isnt that line is the like anchor

for the limit

didnt think this would matter

[still jungle]

spent my time in paint to let you visualize what you did wrong, and it aligns with the behaviour in video you provided

in video you provided the lever is initialy over the upper angle limit so you can drag it with low force to open position

you can do it because its not hold by the limits

but when it goes back to start position ( the red line) then its back in bounds of angle limits

so you cant move it over the angle limit without big force

[stark sun]

so it should be like that?

when ı first tried it was like this but I could move it

I am sending you a new video

[still jungle]

now it have good angle limits, but you breaking those limits anyway with high force

[stark sun]

but it just looks like just the point where joint takes as starting point is not correct.Because if I broke the joint I could be able to move it freely dont I?

[still jungle]

why you would want it to break the limits? it should stay in the limits, and the joint start point looks now correct according to the open state angle of trapdoors

next time you should provide scene view which show behaviour of the lever and angle limits, with inspector open at the lever, so it would be much less of guess game

just modding a game, how do i stop this from happening

ignore PhysicalBehaviour

[bleak plank]

Hello, I’m an XR game dev who mainly just focuses on making vr games, but I wanted to try a PC project again, I haven’t made a PC project in two years, and I really wanted to try it again. I made this prototype in hdrp, although there are some things i need to fix and need help with.

1. When I move my mouse, you can see the UI has some motion blur, I don’t know why that is

2. Animations are snappy, they aren’t smooth as desired, i’m using all mixamo animations. I don’t make PC projects so I kinda have no clue how to fix these issues

[leaden ice]

Neither of these seem like code issues.

Undo.RecordObjects(objects,  "Destroy missing scripts");

foreach (GameObject target_object in objects)
{
      Component[] componentsAttached = target_object.GetComponents<Component>();
      
      foreach (Component component in componentsAttached)
      {
          if(component ==  null ||  component.GetType() ==  null) {
              DestroyImmediate(component);
              compsRemoved ++ ;
          }
      }
}

I am trying to destroy missing script references on objects in a scene, but it does not do anything, finds the missing scripts correctly, but they are not destroyed.

[thin aurora]

Does it enter the if-statement?

Or does it at least increment compsRemoved here?

[potent sphinx]

Yeah it does increment that counter

It is confidently logging out "Destroyed 221 Missing Scripts 😎 "

[hexed pecan]

Are you targeting prefabs or scene objects or both?

[potent sphinx]

Scene objects only..

[hexed pecan]

What if you mark them dirty with EditorUtility.SetDirty afterwards

[potent sphinx]

I am now trying to deserialise the object and then remove componets mnaully

[potent sphinx]

It helps with saving changes, but I am unable to make any changes for them to be saved

[hexed pecan]

Yeah I think it's because you are passing null into DestroyImmediate so it doesn't know what to destroy

[potent sphinx]

Well then remove the null flag in if-statement and directly pass the componet if Type is null ?? this is confusing, because unity leaves the component on objects if the component used to carry a script, so component itself is not actually null....

[hexed pecan]

@potent sphinx Wait.. since when was this a thing
https://docs.unity3d.com/2019.1/Documentation/ScriptReference/GameObjectUtility.RemoveMonoBehavioursWithMissingScript.html

[potent sphinx]

Jeez

[hexed pecan]

Apparently it's been around forever, never heard about it lol

Just saw it mentioned in a discussions thread

[potent sphinx]

And it worked

😭

Thank you so much

I had been looking at unity forum posts from 2010

[stark sun]

limits were correct I think.Its about my grab script.Because I cant get the lever to right side this way

[still jungle]

maybe, its more like of a guess game with provided informations

[stark sun]

can you take a look at my grab script. I cant see a problem but maybe you can see. Because problem occurs when I grab.

[still jungle]

i can check it later but record how you interact with the lever with scene view focused on the lever, and inspector have to show the HingeJoint2D component during interactions

[lost rivet]

is there a way to copy a component to another object?

[hexed pecan]

At runtime?

[plucky inlet]

Reflection I guess

[lost rivet]

yeah

[leaden solstice]

What for

[hexed pecan]

Again, JsonUtility can do that

[lost rivet]

i mean, i suppose you could serialize and deserialize it

[hexed pecan]

You'd just need to AddComponent first

[lost rivet]

yeah i just thought of that xD, but i was wondering if there was a more direct way

[plucky inlet]

Direct way (reflection), performant way (json)

[leaden solstice]

Serializing then deserializing is pretty much direct way

[lost rivet]

how would you do it with reflection anyways?

[plucky inlet]

you get the fields for that component (class) and then get values from your source and set the fields in your target

[leaden solstice]

Don’t do that tho

[lost rivet]

ohh makes sense

but i think serialization might be better

[leaden solstice]

You don’t know what fields Unity use internally

And what is going to happen when you blindly copy them

[lost rivet]

well i am going to use it for my own scripts for the most part

[leaden solstice]

Serializing is more robust way since you can control what is serialized

[lost rivet]

also, i dont think they json utility thing works on built in components

[hexed pecan]

Yeah but if you just copy all of the data then it might break things

[leaden solstice]

JsonUtility is same serialization as you save to prefab or scene

[plucky inlet]

Both have their pros and cons. If you use some unserializable properties for example or what not. And same goes for copying field values with reflection. As long as you know, what you do, you will work your way around one or the other, and I suggest the json way too.

[lost rivet]

it throws an error when i try to serialize an engine component

let me show

[plucky inlet]

There we go already 😄

[hexed pecan]

The doc only mentions MonoBehaviour/ScriptableObject support yeah

Nothing about builtin components (This doc i mean https://docs.unity3d.com/2020.1/Documentation/Manual/JSONSerialization.html)

[plucky inlet]

Newtonsoft might be more useful in any case too

[lost rivet]

newtonsoft doesnt work either

[plucky inlet]

can you show, what you are trying to serialise?

[lost rivet]

i tried, it cant serialize either because the monobehavior has the gameObject property

which causes an endless loop

[leaden solstice]

Don’t use newtonsoft for this

[plucky inlet]

so you not gonna show your class you want to serialise? 😄

[lost rivet]

i already said engine components, could be anything

for example linerender i guess?

[leaden solstice]

In any case, it’s just better to find a way that works with either Instantiate or manual logic

[stark sun]

okay it was about grab script.It sets limits for the joint I create on my hand to grab things.I set use limits to false and everything works now.

[lost rivet]

most of my custom scripts work fine tho

[leaden solstice]

For your question mark Newtonsoft is not suitable for unity object serialization

[cold parrot]

you may want to use something like this in addition to newtonsoft to fix the "unity" problems. However you still can't use it to instantiate monobehaviours https://openupm.com/packages/jillejr.newtonsoft.json-for-unity.converters/

[plucky inlet]

"object", thats like everything. Do you have an example?

[hexed pecan]

UnityEngine.Object

[leaden solstice]

“Unity object”. UnityEngine.Object

[lost rivet]

yes ive already done this, doesnt help

[stark sun]

create that component in runtime (in script) then assign the values from other script by referencing.

[lost rivet]

anyway this is like a seperate problem entirely

i will figuere it out

[cold parrot]

you can use newtonsofts .Populate() API to write a serialized state to an existing instance

[plucky inlet]

I guess, you have to write your own custom classes for the builtin ones then, that just hold the values for the builtin ones so you can serialise and deserialise them

[cold parrot]

its a good idea to use a memento pattern when serializing monobehaviours

[lost rivet]

as i said newtonsoft cant serialize components because of circular dependencies, even with converters

[cold parrot]

sure it can, you just have to do it right

[leaden solstice]

It’s probably the references your class is holding

[cold parrot]

also you should not serialize references anyway, that causes more problems than it solves

[leaden solstice]

Anyhow can’t you just Instantiate the whole game object

That’s easist way out

[cold parrot]

its a fundamental feature of any save-system that you come up with a maintainable way for referencing stuff in savegames

[lost rivet]

I was having the same discussion yesterday hehe
no because the object can mutate at runtime

[leaden solstice]

What do you mean

[lost rivet]

after instantiated from prefab

[leaden solstice]

You can instantiate that instance

Instead of prefab

[lost rivet]

wym o;o

[leaden solstice]

Or use it as prefab, ig

Instantiate is essentially copying the game object you pass in

[lost rivet]

oh yeah right, i think we have mixed a couple different problems here

anyway, ill figuere out

thanks all

[thin aurora]

That's an issue with Unity, not Newtonsoft. Considering there are packages available to fix a lot of these issues I assume one also exists for this

[leaden solstice]

It’s issue of neither. It’s simply not the right tool for the job.

JsonUtility shouldn’t be looked as json serializer competing with Newtonsoft, it should be looked as Unity serializer

[latent latch]

The way I do component serialization is just making a load manager and create lookup tables to bind IDs to components

and JsonUtility works just fine

then create a whole GO from it

[leaden solstice]

It works when you don’t really care about result being Json

Whatever specifically Json is required Newtonsoft should be used, JsonUtility is just utility happened to choose format as Json

[thin aurora]

Are you saying that JsonUtility is able to deserialize into MonoBehaviour classes whereas Newtonsoft can't do it?

[leaden solstice]

I’m saying that JsonUtility is there as a serialization utility that follows Unity rule, such as SerializeField. And not as universal Json serializer.

It’s not important that format is Json, it would do the same if format is XML

And it’s sane to use it for serializing what Unity saves

[thin aurora]

That's not what I asked, and even then this is configurable. Even easier if you use [JsonIgnore]

I don't see what benefit JsonUtility has over Newtonsoft in any way. Pretty sure even Newtonsoft can have support for fields

[latent latch]

It's very limited compared to when you can serialize at editor time, not everything usually you can [SerializeField] work with JsonUtility I noticed

[thin aurora]

Not that I think you should switch, I just don't see why we would praise a clearly outdated and worse serializer

Especially when most (all?) of the quirks against Newtonsoft come from the bad conventions that Unity has made

The only reason why JsonUtility even works here is because it also uses the outdated BinarySerializer that Unity itself uses

Which, by the way, is very likely to be gone when they switch to CoreCLR since it's been removed from .NET due to it being really, really bad
(Source)

[latent latch]

NewtonSoft does actually do magic compared to Unity's but that usually comes at a cost a larger amount of data serialization. Ultimately getting everything down to IDs would be the way if you're constructing whole GOs

[leaden solstice]

Newtonsoft doesn’t know Unity serialization rule by itself, and you’d have to provide custom serialization config to handle Unity object which just duplicated logic

Use Newtonsoft for when you actually need Json. It’s not praising JsonUtility at all lol

[lost rivet]

what does that even mean

[thin aurora]

I'd love to see an example where JsonUtility is actually a better choice compared to Newtonsoft

[lost rivet]

personally, because its not compatible with unity

which is a unity problem, i agree

[leaden solstice]

? What field would use binary formatter

[thin aurora]

It's compatible with Unity, there's even a specific package available for it

[leaden solstice]

I’ve been saying they are not competing, and you were clearly not reading

[thin aurora]

Unity and JsonUtility use the BinaryFormatter. That's why you always have to plaster everything with [Serializable]

[lost rivet]

for example you cant serialize monobehaviors directly

even with the package

[thin aurora]

You're not supposed to do that anyway

[leaden solstice]

Serializable is just flag attribute and if you see the content that is not binary formatted

[hexed pecan]

What if you want to copy a component's data onto another

[lost rivet]

why not, its just code

[thin aurora]

And even if you want to do that, you should use the actual Unity API and instantiate it. There's a PopulateObject method for setting data

[hexed pecan]

How do you instantiate a single component

Without cloning the whole gameobject

[thin aurora]

It's clear that you guys rely way too much on this if you think it should be able to do all this

[lost rivet]

i am saying you cant even serialize the component to begin with, how are you populating it

[thin aurora]

It's a serializer, not a full on object creator

[stark sun]

how can I make this object to look up like this at start?

[hexed pecan]

So why not use JsonUtility where it does the job better and simpler?

You are just getting super defensive about newtonsoft for no reason.

[latent latch]

JsonUtility doesnt serialize components, no?

[hexed pecan]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/JsonUtility.FromJsonOverwrite.html

It works with MB and SO

[lost rivet]

not engine components, but it can your monobehaviors

[hexed pecan]

But not with builtin components AFAIK

[plucky inlet]

For my last project, I just build equivalents to builtin components, like a serializablevector3 for example and what not

[lost rivet]

but what happens if you try to serialize an object reference?

[lost rivet]

vector3 is not a component...

alsoit should be serializble by default

[steady bobcat]

giving json to you guys was a mistake 😆

[thin aurora]

You also seem to conveniently forget that JsonUtility is unable to deserialize a lot of common types, which is the main reason why you would not use it

[leaden solstice]

It becomes as Unity serializes it

Probably object ID

[hexed pecan]

UnityEngine.Object or just object in general?

[latent latch]

Ideally you shouldnt be trying to serialize stuff at a reference level. Grab data then point to some identifier so next time you recreate it you can do it at runtime

[lost rivet]

but who is json? 🤔

[hexed pecan]

I'd imagine the behaviour is the same as copy/pasting a component in the editor

[plucky inlet]

was more of an example of how you can adapt your objects to something useful and reassign them. But you right, vector3 per say was not related to the component specifically

[leaden solstice]

Yes

That’s the whole point

You don’t care about content as long as it contains data that Unity serializes, and it’s weird to go through the hoop just to use Newtonsoft with it

[hexed pecan]

I'm not denying that, but it's also not the point of this discussion. You can always use a serializable dictionary (for example) to get around that

[thin aurora]

Which is not going through hoops with an alternative to get things working?

[hexed pecan]

Not a massive hoop IMO

[thin aurora]

Let's not forget nullable types here. JsonUtility can't use those either

Seems like quite a hoop to me

[hexed pecan]

I like how things align with unity's own serialization

Because that's literally what it is

[leaden solstice]

You don’t need that if you want to follow Unity serialization

[plucky inlet]

Feels like this discussion ran out of sight from the actual question, didn't it? 😄

[hexed pecan]

Json is always a hot topic :p

[warm badger]

what features do you think should be considered when registering a swipe gesture?

[thin aurora]

The real issue here is Unity like always

[plucky inlet]

yeh not taking myself out of here being a driving force, too. It just started to be like a subjective opinion fight rather then sticking to the topic now 😄

[plucky inlet]

not sure, what you mean with that question

[latent latch]

i'd just go learn some networking and learn how to do serialization proper, so when you f up you pay the cost in bandwidth

[hexed pecan]

It is certainly subjective and usecase dependent

Saying that X is always better than Y is naive

[leaden solstice]

Whatever is not supported in Editor, like Dictionary, is not necessary for JsonUtility

[plucky inlet]

udp and messagepack ftw 😉

[leaden solstice]

Because it’s not JsonUtility to support whatever Unity doesn’t support

[hexed pecan]

Wdym with features? Like methods to use to detect swipes?
Have you read this?
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Touch.html

[lost rivet]

again, what does that even mean

Unity does support dictionary

[plucky inlet]

you guys wanna throw that discussion in a thread probably?

[thin aurora]

I don't understand this take. Are you saying you never use dictionaries or nullable types because JsonUtility doesn't support it?

[leaden solstice]

Unity doesn’t support Dictionary serialization

[thin aurora]

How to you handle distinct key-value pairing then?

I'm so confused

[lost rivet]

well yeah but thats begging the question isnt it?

[steady bobcat]

whats a thread? /s

If you want to serialize data properly use something like protobuf or bebop (not sure if its supported in unity but still)

[latent latch]

if everything isn't a struct with value types you're doing it wrong and that's what I've concluded after fighting with Unity for years

[warm badger]

i mean, i am not sure about that...but what is making me confused is, should swipe be considered when a finger(touch) is lifted from screen aafter a fast movement? or it can stay stil on the screen after a fast movement?

[lost rivet]

true

[leaden solstice]

Gosh, if you need Json, use Newtonsoft. If you want what Unity serializes, use JsonUtility. Is it hard to understand?

[lost rivet]

yes because it doesnt make sense

[thin aurora]

This has nothing to do with that

[leaden solstice]

What doesn’t

[steady bobcat]

i've done swipe detection before and its usually detecting some velocity between inputs within some time. id say its up to you if you want it to require a pointer exit/up.

[plucky inlet]

That is totally up to your gameplay tbh. So as always, depends on what you wanna achieve

[steady bobcat]

my guy wants the easy way out to json serialize a whole scene

[thin aurora]

Why not just serialize the whole game while we're at it

Who needs a binary executable

[latent latch]

I've a load manager specifically for each type of object I serialize

[plucky inlet]

I want a "let it go" frozen emote so bad right now 😄

[thin aurora]

Sorry, I'm just having fun at this point

[hexed pecan]

At least it's somewhat unity related

[lost rivet]

how does your load manager work btw because now i am curious

sry to bother lol

like do you serialize the prefabs id and then go the manager to get the og prefab?

[latent latch]

If we're talking the bare minimum amount of data needed to serialize an object it's simply an ID which you can create a lookup table for, so when you load up your game, pass that serialized identifier into it and point to the required loading process

Along with what ever other value types you bundled with that ID

Now, to make things even more simpler, if the object you're constructing was previous part of a prefab, you've now some blueprint to build upon

[steady bobcat]

For a game I work on with 1000+ objects each has a configuration entry with a unique string id. Each has an address for its prefab which is used to load it back another time.

[lost rivet]

so i want to load in eggs, i pass an egg identifier, which goes to the eggloader?

[hexed pecan]

Eggsactly

Sorry i'll go now

[latent latch]

lol, yeah. You can also use interfaces like an ILoadable to implement on each type of object that can be serialized

IWritable, ect

[azure frost]

Okay, I'm getting closer to finishing my game's control-scheme with the help of my bro...

But I've got quite a few steps left to go...

I wonder what I should tackle first...

[heady iris]

step 1: save all of the process's memory to a file

[split junco]

I tried development build but the error is still there.

This is from the debug stack

I don't get these errors when I use Quest Link and hit play on Unity. I only get this when I am exporting APK to Quest.

[plucky inlet]

What does your ServerLoadManager do on Start?

[plucky inlet]

can you show that method. I guess, your quest cant connect to something your editor can but you still try to access it. Logging might help

[calm echo]

alot of this effiecient loading and saving is similar to networking data transfers.
If you care about size and efficiency when doing these tasks, you can approach it from a similar perspective

[split junco]

Thanks! I am loggging errors. Here's ServerLoadManager script.

public class ServerLoadManager : MonoBehaviour
{
    public float currentLoad { get; private set; } // Current server load percentage
    public float NormalLoadThreshold = 50f;  // Below this is considered Normal load
    public float HighLoadThreshold = 80f;    // Above this is High load
    public float OverloadThreshold = 95f;    // Above this is Overload
    public bool isServerOnFire = false;
    public string serverStateString { get; private set; }
    public ServerLoadState currentState;
    private ServerLoadVisualizer serverLoadVisualizer;
    public Color serverResponseDataPacketColor { get; private set; }

    // States
    public NormalLoadState normalLoadState = new NormalLoadState();
    public HighLoadState highLoadState = new HighLoadState();
    public OverloadState overloadState = new OverloadState();
    public ServerDownState serverDownState = new ServerDownState();

    public UnityEvent onServerStateChanged;
    public float ipDistributionSliderValue, trafficVolumeSliderValue, requestFrequencySliderValue;
    public float ipDistributionWeight, trafficVolumeWeight, requestFrequencyWeight, overallConstant, maxPossibleLoad;
    public DataPacket dataPacket;
    private ServerLoadState lastState; // Store the last state
    public ServerSO serverData;
    private float variationRate = 2f;
    private float fluctuationInterval = 1f;
    private float targetLoad;
    private float fluctuationValue;
    public static ServerLoadManager Instance;

    private bool serverShutdown = false;
    private void Awake()
    {
        if (Instance == null)
        {
            Instance = this;
        }
    }
    
    

void Start()
    {
        serverResponseDataPacketColor = Color.green;
        if (onServerStateChanged == null) onServerStateChanged = new UnityEvent();

        ipDistributionSliderValue = IPDistributionPanel.Instance.ipDistributionSlider.value;
        trafficVolumeSliderValue = TrafficVolumePanel.Instance.trafficVolumeSlider.value;
        requestFrequencySliderValue = RequestFrequencyPanel.Instance.requestFrequencySlider.value;

        IPDistributionPanel.Instance.ipDistributionSlider.onValueChanged.AddListener(OnIPDistributionSliderValueChanged);
        TrafficVolumePanel.Instance.trafficVolumeSlider.onValueChanged.AddListener(OnTrafficVolumeSliderValueChanged);
        RequestFrequencyPanel.Instance.requestFrequencySlider.onValueChanged.AddListener(OnRequestFrequencySliderValueChanged);

        serverLoadVisualizer = GetComponentInChildren<ServerLoadVisualizer>();
        if (serverLoadVisualizer == null) Debug.LogError("ServerLoadVisualizer not found");

        dataPacket = FindObjectOfType<DataPacket>();
        Debug.Log($"Datapacket before calculate server load: {dataPacket.currentState.DataPacketStateName}");
        CalculateServerLoad();

        if (currentLoad <= NormalLoadThreshold)
        {
            SetState(normalLoadState);
        }
        else if (currentLoad > NormalLoadThreshold && currentLoad <= HighLoadThreshold)
        {
            SetState(highLoadState);
        }
        else if (currentLoad > OverloadThreshold)
        {
            SetState(overloadState);
        }

        InvokeRepeating(nameof(CalculateServerLoad), 0.3f, 1f);
        StartCoroutine(DelayedFluctuationStart());
    }

Basically, serverload manager is a state machine.

Again, this all is working fine via quest-link. But not when I export it to APK (i.e., build and run option).

[plucky inlet]

Like two debug.log on your entire start() is not logging tbh. you never check your dataPacket for example. just access its values

[plucky inlet]

Id say, get some logging in to check if everything as expected, then maybe comeback here if you didnt find out yet. and next time pls !code

hello

[rigid island]

https://nohello.net

[split junco]

Thanks. I'll do that. I want to know why this works fine in Unity but not when I build an APK.

[fiery stratus]

random side-note, consider using a "singleton monobehaviour" base, makes things super easy like https://gist.github.com/ErikOG/dbc8d831bb22531cb870c57e098a1172, I use this pattern every time I'm prototyping, over time it's a pretty solid time save ^^ (the lazy loading is nice too, don't have to interject into awake or start)

[split junco]

Okay I did this and the error is when I'm trying to find ServerLoadVisualizer in children.

So this works in the Unity but for some reason when I'm building in the apk it's failing.

Debug.Log("Server Load Manager Start6");
        TrafficVolumePanel.Instance.trafficVolumeSlider.onValueChanged.AddListener(OnTrafficVolumeSliderValueChanged);
        Debug.Log("Server Load Manager Start7");
        RequestFrequencyPanel.Instance.requestFrequencySlider.onValueChanged.AddListener(OnRequestFrequencySliderValueChanged);
        Debug.Log("Server Load Manager Start8");
        serverLoadVisualizer = GetComponentInChildren<ServerLoadVisualizer>();
        Debug.Log("Server Load Manager Start9");
        if (serverLoadVisualizer == null) Debug.LogError("ServerLoadVisualizer not found");

        dataPacket = FindObjectOfType<DataPacket>();
        Debug.Log($"Datapacket before calculate server load: {dataPacket.currentState.DataPacketStateName}");

[steady bobcat]

A few things to check. Is get component allowed to get from inactive objects? Is this an addressable scene?

[split junco]

Scratch that. The error is down below. It's sort of the same one. I don't know why this is an error. What am I missing. This works fine in Unity. Not when I am building apk. I just can't wrap my head around this. If this was a problem, wouldn't this also show up in Unity?

if (serverLoadVisualizer == null) Debug.Log("ServerLoadVisualizer not found");
        Debug.Log("Server Load Manager Start10");
        dataPacket = FindObjectOfType<DataPacket>(); //Error Here
        if(dataPacket == null) Debug.Log("DataPacket not found");
        if(dataPacket != null) Debug.Log($"DataPacket found");
        Debug.Log($"Datapacket before calculate server load: {dataPacket.currentState.DataPacketStateName}");
        CalculateServerLoad();

[autumn hull]

Thank you kind sir

[split junco]

Okay. I fixed the issue. I wasn't able to access properties of dataPacket. They were initialized in the Start and I moved them to Awake. This worked. I'm still not sure why it worked on Desktop but not after building APK. Should I raise a bug request on Unity? I just want some explanation of what's happening so that I don't run into issues like this.

[vital salmon]

any advice how to figure out how someone's game crashes? There's a specific player who's game is crashing. Looked through the code and I load things with addressables. But it's very light stuff (a main menu). How can I help this player? He aint tech savvy, any advices?

[split junco]

The best way would be to look at the logs. If it's an android game, use Android LogCat. If it's a PC game...there will be an application that generates logs.

[plucky inlet]

Always be in control of what oyu loading and what to expect from other classes. Dont just trust in asyncs running inthe same order as in editor or other stuff in parallel 🙂

[vital salmon]

pc game hmmm

[split junco]

https://discussions.unity.com/t/solved-where-to-find-logs-of-a-built-game/905290/2

[heady iris]

The order of execution for things like Start and Update (amongst types with the same script execution order value) is completely arbitrary. You get whatever order Unity decided to store the objects in.

If your game depends on a specific order, you must enforce it

[steady bobcat]

You can use unity cloud or firebase or sentry or bugsnag to have crash reports be uploaded, could be worth doing if you have many users.

[heady iris]

I wonder if you could scramble the order of objects to help detect that kind of issue

[vital salmon]

thank you! Just tried installing cloud diagnostics, seeing how that works

[steady bobcat]

Should work decently. You should check the docs for the platform for how you upload symbols (needed for crash stack decoding)

[vital salmon]

symbols?

[heady iris]

the names of functions and whatnot

the built game does not inlcude this information

well, more notably, the symbols give you line numbers

I've been having problems getting symbols to upload, so I just see weird gibberish in my stack traces. I do still get function names.

[steady bobcat]

I don't think you can get line numbers for il2cpp ever cus I've not seen it work.
But symbols are needed for crashes as otherwise the stack is unreadable.

[vital salmon]

ah okay ill have to figure out how to get em

[steady bobcat]

Symbols are output with a build so just upload em, the docs should explain where

If using mono it may not I forget

[vital salmon]

I use il2cpp

ill chekc it out, thanks!

[plush mulch]

Can someone tell me where in game dev would I need to use dsa intensively?

[still ermine]

You mean like competitive programming stuff?

[plush mulch]

I need to make a project related to data structure and algorithm and I was wondering if I could make a game that uses dsa alot like the sokoban(box moving game)

Basically asking for recomendation of games that uses concept of linkedlist, list, queue, stack, tree, graph, hashing alot

[cold parrot]

You can shoehorn these into any project, except linked list, that’s a mostly useless datastructure in games, but you can obviously use it if you want to make bad choices.

[plush mulch]

But what type of game would it be most suitable in, tower defense? 🤔

[cold parrot]

Any game

it really doesn’t matter, you use all of them in practically all games

[plush mulch]

Alright I'll just pick one and look into it then

[cold parrot]

do anything with physics or pathfinding —> tree & graph, you can’t make a game without lists. Any lookup is a hash map or hash set.

[plush mulch]

Okayy thankyou

[cold parrot]

Any list is also a stack, queue is useful for message/command/action ordering

[plush mulch]

Got it, thankyou for your help

[split junco]

How does one enforce it?

[heady iris]

you can have one object call a "setup" method on a second object, rather than using Awake or Start on both of them

[split junco]

Something like this?

public class GameManager : MonoBehaviour
{
    public string GameSettings { get; private set; }

    private void Awake()
    {
        GameSettings = "Hard Mode";

        // Find and set up PlayerController
        PlayerController player = FindObjectOfType<PlayerController>();
        player.Setup(this);
    }
}

public class PlayerController : MonoBehaviour
{
    private GameManager gameManager;

    public void Setup(GameManager manager)
    {
        gameManager = manager;
        Debug.Log("Game settings: " + gameManager.GameSettings);
    }

    private void Start()
    {
        // Setup ensures this data is ready by the time Start is called.
    }
}

[fallow quartz]

If I create an animation for an object how can I do so the anim just changes his position and rotation based on the own object

and not the global coordinates?

Because when the game starts all the objects with that anim go to the same spot

[leaden ice]

best practice is to have the animator on a parent object

and the thing being animated on a child object

Animator always animates local positions, but if your object has no parent, a local position is world position

[fallow quartz]

okay, and then if i want to use the same animation for 3 different objects but when the game starts I want them to be at different positions so they are not moving at the same pace (To make it kinda dynamic) what can I do

[leaden ice]

do what I said

And it will work

[kind nymph]

i remember being able to do this before and now I've forgotten how to do it even though it seems so simple in theory.
basically, I've been trying to get a system that cycles through a List<T>, the intended behaviour is if you try to cycle beyond the list you just get sent back to the start again and vice versa if you cycle beyond the start.
I seriously have no idea why this is isnt working because it's not even throwing any errors or anything but nothing is happening, so it could be a case of it breaking instantly but yeah I have no idea (if this made no sense i can try to explain better but i dont want to write a 1500 word essay in a single message, also yes I am using new input system with invoke unity events)

Below is a link to the cycling function and attached is an image of the list in the inspector

https://paste.mod.gg/mmbknjcyfzjd

[leaden ice]

The code doesn't really make sense to me

why is there a for loop here at all?

[kind nymph]

i think the way i planned for it to work is

1. loop through the list until the current projectile name matches the index's projectile name
2. get the new projectile from the list based on the input of the 1D Axis action (aka, if -1 then get the previous element in the list, otherwise get the next)

but in reality it didn't really work at all, i had an older version that was able to go up one time and got stuck afterwards but it couldnt go back without an OutOfRangeException but i dont think I had any failsafes for that in place

[leaden ice]

there's no need to loop through anything as far as I can tell

Just something like this:
https://paste.mod.gg/bdjdfaydggrp/0

(also I'm asssuming your list is a List<Projectile>)

but I have no idea what it is so that part is just a guess

[kind nymph]

yeah its a custom class

the definition is public List<PlayerProjectile> projectiles = new List<PlayerProjectile>();

[soft nymph]

    {
        animator.SetBool("Dashing", false);
        dashing = false;
        transform.Find("FireEffect").gameObject.GetComponent<SpriteRenderer>().enabled = false;
    }

for some reason the enabled on my FireEffect component is not being changed

[simple void]

Why not use a dictionary

[leaden ice]

becasue you're not setting the enabled on your FireEffect component

you're setting it on the SpriteRenderer component

[soft nymph]

yah I mistyped

thats intentional

I want to disable the sprite renderer

[leaden ice]

Well you're using GameObject.Find so that's a red flag immediately

[soft nymph]

oh?

[leaden ice]

1. Is the code actually running? Use Debug.Log to find out

2. Any errors in console?

[soft nymph]

yes and no

[leaden ice]

How did you verify 1

[soft nymph]

I am calling another function right above it in the same block and thats running fine

[leaden ice]

That's not good enough

there's an if statement here, and who knows what other code may be doing.

use Debug.Log

make sure it's getting printed

[kind nymph]

if you mean c# dictionaries then i cant do that because every KVP in a dictionary is the same type, in my case i need multiple different types

[soft nymph]

if it didnt run, wouldnt the dashing bool of animator not be false?

[leaden ice]

Use Debug.Log

you are making assumptions

[soft nymph]

I did its running

[leaden ice]

and that's what leads to bugs

[simple void]

Why not use the string for the name? I’m not sure I understand ur problem

[leaden ice]

If the code is running and there's no errors - then it's working fine

SOmethiung else is probably disabling the renderer

or you're enabling the renderer of the wrong object

[kind nymph]

i dont have multiple projectile objects im changing the sprite of the clones i make from the original instance, so just getting the name of the sprite directly seemed to cut out the clutter

[leaden ice]

There's only one FireEffect in the whole scene?

[soft nymph]

yes, and this is the only code the accesses it

[simple void]

Also you could write
index = ((index + step) % listcount + listcount) % listcount

[leaden ice]

How do you know there's only one

[soft nymph]

because I manually create it

and there is only one

[leaden ice]

People make mistakes

Search the scene at runtime

[soft nymph]

i dont think you understand

this whole project has 6 files

[leaden ice]

I understand completely

[soft nymph]

yep, only one fire effect

what did you mean by "Find" is a red flag though, is it some unity anti-pattern

[leaden ice]

Then if you used Debug.Log, the code is working. What makes you think the renderer is not enabled?

DId you look at theinspector and see it still disabled?

[leaden ice]

absolutely yes

[soft nymph]

how so

[pallid barn]

Is there a specific reason that you're using transform.find as opposed to just a serialized reference to it?

[simple void]

It’s not efficient

You could find them in advance and cache it

[soft nymph]

thought it would be easier but its evidently not

[leaden ice]

Find is:

• Slow. It searches the entire scene for the name
• Fragile - renaming an object in the scene breaks it without any notice
• inconsistent - having multiple objects in the scene with the same name is possible and there's no way to differentiate
• It also can't find deactivated objects

[leaden ice]

Wait also you're uising transform.Find is that intentional?

Is this part of the same object hierarchy this script is on?

Sorry thought it was GameObject.Find

That's a different story

[soft nymph]

yes

[leaden ice]

Can you show some screenshots of the hierarchy and which components are on which objects?

[soft nymph]

i hope im not using a global find

voila

[leaden ice]

can you show the inspectors for the Player and FireEffect objects?

[kind nymph]

had to tweak it a bit but this works, now there's the problem of the function firing 4 times in a single press which i have absolutely no idea why thats happening, might take that to #🖱️┃input-system though idk

[soft nymph]

what do you want the player for? there is a lot there

[pallid barn]

Oh wait so the sprite renderer is stating as disabled? Are you then enabling it somewhere else??

[soft nymph]

correct

is there another way to make sprites invisible / visible?

[pallid barn]

Where is it that you're enabling it? That could be working against you trying to disable it in your dash code

[leaden ice]

Are you sure it's actually staying disabled though? Maybe it's just behind something

And can you show the full script

[soft nymph]

I already checked its order in layer is above all else

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

[soft nymph]

in a controller under Player

how else do people make sprites invisible if not disabling

[leaden ice]

they do disable and enable

something is wrong here because that works

[soft nymph]

huh

[leaden ice]

enabling and disabling is fine and works

so something else is going on here

[soft nymph]

im new to unity as an engine so prob some small setting

[leaden ice]

I'm still not totally convinced the code is actually running

[soft nymph]

it is.

[leaden ice]

having not seen the Debug.Log and the console

[soft nymph]

I can add it back again

im not sure why you dont take me at my word though

[vestal arch]

because when you've been working on something for a long time, sometimes you can miss small details. doesn't hurt to have another set of eyes to check over your work

happens to the best of us

[soft nymph]

Im a programmer by trade I understand that part

but I already assured him and checked myself twice that its running

I can send a video if you really want it

[vestal arch]

that would generally be preferable, yes

[leaden ice]

Because I deal with a lot of people here who are very new to Unity and think they did something but didn't actually do it, no matter how earnest and well intentioned they are

it's not a personal attack

[soft nymph]

I understand, I deal with that a lot too. But from someone who did programming as a trade for a while here is a video of it the code running

[vestal arch]

this server supports skill levels from Never Coded in my Life™️ to Has Been Coding Since Fortran™️, and frankly, we're not gonna remember who's who lol. we tend to have the same standard of "show your work".

[soft nymph]

Ah ok found the bug

[past elk]

Someone can help me. Im triying to do a movement by tiles, i create a empty gameobject with the tag "Tile" and i want the player move to the closest tile that is in front of him.

it is not a grid movement, because in each tile there is a different distance

[leaden ice]

if it's grid-based movement you would just keep track of the player's current grid coordinates, and when they move increment x or y by 1 in the appropriate direction. Then animate moving the player toward the corresponding world space location

[leaden ice]

So what is it

Can you share images/screenshots or an example of what you mean?

[past elk]

yep

The player is now in a tile, i want he moves to the next tile that is in front of him

[fallow quartz]

yeah i did that but the 2nd question was different

[past elk]

there is a tile empty gameobject to detect the tile in each tile

[leaden ice]

but how are tiles defined

[past elk]

with the tag "Tile"

[leaden ice]

but how do you define how they are connected?

[fallow quartz]

if I have a power up that moves on y axis a little bit and rotates, and then comes back to its position, and i want to use this animation in other 2 power ups, how can I do so when i spawn them not all of them have the same exact movement? I mean not on the same position but the movement being the same. I want one of them to start the animation in different keyframes so even they have the same anim they dont start in the same keyframe

[past elk]

i dont define any connection

[leaden ice]

Ideally you build up a graph (I mean this kind of graph: https://en.wikipedia.org/wiki/Graph_(abstract_data_type)) of tiles and then the player can navigate to whichever nodes in the graph are connected to his current node.

[fallow quartz]

And another thing, when i did what you said I had to move the prefab into the hierarchy, put it inside an empty object and then this new object save it as a prefab, is there a way to override the original prefab into the new prefab i want which is an empty object with the orighinal prefab as a child? So i dont have to create 2 different prefabs

[plucky inlet]

Not sure, what you really want here? But if you want to nest a prefab into itself, thats not possible

[sturdy stump]

Hey, is anyone able to help me with a small issue that i have?

[soft shard]

If you describe your issue and what you have tried, im sure someone may be able to help if they can/know about the issue

[mild goblet]

guys why does my GameObject spawn at its pivot point rather than its centre point

[somber nacelle]

because the pivot point is where it's transform.position is

[leaden ice]

That's what the pivot is. It's the actual location of the object according to the engine

[mild goblet]

okay following question. why is the pivot positioned at the bottom of my object.

[leaden ice]

That depends on what we're talking about here

is it a MeshRenderer?
A SpriteRenderer?

[mild goblet]

mesh renderer

i made my own mesh

[leaden ice]

Because that's where the origin/pivot of your 3D model is

[mild goblet]

okay how does one implement the origin of my mesh

is it the first vertex?

[leaden ice]

How do you change it you mean?

[mild goblet]

change yeah

[leaden ice]

It's the 0,0,0 coordinatre in the mesh's coordinate system

[leaden ice]

Depends on which 3d modeling software you're using

but.. just google, e.g. "Change mesh origin in blender"

[mild goblet]

oooh. i made a mesh in unity. 0,0,0 was at the bottom of my mesh

[leaden ice]

You mean ProBuilder?

[mild goblet]

nah just in code

[leaden ice]

oh then - it's just your code

0,0,0 is the pivot/origin

in terms of vertex coordinates

when you create the vertices you can just add some offset if you want to move the origin.

[mild goblet]

thank you i'll have a play around with the vertices

[spare dragon]

does anyone know where I could find the resources to develop a multiplayer DOTS game?

[fleet gorge]

resources? like learning materials?

https://docs.unity3d.com/Packages/com.unity.netcode@1.4/manual/index.html

if you're familiar with unity's netcode then this will help

[spare dragon]

thanks!

Hi all, getting to learn UI Toolkit on my own right now and I would like to get some help regarding order of operations or something else. My code returns this error when I try to set my gameobject to active.

Here is my code. I noticed that the Awake method runs even before the scene with the script is loaded. At least in the editor. This seems to result in my Visual Element being set to null. In what order should I run code in order to prevent my Pause Menu from being set to null in the controlling script?

public class UIController : MonoBehaviour
{
    public VisualElement m_ui;

    protected virtual void Awake()
    {
        m_ui = GetComponent<UIDocument>().rootVisualElement;
    }

    public virtual void Enable()
    {
        gameObject.SetActive(true);
    }

    public virtual void Disable()
    {
        gameObject.SetActive(false);
    }
}

public class PauseMenuController : UIController
{
    public GameSceneEventChannelSO _GameSceneEventChannelSO;

    public Button m_resumeButton;
    public Button m_restartButton;
    public Button m_exitButton;

    protected override void Awake()
    {
        base.Awake();
        gameObject.SetActive(false);
    }

    private void OnEnable()
    {
        Time.timeScale = 0;
        InstanceManager.Instance.isPlaying = false;

        m_resumeButton = m_ui.Q<Button>("btnResume");
        m_resumeButton.clicked += OnResumeButtonClicked;

        m_restartButton = m_ui.Q<Button>("btnRestart");
        m_restartButton.clicked += OnRestartButtonClicked;

        m_exitButton = m_ui.Q<Button>("btnExit");
        m_exitButton.clicked += OnExitButtonClicked;
    }

    private void OnResumeButtonClicked()
    {
        Time.timeScale = 1;
        InstanceManager.Instance.isPlaying = true;
        gameObject.SetActive(false);
    }

    private void OnRestartButtonClicked()
    {
        _GameSceneEventChannelSO.RaiseEventSceneChange(SceneManager.GetActiveScene().name, true);
    }

    private void OnExitButtonClicked()
    {
        _GameSceneEventChannelSO.RaiseEventSceneChange("Main", true);
        gameObject.SetActive(false);
    }
}

The structure of my scenes:

And would it be advisable to unsubscribe from the handlers on disable?

[stoic orbit]

I want to implement a game where I will have many characters. None of them share common characteristics, but many of them could share common abilities. For example, many could move with a basic movement, some could jump, some could control gravity, some could fly, and so on. To achieve this, I thought of creating components, like the PlayerMovement class, the PlayerJump class, the PlayerGravity class, where I will define parameters and methods. Then, for each type of cube (or player), I will use GetComponent and use the methods from these classes. For example, in the Player1 class, I will get the jump movement component, while in Player2, I will get the component and then use the methods from these classes
Each player will have different animations, but I could implement them in each script, for example in PlayerMovement, like this. I couldn’t create a separate animation script unless it's a different one for each player, or I could implement it directly in their respective controller.
Could someone give me some advjse??

[prime lintel]

solved: i had the ui document disabled in the inspector, as well as conflicting key press code that disabled the menu right after enabling

[unborn elm]

Maybe wrong channel but couldnt find a better one. Does anyone know if you can set tiles in tilemap to either be colliding or not, or do you need to make a seperate layer in order for it to collide?

Have a dual grid system so could maybe use my base grid to create collisions polygons, havent done that before though so not sure how to

[somber nacelle]

#🖼️┃2d-tools
but also you need to separate the collidable tiles onto a different tilemap

[unborn elm]

Ok, ill post there

[somber nacelle]

i mean, okay, but i did just answer your question so i don't see why you would need to repost it

[unborn elm]

Cool, what was your answer to this?
"Have a dual grid system so could maybe use my base grid to create collisions polygons, havent done that before though so not sure how to"

[somber nacelle]

yeah it's not even clear wtf that means if it isn't directly related to asking about your tiles being collidable. the tilemap collider applies to every tile assigned on the tilemap it is assigned to. therefore your collidable tiles will need to be on a separate tilemap

[unborn elm]

Great, then im happy to explain. Basicly I have a 50 * 50 grid that is beeing generated based on a texture input, this grid holds all relevant data. Then I have another grid offsetet by half a cell size that looks at the underlaying 4 cells in order to generate display tiles. This lets me get away with 16 tiles to cover all possible options and just needs basic binary addition in order to find the right tile

So I thought that using that to generate a collision map might be a good option.

[unborn elm]

Was that clear? @somber nacelle

[soft shard]

I want to implement a game where I will

[lost rivet]

i have a bit of a problem
public void myfunc(){
            myvirtualfunc();
    }

public virtual void myvirtualfunc(){
    }
i am running something like this, and the virtual function is called instead of its override, not sure why

[hexed pecan]

Show the actual code

Or at least the class and method signatures

[lost rivet]

only the names are different though, signatures are the same (its a simple script)

[hexed pecan]

Did you add the override modifier to the method in the child class?

[lost rivet]

yes

is this not supposed to happen? i was wondering if it was a c# thing

[hexed pecan]

This should call the overridden method, so you are doing something wrong

[lost rivet]

wait

when i call it inside a for loop it doesnt work, but in a foreach one it does huhhhh?

[hexed pecan]

Nobody can help without code

[still jungle]

probably you operates on 2 different types, in foreach you seems to cast it to what you want(what you expect to be correct) so it works, in for loop you operates on the base type so the virtual gets called

[thin aurora]

This is very unclear because there is no code here using the override keyword, please share this

One reason whyt his might happen is when you use the new keyword in a method signature. You should not be using this.

[rustic ember]

            Vector3 currentPointAlongToolAxis = GetPointAlongToolAxis();

            if (currentPointAlongToolAxis == Vector3.negativeInfinity)
            {
                return;
            }
            Debug.Log(currentPointAlongToolAxis);

            Vector3 newPos = currentPointAlongToolAxis - startPointAlongToolAxis + selectedPropPosBeforeMove;
            selectedProp.transform.position = newPos;

            // Move the tool objs to the new position
            toolObjsHolder.position = selectedProp.transform.position;
``` Is it not possible to compare a Vector3 to Vector3.negativeInfinity?

[leaden ice]

compare in what way?

[rustic ember]

GetPointAlongToolAxis() returns Vector3.negativeInfinity;

[leaden ice]

If you assign an object's position to infinity, that will be a problem.

[rustic ember]

In the If statement

[plucky inlet]

Imagine you are comparing something endlessly, imagine how long it would take 😉 forever probably

[vestal arch]

that's not how infinity works though.

[hexed pecan]

What about startPointAlongToolAxis and selectedPropPosBeforeMove?

[plucky inlet]

depends on the infinity 😉

[vestal arch]

not really, no

[plucky inlet]

Another conversation not really related to this I guess 😄

[vestal arch]

but definitely not helpful to the situation

[hexed pecan]

@rustic ember Ah nvm just saw you logging it before you use those

[leaden ice]

Looks like it should work: https://dotnetfiddle.net/xFhrQx

[hexed pecan]

Unity overrides Vector3 == operator, not sure if it works with infinity values

[leaden ice]

I think this is the key

[rustic ember]

Hmm... 🤔

[leaden ice]

nvm just saw that lol

[rustic ember]

Ahah

[vestal arch]

public static bool operator ==(Vector3 lhs, Vector3 rhs)
{
    float num = lhs.x - rhs.x;
    float num2 = lhs.y - rhs.y;
    float num3 = lhs.z - rhs.z;
    float num4 = num * num + num2 * num2 + num3 * num3;
    return num4 < 9.9999994E-11f;
}

[hexed pecan]

But it is logged as infinity before those values are used 🤔

[vestal arch]

im pretty sure that results in a bunch of NaN

so yes the comparison would not work

[leaden ice]

https://github.com/Unity-Technologies/UnityCsReference/blob/2940f42ee1788b7e6b78240303b1597cec984c56/Runtime/Export/Math/Vector3.cs#L463

Yeah here's the problem

return sqrmag < kEpsilon * kEpsilon;

is not going to work properly for infinity

[hexed pecan]

Equals probably works

[vestal arch]

any difference of infinities would result in NaN

[hexed pecan]

It just compares x y and z with ==

[vestal arch]

oh, so that's what the difference between those 2 are

[rustic ember]

"// Returns false in the presence of NaN values." Is infinity a NaN value? Or just a really high value?

[plucky inlet]

you could compare your values to mathf.infinity tho and then clamp them to 0 for example

[vestal arch]

-Infinity - -Infinity is NaN

[vestal arch]

that's what he's trying to do

[hexed pecan]

Try if(currentPointAlongToolAxis .Equals(Vector3.negativeInfinitiy))

[vestal arch]

@rustic ember are you aware with floating-point values as a concept?

[rustic ember]

What if it was positive infinity instead?

[plucky inlet]

He is comparing to vector3.infininity, not mathf. to the separate axis

[rustic ember]

Yes

[vestal arch]

Infinity - Infinity is also NaN

[leaden ice]

https://dotnetfiddle.net/cJWyLx

[rustic ember]

That makes no sense to me. It should be 0 right?

[plucky inlet]

Infinity is not defined, so no value to substract from the "no value" infinity

[vestal arch]

Vector3.positiveInfinity and negativeInfinity use float.Pos/Neg Infinity

[vestal arch]

this is wrong.

[plucky inlet]

How is it wrong? whats right?

[rustic ember]

But I could use Vector3.one * 1000000?

[leaden ice]

ahhhhhh nope lol

[rustic ember]

B-but... But math?

[leaden ice]

Yes, infiinity is weird

[vestal arch]

floating-points are not exact, they are approximations
0 is an approximation for anything that's too small (magnitude) to represent as a non-zero value; that's why there's -0 and 0, for positive and negative close-to-zero values
±Infinity are approximations for anything that's too big (magnitude) to represent as a finite value
so when you have 2 values that are represented by Infinity, you don't actually know if one is bigger than the other

[leaden ice]

https://www.wolframalpha.com/input?i=infinity+-+infinity

It's not 0 even if you had perfect floating points

[vestal arch]

10f**1000f and 10f**1001f are both Infinity, if you subtract them, you shouldn't get 0

you wouldn't really know what else to give though; it's impossible to reasonably represent, so you get NaN

[rustic ember]

But this would work right?

[leaden ice]

What are you actually trying to do here

use a magic value to represent something?

Why don't you use Vector3? (nullable)

[vestal arch]

this is also why x/±0 where x is any non-zero value will result in ±Infinity, but ±0/±0 will give NaN

[hexed pecan]

Both ways are valid IMO

[vestal arch]

Infinity is well-defined for floating-points

this isn't math

this is an approximation of math for computers to use

see IEEE 754

[rustic ember]

I should have probably explained this from the beginning.

        Vector3 pointAlongAxis = Vector3.negativeInfinity;
        if (plane.Raycast(ray, out float _enter))
        {
            Vector3 hitPoint = ray.GetPoint(_enter);
            pointAlongAxis = Vector3.Project(hitPoint, b - a) + a;
        }

        return pointAlongAxis;``` This is what teh GetPointAlongToolAxis() method is doing. I just figured I could return Vector3.negativeInfinity if the ray didn't hit the plane

[rustic ember]

Right!

[vestal arch]

you could also use a Try pattern

[leaden ice]

I would either:

• replicate the TryGet pattern in THIS method as well
• Return a Vector3?

[rustic ember]

I could just return null

[plucky inlet]

But just to conclude my suggestion, this one

        Debug.Log("Vector3: " + (infVector == Vector3.positiveInfinity));
        Debug.Log("Float: " + (infVector.x == Mathf.Infinity));

results in this screenshot

[vestal arch]

not directly for a Vector3, it's a value type, it can't be null

[plucky inlet]

So thats what you could do to check if its infinity

[vestal arch]

because == is overloaded for Vector3 to do an epsilon check, not an equality check. you would use Equals instead, like osmal mentioned

[leaden ice]

public bool TryFindPoint(Plane plane, Ray ray, out Vector3 pointAlongAxis) {
    if (plane.Raycast(ray, out float _enter))
    {
          Vector3 hitPoint = ray.GetPoint(_enter);
          pointAlongAxis = Vector3.Project(hitPoint, b - a) + a;
          return true;
    }

    pointAlongAxis = default;
    return false;
}```

Using the Try pattern^

[plucky inlet]

Ah, guess I missed the confirmation

[vestal arch]

@plucky inlet

[prime lintel]

Hi, I am having massive trouble with working with UI Toolkit scripting.

What load order here could be incorrect such that my InstanceManager is still null? This is not a problem in the editor, only built executables have this issue.

[plucky inlet]

Where do you set the instance? And why are you setting booleans of another class in your mainmenuclass, if its not on method call but on enable? Or does your mainmenu get enabled later?

[vestal arch]

well if MainMenuController is loaded first, then that would be an issue
Awake+OnEnable are called together for each object (ref: #archived-code-general message)

[prime lintel]

The InstancManager is a persistent singleton of many Managers. It is instantiated on load in the scene entry point of the game.

I am unfortunately struggling to get something as basic as buttons to function so I have been hacking my code apart in search of a working method.

public class InstanceManager : MonoBehaviour
{
    public static InstanceManager Instance { get; private set; }

    [Header("Managers")]
    public AudioManager audioManager;
    public GameSceneManager gameSceneManager;
    public InterfaceManager interfaceManager;
    public TimerManager timerManager;
    public ICineMachine iCineMachine;
    public AstarPath aStarPath;

    public bool isInMainMenu = true;
    public bool isPlaying = false;

    private void Awake()
    {
        audioManager = GetComponent<AudioManager>();
        gameSceneManager = GetComponent<GameSceneManager>();
        interfaceManager = GetComponent<InterfaceManager>();
        timerManager = GetComponent<TimerManager>();
        iCineMachine = GetComponent<ICineMachine>();
        aStarPath = GetComponent<AstarPath>();

        if (Instance != null && Instance != this)
            Destroy(this);
        else
            Instance = this;

        DontDestroyOnLoad(gameObject);
    }
}

[prime lintel]

Does the order in which game objects are listed in the scene affect this?

In fact, I don't really have any idea on what the standard practises for holding UI Documents and Scripts is for Unity. Would it be possible to point me in the right direction please?

[plucky inlet]

You should not at all rely on your hierarchy to drive your scripts execution. Rather have something control your flow of data and enable/disable depending on states rather then just all at once

[prime lintel]

For example, should UI Documents and associated scripts be all persistent singletons that persist across all scenes?

[plucky inlet]

your InstanceManager is instantiated?

[prime lintel]

So in this case, perhaps my UI game objects should be enabled and disabled based on a controller

[prime lintel]

It sure is, else my game would not function past a blank screen

[plucky inlet]

Okay, but then you really have to get a statemachine going to tell your game, what is happening. First, setup of managers or what not, like your instancemanager, then setup the UI with your controllers and so on.

[prime lintel]

Okay, I'll try that. Thank you

[prime lintel]

Would it be advisable to use SOs to function as event channels for communication between locations where calls to enable and disable UI documents?

[plucky inlet]

Not really. SOs should be used as data providers.

You rather have some kind of UI Manager reacting to for example gamemanager states or user inputs and what not

[prime quarry]

when activating the debugger in visual studio it sometimes causes unity to infinate load so that i cant launch the game or do anything, it happens off and on but sometimes it can persist making it impossible to debug, does anyone know anything about this issue?

[placid summit]

async tasks in Unity continue after play mode has stopped...

I think I need UniTask...?! Which avoids such things by default?

[placid summit]

It can be slow but is not infinite for me at least. However if I cancel debugging while on a break point in VS then I have to wait WAAAYYYY too long!

[tired elk]

Or you can add a Cancellation Token that is triggered by EditorApplication.playModeStateChanged

[placid summit]

Yes so I read this but seems like I would be adding coding overhead. however the doc does also not actually give an example where as seems like this should be checked everywhere

Do async tasks end on closing a .Net app, is this some unity issue? What would be a reason to allow tasks to continue?

[chilly surge]

Your editor isn't closed when you exit play mode.

[leaden ice]

Indeed. Interesting discussion recently here: https://discussions.unity.com/t/on-async-await-with-awaitables-as-a-coroutine-replacement/1554090

[placid summit]

Erm yeah fine for editor code, but you can run async code in play mode, stop playing your app and it continues to mess with your scene in the background!

[craggy veldt]

yeah, you would need MonoBehaviour.destroyCancellationToken which should be available in 2023 and above

wait, I think Unitask is doing that already via it's own custom playerloop, oh you're not using uitask,, misread, yeah you need the method above

[chilly surge]

That's what I'm pointing out with the .NET app comparison, when you close the .NET app, the entire process is gone and dead, but exiting play mode isn't comparable because the editor process is still very much alive and kicking.

[thin aurora]

Doesn't Unity cancel running asynchronous processes through cancellation tokens?

[craggy veldt]

it doesnt, thats why they give us MonoBehaviour.destroyCancellationToken

[thin aurora]

It does exist: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Application-exitCancellationToken.html

So if you combine your cancellation tokens with this (assuming you use them), you can cancel running Task instances

@placid summit ☝️

[chilly surge]

I will continue to recommend UniTask 😄

[thin aurora]

What does UniTask have to do with cancelling the Task? Does it do it automatically?

[craggy veldt]

unitask uses it's own custom player loop, which is based on the undocumented PlayerLoop

it can cancel all tokens when exitting the editor properly

[leaden solstice]

Is PlayerLoop still undocumented

[thin aurora]

Neat, can definitely be beneficial there

I assume this can be configured so I can keep tasks running? I can imagine you might want this

[placid summit]

Does UniTask just cancel all tasks on exiting play mode in editor?

(play mode tasks)

Really the problem is glTFast decided to scatter Task throughout its codebase and I have to deal with Tasks now

[cold parrot]

depends how how you started them, there is no guarantee.

[craggy veldt]

barely

[thin aurora]

I haven't used UniTask but it sounds very useful to have

I do think it would be overkill to pick it when you can just use the CancellationToken, but at least a nice alternative to consider

I feel like having control with CancellationTokens would be so much easier to manage, though perhaps prone to issues if you forget to implement them

[cold parrot]

if you do anything with tasks, unitask is not overkill, regular tasks in unity have so many gotchas you need to know about

[leaden solstice]

Awaitable is meh

[thin aurora]

Ah, I wasn't aware of that.

It seemed pretty well thought out

[cold parrot]

it (UniTask) is one of those packages made by someone with extensive experience with real world problems they wanted solved

[craggy veldt]

not sure what that means, but Awaitable is quite lacking of useful methods like what regular Tasks has

Unitask covers most of those

[placid summit]

Awaitable does exit at end of play mode?!

[cold parrot]

try it

its best to not rely on it and always pass a onDestroyCancellationToken that every component has

[placid summit]

it seems to exit, but I know nothing of using tokens

[cold parrot]

then you should learn about them, you can't use tasks sensibly without them

by default a (runaway) task will only automatically terminate when the process (App) that owns it is terminated

[steady bobcat]

async functions wont stop when playmode ends unless a cancellation token is used, you check for null or an exception is thrown

unitask tracker can help you check this (if using unitask that is)

[craggy veldt]

its more than just terminated, you'd need to properly dispose them, even when they're cancelled/completed, they can leak in the grand scheme of things

[steady bobcat]

you cant leak program owned memory when the process terminates...

[latent latch]

So everyone still using Unitask? Havent looked into awaitables yet

not that any of this stuff works for webgl :(

[steady bobcat]

must be a webasm limitation and well js "threads" are a joke

[chilly surge]

JS is fully capable of multi threading.

[latent latch]

but hey, I'm blowing up peoples GPUs overhere

[chilly surge]

It's also up to the runtime (not the language) to provide multi threading capabilities, and all popular runtimes have them, eg web workers in browsers, Node.js workers in Node.js, etc.

[thin aurora]

This is something you should definitely learn. It's heavily used, even outside Unity

It's the main way to stop asynchronous Tasks from running gracefully

Or not gracefully, that's also possible 😄

[latent latch]

but ya know, spectre vulnerability and stuff and services don't want to support them

https://caniuse.com/sharedarraybuffer

[placid summit]

awaitable does not have Forget() so... seems annoying. How should an Awaitable be triggered from a synchronous function to avoid warning?

[wheat spruce]

There are that many browsers?

[vestal arch]

and devices
probably multiplying the 2

[craggy veldt]

they support discard iirc _= MyAsyncMethod()

[wheat spruce]

1998 devices
Firefox,
Chrome

[thin aurora]

As in a fire and forget method? I'm not sure how Awaitables work in this matter but the base Task based system just allows you to call itself and discard the task without awaiting it

Alternatively, Task.Run for true background tasks exist in case the method is blocking before it would ever switch its context

// This can block the main thread in some cases
_ = FooAsync();

// This never blocks
_ = Task.Run(FooAsync);

[calm echo]

    {
        public static async void FireAndForget(this System.Threading.Tasks.Task task)
        {
#if UNITY_EDITOR || UNITY_DEVELOPMENT
            try
            {
                await task;
            }
            catch (Exception e)
            {
                Debug.LogError(e);
            }
#else
      await task;
#endif
        }

        public static async void FireAndForget(this Awaitable awaitable)
        {
#if UNITY_EDITOR || UNITY_DEVELOPMENT
            try
            {
                await awaitable;
            }
            catch (Exception e)
            {
                Debug.LogError(e);
            }
#else
        await awaitable;
#endif
        }```

[thin aurora]

Note that you should always make sure to gracefully handle these methods in a way where you manually try-catch the method to avoid it getting ignored

[steady bobcat]

you can do #if DEBUG (which is true for editor and dev builds)

[thin aurora]

I don't think it matters as much with Unity, though. The console would show any errors. The issue is that it might break your application

[calm echo]

incorrect, unity does not catch threaded errors

[placid summit]

yeah async void call and then do awaitable. ah anyway I am probably screwed as glTFast uses Task - seems like an over sight to me that it does so

[steady bobcat]

you mean it doesnt print them in the console

[thin aurora]

I was specifically talking about them being printed in the console in any way

I didn't say Unity would catch them

[calm echo]

yeah i mean they are silent

they wont be in the consle

[thin aurora]

.NET has TaskScheduler.UnobservedTaskException, I don't know if you can use it here

I assume Unity would have something similar for this

[calm echo]

thats why you wrap your fire and forget in a try catch in debug scenarios

[thin aurora]

Yeah but your log is not gonna help much in production

[calm echo]

or else the errors will go completly silent in the background

[thin aurora]

But you're right, at least silent exceptions are not the case

[vestal arch]

no like 40 browsers and 50 devices -> 2000 combos

[thin aurora]

Does Unity have an event similar to this? #archived-code-general message

Or do Awaitables also hook on this?

[calm echo]

I would stay away from task in newer version of Unity. I am unsure how the Unity context and task shecudler works. I dont beleive its default implimentation though

[craggy veldt]

why?

[cold parrot]

you can do

public static class TaskExtensions
{
    /// <summary>
    /// Wraps a fire-and-forget task in a try-catch block to prevent unobserved task exceptions. Also silences the
    /// related roslyn warning.
    /// </summary>
    public static void Forget(this Task task)
    {
        var awaiter = task.GetAwaiter();
        if (awaiter.IsCompleted)
        {
            try
            {
                awaiter.GetResult();
            }
            catch (Exception ex)
            {
                PublishUnobservedTaskException(ex);
            }
        }
        else
        {
            awaiter.OnCompleted(() =>
            {
                try
                {
                    awaiter.GetResult();
                }
                catch (Exception ex)
                {
                    PublishUnobservedTaskException(ex);
                }
            });
        }
    }
}

[chilly surge]

SharedArrayBuffer is not required to do multithreading in JS, that's like saying "C# must have ConcurrentDictionary to do multithreading."

[craggy veldt]

what is this 😅 ...
GetAwaiter/getresult can deadlock

[thin aurora]

Bit less related but .NET also has AppDomain.UnhandledException for exceptions in general

Again idk if Unity works as good with this and/or if it has an alternative. Would love to know if it does

[latent latch]

So what's the reasoning that WebGL still has no actual multi-threaded support? SharedArrayBuffers were suggested but eventually were deprecated years ago and not since have Unity added an alternative.

As it seems, they're more focus with WebGPU at the moment and completely abandoning any threaded support it seems

[calm echo]

I guess the move to webgpu?

[latent latch]

Which works great^

[calm echo]

WebGl is kinda dead

[chilly surge]

The conversation started on JS multithreading and now seemingly it has moved to WebGL/WebGPU?

[latent latch]

The dicussion was about awaitables and unitask not working with WebGL

because at the moment there is no async operations

[chilly surge]

WebGL is a technology that enables JS to access to GPU in browser, I don't think that's really what you meant. What you meant is probably "why doesn't Unity's web target platform support multithreading" in which case the answer is just, Unity doesn't support it.

[steady bobcat]

UniTask does something similar so id trust it! https://github.com/Cysharp/UniTask/blob/master/src/UniTask/Assets/Plugins/UniTask/Runtime/UniTaskExtensions.cs#L552-L583

[latent latch]

I would think there's a bit more to it than just "not support it" considering it was one of the largest focuses with Unity 6.

[chilly surge]

There's no technological limitation where multithreading cannot be done in web browser, you can literally use it right this moment: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers

As for why Unity doesn't support it, that's a question that has to be answered by Unity, maybe it's architectural reasons, maybe it's legacy, maybe it's something else.

[latent latch]

I'm just saying. If it was that easy to implement, you'd think Unity's team working with WebGL would be on it

[cold parrot]

"unitask guy understands more about tasks than anyone in here" is my heursitic

[latent latch]

I'm not a web dev, but I've been doing a bunch of webgl games for a decade now

Anyway as it seems, any async operations will be done through compute shader with how the preview went

that's the future for WebGL/GPU with Unity

Related, Godot abandoned multi-threaded support for their web exports

[chilly surge]

There are quite a few things going on in this conversation, I'm still failing to grasp why multithreading in JS has anything to do with WebGL/WebGPU, but I think I've cleared up the point pretty clearly that web does support multithreading just fine, and it's up to Unity/Godot/Blazor/whatever to make use of that underlying technology.

[steady bobcat]

does unity use webasm or js for user code cus im not really sure?

[chilly surge]

That doesn't matter because WASM and JS can interop.

WASM cannot even run without a bit of bootstrap JS.

ah ill ask in #🧰┃ui-toolkit

[rigid island]

doubt input system is related to this

[prime lintel]

where should i put the logs? i know for sure the methods assigned the the event doesnt run at all

[rigid island]

hmm its always good to put assumptions aside with proper tests

also not entirely sure if UIToolkit needs the Event System for the new Input Module to work , double check that too

[rigid island]

what kind of answer are you looking for then ? Programming takes years of built up knowledge, GPT doesn't work especially when you cannot differentiate between truth or hallucinations

[unkempt swallow]

you are being very negative and condescending because you seem to have some hate against gpt, even tho it can be a valuable help, id like to not converse with you any further since you clearly did not understand my question and just got triggered, thanks

[vestal arch]

it can be a valuable help

it's a tool

it's not a replacement for experience

in particular, you need experience to be able to utilize it effectively, when correctness matters

[rigid island]

no problem. I just block and move on 🙂 goodluck friendo..

[still jungle]

it does good for sources lookup with web option, but generated prompt is falsy true in most of cases of advanced questions

[unkempt swallow]

correct, if youve read my question you can understand that i obviously tried gpt and with my experience and knowledge noticed that its barely any help at all if it is about topics other than basic code fundamentals, thats why im asking if there are more advanced solutions , specifically for programming related questions, in my example i asked gpt for help with a rarity algrithm because my own wasnt good enough, the results ive gotten were worse if not wrong most of the time

[vestal arch]

you should not rely on AI help in general
consider building up researching skills, for example how to use google search syntax effectively
the internet has a lot of info, just gotta find where it is

thats why im asking if there are more advanced solutions , specifically for programming related questions
with AI? no

[unkempt swallow]

a tool is a tool, you shouldnt not rely on X because of Y is really narrowminded

[vestal arch]

just not really how AI works

[latent latch]

If you're looking up algs, always ask for references for where that information was gained if you want more insight and not be too reliant on it

it usually will provide you some direction

[vestal arch]

you shouldn't rely on tools in general, no? you should be able to work without them. tools make stuff easier if you can use them properly

[unkempt swallow]

im more annoyed by the fact that gpt is presenting it as correct, when anyone with 2 braincells can tell that its not, thats why im looking for an alternative to it xd

[vestal arch]

gpt isn't special; none of the chatbots are special

[unkempt swallow]

yeah, stop using unity man, machinecode it is :)

thank you, thats why im asking, that was my question but someone got so triggered by me asking about AI lol, if there isnt, im ok with that, just wanted to know i dont keep close eyes on gpt development etc

google search is usless nowadays

[latent latch]

google has been useless since people started gaming the alg and all those "Top ten" blogs started to spam the top results

but as a rule of thumb, ai is discouraged in many, many places

ai isn't as useful as the marketing would lead you to believe
it's great for pattern matching, so for research and industrial automation that depends on that, and not much else

[unkempt swallow]

i noticed, gpt barely provides any valueable info lmao its actually really really dumb

[vestal arch]

that's LLMs in general

[unkempt swallow]

with all the hype and youtube videos i thought that it would be atleast usefull for low level programming questions but it fails at even that

[chilly surge]

I would strongly recommend people to take a look at how LLMs generate texts, you don't need a ML degree, just a simple overview of how it works and you will immediately understand why they are not reliable: the last step of generating text is literally rolling a dice and picking a token based on probability.

[unkempt swallow]

really sad

[chilly surge]

I don't need correctness from a dice.

[vestal arch]

it's a "new" technology (at least to the general public), and that's a double edged sword, because people with financial incentives can lie about it and the general public wouldn't know any better

[unkempt swallow]

never looked at it that way but youre right yeah, i used to use gpt in the early days as a better way to get the info i would have gotten through google, but since google is barely useable aswell, well here we are

[vestal arch]

same thing with crypto and blockchain and nfts, see all the scams the past few years where they never actually took off

[still jungle]

wouldnt say that, but yes some feel overconfidemt because they sit with one technology for long and thinks that they know everything but its not the case, those people help for free so its very valuable for others so dont see a reason to argue with them

[vestal arch]

they're useful, but not as useful as they're claimed to be

[unkempt swallow]

well then let me ask my question here, im trying to programm rarity, 0 to 100, lower values being more common, how would you do it? i got sth that is fine thanks to gpt for now, but im still lost and not reaaaally happy with it since it has a lot of 1 and isnt as spread around the lower values, as i want it to be

[vestal arch]

that's hilarious compared to youtube putting suicide help lines on videos that say something tangentially related once lmao

[vestal arch]

use the rarity as a weight

[unkempt swallow]

this is what ive got

public int GetRandomRarity(float rarityWeight = 2.0f)
    {
        // Step 1: Generate a random value between 0 and 1
        float randomValue = Random.value;

        // Step 2: Apply the rarity weighting formula
        // Lower values are more likely; higher values become rarer
        float weightedValue = Mathf.Pow(randomValue, rarityWeight);

        // Step 3: Scale the result to the range (1-100)
        int rarity = Mathf.CeilToInt(weightedValue * 100);

        return Mathf.Clamp(rarity, 1, 100);
    }

[vestal arch]

i guess like, 100 - rarity, as the weight, rather

[unkempt swallow]

using a weight of 5 works fine, but the lower values are like i said, not as spread as i want

[vestal arch]

oh hold on

[chilly surge]

Depends on how you are using it, if you are using AI to lead you to the source material then sure, if you are just using AI to regurgitate information then that's not a justified use case.
Unlike source materials where the author's reputation is at risk, LLMs are never held accountable no matter how many times it gives you crap. If I keep giving wrong information here in this chat, I will be called out for it, but someone will always make excuses for AI "yeah maybe this time the dice just didn't roll the right way."

[vestal arch]

what's the input/output?

i thought you meant rarity (0-100) input, and then a yes/no or a selection output

[unkempt swallow]

nope

you fish a fish, then roll for weight 0 to 100, but i want it to be more common to get values 1-30ish, and 90+ should be rare enough for it to only be there once or twice in 100 rolls

[vestal arch]

ah ok

[heady iris]

are we talking about ✨ distributions ✨ ?

[vestal arch]

so are you just kinda, mapping the randomvalue from 0-1 to 0-100 with a bias towards lower numbers?

[latent latch]

https://github.com/mackysoft/Choice
I usually do that for weighted items

[vestal arch]

gotta find a pdf for this then lol

[latent latch]

mackysoft always got the goods

[heady iris]

a cdf is more useful (:

[vestal arch]

ah, true

[unkempt swallow]

yes

[heady iris]

well, an inverse cdf

[vestal arch]

but a pdf would be more easily mappable to code wouldn't it

[heady iris]

An inverse cumulative distribution function lets you sample a uniform random value and then compute a value from the distribution

[chilly surge]

The simplest system would just be defining a list of all possible outcomes and their weights.

[heady iris]

the density function isn't too helpful on its own: you can't use it to sample from the distribution

[heady iris]

Yes -- this is a great idea if you don't intend to give a very rigid meaning to each rarity tier

Also, you can get pretty far by doing very basic reshaping of a uniform distribution

[unkempt swallow]

yeah i could yanderedev this but i thought about having a fancy rarity function i might use again for sth else

[heady iris]

For example:

float BiasedRandom() {
  return Mathf.Pow(Random.value, 2);
}

This gives you more small numbers

[chilly surge]

It's so much simpler to maintain a uniformed distribution and map it to a weight table, than doing some fancy math. It's not about being "YandereDev garbage code," you can have a well written simple system just fine.

Being complex doesn't mean it's automatically better, being simple doesn't mean the code has to be garbage.

[heady iris]

sometimes it is most practical to just enumerate every outcome

[unkempt swallow]

then i missunderstood, but how would you do that for values 1 to 1000 ?

hard code a weight for each value? thats madness

[latent latch]

That mackysoft has a nice overview on the search algs with some graphs for different search algs

[heady iris]

do you need 1000 values?

[vestal arch]

you could just define statically-set ranges, then add random variation to the middle value

[unkempt swallow]

yes, maybe even 10000

[latent latch]

enuemrate is probably fine

[chilly surge]

I'm not sure why you would need 1000 values, you only need as many values as the amount of outcomes there are, eg if there are 3 possible types of fish you can fish up then all you need just 3 values (one for each type of fish) and that's it.

[vestal arch]

wow i have no idea what i'm doing

[unkempt swallow]

??? i dont understand what you are saying sorry

[vestal arch]

this would be a cdf, right? @heady iris

[unkempt swallow]

fish have a weight float, which i want to be between 1 and lets say 10000

i could use a simple random.value but thats not what i want

i want higher values to be very rare

lower values to be spread well

[chilly surge]

You still need to define "very rare"

[heady iris]

no, for a few reasons (including because it's decreasing, and because its integral isn't 1)

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

[vestal arch]

wouldn't it be a pdf if the integral was 1

[heady iris]

oops, yes, that was backwards.

it should reach 1 (:

[vestal arch]

ah, of course

[latent latch]

https://www.peterstefek.me/alias-method.html

[chilly surge]

10000 is a meaningless number if you don't give it a well defined value, what you are trying to do is that you have some vague definition of rarity (high number = very rare) and trying to find some mathematical algorithm to match that vaguely unspecified rarity number. What does 10000 mean in relation to 10? Does it mean it's 1000x rarer? 3 times (10^3) rarer?
Is there a reason why you are not doing the typical approach to loot table?

[vestal arch]

i was thinking x being the randomValue input, and y being the weight output
so for the curve i showed, it'd be a 50% chance to get >7, 20% to get >40, etc

does that make sense (asking fen)

oh this is the inverse cdf you mentioned, right?

[heady iris]

Perhaps you have the opposite question

[unkempt swallow]

because i thought there is some sort of math algorithm for exactly that, you could rewrite my question into simple words like
i want to roll for a number between 1 to 1000 but have the result be weighted towards 1-500 with a variable i can adjust

[heady iris]

"How can I turn a weight value into a rarity tier to show to the player?"

It seems a bit weird to be talking about rolling between 1 and 100, or between 1 and 1000

[chilly surge]

What about the simplest loot table approach that's used by practically every game?

[heady iris]

you can choose whatever range you want

[unkempt swallow]

how would you make a loot table for weights that go from 1 to 10000 ?

[heady iris]

why do you need 10000 different rarity values?

[vestal arch]

you don't, that's not what they're suggesting

[heady iris]

you've gotten obsessed with specific large numbers here

[unkempt swallow]

i think you guys are getting confused by weights and weights of the fish as in kg

[chilly surge]

You are too hyper focused on the arbitrary number of 10000, where you can't even define what "10000" means.

[heady iris]

no, we know what's being described

[unkempt swallow]

no im changing the number because you are focused on that when it shouldnt matter at all

the upper limit should be whatever number i want whenever

[vestal arch]

just to make sure we're on the same page here; there's no rarity, is there?

just a weight (physical quantity) that needs to be distributed

[latent latch]

if there's not rarity then that would change the problem completely

[unkempt swallow]

you catch a fish
code rolls a magic number, this magic number is the weight of the fish
the weight can range from 1 kg to 100kg or whatever i define as the max weight for it, maybe 10000kg its up to me
i want the roll to be weighted towards lower kg results, idk lets say 1 to half of the max kg
and the high kg numbers to be weighted rarer, lets see 70 to 100% of the number

if we stick with 1 to 100 then 1 - 50 should be common, 50-70 should be uncommon and 70-100 should be very rare

is that more understandable

[heady iris]

the mass of a fish would be decided by a normal distribution

this would give you very reasonable results (with some clamping required to avoid things like a very rare -10kg fish)

[unkempt swallow]

wdym with normal distribution ? i dont understand

[polar marten]

are you asking how to turn a uniformly random number into one that belongs to a specific distribution?

[vestal arch]

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

[chilly surge]

In that case, you can pick any kind of curve you want, and the integral of the curve from 0 to x over integral from 0 to max will represent the chance of getting x.

[vestal arch]

wow, thanks for the embed, wikipedia

[vestal arch]

yeah, i connected the dots a bit ago though; no need to explain it to me

[unkempt swallow]

that brings me back to my original gpt question lmao, how do i do that? im shit at mad at mediocre at c# at best, never really worked with algorithms formulas and math

[heady iris]

#💻┃code-beginner message

I've described the process here

[chilly surge]

You can calculate the integral from 0 to max given the known curve and max, randomize a number between 0 and the result, then reverse the calculation to retreive x.

[unkempt swallow]

ty, ill look into normal/gaussian distribution

[heady iris]

The "secret sauce" here is the function that maps from a uniformly random value to the normal distribution.

[vestal arch]

you aren't going to need algorithms for this; do you know some basics about statistics?

[unkempt swallow]

school basics 💀

[chilly surge]

You don't need a specific curve, literally any differentiable curve will work.

[vestal arch]

that varies wildly 😭

[unkempt swallow]

i would rate myself in Math with an D

ill be fine with keywords i can google and research

[vestal arch]

but there's so many levels of math that the rating is almost meaningless lmao

[polar marten]

use a library. there aren't closed analytics for all of these. if it's important for you to sample with any mean and variance for normal for example. for real stuff you almost always want lognormal.

[vestal arch]

anyways you'll probably want to figure out how distributions work

[polar marten]

don't worry about the math. use a library

[vestal arch]

im not the one asking

[latent latch]

there's plenty of these algs laying around, especially related to games since it's a pretty common problem

[polar marten]

ah

[heady iris]

I have not carefully inspected the math behind the code linked here, indeed

and I don't have to!

[polar marten]

https://github.com/VoxusSoftware/unity-random

[unkempt swallow]

is there a magical place for them or do you guys have a secret to not get shitty google results

[heady iris]

iirc it's an approximation of the inverse CDF -- which I believe there is no analytic form for

[polar marten]

google search is "unity random distributions library github"

[unkempt swallow]

if not shitty, half the results are malicious ads

[polar marten]

there are lots of options

[vestal arch]

here's the secret: https://support.google.com/websearch/answer/2466433?hl=en

[unkempt swallow]

that is exactly what i wanted holy shit

[vestal arch]

wow that article lists so little

[polar marten]

add "Github" or "reddit" to your search

[chilly surge]

^ I feel like people are too focused on a solution for a specific curve, the general calculation outlined here works for any curve, whether it's Gaussian, normal distribution, f(x) = whatever*math/equation+here.

[polar marten]

there is no general calculation for a normal distribution which is why nobody teaches it.

[latent latch]

that repository is basically what fen linked

[chilly surge]

Replace from 0 to max with from min to max and you can expand it to any range including infinity.

[polar marten]

there's no analytic inverse cdf for gaussian

[vestal arch]

https://docs.google.com/document/d/1ydVaJJeL1EYbWtlfj9TPfBTE5IBADkQfZrQaBZxqXGs/edit?tab=t.0

[polar marten]

in games you never want gaussian

you want lognormal, bernoulli, and hypergeometric

[unkempt swallow]

this is what i wanted in code form but able to adjust the curve to my liking

[polar marten]

this is an exponential distribution. the discrete version (probably what you want) with two parameters is pareto

the thing i linked has exponential

[vestal arch]

im pretty sure that's not exponential

[polar marten]

🥺

i know a lot about this guys

[vestal arch]

it wouldn't asymtoted on both axes, no?

[polar marten]

he doesn't know what he wants

i'm trying to give him the answer in light of that

[unkempt swallow]

so real

[magic tusk]

Hey guys, I have a quick question about CloudSaveService
I want to do CloudSaveService.Instance.Data.Player.LoadAllAsync, which returns a dictionary<string, Item>
So if I modify this dictionary I later want to save it with CloudSaveService.Instance.Data.Player.SaveAsync
but that takes a dictionary<string, object>..
Is there an easy conversion between these two I have missed?

To anyone that finds this:
I used .GetAsString() and stored all intermediate data as strings...

[vestal arch]

you said "this is an exponential distribution" though, which, well, is it?

[chilly surge]

And simply integrate the curve from x = 0 to x = 100 to get the sum (represents area under curve), uniformly randomize between 0 to sum, reverse the integral and you get back the x that's randomized weighted according to that curve.

[polar marten]

well that's just a drawing

that's what it is

[chilly surge]

This process works for literally any curve, given that the curve is differentiable.

[vestal arch]

but it's much closer to say, 1/x than an exponential function

[polar marten]

massive plead emoji

[latent latch]

can always just integrate python and use some numpy

[polar marten]

try the exponential function from that library. it really depends what you want to do

[vestal arch]

like im confused what you're trying to say here

[polar marten]

what is the gameplay goal?

for pulling stuff out of a bag, that is, most game behaviors, including modeling pity, you want hypergeometric

it really depends on your gameplay goal

[unkempt swallow]

this is the gameplay goal

[vestal arch]

it sounds like you're saying "you want an exponential function", but you said that what they drew was an exponential function
so like, what's your claim here

[unkempt swallow]

having high weight(KG) = better

[polar marten]

do you want pity?

do you know what that is?

[unkempt swallow]

no pity

just harsh randomness (weighted)

[latent latch]

really if there's not catagorizing it's just a curve you throw a dice at

[polar marten]

common, uncommon, rare, "legendary" kind of has some player expectations to it. is that important to you?

[unkempt swallow]

no

[polar marten]

sometimes the best way to model this is to create a deck of 100 fish, and draw from it. this will have pity built in.
otherwise, if it's really totally independent ("harsh" as you say) use exponential.

[latent latch]

probably can just use an animation curve honestly

[unkempt swallow]

exactly

[heady iris]

that's a pretty good idea, actually

just make a curve that looks good

[polar marten]

no guys

it doesn't work that way

[chilly surge]

I've already given the answer here.

[small linden]

I'm having issues with my PropertyDrawers not actually binding the values of a PopupField in the inspector. What's the most appropriate way to share the code I've got so far without flashbanging the channel?

[polar marten]

if he draws that curve, no matter which direction, it doesn't solve th eproblem

just use exponential. you have 1 parameter

see if it feels good

"lambda" is the "rate" (higher means bigger values are more rare)

[vestal arch]

uhh i think you mightve misread what mao said

[polar marten]

to turn it into kg, you can do min(1, floor(exponential(some rate)) + 1, 100)

but. @unkempt swallow . you should model this as a deck you draw from. it will be more fun

[chilly surge]

The solution I've given literally works for any curve, they can change the curve however they like until it feels good.

[polar marten]

you can also refill the deck after you draw if you want it to be "harsh"

[vestal arch]

i think with the lack of confidence in math kinami has, the animation curve would be a viable option

[polar marten]

the curve doesn't mean what you think it means

[unkempt swallow]

im checking all solutions offered, rn using the linked github repo and the radnomexpo, but the values are 1.004811 like, nothing above 1

[vestal arch]

not a distribution curve or a probability curve

[polar marten]

okay. what do you want the average value to be?

like most of the time

[small linden]

Is there a more appropriate place to ask this?

[unkempt swallow]

randomly chosen between 1-20% of the max value

[polar marten]

the one that you should "expect" to get
rate = 1 / expectation

[hexed pecan]

#↕️┃editor-extensions

[polar marten]

you aren't expressing htis quite right. the expectation is 20kg? 10kg? etc.

so 10kg?

so the rate you want is 1/10.0

[unkempt swallow]

no i dont want one specific value , it has to be random like i said, i dont want to define anything solid

if i wanted that i could have hard coded it by now xd

[vestal arch]

do you know what a mean is

[unkempt swallow]

no

[polar marten]

okay well

[unkempt swallow]

was my picture not good enough

[polar marten]

haha

[vestal arch]

if you fished 100 times, what should the average be

[polar marten]

i think you are learning it's okay

[vestal arch]

(pretty sure an animation curve would mean exactly what it seems like)

[polar marten]

🥺

[vestal arch]

that isn't in the realm of statistics anymore

[unkempt swallow]

side question

https://en.wikipedia.org/wiki/Exponential_distribution are you supposed to learn this in school?

[vestal arch]

depends, really
