[rustic rain]

or just make it more convinient

[misty wedge]

Isn't adding a [GenerateAuthoringComponent] making it more convenient? 😉

[rustic rain]

but generate authoring component is gone for a reason

[misty wedge]

It's gone because it was a mess code wise, the devs said as much

[rustic rain]

it's just not compatible with Baker workflow

[misty wedge]

iirc someone said they may add a replacement in the future

[rustic rain]

and I honestly don't understand the reason why the emphasise so much on editor live conversion

with that baking

[misty wedge]

Because it's a very simple workflow, and yields separate "authoring" and "runtime" versions of scenes, which is very powerful IMO

It just has a bit of boilerplate atm

[rustic rain]

it's way less powerful,though

it's simply shift towards ECS in conversion, with all it's downsides

[misty wedge]

I feel like if we there was a replacement for GenerateAuthoringComponent the workflow would be very similar, just instead of iterating over entities you iterate over authoring components

Similar to the old GameObjectConversionSystem except it's now a BakingSystem

[rustic rain]

that's the whole reason I'm so frustrated

I want to iterate over authoring components

it's way more convinient

[misty wedge]

authoring components != authoring monobehaviors

[rustic rain]

bruh

[misty wedge]

I'm guessing you mean the latter

[rustic rain]

not really

BakingSystem is singleton from what I understand

[haughty rampart]

is there a way to debug burst intrinsics?

[rustic rain]

judging by Manual baking systems are SystemBase

[misty wedge]

Wasn't GameObjectConversionSystem also a singleton? iirc it just wrapped the OnUpdate method in way that it ran per entity

I didn't use them much

[rustic rain]

no, it was base for inheriting

all conversion systems

[misty wedge]

Well yes, but BakingSystem is the base for baking systems

And if you make a concrete implementation of a GameObjectConversionSystem, that's a singleton

[rustic rain]

sir...

[misty wedge]

Are you not allowed to inherit BakingSystem?

[azure marlin]

I am trying to figure out how to fire a job in a system only once, and write back to a local variable once it has completed. This is what I have at the moment, but its running twice. I think this is because the job is fired off a second time the next frame, before the first has the chance two write to the local boolean. Is there a better way to accomplish this:

public partial class RunOnceSystem : SystemBase
{
    private bool hasRunOnce = false;

    protected override void OnUpdate()
    {
        if (hasRunOnce == true) return;

        Entities
            .WithoutBurst()
            .ForEach((Entity entity, in FirstPersonCharacterComponent character) =>
            {
                // ...do logic on relevent entities here only once
                UnityEngine.Debug.Log("Found a player character");
                hasRunOnce = true;
           }).Run();
    }
}

[wraith hinge]

what do you mean? burst iirc does output native pdb's, if you have a native debugger handy

[misty wedge]

I still don't see the difference whether you inherit SystemBase or GameObjectConversionSystem, in both cases there is a single instance that is running to convert your entities

[haughty rampart]

ah yes, i remember reading that. thx

oh, a lot of people were wondering if the newer build system would come back? seems like most people liked it

[rustic rain]

    /// <summary>
    /// Provides methods to control the baking process, and provides access to the <see cref="BlobAssetStore"/> used
    /// during baking.
    /// </summary>

All right, I was wrong about it

[wraith hinge]

no plans for it. it was not exactly a hair on fire problem, and it was a much bigger task than anybody would agree to put people on

[haughty rampart]

that's unfortunate. i really hope to see it return even if it's a far future from now

it had a good feel to it

[wraith hinge]

yeah it's a cool idea, but nobody really ever agreed to deal with it in the first place, some people just did it a bit and then left and then it was an orphan

[haughty rampart]

damn

[wraith hinge]

like it never got buy-in from actual platform teams

which would definitely be required to support it properly

[strange wagon]

Hi, is it ok to keep auxiliary methods in my components?

[misty wedge]

imo it's a code style thing, some people do it, some don't

[haughty rampart]

it would be more in spirit of ecs not to

[strange wagon]

no problems with performance or job system?

[haughty rampart]

not significantly

[misty wedge]

that's an understatement 😅

[haughty rampart]

there is a performance hit

[misty wedge]

I know, but it's very insignificant

[haughty rampart]

that's why i said 'not significantly'

[misty wedge]

And I said it's an understatement 😛

[haughty rampart]

don't see how

[misty wedge]

not significant could mean, "quite a bit, but not significantly"

[haughty rampart]

and it is

[misty wedge]

I wouldn't call it quite a bit

Quite a bit for me is like >20% performance loss

[wraith hinge]

what's the perf problem?

[misty wedge]

Probably even more

[wraith hinge]

oh just that you run code when you access it?

[haughty rampart]

kornflaks and i have optimized some code to the point of where we shaved off 1 quarter cpu cycle.
in contrast, i would say the hit is quite a bit

[misty wedge]

That's an insane micro optimization

[wraith hinge]

depends how many times the loop happens per frame 🙂

[misty wedge]

^

[haughty rampart]

and even in normal standards, >5% is a significant impact

[misty wedge]

I think we are arguing semantics at this point, it's all good 👍

[haughty rampart]

yeah 👍

[misty wedge]

And I definitely agree with you that it is something that should be said, especially in the dots forum, since many people like you / kornflaks / enzi are working on projects that require massive optimizations

[haughty rampart]

will burst get avx512 intrinsics at some point btw?

[misty wedge]

I just kind of groan when people are "optimizing" their project and the first thing they ask if if they should do ++i or i++ in all their loops...

[haughty rampart]

definitely ++i

[strange wagon]

I'm trying to port some of the code we wrote in Quntum. there we kept quite a lot of logic in components. not only getters but also setters

[misty wedge]

For the performance increase? 😛

[wraith hinge]

i imagine it will at some point. that said, iirc amd just released the first hardware that actually benefited from avx512? so i wouldn't really go yell at the burst team about it yet

[haughty rampart]

no, because if it's not bursted, there's no difference. but it's good for displaying intention, like all good code should

[fallow socket]

This job isn't being scheduled - it's being run directly on the main thread. It's not clear why it would run twice in this case... something something logging from a different thread? Maybe keep a counter rather than a boolean and see what happens.

[haughty rampart]

👍

[misty wedge]

That's a viewpoint I've never really heard, since you also put the "++" after the variable if you were normally adding to it, but I feel like this is also more of a code style thing, similar to how some people put the pointer in C next to the variable or next to the type

[haughty rampart]

no you don't. if you ++ a var outside of a loop, and it stands extra, you also ++myVariable;

[misty wedge]

Really? I've very rarely seen that

[haughty rampart]

you use ++myVariable always
except you index an array and explicitly need the different logic of myVariable++

[misty wedge]

Odd, iirc our university taught it the other way around

But I might be misremembering

[haughty rampart]

there's lots of code out there, most code is made by people who 'if it works it works, what's the diff'

but for correct displaying of intention, preincrement is always preferrable

[misty wedge]

I still don't see what the difference in intention is between x++; and ++x; on a single line

[rustic rain]

the value it returns

[misty wedge]

Yes, but without saving it into a value

that's the entire line

I get there's a massive difference if you are using the "return" value

[viral sonnet]

did i just wake up in the 90s? discussion about ++c or c++. are you seriously that bored.

[misty wedge]

My physics is broken so I can't do anything 😦

I'm distracting myself from my sadness

[rustic rain]

My conversion is broken

Can't do anything eithe

🥲

[viral sonnet]

lol sorry you 2 😄

[misty wedge]

someone call Mr. Unity and tell him to fix physics in netcode

[azure marlin]

I removed the log line and it still runs twice 🤔

[whole gyro]

Anyone else getting spammed endlessly with TextMeshPro errors when they try to open the entity hierarchy?

ArgumentException: FixedString64Bytes: Truncation while copying "TMP SubMeshUI [Roboto-Regular SDF Material + Roboto-Italic Atlas]"

[haughty rampart]

no

[wraith hinge]

@misty wedge what's your physics netcode symptom? my experience was that it worked, but it was a bit complicated to decide about client-only vs. interpolated vs. predicted

[misty wedge]

I don't use any parts of the simulation, just collision queries with character controllers

[whole gyro]

Is there are cap of 64 bytes for entity names? It looks like the error is coming from the fact that "TMP SubMeshUI [Roboto-Regular SDF Material + Roboto-Italic Atlas]" is longer than can fit in a FixedString64Bytes

[wraith hinge]

(actually @misty wedge let's make a thread)

[whole gyro]

Yeah, looks like it has nothing to do with TMP. Just a problem with game object names being too long:

ArgumentException: FixedString64Bytes: Truncation while copying "Some really really really really really really really long game object name"

Can somebody else test this for me just to make sure its not an issue with my setup?

1. Create an empty game object with a really long name like "Some really really really really really really really long game object name"
2. Open the Entities Hierarchy window
3. Check console for errors

[wraith hinge]

this sounds like an extremely plausible bug to me

somebody had to pick a fixed number of bytes so many things could be burstable, and they didn't have TMP when they tested

[whole gyro]

Yeah, unfortunately these game objects are created dynamically by TMP (I think) so I don't have much control over it. Might be able to work around the issue by shortening the name of the base font asset or something.

[wraith hinge]

i think we should just not error in that case

i'll forward it

[whole gyro]

Yeah, truncation is fine with me. 64 bytes is plenty in my opinion

Let me know if you want a bug report

[wraith hinge]

hopefully not, let's see

[whole gyro]

Removing those long name game objects fixed my issue btw

[tropic venture]

does the "☑ Static" setting on an object perform the same function as adding StaticOptimizeEntity script if the object is in a subscene for ECS?

[rustic rain]

it seems so
No children will exist on those entities too

[wraith hinge]

you wouldn't want them to, right? the transform system would just waste time processing them

[tropic venture]

so there's a difference if i use the Static checkbox or if i use the StaticOptimizeEntity class?

[rustic rain]

@wraith hinge any idea what is the meant way to add components to entities that are children of the one holding authoring component?

intended way

[tropic venture]

the sample scenes from https://github.com/Unity-Technologies/EntityComponentSystemSamples/tree/master/HybridURPSamples seem to go use the StaticOptimizeEntity class, and do have children

oh i guess they have GameObject children, but when converted to entities probably thats what you mean they have no children

[tropic venture]

so.... no difference then? 👆

[misty wedge]

Do you still need to use the (smaller) builds trick to build il2cpp on 1.0.0?

[sinful cipher]

So no LTS 2020/2021 support? Am I understanding this correctly?

[rustic rain]

yep

[sinful cipher]

Hmkay thanks

[misty wedge]

Embrace the tech stream

[errant hawk]

entities is planned to be 2022 LTS+ only. It will likely work with 2019+, but I personally wouldn't use anything prior to 2022 for dots

[gentle gyro]

Did Unity break dots for mobile? I can't seem to get my Dots demo to work on the Quest 2 😦

[errant hawk]

Have you upgraded to 1.0?

[gentle gyro]

Don't know where to find it. But was hopping to avoid a breaking change right now...

[errant hawk]

Then no unity didn't break anything unless you updated your editor or packages

[errant hawk]

1.0 is 2022.2+ right now

[gentle gyro]

Have you been able to do Quest 2 builds with Dots on 2021.3?

[errant hawk]

I don't do VR

[gentle gyro]

Dots .51.1

[errant hawk]

in fact, I don't do any builds at all

or at the very least, incredibly rare

[gentle gyro]

Ok. My Rift S build works fine but can't seem to build for Quest 2...

[errant hawk]

you likely changed something, then

[gentle gyro]

So were do we get 1.0 anyhow?

[errant hawk]

2022.2.0b8+ is where you can add the package. It might be manually by name only right now: com.unity.entities

[misty wedge]

Can I not do this to remove the system from the world?
World.GetExistingSystemManaged<SimulationSystemGroup>().RemoveSystemFromUpdateList(World.GetExistingSystemManaged<FixedStepSimulationSystemGroup>());

Trying to get rid of the physics simulation in the default world

[gentle gyro]

Ah, yes, Thanks!

[sinful cipher]

Ah okay. Only reason I was holding off on 2022 was stability reasons. But all is fine there now? No nasty showstoppers for which I have to wait for a fix from Unity themselves?

[wraith hinge]

no, there's bugs. it's a beta and an experimental package 🙂

[gentle gyro]

Does anyone know where I can find a Hello World Sample that works with ECS 0.51.1 and Unity 2021.3.7 that run on a Quest 2 Build along with a list of Unity Settings for it?

[rustic rain]

all right

I fixed most of my problems just by doing this

    public class BakerTransform : Baker<Transform>
    {
        public override void Bake(Transform authoring)
        {
            var buf = AddBuffer<Child>();
            foreach (Transform transform in authoring)
            {
                buf.Add(new Child { Value = GetEntity(transform) });
            }
        }
    }

👴

[brave field]

🥲 Upgrade to 1.0 exp is damn hard. Still dun have nice auto upgrade yet and I need to manual do all the upgrades

[safe lintel]

yeah its kind of a bear to convert a full, somewhat complex project

[robust scaffold]

Finally got some time to read through the 1.0 changelogs. @viral sonnet

Added ComponentDataFromEntity.GetDataRef and GetDataRefOptional, used to create ComponentDataRef<T> from entity.
Nice. Unity finally is listening to us.

Added new singleton access methods EntityQuery.TryGetSingleton<T>(out T)
Great addition. Makes pulling singleton data inside bursted OnUpdate far easier. Without having to go through get component data array then [0].

Added SystemAPI...
SystemAPI seems rather important. I will need to spend some time figuring out if it changes anything to the struct job code pipeline.

EntityTypeHandle is marked as a read only container because the data is never writable. This means it's no longer required to mark the EntityTypeHandle as [ReadOnly] in jobs.
Finally. That was getting incredibly annoying in various jobs.

Chunks are limited to 128 entities per chunk. This makes enabled components faster since because v128 efficiently culls the entities to process.
Oof. They went forward with this.

Value typed shared components
Nice. I was looking forward to this in 0.50 release. Great to see it landing in 1.0

[misty wedge]

I'm really liking all of the changes

Especially value type shared components. Kept me from bursting a few jobs

[balmy thistle]

What's the problem?

[gentle gyro]

It just crashes... When I try to do a manage debugger script build, it won't compile...

Not sure if I have all the settings right as I haven't found a comprehensive list yet...

[gentle gyro]

Yes, I got it with 'com.unity.rendering.hybrid'. It knows to bring in 1.0

[viral sonnet]

@robust scaffold CDFE is now called ComponentLookup and can return RefRO and RefRW. sadly the pointer is private and we have to use UnsaeUtility.AddressOf. unity dev told me its a no-op though

[brave field]

It seems like IBufferElementData at 1.0 become buggy tat some of the dynamic buffer becomes red

[viral sonnet]

great release for the most part. the only thing that stings is the 128 cap and noone has adresses this yet. 🙂

[gentle gyro]

I recompiled with Wait For Manage Debugger, and it seems to have worked for the first time.
*** * Correction * *** It's still not working. The GameObjects disappear after they convert to Entities...
Have you been able to make a working Build for the Quest 2 with Unity 2021 and ECS 0.51.1?

I have to do some more test to be sure...

[wraith hinge]

i am personally kind of skeptical that the 128 cap is actually commonly a problem. i know @rotund token has a slowdown from that and has extremely tiny archetypes, but he's the only one i've ever heard of who had such tiny archetypes

[robust scaffold]

Yea. It's a tiny blurb but pretty massive change. Hrm.

Swamped with work though. Cant get to coding for another few weeks at least. Pain.

[viral sonnet]

hope you don't have too much authoring comps to rewrite 😄

[brave field]

Btw I would like to get some info from official about dots addressables. From a official reply at forun mention that dots addressables won't support classic game object instantiation and load classic scene. Does it means I need to have both dots addressables and addressable inside project?

[viral sonnet]

one guy on the forum wrote they have 200+ [GenerateAuthoringComponent] ... RIP i guess

[balmy thistle]

One reason to put out the experimental release now, to let people plan for all the changes that will be finalized in the full 1.0 release.

[balmy thistle]

Me personally, no, but I'm not aware of any issues.

[brave field]

On top of that, any update about hybrid component solution?

[robust scaffold]

i got about 6 or 7 which will be a pain to port over. 200, ooooof

[robust scaffold]

That's actually very important. Nothing in the release or changelog mentions hybrid / companion components. Hrm. Not a good sign.

[gentle gyro]

Any chance you know of Anyone who has?

Just want to make sure I'm not chasing a ghost...

[balmy thistle]

I'll ask around

[viral sonnet]

@balmy thistle finally you got your tag. already had a hunch you are unity staff 😄

[gentle gyro]

Awesome, Thank you so much!

[viral sonnet]

it's pretty low on their priority list. understandable as there were much bigger fishes to fry. still a problem, this question comes up every day in some form and nobody can give a good answer, not even what to do other than, write some stuff ^^

the copyTransform system is still around but sealed off so it's unusable. CompanionLink comp is private

[brave field]

Now become even harder to use lol

[misty wedge]

Anyone know if you can access an ISystem's state with reflection?

[viral sonnet]

do you care for the state or for reflection? 🙂

[misty wedge]

I'm gonna guess no but maybe someone else has an idea. The actual code to run the Update, etc function on ISystems is pretty funky

[misty wedge]

Ideally I need to set some variables inside the system

But from what I can tell reflecting SystemState probably won't work

[viral sonnet]

is it generic or can you strongly type it?

[viral sonnet]

what's funky about it? var statChangeSystem = m_World.Unmanaged.GetExistingUnmanagedSystem<StatSystem>(); statChangeSystem.Update(m_Manager.World.Unmanaged);

that's called in my performance test

[misty wedge]

I meant how they call the update method internally

It's not like they have a function to get a pointer or GCHandle to the actual object from what I can tell

[viral sonnet]

oh yeah, definitely 😄 good thing we don't have to deal with that 😄

[misty wedge]

I'm guessing it's possible somehow but I have no idea how

[viral sonnet]

i would first try to make it work without reflection

still not sure what you want to achieve. set some setting is really broad. interface would be fine too for that.

singleton approach also or system handle entity 🙂

[misty wedge]

It's for a dependency injection system

There's definitely ways to do it without but I thought I'd try and see if it works with ISystem

[wraith hinge]

Isn’t there a WorldUnmanaged.UpdateSystem for this

also, the point of isystem is to burst it, for speed. if you want instance stuff so much that you want to reflect, maybe you should use systembase, because reflection is worse than just not bursting it

[misty wedge]

Yeah, but I'm attempting to set a variable that lives inside the ISystem struct

It will only run once at the beginning, so I should be fine 🙂

[wraith hinge]

usually a bad plan, and a much better plan with systembase…

[misty wedge]

Yeah, it already works fine with SystemBase, I'm trying to port the code

If it's not possible I'll probably just drop it

Even if it's kind of a pain since it adds a lot of boilerplate

[wraith hinge]

I’d say if the port requires reflection where there was none, it’s unlikely to be worth it 🙂

[misty wedge]

No, it already currently uses reflection on SystemBase

[errant hawk]

Why are you even needing to assign a field using reflection anyways?

[misty wedge]

For dependency injection

[rustic rain]

pretty sure it's internal

publicise it for direct access

[misty wedge]

What is internal?

[rustic rain]

dependency related fields

[misty wedge]

No, it has nothing to do with EntityQuery or job dependencies

[viral sonnet]

@wraith hinge i was giving up with trying to write a generic ISystem. turned it into a SystemBase. do you see a way to do that?

[wraith hinge]

If you don’t want to burst it, maybe it would work? Because burst doesn’t know how to make separate entry points for each generic instantiation

But if you aren’t bursting then you might as well just systembase

[misty wedge]

Can I get the Type for an ISystem from a SystemHandle or SystemState?

[rotund token]

It's getting hard every morning to wake up and read every comment in here! Too much activity

[misty wedge]

TypeManager.GetSystemType?

[errant hawk]

Wait till unity makes a public post declaring DOTS production ready

[rustic rain]

oof

[half jay]

For what situations is it best to use ISystem? Pure ECS logic also with adding/remove component or only with some calculation stuff without affecting components ?

[wraith hinge]

both. the point is it lets you burst your onupdate/create/destroy/etc

[rustic rain]

Are entities sources posted somewhere online?
No PC around, but I want to learn internal stuff

[safe lintel]

https://github.com/needle-mirror/com.unity.entities

[pastel field]

Damned, enroute to upgrading to 1.0.0 I just read that Havok will only land in pre-release 1.0.
Too much information at once, I missed this "detail".
I hope it won't take months more to come out.

[karmic basin]

Well if it's your last issue to solve, your game is pretty much finished 😅

[rotund token]

updating my libraries has been really easy
updating the samples or demos for my libraries has been a pain because they were basically just quick hacks

i really look forward to seeing what i can redo with SystemAPI though

i have this thing called a DeferredDynamicBuffer
https://gitlab.com/tertle/com.bovinelabs.core/-/blob/master/BovineLabs.Core/Utility/DeferredDynamicBuffer.cs
which is up there with my dirtiest hacks, but I think I can replace this completely now with SystemAPI/singleton

(It turned out if you offset any pointer by 1 byte with an Allocator.Invalid it acted same way as a deferred array)

[misty wedge]

Why is NativeParallelHashMap not unmanaged?

[safe lintel]

er how do you get that singleton system entity?

[misty wedge]

SystemAPI.GetSingleton<Type>(<SystemHandle>) iirc

[viral sonnet]

yeah that's what the ToDeferredArray method does. I never figured out why it works. is it a hack?

[rotund token]

yeah it's patched by job scheduler

[pastel field]

Can't tell, must first resolve package compilation, then, the joyful ones will follow.
But in the end, I don't think I'll have as much modification to do as I originally imagined. Well, I hope so.

[rotund token]

i think it works by simply checking native arrays being unaligned when job is scheduling (pure speculation)

i believe this is why there was this break like end of 0.17 because if you had a byte nativearray and getsubarray it would appear offset

and then patch incorrectly
so they changed it so it only patched on invalid instead of none

[safe lintel]

@misty wedge how does this work in managed systems?

[misty wedge]

I don't think it does, I haven't looked at it at all though

[safe lintel]

yeah api showing all unmanaged but I do see managed singletonsystem entities in the hierarchy

[misty wedge]

It's also SystemAPI.GetComponent<>(<SystemHandle>), my bad

You can get a managed systemhandle iirc

It's part of SystemBase

[rotund token]

yeah it's just literally SystemHandle

[misty wedge]

So I'm guessing it's just SystemAPI.GetComponent<Type>(this.SystemHandle)? 🤷

Does this singleton system differ to the old one? Are the singletons just living inside their own chunk?

[rotund token]

yep

they're just normal entities

[misty wedge]

Is there any read-only performance difference between NativeParallelHashMap and NativeHashMap?

(when reading from it from multiple threads at the same time)

[rotund token]

NativeHashMap is new and optimized for single thread writing

It has a lot less overhead

i expect it would be faster for reading

[misty wedge]

This is for fetching blobassetreferences inside jobs, so It should be fine right?

[rotund token]

reading is fine parallel

NativeHashMap can't write parallel

[misty wedge]

Also are the native parallel collections just not unmanaged so that they can't be put in components due to the safety system?

Or is there another reason

[viral sonnet]

is this code path open to us?

[rotund token]

don't believe so

[rotund token]

I'm seeing no issue with it?

[viral sonnet]

no idea either, the generics have all been rewritten to unmanaged

[rotund token]

yeah that was a bit of effort to update all my extensions

[viral sonnet]

same 😄

[rotund token]

not sure why i hadn't made them unmanaged in first place

[viral sonnet]

new safety system took a bit more though

[rotund token]

interesting, i havent had to touch that at all

[viral sonnet]

you didn't use DisposeSentinel?

[misty wedge]

Eugh, nevermind, it was telling me it was unmanaged because I was missing an assembly reference to Unity.Collections

[rotund token]

only custom containers i made were unmanaged

that's why i made them custom containers 😄

they were basically just containers without the disposesentinel

[misty wedge]

Did they rewrite the dispose sentinel system or why are they all now unmanaged?

[rotund token]

its removed

[viral sonnet]

ah, yeah i wrote the unsafe part and safe nativecontainers

[rotund token]

i believe the allocator now tracks it

(i have not tested or looked at this at all yet though)

[misty wedge]

Ah, I see

Can you nest e.g. NativeList<NativeList<int>> now?

[rotund token]

i havent tested but from what i understand this should still be an error passing in a burst job

[viral sonnet]

there's a strongly typed static now in place static readonly SharedStatic<int> s_staticSafetyId = SharedStatic<int>.GetOrCreate<KeyValueArrayHashMap<TKey, TValue>>();

if (UnsafeUtility.IsNativeContainerType<TKey>() || UnsafeUtility.IsNativeContainerType<TValue>())
  AtomicSafetyHandle.SetNestedContainer(m_Safety, true);

CollectionHelper.SetStaticSafetyId<KeyValueArrayHashMap<TKey, TValue>>(ref m_Safety, ref s_staticSafetyId.Data);
AtomicSafetyHandle.SetBumpSecondaryVersionOnScheduleWrite(m_Safety, true);```

[rotund token]

this for the most part existed pre 1.0

but it was just the prep work i guess

[viral sonnet]

possibly, i haven't seen it in any collections code

[rotund token]

internal static readonly SharedStatic<int> s_staticSafetyId = SharedStatic<int>.GetOrCreate<NativeList<T>>();
NativeList entities 0.50

[viral sonnet]

and as I have no idea about it really it's just copy & pasted code from their 1.0 collections 😄

[rotund token]

oh just to elaborate

the problem is the safety system can't inject safety down an arbitrary depth of pointers

so only the other container would get a safety and all the inner ones would throw errors (usually, this container has been marked as write only it has been historically)

[misty wedge]

That makes sense

And them not being able to be put into components before was just a limitation of the sentinels?

[viral sonnet]

yeah true, NativeList was the first (and only?) container that had the new path in place with the REMOVE_DISPOSE_SENTINEL directive

[rotund token]

nativearray

had it as well

though it was different again

it had just a static int

    [BurstDiscard]
    private static void InitStaticSafetyId(ref AtomicSafetyHandle handle)
    {
      if (NativeArray<T>.s_staticSafetyId == 0)
        NativeArray<T>.s_staticSafetyId = AtomicSafetyHandle.NewStaticSafetyId<NativeArray<T>>();
      AtomicSafetyHandle.SetStaticSafetyId(ref handle, NativeArray<T>.s_staticSafetyId);
    }```

probably because it's inside unityengine and sharedstatic is a burst feature

[viral sonnet]

as you'd have to manually allocate, is this really true?

nvm, i see what you mean

disposing the main can't dispose the elements

[rotund token]

container->container->container->container->somerandomstruct->container->morepointers->container

can you imagine how painful this would be to analyse to figure out what you need to inject the safety handles into

[viral sonnet]

i know way too little about the safety system 🙂

[rotund token]

bit of a black box unfortunately

[viral sonnet]

i think it could be done with losing performance. every container has their own safety and maybe a parent safety. anyway, unity doesn't really seem interested to support this so not much reason to discuss

we can do it in an unsafe way so it's okay

tertle, from what i know how you dislike writing documentations. 😄 i'm leaving my current company and have to document EVERYTHING. it's soul crushingly tedious. make it stop! 😄

[rotund token]

documentation - refer to code

i actually enjoy documenting code

<summary> is a style requirement from my analyser for anything public

alternatively this might also be why i mark a lot of things internal 😄

[viral sonnet]

oh not code documentation. the unfun high level part. explaining what something does, service description, accounts, server/network diagrams

the part that makes you put to sleep

[rotund token]

and you know what happens next right?

someone refactors a chunk in the next few months and the documentation is all irrelevant never to be read

[viral sonnet]

i'm the last dev so i doubt the refactoring part but you are dead on with noone reading it! 😄

[rotund token]

"I could go read Enzi's documentation, but I can't bebothered I'll just rewrite it"

[safe lintel]

ugh so much stuff silently failing to work because the interface doesnt work anymore, kinda wish anything using ICGTE would fail outright

[rotund token]

should at least have had an obsolete tag

if not just outright removal

[safe lintel]

just gonna go and find every instance of it and delete so forces me to fix stuff but between fixing all the other errors, didnt realise how much stuff was just not getting converted so spent way more time than I should have tracking down phantom unbaked things

[viral sonnet]

i used find & replace and changed to IConvert..2

😄

[gusty comet]

so unity added entities

[balmy thistle]

I heard that

[misty wedge]

How does the GetComponent<Type>(SystemHandle) API actually work? How do you set the component? Since SetComponent is missing this overload

Nevermind, it's under SystemAPI

[haughty rampart]

Where are the burst assemblies kept? Need to delete them

[viral sonnet]

If you have tiny archetypes, using entities might be the wrong tool for the job.
What a statement

what's going on here? 104 entities, 102 chunks? unused 12952?

[haughty rampart]

Please, anyone?

[viral sonnet]

Library\BurstCache is my best guess

[haughty rampart]

Prob not

Tried deleting that already

[viral sonnet]

what are you having issues with?

[haughty rampart]

closed my unity project, restarted pc, tried to open it again, says ran out of space while allocating native array, almost crashes my graphics card and almost any other program on my pc

am just gonna create a new one and just reimport everything over and delete the old one

[viral sonnet]

try to delete the library folder first

[haughty rampart]

tried 3 times already

oooooooooooooofffffffffffffffffffffffffff even creating a new project completely crashes almost my whole pc now

[viral sonnet]

oh damn 😦 can you run any game? maybe it's not unity related

out of disk space or smth ^^

[misty wedge]

What happens if you put a managed type in an ISystem?

[haughty rampart]

i mean yeah, i'm almost outta disk, but getting black screens and stuff because of it hmmm.....idk.
am gonna move some stuff to my other drives though

[haughty rampart]

you will get a compile error

[misty wedge]

That's what I thought, but I'm not getting one

[haughty rampart]

have you tried running the game?

[misty wedge]

Nope, but that's hardly a compile error 😅

[haughty rampart]

idk exactly. i just remember you WILL get an error at some point

[misty wedge]

It throws an ArgumentException on running 👍

[haughty rampart]

well it's something i'm gonna cover with the analyzer i'm gonna create. so you will have in VS errors already :)

[misty wedge]

I also managed to inject my types into ISystem but it's probably not a good idea, so I may scrap it

[viral sonnet]

no compile error, just very weird allocation errors. had that at one point in 0.51 when i didn't know we can't use NativeContainers in ISystem

[haughty rampart]

you should be able to do that now btw

[viral sonnet]

yep, now it's possible

[haughty rampart]

wow. seems it ACTUALLY was because there was no more free disk space

even though the project itself was already stored on a different drive that had plenty space than windows

[viral sonnet]

take a look at where windows is storing the paging file

[haughty rampart]

where's that?

[viral sonnet]

in a good os i'd say search for virtual memory. in windows: control panel->system->advanced system settings->advanced->virtual memory section->change

might want to move it to another disk or set a max size

[haughty rampart]

oh, you meant the os paging file.... XD i was thinking unity had something called paging file

ah yes. my paging file is 130gb big

i wondered where that space went.....

[viral sonnet]

lol that's a bit much

[misty wedge]

Any idea what's up with this?
Loading Entity Scene failed because the entity header file couldn't be resolved. This might be caused by a failed import of the entity scene. Please take a look at the SubScene MonoBehaviour that references this scene or at the asset import worker log

[viral sonnet]

clear entities cache

[misty wedge]

Ok so it's just a bug and I didn't break anything

[viral sonnet]

it's possible 😄 but i've had this a bunch of times now. something is still not working right with the baker or incremental baking

very random, can't reproduce it

[misty wedge]

Is there anything I need to watch out for when creating a build? It crashes immediately at bootstrapping

[rotund token]

Mono or il2cpp?

[misty wedge]

il2cpp

[rotund token]

I've already reported an il2cpp issue which they were able to repo and track down due to alignment

i think i won the crash bug race

[misty wedge]

It's also spamming the logs a bunch with this, not sure if it's related: https://hastebin.com/fufujuseki.makefile

[rotund token]

    {
        public BlobAssetReference<MetaData> Value;
        internal bool IsSetup;
    }```
was my issue that causes crashes

mono sees your component as 16 bytes and il2cpp sees it as 9 leading to deserialization issues/corruption
was the explanation

[misty wedge]

What's the issue here, the BlobAssetReference?

Also, do you still need to select Faster (smaller) builds in the il2cpp config? iirc there was an issue with that once

[rotund token]

yes

you do

[rotund token]

pretty much

[misty wedge]

Isn't that kind of a bug? Or what's going on here

[rotund token]

something about il2cpp getting alignment mixed up

[rotund token]

it's totally a bug

[misty wedge]

Ok 😅

I'll try building mono and then with faster (smaller) builds and see what happens, thanks

[rotund token]

but yeah that's the only crash i'm personally aware of atm, though i've only built one of my individual libraries atm

and your stack wasn't exactly the same as mine

so if you have a small repo i'm sure they'd like to know

[viral sonnet]

@wraith hinge I can reproduce this bug now. holding down CTRL+D for duplicate on a gameobject in a subscene with a single baker component to reproduce. it seems every duplication creates a new chunk. to fix the subscene has to be rebuilt.

[misty wedge]

Asset has disappeared while building player to 'globalgamemanagers.assets' - path '', instancedID '-228022' UnityEditor.BuildPipeline:BuildPlayer (UnityEditor.BuildPlayerOptions) wat

someone is stealing my assets

[viral sonnet]

damn those pirates!

[misty wedge]

Also what's this? BuildFailedException: Can't build from the Unity build settings window. Make sure to enable Preferences -> Entities -> Builtin Builds Enabled.

I found the option to enable it, but for some reason calling BuildPipeline.BuildPlayer before didn't trigger this

Might also be why my build crashed 🤷

[haughty rampart]

how tf does burst generate a Object reference not set to an instance of object for me??

XD

[viral sonnet]

has anyone used the unity ObjectPool or DictionaryPool?

[haughty rampart]

you mean the built in object pooling system?

[viral sonnet]

yeah

[haughty rampart]

a bit yeah, sure

[solar spire]

They're a simple and accessible structure, but what's it got to do with #archived-dots ?

[viral sonnet]

pretty much everything on google is a custom script and where i have a problem is that ObjectPool is only for 1 type and DictionaryPool has very unexpected API

[proud jackal]

@viral sonnet You might be able to get better help for that in #archived-code-general , also remember the classic phrase "Don't ask to ask, just ask":
https://dontasktoask.com/

[viral sonnet]

really guys? i've been here for more than a year nearly every single day and you pull that on me for asking 1 question outside of dots to my fellow dots devs? just leave it there and it will sort itself out. i find this kind of rude.

[haughty rampart]

🤷
but a dots question: are nativearrays always aligned?

[rotund token]

Ones you create should be (deferred ones are not until scheduling)

[haughty rampart]

ah ok then. good to know. so i can use load_si128

and what's the diff between .GetUnsafeReadOnlyPointer() and .GetUnsafePointer() ? afaik, if you have a pointer, you can do pretty much anything to it

or does one rather map to like cpp 'reference'

[rotund token]

On what

Native array?

It's still does a safety check to ensure its been setup right

Like if you have a read only array and call non read only version safety will fail

[viral sonnet]

only relevant for safety. apart from the check it does the same thing

[rotund token]

But once you have pointer you're on your own, can do what you want

[haughty rampart]

ah yeah ok. best to use RO in the appropriate places though, even if it's not a RO array. think it's good for code readability

and safety checks get removed anyway when building

[viral sonnet]

(they didn't even know i will feed entities into the ObjectPool and build pooling with the new enabled feature) ... ok j/k ... or am I? 😄

[haughty rampart]

🤔 not....really....a good....use case

[viral sonnet]

oh i am kidding but I'm also thinking about use cases for the enabled feature. previously we needed a structural change for Disabled comp

of course it's kind of useless because we have no dots animation. for the future though, i will be testing the viability because i have a hunch it won't play nice with DidOrderChange and either trigger no update or update the whole chunk

[haughty rampart]

am i missing something or are quite a few intrinsics missing in Unity.Burst.Intrinsics.X86 ?

[rotund token]

What are you looking for?

Speaking of

InterlockedAnd & InterlockedOr

The Unity.Burst.Intrinsics.Common.InterlockedAnd and Unity.Burst.Intrinsics.Common.InterlockedOr are experimental intrinsics that provides atomic and/or operations on int, uint, long, and ulong types.

Because these intrinsics are experimental, you must use the UNITY_BURST_EXPERIMENTAL_ATOMIC_INTRINSICS preprocessor define to get access to them.

These are new in 1.8 right?

[haughty rampart]

if you take a look at this cheat sheet: https://db.in.tum.de/~finis/x86-intrin-cheatsheet-v2.1.pdf
you can see that there are loads of intrinsics available that burst doesn't currently seem to have

[viral sonnet]

i don't see a way to set the enabled/disabled flag in a baker for a comp

[rotund token]

Hmm hadn't really considered that use case but it makes sense

[viral sonnet]

just an IsDead flag 😄

i can flip the logic but it's odd that this is missing

also really weird in that sense: if i have an IsAlive flag I need another comp to make a proper query for it. i can't really query for all IsAlive that are disabled

the answer is YABS - yet another baking system

[errant hawk]

Either 2 components to properly query the entity based off of state, or a single component with flags (need to query all entities, which you may do anyways somehow)

Personally I would have a single component, and in the edge-case you need only dead components, you can add an isDead component

[viral sonnet]

i'd get all sorts of entities if i query for any and exclude IsAlive

[viral sonnet]

no that's a structural change

[errant hawk]

is it possible to NOT a query?

[errant hawk]

It's alive until it's dead

[viral sonnet]

well there is exclude but there is not really a query mode for a comp that is on the archetype but disabled

[viral sonnet]

the baker system can't pick up a prefab that'll be converted with GetEntity

[brave field]

The type 'xxxBufferComponent' must be valid unmanaged type (simple numeric, 'bool', 'char', 'void', enumeration type or struct type with all fields of unmanaged types at any level of nesting) in order to use it as a type argument for 'T' parameter

IBufferElementData not longer can support Hash128?

[late mural]

dealing with nvidia flex, and i really need a way to run a function in a job. At first i was thinking i could store the method in some thing like UnityEvent, but it appears jobs dont allow reference types. Is there any way to run a function in a job? (bonus points if it can be set in the inspector)

[rustic rain]

if job is not burst compiled

you can store delegate pointer

and then unwrap it in job

you'll need MethodInfo of this function

[late mural]

burst compiled would be really nice, cause im doing a for loop with around 70 thousand particles, so performance is very required

[rustic rain]

you can only run native methods in burst

[late mural]

that is really unfortunate

what counts as a native method, im happy to try make one?

[rustic rain]

burst compiled or extern cpp

[late mural]

oh, ill try burst first, and if not then ill do cpp, im dealing with a bunch of cpp pointers anyway, so either solution should be great, thanks a ton!

after i have a native method how do i pass it to the job then?

[rustic rain]

if it's extern cpp

you literally just call it

same with burst

[late mural]

oh and it wont pop up the error about reference types like it usually does?

nope, not working

still gives me an error, it seems it really hates reference types

perhaps there is a value type way of running a function in a job?

[late mural]

hmm, i definitely cant get this working, perhaps an example would help pls?

[misty wedge]

You cannot have reference types in burst jobs. How are you calling your cpp code?

[late mural]

it isnt cpp code yet, ill try that next if the burst code doesnt work, currently im tryna call it with UnityAction's

[misty wedge]

There is no way to use a reference type and have it be burstable. There are ways to sneak delegates to functions inside non-bursted jobs however

[late mural]

hmm that is annoying

im trying to avoid hard coding anything

i really need it be burstable, is there really no value type delegate type?

[misty wedge]

You can create a burst pointer to a function that is also burst compiled, but it has the same requirements (no managed code)

[late mural]

that should work, how would i do that

[misty wedge]

That burst delegate can be passed to a burst compiled method, but I doubt that solves your problem

[late mural]

it might

im willing to try anything

[misty wedge]

https://docs.unity3d.com/Packages/com.unity.burst@1.8/manual/csharp-function-pointers.html

[late mural]

im just trying to mess with particles positions and velocities using c style arrays, so it might work, thanks a ton!

[misty wedge]

Why not convert those arrays to native collections and pass those to a burst compiled job

[late mural]

was always under the impression that converting c style arrays to native arrays was slow, but that was in general c#, perhaps there is an easy method with dots to do that?

[misty wedge]

I'm not sure what you mean by c style array, something like int[]?

[late mural]

int*

pointer arrays

i hate them so much, but i cannot appear to evade them

[misty wedge]

Alright, then you can either memcpy the data or possibly just set the internal collection pointer (although I've never tried that)

[late mural]

dont know what either of those mean, but ill research them, thanks a ton!

[late mural]

hmm it appears this only works with static methods, which i might be able to use, but ill need to figure out a way to convert vector 3 to vector 4 without overwriting W to 0, and without using new so it stays static, a fascinating challenge

[misty wedge]

The reason it only works with static methods is otherwise it would be binding the managed this, which isn't allowed in a burst function

[late mural]

ok, i think i should be able to work with that, thanks a ton!

[misty wedge]

Regarding the c style arrays, something like this should work, but there may be faster ways to do it, I'm no memory guru like some others here:

int[] arr = { 1, 2, 3 };
NativeArray<int> native = new(arr.Length, Allocator.Temp);

fixed (int* ptr = arr)
{
    void* nativePtr = native.GetUnsafePtr()
    UnsafeUtility.MemCpy(nativePtr, ptr, sizeof(int) * arr.Length);
}

ignore the fixed part, you already have an unmanaged pointer

[late mural]

ooh that might work, ill try that in the morning, thanks for all the help!

[coarse turtle]

You can also use ConvertExisitingDataToNativeArray to alias a NativeArray to a T* ptr.

[safe lintel]

is there a way to view all the bugs you submit these days? their new system doesnt have that overview like fogbugz did

[misty wedge]

Where is this function?

[rustic rain]

Is there any way to have my code run outside of systems?

[proud jackal]

Depends what you wanna do, but yes :3

[rustic rain]

I want to have injection into default World implementation either before systems are created

or before OnCreate is called

but I'd guess

the only way - create world manually

[misty wedge]

What are you trying to inject? just have another function that runs before OnCreate?

[rustic rain]

kind of

but I need it to be world specific

afraid I'm gonna have to use on demand approach

when code runs as soon as it's called

which doesn't work too well with burst

[misty wedge]

Btw if anyone has any ideas what is going on here I'd appreciate it, I can't find anything online and it's completely preventing me from creating a build:
Asset has disappeared while building player to 'globalgamemanagers.assets' - path '', instancedID '-477562' UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

[haughty rampart]

had that happen once too. i just ignored it and it was fine

[misty wedge]

It cancels the build...

Unless I missed something else that was interfering, but I'll double check

[coarse turtle]

https://docs.unity3d.com/ScriptReference/Unity.Collections.LowLevel.Unsafe.NativeArrayUnsafeUtility.ConvertExistingDataToNativeArray.html

[misty wedge]

I can't see any other errors besides this one, so I guess I'm screwed

[coarse turtle]

It doesn't set the safety handle - so you'll either need to set it yourself or disable safety checks if you put it in a job

[misty wedge]

this is the entire build logs I get: https://hastebin.com/woribugice.makefile

message I posted is the only "real" error I see

[haughty rampart]

maybe restart unity and try again?

[misty wedge]

Already tried everything

reimport

[haughty rampart]

hm.

[misty wedge]

Maybe I'll try pulling new completely, but I doubt that changes anything

very annoying

It worked yesterday, but I can't think of anything I changed

[wraith hinge]

have you tried deleting the build dir

i wonder if it's the incremental build pipe getting confused

build and/or library and/or git clean -xdff

(i'm not aware of any active bugs in that area, but that's also a crazy error, so...)

[misty wedge]

I've deleted everything in the build folder and deleted the library folder

I'm reverting a few commits back and seeing if I can build there, otherwise the only thing I can think of is pulling the project fresh and seeing if that works, then I'm out of ideas 🤷

[wraith hinge]

There are some pieces of global state outside the project that can get corrupted in rare cases

Notably the global package cache

[timber ivy]

I was trying to dig through the source to find it but how are entity id's created and managed?

[rustic rain]

what
var cachedCameras = Object.FindObjectsOfType<Camera>();
This stopped working in unity 2022

hmmm

any idea how I can pass game object from scene into World?

no conversion

[half jay]

through blob assets?

[rustic rain]

that's not what they are for

[safe lintel]

@rustic rain that works for me, I literally just made a system that does var sceneCamera = Object.FindObjectOfType(typeof(Camera)) as Camera; last night to get the camera

[rustic rain]

🤔

nope

that gave me empty array too

hmm

[safe lintel]

sure there are cameras in the scene?

[rustic rain]

yeah

I'll try

using FindObjectOfType

isntead of Objects

using container with references

welp

it works

looks like bug

aaand now it doesn't work 🤔

[mild ledge]

Im hella confused. The new burst occlussion is part of the dots.graphics aka renamed hybrid renderer. But cant I just use that to render my graphics and keep the game with monos and gameObjects ?

But then I dont get subscenes and level streaming or do I ?

[safe lintel]

@mild ledge i think it is rolling out to gameobjects after

GameObject support is planned for the future, which requires it to be decoupled from the Entities Graphics package.

[mild ledge]

I know that, but I really want to start a project that relies on dynamic occlusion and dont feel comfy doing it in pure dots

[safe lintel]

https://forum.unity.com/threads/burst-occlussion-culling.1342346/#post-8477345

well you will have to wait then

[mild ledge]

I started that thread🤣

[safe lintel]

sucks, I think everyone here is probably waiting on some major feature or two for their own uses

[mild ledge]

I remember using just the hybrid renderer to "replace" mesh renderers maybe it will work the same will have to give dots 1.0 a spin on mondat

[misty wedge]

I'd be content if I could build a player...

[safe lintel]

@misty wedge dont be so sure, I built a player that crashes immediately on load 😭

[misty wedge]

That just happened to me, it crashed before it even got to the splash screen

[rustic rain]

Guys any other way to inject data into world?
This is just absurd
var cameras = Object.FindObjectOfType<WorldReferences>(); returns null, while I have this GO

[misty wedge]

Where are you calling this?

[rustic rain]

in OnCreate

[misty wedge]

Call it later

[rustic rain]

🤔

[misty wedge]

iirc they changed something in when OnCreate runs in relation to normal mono world

I had some stuff failing too that worked before, which ran in Awake

[rustic rain]

bruh

[safe lintel]

well I made it to the splashscreen at least

tried both dots platform asset build and builtin build

[rustic rain]

I wish they have a special callback

PostCreate

or smth

before world actually runs

[misty wedge]

OnStartRunning?

[rustic rain]

no

that runs every single time required query runs

[misty wedge]

You can add it relatively simply

Just call a function on each system that e.g. implements an interface after you created the world

[rustic rain]

I know, but...

[misty wedge]

That will cause all OnCreate to run, then your function

[rustic rain]

feels weird Unity won't do it themselves

[misty wedge]

I'm not sure many people need it 🤷 maybe they'll add something

Also couldn't you just put your Component reference inside a managed IComponent and then query that in a system?

[rustic rain]

the problem is that

literally everything is tied to OnCreate

so I just don't have Component

[misty wedge]

The component reference would be baked

[rustic rain]

by the time I need it

[misty wedge]

(if that even works, I haven't tried it)

[rustic rain]

nah, it doesn't

all references die

[misty wedge]

😦

[rustic rain]

in subscene

[misty wedge]

Then just fetch it in OnUpdate

[rustic rain]

🥲

[safe lintel]

are you trying to keep a reference inside a subscene of an object that is outside the subscene?

[rustic rain]

no

I literally have 2 cameras in a scene

normal scene

and I can't grab them inside World

[muted star]

Hi everyone, is it possible to configure a system group to not update at all, unless manually updated?
I would like to manually update a system group at certain points in time, without updating the world.

I guess one possibility would be to set RateManager.Timestep = 99999f; but I think the system group would still be updated on the first update of the world.
Also, I would prefer not using a rate manager at all, because it makes debugging more difficult.
Rate managers don't work properly when pausing and resuming the game in the Editor Play Mode. (Has this been fixed it 1.0?)

[safe lintel]

to echo what schnozzlecat said, I do run my find camera thing inside of OnUpdate and disable the system after that bit of logic runs

if it doesnt find anything return until it does

[rustic rain]

🥲

[misty wedge]

Can't you just disable the system group?

[rustic rain]

I consider disabling default world creation

for the sake of normal world creation workflow

[muted star]

Neat! I'll give this a try 🙂

[viral sonnet]

morning everyone. does anyone run a bakingsystem on prefabs that are linked in a subscene? (previously IDeclarePrefabReference) the baking system doesn't pick them up, not sure how to proceed as I'm under the impression that this should work.

[wraith hinge]

did you do the thing where you make sure the query includes prefabs

that always gets me

[viral sonnet]

could be it! 😄

[rustic rain]

Anyone else knows how Default world creation works?

[viral sonnet]

that was it! thanks for the quick answer. i need to be more aware of this

[safe lintel]

@wraith hinge can one make new/additional entities inside of a baking system or is that only to be done inside of a baker?

[rustic rain]

I'd guess that's what I need UNITY_DISABLE_AUTOMATIC_SYSTEM_BOOTSTRAP_RUNTIME_WORLD

[wraith hinge]

afaik baking systems are anarchy

so just go nuts

[safe lintel]

well thats kind of the thing where I would get an error about too many entities sharing a guid if creating them through a baking system via EntityManager.Instantiate(prefab)

[wraith hinge]

errr i'm not aware of that error but i'm also not a baking pro

[safe lintel]

alright thanks, ill try to make a simple repro to submit

[viral sonnet]

hm, i want to disable an IEnableComponent in the baking system. this picks up the entities but it's still not turned off when i inspect in the hierarchy ```public void OnUpdate(ref SystemState state)
{
Debug.Log($"Running IsDeadBakerSystem");
var ecb = new EntityCommandBuffer(Allocator.Temp);

        foreach (var (_, entity) in SystemAPI.Query<IsDead>().WithAll<Prefab>().WithEntityAccess())  
        {
            Debug.Log($"turning off IsDead for {entity}");
            ecb.SetComponentEnabled<IsDead>(entity, false);
        }
        
        ecb.Playback(state.EntityManager);
    }```

[wraith hinge]

i have had some issues with the hierarchy making me lose my mind for various reasons and i'm not sure they're all fixed yet

i would double check with a query

the hierarchy picks up prefabs, iirc? and didn't always have the behavior i want wrt enabledness

[viral sonnet]

on that note, it would be great if we could just set the state of IEnableComponent in the baker itself

[safe lintel]

unity bug reporter is so slow to upload

ok IN-18378 simple repro that entities created inside of baking systems arent created

or they are but it complains theres no scenesection so they dont survive serialization or whatever 🙂

[wraith hinge]

oh scenesection you say

that makes me think i could be wrong that it's supported (but obviously that would not be the right error message, so it's still a bug)

[safe lintel]

well if I use CreateEntity I get that warning, in my main project if I use Instantiate(prefab) i got another warning, just testing Instantiate(prefab) in this small repro fails silently

[wraith hinge]

well, at minimum, we need an error message, and for it to tell you that you can't do what you're doing, if in fact you can't 🙂

[safe lintel]

that would be appreciated 🙂

[misty wedge]

After deleting everything and reimporting 50 times I can now build again for some reason even though it failed with same error in some parts, only issue is that the build crashes before even hitting the splash screen

https://hastebin.com/eqagusulay.yaml fastest crash in the west

[wraith hinge]

that is a rather less helpful stacktrace than usual, but there are some known crashes in il2cpp builds right now that we're working on fixing

so i would think it was that

[safe lintel]

hey that looks just like my crash 🥲

[misty wedge]

copy cat

my build crashed first!

[safe lintel]

https://hastebin.com/zinowepawa.yaml 😅

[misty wedge]

meaning a mono build should work?

[safe lintel]

well I reported my crash last night 🙂

[wraith hinge]

i believe so? at least i thought all the known crashes so far are il2cpp-specific

[safe lintel]

(crash repro bug)IN-18341 if interested

[rustic rain]

Is there a way to ensure BakingSystem runs after another?

It feels like UpdateAfter just doesn't work on them

[misty wedge]

Great, I do nothing except switch to mono, and then I get this again
Asset has disappeared while building player to 'globalgamemanagers.assets' - path '', instancedID '-479478' UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

zzz

I think this is somehow related to addressables, but I'm not 100% sure

[wraith hinge]

this seems like a separate bug, which may or may not be dots related, yeah

addressables definitely talk to that code pretty deeply

[misty wedge]

I think I'll just give up creating a build and wait until 2022.2 releases

[wraith hinge]

very reasonable idea 🙂

[misty wedge]

The upgrade to 2022.2 also bumped my addressables version from 1.19.19 to 1.20.5, so maybe I'll try downgrading...

[wraith hinge]

i'm skeptical

[safe lintel]

oh holy moly mono build works for me

[misty wedge]

why do you lie

[rustic rain]

ArgumentException: A component with type:Unity.Scenes.SubScene has not been added to the entity. Entities Journaling may be able to help determine more information. Please enable Entities Journaling for a more helpful error message.
Anyone else having this?

ok, those appear because I create my world after Awake

hmm

any idea how I can reregister all subscenes?

[rustic rain]

So, hierarchy window causes this. Hmm 🤔

ArgumentException: A component with type:Unity.Scenes.SubScene has not been added to the entity. Entities Journaling may be able to help determine more information. Please enable Entities Journaling for a more helpful error message.

I wonder if that's an internal bug or I am doing smth wrong

[viral sonnet]

so that's why I can't disable an IEnableComponent Behavior at Playback: Will throw an error if this entity is destroyed before playback, if this entity is still deferred, if the entity has the <see cref="Prefab"/> tag, or if the entity doesn't have the component type. doesn't work on Prefabs.

the error is never thrown btw

[viral sonnet]

very peculiar design to expect every comp is enabled. i could work around it with a runtime system but that doesn't feel right and it's a bit hard to control without a structural change. the question now, is this here to stay or was this simply overlooked?

[hollow sorrel]

i hear 1.0 experimental is out

what's the verdict

[viral sonnet]

i don't think it's worth it yet

[rotund token]

Lies

[rustic rain]

Not worth it

everything is broken

[viral sonnet]

unless you are really into into and want to alpha test

[rotund token]

Is it? Or is that your obscure way of building everything issue 😄

[hollow sorrel]

not worth it compared to not using dots, or not worth it to upgrade from 0.51 (or whatever the previous was)?

[rotund token]

ISystem is mint

[viral sonnet]

to upgrade. dots and entities is phenomenal

[hollow sorrel]

damn

[viral sonnet]

true, however we can't pick and choose 🙂

[hollow sorrel]

my worry is the more things they change the more terrible it'll be to update
so would think it's better to update now and have to update less later than do a huge update later

[rustic rain]

nah, I got some internal errors

no idea how to deal with them

[rotund token]

Anything outside of hierarchy/ui?

[rustic rain]

it's hierarchy ui xD

[rotund token]

I'm at 11/14 libraries running now without many issues

[rustic rain]

Can't debug my entities without it

[rotund token]

Except random ui errors that don't really cause any problem second time I select something

First select fail, second+ select fixes itself

[hollow sorrel]

i'm still 'stuck' (haven't touched it in a while) updating to 0.51 because unmanaged systems broke my custom world init

[rotund token]

I found 0.51 upgrade to be quicker but more broken

[hollow sorrel]

did they add custom world support to the DOTS windows yet? like is it possible to see what systems are running in manually ticked world

[rotund token]

Haven't tested

But if you don't add it to playerloop good chance it won't work

[hollow sorrel]

:(

[rotund token]

Again untested, but I don't think you should do it that way anyway

Just add it to player loop and do it how netcode does to determine if it should tick

With custom system groups etc

[hollow sorrel]

not sure how that could work when trying to do rollback with a separate world for simulation and rendering

[rotund token]

Hmm

Not sure for that case

I do not my roll back in same world

[hollow sorrel]

what were the broken things you ran into?

[rotund token]

oh in 0.51

(might have been 0.50 cant remember)

i had a thread up with like 10 major gotchas and issues within a few hours

https://forum.unity.com/threads/compilation-of-issues-with-0-50.1253973/

most of these were fixed so you won't have issues

[hollow sorrel]

ahh i see

thanks for writing these up

[rotund token]

i haven't really had to write up a 1.0 version which is nice

might write up a, useful stuff you might not realize you can do in 1.0 instead

[viral sonnet]

i think it was 0.50. 0.51 has been really stable. eh nvm you have it in the forum title 😄

when most errors are based on codegen i don't think it's that bad.

i have new codegen errors in 1.0 🙂

biggest problem is when the issues are a bit more fundamental. and i would not suggest anyone to upgrade mostly because of bakers. those things will be sorted out, i'm very sure of it. still takes a bit of time.

[rotund token]

you and your generics

[viral sonnet]

i've solved the generics 🙂

i'm having a lot of small problems I can work around, so it's okay. but I'm not handwaving others issues and issues issues (lol) because it was clearly working in 0.51 in a better way.

the baker has some restrictions and needs likely 2-3 patches to be called great

[rotund token]

a list of things for me to avoid would be nice 😄

[viral sonnet]

i'll try to write a concise list of things in the forum

sometimes we have workarounds, sometimes we dont

[rustic rain]

hmmm

Anyone played with custom world creation?

[gusty comet]

wdym custom

[rustic rain]

RegisterUnloadOrPlayModeChangeShutdown();
I noticed this method in DefaultWorldInitialization

[gusty comet]

you mean like

procedural

?

[rustic rain]

no, I just want to have my own world creation pipeline

to have precise control over when systems are created

when my own extensions are created

and etc

[gusty comet]

ok

[viral sonnet]

long time i've done this but it was just a matter of new World() and then using the EntityManager from it

[rustic rain]

yeah, seems so

I want to use custom bootstrap

because

it seems like UI is broken

if I do it otherwise

[rotund token]

Well it's basically designed for this purpose

[rustic rain]

any tip what is general way of doing it?

new World()
do whatever I want
Get All systems from TypeManager
Create them in any order I want

That's it?

Do I have to register world anyhow?

for playerloop

[rotund token]

I think just return it

But hmm you usually call the method that adds the default systems to the loop

(is the only thing that actually has to be added)

Just look how it's setup by default

[rustic rain]

I am not sure what is actual default implementation

[rotund token]

Default world Initialization

It will try create via custom boot strap

If not, set it up instead itself

[rustic rain]

well

judging by this piece of code

if I return my world

Init will do early return before all loop registration

[rotund token]

Ah well then yeah you need to set it

[rustic rain]

also I don't what is this event

which is invoked

[rotund token]

Yeah call those 2 methods

[rustic rain]

in my IDE it's unused

[rotund token]

Ignore it 😄 or call it if you really want

[viral sonnet]

SystemAPI.Query is mainthread only, yet we can't use MBs in the query.

can't query my Animator QQ

[uncut rover]

Do class component work ? Or can aspect handle that ?

[proud jackal]

MB?

[viral sonnet]

MonoBehaviour

[proud jackal]

Gotcha, yeah, no, but IJobEntity does support it :3

As long as you schedule with .Run ofcourse

[misty wedge]

After managing to build a mono build, my game crashes during the initialization of the Unity.Physics.Systems.BroadphaseSystem

[viral sonnet]

will MBs eventually be supported in SystemAPI.Query?

[misty wedge]

It specifically crashes on burst generated code

EntityQueryImpl.GetSingletonChunk

Is it possible to disable burst for a standalone build?

[proud jackal]

Maybe, it feels like an oversight more than anything :3 (tho there is an argument to be made against it, as we might wanna support Query in jobs, tho chances are we just make it a compile error to use managed comps in that case)

[misty wedge]

This line crashes my build for some reason:

[rustic rain]

huh, seems like default system creation has changed a lot

[devout prairie]

Was just wondering if removing runtime conversion will have an impact on potential modding.. just speaking loosely as i haven't looked into whether it's even possible

I always wondered if it would be possible to load in mod dll's ( using a mod tool such as Bepinex ) that could then do runtime conversion of external assets

Something like:
You release a game
Someone writes a mod dll that loads in some fbx models and injects them into the game

[wraith hinge]

Full stacktrace? Yes possible to disable burst in build; go to project settings burst AOT settings

I imagine some path is unsafe but not getting exercised in the editor, and then it blows up in a build because there’s no safety in builds right now

[misty wedge]

https://hastebin.com/otubovolaw.yaml

This is in a debug build if that makes a difference, I wanted to step through and see where it crashed

This was the last managed line I could execute, which matches the stack trace:

[wraith hinge]

I would think it means something you are doing in one of your own oncreate’s is funky in some way

[misty wedge]

Why would it crash in the physics on create then?

I didn't change any oncreate from entities 0.51 iirc, which worked fine in builds

Just updating to new APIs, etc

I'll look at them though and see if I find anything strange

Everything also works fine in the editor, it's just the build that is crashing

[rotund token]

You should load the crash dump

And find exactly where it crashes

[viral sonnet]

good old null ptr

[misty wedge]

it wasn't me I swear officer

This is the call stack:

[viral sonnet]

likely this one: SystemAPI.GetSingletonRW<SimulationSingleton>();

[misty wedge]

Yeah, I posted it up a bit higher

[viral sonnet]

no idea really but it means it doesn't exist, yet the query says it does. it's an IEnableComponent btw

[misty wedge]

That seems like a bug

[viral sonnet]

oh nvm, the singleton isn't.

is this just with il2cpp?

[misty wedge]

mono

il2cpp crashes for me before even getting to the splash screen

[viral sonnet]

ive' seen this here but what is this? BuildFailedException: Can't build from the Unity build settings window. Make sure to enable Preferences -> Entities -> Builtin Builds Enabled.

[misty wedge]

You just need to set a check mark in the preferences

[viral sonnet]

yeah but why?

[misty wedge]

Or do you mean what it does?

I have no idea, I'm guessing it does magic to make it possible to create a dots build

[viral sonnet]

this is the weirdest checkbox i've ever ticked

good thing it has no captcha behind it. i might have failed it

[misty wedge]

Are you sure you want to do what the button does that you just clicked?

I'm wondering why it isn't enabled by default if you have Unity.Entities installed

[viral sonnet]

please read the instruction, click this other button so you can click the button you wanted to click

yeah i dunno 😄

do we have to add subscenes in the build settings? at least they are auto added when i use add open scenes

[misty wedge]

I want the old build config back 😢

[viral sonnet]

yeah 😦

ok i get a crash too. different errors though

first one is ArgumentException: Unity.Entities.PostLoadCommandBuffer is a class based IComponentData. Class based IComponentData must implement a default constructor. PostLoadCommandBuffer has a default constructor. just checked

  at System.RuntimeType.CreateInstanceMono (System.Boolean nonPublic, System.Boolean wrapExceptions) [0x00076] in <bcca6c60cac14795a89f3b6ba8f7daa8>:0 ```

[misty wedge]

I don't think that error causes a crash

I get it too

[viral sonnet]

yeah, still an exception which breaks code execution. can't be good

[misty wedge]

Probably

I get like 10 of those

But it crashes on the broad phase oncreate

[viral sonnet]

look what we have here 0x00007FFE28EE1B68 (lib_burst_generated) [I:\DungeonGank2022\Library\PackageCache\com.unity.entities@1.0.0-exp.8\Unity.Entities\Iterators\EntityQuery.cs:1410] Unity.Entities.EntityQueryImpl.3322::Unity.Entities.EntityQueryImpl.GetSingletonChunk 0x00007FFE28F4711E (lib_burst_generated) [I:\DungeonGank2022\Library\PackageCache\com.unity.physics@1.0.0-exp.8\Unity.Physics\ECS\Base\Systems\UnityPhysicsSimulationSystems.cs:161] Unity.Physics.Systems.BroadphaseSystem::Unity.Physics.Systems.BroadphaseSystem.OnCreate

same as yours

i'm getting a bit annoyed that on every entities release we have another build crash in physics. are they testing builds? it's such an universal error, not something weird we are doing

this time we cant fix it with a dropdown probably

[misty wedge]

Nice, guess I didn't break anything after all \o/

[devout prairie]

My main concern here is what is DungeonGank 😂

[viral sonnet]

all my projects are XXXGank! lol who names things properly

[devout prairie]

Haha love that..

So physics is crashing builds.. that's annoying 😐

[misty wedge]

XXXGank sounds like it should be rated 18...

[devout prairie]

I've been holding back on dropping what will probably be days on doing a conversion

( to 1.0 i mean )

[viral sonnet]

wonder if anyone is able to make a build with physics

stay on 0.51 if you can unless you don't value your productivity 😄

[devout prairie]

looks like they've updated all the samples including physics, i wonder if it's worth trying to build one of those

[devout prairie]

haha sadly i value every hour

[misty wedge]

Hey I was very productive today, I spent the day deleting library and reimporting to create a few builds that crashed

[devout prairie]

haha, tbf sometimes a lot of days feel like that anyway, two steps forward one step back

[misty wedge]

wow look at this guy, actually moving forwards...

[viral sonnet]

the days before 1.0 i learned UIToolkit so it's just a fitting continuation of the level of productivity

[devout prairie]

we're all the guinea pigs

[viral sonnet]

i've so many baking errors. i'm very close of just dropping 1.0

i just wondered why this one monster is just standing at 0/0/0 - i wonder why my player doesn't move.

oh comps don't exist. but they do on the prefab. clear entities cache. works again

over and over again

i have cleared the cache at least 30 times today

i'm pretty sure the GameObjectChangeTracker screws things up but that's just a hunch

[rustic rain]

They should just bring old conversion back

It was so much more versatile

[viral sonnet]

at least make a smooth path to bakers

it's so annoying, my code base is screwed

[rustic rain]

I don't get what's the point of making conversion so strict

Especially performance wisr

Considering it's fully offline

[viral sonnet]

chewed of more than they can eat or what's the saying?

[rustic rain]

I swear, I want to implement back conversion system

[viral sonnet]

baking is one thing but incremental baking. oh boy

[rustic rain]

Which would allow iteration over gos

[viral sonnet]

make a code change: Loading Entity Scene failed because the entity header file couldn't be resolved.

this time not even clearing entity cache can save me.

[rustic rain]

Yeah, worst part - you almost never know what's wrong

Have to guess

[viral sonnet]

yeah it only tells me the subscene which threw the error. i just made a code change to a system. nothing to do with baking so i know this would work

restarted unity. now it's working again

well, my system based pooling system works. at least that counts for something

kinda cool, the hybrid system i'm using isn't just relying on instantiate anymore and can draw from a pool of released presentation gos. only downside is that i need an instanceID mb comp to keep track from which orefab the instance is coming from

afaik there's no way to determine from which pfefab a go was instantiated

[misty wedge]

Baking has been working fine for me but I have like 5 entities I'm baking so maybe that's why

Except the random times I get this Loading Entity Scene failed because the entity header file couldn't be resolved.

[viral sonnet]

how often did you get this error in 0.51?

[misty wedge]

Never I think

I got it in 0.17 iirc, it was a bug that had something to do with UIToolkit if I remember correctly

[viral sonnet]

I got it like 2 times this whole year. now constantly

[misty wedge]

I'm sure it'll be fixed, 1.0.0 was just released

[viral sonnet]

sure it will 🙂

[coarse turtle]

So something that I'm curious about is - back in 0.51 and prior I could use GetPrimaryEntity(UnityEngine.Object) so I could declare Asset dependencies in a GOConversionSystem. What's the equivalent of that in 1.0, since it looks likeGetEntity takes in a UnityEngine.Component or GameObject 🤔

[viral sonnet]

just GetEntity

[misty wedge]

Component and GameObject inherit Object

[viral sonnet]

call it with your GO, done

[coarse turtle]

ah sucks, the Object i wanted to grab was a Material haha

[misty wedge]

Oh, nevermind, I misunderstood

[coarse turtle]

so it doesn't fall under UnityEngine.Component or a GO

[viral sonnet]

oh, and that worked in 0.51?

[coarse turtle]

Yea

// 0.51 in an IConvertGameObjectToEntity
var materialEntity = conversionSystem.GetPrimaryEntity(material);
dstManager.AddComponentData<LinkedMaterialEntity>(entity, materialEntity);

[viral sonnet]

looks like another regression

[coarse turtle]

I'll probably rethink this so I'll just circle back and finish converting the rest of my project lol

[viral sonnet]

you should be able to provide the go of the material, right? or did you just reference the mat?

[coarse turtle]

i just referenced the material

i haven't touched my rendering side in a while and since the BatchRendererGroup is available in 2022 - I'll likely want to rethink how I'm doing rendering again lol

[viral sonnet]

i'll take a look what the HR does (we need another abbrevation for Entities.Graphics btw 😄 )

[coarse turtle]

I'm pretty sure I could use AddComponentObject, but since I had originally linked entities together - I probably just need to refactor my system to use that instead ¯_(ツ)_/¯

[viral sonnet]

so first thing, you want to have a single entity for a material right?

[misty wedge]

Is there no way to add a scene object to a component from a baker?

Since the managed objects don't seem to be able to live in the subscene

[coarse turtle]

yea

[viral sonnet]

looks like you need to make a MB comp, reference the material there and implement a Baker for this MB comp

then you can reference the base go in others

bit annoying though, there might be a better way

[errant hawk]

Any of your managed components missing a parameter-less constructor? For whatever reason, issues with the baking system completely screws over the ability to load subscenes sometimes

[viral sonnet]

i'll check if any constructors are missing

i've found 2. let's see if it's better. how did you find this out? i'd never relate these 2 things.

[errant hawk]

It was an issue for me, I reported it to a unity admin (as a bug report) with as much detailed info as I could

[errant hawk]

I think that subscenes have some heavy relations to the baking system

[viral sonnet]

interestingly i found a bunch of these errors in my build log. (#archived-dots message) they are unity comps and have a constructor so i dunno what's happening here

[errant hawk]

Needs to be an empty constructor

zero parameters

[viral sonnet]

looks fine to me

[errant hawk]

Try removing the RefCount assignment. maybe it wants absolutely bone-dry constructor

[viral sonnet]

can't that's a unity comp 🙂

[errant hawk]

you mean that was decompiled?

or from the package

[viral sonnet]

entities package

[errant hawk]

hmm...

[viral sonnet]

there's also an error for EndSimulationEntityCommandBufferSystem.

[gusty comet]

what's the advantage of having entities instead of scripted objects

[viral sonnet]

and my hunch is that these errors break the loading and get physics to crash

[errant hawk]

you're using v1.0 right, not 2.0 transforms?

[viral sonnet]

v1 yeah

schnoozle has the same error. are you using physics?

[errant hawk]

Have you tried readding all the packages?

[gusty comet]

do they have any special properties

[rotund token]

Where is your actual crash

Have you checked your dmp file?

[errant hawk]

I have physics added, no issues so far other than crashed from the above issue I mentioned with constructors

[viral sonnet]

#archived-dots message

[rotund token]

That's your log

[viral sonnet]

so your build works with physics?

[rotund token]

Not your dmp file

Load up the generated dmp file in VS it will show you exactly what line you crashed on

[errant hawk]

@viral sonnet what's your editor version

[viral sonnet]

2022.2.0b8

[viral sonnet]

on it but what should i do with it? 🙂

[rotund token]

Just open with vs

Hit run top right

Then link your pdbs if it doesn't auto link

And it'll give you the memory state at the time of crash

Full stack you can step through

[viral sonnet]

it's the same thing that schnoozle posted

[rotund token]

Can you step back a few

Where's this being called from

It seems the singleton isn't being setup?

[viral sonnet]

sorry i don't know how to step back. this is the only step available

[rotund token]

You don't have a stack?

Should see a call stack mid bottom by default

[viral sonnet]

but this is the crashline: SystemAPI.GetSingletonRW<SimulationSingleton>(); from BroadphaseSystem

[rotund token]

Hmm on tram heading home so can't look myself

But where is that meant to be setup

Don't worry, I'll inspect this when I get home

Feel like I must have made at least 1 of my libraries with physics

So not sure why it didn't have issue (though they probably had no colliders setup in build)

[viral sonnet]

found the call stack. never needed this when working with dmp files but this is cool 😄

[rotund token]

It's easier to debug a crash in a build

[viral sonnet]

anyway, same line i posted

[rotund token]

Than an exception in burst in editor

In editor all you get is, please turn off burst
