[rustic rain]

then should work as intended

index in inmanaged component should be valid

because internally they are used to render your mesh/material pair

[devout prairie]

exactly

not sure why i'm getting this

[rustic rain]

can you make a screenshot

of what component you even use

[devout prairie]

so when i run this code on for example my terrain object, which is baked inside the subscene, it returns the mesh

whereas these objects are baked to prefabs inside a baker, pulled from a scriptable

ie they don't 'exist' in the runtime until i explicitly spawn the prefabs

[rustic rain]

but they should be converted

and registered properly

because they will exist as entity prefabs

I need screenshot

of what you use

to tell you exactly

whether it's correct one

because it was really missleading when I first encountered this

[devout prairie]

this is one of the entities after spawn, at runtime

so the mesh index of 311 looks ok

[rustic rain]

yeah, this should be right one

how do you get try to get mesh

again?

[devout prairie]

and this is the target mesh in the shared managed component

[rustic rain]

no no no

you don't obtain it from this array component

it's wrong one

it doesn't match runtime indices

it's for import only

and export

[devout prairie]

yeah i'm not, i'm just showing that it does match up with that list

this is how, same as we discussed, with reflection:

[rustic rain]

irrelevant, whatever indices it has, are not meant to match MMI component

[rustic rain]

well

it's unclear

what MethodInfo is that

what is HybridRenderer

and etc

besides

you don't need reflection in runtime

just use reflection to get BRG reference

and that's all

[devout prairie]

look at the commented line

as explained, i've tested this with both methods

[rustic rain]

just use brg one

it works and it's faster

and show what error does it even give you

[devout prairie]

yeah the brg is faster, but i tested with both, and both throw this error

[rustic rain]

🤔

try to debug and inspect BRG

maybe that will give some insight

[devout prairie]

and as mentioned, both work fine for objects that are already 'spawned' ie active within the baked subscene

[rustic rain]

hopefully it shows all registered assets

[devout prairie]

yeahhhhhhhhhhhhh figured i'd ask if you'd had this

have you tried brg.GetRegisteredMesh on a runtime spawned entity?

[rustic rain]

yeah

besides

runtime spawned entity

is no different than non-runtime

they use same index

and in my case

I stored prefabs

and they worked fine

[devout prairie]

that's exactly what i'm doing

[rustic rain]

just debug it and see what's going on exactly

your error mentions

some out of bounds error

[devout prairie]

i think possibly i might be hitting GetRegisteredMesh too soon after spawn or something

[rustic rain]

with very huge number

[devout prairie]

or maybe need an updated reflection reference to the brg or something

[rustic rain]

potentially there is smth else behind this error 😅

[rustic rain]

I use [CreateAfter]

because from what I remember, BRG is created in OnCreate

actually

let me lookup that code

[devout prairie]

it could actually be where my system is positioned in relation to init or presentation

[rustic rain]

[CreateAfter(typeof(EntitiesGraphicsSystem))]

    [UpdateInGroup(typeof(EarlySimulationSystemGroup), OrderFirst = true)]
    [CreateAfter(typeof(EntitiesGraphicsSystem))]
    public partial class EntitySelectionTool : SystemBase

EarlySimulationGroup is Simulation

            // Obtain BRG from graphics system to get Meshes through ID
            var sys = World.GetExistingSystemManaged<EntitiesGraphicsSystem>();
            var fieldInfo = typeof(EntitiesGraphicsSystem)
                .GetFields(BindingFlags.Instance | BindingFlags.NonPublic)
                .First(x => x.FieldType == typeof(BatchRendererGroup));
            _brg = (BatchRendererGroup)fieldInfo.GetValue(sys);

[devout prairie]

yeah i'll try reposition where the system actually runs

CreateAfter could be useful though thanks, i actually had to delay my system and create the reference in OnStartRunning

This is me trying both methods:

[rustic rain]

var meshInd = aspect.mmi.ValueRO.MeshID;

this is how I obtain meshID

MaterialMeshInfo.MeshID

[devout prairie]

practically the same

[rustic rain]

BatchMeshID
I store it as this type though

and then like this var mesh = _brg.GetRegisteredMesh(pair.Key);

[devout prairie]

k going to grab some food and then try out repositioning my system, it might be that i'm trying to get the mesh id before it has been fully initialized by the graphics system, or something along those lines

[rustic rain]

you can ensure your system runs after all subscenes are loaded

allthough nvm

seems like your case is different from mine

[devout prairie]

yeah it's not that

yep, it's more i think trying to get the mesh id too soon after spawning, ie same frame but before graphics initialization of the entity, or something

for example its as if - i spawn the entity, my system reads the mmi which has been added but not yet initialized somehow

[rustic rain]

doubt that's the case

but you can see

by trying to create your system on demand

on click of some button for example

after you know for sure everything is loaded and runed at least once

[misty wedge]

Anyone know what this Unknown block of memory is for?

[devout prairie]

Couldn't resist trying, so i moved my system to ensure it runs after this system:

And it works.. So i was obviously able to read the MMI component from the newly spawned entity, before it had actually been initialized by the graphics system

[devout prairie]

i think this is DOTS' secret pr0n stash..

where it keeps all it's dodgy mp4's

[proud jackal]

😉

[rotund token]

Could you just get all scenes and exclude any in build scene list

[coarse turtle]

yea i was thinking about that since the scene list won't include those subscenes

and I can ignore certain directories for prototyping scenes too

[misty wedge]

How can I force the inspector select a specific entity? Create an EntitySelectionProxy and set Selection.activeObject to it?

[rotund token]

You don't need to create it yourself

But hmm, probably easiest way

[misty wedge]

I guess the only downside is that the objects are only cleaned on Resources.UnloadUnusedAssets iirc

unless you manually destroy it on unselection

[rotund token]

You can just create 1 copy in your tool

Don't need to create it new every time

[misty wedge]

It's all static, I guess I'll just store a static instance

How does unity do it? Do they have a static instance too? Since then I could just use that

[rotund token]

I'm still not sure why this was all made internal, it's like they don't want us writing custom tooling

Entity selection proxy, property inspector etc

[misty wedge]

There's actually a EntitySelectionProxy.Select(World, Entity) method that I missed

[rotund token]

Yeah I was going to suggest that

I just didn't recall what it did

Does it actually set it to selection?

(not at pc)

[misty wedge]

Yes

EntitySelectionProxy has a Select instance method that just sets the active selection to the object if it isn't already that

(Which the static method calls after creating the scriptable object)

public void Select()
{
    // Don't reselect yourself
    if (Selection.activeObject == this)
        return;

    // Don't reselect the same entity
    if (Selection.activeObject is EntitySelectionProxy selectionProxy && selectionProxy.World == World && selectionProxy.Entity == Entity)
        return;

    // Can only be Runtime if directly selected
    SelectionBridge.SetSelection(this, null, DataMode.Runtime);
}

[rotund token]

👍

There you go then

I know I had used this method in the past exposed but I know my current wrapper doesn't expose it for some reason

But I think that's just because I haven't needed to select something in a while, just get current selection

[misty wedge]

Yeah I wanted to be able to select the entity for a hybrid entity when selecting it in the scene

Since it's so annoying to always have to search for it

Seems you need to delay the selection by a frame though

[hybrid jay]

Am i right in thinking that in an ISystem you can't access any of the managed command buffer systems?

when burst compiled

var ecb = state.World.GetExistingSystemManaged<EndInitializationEntityCommandBufferSystem>().CreateCommandBuffer();

(0,0): Burst error BC1016: The managed function Unity.Entities.SystemState.get_World(Unity.Entities.SystemState* this) is not supported

I wanted to avoid the sync point in using a command buffer manually but if thats the only option then it'll do

[rotund token]

You can you're accessing them the legacy way

You should access command buffer systems via singletons in 1.0

[hybrid jay]

ahh, got an example anywhere?

https://docs.unity3d.com/Packages/com.unity.entities@1.0/manual/systems-entity-command-buffers.html

the docs only use the old way

[rotund token]

var system = SystemAPI.GetSingleton<EndInitializationEntityCommandBufferSystem.Singleton>();
var ecb = system.CreateCommandBuffer();

you don't need AddHandleForProducer when doing it this way

[hybrid jay]

cool thx

[covert lagoon]

I can't have a MonoBehaviour inside a namespace anymore?

[rotund token]

sure you can

my ide is setup to not even allow something to exist outside a namespace will just auto add it

so i'd definitely run into issues if this changed

[covert lagoon]

What the fuck.

Is this random?

I make an authoring MonoBehaviour in a namespace, Unity recompiled, did something domain something blablabla, I tried to add it to a GameObject in a subscene, couldn't find it in the "Add Component" menu, tried to add it to a GameObject outside the subscene, couldn't find it in the "Add Component" menu either.

[rotund token]

is the Filename exactly the same as the MonoBehaviour name?

[covert lagoon]

Removed the namespace block around the MonoBehaviour, Unity recompiled, etc, and this time I could find it in the menu.

Well, I commented the namespace block out.

Then I un-commented it, and again I couldn't find it anymore.

[rotund token]

What's your namespace

[covert lagoon]

Then I removed it entirely, could find it again.

[delicate swan]

All of my author monobehaviors are in nested namespaces, but there is an issue on whatever build I've been on that occationally it like, 'misses' monobehaviors during a recomple

[covert lagoon]

Then I added it back, and now I can still find it.

[covert lagoon]

EcsTutorial.Authoring.

[covert lagoon]

Yes.

[delicate swan]

Try looking at the script in the inspector, if it says something like 'can't find behavior', try reimporting the script by right-clicking it

That usually fixes it for me

[covert lagoon]

It didn't appear here the first time Unity recompiled after I created the script, I tried to refresh and nothing happened.

Then when I commented out the namespace block for the first time, it appeared.

When I un-commented it, it was still there but I couldn't find it in the "Add Component" menu anymore.

I don't have [DisallowMultipleComponent] or whatever on it, and I tried to add it on GameObjects that didn't have it anyway.

[devout prairie]

I've had similar a few times, in fact a couple of days ago.. basically just have to mess around with it to trick it into recognizing and showing up in the editor again

I think normally i'd just create a new script with slightly different name and copy the contents over, ensuring i update the class name to match

[misty wedge]

Weird, I don't think I've ever had this issue

All of my scripts are in namespaces as well

[devout prairie]

I've always had a sneaking suspicion it's VisualStudio related tbh

[hushed lichen]

Rider from JetBrains is very enjoyable to work in with Unity. Just a random recommendation 😛

[rotund token]

A lot of users here use rider, but it is a little rough if you are not a student or don't have an employee to pay for a license

[hushed lichen]

Not wrong.

[rotund token]

sigh Unity.Logging why do you not respect my authority

[rustic rain]

🥲 20 mins

[rotund token]

                .SyncMode.FatalIsSync()
                .MinimumLevel.Set(MinLogLevel)
                .CaptureStacktrace()
                .WriteTo.JsonFile(
                    absFileName: Path.Combine(logDir, "Output.log.json"),
                    outputTemplate: $"[{{Timestamp}}] {{Level}} | {world} | {{Message}}")
                .WriteTo.UnityDebugLog(
                    minLevel: this.currentLogLevel,
                    outputTemplate: $"{world} | {{Message}}{{NewLine}}{{Stacktrace}}")
                .CreateLogger(LogMemoryManagerParameters.Default);```
It writes the UnityDebugLog output template to the json file for some reason

[rotund token]

i've been seeing unity api services fall over a lot recently

on forums, logging in via hub

[rustic rain]

yeah

[rotund token]

it's not good

[rustic rain]

but failing build because of it?

jeez

[rotund token]

i'm quite tempted to install a second pirated copy of unity editor just to avoid this shit... (i have 2 licenses so i feel no guilt)

[rustic rain]

I am lucky it built after that fast

[rotund token]

yeah thankfully incremental will rebuild fast

[devout prairie]

i came to a similar conclusion with adobe software

[rotund token]

if someone can offer me a better service, I am going to be tempted to take it

[devout prairie]

got so tired of media encoder / ae / etc breaking when i needed it to work

🏴‍☠️ 🦜

arrrrr

with adobe, you basically threaten to end your subscription every 18 months or so and they drop the monthly price to keep you in the loop

[misty wedge]

oof 20 minutes for a build

[devout prairie]

the loop being, of course, a perpetual loop of utterly needless updates that achieve nothing and give you nothing

[hybrid jay]

Whats the best way to generate a seed for a random inside an ISystem?

[rotund token]

hmm good question

[hybrid jay]

actually nvm, can just not burst the OnCreate and use DateTime?

[rotund token]

maybe just generate a seed in OnCreate and increment it each frame (or power prime or something) [what you said]

[covert lagoon]

Why does TransformAspect.LocalPosition appear as readonly in the docs? https://docs.unity3d.com/Packages/com.unity.entities@1.0/api/Unity.Transforms.TransformAspect.LocalPosition.html#Unity_Transforms_TransformAspect_LocalPosition

It's not readonly in the real source code:

[CreateProperty]
public float3 LocalPosition

And I can reassign it just fine.

Is it a DocFX bug?

[late mural]

is there anyway to get read write access to a singleton component in a monobehaviour?

[late mural]

wait a second, does the SystemAPI work in monobehaviours?

[late mural]

no, sadly they do not

[rotund token]

no as you discovered it's 'System' API

[late mural]

i was hopeful atleast...

trying to find a good way of doing ui, everything seems to be a pain though, using a system for the ui makes getting the ui gameobjects really challenging, but if i use a monobehaviour for the ui then i have the nightmare of trying to get access to components in a monobehaviour, which is not fun, ughh

[rotund token]

i use a system but i use UI toolkit instead of ugui

i think it works much nicer with entities

[late mural]

haven't heard of either of them, so ill look into them, thanks

[viral sonnet]

i had high hopes that the new unity.physics wouldn't have this quirk that sphere casts have hits on the edge but it's pretty much the same. oh well, on to sorting out best hits ^^

[coarse turtle]

https://assetstore.unity.com/packages/tools/gui/nimgui-a-1-draw-call-ui-209126 (sorry my shameless plug - can remove if unnecessary) - I was using my own thing although more more for debugging directly in systems using OnUpdate because I figured an immediate mode gui works decently w/ data oriented design. Still using it and working on it to get the static API burst friendly and working decently with ISystem structs + have a few more widgets ironed out

[tribal pollen]

I fixed all the errors with upgrading to entities pre15 now, but most of my entities aren't visible in the game screen anymore, even though they've been intantiated from a prefab. was there some change regarding this?

all the entities exist still, and my game is playing out, Just my once-visible versions of them aren't visible anymore.

[rotund token]

you updated from 1.0 exp to pre right?

hmm not sure

i didn't think much changed here graphic wise

[tribal pollen]

yeah.

[viral sonnet]

huh, unity physics treats a plane as double sided. meaning, it gets the same raycast hits from front and back. that is very different to legacy physics where a back raycast doesn't have any hits. that's really annoying to deal with

[rotund token]

interesting

did not know old physics didnt do this

(or that unity physics did)

[viral sonnet]

yeah pretty odd tbh. i mean it likely will stay that way and i just to rewrite my algorithm to deal with it (calculating thickness of objects that obscure the view to the player)

makes it pretty complicated though tbh. look at this mess to evaluate the thickness of the edge. those rays are point+normal. red is from target -> camera position green is camera pos -> target. i guess i have to evaluate against the real surface normal or smth to figure out if i'm inside

my old method was just raycasts but that was pretty unstable in any game environment

does anyone know how i'd get the real colliding triangle? i'd guess with ColliderKey but i have no idea how to use that

hm, when i rethink this and apply some basic trigonometry i can get away with just one raycast. fingers crossed this will hold up in more complex situations 😄

[viral sonnet]

i don't feel useless yet for high level programming, architecture and optimization but for basic math problem chatGPT can replace my brain haha

wanted to find the intersection point of a direction vector through a plane and chatGPT just staight up told me the math. i mean, it's nothing new but googling wasn't helping much

(might have to do with the horrible SEO on math sites)

[rustic rain]

let's pray they don't remove this chat from public

[rotund token]

i should probably have a look at this at some point

[rustic rain]

just do

you can login with google account

his knowledge is limited up to 2021 though

which is obvious dealbreaker for dots

[rotund token]

more like effort and lack of need atm

[rustic rain]

nah, just a little bit of fun

ask him about modding some kind of old game you like

kek

Sadly, he doesn't know about new version in rimworld, but he answered old one correctly

[rustic rain]

@rotund token btw sir, have you tried to tie New Input System with UI toolkit?

keybinds for UI and etc?

[rotund token]

yes i only use inputsystem/uitoolkit

[rustic rain]

mind explaining how you tied them?

[rotund token]

it has built in support

[rustic rain]

wait what?

[rotund token]

don't really need to do anything

[rustic rain]

how?

[rustic rain]

I want basic Cancel event registration

[rotund token]

just add a input system ui input module

to your ui document

[rustic rain]

and then?

[rotund token]

it just works

those are input system bindings

in the drop downs

[rustic rain]

I know

but I mean

I want my window to close on Cancel event

as one of examples

have you done similiar stuff?

[rotund token]

yeah actually

i wrote a stack history system into my state like 2 weeks ago

[rustic rain]

yeah, I remember

damn

[rotund token]

i just call
ClientState.UICloseAllPopupsOrPop(ref systemState)

[rustic rain]

I used to do it with stack as well, but I didn't like the approach

[rotund token]

names a bit of a mess atm

but it will close all popups OR close a window to the previous

alternatively just ClientState.UIPop(ref systemState)

to pop back just 1 window

[rustic rain]

but I guess if you did it, there is no better option

😅

[rotund token]

haha wouldnt go that far

we have a lot of UI issues at work though

so i've been trying to design a system that avoids them

(at least the complaints i hear our UI guys complain about)

[rustic rain]

I have come up with one way

that uses Model-View-Presentation pattern

and uses URL global events to manipulate UI

and I also have a plan to burst compile it

[rotund token]

i consider my implementation a variation of mvp

[rustic rain]

Here's what I mean

    [StateUri(URLUtility.BuildMenu)]
    public class BuildMenuPresentation : BasePresentation, IComponentData
    {
    }

Where

    public static class URLUtility
    {
        public const string OpenMainMenu = "MainMenu";

        public const string OpenMainGameScreen = "OpenGameMain";

        public const string UpdateUI = "UpdateUI";

        public const string HireMenu = "HireMenu";

        public const string BuildMenu = "BuildMenu";
    }

so if event with that string comes up (which can be called with EntityManager from any point in World)

UI will be enabled

with this, my presentations never have to rely on any other presentation

or even know about them

[rotund token]

neither does mine

except i use my K system

        private struct KeyWindow
        {
            [K("UIStates")]
            public byte Key;```

    {
        [SerializeField]
        [K("UIStates")]
        private byte[] defaultStates;```

[rustic rain]

key could work as well

internally

I want to use it as Hash of string

[rotund token]

just appears like that in UI

[rustic rain]

nnah, I don't want to rely on indices in any way

[rotund token]

you dont reply on indices

its a dictionary string -> int

it's all data driven

you never use the index yourself

[rustic rain]

well anyway, my plan is to create a huge int array for each URL that exists and then when event comes up - get hash and do comparison in Burst

[rotund token]

we used hashes in our project

and it's a bit of a nightmare

to debug

[rustic rain]

🤔

[rotund token]

you have an issue debugging all you get is a hash

[rustic rain]

that could be release only

[rotund token]

break point you see -234568234

we have 8016 hashes

someone ended up code genning an enum then duplicating it on a component so they could inspect it...

so gross

so we have an enum anyway..........

anyway this might not apply to you

it's a totally legit strategy but this is why i've been a bit burnt by it

i only use this K indexing for UI/states which I don't expect to be that many

and they shouldn't be changing once created

i have a scriptable object auto indexing system for actual objects in the game

with protection against git merges

basically unbreakable as far as i can tell

[rustic rain]

how do you manage states this way anyway?

[rotund token]

which part?

it's all in my core library

https://gitlab.com/tertle/com.bovinelabs.core/-/blob/0.11/BovineLabs.Core/Keys/K.cs
https://gitlab.com/tertle/com.bovinelabs.core/-/blob/0.11/BovineLabs.Core/Keys/KMap.cs

K is just a FixedHashMap stored in a SharedStatic

so it can be accessed from burst or mono

[rustic rain]

I'm talking about editor window in which they appear and you can edit them

[rotund token]

oh i have this whole generic settings UI going

basically just inherit from : Settings in my project

and it'll generate a settings asset for you

and it'll setup this window

actually just ISettings + scriptable object

https://gitlab.com/tertle/com.bovinelabs.core/-/tree/0.11/BovineLabs.Core.Editor/Settings

it's really nice

I have a specific base settings object for K settings so literally all i implement is this

    {
    }```

and the whole thing is done

i have a new K usable value

attribute via
[K("UIStates")]
[SerializeField] private byte value;
for serialized data

use it in code via if you want a LayerMask similar API
K<UIStates>.NameToKey("menu");
even in burst

i'm all about the usability and tooling

[hushed lichen]

I was sitting with an issue yesterday and I can't think of any other channel to mention it - not that I'm expecting much visibility here from Unity devs, simply too much activity.
But in MonoBehaviour land, it's fairly simple to get a GO's properties in a new window which is really useful for comparing different GOs. In DOTS land, I haven't found a way of getting an entity's properties in a separate window so comparing different entities, or entities to the contents of a dynamic buffer, is very much an exercise in frustration. Would be nice to have a pop-out properties window like GOs have 🙂

[rotund token]

there are some tools for this, like this will popup a window in a query

you can also pin 2 inspectors still

[hushed lichen]

OK, I might just be a little bit blind and made a big ol' box of text lol. Egg on my face 🙂

[rotund token]

like you can also still pin entities in the inspector to compare side by side

i do wish there was a bit of a better workflow for multiple inspector windows

[hushed lichen]

Thanks tertle ❤️

[rotund token]

its always been a bit of a pain to pin and unpin stuff

i've been meaning to write a nicer way of doing this at some point

just not sure what i want

i should probably google around and see if anyone has done something, not exactly dots related

so i'm sure someone has wanted something more before

(for the record i don't disagree with your original point, i'm sure everyone would like better tooling but they do seem to be doing work on this. just pointing out a way you can do a comparison for now)

[hushed lichen]

I thought we had no tooling for it hence the egg on my face. Having something is vastly better than having nothing.

[rustic rain]

I don't really get it. So you create generic type. but what is KSettings?
can't find it in your Core/Settings folder

[rotund token]

its in the keys folder

https://gitlab.com/tertle/com.bovinelabs.core/-/blob/0.11/BovineLabs.Core/Keys/KSettings.cs

[rustic rain]

So, basically it's runtime enum?

[rotund token]

yeah K is basically an enum replacement as well as a UnityEngine.LayerMask replacement in 1

it came about as a challenge of creating a way with burst I could replicate this
https://docs.unity3d.com/2022.2/Documentation/ScriptReference/LayerMask.NameToLayer.html

converting a string to an int via a static method from anywhere even in burst

reading from a settings file

it just evolved to be generic and support unlimited types

[rustic rain]

interesting

[rotund token]

i'm not suggesting you implement this in your project or anything

no one's really ever shown much interesting in it except for the couple of users testing my Game framework

but that's because they've used it via the framework

i'm just kind of showing off how i'm trying to make things data driven

[rustic rain]

yeah, I get it

I'm interested

just currently extremely busy with little windows of free time 😅

[rotund token]

yeah i know the feeling

i was hoping to get a bunch of personal project work done over xmas

barely did anything

(also a bit mentally exhausting finally getting some time to work on project only to spend a day trying to debug why burst is corrupting)

[devout prairie]

just realised i don't seem to be getting collision events

since upgrading to 1.0

anything obvious i might not be aware of?

i did port my stateful collision system code over to reflect the updates in the physics samples version

but it seems it's not running ( ie i'm guessing not seeing any of the required StatefulCollisionEvent's )

[rustic rain]

is it possible to add more values to settings in runtime?

for example by loading new assembly?

to specific settings I mean

[rotund token]

the values are loaded at runtime

you'd have to be careful about thread safety - load them before you start using any in a job

        private static void LoadAll()
        {
            var kvSettings = Resources.LoadAll<KSettings>(string.Empty);

            foreach (var setting in kvSettings)
            {
                setting.Init();
            }
        }```

atm i just load them via Resources - they're not baked or anything

its not the greatest approach and something i want to consider at some point

but yeah there's nothing stopping you loading new values at runtime

it's just a hashmap

[rustic rain]

any example of Init implementation?

[rotund token]

https://gitlab.com/tertle/com.bovinelabs.core/-/blob/0.11/BovineLabs.Core/Keys/KSettings.cs

K<T>.Initialize(this.Keys);

is all it does

which just creates a hashmap
Map.Data = new KMap(kvp);
https://gitlab.com/tertle/com.bovinelabs.core/-/blob/0.11/BovineLabs.Core/Keys/K.cs

[rustic rain]

so, for each generic implementation of K<T>
there is SharedStatic assoiciated

And how is it used in Burst then?

[rotund token]

because shared statics are inherently generic

    {
        private static readonly SharedStatic<KMap> Map = SharedStatic<KMap>.GetOrCreate<KMap, T>();```

this code here is basically the trick to the entire thing

turns out shared static just naturally work perfectly for this

[rustic rain]

I mean, how do you use it in Burst code?

[rotund token]

var key = K<UIStates>.NameToKey("menu");

var key = K<UIStates>.NameToKey(config.menu);

etc

shared statics work in burst

    {
        private static readonly SharedStatic<KMap> Map = SharedStatic<KMap>.GetOrCreate<KMap, T>();

        /// <summary> Given a name, returns the user defined value. </summary>
        /// <param name="name"> The name. </param>
        /// <returns> The value. </returns>
        public static byte NameToKey(FixedString32Bytes name)
        {
            if (!Map.Data.TryGetValue(name, out var key))
            {
#if ENABLE_UNITY_COLLECTIONS_CHECKS
                Debug.LogError($"{name} does not exist");
#endif
            }

            return key;
        }```

this is basically the entire code

[rustic rain]

I see

I don't like the idea of using string in code though

I prefere to wrap all around const

[rotund token]

you can pass a const

thats fine

or pass in a config

[rustic rain]

I know, just similiar thing basically

of what I use atm

[rotund token]

it's actually a MiniString (16byte non null terminated string)

because FixedString32Bytes is a tad too big

so max string size is 15

i thought that was long enough i'd rather double the state size

[rustic rain]

I wonder if Burst can convert to Hash during compilation

[rotund token]

(since I used a fixed hash map so i don't have to worry about allocations)

[rustic rain]

smth like

"string".GetHashCode()

[rotund token]

if each 'string' was a Type

it oculd

not sure you'd want to do that though

[rustic rain]

I'm fine with hash

in my implementation there is going to be an array

with real strings

[rotund token]

burst just has type -> hash

Unity.Burst.BurstRuntime.GetHashCode32(type)

[rustic rain]

which index will equal index of hash in array

[rotund token]

hence the random suggestion

[rustic rain]

nah, hash of specific string

not type

anyways, I'm looking forward some simple code gen instead

for now I have this little editor window which shows all existing URLs

[rotund token]

there are built in burst compiled fixedstring -> hashcode methods

if you needed

but it sounds like you're more going for compile time version of it

[rustic rain]

not really

it is indeed using reflection

but only on system creation

so basically

it queries for all Attributes in UI specific classes

and parses them as URLs

this way I can load as many assemblies

in runtime

and all URLs will be parsed

but I'd rather want

so it works more like input system

where I create asset with values

and then use their definitions in code

I'v yet to figure a way to do it. One way I can codegen C# code with all const strings

not sure if that's the way though

[rotund token]

ah i see why you were interested in the above

[rustic rain]

or whether I should even use stirng at this point

[warm panther]

Q: When do I use ISystem, when do I use SystemBase? I... don't get the difference anymore, other than some API calls differing.

https://forum.unity.com/threads/isystem-vs-systembase.1357655/ Seems like I am not alone 😄

[rustic rain]

ISystem gets bursted, SystemBase doesn't

if you use burstcompile attribute

SystemBase can store managed references, ISystem can't

[misty wedge]

I think you can store managed references in a non-burst compiled ISystem?

I don't think I've tried it though

[rustic rain]

no

[misty wedge]

What happens?

[rustic rain]

it throws error on init

ISystem's are stored in unmanaged way

managed struct will break it

[misty wedge]

Weird that they don't have a compile error for that

I guess I never tried it 🤷‍♀️

[warm panther]

Can I schedule jobs from ISystem?

[rustic rain]

yeah

while bursted too

[warm panther]

kk, thanks!

[misty wedge]

When will this ever go away

[warm panther]

I have given up. 🙂

Q: Are there equivalents to:
Bounds.Encapsulate
and
Bounds.IntersectRay
in DOTS / Unity Mathematics? (for Unity.Mathematics.AABB)

[warm panther]

Question: The Query in this is empty, but such an entity definitely exists. Is there something I'm doing wrong?
I suppose this is run before the subscene is loaded.

        public void OnCreate(ref SystemState state)
        {
            Debug.Log("Building Mesh List");
            _meshes = new NativeHashMap<uint, NavMesh>(100, Allocator.Persistent);
            foreach (var (mesh, world) in SystemAPI.Query<NavMesh, PhysicsWorldIndex>())
            {
                Debug.Log("Bound mesh");
                _meshes[world.Value] = mesh;
            }
        }

I'll try some require for update shit or something.

[misty wedge]

The scenes are also loaded via systems, so the scene (usually) hasn't loaded in the OnCreate of another method

The easiest thing to do is just RequireForUpdate a component that is in the scene

Then you can do your initialization in OnStartRunning

[warm panther]

Yeah.

[misty wedge]

If it's performance critical initialization I would add a bool or something to check if you have initialized already, unless your system never stops running

[warm panther]

Got it to work.

It is literally copying a few pre-generated NavMesh components into a native array.

For easier lookup.

(and later, for some extra processing)

[misty wedge]

Why not just store the entity reference to the navmesh and use a component lookup?

[warm panther]

The entity holding the NavMesh and the entity that the pathfinding operates on are separate.

[misty wedge]

Yes, that's what the component lookup is for

[warm panther]

So I save a lot of boilerplate this way.

(I think)

[misty wedge]

I'd argue it's actually more boilerplate 😅

[misty wedge]

But it depends on how your project is setup

Ah, you are using the physics world index

Then it's fine I suppose

[warm panther]

I can work on consolidating this later, still not sure how to add dynamic avoidance data and all. (could be that there's a system that edits a dynamic representation of the nav meshes). These are just the pre-baked ones from static geometry.

It's all I need for now.

I already dislike BlobAssets. 😛

[misty wedge]

I recommend you eventually move this to a job though, since pathfinding is usually computation heavy

[misty wedge]

I love them ❤️

[warm panther]

Yes I will jobify this.

This is just a step so I can test my new pathfinding algorithm, should be much faster thanks to how much more sparse and precise the nav mesh data is.

[warm panther]

Only a mother can love this code. 😄

[misty wedge]

It depends on how you have it set up. I use blobs to convert authoring time scriptable object to runtime blob assets for use in jobified code, and it's really not that bad

This is the method the scriptable objects implement

The blob builder part exists only once

and the scriptable objects can just write their data to the struct

[warm panther]

Yeah I don't like this pattern at all. 😅

[misty wedge]

I love it, so much easier to make nice editors and then still have incredibly fast runtime data

And blob assets give you much more complex data layout than native containers

[warm panther]

I'll probably end up writing some extension or utility function to convert IEnumerable<T> to BlobArray<T> or something.

This should be at best 1 line in the Baker.

[misty wedge]

It already kind of exists, but it wants an array

[warm panther]

Omg.

Do I still need a Root first?

[misty wedge]

Yes, since it wants a ref to a BlobArray

(which can only exist on a constructed root)

[warm panther]

M'kay. 🙂 But this is very helpful.

[misty wedge]

I didn't like them at first too, but now I basically use it for all immutable data

A big upside of them is also that they are very easy to serialize

[warm panther]

So I guess it can look like this. It's somewhat better.

How do you get your scriptable objects at bake time? Or do you keep a reference on the GameObject that the Baker's Behaviour is on?

[misty wedge]

I don't bake the blobs, I convert them at runtime

The scriptable objects can be overwritten by mods

[warm panther]

That's... kind of amazing, not gonna lie.

Sweet idea!

[misty wedge]

I don't think it's that special of an idea 😅

[warm panther]

So you have a System that Resource.LoadAll<T>'s the SOs and turns them into Blobs?

[misty wedge]

They are loaded via addressables, then converted

[warm panther]

Even better.

[misty wedge]

all the blobassetreferences are added to their respective dictionaries

[warm panther]

Cool!

[misty wedge]

which can be indexed by a GUID type which just stores 4 ints

[warm panther]

Yeah that's kind of how I do it with my nav meshes, but the ID is literally the physicsworld for now.

[misty wedge]

The more "out there" part of the system is the dependency injection to more easily pass them to jobs

the Blobs then have a dictionary-esque indexer that takes the GUID

and returns the blobassetreference

[warm panther]

This injects into what?

[misty wedge]

Into a system

[warm panther]

A Mono Behaviour or a Syst... ok 😄

[misty wedge]

SystemBase or ISystem

[rustic rain]

wait what?

what is this?

[misty wedge]

It's a custom attribute

basically injects a NativeHashMap<GUID, BlobAssetReference<T>> into the system

(for a specific scriptable object type)

[warm panther]

Q: What may be possible causes of this? I can't find the entity in question, so it's really weirding me out a bit.

[misty wedge]

It's 50/50 if the error actually matters

I think I also get this but nothing broke, not sure though

[warm panther]

Very cool, where in the PlayerLoop or Systems do you do this actual injecting? Or is it code generation?

[misty wedge]

It just uses reflection

If that ever becomes a bottleneck I'll switch to something else, but at the moment it takes less than a millisecond

Since you don't have a million systems lying around

[warm panther]

Ok, seems like I'm kind of unaware when the code relating to attributes is actually executed. (despite having written a couple myself)

[misty wedge]

The attribute doesn't do anything, it's just there for the reflection to find the fields it needs to inject

[warm panther]

So where and when do you run the reflection/injection? 😄

Just looking around for ideas and best practices.

[misty wedge]

It runs in a system after having loaded the scene for the the server / client

[warm panther]

I see. 🙂

[misty wedge]

What's nice with runtime conversion is you can also reconvert the blobs at runtime so you don't always have to re-run the game if a scriptable object changes

[warm panther]

How would you serialize a HashMap in a BlobAsset?
var lookup = new NativeHashMap<float3, Node>(nodes.Length, Allocator.TempJob);

This is also one of the reasons why my pathfinding system copies all the components, it's a postprocessing step it needs to do, but I'd love to just have this stored in the asset.

[misty wedge]

I use this: https://github.com/bartofzo/BlobHashMaps/blob/master/README.md

I made some changes to it though since it violates some parts of blob usage

[warm panther]

(and later turn it into half3 or something depending on whether that speeds stuff up - but the meshes are super small now, but there will be about 200~1000 in parallel use by up to ~10k agents - not all exactly at the same time, fortunately)

[misty wedge]

A half3 will be slower than a float3 iirc, since it needs to be convert back. It just saves some memory

[warm panther]

Yeah there's no distance metric for it... or even basic arithmetic. But memory transfer speed is usually the bound here.

I need to see how the GetHashCode works though, thanks for "reminding" me.

It's fast (maybe), uses ushort representations.

[misty wedge]

Yes, but it converts those to floats for calculations. If you are truly memory bound it might make a difference

[warm panther]

I wonder if I need it at all, I could use mesh index with these new data structures.

In modern computing, at least as Unity ECS has taught me, recalculating is often way faster than storing and loading.

[misty wedge]

It depends on the calculation and the amount of memory stored 😅

[warm panther]

Talking an order of magnitude or more.

[misty wedge]

That's one performance advantage of blob assets too, you are less likely to have cache misses

at least compared to data layed out with pointers

[warm panther]

Yes if it all fits into one or two cache lines, you are cool.
But these mesh structures don't fit into the L2 cache very well, so I'd rather keep them as small as possible so as much of it as possible fits.

[hybrid jay]

Anyway to turn off burst outside the editor?

The editor keeps crashing on startup

[hybrid jay]

is that in a file outside the editor?

[misty wedge]

It's in the project settings

[hybrid jay]

yeah but is that easily accessible?

[warm panther]

Yes.

[misty wedge]

It's two clicks, so I'm not sure what you mean

You'll need to rebuild the project though

[hybrid jay]

i cant open Unity

[warm panther]

There is a ProjectSettings directory. You can open the asset for the respective setting there.

[misty wedge]

Tried clearing the library folder?

It's unusual for the editor to immediately crash like that

[warm panther]

BurstAotSettings_StandaloneWindows.json for example

@misty wedge Thanks so much once more for the inspiring conversation and advice. 🙂 I'll take a break and get back to coding.

[hybrid jay]

huh, cant find that

[misty wedge]

No worries, glad it helped you 👍 Note that this is just an approach that I came up with so your mileage may vary

[misty wedge]

What ECS version are you on?

[hybrid jay]

latest

[misty wedge]

Odd

This is the contents of the file

{
  "MonoBehaviour": {
    "Version": 4,
    "EnableBurstCompilation": true,
    "EnableOptimisations": true,
    "EnableSafetyChecks": false,
    "EnableDebugInAllBuilds": false,

    "CpuTargetsX32": 6,
    "CpuTargetsX64": 72,
    "OptimizeFor": 0
  }
}

It will probably not help you though, since that only disabled burst for builds

(afaik)

Not sure where unity stores the enable compilation flag for burst, maybe in editor prefs or something

[hybrid jay]

just doing a library deletion

will try adding the json after

though yeah, probably wont help if its only for builds

oh, good the library fix worked

[hybrid jay]

This is actually the most useless error

guid = 29242:0:00000000:00002710, count = 1, obj = StarBase (UnityEngine.GameObject)

The prefab has unique components that none of the other ones have (including a baker with a unique tag component)

So i've got no idea how theres something with the same guid

and its not a subscene object issue as that prefab is not even in a scene and is only spawned later

[hybrid jay]

Anyone have any idea why this bit of the Netcode Package is producing this error?

InvalidOperationException: The BlobAssetReference is null.
Unity.Entities.BlobAssetReferenceData.ValidateNotNull () (at Library/PackageCache/com.unity.entities@1.0.0-pre.15/Unity.Entities/Blobs.cs:279)

I havent touched any of the prefabs and i've got no idea how these blob assets are being made

Weird errors like those i seem to always get when using Dots

for future reference for anyone else dont add the ghost authoring component on gameobjects before making them prefabs

apparently that breaks random stuff

the DOTS experience in a nutshell

[rotund token]

Are you trying to instantiate during baking?

[barren scaffold]

im so new to dots idk what dots even is.
https://hatebin.com/cemepquqmk

can you tell me what this script does and how it works?

[hybrid jay]

nope, was just a very weird bug

[hybrid jay]

Thats more of a question for PraetorBlue since they gave you it. But not gonna lie since you didnt even know what a dictionary was in #💻┃code-beginner any explaining just wouldnt make sense to you. I'd recommend learning more of the C# basics first.

[barren scaffold]

ik c# i just forget everything until i have to use it and then i have to learn it again lol

[rotund token]

anyone ever looked at editor iteration profiler?

i really wanted to know what the slow domain was about

death by 10000 cuts

1.7seconds on burst and job init, 1 second on InitializeOnLoad editor stuff

approaching a second to reload 5 tiny subscenes

was hoping for some low hanging fruit

setup type cache another second

loading assemblies themselves 1.8 seconds

repaint all UI, 900ms

[covert lagoon]

I want to know why after creating an empty project by manually creating a directory with Assets and ProjectSettings subdirectories, installing URP doubles Unity's after-start-up RAM usage and installing ECS packages doubles the time Unity takes to start up.

[stone osprey]

Since burst code can not reference classes n stuff... what do you think about bevy handles approach ?

It works kinda like this:

public class Handle<T>{
    public static List<T> items;
    public Handle<T> Add(in T t){ return new Handle<T>{ Index = items.Add(t); } }
    public T Get(in Handle<T> t){ return items[t.Index]; }
}

var goHandle = Handle<GameObject>.Add(new GameObject()); // Handle stores a List of all gameobjects and basically returns their index
myEntity.AddComponent(goHandle);

Entities.ForEach(ref Handle<GameObject> handle) => {
   var gameObject = handle.Get();   // 
   gameObject.... // Do something with gameobject and its burst compatible since the entity itself does not contain references :) 
});

So each entity basically manages their managed resources with handles. Handles point towards a list entry where the pointer/class is stored at. And when we need to acess it, it can be easily acessed in a burst friendly way.

Is this usefull ? Or does this have disadvantages ?

[rotund token]

i don't get what this has achieved?

gameObject.... // Do something with gameobject and its burst compatible since the entity itself does not contain references :)

you can't use a gameobject in burst

this hasn't changed anything

entities are allowed to reference gameobjects, burst is not

you can literally just do this
EntityManager.AddComponentObject<GameObject>(entity, go)

Entities.ForEach((GameObject go) => {}).WithoutBurst().Run();

this is legal code

[stone osprey]

Hmmm alright... i think i missunderstood that.

Besides that, would this make sense for ECS in general ? I saw bevy ( rust engine/ecs ) use something like this. And i wondered if its considered usefull or good.

Like it basically means that each entity requires one more additional lookup and the list that stores the handles is also loaded into cache each acess... I also wondered if its compatible with ECS terms.

[rustic rain]

Burst can only work with native unmanaged memory

GameObject class is managed

But some internal cpp parts aren't

There is ptr to them, but I dout it's any use

[rustic rain]

Unity made tranform access job to burst transform code, so that's as far as it can go

[rotund token]

where are you calling this code?

this should be created/called in your Connect method

[winter depot]

What is SystemAPIQueryBuilder? Is it something not yet utilized?

[covert lagoon]

Looks like it's like EntityQueryBuilder but you won't have to pass the system's this to the Build method.

[winter depot]

That's what it looks like to me, but incomplete?

[rotund token]

How so?

What's missing from it

[winter depot]

Maybe I am initializing it wrong or something, but I get a crash every time I attempt. One attempt that didn't crash said something about failing code generation

[covert lagoon]

The code in this test is supposed to work apparently.

I see SourceGenTests.CheckForNoError<SystemGenerator>.

[winter depot]

To be fair my unity crashes 50% of the time on domain reload anyway so could be anything

[rotund token]

Hmm I nearly use it exclusively

and not had an issue

[winter depot]

Do you mind showing a code example?

[rotund token]

sure

i have 41 of them, here are a few examples

[winter depot]

Hmm, looks exactly like what I've attempted. Maybe ill try regenerating some files or something

[covert lagoon]

So I'm supposed to use SystemAPI.QueryBuilder() instead of new EntityQueryBuilder(Allocator.Temp), in system OnCreate()s at least?

[rotund token]

you don't even need to use it in oncreate

you can just use it directly in OnUpdate then and not cache the query

as it'll cache it for you

[covert lagoon]

Oh right that's the point of SystemAPI.

Why do the manuals not show SystemAPI.QueryBuilder() instead then?

[winter depot]

Ok.. Its worked fine now. Sorry for the trouble,

[covert lagoon]

Well the Netcode for Entities manual also shows Entities.ForEach.

Wait no.

I'm confusing it with something else I think.

Yeah it's not the Netcode for Entities manual that uses Entities.ForEach in examples.

It's the Entities manual that uses Entities.ForEach in some examples.

[winter depot]

Well, its still usable. lol

They got some catching up to do on manuals and what have you. Having a nice holiday 😄

Btw do I still need to be on 2022.2.0b16? Or is there a more stable build that can work with the current packages

[covert lagoon]

Here the queried NetworkIdComponent is left unused. Should use .WithAll<NetworkIdComponent>() instead.

[covert lagoon]

You can use stable 2022.2 now that it was released.

I'm on 2022.2.1f1.

[winter depot]

Thank god

[covert lagoon]

I tried one of the 2022.2 betas, forgot which one, but I remember it being pretty buggy yeah.

You should try 2022.2.1f1, hopefully your problem of Unity crashing on 50% of domain reloads will disappear.

[winter depot]

Installing now, this is great news

[covert lagoon]

And NetworkIdComponent only stores a single int, why ever take it as RefRO instead of taking it by value?

[rotund token]

why not 🤷‍♂️

[covert lagoon]

More typing for no benefit.

[viral sonnet]

RefRO for a single int is indeed not that great. it can have its purpose when the access can get vectorized but in this case i doubt it

[covert lagoon]

Oh wait I don't want to cache the query when I'm creating it just to pass it to RequireForUpdate in OnCreate.

[winter depot]

Entities that use manually registered IDs don't need to have a RenderMeshArray component, while entities that use array indices must have one. Entities Graphics 1.0 entity baking uses RenderMeshArray. This is nice, as it should speed up the inspector window and make things more manageable. The confusing part for me is that RenderMeshUtility.AddComponents() requires a render mesh array by default. You can pass an empty one, but I would think the method would have an option where its unnecessary to pass.

[viral sonnet]

oh what, math.slerp only has quaternion as parameter.

that's great when the Vector3 source consists of a call to Vector3.INTERNAL_CALL_Slerp(ref a, ref b, t, out vector3);

oh well, gonna have to go in a roundabout way through a lookAt quaternion

[void girder]

I'm noticing that calling SetSharedComponentFilter() on an EntityQuery adds that shared component data to the EntityManager.GetAllUniqueSharedComponents() nativelist output. Anyone getting this behavior? Is it a bug?

[rotund token]

this seems expected

GetAllUniqueSharedComponents just returns all unique components an EntityManger is aware of atm

regardless an entity has the component or not

what it looks like in the inspector?

[deft ridge]

runtime

[tawdry mulch]

still the same when set to runtime

[covert lagoon]

Show all the components it has

[deft ridge]

this i am fine

[deft ridge]

frameDebuger

[tawdry mulch]

haha when i remove the objects from the subscene, there are 36 calls but this one has 6

it's completely ignoring whatever is in the subscene

[covert lagoon]

URP default?

[tawdry mulch]

nope

[covert lagoon]

Universal RP/Lit?

[tawdry mulch]

not installed

[covert lagoon]

You need the SRP.

Either URP or HDRP.

Built-in render pipeline won't work.

[tawdry mulch]

christ

[deft ridge]

🤣

[tawdry mulch]

oops i thought entities graphics is a render pipeline

this is my bad

because i remembered we used hybrid renderer

[rustic rain]

Hybrid Renderer relied on SRP as well

[scarlet inlet]

Anyone would be so nice to share their thoughts about my problem here? https://forum.unity.com/threads/examples-of-using-dots-ecs-1-0-with-unity_disable_automatic_system_bootstrap_runtime_world.1380765/#post-8698701

[rustic rain]

well, you are meant to create import entities only through subscene

or roll your own runtime creation pipeline (slow)

[scarlet inlet]

in the last post I showed a not perfect yet code to load a subscene in a custom world

[rustic rain]

Try using ICustomBootstrap

[scarlet inlet]

but I have asked if there is a better way to do so

[rustic rain]

to create your own default world

[scarlet inlet]

the code I pasted in the thread shows that I have already a custom world

[rustic rain]

you don't need either of those directives

[scarlet inlet]

I need to update the custom world myself, the point is that I am using UNITY_DISABLE_AUTOMATIC_SYSTEM_BOOTSTRAP and no explicit update must be done (unless I do it manually)

[rustic rain]

You can simply use ICustomBootstrap and not add any systems

except for scene systems for example

[scarlet inlet]

but then I have to call Update() manually to run the scene system

[rustic rain]

I wonder if Unity has enum to filter SceneSystem

[rustic rain]

no?

[scarlet inlet]

while (SceneSystem.IsSceneLoaded(customWorld.Unmanaged, sceneEntity)
                == false)
            {
                customWorld.Update();
                await Task.Yield();
            }

[rustic rain]

they exist in InitializationSystemGroup

which you can create manually

or automatically

such main system groups are attached directly to GameLoop

[scarlet inlet]

anyway I had some troubles, i.e. the code works, but not with IL2CPP for example. For some reason the scene doesn't load in an IL2CPP client but it does in a mono client

[rotund token]

i would be very doubtful if you could do runtime baking properly, , but even if you could it would be so much slower than just writing your own quick conversion system without the tracking overhead

I am not really sure about how to create entities from unity prefabs without needing a subscene
you're not really meant to

anyway how are you creating your worlds?

even if you UNITY_DISABLE_AUTOMATIC_SYSTEM_BOOTSTRAP you should generally still call
DefaultWorldInitialization.Initialize("worldName")

and implement ICustomBootstrap to manage the world

this is required to setup Entities Journaling, profiler and other tools

        {
#if ENABLE_PROFILER
            EntitiesProfiler.Initialize();
#endif

#if (UNITY_EDITOR || DEVELOPMENT_BUILD) && !DISABLE_ENTITIES_JOURNALING
            EntitiesJournaling.Initialize();
#endif```

personally if you have an existing project with custom workflow like this, i would recommend just sticking with 0.51 (that's what we've done) as you are not really benefiting from the pain of upgrading

Anyway I guess up answer your question, il2cpp is probably stripping your bakers as there will be no references to them

[mild ledge]

If I create a NativeCollections with a temp allocator inside a method, do I need to dispose it at the end of the method or no?

[rotund token]

No

Temp does not need disposing

[mild ledge]

Thanks for confirming

[olive kite]

I'm using a collisionWorld.CalculateDistance(pointDistanceInput, ref targetsFound) and trying to determine if a target has a particular collider tag, would collider tags need to be queried and passed in the system to access that information or is there any way to get that from the DistanceHit?

oh, CustomTags in Material, i see

[strange wagon]

I call it via UI from client. I trying to use Manually Listen/Connect but also I have custom NetCodeBootstrap : ClientServerBootstrap class. Should I delete my bootstrap if I use manually connect?

I'm looking at the Network Racing Sample and it has both an override of NetCodeBootstrap and a manual connection to ServerConnectionUtils

[covert lagoon]

There's no default world with Netcode anymore? Just the client and server worlds?

What does ClientServerBootstrap's Initialize method do with defaultWorldName then?

Oh it just does nothing with it.

[tawdry mulch]

how are we integrating the new InputSystem into ISystem?

[rustic rain]

either store input actions map on component or somewhere else

and call managed code in OnCreate

or don't use ISystem at all

[viral sonnet]

just sample inputs in SystemBase and save them in a struct. InputSystem generates a managed class or has managed calls so no real way around it that i'm aware of.

[tawdry mulch]

😭 okay thank u

Send Messages doesn't seem to work on objects in a subscene :/

[viral sonnet]

why would it? GOs and MBs are not present in subscenes. it would only work in editor when the scene is open

[tawdry mulch]

Well, I've tried Send Messages, Invoke C# Event and generating the action script class. In every case, I can't retrieve the input :/

I am even trying it on a MonoBehaviour component and it still isn't working

Oh it seems MB doesn't start at all in a subscene. SystemBase works.

unsurprisingly, it doesn't work in ISystem either

[tawdry mulch]

which means this isn't possible

[rustic rain]

well, I did it

So can you

[tawdry mulch]

how'd u do it?

I get this error

ArgumentException: The system Controller cannot contain managed fields. If you need have to store managed fields in your system, please use SystemBase instead. Reason: Controller.<TestPlaygroundInput>k__BackingField is not blittable because it is not of value type (TestPlaygroundInput)

[rustic rain]

public class Lul : IComponentData { public InputActionsAsset kek;}

[tawdry mulch]

hurh.. okay ill try that

[tawdry mulch]

it says the input actions has to be non-nullable :/

[rustic rain]

ComponentObject

[tawdry mulch]

how? there's no monobehaviour

[rustic rain]

AddComponentObject

ManagedComponents are managed separately

[viral sonnet]

@tawdry mulch take a look at how Rival does it: https://github.com/Unity-Technologies/rival-samples/blob/master/Platformer/Assets/Scripts/Player/PlatformerPlayerSystems.cs

[tawdry mulch]

that one uses systembase

[tawdry mulch]

the errors dropped but are u doing something like this?

[viral sonnet]

so? there's not much use for a non-burst compiled ISystem

[rustic rain]

AddComponentObject

[tawdry mulch]

yeah but i thought its cool haha, ill use systembase as a last resort

[rustic rain]

EntityManager.AddComponentObject

[tawdry mulch]

Entity has no AddComponentObject

[rustic rain]

I fixed typo

[tawdry mulch]

that method takes a componentData
public void AddComponentObject(Entity entity, object componentData)

how do i even give it that from inside ISystem?

[rustic rain]

create it

[tawdry mulch]

do i put the input action callbacks in my authoring script?

[tawdry mulch]

this way kinda sucks too. he's if chaining all of his input actions

[void girder]

Look at past messages it seems like it's difficult to spawn additional entities with Baking Systems. How are most people doing it atm then?

[rustic rain]

no, you can create them out of anywhere

[tawdry mulch]

the same as how you do it always

like this

[tawdry mulch]

do you have an example? im at my wits end :/

[rustic rain]

new DefaultInputActions();

[tawdry mulch]

As in these callbacks though

}
  PlatformerInputActions inputActions = new PlatformerInputActions();
  inputActions.Enable();
  inputActions.Player.SetCallback(this);
}

public void OnThrottle(InputActions.CallbackContext ctx) {
  Debug.Log(ctx);
}

[rustic rain]

What about them? You store them on your inputActions asset

[tawdry mulch]

But this is how it's usually done?

public class Controller : MonoBehaviour, TestPlaygroundInput.IPlayerActions {
    TestPlaygroundInput TestPlaygroundInput { get; set; }

    void Start() {
        print('start');
        this.TestPlaygroundInput = new TestPlaygroundInput();
        this.TestPlaygroundInput.Enable();
        this.TestPlaygroundInput.Player.SetCallbacks(this);
    }

    public void OnThrottle(InputAction.CallbackContext context) {
        Debug.Log(context.ReadValue<float>());
    }
}

the asset contains the TestPlaygroundInput class

you create an instance of that class in your MonoBehaviour script and tell it which methods to call'

[rustic rain]

store you managed objects on managed component

that LulKek example I send earlier

btw

the exact way you use it

is not possible with ISystem

neither with SystemBase

[tawdry mulch]

ah i thought so

[rustic rain]

you can only register them

manually

[tawdry mulch]

the only way is that shitty if chain :/

[rustic rain]

like inputActions.UI.Cancel.performed += MyMethod;

[tawdry mulch]

oh that can work?

on ISystem?

[rustic rain]

yes

I don't get

why you need ISystem here

though

[tawdry mulch]

because its cool, thats all

[rustic rain]

But you don't use ISystem

at all

doing that

[tawdry mulch]

yeah but the class uses the interface

imagine a codebase with 0 SystemBase

[rustic rain]

like I mentioned, you can't use it this way

[rustic rain]

there are tons of default built in ones

lol

besides

nothing wrong with SystemBase

I have tons of them for UI stuff

[tawdry mulch]

):

[rustic rain]

use them properly

ISystem is good when you work with unmanaged data

because it can be easily bursted

SystemBase is good when you work with managed data, because you can store some references inside

[tawdry mulch]

but can't you partially use Burst on this implementation?

not OnCreate but some other method?

[rustic rain]

when exactly do you want to use burst?

You don't even need ISystem to use burst

[tawdry mulch]

u dont?

then whats the point of ISystem

[mystic mountain]

You can read the values and feed them into a Job

[tawdry mulch]

so ISystem is viable and useful?

[rustic rain]

do you even know what ECS is?

[tawdry mulch]

yeah u split ur usual OOP stuff into entities, components, and system

[rustic rain]

well, ISystem is system

[tawdry mulch]

yup

more [BurstCompile] = better yes

[mystic mountain]

Since you're writing from the input actions values, it needs to access managed memory, thus it needs to be in a SystemBase. But you read the values and put it into a job that is bursted if you want 😅 Then everything doesn't need to be bursted either.

[tawdry mulch]

sounds good

oh and another reason to use ISystem is reduced SourceGen compilation time

[viral sonnet]

SystemBase goes through the same codegen

[tawdry mulch]

the docs says otherwise

[viral sonnet]

no idea what they are referring to. it's very likely it's because of Entities.ForEach codegen which is indeed a problem. but that's totally optional.

just checked to confirm. there's no difference between ISystem/SystemBase codegen when all you do is have a queryBuilder and schedule a few jobs. apart from a few single lines the output is the same.

but with a single Entities.ForEach in SystemBase codegen takes longer. it's the reason why idiomatic foreach was introduced

[proud jackal]

Enzi is right :3

[viral sonnet]

yay 🙂 can you maybe relay that information for the docs? increased SourceGen compilation time. to increased SourceGen compilation time when using Entities.ForEach (or something like that) here: https://docs.unity3d.com/Packages/com.unity.entities@1.0/manual/systems-comparison.html

[tawdry mulch]

i see, thanks!

[tawdry mulch]

Do you happen to know why they needed to create a uint fixedTick = SystemAPI.GetSingleton<FixedTickSystem.Singleton>().Tick; when they have already set this attribute [UpdateInGroup(typeof(FixedStepSimulationSystemGroup)]?

[viral sonnet]

to get the actual tick which is used for some inputs. it prevents double jumping in case more FixedUpdate ticks are occuring in a single frame

remember that FixedUpdate can happen multiple times in a frame unlike Update

[hot basin]

do we know when 1.0 will be released? I thought it would be when 2022.2 will come out

is 2022.3 LTS the target?

[rotund token]

LTS is a likely target

but apart from a different version number, does it matter if it's called pre or not

[rustic rain]

I hope for critical bug fix (mat override) very soon and then I'll switch over to Latios Transforms

[hot basin]

oh yeah, I suppose so

[rustic rain]

Can't bother waiting so much

[hot basin]

besides patches there shouldn't be anything major

[rotund token]

they've been doing their major updates every 3months

and last i heard there would be a minor update end of jan

[hot basin]

can I use released 2022.2 with current pre15 version of ECS?

[rotund token]

yes

[rotund token]

whats the issue? and what are you wanting from latios transforms

[rustic rain]

issue material overrides don't work

Latios is making his own transforms

so I want to switch to it once he is done (late jun/early feb)

[rotund token]

im aware but why the hell would you use it

[rustic rain]

Animations

And Physics

his Physics are much less boilerplate (allthough I haven't tried it in actual project)

also

no hybrid

which I am done with

I literally began to making sprite renderer using Entities graphics, but stuck because material overrides don't work

[hot basin]

OK sorry for silly questions but I'm coming back to ECS after some time. Should I use Transform aspect or any of the Transform component?

[rustic rain]

I don't like Transform aspect

[rotund token]

Aspect where you can

[rustic rain]

Transforms generally are much easier to use now

which I like

sadly Latios won't support them

because they don't fit his animations

[rotund token]

his whole framework doesn't fit entities design

the whole reason his framework exists is because he doesn't agree with the unity packages

[rustic rain]

does it?
I never dug into it, but judging from his own description and thought process (which is part of manual)

what he does is designed around pure ECS

as he points out some bad OOPish design choices with physics

but once again

[rotund token]

TL;DR – Unity.Physics and I don’t get along.
his summary of why he wrote his own physics

[rustic rain]

I never really dug in

[hot basin]

I see two conflicting answers 😄 any comments on why should I use certain approach?

[rotund token]

and then goes on a 234 page rant about it

[rotund token]

use aspect especially since the transform system might completely change

whole point is it wraps the components

you need a lot of manual checks if you use components

does world component exist? if not use local otherwise use world

the only time i use components is when i want to do low level memory operations on them

like memcpystride

    ? transforms.WorldTransforms().Slice().SliceWithStride<float3>(0)
    : transforms.LocalTransforms().Slice().SliceWithStride<float3>(0);``` for example

[hot basin]

so entity can have one and not the other component

strange

[rotund token]

atm no

atm world is always added

but in theory it doesn't need to

the aspect has world transform marked as option

and the design of the baker overrides implies it should be optional

(the overrides dont work atm except manual)

if you are a root object, having worldtransform is just wasted chunk space and processing power

[hot basin]

ok then TransformAspect it is

[hot basin]

should I make "everything" into aspect or they have a downside?

[rotund token]

you mean your own stuff?

[hot basin]

yes

[rustic rain]

not really, but you can if you want to

Aspect is just a layer between Logic and Data

which you can use for convinience

so use it as you like

I only use them when amount of components is large or reusable

[hot basin]

but I assume I shouldn't abuse it because of getting data I don't need?

[rotund token]

definitely has downsides of bringing in extra components/dependencies/etc if you don't need them

[rustic rain]

yes

[hot basin]

😄

thanks a lot!

hate coming back to ECS after a while

[rotund token]

dont go away then

[hot basin]

I wish 😄

[rustic rain]

I can't bother working with OOP, so I never leave

[hot basin]

I hope I find a job which includes ECS
