internal class SurvivorData
    {
        [JsonProperty] public List<Survivor> survivors = new List<Survivor>();
        [HideInInspector, JsonProperty] public List<Survivor> FreeSurvivors = new List<Survivor>();
    }```

example

i send this to the GameData dictionary like this

SurvivorData data = new SurvivorData();

    public List<Survivor> survivors => data.survivors;
    public List<Survivor> FreeSurvivors => data.FreeSurvivors;

 void WriteToSave() => DataManager.SaveData(DataType.survivor, data);```

it will always save multiple objects tho? i guess that's what you've meant

[knotty sun]

but not multiple objects of multiple types

[cold parrot]

Looks like you are reinventing what a database is

[tired drift]

It's a local savegame file

pretty much needs to work like one in my head

[cold parrot]

I‘d use a local single file database then

[tired drift]

it's what it's doing tho

[tired drift]

But SaveData is generic since idk what type of data i'm getting, it can be Survivor, Inventory, Shelter, City, idk..

that's why it's generic

[cold parrot]

That’s why I said you are reinventing the wheel in a worse way (from the looks)

[tired drift]

but the dictionary collects those and saves them so i guess it does handle multiple ones?

idk how i could make it better tbh

[knotty sun]

but it is still one file per type, not multi object multi type

[tired drift]

hm

1 gameData has a dictionary with 1 key that equals 1 object

another key can be a totally different object

[cold parrot]

With SQLite for example

[tired drift]

isn't that handling multiple objects

[tired drift]

don't wanna use SQL tbh the point is having an obfuscated file

[knotty sun]

SQLite, with Unity, dont make me laugh

[tired drift]

plus JSON is easier like

[tired drift]

But does it make sense what i've said?

i mean in my head it can handle multiple types

[knotty sun]

check this out, https://stevesmith.software/save4unity.html Coming to the asset store soon

[tired drift]

but aren't you making multiple Save files and then combining them in a single one?

[knotty sun]

no

[tired drift]

hm then?

[knotty sun]

one save file, containing anything you want

[tired drift]

but that's what mine is doing? 😅

1 Save file is handling multi-type, if i'm not wrong, SurvivorData and InventoryData aren't the same right?

[knotty sun]

no it's not, you have one call to save, which means you have one class defining everything you want to save

[tired drift]

hm

[knotty sun]

your code cannot call Save twice on the same file

[tired drift]

how so? sorry i'm kinda slow cuz i didn't sleep much today

[knotty sun]

you have no append, no indexing, no file descriptors

[tired drift]

wdym indexing?

i'm utterly confused

[knotty sun]

I mean, pulling individual objects out of the save file

[tired drift]

you can tho

wait let me show you how the save looks

{
  "_saveData": {
    "0": {
      "$type": "Core.Data.SurvivorData, Assembly-CSharp",
      "survivors": [
        {
          "movespeed": 20.0,
          "isBusy": false,
          "isInShelter": false,
          "name": "Donald Hall"
        },
        {
          "movespeed": 20.0,
          "isBusy": false,
          "isInShelter": false,
          "name": "Kathleen Lewis"
        },
        {
          "movespeed": 20.0,
          "isBusy": false,
          "isInShelter": false,
          "name": "Thomas Jackson"
        }
      ],
      "FreeSurvivors": []
    }
  }
}```

it will take the 0 out which is all the survivors and free survivors out of the list

1 would contain inventory

2 shelter / city etc etc

[knotty sun]

no, you have to load all of them in order to be able to access any one of them. If I want, only e,g, survivors number 1 then you cannot do it

[tired drift]

ah it's not the point either

but i can create a method for that

can i not?

[knotty sun]

no you cannot, that is not the way Json works

it is all or nothing

[tired drift]

i mean, SurvivorData is a list, and i really won't care much with the individual aspect of 1 survivor

[steady moat]

You can separate in multiple files.

[tired drift]

at least on the game design it doesn't matter much, and from the top of my head i don't see where being able to handle 1 survivor or 1 piece of info can be necessary. (does it make sense?)

i really just want to pick up a list of x things and read and load them. But i'm always open to other POVs

[knotty sun]

exactly, you have to separate into multiple files, that is why I say this design paradigm cannot handle multi object scenarios, plus the fact that Json is just crap for games

[tired drift]

I'm using JSON cuz it's simply faster at this point of development, plus it's nothing serious for now.

but do you think i should go for something where it can handle 1 object inside the list at the time?

It's like i've said, i don't really need to access that type of info during loading, since it's not really important hence the why i've made it this particular way

or saving 1 specific survivor

[knotty sun]

it's not about 1 object in a list, but say you have 10 lists, being able to load one of those without having to load the other 9 might be nice

[tired drift]

i mean i only considered of doing loads during the start of the game / whenever a save is loaded

[tired drift]

hm.. so what would you suggest? creating several variables instead of a dictionary?

where i can serialize those objects inside the save?

[knotty sun]

You need to add a structure to your save file, on top of your Json, that way you can access parts of the file without having to pay the overhead of accessing all of it

think about the way that FAT tables work on disks

[tired drift]

trauma

but what type of structure would that be i mean, like inside the json or outside, where the json would be inserted?

[knotty sun]

Sorry, I'm not trying to be cruel, this is just the way computers actually work

[tired drift]

i know heh, dw i actually want to make a decent save & load, the more i learn the merrier

[heady iris]

Serialization is always traumatic

[knotty sun]

just buy mine when I publish it,leave the grief and agrivation to me

[tired drift]

now you left me curious

[knotty sun]

@heady iris is right, Serialization, done correctly, is not for the uniniated

[heady iris]

one thing that can help is separating "authoring data" from "runtime data"

for example

in my soulslike I'm working on, your inventory is full of InventoryItems

these contain instructions for how to create an actual weapon you hit things with

[tired drift]

it's like i've said, i haven't really developed many S&L systems, and the ones i've made were pretty simple compared to this one

[heady iris]

so I'm not going to have to serialize the actual weapons

just the blueprints

[tired drift]

I mean all the data i'm saving is pretty much runtime there isn't anything really authoring, at least for now. Maybe when i get to the shelter / city it may contain some type of data where that separation is needed, but ty for the tip ^^

[knotty sun]

if you are thinking about saving SO data, that is 'Authoring' either that or your design concepts are wrong

[tired drift]

i didn't make them, but i think they are authoring yes

just peeped quickly, but yeah some parts will change during runtime but most of it is authoring

[knotty sun]

then you need https://assetstore.unity.com/packages/tools/utilities/scriptableobject-pro-218340 to do the job

[tired drift]

so you're saying if the stuff i save from the SO changes during runtime it won't save correctly?

[knotty sun]

correct

[tired drift]

more changes

f

so the SO can only have the authoring parts welp

[knotty sun]

yes

[tired drift]

gonna be a pain but not for me

hmm i mean we were using SOs with some mutable variables, but i didn't even consider the save and load question at the time tbh

[knotty sun]

forget mutable variables in SO at runtime outside of the Editor, Ain't gonna work

[tired drift]

but now you left me thinking if my S&L system is too bad in a overall, even if i don't want to access a list, but instead load everything at once every load cuz i mean that's how we were thinking of doing.

[tired drift]

ty for the tip, i should have thought that from the beginning tbh

[knotty sun]

it's in the docs but, hey, nobody reads them anyway

[tired drift]

i mean i knew SO act like structs but didn't even came to my mind about when reading them after their values have changed

[knotty sun]

Biggest problem is different behaviour in Editor and in Build. Bad Unity

[tired drift]

Tbf, sometimes i wish unity would help on that end. I feel like there are some QoL things around the editor -> build that could be enhanced. But hey i ain't complaining

anyway guess i'll work on the changes once again i appreciate for the golden nuggets you've gave me

[stone rock]

Hello, when using assembly references in Unity, does everything have to be in a folder with an assembly reference or can i have a script in the default C-Sharp assembly? how can i make my assembly reference include the C-Sharp default assembly?

[leaden ice]

how can i make my assembly reference include the C-Sharp default assembly
You can't. Once you start using asmdefs you basically have to use them for your whole project.

Make a game assembly and have the other assembly reference it.

[stone rock]

so you can't have a reference to the default C-Sharp assembly then

[leaden ice]

No

[stone rock]

i see i'll add an assembly at the root of my scripts folders then

[fluid lily]

Anyone else having an issue of scripts inside Editor folders being included on build? I thought any folder called Editor wouldn't be included on build.

[leaden ice]

Shouldn't happen. Can you show an example?

[fluid lily]

C:...\Assets\Modules\Levels\Unity\Level1\Editor_Extensions\PropertyInspectors\Editor\HideInNormalInspectorDrawer.cs

That file I had to put #if UNITY_EDITOR on

[simple egret]

Assembly definitions override Editor folders, if I remember correctly

[leaden ice]

What about this file?

[simple egret]

So if you have one that encloses that folder

[fluid lily]

using UnityEngine;

#if UNITY_EDITOR
using UnityEditor;

[CustomPropertyDrawer(typeof(HideInNormalInspectorAttribute))]
class HideInNormalInspectorDrawer : DecoratorDrawer {
    public override float GetHeight() {
        return 0f;
    }

    public override void OnGUI(Rect position) {
        // do nothing to prevent the field and any custom property drawers from being displayed in the inspector
    }
}
#endif

[fluid lily]

Ah yeah I do

[leaden ice]

Yeah only thing I can think of is you have an assembly definition

[fluid lily]

That is annoying

[leaden ice]

Not really

You can just set the assembly to not be included in the build

[fluid lily]

I can see it being useful, but annoying that it isn't clear that happens

[leaden ice]

If you are mixing editor and non editor stuff in one assembly you will need to split it up though

[fluid lily]

I mean, or just compiler directive it

[leaden ice]

That's wasteful though...

Why include files in your build that have no business being there

A few clicks in the editor > writing a bunch of preprocessor directives in many files

[fluid lily]

If I have a larger number of files I would agree, but it is just that one currently.

Though also I have some functionality that can use Undo in editor(or just normal in build) so having a version of each makes sense, and then already have functionality specific to different platforms anyways.

[plush sparrow]

public class spawnRes : MonoBehaviourPunCallbacks
{
  if (PhotonNetwork.LocalPlayer.ActorNumber == 1)
        {
            GameObject sco = PhotonNetwork.Instantiate(Score.name,new Vector3(0f,0f,0f),Quaternion.identity);
            GameObject go = PhotonNetwork.Instantiate(Dice.name,new Vector3(0f,650f,0f),Quaternion.identity);
            sco.transform.SetParent(Canvas.transform, false);
            go.transform.SetParent(Canvas.transform, false);
        }
        else
        {
            GameObject sco = PhotonNetwork.Instantiate(Score.name,new Vector3(100f,0f,0f),Quaternion.identity);
            GameObject go = PhotonNetwork.Instantiate(Dice.name,new Vector3(0f,650f,0f),Quaternion.identity);
            sco.transform.SetParent(Canvas.transform, false);
            go.transform.SetParent(Canvas.transform, false);
        }
        
            
    }```

when two players are joining. they can only see their own instantiated objects

and cant see each others

what is the problem?

i have added a photon view component along with a photon transform view component to the prefabs of the instantiated objects

[simple egret]

Probably worth asking in #archived-networking

[plush sparrow]

oh ok

[simple egret]

But check if your Instantiate method here can take a parent Transform directly. It's never good to instantiate an object in world space and then parent it to UI. It messes with the RectTransform

It might not solve your issue, but it's a step forward to better object management

[plush sparrow]

ok thanks

here can take a parent Transform directly

what do you mean exactly

[simple egret]

Regular Instantiate has a version where you can pass a Transform directly to it, aside the position and rotation

Instantiate(prefab, pos, rot, parent)

So check if your networking one can do that too

[ocean river]

hey um,
ive got a question.
i have two gameobjects, and one of them HAS to be initialized before the other.
i mean the gameobjects themself tho.

[leaden ice]

Make a script that spawns one then the other

Or have the first one spawn the second one

Also you didn't actually ask a question 😂

[primal marlin]

hey guys i have a projectile which spawns an explosion particle system after it enters a collision. the issue is this explosion particle stays at the same place and doesnt happpen where the projectile has collided

https://pastebin.com/CVimB4gb

here is the projectile code

here is the projectile hierarchy

[leaden ice]

GameObject ps = Instantiate(explosionParticleSystem.gameObject)

You're not even attempting to set the position 🤔

Also you don't need the .gameObject there

[ocean river]

are awake and start called when a scene is loaded as additive?

[potent sleet]

ya

[ocean river]

but i put Debug.Log in a object, and it didnt show...

only when i load the scene directly.

[potent sleet]

where is the log, is the object enabled?

[ocean river]

never mind, it was filled with audio listener msgs so i didnt see...

[simple egret]

We don't help with modding in this server

I don't make the rules, sorry

[severe saddle]

I tried this script to download a pdf file from the given url. It works on PC but not on android. Pls help!

[buoyant shuttle]

Can someone help me out? :(. I'm trying to get the forward bounds of my collider in world space. In particular I need the center bottom forward. I marked with a red dot the position I'm aiming to get. I can't quite figure it out since bounds has size and center.. But doesn't translate from local to world etc.

[heady iris]

find the point in local space, then transform it to world space

[leaden ice]

I would do something like...

Ray r = default;
r.origin = transform.TransformPoint(Vector3.forward * 100);
r.direction = -tranaform.forward;
if(myCollider.Raycast(r, etc...)) {
  var point = hit.point;
}```

[heady iris]

oh hey, I never knew that you could do a raycast on a single collider!

neat

[leaden ice]

Yep

Also wrote this on my phone so it's a little rough

[heady iris]

but yeah, I'd just do transform.TransformPoint(collider.center + Vector3.Forward * collider.bounds.z)

i forget if bounds is half-width or full-width

if it's full-width, divide by 2

[leaden ice]

The bounds aren't quite the actual collider shape though

You can also just make a child object at the point you want

And use that position

[wide star]

someone help me fix this bug, because I'm trying to make the button turn on application from game files but something didn't work, because it can see the file but won't turn it on something

using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
using UnityEngine;

public class UEChanger : MonoBehaviour
{
    string m_Path;

    public void ChangerToUnrealEngine()
    {
        m_Path = Application.dataPath;  Process.Start("/Ognaria_Data/Resources/UnrealEngineSource/WindowsNoEditor/Ognaria.exe");
    }
}

[cerulean oak]

how does adding/removing/renaming fields work with BinaryFormatter? Does it stop working? do they get deserialized as a default value?

[leaden ice]

You really shouldn't use BinaryFormatter...

[cerulean oak]

why not?

what about xml?

or json?

but those dont have references right?

how do i handle versioning with serialization? What should I use to serialize/deserialize?

[swift falcon]

does the using directive import the entire library ?

Im asking because what if i only want one class from the library do i have to drag in everything else as well?

[lucid valley]

depends on the class and the license

[heady iris]

doesn't binaryformatter lead to code execution when deserializing malicious data

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

[swift falcon]

Oh because it may be refernecing other classes in the lib?

[lucid valley]

yeah, you probably can't just take the file on its own

[cerulean oak]

So, what should I use?

[lucid valley]

having the whole library would increase build size, but wouldn't reduce performance (unless you are really ram limited maybe)

[cerulean oak]

The compiler should be able to optimice the import of the library

[lucid valley]

pretty sure it won't unless you build for il2cpp, then it will strip

[cerulean oak]

And unless you are running whatever you are making in a potato and the library is huge, it shouldn't be a concern

The java compiler optimizes it, I don't see why the .net one wouldnt

[lucid valley]

well yeah code size isnt generally an issue for Unity games

https://docs.unity3d.com/2019.3/Documentation/Manual/ManagedCodeStripping.html

Ordinarily, the build process includes the entire assembly file, no matter how much or how little of the code in an assembly your Project uses.

No idea if that is the mono/.net default or if Unity has changed it

[heady iris]

this is for IL2CPP

[lucid valley]

it can be used for both

[heady iris]

oh, d'oh, you're right

[cerulean oak]

That's the answer to his question, but honestly, what he should hear is very likely "don't worry, it won't matter"

[heady iris]

ya

[nova roost]

Is there an easy way to check if an object is a 2D Canvas object or a 3D one?
I guess I could check if the transform component is a rect transform or a Transfrom, right?

[heady iris]

yeah

that's what I'd do

transform is RectTransform

[nova roost]

didnt know its that easy

[low horizon]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ResourcesManager : MonoBehaviour
{
    public static ResourcesManager current;
    private void Awake()
    {
        current = this;
    }


    public GameObject exampleObject;

    private void Start()
    {
        exampleObject = Resources.Load<GameObject>("exampleObject");
    }
}

is this an acceptable way for using resources folder

basically a singleton that loads them all

and other scripts get prefabs etc from that

what is the generally used method for this?

[leaden ice]

Why not just use a direct reference if you're doing this

[low horizon]

wouldn't that require dragging them all

for each scene

oh i can use prefabs

thanks

can i do static GameObject and drag them in editor

[leaden ice]

Resources.Load can only work on prefabs already 🤔

so I'm not sure what you would have been doing before

[low horizon]

i was

lost

[leaden ice]

no

static is right out for the inspector

[low horizon]

thanks

what is resources.load used for then

[leaden ice]

dynamically loading assets by name

[low horizon]

oh

[leaden ice]

honestly in serious projects, Resources.Load is not used at all, Addressables are.

[low horizon]

i don't know what is addressables

let me check them

thanks

[leaden ice]

Resources.Load can be useful for lazily loaded singletons and self-initializing singletons / ScriptableObjects

[worldly hull]

addressables lets u register all the existing position of the assets across the whole project file

and then by using the API, u get to spawn stuffs without assigning them on inspector

[leaden ice]

Addressables lets you reference assets without immediately loading them into memory

[low horizon]

it looks like the exact thing i was looking for

[worldly hull]

imagine u have 10000+ assets in ur folder, its extremely hard to find them everytime right? if u can register the stuff u want onto the addressables. You will have a simpler menu to access them

normally i wont use addressables, but my team does, even tho they use it very differently unlike the normal way

[buoyant shuttle]

Thanks! I'll try it out.

[worldly hull]

i think one of the most important reason of ppl using addressables is the decentralization

[low horizon]

to be honest i am just looking for a way to load objects without making everything complicated

when the project gets bigger referencing stuff becomes hell

[worldly hull]

just pack ur folder well bruh

but i guess addressables is fine if u have tons of stuff

[low horizon]

its like

i am using scriptable objects

that summon modular components

[worldly hull]

and i still need someone to explain more bout it to me tho
i joined a team project for like 6months, and the image that addressables left me is just bad

[low horizon]

it looks like

[worldly hull]

maybe its because how my team use it differently

[low horizon]

it lets u load stuff

with code

[primal marlin]

sorry i was away

[low horizon]

rather than inspector

[primal marlin]

how would i go aboout doing that?

[low horizon]

thats what i am looking for

so i'll try adressables

[leaden ice]

Instantiate has overloads that take a position parameter. Check the docs:
https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[worldly hull]

yeah just go try it

[primal marlin]

thx

im getting an error on this line:

Transform position = transform.position;

'Cannot implicitly convert type 'UnityEngine.Vector3' to UnityEngine.Transform'

[potent sleet]

transform.position is a vector3

[primal marlin]

Vector3 position = transform.position;

also gives error

[potent sleet]

what error

[primal marlin]

Argument 2: cannot convert from 'UnityEngine.Vector3' to 'UnityEngine.Transform'

[potent sleet]

did you save

[primal marlin]

yes

its a different error

OH DIFFERENT LINE

sorry

the line is this one

GameObject ps = Instantiate(explosionParticleSystem.gameObject, position);

can i not use vector3s for instantiate argument 2?

[potent sleet]

you need to add rotation as well

or else rn it's a Parent parameter which is only Transform

[potent sleet]

GameObject ps = Instantiate(explosionParticleSystem.gameObject, position, Quaterion.identity);

[primal marlin]

thank u!

[potent sleet]

always look into the docs when things don't make sense
https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[primal marlin]

thx

i did but i thought rotation was not necessary

[potent sleet]

for passing position it is, but yeah Quaterion.identity = no rotation

[heady iris]

there are only two overloads

Transform
Transform, Vector3, Quaternion

er

i am very wrong on that number!

there are 10, lol

[worldly hull]

GameObject , Transform

[heady iris]

oh yeah

i forgot the gameobject

lol

but yeah, there's no overload that only takes a position

[worldly hull]

instantiate(GameObject)```
i think its same as 
```cs
instantiate(GameObject,Vector3.zero,quat.identity)```

which spawn stuffs on origin

[worldly hull]

there nope

you can create one tho, even its not really necessary

public void Instantiate_PosOnly(GameObject obj, Vector3 pos){
      Instantiate(obj,pos,quat.identity);
}```

when u call this function, it will act as ```cs
instantiate(GameObject,Position)```

[knotty sun]

well, if you dont mind compile errors instead of running code

[heady iris]

you could write an extension method :p

i forget if it gets mad if you make an extension method with the same name as an existing one

[knotty sun]

no, you can overload extensions

[heady iris]

nice

[worldly hull]

oh wait

u can

that thing is transform

[knotty sun]

you're in a different namespace anyway

[worldly hull]

Instantiate(GameObject,Transform)
Instantiate(GameObject,Vector3)```

yes u can

[civic folio]

What's the difference between vector3 and float3?

[cold parrot]

float3 is used in the Mathematics package that is optimized for burst, Vector3 is the normal one used everywhere in the engine without specific optimizations

[knotty sun]

one is used in C# the other for shaders, they are both, basically the same

[heady iris]

they're basically the same thing under the hood

three floats glued together

[latent latch]

https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html
How do I go about normalizing(?) the speed for this method? I'm trying to get a constant speed such that it travels the same distance that not dependent on the radius.

[heady iris]

trig time! trig time!

well, sort of

A rotation of one radian around a unit circle will move you by exactly one unit

because the circle's radius is 1

diameter is 2

circumference is 2pi

and it's 2pi radians to make a full turn!

so, dividing the rotation speed by the radius will do the trick

[latent latch]

I fell asleep in trig. Would been more exciting if I found it useful at the time.

[heady iris]

well, you're in for a treat in game dev :p

[cerulean oak]

I added the newtonsoft package, but rider isnt detecting any newtonsoft classes

any ideas about what i should look for?

[heady iris]

you might need to regenerate the project files in the External Tools menu

[knotty sun]

how did you add the newtonsoft package?

[cerulean oak]

with the package manager

[knotty sun]

can you see it in your packages folder in the project?

[cerulean oak]

yes

[knotty sun]

you have added the correct using statments?

[cerulean oak]

ok regenerating the project files worked

[cerulean oak]

no why would I do that manually

but its working now

thanks!

[rain tide]

When ever I try to move backwards, it spins uncontrollably.

-- the script: https://pastebin.com/RuDA4J60 --

[latent latch]

Ah, ok I think I've tried that before, but I assume I've more to my problem than just that. I guess the problem now is translating linear speed(?) into that rotational speed.

[heady iris]

let's see

[heady iris]

so your goal is to rotate at a specific linear speed?

with a known radius

[latent latch]

Yeah, that's probably the idea

[heady iris]

Dividing by the radius will make it so that rotating at one radian per second makes you move at one meter per second

er

that was not the correct way to say that!

lol

[rain tide]

Hello?

[heady iris]

if you rotate by 1/r radians per second, you will move at 1 meter per second

there we go

[heady iris]

a minute, please :p

[heady iris]

so, to move at x meters per second, rotate by x/r radians per second

[rain tide]

I was just seeing if you would notice me, I'll wait, thanks!

[latent latch]

So, x in this case would be speed * Time.deltaTime or is there more to this? At the moment it's much, much slower with that than a linear projectile

[heady iris]

yes, you'd multiply deltaTime in afterwards

[rain tide]

So what are you trying to do exactly?

[latent latch]

Angular to linear velocity I would assume

[rain tide]

Angular is at an angle, so you would try to convert it to a linear line-like velocity?

[heady iris]

if you rotate with a radius of 1 at 1 radian per second, the object should appear to be moving at 1 meter per second

is it appearing much slower than that?

[latent latch]

          transform.RotateAround(sourceSpawnPosition, transform.up, ability.StatDict[AbilityStatType.AbilitySpeed]/ability.StorableSO.DistanceOffset * Time.deltaTime);```

does travel much slower than my normal fireball of ability.StatDict[AbilityStatType.AbilitySpeed] * Time.deltaTime * objectDirection;

[heady iris]

is objectDirection normalized?

[latent latch]

Ah, actually I don't normalize this one

[heady iris]

that'll do it!

[latent latch]

There's probably something I'm doing wrong beyond that, but I'll revise on what ya said

tyty

[rain tide]

Alright, good luck!

[heady iris]

so gideon, your character spins rapidly when you try to back up?

[rain tide]

Yeah.

When ever I try to move backwards, it spins uncontrollably.

-- the script: https://pastebin.com/RuDA4J60 --

I've been trying to fix it for the past 2-3 hours.

[heady iris]

i noticed that both the horizontal and vertical movement affect the y-axis rotation

[rain tide]

Really?

oh.

So what do I do to help with it?

[heady iris]

well, I don't really know what your intent is here

can you explain what this is doing?

[rain tide]

So, it's a movement script that is supposed to work with Keyboard and mouse, and controller with animations, I would of used the Input system asset, but I found it easier to do this.

[heady iris]

so it tries to rotate you to face the direction you're moving in

although you only have the vertical component on the direction vector

[rain tide]

Yeah, I use the Horizontal just for turning.

[heady iris]

but you're already turning?

i don't understand

[rain tide]

The video.

[heady iris]

ah, I see

oh

one big thing...

you add the rotation of the camera to the desired rotation

so if the character rotates a bit, the camera gets rotated too, right

and now it wants to rotate even further

[rain tide]

Is that why?

So do I get rid of the camera part?

[heady iris]

If the camera is always trying to stay behind the character, then it will be impossible to walk towards the camera

and you'll just spin violently

see how it behaves with a fixed camera

[rain tide]

So, what do I do?

[rain tide]

Yeah.

[heady iris]

ideally, the camera shouldn't rotate when the player rotates

i'd suggest using Cinemachine for this

the Free Look Camera is a good fit

[rain tide]

I don't wanna use the FreeLook camera.

I need a fixed camera.

[heady iris]

so you don't want the camera to ever rotate?

or do you want it to always be exactly behind the player

[rain tide]

I want it to rotate with the player.

Ideally.

[heady iris]

if so, then you'll need to make it so that the player doesn't rotate when moving backwards

float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + Camera.main.transform.eulerAngles.y; you can probably just get rid of this entirely

[rain tide]

How do I just make it walk backwards?

[heady iris]

you don't have a horizontal component in there -- you do that rotation separately at the end

so all this can possibly do is try to rotate the character 180 degrees around

[rain tide]

What do I do here: ```cs

Vector3 moveDirection = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward * Speed * Time.deltaTime;

[heady iris]

I guess you can still compute the target angle

just don't use it to rotate the player

[rain tide]

Ok.

One sec.

It doesn't spin, but when I go backwards, it moves forward.

Wait, let me fix something.

[slim flower]

I have a question

I have this player script i made which is a mix of my stuff + changed carlson movement bc im lazy and other crap

but now i have this problem where it automaticly adds a character controller to the player object

and idk why

[heady iris]

it probably has a [RequiresComponent(typeof(CharacterController))] at the top

[slim flower]

i use a rigidbody movement so you could undrstand why this is a big problem

[slim flower]

nope it doesnt

[heady iris]

or it adds it somewhere in the script

you can just ctrl-f for CharacterController

[slim flower]

i did

nothing shows

[slim flower]

doesnt do that either

[leaden ice]

is the player a prefab?

[slim flower]

i can make a pastebin of the script to show

[slim flower]

yes

[leaden ice]

Does the prefab have a CC

when is the CC being added?

[slim flower]

https://pastebin.com/VxmzfnPt

[leaden ice]

and how does the player get into the scene? Is it there from the start? Is it spawned?

[slim flower]

it automaticly adds it when i reload the prefab

[leaden ice]

wdym by "reload the prefab"?

[slim flower]

even when i rememove it

but

when i disable it it stays disabled

[slim flower]

open a dif one and go back in

[leaden ice]

Ok so what components are on the prefab?

Can you show the inspector?

[slim flower]

yes

[heady iris]

well it's right there

albeit disabled

[slim flower]

yes

but i really want it gone

not just disabled

[leaden ice]

Check all of those scripts

[slim flower]

when i remeove the playercontroller script it doesnt auto add the CC

its only with the PlayerController script

[leaden ice]

I'd guess it might have something to do with mirror

something about how prefabs are registered with it perhaps

Unrelated but:
float mouseX = Input.GetAxis("Mouse X") * Time.fixedDeltaTime * sens * 50f;
You can remove 50f and fixedDeltaTime here, they just cancel each other out

fixedDeltaTime is 1/50

50 * 1/50 is just 1

[slim flower]

hahaah thank you

[heady iris]

yes, and mouse input should not be scaled by deltaTime, anyway

it is an absolute quantity

[slim flower]

so what do i do abt this issue

do i just search through mirror?

[leaden ice]

is there a way to register prefabs with mirror or something

i don't really know how it works

[slim flower]

yes

[heady iris]

i know you have to do that with Netcode for Game Objects, at least

but that's something else entirely

[slim flower]

i go through and register all prefabs in a resources/prefabs folder

thats not the exact dir but still you get my point

i dont get how to fix this though

[heady iris]

i would start by doing a sanity check

stick another random component on the prefab

see if that component shows up in game

[slim flower]

ok

[heady iris]

if it does, then it's probably not an issue with an old version of the prefab somehow getting instanced, or something

[slim flower]

yes it does

it does*

i fixed it

let me say the solution

for furture reference or similar issues

there are examples in mirror and in those exampeles there are premade scripts in games called the same as my own script, unity got confused betweent he scripts and saw the require conponent of the Character Controller and added it to my prefab.

basicly just delete the examples and change the name of the script fixes it

[low horizon]

how can i load an asset instantly when using addressables?

[leaden ice]

#📦┃addressables - you probably won't like the answer

[low horizon]

didnt knew there was a channel for that

[stone rock]

        // Create a static instance of InputManager that can be accessed from other scripts
        public static InputManager Instance { get; private set; }

        private void Awake()
        {
            // If an instance of InputManager already exists, destroy this duplicate instance
            if (Instance != null && Instance != this)
            {
                Debug.LogWarning("InputManager: Duplicate instance detected. Destroying the duplicate instance.");
                Destroy(gameObject);
            }
            else
            {
                // If there is no existing instance, set this as the instance
                Instance = this;
                // Make sure that this object persists across scenes
                DontDestroyOnLoad(gameObject);
            }
        }

Hello, i wanted to get some more clarification into using events. so i have this singleton class for input with the logic to set it up in the awake method, below is the code of another script that needs to subscribe to this script.

        private void OnEnable()
        {
            InputManager.Instance.InputGearUp += OnGearUp;
            InputManager.Instance.InputGearDown += OnGearDown;
        }

        private void OnDisable()
        {
            InputManager.Instance.InputGearUp -= OnGearUp;
            InputManager.Instance.InputGearDown -= OnGearDown;
        }

Based on the documentation i would assume that the awake method for sure is called before on enable but i get a null reference exception

or is it done like this where awake and onenable are called after each other for each object and not first all objects their awake methods and then the onenable method?

[leaden ice]

Awake will run before OnEnable on the same object

[leaden ice]

yes this

[stone rock]

is there a reason it's done like that?

[leaden ice]

Definitely

I assume Awake -> OnEnable is just part of the initialization process for an individual script

But seeing as Unity is closed source and we're not privy to the code or the people who made it, we can only speculate

[stone rock]

Yeah, i guess i'll use start for the subscribing then

or maybe just also do it in start

[leaden ice]

or use script execution order

[stone rock]

yeah, but i first want to do it without any orders just changing the code

onenable is not called a lot so i will add a check for it

[latent latch]

So I've been making some abilities that spiral out from the player and it's been working out, but I'm trying to figure out for this code:

                objectDirection = targetPosition - relativeTransform.position;
                objectDirection = Quaternion.Euler(0, 90, 0) * objectDirection;
                objectDirection = objectDirection.normalized;
                posChange = ability.StatDict[AbilityStatType.AbilitySpeed] * Time.deltaTime * objectDirection;```
Changing Eulers here to anything below 90 will spiral outward, and anything above 90 will spiral inward with the current code, but at exactly 90 I expect the projectiles to hold their position in a perfect circular motion, yet after a few rotations they do gradually fall off course.

Is there anything I'm missing here to prevent that?

[heady iris]

it could be down to accrued error

even if it's only slightly off, the errors will pile up over time

[latent latch]

I know there's some floating point accumulations, but it falls off so quickly.

[heady iris]

I wonder if you could compute the position parametrically

that might be the wrong word

you'd have a function that you just plug the lifetime of the projectile into and get a position

i'm not sure what the math would look like, though

[plucky karma]

Did you forget to normalize your direction before multiplying by the euler angles?

• Move objectDirection = objectDirection.normalized; above objectDirection = Quaternion.Euler(0,90,0) * objectDirection;

[latent latch]

Oh, also I manage to get the movearound method to work, I just had to multiply using the Rad2Degrees

object direction is initalized as vector3.forward

ah, yeah let me try that. I think I really tried everything like that so far

[heady iris]

hm, that could cause some errors, yeah

[latent latch]

Really it's closer to 89 degrees that really keeps it from going astray

Quaternion.AngleAxis(90, Vector3.up); behaves similar

[plucky karma]

You might have to perform some rounding logic to see if you are within 90 degree.

Otherwise, comparing exactly by precision value is unpredictable.

Are you calling this inside FixedUpdate()?

[latent latch]

Update

[heady iris]

oh! that's a good point

[plucky karma]

Try FixedUpdate() - Consider precaching Quaternion.Euler(0,90,0) since the value is immutable. No need to call it every update. 😄

private static Quaternion kCornerAngle = Quaternion.Euler(0,90,0);

[latent latch]

yeah ive got it cached, just typed what I'm doing ;p

[plucky karma]

Wait... untested code, not sure if I can call method inside static variable.

[quaint rock]

you can in that case

[plucky karma]

I think Update would be fine since you want to refresh position by frame dependent... Still, I think the problem is that you're going to be running into precision problem before your projectile could ever be perfect.

[latent latch]

Why exactly is MoveAround so pefect?

That doesn't seem to create any problems

[heady iris]

MoveAround?

[latent latch]

RotateAround*

[heady iris]

ah

RotateAround should just be doing trig

whilst you're moving the object in straight lines

now, in theory, those should be the same thing..

[latent latch]

                var lookDir = Vector3.Cross(targetPosition - transform.position, Vector3.up);

                transform.RotateAround(
                    sourceSpawnPosition,
                    transform.up,
                    Mathf.Rad2Deg * (speed / (ability.StorableSO.DistanceOffset / 2)) * Time.deltaTime);

                transform.rotation = Quaternion.LookRotation(lookDir, Vector3.up);```

works fine

I just kinda want the other thing to work with the spirals and the circular motion, but if it's just a precision thing then I guess it's not that big of a deal (don't want to deal with that right now)

Only problem is the look direction with this method is a little funky because by default it looks at the object it's rotating around

[heady iris]

yeah, it's annoying to have to have a special case

[plucky karma]

How are you making it orbit nearly 90 degree? What govern's the velocity?

[latent latch]

speed * Time.deltaTime * objectDirection

[plucky karma]

If you are controlling the vector, try considering adding weights to ensure the object will orbit perfectly, You can disable this feature by multiplying by magnitude value.

[heady iris]

what?

[latent latch]

I'll probably load up a blank project and play around with it more in case I've some hiccups somewhere in the code.

The SO page I mostly got the info from didn't really mention it working perfectly at 90, I'm just curious as to why it's not

[candid trench]

So i have the strangest bug happening to me right now.
I have a script with the OnDrawGizmosSelected() function defined.

Now, this does not work unless i go into the gizmos and tick the specific script first off and then on again.
And then it works for all of the gameobjects which has this script attached, but as soon as i switch to a gameobject, still with the same script attached, that is a child of another object then the gameobject i had selected when i turned the gizmo off and on again it stops working.

oh hang on a minute

do i need both
OnDrawGizmos()
AND
OnDrawGizmosSelected()
in my script for the selected version to work? o.O

[quaint rock]

the component has to be exapended

and the object has to be selected

if you only want it for selected OnDrawGizmos is not needed

[candid trench]

exapended?

[quaint rock]

if the component that has the OnDrawGizmosSelected on it in the inspector is not expanded out so you can see everything it will not display

[candid trench]

ah, well i tried that, didnt do anything really.

But adding OnDrawGismoz() in the script, just empty, worked

[quaint rock]

weird what is the logic

sounds like it could be a bug, might see if there is a new minor update for your unity version

[plucky karma]

Your component must be fully expanded for OnDrawGizmos()/OnDrawGizmosSelected() to work. Are you sure that's how you spell your method?

[mighty granite]

https://youtu.be/CmU5-v-v1Qo

This is a much better way of doing it. Line renderer just isn't made for complex UI things.

[plucky karma]

I hated how there isn't a UI Line Renderer 😦

[mighty granite]

Nope

[prime pelican]

hi, i have a question

I am trying to create a hud using ui toolkit
I created a text label, but I am not sure how to access it in my script

[vagrant blade]

#🧰┃ui-toolkit

[keen warren]

Looking for the best approach.

I have a quest system, one of the goals is to talk to an NPC. I listen for the NPCInteractEvent to achieve this but how I implement it has a side effect. The interaction event is fired before I deal with the dialogue then I check the goals status so I can display relevant dialogue but of course, side effect, quest gets completed before the goal check.

How would it be better to handle this? For added context, dialogue is handled via nodes. In a sense, the event would be better fired after interaction has finished but that may not always be applicable. Maybe there should be two events (interact start and end)? I'm not sure.

[cosmic rain]

Maybe a dialogue completion should be a separate event entirely?

Only completing quests on interaction sounds very limited.

[keen warren]

mmm actually true, it prevents dialogue where one option progresses to the next goal and the other doesn't.

although that may be better handled in the node graph for said npc or what have you, not too sure but you're right

[sinful pivot]

Hello everyone,

I'm having some trouble with my Scriptable Object in Unity. I'm trying to use it to store data for my game, whenever I enter play mode or restart Unity, the data is lost.

I am trying to create a Scriptable Object that allows me to easily specify the boundary rules for a procedural generation project. Here are my two scripts: the main script and the editor.

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Tilemaps;
 
[CreateAssetMenu(fileName = "New Prototype", menuName = "Prototype")]
public class Prototype : ScriptableObject
{
    public Tile tile;
 
    private Dictionary<int, bool[]> connections = new Dictionary<int, bool[]>();
 
    public bool[] GetConnections(int id)
    {
        if (!connections.ContainsKey(id))
        {
            connections[id] = new bool[4];
        }
 
        return connections[id];
    }
}

using System.Linq;
using UnityEditor;
using UnityEngine;
 
[CustomEditor(typeof(Prototype))]
public class PrototypeEditor : Editor
{
    private Prototype prototype;
 
    private void OnEnable()
    {
        prototype = (Prototype) target;
    }
 
    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
 
        Prototype[] prototypes = AssetDatabase.FindAssets("t:Prototype")
            .Select(guid => AssetDatabase.LoadAssetAtPath<Prototype>(AssetDatabase.GUIDToAssetPath(guid)))
            .ToArray();
 
        EditorGUILayout.BeginHorizontal();
        EditorGUILayout.LabelField("", GUILayout.Width(EditorGUIUtility.labelWidth - 4f));
 
        EditorGUILayout.LabelField("Right", GUILayout.Width(40f));
        EditorGUILayout.LabelField("Left", GUILayout.Width(40f));
        EditorGUILayout.LabelField("Up", GUILayout.Width(40f));
        EditorGUILayout.LabelField("Down", GUILayout.Width(40f));
 
        EditorGUILayout.EndHorizontal();
 
        foreach (var p in prototypes)
        {
            EditorGUILayout.BeginHorizontal();
 
            EditorGUILayout.LabelField(p.name, GUILayout.Width(EditorGUIUtility.labelWidth - 4f));
 
            bool[] connections = prototype.GetConnections(p.GetInstanceID());
 
            connections[0] = EditorGUILayout.Toggle(connections[0], GUILayout.Width(40f));
            connections[1] = EditorGUILayout.Toggle(connections[1], GUILayout.Width(40f));
            connections[2] = EditorGUILayout.Toggle(connections[2], GUILayout.Width(40f));
            connections[3] = EditorGUILayout.Toggle(connections[3], GUILayout.Width(40f));
 
            EditorGUILayout.EndHorizontal();
        }
    }

This results in the desired setup seen below.

I am able to check the boxes and see the updates, but the data is lost if I enter play mode or restart unity.

I've tried calling AssetDatabase.SaveAssets(), SetDirty(), and trying various methods to serialize the data, but nothing is working.

Does anyone know how I can fix this issue? Any help would be greatly appreciated.

[prisma birch]

Is there a way to correctly add a component using OnValidate? It's working but I'm getting this warning: SendMessage cannot be called during Awake, CheckConsistency, or OnValidate (GameObject: OnDidAddComponent)

Hoping to avoid a custom inspector

[prisma birch]

Hmm, looks like you can use async await to get around it

[atomic bone]

I'm trying to use

[Preserve]

to prevent reflection code from stripping but it is not working

all the reflection code seems to be still "missing" after the android build

it's IL2CPP

[cosmic rain]

I'm not sure reflection works in IL2CPP builds.

Since it's part of the .net runtime afaik.

According to the docs some of it works.🤔

I guess it needs to be checked on case by case basis.

[amber haven]

Not really, that way is difficult to customize, overly complex and built from scratch. My workaround way is easily customizable and uses built in features rather than writing a line render engine from scratch.

Plus I highly doubt that it would work overtop of a 3d camera which is the whole reason for a workaround anyway.

He seems to be making it for 2d, or for 3d use but on a separate camera which wouldn't work for me.

[swift falcon]

        if(deadBodies.Count >= maxDeadBodyCount)
        {
            for (int i = 0; i < batchRemoveCount; i++)
            {
                deadBodies.Remove(deadBodies[i].gameObject);
            }
        }

Would Running this statement in Update be a heavy task? I am unsure how fast Lists are

[buoyant crane]

It’s won’t be heavy until the actual removal occurs. You should use a queue rather than a list

[swift falcon]

ill look into those rn

[swift falcon]

            for (int i = 0; i < batchRemoveCount; i++)
            {
                deadBodies.Dequeue();
            }

Does this look right?
Since: "Returns an item from the beginning of the queue and removes it from the queue."

[buoyant crane]

yep

[swift falcon]

Alright great, I cant see Queues in the inspector sadly though

[buoyant crane]

I wish it worked with more data structures

[spare wing]

Hi

any Visual Studios user here?

https://marketplace.visualstudio.com/items?itemName=jefferson-pires.VisualChatGPTStudio

this is very useful extension for you if you use Visual studios

I hope its Helpful

[swift falcon]

@buoyant crane I cannot seem to get game objects from the Queue, cannot find much on google, I may need to just use Lists? (I need to destroy gameobjects from that queue)

[buoyant crane]

When you call Dequeue it returns the GameObject as well

So you could do Destroy(bodies.Dequeue());

[swift falcon]

Bruh I tried that the first time and it didnt work, now it does lol

Thanks

Once again

Now I can happily remove dead bodies

[atomic bone]

well of course it works, otherwise there won't be any Google Play anymore

it's just when you strip code at the highest level, it will be gone

[latent latch]

What's usually the more performative way to prevent multiple instances of damage to an entity in a time frame? Having a lookup table with IDs and with a previous time is the easy solution, but let's think about hordes of enemies where you've multiple abilities at your disposal.

[real anvil]

Is it really a performance problem?

Have you benchmarked your current implementation and seen it be an actual problem?

[latent latch]

I've yet to really benchmark what I've got to the fullest, but this is more of a general question for its implementation. At the moment each of my abilities does contain a hashset which keeps track of previous hit enemies, but I'm getting to the point where I'm slinging many of those abilities all at once into waves of enemies.

[real anvil]

Even if theres 1000 enemies, keeping track of them is nothing

A hash table lookup is one of the cheapest ways to do this kind of tracking

[pearl trench]

how can I spawn objects randomly around the scene? I don't want them to spawn inside other objects

[potent sleet]

pick random position and spawn

[pearl trench]

yeah but how do I make sure it doesn't spawn in other objects?

[potent sleet]

something like physics.checkbox ?

if blocked , spawn elsewhere

[pearl trench]

ok thank you

[steady moat]

Unity does not serialize dictionary which is why the values are lost whenever you quit the application.

[modern meteor]

hello

i have a Country class and a Tile class

there's going to be a static array/class of Tile instances

and a static array/class of Country instances

now i want each tile to store which country it belongs to

and each country to store a list of tiles it has

usually i use pointers, but this is C#

any ideas?

references wont work

public class Tile
{
    public int x;
    public int y;
    public Biome biome;
    public Country* country; // cant do this
}```

also, in the future i want to have a function that would look kind of like this: ```CS
public void DrawName(List<Tile*>, string name);

it also has pointers

[split wedge]

It's not really recommended to use pointers in C#, but if you really want to I suggest reading this for a bit:
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/unsafe-code

[modern meteor]

ah, thanks

there's no way that the pointer will be used after dereferenced btw (it's a pointer to member of static class)

oh, if Country is a managed type

what do i do?

[quartz folio]

Classes are reference types in C#, there is no need for a pointer

[modern meteor]

wait really?

i'm pretty used to C and C++(was working on something else) so it's pretty confusing

[quartz folio]

Classes are reference types, structs are value types. Classes are allocated on the heap, and structs are allocated on the stack if they're defined in a small enough scope that allows for it

[modern meteor]

that's awesome

thanks

way easier now

wait, what about if you make an instance of a class locally

and then you call a method with it, then the method stores it somewhere else

the class wont be dereferenced right? because it's on the heap

so it's safe

[atomic bone]

won't, and that's the whole point of a managed language like C# comparing to unmanaged ones like c, cpp,
so it's forced you have to use "new" to create class instance in C#,
downside is due to this nature, you cannot have const correctness in C#

[quartz folio]

If anything references the class it will not be deallocated

You also have to mind clearing references to avoid leaks, which can be tricky at times with stuff like closures

[modern meteor]

really nice

thanks 🙂

[atomic bone]

i really wonder can you somehow impl const correctness in C# tho

i miss that thing so much

but then again, that's like just against the whole point of C#

idk

Anyone know how to make a Pathfinding Agent with Aron's A* Pathfinding stop getting stuck at corners? I am just at a lost.
This is on a 2D Tilemap

[heady iris]

I'm guessing the problem is with how you move the agent, rather than with how the path is calculated (A*)

[candid zenith]

I just have A* move the agent for me, I guess? Default settings, except for Pick Next Waypoint Dist which was lowered due to the Agent trying to go through walls.

[normal arch]

so i have to make a change to my project so that all things that have sprite renderers in my project have to have them be a separate child game object from the parent object and i have to change all the animations so that they are on the right sprite renderer. Is there a quicker way to do this because it's becoming very tedious

[heady iris]

You can edit the path for an animation channel directly. That might help if you’re making the same change for every single channel

I’ve done that for my VRC avatar when moving parts around

[normal arch]

how would you do that

[heady iris]

so I made an animation that controls the scale of the "Path" object

if I hit Enter (on macos; it's probably F2 on windows), I can edit the target of that channel

[dense canyon]

How can I play an audio file from disk? All google posts I've found point to a WWW class which is deprecated.

[leaden ice]

for URI do I pass in the raw filepath or do i need to add something else?

[heady iris]

I would expect to need to use the file:// protocol

[halcyon gull]

Just 3 months ago I created a game using Unity Mediation package and got a good grasp of how to write code. Now I wrote similar code for my new project just to find out that Unity swapped that Mediation package with some LevelPlay that works with IronSource.

Why does this change so often and should I expect LevelPlay to change again anytime soon?

[fathom totem]

The inputs in the new input system, what are their refresh rate? (Such as when using Pass-Through and ReadValue<>)

Would ReadValue return the last input registered from the hardware polling rate, the input from the last frame update, or from the last physics update?

[leaden ice]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.1/manual/Settings.html#update-mode

[fathom totem]

Ah, thank you, don't know why I couldn't find that

[wary wagon]

Hey, i want to draw a minimap of my game. Basically i just want to draw some rectangles and layout of the map.
I am thinking of using Texture2D .. however this is reaally slow, i want to avoid drawing every pixel ( especially wasting CPU filling all the image with transparent pixels).

Is there a better way ?

[leaden ice]

Typical approach to a minimap is a camera rendering to a RenderTexture, drawn in the UI with RawImage

[static matrix]

is it possible to make a button do something different on rclick rather than normal click

[leaden ice]

yep

[static matrix]

how

[leaden ice]

Use IPointerClickHandler instead of the button on click

or event trigger

and the pointer event data contains info about which button it was

[wary wagon]

ya i saw that, i dont want to do it because i want my map to be transparent over the screen ( like diablo 1)

[static matrix]

uuuuuuuuuuuuuuugh Im too tired to learn something new haha

Imma make a smaller button for dropping

sorry

ill get back to it

[heady iris]

one thing about filling pixels

you can set many pixels at once with SetPixels

this is reasonably fast

[wary wagon]

Im gonna prepare a Color32[] buffer full of transparent and .. yea.. do setPixels

[leaden ice]

hey you asked lol

[static matrix]

yeah, sorry i didn't know if it was possible using the normal button

its cool

my b honestly

[wary wagon]

Basically lol i want to use Gizmos to create my minimap xD

[heady iris]

aren't gizmos editor-only

[wary wagon]

Ya, but i want non-editor gimzos ;D

[olive shore]

im sorry, but has anyone got any know how on this?

Building Library\Bee\artifacts\Android\d8kzr\libil2cpp.so failed with output:
ld.lld: error: undefined symbol: GADUGetAdErrorCode

[static matrix]

its an error alright

[wary wagon]

so mm what would be the best to mimick gizmos outside editor 🤔

[jagged latch]

i have this code to automatically make a PolygonCollider2D in the shape of a circle sector, as such, but i would like some way to mask the sprite programmatically so that what you see in the collider is the only bit that's shown. how would i go about doing this? (it doesn't have to use the collider, but just some way to mask a sprite in a sector/arc with a customisable angle)

[static matrix]

scratch pen ofc
(Ill leave now)

[wary wagon]

scratch pen ? 😮

[static matrix]

nah its a scratch thing

the funny orange cat

imma let you be now, back to the backrooms

[heady iris]

Scratch support for unity when?

💥

visual scripting 2, baby!

[wary wagon]

🤔 maybe i should just access opengl low level stuff so i can draw fast triangles on the screen ? that will be faster than bothering with texturing the minimap

[leaden ice]

that can still be done with this technique

just make sure the minimap camera only renders obstacles etc and doesn't render the ground

[wary wagon]

The issue is that i mask the rooms on which my player is not ( i have a tileset that draws black tiles ) .. so the minimap will be black ?

[leaden ice]

just don't draw that tilemap in the minimap camera

[wary wagon]

Ahh i can do that ? fun

https://gyazo.com/8e5b1db1a6ccb05e8554cb165124db58

[leaden ice]

yes using culling masks

[wary wagon]

ok ! going to check this

Ideally i just want to render the walls

mm now i need a way for the camera to not render what the player hasnt visited yet .. hard ;D

[heady iris]

someone in #💻┃code-beginner was just doing that :p

i'm guessing you want to do this per-room, though?

slap a trigger on the room that the player interacts with

[wary wagon]

basically .. i want to show the full layout of a dungeon for the room the player has visited.

haha now im thinking to have a tileset that is rendered only on the minimap.. i can do this 😄

[heady iris]

It might be slightly harder if you want the rooms to always appear in the main camera, but only get put on the minimap if you've actually been in them

[wary wagon]

in the main camera i dont want to show the rooms in which the player is not

For gameplay ( i expect monsters to ambush the player) and perf reasons

[worldly hull]

maybe u can do some tricks on the culling mask

[wary wagon]

yeah i will do it

[timid crater]

Good afternoon! is there a way to read an element from the queue without dequeuing(removing the element)?

[vagrant blade]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.queue.peek?view=net-7.0

[timid crater]

I tried Dequeue(); before but it removes the element from the queue

[heady iris]

peek, right?

yeah

[timid crater]

Ohhh that what I was looking for, thanks!!

[jolly sparrow]

Can anyone help me out? Can't figure out to move an object move perpendicularly to my movement when i collide with it, on 2D

[heady iris]

do you mean you want it to get pushed directly way from the player?

[jolly sparrow]

like if i move into an object from the left side it will be pushed vertically to the top or or down, etc

[heady iris]

ah, okay, so actually perpendicularly

i wasn't sure if you meant something else :p

[jolly sparrow]

i edit the sentence, i missed a word when i was typing

[heady iris]

well, let's see

so you need to find a vector that's perpendicular to the player's movement vector

Vector3.Cross will do the trick

The cross product can best be visualized as

A is gonna be your movement vector

B is the "forward" vector (the one going into the screen)

and then AxB will be the result

Vector3.Cross(rb.velocity, Vector3.forward);

alternatively, you could rotate the velocity vector

Quaternion.Euler(0, 0, 90) * rb.velocity;

I think that one make sit more obvious which way it will go

it's a 90-degree rotation

[fervent furnace]

https://en.wikipedia.org/wiki/Rotation_matrix
maybe this is helpful but there already is a built in function

and cross product is defined in 3d space, but you can treat z is 0

[heady iris]

yes, there's no need to figure out transform matrices here :p

[heady iris]

yeah, it's 3D only

fortunately, what we want is the cross with the (0,0,1) vector

[wide verge]

Anyone know how to save an int value (to read from on next play) from another script?

[heady iris]

on next play meaning "the next time the game runs"?

[jolly sparrow]

    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            Vector2 pushDirection;

            if (Mathf.Abs(movementVector.x) > Mathf.Abs(movementVector.y))
            {
                // If moving mostly horizontally, push enemy up/down
                Vector3 perpVector = Vector3.Cross(rb.velocity, Vector3.forward);
                pushDirection = new Vector2(perpVector.x, perpVector.y).normalized;
                Debug.LogError("Player Moving Horizontally:" + pushDirection);
            }
            else
            {
                // If moving mostly vertically, push enemy left/right
                Vector3 perpVector = Vector3.Cross(rb.velocity, Vector3.forward);
                pushDirection = new Vector2(perpVector.x, perpVector.y).normalized;
                Debug.LogError("Player Moving Vertically:" + pushDirection);
            }

            collision.gameObject.GetComponent<Rigidbody2D>().velocity = pushDirection * pushForce;

        }
    }``` @heady iris changed my previous code and ended up with this, but the object still wont be pushed away

[wide verge]

yes

[heady iris]

note that the conditional doesn't do anything here, since they both have the same code in them!

Do you want it to snap to the axes?

i.e. it only goes up, right, down, and left

[fiery geyser]

how can i check if two colliders are intersecting, 1 box collider and 1 non convex mesh collider

[heady iris]

It's relatively annoying to directly ask if two colliders are touching in 3D physics

[jolly sparrow]

just the 4 directions, you say the if doesnt do anything there then?

[heady iris]

I'd just use OnCollisionEnter and OnCollisionExit to keep track

[heady iris]

well, yeah, both blocks of code are identical!

[fiery geyser]

idk if it works

i need to check when it spawns

[heady iris]

ok, hang on

what is the usecase?

[fiery geyser]

i have 2 structures, and i need to check when another spawns, if it is intersecting one of them

[jolly sparrow]

private void OnCollisionStay2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            Vector3 perpVector = Vector3.Cross(rb.velocity, Vector3.forward);
            Vector2 pushDirection = new Vector2(perpVector.x, perpVector.y).normalized;
            Debug.Log("Direction:" + pushDirection);
            
            collision.gameObject.GetComponent<Rigidbody2D>().velocity = pushDirection * pushForce;
        }
    }
```oh yeah, but still, the object **isn't** being pushed away perpendicularly

[heady iris]

you'll get an OnCollisionEnter call

since you said one is a box, though

you can just use Physics.OverlapBox to ask for colliders in an area

[fiery geyser]

even if i don't have the reference of the other two?

[heady iris]

right, it just asks if anything (on the specified layers) is in there

[fiery geyser]

oh ok

let me try

oh wait

i did try the overlap box

Physics.OverlapBoxNonAlloc(bounds.center, bounds.extents, new Collider[] {}, Quaternion.identity)

but didn't work

[heady iris]

if you don't understand what NonAlloc means, do not use it

just use Physics.OverlapBox and loop over the array of colliders

[fiery geyser]

it was suggested by Rider

[heady iris]

Rider can suggest many, many things, but most of them are the wrong choice :p

[wide verge]

Anyone know how to save an int value (to read when the game is next ran) from another script?

[fiery geyser]

oh ok

[heady iris]

[heady iris]

again

use PlayerPrefs.

https://docs.unity3d.com/ScriptReference/PlayerPrefs.html

[gray vessel]

Is there any way to change a component to an inherited version of itself? I had a bug script, and I want to retain the inspector properties, of which there are many, when changing it to an altered, inherited version. Previously, you could change the Script field in debug mode, but they seem to have blocked that off

[wide verge]

I know they exsist but before i save the data i need to get the data from the other script (stopwatch script). How do i do that?

[heady iris]

Yes.

oh, I see

I thought you were asking about having the other script get the saved value

well, you have a reference to the stopwatch script, right?

if so, you can access any public field of the stopwatch script

[heady iris]

If you don't , add a field to the first script, public Stopwatch stopwatch; (or whatever you called the stopwatch script

and drag the stopwatch object into the resulting field

[wide verge]

Alr thx.

[fiery geyser]

thx, it was the NonAlloc

[heady iris]

if you are curious

NonAlloc means that the method does not allocate its own memory. Instead, you give it an array you made yourself.

[fiery geyser]

ohhhh

that's why

[heady iris]

This means that it's not creating and destroying an array every time you use it, which can matter if you're worried about creating too much garbage

i.e. memory that was allocated and then thrown out

For example, I use it when I just need to check if something is in an area

and I give it a one-element array

I would only worry about that if you're doing this many many times per second

if it's just for when an entity spawns, and you spawn a sane number of them, don't even bother

[fiery geyser]

depends on how fast the player is moving, but shouldn't spawn a lot of them

and just intersect max 4 things

[jolly sparrow]

private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            Vector3 perpVector = Vector3.Cross(rb.velocity, Vector3.forward);
            Vector2 pushDirection = new Vector2(perpVector.x, perpVector.y).normalized;
            Debug.Log("Direction:" + pushDirection);
            
            collision.gameObject.GetComponent<Rigidbody2D>().velocity = pushDirection * pushForce;
        }
    }
``` @heady iris its working now but i have 2 problems, the object will only be pushed away in a clockwise rotation and it is only pushed away if the Enemy Object isn't moving so my script of the Enemy Object Movement with ```csharp
private void FixedUpdate()
    {
        Vector3 direction = (player.position - transform.position).normalized;
        rb.velocity = direction * velocity;
    }``` on the Enemy object to make it follow me has to be disabled for to Object to be able to be pushed away

[heady iris]

well, yeah, you're overwriting the velocity on every fixed update

perhaps the enemy should either get "stunned" and not move after getting hit

or it should gradually adjust the rb's velocity

[jolly sparrow]

what about the clockwise rotation

[heady iris]

maybe the enemy is pushing into the player and turning as a result

you can check something on the Rigidbody component to freeze rotation

that might be useful

[jolly sparrow]

Sorry, should have explained better, what i mean is that the object is being pushed away in a clockwise direction around the Player Object, so if i collide with it from the left side he will be pushed down, etc
from above -» to the left side
from the right -» up
from under -» right

[heady iris]

ah

isn't that what you wanted?

[jolly sparrow]

The idea is that if im for example, surrounded by enemies and i want to pass through them, they will be pushed away perpendicularly to my direction so that i can move through, and it would be weird if it only worked on a clockwise direction like this

[heady iris]

so you want them to get pushed up or down depending on whether you're above or below their center?

and only get pushed in the cardinal directions?

[jolly sparrow]

if they are to my sides they will be pushed down or up, if they are up or down they will be pushed to the sides, depending on which direction i try to pass through

it would also have to work in diagonal directions i guess so i can move that way, but baby steps, was trying to get the other directions right first

@heady iris sent you a clip on dm

Any thoughts on how to implement floating unit icons as in Warno? So that even if units overlap, the icons will never overlap?

[heady iris]

i think i ran into this before...

hmm

you could do it with Actual Physics

with 2D rigidbodies (with some serious limits on how fast they can move :p )

[swift falcon]

how so? sounds interesting

just standard collision behaviors would constantly jitter back and forth no?

[sleek bough]

#archived-networking

And #854851968446365696 how to ask questions

[gilded bramble]

sorry

[heady iris]

you'd want them to be very heavily smoothed

[swift falcon]

is there a smoothing variable?

[heady iris]

actually, one thing -- are those units part of a squad of some sort?

i.e. they're always together

that might make it easier

[swift falcon]

I mean, no, mechanically it's just single units

[heady iris]

but you'd still want to have the icons stick to the individual units when you zoom in close enough..

[sleek bough]

You can feed units on the screen to a UI which will project world to screen position. And if their rectangles overlap to collect them into UI grid which will handle a lot for you.

[heady iris]

very high drag, maybe

[heady iris]

That was the other thought I had

[swift falcon]

yeah, abstract but probably true

UI grid specifically seems nice

[mint estuary]

Hey ppl, on Unity if i have two Monobehaviors object, referencing the same instance of another gameobject

ClassTest1

can happen that Before ClassTest1 receive GetValue(), ClassTest2 have it changed too?

unity is single-threaded

[leaden ice]

Your question is very hard to understand but yes if you have two references to the same object, you can see the changes made to it in both places. You're looking at the same object after all.

[heady iris]

they're asking if both scripts could call SetValue before one of them calls GetValue

[mint estuary]

Exacly

[heady iris]

this cannot happen; the scripts on the objects will get updated in sequence

even if you spawn off some coroutines and have them mess with the value, they will also run in sequence

[mint estuary]

oh, ok them, thank you @heady iris !

@leaden ice thanks too

[fiery geyser]

why gameObject.transform.rotation.y is returning 0.7018 when the rotation is 90 on the inspector?

[simple egret]

Because .rotation is a Quaternion value, something that represents a rotation in a very abstract way

4 float values, ranged from -1 to 1

[fiery geyser]

so, how do i get the real rotation?

[leaden ice]

sounds about right

[simple egret]

.eulerAngles

[fiery geyser]

oh ok

[leaden ice]

that is the real rotation. use euler angles if you want the euler representation

[simple egret]

That spits out angles in degrees

[leaden ice]

it's generally not a good idea to read euler angles back from a Transform in code except for display purposes though.

[charred geyser]

This might seem dumb, but I'm having problems with rotating in 2d to the mouse. So, how to do that?

[fiery geyser]

i just need multiples of 90

btw, is there a way to make float operations more precise?

[leaden ice]

myObject.transform.right = directionToMouse;

[leaden ice]

it's unlikely you need it.

[elder otter]

Sort of. You can use double but Unity doesn't use it internally so it has limited use

[charred geyser]

I did that, but my character just gets its front to that direction, making it look paper thin

[heady iris]

i completely forgot you could do this

[leaden ice]

you did it wrong

show your code

sounds like you did forward not right or something

or directionToMouse was calculated improperly

[charred geyser]

Correct, but it was something else

[leaden ice]

e.g. with a nonzero z value

[charred geyser]

Turns out I used transform rather than render.transform (render is an object for the sprites)

How do I make objects not collide with objects of a certain layer?

I already did the layer thing, but it didn't work

[leaden ice]

Layer based collisions

https://docs.unity3d.com/Manual/LayerBasedCollision.html

[charred geyser]

I did that

[leaden ice]

you must have done it incorrectly

show what you tried

also make sure you used 2D physics settings if you're using 2D physics

[leaden ice]

Is this 2D or 3D?

[charred geyser]

Yeah, that was the problem

Thank you

Hello, not sure if this is the right channel, but I'm having a bit of a problem with Mirror and Networking inside my project.
I'm using a Steam based P2P system, only two players. Each player has a parent object which gets filled with Instantiated prefabs.
Now i want a function, that "copies eachothers prefabs" into our parent, so our unique prefab list merges on both clients.
How should I get started with this?

[fathom patrol]

Any idea why my Serializefield area isnt popping up?

Code:

using System.Collections;

    public Enemy GetRandomWildEnemy()
    {
        return wildEnemys[Random.Range(0, wildEnemys.Count)];
    }
}

I have no errors so I dont understand why its not popping up

How is Enemy defined?

Is it serializable?

I want to grab an entire canvas mainly so I can set .enabled to true and false
putting the canvas in a GameObject doesnt seem to work so what variable do I put it in

[leaden ice]

Canvas

if that gives you an error message - read the message as it has important information for you, and check what auto-fix suggestions your IDE has for you.

[sonic zinc]

it sort of works, it unpauses but it cant pause @leaden ice

[leaden ice]

well yeah

look at your code

shouldn't that if be an else if?

[sonic zinc]

am I missing something obvious

[leaden ice]

yes

the second if will run right after the first one

they're independent

[sonic zinc]

oh thanks

I never use else if and end up using 2 ifs

it works now

[leaden ice]

better code for this:

void Update() {
  if (Input.GetKeyDown(KeyCode.P)) {
    paused = !paused;
    Time.timeScale = paused ? 0 : 1;
    uiPause.enabled = paused;
  }
}```

no need for the duplicated code.

[sonic zinc]

Time.timeScale = paused ? 0 : 1; //how does this line work exactly

@leaden ice

[leaden ice]

it sets time scale to 0 if paused is true, 1 otherwise

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/conditional-operator

[sonic zinc]

alright thanks for all of the help

[sonic zinc]

I just put it in and for some reason this doesnt bring up the UI, the game still pauses but the UI doesnt get enabled

I have implemented a FSM for walking, jumping, attacking etc where all are different states. Is this a bad approach for game design as most of the time things are overlapping? The user should not notice these, after all

[sonic zinc]

I got it to work now

what I did was enable the canvas in my inspector but disable on void start

Greetings,
I have a editor window script that references a TextAsset. I want to open the TextAsset at a specific line-number in vscode. I'm using the method AssetDatabase.OpenAsset(). It does work properly for .txt files.
However, I have created a custom file-type ".aljs". I created a ScriptImporter that imports those files as TextAssets. I have a custom vscode extension for this file-type for syntax highlighting. AssetDatabase.OpenAsset(). opens the correct file, but it does not jump to the correct line. The documentation (https://docs.unity3d.com/ScriptReference/AssetDatabase.OpenAsset.html) "If it is a text file, lineNumber and columnNumber instructs the text editor to go to that line and column."
Is there a way to make it work for my custom file-type?
I have a workaround in place, but it's kinda bad. It starts a process before which opens a console window for short and it's kinda slow.

string filePath = AssetDatabase.GetAssetPath(textAsset);
string fullPath = Application.dataPath + filePath.Substring("Assets".Length);
System.Diagnostics.Process.Start("code", "-g \"" + fullPath.Replace("\\", "/") + "\":" + 15);
AssetDatabase.OpenAsset(textAsset);

Does someone know how to make it work without having to start an additional process?

Kind regards.

I have a "sheath" animation that my character is engaging in here, but this involves reparenting the sword from the character's hand to their back. the animation runs in a coroutine while the reparenting is done imperatively, i'd just like to know what the most straight-forward/idiomatic way to do the reparenting at the right moment in the animation would entail. should i just try and figure out exactly how many (milli)seconds into the animation is the right time for the reparenting to occur and then do the reparenting in a coroutine that waits that long before starting?

[severe marsh]

animation events seem like the best option in my opinion, their purpose is to do exactly that: execute code at a specific time during an animation

So i'm trying to use a tilemap for the in game map, for some reason some of the white edges dissappear in game

notice in the top right how the rectangle doesnt have the bottom edge like in the editor

[leaden ice]

are you using a pixel perfect camera?

[marble halo]

no

that might be why

[leaden ice]

you should be

[marble halo]

btw is using a tilemap for a map a good idea

I thought of doing it cause it would make it easier to make levels

why cant the pixel perfect camera rotate down?

[marble halo]

it didnt do anything?

Is it cause im in 3d?

[leaden ice]

wdym by "in 3d"?

you should be using an orthographic projection on your camera if it's a 2D game, if that's what you mean

[marble halo]

my game is 3d also it says that render texture doesnt support the pixel perfect camera

I'm getting weird stuttering with Cinemachine. I've got some camera math that updates in FixedUpdate and then interpolates in LateUpdate, which is important for the kind of high-speed type of game that I'm working on.

This works perfectly in raw code, but every time I try to get Cinemachine to run it, even when I'm updating all the data manually. I've tried switching the update method and calling ManualUpdate from within LateUpdate.
Something about Cinemachine's internals or the MutateState function must be failing to apply the camera transform properly. Does anyone know what could be causing it?
