I mean there are signs for the spoken words, maybe they use the arabic numerals when not explicitly writing it like "1" vs "one"

Create a static "Tags" class or an enum and put all your Tags in there, if you end up changing one you just change the string in that one and not 15 places in the Code

[lone zealot]

Any idea for the localized int->string problem? For example, in English a 3 would be "3", but in Arabic it will be ۳. I'm sure Unity's localization has an easy way of achieving this but I can't find anything except for the inconvenient solution I showed earlier

[dusky lake]

Cast to string, have translations for the strings

[chilly surge]

That only helps within code, which can still get out of sync with your tags in editor.

[dusky lake]

Yes it can but its miles better than having your code littered with magic strings

As for inspector, once I am home I can look for the custom inspector I found some months ago that actually gives you a dropdown, still doesnt help you when changing a Tag though

[wide terrace]

Just don't use tags 😁

[chilly surge]

Yes, the conventional wisdom is that instead of trying to use all the tricks to make a fundamentally flawed feature less flawed, it might be better off to just use something different.

[lone zealot]

Will need a CultureInfo for that. Couldn't find any API in the localization system that gives us that, according to our currently selected locale

Int to string should be a very trivial task for a localization system, I don't know why Unity's makes it hard (or maybe i just haven't found the easy way yet)

for new readers, i mean a 3 to "3" or "۳" depending on the locale. A 1500.5 to "1,500.5" or "۱،۵۰۰/۵"

[dusky lake]

Oh you even want decimal conversion and stuff, well I guess someone will have had that problem in the past and you should crawl github for C# solutions. This one sounds like such a general problem that there has to be a solution

https://stackoverflow.com/a/47323966

And
https://learn.microsoft.com/en-us/dotnet/api/system.globalization.regioninfo.currentregion?view=net-8.0

Or I guess unity has other ways to get a country code

I'm trying to implement a "shelf" system where items will be instantiated onto set positions. I'm having trouble figuring out how to account for different rotations. Any ideas on how I could make this work on more than just one axis?

[wide terrace]

Seems like you just need to instantiate them with the shelf's rotation, no?

or maybe rather their container object? 🤔

[brave mica]

When I do that this is the result. I'm no good at the math aspects but it seems like the problem is in the position rather than the rotation. Like I want to find the position using the rotation of the container but not sure how

[wide terrace]

Ah sure... What's the code look like?

[brave mica]

boundsX/Z --- The minimum bounds of the BoxCollider of the container
capacityX/Z --- The total number of items that can fit in the shelf X/Z axis (This is calculated in another method but is working as intended)
paddingX/Z --- The padding between each item
itemSizeX/Z --- The unit size of the item on the shelf

float posX = boundsX + (itemCount / capacityZ * itemSizeX)+(itemCount / capacityZ * paddingX) + (itemSizeX/2) + paddingX;
float posZ = boundsZ + (itemCount % capacityZ * itemSizeZ)+(itemCount % capacityZ * paddingZ) + (itemSizeZ/2) + paddingZ;
Vector3 pos = new Vector3(posX, containerHeights, posZ);
GameObject go = Instantiate(items.gameObject, pos, transform.rotation, transform);

It's sloppy so lmk if there are any confusing bits 😅

[mild quail]

is there a way to have 2 event systems with completely separate gameobjects that are interactable? I have 2 event systems in my game that I'm toggling between but it's possible to select the old things still when the new event system is active since the new event system is letting the user interact with the other gameobjects

[wide terrace]

So I think the issue is that that code works entirely in world space, so when you position the item relative to the boundsX/boundsZ offsets, it does so on the global axes.

I think the solution might be to run your local positions through like transform.TransformPoint() before adding the bounds in, so maybe like...

Ah wait... bounds is already local. I am very rusty 👀

[wide terrace]

Try

Instantiate(items.gameObject, transform.TransformPoint(pos), transform.rotation, transform)

[brave mica]

That is looking better, I just need to modify the code to find the position which shouldn't be too bad. I'll tinker around and respond, thanks for the lead

[wide terrace]

Yeah, sorry it wasn't terribly accurate 😅

Double check that the bounds variables are in local space!

[delicate zinc]

I am incredibly confused by an issue i'm having on this script.

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

I got this script, on Awake i'm getting characterBody and storing it in a Property, however, if i use the ToggleCombat context menu, it throws a null reference exception on line 20.

What could cause the property to null itself for apparently no reason? using cross referencing shows that the only two things interacting with the proeprty is the setting of the value and the method call

Awake is getting called according to me breakpoint debugging, but if i put a breakpoint on the property itself nothing happens (the breakpoint isnt getting hit)

[weak spruce]

how to fix that

using System.Collections;
using UnityEngine;
using UnityEngine.UIElements;

public class SheepController : MonoBehaviour
{
    public Transform Dog;
    private float speed = 3f;
    private float distance = 2.5f;
    private Animator animator;
    public LayerMask hitlayer;

    void Update()
    {
        Vector3 origin = transform.position;
        Vector3 Direction = Dog.transform.position - origin;
        Dog = GameObject.FindGameObjectWithTag("Dog").GetComponent<Transform>();
        animator = GetComponent<Animator>();

        RaycastHit hit;

        if (Physics.Raycast(origin, Direction, out hit, distance, hitlayer))
        {
            animator.Play("Run");
            Quaternion targetRotation = Quaternion.LookRotation(-Direction);
            transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * 100);
            transform.Translate(-Direction * speed * Time.deltaTime, Space.World);
        }
    }
}

[leaden ice]

characterBody = GetComponent<CharacterBody>();```
GetComponent could return null if such a component doesn't exist
or
`ToggleCombat()` could be getting called before Awake runs (or perhaps Awake never runs if you're calling it on a prefab or something)

Can you show the full stack trace of your error?

[leaden ice]

how to fix what?

[weak spruce]

fix sheep jumping out of the map

[leaden ice]

Move your sheep via physics instead of blindly teleporting it via the Transform.

btw .GetComponent<Transform>(); is never necessary, you can just do .transform

[delicate zinc]

hold up i think i fixed it?

[weak spruce]

how to move via physics

[leaden ice]

With a Rigidbody

[delicate zinc]

ok, i think i was indeed calling it on a prefab accidentally .

oops

[mossy oyster]

Hi, I've got a question, I have a game with levels and I have an editor inside the unity editor to make them but I don't know where to save them (I don't want/can't save them in different scenes etc...). I want to save them in a json (it's actually just some lists of points), problem is idk how to create a json file inside of the assets folder neither how to access it (the path), how do I do that? Or is there a better way than json to save lists of vector2D/bools/int

[brave mica]

Ok ive almost got it but cannot figure out how to get the unrotated bounds on the BoxCollider

[wide terrace]

Ahhh right. Hmm hmm... Are boundsX/Z just calculated from like collider.center - collider.size / 2?

or collider.bounds.min?

[brave mica]

the latter

[knotty sun]

I know this might be a bit simplistic thinking but if you are having problems placing objects onto the rotated shelf why not unrotate it, place the objects then rotate it back

[wide terrace]

Okay, so I think they are in world space. If you can switch to the former I believe it should just work. Otherwise you'll need to add them to the position after it's transform.TransformPoint()'d rather than before

[brave mica]

Mission successful, cheers for the help

[proven scroll]

So im trying to make a puzzle game where you collect words in the world and once you collect them they go to the "TV' (the place where they will put the puzzle together, which is all in the same scene) once they are in the tv they cans be collected anymore and you are able to drag them around and put the words in specific points on the TV if it is the correct point it will stay if not it will return to the original place inside the TV

What would be the best way to go about this as there will be many different words

[rigid island]

what is the specific issue you're having, there are dozens of ways to do this

[proven scroll]

Okay So i made a scriptable object that i can reuse to have diferent words, and for testing i have 2 different words in my scene and when i collide with one they both get triggerd even though i didnt touch the other one

and was wondering how the best way to go about this structure wise im just getting so confused and turned around on how to get this going :/

[vivid wind]

Are nuget packages available through the unity package manager? I'm considering converting my external utility library to a package, but I have some dependencies such as DependencyInjection and abstractions, and a few others. The information I've found on the topic is mixed at best. AI seems to thinks it possible, but found a 2020 post that says nuget packages arn't supported.

[lone zealot]

Nuget isn't supported officially, but you can download the DLLs and import them yourself

[pliant spade]

Hi, Anyone knows how to set the {Level} variable of a smart string from a script?

[hidden flicker]

Is there a way to get the normal of a face just from OverlapSphere?

[lone zealot]

Add a local variable in the inspector (bottom of this screenshot), then do stringReference["Level"].value = value

[pliant spade]

what do you mean by stringReference["Level"].value = value ? from the LocalizedString component?

[spring creek]

Looks like no. A workaround is that you shoot a raycast at the colliders returned by overlap

[lone zealot]

Yes

[keen lantern]

Hey, I am receiving this weird problem when Im trying to instantiate an object. It does instantiate in the scene, but the object tends to be disabled in the scene when it instantiates. Any reason to why this might be?
Heres the instantiation line of code if needed: equippedItem = Instantiate(selectedItem.heldItem, playerHand);

the heldItem is a GameObject btw

[pliant spade]

Well it does not exist, neither from LocalizedString or LocalizeStringEvent

[rigid island]

Start simple, by that I mean shrink your original object. Look into triggers and how they work, etc.

[lone zealot]

It does. Look for StringReference

[keen lantern]

oh and yes, the prefab for it is active as well.

So I simply dont really understand how its instantiating as inactive

Oh apparently something about the network object is causing the problem

I shouldve know that stupid multiplayer is the issue here

[pliant spade]

m_localizeStringEvent.StringReference["Level"] = new IntVariable { Value = 10 };

This did the trick

[lone zealot]

Instead of creating a new IntVariable, you can directly set the .Value

Because it's mutable

[pliant spade]

Not accessible, unfortunately

[lone zealot]

IntVariable iv = m_localizeStringEvent.StringReference["Level"] as IntVariable;
iv.Value = 10;

[pliant spade]

Yea I get it.

Thank you!

[fiery blaze]

anybody maybe know why this isnt working?

[wide terrace]

What does the error say?

[wide terrace]

Is ab a Rigidbody2D?

[fiery blaze]

no 3d

[wide terrace]

Check out the docs - the error is accurate, there's no way to call it with three arguments

[fiery blaze]

oh wait

im dumb

i meant to use rigidbody smh

[spring creek]

Using a rigidbody would still cause the error. You are passing three random numbers in

You should pass in the Vector it is expecting

[fiery blaze]

it seemed to be fine

command worked

[spring creek]

You're right. I always forget that it has that second overload. ArticulatedBody does not though haha.

[fiery blaze]

yeah i just seemed to figured it out Loll

[coral phoenix]

Hi, I'm having some problems with the DontDestroyOnLoad objects, i'm trying to get the component "Unit" that is in: party -> Teammate1 -> Unit, but when I assign it, it doesn't refer to the actual object, I think it is creating a new "unit" component to reference

https://pastebin.com/svcBNAK8

i think the problem is in line 20-24, but I can't find a way to fix it

[vale wharf]

Trying to get a bone (selected) to face towards player. However, due to the fact the bone has a weird axis layout (Y is forwards), I am having difficulty trying to get the code to work.

var playerDerivative = (PlayerController.instance.transform.position - headTransform.Value.position).normalized;
var rot = Quaternion.LookRotation(playerDerivative, Vector3.forward); //Since Z is up for the bone.


headTransform.Value.rotation = rot;

Am I doing anything wrong?

[fervent coyote]

Hey there, I'm wanting to implement a way for the player to add custom scripts to weapons, so when they attach the script to the ScriptableObject's variable, instead of running on built-in code it'll instead run the custom code, however, The code WILL have to be static (Although I could always just make the script attach to the player and then remove itself when switching weapons), and I know that you can't use the monobehaviour itself in the code, as you have to future proof for pretty much every class name. Anyway I can do this?

[cold parrot]

You want your players to write custom scripts?

[fervent coyote]

If they so wish, yes, specifically for weapons.
You know how the Source engine has specific scripts for weapons? Such as physcannon (Gravity Gun), something like that, although I'm hoping for a way to be able to reference the script as a variable, and either it'll add the component to the player/npc when it is equipped, or will call static functions

It would work like:
(In the ScriptableObject)
public Script Weapon_CustomScript = null; (I know that Script is nonsense, just psuedocode)
(Custom Script)

{
    public static void Weapon_PrimaryFire(GameObject origin)
    {
        Handler_Gamehandler.Game_GetGamehandler().Astro_WriteToConsole(origin.name + " Primary Fire");
    }
    public static void Weapon_SecondaryFire(GameObject origin)
    {
        Handler_Gamehandler.Game_GetGamehandler().Astro_WriteToConsole(origin.name + " Secondary Fire");
    }
}```
When the player runs the primary or secondary fire, it would call the function, regardless of class name

[cold parrot]

Anyway, if that’s what you want you should embed an interpreted scripting language with a limited and well curated API for game functionality it can use.

Stuff like that is often done with Lua.

[fervent coyote]

Ah, I see
Is there a way to have a variable be set to a script? I can't seem to find it, and I'm not sure if it's a niche thing or not

[cold parrot]

Very niche

Technically you can allow a player to call any method on any GameObjects that is loaded in the game via SendMessage()

[fervent coyote]

Oh, I'm well aware, although some people have said that is a very bad idea

I'm more or less concerned how I can get a script to be a variable, so I can put the script unto the player/npc

[cold parrot]

it is

[prime moat]

Guys i have a quick wuestion, im making a tank game and im going to start working on the tech tree now, basically like the one in warthunder in which you can unlock tanks etc. I was wondering if this should be done with normal script or is it better if i do it with ScriptableObject

[cold parrot]

you can't store a script in a variable, but you can add a component to a gameobject through specifying the class (type). and you can store that type in a variable.

[lean sail]

Either one works, but it's really just a matter of do you want to assign these in editor (with scriptable object or monobehaviour) or by code (plain c# class).
For something like a skill tree, I cant imagine you'd need to be serializing much

[cold parrot]

technically you could compile a script from source at runtime, load that and run it, but idk how unity responds to that kind of thing. In any case its not a good idea.

[prime moat]

Alright, thanks :))

[fervent coyote]

Well, that wouldn't fit what I would be looking for, unfortunately...
I was hoping that it would be as easy as assigning a variable to the variable, and that static functions would be called

[cosmic rain]

If you're referring to the interpreted script that the player wrote, in the worst case you can just pass the code string. Or, better, a reference to an object that contains the code string.

[fervent coyote]

Yes, the custom made script is what I'm reffering too

[vale wharf]

Anyone able to help?

[cold parrot]

i'd say if you can't embed/build a separate runtime for that kind of thing (lisp, lua, custom DSL etc.) drop the idea

[fervent coyote]

I found MonoScript, but there doesn't seem to be a way to actually call functions from it

[cold parrot]

you have to build that hook for function calls yourself. You can use C#'s reflection features to access/call pretty much anything

[cosmic rain]

Might be easier to reexport the model correctly, or use a proxy empty go to fix the rotation.

Ah, it's a bone... A proxy wouldn't work then.

[fervent coyote]

Ah, I see

[cosmic rain]

You can't just use C# code they wrote as is, you'll need to compile it. That's why Anikki suggested a different interpreted language for it.

[wide terrace]

Also players exchanging C# scripts with access to native libraries is terrifying 😬

[fervent coyote]

I think I may be a little dum in the head, sorry 😓
I also didn't think of the ramifications of that, either

I just want players to easily mod my game, if they so desire too

But I'm not really sure to implement LUA or other DSL languages

[cold parrot]

unsupported but might get you some orientation: https://assetstore.unity.com/packages/tools/moonsharp-33776

[cosmic rain]

Honestly, this kind of feature is something stretching to the advanced level. And even if you have long years of experience with unity and coding, it would require a thorough research. Not something you can just get an answer lightly on discord.

[fervent coyote]

I was hoping it would, but thank you for your help regardless

I'm also... intermediate, to be honest

Although, I DO have addons working (Loading scenes/maps, ScriptableObjects, etc), just custom scripts would be awesome you know?

[cold parrot]

its awesome but also extremely powerful, hence the complications

[cosmic rain]

It's not impossible, you just need to do proper research.

[cold parrot]

if unity were written in python or javascript this kind of thing would be trivial, but you'd also have only 1% of the performance

[rustic rain]

can you serialise with a different number than the actual property?

[cold parrot]

that makes no sense

[rustic rain]

sorry i meant different name

F transform looks ugly

[cold parrot]

depening on your serializer your can

[rustic rain]

i want to just be transform

im using odin

[cold parrot]

you can put a custom label on anything with odin

doesn't change the serialization though

https://odininspector.com/attributes/label-text-attribute

[cold parrot]

this is a bad name btw, you should generally spell out what a thing is, not abbreviate, this then fixes the uglyness too.

[lean sail]

people know how to mod enough that you dont have to do anything special. You could just make it easy to attach new scripts and leave a general tutorial on how you created the weapon objects.

People will probably mod it faster than you can make logic for them to mod it with

[fervent coyote]

Yeah, alright, thank you!
As an example, each weapon is a ScriptableObject called ScriptObject_Weapon

[cold parrot]

also worth considering that unity is in no way designed to be a framework for making another game-engine or any kind of application that deals with data ingress. You can build all that yourself, but you get no help from unity. Those who tried (that i'm aware of) have abandoned the approach in their v2 if they have survived. Mod "support" extends only to assets, configuration and interpreted scripts (if you provide the runtime for them).

[vale wharf]

I don't know how. Every guide on "exporting models for blender" tells me to keep bone axis settings the same.

afaik I am exporting this model correctly.

[cosmic rain]

Hmm... Well one thing you could do, is get the required rotation first and then rotate your bone by that rotation, instead of using look rotation.

[cosmic rain]

Like, the issue is that you need to know the offset of the bone to do any correct rotation taking the offset into account.
If you know that it's up is actually forward, then you could just do transform.up = direction instead of messing with quaternions.

[lean sail]

is that screenshot after your code has ran? or is that how it looks in the prefab?
If it is an issue with the model try stuff written here. This person helped me i never had an issue exporting after #🔀┃art-asset-workflow message
It could even be that the model/rigging wasnt setup correctly

[fervent coyote]

Hey, so, how can I rename a class without losing the variables located within?
For example, I hate that my current class is called Entity_Transition, and want to change the #C script and class to Entity_EventChangeMap

However, I am worried (Because I have done this before) that when I do, I'll lose a lot of progress cause I use this a lot, can anyone help me out here?

[rigid island]

F2

you wont lose the vars but might reset the values. I dont remember lol

[fervent coyote]

Oh, I meant the values on a gameobject

[dusk apex]

Git backup your project. Take a picture of your settings before modification or write a script to save/load your scene settings.

[lean sail]

i dont think ive ever lost values when i renamed a script. Thats even when I rename it entirely in visual studio, while apparently you're supposed to rename it first in unity

but yea not like anything can go wrong if you use version control

[fervent coyote]

I use Github GIT

[rigid island]

do note the two are not related

github just hosts GIT repositories

but there are others, bitbucket, gitlab etc..

[wide terrace]

If I wanted to store instances of distinct classes which share a common interface, key them by type, and expose an API similar to GetComponent<T>(), would this be a remotely reasonable means to accomplish it?

private Dictionary<System.Type, SystemController> _systems = new();

public void AddSystem<T>(T system) where T : SystemController {
    _systems.Add(typeof(T), system);
}

public T GetSystem<T>() where T : SystemController {
    if (_systems.TryGetValue(typeof(T), out SystemController system))
        return (T)system;

    return null;
}

I guess they don't necessarily need to be keyed by type - I just found myself reaching for something akin to a JavaScript Symbol

[chilly surge]

What does JS symbol do in this use case? JS symbol is essentially just a pointer that can be used as property key, I don't see how that's related.

[wide terrace]

Probably only through my own ineptitude and unfamiliarity with generics 😁

Maybe more succinctly: I want to store distinct instances of the classes, and did not want to index them via some member on the instances which might only exist for the purpose of indexing them. So indexing them by type seemed to make a lot of sense in my head

I just mildly fear I stumbled into some poor pattern or implementation. This is me mostly just flailing around a bit

[chilly surge]

Yeah I just don't see how that's related to JS symbols, but otherwise that code seems fine.

[wide terrace]

Thank you I appreciate it!

[chilly surge]

JS symbol really just is a reference type, so if you want something like one, it's just new object().

[wide terrace]

Ahhh that's interesting. Sure, that makes sense

[chilly surge]

JS symbol is the same too, you could just do const myKey = {} and that guarantees uniqueness. The only reason JS symbol has to be invented is because you can't use that as a key (so you can't do dict[myKey] = 42)

[broken light]

is unity's mesh RecalculateNormals() method on github? need to see how they calculate it since mine isn't correct

[wide terrace]

You are totally right. I don't touch symbols often - but I was playing with them for work earlier today and I think they're maybe still haunting my brain and winding up in places they shouldn't be. You are right - a Symbol has no relevance here 👍

[spare island]

I have a bit more of an abstract problem, but I'm trying to figure out how I should structure my combat in my code.

So I have an actor who has the ability to attack with either their fist or with a weapon, and there are different types of weapons with different animations, combos, etc. What is responsible for doing the damage? The sword object itself, a combat script, the receiving party.. etc

it's very confusing

I'm looking not for a direct answer for this exact question but maybe some pattern/design solution commonly used for this problem

and there is such json

{
  "Statuses": [

I'm trying to convert this json into an object via

but an error occurs on the device

 ExecutionEngineException: Attempting to call method 'System.Collections.Generic.List1[[RelationshipStatusConfigData, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]]::.cctor' for which no ahead of time (AOT) code was generated.

could this be due to the fact that there is an array of RelationshipStatusConfigData and not a list?

[knotty sun]

Yes, that confused me. In json there is no difference between an array and a list so I'm somewhat confused why it is trying to build a list

[nocturne wyvern]

why can this happen at all? Literally in another branch everything worked with an array

[knotty sun]

I have no idea, I dont do json but your code and data look fine.
one thing you could try is to initialize the array so it is not null

I am presuming this is Newtonsoft Json

[nocturne wyvern]

yes

[knotty sun]

I know why it is throwing the error but I have no idea how it gets that far. The easy fix would be to change the array to a list but that should not be necessary

[nocturne wyvern]

I found this solution, but I still don’t understand what this is connected with, I’ll try it

It might be worth updating the version of Unity or the version of newtonsoft itself

[knotty sun]

yeah it is the=managed code stripping.
simply adding a List<RelationshipStatusConfigData> somewhere will solve it.
I'm guessing JsonConvert first builds a list then converts the List to an array which would make sense because it cannot know the size of the array whilst it is parsing the data file

https://docs.unity3d.com/ScriptReference/Scripting.PreserveAttribute.html

[nocturne wyvern]

is it enough to add it above my array?

[knotty sun]

tbh I would add this to your RelationshipConfigData struct

[Preserve]
static List<RelationshipStatusConfigData> ToList() { return new List<RelationshipStatusConfigData>(); }

[nocturne wyvern]

where should I call this?

[knotty sun]

you don't that is the whole point

[nocturne wyvern]

in one of the projects I also used such a thing

[knotty sun]

just by having the code with preserve will ensure the the List<RelationshipStatusConfigData> constructor will exist at runtime

[knotty sun]

sorry that code should be RelationshipStatusConfigData

[nocturne wyvern]

i will try to use this

[knotty sun]

you still need the [Preserve] attribute

[nocturne wyvern]

this is all?

[knotty sun]

yep

[warm badger]

can i set custom frustum culling range in Graphics.Drawmesh function?? I want to render a lot of grass inside a custom range...but not inside the whole frustum range of the camera..what should i do?

[maiden fractal]

Well, I don't think you should call Graphics.DrawMesh for each grass mesh individually, instead you should call one of the instanced methods to do it much faster

[warm badger]

i couldn't get it... can you explain a bit?

[maiden fractal]

Each time you call Graphics.DrawMesh, it's basically a draw call which are quite slow if you call it thousands of times. Instead you should pack your data to ComputeBuffers/Textures and render all the grass at once with Graphics.DrawMeshInstancedIndirect or similar method. It's bit harder to set up but it's definitely worth the time to drastically improve the performance. The problem with the instanced methods is that they don't do any frustum culling at all which takes us back to the original question. Since there's no frustum culling happening by unity, you must implement the frustum culling yourself and therefore you can do your own range stuff there.

[warm badger]

do you have any idea on how to do that custom frustum culling thing??

[maiden fractal]

You basically must take all your grass positions and put them in a ComputeBuffer and use Compute Shader to produce a list of grass positions to render. I assume you are trying to create grass system that's able to draw thousands and thousands of grass meshes am I right?

[warm badger]

yeah! i want to render a lot of grass meshes

[maiden fractal]

Then Graphics.DrawMesh won't work as I said. There's also a lot of raedy to use grass systems available if you don't have the time and effort to put in one

[warm badger]

yeah...looks like a long way to go...

[vale bridge]

I read online that says that unity uses the Mono C# compiler, produces Bytecode(IL + metadata) then uses the Mono Runtime to translate that into the platform specific Machine Code

[knotty sun]

correct

[vale bridge]

And the reason why unity is able to export cross platform is because of Mono's role in the above sentence?

[knotty sun]

indeed

[vale bridge]

I'm also confused on if the compiler for the C# scripts matter in terms of cross platform ability

if we have two different compilers and then feed the bytecode into mono runtime will they both be able to be translated into platform specific machine code?

[vale bridge]

The blog post I read said that unity uses Mono C# compiler for the scripts, but I was wondering if this was necessary

[knotty sun]

yes it does because Mono .Net IL is not the same as MS .Net IL so if you compiled using MS .Net (at least for the versions Unity uses) it may cause problems cross platform

[vale bridge]

I see

Is it because Mono .Net libraries(I'm under the impression that .Net is a giant conglomerate of libraries) might be diifferent to MS.Net libraries?

[knotty sun]

exactly

[vale bridge]

So then is the reason mono developed because MS.net didn't have cross platform in mind so they decided to translate that functionality so to speak themselves?

Do the two follow some sort of agreed upon guideline so the .net base functionalities are somewhat similar, or do they now do their own things but develop under the same ".net" name

[knotty sun]

that is basically correct, then MS reabsorbed Mono and renamed it Xamarin To bring some kind of normalization but there are still many differences. When (if) Unity eventually migrate to .Net 7 + then all of this should go away

[vale bridge]

TIL Xamarin and Mono are the same thing

[vale bridge]

I've also read about this IL2CPP that supposedly came around 2018 and I was wondeirng if it ran on the same .net libraries that Mono provided, or is this another rewrite situation?

Oh nvm it stands for intermediate language to Cpp

Does that mean instead of mono runtime it uses IL2CPP instead, but still uses mono libraries during compilation?

[knotty sun]

IL2CPP does exactly what it says, It convers IL into C++ source and then compiles it into native binary, this means that it is not cross pllatform

[vale bridge]

This means that IL2CPP compiles into native library ahead of time(AOT)? And that this only works on select platforms

[knotty sun]

exactly

[vale bridge]

So if I'm gettin gthis correctly, IL2CPP only works on platforms that CPP is able to compile into native binary

or rather platforms that use native binary

[cosmic rain]

That's basically any platform out there

[knotty sun]

which will be all platforms, the important thing is that code compiled for one platform will not run on a different one

[cosmic rain]

Everything runs on C++ or C

[vale bridge]

Ahhh I see

[vale bridge]

I had no idea

[cosmic rain]

To be precise, C/C++ compiles to almost any platform native code

[knotty sun]

yes, to be more precise, platform specific native code, which is why it cannot be cross-platform

[vale bridge]

Ah that makes much more sense

I did a little reading just now and my interpretation of the mono vs il2cpp is as follows:

1. Mono is cross platform because it translates into machine code on the fly from ByteCode(JIT)
2. IL2CPP is ahead of itme compileation which because native machine code is different, is not cross platform, but since CPP can target any native machine code you can export to any platform

Which makes me wonder if cross-platform means strictly that you can run the smae piece of code on different platforms

[cosmic rain]

To be fair, "not cross-platform" doesn't really matter here. It's not like you can run a mono build for a specific platform on any other platform.

[vale bridge]

That's what I was wondering as well

[knotty sun]

This 'you can export to any platform' is the wrong concept. you do not 'export' you 'build to'

[vale bridge]

As in building to a specific platform's native code?

[knotty sun]

yes

[cosmic rain]

Mono and dotnet are cross-platform as frameworks. Meaning that their API is able to be compiled to any supported platform and is usually guaranteed to work the same way. On the other hand, if you're building a C++ app, there would be a lot of platform specific code, platform specific libraries, etc...

[vale bridge]

Gotcha

[cosmic rain]

Unity takes care of that for you regardless of whether you build a mono or il2cpp, although there are some limitations

[vale bridge]

I'll look into what exeactly this platform specificness is... my confusion comes from the fact that different platforms have different native languages and that handling conversion from high level languages to this native language would have to be handled anyways regardless of cpp or mono?

[vale bridge]

I've read that ios supposedly does not support JIT so mono can't be used or something

[knotty sun]

If you look at the workflows it's quite simple
Source->.Net Compiler->IL->.Net Runtime->OS->bare metal
or
Source->C++ compiler->native binary->OS->bare metal

[cosmic rain]

Platforms don't have native languages. It's more correct to say that they have their own CPU instructions. When you compile a C++ build to native language it means constructing these instructions. Same when dotnet is compiling JIT.

[knotty sun]

IOS has XCode which, basically functions the same way

[vale bridge]

So in IL2CPP's case would it be
Source -> compiler -> IL ->(via il2cpp) C++ source -> native bin
or is this a wrong interpretation

[knotty sun]

that is correct

[vale bridge]

build to = translate to target instruction set commands?

[cosmic rain]

Yes. Basically.

[warm badger]

is it possible to make Graphics.DrawMeshIntanced objects support lightprobes by any means?

[knotty sun]

not happy with the word translate because a compiler does a great deal more than that

[cosmic rain]

I guess if you can bind the required data/resources manually and your shader uses it correctly.

[vale bridge]

would this be a good time to read up on compilers then?

Any uhh recommended sources for this type of stuff

[cosmic rain]

If you're interested. I wouldn't say it's absolutely necessary for a gamedev.

If anything, I'd rather stay a way from low level stuff and let smarter people deal with it

[knotty sun]

I honsetly would not know, I grew up with stuff as it was being developed

[vale bridge]

Roger that

At least now I somewhat know how unity cross platform works

Thank you both for this incredibly long dicussion, I definitely understand this much more than I did before

Really appreciate it

[knotty sun]

thats not just Unity cross platform, the same basic structures are true for most modern languages like Java, JavaScript and Python

in fact C and C++ are somewhat on an anachronism as they compile to native code, not many modern languages do

[vale bridge]

is this a bad thing?

[knotty sun]

only in terms of performance, C and C++ will always out perform anything else

[vale bridge]

Gotcha

[knotty sun]

the closer you are to the metal, the faster the code will run, this is why we still write device drivers in assembly code

[vale bridge]

Thank you for the explanations

[rough sorrel]

Hi. One question, is it normal that using Invoke(nameof(DoSomething),0); is faster than doing DoSomething();? Like, what are the downsides of using Invoke then?

[quartz folio]

It's significantly slower

[knotty sun]

Invoke can never be faster than a direct method call

[rough sorrel]

then idk what I'm doing wrong with my setup but it is telling me that it is faster. Let me see if I can do it again and show it

[cosmic rain]

What kind of "setup" do you have?

And what's telling you that it's faster?

[rough sorrel]

The setup:

public class CodeTesting : MonoBehaviour
{
    public int iterations = 10000;
    
    [Button]
    public void Iterate()
    {
        for (int i = 0; i < iterations; i++)
        {
            Invoke(nameof(DoSomething),0);
            //DoSomething();
        }
        
    }

    public void DoSomething()
    {
        Debug.Log("smth");
    }
}

[rough sorrel]

profiler

[quartz folio]

That is never going to work as a test case to profile

the likely reason that there's a difference is because the stack has been thrown away when you use Invoke, so the overhead of extracting the stack for the log is lower

it's got absolutely nothing to do with how you're calling the method

[rough sorrel]

ohhhhh okay

I didn't know that. Then ignore what I said before. Thanks

[hushed cloud]

Why does my layer mask make this check box ignore all layers and not just layer 10? 😕

bool isColliding = Physics.CheckBox(boxCenterWS, wheelContactArea * 0.5f, wheelParent.rotation, 10);

[quartz folio]

https://unity.huh.how/physics-queries/layer-masks

[knotty sun]

because layer 10 is NOT LayerMask 10

[dusk apex]

The bit shift solution - although you should just have a field and set the layer from the inspector 1 << 10

[hushed cloud]

I did try GetMask and NameToLayer without much success earlier

1 << 10
This did the trick though

[dusk apex]

Create a field:cs [SerializeField] LayerMask layerToIgnore;//Set the layer from the inspector.Apply/use the value:cs bool isColliding = Physics.CheckBox(boxCenterWS, wheelContactArea * 0.5f, wheelParent.rotation, layerToIgnore);

[quartz folio]

As my link says, NameToLayer would also be invalid

[midnight coral]

Hey does anyone know how to stop 2dynamic rb2d from pushin each other

[dusk apex]

What should they do instead?

[midnight coral]

act like walls

so when walking into each other they both stop the other

while not being pushed backwards

[dusk apex]

Sounds like you'll have to implement some custom edge cases for non static colliders not wanting to treat each other as dynamic objects - modifying drag could probably yield the behavior you'd want but might create other unwanted issues.

[midnight coral]

for example?

[spare island]

Might have to do something like raycasting towards it and then manually negating the velocity

So if touching other dynamic body:
Velocity = 0, current, 0

[midnight coral]

This can work but after touching a body they stay inside each other meaning that the velocity gets set to 0 only once at the beginning of the collision afterwards the player can continue to try to move inside the enemies collider which will in turn push the enemy, i dont know if this is what will actually happen though

[spare island]

what about negative velocity where it pushes them away from eachother?

[midnight coral]

what i mean is that lets say theres an enemy staying still the player can run into the enemy the enemies velocity will be the sames as the players( same direction) the player will stop moving after hitting the enemy the enemy wont get pushed since we set the velocity to 0 at the start of the collision afterwards the player can decide to move again and this will push the enemy, if i make it so if the enemy checks constantly if a collision is happening so i can set the velocity 0 this will make the enemy not get pushed even after the player moves again after the initial collision but the enemy wont be able to move itself out unless the player moves out of the collision as the velocity is being set to 0 constantly

[spare island]

would it work to just make them heavier?

[midnight coral]

ive tried it

it doesnt help

[spare island]

Increasing drag?

[midnight coral]

the player might not push the enemy but the enemy can push the player and the enemy can push another enemy

[midnight coral]

yep

ive tried bounciness and friction to 0 as well

on the colliders

[lean sail]

Well all of those things are completely unrelated, so its not like itd do anything

Unless you set the velocity every fixedupdate to what you want for both objects, you cant really do what you want using unitys rigidbody.

[spare island]

this might be useful? https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131

its not an ideal solution ik

[midnight coral]

the game im trying to make is 2d

[spare island]

oh idk if it supports 2D

[midnight coral]

yeah this is why im stuck

the only thing that has kinda worked

is having enemies and the player have a child object with rigidbody2d set as kinematic with continues collision detection

[spare island]

do you actually need a dynamic rigidbody on the player

[midnight coral]

and having the collider of that child object bigger than the enemies or players collider

[midnight coral]

ive asked my self this question a lot xD

but yea i do

[spare island]

why exactly?

[lean sail]

You can just make your own kinematic rb solution for 2d. These other solutions wont work

You simply cannot have an active rb to achieve what you want. If you use it, it will be pushed around by other things with velocity, end of story

[midnight coral]

trying to make a 2d souls like and pushing the enemies or having no collision between enemies just feels wrong to me

i want it to be just like the games where the player can run into an enemy and nothing happens

or vice versa

[midnight coral]

yea

[spare island]

how about using a charactercontroller?

[midnight coral]

only is for 3d

doesnt work for 2d

[spare island]

is it?

[midnight coral]

yea if you have a 2d collider

it will say when trying to add it

[lean sail]

there are many tutorials out there for simple 2d movement

[midnight coral]

yea but all that ive seen are just no collision between enemies

or custom collision detection using a kinematic rb

thats what im thinking

of doing rn

[lean sail]

those tutorials would go through custom collision detection. of course theres no collision detection if you arent using unitys physics, which you cant in this case

But really you can just cast to check if anythings in the way, and not move into the object. If platforms/other stuff can move into your character, then you'd need to depentrate somehow

[midnight coral]

the not move into the object would work

but lets say i have a enemy that will lunge at the player

i need the enemy to have collision so that when it hits the player it stops

but is able to not be pushed

etc

[lean sail]

You can still check with physics casts to see if the enemy should stop during this lunge, and if you arent using a rb then it cant be pushed anyways

[midnight coral]

yea maybe

but thats the aproach im leaning towards the most

i just was trying to see if there is another way

thats simpler

[lean sail]

You could try what i said at the start, about setting the velocity every single fixed update to what you want. But im not sure if theres any catches with that

and it'll still do its own depenetration

[steady moat]

The player should definitely be kinematic.

Use Raycast/Boxcast to limit the movement.

[midnight coral]

what about the enemies

i need them to collider with other enemies and the player and not get pushed around or push others

would i need to raycast as well for them

[steady moat]

The same, if you do not want them to move when they are colliding.

[steady moat]

You can do all of them manually.

[midnight coral]

Thats what im trying to avoid xD

i was trying to see if theres a few options i can set and be done with it

xD

[steady moat]

Then buy an asset that does it.

[midnight coral]

I dont know if there is any

[lean sail]

honestly making your own 2d character controller should be fairly easy

3d is a different story

[steady moat]

You can always try to use multiple layer but I am not sure how it would behave

[midnight coral]

This is what ill probably will end up doing

[lean sail]

this is the same suggestion ive been saying most of the time, and same as what simferoce is saying

[spare island]

im 90% sure there are are already 2D character controllers available on github too

i'd be shocked if there was nothing available like what you want

[steady moat]

Usually, I like to only push enemies outward instead of preventing the collision

In other words, players/enemies/enemies does not interact

[midnight coral]

just opened to search xDDD

[south cairn]

I need advice, I'm making a card game and have cards stored as ScriptableObjects (CardSO) which have various effects also stored as ScriptableObjects (CardEffect).
And I want to have those effects to have their own little variables that can be affected on runtime by either their own effect or another card's, now currently I'm creating a separate MonoBehaviour script for every different effect (e.g.: the AddRequiredComponents in DamageTargets)
which can of course easily pile up a ton of different MonoBehaviours just for one card, and therein lies the problem.
How do I restructure this so that I don't have to instantiate a new MB for every effect without using ScriptableObject.CreateInstance() ?

[cold parrot]

experience of other people in this server with making a card-game (with arbitrary rules, not just poker) boil down to: it is very difficult to make the rules for these cards in a statically typed, compiled language and regardless of how you reach your goal, you will have created what basically amounts to a ill-conceived and badly maintained domain specific language. Their advice is it embrace that fact and just use an interpreted, lisp-/lua-like language from the start to represent your card-rules. for reference (never used these libraries) -> https://sharpscript.net/lisp/unity -> https://www.moonsharp.org/

reason being that declarative rules generally do not work out in the end and you will eventually want to add procedural code to them to keep things simple.

[south cairn]

I see, that's sort of what I expected. Though this is mostly a practice project for me to learn about SOs, so unfortunately I'll probably just go with a janky solution of putting all the 'effect variables' into the Card's MonoBehaviour.
Nonetheless thank you for your help

[hexed oak]

Have an SO that contains a list of all the effects you want on a particular item?

I think the advice "just use a different language" is an odd approach given this is a unity discord lol

But he presents a good point to the advantages of functional languages

Kinda reminds me of Greenspun's tenth rule

[south cairn]

yes I do have a list of CardEffect in the CardSO , so a list of ScriptableObjects inside of the ScriptableObject
the thing is I have some specific variables inside those CardEffect that I want changed on runtime, so I either need to use ScriptableObject.CreateInstance, make a MonoBehaviour with the same variables, or just move them to the Card's MonoBehaviour

[cold parrot]

the advice is not to use a different language its an advice about architecture and recognizing what the actual problem is one wants to solve. Its also not about "functional" languages but about a language where code is also data and can be manipulated while executing. Lisp in particular is excellent for situations where you have to dynamically invent a custom world in which to operate in while being extremely simple from a syntax/operator perspective.

[tardy hull]

Hey, does jobs and burst compiler work in browser games?

[dense rock]

Is there a way to make the screen darker besides a specific rectangle? I guess it should be something with UI mask maybe? I'm thinking about some inverted mask
or cut out a part of an UI image

[cold parrot]

Supported platforms
Burst is supporting the following platforms for standalone players:

Windows
UWP
MacOS
Linux
Switch
Xbox One
Xbox Series
PS4
PS5
Android
iOS

[tardy hull]

Thanks I couldn't find it in docs.

[steady moat]

You can use SerializedReference instead of MonoBehaviour. Also, I usually use the Factory Pattern for such situation.

public class DamageCardEffect : CardEffect
{
  public class Effect : CardEffect.Effect
  {
    //Actual runtime behaviour
  }

  public CardEffect Build() { ... }
}

public class CardDefinition 
{
  [SerializeReference]
  public List<CardEffect> effects;

  public Card Build()
  {
     foreach(CardEffect effect in effects)
       effect.Build();

     //Add other effect from other sources
     return card;
  }
}

[olive fractal]

Sorry if I misread your needs, but have you heard of the idea of Data Transfer Objects (DTO).
It is when you have a class that you acts as an intermediate layer as a go between for objects needing to read, write, move, or edit data.

In Unity some people use DTO with scriptable objects.
Example for an RPG that has crafting. The games items are scriptable objects and you want to have your players enchant weapons and save them, so you need to edit the item's properties of the scriptable object.

What some people do is they use a DTO that reads the initial values of the scriptable object and from there on in runtime edit the properties of the DTO.
So the DTO acts like the runtime data to edit, move, and do anything with.

[steady moat]

That would not be a DTO, but you explained what you mean correctly.

[olive fractal]

Well it is not exactly a DTO, but a false one. There would be more to it for it to be called an actual DTO.

In normal applications DTO are just used to encapsulate dara and transfer it between different systems or layers in the application.

In Unity you can sort of use a fake DTO like a struct, record, or a normal class that inherits from nothing.
You can think of the Scriptable Object as the layer of the game app that contains data like a database and use a fake DTO class that reads the values of a scriptable object and have other runtime classes used that fake DTO for example.

It is useful for the chain broker pattern.

[cold parrot]

it might be better to think of an SO as the immutable config state of a "thing" and that fake-DTO as its separate mutable state, whether that is bundled into a struct or represented as primitives in multiple lists would not change its nature, but if you call it a (fake)DTO, you force the whole story into OOP think which might actually be counter-productive.

[olive fractal]

That is 100% true as well. It really depends on how the structure of the scriptable object and the card effects are set up.

For his case I think what @cold parrot mention would be more relevant to my comment. Now that I read more of the previous conversation.

[cold parrot]

there sadly is just no way to do all this in a nice way.

in theory you can, it can be clean, you can make nice interfaces and algebraic types and higher order functions and all that, but its very impractical.

thats probably one of the reasons why so few card games get made that have non-pattern-based rules.

[olive fractal]

Honestly it might be a good idea to chart out the flow of how you want a pattern to work in game.
Than see what possibilities you need to work within a contained thought process for and go from there.

I found when working with systems that require a lot of extendibility, customization, and complex pieces doing something like this helps.
Do note this is a full on Metroidvania character controller for players, NPCs, and enemies so had to zoom in only on a piece of it because it is a chunky boy.

[cold parrot]

i would add that it makes development much easier if you have a map like this and know exactly what features you actually need. If you don't have such a map, you can easily get stuck in very generic implementations that produce no interesting gameplay. Generic systems also need way more code that does nothing and are way harder to maintain due to that.

[olive fractal]

Oh yeah, the amount of time I think our team saves by making maps way out paces the time it takes to make them. It gives us a chance to see where we may be overlapping systems or pieces of the project.
Allowing us to clean it up before we even start coding. This helps lower refactor possibilities mid development.

Something I think helps a lot of people out in team situations.

[cold parrot]

By now I firmly believe that without a ‘map’ you guarantee that the team goes nowhere and with a rigid map you guarantee that you will be building something useless.

[olive fractal]

Sad, but true words. When it comes to coding and making a map for things some people, including me I admit, might miss the mark sometimes.
Think at this point maps are meant as a way to help visualize the flow of intent for what you are coding and to be able to visualize different pieces that are connected to each other.
Including data being sent from one object to another or calling another objects function.

Maps might be a good thing to think of a guide on an always changing world. It helps get you near your destination and keep on track, but it should never be fully used as a concrete thing that can't be changed.
Through out development change is okay. The importance is learning how to set up code to allow for changes without breaking everything and having to refactor entire classes.
All hail interfaces and abstract implementations as long as they are not over used for that one.

[cold parrot]

The map also reminds you where you wanted to go, what choices you made and what forks are upcoming. Also allows you to track progress and keeps you moving.

the important thing is to realize where you are and where you can go from there. It’s so easy to dream about the ocean that you forget that right now you need most of all climbing gear.

[olive fractal]

What I read was mapping is a good objective tracker.
What my mind was thinking SCOPE CREEP SCOPE CREEP in your dreams.

[rotund burrow]

I want to make a jump pad. Normally i would write a script for a jumpPad object where OnTriggerEnter would push the player. However i'm not using a collider or rigidbody for the player (i do everything with raycasts). So how would i approach this issue? I was thinking attaching a trigger collider to player and calling OverlapBox on the jumpPad object.

[lean sail]

Is there a reason you arent using a collider/kinematic rb? If you do, you can still use physics functions

[rotund burrow]

I guess i could use a kinematic rigidbody. It wouldnt make much difference performance wise, right?

[lean sail]

we're talking about 1 kinematic rb and collider here

[rotund burrow]

i would have to do that for all units in the game in the future

[lean sail]

Then for that youd need to profile, comparing rb and colliders to an overlap check for every interaction that can happen with the units. Itd still be 1 overlap check per unit per fixed update

But honestly if your game lags from just kinematic rb and colliders alone, you're probably doing too much

[frail dust]

Hey everyone, I am an intermediate unity developer. Made two 2D Games for Android on my own. Also I have made one 3D game by following a tutorial.

I really want to understand how do I proceed further in my game dev journey? Specifically like shall I watch more tutorials , or learn more about C#, or just start making my own original projects (clones as well) without any help?

I just need a little guidance or a basic roadmap so I pave the way properly

[leaden ice]

Make a simple project on your own

Seek help as you run into problems

[frail dust]

Should that be a prototype showing mechanics or a proper game

Also Shall I just stop watching whole long hour tutorials? because I really think that tutorials have wasted my time. Not that those videos were bad, but How I utilised them were pretty dependent

[lean sail]

This isnt really something anyone can answer. Make what you want or need to. Do you need to showcase mechanics?

You definitely shouldnt be watching step by step tutorials that make a super specific feature. Most of the time you'll have trouble actually expanding on it. These are the tutorials where they type code on screen in real time.
Generally you should be looking up how to do a concept and try implementing it how you need it

[frail dust]

Yup. I literally wasted months into that thinking that it would increase my knowledge. But it made my brain go Auto Pilot mode. This is the time where I actually started learning concepts properly and then trying to apply them in small projects.

[frail dust]

Regarding that, I was just asking what all things necessary for a good game programming portfolio?

[lean sail]

I cant really answer that myself, this might be more of an industry question though not sure what channel itd go in here. You could look online but at least one general thing I know (not specific to game dev) is that people usually dont look through your code. It's a major hassle to do so and they just wanna see the final product

[frail dust]

okayy I understand

[mossy oyster]

while(GameObject.FindWithTag("LevelEnd") != null){
            Destroy(GameObject.FindWithTag("LevelEnd"));
        }

Any idea of why that would create an infinite loop?

[lean sail]

This definitely should be in #💻┃code-beginner

Look at the docs for destroy, it isnt destroyed instantly.

[mossy oyster]

Sorry abt that, idk what are beginner errors and what aren't

[mossy oyster]

Ah

Thanks

[lean sail]

If you're a beginner, it likely belongs in the beginner channel

But please cache those objects in an array or something. This hurts to look at

[mossy oyster]

Well this is only for helping me making my levels it won't be part of the final game so it's no big deal

Changed to DestroyImmediate (it also fixed the problem that Destroy() is only effective at runtime and not from the editor)

[wraith cobalt]

Do a couple of small gamejams, perhaps?

[clear oriole]

Input.mousePosition;

Why is this so inaccurate for UI its like pretty far off from the mouse position

[somber tapir]

it's not inaccurate, it represents the exact position of your mouse on your screen, so 0, 0 is bottom left and 1920, 1080 is top right (assuming that's your resolution).
You are probably not converting it correctly.

[rigid island]

depends how you are applying the position. Input.mousePosition is simply Pixel Screen Space, because UI also accounts for Canvas scale

most cases with UI you want to move the anchoredPosition of the rect transform

[vagrant blade]

If it's just generic settings, then it's fine. That's what player prefs is for.

[rigid island]

save to file or PlayerPrefs

[lone bone]

Unexpected behavior from GridLayout.WorldToCell()

Everytime I write a new thread, the act of typing it all out brings me to a solution....

You all are my rubber ducky.

[lean sail]

You are likely better off not using it. If you have to save anything custom you're gonna be writing it to file anyways. Might as well just save everything using the same method, and at least writing to file is easily visible for everyone.

[spare island]

(dont use playerprefs for anything besides maybe options)

[plush ridge]

i have a script that checks what type of ground the player is on and then plays the footsteps accordingly. the terrain stuff works great, the gameobject stuff not at all, it plays the sound of the terrain underneath the gameobject with collider even though layer name checks out.
does anyone here know why?

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

[spare island]

yeah, but to be honest its very inflexible

the benefit to using playerprefs is that its persistent between installations

thats also its downfall, you usually dont want save files to be tied to windows registry

or whatever platform its on

yeah

its more flexible, convenient for you and for the user

you could also argue that for the use case of settings, if you want them to modify settings you could leave them in a plain json file

[cold parrot]

use json, anything else is extra work thats a pain to replace.

[cosmic rain]

Depends on what you mean by a "file type". If you mean the extension, it doesn't matter at all . You can even have extension less files and that wouldn't affect the contents of the file. Now the contents are up to you, but generally they're either in a text format(like json, xml or just plain text) or binary(which you'd need to know how to interpret otherwise it would just look like a sequence of 0 and 1).

[calm mountain]

Format!

[chilly surge]

If you foresee the possibility of format changing and you still need the ability to load older formats, you should also have some way to identify the format version. A common approach is to just have a version field in your content.

[zealous vector]

Heya Im trying to make my character rotate towards where the mouse is hitting in the scene. I'm using atan2 to calculate the degree to point to and everything works well until I begin to move. The further I move the more innacurate it gets. Any clue why this could ve happening?

This is in update()

  //WorldPositionOfRayHit
  worldPos = GetMouseLookAtPos(Input.mousePosition);
  //Get the degree to face relative to player and ray hit
  float targetAngle = Mathf.Atan2(worldPos.x, worldPos.z) * Mathf.Rad2Deg;
  //TurnSMoothly
  float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
  //Rotate on y-axis to the degrees given by atan2
  transform.rotation = Quaternion.Euler(0f,angle,0f); 

 public static Vector3 GetMouseLookAtPos(Vector3 mouseScreenPos)
    {
        RaycastHit hit;
        //Cast a ray from mouse to world
        Ray ray = Camera.main.ScreenPointToRay(mouseScreenPos);
        
        //If it hits something return the place it hit it
        if (Physics.Raycast(ray, out hit))
        {
            return hit.point;
        }

        return Vector3.zero;
    }

[wide terrace]

I think that the calculated angle is relative to the world origin rather than the character's position. I believe you just need to subtract the character's position from your worldPos before finding the Atan2

[zealous vector]

yep that fixed it thanks!

[grave otter]

Hello, Im trying to update two different score vairables that are inside of a pause menu. I keep getting NullReferenceExceptions saying that the Object reference not set to an instance of an object even though I have done this. Please help!!!

[vagrant blade]

Make sure you don't have two of those scripts in your scene. Search the script name in your hierarchy.

[grave otter]

Legend!!! thank you so much!

[spark stirrup]

Sometimes randomly I can't place or target a gameobject (they are 100% clones of other ones):

https://gdl.space/fivamajube.cs

[leaden ice]

The only thing to do is debug

[spark stirrup]

in what way specifically?

[leaden ice]

In the normal ways. Log important values and if conditions and see what's going on

[spark stirrup]

Alright

[leaden ice]

Debug.Log, and/or the debugger in your IDE

I'm experimenting with procedural animation, and I am trying to make this little worm guy, but I am having some trouble. Here is my script: https://hastebin.com/share/gesiqonufe.csharp. I think whats happening is the segments are folding in on themselves, is there a way I can prevent them from folding in on themselves, without making them collide with eachother?

Oh, my bad

Here is a video of the issue: https://streamable.com/kcrv6h

[empty elm]

I recently learned that not unsubscribing to an event causes the subscribed object to not be garbage collected properly after its deletion.
I know this is bad practice since it doesn't free up unnecessary memory but my question is does it cause any unexpected behaviour in/after the deletion of the object? As far as I understand the reference to the subscribed delegate still exists and it gets called but it does nothing. I tested this scenario and nothing crashed.

[next quiver]

what does <> in class declaration mean ? e.g. public class Grid<TGridObject> { { }
is it related to generics?

[empty elm]

Yes TGridObject is the generic type parameter of Grid class. TGridObject isn't an actual type but when you create a Grid you will have to specify what its type parameter is and every instance of TGridObject in the Grid class will be replaced by the runtime type.

[next quiver]

thanks!

[next quiver]

that's a bear by the way

[spark stirrup]

If i'm running a script from the event trigger thats on another object how can I get the object that is calling the script?

[indigo tree]

By event trigger did you just mean event? If that is the case, you can have the object as a parameter and feed in ‘this’ (if you wanted the invokers class) or ‘gameObject’ (if you wanted the invokers GameObject) whenever you invoke it

[keen lantern]

Is anyone good with decoding error messages? Im not sure what this means or why I cant use this. The docs say that I can use Network Objects but its obviously still returning an error

(2nd image is a screenshot of the docs)

And for more info, the _nobPrefab is a network object
[SerializeField] private NetworkObject _nobPrefab;

[spring creek]

This is a very simple error in plain english. Just look at the method. It takes two parameters. You passed one.

It wants a bool for the second parameter. It is called asServer

[keen lantern]

oh I see it now

I didnt know that it shows you what it needs

thats cool to know

thanks!

[raven orbit]

whats the difference with transform.Rotate and Transform.Rotate

[indigo tree]

lowercase transform isn’t a class. transform is a parameter inherited via monobehavoir

It is just different target

[raven orbit]

oh okay, thank you

[cosmic rain]

First one is an instance method. The second one is a static method.

That being said, Transform doesn't have a static Rotate method, so I'm not sure where you're seeing that.

[raven orbit]

I’m not sure what that means, I just got an error and changing Transform.Rotate with transform.Rotate fixed it so I was wondering

how do I start making things without tutorials, I’ve been trying but I just don’t know how to start I know nothing

[cold parrot]

You had a typo then. Transform is a recognizable name though, since that’s the type (class) of the transform property

[raven orbit]

oh okay

thank you, I appreciate you for helping me

[vale bridge]

Does tweaking variables in the editor work because of reflection + serliazation? More specifically for the private variables I suppose

[lean sail]

pretty sure it does, also anything string based is gonna be reflection

i dont think theres really another way to get the list of fields that a class has

[rough sorrel]

Hi. When overriding a void, is it normal that even when using the base void, and in the base I do return, it still does what is in the override? Like for example, if I have the following:

 protected virtual void FixedUpdate()
    {
        if (!IsReleased || (ReplayManager.inst!=null&&ReplayManager.inst.ReplayPlaying))//this returns true, so it should do the return
 return;
}
protected override void FixedUpdate()
    {
        base.FixedUpdate();
//some more code here
}

And it is still running the part of "//some more code here", even tho it had a return in the base

[lean sail]

It is a function or method, not a "void". A lot of the terms you're saying make no sense
You're calling the base fixed update, so itll run and return back to your method call of it. Return is not some magic which stops execution of everything

[rough sorrel]

Oh okay, I thought return stopped like that method from continuing executing. My bad. I'll have to find something else then

thanks

[lean sail]

this looks like the base class isnt even doing anything in that method. If you just have that logic in the derived class itll be easier for deciding what logic should happen next

[rough sorrel]

that wasn't the full code, it was just the part that was causing some problems, but yeah, otherwise it wouldn't make much sense😅

[raven orbit]

could anyone help me with this?

[lean sail]

Why without tutorials? You should be googling for guides or what others have done when making a system that you're not sure of.
And simply you just need more experience coding

[raven orbit]

i thought tutorials wouldn’t get me anywhere but I’ll take ur advice

thank you very much

[lean sail]

In all subjects, if you're blindly copy pasting then it wont teach you anything. You need to see what others do and experiment around

[raven orbit]

I’ve been trying to understand all the code but I’ll start experiment with it as well

[cold parrot]

Test yourself: can you rebuild it without looking at the reference a week later. If you can, you have learned it, if not you didn’t learn enough. If you recreate it by memorizing, you likely also haven’t learned it yet.

The idea generally is that if you understand something once, it will be impossible to forget. If you forget you have not understood it.

[raven orbit]

most of the time it’s the math I dont get, I’ll keep trying though

[cold parrot]

Well, understanding math takes a lot of effort. Very few make that effort outside university.

[raven orbit]

I’ll try my best thank u for your advice

[fickle birch]

Hey guys

I'm trying to create a 2D Wall that starts off invisible but fades in to become opaque as the Player gets closer in its Trigger

Does anyone know a good tutorial for it? My code works but the problem is that when the Player is inside the Trigger the Wall keeps fading in from 0 to 1 alpha every time the Player presses an input

[knotty sun]

at a guess you woould want a raycast and a Lerp in OnTriggerStay2D

[fickle birch]

Thank you, I actually just figured it out by accident

[knotty sun]

actually you dont even need the raycast, the Collider info can give you a distance

[fickle birch]

How so?

[knotty sun]

Vector3.Distance from the player to the collider and feed that into the Lerp

[fickle birch]

I didn't use a Raycast or Lerp, just a Coroutine that does this

wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, wallSprite.color.a + Time.deltaTime * fadeInSpeed);

Lerp and MoveTowards were giving me funky results

[knotty sun]

that will not work for 'less transparent the closer the player gets'

[fickle birch]

You're right, but I spent an hour+ on that problem so I'm happy this works lmao 😅

I'll try one last time with your method

[fickle birch]

Oh wait, Vector2.Distance, I did try that

[knotty sun]

yes, and you need to convert that into a value between 0 and 1 for the Lerp

[fickle birch]

  private void OnTriggerStay2D(Collider2D collision)
    {
        if (!playerInTrigger) { return; }

        // If the Player stays in the Trigger
        if (collision.gameObject.CompareTag("Player"))
        {
            // Calculate the distance between the Player and the Wall
            float distance = Vector2.Distance(collision.transform.position, transform.GetChild(0).position);
            // Calculate the alpha of the Sprite based on distance and maxDistance
            float alpha = Mathf.Clamp01(1 - distance / maxDistance);
            // Update the wall's color with new alpha value
            //  wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, Mathf.Lerp(wallSprite.color.a, alpha, Time.deltaTime * 5f));
            wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, alpha);

        }
    }```

Hmm, maybe I don't understand what you mean but when I used the above method, the input problem still existed and the fading out was instant while only the fading in was smooth

even though they use the same logic and I even tried a slower fading out than in speed

It's like the Wall reevaluates every time I press an input when I'm inside the trigger and starts fading in from 0 alpha again

[knotty sun]

look at it this way
onTrigger enter you have a player position and a collider position. this gives you a distance which is your total distance.
in on trigger stay you calculate the current distance between the player and the collider and then use that to calculate a factor of the total distance, 1 - that is your Lerp t

[fickle birch]

  private void OnTriggerStay2D(Collider2D collision)
    {
        if (!playerInTrigger) { return; }

        // If the Player stays in the Trigger
        if (collision.gameObject.CompareTag("Player"))
        {
        // Calculate the current distance between Player and Wall
        float currentDistance = Vector2.Distance(collision.transform.position, transform.GetChild(0).position);
        
        // Calculate the lerp factor based on the current distance
        float lerpFactor = 1 - Mathf.Clamp01(currentDistance / maxDistance); // maxDistance is a private var
        
        // Apply the calculated alpha
        wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, lerpFactor);

        }
    }```

oops

[knotty sun]

not sure why you need the Clamp currentDistance / maxDistance should never be > 1

[fickle birch]

True

redundant I guess

compiling

[knotty sun]

one problem is this
wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, lerpFactor);
you should have a startColour and an endColour not reuse wallSprite.color all the time

[fickle birch]

The input reevaluation still exists :/

[knotty sun]

but there is nothing there that deals with input so how?

[fickle birch]

I don't know, maybe it's because OnTriggerStay runs every frame or something, I'm not sure

[knotty sun]

that has nothing to do with input

[fickle birch]

Do you see any problem in the way I'm calling my coroutines

  private void OnTriggerExit2D(Collider2D collision)
  {
      // If the Player exits the Trigger
      if (collision.gameObject.CompareTag("Player"))
      {
          playerInTrigger = false;

          // Stop any ongoing fade coroutine
          if (fadeCoroutine != null)
              StopCoroutine(fadeCoroutine);
          // Start fading out the wall
          wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, 1f); // hard coding full opacity here because of funky behavior
          fadeCoroutine = StartCoroutine(FadeOut());
      }

   private IEnumerator FadeOut()
   {
       // Gradually decrease the alpha value to fade out the wall
       while (wallSprite.color.a > 0f || (playerInTrigger == false))
       {
           // wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, Mathf.MoveTowards(wallSprite.color.a, 0f, Time.deltaTime * fadeOutSpeed)); // Faster fade out
           wallSprite.color = new Color(wallSprite.color.r, wallSprite.color.g, wallSprite.color.b, wallSprite.color.a - Time.deltaTime * fadeOutSpeed); // Faster fade out
           yield return null; // Wait for the next frame
       }
   }
  }```

[knotty sun]

apart from the facxt that it should be using the Lerp factor last calculated in Stay to go back to zero and the same incorrect usage of wallSprite.color, no

[fickle birch]

Sorry I forgot to update that, but I'm not sure it will solve the input issue

[knotty sun]

but this has absolutely nothing to do with input so I don't see where that can come from

[fickle birch]

Yeah, it's strange, it doesn't happen when I do the non-distance dependent method. I've spent 2 hours on this, better to move on 😅 Thank you very much for your help

the distance dependent opacity would be a bit fancy anyway

#copium

[knotty sun]

It's really not that difficult and is a quite common mechanic

[fickle birch]

I know 🥲

I've done it Unreal

[knotty sun]

yeah, but I bet you just used blueprints rather than writing the bare C++

[fickle birch]

No lol, it was C++ but I admit I followed a tutorial

[worn star]

is there anyway for an animator event to call a function in a script not attached to the same object

[somber nacelle]

pretty sure the answer to that is "no" but you can always have the animator event invoke some method that invokes another event that your other objects can subscribe to

[amber depot]

Guys I am trying to play a video via Video Player component on a 2d canvas, I am using a basic lit URP mesh rendered material (color: white). As soon as I press the button to display the video, it still remains white. I can hear the voice but nothing show up and am getting this debug.log "Unexpected timestamp values detected. This can occur in H.264 videos not encoded with the baseline profile. Timestamps will be skewed to correct the playback for C:/Unity/OKI! Friends/Assets/Voicecall Video/Demo_Video_NEW.mp4"

I have not transcoded the video in unity still as the codec is already H264

For unity localization package, how can I get the percentage formatter {x:0%} to work correctly? or do I have to implement my own custom formatter for this?

[sweet current]

Help me:
I did...something and now when i want to select and move objects i can hover over all vertices instad of having the object selected.

• What is that called?
• How can i disable that?
• if i hold ctrl the transform-gizmo is set to the pivot of the object, ...i think i accidentally activated something

[leaden ice]

Look at the top of your scene view

Probably ProBuilder vertex mode

Switch back to Object mode

(this screenshot is too zoomed in/cropped)

Also this isn't a code question

[gray mural]

What would be the correct way to make a Texture, used in the custom Editor's GUILayout.Toggle's GUIContent, smaller, as it is displayed with its original size? Does copying the Texture and changing its size sound fine? If so, what would be the most suitable way to do this?

[leaden ice]

Doesn't it use whatever Rect you pass it?

[gray mural]

No, it doesn't

[leaden ice]

Pretty sure it does.....

hi! i'm trying to build asset bundles on apple arm, i'm using this:
BuildPipeline.BuildAssetBundles(assetBundleDirectory, BuildAssetBundleOptions.None, BuildTarget.StandaloneOSX);
but i think StandaloneOSX only supports intel

is there anyway to get arm working?

[gray mural]

I see, that's GUI.Toggle. It's different from GUILayout's and I am still not able to change the Texture's size

[loud wharf]

I wonder if once unity moves to coreclr, do we still have to deal with assembly reference files and unity overwriting every cs project files?

[topaz hinge]

speaking about Unity's Localization tool... is there a way to know whether a LocalizedString that contains other LocalizedStrings as values for its variables is ready?

I came across this problem yesterday, in which my localized string would just print an empty string instead of the localized string value it contained... I tried running RefreshString() over and over, but it would return false every single time... I had to subscribe to the StringChange event, but it was kind of a bummer to do lol... I would have preferred to have a coroutine to wait until it is ready and then set the value (I know it wouldn't update if I change the language, but I can handle that)

[sweet current]

Oh, i got the wrong channel. Oopsie. It was not ProBuilder Vertex mode, it's in object mode.
Edit: And it's gone after restart. Well now i will never get to know what that feature is. ^^

[full gorge]

Anyone that knows a bit about serialization available to help a bit?

[rigid island]

https://dontasktoask.com

[full gorge]

I am setting up a save/load system in my game and having some doubts about the reliability. My game data is stored in a single, "master" C# class (not monobehaviour nor scritableobject) named GameState. I can serialize it all without any issues using JsonUtility, and it SEEMS to be working alright for now.

For other normal serializable classes, all the relevant data is there and it seems to be OK.

Now, when I get to ScriptableObjects, things are looking a bit iffy. I know already I cannot serialize the SOs themselves, this is not what I am trying to do. What I am trying to do is just store the references to them in my save file so when I load the game, they get put back in their positions. This SEEMS to be working for now, but the save file has "Instance_ID"s for each, and those are NOT permanent, right?

I looked around a bit and only found some really old posts talking about that. Do any of you know if any recent unity update fixed that behavior somehow or if this is still an issue?

What are my options here? Dropping SOs and using normal classes for all serializable data? Or setting a dictionary so jsonutility saves and loads them with "other names" in order to make it work properly? The second approach would be a bit complicated because my SOs are quite spread around in my data tree.

[full gorge]

I was typing the question! Hahahaha

Should have put it all together, though, sorry for that.

[leaden ice]

No that's not going to work

you need to have your serialized data reference the SO asset in a different way

For example by name to use with Resources.Load

or with an Addressables Asset

or with some custom identifier you make that you know how to resolve to an actual reference

[full gorge]

Yeah, that's what I thought. Dang it. If JsonUtility just got the GUIDs of the assets it would be so much simpler T.T

I see

[leaden ice]

or, yes, drop SOs in your serialized data entirely

[full gorge]

Got it. Either drop SOs or transform their references into something else and manage a way to put them in their slots when loading.

I will look into the addressables, maybe. Because I've read "resource.load" can be a bit bad performance-wise?

I thought about just creating a dictionary of all my SOs x Unique identifier but I have no clue of how to make the game read that and find the assets (beginner here). The closest to that would be Resources.Load, correct?

[leaden ice]

Yeah the dictionary idea is good

yeah you could do that. basically something like this (contrived example):

[Serializable]
public class ItemData {
  [SerializeField] private string itemId;

  public ItemSO GetItemSO() {
   return ItemDictionaryManager.Instance.GetItem(itemId);
  }
}```

[knotty sun]

An Array may be better, if the SO's inject themselves into a fixed index of the array and the reading classes read from that index it's just a case of storing an int on both sides

[full gorge]

This seems interesting. I will try implementing something similar.

[full gorge]

Maybe a List would be better so I can scale my data up while I produce new objects and whatnot, no? That is, if I want to keep it simpler like that.

Or maybe set another SO that just has lists for each type of SO in my game and somehow make this interact with the serialization/deserialization.

[leaden ice]

the problerm with a list or array and depending on index is that you can't ever rearrange that list or array or remove things from it

[knotty sun]

no, because you would have to ensure the correct sequencing adding to the list, with an array you dont have that problem

[full gorge]

So then the SOs will be organized such as "Armor[1]", "Character[5]" and so on, always being unique.

True

[leaden ice]

even when you update the game

[full gorge]

Removing breaks everything

Didn't consider that.

[full gorge]

But an array has a fixed size, no?

[knotty sun]

yes, but you wont be creating new so's at runtime will you

[full gorge]

Not at all

[knotty sun]

so fixed size is not a problem

[full gorge]

Hmm... I can make it generate for every SO of a type within the contents folder and it will have the exact size always, right? However... What if I ever remove an object like Praetor mentioned? The other slots won't "move" but that one will be left empty correct? Would a dictionary be better with that? Or just setting an UID inside the SO itself and making the game read it and look for that when populating the slots?

[knotty sun]

tbf you could implement the Dictionary approach for ease of development and switch to an array for production. The change would be trivial

[full gorge]

That makes sense. While I am changing stuff keep it all as a dictionary to avoid messing up and then when stuff is more set in stone, change to an array.

But how exactly do I integrate any of those approaches with the serialization/deserialization process? The serialization is actually straightforward, my issue is with the deserialization.

How can I make the engine populate the SO slots with the original SOs after it reads those unique identifiers?

[knotty sun]

you just need to store the itemid on both sides

[full gorge]

Hmm... I don't quite follow. Which sides you mean?

[knotty sun]

well on the so itself and the classes using the SO's

[rugged goblet]

Just use a dictionary, no reason for an array

[knotty sun]

Then you have code in the OnEnable of the SO so it injects itself into the Dictionary

[rugged goblet]

Use a human readable ID rather than an index, you'll save yourself so many headaches

[full gorge]

Yeah I think a dictionary is simpler for me especially since I am kind of a beginner still. But if performance is worse or something, I don't mind learning.

[rugged goblet]

The performance difference is miniscule

[spring creek]

Dictionary is more complex to use, objectively

An array is just about the most simple collection there is

[full gorge]

Oh okay! Now THIS is interesting. Just have all SOs have an OnEnable to autoinject wherever they find "themselves"

[knotty sun]

yep

[full gorge]

Love this approach. Will make it really uniform and straightforward (useful so I don't get swamped in complicated logic lmao

[full gorge]

Yes it is! But for readability it is a bit more complicated! Because "LongSword001" is easier to identify than "Weapon[008]", especially for a beginner like me. Or I think at least hahaha

[knotty sun]

your dictionary can be static or attached to a singleton just to make life easier still

[rugged goblet]

Most importantly, your dictionary doesn't depend on some abstract order

[full gorge]

Yeah, the methods I was trying to come up with would put those "onenables" on every class that had SOs, that is why I was considering just dropping SOs altogether lmao

And actually, base C# classes don't even have onEnable.

So it wouldn't even work. But putting OnEnable methods on all SOs that go into serializable classes is WAY easier and uniformizable. You saved my life there @knotty sun! Thank you VERY much!

[rugged goblet]

If your weapon data is just represented on a ScriptableObject, I wouldn't necessarily do that approach...I would use POCOs and serialize them to a file to be loaded at runtime

[spring creek]

Base c# classes don't really have anything of course

They have this:
https://learn.microsoft.com/en-us/dotnet/api/system.object?view=net-8.0

[full gorge]

Oh? What is a POCO exactly?

[rugged goblet]

Sorry, Plain Ol' C Object

Just a basic normal object

[spring creek]

What you called a base c# class.
Same thing

[full gorge]

Oh! You mean using base C# classes, right? Got it. Yeah I thought about that as well, but having the ease of creating new weapons as separate assets and handling them in the inspector and having the data preloaded into the game on starting is so useful.

But yeah, it is also an option, of course.

It's just that being a newbie in unity, the more "visual" approach of the SOs really caught me. But if setting them up becomes a nightmare I can just keep serialized stuff away from them and use them only for permanent stuff.

[rugged goblet]

Yeah, it's probably more work than it's worth for you, and the overhead from the ScriptableObjects is negligible in the grand scheme of things

[full gorge]

And the solution Steve offered should work like a charm too! I will try it out now.

Then again... OnEnable is called when an object is enabled, right? SOs get enabled when the game loads so would it actually work like that?

[knotty sun]

there is even another way of doing this.
say you have a serializable class
mySOs { public int key; public ScriptableObject so; }
and a Mono class

MySOs : Monobehaviour {
static Dictionary<int,ScriptableObject> soDict;
mySOs[] mysos;
}
then you can just store all your so references on an empty gameobject

and build the soDict as part of the Deserialization operation

[full gorge]

I see... I will explore those and report back when I manage to implement. It would be so good if JsonUtility just used GUID instead of Instance_IDs though... lmao

[knotty sun]

even if it did it would do you no good, there is no way to get from a GUID to an asset at runtime, only in the editor

[full gorge]

Oh, dang. Yeah, so nevermind ahahaha

I am trying to implement the dictionary in a way that it actually "works" during the serialization/deserialization so the class it returns is just right from the get go to replace the "old" one.

If this works the problem is solved. If not, I will try the other approaches.

[robust mantle]

Hi! I'm trying to lerp an angle from (for example): 315 to 45. I want it to not do a full 180 around to get to 45 but it does that. What's the best way to achieve that? https://gyazo.com/f87b411c34a0891d810bada51e38c924

This is my script for that:

        float angle = Mathf.Atan2(target.transform.position.x - transform.position.x, target.transform.position.z - transform.position.z) * Mathf.Rad2Deg;
        if (angle < 0)
            angle += 360;
        transform.eulerAngles = new Vector3(transform.eulerAngles.x, Mathf.Lerp(transform.eulerAngles.y, angle, lookLerp), transform.eulerAngles.z);

^ If i dont do the angle < 0 statement it spins around in circles since its a negative angle and kinda fks up so if you know a solution to that too thatd be nice

[full gorge]

Serializing classes with Scriptable Object references

• UID Dictionary: Set a dictionary to store all SOs and their respective UIDs. This will be populated on Awake of the GameManager object by a populating method that fetches all SOs currently referenced in the game for use during saving and loading the game.

• Saving: Call the SaveGame() method in which a copy of the current GameState is instantiated and processed by replacing all SOs by their UIDs from the dictionary. With that done, run the JsonUtility to serialize.

• Gameplay: You can play the game as normal, since the original GameState has not been modified.

• Loading: Call the LoadGame() method to deserialize with JsonUtility as usual, then substitute the UIDs everywhere in the GameState with their corresponding SOs (SO subtypes are kept). Finally, replace the current GameState with its processed version.

And done, the SO references will be kept in a more secure way instead of using Instance IDs.

Thanks a ton to everyone that helped! ❤️

They're not wrong, though, this isn't the place to complain about built Unity games

Nobody can answer your question here, as nobody here is the developer of the games you're having issues with.

So, the answer to the question is : you can't know. Only developers will have access to the profiling tools

This is purely a development server for people using Unity to make their own games. Any questions/issues you have with existing games isn't suited for this server.

You may want to ask them directly in their community discords, if they have them.

Goal: Animation plays when LoadingScreenWillDeactivate is invoked from LSM
Obstacle: LoadingScreenWillDeactivate (L33) seems not to be invoked, but @L31 - @L34 do execute. I'm assuming it's not being invoked because in AC @L15-@L16 do not execute. Placing a breakpoint on L33 has no result, it does not break.

AC (Animation controller)
https://hatebin.com/kojnlgbkfc

LSM (Loading Screen Manager)
https://hatebin.com/oqtcqjvlda

I think the most likely issue is the Destroy call, but the call is delayed and shouldn't stop the delegate invocation anyway
edit: removing the destroy call does nothing. the loading screen is not destroyed and the animation still does not play

even then i'd expect the invocation to succeed but to get a "this object is destroyed" error on the animator

There are no exceptions

animator is not null and animator does have bool 'IsDone'

oh wait i think i figured it out? i think my service getter wants me to use ILoadingManager instead of LoadingManager

nope

its returning the service so it should be subscribing to the event fine..?

maybe interfaces dont like events..? i don't understand

Event not being invoked

Setting the rotation with t.eulerAngles = someVector3 causes the object to sometimes flip 90° on a direction that shouldn't change at all.

What should I use instead? I tried t.rotation = Quaternion.EulerRotation() but that seems to be deprecated.

isnt it just .Euler now

Hi all, I just wanted to know if this code is OK? https://pastebin.com/DY7setf3

[leaden ice]

The way to find out is to test it

As for memory leaks - use the memory profiler

fair enough, just not sure about the behavior of dynamically allocated resources (new Texture2D and Sprite.Create)

I am supposed to destroy them manually?

[iron vortex]

Does anyone know how to pass a reference to a MonoBehavior method to a static function so that I can call a coroutine from within it?

[hidden flicker]

How do I store the changes made to a scene during runtime into the scene file itself?

[merry surge]

i am very confused by transform.TransformDirection

if my transform's rotation euler angle is 0,90,0 and i do TransformDirection on an euler angle of 0,270,0 the output is still 0,270,0

[spare island]

there's not an easy way to do that

[spare island]

rephrase?

to a monobehaviour to a static function is confusing

[iron vortex]

Sorry it turned my brain to mush

Basically I need to call a coroutine from within a static function, but you can't do that normally because it needs some kind of reference to an object that's under MonoBehavior

idk how to do that in code

well I've tried a few ways

[hidden flicker]

Surely it's not impossibly hard. I'm just talking about having a scene which stays consistent between playsessions. Many, MANY games have that

[naive swallow]

Which monobehaviour do you want to run the coroutine?

[spare island]

Yes its called a save system and serialization

[hidden flicker]

Cool. How do I do that

[iron vortex]

it can be the same class that the static function is a part of, doesn't really matter

[naive swallow]

Which instance

[iron vortex]

I guess the script instance itself

[naive swallow]

Which instance

you could have this script on a trillion objects for all it knows

[spare island]

[spare island]

Player prefs (not recommended), JSON serialization, Binary Formatting (not recommended)

[grizzled ibex]

What's wrong with binary formatting?

[lean sail]

As long as you arent using BinaryFormatter specifically, it's fine. The only downside (or upside if you dont want users editing it) being it's not human readable

[iron vortex]

Well, this script instance only exists on just one object, so I tried to pass it through with this but I doubt the reference stays consistent

[naive swallow]

What have you done in code to let it know that it only exists on one object?

[iron vortex]

That is a good question

[spare island]

well binaryformatter specifically is insecure, its inflexible (files break when the structure of the code are changed), and its not human readable (harder to debug)

[grizzled ibex]

I understand the latter 2 but how is it insecure? That's the first I'm hearing that

Just genuinely curious!

[spare island]

BinaryFormatter has a well known RCE

https://learn.microsoft.com/en-us/dotnet/standard/serialization/binaryformatter-security-guide

Microsoft itself heavily discourages using it if you can

[grizzled ibex]

Jeez thanks for the headsup

I was not aware of this

[spare island]

On the plus side you can give your game free mod support

Lmao

[lean sail]

There are alternatives, which are listed in the same page. Writing binary itself is not an issue

[spare island]

Right, but binaryformatter is the thing most beginners hop to (besides player prefs)

And the other two reasons still apply

[grizzled ibex]

I think it's because Unity literally uses it as an example for serializing in some of their tutorials

that's very questionable

[naive swallow]

The general process of using a formatter to serialize and deserialize data are pretty transferrable

Just don't use this specific formatter

[spare island]

Well it does work

[grizzled ibex]

I'm aware, just didn't know this specifically about BinaryFormatter

[lean sail]

Could be a very old tutorial before the risks were known

[spare island]

I also used to use bf until I swapped to easy save which uses json

[iron vortex]

public static void PlayTitle(MonoBehavior instance)
    {
        if (!titlePanel.activeSelf)
        {
            titlePanel.SetActive(true);
            StartCoroutine(PlayTitleEnd(instance = this));
        }
    }```

[spare island]

Bump

[naive swallow]

So, question:

Why is this static

[iron vortex]

it exists on an object that arbitrarily is registered and sometimes destroyed conditionally

so I had to do that to make the references consistent

[spare island]

Service locator?

[naive swallow]

But this specific function can only be run when one does exist

So there's no reason for this function to be on the class instead of an instance

[spare island]

You probably want a singleton

[iron vortex]

Huh, okay that'll take me a bit to wrap my head around

Idk

The point of this is so that I can disable a fade-in gameobject so that it doesn't overlay over the other UI elements** **

my solution to this in other cases has been a coroutine to disable the object once the animation finishes, and I know there's more than one way to solve this

however as you know it's in a static function in the controller class

[minor patio]

Why am I never getting this done the right way regarding Layers.

if (collision.gameObject.layer == projectileData.layerDetection)

Doesn't work properly how am I supposed to do the if line?

[somber nacelle]

1. a gameobject's layer is not a layermask, those will not be equal to each other
2. why are you trying to compare the layer in the first place?

[dark sparrow]

I just want the projectile to only react to objects that have the Player layer.
How am I gonna do that then? When I just type in the number it works, but I want to be able to set it through the inspector and not static

[somber nacelle]

I just want the projectile to only react to objects that have the Player layer.
then just filter the collisions in the layer matrix rather than comparing the layers
https://docs.unity3d.com/Manual/LayerBasedCollision.html

[spring creek]

A layermask is kind of like a list of layers. So you cannot compare them directly

[dark sparrow]

Yeah I see its using bits, thanks for your answers I will have a look

[merry surge]

i am confused by transform.TransformDirection

if my transform's rotation euler angle is 0,90,0 and i do TransformDirection on an euler angle of 0,270,0 the output is still 0,270,0

it should be 0,0,0 shoudl it not?

[lean sail]

Your euler angles are not a direction, they are a rotation in values we can understand. The vector you have it is essentially just a really scaled up Vector3.Up

In which case both the transform up and vector3.up align

[merry surge]

Oh it's supposed to use normalized vectors?

It didn't really specify that

[lean sail]

No it does not need to be. I am saying that your vector is not a direction and you've given it a vector that's just pointing up

The object has no rotation on its X or Z. Its local up and world space up are the same

[merry surge]

Basically, I have a game object rotated 90 degrees about the Y axis and I want to determine what the local rotation of 0,270,0 is in worldspace

The result I need is 0,0,0

Maybe I'm just going about reaching that value incorrectly

[lean sail]

If the object has no parent, its local rotation is gonna be the same as the world rotation

[main oxide]

i really need help i deleted my oculus folder cus i got compile errors from the all in one sdk meta and now i got 209 compile errors

[merry surge]

I have a local object rotated 270 degrees I mean

[lean sail]

Yea it's really unclear what you need this for. What's the actual use case? Why do you need this 0,0,0

[main oxide]

now when i open unity i only got 5 errors but everything is pink and i cant find the rendering tab to make it not pink

[merry surge]

I have a sub position I calculate in this game object that's rotated 90 degrees

The sub position also has a rotation

So like, if the object rotates then I need to apply it's worldspace rotation to the local rotation value when I compute the position and rotation

Basically I want to take 0,90,0 and add 0,270,0 to it

[lean sail]

Could you not just use a child gameobject and have this done automatically?

[merry surge]

Long story but no, this is all computed data

It shouldn't be difficult, I'm basically just using the transform to convert that local position and rotation to worldspace

But the function I'm using seems to not do what I need

Converting the sub position to worldspace was easy

But this rotation function isn't giving the expected value

[lean sail]

I dont really see whatd stop you from still using a child game object and just reading off those numbers. But yea the issue is what I said above. The method you're using is expecting a direction.
Though what's stopping you from just doing what you said above, adding the 2 vectors of your euler angles?

[merry surge]

Maybe that's the correct way to do it, I just assumed that function was the right way

If a game object is rotated 0,90,0 and I transform a local angle of 0,270,0 then should it not add 90 to Y?

[lean sail]

That function would be more like "I want my object to move forward relative to itself but I wanna specify (0,0,1)"

[lean sail]

Honestly I'm not sure what to imagine in this scenario, the use of local and worldspace in a lot of messages dont fully make sense.

If your sub object is supposed to be rotated 90 degrees relative to the game object then yes just add the 2 vectors.

[golden ibex]

Hi, there. I'm attempting to create a first person controller with 6 degrees-of-freedom movement in a zero-gravity environment. I have a camera holder that moves to a specified empty child of the player object with LateUpdate. I am translating the player's rigidbody with AddForce and rotating the rigidbody with MoveRotation with FixedUpdate. (I was initally rotating the player's transform directly with transform.Rotate.)The translation works great, but the rotation causes camera jitter. The jitter is especially noticeable when translating and rotating at the same time.

My understanding is that camera jitter on a rigidbody player controller is very a very common issue for beginners. I've tried following quite a few guides on Youtube, the Unity forums, and Reddit. So far, nothing has worked. Many fixes I'm seeing don't apply to me because of my unique camera set-up and movement system. My intention is for the mouse input + roll keys to rotate the entire player object, so a traditional FP controller setup does not work for me.

Thing's I've tried: The rigidbody's interpolation is turned on and I have tried both settings for it. I have tried changing the camera holder move script to FixedUpdate and regular Update. I have tried making the camera update move and rotate to the rigidbody instead of the player's transform. I have also tried making the camera a direct child of the player object.

All three of my C# classes: https://gdl.space/yokesabive.cs First one handles the rotation inputs and applies rotation to the player's rigidbody. Second one handles translation. Third class is on the camera holder and updates its own position to be that of the player's position. (The main camera is a child of the camera holder.)

Screenshots of my editor setup are attached.

[indigo tree]

Why not add a constraint to the camera?

[golden ibex]

Can you please elaborate?

I am unfamiliar with the concept of constraints on a camera beyond a MathF.Clamp on a camera's rotation

[indigo tree]

Add a constraint component on camera holder and set the target to camera position.

[golden ibex]

Thanks, I understand now. I was unaware of constraint components. I'm testing it now.

[golden ibex]

I've now set up the constraint components and it seems to have reduced the amount of camera jitter significantly. There's still way to much for the kind of game I'm making, but now that I know about constraint components I'm going to give another technique a try.

I have a variable i want to set: inventory.wood but I don't want to write a separate line fo code for each object. Would I be able to pass in a string instead of wood? So something like inventory.(this.blockName)?

    if (GameObject.FindGameObjectWithTag("Inventory"))
    {
        GameObject inventoryObj = GameObject.FindGameObjectWithTag("Inventory");
        switch (blockName)
        {
            case "Log":
                amount = inventory.wood;
                break;
        }

jesus this is already overconvoluted

[spark stirrup]

inventory.wood is an integer

[rigid island]

so you're trying to do an inventory count?

what does have to do with dictionary

easy to pull values from

or easy to look up values i mean

[rigid island]

wat values are you talking about

using a switch for this when you can easily do it in 1 line with dicionary

[spark stirrup]

Yeah that's what i'm saying, a dictionary would be better. I just don't want to use one because i'd have to rewrite a lot of stuff

[rigid island]

the way you're doing it now is not good and not very scalable.. rewriting code is part of the work

It's tempting to "let the future me deal with it" but if you foresee your future self saying "this has gotten so bad that I can no longer continue working with this code and need to refactor it, I should've just done it two months ago and saved a bunch of time during the two months" then you might as well do it now.

How do I actually "save" values with ScriptableObject?
I have one that get filled by a [ExecuteInEditor] script, and while I can read it perfectly it get reset to null everytime I load a new scene or restart the editor.
Tried AssetDatabase.SaveAssets, but it's not doing anything so I'm kinda confused on how to do it.

[knotty sun]

did you SetDirty before Save ?

[quick delta]

I didn't even knew that was a thing.
Tested it and it look like that did the trick.
Thanks!

bro my entire project is fucked for some reason uninstalling 1 folder corrupted my project cus when i go in to the project all my plugings are gone it uninstalled all my FUCKING stuff like xr pluging manament and all and it removed all my scripts and for some reason my fucking map has a skinned mesh render now and i cant restore it

[lean sail]

Guessing you weren't using version control, in which case this is your lesson to start. Look into using git

[main oxide]

i am

[lean sail]

Then you'll have to be more specific, probably in a different channel though because this doesnt sound like it's anything code related.
If you have version control then you can simply just go back to an earlier commit where everything was fine or even redownload the project if needed from that commit

[main oxide]

bro i dont know how

i got unity version control but i dont know how to go back versions

i dont even got the tab for it

it uninstalled it

[lean sail]

I dont use unity vc, have you googled anything related to that? And have you even made commits ever for it

[main oxide]

all my plugings tabs are gone

sould i seek help in xr hub

[lean sail]

I dont really see how anything you said was XR specific so I dont know. I strongly suggest you look online for how to use or find your unity version control so you can see if you can revert. Though if nothing was ever committed then you dont really have something to revert to

                using (var memStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("bundle1"))
                {
                    if (memStream != null)
                    {
                        MelonLogger.Msg("memStream is not null");
                        byte[] byteArray = new byte[memStream.Length];
                        memStream.Read(byteArray, 0, byteArray.Length);
                        MelonLogger.Msg($"ByteArray length is: {byteArray.Length}");
                        assetBundle = AssetBundle.LoadFromMemory(byteArray);
                        var prefab = assetBundle.LoadAsset("test", Il2CppType.Of<GameObject>()).Cast<GameObject>();
                    }
                    else
                    {
                        MelonLogger.Msg("memStream is null :(");
                    }
                }

What here could cause prefab to be null?

[somber nacelle]

perhaps you should ask in the community for the game you are modding, or in the mod loader's community

[inland moon]

I have, already

[somber nacelle]

okay well this isn't the place to get help with modding, it is against server rules #📖┃code-of-conduct

[inland moon]

Alright

[rocky tide]

Hello. I have again come here and seek answers from the gods of the unity community to help with my problem. my console says after shooting the raycast LineRenderer.Setposition Index Out Of Bound. Any good tricks to fix this?

[knotty sun]

you need to set the number of positions first

[rocky tide]

Oh i got it

I called a High Priest of Unity programming and got an immediate answer

[knotty sun]

not really, just someone who can be arsed to RTFM

[keen forge]

Sometimes when i hit play button in editor, it infinitely stucks on reloading domain. Recently i discovered that is happens only when PC connected to internet. Without internet connection everything is fine 🤷‍♂️ How to fix it? My current version is 2023.2.5f1 but i tried a lot of different versions so i assume problem is in my project. ChatGPT 🤖 adviced me to figure what of my assets can use internet connection by searching words like "www" "http" and other in project, but i didnt find anything like that

[gloomy path]

does anyone know how to make a line renderer thin out over time?

[leaden ice]

LineRenderer has https://docs.unity3d.com/ScriptReference/LineRenderer-widthCurve.html

or the simpler:
https://docs.unity3d.com/ScriptReference/LineRenderer-startWidth.html
https://docs.unity3d.com/ScriptReference/LineRenderer-endWidth.html

[knotty sun]

best bet, close project, delete Library folder, open project

[gloomy path]

wrong video oops

this is the line thing I was meant to send

[leaden ice]

yes, use the width curve

[gloomy path]

oh alr thanks

[keen forge]

did it, doesnt helps

[knotty sun]

you are on a non LTS version of Unity, is there a reason for that?

[keen forge]

no

[knotty sun]

then I would suggest you either move to the latest Unity 6 preview or regress to the latest 2022.3 LTS. If you regress create a new project with the editor version and use asset->export asset->import to migrate your project

[keen forge]

i tried a lot of versions, including 2022.3 LTS, unfortunately i had same problem on it

[knotty sun]

interesting, did you check the editor !logs to see if anything odd was happening?

[final forge]

can any one help me with this script : using UnityEngine;

public class jumpscarestranger : MonoBehaviour
{
public float maxRaycastDistance = 10f;
public Transform playerCamera;
public LayerMask interactableLayer;
public MonoBehaviour playermove;
public Transform target;
public AudioSource audioSource;

void Update()
{
    // Create a ray from the camera's position along its forward direction
    Ray ray = new Ray(playerCamera.position, playerCamera.forward);

    // Check if the ray hits an object on the specified layer within the max distance
    if (Physics.Raycast(ray, out RaycastHit hit, maxRaycastDistance, interactableLayer))
    {
        audioSource.Play();
        playermove.enabled = false;
        playerCamera.LookAt(target);
    }
}

}

when it look at the interactableLayer it just turn to target without activate the sound

[knotty sun]

you are starting the audio EVERY frame

wow, i needed to make a batch file, haven't made a complicated one in over 20 years and forgot most of it ... microsoft's copilot (chatgpt thing?) basically held my hand through the whole thing, and when i had syntax errors, i pasted the whole code into it and asked how to fix it, and it very accurately fixed my errors as well as explaining what was wrong ... geez

[knotty sun]

amazing isn't it, DOS has changed very little in 50 years and it still underpins everything we do

[fickle birch]

Hey guys

I'm trying to create a Laser Trap that tracks the Player's position and rotates accordingly

It does that, but the problem is that

I want it to scale depending on the Objects it hits. So if the Player is under a platform, its Collider and Sprite should shrink so that it's hitting the platform, and then scale up again when the Player is in an open area. I do not know the right way to implement this.

But the tracking and rotating of the Purple Block itself is working correctly.

[knotty sun]

will you please learn to type in full sentences

[fickle birch]

I'm GenZ, Sir

[knotty sun]

So what, the rules of the server still apply to you
