I like my slop so i know who to blame 😇

This is moreso a question about vscode's workspace and how it handle new files
when I try creating a new file Project\Scripts\myScript.cs through vscode's file explorer, it does not get automatically added to the workspace or the Assembly-CSharp.csproj, and I have to manually modify and add that new file
Is there something I can do to make files get automically added?

It's probably recommending a collection initializer

rancid tinsel
#

so it doesn't throw an error or warning

#

Hover over the mixer group counts or the add method.

#

e.g. MixerGroupCounts[soundEmitter.SoundData.mixerGroup = [soundEmitter];

maybe it's signalling that I can simplify this?

wintry quarry

yes that's my point

about the collection initialiazer

rancid tinsel
#

ah ok

wintry quarry
#

try hovering over different parts of the line

rancid tinsel
#

doesn't say anything

#

as in it just shows what the thing is like in the screenshot above

Try Ctrl + . on the line

I have a prefab called FloatingMenuIcon which has a has the following script attached to its primary object :
⁨⁨```
public class FloatingMenuIcon : MonoBehaviour
{
public Image image;
}

In another class I have a property:
⁨⁨```
        private FloatingMenuIcon iconOpen;
```⁩⁩
which I populate via :
⁨⁨```
iconOpen = Instantiate(iconPrefab, iconPanel.transform);
```⁩⁩
Can someone confirm. The actual way to make this prefab active/inactive is via:
⁨⁨```
iconOpen.gameObject.SetActive(false);
```⁩⁩
Just feels a little wierd and I want to make sure I'm not missing something. Thanks

Hide the icon from the player

#

Or show it

#

The icon is a UI element

cosmic dagger
#

is that what you want to happen?

low copper
#

Yes, but I want to ensure I am doing it correctly

cosmic dagger
#

oh, so it doesn't actually de/activate when testing?

#

by the way, SetActive activates and deactivates the GameObject. it's different from just hiding or showing the ui element . . .

#

deactivating and activating a GameObject will stop all of its scripts from running Update and every component is disabled . . .

low copper
#

Everything seems to be working fine. I'm just suprised I am using .gameObject.....I'm new to all of this

cosmic dagger
#

.gameObject will access the GameObject the FloatingMenuIcon script is attached to . . .

wintry quarry
cosmic dagger
#

if you only want to show or hide the graphic, you can use a CanvasGroup component or disable the Image.enabled property (from the Image component) as well . . .

I have a class Node : IInteractable and imlpements OnInteract();
Would this be a suitable to call the function (regardless of which class implements IInteractable)
The code does not function and I would like insight on why this fails to run (The function just Debug.Log("Interacted with" + this.name)
naive pawn
#

ok so sounds like 2 separate questions

#

the latter, debug to see where the flow of code reaches

rocky canyon
# slow blaze ```C# void Interact() { RaycastHit hit; interactionRay.o...

im using the same style system for my interactables..

  • IInteractable interface
  • Raycasts
  • and TryGet

debug like guy mentioned ^.. find out and make sure that each step of the code is running how it should. that will help u sniff out whats wrong.. i just had an incident where i culdnt get the Interact button press to work w/ the raycast but finally i found out I had it set to have to hold it .5 a second b4 the input system throws the event..

gizmo's help too.. but most likely the raycast is working as usual but something else is wrong.

image.png image.png
#

ofc i cache my interactable the entire time im looking at it..
so then when i press interact i just call its .Interact() method from the cached

oh i meant to point out im using the ⁨TryGetComponent(out XXx xxx)⁩ signatur

naive pawn
rocky canyon

well, (minus this part) is wht i mean..

not sur what the specific terminolgy for it * is

it's the same signature, you're just letting it be inferred

How do I implement gyroscope/phone-tilting controls with the new input system?
I for some reason cannot understand how to actually get it to work:
What type of binding do I add in the Input Actions Editor? Why for some bindings I can choose Angular Velocity [Gyroscope], and for some not? How do I access the values later down in C# code?

#

I know this issue is easy to fix - but I'm to frustrated or tunnel-visioned to fix it by myself. Any help will be dearly appreciated.

not code per se but is anyone else having extremely slow github clones today? normally it takes no longer than 3 seconds, but today its taking 10s of minutes

#

I thought it might be my AV or internet but I turned AV off, and internet is currently fine

naive pawn
#

i think it had issues like last night or something

#

says it doesn't have any right now though

rancid tinsel
#

weird

#

also it was super slow earlier for like 50% and then the rest it zoomed like normal in a second

naive pawn
#

may just be an isolated issue with some specific cluster or something like that

Starting game dev here. I want to create some games, but i'm unsure of what audience would be best. Can you tell me what types of games and on what plaform is most popular now?

you should probably focus on learning first before thinking of optimal markets and genres

#

different gamers will like different things, all genres have an audience, it's not like there's going to be one genre that 80% of all "gamers" hyperfixate on

cosmic quail
solar hill
#

if youre trying to optimize your game for a certain audience youre sort of setting yourself up for failure in the long run

#

consider that the markets for popular genres are highly contested

#

if success is what drives you, youre better off doing something unique

naive pawn
#

a quick google seems to suggest the most popular genre has <20% market share

arctic island
naive pawn
#

that'll basically just have the same answer lol

#

plenty of people still play on pc though.

prime goblet
#

pc is quite popular because of steam, console is more expensive though for publishing

#

but if you don’t have any games what are ya gonna publish lol

#

additionally, you’ll likely want to make some kind of advertising or get your game out there so that no matter where you publish, people will actually know your game exists

#

you’ll find players on every platform for every genre, so it’s really your call

what if something doesn't work and you have no idea how and why, are some tutorials are out dated?

solar hill

you can probably start by asking here.

naive pawn
#

are some tutorials are out dated?
yes, because time doesn't stop flowing

slender nymph
#

9 times out of 10 it's user error when it comes to code related stuff though

naive pawn
#

unless it's a tutorial from before 6.1 and you're on >6.1 and the error is the input setting

slender nymph
#

even that's still kind of user error since the error tells you what to do to fix it

yeah but technically the root cause isn't your fault

ah so i need to change the name in the code?

slender nymph
#

yes, you already do see the component in the dropdown menu, you're just not recognizing the name because you've confused the file name for the component/class name

ah ok i see thank you verry much

sorry it is my first time trying to build a game and thougt this woul be a good place to learn

i'd recommend learning the basics of c# outside the context of unity first. that will make learning unity easier because you'll already understand how the code is structured so you'll really just need to learn what the unity types do

Can someone explain to me why this causes a nullreferenceexception when used? (The UpdateProfileList/ClearProfile method)

#

If I add them regularly one by one with createnewprofileinmenu, it works fine, but if I destroy (reload the menu) it causes a nullreference exception on the first profile listener

You may want to provide the full error (preferably the entire console window) so we can validate the problem.

texts[1].text = profile.CompletedLevelsCount.ToString() + "/4";

polar acorn
#

texts, texts[1], profile, or profile.CompletedLevelsCount

#

One of those is null

#

Use logs or the debugger to find out which one

ivory bobcat
#

The idea is to understand the immediate problem (the source of the nre - likely some variable or collection) and then further figure out why it's null

cloud agate
#

ok, just thought it was the Button line because that's where it landed before. No idea why it lands here now

polar acorn
#

See what's null

#

then you can work on why's null

cloud agate
#

thank you eitherway

ivory bobcat
#

It isn't a difficult problem to solve so I hope you've successfully resolved the issue

cloud agate
#

I think I might have figured the issue

#

I made profile entries that might be wrong but are still on the json where I get them from

Yeah that's it

just asking if someone knows why this dictionary refuses to take in any values? i keep getting an "Argument Exception: Value does not fall within the expected range." for line 38, and any attempt to print the keys/values doesn't output anything. i've found similar issues online with delegates/dictionaries but couldn't find one exactly like this. the delegate signature matches the stored function signature exactly, i'm pretty sure.

public class Move {

    public int handCond;
    public delegate void MoveFunc();
    public MoveFunc moveFunc1;
    public MoveFunc moveFunc2;

    public Move(int handCond, MoveFunc moveFunc) {
        this.handCond = handCond;
        this.moveFunc1 = moveFunc;
    }

    public Move(int handCond, MoveFunc moveFunc1, MoveFunc moveFunc2) {
        this.handCond = handCond;
        this.moveFunc1 = moveFunc1;
        this.moveFunc2 = moveFunc2;
    }
}

public class punching : MonoBehaviour

    public Sprite palm;

    public static handScript LFist; // line 28

It says it's in start, if the line they're saying is line 38 it'd be that line

or was that line omitted?

then somehow its the conversion to the delegate type?

naive pawn
#

do stacktraces not usually contain some internal unity code

wintry quarry

Its normal to start from where unity first invoked it (from native)

polar acorn

#

i just did the drag and drop thing once they showed up in inspector

grand snow
#

wait they are fuckin null

polar acorn
#

but where do you assign them

naive pawn
#

wth, does null.Method yield that instead of a NRE?

wintry quarry
#

hmmm possibly yeah

polar acorn
#

Where do you tell the code which handScripts the variables RFist and LFist hold?

wintry quarry
tender crane
#

DUDE

#

youre so right

grand snow
wintry quarry
#

that is definitely a weird error message

naive pawn
grand snow
#

TIL

wintry quarry
#

Probably the reference.Method delegates to some internal method which throws ArgumentException if the reference is null

#

that's super unintuitive

tender crane
wintry quarry

thank you all so much!!

if it were, eg, () => RFist.Punch() it'd be an NRE wouldn't it (but it'd only have the error once it was called)

A question how to approach my issue the correct/smart way:

I have an item interaciton script where I listen for if my item has dialog and if it has, I want to play the dialog first and when the dialog ends I want to activate my item. What's the best way to approach this? I don't think it's correct o change anything in my dialogue maanager right?

image.png image.png
fickle stump
wintry quarry
#

is this running in Update or something?

#

!code

radiant voidBOT
wintry quarry
#

How do I tell the game/script to 'wait' here

But in general it sounds like what you want is a coroutine. Coroutines are designed to do exactly this

swift crag
#

notably, you cannot "pause" the Update function

#

this would freeze the game

fickle stump
#

I thought of something like a Coroutine, but as far as I've used it, it's mainly to pause something for x amount of seconds and not for 'wait until the dialog ended'

wintry quarry
#

Or WaitWhile

#

Or just yield return null in a loop and checking a condition manually

fickle stump
#

Interessting. This way I can make yield return !dialogue.playing basically

sour fulcrum
#

just mentioning cuz it trips people up sometimes

fickle stump
#

yeah I've been struggling with stuff like that unfortunately. Still learning stuff like that

#

very helpfull guys, thanks a bunch ❤️

wintry quarry
#

It's called a lambda if you want to look it up.

fickle stump
#

So, what I'd like to know now is, what do the brackets mean?

#

we basically give in nothing and then we wait until the state reaches its goal?

swift crag
#

() => 1 is a function that takes no arguments and returns 1

#

() => frame >= 10 is a function that takes no arguments and tells you if frame is at least 10

#

It captures the frame variable and retains a reference to it.

#

You could also write a method like this

# 
bool PrincessRescued() {
  return frame >= 10;
}
#

and then do yield return new WaitUntil(PrincessRescued);

#

Unity will evaluate that function every frame until it returns true

#

anonymous functions are convenient for one-off functions that don't need a name

swift crag
#

we would say that it's a member of the class or struct

#

just as fields are

#

public int x = 123;

#

fields are member variables; methods are member functions

fickle stump
#

Woah that's a lot of infos

#

That's so interessting, but I feel like I'm not there yet to fully understand everything you said. But I'm sure I'll get there

swift crag
#

the important part here is that you're creating a function that tells you if you're done

# 
public void Example() {
  System.Action<bool> isDone = () => frame >= 10;
  frame = 5;
  isDone(); // returns false
  frame = 15;
  isDone(); // returns true
}
fickle stump
#

As of now I understood the wait that I'm able to use coroutines and also can check if a variable changes its value
And thats a win in my books 😄

sour fulcrum
#

ya you dont need to know too much of all that just yet

fickle stump
swift crag
#

But if frame was going up by 1 in each Update loop, then yeah

fickle stump
#

oh yeah that totally makes sense

swift crag
#

Coroutines allow you to suspend a method and come back to it later

fickle stump
#

thanks for explaining 😄

swift crag
#

so you could be checking if a certain number of frames have gone by

Hi i have a small question a made a game and now i want to ad a second level to my game. i did this by making a new scene adding a floor and copying the player from level 1 to level 2 but the movement doesnt seem to work even tho it has the same script. am i doing somthing wrong?

so first of all when i hit the start button nothing seems to really heapen the screen doesnt pop up of the game starting, second is that when i hit the buttons to move the player doesnt move. and this all works in the first level. + in het debug nothing is showing that could be a problem to the movement

you have to do debugging to see where it's going wrong

#

For a 2d game is disabling game objects when out of view and enabling them when back in view sufficient enough for proper optimization if I have alot of game objects? (I am unsure on how much disabling Game Objects lightens pc workload)

naive pawn

quite an impossible question to answer

naive pawn
strange gate
#

Honestly just thinking about the future, currently my game isnt that far for me to have performance issues yet, but I will need to be able to be able to use it on old laptops as well. Also Id say at most around 100-200 game objects could be on the screen

naive pawn
#

that's quite small, relatively

#

unless you have a loop of 1000s of iterations in each gameobject, you probably won't have issues

#

don't optimize prematurely

#

you're just wasting your effort

#

if you have issues (or you suspect potential issues), figure out what is actually the culprit with a profiler, rather than just doing stuff and hope it's better

#

reactivating gameobjects does have a cost ie if you need to reawaken every rigidbody and add every collider back into the physics scene

What do you mean by "multiple times" here? If you are going to read every frame, definitely bad. Is there a reason not to make a save & load system which reads the file once at start and holds the data in a class for the duration of the game or something similar? The file would be written to once when the player saves the game or leaves depending which you want. When the game is running, the save system (class or similar) is the way to get the data and modify it and from there the data can be saved later. Preferably the save system should keep track if anything has changed since overwriting a file when nothing has changed can be wasteful

Can anybody tell me why?

I'm trying to add cooldown and the general timer works, but the enemy throws the object no matter what the cool down is at.
the cool down can be at any number, and it will still throw it -- ignoring the check completely.

keen dew
#

Put Debug.Log("Cooldown timer: " + throwCooldownTimer); inside the brackets and see what it prints

wintry quarry
earnest raven
wintry quarry
#

Of course it's help

#

What did you try

#

Simply logging the values of all those variables in the if condition will tell you everything you need to know

earnest raven
#

I literally watched the cooldown in realtime as it was 5 and then went back up as if nothing happened

#

hi guys can someone help me with this. Im trying to get the 3d obj picked up, but it doesnt seem to work. Can someone help me pls im a beginner in this

Use a debugger or logs

earnest raven
#

okay what's the difference from watching everything happen as it goes and debugging

#

I did use logs

solar hill
radiant voidBOT
solar hill
#

please send your code correctly, nobody wants to download your .cs files in order to help you

wintry quarry
solar hill
#

also you have 2 more conditionals there, not just the timer, have you verified they are also being set correctly?

earnest raven
#

I put logs to check:
If THAT specific if() was happening (it was)
If the cooldown was above 0 when it happened (it was)

wintry quarry
earnest raven
#

Ikr. Let me set it up as it was

wintry quarry
#

You need to put a log inside the if and print the current value of each of those variables

earnest raven
#

i know

#

That's what I did

wintry quarry
#

well show us 😉

earnest raven
wintry quarry
#

theres no labels

earnest raven
#

no what

wintry quarry
#

Try this:

Debug.Log($"Entered the if statement. Timer is: {throwCooldownTimer}");```
#

and then run the game and show us what prints

earnest raven
#

what's the difference?

wintry quarry
#

it's just more informative. When you do Debug.Log(throwCooldownTimer); it's easy to mix that log up with another one since it's just a contextless number

earnest raven
#

It's the only Log printed I don't feel like there's any need

#
  • I've kept an eye on the timer in the inspector as well and even when it was above 0 it still threw the object
wintry quarry
#

It's very rare in my experience to only have one log printing in my code

earnest raven
#

It's the only thing I need right now as it's the only enemy

wintry quarry
#

regardless

#

can you run it

#

and tell us what it prints

#

or show us a screenshot of the console

wintry quarry
#

that's why logging or the debugger are the most reliable methods of debugging

earnest raven
#

I wasn't looking at the wrong variable??? it literally changed in real time

wintry quarry
#

Can you just run it and show us the console

#

this arguing isn't helping anyone

earnest raven
#

yeah jesus christ dude have patience

#

i didn't have Unity open

wintry quarry
#

I just guarantee you there's no way this is going to print a number larger than 0

naive pawn
solar hill
earnest raven
#

He waited for the cooldown once, but then it completely ignored the cooldown afterwards.

image.png
wintry quarry
#

So the timer is always below 0

naive pawn
#

it didn't change either

wintry quarry
#

Seems like you're not actually resetting it

earnest raven
#

I am

wintry quarry
#

So your variable here and whatever else you're looking at are not in sync

wintry quarry
#

!code

radiant voidBOT
naive pawn
wintry quarry
#

but the log confirms it's not a problem with this if statement

#

the problem is elsewhere

earnest raven
#

It plays the animation and an Animation event calls "ThrowCog" which should reset the cooldown near the end

image.png
wintry quarry
#

!code

radiant voidBOT
wintry quarry
#

these little snippets don't have enough context to know what's wrong

earnest raven
#

Why? this is the main focus

solar hill
#

why are you making it difficult to help you

wintry quarry
#

Do you want help or not? I'm telling you this isn't enough information. Why are you fighting us lol

#

There is no way for us to even confirm this code is running.

naive pawn
#

i feel like the value not changing between those 2 logs is a solid hint

#

but that hint is worthless without more context on where and how the value is being changed

wintry quarry
#

Yes it makes it very clear the value is not being reset

#

In fact that log printed 600 times

#

So there were 600 "throws" happening

naive pawn
#

for all we know you might be modifying throwCooldown instead shrugsinjapanese

wintry quarry
#

yeah we haven't even seen how the timer is implemented

keep a copy in memory to batch your saves, probably

#

no constant reading/writing to disk

wintry quarry
tender mirage
wintry quarry
#

caching is usually the word for an intermediate, faster form of storage between your application and the main storage system.

#

I'm just talking about the actual live version of the in-memory game data

tender mirage
#

Ah. So you’re refering to just modifying the variable that gets exported and not actually export it then.

wintry quarry
#

yes

#

and when we say "variable" here I'm talking about a class you specially constructed to hold your game data that needs to be saved

tender mirage
#

Still gotta learn what limitations constructors have compared to classes.

wintry quarry
#

they're not... comparable things

#

Unless you mean structs?

tender mirage
#

My bad. Yeah i was refering to structs.

And not the new instance with parameters

#

Constructors allow

naive pawn
#

...what?

#

classes and structs can both have constructors if that's what you're saying?

tender mirage
#

No. That wasn’t what this was about

#

Just a miss understanding on my part about mixing structs and constructors.

swift crag
#

the names do overlap :p

#

"struct" is short for "structure"

#

the name comes from C

tender mirage
#

Really? C had it?

naive pawn
#

yeah

swift crag
#

C#'s structs closely match the behavior of C structs

naive pawn
#

c++ also had classes (but the distinction isn't the same as c# struct vs class)

#

you could use either one as either a value or a ref/pointer type in c/c++

swift crag
#

if you have a struct-type variable, you are literally holding the struct's contents

#

rather than a class-type variable, where you're merely holding a reference to an object

swift crag
#

C++ requires you to allocate an object on the heap and then store a pointer to it to get behavior similar to C# classes

naive pawn
tender mirage
#

Wait. But c# doesn’t allow type references on structs, right? Also thanks for reminding me that structs are called structs and not constructs because i would’ve probably typed in construct next time that i used it

swift crag
naive pawn
#

what do you mean by "type references"

swift crag
#

Perhaps you're thinking of something else, yeah

tender mirage
#

Maybe i am. I should probably learn it.

swift crag
#

I wonder if you're thinking of this behavior

naive pawn
#

("type reference" isn't a term used in c#)

wintry quarry
#

if that's what you mean

#

a variable for a class is a reference to an instance of the class.

tender mirage
wintry quarry
#

A variable for a struct contains the actual data of the struct

naive pawn
#

given that boxing can be done on mutable types in c# unlike java or js

wintry quarry
#

Not really, no. You can't have two ifferent boxed references to the same struct

naive pawn
#

i'm referring to getting a boxed reference and then passing that around

wintry quarry
#

How would that look in practice?

naive pawn
#

yeah i'm just starting to work out the details in my head and it doesn't work lmao

swift crag
#

I mean, you can absolutely take a ref to a variable containing a struct

image.png
wintry quarry
#

yeah ref variables

swift crag
#

(the collision between "reference type" and "ref" is really annoying)

wintry quarry
#

anyway.... let's not complicate things haha

swift crag
#

ref struct time

#

💥

swift crag
swift crag
tender mirage
naive pawn
swift crag
naive pawn
#

yeah (that's a reference type)

swift crag
#

at one point I had read most of the C++ standard and could give an extremely pedantic answer about this

#

but i may have forgor

swift crag
#

classes get allocated on the heap and have to be cleaned up by the garbage collector

#

for example, Vector3 is a struct

naive pawn
#

conceptually,
class - some object or entity
struct - some bundle of data

tender mirage
#

If they’re a single instance. Doesn’t that mean you can just easily reference them from a another script?

naive pawn
#

you mean a singleton?

#

what do you mean by "they" in "if they're a single instance"

#

you're using a lot of vague pronouns

tender mirage
#

Well. You can have multiple structs. Can’t you just reference them all directly by name and get their variables?

wintry quarry
naive pawn
elfin pike
naive pawn
# 
Vector3 a = new Vector3(1, 2, 3);
Debug.Log(a.x);

I made static class for storing and taking from storage file, but I have to keep taken data to use it until player doesn't needs it.

tender mirage
# wintry quarry Show a code example of what you mean 
//Struct
public struct MyStruct 
{

    public int myStructVariable = 1;

}


//From a monobehavior script
public MyStruct myStruct;

private void Start()
{


    myStruct.myStructVariable = 1;

    //I was thinking of this but it doesn't work
    MyStruct.myStructVariable = 1;


}
swift crag
#

MyStruct is the actual type.

#

types are like a blueprint: they describe the shape of something

#

myStruct is a variable that contains a MyStruct

#

it's an object created from the blueprint

#

myStructVariable is a field – a variable that is a member of an object

#

you must have a specific instance of MyStruct to do anything with that field

naive pawn
wintry quarry
#

Yes

tender mirage
#

Yeah thanks for the clarification. I have had some exceptions to this rule where referencing the type was the way to go. I thought it was also the case with here

for instance having a public constant requires you to referencing the name of the class rather then a instance

wintry quarry
#

I think using a class is the better way to go by default you will run into fewer pitfalls

tender mirage
#

I see. Yeah i just use classes for now.

wintry quarry
#

You just need to remember to construct the instance with new()

naive pawn
#

anything else is

#

classes and structs arent' different in this regard at all

tender mirage
naive pawn
# wintry quarry How would that look in practice?

oh it does actually work

using System;

public class HelloWorld {
    public static void Main(string[] args) {
        I s = new S() { a = 0 };
        I t = s;
        t.a = 1;
        Console.WriteLine(s.a);
    }
}

interface I { int a { get; set; } }
struct S : I { public int a { get; set; } }

# worldly mural then whats the benefit of using serializefield? couldnt i just use a public floa...

You could make everything public but you shouldn't. Generally only the things that you need to access from outside the class itself should be public. The only, but noteworthy, real problem with things being public unnecessarily is how it can allow you to access things that are not meant to be accessed which can cause bugs in your code. [SerializeField] on private field is the better choice when you only want to make the field editeable from the inspector

You should do the tutorial with a compatible unity version to not have to worry about Unity api integration.

the only major thing is old input being depricated

#

Is there a way to turn on safe mode compilation without being in safe mode? This prevents race conditions from multiple agents while the other one can crash

grand snow
#

agents? huh?

#

safe mode is purely to let you fix compile errors before fully loading a project where assets could get mutated incorrectly

red hull

red hull
# teal viper Why would they crash? Or is it unity crashing? Anyways, having 3 different agent...

Its either an infite loop or crash with crashreport. Its as I said probably a race condition. you want to review what one agent did, while another one is still writing. While, as I said, a solution would be git worktrees, I noticed that the safemode doesnt seem to have that problem. I sometimes like to work on a single branch on a single module but different section of it in parallel to avoid git merges since they know this way more about each other. The job system that uses burst compile (which can be turned on to compile ahead of time in the editor.... I should uncheck it) is more fragile to it.
So thats why I asked the orignial question if I can have always save mode somehow.

Edit: Maybe its just burst compile, I have burstified everything gonna test so nvm

teal viper
#

I just asked what exactly crashes, because initially it sounded like the agents crash, and not unity.
I only expected an answer like "unity crashes". That's it. Nothing more, nothing less..

Can somebody explain, why are we using singleton instead of static class?

naive pawn
#

they're for different things

#

are you referring to some specific example?

#

we aren't psychic

sour fulcrum
#

instances are for when you want instances

in minecraft if theres a dungeon it might spawn 3 zombies

#

you'd want 3 instances of the zombie

#

most things in games you'd want instances

elfin pike
sour fulcrum
#

two big reasons that come up

  1. being able to mess with serialized/exposed fields in the editor (so it needs to be a component on a gameobject)
  2. need a monobehaviour if you want to run coroutines
#

a lot of my stuff in singleton setups ends up being static

Hi, sorry to bother you, but I have a question. I started using the Localization asset at the beginning of this week, but for the past two days, whenever I reopen the project, half of the things I had done in the Tables are not saved. Do you have any idea why? Just to clarify, I’m not in Play Mode while working and I save continuously.

#

If it's not, you should probably try moving the question to an appropriate channel or #💻┃unity-talk
Make sure to provide pictures and examples to illustrate what's happening and what is expected to happen.

wide wolf
# ivory bobcat Is this directly related to coding?

I think so, because I created a script that extracts the text inside the TMPs to then create the key, and I think it might be related — the only thing is that before I close the project, everything works fine…
If you think this isn’t related to coding anyway, I’ll move the chat right away, and thank you in advance.

alright, do some debugging then - is the rotation code reached? what value you are setting?

also, you should not read back the value of transform.eulerAngles, you should track that value yourself

2: No notes just apply what you listen to with an editor
3: both
4: neither (something else)

#

it probably varies based on the person, but what do you guys recommend

swift crag
#

I try to avoid triginometry in general, haha

naive pawn
swift crag
#

Vector3 has some very useful methods

#

Quaternion, too

naive pawn
#

try them out and see what works for you

swift crag
#

Quaternion.AngleAxis(dir, Vector3.up); spits out a rotation that points in the direction of dir

naive pawn
#

oh that definitely would help yeah

swift crag
#

Vector3.SignedAngle tells you the angle between two vectors

#

(given a third vector to figure out whether it's a positive or negative rotation)

naive pawn
#

(though Atan2 in particular is a very conceptually simple operation imo)

swift crag
#

yeah, I just haven't had to use it in ages

dusty pendant
#

the euler thing isnt workin g

#

i want it to rotate to move direction only...

naive pawn
#

are the values for _targetRotation correct?

dusty pendant
#

ill see

dusty pendant
naive pawn
#

well, are those the angles you expect?

dusty pendant
#

ye

#

man i started to hate unity

swift crag
#

I wonder if you're rotating the wrong object

dusty pendant
swift crag
#

This is going to rotate the object that the script is attached to

dusty pendant
#

its attached to player, aand i dont see any rotation

swift crag
#

Disable the script and manually rotate the player

#

(in Play mode -- not in Edit mode)

#

does the player rotate as expected?

#

Also, is there an Animator involved? If so, show me your hierarchy

#

(and even if there isn't, do that anyway)

#

I'm wondering if you are trying to rotate an object with a SkinnedMeshRenderer on it

dusty pendant
swift crag
dusty pendant
swift crag
#

Okay, that should be fine.

swift crag
#

When you're getting weird behavior, you want to start ruling things out

dusty pendant
swift crag
#

Okay, so something else is rotating the player

#

I don't think animators can affect their own object's position

dusty pendant
#

it was working fine before... all i did was remove jump functions and this bug came

swift crag
#

oh, they totally can

swift crag
dusty pendant
#

i also removed jump functions

swift crag
#

hm, that doesn't sound like the cause

swift crag
#

Turn off the Animator as well.

#

really, just keep turning things off until you can rotate the player object properly

dusty pendant
#

ill try

swift crag
#

oh, okay, so you can freely rotate the player while the component is disabled?

dusty pendant
#

not game mode

#

when i enable it and try to rotate manually, it doesnt rotate

swift crag
#

by "enable it", do you mean going into play mode?

dusty pendant
#

no

#

enable script

#

it snaps asap

swift crag
#

i'm guessing the script has [ExecuteAlways] or [ExecuteInEditMode] at the top, then

dusty pendant
#

no

swift crag
#

and you are not in Play Mode?

image.png
dusty pendant
swift crag
#

okay, that's expected behavior

#

This means that no other script is trying to rotate the player

#

Make sure that you aren't setting the player's rotation anywhere else in the third person controller script

dusty pendant
#

no way

#

i disabled all transform.rotation and it still snaps lol

#

i have 2 transf rotation idk why that

swift crag
#

note that you could also be setting transform.forward

#

(or up/right)

#

if you can't find anything, share your whole script with one of these sites

dusty pendant
#

i enabled this and its useless

transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(inputDirection), RotationSmoothTime);
swift crag
#

naive pawn
#

does this object or the parent have an RB or CC?

worldly mural
naive pawn
#

you shouldn't be modifying its transform then - the rb will try to control the transform

use the rb to rotate

okay, ill try that out, thanks!

for unity coding, would you pretty much only use float, int, string, bool, List<T>
or are things like double, decimal, char also sometimes needed

#

for variables

hexed terrace
#

yes, you use what's needed for the thing being done

frail hawk

it depends on what you need

swift crag

higher-precision data types (like double) should be used if your game requires the precision

Programming is a great way to learn English though since everything will be in English. My English was much worse than yours when I started learning Unity. Watching a lot of Unity videos and tutorials, reading discussions and documentations online and conversing in help servers like this one pretty much got me where I am now with my English skills. Don't be afraid to ask anything you need help with. Most here aren't native in English either, perfection isn't required to be understood. Good luck

hi everyone, quick question
i'm working on a basic dialogue system for my games lobby area, and it is fully working; but when i rotate the npc the direction of the text gets all messed up (first npc in the video is with 0 rotation, second one is rotated 180)

for context, i use individual gameobjects for each letter, so that i can have them scale up, and drop down
i spawn them in, inside a foreach loop that goes through all the char's of my dialogue string

GameObject temp = Instantiate(dialogueLetter, letterStartPos.position + (letterStartPos.right * (letterX * letterScale)) - new Vector3(0, lineDistance * letterY, 0), letterStartPos.rotation);

i use the right direction of the start position, as a reference, and the right direction points in the correct direction in the editor, if i check it with local editing, so i have no idea why it's moving the incorrect direction

would love some help cus i'm completely lost

but if you rotate 180 it kinda makes sense its flipped cause your right of enemy may not be your right of cam

twilit jolt
# rich adder anything helps, where exactly does the startPos end up when you rotate npc, do y...

the start position is parented inside a worldspace canvas, that is under the camera, and the camera is under the root of the npc, so it's right direction shouldn't change (and when running the game and checking the scene view, the right direction is still pointing where it should be pointing)

i parent the letters under the startpos after they are done being set up, but that shouldn't change anything since by then they are already positioned (i also already tried positioning them after the SetParent, the result was the same)

also here is the full foreach that does the spawning (the ''star" is what i use as a new line marker, cus it's easier than doing multy char samplings for \n)

foreach(char c in dialogue.dialogueText){
    PlayAudioChar(dialogue.dialogueTextAudio[iter]);
    iter++;

    if(c == 'star'){
        letterX = 0;
        letterY++;
    }else{
        GameObject temp = Instantiate(dialogueLetter, (letterStartPos.position + (letterStartPos.right * (letterX * letterScale))) - new Vector3(0, lineDistance * letterY, 0), letterStartPos.rotation);
        temp.transform.SetParent(letterStartPos, false);
        lettersGen.Add(temp.GetComponent<DialogueLetter>().SetMeUp(c));
        
        letterX++;
        if(letterX >= lettersPerLine){
            letterX = 0;
            letterY++;
        }
    }

    yield return new WaitForSeconds(timeBetweenChars);
}

(ignore the star thingie, it broke the code display so i replaced the star char with the word)

okay, so i tried doing some tests to see if maybe i can find something, and it seems like the directions of the transform get fully inverted
i tried offsetting the letters using the .forward instead, and they move backwards not forwards (again, this only happens when i rotate the setup)

i have a component for the letters, that animates their scale, and handles their drop animation, but that shouldn't really change anything, since i use a consistent transforms .right for the positions, that i never move, never rotate, and never change the scale of

I'm trying to make a reference int field in a class so that the class can modify that int variable directly without caring where it came from. However, it seems C# isn't letting me do that telling me I have to upgrade to C# 11 or something (which I'm also told isn't supported by Unity). So how do I go about doing something like this?

Screenshot_2026-02-13_004916.png
#

It works just fine when it's a fresh ref int declared in the function, but naturally I want a class that can hold onto that reference. I just don't know how I'm supposed to go about doing that. Pointers maybe? But I'm a bit scared to use them since I'm told they're unsafe and the location of the data can't actually be guaranteed anyway

The idea is that it's a command in a JRPG and resource is supposed to be what ever stat is being used as a resource for the command. However, that resource could come from not just any character, but from a select range of stats. It could even come from an item stock. I don't want that distinction to matter, though. At the end of the day anything that should be fed here should be an int and its job is to deduct and/or add to that amount when it is asked to do so

eternal needle
#

what you're thinking of currently just sounds like a nightmare to debug, if it is even possible

eager stratus
# eternal needle you should probably make some interface or event instead then. Like if you store...

That would work if I wanted to just erase the distinction between a stat block and a consumable, but runs into another problem. A consumable only has one variable that can potentially be modified by the interface, but the stat block has like 3. The only solution I can think of to this is to put in a flag for the purpose of the statblock's implementation of the interface, but that flag is completely meaningless for the consumable's implementation

eternal needle
# eager stratus That would work if I wanted to just erase the distinction between a stat block a...

truthfully I don't see the point of anything related to the sample code above. This is basically asking how to externally modify values without a reference to the class
Like what purpose does this other class serve that it's being used to update a bunch of random numbers? There must be somewhere else that calls upon this other class to notify it to update. Move that logic to your consumables/stats instead

eager stratus
#

I just simplified a class to just this problem because I wanted a solution to this problem

#

I didn't want people asking what all the other variables did when it doesn't matter

eternal needle
#

maybe the solution here is really simple

eager stratus
eternal needle
#

a different way would just be to make a new wrapper class with the int you want, so you can pass that class around as a reference instead

#

which is essentially what you're trying to do with this ref int thing

eager stratus
#

I need it stored somewhere and C# is not letting me do that

eternal needle
#

ignore ref entirely here, it wouldnt be needed

eager stratus
#

And, as far as I've been able to test, if I just have a regular int as the field and assign it to the ref int it will simply copy the value. Any modification of that field will have no actual effect on the ref int that was passed in which defeats the whole point

#

I know I can do
ref int resource = ref inResource

But naturally then resource will only last as long as the initializer is running. I don't want that. I want it stored for later modification

eternal needle
eternal needle
#

i think technically a ref struct would immediately solve the one case you've shown, but Im like 90% confident you wouldn't be able to use it in the way you want
nvm I think this was only possible in later c# versions like you said above

#

it has limitations around how you can use it

sour fulcrum
#

You probably want this to be a whole class anyway later down the line incase you ever wanna do other stuff with it eg. perhaps associate front end stuff like text or ui or an event like i think bawsi suggested aswell(?)

ivory bobcat
sour fulcrum
#

when you could bake this into the value class itself

#

(ive done something like ScriptableStat esque stuff in the past)

eager stratus
# eternal needle it isn't needed in the slightest <https://dotnetfiddle.net/7IBTEB>

So you're saying that if I had a class

{
    public readonly Action<StatBlock, List<StatBlock>> action;
    protected TargetTag targetTag;
    event Action<ActionInfo> onCompletion;
    int resource;
    int cost;

    //I should see if the equal operator takes the reference of the variable, too
    public ActionInfo(string name, ref int inResource, int cost, Action<StatBlock, List<StatBlock>> action, TargetTag targetTag) : base(name)
    {
        this.action = action;
        this.targetTag = targetTag;
        this.resource = inResource;
        this.cost = cost;
    }

    public void DeductCost()
    {
        resource -= cost;
    }
}```

And tried to run this code outside of the class

```ActionInfo ultima = new ActionInfo("Ultima", ref cloud.currentMP, 80, SpellEffects.Ultima, TargetTag.Party);

ultima.DeductCost();

print(cloud.currentMP)```

That cloud.currentMP will be 80 less than it was before doing all of this? Or will it just be resource that is 80 less with cloud.currentMP being completely unaffected?
eternal needle
#

im not sure if you actually went through the code I sent above, i dont use ref anywhere

eager stratus
eternal needle
#

i sent you an example with exactly that. they are suggesting the same thing I wrote above

ivory bobcat
eternal needle
#

cause of the ref alone

eager stratus
#

It simply won't do anything because it's resource being modified and not currentMP

#

I want resource to work as a pointer to currentMP, but I'm not really sure if I even should be using pointers for this

sour fulcrum
# 
class StatValue
{
  public int Value { get; private set; }
}

//eg. some thing that has a ref to whatever stat you want
private void ModifyStat(StatValue stat, int value)
{
  stat.Value += value;
}
#

similar to bawsi's just even more reduced

ivory bobcat
#

Well.. you're not assigning anything to inResource so it doesn't need to have the ref modifier

eager stratus
sour fulcrum
#

why wouldn't it

eager stratus
#

Oh wait I forgot to put ref

eternal needle
sour fulcrum
#

int's are not naturally reference based, classes are

#

so just have an int in a class

eternal needle
#

you do not need ref anywhere here

sour fulcrum
eager stratus
sour fulcrum
#

You'll probably naturally realise you can put a lot in that class

#

but in that example yes

I guess I can try it

that looks like a 3d collider, that wouldn't collide with 2d colliders

#

haven't we been over this

verbal dome

The green sphere is the particle collision shape/bounds

#

What is the question though? Like what is the screenshot supposed to show, the colliders are not visible

tired python
#

all my other colliders are in 2d 💀

#

my game in 2d

verbal dome
#

It is 2D. There's no 3D collider in that screenshot, Chris mistook the green sphere for a 3D collider

tired python
#

O_O

verbal dome
#

The whole point of the Triggers list being of type "Component" is that you can assign both Collider and Collider2D to it

naive pawn
#

i may have misinterpreted them though

tired python
verbal dome
#

But it's effectively 2D if you're using 2D triggers in the list

naive pawn
#

(well not a collider since it's not the same color, but i assumed it was using collider shapes under the hood)

verbal dome
#

anyone know why it On particle trigger gets called iff outside is set to callback?
🤔

tired python
#

check out the log and you will understand

#

i genuinly don't understand how people did unity before unity discord became a thing

verbal dome
#

So it is triggering the callback when you dont want?

tired python
#

it only triggers callback on outside

verbal dome
#

Seriously, don't assume that people understand what you mean just from a couple of videos with multiple things happening.
Prefer text explanations

verbal dome
tired python
# verbal dome And what do you expect?

i expect it to do that when enemy collider is inside the particle, but that's not the only problem. Even if I were to increase the radius of this trigger's radius scale field to a very high amount, it still triggers the callback even though the enemy collider should be inside this radius, and not outside of it

verbal dome
#

Why do you expect the "outside" callback to fire when it is inside?

tired python
#

if only outside has callback and everything else has ignore, callback should not happen when enemy collider is inside, entering, exiting this radius

tired python
#

i don't expect it to

verbal dome
#

i expect it to do that when enemy collider is inside the particle
Very contradictory but okay

sour fulcrum
#

Are you sure it’s the enemy triggering that? Those logs don’t confirm that

tired python
#

wait, let me explain what I want, and what i am seeing in one full elaborate explanation

naive pawn
#

-# this was expected of you from the start, man

verbal dome
#

The docs don't state if the particle needs to be inside/outside of all or any of the colliders

#

So that might be related

tired python
#

What I want:-

  • If enemy collider is outside particle, don't do anything.
  • If enemy collider entered particle or is inside particle, trigger OnParticleTrigger

To achieve this, I set Enter and 'Insideto Callback, and rest to Ignore
What I observed, nothing was triggered.

So I started tinkering with the various things and found out the following:-

  • Iff I set Outside to Callback, does any form of triggering ever happen, in any other scenario, where Outside has been set to Ignore, nothing gets triggered
tired python
verbal dome
#

Did you use OnTriggerStay/OnTriggerEnter or OnParticleTrigger?

#

Because the OnTrigger stuff isn't used by particle systems

tired python
#

changed it

verbal dome
#

Right, I see your edit

tired python
# 
void OnParticleTrigger()
    {
        Debug.Log("Particle Trigger Detected."); 
    }
sour fulcrum
naive pawn
verbal dome
#

So it would have to be either of the Duck colliders

#

@tired python So when the Enter/Inside callback did not work, were the particles inside both of those colliders or no?

#

I'm not sure if it requires all or any

sour fulcrum
# tired python

am i dumb why are the game view and scene view different here

verbal dome
#

(In any case - I avoid using particle collisions for gameplay logic and treat them as purely visual components)

verbal dome
tired python
verbal dome
#

Well no, just some physics queries like raycast/overlapcircle etc.

#

Ofc it is harder than just enabling a checkbox in the particle system

#

But at least I know what's going on :p

#

Is your particle system at zero Z position?

tired python
#

the goddamn spline is set in the same xy plane, how the hell does z happen to change

#

z is changing everytime the duck moves

swift crag
#

Select the individual spline knots and make sure they have a Z position of zero

tired python
#

excuse me?

image.png
swift crag
#

If they're in Bezier mode, also make sure that both handles are at Z=0

verbal dome
#

I would expect Z to not matter in 2D but maybe there's some quirks with particle system since it uses both 2D and 3D collisions

tired python
swift crag
#

then click on the spline knots and make sure the handles are flat

#

(you may want to leave 2D mode to view this)

swift crag
verbal dome
#

When does 2D collision use Z?

naive pawn
verbal dome
#

Ah yeah that!

tired python
swift crag
#

That’s the erosion of the knot itself. I believe that does mean that the handles are sticking straight out on the XY plane, though

#

So that’s correct

tired python
swift crag
#

"Reverting back"?

tired python
# swift crag "Reverting back"?

i manually set it to 0, then i select another knot and then i select the same knot once again, and i see it have a value other than 0

#

like this

swift crag
#

hm, I'm not sure – the rotations might be getting affected by the neighboring knots

#

I'd start by getting the knots rotated correctly

#

notice how they're at a 90 degree angle to the 2D plane

image.png
tired python
swift crag
#

I think you can just give them a Y rotation of zero to flatten them out
