

why there is public class called SaveData?

[frail ibex]

To put data i want to store in

[cobalt scarab]

ok i see now what you are doing , saving coins amount that is in the playerMovment class right?

[frail ibex]

Yes

[frail ibex]

Putting PlayerMovement Player in Save() break everything

[sage latch]

I meant this:

    public void Save()
    {
        data.coin = player.nbCoin;

        string player = JsonUtility.ToJson(data);
        string path = Application.persistentDataPath + "/Save.json";
        Debug.Log(path);
        System.IO.File.WriteAllText(path, player);
        Debug.Log("Sauvegarde effectué");
    }

```It's a bit confusing that you define the json string as "player"

consider switching that

[orchid bane]

Resources.Load asks for folder name but how do I load a file with a specific name?

[frail ibex]

Ah

[sage latch]

Give it the path without the file extension

[orchid bane]

How would it help

[cobalt scarab]

you just type folder and name right? one sec let me check

[sage latch]

That's how you load files

https://docs.unity3d.com/ScriptReference/Resources.Load.html

[orchid bane]

So folderName/fileName?

[spring creek]

It asks for a path. The end of the path is the specific file name

[spring creek]

Yes

[sage latch]

yeah

[frail ibex]

@sage latch Ok seems to work

[cobalt scarab]

Resources.Load<FileType>("Folder/fileName");

[orchid bane]

Dosc tho: Pathname of the target folder.

[frail ibex]

Got the coin saved on the json

[sage latch]

??

[cobalt scarab]

if target in Resources folder without sub folder you just type file name

[orchid bane]

I was looking at Resources.LoadAsync

Do you think it's different?

[spring creek]

Where is that?
I see:
"Path to the target resource to load."
And "Loads the asset of the requested type stored at path in a Resources folder."

Edit: ah, that was already said, sorry

[sage latch]

I think it's specifically for loading a whole batch of stuff

[spring creek]

Different method. As they said and you know, so just reiterating

[sage latch]

The description says Asynchronously loads an asset stored at path in a Resources folder. so I guess they're a bit indecisive

[frail ibex]

So i just gotta do for Load(), player.nbCoin = data.coin; right ?

[cobalt scarab]

async load with task so you dont have to wait for the load to finish unlike normal load

[sage latch]

Yeah

After you load the data

[frail ibex]

Alright, thanks Bobbo !

[orchid bane]

Bobbo!

[sage latch]

thats me

happy sunday

[frail ibex]

My Load is in an another scene how can i retrieve my Player GameObject ?

[sage latch]

That's a harder task

[frail ibex]

Harder but possible ?

[sage latch]

Do you have to get the save data in the other scene?

[frail ibex]

My Load button is in an another scene that load the game which is in another scene

Basically, i have a Scene for the Main Menu, and a Scene for the Game

[sage latch]

Why not have the SaveSystem in the Game scene?

do you need it in the menu?

[frail ibex]

But the button for Loading is in the menu though

[sage latch]

If you call Load from Awake

You don't need a button to trigger it

[frail ibex]

So the button for changing Scene, and Awake that load data

[sage latch]

Yeah

[frail ibex]

Okay ! Thanks

Hey all, I'm having a hard time figuring out how to get the Timeline Signals to fire during edit mode. I found some examples online about using NotificationFlags, but I can't for the life of me figure out how to use it or how to make a script that could replace the original SignalAsset or SignalEmitter

Sooo any help or ideas very welcome

[robust osprey]

I definitely have custom editors, but they're in both projects and the objects themselves are fully editable. I did previous have a Unit Test framework in the new project (where multi-edit is not working). I got into such a mess with that, I had to undo it all and remove all the Assembly Definitions (even though the testing itself was great and worked). Anyway maybe in the undoing of it I broke something. Unfortunate! Thanks for the reply.

[heady iris]

oops, hit enter early

How do I load a json file in the project’s build? ie how do I target it via path?

[vital jackal]

I’m trying to get authentication set up and I’m a bit confused. There’s a method called SignInWithSteamAsync(string ticket, string identity, SignInOptions options = null) What am I supposed to pass in for identity and sign in options? Documentation says “identity of the calling service” for identity and “options for the operation” for the sign in options.

[heady iris]

Use a Text asset.

you could reference it, or load it from Resources

If you really need to have an actual json file on disk, then you'll need to put it in StreamingAssets

[heady iris]

That method creates the file if none exists.

I'm trying to get the metadata for my IAP so I can show the price to people before clicking the button. This used to be easy to access with the legacy codeless IAP but now I'm forced into using the new stuff. According to documentation, I have to access the IStoreController interface. I'm not particularly good at understanding interfaces but adding this one gives a lot of errors asking me to add a bunch of functions to my class to take care of the various things the interface can do. 1: Is there an easy way to automatically add all of these necessary functions and/or 2: Is there a way to use interfaces without it asking for all the functions (that I won't be using) to be added to the class?

Edit: Turns out right clicking on the interface's name and selecting the lightbulb actually adds the entire function set. Amazing. This answers my first question at least.

[flint kettle]

I'm trying to make a custom character controller for my 2D platformer, I have watched many of tutorial, they divided "player velocity" and "gravity" into two variables, one store player movement, another store gravity velocity, but when player jumps, "player velocity" will be (0,10) , and since gravity is independent to "player velocity", so (0,10) won't be reduce by gravity, how can I solve this kind of problem ?

[leaden ice]

You can only use constants as switch cases unless you're doing pattern matching

[nimble dome]

So do I just resort to nested ifs?

or rather else if

[orchid bane]

I'm creating objects in Edit Mode but how do I make them dirty so that I can cancel them later?

Undo.RecordObject looks like doesn't work on not created objects

[quartz folio]

https://docs.unity3d.com/ScriptReference/Undo.RegisterCreatedObjectUndo.html

[nimble dome]

You should be able to simply subtract gravity from player velocity in Update().
playerVelocity -= gravity * Time.deltaTime

[orchid bane]

Is there a similar thing for when creating a bunch of objects? So that I can cancel them all with a single Undo

[leaden ice]

Else if chain or a switch with pattern matching syntax https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/functional/pattern-matching#multiple-inputs

[nimble dome]

thanks ill look into it

[quartz folio]

Undos tend to automatically collapse if you do things at once

[orchid bane]

Which one would be suitable for recovering a deleted object?

[quartz folio]

https://docs.unity3d.com/ScriptReference/Undo.DestroyObjectImmediate.html

[flint kettle]

But in this way, when player stand on slope, the gravity will keep pull player down slope.

[nimble dome]

true but you could fix that with grounding

You would also want to stop subtracting velocity when you are grounded to it doesnt continue to drop even while on the ground

[flint kettle]

you mean set gravity to zero when grounding, so it won't keep subtracting velocity?

[hard viper]

are you working with slopes and a dynamic rigidbody?

[flint kettle]

kinematic

[hard viper]

nvm then. there should be many tutorials for that

i did work with dynamic ones, which is a lot harder

forces in general shouldn’t affect kinematic rigidbodies, including gravity

[flint kettle]

yes, so I need to code gravity by myself.

[hard viper]

that’s not hard. just use kinematic equations and basic physics

if you are on ground AND you shouldn’t be disconnecting (ie jumping, swimming, big force applied etc), set no gravity

[flint kettle]

Thank you for your answer, I will try it

Hey, im trying to work with the kiwicoder behavior tree, and im running into an issue where it wont accept public / serialized properties from the inspector. I dont know if anyone can provide some advise or if I'm just going to have to pony up for a real BT asset.
The issue is a little tough to but into writing but in short, its just like making a public or serialized property in a normal script, where it appears in the inspector and you can select an object of a specific type from the field. Except when you select an object from that field it errors out and says that there is a type mismatch, when you literally can't select an object of the wrong type

heres a video of it as well

Talking to ChatGPT I found a solution to the ever annoying task of using Compare Tag and not using the correct string name.

Just use this in an empty script:

https://gdl.space/toviyufuca.cs

Than when you create a variable using any string just have [TagSelector] [SerializeField] private string than your variable name.

In the inspector it will now have a drop down box using the already made tag list you made in the inspector.

I Understand most don't use compare tag but others that do might find this useful so there is no error mistakes and the only thing you need to add to your scripts is just [TagSelector] [SerializeField] to access it.

[torpid sand]

Any idea on this? 👀

[hidden parrot]

No idea but why would you want them to fire in edit mode

[torpid sand]

I'm implementing subtitles so that it'd be easy to tweak them in edit mode

I found a better solution though, making them with timeline tracks instead of signals

[gray mural]

public virtual IEnumerator Collide(ItemBehaviour collision, Vector2 expectedPos)
{
    print($"Collide - {name}");
        
    yield return null;
}

public override IEnumerator Collide(ItemBehaviour collision, Vector2 expectedPos)
{
    base.Collide(collision, expectedPos);

    print("yep, collided");

    if (collision.itemType == ItemType.Player)
    {
        print("yep, player");

        collision.transform.position = expectedPos;

        GameManager.PlayGame(false);
    }

    yield return null;
}

Hello, any ideas how to make override Collide not to be interrupted by virtual Collide ?

I need'em to be coroutines, I'll implement further logic after that

[hidden parrot]

Can you StartCoroutine it instead of calling it

I know you can yield startcoroutines, maybe thats whats happening here

[torpid sand]

Yeah just guessing, but maybe StartCoroutine(base.Collide(collision, expectedPos))

You might end up with two simultaneous coroutines tho

[hidden parrot]

I think that's the intended effect

[torpid sand]

So as frant said, yielding the base coroutine first might work

[hidden parrot]

I assume by interrupted he means the coroutine stops for the base coroutine to be called

[torpid sand]

It probably doesn't "stop", it just never gets properly started

[hidden parrot]

Right, interrupted is pretty unclear here
Anyhow, startcoroutine is the first thing no matter what

[gray mural]

oh, it seems not to collide at all

public override IEnumerator Collide(ItemBehaviour collision, Vector2 expectedPos)
{
    print("Hole - Collide");

    yield return StartCoroutine(base.Collide(collision, expectedPos));

    print("yep, collided");

    if (collision.itemType == ItemType.Player)
    {
        print("yep, player");

        collision.transform.position = expectedPos;

        GameManager.PlayGame(false);
    }

    yield return null;
}

it worked yesterday, gotta check my git commits that have broken it

[torpid sand]

Who's calling Collide to begin with?

[gray mural]

a player

[torpid sand]

How?

[gray mural]

protected void CallCollisions(ItemBehaviour[] items, Vector2 expectedPos)
{
    foreach (ItemBehaviour item in items)
    {
        if ((item.itemType & collisions) == 0)
            item.Collide(this, expectedPos);
    }
}

// Player.cs
CallCollisions(items, newPos);

[torpid sand]

Should that be a StartCoroutine as well?

This one item.Collide(this, expectedPos);

[gray mural]

oh, yeah, exactly!

I haven't mentioned it

thank you!

[torpid sand]

🙂

[gray mural]

now it works, what a stupid mistake of mine

[torpid sand]

Hehe it happens

Looking at your code snippets, there's nothing that requires them to be coroutines though. You sure you need them?

[gray mural]

thought it happened because of yield break before, then changed to yield return null, gotta change back so that it won't wait a frame

[gray mural]

yes, I'm gonna implement further logic right now

[torpid sand]

Alrighty

[torn eagle]

Might be a bit of a stupid question but is there a way to reference children of a parent class using GetComponent<>? For example if Potion derives from Item I would still be able to access it by saying GetComponent<Item>?

[torpid sand]

You can cast it

For example
(Potion)GetComponent<Item>()
or
GetComponent<Item>() as Potion

[torn eagle]

Ah my problem is I have multiple items

So like, if Potion and Stick were items I could reference either one through GetComponent<>

Actually I could probably just add self-destruct functionality through casting anyway

[torpid sand]

Hmm I don't really understand what you're after

You could cast as Potion or Stick?

[torn eagle]

Oh wait no that still wouldn't work

[torpid sand]

var stick = (Stick)GetComponent<Item>()```

[torn eagle]

 Component component = itemHolders[val].GetComponent<InventoryItem>();
        Destroy(component);```

[dusk apex]

What're you trying to do specifically?

[torn eagle]

Essentially trying to destroy any components of the Item class

[torpid sand]

What do you think are the "components of the Item class"?

[torn eagle]

Oh sorry of the InventoryItem class

[torpid sand]

Same question

[torn eagle]

Any script inheriting from it

[torpid sand]

Then your script basically should already work

[torn eagle]

It's not seeming to destroy it though so I feel like I'm goofin up somewhere

[torpid sand]

If Potion inherits from InventoryItem, and you find all components of type InventoryItem, it should return Potion as well

[torn eagle]

Wait oh my god I see my issue now sorry lol

I wasn't destroying it from the right object

I'm so sorry to waste your time oh my godd

[torpid sand]

Heheh

[urban lintel]

is it sensible to use a coroutine to reduce the frequency of calls that may(?) be expensive? I have a script that tries to find the enemy player based on certain conditions (distance, maybe sight of vision at some point) but i figured there's no real reason to run this every single frame and that running it like 5-10 times a second is enough, is running this on a coroutine and setting a wait for 0.1-0.2 reasonable?

[torpid sand]

I do that sometimes too, but it feels iffy

If it truly is a heavy operation, you might end up calling them in sync for multiple enemies and causing a lag spike whenever it hits

[urban lintel]

that's a good point, although i imagine that's still equally or less expensive than if it ran every frame too

[torpid sand]

Not sure about your level of development, but if you're not experiencing any issues with performance, my advice would be to not care about performance until you can visibly see a performance issue

[urban lintel]

yeah i'm far from having them as issues, just was curious if that's something people use them for or not

[torpid sand]

And once you do, use the profiler to see what is actually causing the perf issues

But a couple of raycasts every frame is nothing, if you're worrying about something like that

If your sight of vision area can be a box or a sphere, you could do it all with trigger colliders with OnTriggerEnter / Exit

(or a capsule...)

[vagrant plaza]

whats wrong?

[torpid sand]

Maybe .SetBool("IsJumping", true)

Any ideas why this method breaks unity (so that I have to close it via Task Manager) when there are just 13 items in itemData?

public void LoadLevelData(string levelId)
{
    LevelData levelData = GetLevelData(levelId);

    if (levelData != null && environment != null)
    {
        List<ItemData> itemsData = levelData.itemsData;

        foreach (ItemData item in itemsData)
        {
            GameObject newItem = Instantiate(GameManager.instance.GetItemByName(item.name), environment);

            newItem.name = item.name;
            newItem.transform.position = item.position;
        }
    }
}

this couldn't be performance issues, right?

it just spawns 13 GameObjects

[somber nacelle]

are you sure this is the code that causes the issue?

[gray mural]

yes, if I return; at the beginning of the code, it doesn't spawn objects and game isn't broken

I have just tried to spawn just 1-4 items and unity didn't seem to broke

[somber nacelle]

well it's either that you are spawning something that has an infinite loop or spawning something that spawns itself that spawns itself that spawns itself etc

[gray mural]

but it can't be because of performance issues?

[somber nacelle]

no, that wouldn't cause unity to completely lock up forever. that would just cause things like reduced frame rate

[gray mural]

I see, is there any wait just to pause the game when it breaks?

[somber nacelle]

use breakpoints

[gray mural]

in order not to restart unity every time

[gray mural]

I have used them already, I haven't mentioned anything strange

[somber nacelle]

use them to pause execution. you know, to stop your infinite loop

[gray mural]

but I don't know where my infinite loop is..

[somber nacelle]

then do nothing i guess, i don't know what you want me to tell you other than that you need to debug your code to find the source of the issue

[gray mural]

I have asked if there's any way to prevent unity from breaking without using any breakpoints

guess no then

[somber nacelle]

yeah you can prevent unity from "breaking" by not writing infinite loops. otherwise you'll need to use breakpoints and debug your code to find the source of your infinite loop(s)

[gray mural]

I see, I'll try to find them, thank you 😄

[thick socket]

do I need class to be monobehavior to use

_timer += Time.deltaTime;

[prime sinew]

I dont think so?

but if you plan to run that in Update, then yes?

you need MonoBehaviour to have Update

[thick socket]

Gotcha, was planning to make a class that does attacks in update

but a "helper" class that has all the code for each attack of attack that wouldn't need to be a monobehavior

[rain minnow]

You just need access to the Time class but this only works if used every frame, hence you'll need a MonoBehaviour class that runs this code for you in their Update . . .

[simple sable]

Hey. So, I have this enum declared as public, outside of any class, because I want it to be accessible from anywhere in my game, by all scripts.

This enum contains all the directions an entity in my game can face. However, the only problem I'm facing is how to associate a Vector2 with each of those directions. I want to be able to access the correct Vector2 that an entity should use to move, based on the direction. I'm just not quite sure how to approach solving this issue.

[thick socket]

yeah...however the class itself doesn't need to be a MonoBehavior as long as the time method is being used by a class inside of a MonoBehavior's Update right

[simple egret]

Either get a Dictionary<FacingDirection, Vector2> and fill it manually, or make a utility method that converts the enum to a vector. Extension method is also possible!

// In STATIC class
public static Vector2 AsVector2(this FacingDirection dir) => dir switch
{
    FacingDirection.North => Vector2.up,
    // etc.
}

Usage:
Vector2 v = FacingDirection.North.AsVector2();

[rain minnow]

Yep. You can use UnityEngine code in regular c# as long as you have the correct using directive . . .

[leaden ice]

I'd do this:

public static class FacingDirectionExtensions {
  static Dictionary<FacingDirection, Vector2> dirMap = new() {
    {FacingDirection.North, Vector2.up},
    {FacingDirection.NorthEast, (Vector2.up + Vector2.right).normalized},
    // etc...
  }

  public static Vector2 ToDir(this FacingDirection dir) {
    return dirMap[dir];
  }
}```

ah sorry i was slow

very similar to SPR2's

[simple egret]

Mix of both, not sure which is more performant

[leaden ice]

they're probably similar. I think the switch becomes a jump table at some point

[simple egret]

Yeah it has 8 cases so probably becomes a jump table

[thick socket]

I feel like Im doing this a bad way...

public class MyMeleeWeapon : MonoBehaviour
{
    public string shooterTag = "";
    [SerializeField] Fighter fighter;
    private void OnTriggerEnter2D(Collider2D collision)
    {
        var tag = collision.transform.tag;
        if ((tag == "Fighter" || tag == "Player") && tag != shooterTag)
        {
            Fighter colFighter = collision.GetComponent<Fighter>();
            colFighter.Damage(fighter.stats.attackDmg);
        }
    }
}```

Is there a better way to be doing this?

[simple sable]

Oh, thank you so much guys! That's very helpful.

becomes a jump table
What does that mean (if you don't mind answering)?

[thick socket]

essentially Im wanting to grab the fighters dmg and objects tag(to make sure its not colliding/dmging itself)

but the Top Fighter(Grim Reaper) will need to grab this script(to enable/disable dmg) and this script will need to grab the Fighter script to work

secondary question...when I dont want the script to do dmg...should I just disable the collider trigger, or set a bool in the script to not do dmg?

It's in the produced "machine code" C# compiles to. It's an optimized way of moving the execution to a different instruction, so it will probably:

1. convert the enum value to a number from 0 to 7 (one per direction)
2. use that number to move the execution to [the current line + the number representing the enum value]
3. create the vector on the instruction it falls on
4. return it
   It's like the dictionary, but a low-level representation of it, known when the compiler goes over your C# code

[simple sable]

So.. is it like a hashtable?

[simple egret]

Yep, but made in the IL code C# compiles to

[wispy depot]

I feel like im probably very dumb here but its telling me that hit might not be initialized and wont let me compile.

RaycastHit hit;
var ray = Camera.main.ScreenPointToRay(Input.mousePosition);

if (Physics.Raycast(ray, hit))
{
    if (hit.transform.gameObject.GetComponent<Planet>() != null)
    {
        selectedPlanet = hit.transform.gameObject;
    }
}

[simple egret]

Initialize variable inline: if (Physics.Raycast(ray, out RaycastHit hit))

You'll then immediately see where you're trying to access it where it's not available

[simple sable]

That's very detailed, thank you for the explanation!

[wispy depot]

oh thanks!

[simple egret]

Made the test on an online compiler, it indeed does a jump table because there are enough enum values.
For input code (image 1), produces a jump table switch IL instruction (image 2) and all its corresponding cases where it loads the numbers (instructions the arrows point to, ldc.i4.* - "load integer number")

(the last cases are cropped but it goes on below)

i've began to refactor my enemy movement code into using a state pattern, but running into an issue. My previous logic for patrolling was to create a coroutine that travels in some direction, waits X seconds, and then travels in another way, but apparently i can't use a coroutine in a class that doesn't inherit from monobehaviour. What's a good way to remedy this

[rigid island]

make the routine start from a monobehvaior

[urban lintel]

i do have a statemanager (monobehaviour) that has references to the states, should i just add a function inside statemanager that allows for creation/termination of coroutines and call that from inside the states?

[simple sable]

I'm gonna be honest, that is stuff I never heard of. So it's a little bit hard for me to understand.

But I guess performance is never an issue in my case, right?

[rigid island]

iirc you only need monobehavior to start from a mono, but the IEnumerator can be in a reg class

[urban lintel]

i tried doing just stateManager.StartCoroutine but got this after

actually this might be unrelated, lemme read some more lol

[simple egret]

Yeah in this case you don't need to worry about it. Look for more expensive stuff like repeated Find() and GetComponent<T>() calls in frequently executed code like in Update

[rigid island]

whats on line 39

[urban lintel]

ok yeah nvm fixed it, doing stateManager.StartCoroutine works fine 👍

[rigid island]

Greetings. I'm in a 2D gamejam.

I've been fighting this bug for the whole jam.

I have a sprite moving down.

There is a sprite below it with a boxcollider2d.

They are on the same layer.

They are siblings.

This raycast2d is happening in a coroutine.

But, the racast2d never hits anything.

foreach (Transform sprite in currentSprites)
{
    Debug.Log(sprite);
    RaycastHit2D hit = Physics2D.Raycast(sprite.position, new Vector2(sprite.position.x, sprite.position.y - 1), 10f, 8, 9f, 10f);
    if (hit.collider != null && !currentSprites.Contains(hit.collider.transform))
    {
        Debug.Log("Hit Collider.");
        audioSource.Play();
        StartCoroutine(MiniGameResolved());
        yield break;
    }

}

[leaden ice]

Why are you passing in 8 as a layer mask?

That's almost certainly wrong

[kind cipher]

that is the layer index of the layer they are on

[leaden ice]

right so it's definitely wrong

because that parameter needs a layer mask

not a layer index

[kind cipher]

oh! right!

[leaden ice]

The easiest way to deal with layer masks is:

public LayerMask myMask;```

[kind cipher]

🤦

[leaden ice]

define it in the inspector

[thick socket]

I did the exact same thing 😄

What you did makes sense to me lol

But Unity says no

[rigid island]

Using magic numbers is also frowned on :l

[fair wadi]

Hello! I was trying to commit my project to github but recived the above error, one person said this was because of the fact that I did not have a .gitingore file, yet I have one in my github

[simple egret]

But do you have the gitignore locally?

It won't do anything until it's aside your Assets folder on your filesystem

It's configured a special way, so it needs to be at your Unity project root - looks like it is the case here, at least on the remote repository

[fair wadi]

how can I know if it is local, sorry I am kinda new to this

[simple egret]

You'll see it on your computer as a file, using your file explorer

[fair wadi]

like this?

[simple egret]

Yes

Can you show hidden folders? Seems like something is missing here

Display > Hidden Elements check box at the top

There should be your Git root (a folder named .git) along these

Like this

Not sure why the C# solution and project files don't appear either on your side

[fair wadi]

I showed hidden items but nothing changed

[simple egret]

I wonder where your Git root is, then, maybe one folder above?

[fair wadi]

like that?

[leaden ice]

Based on this image the root is in the fodler that contains the project and some other folder

[leaden ice]

yeah looks like you put your git root one level higher than it should be

[fair wadi]

okay, so move that folder into the FBLA one?

[leaden ice]

i would delete it

and do git init inside the project

idk what the FBLA folder is

[fair wadi]

could I just move it

[leaden ice]

or how it's relevant here

[fair wadi]

The FBLA folder is where my game is locaed

[leaden ice]

no your game is located in "My project"

or rather

this might be two different projects

[fair wadi]

Yeah I think it is in the FBLA folder

[leaden ice]

yeah this is definitely multiple projects

[fair wadi]

yeah... so what sould I do?

[leaden ice]

for simplicity I recommend only having one project per git repository

[fair wadi]

Yeah okay I think I messed that up

okay so I deleted the "My Project"

[simple egret]

Now you can pull the whole contents of FBLA onto the git root one folder above

[fair wadi]

okay

[simple egret]

The gitignore should now be at the same level as the .git folder, and Git will pick up a lot of "moved element" changes

And ignore the useless stuff like the Library folder, hopefully

Do note that once you commit and push your changes to GitHub, the "My Project" folder there will also be deleted!

[fair wadi]

so like this?

Yeah there is nothing really in there so it is fine

[simple egret]

What, no look at the screenshot I posted

[fair wadi]

so what did I do wrong

[simple egret]

You moved the folder into the git folder

[fair wadi]

Yeah

Oh I see

[simple egret]

Move the contents of FBLA 2023-2024 Unity into Documents/Github/FBLA-2023-2024/

[fair wadi]

Okay

then can I delete the FBLA folder?

[simple egret]

It'll be empty, so yep

[fair wadi]

okay

So like this

[simple egret]

The first 5 files indicate you're still in the .git folder

[leaden ice]

yeah you've really messed something up lol

you shouldn't be poking around inside .git typically

[simple egret]

Should be like this ^^^
Project folders along .git

[heady iris]

I'm deciding how I'm going to name states for different state machines. I have two choices:

• Make every class name unique. LocomotionIdleState, for example
• Use the same names, then use namespaces. IdleState in the namespace MyGame.States.Locomotion, for example

The second one seems nice, but then the component's name in the inspector is just IdleState.

Perhaps I need an editor extension that displays the namespace?

I am also concerned about not being able to immediately tell what kind of state something is, though. I'd just have IdleState in the code with a using MyGame.States.Locomotion up top.

MyGame.States.Locomotion.IdleState would be a bit too much, lol

[fair wadi]

Okay I think I see now

Like this?

[heady iris]

This is how it should be laid out, yes.

The folder you're currently in is the root directory. It contains the hidden .git folder, the .gitignore file, and then whatever folders or files are part of your project.

Also, is this in OneDrive or something? You've got that "Status" column.

you'll have a lot of churn from all the .git files being backed up, and if you have more than one device, modifying the files elsewhere would cause Surprise Changes

i don't think Git would appreciate that

[fair wadi]

Okay I finally GIT it now thank you!

[heady iris]

btw, you can put a .gitignore wherever you want in the project

it affects the folder it's in (and any children of it)

i haven't actually used that in practice yet, but it could make things simpler if you have weird requirements

[tired rock]

public IEnumerator Roll()
{
Physics2D.IgnoreCollision(GameObject.FindWithTag("EnnemyHit").GetComponent<Collider2D>(), Collide, true);
canRoll = false;
canbehit = false;

    Vector2 rollDirection = new Vector2(xMovement, yMovement).normalized;

    rb.velocity = rollDirection * rollSpeed;

    yield return new WaitForSeconds(rollDuration);
    Physics2D.IgnoreCollision(GameObject.FindWithTag("EnnemyHit").GetComponent<Collider2D>(), Collide, false);
    
    rb.velocity = Vector2.zero;
    canbehit = true;

    yield return new WaitForSeconds(rollCooldown);
    canRoll = true;
}

The roll Dont ignore Any of the EnnemyHit Tagged Object , may someone help me please ?

Physics2D.IgnoreCollision will ignore collisions between a single pair of colliders

[tired rock]

Oh , Is there an alternative ?

[heady iris]

I'd put all of the enemies on an Enemy layer, and put the player on a Player layer

then you can use https://docs.unity3d.com/ScriptReference/Physics2D.IgnoreLayerCollision.html to ignore collisions between two entire layers

Physics2D.IgnoreLayerCollision(LayerMask.NameToLayer("Player"), LayerMask.NameToLayer("Enemy"), true);

note that I used LayerMask.NameToLayer, not LayerMask.GetMask. GetMask is not used here.

[tired rock]

Oh : Thanks !

[heady iris]

https://docs.unity3d.com/Manual/LayerBasedCollision.html

note that you will want to look at the Physics 2D settings if you need to turn collisions on or off between layers

[kind cipher]

Thanks again for your help. Everything is now working as I intended now!

[heady iris]

but in this case, you probably want both the player and enemy layers to collide with everything else

(so that you don't fall through the floor)

[tired rock]

Yes haha

Dont want it to fall into backrooms

Thanks , it works as intended !

[undone mesa]

Hi guys! I have a simple problem but I can't seem to find the error... I have a script attached to a Canvas object but when I try to access the varaible containing a Slider, I can't seem to do it.

Here my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

using System;

public class UIMenu : MonoBehaviour
{
    public Button getBack;
    public Slider slider1;
    public Slider slider2;
    // Start is called before the first frame update
    void Start()
    {
        Button button = getBack.GetComponent<Button>();
        button.onClick.AddListener(PlayGame);
    }

    private void PlayGame()
    {
        PlayerPrefs.SetInt("sensitivity", Mathf.FloorToInt(slider2.value));
        PlayerPrefs.SetInt("levels", Mathf.FloorToInt(slider1.value));
        SceneManager.LoadScene("Game");
    }
}

UI Menu on Unity photo: https://discord-cdn.is-terrible.com/6f29EzbPP

[knotty sun]

wdym 'can't seem to do it'?

[undone mesa]

Ohh sorry, i forgot to share the error 😅

Unity prints out this error: https://discord-cdn.is-terrible.com/6f2baGDkv

[simple egret]

Side note, you don't need the GetComponent in Start. Your field is already of Button type.

[undone mesa]

Oh thanks!

[knotty sun]

Are you sure you dont have 2 UIMenu scripts enabled?

[simple egret]

And as for the error, since your screenshot here shows that all fields are assigned, my guess is that you have another UIMenu script elsewhere that doesn't have the fields assigned, and that's the one throwing the exception

Search for any other using the Hierarchy search bar: t: UIMenu, as well as in prefabs if you're instantiating these in

[heady iris]

clicking the error might take you to the offending object

[undone mesa]

Yep! That was it. Thanks a lot guys! ❤️

[trail ferry]

Is there a way to enable/disable a component in a script (not at runtime level but during editor)

[knotty sun]

it's exactly the same code

[trail ferry]

Uhh, but monobehaviours only work at runtime, right?

[knotty sun]

no

I suspect you are looking for the ExecuteInEditMode attribute

[trail ferry]

yes, thank you

[heady iris]

or [ExecuteAlways], to make it work in prefab mode as well

[scarlet viper]

am i doint this incorrectly?

        float speed = 0.005f;
        float t = Mathf.InverseLerp(from, to, ring.localPosition.y);
        smoooooth = Mathf.SmoothStep(from, to, t);
        float smoothSpeed = speed * smoooooth;

basically here smooooth variable is equal to ring.localposition.y

and theres no smoothing

Does the t parameter go from 0.0 to 1.0 ?

[spring creek]

Yes. 1 being equal to the second parameter, and 0 being equal to the first in lerp

[scarlet viper]

but im not sure what im doing wrong. in other script i did a test from 0 to 1 and it works there

        if (isWorking)
        {
            var pos = transform.position;

            pos.y = Mathf.SmoothStep(0f, 1f, t += 0.001f);

            var ss = (pos - cachedPosition).magnitude;
            Debug.Log(ss);
            transform.position = pos;
            cachedPosition = transform.position;
        }

[thick socket]

aka your top code works but the code you just posted doesn't?

[scarlet viper]

the top code doesnt work but the code i posted now does

[mellow sigil]

I don't really understand what you're trying to do in the first snippet

[torpid sand]

GPT seems to know shit tons of Unity. The other day I asked it to create scripts so that I can make custom tracks on the timeline and it provided almost out of the box. And timeline is very badly covered when googling

[mellow sigil]

t is expected to increase linearly, but you're inserting the object position which does not change linearly

just increment t like you do in the second snippet

[thick socket]

yeah its pretty nice sometimes, I used to for making 2 enemies track each other to always look at each other in 2d

unity does that great in 3d but its 2d doesn't exist

[torpid sand]

You mean it doesn't know Unity's 2d "helper" functions?

Like LookAt in 3d etc

[latent latch]

I find it decent for shader stuff but that's less specific to unity

[torpid sand]

So far I haven't had a topic where it wouldn't be at least somewhat useful

And always so friendly too

[scarlet viper]

ahh i see, my issue was

i was multiplying speed by smoothstep value
so even if it smoothed ends, the speed was going to be bigger every time near the max value

[cold willow]

For reference this is the script I will be talking about https://pastebin.com/PMp6HMd5

In that script you will notice the functions for Log In, Sign Up, Reset Password, and a few others. Those functions you don't have to worry about they just are functions for telling a service I use called loot locker to sign in players into their accounts. At the top of the page I am declaring variables for tmp input fields that are used to specify the emails and passwords for the sign in and login functions. Then under that I have 3 functions that get called on update that take the input fields .text and set it equal to a string that is used to log in and sign up. Upon testing this in my game on desktop, it works just fine and normal. Upon testing this on webgl, I am able to type in the input fields and everything but upon clicking the log in button, I am told that the email was never specified. Meaning that the email variable for logging in was just nothing even though that variable as getting set to the .text value of the input fields. It may be more than just the email if may also be the password, not sure. Any idea why this could be happening?

[gray mural]

What method is called when player exists the game? (also when I exit it in unity using play button)

[cold willow]

void OnApplicationQuit()
{
Debug.Log("Application ending after " + Time.time + " seconds");
}

[gray mural]

forgot to mention that it doesn't work for me

it doesn't print anything

[cold willow]

What platform are you on?

[gray mural]

Windows

[cold willow]

Are you building to windows?

[gray mural]

yes, "Windows, Max, Linux"

actually I have forgot to save changes is VS, OnApplicationQuit works now 😅

thank you 😄

[cold willow]

Lol, it happens to everyone. Glad you found your issue!

[torpid sand]

That's the hardest thing to debug remotely; you've done everything right but you haven't saved your files...

[thick socket]

nah I was saying that LookAt in 3d works great but not in 2d 😄

[torpid sand]

Well... Yeah

[thick socket]

more like I would have expected if they had a lookat 3d function they might have one for 2d

[torpid sand]

Hehe

You could ask GPT to provide you with the math on how to rotate a 2d object's axis to point towards a point within Unity context

[thick socket]

thats what I was trying to say that I did 😄

[torpid sand]

Hmm okay 🙂 I'm a little lost but no worry

Did you pay respects to me?

(isn't that what F stands for...)

[heady iris]

i would not consult a spam machine

[heady iris]

what is the matter?

[torpid sand]

lol

[heady iris]

are you having problems with it behaving weirdly when looking at something close to the up-vector?

[torpid sand]

Why not utilize a tool that provides really good starting points and tips for almost anything you do

[heady iris]

because it will emit plausible-looking garbage that just confuses and misleads someone who doesn't know how to spot it

LLMs generate plausible text, not correct text

[torpid sand]

So do developers

[heady iris]

yes, which is why I prefer to not add more spam to my plate

also, see #📖┃code-of-conduct .

[somber nacelle]

and what do you plan to do if the plausible text is just outright wrong but looks correct?

"i learned wrong on purpose!"

[heady iris]

asking or answering questions based on unverified AI-generated content is not allowed (for this reason)

[torpid sand]

You modify it to your needs and use it as if it was entirely written by yourself

[torpid sand]

Well, I don't think we did either here today

[somber nacelle]

ah so you still use the wrong information. lmao

[torpid sand]

Why would it be "wrong" information if you get the tips and/or examples you were looking for that you can use to speed up your development?

Obviously you shouldn't ask it to provide you with the full code for you game

[heady iris]

it is a tautology: if you know enough to fix AI-generated spam, you didn't need the AI-generated spam

[torpid sand]

You're very black and white about the topic

[somber nacelle]

because very often it just produces text that is outright incorrect. and you have to already have experience in the topic you are asking it about to actually spot that

[heady iris]

end of story. don't tell someone to "go ask GPT"

[torpid sand]

Have you even tried to use it to your purposes?

[spring creek]

I third the idea the chatgpt is terrible for making scripts beyond just doing some boilerplate you're too lazy to physically write yourself, but DO know exactly HOW to write. We spend a LOT of time helping people dig out of the hole chatgpt dug them into.

[torpid sand]

I mean if that topic is not accepted on the server as discussion, then sure I'll shut up

[heady iris]

i've tried to FIX a large amount of garbage code

only to be told that, surprise, it's garbage because ChatGPT spewed it out

[somber nacelle]

last time i decided to use it the information it provided to me was incorrect so i had to go and do it myself which was something i wanted to avoid at the time which is why i used it in the first place
and it's not like i asked it something difficult. it was a fairly simple math problem

[thick socket]

not necessarily, its nice for explaining what code does most of the time, giving and helping correct math functions and telling you which function might do what you want

[heady iris]

The code looks plausible, but then it's just nonsense that doesn't do anything

[spring creek]

I've used it dozens of times. Each time was just... useless. It would have been faster to google it. and yes, that includes 4.

It LOOKS fine, and might work superficially. And that is the danger

[torpid sand]

Alright. Well I'm not new to coding and I've utilized GPT's help tens of times and every single time it has been a help to some extent. So I'll just keep on doing that and you can keep on not doing it.

[heady iris]

just learn to read and search documentation. you'll get what you need.

[somber nacelle]

and how many times was it wrong? or can you not tell when it is wrong because, as you said, you are new to coding?

[heady iris]

it is an unending tide of spam and i'm tired of it

[torpid sand]

Did I say I'm new to coding?

[heady iris]

well, you're espousing the gospel of AI spam, so...

[gray mural]

usually it's much faster to ask ai, than using a browser (assuming you know how to ask questions correctly)

[somber nacelle]

somehow slipped right past the "not" in that sentence. my bad. now imagine if i were an AI and just ignored that. that's what you're getting when using spam generation tools

[torpid sand]

Well, there's no need to discuss this any further. I'll just keep on doing that and you can keep on not doing it.

[thick socket]

from my experience...its almost always wrong

however it typically gets you close enough to just need a few tweaks

[gray mural]

well, of course it won't be great if you just say "write me code to do smth" and copy paste it in your ide

[thick socket]

saving me a lot of time when using functions I haven't done much with before

[somber nacelle]

if ya'll wanna go and "ask questions correctly" you can keep that somewhere else. AI generated answers are not permitted here and it's a shit response to just go "go ask chat gpt" in response to someone's question

[torpid sand]

I don't think anyone said that in response to someone's question

[spring creek]

I scrolled up to find it, and in the process of linking it, hawk deleted it lmfao
It said it was good for math

[somber nacelle]

this you #archived-code-general message

[gray mural]

neither do I think I have answered or asked questions using ai

[thick socket]

I can neither confirm nor deny this 😄

[torpid sand]

Well yeah but I gave the actual thing to ask. And it was used as an example. I don't think HawkAngel was having any issue, we were just talking about the subject in general

[heady iris]

you can set transform.right or transform.up to make a transform face a certain direction

this works correctly in 2D

e.g. transform.right = target.position - transform.position;

[cold willow]

For reference this is the script I will be talking about https://pastebin.com/PMp6HMd5

In that script you will notice the functions for Log In, Sign Up, Reset Password, and a few others. Those functions you don't have to worry about they just are functions for telling a service I use called loot locker to sign in players into their accounts. At the top of the page I am declaring variables for tmp input fields that are used to specify the emails and passwords for the sign in and login functions.

Meaning that the email variable for logging in was just nothing even though that variable as getting set to the .text value of the input fields. It may be more than just the email if may also be the password, not sure. Any idea why this could be happening?

[somber nacelle]

I'm curious why you need the Update method at all. just grab the content of those input fields when you need to log in. and make sure you're checking that they aren't empty or null using string.IsNullOrWhitespace

[cold willow]

I had that aswell. I changed my login parameters to just take the .text value of the tmp input field and got the same error.

I even tried directly setting it the value of the input field, I dont think this is an error with loot locker because it works just fine with other platforms.

[somber nacelle]

okay and what debugging steps have you taken?

also keep in mind that in your Start method you're calling LogIn whether playerprefs has those keys or not. you also don't bother doing any handling for when your variables are null, you still attempt to log in instead of throwing an error or logging useful info

and since 90% of the variables in this class are public, that means anything can change them

[heady iris]

calling LogIn from Start also means that the code in Update hasn't run yet, which will mean the text input fields never got read

that seems weird.

[somber nacelle]

the entire setup is pretty weird tbh. but calling LogIn from Start appears to assume that they have saved credentials in PlayerPrefs (which is also not a great idea)

[heady iris]

"polling" like that gives you room for inconsistencies

it can get really bad if there are several steps involved (possibly across several objects)

imagine if A sets B and B sets C and C sets D

you could get up to three frames of latency depending on execution order

[gleaming vessel]

Hi everyone. Trying to make communication between game and website. I make a webGL build and give it to guy who makes a call to my game from website. However, it doesn't call current function and I can't understand why. I can send info from Game, but can't get it. Here is example of code in JS and my code in Unity

[thick socket]

if (_currentVelocity.x > 0.2f || _currentVelocity.x < 0.2f)
        {
            character.SetState(CharacterState.Run);
            Debug.Log(_currentVelocity + "X Current Velocity");
        }

(0.00, 0.00, 0.00)X Current Velocity is what debugs....how!??!

[somber nacelle]

is 0 less than 0.2?

[thick socket]

gosh darnit

where did my - sign go

thanks 😄

[somber nacelle]

just use Mathf.Abs and you don't need to check against both

[gleaming vessel]

I tried using this method but the result is the same. I can't even understand where the error is, from my side or from the site side. How can I check this?

[primal wind]

https://docs.unity3d.com/2021.3/Documentation/ScriptReference/Application.ExternalCall.html this apparently is obsolete

They do give this as an alternative https://docs.unity3d.com/2021.3/Documentation/Manual/webgl-interactingwithbrowserscripting.html

[cinder fractal]

hi i have a script and a shader that makes my gameobject highlight when needed but when i turn on the shader all gameobjects with this shader material highlight how do i make it so i can choose which gameobjects highlight with one material?

[leaden solstice]

Renderer.material is easiest way to copy material. Also you might want to consider batch-able solutions such as MaterialPropertyBlock

[cinder fractal]

Thanks! But if i have 2 materials on a gameobject how do i specify that i want the second one?

[hollow fjord]

anyone know if it is possible to set these values via script?

[delicate zinc]

Given a bounds struct, how could i use said bound's values to check if a collider is inside it?

[leaden ice]

Sure https://docs.unity3d.com/ScriptReference/Animations.ParentConstraint-rotationAxis.html
https://docs.unity3d.com/ScriptReference/Animations.ParentConstraint-translationAxis.html

[hollow fjord]

thx

[leaden ice]

Since a bounds is a box you can use Physics.OverlapBox and check if the collider is in it.

[delicate zinc]

hm, idk but i asume i'm supposed to use bounds.Extent for overlap box's half extents?

or just bounds.size?

[leaden ice]

Use the properties from the bounds to make an equivalent box for overlap box.

[delicate zinc]

guh

[leaden ice]

I'll leave that as an exercise for you to figure out because I'm not at my computer

Shouldn't be hard to figure out

Just read the docs

[delicate zinc]

fair enough i guess lol

[leaden ice]

Sorry to make you actually do a little work? 😐

[delicate zinc]

its not that, sorry i came out as rude

i wouldnt be here if i didnt check the documentation

or online

i couldnt find a good way to use the bounds struct for an overlap box

just a bit frustrated, sorry

[scarlet viper]

Can I somehow create a speed variable for **Vector3.MoveTowards **with Mathf.SmoothStep instead of Vector3.Distance?
Is there a mathematical Trick that could do this?

        float distance = Vector3.Distance(ring.localPosition, new Vector3(0f, targetLocal.y < average ? from : to, 0f));

        ring.localPosition = targetLocal.y > ring.localPosition.y
            ? targetLocal
            : Vector3.MoveTowards(ring.localPosition, targetLocal, 3f * distance * Time.deltaTime);

Distance works fine but its too irregular (too fast at first and too slow at the end)

SmoothStep is mostly the same speed with slower ends, so a preferable solution
But SmoothStep gives value in range between 2 values, lets say between 0 and 1
Im not sure how to create speed out of it.

[delicate zinc]

Ok so, i'm working on a dungeon generation system for my thesis, it's been painful so far (as any procedural generation system). but i've found myself with an issue i dont precisely know how to deal with.)

My system is currently following the idea of using prefabs, the prefab hierarchy has at it's root aRoom component. this Room component contains mainly 2 things:
1.- An array of Door components, to know the entryways to the room
2.- A Bounds struct, which is calculated from the child colliders.

My main issue right now has to do with rotating an instantiated Room so it has the "correct" orientation. On the picture below there are two rooms, the first room (the taller bounding box) and the second room (the one that's shaped as a plus). it may not look like it but the rightmost door is the connection between both rooms i'm trying to make. i know i can use transform.RotateAround on the Room's transform, using the Door's position as the pivot. the issue is, i have no ideda how to properly calculate the angle needed so the room goes from the first picture, to the second picture.

[leaden solstice]

Use something like Lerp(s, e, SmoothStep(0, 1, t))

Or consider SmoothDamp?

[halcyon venture]

can someone help me, i have a sprite for a wood plank (2d game), and i want to resize it to be the floor of my game, however i dont want to stretch it out, i want to repeat it until its the correct size, the first image is the one that i want to change to be repeated to make it look like the second image

[scarlet viper]

I think smoothdamp is even better than smoothing at the ends

thanks a lot man

[deep oyster]

Is it possible to get a list of all currently pressed buttons?

[heady iris]

as in, buttons on the keyboard?

not UI buttons

[deep oyster]

I'd like to print out a list of buttons the user is currently pressing on their keyboard in a debug window

[heady iris]

I don't think you can ask for buttons that are being actively pressed. You could, however, iterate over all of the KeyCode enum values

[deep oyster]

Ooooh

[heady iris]

        foreach (KeyCode code in Enum.GetValues(typeof(KeyCode)))
        {

        }

Enum is from the System namespace

note that you have to write KeyCode, not just var or something

[deep oyster]

Can I toString the keycode value?

so I can print "Shift" or whatever

[heady iris]

        System.Enum.GetName(typeof(KeyCode), KeyCode.A);

ToString might also work

[deep oyster]

Thanks!

[heady iris]

huh, GetValues returns...Array

never knew that

[deep oyster]

[heady iris]

this will generate some garbage, since it's making an array every time

but that's probably a non-issue for showing some text in a debug menu

[deep oyster]

hm

guess just put var values = Enum.GetValues and then foreach in values?

[heady iris]

You could calculate it once and just keep it, yeah

[heady iris]

just making a local variable wouldn't do anything, since you'd still be computing it every frame

it's a really minor thing

[deep oyster]

oh make it a class thing then

[heady iris]

but I guess it would be nice to do something like:

private List<KeyCode> keyCodes = new();

void Awake() {
  foreach (KeyCode code in System.Enum.GetValues(typeof(KeyCode)))
    keyCodes.Add(code);
 }

[deep oyster]

do editor windows call awake when they first appear

also is there a controller input equivalent of keycodes

buttoncodes or smth

[heady iris]

yeah, see the "messages" section of the docs https://docs.unity3d.com/ScriptReference/EditorWindow.html

[delicate zinc]

god i feel like i'm going insane with this dungeongen stuff

[heady iris]

not that I'm aware of; you would have to query GetButton for various buttons defined in the Input Manager

You're using the old input system, I presume?

If you're using the new one, then you could just iterate over every map in your input action asset, then iterate over every action in every map

[deep oyster]

I don't have any input system right now I'm just messing around with debug windows

so now I can see every keyboard input I'm getting and I wondered if I could do the same with a gamepad

[heady iris]

the old input system uses stuff like Input.GetKeyDown

so that's what you're using

[deep oyster]

Oh, yeah

GetKey tho cause I don't want it to just last one frame

[hoary mason]

I don't quite get this, why does the box's position still go to into decimals?

    private void FixedUpdate()
    {
        Hit = Physics2D.Raycast((Vector2)transform.position, Movement, 0.5f, LayerMask.GetMask("Object"));
        if (Hit)
        {
            Stop(Hit.collider.gameObject);
        }
        if (Moving)
        {
            Control.MovePosition((Vector2)transform.position + Movement * spe * Time.deltaTime);
        }
    }
    private void Stop(GameObject collision)
    {
        Moving = false;
        Movement = new Vector2(0.0f, 0.0f);
            if (Mathf.Abs(collision.transform.position.x - transform.position.x) <= Movement.x)
            {
                transform.position = new Vector2((int)collision.transform.position.x - (int)Movement.x,transform.position.y);
            }
            else if(Mathf.Abs(collision.transform.position.y - transform.position.y) <= Movement.y)
            {
                transform.position = new Vector2((int)transform.position.x, collision.transform.position.y - (int)Movement.y);

            }
    }
}

the gameobjects it's colliding with's positions are on integers

[heady iris]

is this an object with a Rigidbody2D on it?

if so, it will still have a velocity and drift off after getting reposiitoned

[hoary mason]

It is kinematic

Either way, fixed it anyway by just changing the conditionals to "if Movement x ==0" for one and movement y for the otehr

Seems like it wasn't reading the conditionals well

Hi, does anyone know a good library to decode gif files at runtime ? I would like to be able to download one from a server and use it as a texture, or in a RawImage

[ivory crescent]

Has anyone implemented custom richtext tags in TMP? I cant find anything usefull in my search and just want to know if someone here has done it or has resources to it.

[swift falcon]

Hi, some questions about compute shader
I have a list of vertices that form a 2D loop and I want to iteratively relax the loop like this

1. Calculate the displacement of every vertex based on the coord of its previous and next vertex
2. Apply the displacement to every vertex
3. Repeat 1 and 2 for a certain number of iterations
   I'm wondering if this is something achievable with a computer shader, I'm mostly confused about how to do multiple iterations of the displacement process in a shader

something like this:

void Relaxation(int iter){
    borderPos and forces are Vector2 arrays with equal but undetermined lengths
    int loopCount = borderPos.Count;
    for (int iter = 0; iter < 100; iter++){
        for (int i = 0; i < loopCount; i++){
            forces[i] = calculations with borderPos[i], borderPos[i-1] and borderPos[i+1];
        }
        for (int i = 0; i < loopCount; i++){
            borderPos[i] += forces[i];
        }
    }
}

[cosmic rain]

Shaders are applicable when there's a huge number of data that needs one specific processing applied to each data element in parallel.
If the processing is sequential or dependent on the results of processing for other elements in the collection, shaders wouldn't work.

Now, I don't know what kind of calc you need to do, but from the pseudocode it's implied that the calculations are in sequence, so each on would depend on the previous one.

Then, there's the issue with the iterations. You'd need to make several dispatches for each iteration, which is probably gonna introduce quite a lot of overhead.
Perhaps with command buffers you can just run each iteration in sequence without getting the data back to the CPU, but that's pretty advanced and I'm not sure if that's possible.

I don't know how fast you need it to be, but maybe try implementing it as a job first and see if it's good enough.

[heady verge]

need Help with

Collider = Trigger,
Event System is here,
but if i enter with my mouse, nothing is happaning.
Any Idea ?
( Collider is insde the Hips of a Charakter, do select him ).

the Collider is just a simple Cube, downscaled, with a trigger collider.
Do not work.

[polar umbra]

This was the tutorial I was watching https://youtu.be/b0AQg5ZTpac?si=JCFTYY3RY3Hc0t_V

[knotty sun]

So look at 11:32

one for @naive swallow

[polar umbra]

which lines?

[knotty sun]

OMG. What she is typing at that moment

[polar umbra]

yeah my code is exactly the same if (Vector3.Distance (transform.position, destination) > 0.1f)

[knotty sun]

no

mb 11:20

[polar umbra]

got that too Vector3.MoveTowards(transform.position, destination, movementSpeed * Time.deltaTime);

[knotty sun]

look again, this time carefully

[polar umbra]

Wow I can't believe I missed that

[scarlet viper]

I noticed people often treat magnitude as speed is this correct?

if (rigidbody.velocity.magnitude > maxSpeed)

wouldnt local velocity's Z be more accurate?

[dusk apex]

The magnitude would be the range of the vector. Sort of like the hypotenuse of some x and y coordinate.

Speed and velocity being the same, it would just evaluate the three component float value into a single usable value

[cosmic rain]

An object doesn't have to be moving along it's Z axis to have velocity(and consequently speed). It could be moving sideways or any other direction.

[real anvil]

Velocity is speed + direction

Magnitude can be considered speed in this case

As you don't care about direction

(also use square magnitude to avoid an unnecessary sqrt operation)

[dusk apex]

Make sure to square your max speed value, if so.

• I'm working with audio source and need to detect the moment when the clip comes to an end, even after being paused, modified by pitch/effect/time etc.. It's been quite a challenge but luckily audio source has a .time property and its compression-agnostic counterpart, .timeSamples, which can be compared to those of the clip. So far it has been working good, but recently i figured out that not always the end is registered. It turns out that sometimes the source's .time and .timeSamples will become 0 without reaching the values of .clip.length and .clip.samples respectively, thus never metting the equality condition in my code. Why is it and how should i work around this?

• An example that i currently have catched:
  .clip.samples - 65664
.timeSamples in the previous frame - 64915
.timeSamples in this frame - 0

• Hence the line under if (_source.timeSamples >= _source.clip.samples) is never executed (in this particular case)

[leaden ice]

The audio system runs on a separate thread so it's very likely Update will not coincide with the final audio sample.

[radiant shadow]

guys, why is null is not recommended using with unity objects? there is a reason?

[leaden ice]

yes, it's because it doesn't respect Unity's overloaded == operator which checks for destroyed objects

i.e. this https://github.com/Unity-Technologies/UnityCsReference/blob/0e55b91bc34b1d385a5785cd3d9e2246098e2d37/Runtime/Export/Scripting/UnityEngineObject.bindings.cs#L506

[proud hare]

That is for GameObjects only right? Things dervied from MonoBehaviour still need "== null" to check?

[leaden ice]

no

it's not for GameObjects

it's for EVERYTHING that derives from UnityEngine.Object

including MonoBehaviours, ScriptableObjects, all Unity asset types, etc..

[proud hare]

Oh weird, I got an error the other day because I had
if( myComponent ) {
blah blah
}

And I got an error saying that myComponent couldn't be compared as a bool or something like that. Maybe I misread the error.

(I'm just testing it right now...)

[knotty sun]

C# is not C++

[heady iris]

then myComponent's type was not derived from UnityEngine.Object

[leaden ice]

There is an implicit conversion to bool operator for UnityEngine.Object as well, so it WILL work assuming myComponent was a MonoBehaviour or something:
https://github.com/Unity-Technologies/UnityCsReference/blob/0e55b91bc34b1d385a5785cd3d9e2246098e2d37/Runtime/Export/Scripting/UnityEngineObject.bindings.cs#L115

you probably misinterpreted the error

[heady iris]

(or you had another error)

[gleaming vessel]

@primal wind Hi! I tried to make communication with website like it, but now I have error when I want to build webGL project

[proud hare]

..yeh I just tested it, and just as you said ,it works without the ==null

I thought it was odd when I got the error, but I must have been mistaken about what I reading. Probably wasn't a MonoBehaviour class or something like that.

[knotty sun]

so Hello is in your jslib?

[gleaming vessel]

I can't even build it to test it on website

[knotty sun]

do you have a jslib?

[gleaming vessel]

no

[knotty sun]

there you go, what do you think you are talking to?

[thick socket]

public class Fighter : MonoBehaviour
{
    protected virtual void Awake()
    {
        // Base class Awake logic here
        Debug.Log("0");
    }
}
public class Enemy : Fighter
{
    protected override void Awake()
    {
        base.Awake(); // Call the base class's Awake method
        // Additional logic for Enemy
        Debug.Log("1");
    }
}
public class Enemy2 : Enemy
{
    protected override void Awake()
    {
        base.Awake(); // Call the base class's Awake method (from Enemy)
        // Additional logic for Enemy2
        Debug.Log("2");
    }
}

would Enemy2 Debug 0 1 2

or just 0 2

not sure if it will take Enemy base also or just Fighter base

[knotty sun]

should be 0,1,2

[thick socket]

Is there a way to take only Fighters base and not Enemy base as Enemy2?

[knotty sun]

you could build in a type check in Enemy Awake

[thick socket]

like just a bool?

[knotty sun]

after base.Awake in Enemy
if (this is Enemy2) return

[thick socket]

gotcha, I assume thats just setting a protected bool basically?

[knotty sun]

no, not really, it's checking which class it actually is

[thick socket]

oh thats the actual code

didn't see that coming

[knotty sun]

yes

[thick socket]

so if I had just
if (this is Enemy) do xyz

that wouldn't execute as Enemy2 right

[knotty sun]

yes

[thick socket]

😄

[knotty sun]

because Enemy2 is Enemy2, Enemy and Fighter

[thick socket]

gotcha

[proud hare]

If my priority was readablity and not performance. I might go with a generic enemy, and then put extra components on for the ways in which the enemies differ.

So, if I have a generic enemy, and an enemy that makes a beep noise. I'd just add a MakeABeepingNoise component onto the generic enemy.

As I said though, that's not prioritising performance ( or memory usage ) but in some situations ( such as wanting game designers to assemble these different enemies within the Unity Editor ) then it can have benefits.

[thick socket]

gotcha, my main enemy using a "Character" script

however a different type of enemy has a "Monster" script

so I need some way to switch things up without also breaking my state machine that uses Enemy 😄

[knotty sun]

@thick socket if you want to catch all classes that derive from Enemy you could do

if (this.GetType().baseType == typeof(Enemy)) ...

[proud hare]

There's also a pattern where you can have a StateMachine.cs. , that defines the state machine itself, like the names of states and what can transition to what.

And then you can put the conditional checks, and the actions themselves in another component, on the same GameObject.

Again, you'd need a specific use case for this to be a good solution, and you'd need to be sure your performance wasn't going to suffer as a result. But it can be an interesting pattern because you can even then reuses StateMachines across entities, but the behaviours are further specialised by the additional component.

[mellow zinc]

    {
        if (Physics.Raycast(transform.position, Vector3.down, out slopeHit, playerHeight * 0.5f + 0.3f))
        {
            float angle = Vector3.Angle(Vector3.up, slopeHit.normal);
            return angle < maxSlopeAngle && angle != 0;
        }
    }``` why doesnt this work

it says that not all code paths return a value

[knotty sun]

exactly, you do not have a return if the if fails

[proud hare]

just add return false before the last }

[mellow zinc]

what

Oh

okay

thanks

[proud hare]

Also, what do you think of:
return (angle < maxSlopeAngle) && (angle != 0);

I know you know what the line meant anway, but what if someone else less experienced sees it, or you from the future see it when you are feeling sleepy 🙂

[knotty sun]

actually I think that is wrong is should be a single &

[thick socket]

yeah I'll just add 1 extra perameter to my base Fighter that only Monsters use 😄

[proud hare]

No should be &&

but you need != 0f right?
Or can you just use 0 without the f?

[thick socket]

in if statements you use 2

[knotty sun]

you only need the f when decimals are specified to differentiate from a double

[proud hare]

If you use a single & then it will do a logical AND on every bit in the representation, but seing as it is a float, I think that would be essentially meaningless.

Actually, maybe Unity will stop you from even using & with a float?

[knotty sun]

but not in this case I suspect he wants to always evaluate both conditions hence the single &

[proud hare]

Oh, thanks for clarifying that.

[thick socket]

interesting

[simple spire]

Hello guys, I have a navmesh with agents on a 2D tilemap. Everythings fine, but when I want to add a nav mesh obstacle to my agents, they falls like if there was a x80 gravity :/ do you know why ?

[heady iris]

wouldn't that mean the agent is being pushed away from itself?

if it has an obstacle on itself

[simple spire]

that was I thinked yes, but how can I do for counting my agent like an obstacle on my navmesh ?

[gleaming vessel]

Sorry, if I was rude. English is not my native language. I understood that I should have jslib file in Unity and now it works, but I don't understand how to communicate with FronEnd developer to get info about a player with my jslib file

here is a code

[swift falcon]

Why would he always want to evaluate the second condition?

[simple spire]

when I do research on internet or unity manual it was the only solution I saw, but I'm agree with you I think he push himself

[heady iris]

What are you trying to do?

[knotty sun]

becuase he is checking for a < and a !=

[simple spire]

having agent who avoid others agents in theyre paths

[swift falcon]

And?

[heady iris]

agents can already avoid bumping into each other

[swift falcon]

If the first one is false, the whole thing will be false, no matter what the second condition is @knotty sun

so no need to check both

[knotty sun]

so he wants to know if it is < a figure and != 0. a && will stop if the < is true

[simple spire]

on my game right now they collapse each others

I will try to search why

[swift falcon]

No it won't

[heady iris]

you have that backwards

it will stop if the left hand side is false, not true

and since a != 0 has no side effects, it never matters whether you short-circuit or not

[knotty sun]

true, mb

[gleaming vessel]

@knotty sun

[knotty sun]

you just write javascript, you can access anything in the webpage js that happens to be running

[thick socket]

Why can't I put my Monster Script inside the "Monster" Enemy Character Script

and also why can't I enable/disable the Monster Script?

[heady iris]

Second question: if you don't have Awake/Start/Update/etc. methods, you won't get a checkbox

because disabling the behaviour would do literally nothing

[thick socket]

public class Monster : MonoBehaviour
    {
        public SpriteRenderer Head;
        public List<Sprite> HeadSprites;
        public Animator Animator;
        public bool Variations;
        public event Action<string> OnEvent = eventName => { };
        
        /// <summary>
        /// Called on Awake.
        /// </summary>
        public void Awake()
        {
            if (Variations)
            {
                var variations = GetComponents<MonsterVariation>();
                var random = UnityEngine.Random.Range(0, variations.Length + 1);

                if (random > 0)
                {
                    variations[random - 1].Apply();
                }
            }```

when I try to drag it in it gives me the little "icon" that means "sure you can put that here" but then it just doesn't let me

(hoping its just a unity bug so restarting Unity rn)
still bugged after restart

[heady iris]

perhaps you have two scripts named Monster?

Recent versions of Unity allow you to have a script whose name doesn't match the class name

[somber nacelle]

note that Awake is not affected by the enabled state of the monobehaviour itself but rather the active state of the gameobject. so the checkbox does not appear for just that method

[heady iris]

I just checked; it does appear

[somber nacelle]

what version are you on? because newer versions have the checkbox no matter what

[heady iris]

oh wait, wrong.

[thick socket]

2022.1.23f1

[heady iris]

I got punked by saving at the wrong moment. you are correct.

Good to know that! I actually didn't know it ignored the enabled state.

[thick socket]

Every script I've wrote has a checkbox and works nicely
