[worthy fable]

I'm trying to make a save system for the game. I want to read data from more than one script and throw this data into a json file.
Tried something like this :

data = new PlayerData(_playerExperience.currentLevel, _playerExperience.currentExperience,
    _enemyValueSet.enemyToSpawn, _playerAttack.playerDamage);```
But I can't reach any of the data.

[dusk apex]

What do you mean by you cannot reach any of the data?

[worthy fable]

_playerExperience = new PlayerExperience();
_enemyValueSet = new EnemyValueSet();
_playerAttack = new PlayerAttack();```
This code was generated by copilot and it's not possible to assign this way since MonoBehaviors can only be created using AddComponent()

And I can't find another way to achieve this

[lean sail]

Sounds weird that your player data specifically is a monobehaviour. Also dont ask questions with AI code

Just make it a regular c# class

[worthy fable]

PlayerData isn't a MonoBehaviour, Other scripts are.(PlayerExperience,EnemyValueSet,PlayerAttack)

[lean sail]

If you need to save specific values on the monobehaviour, still just use that script to return its data in a regular class. That class can contain only relevant data

[dusk apex]

To achieve what? Creating new components?

[worthy fable]

Yes

[dusk apex]

You'd just add new components.

[worthy fable]

Creating new components using current values set while playing.

[lean sail]

You've already said what to do here, what part is confusing

[worthy fable]

This code doesn't work

Because of the way I referenced each script

[lean sail]

Yes but you've in the same message written the solution..

[worthy fable]

I think its the problem not the solution

[lean sail]

If you're trying to reference an existing script, then either use GetComponent or drag it from inspector. If you need to add a new script, use AddComponent

[lean sail]

Was that text also AI generated or something in the message we're referring to?? I feel you havent actually read the message properly

"Since monobehaviours can only be created using AddComponent()"

[worthy fable]

Wait so _playerExperience = GameObject.Find("Player").GetComponent<PlayerExperience>();
would work just fine?

[dusk apex]

Oh god, this looks ai generated.

[lean sail]

Yea..

[worthy fable]

Wdym its me writing it

[lean sail]

So many things wrong with this but im stepping away because this deserves to be in code beginner, and you've used AI code, pasted a (error or AI) message which you seemingly didnt read.
Try to use this to learn how to reference an existing component
https://unity.huh.how/references

[dusk apex]

You wouldn't need to necessarily Find anything if you're passing references. Nor would you need Get Component if the references are passed as the correct initial types.

[worthy fable]

Error message was written by me and I've referenced ton of components already. I'm just not used to working with scripts that doesn't inherit from MonoBehaviour. Thank you.

[lean sail]

Down the line, one script is eventually gonna have to inherit from a monobehaviour. Pass the reference directly into there through inspector

[dusk apex]

var instance = Instantiate(...);
var whatever = instance.AddComponent(...);
whatever.init(...);```

I'm assuming the issue is with wanting to initialize the component using the constructor where instead with components this would have to be done afterwards - in some sort of method.

[worthy fable]

I think I was confused by not being able use Start() method and not knowing where to assign those script references.

[vale bridge]

Is this a good way to fire weapons? For context I have an inputmanager script that uses the inputActions feature. Gun will be on a child of the player

private void Start()
    {
        gun = GetComponentInChildren<Gun>();
        if (gun)
            onFoot.Shoot.performed += ctx => gun.FireWeapon();
    }

I didn't want to do the input.getKeyDown directly in the update script for the weapons

[cosmic rain]

You might get errors if the object is destroyed. You probably need to unsubscribe from the event properly.

And having it subscribed as an anonymous method makes it difficult.

[vale bridge]

I'll do it explicitly then, thanks for the input!

Can you get a broadcaster like the gun is in this scenario to unsubscribe all the observers?

Is that possible?

If not how do you usually go about unsubscribing the observers in case an object is destroyed

[cosmic rain]

Each observer would need to unsubscribe itself. Somewhere in OnDisable or OnDestroy

[wary coyote]

Something completely inexplicably is going on in my unity project and I am not sure how to diagnose it let alone fix it.
The problem: An attribute is no longer drawing in Inspector when I booted my project this morning. Now its just gone from inspector. No console errors, compiles just fine, but its gone.

Things ive done to try to fix it:

• Restarted unity, restarted my PC, reimported all assets, deleted the library and cache, a cloned new version of the github repo from scratch, reinstalled that version of unity from scratch

A friend was able to pull my repo and its there for them but its not there for me

I've run out of things to try to get this working, I rolled back to earlier commits in the github to a time when I know 100% it was working, and its no longer working

The inspector attribute that is broken was also broken in a brand new project made from scratch that I ported just that code into, except its NOT broken in this other project, and its not broken in the github pull my friend did of the same version where it is broken

What else can I do? How do I fix this?

[leaden ice]

Maybe share the code for the property drawer?

[wary coyote]

Sure, it hasnt changed in months though so I am not sure how its relevent given that nothing about it has changed so for it to suddenly stop working despite unity not changing variables and not being rewritten or anything else occuring

using UnityEngine;
using System;

[AttributeUsage(AttributeTargets.Method)]
public class ButtonAttribute : Attribute
{
    public string ButtonName;
    public RectOffset Padding = new RectOffset(5, 5, 3, 3);


    public ButtonAttribute(string buttonName = null)
    {
        ButtonName = buttonName;
    }
}   ```

Attribute, and drawer:

using System;
using System.Reflection;
using UnityEditor;
using UnityEngine;

#if UNITY_EDITOR
[CustomEditor(typeof(MonoBehaviour), true), CanEditMultipleObjects]
public class ButtonAttributeDrawer : UnityEditor.Editor
{
    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();


        var mono = (MonoBehaviour)target;
        var type = mono.GetType();

        foreach (var method in type.GetMethods(BindingFlags.Instance | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic))
        {
            var attribute = (ButtonAttribute)Attribute.GetCustomAttribute(method, typeof(ButtonAttribute));

            if (attribute == null)
                continue;

            string buttonLabel = method.Name;
            if (!string.IsNullOrEmpty(attribute.ButtonName))
            {
                buttonLabel = attribute.ButtonName;
            }

            GUILayout.BeginHorizontal();
            GUILayout.FlexibleSpace();

            GUIStyle style = new GUIStyle(GUI.skin.button);
            style.padding = attribute.Padding;

            Vector2 size = style.CalcSize(new GUIContent(buttonLabel));

            if (GUILayout.Button(buttonLabel, style, GUILayout.Width(size.x + style.padding.horizontal), GUILayout.Height(size.y + style.padding.vertical)))
            {
                method.Invoke(mono, null);
            }

            GUILayout.FlexibleSpace();
            GUILayout.EndHorizontal();
        }
    }
}
#endif```

it makes a button of a method if you put the [button] tag over the method. Its not about what it does, its about why did it randomly stop working all on its own suddenly despite nothing changing, I feel gas lit

Its immensely confusing that the buttons appear on other people's pulls of my repo and not on mine

[quartz folio]

1. Is your inspector actually running

[twilit scaffold]

Why does it not show me where Config is coming from, like it shows me this information..

is this a configuration problem, or am i just expecting too much from VS?

Even if it just showed me the Defnition Peek, or even just the File it is coming from, on hover, that would be very helpful to my failing memory as i learn this stuff

[latent latch]

Been testing some scenarios using physic queries (specifically OverlapSphere), and I've noticed that applying a layer mask to filter out colliders doesn't actually increase the performance of the query. I've double checked and made sure no colliders were being added to the designated array, so it's not like the mask it being applied incorrectly. So, is that just the nature of these queries or perhaps there's something else I'm missing here.

[dawn nebula]

Are there enough objects to see a noticeable difference?

[latent latch]

is 100k enough

[dawn nebula]

Probably, ya.

[latent latch]

very little difference from collecting the colliders vs not* populating the array

probably going to make a test for distance collection of colliders and see how well that performs now

[dawn nebula]

Are you using the non-alloc version too?

[latent latch]

ye

[dawn nebula]

🤷‍♂️

[latent latch]

it's being tested on a per frame basis, so gc less of a problem

[dawn nebula]

another mystery of the engine

I guess it really depends on how physics queries are handled under the hood

[latent latch]

time to render games using two cameras at different space in the world

so queries dont overlap

[lean sail]

What kind of cases did you test, like with having a lot of objects with each layer in the area?
Even if it's not faster, you still get the benefit of knowing what layer it is on, which immediately skips a layer check or let's you directly use a GetComponent call without null check if this is some forced system where a layer must have something

[lean sail]

I'm not sure exactly what info you are trying to get, but could you not just f12 to see the file it's from?

[latent latch]

Instantiated all gameobjects with only a colliders -> yielded a frame -> cast onto the area with and without mask relative to the gameobjects

[twilit scaffold]

Yeah, i can F12 to jump to the file, and i can Alt F12 to Peek Definition, but i am hoping to have it just display the filename where it came from, when i hover, instead of having to Jump to the file, or bring up peek

[latent latch]

probably should boot up some python print some data to graphs

but yeah, the benefit overall is filtering out the indices to iterate over

[lean sail]

Ah sorry not sure about that, although I dont really know if that would even be a good thing. Might be kinda laggy if done on hover and it tries to do that on stuff like Transform everytime

[twilit scaffold]

yeah, could be. thanks for the input though

[latent latch]

what's interesting though is that multiple queries in the same vicinity didn't increase linearly, so there's more going on than I thought

[lean sail]

hm is it possible the colliders weren't fully "in"? if you just yielded a frame. Like what if physics sim didnt run by that point

[twilit scaffold]

Ended up with this, for now. at least i do not have to make several key strokes, and move way up to F12
https://marketplace.visualstudio.com/items?itemName=norachuga.MiddleClickDefinition64

[lean sail]

i love pressing f12 😅 feels nice to do it like im hitting the secret decompile button sometimes

[latent latch]

not sure, but I expect everything to just work if I'm calling it directly with a query in update

maybe ill try fixed but I dont think that would matter?

[lean sail]

ah if it was every frame then that makes more sense

i misunderstood, thought it was spawn -> wait 1 frame -> check

[latent latch]

oh yeah I do wait a frame after check instantiating, just for the heck of it

just want to run the query on a frame that isn't doing any other work

[thorn stirrup]

What is a good way to solve this?

When a player is airborne and collides with a platform, their character grabs on to the the platform, and jumps on.

So if the player collides with the bottom of the platform(bottom of the box collider), an animation is triggered for the character, but their position is also moving (lerping) to the top of the platform, directly above their collision contact point with the bottom of the platforms box collider. .

If the player collides with a side of the platform/ box collider, the character locks on to the side of the platform, and lerps directly up and a small amount towards the center of the platforms top edge of the box collider

[twilit scaffold]

This did not seem to work. i am just programming a macro in VoiceAttack instead

[tall summit]

someone can help me? im hosting an api in versel free and when I use thunder client to look if is working and it is works well, but when I use in UnityWebRequest it get an error of Authorization (401). I dont understand why... here some prints.

[old linden]

Hi, how can I access a Value with key in Newtonsoft JSON? It seems I have the syntax wrong though I can see the Key I am using is correct

[thin aurora]

Instead of JToken specify var or JtokenKeyedCollection, then the type should be right

Right now it's implicitly casted to JToken

Newtonsoft does these things because the whole system is for dynamic JSON without an explicit type, to make it easier

If you actually know the JSON returned you should not use this. Do you know the JSON format returned?

[old linden]

Thanks. It's for JSON files which are planned to follow the same layout but contain totally different values. I've not used JSON before so it's all new to me

[thin aurora]

Actually, don't change JToken to JTokenKeyedCollection, because this is the base type for the collection in the foreach, so just change it to var, or try to find out what the type of a value in JTokenKeyedCollection is by looking at the definition

Looks like there is no explicit key-value pair in this https://github.com/JamesNK/Newtonsoft.Json/blob/master/Src/Newtonsoft.Json/Linq/JPropertyKeyedCollection.cs

So scratch my previous answer. What you should probably do is this:

foreach(string key in jsonArray[i].Keys) {
  JToken @value = jsonArray[i][key];
}

Keys exist as a method in the dictionary: https://github.com/JamesNK/Newtonsoft.Json/blob/master/Src/Newtonsoft.Json/Linq/JPropertyKeyedCollection.cs#L205C36-L205C40

If you can't get Keys like this make sure to cast it to a JTokenKeyedCollection first

[old linden]

Thanks but I'm iterrating over a JArray not a JPropertyKeyedCollection

[thin aurora]

But the entry in this array is a Dictionary right? You wanted the key of these?

That's what I assumed judged by the image you shared

[old linden]

I'm not exactly sure. All I know is I have a JArray and I'd want to get access to the Values with the Keys in the debugger 😦

[fervent furnace]

I wonder why you cant make a poco in c# side….

[thin aurora]

But where are the keys here? I'm confused what exactly you are trying to read

Do the keys and values exist in the array?

[tall summit]

someone?

[old linden]

@thin aurora
Hmm. Here is my Json file and more of my code. I'm trying to return the "Item" fields value as shown in the image. JArray jsonArray is the groups of fields I get using sheetname which is set as "Export Master" for now. Apologies I am a little useless with the entirety of json

[thin aurora]

So this is an array of objects, where an object can also be null

[old linden]

Yes, though the check near the top should account for that

[thin aurora]

Then you should just iterate the array, and each entry has a "item" property you can check

When iterating you get this: https://www.newtonsoft.com/json/help/html/t_newtonsoft_json_linq_jobject.htm
Then just get the item by using this: https://www.newtonsoft.com/json/help/html/P_Newtonsoft_Json_Linq_JObject_Item_1.htm

Can you share the !code through a text editor?

.Item[string] property is for a JObject, but I have a JArray 🤨
Sure give me a min

[thin aurora]

You first iterate the array with a for or foreach loop, and then you do arrayEntry["item"]

The JObject will then return the value as a JToken, and you can then get the value from this using Value<T>

T being string in this case

[chilly surge]

Do you know the array is always named Export Master? I think someone already answered you before that if you have specification of the format, you wouldn't need to manually traverse the JSON with dynamic API.

[thin aurora]

I don't think it is judging by the variable but this is better answered by them

[old linden]

@thin aurora

[old linden]

The name is a fixed string in the editor, I got around that 🙂 thanks

[lean sail]

whats the use case of this if you dont mind as well? because if you had a class that contained the needed fields, this would be a very simple 1 liner

[chilly surge]

If you know it's a fixed string, you can just make a class and tell it to deserialize into it rather than manually traverse.

You are basically reinventing (the most used part of) Newtonsoft.

[old linden]

No it has the possibility to change but I waiting on someone to get back to me about how the structure will be. I am looking at the worst case for now :/

Working for a company which has no idea is bad haha

[lean sail]

if there is possibility of change, then you cannot guarantee the field will be named "Item" forever, thus this breaks as well

[thin aurora]

JObject json = JObject.Parse(File.ReadAllText(Path));
jsonArray = json[sheetName] as JArray;

if (jsonArray == null)
    return;

foreach(var entry in jsonArray)
{
    var item = entry["item"].Value<string>();
}

This might also work

JObject json = JObject.Parse(File.ReadAllText(Path));
jsonArray = json.Value<JArray>(sheetName);

if (jsonArray == null)
    return;

foreach(var entry in jsonArray)
{
    var item = entry.Value<string>("item");
}

Keep in mind all of this is dynamically generated and there is no guarantee these things exist, so you should always apply proper null checking in the event the json ends up different

[old linden]

Thanks a lot. So to clarify because this is totally new to me. entry is represented as a group of fields?

[thin aurora]

Also, can the array entry contain different data or is this always the same?

[thin aurora]

That's just the name I gave the variable representing the array data

[old linden]

The more I look at this, the less likely I am going to suggest it for my project. The company effectively want something with a non-fixed layout which I see won't work

[thin aurora]

What exactly in this json can vary in terms of naming and data? The whole system should only be like this if the JSON is varied, but what exactly is varied here?

You could probably cut off a lot of this parsing if the data is always the same

[old linden]

Literally everything

Sheet name, list of fields, their names

[thin aurora]

Right then I doubt this can be done any better unless you can serialize it in a class where data is nullable

[old linden]

Ok thanks

[lean sail]

thats a design problem from the start imo, what would such layout accomplish? its not like you'll generate a new class with fields at runtime to even hold the data

[old linden]

Yup 🙂 Now that I know its not possible, gonna let them know.

[thin aurora]

It's kind of possible, it's just a lot of work when the JSON varies

[old linden]

Yeah. I don't payed enough to make that system haha

[lean sail]

you can parse the data, but you wont use it

[thin aurora]

So generally you should not do that unless it's simple, like two different objects being part of an array

Anything more complex should perhaps be reconsidered

Yesterday I had to parse incoming data from Typescript, which is a lot more flexible when it comes to types, but this becomes a ton more complex in .NET

So I'm also going to change this around a bit probably

[lean sail]

im still super curious at what they were planning for this 😅

[old linden]

So we have a bunch of scenes loaded dynamically by a single project at runtime. They want to use JSON for scenes which have customsable data. So in the example of my Json file i shared, it was a supermarket with products, prices, weights and cost etc. The company either doesn't know or won't tell me what else they want to do with it but they said it must be able to adjust dynamically for different json layouts 😂

As you can imagine they have 0 technical knowledge

[lean sail]

i was actually typing something like that in my message above as a joke and deleted it, "a game built on json"

[old linden]

lol

[old linden]

We're not done yet 😂 I got this error

[thin aurora]

Sorry, my experience with this got rusty after a while

[old linden]

No worries

[thin aurora]

This means that some variable ended up being a JValue, which you can't get another vlaue from unlike a Jobject

What is line 59?

My guess it's entry["item"].Value<string>(). Try entry.Value<string>("item"); instead

[frail dust]

hey there, anyone having good hands with Poisson Disc Sampling in unity? I need help

[thin aurora]

Please ask your question instead of asking to ask

[frail dust]

alright

[craggy veldt]

is there a timer that's frame-rate dependent ? similar to Time.realtimeSinceStartup but that obviously would not slowing down if I forcefully lagging the game.
Of course we can roll our own elapsed time via deltatime, but hoping for something built-in instead

[late lion]

That is frame-rate dependent? I.e. if the game is running at 30 FPS, the timer would increase at half the rate of 60 FPS?

[craggy veldt]

huh, pretty sure I tested this 🤔.. let me check once again. Thanks!

[frail dust]

how do i even judge that whether the problem is a general problem or advanced or even a beginner

[knotty sun]

use some common sense. the categories are more about your skill/knowledge level than your problem

[frail dust]

no reason to be rude dude. The last time I posted a question in advanced thread, someone pointed out that it shouldnt be an advanced question

[knotty sun]

rude? why was that rude? I was just answering your question

[frail dust]

I found it a little rude. But Alright

[late lion]

I only asked questions to clarify. I'm not sure what else you interpreted from my message.

[eternal dome]

Why is the function called only at a certain angle and not constantly when you touch the collider? The code seems to be correct

        RaycastHit2D[] hits = Physics2D.CircleCastAll(transform.position, grabRadius, Vector2.right, 0);
        for (int i = 0; i < hits.Length; i++)
        {
            item item = hits[i].collider.GetComponent<item>();
            if (item != null) 
            {
                item.InRadius(true);
                Debug.DrawLine(transform.position, item.transform.position, Color.blue);
            }
            else
            {
                foreach (item _item in GameObject.FindObjectsOfType<item>())
                {
                    _item.InRadius(false);
                }
            }
        }
``` Code that calls a function in a radius

[frail dust]

Maybe because your player's collider might be touching your hoe's collider (A case in which your collider is a little bigger than your player)

Can you show your player's properties?

[quartz folio]

You should be using Overlap functions if the distance of the cast is always going to be 0

[frail dust]

show the collider of player as in scene view

[frail dust]

alright

what does the blue circle do?

the big blue one

[eternal dome]

Can you give me an example, I don't understand what it means?

[eternal dome]

the radius from which it can reach the object

[frail dust]

u got that right. Your circle collider of player is not bigger than the player's character. So your collider touching hoe before the player isnt the issue

[frail dust]

wdym?

[eternal dome]

it works not by triggers but by raycast

that is, the player's collider will not affect this in any way

[frail dust]

so does this mean that whenever an item is in that blue circle, then only the player can interact with that?

[frail dust]

yes

[eternal dome]

yes

[frail dust]

got it

[eternal dome]

This happened when I added several layers of tile maps. Maybe it has something to do with

[frail dust]

What do you mean when you say that it gets called only at a certain angle? I saw the video but didn't understand the actual issue. Can you elaborate?

[eternal dome]

When an object is in a blue circle, and a blue line stretches to it, it means that a function within the radius should be called. And this does not happen only if you find a certain place

[frail dust]

I see

[versed spade]

Is there a better way to store object data for access in a CS script

Don't want to wastefully make an object just to call these values

[heady iris]

There are two options here

• make a plain old C# class and mark it with [System.Serializable]
  • This isn't a Unity object, so it can't be referenced. You just directly embed it into something else.
• make a ScriptableObject class and create assets to store instances of it
  • This is a Unity object, so it can be referenced like a MonoBehaviour or GameObject

Use the latter if multiple things need to share a reference to the same data.

Use the former if it's always (or almost always) unique

[cerulean zealot]

hi! is there a way to report a BSOD bug on this discord server?

[mental rover]

BSOD's are OS level critical errors, unlikely to be relevant to Unity specifically, but you might get some traction in #💻┃unity-talk if you think it's related

[cerulean zealot]

The windows is new and the components the same

[hard viper]

this has nothing to do with Unity or Discord

that is an issue with windows

and even if it were a Unity issue, it would still not be a code issue, which is what this channel is about

[cerulean zealot]

I see, thanks

[heady iris]

It could be a GPU problem that Unity reliably triggers.

But that would still be something that should be reported elsewhere

[faint tree]

is there a way to access files outside the plugin folder, from inside it?

im using an asset for fingerprint scanning and when it succeeds i want to call a method on my main class but it wont let me import it

[leaden ice]

Much better not to try to modify the plugin if possible

Typically such a library would include a way to handle the completion of scanning the fingerprint

Are you sure you're not missing something?

e.g. some kind of onComplete event, or an isCompleted property somewhere you can check.

[faint tree]

thanks for the help. yeh theres an Action successHandler which is called when my fingerprint is scanned successful, so to proceed i want to call fingerPrintScanned() on my main app class, but i cant import it to call that

[leaden ice]

you mean successHandler is a parameter you pass in to the scanner method?

[faint tree]

i see, how would i subscribe to it?

[leaden ice]

It's unclear

is it a parameter?

Or an event somewhere?

I would need to see how it's set up

if it's just a parameter you pass in - then you should simply pass in your callback and call it a day

[faint tree]

its like

    "Flow Valet Authenticate", "Unlock with finger or face", () =>
{
  
    // success
    MessageText.text = "success" ;
    _("SUCCESSFULLY UNLOCKED");
    
},

[leaden ice]

Ah yeah then you just pass in your thing there

jBiometricScript.StartAuthenticate( 
    "Flow Valet Authenticate", "Unlock with finger or face", () =>
{

    myMainClass.fingerprintScanned();

}```

[faint tree]

hmm, i cant import myMainClass, and that code is inside the plugin, i guess i could move that code into my main class

[leaden ice]

wdym this code is inside the plugin?

Where are you calling this from?

I'm trying to understand the interface between your code and the plugin code

[faint tree]

the code i pasted is inside a .cs file inside assets/plugins

[leaden ice]

is this code you wrote inside the plugin, i.e. you already have been making changes inside it?

at some point in your code you are accessing the plugin somehow, no?

[faint tree]

well i was attempting to hack in a line like u said myMainClass.fingerprintScanned();

[leaden ice]

yeah but like

[faint tree]

no im not accessing it from my main code

[leaden ice]

how are you even starting the fingerprint scan FROM YOUR CODE

[leaden ice]

how is that possible?

You have to be, no?

[faint tree]

i copied the sample scene objects into my scene file

[leaden ice]

oh that's just example code

[faint tree]

which contains a button to start it

[leaden ice]

yeah you don't want to modify that

it's just an example

write similar code in your own scripts

[leaden ice]

like this - you can make your own button that does this

it's just an example

samples are meant to be samples. They're not meant to be used in your project directly

[faint tree]

ah, i usually just bring them in and hack them a bit

🙂

ill try it cheers

awful that u cannot import easily

[leaden ice]

you['re not meant to change the asset itself >_>

[faint tree]

yeh but i nearly always do lol

[leaden ice]

bad habit

[faint tree]

yes i suppose it is, for when u update it etc

[crisp bronze]

Hi, I'm trying to create a random level generator that uses prefabs and spawns them on a grid based on their proper entrances. Each spawned prefab should be chosen based on having a door that connect to the previous entry direction, and also based on its next available exit point. At the moment, I'm having trouble with making sure that the prefabs don't spawn on top of existing ones. Any ideas?

Here are my scripts so far:
LevelGenerator - https://github.com/jungaboon/JungaBoon-Utils/blob/main/Scripts/LevelGenerator.cs

LevelSegment - https://github.com/jungaboon/JungaBoon-Utils/blob/main/Scripts/LevelSegment.cs

[leaden ice]

Well it really depends on the nature of these rooms

are they all the same shape?

[hard viper]

Is there a way to make a property drawer for a generic class? I have EnumerableArray<TEnum, TStored>, and when the field is serialized, it is given a concrete type

[crisp bronze]

Yup, they're all just 20x20 unit probuilder blocks to test

[leaden ice]

Then can't you just check if the block you are testing is already built on?

you say "to test"

what will it be in the final thing?

Will they be arbitrarily shaped 3D rooms?

You would probably benefit from some kind of regular grid system here

[jagged snow]

If you want to limit the scale of an object based on distance. Do you limit the distance or the scale?

What I'm trying to do is basically clamp the size of a floating text. When the camera is close I want it to stay at a certain size and vice versa

[heady iris]

you'll want to vary the scale when the distance is below a lower bound or above an upper bound

I think you'll just do this:

float distance = Vector3.Distance(transform.position, viewer.position):
float scale = normalScale;

if (distance < lowerDistance) {
  scale *= distance / lowerDistance;
} else if (distance > upperDistance) {
  scale *= distance / upperDistance;
}

I feel like this is missing something, though...

It makes sense up close. If it's halfway to the lower limit, you halve the scale.

But I'm not sure about the upper limit. It feels like I should be subtracting something here. Not sure.

But you could give that a try.

[faint tree]

@leaden ice works great now, thanks dude... fingerprint and facescan, very cool!

would be good if u could update the biometric data by downloading it for different users etc,

[jagged snow]

thanks ill give it a shot this is what i have atm.

    {
        float scale = Mathf.Clamp(_distanceFromCamera, minCalculatedDistance, maxCalculatedDistance) * _scaleMultiplier;
        transform.localScale = Vector3.one * scale;
    }```

[jagged snow]

what exactly does normalScale variable refer to?

[heady iris]

It'd be the scale of the object when it's between lowerDistance and upperDistance

so it's the "true" size of the object, I suppose

[jagged snow]

ahhh so you mean

Using this formula im able to get a consistent viewing scale throughout

[heady iris]

This will give you a consistent size at all times

if you double the distance, you double the scale

[jagged snow]

right but using your code which sets bounds that will limit it at some point right

[heady iris]

I thought you were looking for something more complex, whoops

[heady iris]

If you just need a constant apparent size at all ranges, then this is all you need

[jagged snow]

i actually dont want a certain size, it's more so that i dont want the text to become smaller when too far away and too big when close

I want to clamp the size at certain ranges, that would be a better question. Like the size of the text at 40 distance would be the same as it would be at 90

[heady iris]

okay, so you do want this, then -- it rescales the object when it's too close or too far

[jagged snow]

right so what i need to think about is how to get the exact scales of those targeted disance. the exact value of both min distance and max

[faint tree]

anyone use a qrcode scanning asset? just wondering which ones work well

[heady iris]

You could flip it around and check if the object's apparent size is too large or too small

Take the ratio of the current distance to a reference distance (say, 10 meters)

That's how much larger or smaller the object looks than at the reference distance.

[jagged snow]

Im going to try this first. Everything functions normally until a certain distance is met. To not complicate things at the start ill just have it detect if the text is too far. Once it reaches this point enable the scale formula.

[hard viper]

my attribute cannot take the type of my generic argument, but it should be hard coded to the concrete class. Any workarounds?

[mossy snow]

are you sure? that looks like a syntax error to me

[heady iris]

yeah, it looks like it has to be known at compile time (well, more than that, it needs to be a constant for this class)

I presume this is being used for some custom editor/property drawer code?

[hard viper]

yes

I have an EnumerableArray<TEnum, TStored> class which just maintains a strictly held array that relates an enum to TStored

[heady iris]

You could inspect the actual type with reflection.

[ashen yoke]

generics are generated at runtime, attributes are baked into meta on compile time

[hard viper]

ok, I'll see. I'm not very good at reflection tho\

[ashen yoke]

https://learn.microsoft.com/en-us/dotnet/api/system.type.getgenericarguments?view=net-8.0

[heady iris]

As long as it's always a TStored[] and not some arbitrarily complicated mess of generic types, it should be alright

[hard viper]

I'm honestly so lost right now, idk how to work with editor scripts.

[heady iris]

One important thing is to learn the division between:

• unity's serialized data
• the actual runtime objects

[hard viper]

I did get some code sent my way for a NamedArrayAttribute which I got working. The issue is idk how to reference the thing that the editor script is targetting

        // Replace label with enum name if possible.
        var config = attribute as NamedEnumArrayAttribute;
        string[] enum_names_compact = System.Enum.GetNames(config.TargetEnum);```

this is some of the code I got, and it works if I can get that target enum. But idk how to target the thing that I'm tied to

I think I might be able to take it from there if I could

[heady iris]

arrayElementType will give you the string name of the elements stored in a serialized array, which isn't quite what you need

[hard viper]

EnumerableArray contains an array, and I'm trying to give it an attribute, but I don't think this is enough information because the array doesn't know rthe enum

[heady iris]

https://docs.unity3d.com/ScriptReference/SerializedProperty.GetArrayElementAtIndex.html can fetch a single SerializedProperty from an array

but that's just going to give you a SerializedProperty holding an integer

[hard viper]

I can call isArray etc

but I need to know the type of the enum, which isn't in the array

[heady iris]

I'm kind of a novice here too, so this might be wrong.

I think you need to grab the serializedObject from property, then get targetObject and get its type.

Then you can search for a field whose name matches that of the original property and check its custom attributes for your NamedEnumArrayAttribute. You should also be able to figure out the generic type by fetching FieldType from the FieldInfo for the field.

Quite a mess.

You should ask about this in #↕️┃editor-extensions

[glad plinth]

Is it possible to calculate the "FPS" of this texture?
as that would be the FPS of the cloned screen

[rigid island]

textures dont have fps wdymm..

[glad plinth]

This texture kinda technically would as its a screen mirror it updates to mirror your IRL screen

is there a way to get how frequently its doing this?

[leaden ice]

doubtful

but probably depends on this actual script or component or whatever

It's likely just reading some texture from a native buffer somewhere once per Unity frame

It's not likely caring or recording how often the "source" of that frame data is writing to the buffer.

[visual wolf]

i have 2 public double variables, i want to save them to a file and load them. i am thinking about using playerprefs, is that possible? I read somewhere that i'd have to convert it to a string to save it, and back to a double to load it.

[glad plinth]

Done 🙂
Just opened the Texture controllers cs file and When "UpdateMaterial()" was called added a FPS Counter outputting to console 🙂

[rigid island]

just save it as json , put whatevr you want in it

[leaden ice]

PlayerPrefs only supports float yes. So either:

• Save it as a float (and accept the loss of precision)
• Save it as a string
• Don't use PlayerPrefs at all

The third one is probably the best tbh

Make a proper save system

[visual wolf]

how do i do that 😭

i started unity only about a month ago so i'm fairly new, i'm not sure how to make a proper save system yet

i only need to save like 3 doubles

[rigid island]

its pretty simple, make a data object then serialize it using something like JSON utility so you can save it as json string with File.WriteAllText for example

[visual wolf]

data object?

[rigid island]

like a regular object, class

[visual wolf]

oh

[rigid island]

public class SomeData
{
    public double myDouble;
    public double myotherDouble;

}```

[visual wolf]

oh

that seems quite easy

is that it?

and then serialize and whatnot

[rigid island]

well you have to store data inside an instance of this then use JSON UTIL + File.IO

 public static void Save(SomeData data)
    {
        var stringData = JsonUtility.ToJson(data);
        var path = Path.Combine(Application.persistentDataPath, "theFile.data");
        File.WriteAllText(path, stringData);
    }

[visual wolf]

and then what?

[rigid island]

thats pretty much it

you read it, do the inverse

[visual wolf]

really?

[rigid island]

yes its dead simple

[visual wolf]

wow i thought it would be a lot more complicated lol

can you do File.ReadAllText ?

[rigid island]

indeed 🙂

[visual wolf]

alright, i'll try get this done tonight, thank you very much for your help!

[rigid island]

sure thing! lmk if you have any issues

[visual wolf]

hey would it be ok for me to dm you?

[rigid island]

Nah I dont have DMs open

[visual wolf]

alright lol

[rigid island]

you can reply me here or make a thread

[visual wolf]

ok, so i'm just super confused 😭

[rigid island]

oh alr. make a thread , I'll explain

[hard viper]

when throwing errors, is there a way to make my error have a string for the file + line of code for a given line that is being evaluated?

[past tapir]

your debugger can

also your console in Unity already shows the file, line # of the error

[hard viper]

that's not good enough

I am throwing an error on an invalid save. I am referencing things through an interface. The interface has a method to output a string with error message if it fails a check. These methods are only supposed to return true/false with out of an error message, and not necessarily throw.

I need to append the file+line# to the string of origin.

[somber tapir]

I use this AnimationCurve to calculate the required exp, but once the player reaches the "estimated max level" the required exp no longer increases. Is there a way to have the curve go on infinitely?

[chilly surge]

Not sure if these work in Unity, worth a shot: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/attributes/caller-information

[past tapir]

can you do Debug.Log($"Your GameObjecT?: {transform.parent.gameObject}");

you can also try "Ultimate Editor Enhancer" it will put a (!) on any game object that throws a error

https://infinity-code.com/assets/ultimate-editor-enhancer/trial

[latent latch]

The curves themselves are just plotting points, there's no real formulation going on, so if you want values that aren't plotted then that's something you need to start formulating.

It's not like you've some linear values to just plot that easily either, so if you do want this exponential gain then that's something you'd have to put together and plot dynamically, or just throw the equation in code.

[hard viper]

i'll check it. ty

[heady iris]

Evaluating a point past the end of the curve gives you the same value as the end of the curve.

An exponential function for EXP per level is pretty simple.

or maybe something polynomial

Desmos is great for playing around with functions for this purpose.

[magic wolf]

Dumb question. How do I change the scale of an animation? I have a player object with several animations. Walking jumping ect. Well when he is idle he is normal size but as soon as it uses another animation he grows to about 2.2 times the normal size

[heady iris]

Did you make these animations yourself?

If not, did they come from different places?

[magic wolf]

No

They all came from the same sprite sheet

I didn't personally make them but they were made for me

[heady iris]

ah, these are sprite animations

can you adjust the pixels-per-unit on individual sprites sliced from the same image? if so, that might be the issue

(i've just recently started learning 2D)

[magic wolf]

I think so

Do I lower it? or raise?

[heady iris]

make sure they are consistent

[magic wolf]

oh ok

I will try

[heady iris]

Reducing the PPU means the sprite is larger in the world

since you need fewer pixels to cover one unit

[magic wolf]

Oh you know what... I messed up

I took a week break and was mid swapping animations. Not all of them are swapped and I forgot 🙄

Sorry Im dumb

[heady iris]

Ah, that'll do it :p

[magic wolf]

Thats what happen when you sleep :p you forget stuff

lol thanks for the help haha

[spice briar]

hey, so im making a scope system for my game with variable optics, Basically, i need a way to convert a zoom multiplication (i.e. 4x scope) to the camera FOV that i need to zoom to. any ideas on how to do this>

[leaden ice]

divide FOV by the desired magnification

e.g.:

float GetFOVForMagnification(float baseFov, float magnificationLevel) {
  return baseFov / magnificationLevel;
}```

baseFov would be the FOV you consider for the "1x" zoom level

[spice briar]

makes sense, thanks!

[leaden ice]

by the way unless you need perfect physical accuracy for some strange reason, It's also completely valid just to play with the actual FOV numbers corresponding to each zoom level until it "feels right"

[spice briar]

well its intended to be a realistic shooter

[cold adder]

Hey y'all, I'm starting to design a 4 player RPG game, but I don't know where to start for game servers, anyone have any tools they'd reccommend?

[rigid island]

before worrying about game servers, do you actually have all the code / infrastruture of game done already ?

[weary swift]

Yo ! Is error handling/exception handling a useful thing to do while developing your project ?

[rigid island]

of course!

Imagine you're looking for a File to read from, but the file doesn't exist. How would you communicate that without handling a custom exception to show a neat window "Save File Not Found" or something

also you wont break the rest of the code possibly , just cause file is not found

[weary swift]

And do you remove all the error handling before making the final build of your game ?

[rigid island]

that would defeat the purpose

this isn't to say you need to make everything an error to handle or a try Get

[weary swift]

Because you may need to add features, or correct bugs or anything like this right ?

[weary swift]

Is the correct term error handling ? So I can search it effectively

[rigid island]

maybe explain what you meant

to me error handling is more important in things beyond my control

[weary swift]

Ok

[heady iris]

Exception handling is for things that are both:

• things you expect to happen
• things you can reasonably deal with

[rigid island]

eg Internet Requests, File movement / creation etc

maybe you have an Upload to internet rquest, it may work on your PC but you have to handle if case there is no connection / error

[weary swift]

Ok, maybe I didn't use the right term. What I mean is for example checking if a scriptReference is null before using it

[rigid island]

oh those are just null checks

they arent errors unless the item is null and you try to use it

[weary swift]

Ok I understand

Then my question is should I null check "everything" or should I trust myself/others to put the rights values in the code so that it works ?

Because even if there is a null error the compiler will alert me

[weary swift]

Ok, thanks ! That makes sense

[heady iris]

No, the compiler won't warn you about null references (other than trivial ones, like using something immediately after assigning a null to it)

These errors happen at runtime.

[rigid island]

ideally if you expect it could be null you want a check

[weary swift]

I meant Unity then I guess

I'm talking about the LogError that appears when there is a null reference

[weary swift]

But if the only possibility that this thing will be null is if humans did an error while creating the object or assigning wrong values, etc... In this case should I check for null or not ?

I think that's precisely my question

If I understand what you said, I should null check if I can do something with it right ? If not then I just let Unity LogError

[neat forge]

This is mostly a question of coding style/philosophy

[rigid island]

are you talking about co-writers / coders?

[weary swift]

Yes

[rigid island]

always check something that mayb null before you try to use something yes

but if you know it wont be null there would be no need ofc

[weary swift]

But, if the only possibility that it is null is because a human made an error while giving the reference to the script in Unity inspector for example. In this case, should I check ?

[wicked scroll]

1. is it likely someone will make that error?
2. if someone does make that error, how long will it take you to figure that out?

if neither of those things are big issues for you, i say avoid null checks and just let stuff error, then fix the errors

[weary swift]

Ok, makes sense

[neat forge]

In my opinion, "failing loudly" is the way to go. If you're giving a method a parameter and you null check it and it does turn out to be null, but the method needs this parameter to do its work, what are you going to do? Just silently not do it? Then you're just making your bugs harder to find

[wicked scroll]

there's also the 'null object pattern' which can be useful so that you never really have nulls

[rigid island]

@neat forge well yeah, just depends what that object is

if you have private List<string> myList = new()
obv you dont need to check myList being not null because it always guaranteed it wont be

[weary swift]

I'm going to give a concrete example. I have an animation for a weapon and have two floats, one is the "hitBoxStartTime" the second "hitBoxEndTime", theses two floats are time contained in the animation that tell me when the hitBox should be enabled and when the hitBox should be disabled. Ofc the Start should be less than the end.
So I wrote this :
if (!(attackAnimationData.hitBoxStartTime < attackAnimationData.hitBoxEndTime))
{
Debug.LogError("HitBoxStartTime should be less than HitBoxEndTimer.");
yield break;
}

But I feel like it's serve like no purpose, the only case in which this would happen is if a human made an error while declaring the variables.

This isn't a null check but I guess it's in the same ideas

[knotty sun]

spoken like a true game dev. In app dev that approach would be fatal

[weary swift]

Gonna search about this thanks

[wicked scroll]

are the variables 'declared' or filled in via the inspector? for validation stuff like that, often it makes sense to just validate the input fields at 'design' time rather than having the core game worry about user error

[weary swift]

filled via a scriptable object

[weary swift]

Yes, that's exactly what my question was about. Then I guess I have the answer thanks !

[wicked scroll]

yeah, for something like that i would say to do validation in the SO itself so that by the time that data gets to the game, you know it's correct (and so that you can do stuff like have a message saying HEY YOUR VALUES DON'T MAKE SENSE at design time when it's useful)

'creating content for your game' and 'running your game' are different contexts and you can totally take advantage of that

[weary swift]

So, while creating content for my game, let's say in this case creating attack animations, I should make some Debug in case I fail in the design process. But when the design process is finished, I should remove these because they serve no purpose anymore right ?

Or I can just trust myself that I don't input wrong values

It's just preference ?

[wicked scroll]

i would consider that design is never really 'done' and that it's wortwhile to assume that maybe some day you'd want to change a number or whatever and have your validation still be in place

it doesn't hurt anything to keep it in there since it's all 'editor' stuff

that said, if you are doing lots of logs that would get annoying and i would prefer using something like https://github.com/dbrizov/NaughtyAttributes to add more useful validation

[knotty sun]

There is Editor code and Runtime code, just make sure the validation is in the Editor code

[wicked scroll]

there's also compilation hooks you can use to check that certain values are filled in/valid/etc when you do a build

[weary swift]

I don't know about this, I will search about this thanks !

[weary swift]

In the NaughtyAttributes extension ?

[wicked scroll]

built into unity

[weary swift]

Ok, thanks for all the answers guys ! Really helpful, I appreciate this.

[heady iris]

could you elaborate on that?

[wicked scroll]

sure, you can implement this interface: https://docs.unity3d.com/ScriptReference/Build.IPostprocessBuildWithReport.OnPostprocessBuild.html
and then do your validation via the asset database or whatever

if you find something wrong you can throw a BuildFailedException and it'll abort your build with the error

so you can do stuff like make make sure your config assets are properly filled in or whathaveyou

[heady iris]

I currently have some editor scripts that do exactly this. I just run them manually while I work, though

I guess it'd be nice to run that before the build, though :p

that'd be IPreprocessGroupWithReport, then

[wicked scroll]

oh yeah there probably is a before one too if that'll work for your (i imagine it would for most cases)

[heady iris]

Definitely looks useful -- I have a few things I'd like to be a hard fail

like a scene that my game lets you visit not actually being in the scene list

[wicked scroll]

yeah! i don't use it much since mostly it makese sense to validate things more...in-place? but where it's nice, it's nice

[heady iris]

this has made new features a lot easier to set up for all of my existing entities

(when the new feature results in serialized fields appearing on existing components, that is)

ideally most new stuff is just a new component

[hoary sorrel]

I'm having an issue where my game works fine in the editor, but when I build it, a lot of the references stop working, and the game becomes unplayable. Enemies are no longer killable and the game over screen no longer displays half of the required elements.

[latent latch]

good time to learn to implement an in game console

[rigid island]

use onscreen console

[hoary sorrel]

how would i do that?

[rigid island]

thers an asset

[hoary sorrel]

can i have the link?

[rigid island]

https://assetstore.unity.com/packages/tools/gui/in-game-debug-console-68068

[hoary sorrel]

thank you

[rigid island]

check console for errors

[hoary sorrel]

Turns out the problem isn't with the references, in fact there are no errors in the build version at all. Now I'm really confused.

[golden garnet]

Does anybody happen to have any answers for this?

[rigid island]

You'd have to show more info

like code

setup

etc.

[rigid island]

are you sure its not just a UI / Resolution issue

[golden garnet]

I could send a video, if that helps?

[rigid island]

yes but code would probably help..

[hoary sorrel]

Part of the issue could be that, but enemies aren't dying and that's definitely not a UI issue.
The other weird thing is, when I build the game, it works almost completely fine the first time I run the application but breaks down the next.

[rigid island]

depends how you do clicking on enemies

[hoary sorrel]

would a video of the issue help?

[rigid island]

wouldnt hurt also sharing how you do click on enemies etc

[hoary sorrel]

can you explain what you mean by "click on enemies"?

[rigid island]

oh sorry i read Killable as Klicable

dyslexic af

[hoary sorrel]

all good

[golden garnet]

https://hastebin.skyra.pw/hetituruse.csharp
Video and code associated with navigation issue.
In the video, you see me jump onto a rock, which because of its height, causes the boss to freak out. I'm not sure why this is happening but it has something to do with the height of the player.

[hoary sorrel]

the green ones are supposed to die in 3 hits, the yellow ones in 1. the error in the top left is a problem with accessing the high score txt file, its not my main concern right now

[rigid island]

mate, you have errors building up

how can you say "No errrors"

12 errors by end of video

[hoary sorrel]

because its constantly accessing the high score document

i'll show you what the error log looks like

[rigid island]

so how do you know that is not breaking the rest of the execution

[hoary sorrel]

i've commented out the lines causing the errors before, no difference

just a whole bunch of that

[rigid island]

why is it looking in System32..

anwyay its happening mid killing enemy at some point

so you have to show that method

[hoary sorrel]

idk tbh i'm using system.io.file.read

    private void Start()
    {
        highScore = System.Convert.ToInt32(System.IO.File.ReadAllText("highScore.txt"));
    }
    public void updateScore(int amount)
    {
        score += amount;
        scoreText.GetComponent<Text>().text = "SCORE: " + score.ToString();
        highScore = System.Convert.ToInt32(System.IO.File.ReadAllText("highScore.txt"));
        if (score >= highScore) { System.IO.File.WriteAllText("highScore.txt", score.ToString()); }

heres another video showing the functionality in the editor, for comparison

[cold adder]

I do not, I figured that the service I use could change how I approach it

[rigid island]

Nahh game Servers is the last of your worries believe you me

[rigid island]

can you show the method that supposed to destroy / kill enemy

[hoary sorrel]

yeah

    void enemyDie(int scoreChange, bool heartDrop)
    {
        if (!enemyCountUpdated)
        {
            spawnerScript.enemyCount -= 1;
            enemyCountUpdated = true;
            logic.updateScore(scoreChange);
            int rng = Random.Range(0, 9);
            if (rng <= 1 && heartDrop) { Instantiate(heart, enemy.transform.position, enemy.transform.rotation);}
            if (heartDrop) { sound.playSound("enemy"); }
            Destroy(enemy, .2f);
        }
    }

logic.udpatescore is called as normal so its only an issue with the destroy method

[rigid island]

to me this just makes it more clear that if one of those is null/throw error Destroy will not reach

[hoary sorrel]

one of what is null?

[rigid island]

logic or enemy or sound

not null but if they throw error rest of code might not run

first id try making new build without logic.updateScore(scoreChange);

see if that helps then you narrowed down issue

[hoary sorrel]

alright

wait that actaully worked

[hoary sorrel]

in that case how would you go about fixing this code so it doens't read from system32?

[cosmic rain]

Either you're running your game from system32 or there's something really wrong with your environment.

[rigid island]

ReadAllText("highScore.txt") is the issue

ur not passing a good path

[cosmic rain]

Or it could just be a misleading error and it's the last directory it was checking in:
https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-openfile#remarks

[rigid island]

you should save to Application.persistentDataPath for example

this works with all platforms

[simple egret]

Also don't write to the file each time you change the score, IO operations are slow compared to other game code

[hard viper]

pretty sure those are the worst operations computers really do. worse than memory allocation

[arctic orchid]

Anyone wanna help me make a game?

Hi! Is there any alternative to animation events? I'm currently using them to enable and disable a collider who is responsible of dealing the damage. Since the animation can get cancelled the "disable collider" function might not be called. I can add a behavior to the animation state and disable the collider "on exit state". Is there any other way of synchronizing code with animations? Is there any other common workflow that is not animation events. Thanks and sorry for my English!

[compact spire]

Every time I start a new project I end up with a bunch of controllers with the urge to make them all singletons. Should I just embrace this direction or is there a better pattern to follow?

[rigid island]

depends .
I used to do that but now I for example make fields /properties Get for each manager and only need 1 singleton to access them all

using 1 thing to access many things is neater n easier to follow for me

forgot what the pattern is called, I think manager/mediator pattern or facade ?

[thick terrace]

if you want to try something totally different you could look into a container system like VContainer or Zenject but that's a fairly heavy duty solution, you kind of have to build your game around it

[lean sail]

Instead of using animation events, you can invoke your method manually with a coroutine. You can always affect the speed of the animation if you want it synced, assuming the speed ever needs to change.

[cold parrot]

The most practical pattern for small teams/solo is to have your dynamically spawned objects use a service locator to register themselves with a static system/controller (loaded with the scene) which then proceeds to inject dependencies, init state and call event handlers on the dynamic objects IoC style. If you restrict service locator usage to this lookup and keep all service registrations immutable after startup this eliminates most negatives of such global-access patterns.

[open sparrow]

Thanks a lot!

[compact spire]

@cold parrot I have a rough understanding of what your talking about, but I can't picture how that all ties together... Do you know of a good example or tutorial on that kind of setup?

[latent latch]

game manager

[cold parrot]

There are sadly no tutorials how to actually architect a game properly. Best you can find are some scattered articles under no shared keywords.

[thick terrace]

the requirements are pretty different per game too, you might go in a different direction for something very simulation and physics heavy vs a turn based game that's got a million UI screens

[latent latch]

It's like, you can make AudioManager a singleton (makes sense honestly), or keep it as a non-singleton mono and give gamemanager a reference to it

[cold parrot]

Unity doesn’t change between games though and the problems around lifecycles and IoC will be the same in any type of game

so there are a few things you can do to avoid the worst effects of singleton abuse and just overall inconsistent architecture or fighting the engine

things like zenject or vcontainer solve nothing if the fundamental issue of architecture is not understood in the team

[thick terrace]

there's always some trade offs to make though, it's impossible to get everyone to agree on the one universal best way which is why there's not much literature about it i think

[dim relic]

can someone tell me if anything is wrong with this movement script cause for some reason whenever i try to move in my game it just randomly stops and starts again and i dont know why

That is true. But still you can decide quite easily what’s a bad idea just based on scope of the project, with some minor thinking and awareness of options you have.

Posting a chunk of code like that without any logging isn't helping us here

[dim relic]

you have to press the fulscreen button next to expand

than you can see all the code

[heady iris]

Yes, it's 10KB of code with no additional information

What have you done to debug it?

[cold parrot]

People wont just digest some random code without any indication what the issue is

[compact spire]

@cold parrot Fair enough, I'll have a look around then

[dim relic]

well i used a script from dani

whenever i walk with it it just randomly stops me for no reason

like it just starts going really slow and even starts puching me back

[calm echo]

https://gameprogrammingpatterns.com/

[cunning gulch]

when i change the tiles of my tilemap programatically it doesn't affect the tilemap collider at all, is that intended?

[calm echo]

@compact spire a good first step is to avoid naming anything with manager unless absolutely necessary

[cold parrot]

The key I think is to gain a really good understanding of why global access is very bad, how to avoid it and some discipline that keeps you looking for better options. There is virtually no reason to have global access or invasive coupling to a framework for anything but the most superficial discovery. Also don’t fight the engine and use patterns that ignore the nature of unity/gamedev.

[rigid island]

iirc SetTile should automatically update the Tilemap collider

[cunning gulch]

its probably because i create my tiles at runtime (using a class which extends TileBase) isn't it?

[rigid island]

might need to make sure your tile implements this
https://docs.unity3d.com/ScriptReference/Tilemaps.Tile.ColliderType.html

https://docs.unity3d.com/ScriptReference/Tilemaps.Tile.ColliderType.Sprite.html for example

[cunning gulch]

ah yeah that works, thank you

[rigid island]

start debugging

I would just remake eevrything with Code and Tweening

I hate using animations now 😛

I like to control all my states

pls dont

[cold adder]

If they're big it usually makes it so they're expandable

I guess I'd hope they'd turn down the threshold fro that

[rigid island]

nah it cuts the lines off it says "x amount of lines remaining"

also on mobile it only shows as link to the file.txt

maybe switch it to animator ?

because it will surely making managing state easier first of all

this will be literally 1 bool on animator

basically you make a parameter is animator called Options or something

that is of bool type

[undone plover]

guys is learn.unity.com not working ?

[rigid island]

then transition between the two clips with that bool

[rigid island]

#💻┃unity-talk

this is a code channel

[undone plover]

sorry

[rigid island]

oh is working ?

I was thinking more like this

so you didnt have to use name of clips

hmm. yeah how are you starting the clips

I usually turn of also exit time for these if you want to spam and go up n down, thats why i suggested only a bool

instead of animator.Play

Hello everyone. I have been looking into mesh deformation in unity and have gotten this script. It deforms a plane mesh to curve to a sphere mesh. However when trying to apply this script to my blender face mesh, it does not work, since its built for spheres. Anyone have any ideas how I can refactor this script to work on low detailed mesh like this?

    public float hoverDistance = 0.1f; 

    void Update()
    {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;

        for (int i = 0; i < vertices.Length; i++)
        {
            Vector3 worldVertex = transform.TransformPoint(vertices[i]);
            Vector3 directionToSphere = (worldVertex - sphereTransform.position).normalized;
            float sphereRadius = sphereTransform.localScale.x * 0.5f; 
            Vector3 newPosition = sphereTransform.position + directionToSphere * (sphereRadius + hoverDistance);
            vertices[i] = transform.InverseTransformPoint(newPosition);
        }

        mesh.vertices = vertices;
        mesh.RecalculateBounds();
    }```

The video is of the script working on the sphere mesh, I just want that on the face mesh

or if anyone knows an assetstore asset that does this id just use that lol

[cosmic rain]

What exactly doesn't work..?

[wild spire]

This script cannot work on a non sphere mesh

I was wondering how I could refactor this script to work on a non sphere mesh. I dont understand the math involved so if anyone knows any resources or how to it can be done that would be great help

[lament bear]

Can I use Muse Behaviour for free?

[cosmic rain]

Is that an error message?

[thick stratus]

Hi, im trying to detect if a nintendo switch controller is the current set gamepad within the new input system and im not exactly sure what i need the if statement to equals to as documentaion and forums havent had any answers, tbh i thought something like Gamepad.current == UnityEngine.InputSystem.NintendoSwitch.NintendoSwitchProController

[wild spire]

no, it just isn't set up to work on an uneven and complex mesh like the one I am using. It only works on an evenly shaped sphere

if you increase the X or Y scale on the sphere even a little bit the mesh wont deform properly

[somber nacelle]

you would probably use the is operator to type check it since NintendoSwitchProController inherits from Gamepad and presumably Gamepad.current would be an instance of that class if that is the current type of controller

[cosmic rain]

Well, what exactly is the problem? That it doesn't project the mesh correctly? Why do I need to ask 100500 questions to get the details of the issue?

[thick stratus]

yeah no i put the wrong one haha, just the refrences act all weird as the NintendoSwitch bit doesnt exist in current context for some reason, they may have changed it or its wrong but im not sure what it is weirdly

[somber nacelle]

what exactly did you try

[thick stratus]

nvm figured it out, i tried Gamepad.current is UnityEngine.InputSystem.NintendoSwitch.NintendoSwitchProController when instead its Gamepad.current is UnityEngine.InputSystem.Switch.SwitchProControllerHID

[somber nacelle]

[mossy snow]

what are you trying to do, exactly? manipulating the mesh itself might not be the right play here. Did you look into using projectors/decals instead?
https://docs.unity3d.com/Manual/visual-effects-decals.html

[wild spire]

I’m trying to curve the eye mesh to fit the face mesh, so the 2D eye isn’t hovering. I’ve looked into decals and projectors but they were weren’t a match for this problem

[mossy snow]

I take it the eye mesh is 3D and not a simple texture then

[wild spire]

Yes its a plane

[mossy snow]

that's two dimensional. Why wouldn't a decal work for you?

[wild spire]

Decals project onto all surfaces, I want to be able to resize and move the eyes in the character creator, and decals project on top of the hair mesh or whatever else

[copper grove]

got a question
I tried lowering the M and it worked but why did a capital there ruin my whole script

[mellow sigil]

Because you already have another script called PlayerMovement

[copper grove]

no i dont

[mellow sigil]

That's what the compiler says and it knows better than you

[rigid island]

bet you do

[copper grove]

lemem check

nope

[fervent furnace]

find a script, create a PlayerMovement field, then press it and let your ide open the PlayerMovement class

[dense crow]

how can i convert from csv file into TextAsset file in unity ?.

i want to attach it into an editor tool

[mellow sigil]

CSV files are already text. There's nothing to convert

[quartz folio]

and they already are one of the extensions that import as a TextAsset

[dense crow]

but my unity keep it as defaul asset

[quartz folio]

what's the file extension?

[mellow sigil]

judging by the icon that's an Excel file

[dense crow]

it is csv

oh it worked, thanks u guys

the correct one is the book1 on the left of excel file in image.

[eternal dome]

looks like decal projector

[dim forge]

hello there,
i'll be implementing a dungeon generator kind of like the one that is used in Enter the Gungeon. This means i'll have some graph structure of rooms and will have to connect rooms to one another. But i'm not sure how exactly to represent doors in these rooms to make it easy to connect them. I thought i could have every room as a prefab, with empty objects marking where the doorways are. Then, in the script, i would just line up a door to the global location of another door to connect them. Does this sound like a good way of doing it? Below is an example of the graph that represents the dungeon in Enter the Gungeon.

[hexed pecan]

Sounds plausible to me.
Not really familiar with Enter the gungeon, are there passages between rooms or are they directly connected with doors?

[dim forge]

in the case of loops (there are 2 in the graph above) the loop is connected by generating a hallway between the first and last room of that loop

otherwise rooms are directly connected via doors

[hexed pecan]

Alright. I'd say try it and see if you run into any issues

[dim forge]

alright, thanks

[dusky niche]

How do I check if an animation has finished playing through code?

[thin aurora]

The animation provides properties for getting the length and normalized time. The animation is playing if the time is less than the length

[dusky niche]

It has to be greater than normalized time right?

[thin aurora]

Length should be the total length of the animation, and normalized time is the current time of the animation

But you can try debugging these values to see if this is truly the way to check it

[dusky niche]

there's one issue

if (this.player.GetCurrentAnimatorStateInfo(0).normalizedTime > 1 .IsName("WeaponSwitchDown")

I can't use IsName

[thin aurora]

Well not like that obviously

[dusky niche]

if (this.player.GetCurrentAnimatorStateInfo(0).normalizedTime > 1 && this.player.GetCurrentAnimatorStateInfo(0).IsName("WeaponSwitchDown") well this works

[thin aurora]

I double checked and normalizedTime is actually a bit of a weird integer

What you probably want to do is this:

if (this.player.GetCurrentAnimatorStateInfo(0).normalizedTime % 1 > 0)

For checking if the animation is playing.

The value actually holds two numbers. One for the number of loops and one for the progress of the current loop

And in this case the fractional part (0.0-0.9) is the progress

So by using a modulo like this you strip the whole number and check the fraction if it's higher than zero

Idk how the precision works here but maybe you want to account for imprecise values

Try debugging this and see if this is truly what you expect

See explanation here: https://docs.unity3d.com/ScriptReference/AnimationState-normalizedTime.html

My initial answer was a quick Google search and all these answers actually end up being completely wrong, sorry for that

[dusky niche]

normalized time doesn't seem to work
maybe because I used "this" on a script not attached directly to with the player

[weary dawn]

Im not sure where ask this but how can i add this to my project https://github.com/tonyqus/npoi

Using Unity 2022.3.18f1

And yes, i want to try making a Unity project that exports to excel

[chilly surge]

Go to their NuGet, and check their supported .NET version. If it supports what Unity supports then yes.

[weary dawn]

Is it the package name?
"NuGet’s package name is NPOI"

[weary dawn]

Im kinda new in adding packages

Found it. But what do i do with
dotnet add package NPOI --version 2.7.0-rc1

[chilly surge]

You can just click the badge:

[chilly surge]

That's how you would add it in a regular .NET project, which Unity is not (unfortunately).

[weary dawn]

dam

[chilly surge]

You can either use an assets that integrates NuGet packages if you are going to use a ton of them, or you can simply do it by hand if you don't mind it.

[weary dawn]

how do i do it by hand?

You can dm me if it will take a lot of time

if youre ok with that

[chilly surge]

Click the "download package" button on the NuGet page of the package, extract the downloaded file, and locate the .dll file of the correct architecture, then just drag it into Unity like any other asset.

[dusky niche]

well I did accordingly

{
    weapon.gameObject.SetActive(false);
}```
but even after doing so
It's not deactivating the game object

[knotty sun]

if I understand what you are trying to do you need to add some more brackets to your if to separate the or condition

[dusky niche]

it's inside of a foreach loop
so I can't do that

[knotty sun]

what? Of course you can

[dusky niche]

can I show you the code?

[knotty sun]

no need, let me show you what I think you meant but did not write

if (
(player.GetCurrentAnimatorStateInfo(0).normalizedTime >= 1 && player.GetCurrentAnimatorStateInfo(0).IsName("WeaponSwitchDown")
 || 
{M4.GetCurrentAnimatorStateInfo(0).normalizedTime >= 1 && M4.GetCurrentAnimatorStateInfo(0).IsName("WeaponSwitchDown")))

also checking for >= 1 is not a good idea > 0.99f would be better

[dusky niche]

there's a '{'

[knotty sun]

so what?

the important thing is you need to encapsulate the ands outside of the or

[heady iris]

Making it work for a completely arbitrary mesh is going to be a lot more work than just deforming things onto a sphere.

[heady iris]

You'd have to be able to project points on the original mesh onto the surface of the target mesh.

[jagged snow]

If I'm only retrieving a single value based off another value is it always better to use dictionary?

    {
        switch (impactType)
        {
            case ImpactType.Physical: return _characterImpact;
            default:
                return _groundImpact;
        }
    }```

[fervent furnace]

if the range of value (one to one/many mapping) is small, using dictionary is wasting memory and increasing query time, array is better

[hard viper]

Dictionary saves time in the sense that access is O(1), mostly independent of the size of the collection. But that comes with higher overhead cost.

[fervent furnace]

array and dictionary are both hashtable or hashmap or one to one/many mapping btw

[hard viper]

isn’t array just a pointer?

they should be contiguous memory

[heady iris]

Arrays are contiguous, yes

[fervent furnace]

hash table is just a abstract data structure that describes "something" has O(1) delete/remove/add key-value pair

[heady iris]

a hash table is a specific kind of data structure

the abstract structure would be an associative array

(or a "map")

that's what I usually say

note that a dictionary is going to be easier to reason about and implement

so i'd probably just use a dictionary

A switch expression would also be reasonable (and easier to look at)

GameObject GetSpawnVfx(ImpactType impactType) => impactType switch {
  ImpactType.Physical => _characterImpact;
  ImpactType.Magical => _kablooey;
  _ => _groundImpact;
};

One annoyance: if you don't include the _ case, the compiler will complain that you don't handle all possible values

since it's perfecly legal to do ImpactType what = (ImpactType) 123456;

I turned off that warning, because adding a default case can wind up obscuring another problem

imagine I start with

public enum Stuff {
  Foo,
  Bar
}

and I write this:

stuff switch {
  Stuff.Foo => 1,
  Stuff.Bar => 2
}

I could silence the warning by adding _ => 0 or something

But if I then added a Baz value to Stuff, I could easily forget to add a case for it in that switch expression

because there's no warning: the _ case will handle it

by leaving out the _ case, I get a compiler warning if I add a new value to Stuff without updating the switch

I find that to be way more useful

[chilly surge]

Enums being just its backing type and thus no exhaustiveness is such an annoyance in C#.

[heady iris]

yeah

give me my damn algebraic datatypes already

[quaint rock]

a Dicitonary could be used for this as well

[heady iris]

C# has baby's first pattern matching

[quaint rock]

enum keys to the prefabs

[heady iris]

and you can't exhaustively reason there either!

[quaint rock]

but yeah i mostly just make the default case or _ just throw a exception

C# type system does not let me restrict this how i want, but its a programmer error so a exception is the way

[heady iris]

this is exhaustive, compiler!

[hard viper]

wdym by exhaustive

[heady iris]

there are no possible situations in which that switch statement doesn't match and return

[hard viper]

yes there are

[quaint rock]

null

[hard viper]

nvm it is internal

[quaint rock]

ah nvm that is check first

[heady iris]

ideally i'd just have null-aware code

there is no way for someone outside of my assembly to extend any of those classes, and parent isn't null

It's possible that the compiler just can't reason about the null check

[quaint rock]

but yeah would be nice if it was aware, since then as you added types it would compiler error where you need to add cases

[heady iris]

it persists with a case null

[hard viper]

yeah, but it’s hard to write a compiler error to explain “you need a default case, except when this explicit set of conditions are met”

[heady iris]

yeah, which is why i hate this warning #archived-code-general message

like..it's true, yes

[chilly surge]

I have no idea how "hard" it is, but plenty languages have it.

[hard viper]

hard to explain, not as hard to implement

[heady iris]

but silencing that warning with a default case produces a new kind of wrongness

[thick terrace]

i think it's still technically possible with various reflection black magic and/or interop with other languages to violate that check

[heady iris]

i guess you could construct new classes at runtime

i would simply not do that

[quaint rock]

to be fair saying cause reflection is a bit of a cop out

like you can break almost anything with it

[thick terrace]

most unity programmers never would, but the C# world is larger and full of sickos, so it's a language restriction 😛

[heady iris]

Some kind of middle-ground would be acceptable

[quaint rock]

thats like complaining that Rust or Go can leak memory because of unsafe

[heady iris]

where it warns you if you have a default case that covers a situation the compiler thinks is possible

so not a default case

a wtf case

[quaint rock]

i guess other cases, which you did cover with internal i know

would be types from other assemblies extending it

[heady iris]

https://learn.microsoft.com/en-us/dotnet/api/system.reflection.emit.typebuilder?view=net-8.0

Jumpscare

[thick terrace]

actually you did cover the base type so idk, even with reflection you wouldn't be able to slip one past it

[heady iris]

This is probably necessary for some truly godforsaken COM machinery

[quaint rock]

ugh COM

[heady iris]

ultimately, it's impossible to have a type system in which:

• every valid program is accepted
• every invalid program is rejected

thus the compromises are made

[quaint rock]

used to have a pile of COM+ code for syncing photoshop selections with Maya selections based on UV layout

[heady iris]

[quaint rock]

it was ugly messy stuff

was a really neat feature to have though

[heady iris]

yeah, and that demonic pact probably sounded really sweet when you signed it

[hard viper]

is there a way to make an animated tile with a physics shape, the physics shape is the same each frame, the tilemap with a composite collider, and avoid refreshing the composite collider when the animated tile animates?

[quaint rock]

its worse then you think, have you ever dealt with photoshops api?

[heady iris]

no

i can't imagine it's pleasant

the most i've done is write scripts for Illustrator

[heady iris]

I wonder if you can subclass it and override that behavior

[quaint rock]

so, because not everything is acceisable via it i needed, i had to record actions, save them to a binary blob, then tell PS to execute that over the com interface

also had a few things break since PS actions often break if you change your UI layout

PS is such a freaking mess of a program

[hard viper]

animated tiles are kind of awkard to reset to a global timer rn. there’s just a lot of little quirks

[cinder spruce]

I have a series of card all sharing the same model. ut each card has itts own set of textures.
Is there a way to have a prefab use the texture in the same folder, or do i need to open each card prefab and assign the texture to it ?

I could do it on start or awake, but this sounds like extra operations that could be done before the project is built

[hard viper]

oh animated tiles have an update physics flag. all good

[hard viper]

i would make an SO that lets you access each texture by index or something

or a monobehaviour that does the same thing, but SO will be simpler if you need it on multiple scenes

[cinder spruce]

Yes but then you assign the texture at runtime. Isntt it less performant than having a prefab with the values already ?

[heady iris]

Vaguely

But I'd think having dozens and dozens of duplicate prefab assets woulds be worse than just having one prefab that you customize.

[cinder spruce]

I'm not sure. They wont be duplicate they will be prefab variantes. They basically only save the overrides, aka the texture changed.

[heady iris]

dozens of prefab variants also sounds miserble

You should create prefab variants when you need to add new things and make changes by hand

putting a new texture on a card isn't something you need to do by hand

whats the best way to catch all keyboard inputs (primarily alphanumerical), i was using Input.inputString but that seemed to drop inputs if i pressed buttons fast, im looking at the new input system but cant find a way to query all inputs

[steady valley]

Hey, I have a quite big problem with my unity project, and would really appreciate help please.
Due to some git issues, I came back to some old versions of the project, and now I have a lot of compilation error with the project, that I have undepending of the git commit version.
I have a lot of plugins in a Standard Assets folder and I have referencing issues between Runtime and Editor scripts of 2 plugins. Also I think my unity assets were broken and had to reinstall them
Looking at the documentation (https://docs.unity3d.com/Manual/ScriptCompileOrderFolders.html), it says editor versions should always be compiled after, but all the errors I have are in editor scripts, and all the errors are about not finding the runtime class/namespace of the package.
But, I have no error in any runtime script ? Why is this appening ?

Assets\Test\ProceduralTerrainPainter\Editor\PropertyDrawers.cs(108,38): error CS0246: The type or namespace name 'Attributes' could not be found (are you missing a using directive or an assembly reference?)

I'm on unity 2023.3.0b9, didn't change version recently

Only answer I found are https://forum.unity.com/threads/assembly-csharp-editor-reference-issue.1119976/ and https://forum.unity.com/threads/assembly-references-not-working.1042312/ but I tried everything and nothing fixed it

Posting on forums is now my last options

[heady iris]

Are you using assembly definitions?

[steady valley]

I don't and doesn't really know how it works, could a package use it in my project ?

[heady iris]

asmdefs group code together into compilation units, and you have to explicitly define which assemblies can use which other assemblies

[leaden ice]

yes most packages use them

[steady valley]

Okay thanks I'll read the documentation about that. Maybe there is some missing file unreferenced by git that were helping with that

Just found that assembly definition of one plugin have null value

That's probably the issue so

[leaden ice]

silly question did you include the Packages folder in your git repository?

You should have:

• Assets
• Packages
• ProjectSettings

[steady valley]

No it isn't, isn't it regenerated on first opening ?

[leaden ice]

no

it's part of the project

and needs to be included in VCS

The Library folder is the ephemeral one

Packages contains the package manifest and any embedded packages, both of which are essential parts of the project.

[steady valley]

Oh ok thanks

It didn't fixed the none assembly definition references problem but will surely help with git thanks

Manually adding the reference fixed it, thanks a lot!!

[arctic plume]

Is it possible to get the script of a gameobject from a child of that gameobject?

[mellow sigil]

transform.parent is a reference to the parent object

[steady valley]

There is also GetComponentInParent if you're looking for a specific scripthttps://docs.unity3d.com/ScriptReference/GameObject.GetComponentInParent.html

[heady iris]

I am moving an object along a Spline. I need to give it a rotation offset. I see that I can attach float4 data to the spline and then evaluate it. The Evaluate method on SplineData requires an interpolator. https://docs.unity3d.com/Packages/com.unity.splines@0.1/api/UnityEngine.Splines.SplineData-1.html#UnityEngine_Splines_SplineData_1_Evaluate__2___0_System_Single___1_

I also see there's this handy SlerpQuaternion interpolator https://docs.unity3d.com/Packages/com.unity.splines@1.0/api/UnityEngine.Splines.Interpolators.SlerpQuaternion.html

However, this is float4 data, not Quaternion data, so the interpolator is incompatible.

Is there something I'm missing here that'd let me use SlerpQuaternion?

I suppose I can just write an interpolator that takes a float4 representation of two quaternions and does the slerp

but it seems weird for a SlerpQuaternion to exist without it being directly usable as an interpolator!

[nova moon]

Does anyone know how you would go about loading in a model that was not initially in the build of a project? I'm attempting to stream line an issue we have at work and would like to be able to create a simple exe with a free fly camera and a config file where the user can put the file name and/or location in to the config file, and then it will load the fbx from that location so that testing can easily view the model for any issues before it gets to the developers hands. I'm just not sure how to do that short of loading the model into unity and creating asset bundles which at that point, the developers might as well just review the model themselves.

[heady iris]

Loading a model file at runtime is different from loading an asset bundle at runtime, mind you

The former requires you to actually parse that model into something Unity understands

I do believe there are runtime fbx importers available.

[nova moon]

I was having a difficult time finding importers that are used to import into a built project. Everything I found looked like it was for importing into the editor.

[heady iris]

you might have an easier time using GLTF

https://docs.unity3d.com/Packages/com.unity.cloud.gltfast@5.2/manual/index.html

there's a handy package already available

[arctic plume]

Thank you so much, that's what I was looking for

[arctic plume]

Thank you so much for your help

[thick terrace]

you might be better off looking for non-unity specific solutions too, there's lots of general C# libraries for different formats: https://github.com/izrik/FbxSharp

[heady iris]

you'd still need to turn it into a Mesh though

[nova moon]

I'll look into both of these options! Thanks @heady iris and @thick terrace !

[arctic plume]

Can you not reference subchildren from a parent GameObject?

[heady iris]

You can reference whatever you want in the scene.

You can also reference whatever you want within a prefab.

[arctic plume]

But I have a Ready Player Me avatar and I can't seem to use transform.Find to get one of it's subchildren?

I even did a Debug print loop like this:

        foreach (Transform child in currentSpeaker.transform)
        {
            Debug.Log("Child: " + child);
        }

And for some reason it only prints out the DIRECT children?

[thick terrace]

that is only looping over direct children yup

Find should work though, but you have to include the full path IIRC

[knotty sun]

you need to make that recursive to find grandchildren etc

[arctic plume]

Would the full path include the root parent gameobject?

[arctic plume]

Ahh that makes sense, I don't know how I didn't realise that 🤦

[thick terrace]

i don't think so, just every child beneath the transform you're searching in, so if it's a grandchild it'd be like Find("Child/GrandChild")

[arctic plume]

Ok I'll try that, thank you

That did the trick, thank you very much!

[warm kraken]

how do i change this default collider shape which comes with the sprite? this is and image component.

[leaden ice]

Image components should not have Colliders at all, since they're UI

As for the sprite physics shape that's in the sprite editor

[warm kraken]

Yep. The default sprite physics shape is a quad. I changed it in sprite editor and it still shows and reacts as a quad. Am i missing anything?

[warm kraken]

Im using "OnPointerEnter" which doesnt need any colliders to detect the image when mouse is over it. But the default image collider(or whatever it is) shape is quad as you can see in my previous message. How can i change that shape to whatever shape i want?

here's the object and its components (sorry for spamming)

[knotty sun]

you probably want
https://docs.unity3d.com/2018.3/Documentation/ScriptReference/UI.Image-alphaHitTestMinimumThreshold.html

[golden glade]

Is it not possible to make a method show?
The class itself is partial, I've tried moving it into the original file and out of the generated partial class, no luck.

The method itself is

[Serializable]
public enum SoundType
{
    EMOTE_JOSHUA_MAN_PAIN_HURT_GRUNT_BIG_03 = 0,
    FAIL_3A                                 = 1,
    SUCCESS_2A                              = 2,
    SW001_8BITGAMES017_EXPLOSION            = 3,
    CLICK_03                                = 4,
}

public partial class SoundManager : MonoBehaviour
{
    /// <summary>
    /// Play a sound by type
    /// </summary>
    /// <param name="type">Type of sound</param>
    public void Play(SoundType type)
    {
        _instance.Play((int)type);
    }
}

And SoundType is auto-generated but I will post that too.

I've tried restarting Unity too but no luck either

does Unity inspector not like partial classes?

Works if the argument type is an int but not an enum.

According to a post they say it should work, you only need the serializable attribute, which I have.
https://discussions.unity.com/t/enum-as-a-function-param-in-a-button-onclick/214010/5

[knotty sun]

yep, events don't work with enums

[thick terrace]

iirc that's because of the way it's serialized under the hood

[golden glade]

Weird, because on the forum they show exactly that.

Do you know any other way of making it work? Like a custom drawer?

[thick terrace]

what they're showing there doesn't match what you're trying to do, theirs is just a public field

[golden glade]

Oh, now that I saw it zoomed in, yup. You are right.

[thick terrace]

i think what they're actually suggesting is make a new MonoBehaviour with that property on it, and use that as the argument to your method

since any UnityEngine.Object should be ok as a parameter

[golden glade]

Ouch.

Thought I could make this system zero-code or additional components .. Maybe not.

[thick terrace]

i think the other way around it would be a separate script with a different type of UnityEvent with the correct type parameter, but it's an additional script either way

[golden glade]

Yeah 🤔

[static matrix]

how can I get which clip an animator is playing?

[golden glade]

Dream's dead I guess unless I somehow magically create a custom event class and an inspector for it

[rigid island]

GetStateInfo or sum

[static matrix]

alright

[rigid island]

https://docs.unity3d.com/ScriptReference/Animator.GetCurrentAnimatorStateInfo.html

[golden glade]

What are you trying to achieve?

[static matrix]

and I presume the base layer is 0 correct?

[golden glade]

Most likely it is in what order these are

[rigid island]

if your layer is 0

[golden glade]

if you do not have any extra layers then yes, 0 is correct.

[vale bridge]

Is there a way to get a component whose upper class is for example "Weapon"?

For reference I'm triyng to pull attributes like damage and trigger the weapon behaviors via an Aim script that knows nothing but the base class methods. For example if I got the reference I would call "obj.Fire()" where every class inheriting Weapon would have to implement that method; I just need the specific script that inherits this on a child object

[heady iris]

You can use a parent type with GetComponent, yes.

You can also serialize a reference to a parent type.

[vale bridge]

Ooh so if I do getComponent<Monobehaviour>() it'll return all the components?

Is that how it works?

[heady iris]

All of the components you've made, at least

[leaden ice]

All the monoBehaviours

[heady iris]

GetComponent<Behaviour>() or GetComponent<Component>() would be even more broad

[vale bridge]

nice

[heady iris]

Behaviour covers many built-in components that can be enabled and disabled

[leaden ice]

Also note GetComponent vs GetComponents

[vale bridge]

I did not know there was a difference

[heady iris]

but there are some other kinds of components too

Renderers, notably

[vale bridge]

I imagine the latter returns an array or something

[vale bridge]

[heady iris]

I just noticed that Unity is producing a warning whilst burst-compiling some code

[BurstCompile]
static class NoiseMethods
{
    [BurstCompile]
    public static float Noise(float t, in float2 vec, in float2 offset)
    {
        return noise.snoise(vec * t + offset);
    }
}

The warning states that compilation was requested for this, but that it's not a known Burst entry-point

The Burst inspector shows native code compiled from this method, so it seems like it's still working..?

I can't get it to re-appear after modifying my code now. I'm not sure exactly when it shows the warning

[static matrix]

tf is a burst

[leaden ice]

https://docs.unity3d.com/Packages/com.unity.burst@1.8/manual/index.html

basically the special compiler for DOTS

[static matrix]

tf is a dots

[leaden ice]

https://unity.com/dots

[heady iris]

Burst allows you to compile C# to native code ahead of time

[signal moon]

Hi, im using a code found online, about good hand positioning in card game. It seems like i set everything like original autor did yet i have few problems, mainly with cards trying to leave the canvas but being blocked, and a script not reading position (those 2 are related). I have following errors: NullReferenceException: Object reference not set to an instance of an object CardWrapper.SetAnchor (UnityEngine.Vector2 min, UnityEngine.Vector2 max) (at Assets/Scripts/Cards/Card Aligment/CardWrapper.cs:106) CardContainer.SetCardsAnchor () (at Assets/Scripts/Cards/Card Aligment/CardContainer.cs:207) CardContainer.InitCards () (at Assets/Scripts/Cards/Card Aligment/CardContainer.cs:54) CardContainer.Start () (at Assets/Scripts/Cards/Card Aligment/CardContainer.cs:49)

[heady iris]

It only works with a limited subset of C#

"Bursted" code is completely unmanaged.

You aren't running stuff in the managed C# runtime

[signal moon]

with code

[heady iris]

in this case, I discovered that it was way faster to run this Mathematics noise method when it's burst-compiled

[signal moon]

problem is it seems like i did assign everything where needed

[heady iris]

well, the C# runtime doesn't throw random exceptions for fun. Have you used Debug.Log to make sure you don't have any null references at the site of the error?

[signal moon]

Well, if i get those messages it must be null, i just can't get it why bcs i have autors project opened in next tab

[heady iris]

Okay, but have you done any debugging?

[heady iris]

log all of the variables you're trying to use on those lines

[signal moon]

there is only 1 line in Awake method private void Awake() { rectTransform = GetComponent<RectTransform>(); } yet every object has rect transform.

[clear oriole]

I did eventually figure it out, its in the camera Data is where you have to set it

[lean sail]

This is what you are assuming, do actual debug and prove to yourself what is null. Also I cant even see which code it refers to on mobile, you should paste using one of the code sites

It looks like a different method entirely is throwing a null error by the stack trace
