Any direct way to reference is better than FindObjects

so it comes down to preference and organization between singletons and/or events

[lean sail]

the static event sending a reference to itself would be something id try to get away from. if something just wants to subscribe to a specific instance, and ignore all the other instances, the static event is gonna introduce more complexity. You're gonna have to know which instance you want anyways
But if you simply want to be notified of something happening with every single instance then i guess it works

although ive never needed such a thing

[runic linden]

Appreciate the feedback. Since I have no formal education in programming I am often unsure how much pain my programming choices wil bring in the long run 😄

[signal wadi]

So out of interest how do static Actions replace the need for FindObjectsOf<Type>

[twilit scaffold]

Every time i change/populate a value here(SerializedFields), the domain reloads. Is this an issue, or is this expected behavior? i am using 2022.3.26

I just do not recall it doing this, up until now, in other projects. seems to be doing it everywhere now though

[mossy snow]

you cropped it out, but you're probably modifying the default values for a MonoScript so yes working as intended. Hopefully you don't think you're editing prefabs

[twilit scaffold]

I am just populating serialized fields in the inspector.

[runic linden]

Its not 100% equivalent but in my case I just need the most recent safe area that my character traversed. So I could either:
a) cache all safeareas and then subscribe to each scripts own Action or
b) cache no reference and listen to the static Action that adds the most recent safearea as a reference.

Even though theoreticall you could call the static Action on Awake() on each safearea to get the all references. Sounds horrible though. 😄

[mossy snow]

technically you're populating default references for a MonoScript, which is what the MonoScript's serialized fields will be set to by default when you add it to a GameObject in the editor

[twilit scaffold]

Is there a way to set them to default in the code ahead of time? Without a Find/Set, etc. i mean more similar to float imAName= 2.0f; Basically, is there anyway to stop it from reloading the domain every time i set a serialized field value. Or, set is ahead of time in code so it only has to do it once as a group

[mossy snow]

you're not setting any serialized fields atm. You are setting default fields. You probably mean to create a prefab and edit its serialized fields, in which case you are doing it wrong and that's why it feels weird to you

[twilit scaffold]

Oh, **** Yes. thank you. Major brain dead moment. sorry you had to say that three times before it registered

[vague tundra]

This is a weird question so I apologize in advance if it bothers anyone.
I've never gotten far enough into developing a game to need to utilize Scenes.
I always thought the rule was "1 scene at a time", but after looking into it, I see that scenes seem to be just a collection of GameObjects, such that multiple scenes can exist in the one "World" at a time.

My question is, is Unity setup in such a way that there is always only ever exactly one "World"/"Universe" and we load/unload scenes into and out of it?
(The answer may be very obvious and justifable, but I'm more interested in any discussion that comes from asking)

[final fox]

Hello, I'm trying to create a wall-sliding mechanic for my character. To do so, I've created a minimal environment with just a ground tile and 2 walls to test it. I have written a script for the mechanic myself, however, the character just sticks to the wall instead of sliding. To fix that, I looked up a tutorial on YouTube which writes a completely different script for the wall-sliding mechanic. So I created a new project, created the same minimal environment, and copied the script from Youtube into it. The result is however the same, the character is just sticking to the wall instead of sliding off.

I can attach both scripts here, however, I'm starting to think it might not be a coding problem. But If it isn't, I don't know what else it could be since it doesn't seem like i'm doing anything wrong in the scene.

[vague tundra]

Checked the following?:
Rigid-bodies gravity
Physics Materials

[final fox]

Yes, all in order

Rigidbody & Box collider for the player,

Box colider & Wall layer for the walls

Ground layer & Box Collider for the Ground

[vague tundra]

Check the players position when they're on the wall. Is the position completely constant, or changing infinitesimally?
(Just throwing some sanity-checks at ya)

[final fox]

I did, it's actually changing sometimes, it will very slowly fall , but it takes breaks if you know what I mean? It will slide for 0.0002 for 2 seconds then stop for 0.5 seconds then keep going. The speed of the sliding changes if I increase the gravity scale of the character, however it remains inconsistent.

[vague tundra]

Interesting.
And you've added physics materials (since ur using Physics by the sounds of it) with the appropriate friction?
Might be worth testing with a frictionless material

Additionally, change whatever your players move speed is to some massive value and see if that shoots him off into space, or if he's really stuck in there (not too massive tho haha)

[final fox]

Booting up the project now to test that

[vague tundra]

I can't promise anything but shoot your script through and I'll have a look, if the tests yeild no fruits

[final fox]

What physics materials are you talking about? Honestly I was under the impression that physics are innate once you add the rigidbody + box collider

Also nothing changes no matter what modifications I make here

^^^ Wall Layer is set to Wall btw

[vague tundra]

You should be able to create a Physics Material and provide it to the RigidBody component of both the player and wall

Right-click in Assets or whatever, and select Physics Material, I think

[lunar python]

how come your player controller don't have 100 lines of serializable

[final fox]

I have a 2nd script that does have that haha

I was testing with 2 different scripts

[final fox]

can't find it give me a minute

[lethal solar]

So I'm new to Unity, and running into an issue that I'm not sure how to solve.
The view area for my player is the selected box here - the chat-like panel on the right side shouldn't have anything render under it, so I want to constrain the camera's render area specifically to the currently selected box.
I'm not sure how to do this exactly - I feel like using a render texture would have downsides? (click raycasts for selecting things not working? not sure if that's an issue to be concerned about or not).
But I'm otherwise not certain about how to deal with this issue.

[final fox]

I found an easier way of checking for ground/walls other than creating an empty game object by creating an invisibile ray around the character that checks for certain tags, i'll show you in a second

[lunar python]

if you are using 2d, you can click on 2d then physics materials

[final fox]

yea ok found it

[lunar python]

yes I know you can use OnCollisionEnter but im too lazy to change it

[pastel marsh]

i am making a tic tac toe game and i want to make it single-player
how can i add AI moves to it?

[final fox]

I've added the physics to the wall/player, played with the numbers, now the player just completely sticks to the wall

nvm ^^ it still slides slightly

[vague tundra]

Interesting, with 0 friction?

Feel free to paste your script

[final fox]

Yeah

Yo

it works now

wait

let me figure out what i just did

So, with friction 0, it doesn't stick to the wall, but it also doesn't slide, with anything > 0, it will just stick to the wall, so ig the problem isn't solved

[vague tundra]

Vector2 raycastDirection = transform.localScale.x > 0 ? Vector2.right : Vector2.left;
localScale? Oh, does that 'flip' 2D things?

[final fox]

Yes

its for the ray i was talking about

[final fox]

But I think there might be a problem with it now

For some reason now the wall slide works properly for the first time ever

Howevr it only works on the right wall, and there is no difference between them. But I think I can fix that

[vague tundra]

Sweet, sounds like you've found something to investigate. Goodluck friend

[final fox]

Thank you, couldn't have done it without your physics suggestion, honestly I thought that was mainly a 3D thing, still got a lot to learn about Unity

[soft shard]

You would probably need some kind of director or state machine that can determine available spots based on whats on the board already, depending on how challenging you wanna make the AI, you could have it pick a spot at random, or "score" spots similar to A* pathfinding logic (MinMaxing) and pick the spot with the highest score, though that could have a lot of games end in ties against players who are familiar with the rules of Tic Tac Toe, though there are probably more simple approaches online searching something like "tic tac toe ai C#" or "tic tac toe ai algorithm tutorial"

[pastel marsh]

ok i will try that

[real anvil]

TicTacToe has a lookup table for the most optimal move

i.e unless you dumb down your AI your games will always be a draw

[pastel marsh]

i think then itll be better to have two types, one which selects randomly and one with minimax

[sweet swift]

Can someone help me? I am working on an Android multiplayer game project, and I am experiencing stuttering while playing the game. Is there any solution to fix this?

[lean sail]

it always being a draw is incorrect. tictactoe is solved, if the AI goes first it can always win. maybe just have a random chance for it to select a random square (unless there is a direct win), otherwise it tries to minmax.

[real anvil]

You're in the editor, not really a true performance test though your CPU time seems very high

Tris are fine, so your GPU isn't the bottleneck

Probably too much garbage being generated

Open the profiler and see

Window > Analysis > Profiler I think

I reckon it's GC issues

[opaque sinew]

hi My problem concerns the rotation of my camera in my first-person game. When I switch to a second camera, I find that my camera doesn't rotate properly. I'd like my second camera to be able to change direction like the first

[runic venture]

nvm prolly wrong channel

[sweet swift]

i just created a new project and tested the third person controller still i am experiencing the stutter

[real anvil]

Whats in the third person controller

The update loop specifically

The best way is to profile it

(and on device rather than editor)

[sweet swift]

The same stutter also occurs on the device

[lean sail]

You should use the profiler to see what part is actually causing a stutter, which I assume you're referring to a drop in fps since the video really didnt seem like its stuttering.

[real anvil]

Before we can actually help you need to show a screenshot of the profiler or post your update loop

If you have narrowed it to your third person controller

My GameObject 'i' is gets destroyed occasionally which isn't the problem. But the problem is I face missing reference exception. For which I have added if (i != null), but this causes the unity engine to be freeze and gets in infinite loop ig

[knotty sun]

a problem is here

items.Remove(i);

you cannot remove from the source of a foreach. You need to use a plain backwards for loop

[fervent furnace]

you cant modify collection is foreach

[frail dust]

for (int i = item[max]; i > -1 ; i --)

u mean this?

[knotty sun]

Also there is abasolutely no point is just butting ou8t text messages in your debugs, include some variable data so you know what is going on

[knotty sun]

items.Length or Count, but yes

[frail dust]

okayyyy

[knotty sun]

i >= 0

[frail dust]

yeah

also Destroy(i) is correct?

[fervent furnace]

i is int

[knotty sun]

you will need some thing like

GameObject go = items[i];

then replace all i references with go

this is definitely not Code General territory

[frail dust]

got it

beginner code question

these are very much beginners questions

how would ik that this is a beginner question tho

thanks anyways

[unique delta]

i m getting this error Random' is an ambiguous reference between 'UnityEngine.Random' and 'System.Random' at this line "float randomnum = Random.Range(0f, 90f);" i made this a half year ago and only now it gives me this error

[thick terrace]

put using Random = UnityEngine.Random at the top of your file to fix that

[acoustic laurel]

is dashing just a player sliding really quick across the world grid with cool animation?

[unique delta]

is really not working

[thick terrace]

unfortunately i can't help if you don't give any more info lol

[unique delta]

A 'using namespace' directive can only be applied to namespaces; 'Random' is a type not a namespace. Consider a 'using static' directive instea

[fervent furnace]

the syntax of using XX=AA.BB.XX is using alias not using namespace
show your code

[unique delta]

i figured it out thanks

[keen forge]

hey guys, have a problem. I started making settings screen in my game and want to provide standart set of settings for player. The problem is
Screen.SetResolution(640, 480, FullScreenMode.ExclusiveFullScreen, new RefreshRate() { numerator = 60, denominator = 1 });
This function literally does nothing. It just doesnt changes resolution. I know that is shouldnt work in editor, so i test it in build. I tried few versions of unity and it doesnt helped.

[leaden ice]

Are you sure the code is actually running?

Have you verified it with logs?

[keen forge]

yep

[thick terrace]

you should generally only set the resolution to one you know is supported by the screen, you can fetch those from https://docs.unity3d.com/ScriptReference/Screen-resolutions.html

the supported refresh rate might be slightly different for example

aside from that, have you looked at the logs from a build?

[keen forge]

Oh, actually code was running in editor, but not in build, your question helped me to realise it and i fixed the problem! thx a lot!

[placid summit]

anyone know a good source for geometry maths? I want to know which of 2 lines is most parallel to another which the slope check could do though the slope is infinite as it becomes vertical!

chatgp(mention it not) suggests slope comparison and then struggles with my mention of divide by zero case!

[fervent furnace]

https://en.wikipedia.org/wiki/Dot_product

[leaden ice]

Vector3.Angle or just the dot product

(Dot product will be more efficient but Angle is more understandable)

[placid summit]

yes thanks - dot product is good

[leaden ice]

Just make sure you normalize your vectors before comparing dot products

[placid summit]

I always forget dot product when not doing lighting

[fervent furnace]

advanced:
since the "end point" of every unit direction vector lie on a unit circle (if they are start at origin) that means you can do a nearest neighbor search to get the closest point==closest direction

[placid summit]

true dat

[rough tartan]

Do you know if I can create the name of an instance based on the value of a variable? I'm creating a websocket server for my game and I want to use instances of a "game" object to manage each game in progress, and to differentiate each game I wanted to know if I could name each instance of "game" with its ID which is a value defined by the player .

[leaden ice]

You can do whatever you'd like - but using the names of GameObjects is probably not a great way to do things

You should probably store that information in a custom script instead.

[rough tartan]

What do you mean? Because I want to create a class that manages a game, and then create as many instances of this class as I have games in progress.

[knotty sun]

Do you mean make a Dictionary with the name as key and the " game" object as value

[leaden ice]

Yes that makes sense. So what are you actually asking I guess?

If that's possible? Of course.

[rough tartan]

no I wanted to know what was the best way to access each of these instances? because at first I wanted to give each of the instances a different name using the game ID that the client uses to create the game, but apparently I can't do that, so what should I use, a dictionary? something else?

[leaden ice]

Sure a Dictionary works fine

[rough tartan]

OK, but how do you modify a value in a specific instance, since they'll all have the same name?

[leaden ice]

You can also give them whatever names you'd like, but that in and of itself doesn't particularly help you access them. It depends on what your access patterns will be like. If you'd like to access them by player ID or something then a Dictionary makes a lot of sense

[leaden ice]

the name is irrelevant. You use instance references (which would be stored in the Dictionary)

[knotty sun]

why would they all have the same name if that name is being supplied by the players

do you not know how to use a Dictionary?

[rough tartan]

because apparently I can't use a variable to name an Instance.
i can do :

game = new Game();

but i can't do something like :

GameID = 1
"game"+GameID = new Game();

[leaden ice]

Use a dictionary

myDict[GameID] = new Game();```

[knotty sun]

but you can do

Dictionary{string,Game> games;
...
games.Add(GameID, new Game());

[rough tartan]

Ok I'll look into using a dictionary, thanks for your help!

[knotty sun]

I'm just wondering how you think you were going to create a WebSocket Server without using dictionaries? It seems like this is new to you

[rough tartan]

Yes, I've never really used a dictionary, so I don't really know where and how they can be used because I only learned them in school in python to count the number of different items in a store XD.

[buoyant mural]

Reset() on a ScriptableObject is supposed to be called as soon as it's created and when the reset button is called, but I'm having a problem where it never calls when I create it

#if UNITY_EDITOR
    private void Reset()
    {
        string assetPath = AssetDatabase.GetAssetPath(GetInstanceID());
        string fileName = System.IO.Path.GetFileNameWithoutExtension(assetPath);
        if (string.IsNullOrWhiteSpace(fileName)) return;
        itemName = fileName;
        Debug.Log("i just reset earth");
    }
#endif"```

[rough tartan]

also i'm trying to redo the multiplayer of my game, which was made in php and could only contain one game

[leaden ice]

Put the log at the first line

You have an early return that might be running

[buoyant mural]

oh yea i forget that

oh wait

u just made me realize the mistake

I looked at the return and it's checking the wrong string

thanks bro

Is Awake after or before Reset()?

[leaden ice]

Look at the chart here https://docs.unity3d.com/Manual/ExecutionOrder.html

(before)

[buoyant mural]

Thanks, but I've seen Awake get called again when creating the file and clicking enter(saving it) but the log had [Worker0] in it

It's quite a confusing situation

I'm just trying to make the string itemName become the fileName upon creation and saving

#if UNITY_EDITOR
    private void Awake()
    {
        Debug.Log("Item just created!");
        string assetPath = AssetDatabase.GetAssetPath(GetInstanceID());
        string fileName = System.IO.Path.GetFileNameWithoutExtension(assetPath);
        //if (string.IsNullOrWhiteSpace(itemName)) return;
        itemName = fileName;
        Debug.Log($"And it's been called [{itemName}]");
    }
#endif``` Awake is when I create the item immediately, then when i  give it name and save, it becomes in this state [Worker0]

[leaden ice]

Couldn't you just do itemName = name;?

[buoyant mural]

fileName?

[leaden ice]

no

just name

As in https://docs.unity3d.com/ScriptReference/Object-name.html

isn't that the same as the filename for a ScriptableObject always?

[hexed pecan]

AFAIK yes

[leaden ice]

(in fact, itemName seems kind of redundant since name exists)

You could also just make itemName a property

public string itemName {
  get => name;
  set => name = value;
}```

then you don't need to serialize any extra data or worry about this reset stuff

[buoyant mural]

hmm, it only works as a property for me

"A field initializer can't be Object.Name"

[dusk apex]

Maybe show what you had attempted to do to generate the error.

[buoyant mural]

I tried initializing it as the value

    public string ItemName = name;```

[leaden ice]

That's not correct

[leaden ice]

A property would be written like this

[buoyant mural]

I know

I don't want it to be a property tho

[leaden ice]

Well making it a field gets you back to square one

I guess an understanding of your goal for this might help

[buoyant mural]

yea

[leaden ice]

What's the reason you need it to be a separate field?

[buoyant mural]

I'm trying to make it that as soon as u create an item with a name, the item name gets initalized as that name, sometimes it helps being more effiecent

[leaden ice]

Right but why does it need to be a field and not just a property?

[buoyant mural]

Can that property's value be changed?

[leaden ice]

Of course it can

it has a setter

[buoyant mural]

I never did a property like that before so

[leaden ice]

That's the standard way to make a property

[buoyant mural]

oh yeah ofc it can lol

[dusk apex]

What the purpose of this itemName variable?

[buoyant mural]

It's what's gonna be displayed in the game UI

[leaden ice]

Everything you are saying leads me to believe this is ideal

[buoyant mural]

So how do I make that serialized in the editor ?

[dusk apex]

Not sure what you're intending but the game ui should just be able to access the name property of the reference object.

[leaden ice]

It's already serialized

because name is already part of the SO

[buoyant mural]

I meant the property

[dusk apex]

Are you just trying to make it visible to the inspector?

[leaden ice]

Why do you need the property to be separately serialized

what benefit would that have?

[buoyant mural]

I meant showing it in inspector

[leaden ice]

Well it would be the filename

But if you want to show it in the inspector you could use a custom editor or NaughtAttributes

[buoyant mural]

I do have a custom editor

[leaden ice]

and have a callback that changes the filename

[buoyant mural]

Ok, I fixed everything

[finite ferry]

Sorry for the late reply, but I found a better solution than my super/sub-class structure, so I don't need help with that problem anymore. Thanks anyways!

But you're probably right, if I really wanted that to work I'd most likely need to make a custom inspector (which isn't really worth it).

[buoyant mural]

It's not worth it tbh, I just removed all the initialization thing, it's not even important now that I look at it, it saves a 1 second of typing and I put 2 hours into this

[zinc parrot]

Hey so is there anything I can use that has the read/write performance of a normal array but the ability to manage the memory manually of a native array?

[leaden ice]

https://docs.unity3d.com/ScriptReference/Unity.Collections.NativeArray_1.html ?

[zinc parrot]

yeah thats the native array I am using
the ability to manually manage the memory lifetime is incredibly useful, but it seems to have slower read/write?

[leaden ice]

You're meant to use it within the job system generally

with the burst compiler the access should be quite fast

[zinc parrot]

yeah im using it within a task

[leaden ice]

task != the job system

[zinc parrot]

I know tasks are not jobs but

yeah

tasks were just easy multithreading for me

[leaden ice]

You can always use unsafe C# code

which lets you deal with pointers directly

[fervent furnace]

unsafelist

[zinc parrot]

oh wait really?

[fervent furnace]

no safety check

[zinc parrot]

I didnt know that

[fervent furnace]

btw i didnt brenchmark it with normal c# array (though you cant still use normal c# array in job system), you can test the i/o per seconds by yourself

[zinc parrot]

ok
is there an array alternative to unsafelist?

[fervent furnace]

unsafelist is just a wrapper of pointer+length+capcaity (c++ vector), nothing more than that

[zinc parrot]

ahhh ok

[fervent furnace]

access the element by .ptr[] to bypass the indexer, the indexer is pretty annoying

When I Destroy a (child) game object on an instantiated instance, then instantiate a new instance - the new instance seems to not have the game object... is that normal?

For background - I have a dialog popup that has a "click catcher" that I have to move out of the hierarchy of the dialog (because of raycast catching conflicts with a component in that dialog). When the user clicks on the "click catcher" the dialog destroys itself, along with the click catcher.

When I instantiate another dialog - the new one doesn't have a click catcher.

[leaden ice]

Sounds like you're actually destroying the click catcher on the prefab

[modern creek]

Yeah I'm uh.. not sure how though.. I can paste some code if that's helpful

[leaden ice]

definitely yes

[modern creek]

// screen that instantiates these dialogs
FtueItemRenderer fir = Instantiate(FtueItemRendererPrefab, transform);
fir.Show(...);

// FtueItemRenderer
public void Show(...)
{
 ...
  SimpleCancelDialog.Initialize(Hide); // on pointer down callback = Hide()
  SimpleCancelDialog.transform.SetParent(transform.parent); 
}

private void Hide()
{
...
  UnityEngine.Object.Destroy(SimpleCancelDialog.gameObject);
  UnityEngine.Object.Destroy(gameObject);
}

[leaden ice]

where does SimpleCancelDialog get assigned though?

[modern creek]

SimpleCancelDialog is basically a full screen image with raycasts on that calls the callback in initialize

it's in the prefab

[leaden ice]

and what object is this script on?

and on the screen that creates these prefabs, it's linked to .. the prefab, as usual

little noisy screenshot, sorry - but the "screen" that's instnatiating these is "GameRenderer", and the prefab is under my mouse and .. correctly linked to the prefab

[leaden ice]

SO it's assigned to another prefab?

or it's assigned to an object inside the FtueItemRenderer prefab?

[modern creek]

the latter

[leaden ice]

Why is this necessary?

  UnityEngine.Object.Destroy(SimpleCancelDialog.gameObject);
  UnityEngine.Object.Destroy(gameObject);```
Shouldn't the second line implicitly do the first?

[modern creek]

basically FtueItemRenderer "takes care of itself" and has it's own cancel click catcher thing... but for other reasons, I have to move this click catcher out of the hierarchy (I'm using a 3rd party unmask component which does some kind of messed up things with the unmask)

[leaden ice]

if SimpleCancelDialog is a child of the FtueItemRenderer?

[leaden ice]

I see

[modern creek]

SimpleCancelDialog.gameobject is out of the hierarchy of this object here

since it's been moved to the parent

[leaden ice]

does that happen in Initialize or something

[modern creek]

yeah, in Show()

[leaden ice]

oh right SimpleCancelDialog.transform.SetParent(transform.parent);

it becomes a sibling

[modern creek]

aye

[leaden ice]

I can't tell from the context so far. I would expect that to happen if somewhere FtueItemRendererPrefab gets reassigned

[modern creek]

I can video it if it's confusing.. .there's kind of a lot going on with this hierarchy and prefab and stuff though, I'm trying to pare it down to the minimum reproduceable code

[leaden ice]

maybe that's happening by accident somewhere

[modern creek]

lemme snap a quick vid while I click around a bit.. standby

[twilit scaffold]

None of the Odin type "Custom Inspector" tools seem to support NetworkBehavior I am currently just trying to get a collapsible list of SerializedFields
they have all failed once MonoBehaviour becomes NetworkBehavior

this also includes NaughtyAttributes. Thre is a slight possibility that i messed up my test of NaughtyAttributes, i will test again later, but i am sure the others did not work. the only one i did Not test was Odin, since they have a wacky license agreement. I buy the thing just so they can inform me that i have to pay them a percentage if i make more than X $. I call BS. so, they remain utilized

[modern creek]

So basically - FtueItemRenderer prefab has a "ClickCatcher" GO of with SimpleCancelDialog on it - i instantiate these as little .. you know, full screen FTUE dialog helpers.. any click on it dismisses it. The first one that gets instantiated correctly moves the ClickCatcher up and out of the instantiated item's hierarchy.. then when it's dismissed, both the ClickCatcher and FtueItemRenderer get destroyed.. but when I instantiate the next one (again from the GameRenderer)... this 2nd one doesn't have a ClickCatcher on it..... and I don't know/understand why

I mean, I could have the game renderer "be aware" of the cancel dialog GO and destroy it, but that feels hacky - the game renderer has enough shit going on already (look at all the serialized fields 🤦‍♂️).. even in spite of my best efforts at components that take care of themselves

perhaps I should be using something in https://docs.unity3d.com/ScriptReference/PrefabUtility.html ?

[exotic tartan]

I need some advice with how I should load and unload objects.

I have about 11 zones that I am not able to separate in the hierarchy.
If the player is in zone 1 I only want to load objects in zones 1, 2, and 5.
If the player is in zone 2 I only want to load objects in zones 2, 4, and 7.
etc.

What would be a good way to set this up? I thought about using tags for the objects in each zone, but I think searching objects by tag is laggy.
I also thought about creating a script that searches for every object by tag, then stores the references for later use. This would cause a large amount of lag at the beginning, but should be fine after right?

[leaden ice]

How would tags help at all? If an object is not loaded, it doesn't exist to have a tag.

When you talk about objects being "unloaded", presumably you are talking about either:

• Using the Addressables package to dynamically load objects at runtime
• Using additive scene loading

[devout herald]

tried to add in occlusion culling to my game, all it did was hide everything i couldnt see from behind.
every single wall, any tile that does not have transparency is both occluder and occludee, the parameters are default. both because i dont know what they mean

[leaden ice]

doesn't seem like a code question

(also not sure what the actual question is)

[devout herald]

i dont know where to post this

[leaden ice]

#💻┃unity-talk

[devout herald]

ah alright

[exotic tartan]

I am using the .SetActive(true/false) to "load" and "unload" objects, I am not sure if this is the correct terminology. If the objects had tags I could search for them, then load and unload them when needed.

[spring creek]

You're talking about pooling

You should google object pooling for the common patterns

[exotic tartan]

dude thank you, this is what I am looking for.

[leaden ice]

That does not load or unload anything. Tags are not the way. Just maintain your own list or set of the items as you spawn them.

And yes this is called pooliong

[versed marsh]

how would one go about fixing a rare case like this? the player is stuck between two walls, and obviously can't jump since they're not passing a grounded check. Curious if anyone else has encountered something like this and how they went about solving it.

[crude mortar]

most games just have a "is considered airborne but not actually moving" check + timer (like 5 seconds or so) that respawns them somewhere on the map since it's a rare case, similar to falling out of the map and getting teleported back on somewhere

although some games just actually softlock you and you have to reload from checkpoint / lose / whatever

[versed marsh]

ahh never thought of that, that makes sense. Thanks!

[knotty vessel]

Hey, my game is taking awfully long to load when hitting the play button and is then stuck in the completing domain part.

I tried to profile it but I can not figure out what scrip(s) cause this giga spike 😅

[molten crypt]

How can i make a plane 2 sided in 3d?

Right now you can only see the material on one side of the plane

[soft shard]

To add onto Nephrens point, one game I can think of in particular, Overwatch has a similar check but adds a small amount of directional force so even if you manage to get stuck somewhere, or find a ledge you shouldnt be on, you will eventually "slide" off it when the force adds up, though they may do that more for gameplay reasons than collision limit reasons

[soft shard]

Not sure if itll help, though you can try changing the bottom left from "Timeline" to "Hierarchy" which should let you see the functions stack that may be contributing

[versed marsh]

make a new material and change its render face to "Both"

[molten crypt]

Ohh

[versed marsh]

oh thats an interesting way to do it, im not sure that would work in my specific case since there is really nowhere to slide to, but that definitely does sound like something worth implementing

[molten crypt]

Mine does not have that actually

https://gyazo.com/6935833d4dc7c023b33266a2ac9d9cae

[versed marsh]

ah my mistake, it looks like you're using the standard render pipeline and not URP. I'm not sure how you'd do it in the standard render pipeline

[molten crypt]

gotcha

[dense estuary]

I am using a rigidbody for movement in unity, but the player is sliding down slopes and moving up them super slowly, I have just created a method that detects the platform the player is on, and the angle of the platform. How can I adjust the velocity of the player based on the normal of the platform they are on? I tried rotating the input velocity but that didn't do anything. Here is my code: https://hastebin.com/share/ucekeqataq.java

[topaz ocean]

How expensive are the "TransformDirection" and "InverseTransformDirection" commands? I use them about 4 times in a single fixedupdate for one of my components.

[loud wharf]

Felt curious, is it possible to get the C# sln file and build it?

From script ofc.

[late lion]

Not ridiculously expensive. You'd need a lot of calls to start to notice it.

[mellow hill]

Hey guys, I have a question. It's not a code or Unity related question per-say but I was wondering for those who have worked with databases within Unity, how have you handled the client-server architecture? Right now I have created a WebAPI for my project and while I have Unity hooked up to the WebAPI, the API is using localhost at the moment. I was wondering if there are any free ways of hosting that API/database so perhaps a small team could access the API/database remotely?

[chilly surge]

Cloud platforms offer free tiers, GCP and Oracle Cloud have forever free VPS that's probably going to be sufficient to host your stuffs.

Alternatively, do you really need all of your team to remotely connect to the same backend? If not, have them host it locally on their own machine.

[nova seal]

I need help with a unity problem that I have dm me @everyone

I need help with a unity problem that I have

[spring creek]

That ping does not work, thank goodness, but did you really intend to ping over a hundred thousand people?

Just ask your question

also don't cross post

[mellow hill]

That could actually work and be easier, would you still be able to update the build this way? So for example, adding new data/tables and having that update once the build is released. Or would I need to keep the server database in sync with a local/embedded database?

[chilly surge]

Are you trying to have your devs connect to your production backend during development?

Because uh, that's a terrible idea.

[mellow hill]

That's fair, I can see the implications with that. How would you go about handling that? Would you just have each dev have their local database running on their own local server?

[last island]

Separate dev environment from staging and prod environments

Always

[chilly surge]

Having a deployment guide for each dev to deploy the backend on their own machine is one option

[mellow hill]

Oh for sure, you can have both a testing and production database. That's what I intend to do

[chilly surge]

But containerization like Docker is made to solve this problem, you just build a container and have devs run it.

[last island]

Yeah, make a container that runs the dev environment

Make devs use the container

On production you can use the same bindings, now the app just connects to a prod container

[mellow hill]

Do I have to pay to host the docker container?

[last island]

Nah.

They can run it locally

[mellow hill]

Awesome, I was thinking about a set up like this. This will make things a lot easier. Thanks guys 🙂

[last island]

What the docker container does is help you reduce complexity of development by having it be a packaged self-contained environment that anyone can deploy anywhere regardless of host machine.

No longer "works on my machine"

[chilly surge]

You can think of it as a virtual machine with everything you already set up, and the user just needs to boot it.

[last island]

The cool thing about it is that the app that gets developed can use the exact same API calls because the production container will be the same container, but with a different environment handling whatever is needed on production side of things.

The app is non the wiser

[mellow hill]

I haven't worked with docker but I'm aware of what it does and the benefits but I thought you needed to pay for the hosting. Since I don't then I think that would be an ideal solution. I can run two docker containers for a testing environment and a production environment

[chilly surge]

Not even that, you can just send the Docker file to dev and the dev runs it locally on their own machine, the same machine that's doing their Unity stuff.

[mellow hill]

Awesome, thanks 🙂

[lean sail]

That FromTo rotation looks wrong, is it drawing the correct ray? I would also turn off gravity and handle it manually if doing a custom rb movement

[dense estuary]

The ray its drawing is correct, its straight out from the surface the player is standing on.

Whats wrong with the FromTo rotation?

[lean sail]

that looks like the normal of the slope instead of where the movement should be going as a result of standing on an angle

[dense estuary]

The ray isnt drawing where the movement should be going

[solid slate]

https://hastebin.com/share/enikuzuxiy.csharp why does it stop on first attack, swing 2 and 3 bools are never set to true i followed a tutorial btw

[cosmic rain]

Assuming the code is exactly as in the tutorial, you probably missed something in the animator or inspector setup

[dense estuary]

Here is the ray of the direction the player is currently moving

[solid slate]

the code looks fine?

[neon junco]

Hey, so I was thinking of making a Utility AI for an enemy NPC that executes actions based on probability. It would collect this information using a ray-cast sphere to understand what is around it. So Utility AI would be its brain and the ray-cast sphere would be its eyes. Has anyone dove into this for game development and can share anything that might roadblock me? planning on achieving this using C#.

[dense estuary]

Here is a video of the ray: https://streamable.com/ux8dgj

[cosmic rain]

On the first glance, yeah. I don't know the tutorial, so it's hard to say without investigating the code and the setup thoroughly.

[solid slate]

alr thx

[cosmic rain]

Adding debug logs or stepping through the code with a debugger would help solve the issue. I'd double check that the setup is exactly as in the tutorial first though.

[solid slate]

good idea i will do that

[cosmic rain]

Well, this is a very abstract explanation. There are many way to implement what you described, so it's hard to say anything about roadblocks as well.

[dense estuary]

Applying the method to the velocity directly messes it up quite a lot https://streamable.com/0zudqv

[lean sail]

    velocity.x = Mathf.Lerp(velocity.x, inputVelocity.x, t);
    velocity.z = Mathf.Lerp(velocity.z, inputVelocity.z, t);

you arent considering the y part here, which explains why its going slow upwards. When you rotate the vector you still need to use the vertical

[neon junco]

So the full detail of the use of this:

Enemy NPC walking doing its patrols then when a player comes with in range of the detection sphere or starts shooting at the enemy NPC the NPC would evaluate what it is around it to use as cover or if the area it currently is has the most cover. The AI would first do a probability of it being hit by the player and if its in a high enough range it checks the better cover in its area or evade that higher probability of being shot and chooses the animation appropriate for that cover that it is under. Then would evaluate when its best to return fire to attack the player or advance towards the players last position.

The information it would receive would be from the sphere and give everything its own tag being a pillar or rocks or wall etc.

The AI would know the probability of each due to the position it currently is and what has the better coverage by giving each static object its own stats of being shot at if behind the cover and coverage of the NPC or player so it works for both the enemy NPC as a attack strat or defensive strat. It would also make its own probability using those base stats depending where it is and where the player was last seen.

[cosmic rain]

Sounds like a plan. Can't see any obvious roadblocks, but there might be some that you discover during the implementation.

[dense estuary]

I just rewrote that to account for the y axis and also applying gravity manually but that makes me still slide down slopes. Here is my code now. Here is a video: https://streamable.com/q1lffb

[dense estuary]

I fixed the gravity so the player nolonger slides down slopes, however, the player now goes up the slopes slightly due to the gravity now pointing to the slope. Heres the code. https://streamable.com/5oua4k

[solid slate]

i was watching a tutorial and i saw this guy make a float and he put {get; private set; } after the float name what does it mean and how and when do you use it

[lean sail]

the gravity doesnt need to point in the direction of the normal

[lean sail]

it is a property https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[solid slate]

ye but i dont get what the point of it is

just for security?

[dense estuary]

By default variables are private

I believe

[lean sail]

you'll find answers and examples online if you google why. you can accomplish the same with methods but its just nicer sometimes to use a property

[solid slate]

i did google i just dont see the point tho

il try looking more

[lean sail]

theres really a lot of reasons that they are used, a simple example is just the basic one you wrote.

public float SomeValue {get;  private set; }

it is publicly available for things to get (read) but can only be set (write) from within this class

Otherwise you need the java way

float someValue;
public float GetSomeValue() { return someValue; }
void SetSomeValue(float someValue) { this.someValue = someValue; }

[somber nacelle]

properties should also be preferred over public fields so you have finer control over what can access your data and how that data is accessed. you should very very rarely use public fields

[lean sail]

Ah im too tired rewrote my example like 3 times but now its correct lol

[prime cosmos]

has anyone ever seen this error before:
BadImageFormatException: Format of the executable (.exe) or library (.dll) is invalid.
I get it when I try to export my project to iOS and it fails build every time. Tried reimporting all assets that did not work.

[somber nacelle]

#📱┃mobile for issues regarding building for mobile devices

[spring creek]

If you don't declare an accessor, yes. The implied accessor is private.

[dense estuary]

Do I need to disable gravity if the angle returned is greater than 0?

wouldnt that make me hop down the slope

[lean sail]

if you are handling gravity yourself at all, i would just disable it entirely and do whatever you want yourself

you want it to be 0 if on a slope you're allowed to stand on

[dense estuary]

You said to just disable gravity? https://streamable.com/pfvke2

[lean sail]

well now you need to handle the gravity yourself..

[dense estuary]

Thats what I'm doing in the code I thought?

[lean sail]

🤷‍♂️ im still not sure why you are adding gravity in the direction of the floor in that first statement but really id just add debug draw rays for everything when making a movement system

im not even sure what your IsGrounded() logic is doing so i cant be certain that the else statement part is even running

[dense estuary]

The IsGrounded() logic is, shooting a spherecast down, and if it hits anything other than the player, than it returns true.

I think hit.normal is null if the player isnt grounded.

[lean sail]

normal is a vector3, it cannot be null

[dense estuary]

so its Vector3.Zero?

[lean sail]

instead of assuming what the code is doing, add debugs and check

yes though, a vector3 is by default zero

[dense estuary]

Instead of adding gravity in the direction of the floor, I am now applying it when the player is not on the ground, however, this causes the player to float up strangely on slopes. https://streamable.com/ctmpof

if (!IsGrounded())
{
    rb.AddForce(Physics.gravity, ForceMode.Acceleration);
}```

The issue seems to be partly fixed when I decrease the distance of the spherecast, I discovered that from debugging the gravity application. https://streamable.com/8z2b42

[solid slate]

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

how come it doesnt go back to 1st animatin and goes back to idle fast

[indigo verge]

Question, if you edit the "motion" of an Animator's State through code during runtime, does that just affect the one object, or all objects using that animator?

[rigid island]

put breakpoints

[gray mural]

All.

[gray mural]

I would recommend you to always apply the gravity, regardless of your player being on the ground or not.

This way, you wouldn't need to worry about the sphere cast being casted correctly

And in the real world, it's usually so that the gravity is applied to you not just when you jump or fly (do you?), but also when you walk and sit

Therefore, simply always adding the gravity to the bottom, which is, yeah, Physics.gravity = Vector3.up * -9.81f, is a great solution

[lean sail]

That's all fine in theory, but video games do not reflect real life. The gravity being applied every fixed update is what's causing them to go down slopes over time. There is no need to fight the system, the gravity simply doesnt need to be applied if they can stand on such slope

Using real life would only be applicable if you're trying to make the best active ragdoll simulator. Which alone requires extensive skill

[gray mural]

Alright, if the gravity is what causes them to slide down the slope over time, they might consider either applying the gravity when the object isn't ground, which should be checked with a sphere cast with a small radius, or applying the gravity in the direction, perpendicular to the slope, where it might also be great to change the rotation of the player to match the gravity.

[lean sail]

This really reads like AI...
Rotation of the player to match gravity?

[gray mural]

What are you talking about? Rotate the player to match the gravity.

Consider reading the 2nd option fully.

Does this perhaps make it more clear for you?

[lean sail]

I have read it fully, and I am convinced there are either translation errors or some AI text used in some of your responses (not just from today).

[lean sail]

This is the normal of the ground. Not gravity

[gray mural]

I don't remember using translation in my previous response. Perhaps you're reffering to my bad English? Well, I'm currently working on its improvement.

[gray mural]

What is it supposed to mean?

The arrow is supposed to show the gravity's direction, perpendicular to the slope in this case.

[wintry gust]

What bawsi is saying is that you would take the normal from the slope/ground that the player is standing on and use that as it's new up vector.

Which I believe is closer to what you actually want

[gray mural]

The up vector isn't the same as the gravity

[lean sail]

The line coming straight out of the ground is the normal yea. Gravity would just be a line pointing straight down regardless of the slope here.

[gray mural]

The normal gravity is applied to the bottom, shown with the blue arrow.

The green arrow is the force you want to apply to the player in order it to move forward (or, well up? cause it's a slope)

The red arrow is the force I'm talking about. The force which is supposed to be applied perpendicularly to the slope's angle.

(there's even the 90deg angle shown)

[lean sail]

There is no red force. This simply doesnt exist, that red line is just the negative of the "normal", since it's supposed to point outwards

[wintry gust]

The slope up vector is the same as the red arrow, just flipped basically.

Also that is very good art 👍

[gray mural]

Of course it doesn't exist. That's what we're talking about all this time.

It should be implemented for the player not to slide down the slope, as it usually happens with the blue arrow

[gray mural]

And the rotation of the player may also be changed according to this force, as I have previously mentioned here

This is, actually, what is usually done in this kind of games, when the player climbs different surfaces, like slopes, walls and ceilings etc.

[loud wharf]

Normal means the tangent + 90 degrees from a point in a line.

Tangent meanwhile is the direction that a point in a line is going to.

[gray mural]

I see, so the perpendicular vector.

[loud wharf]

You can calculate tangent by:
lim -> Delta = infinite: arctan(y1 - y2 / x1 - x2)
Where Delta is the span between 1 and 2 and gets more accurate as delta goes toward infinity.

[gray mural]

Also, how would you get a tangent from the point in a line, which is a vector, if the angle is supposed to be passed into the tangent function?

[loud wharf]

Normal is a direction. Not really a vector. Mathematically speaking.
Normal is passed as a Vector struct in unity but it has no magnitude (magnitude = 1) and you normally use it as a direction component.

To actually be a vector it must have direction and magnitude.

[gray mural]

Well, I don't think the tangent is required to find the normal of the direction.

You dimply replace the x with the y

[loud wharf]

Hmmm I don't think that's correct.

Yeah.

[gray mural]

Don't mention the image I sent. That was wrong.

[loud wharf]

Real.

if you really want to work with Angles or Rotation structs, i happen to made two structs.
Angle struct and SinCos. I made SinCos after feeling bad that i use about a ton trig functions per frame for one thing.

[loud wharf]

The correct way is this.
cos is the x and sin is the y.

        /// <summary>
        /// θ + 90°
        /// </summary>
        public readonly SinCos Plus90Deg => new SinCos(cos, -sin);

[gray mural]

The x and y axes are replaced.

And so the angle between them is 90

[slim gate]

How do you guys handle tracking of stats/ unlocking achievements on steam? I have been thinking about my implementation for a while but it seems not ideal.

On the one hand I want to store stats per stage in my game, but also stats for the whole playthrough. So I was thinking of something like this:

public class Stats
{
    public List<Stat> StatList = new List<Stat>()
    {
        new Stat("ENEMIES_KILLED"),
        new Stat("DAMAGE_TAKEN"),
        new Stat("DEATHS"),
        new Stat("GOLD_EARNED"),
        new Stat("GOLD_SPENT"),
        new Stat("DEPTHS_SURVIVED"),
        new Stat("REVIVES_DONE"),
        new Stat("REVIVES_RECEIVED"),
        new Stat("ITEMS_CRAFTED"),
        new Stat("ITEMS_REFORGED"),
        new Stat("ITEMS_BOUGHT"),
        new Stat("ITEMS_SOLD"),
    };
}

public struct Stat
{
    public Stat(string name)
    {
        Name = name;
        Value = 0;
    }

    public string Name;
    public int Value;
}

To hold all the data for the stats, and then a handler for everything with something like this:

private static Stats _depthStats = new Stats();
private static Stats _gameStats = new Stats();

public static void DepthFinished()
{
    // TODO: Add current depth stats to gamestats and set new depthstats
}

But it feels wrong to me, I want to unlock achievements straight when the condition is fulfilled and not at the end of each stage/ depth, but also checking for x conditions and manually adding one if statement for each achievement always when a stat is increased feels wrong and inefficient. There must be a better solution?

[gray mural]

It's just the sin = cos and cos = -sin. Could you, please, show how you would actually implement it via code?

[loud wharf]

The one on the first quadrant is (3, 7).

x normally comes first.

[gray mural]

Yeah, that was a typo

[wintry gust]

This is a surprisingly in-depth conversation for a problem that's somewhat basic lol

[loud wharf]

It's cause i love helper functions.

[gray mural]

Would you be able to provide a basic solution for this somewhat basic problem..?

[wintry gust]

I'm enjoying it, ignore me!

[gray mural]

I love em too

[loud wharf]

This also comes with unity custom editor. Albeit ranged from -180 to 180. SinCos can't express entire rotations.

[loud wharf]

I also have angle struct and a property attribute. I might as well paste em ehre.

[gray mural]

I have a Helper script with all the possible static classes like RectHelper, MathHelper, TransformHelper etc.

[gray mural]

Someone really loves angles

[loud wharf]

More like someone hate fucking with both radians and degrees at the same time.

[gray mural]

And #ifs

[loud wharf]

It's mostly so i can copy and paste for Godot and unity.

Then i found out unity can't serialise readonly so i have to add that in too.

[gray mural]

But well, why would you even spend your time writing literally the full Angle struct? 🤔

[wintry gust]

The solution was mentioned already. Take the normal direction of the slope, use it as the up vector as movement cross product. But to be fair there is multiple ways to solve slope issue.

[loud wharf]

Mostly, i want to just build in the helper functions instead of having a DegreesToRad or RadToDegrees. I'd just make more functions that just take the Angle.
And then after that that i use trigonometry a lot for controlling joints and added SinCos and use that instead (when using a singular direction value is not important) and added an implicit cast for Angle to SinCos.

[gray mural]

Sounds damn hard

[loud wharf]

Is it? It's literally just a wrapper for a float.

Cause if that's the case, why people even use Vector2 instead of a (float x, float y)?

[gray mural]

Alright, maybe, but 311 lines is like

[loud wharf]

311?

[gray mural]

missed "lines"

Also, this looks strange

public static Angle Deg360 => one_revolution;
public static Angle Deg270 => three_quarters_revolution;
public static Angle Deg180 => half_revolution;
public static Angle Deg90 => quarter_revolution;
public static Angle Deg45 => eight_revolution;
public static Angle Deg1 => one_degrees;
public static Angle Deg0 => no_rotation;

public static Angle OneRevolution => one_revolution;
public static Angle HalfRevolution => half_revolution;
public static Angle QuarterRevolution => quarter_revolution;
public static Angle EigthRevolution => eight_revolution;

[loud wharf]

I just did that because Monogame Vector2, UnityEngine Vector2, and even Godot Vector2 did that.

I'm not really sure if it makes a difference for a readonly static.
There's a multiple getters for the same value because i felt like it. I just wanted to express the same constant value in different measurements.

[gray mural]

Deg360 = OneRevolution

[loud wharf]

Angle can go above 360. And below -360.

Well angle is a scalar quantity. My source lol.

[vague tundra]

How might one store some data between scene loads?
And how might one store data between game runs?

[vagrant blade]

Using something like JSON

[vague tundra]

Cool - and that would be a suitable option for both saving state "quickly" between scenes, as well as the entire game state?

[vagrant blade]

Both yeah. Saving the state between scenes is saving the entire game state.

[vagrant sparrow]

Does anyone else have trouble with Visual Studio and creating new files in the Unity Project Explorer? Every single time I create a new file, VS will eventually freeze up and require me to kill the process. This happens in all Unity 2022 versions with VS 2022 and newest Visual Studio Editor Package. (NOT VS Code)
My workaround is to declare classes in the same file and then use the VS refactor "Move to new File" instead, but this is driving me nuts

[chilly surge]

Are you using the "Visual Studio Editor" package or the "Visual Studio Code Editor" package?

[vagrant sparrow]

Visual Studio Editor

[chilly surge]

Okay just making sure because your original message says Code.

[vagrant sparrow]

Ah yeah, sorry I just noticed now

Also when attaching the debugger I very often get a 30-60 second Unity Editor freeze before I can continue. Not sure if related. Ive tried reinstalling both

[gray mural]

That's alright

[vagrant sparrow]

Its not alright. I dont want to wait, and it didnt use to be like this

[gray mural]

Well, it's always been this way for me

[vagrant sparrow]

Ive been doing this for 12 years. It wasnt always like this 🙂

[latent latch]

restarting the editor works for me at times

[gray mural]

Times change

[narrow kite]

(problem solved)

I use this code for my scp173-like enemy, which chases after the player when the player doesn't see it

[vagrant sparrow]

try if (Physics.Raycast(cam.transform.position, dirToEnemy, out hit, distToEnemy, 1 << groundLayer))

[knotty sun]

So why not Debug the parameters passed into the RayCast?

[narrow kite]

i will try that

[vagrant sparrow]

Also, ensure that your ground objects are actually on the GroundLayer

[woeful narwhal]

is there a way to check the canvas a gameobject is on?

[knotty sun]

explain

[gray mural]

"Is there any way to check whether the Canvas' GameObject is enabled?"

[gray mural]

Yes, using yourCanvas.gameObject.activeSelf boolean

[woeful narwhal]

like ive got a gameobject on a canvas and i need to find the rect transform of the canvas so i need a referance to either its recttransfrom or its gameobject

[gray mural]

It still doesn't make much sense

[woeful narwhal]

sorry im not very good at explaining

[gray mural]

You want to access Canvas' RectTransform?

yourCanvas.GetComponent<RectTransform>();

[knotty sun]

ok, generally a Canvas is a Root object so you can use gameObject.transform.root to refer to it

[vagrant sparrow]

youve got a GameObject UNDER a canvas right? as a child of the canvas? If thats the case you can either use GetComponentInParent<Canvas> or simply use an inspector reference

[woeful narwhal]

its like a grandchild of the canvas

does get component in parent still work with multiple children

[vagrant sparrow]

Gets a reference to a component of type T on the same GameObject as the component specified, or any parent of the GameObject.

[woeful narwhal]

ok ill give it a try sorry for the hassle

[buoyant mural]

Is the Canvas the root object?

[knotty sun]

not necessary, if the Canvas is on a Root game object transform.root will give you the RectTransform you want

[vagrant sparrow]

Also that, canvases are usually the root

[woeful narwhal]

the canvas is on a organisational empty game object called canvases

[woeful narwhal]

this seemed to work tho

[vagrant sparrow]

Canvas is a built-in Unity component, so if you decided to call an empty gameobject "Canvas" (without having an actual Canvas on it), you should lead with that when asking for help 🙂

[woeful narwhal]

no yeah im still trying to find the canvas component but ive got all my canvases on another gameobject called canvases for the sake of organisation

[knotty sun]

then I would suggest you put a singleton on that root gameobject which holds references to the children you need

[woeful narwhal]

I was gonna do that but i wanted to use the amount of references on my singltons sparringly because having to many would make unnessary strings of referances throughout my code

[latent latch]

GameManager that has a reference to GameUI

fixed your problem

[knotty sun]

better that than wasteful GetComponents

[woeful narwhal]

yeah good point

what does get components do that are so bad anyways

[knotty sun]

in your case it has to scan through the hierarchy which, by the sound of it, is unnecessary complicated

when you add gameobjects purely 'for organizational' purposes you are doing yourself no favours

[woeful narwhal]

is there a way to make folders in the hieracy then?

because i just struggle havign heaps of gameobjects lying around when im trying to find specific ones

[knotty sun]

no, but why would you need them?

[woeful narwhal]

because just say when my project gets more complicated and i have like 10 canvases then it would be helpful to have them under one folder or gameobject to make them easier to find

not saying id ever get 10 canvases

but i use it more for different cameras

[knotty sun]

there is this amazing thing that the brain can do, it's called 'knowing what you have done and remembering it'

[woeful narwhal]

ive got a pretty bad memory

[knotty sun]

well you will have if you never exercise it

[near vector]

how do I do this

[knotty sun]

you put the variable initialization into the Awake method

[near vector]

ohh

thx so much

[knotty sun]

Also, I would advise changing staff into Staff

https://hastebin.skyra.pw/cadopuqunu.cs

[dense estuary]

applying the gravity in the direction perpendicular to the slope causes the player to move slightly up the slope when jumping, due to the gravity pointing in that direction. Are you saying to apply both gravity and gravity again but in the direction perpendicular to the slope?

like this

This makes the player not slide down the slope, but now they struggle going up.

I'm going to try something rq.

[pastel marsh]

i added minimax
though i do want to stop it from not letting the player to win to also letting itself win
like
in the first game it wins, but in the second game it blocks the players win even though it had crealy a chance of winning

my code for minimax is something like this

 private int MiniMax(int depth, bool isMaximizing)
    {
        if(CheckWinner() != "N")
        {
            if (CheckWinner() == "D")

            int localBestScore = int.MinValue;
            for(int i = 0;i < 9; i++)

                    values[i] = 0;
                    localBestScore = Mathf.Min(localScore, localBestScore);
                }
            }
            return localBestScore;
        }
    }

[dense estuary]

I got it working. cs var gravity = Physics.gravity; var newGrav = RotateVel(gravity); if (SlopeCheck()) { gravity = gravity / 2; newGrav = newGrav / 2; rb.AddForce(newGrav, ForceMode.Acceleration); Debug.DrawRay(origin, newGrav, Color.blue); } rb.AddForce(gravity, ForceMode.Acceleration); Debug.DrawRay(origin, gravity, Color.blue);

Here is how it looks: https://streamable.com/jzlvt2

[gray mural]

No, I'm saying to apply just the gravity perpendicular to the slope, drawn red in the image below.
Yes, it was actually meant to slightly move the player up the slope when jumping, and I also meant you to rotate the player, when the surface's angle changes.

If you don't want this kind of logic with rotation, consider returning to your previous solution, using either aSphereCast or Ray

Just be careful with using radiuses / distances

[gray mural]

Looks great. You may want to just apply the gravity to the bottom when the SlopeCheck() fails

Also, probably consider not dividing the gravity values by 2

[dense estuary]

I was only dividing them by 2 on the slope because if you apply 2 gravity's the force is stronger. But now that you said to only apply gravity to the bottom when the SlopeCheck() fails, I don't have to divide them since only one gravity is being applied at once.

[gray mural]

Right. Also, I forgot to mention it. How do you check if the player is grounded?

Consider using the OnCollisionEnter and OnCollisionExit methods to change the boolean isGrounded to true and false respectively. That's, honestly, the most reliable option.

[dense estuary]

I shoot a spherecast from the center of the player downwards. The sphere has a radius of 0.49f.

[frail bone]

Silly question, why's the reason a modifier is changing the prefab and not the actual instance

[gray mural]

Well, yeah, consider using the method I've shared in the previous response

[gray mural]

What kind of a modifier?

If you have a reference to a prefab, changing it will, obviously, change the prefab, not a random GameObject somewhere in the scene

[frail bone]

Just a float for the health

[spring creek]

Because you are using the prefab reference instead of the reference returned by instantiate

[gray mural]

Well, do you mean, you change a float in the Inspector?

[frail bone]

Yes, well, it's supposed to change the UI but the UI is attached to the instance not the prefab so right now it doesn't change anything

[dense estuary]

Why should I use that instead of a spherecast?

[gray mural]

Because it's much more reliable

[spring creek]

Not really sure what you are saying here.

[gray mural]

Me either.

[dense estuary]

How so?

[gray mural]

Could you, please, explain the issue better?

[gray mural]

Well, if you want your SphereCast to work properly, you will have to find a proper radius and its location.

By using the OnCollision methods make your collision be checked by Unity

This will almost always be much more accurate

Just make sure you check the collision with desired ground GameObjects, which should usually have a Ground tag

[frail bone]

I just need to know how to call the instance rather than the prefab

[spring creek]

Instantiate returns the instance

Cache that reference being returned

var instance = Instantiate(prefab)

[copper atlas]

Hi im trying to resize the children of paisagemRight through script
I tried 2 ways that appear in the 3 and 4 pic and it happens the result in pic 1 does anyone know why those wireframes appear with the resizing and the actual object not?

[gray mural]

As Aethenosity has mentioned, you have to spawn the prefab using the Instantiate method and get its returned value

T instance = Instantiate<T>(prefab, prefab.transform.position, prefab.transform.rotation, prefabParent);

[gray mural]

I'm sorry, I don't seem to understand what you're saying. Could you, please, express yourself a bit better?

[copper atlas]

sure

[gray mural]

[gray mural]

Please, consider using one of the sites I've previously sent for the large code blocks.

Is there a way in Unity to develop like a class diagram kinda thing that will generate a graph of how all the different components in your project connect? Like a model-view-controller diagram for Java

[knotty sun]

Absolutely. Unity has an experimental Graphview API
https://docs.unity3d.com/ScriptReference/Experimental.GraphView.GraphView.html
which you can use to develop any kind of graph view you wish

[spring creek]

Then do gameObject in a script on that gameobject.
That will be the instance, not a prefab

[frail bone]

I did that though

[spring creek]

Then you were not affecting the prefab

Prefabs do not exist in the scene. Maybe that is the confusion?

[frail bone]

then why does it modify the prefab and not the game object

it's a ontriggerenter2d

the is an issue with that specific line but im not sure how i am supposed to explicitly call the game object

[spring creek]

It doesn't, it's just saying you never set a reference to the playerHealth

At least that is what it looks like

You cropped off the line numbers, which is super unhelpful

[frail bone]

I did call the script

[knotty sun]

That is irrelvant. Your line 16 is not working as you think

[spring creek]

Is player health on the same object as enmigo?

That would be suprising

And also, we have now proven this issue has absolutely nothing to do with prefab vs instance. If you had just shared your code to start with, we would have told you that from the beginning
The issue is that you need to look at the docs for GetComponent

[frail bone]

No

Player health is on the player while enemigo is on the enemy

[spring creek]

GetComponent returns a component attached to the SAME object, or null if it doesn't exist

[frail bone]

Ohh

Lemme check the documents

[frail bone]

I can just erase that line but the error still stays

[ancient canopy]

Hey guys, i was wondering how you are loading game settings on game startup.
I found this mothod extention which executes the method before splash screen, or other times if wanted.

    private static void LoadAudioSettings()
    {
        AudioMixer masterMixer = Resources.Load<AudioMixer>("Audio/Master");
        if (masterMixer == null) return;
        
       masterMixer.SetFloat("Master", -40f);
    }```

The method does execute, AudioMixer is present.
But the volume is still 0 for the mixer. 
I did execute this method later on by button press and it works like a charm.
Why doen't it set the volume on startup even tho the method gets executed?
Do you use another way to set the player settings on startup?

[spring creek]

Well yes, you still have to set the reference

[worn crystal]

is there any performance advantage enabling isTrigger on a non moving object?

or is the performance only based on how many other colliders/triggers it needs to compare against in scene?

[somber nacelle]

isTrigger has nothing to do with performance, it makes a collider a trigger volume instead of a solid collider

[worn crystal]

yeah which means that things like rigidbodies cant interact with it

so does this save any performance?

[somber nacelle]

incorrect

[spring creek]

Yes they can

[worn crystal]

wait really?

[spring creek]

OnTrigger requires a rigidbody

That is an interaction

[worn crystal]

ohhh i meant directly collide

but i get what you mean yeah

i guess the comparison is still being made so its not factoring it out in any case

[spring creek]

I mean. I would say performance is completely irrelevant

If you want them to collide, don't use ontrigger

If you don't and still want a physics message, then make it istrigger

[worn crystal]

ill explain my case from the root, i pretty much just have a collider on many objects so that once the player char walks behind it from the camera's POV itll attempt to fade it and make it transparent

[spring creek]

You can disable layer interactions in the matrix too

[worn crystal]

i dont want to have like 200 objects with colliders in scene if possible but was wondering if isTrigger would somehow help lol

[gray mural]

Yes, it will slightly increase the performance over the case when this object has isTrigger disabled, assuming it collides with the other objects, because Unity's physics will need to calculate those collisions. Enabling the isTrigger boolean makes those collisions be ignored.

[worn crystal]

they are on a different physics layer too though so them colliding with something was never an issue

[somber nacelle]

just to confirm, this is for a feature of your game and not some weird attempt at culling non-visible objects, right?

[spring creek]

If the interaction between layers is disabled, it will not make any difference in that specific case

[dusk apex]

I think the collision/trigger detection is the limiting factor here and not the displacement (math).

[worn crystal]

feature, so that once the player goes behind some obstacle the view isnt completely obstructed so i raycast against the collider and grab a script to fade in/out the object

and yeah dalphat pretty much, im not concerned about it colliding with anything at all, just purely in terms of which one is more performant (if any), but i guess because theres nothing in scene that will ever collide with these objects the impact would most likely be 0

[dusk apex]

If you're wanting to have multiple objects with colliders in the scene, the more common optimization would be to differentiate between static and dynamic bodies. Other than that, there's going to be some expense relative to the number of physics objects in the scene.

[latent latch]

the best answer you get is profiling it yourself

[worn crystal]

yeah i think it comes down to just profiling tbh, not wrong about that

[latent latch]

Just my experience with filtering out colliders, there is still some cost even if they aren't on the same layer

abit minimal at that

[worn crystal]

Got it, I'll have to profile it in that case and see the impact

Appreciate all the help!

https://hatebin.com/mrmaiowhni

[knotty sun]

it might help if you explain what 'some problems' actually means

[somber tapir]

[knotty sun]

[latent latch]

AnimalData<T> : ScriptableObject where T : Animal
List<IAnimalData>

I actually don't know the real issue, but usually if you want to contain the root of the constraint you usually also want to make an interface

[somber tapir]

I need to have a serializable List<AnimalData> somewhere to spawn any Animal.
Using an interface could work, just have to work around that Unity can't serialize interfaces by default.

[latent latch]

right, that's the unfortunate part

good code dies with unity

[latent latch]

Actually im kinda confused why it's not Animal that takes an SO of Animal data

[mossy snow]

your design on this is weird. If AnimalData exists solely to provide default values that Animal copies every time, put those fields into Animal and delete Setup and AnimalData

Animal then becomes an abstract generic class with an abstract CreateCopy method, and each subclass implements it

actually why do you have a copy there at all?

[toxic prawn]

            if (hit.collider.TryGetComponent(out PhysicsSurfaceData physicsSurfaceData))

                print("step taken");

            }

how do I add bobbing to this (Im using charactercontroller)?

[slim gate]

So a far as I am aware calling:

Singleton.Instance.PlayerScript;

Is not causing any relevant overhead.

What about:

Singleton.Instance.PlayerScript.gameObject;

Is the .gameObject in the end something where I should probably cache it instead referencing it through the singleton every frame if i need this in update? Or is it insignificant and I can do it like this in update?

[knotty sun]

no, it's just a reference so little to no overhead

[slim gate]

perfect

Thanks alot!

[latent latch]

this is like a micro-micro optimization

[slim gate]

yeah, if i can i would like to do it like this to not have to set things up anywhere I need it

and cache it in each script where I do

Makes it nicer to have it one place

[sly comet]

this is how I have my player object set up. You can only swap skins in the menus. So once the game starts my script only activates one of these models and the rest are inactive until you visit the menu again and can cycle through them (array for both model and matching animator). Is this a hit to performance? Should I do more than deactivate the unused ones?

[slim gate]

why not just switch the spriteRenderer/ model? Not sure if that is a solution in your case

I have one Gameobject for the visuals of my character and depending on race etc i just switch a sprite

[sly comet]

idk someone in here showed me this is how they do it.

it seems to work great but I have a beefy pc

[lean sail]

Since they're all disabled you really wont have a performance issue but itll be way worse loading many of these compared to if you just had one

[slim gate]

Not sure if what I said would be any significant improvement for performance, I assume it would be better there in some way but I would do it just for having your player more compact and readable

[lean sail]

This also looks like hell to edit if needed.

[slim gate]

yeah exactly

Thats what I mean

[solar wigeon]

https://gdl.space/qenaguqiso.cpp
hello i really dont understand the problem with my code basicly if i touch a trigger i should start a timer and the text get enabled for a few sec and then just go to setactiv(false) what can be the problem ?

[lean sail]

You are using start here, which runs once. You need Update

Also subtracting by the timescale doesnt make a whole lot of sense, I assume you want deltaTime

[solar wigeon]

ok i will try that

[main coral]

    {
        int playerCount = NetworkManager.Singleton.ConnectedClientsIds.Count;
        int temp;

        do
        {
            temp = UnityEngine.Random.Range(0, playerCount - 1);
        }
        while (m_SpawnPointIndexList.Contains(temp));

        m_SpawnPointIndexList.Add(temp);
        return temp;
    }```

Hey i want for each player a random number bot every number only once. But my game is crashing what is false on this while loop ?

[solar wigeon]

https://gdl.space/emilerayir.cpp
it works but now text dosent go away

nether does timer becomes false

[toxic prawn]

how do I make everything but one script to just pause without breaking them?

[leaden ice]

Vague question. Time scale generally

[solid slate]

whats that

[toxic prawn]

I mean pausing everything but sounds to make it look like it crashed

[dusk apex]

Maybe consider not relying on luck to not select an already found item and simply maintain a copy of the collection - relative to what's available left. Remove items as you use them etc.

[main coral]

I want a Spawn Vehicle system for my cars for the first round that everyone get a random spawn point. When 8 players are connected I want that everyone get a random number between 0-7 but every number only given once

im thinking since days and i dont have a solution. i tried many things ..

[solid slate]

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

how come it doesnt go back to 1st animatin and goes back to idle fast

[main coral]

Trhis should work?

    {
        int temp = UnityEngine.Random.Range(0, m_SpawnPointIndexList.Count);
        m_SpawnPointIndexList.Remove(temp);
        return temp;
    }

    private void CreateStartPositionList()
    {
        int playerCount = NetworkManager.Singleton.ConnectedClientsIds.Count;

        for (int i = 0; i < playerCount; i++)
        {
            m_SpawnPointIndexList.Add(i);
        }
    }```

[dusk apex]

```private List<int> ids = new List<int>(8); ``````cs
for(int i = 0; i < count; ++i)
ids.Add(i);

int index = Random.Range(0, ids.Count);
int temp = ids[index];
ids.RemoveAt(index);
return temp;```

thanks alot is working!!"

[lean sail]

Look at the code logically. You are subtracting from a value starting at 0. How will that 2nd if statement ever be true if the timer was true?

[devout harness]

Is it possible to create realtime HDRP reflection probes at runtime? I'm noticing they don't budge from baked (the default) when changed from a script- is there some hidden fields I need to configure first?

[wicked badge]

anyone know how to fix this?

cause ive been trying to fix it for 30 mins and nothing is workin

[hasty haven]

Is there a way I can get a reference to a scene after loading it additively async?
I'm trying to manage multiple instances of the same scene

[rigid island]

there is scenechanged event, not sure if it works additively though

it gives you old scene / new scene

[somber nacelle]

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneLoaded.html

[rigid island]

nice

[hasty haven]

Would this work in the case where many load requests can happen in no particular order?
I want to trigger the load and have the reference in the same coroutine

[solid slate]

https://hastebin.com/share/odufabuvol.csharp why when the first animation plays it is delayed and sometimes goes to idle'

[broken nest]

There are two ways that I know of:

1. if you have a gameObject that you know is part of the scene you're looking for, you can call gameObject.scene
2. if you're adding scenes through code and need cross-scene access, you can have the script that spawns the scenes keep references to them.

[rigid island]

you probably need to sub this on a DDOL

[hasty haven]

Hmm alright this might take some experimentation

I suppose it doesnt really matter what the order is as long as its the correct scene type and a unique instance,
I'll try working with the event since it gets called once after each scene loads

[solid slate]

https://hastebin.com/share/odufabuvol.csharp why when the first animation plays it is delayed and sometimes goes to idle'

[dawn nebula]

So when you select the Rect tool and then a gameobject, you can see these "anchor points" and rescale the object. Is there any way to interact with these anchor points in code?

Or helper functions that simulate behaviour?

Because really all they're doing is modifying the scale and repositioning the object.

[crystal bramble]

i have a question

[leaden ice]

most likely using the Renderer's bounds

but the scaling would just be happening via the Transform

[mild osprey]

I have a text system that that types out a message letter by letter and plays a sound every X letters typed. Issue I'm having is that it seems to be framerate dependent and I'm not exactly sure why. I've tried formatting the code in a couple different ways but it still ends up with the same result. Here's the coroutine that handles the logic:
https://hastebin.com/share/niyezoquce.csharp
and an example of the issue is shown below.

[indigo verge]

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

Can someone look over this and tell me what they think? I'm working on making an implementation for dynamically changing animation clips on a per-object basis, so I can play animation clips directly from file instead of having to shove them all in a mekanism tree, and dynamically modify animations as needed.

Am I doing this right? This should be creating an instanced override controller for whatever object calls it, which can then be modified without altering the animations of any other object in scene, but I'm new to working with these systems.

[sly comet]

Would anybody that understands how to build a ghost time trials script and how to save/load that data be able to tutor me in voice chat for a bit? I think it would take us a very short amount of time and I have venmo for your troubles. I would appreciate the help. I can figure out the animations and all of that. I already have the scripts functioning. I just need to know how to get them to save/load properly as well as verify it all works. I already have a saveGameManager that works for levelData I just want to get it working for this ghost data now

[dense estuary]

I am experiencing an issue where the radar gun in my game is moving very jaggedly. Here is my code. https://streamable.com/aj9evr

[solid slate]

https://hastebin.com/share/odufabuvol.csharp why when the first animation plays it is delayed and sometimes goes to idle'

[rigid island]

your lerp is wrong

rewrite it , or Use MoveTowards

[dense estuary]

But I thought this was correct?

[rigid island]

yeah but you're changing the startPos the lerp each frame

https://unity.huh.how/lerp/coroutines

as you're setting the pos you're changing the startpos of lerp it doesn't know how to act

[dense estuary]

ooh, the same thing I'm doing for changing the color of my radar icons. ```cs

iconImage.color = startColor;
yield return new WaitForSeconds(0.5f);
float time = 0;
float duration = 2f;

while (time < duration)
{
iconImage.color = Color.Lerp(startColor, endColor, time / duration);
time += Time.deltaTime;
yield return null;
}```

This is in a coroutine

[rigid island]

note how its start to end, rather than current to end
and the startCol only gets recorded in 1 frame then on the smoothing / over course of frames it stays same for start

[sly comet]

I feel like I'm so close to having this solved. If anybody could tutor me for 10-20 mins while I share my screen I would send some tutor wages your way

[devout nimbus]

Anyone have good resources on pathfinding in large open worlds?

[dawn nebula]

Ya was just wondering if there was an inbuilt way to do it.

[rigid island]

either do realtime mesh baking or you'd have to create a more localized custom grid/avoidance

[dawn nebula]

Otherwise I guess I just do some math and move the position.

[solid slate]

https://hastebin.com/share/odufabuvol.csharp why when the first animation plays it is delayed and sometimes goes to idle'

[devout nimbus]

Yea I figured, Ill have to likely to split the mesh into multiple sections then. Just wondering if there were any resources going into this more in depth that you might know of

[rigid island]

no reason to split anything, just bake an area around the character each time it moves a certain amount bake again

[devout nimbus]

Im using the terrain tool, are you able to split the mesh to bake only certain parts of it? I assumed you baked the entire mesh at once @rigid island

[dense estuary]

I've just applied this to my code and the positioning is working much better. https://streamable.com/ydv895

[rigid island]

there are tools like area baking / volume baking

nothing to do with terrain

https://youtu.be/RuoK7w1OIT0

[devout nimbus]

Thats a big help thank you. I didn't know you could split it up.

I kept searching online for ways people set up pathfinding for open worlds so I was just hitting deadends when I shouldve looked into navmeshs specifically and I wouldve found answers much easier

[rigid island]

yeah there are other ways to do this, but they require alot more work and code

also you probably wouldn't want to bake realtime for NPCs that are very far away

[vague tundra]

If I have three scenes, MainMenu, Area1 and Area2, and I've added them to the build settings in that order,
When I am editing Area1 and press Play, should I still be able to load other scenes?
Or now that I've added the scenes to the build settings, I must start from the first scene?

[cosmic rain]

The build settings only decide what scenes to include in the build, their indices, and what scene unity would load on launch. Everything else is up to you.

[cloud python]

does anyone know why i'm generating 2 objects instead of just one?
im trying to link the prefab as a child but it keeps making a parentless clone, and then an empty child-instance copy that doesnt actually do anything

they both seem to have the same data except the child instance just doesnt exist

[severe maple]

do you mean the blue thing is rotating on the wrong axis?

[keen swift]

yeah... I'm not good putting things into words

[severe maple]

you want the blue thing to basically rotate on the 2d axis around the middle sphere

instead of rotating on the 3d axis

from what i can understand?

[keen swift]

Yea basically

it's for a cool stamina meter

[rigid island]

which part controls the blue part then

[keen swift]

wdym by that? I assigne the bar to Handle Rec like a normal slider, there's no script to the slider.

[severe maple]

the issue is the blue bars transform

[vague tundra]

How can I open 2 scenes at once, such that each scene has its own Scene and Hierarchy windows/tabs?

[somber nacelle]

pretty sure the answer to that is "you don't"
also not a code question

[vague tundra]

If you could, please don't respond to my questions

[somber nacelle]

why bother asking a question if you don't want a response to it?

[spring creek]

They gave you the correct response. 1) not a code question. 2) you don't

No one else has a better response than that

Two scenes loaded at once share a hierarchy

I dunno about the scene window, I guess some custom editor code might be able to do it. But I've never seen it

[vague tundra]

Just you specifically, please

[somber nacelle]

lmao what the fuck. just block me if you don't want to see responses from me?

[spring creek]

No need to be rude to people. I dunno what your problem is, but, again, they gave you the right answer, and did it politely

[vague tundra]

I've had you blocked for a long time. But once someone has thrown an answer at a question, many would assume it has been answered, and don't bother giving their own. Now of course if your answer was incorrect, someone else might still respond... but regardless. If you could, please refrain from responding to my questions

[somber nacelle]

yeah not my problem. good luck with whatever the hell it is you're doing though 🤷‍♂️

Well, I will also never be answering your questions either.

If some specific logic that's not in a loop is done twice, you're probably starting the coroutine twice. Adding some basic debug logs should prove to you if this is the case

[sick flint]

https://gdl.space/vifetuyoha.cs

I know the coroutine is being called twice. I have used some debug logs but I just cant figure it out. This handle update function is called from a statemachine update

        if(clampedY == 1)
        {
            direction = FacingDirection.Up;
        }
        else if(clampedY == -1)
        {
            direction = FacingDirection.Down;
        }
        else if(clampedX == 1)
        {

        }
        else if(clampedX == -1)
        {
            direction = FacingDirection.Left;
        }
        
        if(prevDirection != direction)
        {
            yield break;
        }``` It is only being called twice when I have this in my code.

[lean sail]

Probably some faulty logic with setting that character.isMoving because that's what would be stopping that coroutine from being called multiple times

[sick flint]

Okay I can look into that. Thank you.

[somber nacelle]

if prevDirection is different than the direction you exit the coroutine. and you do not set isMoving to true until after this code has run. so if you are moving in a different direction than previously you don't consider yourself moving and don't perform the move

[sick flint]

Yes that is my goal. I want to emulate movement such as pokemon soul silver where you're only allowed to move in the direction you are facing but if you decide to turn a different way the character just turns.

[hidden oxide]

Hi! I’m really new to unity/fungus and I’m having a coding issue- could I get some help on it? 🥲

[spring creek]

1. what is fungus in relation to unity?
2. https://dontasktoask.com/

[somber nacelle]

right so on one frame the coroutine is started, it performs everything up to the yield break on that frame, then the next frame the coroutine is started again because the character is still not considered moving but it is incredibly unlikely that you've let go of the input by then

[rigid island]

also dont crosspost

[lean sail]

tbh using coroutines here is likely gonna be more complicated than just using update

[hidden oxide]

Sorry I just joined the server I didn’t know #2 and no one was answering me in the other channel

[spring creek]

Well you didn't actually ask anything
And it had only been a few minutes

[sick flint]

Would you reccomend me turn this into a regular function rather than a coroutine?

[hidden oxide]

I got the error [00:21:19] Assets/Fungus/Scripts/Editor/ViewEditor.cs(140,99): error CS1501: No overload for method ‘FreeMoveHandle’ takes 4 arguments

I’m gonna copy and paste my script in here just gimme a sec

[spring creek]

You still haven't said what fungus is.
But your parameters are wrong

You passed 4 things, and apparantly it doesn't take 4 things

[hidden oxide]

Ok lemme send u the script and u can tell me what to edit

[spring creek]

How could I know.
For the third time, you haven't said what fungus is

[hidden oxide]

Fungus is the unity add on for narrative games

[lean sail]

its up to you, the only part that makes sense being in the coroutine is the while loop part. As boxfriend pointed out, isMoving isn't set until that section. Nothing is stopping the coroutine from being started if it yield breaks out due to an earlier section

[spring creek]

Looks to be third-party. It would likely be best to ask them

[hidden oxide]

Ok

[sick flint]

I will try this and see if it works how I intend. I appreciate the help.

[spring creek]

Unless this is the method you mean?
https://docs.unity3d.com/ScriptReference/Handles.FreeMoveHandle.html

[hidden oxide]

I don’t think so, I’m just gonna ask another server.

[spring creek]

Ok, sorry I can't help.
Good luck

Remember to not ask to ask. Just go for it

[hidden oxide]

I joined the server 5 minutes ago, I wasn’t going to understand the rules right away.

[spring creek]

Oh, this is not a server rule. Just a general life rule

That is why the website I linked to has nothing to do with unity or this server

It is how you should approach all internet communications in forums/servers

Basically, get to the point. No one knows if they would be able to help you before you actually ask the question.

[subtle basin]

I use the Enemy class and WireEnemy inherited from it to control the movement of enemies. During the game, wire enemies can change to an ordinary one, so how can I change type of them to the Enemy type so that all the fields remain the same and the links are relevant?

[leaden ice]

WireEnemy already is an Enemy

[subtle basin]

It overwrites Move method

[leaden ice]

This doesn't really sound like a use case for inheritance

[subtle basin]

what do you suggest?

[leaden ice]

A state machine?

If the only thing different is how hey move... A bool?

if statement?

Composition enemy movement is its own component and you can swap it out with what ever you like

Im using it as a Class but i need to switch to a string once its done

right now its a Interactable currentInteractable;

but i need to convert to a string later on

[quartz folio]

what does that even mean, what is an Interactable and what would it look like as a string

[molten crypt]

cause if i switch it too public string currentInteractable
i get a bigger error

[molten crypt]

a Interactable object in the game

[fervent furnace]

define a sting path property on your Interactable class/struct/whatever

or just clone it if possible

[lean sail]

you can just directly reference the prefab from inspector, instead of using resources here

this will use resources.load every single time you want to instantiate an interactable

why this part of my script works with one client, but not several? If a client sends the ID 123, the game 123 is created and if this same client sends back the ID 123 the server tells it that the game already exists, on the other hand if another client sends 123 after the first client has sent these 2 messages, the server creates a game instead of saying that it already exists, and in all cases the server returns the correct gameID.

How can i do that

[knotty sun]

Your Dictionary needs to be static so it is shared by all players.
Instead of just checking if the Game exists you need to check if it exists and is not owned by this player

In fact your Dictionary should probably be a ConcurrentDictionary anyway

[rough tartan]

Thanks for your help, I didn't understand everything, but I'll look into it!

[toxic prawn]

how do I pause everything except some scripts and sounds to make it look like game crashed?

[molten crypt]

    public void AddToInventory(Interactable currentInteractable)
    {
        whatSlotToEquip = FindNextEmptySlot();
        itemToAdd = Instantiate(Resources.Load<GameObject>(currentInteractable), whatSlotToEquip.transform.position, whatSlotToEquip.transform.rotation);
        itemToAdd.transform.SetParent(whatSlotToEquip.transform);
        itemList.Add(currentInteractable);
    }

Argument 1: cannot convert from 'Interactable' to 'string'

I dont get how to fix this i looked at the error forms etc

    public Interactable currentInteractable;
    void Update()
    {
        CheckInteraction();
        if (Input.GetKeyDown(KeyCode.F) && currentInteractable != null)
        {
            if(!OpenInventory.Instance.CheckIfFull())
            {
            OpenInventory.Instance.AddToInventory(currentInteractable);
            currentInteractable.Interact();
            }
            else
            {
                Debug.Log("inv is fulll");
            }
        }
    }

the Interactable script

[knotty sun]

which string variable does a GameObject have that might be useful in a Load ?

[molten crypt]

wym?

the prefab of the object i want to pickup?

[knotty sun]

exactly what I said. Go and have a look at the GameObject documentation

[fervent furnace]

.load requires a string path, and you pass a instance of your class to it

[lean sail]

you'll have to be more specific at "some scripts". Setting the time scale to 0 might suffice here

[molten crypt]

Are you able to send the right one

[knotty sun]

tbh If you cannot even search the documentation yourself you don't deserve to be helped
https://docs.unity3d.com/ScriptReference/GameObject.html

[molten crypt]

I had the right one. Just wanted to make sure

[knotty sun]

Actually, my bad. this is the one you want
https://docs.unity3d.com/ScriptReference/Component.html

or even this one
https://docs.unity3d.com/ScriptReference/Object.html

[molten crypt]

https://docs.unity3d.com/ScriptReference/Resources.Load.html
this ones too huh

[knotty sun]

not yet, no

[molten crypt]

Why not? if the GameObject is not useful in a load do i even need load at all

[knotty sun]

for Resources.Load you need a string, as you know, what I am trying to teach you is how to get that string

[molten crypt]

So i need to get the GameObject as a string

[knotty sun]

you need to get your object (currentInteractable) as a string and the Object documentation tells you exactly how

[molten crypt]

.ToString()

[quartz folio]

I don't know why you're not just using basic references https://unity.huh.how/references/references-to-prefabs

[knotty sun]

exactly. and ToString() return name so .name also works

[wide mist]

so when will unity finaly do smth that unreal does make our lifes easier ?

liek motion matching .. for example ? to get rid of that ridicolous state machines ? 😄

unity devs should take a look at latest news from unreal 5.4 thats jsut fck insane ..

[quartz folio]

They had a motion matching solution before Unreal, it was just sidelined while they developed DOTS.

[wide mist]

oh did they

is there a video i can see about it ?

[quartz folio]

https://docs.unity3d.com/Packages/com.unity.kinematica@0.5/manual/index.html

[wide mist]

well any ideas if they will resume it ?

after dots ?

[quartz folio]

🤷

[wide mist]

i hope it wont take 10 years

well probably wont

than

[quartz folio]

I presume they'll resume it when they remake the animation system

[wide mist]

well they should

animation system is pretty mutch outdated

automatic rig creation also a sweet thing wiht premade limbs n shit

[quartz folio]

Sadly we'll have to wait for Unity 7 before anything happens, but I imagine it'll be a large refresh with the .NET upgrade. A chance to change the engine properly

[wide mist]

well thats about in 2026 minimum

i recon

[west lotus]

Kinematica is pretty much dead, the original devs are no longer at unity and unity has no interest in maintaining it or further developing it

[quartz folio]

I realise this whole convo is irrelevant to this channel

[west lotus]

It is 😃

[molten crypt]

So i did

Instantiate(Resources.Load(GameObject.ToString(currentInteractable))

And then i get
No overload for method 'ToString' takes 1 argumentsCS1501
I didnt see it on the Docs so i tried to search and i saw the '?' for null
but when i tried

Instantiate(Resources.Load(GameObject?.ToString(currentInteractable) ??)

It still didnt work
So idk if i didnt it right or what

[quartz folio]

Everything you're writing is complete nonsense

[molten crypt]

probably is ngl, im new

[quartz folio]
