having done almost the same thing in highschool, its not entirely pointless if you get the chance to see it come to life. But my friends and i looked back and realized we did everything in the shittiest way possible

[loud wharf]

I'm just a freshman in university.

[shadow nacelle]

how I feel right about now but atleast making a 2d game was hella fun

[loud wharf]

We didn't have coding lessons in high school, I did media arts tho.

[shadow nacelle]

even if it sucked!

[devout hill]

uh hi could someone help me understand gameobjects activation and like when methods are called or not

I have some very simple code which just prints a gameobject's activeSelf value before and after calling SetActive and its false both times

            Debug.Log($"{gameObject.name} is active: {gameObject.activeSelf}");
            gameObject.SetActive(true);
            Debug.Log($"{gameObject.name} is active: {gameObject.activeSelf}");

which yields the following log

some things online have led me to believe that maybe a script cant activate the gameobject that its on? but that is what I have been doing this whole time

the only thing that has changed is that now this object is late initialized, like i moved the initialization code from Start to OnEnable and then it starts out disabled and gets enabled later

to me, the specifics of when functions will be called is all magic

initialization order for one, but in this case its what gets called when a behavior is enabled and a gameobject activated

according to the inspector, this is an enabled script trying to call SetActive(true) on its inactive game object, which should work in my head

[leaden ice]

this should work fine

possibly some other script has an OnEnable that deactivates the object or something?
Or perhaps an exception is being thrown in some object's Awake?

[dusk apex]

Try https://docs.unity3d.com/ScriptReference/GameObject-activeInHierarchy.html if you've got an inactive parent.

[leaden ice]

activeSelf I would expect to work properly here no matter what the parents are doing

[devout hill]

the script is on the root object which is disabled, none of the parents are disabled

[leaden ice]

can you show the rest of your console window?

[devout hill]

sure

[dusk apex]

Update and whatnot are not called from inactive objects / disabled components.

Surely you're calling this function from another script

Or when the object isn't inactive or component isn't disabled.

[devout hill]

indeed i am

heres the first thing, this is just the inspector and the hierarchy before starting the game

the thing i put a blue rectangle around is the script calling SetActive

[dusk apex]

So the object is active.

The component is disabled.

[devout hill]

and here it is when the game is started

[leaden ice]

Ok actually I have a theory here now - I think you're trying to call SetActive on a prefab.

[devout hill]

object deactivates itself and the component enables itself

[devout hill]

isnt it all gameobject once instantiated?

[leaden ice]

sure, as long as you call the function on the instance not the prefab

[devout hill]

i thought prefabs were just an editor concept

[leaden ice]

prefabs are not just an editor concept

prefabs are GameObjects that exist in memory but not in the scene

[dusk apex]

Where are you referencing this component?

[leaden ice]

Yes - how and where are you referencing the script and calling the function from?

[devout hill]

it is in the base class implementation of this UI script. its called BDefaultBuildingConnectedUIImplementation and it has a function that looks like this:

        public virtual void Open(IBuildable buildTarget)
        {
            Debug.Assert(buildTarget != null);
            // why are we opening a prompt if the buildable can't even be built?
            Debug.Assert(buildTarget.allowedFacilities.Count > 0);
            if (currentBuilding == buildTarget)
                Debug.LogWarning($"{this} opened while already open.");
            currentBuilding = buildTarget;
            BOpenCloseEventManager.InvokeUIOpen(this);
            Debug.Log($"{gameObject.name} is active: {gameObject.activeSelf}");
            gameObject.SetActive(true);
            Debug.Log($"{gameObject.name} is active: {gameObject.activeSelf}");
        }

[leaden ice]

this is the code itself

We want to see where you're calling it

[devout hill]

its child, the thing im trying to call Open on, calls this function with base.Open()

[leaden ice]

ok and... from where is THAT code called?

[devout hill]

let me show you a stack trace

uno momento

[leaden ice]

at some point you're doing someReference.Open(something);

I want to know where someReference came from

[loud wharf]

Visual Studio will show how many references a method has.

Just click on it.

[devout hill]

someReference is this

[leaden ice]

Looks like it's from a button

[devout hill]

        public override void Open(IBuildable building)
        {
            base.Open(building);

[leaden ice]

can you show how the button listener is configured?

[devout hill]

the child class does this ^

[dusk apex]

But this is disabled/inactive so what's causing everything to trigger?

Could probably ask #💥┃post-processing

[devout hill]

there is a separate game object which implements IPointerClickHandler

[leaden ice]

uhuh and this is called from BBuildTarget.OnEnable

[leaden ice]

yes show that

basically where is the reference coming from that you're calling Open on in the first plce

[devout hill]

public class BSelectable : MonoBehaviour, ISelectable, IPointerClickHandler
    {
        public event ISelectable.SelectedEventHandler Selected;
        public event ISelectable.DeselectedEventHandler Deselected;

        public void Deselect() { Deselected?.Invoke(); }

        public void OnPointerClick(PointerEventData eventData)
        {
            if (BSelectionManager.RequestSelection(this))
            {
                Selected?.Invoke();
            }
        }
    }

this thing has an event

[leaden ice]

uhuh... and where do you attach a listener to the event lol

[devout hill]

other scripts subscribe to that event

[leaden ice]

cut to the chase

[devout hill]

yeah lets follow the chain!

[dusk apex]

How's the inspector look?

[devout hill]

i sent a couple images earlier

[devout hill]

editor before starting

[dusk apex]

For the selectable component?

[devout hill]

and editor after initialization

good question

[devout hill]

there is a function subscribed to that function which calls Open on the child and then that calls the parent Open

the function is a lambda

the reference to the popup comes from a [SerializeField]

            selectionComponent.Selected += () =>
            {
                Debug.Assert(buildPrompt != null);
                if (built)
                {
                    Debug.Assert(selectedFacilityUI != null);
                    selectedFacilityUI.Open(this);
                }
                else
                {
                    buildPrompt.Open(this);
                }
            };

[leaden ice]

rught so... selectedFacilityUI

where does that come from

or buildPrompt

not sure which is relevant here
What are those references pointing at?

[dusk apex]

    Debug.Log($"Supposedly Inactive: {gameObject.name} is active: {gameObject.activeSelf}", this);
    gameObject.SetActive(true);
    Debug.Log($"Supposedly Active: {gameObject.name} is active: {gameObject.activeSelf}", this);```

Which object is highlighted?

[devout hill]

buildPrompt comes from this:

       [SerializeField]
        GameObject buildPromptObject;

which is gotten by doing this:

buildPrompt = buildPromptObject.GetComponent<IInterfaceConnectedUI<IBuildable>>();

[leaden ice]

It's serialized

[devout hill]

that was poorly explained but yeah

[leaden ice]

surely it's assigned in the inspector

that second line is reading that object, not assigning it

what did you assign to it in the inspector

[devout hill]

if i click that, it highlights the gameobject in the scene

this is true for all instances of this clickable object

[fluid lily]

I see this most often when something is unassigning it at runtime

[devout hill]

so im aquiring a reference to the deactivated gameobject from a serialized field

and yeah in the middle theres a click handler followed by an event followed by a virtual function call. and to initialize it theres a GetComponent call

[leaden ice]

I would try Dalphat's thing now

[devout hill]

i dont have IInterfaceConnectedUI<IBuildable> serialized because its a templated type and unity doesnt know how to serialize it so i just take in a GameObject and then call GetComponent

okay excellent trying that now

[leaden ice]

Unity actually can handle serializing the generic type just fine these days it's more that it's an interface that's an issue.

[devout hill]

oh interesting

that makes sense

[devout hill]

it highlights the deactivated root object correctly

[leaden ice]

I would try putting OnEnable and OnDisable on the script and see if something funny is happening inside the SetActive call

You might have an OnEnable that's deactivating the object for example

[devout hill]

OH SHIT

i bet thats it

okay so wait

if i have an OnEnable function on a behavior. the game starts, both the behavior and its parent object are enabled/active respectively

and then I disable the behavior

then deactivate the gameobject

then reenable the behavior

then reeactive the game object

OnEnable in that script gets called twice?

[leaden ice]

I'm not actually sure

[devout hill]

without OnDisable ini between

i shall find out

[leaden ice]

Debug.Log would tell you

[devout hill]

oh wow

okay so yeah deactivating a gameobject calls ondisable for all components

the solution for me is to make sure onenable doesnt get called more than once

[leaden ice]

So what was the result?

I'm curious?

Does OnEnable get called twice in that scenario?

[devout hill]

i actually cant figure out whats going on

this seems inconsistent but also im testing it in a weird way

[ivory pasture]

can i snap a game object's transform to the center of a grid cell? (2d)
without using grid layout group

[devout hill]

i want to know too but unfortunately its almost 2 in the morning and ive got an exam tomorrow lol

thanks for all your help praetor

will update you if i test it

[leaden ice]

In code? Use the Grid component

[ivory pasture]

what about inspector?

there are cells that the player can snap into, but its not in every cell in the grid

[drifting crest]

how can i make a system in unity where there is a video playing on a 3d cube but ain't visible untill i hover with another cube on that cube

[lean sail]

which part do you struggle with, this is like 3 different problems in one

[drifting crest]

the visiblity part or we can call it the xray masking system

[lean sail]

visibility can be as simple as disabling a game object. Im not sure wat you mean "hover with another cube on that cube". You likely want a raycast here, but you should probably describe more

[drifting crest]

okay so like there is a cube on which the video is playing but it isn't visible through the main camera and i have another cube that is controlled by my mouse and when i control that cube and hover it over the video playing cube then i should be able to see the video

[lean sail]

i still dont get what you mean hover it over, i assume this is like a remote and you are pointing it at the other cube. In which case you would want to raycast from the held cube using its .forward as the direction

Hi everyone, I was wondering if anyone had an idea for a clean solution for generating colliders along a chained bezier curve.

My current thought was to use Sphere Colliders or Box Colliders and place them in steps of some distance (given that I don't need it 100% perfect). However I noticed that the Sphere Collider cannot take an position offset and the Box Collider cannot take a rotation offset.
This is only an issue given I want to put the colliders on a single game object rather then having many / 100's of GameObejcts.

That said, if anyone has a better idea on how to do collision checks for curves I would appreciate the help

[drifting crest]

https://youtu.be/JUgqWTi5AZE?si=_9uUaVyAJCLZXiBi

I mean like this

[round violet]

when instantiating a prefab can I pass some vars directly ? instead of passing them after the constrcut

[loud wharf]

Nope.
You're not constructing the GameObject, unity does.

[lean sail]

whats this for, are you making like a rope system? if we're just talking about collisions along a single curve then the easiest way might just be modelling the curve and using the mesh collider

[lean sail]

if you make your own static method then yea you could make it feel like you're doing this. but in reality that static method will only end up instantiating and settings the variables itself

[simple ridge]

Its to make an interactable edge for walls that a player can interact with on collision. The best way I can describe it is kind of like a wall climbing mechanic where there will be ledges on a wall that a player can attach too and shimmy across.

[round violet]

okay ty

[simple ridge]

Since the walls can be curved I figured the best solution would be to use a curve, this way I can move the player along said curve by just passing in a value for there position.

The only issue is that if I have many of these climbable surfaces in a level then that will be alot of colliders, and even worse on top of it alot of game objects.

[lean sail]

maybe you can experiment with runtime mesh generation, assuming this doesnt need to change very very often. i havent done it much personally but I think it'd be better than 100s of game objects like you said.

[simple ridge]

Ah good shout, a mesh collider could solve this! I could generate a mesh using the curve and then use a mesh collider.

Thank you!

The mesh should be a constant, and wont change, so I'll either write something to pregenerate it or just get it generating on start. I've written mesh gen code before for this sort of thing but I didn't think a runtime mesh could work with the mesh collider. xD

[forest imp]

Is there a way to make rule tiles account for other rule tiles? for example, I have these diagonal tiles. Now of course they wouldn't be diagonal if they had a tile of the same type to the top or corner. Is there a way to make it such that it accounts for the existence of any tile rather than just other smart tiles of the same type? perhaps through custom tile scripts? Thanks

[deft timber]

this is a code related channel

[forest imp]

I assume the answer would be related to custom tile scripting

[deft timber]

if you would have some code issues with this exact case then just ask here

make research, try it yourself, when you face issues we can help

[unreal egret]

There you go !

[knotty sun]

still no line number. which is line 10

[unreal egret]

my bad, mate

[knotty sun]

so _boss is null. Debug it. chances are you have multiple instances of the script

[unreal egret]

I never instantiate it, I only have one copy of the gameobject and as I've shown, my serialized field is referenced as it should

[knotty sun]

still, the run time is not lying. Debug it
if (_boss == null) Debug.Log($"Boss is null on {gameObject.name}",this);

[unreal egret]

I know it is not lying, I just don't understand how it's null is all,

[knotty sun]

well if you debug you will find out, that is what debugging is all about

[unreal egret]

yes, I've been debugging. I have not found a solution, so I'm hoping for some hints, honestly. Do you know what could render it null ?

[knotty sun]

there are lots of reasons it could be null. First you need to identify exactly where it is null

[unreal egret]

well right there, it's the only place I reference the object

[knotty sun]

prove it

[unreal egret]

I'll give a look through all of my files

[knotty sun]

that is not how to debug

[unreal egret]

then guide me, I'm on a wild goose chase, here

[knotty sun]

start by adding the line I showed and then screenshot your console

[unreal egret]

I did,

Boss is null on Bossroom
, but we already knew that

[knotty sun]

no we did not know, you assumed, now we know

and I said screenshot the console so we can see the full stack trace of the error

[deft timber]

also if you can show if the reference is still assigned during runtime?

[deft timber]

that is not a stack trace of the error

[unreal egret]

still there

[unreal egret]

isn't this

Boss is null on BossRoom
UnityEngine.Debug:Log (object,UnityEngine.Object)
Debug:Log (object,UnityEngine.Object) (at Assets/Scripts/Dev/Debug.cs:244)
BossManager:ActivateRoom () (at Assets/Scripts/BossManager.cs:10)
BossManager:OnEnable () (at Assets/Scripts/BossManager.cs:22)
The stack trace ?

[deft timber]

no

we want a stack trace of the ERROR

not of the debug log you just put

[knotty sun]

screenshot full inspector of the gameobject

[unreal egret]

There you go !

[knotty sun]

That gameobject is Boss not BossRoom where the error is on

[unreal egret]

so it nulls itself ?

[knotty sun]

show the inspector for BossRoom

[rapid pivot]

Uh can someone help me with something? I got an error I can't figure out.

[deft timber]

dont ask to ask please

https://dontasktoask.com/

[rapid pivot]

Sorry, wasn't sure if this was the right spot to ask.

I got this error, and I don't understand it, especially since I'm not using poiyomi on this project anymore. I changed it all to another shader.

[deft timber]

if you aren't using it anymore, then just delete it?

[rapid pivot]

I removed it from the folder, and it starts spitting out like a hundred errors

[unreal egret]

Yep that was it. I had the Manager twice and it fucked everything up. thanks for everything, guys

god, that's annoying, I had removed it, too

[prime quarry]

I followed the instructions online with creating records: record Alarm(float TimeLength, bool Loop); but it gives an error predefined type is not defined or imported

[knotty sun]

Did I not say multiple copies of the script? Next time don't just assume, debug

[deft timber]

well you didn't

you have exact path of it

[unreal egret]

I thought you meant multiple copies of Boss, which is why I had turned down the idea, my bad

[rapid pivot]

I put it back in to get rid of the 100+ errors, so it's there now. I'll show what it starts to look like after I remove it

[prime quarry]

More specifically 'System.Runtime.CompilerServices.IsExternalInit' is not defined or imported

[dense swan]

anyone using VSCode?
why this gives error? It's the only OnDrawGizmosSelected that show error. The other is fine. The difference between this and the other OnDrawGizmosSelected is that this one is written in VSCode.

[deft timber]

we have no idea what are you trying to create

give some context, some code

learn how to share issues and how to ask for help

[prime quarry]

Im just trying to set up a record to add to a dictionary

Each record is an alarm in a dictionary of alarms

[deft timber]

just show the code

[knotty sun]

that looks like you have the method declared inside another method

[deft timber]

there is no such thing as record for dictionaries

[dense swan]

wowowowow you are right!! thanks, very embarrassing mistake. Looks like I'm too used to Visual Studio automagically fixing my mistakes.

[rapid pivot]

Any ideas what I'm doing wrong to go from just a few errors to 60+?

[knotty sun]

the words 'local function' are the giveaway there

and the fact that your braces are misaligned

[prime quarry]

  record Alarn(float TimeLength, bool Loop);
  Dictionary < Timer, Alarm > alarmsDic;

  public bool initialized;

  public void Setup() {
    alarmsDic = new Dictionary < Timer, Alarm > ();
    initialized = true;
  }
}```

[deft timber]

do you have your IDE configured?

this error has a lot of spellings and errors

what is Timer? is this your own class, or are you using (you shouldn't) System.Threading.Timer class?

[prime quarry]

Timer is an enum

Hello, I have a question.
I have a character that uses Character controller for movement. I also have a object pick up mechamic. So when I pick up the object and walk around with it it just goes thru the walls even tho it has a collider. I tried adding another collider to the player that turns on when the object is picked up but it still goes thru the wall. The character stopps when the character controller collider hits the wall but not when any other collider does. Any idea how I can solve this? Thanks

[cosmic rain]

How are you moving the picked object?

If you want it to collide, you should make sure it's controlled by physics.

[neon plank]

How can I modify a direction so its vertical and horizontal angles in comparison with another direction doesn't get too far awaiy? Basically clamp it.
I tried this but it's not working:

float3 center = position + aimingTargetCenterOffset;

float3 targetDirection = MathUtils.ClampMagnitude(shootingPosition - center, baseAimingMagnitude);

float3 rotatedBaseDirection = math.rotate(rotation, baseAimingDirection);

float3 axis = new(0f, 1f, 0f);
float3 plane = math.rotate(rotation, axis);
float3 targetDirectionProjection = MathUtils.ProjectOnPlane(targetDirection, plane);
float3 rotatedBaseDirectionProjection = MathUtils.ProjectOnPlane(rotatedBaseDirection, plane);
float angle = MathUtils.SignedAngle(targetDirectionProjection, rotatedBaseDirectionProjection, axis);
angle = math.clamp(angle, -aimingTargetMaximumHorizontalAngle, aimingTargetMaximumHorizontalAngle);
float3 direction = math.rotate(MathUtils.AngleAxis(angle, plane), rotatedBaseDirection);

axis = new(1f, 0f, 0f);
plane = math.rotate(rotation, axis);
targetDirectionProjection = MathUtils.ProjectOnPlane(targetDirection, plane);
rotatedBaseDirectionProjection = MathUtils.ProjectOnPlane(rotatedBaseDirection, plane);
angle = MathUtils.SignedAngle(targetDirectionProjection, rotatedBaseDirectionProjection, axis);
angle = math.clamp(angle, -aimingTargetMaximumDownwardAngle, aimingTargetMaximumUpwardAngle);
direction = math.rotate(MathUtils.AngleAxis(angle, plane), direction);

axis = new(0f, 0f, 1f);
plane = math.rotate(rotation, axis);
targetDirectionProjection = MathUtils.ProjectOnPlane(targetDirection, plane);
rotatedBaseDirectionProjection = MathUtils.ProjectOnPlane(rotatedBaseDirection, plane);
angle = MathUtils.SignedAngle(targetDirectionProjection, rotatedBaseDirectionProjection, axis);
angle = math.clamp(angle, -aimingTargetMaximumDownwardAngle, aimingTargetMaximumUpwardAngle);
direction = math.rotate(MathUtils.AngleAxis(angle, plane), direction);

float3 result = center + direction;

[placid compass]

I am just paranting it to the characters torso for now, but I am open to suggestions

[cosmic rain]

Instead of parenting it, move it towards a point in front of the controller via velocity/forces/MovePosition.

[placid compass]

Will try that now

[frosty token]

if you want to keep it physics based, you can also try a SpringJoint, it will be more flexible, for example knocking the object into something could "break" the spring and make it drop etc.

[placid compass]

I will try springs since the moving to the position approach is very buggy

[frosty token]

small hint, i prefer to make to put the spring component on the "owner" of the object, not the object that is being picked up (usually the heaviest object should have the Joint, to improve stability)

[rapid pivot]

I've got a single error on a project and I'm so confused about how to fix it. Does anyone have any ideas?

[knotty sun]

which version of Unity are you using?

[main shuttle]

https://docs.unity3d.com/ScriptReference/TextureFormat.RGB48.html

[rapid pivot]

2019.3.15f1
which is what the project I'm doing requires apparently

[main shuttle]

It's TextureFormat? Not TextureImporterFormat?

[rapid pivot]

that error is all I know

There was two other errors, but by // in the helper.cs it got rid of them. THAT one however if //'d just throws like 65 errors

[knotty sun]

That is your problem, RBG48 was introduced in 2020.2

[rapid pivot]

is there a way to get around it? I dont even know what its using it in

[knotty sun]

The error message tells you exactly where it is being used.
You have a choice, stop using the asset, find a version of the asset compatible with 2019.3 or update to at least 2020.2

[rapid pivot]

I don't know if the project will work on 2020.2
and I wouldn't know where to look for that helper.cs

and if I remove the asset it throws so many errors

[knotty sun]

the full path is in the error message

[rapid pivot]

no, I mean to replace it. I have the .cs opened

[knotty sun]

so show the code

[rapid pivot]

the whole cs?

[knotty sun]

the part throwing the error

[rapid pivot]

the two with // were throwing errors, but that alone fixed those.

[knotty sun]

just comment out the line

[rapid pivot]

I did. I said that, and that it throw like 60 errors if I do, in the vein of:
"Assets\ABI.CCK\Scripts\Runtime\OnGuiUpdater.cs(74,16): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)"

So I undid that and it went back to 1 error.

[knotty sun]

that is totally unrelated

[rapid pivot]

Then why does it happen the second I comment it out? there's TONS of errors that pop up.

[knotty sun]

because compilation is stopping because of the first error, once you fix that then compilation continues finding other errors. This is totally normal behaviour

[rapid pivot]

okay... so what are THOSE errors then? I'm so confused...

[knotty sun]

They are telling you what the problem is, can you not read them

[rapid pivot]

No. I haven't used Unity in a few years and I'm trying to do a project but no, I don't know what this means.

[knotty sun]

my guess is you are trying to use assets which are not compatible with your Unity version so why are you doing this if you cannot fix simple errors?

[rapid pivot]

Cuz I'm literally too poor to hire someone else to do it, no need to make me feel like crap for it

[knotty sun]

I meant why are you using assets not compatible with your Unity version?

[rapid pivot]

I'm literally following a guide and someone else's tips who was helping me troubleshoot.

The version, the specific version of the assets, everything.

[knotty sun]

well you've got something wrong somewhere if you have compatibility problems with 2 different assets

[rapid pivot]

Well I have no idea, I've been troubleshooting for four hours, trying to get help the whole time, and on top of feeling stupid for not being able to fix simple errors, I don't have any idea of how to fix it.

[knotty sun]

Do you know what Text is?

[rapid pivot]

literal text or a file called text or what?

[knotty sun]

no the Text refered to in the error message

[rapid pivot]

No. Nor do I know the "UI" or "EventSystems" or "InputField" etc

[knotty sun]

All the same problem.
They refer to classes contained in a Unity namespace
Obviously the code you have is looking in a namespace which is not the same as used by 2019.3
So. First thing to do is find out which namespace 2019.3 is expecting. Then find which namespace the code is using and change it

[rapid pivot]

Okay... it's calling for everything from Text to UI to Unity Engine and more

there are 59 red errors

[knotty sun]

take them one at a time, you will find that as you solve one, many errors will disappear

[rapid pivot]

Okay, so... let's start with Text. OnGuiUpdater.cs is calling for that... do I have to comment it out or something?

[knotty sun]

did you not read what I wrote?

[rapid pivot]

Okay, yes I did. But that's what I'm saying. "find the namespace and change it".... Change it HOW is what I'm asking

[knotty sun]

find out which namespace 2019.3 is expecting

[rapid pivot]

...I have no idea where to look for that. Is it by the cs?

[knotty sun]

in the Unity docs

actually your IDE should suggest it to you

[rapid pivot]

okay, I'm a complete noob when it comes to this. I have no idea what any of these terms mean or where anything is located.

[knotty sun]

search the Unity 2019.3 docs for the Text class and see which namespace it is in

[rapid pivot]

Still have no idea where those docs are. You need to explain it to me like I know computers but not unity at all.

[knotty sun]

do you not know how to use Google?

[rapid pivot]

yeah, I do, but it's not helping because google 'where are unity docs' isn't gonna get me the answers I need in a reasonable time...I'm asking you because you're someone who's helping me and knows the answers to the questions I have.

You know as well as I do that unity is not beginner friendly, which is why I"m here asking for help

[deft timber]

that is a weird theory xd

[rapid pivot]

I literally googled it

[deft timber]

why isn't unity begginer friendly?

[knotty sun]

to start with think about your google search words.
Unity Scripting API will bring you straight to where you need to be

[deft timber]

it has a lot of perfectly begginer friendly learns

[rapid pivot]

Ah yes because you said any of those words to look for. Not just "unity docs"

[deft timber]

clear documentation, well documented

googling is a skill

you need to learn

[deft timber]

hardly disagree, unity is begginer friendly with proper googling

[knotty sun]

if you expect me to think for you, you will be sorely disappointed

[rapid pivot]

I don't expect that, I expect help when I say I need help and someone comes along

[deft timber]

and the help was given

literally he even gave you a google phrase

[rapid pivot]

i literally searched that.

[deft timber]

then as i said, you need to improve your googling skills

if you cannot find docs for "Text" class in unity

[rapid pivot]

if you don't wanna help then don't jesus

[main shuttle]

Unity is one of the most beginner friendly engines there is though, that's why it is as popular as it is.

[deft timber]

I am trying to help, saying that you should improve your googling skills

it is not meant to be offending

googling properly is not an easy skill

[knotty sun]

it's that simple

[deft timber]

or just google "unity docs", and find text in there

i don't really understand what is so hard about it 😄

[rapid pivot]

Yet again you're not making sense. "Docs" had me thinking you mean files on my computer, on computer documentation

[deft timber]

that doesnt make much sense

[rapid pivot]

you've never gotten a readme?

[deft timber]

readme is a readme, not a documentation

apparently when he said "find unity docs about Text" he meant literally unity docs (online) about Text component

[rapid pivot]

APPARENTLY, you didn't even know!
\

[deft timber]

if you didni't understand that and started to look for phyiscla files on your PC then 🤷

[rapid pivot]

You had no idea he meant online documentation either, so how was I, a literal noob, supposed to know that?

[deft timber]

but what other form of documentation besides online you expected wtf

did you download entire unity documentation as files on your pc?

[rapid pivot]

I don't know, MAYBE the version of Unity has some documentation with allllll the other files it downloads?

[deft timber]

anyway, honest advice, practice your googling skills, cut the offtopic please

[rapid pivot]

again, nooob, how am I supposed to know

[knotty sun]

this is going nowhere, so let's back up a minute. Can you screenshot your IDE with the code in error shown

[rapid pivot]

I sure can't because you still haven't told me what an IDE is

[deft timber]

lol

[rapid pivot]

I don't know these terms.

[knotty sun]

I give up

[deft timber]

again you can just google what is an IDE instead of waiting for someone to explain it to you lol

[rapid pivot]

I can see that I won't get even any simple help here. What a wonderful 'official' server, too busy insulting you because you don't know all these terms when you're literally asking for help and say "I'm new to this".

Thanks for wasting both our time.

[deft timber]

You see, the problem is that we are providing help, but you just don't understand it

You need to understand the world we live in, no one (usually) will spend their time, explaining you things, that you can just google in 10 seconds yourself

No one has insulted you btw

You can't get help if you don't understand it

[hexed pecan]

Being told to google what an IDE is is not a personal attack on you. It's what we tell everyone who doesnt know

[rapid pivot]

Googling that is one thing, I can look that up because I"m being told specific terms

'unity docs' when not clear if online or included documentation on the install and not saying what they're even called is not something I can just KNOW

[deft timber]

right there instead of wasting 10 seconds writing this answer, you could just spent that 10 seconds to googling what an IDE is, educate on that, then send a screenshot as asked

[hexed pecan]

People expect some basic knowledge when in the general (non beginner) channel

Including that docs are online

[rapid pivot]

I'm here because the error I came here for originally stumped people so I figured it was beyond 'beginner' level bug fixing

[deft timber]

but you are a begginer

you came to general channel, where we expect people to know the basics, but you don't even know the core (what an IDE is), so how exactly do you expect us to help you not using programming terminology to help with a programming issue?

[rapid pivot]

did you ever once say "hey you're clearly a beginner, you should take this to beginners"

[deft timber]

ehh im done

[knotty sun]

@rapid pivot Over the course of the last hour I have done nothing but try to help you, in fact I did fix the error you originally came with. However you have done nothing to help yourself. I don't know if you were expecting a magic wand to wave over your problems and make them magically go away, that is not going to happen. You need to put in some effort if you expect help but you seem unwilling or unable to do so

[rapid pivot]

You did what I said I did before coming here. I literally said "I commented it out but then it threw more errors, so I undid it." You have been trying to help and I APPRECIATE that, but you have to realize I also said I'm new to this stuff and don't know these terms. If you tell me the NAMES of things to look up, I'll do it, as I've been TRYING to.

[deft timber]

Again, you don't know a term - you google it, instead of waiting for someone to explain it to you and get angry over it that he doesn't want to help, period

[rapid pivot]

Xaxup, if you're not helping this doesn't concern you. Help or don't.

[deft timber]

That is how it works, and you need to adapt, not we

[deft timber]

You cannot be helped in my opinion without even a basic googling skills, and a understanding how internet works, but good luck on your adventure, i cut off from this talk now

[forest imp]

For a custom rule tile script, how can I include tiles which fall under other rule tiles in the list of neighbors?

[forest imp]

Adding onto this, I assume Unity itself calls the 'applyneighbors' method? I can't find anywhere else in the project it might be called from.

[round violet]

Any ideas on how i could create a enum (in c# i suppose) and use it in a VSG ? (Switch on enum)

Or even if it's supported by unity

[spring creek]

Enums and switches are c# and have been around long enough to definitely be supported by unity

Not sure what vsg is though

[main shuttle]

I think he means Visual Scripting Graph

Or Vulkan Scene Graph 😛

[spring creek]

Ahhh, then I have no idea

I recommend just doing code, it's honestly as easy, or easier sometimes

[main shuttle]

Anyhow, if it is visual scripting, ask in #763499475641172029

[round violet]

Yup

[round violet]

Because of my studies domain i am forced to use VS

[main shuttle]

Yeah I agree, but we are programmers, I can understand it a bit if your a game designer only that want to test something real fast without needing to bother a programmer for it.

[round violet]

I would love to use C

[brave lintel]

Hello everyone, I have a strange behavior in my build. After having a headless dedicated server build, lately I started to get duplicate console messages. Any idea why this can happen and how to solve it?? Response would be much appreciated!

[spring creek]

Well unity uses c#
Not sure of an engine that uses C itself, but there probably is one
Sorry though, I don't know much of anything about visual scripting. Way too hard to be worth it for me

[round violet]

When i say C i mean all C

Like cpp and c#

[round violet]

And no problem

[somber nacelle]

those languages are notably not C. and if you mean C-like languages or languages based on C then don't forget to include the dozens of others

[fervent furnace]

[forest imp]

Adding onto this in case anybody cares at all, this is the solution I came up with. Feel free to critique this if it's inefficient

[spring creek]

Well there are a lot of languages that come out of c. Best to not refer to it like that honestly

Edit: ah, laggy discord

[neon plank]

Given two vectors, how can I get the individual angles of each axis, and then create the second vector from the first one applying the rotations given by those angles? (I know this is redundant, but my idea is to modify a bit those individual angle axis)

[leaden ice]

what does "individual angles of each axis" mean?

can you draw a picture of what you want perhaps?

[neon plank]

How much I must to rotate the x, the y and the z

[leaden ice]

to go from the first vector to the second?

[neon plank]

Yes

[leaden ice]

I would skip the "individual angles" bit and just use quaternions

https://docs.unity3d.com/ScriptReference/Quaternion.FromToRotation.html
FromToRotation gives you the quaternion to go from one vector to another

[neon plank]

I need the angles because I plan to clamp them

[leaden ice]

You can still use FromToRotation and then just call .eulerAngles on it if you really want euler angles.

[neon plank]

Ok, I will try that

[modern tinsel]

for (int i = 0; i < numberOfObjectsToSpawn; i++)
    {
        int attempts = 0;
        bool positionIsValid = false;
        Vector2 randomPosition = Vector2.zero;

        while (!positionIsValid && attempts < maxAttempts)
        {
            // Attempt to generate a random position
            randomPosition = GenerateRandomPosition(bounds);

            // Check if there are no colliders within the sphere
            if (!Physics.CheckSphere(new Vector3(randomPosition.x, randomPosition.y, 0f), minDistance))
            {
                positionIsValid = true;
            }

            attempts++;
        }

        // If a valid position was found, spawn the object
        if (positionIsValid)
        {
            Instantiate(objectToSpawn, new Vector3(randomPosition.x, randomPosition.y, 0f), Quaternion.identity);
        }
    }

Hi, I have this code for instantiating objects in a random range. My problem is some objects spawn very close to each other and I'm trying to make them spawn further away from each other. I have a "minDistance" variable that I use with the CheckSphere component but it does not work at all.

They still spawn close to each other sometimes even on top of each other.

[leaden ice]

To help with your research a good technique for this is called Poisson Disc Sampling:
https://www.jasondavies.com/poisson-disc/

you may be able to find an existing unity implementation, or write your own
The reason your CheckSphere code isn't working is because you would need to call Physics.SyncTransforms whenever you add or move a collider before they can be picked up with a CheckSphere.

[topaz plaza]

I have a weird issue.
My selected platform is Android. Play mode works fine with it without any errors or warnings.
However when I want to build the Android APK the following errors occurs (see screenshot)
The errors are related to the Multiplay SDK. The package is installed and I am using it and it works in Playmode. I am not using any ASMDEFs.
The other screenshot shows my build settings.
Any idea why this happens? Can't fix it.

[leaden ice]

You're not using asmdefs but surely the netcode and unity services packages are

are you sure they're all supported on android?

[knotty sun]

we had this problem yesterday with webgl and multiplay, check the asmdef inspector for multiplay

yep, #archived-code-advanced message
not compatible with Android

[modern tinsel]

Thanks I'll investigate further

[topaz plaza]

Ah ok so I have to exclude the server script on Android build. Which makes sense anyway since the android is Client only

Thanks for the info. Lucky I just stumbled over it today

[neon plank]

That property gives angles from 0 to 360. I would like to have values from -180 to 180. What could I do? This are angles, so I doubt I could just do -180 to change the range.

[late lion]

You can subtract numbers that are greater than 180 by 360.

[neon plank]

Ok, I will try. Thanks

[hidden flicker]

What's the best way to go about adding mantling? Basically, if a player runs into a wall and they are close enough to the top of that wall, they snap on top of it. A bit lost on how to do this

[hard viper]

are you in 3D?

and are you working with actual walls, or stairs?

the KCC has very good support for stairs in 3D, which is the hard-as-shit case

[hard viper]

alternatively, are you in 2D working with walls?

as in grabbing ledges

[hidden flicker]

i'm in 3d, and using a physics based character. this should work with things other than walls as well, and be an instant process. not an animation.

[hard viper]

ok, so, I would break this up into a few different problems.

1. getting a contact for touching a wall,
2. determine if that contact is valid to allow snapping up,
3. given a valid contact point, compute the spot where you would end up
4. given where you end up, check if that movement is valid.

is there one of these 4 in particular you find more challenging?

[hidden flicker]

2, 3, and 4

1 is fine. i can just do it oncollision enter or with a small raycast

[hidden flicker]

this is my current playerscript btw, if that helps. yes ik it sucks. it's what i'm working with for now
https://hastebin.com/share/ihihokodav.csharp

[hard viper]

let’s just focus on the problem at hand

2. now you have a contact, and want to know if it is valid. You need to check a few things:
   -Contact normal must be in a good direction towards player.
   -The thing you are contacting allows you to snap up (eg ground layer or something).
   -Player facing direction is oriented towards contact point (probably? unless you want to snap up while walking backwards into a wall)

i would make a separate script for all of this btw

3. Now we know that the contact MIGHT allow us to snap up. So we need to find the relevant spot we would end up. I’m not super familiar with the 3D physics queries, but you need a method that lets you find a point between two points on a collider. Specifically, you need to search between contact point and contactpoint + some max snapping vector. We’re searching for the wall’s ceiling (potential new floor). From here, we can calculate the point our player would be at.

If no valid point is found on the collider, then cancel

4. now we know where we would end up if we did snap. First, we need to check that area. Again, we need 3D physics queries, but we’re basically looking for an OvelapCollider method. Somethinng where; If the new spot would have us colliding with a wall/ceiling etc, cancel

make sense?

[hidden flicker]

pretty sure, yeah.

[hard viper]

check the Collider3D and Physics classes for relevant methods.

[hidden flicker]

perfect, tysfm

also, if you have the time and want to, do you have any quick tips for level design? i know a lot about combat arenas, balancing, enemy positioning, functional stuff, etc, but do you have any advice for how to make an area feel distinct and memorable? (i saw you have level designer in your profile, that's why i asked)

[jaunty iris]

hello am trying to make a player pref that i can change the name in the editor but i have no idea how to do this:Exsample
public string Key;
PlayerPrefs.SetInt(Key, 10);

[deft timber]

so what is the issue exactly?

PlayerPrefs.SetString(playerNameKey, playerActualName)

[jaunty iris]

i dont now how to change the name in of the player pref whit a string in the editor

[deft timber]

how to change the name of the player pref in a editor?

do you know how player prefs work?

you can change the player's name, set it in the player prefs

then you can read it whenever you want

[wicked wagon]

which one would be better to use?
I feel like I should go with the second one since it has seperate InputManager class and more organized. But it handles movement every frame.
In the first one it only moves if there is an input.

https://goonlinetools.com/snapshot/code/#z02iwk7r88n9kd4cuz0mzl
or
https://goonlinetools.com/snapshot/code/#nrpju7u0itx719lcigvlb

[deft timber]

InputManager is better approach

as it gives you more contorl

and it's better in terms of single-resnposnbililty rule

[jaunty iris]

the point is that i dont want the player prefs to have the same name i want them to be different so the most logical think to do is to change the name of the player prefs but to change it i want that to happen via string in the editor

[wicked wagon]

Yeah thought so, thank you

[deft timber]

seems like you don't understand how player prefs work

in player prefs you can STORE certain data

and ACCESS it

you have player name, you can save it in the players pref under a certain key

and then retrieve the name by that key

if you have the name in a variable, you can save it under any key

[spring creek]

It seems kinda like playerprefs may not be exactly what you want too. Have you looked into more robust save methods, like using JSON, or Binary

[jaunty iris]

oK am going to tell you in the most simple way possible i want to save a number but this number needs to be stored whit in different keys so i want to have the posibility to change the name so i dont have to make 1milion player prefs to save the same thing

[jaunty iris]

i want to store a simple number is not that complex

[deft timber]

you want to save the same number

but under different keys?

[jaunty iris]

yes

[deft timber]

why?

[spring creek]

I would still recommend anything over playerprefs. But it's your choice

[somber tapir]

what is not working with this?

[deft timber]

i think you just don't understand properly how player prefs works

[knotty sun]

this statement makes no sense

[deft timber]

it doesn't

[deft timber]

@jaunty iris

why would you store the same number in 100 different keys for example?

i imagine you are making some kind of multiplayer game with X players

and want to save each player name in a player prefs?

no okay it's not the case

since you want to save the same value under different keys

then honestly i have no idea why would you need to make such a thing

[jaunty iris]

can you just tell my how to do it

[deft timber]

but i can't understand your english im sorry

i don't even know what are you trying to do

[jaunty iris]

why do i have to tell you

[knotty sun]

no, explain exactly what you want to do and why you want to do it, I have a feeling this is a typical X Y problem

[deft timber]

then how can i help you?

wtf

[dusk apex]

They did not understand your original question and are asking you to explain better.

[dusk apex]

My interpretation: I want many keys with the same value but I don't want many keys.

[jaunty iris]

I TOLD YOU I JUST WANT TO NAME THE KEYS IN THE EDITOR IS IT THAT HARD TO ANSWERE just dont say anything

[deft timber]

🤡

what does "naming keys in the editor" even mean

[spring creek]

Then do that. I don't know what it means, but go for it

[somber tapir]

what is wrong with the code you posted earlier?

[jaunty iris]

ok bye bye you can`t help

[deft timber]

bye bye 😦

i just think you can't be helped as you can't even specify with proper english what do you actually want

[somber tapir]

that's pretty much all you need:

public class SomeClass : MonoBehaviour
{
    public string Key;
    
    public void Save()
    {
        PlayerPrefs.SetInt(Key, 10);
    }
}```

[fluid lily]

Is there a way to get your custom InputAtcionMap from an InputActionMap assigned through editor?

[dusk apex]

We're not certain. What if they're wanting to change to key while maintaining the same value and without introducing new entries to the player preferences?

[deft timber]

We will never know what did he want, as he can't properly say it

[fluid lily]

You would have to have a managed version for that. Using stuff like OnValidate and other editor based methods.

[fluid lily]

Abways, anyone know?

[deft timber]

you want to get an InputActionMap from assigned InputActionMap through editor?

doesn't make much sense

[fluid lily]

I want to cast to my custom InputActionMap from the generic InputactionMap that I can assign in editor

[deft timber]

you have a class that inherits from InputActionMap?

[fluid lily]

So I have PlayerActionMap that is generated from my action map, but that doesn't serialize in editor feilds. But I can assign it with InputActionMap, but I can't cast to my generated map from it.

[deft timber]

you won't be able to directly cast it from the InputActionMap to your custom generated map

[fluid lily]

Wait there is a inpput-system specific channel

[deft timber]

yes you might ask there for someone more familiar with it

[gray mural]

Yes. #🖱️┃input-system

[steep herald]

do I have a way to access the name of a scene loaded additively via the scenemanager API?

[polar marten]

you know the scene's name, you added it

[deft timber]

why do you send me this

[polar marten]

https://github.com/Dysman/bgTools-playerPrefsEditor

[polar marten]

my bad

[steep herald]

No, this is for editor related code. I can load multiple scenes during editing time, when I press play, I want to know the name of the active scene

[polar marten]

sometimes discord ui is fuzzy

[steep herald]

Those scenes arent loaded dynamically

Well I guess they are, but not by me

[gray mural]

you don't

[polar marten]

i see. SceneManager.GetActiveScene()

[steep herald]

Yeah, unfortunately it returns the first scene and not anything else beyond that

[deft timber]

you can cache the scene name

when you load it

[steep herald]

I don't

[deft timber]

but you can

[steep herald]

It's added during edit time

[polar marten]

hmm... i don't know what to say. it's the active scene isn't it?

[deft timber]

still, you can

[steep herald]

How so

[polar marten]

the first scene is always the active scene in the editor i guess

[steep herald]

I don't want to manually input if I can avoid it

[polar marten]

are you asking what is the last scene you added?

or some other meaning of active?

[gray mural]

You can just access all the scenes added to the build.

[polar marten]

you can do the last scene, i think it's the last scene in scene manager, the order in the hierarchy matches the order in SceneManager

[gray mural]

So do you want to access the scenes that aren't added to the build?

[steep herald]

Okay, you know how th editor now supports editing multiple scenes simultaneously. Well the first scene you add in the editor will be the one returned by GetActiveScene(). I want the last. There's only 2 at all times for my use case

[steep herald]

No, they're in the build

[gray mural]

I see. You can use SceneManager.GetSceneAt(int)

[leaden ice]

ActiveScene is a special concept and not really that important

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-loadedSceneCount.html is important too

[gray mural]

also SceneManager.sceneCount if needed

[steep herald]

Thank you all. Issue was solved via Scenemanager.getsceneat

[coral kite]

Just a thought but SceneManager.sceneLoaded and SceneManager.sceneUnloaded might also work

[leaden ice]

it will not

those are events

[coral kite]

Right it depends on use case, but when the scene is loaded just store the name?

[gray mural]

yes, it will work, but it's too complicated

if you have to find the names of the scenes, use this instead

int sceneCount = SceneManager.sceneCount;

for (int i = 0; i < sceneCount; i++)
{
    Scene scene = SceneManager.GetSceneAt(i);

    myScenes.Add(scene.name); // assuming myScenes is e.g. List<string>
}

[leaden ice]

You want loadedSceneCount

not sceneCount

[gray mural]

why?

[leaden ice]

because GetSceneAt only operates on loaded scenes

it doesn't operate on scenes that are currently loading or unloading

which are included in sceneCount

[gray mural]

I see, I'm sorry, you're right.

Get the Scene at index in the SceneManager's list of loaded Scenes.

Im trying to make normal touch controls(player look) for a mobile fps game, this thing doesnt work as intended, it works to some extent but you can swiper left to right and it spins out, also sometimes somehow it collides with left touch controls(joystick-movement)```cs
foreach (Touch touch in Input.touches)
{
if (touch.position.x > Screen.width / 2)
{
touching = true;
mouseX = touch.deltaPosition.x * mouseSensitivity + xRecoil;
mouseY = touch.deltaPosition.y * mouseSensitivity + yRecoil;
}
else
{
touching = false;
mouseX = 0;
mouseY = 0;
}
}

xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -40f, 40);

transform.Rotate(Vector3.up, mouseX);
fpsLook.localRotation = Quaternion.Euler(xRotation, 0, 0);```

[dusk apex]

What's the unwanted behavior?

[slow shale]

managed to fix it with chat gpt

[dreamy atlas]

ObjectScriptableObject inherits from ItemDataScriptableObject
I'm referencing a script that could either be that ObjectScriptableObject or another script, and I want to run this function when it's this one of the two

is there a good way to do this?

[leaden ice]

if (theReference is ObjectScriptableObject oso) {
  oso.Whatever();
}```

However this is kind of an antipattern, if you're doing this there's something wrong with your code architecture in the first place

the point of polymorphism is to not care about the underlying type when dealing with the parent type

[dreamy atlas]

Ah yeah, you're right
The reason for doing it was to check if the item I'm right clicking with is a block (to place) or an item/tool (to use), I guess having a function in the inherited script that's different in the different inheritors would make more sense

[latent latch]

Ideally you'd have like a single Use() method

[leaden ice]

Or abstract properties on the base class like public bool IsPlaceable / public bool IsUsable

[latent latch]

but I wouldn't bite too hard by type comparison

unless you're checking more than a few types that is

[jagged snow]

    {
        switch (nextState)
        {
            case AiState.Fight:
                yield return fight (target); // I DO NOT WANT THIS TO EXTEND PAST HERE
                break;
        }
        _state = AiState.None;
    }```

Is there a way to stop the couroutine within the fight coroutine? I have a condition thats met in this coroutine but when I do yield break it comes back here, is there a way to have it not return here after fight is done?

[leaden ice]

yield break; exits the coroutine

[hard viper]

the moment you yield break, it is over

[leaden ice]

if you want to just "fire and forget" the fight coroutine and quit this one immediately without waiting for it to finish, you can do this:

StartCoroutine(fight(target));
yield break;```

[hard viper]

you could also just run the coroutine in it

like IEnumerator fight = fight(target);
while (fight.MoveNext())
yield return fight.Current;

[leaden ice]

I mean... sure but that's identical to yield return fight(target);

[hard viper]

i’m just mentioning identical options

so he gets the concept of how they string together

[jagged snow]

To make it clear let me explain what this is actually doing:

    {

        float minAngle = 5;
        while (HasSight())
        {
            float angle = AiCalculations.IsFacingTarget(transform, target);
            if (angle < minAngle)
            {
                Action.Invoke()//This leads to next function
            }
            yield return null;
        }
    }```

```    public void EnterState(AiState nextState, Transform target)
    {

        if (_stateCr != null)
        {
            StopCoroutine(_stateCr);
        }
        _state = nextState;
        _stateCr = StartCoroutine(HandleNextState(nextState, target));
    }```

Pretty much the action will lead to this function which should in theory end the previous ienumerator.
However that loop just keeps on running for some reason it wont stop..

[hard viper]

given that you probably really want to make sure fight coroutine is only ever running one at a time (probably?), I would use Praetor’s method, and store a fightCoroutine variable, where you check if it is null

[leaden ice]

Pretty much the action will lead to this function which should in theory end the previous ienumerator.
Huh?

I don't see what this has to do with the previous code you posted.

and also have no idea what that sentence means

or what Engage has to do with EnterState

[jagged snow]

I'm looking for a way to stop the iterator completely, i edited the code out to make it easier to read.

[leaden ice]

yield break; stops it completely

if you run StartCoroutine(HandleNextState(nextState, target)) again it will run again, naturally

[hard viper]

the iterator stops itself with yield break. Other code can stop it from StopCoroutine, but that only stops the call from beginning next time coroutines are run

like, if the coroutine calls other code that eventually calls StopCoroutine on it… it’s still running until it hits the next yield

[jagged snow]

ill try yield break again, maybe the structure is wrong

[leaden ice]

This all seems very complicated, so you're likely getting lost in the weeds

probably getting confused between multiple running instances of the coroutine

[hard viper]

IEnumerators are great once you get the idea

[leaden ice]

I think I'm kinda confused as to whuy HandleNextState is a coroutine at all?

[jagged snow]

    {
        _pathfinder.SetVelocity(Vector3.zero);
        float minAngle = 5;
        while (HasSight())
        {
            float angle = AiCalculations.IsFacingTarget(transform, target);
            if (angle < minAngle)
            {
                OnActionRequest.Invoke(this,aiAction);
            }
            Vector3 lookDirection = target.position - transform.position;
            _pathfinder.SetRotation(Quaternion.Lerp(transform.rotation, Quaternion.LookRotation(lookDirection), Mathf.Clamp01(1 * _lerpSpeed)));
            yield return null;
        }
    }```
Heres the unedited version. The Event here is to ask the AiMaster if this enemy can attack

[leaden ice]

The code you showed above was HandleNextState

[jagged snow]

This is because it's called from an Ai Manager rather than its own script

[leaden ice]

It's unclear to me which coroutine you want to stop

[jagged snow]

The engage coroutine

    {
        switch (nextState)
        {
            case AiState.Move:
                yield return _pathfinder.MoveToTargetPosition(target.position, 2);
                break;
            case AiState.Engage:
                yield return Engage(_attack1, target);
                break;
            case AiState.Fight:
                yield return Fight(target, _attackIndex);
                break;
            case AiState.Dying:
                yield return Die();
                break;

        }
        _state = AiState.None;
    }```

[leaden ice]

The problem is you're doing this:

        _stateCr = StartCoroutine(HandleNextState(nextState, target));

So when you do StopCoroutine(_stateCr) it's not the actual state coroutine you're stopping

it's the HandleNextState one

[jagged snow]

oh

[leaden ice]

which isn't actually doing anything in the first place

Is there a reason HandleNextState is a coroutine

I feel like what you actually wanted to do was this:

[jagged snow]

I thought it involved whatever coroutine its working on atm

[leaden ice]

    private IEnumerator HandleNextState(AiState nextState, Transform target)
    {
        switch (nextState)
        {
            case AiState.Move:
                
return _pathfinder.MoveToTargetPosition(target.position, 2);
                break;
            case AiState.Engage:
                return Engage(_attack1, target);
                break;
            case AiState.Fight:
                return Fight(target, _attackIndex);
                break;
            case AiState.Dying:
                return Die();

        }
        _state = AiState.None;
        return null;
    }```

[jagged snow]

Yea its a coroutine because i thought doing StopCoroutine(_stateCr) would allow me to stop whatever coroutine its currently using at the time, whether it be fihgt move etc

[leaden ice]

no

DO this

_stateCr = HandleNextState(nextState, target);```

you don't want it to actually BE a coroutine

[jagged snow]

ahhh

i see

[leaden ice]

er wait

scrathc that part

you do want to start the coroutine

[leaden ice]

you just need to do this

[jagged snow]

I'm getting these unreachable code detected here

[leaden ice]

you're missing the return null; at the bottom

read the error

[jagged snow]

ahh

[leaden ice]

then do this outside:

IEnumerator coroutineToRun = HandleNextState(whatever);
if (coroutineToRun != null) _stateCrt = StartCoroutine(coroutineToRun);```

[quartz folio]

Also, those breaks are not reachable because you return directly before them

[jagged snow]

So IENumerator is the specific function inside the class where as coroutine is an instance of the function

im trying it now

[leaden ice]

Not really. IEnumerator is the interface Unity uses to build coroutines on top of

[jagged snow]

    {
        switch (nextState)
        {
            case AiState.Move:
                return _pathfinder.MoveToTargetPosition(target.position, 2);
            case AiState.Engage:
                return Engage(_attack1, target);
            case AiState.Fight:
                return Fight(target, _attackIndex);
            case AiState.Dying:
                return Die();
        }
        _state = AiState.None;
        return null;
    }```

[rigid island]

so are those IEnumerator methods? like Die()?

[jagged snow]

yea so basically they are a way to sequence everyting, the ai master detects when the AI is in a none state to process its next action. As for the Die ienumerator that also has an event at the end to say the animatino has completed then the ai master will then remove the object from the scene via fade or whatever

[jagged snow]

So with this one its not returning from the IEnumerator once its done, is this intentional?

    {
        _pathfinder.SetVelocity(Vector3.zero);
        float minAngle = 5;
        while (HasSight())
        {
            float angle = AiCalculations.IsFacingTarget(transform, target);
            if (angle < minAngle)
            {
                yield return Fight(target, _attackIndex);
                break;
            }
            Vector3 lookDirection = target.position - transform.position;
            _pathfinder.SetRotation(Quaternion.Lerp(transform.rotation, Quaternion.LookRotation(lookDirection), Mathf.Clamp01(1 * _lerpSpeed)));
            yield return null;
        }
    }```
I ended up going with this
```            if (angle < minAngle)
            {
                yield return Fight(target, _attackIndex);
                break;
            }```

[leaden ice]

Well if the loop never ends it will never return

[dark moat]

guys I am new to unity and I need to start working with the grid components . but all the documents I read are like stuff that is flying over my head . so is there any documentation that could make these concepts in unity easy to understand. also I don't like watching YouTube videos as I feel those would limit me in what I can do .
do refer me some good documentations for reference please.

[cosmic rain]

Unity manual.🤷‍♂️
If stuff is flying over your head, you probably miss some more basic understanding, so get back to the basics.

[terse turtle]

Why is this called twice? ```cs private void OnTriggerExit2D(Collider2D collision) {
int notProtectedDamage = attackDamage;
int protectedDamage = notProtectedDamage - 1;

    if (!Attack_Player.instance.isProtected) {
        Player_Stats.instance.health -= notProtectedDamage;

    }
    if (Attack_Player.instance.isProtected && collision) {
        Player_Stats.instance.health -= protectedDamage;
        stats.health -= 1;
    }
}```

[spring creek]

Debug the collision to get the name of the gameobject

[terse turtle]

I think I know. I forgot I have two colldiers on the object. 🤦‍♂️. How can I add collision in the "if" statement?

[terse turtle]

This code is a child of an object that also has a collider. This object (Child) has its own collider as well*

[spring creek]

if (collision.gameObject.CompareTag("Something"))

Is a good check

Or

if (collision.gameObject.TryGetComponent(out SomeScript script))

But yeah, you'll want to check what object is triggering it somehow

[terse turtle]

It is called on the player and the object? This object is an enemy

[spring creek]

I'm not sure. Is that the debug showing the names above? So _Player 1 and Attack Pos?

[terse turtle]

Yes, I used print(collision.name)

[spring creek]

You just need to check what you're colliding with
#archived-code-general message

Validate the data before using it

[terse turtle]

Your correct. Its the Player that the enemy is colliding with. The player also has two colliders and those names are of the player

Is there a way not to use Compare Tag?

[spring creek]

Yeah, the second one I showed is good

[terse turtle]

I didn't see that. Thanks

[spring creek]

You can also check the layer

[terse turtle]

Another question: Are you familar with AI movement using the Navigation System?

[spring creek]

Somewhat. You mean the one in Unity itself right?

[terse turtle]

I think so

I have an issue understanding how I can tell the enemy to stop and attack. Currently it stops when its close to the player and attacks, but when the player moves a little away, it starts moving again.

This is the code ```cs void MoveAndFlipAnimation() {
bool isAliveandCanFollow = movementScript.canFollow && !stats.isDead;
bool attackIfPossible = movementScript.canFollow && movementScript.agent.velocity == Vector3.zero;

    if (isAliveandCanFollow) {
        if (attackIfPossible) {
            ChangeAnimationState(Attack_Skeleton);
        }
        else {
            ChangeAnimationState(Run_Skeleton);
        }
    } else if (!stats.isDead) {
        ChangeAnimationState(Idle_Skeleton);
    } 
}```

[spring creek]

Well, you're gonna just have to play with stop distances and attack range. Make the attack range large enough compared to stop range so they can be guaranteed a hit even if they start moving. For example stop within .01, bit attack at .5 or something.

Or you can go the route of attacks hitting even if they move before the animation of the attack completes. Like as soon as they stop it goes through

[terse turtle]

I don't think I explained what I needed. I want the Enemy not to follow the player mid attack. I want it to wait until the attack animation is done.

[spring creek]

Ohh, gotcha.
Either look into animation events (send an event when the animation completes, and halt movement until that is received)
Or use coroutines where you disable movement, yield return WaitForSeconds or until something, then enable movement again

[terse turtle]

THANK YOU! I totally forgot how useful an animation can be. All I needed to do was go to the Attack animation and start record. Then I just checked off the movement script at the start of the animation, and a bit before it ended. (Even though I can't really adjust attack speed, etc this is all I needed)

[polar marten]

what kind of game are you making?

and what is your prior experience programming?

[earnest gazelle]

I have around 500-1000 particles. Their positions are known and given. I create particles (using pool system) and play them but now, I would like a better more efficient way. Can I use just one particle system and give it some points to play instead of playing N different particles ( particle system)?

[craggy veldt]

Pooling for this sort of scenario wouldnt benefit much, instead gpu instanced them

Is this unitys particle system or your own?

[earnest gazelle]

yes, particle system unity.

I don't want to use ECS unless I have to do it

I think particle system has an api to give points and then plays it

[fluid siren]

i get null reference in my code , i try to find the problem and am sure everything fine , it only work when i delete the prefab and put is in the game again , and even after i solve it like this after a while it give me null reference again

[lean sail]

look at the line it is telling u

[narrow yoke]

What is "field.setValue(null, cvar) in this case that the first param is null?

[lean sail]

https://learn.microsoft.com/en-us/dotnet/api/system.reflection.fieldinfo.setvalue?view=net-8.0#system-reflection-fieldinfo-setvalue(system-object-system-object-system-reflection-bindingflags-system-reflection-binder-system-globalization-cultureinfo)

The object whose field value will be set.
I assume its some static field

[fluid siren]

i look am sure the code fine , as i said it for some reason it work again if i delete the object prefab and put it again in the game without changing the code or the references

[lean sail]

you can be sure all you like, you have errors and the code is telling you it. If you're absolutely sure the code isnt the issue, why ask in a code channel

[fluid siren]

where else i should ask my problem then ? guide me : )

[lean sail]

you should post your !code and let someone help you to know why something is null

What do you mean just one particle system?

I'm expecting a particle manager. And it creates its own particle pools.

You make a new particle manager object whenever necessary.

I have a strange error. I Use the System.IO.Directory.CreateDirectory to create folders and it seems to work great.
However in certain programs (Houdini) when looking att the filepaths there is a little wierd symbol at the end. Its generally not a problem
but recently we had to upload a bunch of files and directories for farm rendering and then this little sucker made it inpossible.
In windows, untiy and most other places the symbol doesnt show.
It looks like this:

sorry for the bad resolution, its kind of like a questionmark within a circle

Hello Unity Developers, I have a critical issue in getting stream of event in device using Particle.io.

https://api.particle.io/v1/devices/events?access_token=6f7b7b2528634379f919822304162cafa2ffd481
You can check my api endpoint from the above.
Please help me how to get event data from this api.

[knotty sun]

first thing I would suggest is to use Path.Combine to create your path string

[unborn elm]

Ok

I will look into that, could that be whats causing the problem?

[knotty sun]

it's possible, yes

[unborn elm]

Thank you

Its wierd that i hardly shows anywhere and its just in a very specific program till it comes up

[knotty sun]

it is odd but unfortunately there are many factors which could be causing this so it's best to reduce the potential for error as much as possible

[craggy veldt]

By passing null as the object, we indicate that we're modifying a static field, not an instance field

[native fable]

Hello everyone

I have a question regarding working with assets

I roughly want to do this: for example, build a prototype of a game purely based on primitives (cubes, spheres, etc.)
And then I want to replace the views of these objects in a couple of clicks

Conventionally, how to mark the renderers with some kind of ID in the addresses, store a bunch of assets on your server. with these IDs, and make some kind of storage editor tool in Unity so that you can rip these materials/textures from the server according to IDs and immediately insert them into the components needed according to these IDs

There are 2 questions:

1. perhaps someone has worked in this regard with addressables and can tell you whether this is realistic through them
2. if not addressables, then what is the best way to organize this? There are no problems storing texture materials and other things according to IDs, the question is how to adequately load them into the objects themselves according to IDs

Thanks

[magic herald]

I want a solution to the problem guys

[knotty sun]

The solution is in the error message, just do what it says

[somber nacelle]

the actual solution is to stop using the Standard Assets since they are old and outdated and use the Starter Assets instead

[magic herald]

thank you so much man

[keen solstice]

How helpful are state machines in handling enemy AI?

Or determining of a set of doors are locked/broken into/barricaded...etc?

[dapper schooner]

I am just trying to find out if the Timeline Playable Clips and Track stuff still uses IMGUI or if it supports UITK

In regards to Property Drawers

[grim kiln]

State machines are great for one of these two things, why do you ask?

[simple ridge]

Hi everyone, I posted yesterday about creating a custom collider for recognising when an object comes near a climbable wall, the solution that was found was to use a collision mesh and generating a custom mesh based on the shape of the wall. I have done this now (see the pink shape in the image) however I have noticed now that we can't make triggers from non-convex shapes.

Is there a way around this? If not I will just use a series of box colliders, (with this aswell, is there a way to create box colliders with a rotation property aswell as I would like to avoid creating potentially 1000's of game objects when instead I can have 1 with many colliders on it) If not thats fine but wanted to ask.

[keen solstice]

I realized using Unity's event system would be pretty horrible and clunky when we have different mechanics, because doors need to behave differently when barricaded with different materials, different puzzles need to be 'active' or 'inactive' depending on if they're done, and need to have different 'types' of puzzles displayed depending on what kind of triggers the player has activated

[steady moat]

You could try to use Physics Layer and have your collider non-convex/non-trigger. (Disable interaction between this layer and other. Use Physics querries to find out if you should be climbing)

[simple ridge]

That's a good idea, would querying this each fixed update be faster then just using many other box colliders?

[sick pulsar]

Hey could someone teach me to add .json to my vr game

[hollow inlet]

Why the player animations not work after i created an andoride build

[steady moat]

It would probably be faster to use multiple BoxCollider. That being said, there is a burden in placing those

However, you can still stagger your querry instead of doing it everyframe which could potentially be more performant.

[simple ridge]

Hmm, I'll have a think and will try and implement a debug version for both approaches to see how performance goes! Thanks for the help ^-^

[next sparrow]

Hello everyone. I'm trying to make a third person shooter but I'm having trouble understanding the process to detect a hit. At the moment, I spawn a bullet prefab moving forward using a code found in a tutorial. But this code calculates the end point of the bullet and doesn't check if this bullet collides with something which might have moved in between while the bullet is flying.

I've tried to add a collider enter trigger to destroy the bullet if it is blocked by something but strangely, it still pierces the mesh and keeps going forward until its end.

    private void Update()
    {
        float before = Vector3.Distance(transform.position, targetPosition);

        Vector3 moveDir = (targetPosition - transform.position).normalized;
        float speed = 200f;
        transform.position += moveDir * speed * Time.deltaTime;

        float after = Vector3.Distance(transform.position, targetPosition);

        if (before < after)
            Explode(false);
    }

    private void Explode(bool hitSomething)
    {
        if (hitSomething || explodeOnNoHit)
        {   
            Vector3 moveDir = (targetPosition - transform.position).normalized;
            ParticleSystem ps = Instantiate(sparks, targetPosition, Quaternion.identity);
            ps.transform.LookAt(transform.position + moveDir);
        }
        Destroy(gameObject);
    }

    private void OnTriggerEnter(Collider other)
    {
        if (Config.Layers()[other.gameObject.layer] == "Ground")
            Explode(true);

        PlayerController player = other.GetComponentInParent<PlayerController>();
        if (player != null)
            Explode(true);
    }

Here is my code. I'd like my bulelts to have a max range. If something is hit in between, the bullet expldoes

[leaden ice]

This code in Update doesn't make a lot of sense.

There's a particle explosion when it collides with something

[leaden ice]

Anyway if you want physics interactions you need to move your objects via physics

not with transform.position

You need to use a Rigidbody

give it velocity or add forces to it

[next sparrow]

The tutorial I used said rigidbody is not really reliable when using mutliplayers and I wanted to add this feature later on

[leaden ice]

I have no idea what that means

[next sparrow]

So they gave this code instead

[leaden ice]

moving via the Transform like this means it's going to teleport through objects etc

I think you're way too early in your Unity journey to even dream about multiplayer anyway

not that that statement makes any sense in the first place

[next sparrow]

And the bullet won't teleport the same with a rigibody?

[leaden ice]

Rigidbodies are physically simulated

using the physics engine

they will collide with things realistically etc

[next sparrow]

And physically simulated objects don't behave the same as simply moving the transform?

[leaden ice]

A rigidbody is also required if you want to use OnTriggerEnter or OnCollisionEnter

[leaden ice]

no they do not

they behave according to the rules of physics

[next sparrow]

But aren't those physics rules simulated, meaning it would still be moving the transform in the end ?

[rigid island]

directly moving transforms yourself, is the same as teleporting. Physics run on their own timestep

[next sparrow]

Ah, I see. That does change the logic then. Thanks for clarifying. I'll try with the rigibody then.

[rigid island]

rigidbody ideally says "i slammed in this wall, i cannot proceed" so the transform stops where it needs to

[next sparrow]

Got it. Thanks!

[leaden ice]

Of course but it's better than you doing that physics simulation yourself

okay,

[rocky jackal]

i have a function that takes quite a while with doing a lot of raycasts so i want to do it on a difrent thread, is it still usefull if i need to define this many variables ?

[vagrant drum]

thanks :)

[fervent furnace]

you cant have managed type in job

use command instead

[vagrant drum]

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

[rigid island]

np!

[vagrant drum]

here's the code of my inventory system

[rocky jackal]

whats a managed type ?

[rigid island]

so is the problem only when you switch item or

what is supposed to be happening and what is happening instead ?

[vagrant drum]

yeah. when i pick the ground item and then try to equip another, the ground item is still in my hands

and that's not supposed to happen

i need it to be deactivated

[rigid island]

you have a lot of if statements that need to be throughly checked

many conditions here

sounds like lastOBJ might not be properly setting or something

[vagrant drum]

how can i avoid using so many if

[rigid island]

its not so much the quantity (although avoid nesting by using return statements)

but things like if (index >= 0 && index < items.Count && items[index].itemAdded && items[index].eventHandler != null)

thats a very long if statement

any of those can fail

[vagrant drum]

in the inspector, the lastOBJ is switching properly

[vagrant drum]

got it

[rigid island]

is this supposed to set it inactive. ?

if (handScript.lastOBJ != null && handScript.lastOBJ != items[index].eventHandler)
            {
                handScript.lastOBJ.SetActive(false);
            }```

start using Breakpoints to your advantage

https://unity.huh.how/debugging/debugger

its easier tbh when you visually see what your code is doing

[vagrant drum]

Hmmmm okay

[wise pumice]

public class MovingPlatform : MonoBehaviour
{
    public float speed = 1;
    [SerializeField] GameObject[] waypoints;
    int currentWaypointIndex = 0;
    private Vector3 lastPosition;

    public Vector3 direction => waypoints [currentWaypointIndex].transform.position - transform.position; 

    // Update is called once per frame
    void Update()
    {    
        if (Vector3.Distance(transform.position, waypoints[currentWaypointIndex].transform.position) < .1f)
        {
            currentWaypointIndex ++;
            if (currentWaypointIndex >= waypoints.Length)
            {
                currentWaypointIndex = 0;
            }
        }
        // Move towards
        transform.position = Vector3.MoveTowards(transform.position, waypoints[currentWaypointIndex].transform.position, speed * Time.deltaTime);

        lastPosition = transform.position;

    }
}

Anyone have any idea why this cube of mine just keeps going forever in one direction?

I wanted it to go back and forth between the two waypoints

[somber tapir]

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

[earnest gazelle]

I have the pool system for it but using just one particle system is more efficient.

There are n ripples with specific positions.
I know I can spawn one particle system for each and pool it but having one particle system for all of them and set their positions is my desire

[somber tapir]

Anybody knows why this is possible? Position doesn't have a member called xy. Is this a Unity/ECS thing or a C# thing?

[rigid island]

says it right there Unity.Mathematics

xy is a float2

float3 is a custom struct and it has that xy

there is also xx

[spring creek]

Mathematics is the DOTS math package, yes
You can use it wherever, but that was what it was made for afaik

[somber nacelle]

it's because in this case transform is a LocalTransform whose Position property is a float3 unlike the Transform class which has a position property that is a Vector3

[shut kestrel]

Is HDRP worth it right now or is it better to go with URP still?, i plan to make a project only for computer and not mobile platforms

[somber nacelle]

this is a code channel

[terse turtle]

I recently just learned about instances. How should I correctly use them? I am making an enemy and a bunch of scripts need reference to the main stat script, how will this look like if I needed to grab the stat script from around 5 scripts, of done correctly ?

[leaden ice]

I recently just learned about instances. How should I correctly use them?
This is a very confusing sentence. Are you talking about the singleton pattern with a static field named instance?

Every object in your game is an "instance" technically

[spring creek]

StatScript stats = GetComponent<StatScript>()

?

[terse turtle]

I meant this: Public static StatsScript = instance.

[fervent furnace]

static variable

[spring creek]

So you are talking about a Static Accessor.
But that is not how you would do it

public static StatsScript instance
No equals sign before the name

[leaden ice]

Then you access it with StatsScript.instance;

although what you typed is not really what it looks like

[spring creek]

Look at the singleton page here
https://unity.huh.how/programming/references

[terse turtle]

I understand how to access it. Let me explain my question again: I want to know how can I organize my code well with using it. I once saw a video talking about how using Public variables aren't the best way to do something since changing the variable will affect all the other scripts referencing it. I'm wondering how can I use instances without having this being a problem.

[fervent furnace]

google c# properties

[leaden ice]

Well you should be using a readonly property so nobody can change it anyway.
e.g.

public static StatsScript Instance { get ; private set; }```

[spring creek]

Instance isn't quite the right word here
You're talking about a static variable that happens to be NAMED instance

But note that doing what you said makes it so there is only ONE StatsScript variable in existence. If you want more (like enemies have one, the player does, ets) then this is not a good pattern

If you have more than one actual StatsScript instance, then having that static variable will cause chaos

[terse turtle]

I only have one EnemyStat script. That is the static one that all the other scripts reference.

[spring creek]

The script is not static, a variable is. Right?

So all Enemies share the same stats then?

[terse turtle]

Yes

[fervent furnace]

if the script is static, then you dont need to use singleton, use static class instead
btw i think you need to understand what is static keyword first

[terse turtle]

I'll check out the static keyword*

[spring creek]

Did you read this?
#archived-code-general message

You're just talking about a singleton it sounds like

[terse turtle]

No. Let me do that.

Yes it is a Singleton.

I am having no problem with it, but I already noticed how many scripts I am using Skeleton_Stats in. I have two currently, Attack_Player(on player object), Skeleton_Animations(on enemy).

I just want to know a way I can prevent issues.

[spring creek]

So it sounds like you're wanting a singleton database to grab different stat values from.

That seems reasonable.

What issues are you having?

[prisma yacht]

I'm working on a multiplayer game and I have a reticle as a raw image under the canvas

but the reticle script needs to modify the camera script attached to the player

which worked fine when the game was single player

but now that players are spawned in upon joining the game, I need a way to give the reticle a reference to the player

but not to other players

i'm using mirror

maybe I could give the player prefab a reference to the reticle and then assign its reference from the player script when it spawns?

[terse turtle]

I have code that checks if my player is shielded. If it is then a new animation plays, if the player is shielded the enemy also does less damage. On top of that the player also can't move when shielded.

[terse turtle]

There are a total of three scripts accessing isProtected: Player_Animations(on player), Player_Movement(on player), and Skeleton_Attack(on Enemy). * sorry for the confusion 😅

[heady iris]

I'm using Json.NET to serialize to JSON. I want to make a breaking change to a save format -- I'm completely throwing out the old one, but I want to correctly handle the case where a player has an old save file.

In JavaScript, I've just added a "version" field to the save format, and checked that before loading the save.

But this doesn't work with static types -- the old save file will not decode correctly at all.

How do people deal with this?

I am thinking of adding a version field, and also having a class that just looks like...

[System.Serializable]
public class JustTheVersionNumber
{
  public int version;
}

I'm pretty sure I could deserialize the save file to this class (throwing out almost all of the data)

If I can do that, then I imagine I can just keep the old classes around, and deserialize to the appropriate one based on the version number

[System.Serializable] public class OldSaveFormat { public int money; }
[System.Serializable] public class CurrentSaveFormat { public float money; public float health; }

...and I could write methods that upgrade an old save format to a new save format

I am just curious what other people have done in this situation.

Any idea on how to send invites using unity friends and lobby service

https://docs.unity.com/ugs/en-us/manual/friends/manual/concepts/message
https://docs.unity3d.com/Packages/com.unity.services.friends@1.0/api/Unity.Services.Friends.IMessagingService.html

FIX FOR ANYONE SEARCHING IT UP ON THE SEARCH TAB

    public class MessageFriend
    {
        public string message;
    }

    public async void SendInvite(string memberID)
    {
        MessageFriend message = new MessageFriend() {message = "data" };

        await FriendsService.Instance.MessageAsync(memberID, message);
    }```

and you recive it via

void SubscribeToFriendsEventCallbacks()
{
try
{
FriendsService.Instance.MessageReceived += e =>
{
Debug.Log(e.GetAs<MessageFriend>().message);
//DISPLAYS > "data"
};
}
catch(FriendsServiceException e)
{
Debug.Log(e);
}

so if I have an assembly definition file for my code, and one of the editor scripts in that code requires access to URP, HDRP, or Builtin(whichever one is currently in the project), how do I set up the assembly definition file for that?

[heady iris]

I believe you can just install both the URP and HDRP packages, then add references to the relevant assemblies

It says it'll ignore any missing assembly references.

[rigid island]

you can also use Define Constraints

[zinc parrot]

can I then copy that to my main project(with only builtin in it) and itll keep all references when I export it as a package?

[heady iris]

I'd expect so. Each one will reference an assembly definition asset.

So it'll complain that there are missing references

sounds like navarone knows more than me here, though :p

[rigid island]

I think this
https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html#define-symbols

but idk specifically URP/HDRP but im sure they have their own define

[heady iris]

Here's how Shapes does it

[zinc parrot]

I need all 3 pipeliens available to a specific code file, can this do that? I saw this but I dont see the defines listed anywhere

ooooo ok!

[heady iris]

So all of the packages were installed when it was set up

There's nothing wrong with having both the HDRP and URP packages installed

(all that matters is which SRP asset is selected)

understanding that made me a lot less afraid of messing with render pipelines

[heady iris]

this screenshot is from an HDRP project

[zinc parrot]

thanks!!!

also then is there any way for me to have this influence some #defines in compute shaders when they get compiled?

[heady iris]

not sure on that front

I guess you'd just look at the currently defined symbols normally

[heady iris]

All that this does is tell Unity you'd like this assembly to be able to reference every assembly in that list, if it exists.

Once you have those references, things will behave just like you didn't use an assembly definition at all

[zinc parrot]

awesome! thanks!!

[untold siren]

Random q but does anyone know when the first package for cinemachine ever released?

Hey, I'm working on a 2D mobile game that's close to Rythem games (like Beatstar), there's a a block falling (UI Image), and there's an area that if you time it writes it gives you a streak, I heard that you could use Events to check if the block is still in the area.
Which event is that?

[rigid island]

why not using sprites

idk what event means in this context, it can be anything lol

[spring creek]

When you say events, I assume you mean physics messages
Like OnTriggerEnter and OnTriggerExit

Or just OnTriggerStay would be good enough I guess

Those will need colliders, so you'd want to use sprites as nav said

[sly crag]

I have to use the canvas to make the game (Design wise Resposive)

[spring creek]

Well then you're gonna need to just track positions manually

[sly crag]

And It's so tricky to do that, the Rect Transform behave strangely

[rigid island]

yeah because you wouldn't want to use canvas for this type of gameplay

[sly crag]

What I ment By Events is like IPointerEnterHandler (Interfaces)

[rigid island]

that only tells you if your pointer interacts with UI but not like a keypress

[leaden ice]

Man building your game out of UI is just going to be a bad time

Anyway a proper rhythm game doesn't depend on the visual representation of the objects anyway

[rigid island]

made a whole game with Cards in UI and let me tell ya thats hard as it is, i can't imagine something you need movement.

[leaden ice]

the thing the player sees is just a presentation layer

the best way to do the gameplay is purely in the data model

e.g. you know the note is coming at time n, then it's valid to press the key at n +/- .05

[sly crag]

Is there another way to appropriately scale the game with screen size rather than canvas?

[leaden ice]

the notes on screen are just a visual representation of that

[rigid island]

there is a script somewhere that shrinks/expands sprites according to screensize

[sly crag]

I just know there's a Canvas scale section that help me with that. idk if there's another

[rigid island]

no built in ways for sprite renderer

Hey guys, I've successfully included Unity.Collections as an assembly definition reference and now I can use collections such as the NativeHashSet. However, I still can't use NativeParallelHashSet... how come?

[leaden ice]

What happens when you try?
What does your code look like?
What version of Collections are you using?

[sturdy thorn]

Hi! I need help please!

So, this is my character roster

whenever I press Shift, the present character gets disabled and I control another one

[feral holly]

The usual "CS0246 The type or namespace name 'NativeParallelHashSet<>' could not be found (are you missing a using directive or an assembly reference?)".
Unity 2022 LTS, fresh project with the latest Unity.Collections version of 1.2.4.

public class NewBehaviourScript : MonoBehaviour
{
    NativeHashSet<int> nativeHashSet;
    NativeParallelHashSet<int> nativeParallelHashSet;
}

[sturdy thorn]

its all fine except for the animations

[somber nacelle]

that version of Collections does not include that type

[leaden ice]

NativeParallelHashSet doesn't exist in 1.2.4
That's actually a pretty old version.

[sturdy thorn]

when I change controls while running the disabled script character keeps doing the run anim

[leaden ice]

The latest version of Collections is version 2.4

It kinda depends which Unity version you're using though

[feral holly]

Wait what? I don't see an upgrade button in the package manager o.o

[leaden ice]

What Unity version are you using?

[feral holly]

2022 LTS... :(

Does this mean I have to use Unity 2023?

[feral holly]

No, I shouldn't have!

How can I upgrade the package then? (without an update button)

[leaden ice]

Sometimes the upgrade button isn't there because the package is locked

[feral holly]

Maybe it has to do with my dependencies

[leaden ice]

it might be locked due to compatibility for another package you have

for example Jobs

or something else

[leaden ice]

may be yes

[feral holly]

Alright, thank you very much! You guys were super helpful 😊

We almost forgot about Mclovin!

[feral holly]

What are you using to move to the run animation? Activating a animator boolean? In that case, you might have to turn if off when you switch characters.

[sturdy thorn]

https://pastebin.com/5dn04qZ6

[feral holly]

I'm pretty sure you'd be better off using animator parameters and setting those to true/false instead of calling Animator.Play(stateName)

I'm trying to figure out the SerializeReference attribute

For some reason it doesn't display my enums correctly in the inspector

[leaden ice]

What's shown incorrectly? Transition Type?

oh and Current Type?

[wide dock]

It does display correctly after I edit the array tho

Sometimes it works fine, sometimes it doesn't, honestly I have no idea what exactly makes it behave this way

[latent latch]

enums are buggy in the editor in general if you don't map the first element to a zero value

[wide dock]

From what I can see so far, it happens when I close and re-open the inspector for that specific GameObject

[latent latch]

not sure why that is but it's an annoyance when working with flags sometimes

[wide dock]

Added via button, the enum displays correctly, when edited it turns into an int

when adding another element, it displays correctly again, until I change it again

[wide dock]

They all start at zero

[wide dock]

Is there a way to manually refresh the inspector window?

Closing and re-opening the inspector makes the enums display properly again, so that might help

[latent latch]

Probably in the layout menu

otherwise maybe save/load the layout?

[wide dock]

Oh, by manually I meant via code

[polar marten]

you can set the version in manifest.json

[feral holly]

I removed the packages that needed that specific version of Unity.Collections (I didn't need them). Then I could update it :)
