haha

yeah Odin makes dealing with serialized interfaces a lot easier

I just cant go back to normal unity without it

at very least NaughtAttributes has to be in the project

[undone coral]

the question is: why.

why have IFireRate at all

you can use an abstract base class inheriting from behaviour. then attach it to a gun prefab

[humble loom]

if you read the prior convesation, obviously IFireRate is very simplistic, and not necessary if you just want a float, but having compositional design of something and each component "socket" having generic behavior, and being able to compose that from the script level is what the purpose is

[undone coral]

you already have composition, it's a prefab

[humble loom]

yeah you solved it

interfaces serve literally no purpose in programming

[undone coral]

when using the editor for storing data, they get in the way

Anyone know a good resource for learning about Rotation matrixes (or matrices?)?
Trying to learn how to rotate 3D vectors mathematically using linear algebra

[woven kettle]

hey is it possible to make a Raycast continue if it hit a certain target ?
for example If the raycast hit a player, i want it do some impact animations on the hitpoint but also keep going, what is the best way to do that ?

[fresh salmon]

RaycastAll, order by distance, loop over the results and break if you deem that something is not traversable

[sly grove]

Use a loop. Fire a new raycast from the hit point continuing in the same direction.

You could also just do a RaycastAll and do something for each hit

[fresh salmon]

I am officially invisible it seems

(note that a sorting is required as RaycastAll results are in an undefined order)

[sly grove]

Only if order matters for this use case 😛

[woven kettle]

Something like that ?

public Transform source;
RaycastHit hit;
if (Physics.Raycast(source.position, source.transform.up, out hit, maxRange))
{
   if(hit.transform.GetComponent<Player>())
   {
      // do some hit impact and health damage to the first player 
       RaycastHit hit2;
       if (Physics.Raycast(hit.transform.position, hit.transform.up, out hit2, 500f))
       {
          if(hit2.transform.GetComponent<Player>())
          {
              // do some hit impact and health damage to the SECOND player 
          }
       }
   }  
}

I'm not sure if hit.transform.up would be the right direction; not sure if it would be the same as source.transform.up

[fresh salmon]

If your limit is 2, then yeah, otherwise you might need iteration or recursion

[sly grove]

Using a loop if you want to do it more than twice

[fresh salmon]

lol I am indeed invisible

[sly grove]

and no it'd be the same direction vector

[fresh salmon]

Or blocked

Not blocked, reactions pass

As for the direction, I would store the original direction in a variable, and pass it for each new raycast

That way it can easily be adapted if you use a loop or recursive methods

[woven kettle]

ok thank you guys!! @sly grove @fresh salmon
I had the similar mind at the beginning but I was skeptical as i'm not an expert and maybe there is a better way to do it

[sly grove]

if the damage and impact stuff is the same for each player it hits - it looks like you can just do a RaycastAll and iterate over all the hits, applying the same impact and damage for each one. No ordering is required.

[woven kettle]

Very interesting idea!!, Thank you!
but yea I'd need the order as the damage should decrese after the first impact 🙂

[sour marlin]

How efficient is the IPointerDownHandler & IPointerUpHandler When there's atleast 80+ objects that implement those interfaces? Is it less efficient than just getting where the mouse was clicked and mathing out if that point is on an ui element?

My scenario is that I have a grid of tiles that all need to be "clickable" but that they need to know about when the pointer is down on them or up.

[sly grove]

very efficient.

[sour marlin]

More efficient than just doing the calculations of where the mouse was clicked myself?

[sly grove]

Hard to say.

You could do the calculations for a simple 2D grid very fast compared to the general purpose interval-tree or quad-tree they probably use. but Unity's code is also running on the native C++ side so it has that advantage.

The benefits of working within the event system are many though, so I'd just stick with IPointerDownHandler etc...

if you notice a performance issue, you can revisit it.

[sour marlin]

Right, thanks a bunch!

[turbid mural]

Does anyone here uses Ryan Hipple approach for Game Architecture using ScriptableObjects the same way?

[astral python]

Anyone ? Can't make it work correctly. I've probably made some mistakes while porting this to C# but can't figure it out

[onyx gulch]

hey guys i tried to run a unity x86 (not x86 64) build headless server on a windows 2003 server but got .exe is not a valid Win32 application (the server have .net framework installed) any tips i'm missing or just isn't compatible

[formal lichen]

that seems like a pretty extreme use case and I'm assuming there's a bunch of waaaay out of date .NET stuff that possibly can't be updated even if you include newer .NET assemblies

[onyx gulch]

yep but in player settings say .net 2.0 that is even older...

[high dock]

I'm trying to use these two packages together in my Unity project:

https://github.com/oshoham/UnityGoogleStreamingSpeechToText
https://github.com/YarnSpinnerTool/YarnSpinner-Unity

Unfortunately, both have the dll file Google.Protobuf.dll, and Unity requires that there be only one of a dll file present. I've tried renaming, however, due to the different versions between the two packages of this file, they throw a weird versioning error:
The type 'ByteString' exists in both 'Google.Protobuf, Version=3.8.0.0, Culture=neutral, PublicKeyToken=a7d26565bac4d604' and 'Google.Protobuf, Version=3.15.0.0, Culture=neutral, PublicKeyToken=a7d26565bac4d604'

I've also tried overriding references AND renaming the files for both assembly definitions but to no avail.

Do you know of any way I can use these two packages?

[long ivy]

decide which one you'll use, and disable the other one in the editor (made sure all platforms unchecked)

[misty glade]

Looking for the big brains.

I have a BigDecimal class for an idle game with two members, a decimal Mantissa and int Exponent. The Mantissa must be between 1 (inclusive) and 1000 (exclusive) and the Exponent must be a non-negative multiple of 3.

I've overloaded operator* (multiply) and operator^(BigDecimal left, int right) (raise to the power).

It's not fast. I have a need to do this every frame in my client. Any obvious optimizations?

https://pastebin.com/LmspDKbj

Alternatively, any strategies for profiling this? I'm not an expert in profiling.

The code in question that's slow:

private const double ManualTapCostStartingA = 50; // Cost to upgrade level 0 to 1
private const double ManualTapCostR = 1.5;


public static BigDecimal GetManualTapUpgradeCost(int currentLevel, double reductionPercent = 1) => (((BigDecimal)ManualTapCostR) ^ currentLevel) * ManualTapCostStartingA * reductionPercent;

Hm, OK, nevermind entirely, problem is elsewhere in the code. The above still runs millions of times in a second no problem

[hushed flame]

Is there a way to standardize the size of different models to make them all the same size ?
I have the player upload various 3d models and I want to make them all the same size

[somber tendon]

you can take their bounds, and scale the model so the bounds fit into the same size...
but you need to define, what is 'the same size' first. Should a mouse have the same size as an elephant?

[turbid tinsel]

is there a way to uniformly generate random points inside a sphere in HLSL?

AKA Unity.Mathematics, due to the similarities

I can't use UnityEngine.Random

[high dock]

How can I get IAsyncEnumerable? One of my packages requires it and I was wondering if there was any way to get support for it without rewriting the package

This forum thread didn't help https://forum.unity.com/threads/wheres-iasyncenumerable-t.1246822/

[novel plinth]

that does not guarantee it would run on separate thread, if running on a thread is your intention... unless you do context switching...

if you want to await but still running on a separate thread you can do this instead

var a = await Task.Run(() => 

{
  //do your thing
});

you may need to ConfigureAwait(true) so it would switch back to the mainthread once done or else your game will freeze

if you never dealt with multi-threading, you need to learn this carefully, I agree that your use case is very suitable for that

second method without configureawait but requires custom thread dispatching

var a = await Task.Run(() => 

{
  //do your thing

   //Operation end, dispatching
   MyCustomDispatcher(()=>
    {

    });
});

due to some constraints with configureawait, it may not always work for all use cases, thus you need your own thread-dispatcher

[undone coral]

take a look at https://github.com/clemensmanert/fas

C++ has templates that accept numbers, so that's how i knew there'd be an arbitrary floating point library compatible with your choice of mantissa and exponent sizes

[undone coral]

do you mean uniform for real, or gaussian?

see https://stackoverflow.com/questions/28139344/how-do-i-do-a-simple-gaussian-distribution-algorithm-to-distribute-points-on-a-p

@turbid tinsel use voronoi in 3d and reject points greater than a certain distance away

[undone coral]

unitask already has simple things for this

[novel plinth]

just waiting for a webrequest UniTask is just too much imho...

but that's an option too, yeah

also UniTask has the same restrictions as ValueTask.. I'm not sure how would you consume the task if the request hasn't been completed yet and you or users want to cancel it as GetAwaiter().GetResult() would throw... at least it won't in net 6

[obtuse magnet]

can somebody please help me with random level generation?

[undone coral]

looks cool

[obtuse magnet]

well

its not meant to be diagnol

[undone coral]

lol

hmm

[obtuse magnet]

with spaces inbetween

and stuff

[undone coral]

well you're very close

[obtuse magnet]

i am?

id assume im quite far lol :|||

[undone coral]

i think the inside of the rooms looks nice

[obtuse magnet]

oh yeah

[undone coral]

i'm not sure why you would have this sort of off by one error

you are probably mixing up your x's and y's in a for loop

that goes through the grid of rooms

wouldn't know yet

[obtuse magnet]

i dont use a for loop :|||

[undone coral]

set your runtime to netstandard2

[obtuse magnet]

yikers

[undone coral]

well

what do you do then

[obtuse magnet]

yeah

[undone coral]

so that i can smack a "jank" emoji on it

[undone coral]

i see you have not ascended

[obtuse magnet]

oh

uh

i have spawner objects on each of the rooms

(top right bottom left.)

and i spawn a room

to make sure multiple rooms dont spawn on eachother

i have a trigger on each room

and a box collider on the spawn script (and rb2d kinematic)

and destroy and thing

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

public class RoomSpawner : MonoBehaviour
{

    public GameObject[] rooms;
    public string destroyTag =  "RoomSpawnedHere";

    private void Start() {

        Invoke("CreateRoom", 0.1f);
        
    }

    private void CreateRoom() {

        GameObject grid = FindObjectOfType<Grid>().gameObject;

        if(grid.GetComponent<RoomList>().roomList.Count >= 20)
            return;

        int rand = Random.Range(0,rooms.Length);

        Transform newRoom = Instantiate(rooms[rand], transform.position + transform.parent.position, Quaternion.identity, grid.transform).transform;

        // Transform newRoom = Instantiate(rooms[rand], grid.transform, true).transform;

        grid.GetComponent<RoomList>().roomList.Add(newRoom.gameObject);

        Destroy(gameObject);

    }

    private void OnTriggerEnter2D(Collider2D other) {
        
        if(other.gameObject.CompareTag(destroyTag)) {

            Destroy(gameObject);

        }

    }

}

but ometime i get thing like thi

[undone coral]

i think you're in a good place and you'll figure this out

the issue is in your instantiate line

[obtuse magnet]

oh yeah

i couldnt figure out how to get the pos right with the parent and spawn point pos

probably should've mentioned that...

well this is... better

but still have unreachable rooms

[high dock]

How do I do that? Can't seem to find an option in Player settings

nvm figured it out. Didn't work

[undone coral]

IAsyncEnumerable is in System.Collections.Generic

so i don't know. it's available in unity

[high dock]

This is the error I'm getting

Error: Could not load signature of Google.LongRunning.OperationsClient:ListOperationsAsync due to: Could not resolve type with token 01000037 (from typeref, class/assembly System.Collections.Generic.IAsyncEnumerable`1, Microsoft.Bcl.AsyncInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51) assembly:Microsoft.Bcl.AsyncInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 type:System.Collections.Generic.IAsyncEnumerable`1 member:(null) signature:<none>

[undone coral]

what is your app/game?

it looks like you're trying to use a google cloud api library

or is this firebase for unity?

[high dock]

This has to do with two packages in my game. They both have the same DLL file on different versions. I went into one of the packages and manually updated to be the same version as the other package, but now I get this error.

[high dock]

I'm attempting to use Google's Speech to Text API, correct

[obtuse magnet]

ive fixed the instantiate line… mostly it works now but there are a few bugs… can you help?

[undone coral]

remove all copies of Microsoft.Bcl.AsyncInterfaces.dll (or whatever it may be called)

late versions of unity use netstandard21

and do not need it

how did you get these nuget packages into your game?

don't say the nugetforunity package

[high dock]

lmao that crashed unity

[high dock]

oh hell no

i just downloaded the DLL files

from nuget

[undone coral]

you manually went through and picked out all the dependencies one by one?

[high dock]

yeah 😅

[undone coral]

it looks like you accidentally grabbed netstandard2

if you want to do this correctly you can

create a separate solution with dotnet

target netstandard21

add the package references

then dotnet publish and grab all the dlls from there

it will choose the correct ones for you

[high dock]

Yeah that's what I did

Originally I picked them out by hand

[undone coral]

hmm

i've seen this error before and i resolved it how i described

but i only remember vaguely

[high dock]

It's saying it can't load Microsoft.Bcl.AsyncInterfaces

[undone coral]

it shouldn't have a reference to it though

if it's netstandard 2.1

however, my code is netstandard 2.0... it just happens to not reference it

you can also try disabling assembly validation

i believe there is also some kind of workaround for having an assembly with that name

[obtuse magnet]

pangloss please hlep

[undone coral]

that doesn't declare any types

[undone coral]

well i've done nothing and you continue to make great progress

[high dock]

https://dontasktoask.com/

[undone coral]

all i can do is gently reassure you, like how i do with my baby or cat sometimes

[obtuse magnet]

but idk why the heck some rooms arent reachable

[undone coral]

heck indeed

[obtuse magnet]

:/

[somber tendon]

how did you spawn the rooms anyway? nvm, just need to look higher 😄

[undone coral]

no really you're doing well

like it's so close

try to not use .parent anywhere

you don't need it

it's almost always a mistake

[high dock]

let me try a thing one sec

[undone coral]

you need to deal with a "base case" the flaw is somewhere in doing the 1st room

[obtuse magnet]

alright…

but why the first room? they are all basically the same?

[undone coral]

i also sometimes reassure the chickens

[obtuse magnet]

reassuring intensifies

[undone coral]

lol

there there

[obtuse magnet]

i am happy. i am a chicken, baby, and cat all at the same time

thats a pretty darn good feat if i donsay so myself

[high dock]

How can I do this with dotnet?

only seeing these options https://b.tixte.com/snap_cd39235f.png

[obtuse magnet]

… not sure why that one didnt work

but do you know why this one still gens those annoying unreachable rooms?

[undone coral]

yeah

this is pretty painful

try editing the project file directly

and changing targetframework to netstandard2.1

[obtuse magnet]

I FIGURED IT OUT

Thank you for reassuring me lol.

[unkempt nova]

So I'm trying to encapsulate "Actions" for my autobattler, so I can Move to a position, then cast a spell or something, etc. To encapsulate them, I'm trying to use generics, and just add Actions to a list to be executed sequentially afterward. I'm having trouble adding an object to the list though. Here's the definitions:

public abstract class PawnAction<T> where T : PawnActionParameters {
    protected T _parameters;

    protected PawnAction(T parameters) { _parameters = parameters; }

    public abstract IEnumerator Execute();
}

public class PawnActionParameters { }

public class MoveAction : PawnAction<MoveActionParameters> {
    public MoveAction(MoveActionParameters parameters) : base(parameters) { }

    public override IEnumerator Execute() {
        Debug.Log($"Moving to {_parameters.Position}");
        yield return null;
    }
}

public class MoveActionParameters : PawnActionParameters {
    public Vector3 Position;
}

Usage:

private List<PawnAction<PawnActionParameters>> Actions;
...
MoveAction move = new MoveAction(new MoveActionParameters {Position = pos}); // pos is a Vector3 
Actions.Add(move); // Error

Halp?

[obtuse magnet]

im not sure how to fix your problem…

but fyi when writing code snippets

after the ‘ ‘ ‘ add cs and a line

it will syntax highlight it

[flint sage]

Visual Basic and C# have keywords that enable you to mark the generic type parameters of interfaces and delegates as covariant or contravariant.

A covariant type parameter is marked with the out keyword (Out keyword in Visual Basic). You can use a covariant type parameter as the return value of a method that belongs to an interface, or as the return type of a delegate. You cannot use a covariant type parameter as a generic type constraint for interface methods.

Note

If a method of an interface has a parameter that is a generic delegate type, a covariant type parameter of the interface type can be used to specify a contravariant type parameter of the delegate type.

A contravariant type parameter is marked with the in keyword (In keyword in Visual Basic). You can use a contravariant type parameter as the type of a parameter of a method that belongs to an interface, or as the type of a parameter of a delegate. You can use a contravariant type parameter as a generic type constraint for an interface method.

Only interface types and delegate types can have variant type parameters. An interface or delegate type can have both covariant and contravariant type parameters.

Visual Basic and C# do not allow you to violate the rules for using covariant and contravariant type parameters, or to add covariance and contravariance annotations to the type parameters of types other than interfaces and delegates.

For information and example code, see Variance in Generic Interfaces (C#) and Variance in Generic Interfaces (Visual Basic).```

[unkempt nova]

Oh, been meaning to read up on these. Thanks

[flint sage]

I think the solution is to make your PawnAction and interface and define T as out T

[unkempt nova]

Thanks, will have to read up on this

[hushed flame]

yes i want every model to fit 1m cube

is there a bound just for mesh ? i was using the collider bound but when i add a box collider, the collider doesnt fit the mesh if the mesh have alot of children

[somber tendon]

You can use mesh.bounds I guess

[foggy cobalt]

Hey Guys, does anyone have experience with an event based state machine?
I have a state machine like this:

The state machine updates the state, the state does its actions and checks for transitions. The transitions have a decision which contains logic and return a bool, if the result is true it switches to the next state.

My Problem with this is that the state controller has all sorts of references, for example I put the state machine on an enemy.
My first state is a patrol state, in that state i want the action to be "Patrolling", which basically means find a waypoint, go to that waypoint and find a new one if one is reached.

public class Patrol : Action
{
    public override void Act(StateController controller)
    {
        controller._Navigation.EnableNavigation();
        if (controller._Navigation.ReachedDestination())
            controller._Navigation.SetDestination(controller._Navigation.GetNewDestination());
    }
}

You can see here that the state controller needs a reference to a navigation system "_Navigation".
My question is how would i decouple this? If i want to remove or replace the navigation system i will get all sorts of errors, plus i maybe want to put the state controller on something else, like an NPC which doesn't have a navigation system....

I'm having a hard time wrapping my head around implementing an event based system for this and would really appreciate if someone can give me a push in the right direction.

[flint sage]

Dependency injection with interfaces the define the contract

Then if you want to change the navigation system you just create a wrapper around the new system that exposes the same contract as defined by your interface

[foggy cobalt]

So i have something like

public interface INavigationSystem
{
    void SetDestination(Vector3 pos);
    Vector3 GetNewDestination();
    bool ReachedDestination();
}
public class EnemyNavigationSystem : INavigationSystem
{
   
    public void SetDestination(Vector3 pos)
    {
     
    }

    public Vector3 GetNewDestination()
    {
       
    }

    public bool ReachedDestination()
    {
        
    }
}

and how would i inject this and where

[mighty latch]

If your Patrol state requires a type of Navigation system, it can be passed through the constructor when creating a new instance, or through a separate method that every State can inherit from I think

[foggy cobalt]

I don't see how that would decouple references. The states are ScriptableObjects, so they share all the same properties and functions and i can't pass anything through a constructor.
But even if i could. How would that look like?

public class StateController : MonoBehaviour
{
    void CreateState()
    {
        INavigationSystem navigationSystem = GetComponent<INavigationSystem>();
        State patrolState = new State(navigationSystem);
    }
}

Like this the state controller is still dependend on a navigation system...
If i would let the state care about it's dependecies like:

public class State : ScriptableObject
{
    public List<AI_Action> actions = new List<AI_Action>();
    public List<Transition> transitions = new List<Transition>();


    void GetReferences(StateController controller)
    {
        INavigationSystem navigationSystem = controller.GetComponent<INavigationSystem>();
    }
    
    public void UpdateState(StateController controller)
    {
        DoActions(controller);
        CheckTransitions(controller);
    }

    private void DoActions(StateController controller)
    {
       
    }
    private void CheckTransitions(StateController controller)
    {
       
    }
}

This will still produce errors when removed and it'll make the whole state machine way less modular.
Because now i have to either pass the navigation system to the actions and transitions or have a reference to the state on those...
Which than means I can't just simple swap actions in a state.

[nimble imp]

I'm spawning a big table of text items. This takes a long time.
Do you think the Job System would be able to speed this up?

As I understand it the Job System is not able to edit the Text.text anyways, so I would have to loop over it all again?
How would you speed up this spawning? (object pooling is slower)
Or how could I show the window first, and then start loading the list?

Also, deleting the window or moving the window around takes a long time, anyway I can speed that up?

[foggy cobalt]

Look into the new ui system, there are scroll lists which recycle items, so not every item is loaded at the same time and when you scroll the top items get placed at the bottom with the content replaced

[nimble imp]

What exactly should I search for? This sounds interesting.

[hushed flame]

if the mesh have many children meshes do i have to calculate mesh.bound for each one ?

[nimble imp]

thanks! 🙂

And for the sorting of the long list, is that achievable through the Job system? 🤔

[foggy cobalt]

sorting?

[nimble imp]

Yeah, I sort that list by Country, then City.

[foggy cobalt]

that shouldn't take very long.... how big is that list?

and how do you sort it

[nimble imp]

about 4k items

Linq

[foggy cobalt]

have you debugged just the sorting with StopWatch?

[nimble imp]

About a year ago, but I decided to postpone the perf improvements to when it made more sense to focus on that 😛

I should do it again, you think it won't affect that much?

[foggy cobalt]

i doubt it will take more than couple of ms

try it

[nimble imp]

I hope you're right 😄

Hey, Who have experience with VContainer? Can't understand how to Register factory.

[loud plume]

Anyone here good with camera manipulation and bounds of objects? My game is built for portrait devices and I have the main game camera viewport rect offset to allow for space for some UI elements. I then grab the bounds of all the renderers in the game and adjust this for the viewport rect. And zoom the camera z position to show the entire scene…

        
        foreach (Renderer render in il_renderers.OfType<MeshRenderer> ()) {
            totalBounds.Encapsulate (render.bounds);
        }

        
        if (b_resetCamera) {
            Vector3 viewPos = Camera.main.WorldToViewportPoint (totalBounds.min);
            float c_yPos = Camera.main.transform.position.z;
        
            yield return new WaitForEndOfFrame();
        
            if (viewPos.x >= 0.125f) {
                while (viewPos.x >= 0.125f) {
                    Camera.main.transform.position = new Vector3 (0.0f, 0.0f, c_yPos);
                    c_yPos += 0.5f;
                    viewPos = Camera.main.WorldToViewportPoint (totalBounds.min);
                    yield return null;    
                }
            } else {
                while (viewPos.x <= 0.125f) {
                    Camera.main.transform.position = new Vector3 (0.0f, 0.0f, c_yPos);
                    c_yPos -= 0.5f;
                    viewPos = Camera.main.WorldToViewportPoint (totalBounds.min);
                    yield return null;    
                }            
            }
        
        }```

However the arbituary 0.125f used for portrait screens isn't correct for landscape - how can I ensure that all objects fit within the camera viewport and position the camera at that point?

As you can see as the game advances the 'cropping' gets worse!

[loud plume]

Found this https://forum.unity.com/threads/fit-object-exactly-into-perspective-cameras-field-of-view-focus-the-object.496472/#post-3229700 which with a tweak or two, fixes the zooming and requires no lag for calculation!

Hey, I’m running into this issue that is preventing me from making a build of the game. since updating and trying to build I’ve been getting this popup prompting me to install unity 2019 etc, even though the unity version in the ProjectVersion.txt is up to date. Where is unity getting this idea from?

[hardy jacinth]

does a shader need something special (order or queue) to be able to read from depth texture?

[hardy jacinth]

because I want to read camera's depth for already rendered objects and terminate my raymarching at the depth

to make raymarched objects and regular geometry renderable at the same time

but SAMPLE_DEPTH_TEXTURE(_CameraDepthTexture, i.screenpos) seems to have no effect...

[undone coral]

i'm not sure why that message is so strange. are you using source control?

can you roll back before your upgrade

[terse cedar]

did someone used sqlite4unity3d for android ?

[undone coral]

you can use cinemachine to frame objects. set the target to a target group, and include all four objects in the target group

cinemachine will zoom or dolly the camera to fit all the objects

[undone coral]

there is a depth prepass in hdrp for this purpose. are you using URP?

[undone coral]

sorting a list of 4k items is going to be less than 1ms

on a typical machine

in the worst case

[undone coral]

how are you rendering the text? is this UGUI? what is writing this table

text rendering performance in UGUI is very poor

it's probalby just as bad in UITK

[nimble imp]

then what do you suggest?

[granite viper]

try an infinite scroll technique https://github.com/bugrahanakbulut/Unity-Infinite-Scroll

@nimble imp

[nimble imp]

Basically a self made ListView?

I'm considering it. I feel changing my project from GUI to the Toolkit may take some time.

[undone coral]

Which are you using? UITK or UGUI?

[nimble imp]

UGUI

[undone coral]

You can try OSA

From the App Store

But really you need to render the text in 1 pass, which is super hard

[granite viper]

can't tmp be batched?

[undone coral]

You can also put it on a different canvas

[undone coral]

It’s that the scroll view is clipped

It gets composited

[granite viper]

hm

[undone coral]

Also each row is its own thing

I don’t know UGUI and likely UITK both suck at rendering tables

Of text

[granite viper]

I see what you're saying

makes sense

[nimble imp]

Do you have a link for that OSA, can't find it on the asset store;
But that infinite scrollview makes a lot of sense to me.

[undone coral]

Optimized Scroll View is what it’s called

I’m on my phone sorry

[nimble imp]

found it 🙂

Ah, €50 is a hefty price for something that you don't know if you will have to rewrite it yourselves anyway 😛

[undone coral]

You can always ask for a refund

I try not to be too bummed about assets

[compact ingot]

I’ll tell myself that It saves you 50€+ because You then know what not to do.

[unkempt socket]

    void OnParticleCollision(GameObject other) {
        if(other.tag == "Wind") {
            Rigidbody particle = other.GetComponent<Rigidbody>();
            rb.AddForce(particle.velocity);
        }
    }

how do I access the velocity of a particle?

is it even possible?

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnParticleCollision.html

tells me there is no rigidbody attached to the particles...

[hardy jacinth]

to my knowledge - yes.

ah, no sorry

probably using built in

[turbid tinsel]

Hey, is there a way to have a fade rendermode in URP?

[compact ingot]

No individual particle collisions are tracked. You cannot get individual particle collision info afaik

[unkempt socket]

dam that sucks... Any idea for an alternative

is it possible to access the particle systems rotation from the particle?

sadly cant find any documentation on what is possible with the Gameobject of the particle

[compact ingot]

It’s best to view particles as living in their own world that only interacts with gameobjects via their transform. You can do fancy things like render particles to a utility texture and extract info from that

[unkempt socket]

hmmm

[compact ingot]

a more powerful particle api is vfx graph

[unkempt socket]

yeah im using that as well, but you can extract even less information from that

[compact ingot]

That’s kinda inherent to the way it operates

[unkempt socket]

wouldn´t it also be possible to add a rigidbody to the particle and access the velocity from that?

[compact ingot]

Maybe you should use entities

[undone coral]

what's your gameplay objective?

[compact ingot]

Most certainly not

[unkempt socket]

made that vfx wind effect and I placed a particle system inside

I want those particles to collide with the player and kick him aside

[compact ingot]

That’s a bad approach to doing that. You should just fake that pushback by a separate cpu based calculation

[unkempt socket]

never did that before, so I assume there is a better way? 😄

or you know a better way

[compact ingot]

Fake it. That’s the ‚better way‘ in all complicated sim problems in game dev

[loud plume]

Is it easy to setup via code?

[unkempt socket]

so how about i make an empty windarea which collides with the player and adds force to it each collision?

[compact ingot]

Sounds good

[unkempt socket]

even tho setting the direction of it would be annoying since the wind can have multiple directions but i guess thats fine

[loud plume]

Could you grab the direction of the wind and apply a similar force to the rigidbody during the collision detection?

[compact ingot]

Sometimes the tech needs feed back into how you design the gameplay

[undone coral]

like anything in unity, everything you can do in the inspector you can do with code

[loud plume]

Hmm, I have the solution working quite well, but will take a look at cinemachine too - thanks for the idea

[undone coral]

i was gonig to answer you there

in the future don't cross post

what if you did transform.forward = -linkedPort.transform.forward.

you have no reason to use rotations

you were overthinking this

what if you added a transform for every face

the snapping point

you sort of need a transform for each snapping point nayway

the key insight here is that you can set the transform's forward

it's not the underlying details

okay

then try what i wrote

alright i think i helped you as much as i could

the key insight here is that you can set the transform's forward

do you see why that's important @undone crow ?

i don't know why you're not trying it

you shoudl at least see what happens

it will help you put toigether a complete solution

[regal olive]

i hate to do this, but i really need help in #987007344212848710 please ❤️

[undone coral]

are you saying that you want the forward of one object's child to face the forward of another object's child?

you're trying to connect parts

and have them rotate right?

the module is always rotated the same direction
i don't know what you mean by this. clearly if you set transform.forward on something and the forwards change, it will rotate

are you trying to say you don't want the module to rotate?

there are a lot of ways to do this. you can use constraints, you can use a dummy game object, you can interpret the port's forward relative to the parent...

i mean you have to think about this

i can of course just do it for you

but you're going to do transform.forward = somewhere

because as soon as i saw you're using an angle it meant you didn't know how rotations really worked

like what if you do transform.right = ... when it's the right port? etc. etc.

you have to think a little sure

you can look up "how to turn a vector into a quaternion"

i mean there are ways to have an object "point" in a direction

that's what quaternions are for

there are lots of ways to do this

you definitely know the port's transform relative toa module

how could you not

you know which objects are ports

what do you mean relative?

alright

it's okay i think you'll figure it out

sorry i think you'll figure it out

my bad

[gray pulsar]

Personally, I think drpangloss was extremely helpful. In fact, they did the opposite of treating you like a "day 2 coder." They treated you like a competent programmer and gave you all the tools you need to solve the problem.

I'll give you a few more breadcrumbs, though.

It is trivial to construct a rotation to rotate an object such that the child's forward direction points in the direction the parent's forward direction did before rotating. Look at Quaternion.FromToRotation.

So, you need to...

1. Find the correct direction that you want child.transform.forward to be pointing
2. Set parent.transform.forward to be pointing in that direction
3. rotate parent.transform using a rotation that then aligns child.transform.forward correctly

You could also combine steps 2 and 3 into a single step pretty easily

[turbid tinsel]

is there a way to make a package dependency when exporting a unitypackage?
like, that it automatically downloads all neccessary packages
I'm trying to use package.json, but it's recognized as a text file, not as package info

[high dock]

Now I'm getting Assets/UnityGoogleStreamingSpeechToText/Runtime/StreamingRecognizer.cs(329,23): error CS1705: Assembly 'Google.Api.Gax.Grpc' with identity 'Google.Api.Gax.Grpc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=3ec5ea7f18953e47' uses 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' which has a higher version than referenced assembly 'netstandard' with identity 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

I have ``` i_numberOfObjects = i_gridX * i_gridY;

        for (int i = 0; i < i_numberOfObjects; i++) {
            float angle = i * Mathf.PI * 2 / i_numberOfObjects;
            Vector3 myPos = new Vector3 (Mathf.Cos (angle), Mathf.Sin (angle), 0.0f) * f_radius;
            Transform myCube = PoolManager.Pools ["cubes"].Spawn (t_Cube.transform);
            myCube.GetComponent<Renderer>().enabled = false;
            myCube.position = myPos;
            myCube.GetComponent<Cuboid> ().i_myCube = i_cubes;
            i_cubes += 1;
            lgo_Objects.Add (myCube.gameObject);
            
        }``` which creates a set of objects placed around a circle of `f_radius` radius - as I add more objects in i_nuberOfObjects I would like the radius to expand so that objects do not collide - does anyone have any idea how I could possibly accomplish that?

[gray pulsar]

the arc length of a segment of a circle w/ angle theta is radius * theta. If your angles are small, its a reasonable approximation to say the arc length and the chord for that same segment are equal (this is the same as saying your objects are small relative to your radius). And the chord is equal to the maximum size of the object you can fit in that given arc without overlap (this assumes 2d line segments. For objects with more depth in the direction of r this approximation might get bad).

So, the total arc length taken up by your objects is numObjects * widthPerObject, and the max arc length available at a given radius is 2Pi * radius. thus, the min radius required to fit the objects is: radius = numObjects * widthPerObject / 2Pi

Again, assumptions are the objects are small relative to the radius/arc length and depth is small relative to width. If they are placed with inner edges at the circle rather than centered on the circle the second assumption doesn't matter.

[loud plume]

😄 thats something for me to contemplate tonight - thanks @gray pulsar

[misty glade]

I have a player model, along with a state manager singleton that holds the single reference to "the player". This model can come in from the server, and I have various UI components that subscribe to an action I fire from the singleton when the model is changed (OnPlayerModelUpdated). However, this can happen several times per frame, so obviously it's not a good approach for anything UI related that's instantiating or laying out components. However, I do want these dialog boxes and whatnot to respond to player model changes. What's your approach to this?

I've thought of two so far but.. I'm not sure how I feel about either:

A: Break down each type of state update into several and emit those granular actions instead.. OnPlayerDistanceUpdated, OnPlayerCurrencyUpdated etc.. ad nauseum.

B: The UI component hashes and caches the part it cares about and rebuilds itself only if the hash value has changed. Ie..

private int _lastKnownHash;
private void OnPlayerUpdatedHandler() // perhaps this is a "crew" dialog box
{
  int thisHash = PlayerStateManager.PlayerModel.Crew.GetHashCode();
  if (thisHash == _lastKnownHash) return;
  ... otherwise do all the UI update stuff ...
}

I'm sort of thinking option B is looking good?

the problem with approach A is I'd have to write a method to compare two models - a "client" model and "server" model and sniff for differences in order to emit those actions - I don't do that now, I just send the OnPlayerModelUpdated action and let whatever UI needs to rebuild their UI based on the state

[hot dock]

Can someone please tell me how can I manually serialize an instance of a serializable class? I assume there must be an existing API for that, no?

[misty glade]

Depends on what you want to serialize it to. JSON? byte[]? XML?

[hot dock]

It is really temporary, for a "copy/paste" function

to a simple string should do it

[loud plume]

@gray pulsar only one slight issue - now its time to rotate each item to face towards the centre of the imaginary circle 😄

[hot dock]

I have been doing this so far:

But it returns me a simple string like this:
{}{}{}{}{}{}{}

unserializable classes return a {}?

Well, it cant be... which means I must be passing the wrong class... Im going to re-check

[full venture]

ok so im making a vr game but when i have my vr plugged in and i go press ctrl p it only loads in my vr not unity

[compact ingot]

All classes are serializable as empty objects. Whether their fields are serializable depends on their type and the serializer you use. JsonUtility is known for being quite limited in what it can do.

[full venture]

mb

[hot dock]

Ok, indeed. I was not passing the serializableData, but a container with the Serialized data

[undone coral]

if it uses grpc

you are going to have a very hard time at getting this to work

grpc.net doens't work in unity

period full stop

you'd have to figure out grpc core

it appears that you are on a macos device, is that right? @high dock

if it's an ARM64, you're talking to the 1 guy who's publicly documented how to get grpc.core to run on macOS

there's someone else who has littered the grpc github issues with misinformation / is deeply confused

[high dock]

I figured it all out lol. Turns out the solution was very obvious and I'm dumb. Just had to download the updated version of Google.protobuf to match my other package and then update the assembly reference overrides in my asmdef file.

I get a ton of warnings, but it works!

[undone coral]

hmm

are you on windows or mac?

i understand that it might import

but i don't know if it's going to work

probably a bit premature to say that

the protobuf assembly isn't related to those issues

don't be this guy https://github.com/grpc/grpc/issues/28974#issuecomment-1114120457

because unless you are using the grpc build for unity

it is probably not going to work

[high dock]

mac

[high dock]

I just tested and it works fine

the package i'm using has bundle files for mac

haven't tested on windows yet though

sorry, i said errors - meant warnings

the warnings are just letting me know that it couldn't find the target version (3.8) so it's using the version it does have (3.15)

[undone coral]

on an intel or ARM mac?

[undone coral]

is it a bidirectional streaming call? are you sure you tested it?

anyway good luck out there

you can disable assembly version checking in player settings

[high dock]

intel

[high dock]

Yep

[undone coral]

is it using grpc.core? then it will be intel osx standalone only

is it using grpc.net? then it won't support bidirectional streaming - i don't know if google's apis support grpcweb

[undone coral]

so it really depends what you want to support here

[high dock]

i was saying yep to the "are you sure you tested it?" bit

one of my QA people is testing on windows now

[undone coral]

grpc.core works on windows

but i don't think you have a binary for it properly

unless you use the unity grpc build

do you know if you're using grpc core or grpc net?

[high dock]

core

[undone coral]

did you grab the unity build of grpc?

you would have a folder called Runtimes

[high dock]

No, i'm using whatever is in here https://github.com/oshoham/UnityGoogleStreamingSpeechToText

see https://github.com/oshoham/UnityGoogleStreamingSpeechToText/tree/master/Plugins/Grpc.Core

it has runtimes folder so

ig?

[undone coral]

gotchyu

so yes, this will not work natively on apple silicon, if that matters to you

it will only work rosetta

[high dock]

ah

that sucks

well i mean it's not too bad

[undone coral]

there are other problems with the grpc this ships with, it's pretty old

but it won't really matter

nothing significant

i guess i should have asked you if you were using a library in the first place

i saw unitygooglestreaming... and i thought you named your own library you were authoring

[meager kite]

hi, im watching this tutorial here and i have a question

https://www.youtube.com/watch?v=Vt8aZDPzRjI

can an object have two states active at once? (eg shooting and running)

ah yeah just got to that part

so ill make a seperate state machine for weapons

[compact ingot]

you can have a hierarchical state machine where a parent state is always active while a child state is active

if you use multiple state machines in a non-hierarchical fashion you loose most of the benefits of a statemachine

[meager kite]

but if i want my shooting and movement states to be independent of one another, what should i use here?

several state machines?

that seems convoluted

[compact ingot]

if you primarily want to manage multiple active states, you would use a different model to manage your states (not an FSM)

[meager kite]

what model would you reccomend?

[compact ingot]

i dont know if there is a name for it

but you could define a set of rules for each state that need to be true for it to enable, and on each tick it would evaluate all these rules and activate the states that are valid and disable others, triggering Enter/Exit callbacks

i'd call that an AspectMachine, but thats just my name for it

you could compare it to an inference engine that solves logic questions based on facts

[meager kite]

ok ill try to find a tutorial on it

[jovial totem]

is there a way i can get a public serialized field I can drag and drop into of any monobehaviour-derived class that implements a certain interface?

[thin mesa]

pretty sure you can do that with [SerializeReference]

[humble loom]

you can, it's very limited though

you can't do it with monobehaviours for example, which to me is the ideal use case for drag and drop references by interface

[jovial totem]

that technically works but unity really doesnt like it hahah

[thin mesa]

yeah like Stropheum pointed out you can't really do it with monobehaviours which is pretty dumb. there are other restrictions and requirements, you can check them here https://docs.unity3d.com/ScriptReference/SerializeReference.html

[wooden flax]

is there a way to enable floating notification or open app info the user can do it manually because xiaomi mobile devices comes with floating notification disabled

I have a problem about deserialization, that I have no idea how to solve.

I have a list of instances of classes with a common ancestor. I would like to serialize them in a way that when they are deserialized, they can still be upcasted. How could I do that???

[frozen imp]

Since you save them as a base class, only fields it has would be saved. Objects would not have any way of knowing what it had. You can cast it later as anything, it would just not have the information

[hot dock]

Yeah, that is the issue

I have no idea how to do it

[sly grove]

Use a more powerful serialization framework than JSONUtility

Some of them can save type information alongside the data so they can be deserialized properly

[hot dock]

@sly grove I have no experience on this area. Could you please give me an example or two?

[sly grove]

Newtonsoft Json

[hot dock]

Cool, I will look into that. Thanks a lot.

[frozen imp]

You can add it by the package name in package manager. It is used internally by Unity as well. https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@2.0/manual/index.html

[hot dock]

Oh! I see

I am using it in an package i want to distribute. So I guess I will have to add it to the dependencies list

What do you mean "add it by the package name"?

I only see 3 options to add external libraries: from git url, from disk or from tarball

[frozen imp]

com.unity.nuget.newtonsoft-json

[hot dock]

mmm.... I dont have that fourth option...

at least not in 2020.3

[frozen imp]

It could be 2021+ yea

[hot dock]

So I need to copy/paste it manually? 😄

[frozen imp]

use its git repository name

[hot dock]

oh, lets see

mmm... didnt work

It worked, editing directly the Manifest.json

oh well

[frozen imp]

Glad it worked. I think it should've been just the url without the git part

[hot dock]

Well, it worked to add it

now lets see how it works serializing 😄

[fresh salmon]

To serialize and deserialize types with inheritance, you'll need to pass a TypeNameHandling value into your serializer options. See https://www.newtonsoft.com/json/help/html/SerializationSettings.htm#TypeNameHandling

[hot dock]

Thanks, ill take a look right away

[flint sage]

That looks like the wrong repository

That's the normal non unity netwonsoft afaik

[hot dock]

I am using this one, in my manifest:
"com.unity.nuget.newtonsoft-json": "2.0.2",

[fresh salmon]

Fiddle showcasing the system: https://dotnetfiddle.net/Gs1hdj

[austere jewel]

If you don't have the "add by name" option, you put the name into the git url option and it works anyway

[hot dock]

It seems to be having trouble serializing Vector3...

[austere jewel]

I would use this package too https://github.com/jilleJr/Newtonsoft.Json-for-Unity.Converters

[hot dock]

JsonSerializationException: Self referencing loop detected for property 'normalized' with type 'UnityEngine.Vector2'. Path '[0].NodeRect.position.normalized'.

[fresh salmon]

Ah yeah, the "downside" is that it serializes all public properties by default, unless you ignore them with a specific attribute. And since you don't have access to the source, you can't put the attribute.
You can however define custom type serializers that you pass to SerializeObject and DeserializeObject
https://www.newtonsoft.com/json/help/html/CustomJsonConverterGeneric.htm

[austere jewel]

The package I linked thoroughly handles all that

[fresh salmon]

Yep I just clicked on it now

[hot dock]

i will check it out...

Im still not managing to install a package using a git url... I have tried these:

• [e-mail]:jilleJr/Newtonsoft.Json-for-Unity.Converters.git
• github.com:jilleJr/Newtonsoft.Json-for-Unity.Converters.git
• https://github.com:jilleJr/Newtonsoft.Json-for-Unity.Converters.git

none of those work :/

[austere jewel]

Read the installation instructions

[hot dock]

mmm... so I have a certain DLL in my project

But if I am building a package for distribution, i have no way to guarantee that people using it will have that DLL, no?

[austere jewel]

If you mean a package like an editor extension, no, you would have to require people install it themselves or you provide it to them

[hot dock]

Ok, I cannot afford that... makes my package much harder to use... :/

I will have to find a way to do it with the normal newtonsoft package..

[austere jewel]

I'm not sure what DLL you are talking about

If you mean the .dll it mentions as a dependency, that is what the newtonsoft package as in it

[hot dock]

It says it in the instructions

[austere jewel]

Yes, and that dll is in this package

Question:

Let's say that I have a SO called Actor, and I create a couple of entries. Now, a couple of weeks later, I realized that the classname, namespace or maybe even assembly of the class is wrong. For example, I rather call it "Character".

Now, if I were to replace Actor with Character, all my existing instances would break. Is there a way to make it, so that they automatically migrate to Character?

I tried using [MovedFrom(...)], but that didnt do the trick...

[flint sage]

I'm pretty sure that you can change the name of a type as long as the GUID and content remains the same

[hot dock]

even its namespace?

[flint sage]

IIRC yes but that's a bit more iffy

If you're changing the assembly then it'll break

Keep in mind, if yuo're renaming the file you should also rename the meta file

[hot dock]

So I guess I am screwed

The problem is that I already have entries saved as "Character" and entries saved as "Actor"

so I need to change this, without breaking neither

[flint sage]

How big is your project?

[hot dock]

It is a distributed package. I am thinking about the users who have been using it.

[flint sage]

So what you can do is write an editor script that executes after the user updates (InitializeOnLoad), that finds all objects of Type Actor and rewrites the type to be Character

[hot dock]

Wont that replace the asset, messing all the references to the old ones?

[flint sage]

That is, if you create a new asset in its place instead of changing the type

[hot dock]

Im not sure how I would change the type with a script...

[flint sage]

You can either manually change the asset file to reference the GUID of the correct class or you can iirc use SerializedProperties to change the m_Script field

[hot dock]

sounds quite advanced

[flint sage]

Well yeah 😛

[hot dock]

(what a dumb decision i made...)

I guess thats the price

[fresh salmon]

Don't cross-post

The error is self-explanatory, you're using something that is obsolete

It's even telling you what to replace the obsolete code with

Hi. I'm trying to do some UIElements right now. How do I add an input event handler on this thing https://docs.unity3d.com/ScriptReference/UIElements.IntegerField.html

I want a sort of OnValueChanged event, but using the serialized property manually in the callback to that

Oh, there's a RegisterCallback

[minor mica]

Hi guys. Does any can help me with my problem? I'm unable to use the copied image from clipboard. I tried to use the old system.drawing.image and system.windows.form dlls but I think the functions from the system.drawing.image dlls only return null values. Tried to search answers from stackOverflow, found some users with similar issues but there are no solutions.

[ivory salmon]

Nope, I tried submitting a general support request via unity3d.com website but didn't get a reply. It's not a disaster - it just means I can't see any of my bug reports ever again.

[umbral trail]

you can't sign up with same email?

I can see my issue, but I can't share it

[brazen galleon]

So this might be really hard, but is there any way to change the players desktop wallpaper inside a script? kinda like that one puzzle in oneshot. Thanks

[flint sage]

You'd be writing a virus at that point

[brazen galleon]

then wallpaper engine would be a virus

[flint sage]

Not really, wallpaper engine provides a service the user wants, you're implying that you're doing something while the player is playing the game that they didn't ask for

[brazen galleon]

well this concept has been used multiple times before and no one is mad if they see a forth wall break like oneshot in the game they are playing. it doesnt classify as a virus either since it doesnt harm your computer in any way

[mint burrow]

if a game changed my wallpaper i’s be furious

[inland delta]

[pale zinc]

I'm confused; why would all your instances break?

oh woops, was scrolled up nm

[velvet cliff]

anyone good at making maps in 2d wants to help go to 2d tools pls

[pale zinc]

so you actually have 2 scripts?

[woven kettle]

Hi,

how do you guys delay update or by a float ( factor )?

I have a Raycast that makes the player fires as long as the player presses Space

Public float fireingRate;
void Update()
{
    if (Keyboard.current[Key.Space].isPressed) { Fire(); }
}

public void Fire()
{
     Debug.Log("Player is now Fireing!");
}

the current settings would make Fire() spray bullets almost like a laser!
I want to reduce the firing rate to be more believable like a regular Ak47 or MP5

[sly grove]

You would have to add some time between shots.

you cannot delay Update itself
use variables and logic to figure out in your code whether it's appropriate to fire or not fire in the current frame.

[lavish sail]

Well you can't change update's duration like that

you have to either use a timer variable or a coroutine

[sharp pine]

Coroutines!

[empty notch]

fun!

[sharp pine]

I'll give you an example:

{
     yield new WaitForSeconds(1f/FireRate);
     isAvailableToShoot = true;
}

[sly grove]

I highly recommend not using coroutines for this.

Overcomplicated and will introduce timing error

[sharp pine]

I guess you could do current frame mod something?

I've always done it with coroutines

[sly grove]

float timer = 0;
float fireRate = 25f; // shots per second;
float shotInterval => 1 / fireRate;

void Update() {
    if (Keyboard.current[Key.Space].isPressed) {
        timer += Time.deltaTime;

        if (timer >= shotInterval) {
            timer -= shotInterval;
            Shoot();
        }
    }
}```

[woven kettle]

@sly grove @lavish sail Thank you for your replies
Yes I understand that there are multiple ways of doing that, but I don't know which way would be the best for example one of my ideas, but it seems to be the best

float delay = 0;
void Update()
{

   if(Keyboard.current[Key.Space].isPressed) 
   {
    if (delay >= 5)
       {
          delay = 0; 
          Fire(); 
       }
      else 
       {
         delay = delay +1 
       }
   }

}

[sly grove]

no that's not good because you're just counting frames instead of time. Frame durations change based on the current framerate of the game

so you will shoot faster with higher framerate
Also setting delay to 0 discards the inter-frame time, leading to timing inaccuracy

[hoary pendant]

Make delay as deltaTime

[lavish sail]

Add deltatime to delay instead of 1

[woven kettle]

that seems more legit!, thank you!

[sly grove]

for the future this is also kind of a #💻┃code-beginner question

[woven kettle]

I heard from many devs who has games up on steam right now that coroutine leaves few "Junk" behind, and all of them agree to avoid using it.

[sharp pine]

Big if true. Weird.

[sly grove]

Coroutines themselves are fine - but coroutines for fast repeated timers have issues related to timer accuracy that make them not suitable. They're also just way more complicated than you need for this.

[heavy frost]

I don't know if this is the right channel to ask this in but

I've been working on this game for a while now and I want to add proper mod support where you can just drag your mod into a folder and be able to choose which mod I want to activate

How would I go with doing something like this? I'm guessing it's quite complicated since I can't find any tutorials online for unity modding

[proven phoenix]

ok this is a longshot specific question, but does anybody know how the ".SetSpeedBased()" function works in dotween

i cant get it to work

i think the problem is my tween starts already before the option is applied

[undone coral]

is there a way

to ensure there's a render thread

in batchmode

is there "windowless" as opposed to batchmode?

[hot dock]

Yeah

[sudden breach]

Hey, How would I improve my coding structure to become more advanced and efficient in unity for creating larger projects. I have been using unity for a while but after seeing after other developers I have realised their coding was more advanced and seemed like a better structure, so I'm asking how would you guys improve your structure and could you give examples, or if you know any sources about this?

[pale zinc]

Read Game Programming Patterns; it's a good primer

https://gameprogrammingpatterns.com/

[pale zinc]

That's a way too broad question and really depends on how your game works and what kind of mods you want to support.
You could check out how a game like Cities Skylines does it

[sudden breach]

Thanks

[pale zinc]

Sorry, what does that even mean?

(it sounds like nonsense to me, use coroutines if they fit the problem you're trying to solve)

[woven kettle]

Well, from what I've heard, it seems to be that coroutines creates junk temp files, and sometimes they don't clean up after itself.
But I agree with you and PraetorBlue's comment, they are not ideal for fast repeated timers

[pale zinc]

They don't create files. Things like 'yield return new WaitForSeconds()' can create a tiny bit of garbage, which that can be prevented by creating the WaitForSeconds object in Awake() and storing it in a variable

[undone coral]

if a package puts something into a Resources/ folder located in its file system, will that something be shipped into the player?

[pale zinc]

Uh, I wouldn't expect it to.. but if you can access it with Resources.Load, then yes

[high dock]

@undone coral Back again 😔. I'm getting this error when trying to build my project
Copying /Users/bremea/Desktop/Overdue/Packages/com.oshoham.unity-google-cloud-streaming-speech-to-text/Plugins/Grpc.Core/runtimes/osx/x64/grpc_csharp_ext.bundle to /Users/bremea/Desktop/OverdueBuild/MacOSBuild.app/Contents/Frameworks/MonoEmbedRuntime/osx/libgrpc_csharp_ext.bundle: No such file or directory

Why is it trying to copy from /Packages/? I have all of the assemblies in my /Assets/ folder.

[undone coral]

how did you add this package

to your unity

is there a line for it in manifest.json?

[high dock]

I downloaded the source into the assets folder. There is not.

[undone coral]

you can't copy and paste it into assets

you have to create a LocalPackages/ directory if you want to vendor in a package like that

ProjectRoot/LocalPackages/[e-mail]

[topaz scroll]

I have my states set to idle and when I debug the character is always in idle, but on start the character starts walking when i want it to be in idle animation

[undone coral]

@high dock also you will need https://github.com/grpc/grpc/issues/22485#issuecomment-933666885 if you want to build for il2cpp

on all platforms

[high dock]

Alright so I got it to build but now the game crashes as soon as I boot it. Let me try to get a crash report

https://gist.github.com/bremea/52664e10bab8673a00747a4f94b47eec

[heavy frost]

To be more precise

I'm remaking the original classic version of Baldis Basics from the ground up with much cleaner code and lots of different settings, a new engine entirely

I want to be able to support pretty much any kind of mod wether it just changes a couple sprites or changes up the entire game

[undone coral]

are you the developer of baldis basics

[heavy frost]

No

[undone coral]

or is it open source on itch?

[heavy frost]

Just a fan

[undone coral]

gotchya

what is your objective? modding?

if it's open source that's the best way to mod

asking people to PR

that's what modder swill tell you

especially the good ones

at the end of the day they just want the project source files and to PR their contributions

[undone coral]

lol

@high dock try to build for mono first

[high dock]

i'm building for mono

[undone coral]

try building devleopment mode

super hard to say what th eissue is

it could be a million things

it's probably an async error

wrong threads

[high dock]

Ah wait it's a missing script

at least i think

[heavy frost]

I want to make an entirely new engine from scratch that can run mods from a folder easily without having to redownload the entire game everytime, similar to what a lot of the fanmade FNF engines do

But its probably a lot more difficult to do in unity though

[high dock]

???

if you want to make a new engine from scratch why are you using unity

[heavy frost]

I don't mean game engine, I mean the actual game itself like

[pale zinc]

You could also look at how VR Chat does it

[heavy frost]

I'm making a custom version of the game basically

[heavy frost]

Was vr chat made in unity?

[pale zinc]

yeah, if you want to make content for VR Chat, you do so through a unitypackage

but if you don't have the rights to Baldis Basics, I can't recommend you go through with this project

[high dock]

yep it's fixed now

[heavy frost]

Baldi is free

It's 100 percent legal

And I'm pretty sure the original dev is fine with mods

[pale zinc]

It's not a mod if you're recreating it from scratch? What license is it under

[heavy frost]

Would it not technically be a fangame then?

[undone coral]

i would make it open source

the problem with unity modding is not having the source

if you give peopel the source it's easy

then they can e.g. build addressables and it just works

if they need to add code you can use Mono and load the assemblies or merge it

it's the best way

in reality nobody who authors mods

wants to deal with mods

they just want to modify the source

even if there were 1,000 mods the game would probably go from 90MB to 400MB... it won't matter

you can always auto-update

don't overthink this

[pale zinc]

I don't see anything on this being open source

Just create your own game, don't copy someone else

[undone coral]

i'm trying to say that the user @heavy frost should make his clone fangame an open source game

is there a way package authors add things to the project's link.xml

or is there another way to preserve types specified in external assemblies for il2cpp?

[undone coral]

oh my god

do they not test hdrp with medium or higher code stripping?

this is a joke

[tight cypress]

This error is popping up and I do not know how to fix it. I have been trying to fix it for the past hour. Is there any expert on C Sharp that can help me fix it

[regal olive]

im making inventory buttons and my controller's navigate only goes vertical and horizontal, but i need it to go diagonal

[shadow seal]

You likely have two classes with the same name, not an advanced issue

[humble leaf]

(They left)

[humble loom]

you don't need an expert in c#. you have two Update methods

or two scripts called PlayerAttack

oy

[regal olive]

I have an extremely specific need (want really). I want to run Unity headless. The same way you can create dotnet console projects using the cli, I want to create a Unity project and build it for Android, all from an Android device. I should be able to instantiate everything I need from scripts without the need for an editor, I just need a way to create and build a project.

Any resources to get started at least?

Thank you.

[flint geyser]

How do I create such a mini-camera view in the right bottom corner of scene view through scripting?

I do not need some custom inspector guide regarding it, only the action of creating the mini window with camera

That invoke in update with 2s delay has no sense. It is, every frame schedule invoke function with delay. Why don't you just call it normally\

hi guys i want to try calling a method in unity from python using this package https://docs.unity3d.com/Packages/com.unity.scripting.python@5.0/manual/inProcessAPI.html but the example only shows calling debug.log() from python. Im wondering is it possible to call a method in Unity from python using that package?

[untold moth]

Sure. Should be possible.

[minor shadow]

aight gonna try

[undone coral]

what's your objective?

the python scripting package does not work in standalone players

[undone coral]

what is your objective?

[minor shadow]

i want to use the tiktok live package in python to make a tiktok live game that responds to likes, shares, gifts etc

found this error when installing the package

[minor shadow]

wait so what should i do here

use webGL perhaps?

man this package is so confusing, anybody here know a better way for a python script to communicate with Unity? im talking about passing data here not just keyboard input stuff

[untold moth]

I don't think that you can interact with the game app from outside regardless of whether it's C# or python. The best you can do is something like http requests, or hook to some outside api from inside unity.

[minor shadow]

oof this is what i thought initially, okay thanks for the info man

[undone coral]

you're at the start of a very long journey

[minor shadow]

i think not that long bcs i found this awesome library https://github.com/Siliconifier/Python-Unity-Socket-Communication/tree/v1.0.1 😄 just tested and works like a charm

[compact ingot]

journey just became longer 😉

[humble loom]

i'm curious, has anyone done an implementation of using "intelligent" yielding in a coroutine for like building caches and things like that? something like: https://paste.myst.rs/yywcj9np

an example as simple as this i would probably just use async but i'm referring more to the principle than this specific implementation

say it was like a batch spawning system

something that has to happen on the main thread

[sly grove]

I think it'd be better to use system time which you can measure within a frame

Basically you could do something like have a budget of N milliseconds after which you'd yield

[humble loom]

Oh true

[humble loom]

Does deltatime not change within update?

Oh I get what you're saying. Like it'll increment but it'll start as time.time - time at last frame. So it wouldn't be counting the number of milliseconds ON this frame

[gray pulsar]

I don't think it does increment. I haven't specifically tested, but my understanding is that Time.deltaTime has a constant value through the whole frame. That's what the documentation implies:

The interval in seconds from the last frame to the current one (Read Only).

[humble loom]

Makes sense. Yeah I'd either have to use system time or cache time.time. though I thi k the latter is less precise

[wooden flax]

hi devs, as you all know that icons appear grey in android notifications, is there any way to make them colorful or make them appear the actual image

[sly grove]

Nope it's the same throughout the entire frame

It wouldn't really work if it wasn't

[humble loom]

yeah made sense immediately after i asked. guess i never really thought about it though but yeah

https://paste.myst.rs/6e794b5w

this seems like it should work

stopwatch starts at the beginning of each frame, if it runs for more than half a frame, it yields and resets

[humble loom]

oh crap it's hanging. i think i have to use milis

[humble loom]

cool that's working perfectly

[real kiln]

I cant assign a function in my code to an event in animations

[humble loom]

how did you set up the animation event?

you should be able to drag a gameobject as a reference and you'll be able to choose any of its PUBLIC methods

[real kiln]

right but thats a private method

should I change it to public?

[humble loom]

if you want it to be triggered by an animation event that is required

[real kiln]

I was following a tutorial and the guy used the same code but his worked

[humble loom]

animation events are most likely classes under the hood, so they'd function like any other class that takes your script as a reference

[real kiln]

hmm i dont think i understand

[humble loom]

again i asked you how you set up the animation event

i have yet to see that

[real kiln]

I am trying to set an event at 25

and then assign the function deactivate

but it does not showup

[humble loom]

you need to add an event

[real kiln]

i did

[real kiln]

but i cannot assign deactivate which is the one i need

[untold moth]

Make it public

[real kiln]

i tried but unity crashed

[untold moth]

Don't think that related...

[real kiln]

hmm

ok

[humble loom]

you should have an object reference though. that's weird

[real kiln]

yah i find it strange

[humble loom]

should look like this when you double click the event you created

[real kiln]

i cant double click

[humble loom]

do you have your object selected? the one you're configuring the animation for

[real kiln]

also i did try setting it public didnt work

[real kiln]

yessir

actually

when i click 25 to set event it clicks off from the object to sample scene

is this normal?

[humble loom]

off the object or off the animation event

[real kiln]

off the object

friends used same code as mine their's work so i dont think the issue is with my code

[humble loom]

can you record a video of yourself doing this step by step
moving the play head to a location
selecting the add event button
navigating to the inspector window

i can get there literally no problem

made a new animation, moved the play head, pressed the button

[real kiln]

can we join a call?

[humble loom]

sure. it's late though so i can't go on mic

actually nvm i can

[real kiln]

ok

[humble loom]

are there no vc's in this discord

well that was an easy fix ^_^

[untold moth]

What was the issue?

[real kiln]

assigned the wrong script to the object lol

[jovial totem]

What on earth do these errors mean.

Does it have to do with gizmos

does it say what script it's occurring on

Then do it?

well obviously before where the error happens

so before line 48

right

Thx

[unkempt socket]

any idea, why this doesnt work? You can barely see the fade in/out animation

its like 1000th of a second

[hollow garden]

you are not using a coroutine to break it up into frames

so it happens in a single frame

[unkempt socket]

so id do it like that?

sry i didnt quiet understand them yet ´:D

[silent fox]

hey i am going to ask here because in the other i was in said it was really hard but i am not sure if it is not pls warn me

can i ask?

[unkempt socket]

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

you mean this ine right

[silent fox]

😅 i am making a first person controller using CharacterController and i repeat NOT RIGIDBODY. so i don't want my player to sprint mid jump or stop sprinting mid jump and all that. basically i want to make that if you have momentum and you are sprinting and jump you cannot stop sprinting but if you are not sprinting you cannot sprint during your jump. How can i make this?

[unkempt socket]

brooo, not trying to be mean right now... It´s not as if I´m not doing my own research.. whatever Ill do it myself

if you dont want to answer, than just dont type like cmon...

[worldly rose]

you should do your own research

that's how you get better

[unkempt socket]

thanks anywaysim coding since 6 years and am a webdev and have to do this for university 😄 I know how I learn to code^^

[silent fox]

no uhh so for ex: you can sprint mid jump or you can stop sprinting mid jump i don't want that i want to be at the sprint speed if we are already sprinting and we cannot stop it. if we are not and just jump we shouldn't sprint and we should jump at the default speed.

[unkempt socket]

after this project ill never touch unity again and I asked politely for an answer. People who feel like answering can do so, people who feel like "I´m too good for this, this is beginenr stuff" can just sit back and chill

you did, but you couldve just leave it at that

[silent fox]

sorry to bother or anything or i am not trying to be mean but did anybody understand this pls help me?

[buoyant vine]

unnecessary unfriendly.. and i say that lol

[buoyant vine]

well its basically you make a state machine with swapping objects

interface Move{ Move Move();} lets say you got that

then in your character

[silent fox]

yeah

[buoyant vine]

void Update(){ if( Move() != null) currentMove = ...) }

[fresh salmon]

Don't bother, they've cross-posted in #archived-code-general

[silent fox]

no i am gonna try both

if one doesn't work try the other one

[buoyant vine]

in your jump you just dont react to input which you would react to move

just statemachine

both will work

without knowing what the other is

[fresh salmon]

Cross-posting is against the rules, for your information

[buoyant vine]

and cross posting is shit

oh really ****

sorry i actually didn't know

i kinda didn't understand can u expand a little?

[jovial totem]

Yeah, but how

[fresh salmon]

Looking back at the stack trace, this is an internal Unity error (line numbers are all at 0). You can safely ignore that.

[jovial totem]

I’d love to but it halts my game

[fresh salmon]

Restart the Editor, if that doesn't fix it report a bug and attach the Editor logs.

[buoyant vine]

https://pastebin.com/xbwmaFfH

in your character controller you just swap states if the return is not null

null == stay in same state

[silent fox]

hmm

thanks for helping out

you can trigger internal errors like this with unconventional code - the error suggests you're using a constructor in a UnityEngine object, so you'll need to look at your code and see if you're doing that

[buoyant vine]

if the object is in state jump the key input shift has no meaning

[undone coral]

if you want to animate / tween things, use DOTween. DOFade achieves this. you should use a canvas group

[undone coral]

don't overthink this. create 4 rectangles that block raycasts to "cut out" the area you want to make interactable.

Hey,

I'm using ParentConstraint on all children objects to assign a parent for them
but when I want to delete the parent, I also want to delete all it's children.
Is there is anyway to find which gameobject has a certain Item as a ParentConstraint.source ?

[undone coral]

no. you would have to store it yourself

[dark cypress]

Hi, is there a package I should read up on if I want to spin up Unity in a remote VM, send it some C# code, and see if it compiles? Then run unit tests and retrieve its XML document of results?

I think compilation errors are outside the purview of the Tests suite, right?

I have a "Runtime C#" asset but that seems maybe overkill, to have Unity in Play mode to test compilation

[woven kettle]

hi, thanks for the reply but what if I used the other one instead childConstraint ?

can I add the childConstraint on the parent and keep track of all the children under ChildConstraint.source ?

[undone coral]

what isy our objective?

you just make a field

don't overthink this

[SerializeField] private ParentConstraint[] parentConstraints;
void OnDestroy() {
 foreach (var child in parentConstraints.Select(c => c.gameObject)) {
  // you should probably assert that the parent constraint
  // specifies this object's transform as its only source
  Destroy(child);
 }
}

@woven kettle

there's no way to do this automatically

ChildConstraint doesn't exist

[woven kettle]

I need the parent to somehow know all it's children Percisily , Imagine if I deleted a gun with attachements ( children ) and a mag ( child also ) ..., the gun would disappear but everything else would just hang in the air and console would have an over float of errors.

[undone coral]

well

you make a field

see my example

don't overthink this

[undone coral]

this is a very long journey

what do you mean send some c# code? what's your objective?

[woven kettle]

it's not that simple, its a multiplayer game and that ParentConstraint would be on the attachements and mags not on the weapon ( the source in this case would be the weapon )

where could I just make a filed that is aware of all the parentconstraints and whne the object gets destroyed, im supposed to loop through that and compare the source of each to see if it matches the ones that has been destroyed ?? ... I dont think that is the best idea

[undone coral]

you can make the field on a new script

i think maybe you should ask #💻┃code-beginner @woven kettle because you're getting stuck on something

[woven kettle]

I'm not stuck , but I dont think you get it yet, but thanks for your help , appreciate it

[undone coral]

you're trying to destroy some objects right?

why in the world wouldn't you know what those objects are

surely you have them in your scene or you Instantiate them somewhere

var attachment = Instantiate(someAttachmentPrefab);
attachment.parentConstraint.sources[0] = someWeapon;
someWeapon.implicitChildren.Add(attachment);

it seems so straightforward that yes maybe i do misunderstand

but you're also talking about something that makes no sense

i didn't show any comparisons or any loops

and besides, even if you have 10,000 attachments, so what... computers loop all the time, it won't register in the profiler

so you sound stuck

are you working with PUN? @woven kettle

anyway @woven kettle the answer is no. there's no pre-existing unity api for finding all the objects that use a specific object as a source in a parent constraint component

that's in the docs

so i guess you'll have to make a list and keep track of it in a place you deem appropriate

or just parent the objects

[woven kettle]

I'm destroying a Gun >>> the Gun has no idea if there is an item (like: attachement or magazine ) with a parentconstraint script attached to it and has Gun as the source.

if runGetComponentsInChildren it would only get the children in the hierarchy.. ( the attachments and the mag wont show up )

so to make a script/field on the Gun itself to keep track of those, is one possible answer (YES!)
but I was thinking, what if I used ChildConstraint instead ? , if I'm not wrong, to use ChildConstraint i need to add it to the Gun instead to the attachements, where I can use get component on the Gun and look for each source on the list

[undone coral]

there is no childconstraint component

i think you should go to #💻┃code-beginner

so to make a script/field on the Gun itself to keep track of those, is one possible answer (YES!)
this is the answer... go code! by now you would have finished

[woven kettle]

wow, i used to see it in unity2019, but its no longer there in 2021

[woven kettle]

yes, i think i know why we both were confused, thanks ^^

[undone coral]

it was the second time i wrote that line

you can go to #💻┃code-beginner and ask questions like this

i don't think i was ever confused

[regal olive]

So I have this line renderer I was wondering how I would set the end of the line to follow a specific point like a mouse. And I want the rest of the line to bend

[icy aspen]

Hello everyone I have a question

Is it possible to make a public function which you can input in the script properties

So there would be a function that you can input there

[regal olive]

Use a trail renderer

That doesn't really help 😅

[undone coral]

create a 3d object or a plane that helps you map the 2d mouse positions to a 3d position using raycasts / the pointer event data. then set the line renderer's positions to be attached to that point. if your intended effect is to make a 3d rope... use a rope package, and use a joint to connect the rigidbody end of the rope to the 3d position you determined

don't

say

that doesn't help

say what your objective is

[regal olive]

-_-

Ok well I was about to go more indepth until you said that

Ill get help from somewhere else

You can see when people are typing I thought you'd figure that

[undone coral]

#💻┃code-beginner use a UnityEvent

[regal olive]

@undone coral
You don’t need to be so passive aggressive to everyone

[fresh salmon]

Oh don't worry it's a frequent thing to see from them

[icy aspen]

thanks

Receive C# from an AI service, drop it in a file for the Unity Editor to compile and ensure it compiles in the current context (eg. no Editor namespace references, no inappropriate types like int32), then run unit tests. What I'm stumbling with is how to get a notification if won't compile. Like, I know [AssemblyRefresh] or whatever the hook is, but if it doesn't compile, how do I get callback?

[undone coral]

what is the big picture app or game here

are you trying to filter out code that doesn't compile, or is the expectation that a typical code snippet generated this way will compile?

[dark cypress]

I guess filter out code that doesn't compile

[undone coral]

999/1,000 to 9,999/10,000 code snippets will not compile

that aren't the absolute minimum basic complexity

is that okay?

why does it have to be in the unity context?

[dark cypress]

Yeah I'm not worried about efficiency yet

[undone coral]

it's very unlikely such a generator will be aware of the unity api, there isn't enough open source unity code for it to work for that

have you gotten something that works with an ordinary command line c# compiler?

you can use stub versions of unityeditor and unityengine apis, they are available on github

[dark cypress]

Stub version, like... headless, call on command line?

[undone coral]

no

stub version meaning code stubs

[dark cypress]

Like, the things that get expanded in a C# code snippet? Templates, sort of?

or an API you implement

[undone coral]

hmm

i'm saying you can use a mocking library to mock the unityengine and unityplayer assemblies

you don't need the unity editor to see if something compiles

you don't need the implementations of the functions

you only need type signatures (types and function signatures)

[dark cypress]

I'll check it out, thanks

[undone coral]

does that make sense?

do you see why you don't need the editor

let's say you just had

[dark cypress]

It does, but I'm probably going to stick with an editor solution since I'll be running unit tests using it afterwards anyway

[undone coral]

well then i suppose you can copy and paste a C# class into a project

then try to build and run the tests from the command line

i don't know at what level you want or need to automate this

what's the bigger picture app / game?
