[muted field]

both bezier and line segments are structs and only hold basic value types

so i dunno why its saying they are managed unless i misunderstand it

[rotund token]

what line is your error on?

it would imply you're doing someting like
object a = (object)1;

[remote crater]

HDRP isn't working out for me. I can't use an image to make a custom skybox at runtime like other rendering packages, and its 33% less Frames per second. What other rendering package does DOTS support so I can migrate?

[rotund token]

dots supports both urp/hdrp

[remote crater]

ty

[muted field]

it doesn't take me to a line but it says Boxing a valuetype Geometry.Bezier to a managed object is not supported so i presume the first case statement

[rotund token]

can you show me deform job

[muted field]

i dunno why its considered managed - its a struct with only basic value types in it no ref values

sure

    [BurstCompile]
    private struct DeformJob<T> : IJobParallelFor where T : unmanaged, ISpline
    {
        NativeArray<float3> _vertices;
        NativeArray<float3> _original;
        T _s;
        float _tMin;
        float _tMax;
        public DeformJob(in T spline, in float tMin, in float tMax, in NativeArray<float3> vertices, in NativeArray<float3> original)
        {
            _original = original;
            _vertices = vertices;
            _s = spline;
            _tMin = math.clamp(math.min(tMin, tMax), 0, 1);
            _tMax = math.clamp(math.max(tMin, tMax), 0, 1);
        }
        [BurstCompile]
        public void Execute(int i)
        {
            Set(_s, _tMin, _tMax, _original[i], out float3 result);
            _vertices[i] = result;
        }
    }

[rotund token]

that looks alll fine

nothing is casting to ISpline is it?

[muted field]

oh well the Set function checks if the spline is a certain type

is that why?

it has a line which does this on the spline input : (s is Bezier b && b.IsClockwise ? -1 : 1) * math.sign(input.x);

is that whats boxing to a managed type ?

ok it is that issue i just commented it out and the error went away

ill just pass in a bool instead

[rotund token]

hmm

i thougth is avoided boxing

but yeah not sure is Type t

[muted field]

T is an interface or at least restricted to one

but its declared unmanaged every step of the way aswell

[rustic rain]

Why not let baking do it's job?
Just create prefab that holds this material and then access it however you want to get material index

You are not supposed to do any changes to RenderMeshArray

Neither it will help you do what you want

[drowsy pagoda]

I actually just got it to work. I read the Graphics docs and got it to work. The issue is when setting the renderMeshArray.Materials you can't just raw assign it. You have to use RenderMeshArray.CombineRenderMeshArrays, then it works.

It's pretty cool what they did, they allow you to switch materials and mesh on the fly, even from parallel burst jobs!

[rustic rain]

But sir, it's just not smth you should do I think, since there's much more stuff around it that connects it to BRG

If you just keep prefab reference in subscene it'll register and unregister your material properly as well

[drowsy pagoda]

Yeah, your way does seem easier. Thx for the tip.

[rustic rain]

It's more about changing API though. My approach with adding RenderMesh in 0.51 broke horribly after 1.0 changes 😅

So better not repeat mistakes

[drowsy pagoda]

ah good point

[muted field]

is it normal for my jobs to be idle for so long when running an IJobParallelFor ?

don't understand why they wait so long

the job lasts 0.004ms then they idle for such a long time

[rustic rain]

what's happening on main thread here?

[muted field]

not a lot just generating mesh data

instantiating them in the scene etc

oh that might be why because it calls the job after instantiation

[rustic rain]

Most probably your jobs are just scheduled with a huge gaps inbetween?

[muted field]

i need to do all the jobs first then instantiate and apply the data after

rather than instantiate then job for that prefab and repeat

[muted field]

yeh thats what it is i call them in a loop after instantiate

not sure if its worth changing that im not likely saving any time

unless unity optimises their instantiate method

[rotund token]

already done a 180 on aspects

going to make building a requirement library so much easier

[frosty siren]

i don't use unity's Graphics package so can't tell what can possibly go wrong. Docs says that RenderMeshArray filled during baking stage. How you actually modify this array?

[frosty siren]

How can I get and access state of ISystem through World.GetOrCreateSystem<TISystem>()?

It returns only SystemRef which allow access struct itself and some SystemHandle thing, which I even don't know to use for

It looks like I have no way to manage ISystem systems in a way to enable/disable them when i want to

[rotund token]

ResolveSystemStateChecked can do it but it's internal
ResolveSystemStateRef from WorldUnmanaged

[rustic rain]

why not? just get system state and modify it

[frosty siren]

it requires unsafe context ughhh

[rustic rain]

has it ever been a problem though?

[frosty siren]

no problem with unsafe stuff at all, but you know creating separate asmdef for things which needs control over systems

[rustic rain]

why?

I just give internal access to everything

[frosty siren]

how?

[rustic rain]

InternalsVisibleTo and to main namespace

from which everything else branches

[frosty siren]

hmm, didnt't know about that, thank you!

[rotund token]

public ref SystemState ResolveSystemStateRef(SystemHandle id)

isnt internla

Or unsafe

[frosty siren]

I see only World.Unmanaged.ResolveSystemState which returns pointer

I'm on 0.51

[rotund token]

oh

yeah well thats all you got then

in 1.0 it returns as ref handle

[robust scaffold]

What do you mean?

[drowsy pagoda]

I figured it out the hard way 😉
#archived-dots message

[frosty siren]

It seems like EntityQuery.ResetFilter only resetting SCD and component-change filtering, but how reset OrderChange filtering?

Because there is only place where _Filter.UseOrderFiltering = true; happens in EntityQuery code

[robust scaffold]

What do you mean?

[frosty siren]

1.0 ?

[robust scaffold]

yep

[frosty siren]

😬 entities giving me a subtly hint to update to 1.0

it is a 3rd time for a day when i speaking with people from future, when they have more progressive API then me 🙂

[robust scaffold]

Well, the only reason to be using LTS is for production development and if you're attempting to use 0.50 for production, uhhh.

[clever cobalt]

Is it possible to use interfaces with native arrays?

or is there some other way of using interfaces with arrays in jobs?

[frosty siren]

No, of course not. But if want to update all stuff i have to 0.51 and then to 1.0, so I still on 0.51

[frosty siren]

in what way?

[clever cobalt]

public interface IInterface {
  public void Run(SomeJob job);
}

public struct SomeJob : IJob {
  public NativeArray<IInterface> thingsToRun;
}

[frosty siren]

T in NativeArray should be a struct (in my collection package version at least, because future versions may require a unmanaged as T), so no, you can't use interfaces

[robust scaffold]

No. What you can do instead is:

public interface IInterface {
  public void Run(SomeJob job);
}

public struct SomeJob<T> where T: unmanaged, IInterface : IJob {
  public NativeArray<T> thingsToRun;
}```

[clever cobalt]

Thanks! I will look into it

[dense crypt]

Does full documentation work for you guys in Rider for DOTS? I can only ever get the summary to show up, not remarks or others. See the image for an example.

In this case there should be a remark that IsEmpty is faster for == 0 checks, as evident if you navigate to the function

[robust scaffold]

@proud jackal Personal preference but I dont think the ManagedAPI following SystemAPI needs the API. It should be SystemAPI.Managed.GetComponent<>(). Like how world has world.unmanaged and not world.unmanagedWorld.

[robust scaffold]

Remarks dont show up for me either.

[robust scaffold]

It shows up once the full thing is typed out.

[dense crypt]

I can't seem to get that either :/

[robust scaffold]

That second ss is from me hovering over the method.

[dense crypt]

oh yeah that works for me

hmm

Guess I'll have to check if there's a setting to always show that tooltip, would be so much more useful than the quick short one imo

[rustic rain]

you definetely don't want that, because it's the reason why ECS exists in the first place

it's slow

in ECS instead you process each "interface" in independent query

[robust scaffold]

Interfaces are fine if you want generic jobs though

[rustic rain]

talking about exact use case was mentioned

kind of what I meant actually

that's one way to do it

[drowsy pagoda]

Before when building on top of existing build, it would take 1-2 minutes. But now when building on top of existing build, it seems to do it from scratch each time ~7mins. Is that just a 1.0 thing, or is there a way I can restore the original behavior?

[robust scaffold]

mono development build?

[drowsy pagoda]

yeah

[robust scaffold]

no clue then, dots shouldnt have any effect on compilation. It's just a pile of c#

[rotund token]

are you on burst 1.8?

our build times at work went from 10min to over 40min and it's 35min of burst

same version of unity for last year

[drowsy pagoda]

no, i'm on 1.7.3

[rotund token]

that is so old o_O

[drowsy pagoda]

lol sorry, typo

[rotund token]

haha ok that makes much more sense

[drowsy pagoda]

Yeah, my build is giving me that failed to build entity scene crap again. I have a feeling that something triggers this during baking while building, and an exception get's thrown which then crashes the whole baking process and the build builds everything else except the entities that needed to be converted to the scene.

I'm gonna stash these changes, rollback, and build and see if it builds successfully.

[safe lintel]

so is content management == dots addressables? tbh i thought it would deal with entity prefabs and not gameobject resources

[rotund token]

addressables is all about solving having to load every asset into memory at once

which is currently an issue with dots

that all said, ContentDeliveryService seems like it can load subscenes from a very quick look into it the other day

and subscenes contain entities

[safe lintel]

i was kind of hoping to just tick a box in the editor and not even need to make a subscene with an entity, kind of like how you can do that with instantiateasync-gameobject-nickname and do something similar in dots

[robust scaffold]

Im gonna try and hook up the native dots sprite renderer again. Performance of it is horrible but it works.

[safe lintel]

wonder if the updated megacity sample will use gameobject audio or just nix it altogether

[balmy thistle]

oh that's interesting, how are you doing the occlusion?

I made a Unity game with pixel perfect occluded shadows but it required a lot of custom rendering

[robust scaffold]

Doesnt work :(

[robust scaffold]

My own custom light renderer

[balmy thistle]

sounds about right

[robust scaffold]

And please, poke the 2d sprite renderer guys to reconnect sprite renderer group API.

It worked back in 0.17 so... plz.

[balmy thistle]

If you haven't already, you probably want to mention how relevant this feature is to you on the DOTS Roadmap page: https://unity.com/roadmap/unity-platform/dots

[robust scaffold]

Yea, already did.

I checked and my own message was already there from a year or so ago.

Ugh. I guess I can go back to work rolling my own sprite renderer. Very annoying.

[rotund token]

bit of a throw back but you've reminded me of it, first library i ever wrote for dots was a vision library. this was way back, probably <0.0.12 (not 0.12)

good times

my dota river clone ^_^'

yep i was spot on!

        "com.unity.burst": "1.0.0-preview.6",
        "com.unity.collections": "0.0.9-preview.16",
        "com.unity.entities": "0.0.12-preview.29",
        "com.unity.mathematics": "1.0.0-preview.1"
    }```

good times

[safe lintel]

dota clone? nice 😄

[rotund token]

was never a game, just a sample scene as an inspiration to test tech

[safe lintel]

i have spent time wondering how the hell a dota ability system would look like in ecs

[rotund token]

after i finish my requirement system (which shouldn't be to hard since i'm going to split off and re-use my conditions from my effects library)

i would like to look at an ability system

probably just loosely base it off Unreal's Gameplay Ability System for usability

[robust scaffold]

how would aspects help with that system? You mentioned last night

[rotund token]

oh just writing the conditions
because this is one place that is many write, 1 read

[covert lagoon]

If it would be a multiplayer game with Netcode for Entities and abilities can't be used often, maybe they could be RPCs.

[rotund token]

previously i had helper structs / extension methods

which i can just cleanup with aspect

[rotund token]

i wouldn't use RPCs

i'd want my system to work with or without netcode

[covert lagoon]

But you can only use abilities every few seconds at most, right?

[rotund token]

my game uses netcode, but i write all my libraries standalone without netcode

[covert lagoon]

So maybe you could add and remove a component.

[rotund token]

i always test with a minimum of 100k actors

[covert lagoon]

Damn.

[rotund token]

some libraries i test a lot more

my local avoidance 250k

my effects 10mill

etc

[covert lagoon]

Then I guess you would just add an extra field to your component that stores player/character input.

[rotund token]

but 100k is bare minimum my library must support for me to be happy

[covert lagoon]

RequestedAbility or something like that.

When the player/character isn't requesting to use an ability, it's some kind of null value.

[rotund token]

why can't use 2 abilities at once

[covert lagoon]

The same frame?

Do you test with 100k abilites per character class too?

[rotund token]

no that'd be unrealistic

i haven't built this yet

but i imagine 100 abilities would be reasonable

and i made abilities quite generic, like cutting a tree is the same thing as casting a fireball

anyway as said, i haven't built this yet and i only have a vague idea how to implement

the tricky thing i'm mostly thinking about is timings on client vs server

something our ability system at work has had issues with

(which is dots, but i didn't write it)

[safe lintel]

is this a scheduling conflict? feels like something i should be able to fix but having a hard time trying to figure it out

[rotund token]

sounds like your using EM after doing an Update on Handles

[safe lintel]

yeah seems it but I swear I shouldnt be doing that. just updated several hundred instances of translation/rotation etc to the new v2 transform and this was working previously in v1. not really sure why I'd be getting this error now as I definitely didnt add any em use during upgrading

[rotund token]

that's a happy surprise, IJE seems to be able to handle a static Execute signature
never mind it only works until clears the temp cache or make a change ^_^'

[full epoch]

Is possible to get RigidBodyAspect somehow in IJobChunk?

[rotund token]

try the RigidBodyAspect.ResolvedChunk

or is it RigidBodyAspect.TypeHandle

something like that

one of the extra things it generates provides you the data you need

yeah RigidBodyAspect.TypeHandle

then call Update(ref global::Unity.Entities.SystemState state) like a normal type handle in your system

and in the job call Resolve(ArchetypeChunk)

[full epoch]

thx

[rotund token]

which gives you an indexier, which you can index to get your RigidbodyAspect

[robust scaffold]

Sprite renderer isnt on the list, so sad. Tiny 2d sprite renderer is dead.

[rotund token]

the 26th of November will forever be known as "KornFlaks writes his own sprite renderer day"

[robust scaffold]

i dont want to though, it's so painful

it's just that companion GOs are very broken with netcode

[rotund token]

that's i wrote my own little simple hybrid system for it

[safe lintel]

hm maybe its an isystem bug? error doesnt show after reverting back to systembase

[brave field]

😱 Anyone notice that Unity 2022.2.0f1 can't build android? Not sure whether this issue will be fixed when going public

[scarlet inlet]

Probably still working on the Vulkan transpilation. Remember that Android is also Quest, Set top boxes, etc. It's a real bugaboo. I'd expect a little delay to block off non-working translations.

[robust scaffold]

.... well. I guess I wont try building then

[rotund token]

Are you using the logging package?

Or was that just a dependency

I haven't seen anyone else use it

[robust scaffold]

Dependency. Netcode requires it

Physics and companion GOs also break the build

Yea, just everything is broken it seems. Oh well

[rotund token]

Ah shame. I've been trying to get myself to use the logging package more instead of debug log

[robust scaffold]

Gonna build an empty scene. Lets see if this works.

[rotund token]

Seems to be burst at fault for your failures?

[robust scaffold]

No systems being added. If this doesnt work. Nothing will.

[rotund token]

Tried an earlier version?

[robust scaffold]

Not yet, gonna see if this runs without error first. Building an empty scene takes a while.

Ha, no

[jaunty sand]

Are you using IL2CPP? What's your code stripping level?

[rotund token]

how do people feel like linq like methods in dots/burst?

            public NativeArray<ConditionSchema> ConditionSchemas;

            private void Execute(Entity entity, in DynamicBuffer<GlobalCondition> globalConditions)
            {
                foreach (var condition in globalConditions.AsNativeArrayRO())
                {
                    if (!this.ConditionSchemas.Any(new AreEqual(condition.Key)))
                    {
                        Debug.LogError($"...");
                        continue;
                    }```

i wrote a whole range of them ages ago

wrote a whole range of them ages ago and barely use them

Where, WhereNoAlloc, Select, All, Any, FirstOrDefault, IndexOf, Min, Max kind of stuff

[rotund token]

i'm having no issue building with physics and logging package

[rotund token]

threw netcode in the library as well and had no issue making a build

[robust scaffold]

Hrm....

[robust scaffold]

Mono, no stripping

[misty wedge]

Can you not set the enabled state of a RW component inside an aspect if you also need to access it?

Adding an EnabledRefRW tells me I can't have both

[robust scaffold]

Limitation of aspects right now.

[robust scaffold]

Im making a fresh project in 2022.2F and it's building properly. Transferring over folders manually and all are building properly. Hrm, I think the upgrade from 2019LTS might have broke something

[misty wedge]

What error are you getting?

[robust scaffold]

A bunch of burst errors. And with this new build, none of the burst errors but I do have a type not found error so hrm

[misty wedge]

Alright, when I updated my project settings broke, that's why I was asking

But the error wasn't a burst error, and I only got it on building

[robust scaffold]

Yea. It builds without problem. Seems like a problem with an old project repeatedly upgraded from an old version

[misty wedge]

Does the newest unity version still have so many issues with entity headers breaking in baking? Or is it fine to upgrade

iirc I tried b13 and that was borderline unusable

[robust scaffold]

Yea, the 2022.2F and preview builds are fairly stable. I still occasionally have crash to desktop due to the baker stalling out but that's every hour instead of every single time the files change

[misty wedge]

Latest I see is b16?

[robust scaffold]

You need the direct link, give me a min

[misty wedge]

[robust scaffold]

unityhub://2022.2.0f1/1c1f8590be28

type that into your browser's url

[misty wedge]

Did a dev post this?

Or how was this figured out

[robust scaffold]

no clue

i just have the link saved

[misty wedge]

haha, alright

I'm assuming this matches entities to .15?

[robust scaffold]

preview build yea

[misty wedge]

Any idea if il2cpp builds work on that version?

[robust scaffold]

maybe? I just got mono building and havent tried il2cpp yet

[misty wedge]

Awesome, thanks for the info

I'm assuming 2022.2 is releasing soon then

[kindred nacelle]

Does anyone know adding a tag is a structural change in DOTS alpha 1.0?

[robust scaffold]

Yes. It's still a component

[kindred nacelle]

What the best practise to do behaviour like this? Make Component with flag value?

if i want to do many adding or removing tag like info

[robust scaffold]

What is "this"?

I dont know what your code is nor what you want to achieve

[kindred nacelle]

I want to define a large set of interactions at objects and specify this actions by tags

[robust scaffold]

Will you be needing to change those tags every frame or so?

[kindred nacelle]

Yes, almost every frame

[robust scaffold]

Then use an empty component that inherits IEnableableComponent. Toggling enabled / disabled is not a structural change.

[kindred nacelle]

Oh, yes I forgot about this. Is EnableableComponent are include object in queries, if it disable?

[robust scaffold]

No, if you use the enabled mask in an IJobChunk and is automatically filtered out if you use IJobEntity

[kindred nacelle]

Thanks

[jaunty sand]

I was going to suggest nuking the library folder given the multiple upgrade context. Glad to hear it's sorted out now though

[robust scaffold]

Yea, I made a new project and copy pasted all my asset files. Should've did that the first thing as I was changing major versions (from 2021LTS to 2022.2)

[misty wedge]

does netcode support transforms V2 in pre.15?

[robust scaffold]

yes

[misty wedge]

If I need a deterministic random seed in a networking context, NetworkTick should be the same for predicted entity on the client and server inside a prediction system right?

Also saw that SystemAPI now supports type handles, removes so much boilerplate

Really nice

Especially with the bug fix to inline SystemAPI calls for created jobs

[rustic rain]

anyone has any idea what is current version for API for source generators in 2022.2?

[misty wedge]

What do you mean?

[rustic rain]

Microsoft.CodeAnalysis.CSharp version for 2022.2
Which is it?

I'm learning source generators and 3.8 version mentioned in manual seems sus

[misty wedge]

Ah, I have no idea

haha I'm assuming this was you @proud jackal

[proud jackal]

Hahaha whaaaAaAaat i would never :3

[proud jackal]

Incremental Generators in 4.0.1 is compatible too

[rustic rain]

does that mean I can use 4.0.1 package?

I am really just learning and trying to make my first field generator, so fancy words don't work on me 😅

[misty wedge]

Are shared component type handles with SystemAPI not working with codegen yet?

I get an error

I was wondering since I don't see it on the list of known issues

[rustic rain]

they have their own type handle type

[misty wedge]

Well yes

But the codegen is breaking

Temp\GeneratedCode\Schnozzle.WorldGeneration\WorldFeaturesSystem__System_502980019.g.cs(496,97): error CS0102: The type 'WorldFeaturesSystem' already contains a definition for '__Schnozzle_Core_Components_WorldIdentityShared_SharedComponentTypeHandle'

[rustic rain]

how does it even work for you in pre codegen code?

[misty wedge]

What do you mean?

[rustic rain]

Compiler should not even allow this to compile

[misty wedge]

It doesn't

It works if I don't use SystemAPI

(since that won't codegen the component handle then)

[rustic rain]

well, your job field for shared comp doesn't match output of SystemAPI

[misty wedge]

???

That's not even what the error message says

[rustic rain]

Are you doing ComponentTypeHandle<SharedComp>?

[rustic rain]

oh ok

[misty wedge]

Of course

lol

[rustic rain]

so, how does it look in SystemAPI?

with*

[rustic rain]

🤔

no idea then

allthough

[misty wedge]

It's getting put into the code-gen'd file twice for some reason

[rustic rain]

you might want to check codegened file

[misty wedge]

I guess it's some weird edge case

[rustic rain]

🤔

[proud jackal]

You should be able to use 4.0.1 in Unity 2022.2.10b+ (and possibly even earlier than that, tho i don't remember the version we added the support 😆)

[rustic rain]

could you check? or maybe I somehow?
Manual mentions 3.8.0 only

oh wait

nvm you meant Unity version

😅

[proud jackal]

Alsp that edge case is odd! Could you share a minimum repro for me to look at?

[proud jackal]

Yuppp.. docs weren't updated but the version works

[misty wedge]

If I can replicate it outside of this file sure

[rustic rain]

that's good. All .net manuals are updated to 4 version now and as soon as I tried to use 3.8.0... it wasn't good kek

[proud jackal]

Oh fun, well lemme know how it goes i would definitely recommend not using ISourceGenerator and using Incremental generator instead :3
Here are some good resources i can recommend:

[robust scaffold]

@proud jackal Are there any efforts to include a [WithOrderFilter] to IJobEntity?

[robust scaffold]

Just tried, i can not replicate the same issue. Codegen works for me.

[misty wedge]

It breaks if you request a shared component inside an IJobEntity and also get the shared component type handle with SystemAPI
https://hastebin.com/odoxuyiniv.hs

[proud jackal]

You're the first to request it, but duly noted ✍️

[robust scaffold]

Huh, would've seemed logical to expose all functionality of a query as tags for IJE.

[proud jackal]

Thx for sharing! Imma take a look 😄

[robust scaffold]

That's an odd use case. What are you trying to do with a component tag inside a IJE?

[misty wedge]

Seconding this, IJE scheduling with a SharedComponentFilter would be really nice

Probably not with a tag but an extension function

[robust scaffold]

new IJE{}.WithSharedComponentFilter(value).Schedule()? Kinda going back to lambda EFE at that point...

[misty wedge]

A million times better than redefining the query before scheduling it IMO

It's the only one that you can't do with a tag since it requires a value

[robust scaffold]

The one thing I wish IJE had from EFE is the .WithStoreQuery(ref value) or whatever it was called.

[misty wedge]

Yes, that one would also be nice

And I think the issue with EFE wasn't the extension functions, but the lambdas

[robust scaffold]

And scheduling wasn't burstable.

And if you used intellisense, typing anything inside the EFE lambda would stall the IDE with all the options.

[misty wedge]

Can you predict an RPC call for a predicted ghost?

Or do you need to use input commands

e.g. for using an ability, sending an RPC once instead of sending the ability ID each frame

I'm guessing not since you can't get the RPC for a specific tick

[rotund token]

it's always fun when you load up a project, upgrade libraries, fix compile errors then it just infinite loops on GameView.Repaint even after a close/load

is there no way to enter safe mode without a compile error? guess it's time for a rogue /

[robust scaffold]

Can you have entities inside blob assets at bake? Do they properly remap when streamed in?

[rustic rain]

No

[rotund token]

only icomponent and ibufferelement will remap

[robust scaffold]

ugh

[rotund token]

i suspect unmanaged isharedcomponent is possible but just wasn't setup because of the historically they were all managed

[robust scaffold]

i guess I can use a giant buffer. It is practically the same thing

As long as the buffer itself doesnt change capacity, I can pass around the pointer to buffer header and it's a automatically managed blob asset.

[rotund token]

unity can still move the buffer to a new chunk

if anything in that chunk changes

[robust scaffold]

Nah, it's a singleton. Shouldnt change.

[rotund token]

or move it within the chunk if the archetype changes

seems incredibly unsafe ^_^'

[robust scaffold]

unsafe? I prefer highly performant.

although I spent nearly 2 hours earlier today wondering why unity hard crash to desktop whenever I press play. I realized that I had a pointer shift occur before write to a pointer in a for loop so it was writing 700 elements beyond the end of the allocated buffer, resulting in a segmentation fault on the C++ side.

As I said, highly performant. Bringing the user instantly to the end state of closing the program.

[robust scaffold]

Huh, it's back

[rotund token]

never went away

just much rarer thankfully

[robust scaffold]

Yea. This time I created a new baker and everything decided to die.

[viral sonnet]

tertle, did you get the PropertyInspector working in pre-15? namespace should be Unity.Entities.UI but I can't get it working

aw man, forgot the reference in my asmdef. haha

SystemAPI.GetComponentTypeHandle
❤️

[viral sonnet]

now i need to find out how multiple usage of SystemAPI.GetEntityTypeHandle() reacts in one system. i certainly couldn't reuse the same handle for 2 different jobs

[rotund token]

yes

[robust scaffold]

No? You should be able to set it equal to a variable then reuse it.

[rotund token]

oh yep you figured it out

yeah they moved it to a new asmdef

[viral sonnet]

yeah, assembly is Unity.Entities.UI.Editor and namespace is Unity.Entities.UI - glad they moved it

[viral sonnet]

huh? that threw a lot of errors if i reuse the handle. that was in 1.0exp

[rotund token]

i've always re-used the handle

never had an issue

as long as you aren't running the jobs in parallel then the safety might complain

[viral sonnet]

oh, no, i'm talking nonsense but i needed to update before the 2nd job

[rotund token]

handle.update
job1 {handle = handle}
job2 {handle = handle}

should be fine (as long as job2 depends on job1 probably, not sure about running in parallel)

[viral sonnet]

maybe i need to test again. slowly going through the systems. can't remember exactly where that system was but i'll find it 😄

[rotund token]

spent the last 2 days just building auto formatting rules for my code/libraries

[viral sonnet]

wow, what is it able to do now?

[rotund token]

oh just basically everything

format xml, enforce expression bodies, re-order file layouts

add headers, deleting double lines, add/remove spaces

i've currently got it running every time i save

not sure that'll stick but we'll see

one thing i keep switching back and forwards between

is expression bodies on methods

i keep thinking, yeah expression bodies are great
then I see my code switched to

            new CreateMapJob
                {
                    ConditionSchemas = SystemAPI.GetSingletonBuffer<ConditionSchema>().AsNativeArray(),
                    GlobalEntities = this.globalEntities,
                }
                .Run();```

-_-

[viral sonnet]

yikes 😄

that's too much! 😄

[rotund token]

think i'll just disallow on methods, enforce on properties

a sane person would be like, case by case basis

but not me

[viral sonnet]

i'm not a fan of expression bodies in general. but for properties it's okay

for methods, i dunno. make some damn curly braces

[rotund token]

i'd like to allow them on operators

but rider doesn't differentiate between other methods

[viral sonnet]

can't even filter for keywords? just method, yes/no?

[rotund token]

only these options

[robust scaffold]

Huh. So you can't nest subscenes inside subscenes?

[rotund token]

i always always surprised this worked for you tbh

[robust scaffold]

Well it died now. Hrm. Gonna find another way

[rotund token]

i've just grouped them with a few prefabs

[robust scaffold]

I hate that prespawned entities in netcode must be assigned a gameobject beforehand

[rotund token]

not sure what you mean or the problem you have

[viral sonnet]

found the system i was talking about. removing the update before the 2nd job results in

InvalidOperationException: Attempted to access the Unity.Entities.EntityTypeHandle Process_AddedEffects_Job.JobData.Entities_ReadHandle which has been invalidated by a structural change.
the good news. SystemAPI.GetEntityTypeHandle() works fine

[robust scaffold]

I have a tilemap, 2048x2048. I want an entity every 8x8 tiles. That means about 66k entities. I dont want to manually assign 66 thousand entities.

[rotund token]

ah how are you doing a structural change?

i imagine you're doing something like
GetSingleton

[viral sonnet]

single schedule job that reacts to removed effects and then added effects

[rotund token]

is there a complete or something between these jobs?

[viral sonnet]

yes

[rotund token]

ah yeah ok that makes sense

update is valid until a structural change

that's why it has to update!

(and global version)

[viral sonnet]

yeah, right. i'm surprised SystemAPI.GetEntityTypeHandle() gets that

[rotund token]

think it just calls update at that point

[viral sonnet]

yeah, maybe it just creates 2 handles

(currently looking at the codegen)

[rotund token]

Update is free for EntityTypeHandle (it's a no-op without safety)

and it's a single uint assignment for components/buffers

[viral sonnet]

ok, it generates 1 handle and calls update 2 times. like it should. cool

[rotund token]

so it's really no big deal if you have to update multiple times in a system

[viral sonnet]

system code gets nicer every new version 😄

[rotund token]

did you see dani leaked default interface methods 😄

it's all we need

no more oncreate/ondestroy

[viral sonnet]

are you talking about the IJobEntityChunkBeginEnd?

[rotund token]

#archived-dots message

[rotund token]

no

[viral sonnet]

oh okay

[rotund token]

interface with
void OnCreate() {}

so you don't need to implement oncreate/ondestroy

if you don't use them

[viral sonnet]

nice!

[rotund token]

with all this systemapi stuff my oncreates are often empty now

so it'll be so nice to just not have them

[safe lintel]

wait whats the api helps with Oncreate?

[viral sonnet]

yeah i just have queries and some singleton dependencies now in create

[viral sonnet]

you can remove empty OnDestroy/Create now

but i have no idea how that works because i get errors 😄

[rotund token]

you can't yet

[rotund token]

read ^

[viral sonnet]

ok 😄

[rotund token]

default interface methods will allow this, and this version of unity supports it

[robust scaffold]

This is pain.

But I guess this is a viable way to clone prespawned entities without going through the hoops of baking.

[rotund token]

Seems reasonable tbh

Could open, close, scene to make it more convenient

[robust scaffold]

I guess

It's just odd, but it does work

[rotund token]

when does it even need to change?

[robust scaffold]

It's manually triggered by a button in the inspector

[rotund token]

yeah

but i mean, once you set this up once, how often do you even need to run it again

[robust scaffold]

Every time I change tilemap dimensions. As long as I dont resize the TM, it doesnt change.

[safe lintel]

@rotund token wait is that to just get rid of typing oncreate or to auto cache state.GetComponentTypeHandle? i dont quite follow

[rotund token]

you wouldn't need to implement oncreate

    [UpdateInGroup(typeof(ConditionsSystemGroup))]
    public partial struct ConditionAllActiveSystem : ISystem
    {
        /// <inheritdoc />
        [BurstCompile]
        public void OnUpdate(ref SystemState state)
        {
            new ConditionAllActiveJob().ScheduleParallel();
        }

        /// <inheritdoc />
        public void OnCreate(ref SystemState state)
        {
        }

        /// <inheritdoc />
        public void OnDestroy(ref SystemState state)
        {
        }
    }```

could become

    [UpdateInGroup(typeof(ConditionsSystemGroup))]
    public partial struct ConditionAllActiveSystem : ISystem
    {
        /// <inheritdoc />
        [BurstCompile]
        public void OnUpdate(ref SystemState state)
        {
            new ConditionAllActiveJob().ScheduleParallel();
        }
    }```

you can already use SystemAPI to create all your type handles, lookups etc

[robust scaffold]

Does anyone know if setting lengths of buffers in the baker inflate the size of the subscene? Should I instead be using EnsureCapacity() and then resizing the buffers at runtime since they're all 0?

[rotund token]

yeah whatever size you set the buffer is the size of the buffer that will serialize

[robust scaffold]

I'm just worried because I have these giant 2M float sized buffers that are setup at runtime but not at bake.

[rotund token]

hmm

i can't see subscenes using compression anymore

doesn't seem to use the codecservices anymore

that seems unlikely, just not sure where it'd do it now

[dense crypt]

how can i hide the sytems showing up in the entities hierarchy, or do i just have to live with it?

[robust scaffold]

Either select the Authoring mode in the orange circle or live with it.

[dense crypt]

For some reason that also hides my entity??

[robust scaffold]

It hides entities not inside subscenes yes.

[dense crypt]

Yeah I just realised what you meant by authoring mode, hmm

[robust scaffold]

if you're manually spawning these entities and still want to see them, then you'll have to live with it.

[dense crypt]

Yeah I'll make do, thanks for help 🙂

[robust scaffold]

If you really want to remove the systems, you can put together an editor extension script to modify the entity hierarchy list to filter out systems

[rotund token]

reason #47 to use my core library

lets you hide systems

[viral sonnet]

what happened to the entities hierarchy filter? filtering comps doesn't work anymore

[safe lintel]

i think its c= not c: now

[rotund token]

which is a really weird change imo

considering : is standard filtering in project window etc

and the search window

[viral sonnet]

no i get the change from : to = (which is a bad change btw) - it still doesn't work. is it only for me?

i'm trying to filter a tag comp

[safe lintel]

is it possible to do filter multiple components?

@viral sonnet i dont know but i even have a different dropdown box from tertle

[robust scaffold]

Tertle's dropbox is his own extension.

[viral sonnet]

tertle has his custom filters

[safe lintel]

oh looks so good thought that was standard 😦

[rotund token]

i forgot i added none as well

[rotund token]

but yes i consider this mandatory for the package

1.0 is currently a huge regression to 0.17 entity debugger for filtering

[safe lintel]

possible to filter multiple components? i cant figure it out if it is

[rotund token]

only with my librayr

that's what this is

by default it uses Any

[safe lintel]

ah 🙂

[rotund token]

which is useless, i really don't understand who would ever want to use this

[robust scaffold]

entity debugger my beloved..

[rotund token]

i would say >99% of time All would be the desired filter

[robust scaffold]

i am 95% there to porting over the entirety of entity debugger from 0.17

[viral sonnet]

so can you guys filter in 1.0pre15? 😄

[rotund token]

yes

[safe lintel]

you gonna port the chunk visualization? never personally had a need for it but thought it was a neat tool

[viral sonnet]

wth, why is this not working for me. 🤔

[safe lintel]

and i have to assume that visualizer was really useful for others who absolutely needed to optimize chunk use

[robust scaffold]

I'm no smart enough to change anything with the debugger though

@rotund token If i port it, are ya willing to take up the job of maintaining it in your library?

[rotund token]

no

i'm done with ED

[robust scaffold]

😢

[safe lintel]

not even hesitation 🙂

[rotund token]

would be like an alcoholic taking a drink

it took a lot of work to stop using it

[rotund token]

i'm testing more, i can break it with certain components

which is not great

[robust scaffold]

Im gonna do it anyways. Because this alcoholic had their drink taken away cold turkey and I've been getting the shakes ever since.

[rotund token]

actually what i'm finding is

it works in editor mode

not in play mode

wait no that's not even true

yeah super busted enzi

i'm just going to fix it with my filter extensions -_-

[viral sonnet]

ok, damn

[rotund token]

ahhhhhhhhhhhhhhhh hang on

i'm looking at source

first thing

            {
                // Temp patch: Using `All` since most users seem to prefer that behaviour.
                // The real solution is to properly support entity queries in search.
                All = componentTypes.Set.ToArray(),
                Options = EntityQueryOptions.IncludePrefab | EntityQueryOptions.IncludeDisabledEntities
            }, k_UnmatchedInputBuilder.ToString());```

they've actually changed it to All

woohoo

second thing, no idea why it's broken, the query just seems to randomly empty

actually @viral sonnet it seems to work fine

it was my extension that broke it for me because of the any => all switch

[viral sonnet]

just restarted the editor in hopes it would fix something. no matter which comp i pick i juts get every entity returned

[rotund token]

definitely works for me now that i updated my extension to filters

[viral sonnet]

ah yeah i'm in runtime

[rotund token]

ignore that, missread my data

runtime is fine

[viral sonnet]

can you test with a tag comp?

eh, don't think it matters much.

my filtering also doesn't work in editor mode

ok, let's take a look at the diff set from 1.0exp to pre

[rotund token]

definitely don't have my filter or library somewhere?

essentials or something

[viral sonnet]

nope

haha, yeaaaah. i'm not using your library but i found customHierarchy ... 🤦‍♂️

well, fixed. sorry for wasting your time :/

[rotund token]

not a waste, you pointed out my library was broken ^_^'

[viral sonnet]

hehe 😅

[rotund token]

anyway i'm super happy they changed it to All

switched my filter to give Any option instead for super rare cases

[viral sonnet]

yeah about time. i love the defensive comment. "most users prefer it that way" - instead of, it never made sense to begin with 😁

[robust scaffold]

It's back baby

Horribly optimized but I'm shocked with only a few cleanups here and there, it functions.

[viral sonnet]

whoa cool!

[robust scaffold]

My god, i'm crying. It's as beautiful as the day we lost her.

Just ignore the errors, i've gotta clean up the backend. Use bursted stuff as well

[worn umbra]

The 2022.2.0f1 is really unstable for me. It often freezes when I hit the play button. Then I have to force kill the task. Do you have the same experience? 🙈

[viral sonnet]

I'm really missing the chunk utilization

[robust scaffold]

Thats a uncaught native asset database crash. Happens occasionally to me as well. Cant get it nailed down yet for a repo though.

[robust scaffold]

Yea, it's so good to click on an archetype and then see all entities that are part of the archetype as well

The problem is that entities debugger is written in very very slow imgui

Am I insane enough to port this to UIE? Hrm...

This actually was relatively painless to revive from the dead. So my masochistic tendencies remain unfulfilled. I'm gonna try it.

It looks beautiful though. Hrm.

I need names, what do I call this... EntityDebuggerV2. Yes. Everything DOTS has to have a V2 and V3 version

[rotund token]

1.0pre

[robust scaffold]

EntityDebugger 1.0 exp.1 YES

Before I go off and slice this thing apart. Here's an untested but maybe functional EntityDebugger for 1.0 pre.15

It seems functional but I havent put it through the ringer to see if it explodes or anything

This must be placed in the uppermost level of Assets/ folder because of hardcoded path. Sorry. And dont rename the folder either.

[hushed fjord]

when should I use an aspect vs just doing the functionality in a system? in my case I just need to turn raw player input into something the in-game character can interpret

[rotund token]

I would say first thought is if the aspect is going to be used in multiple places

[hushed fjord]

ok

so in my case probably don't use an aspect because only the player needs it (?)

[rotund token]

well just because it's only player, doesn't mean it can't be used in multiple places

but if it's just used in a single system, personally i would not bother with an aspect

it seems like an extra level of abstraction for no reason

[robust scaffold]

Do you mean using the transform aspect or using the LocalTransform component or making a custom aspect for this?

[hushed fjord]

making a custom aspect

[hushed fjord]

curious, how would I use it in multiple places?

[rotund token]

i dont know what you're making

[hushed fjord]

oh ok

[robust scaffold]

Do you plan on using the netcode package?

[rotund token]

maybe it was an inputaspect, that converts raw input with sensitivity etc and you could use it for plane control and player camera etc

[hushed fjord]

no

netcode is for multiplayer, right?

[hushed fjord]

ah I see

[robust scaffold]

Yep. if ya dont plan on using netcode, continue listening to tertle.

[hushed fjord]

how do I get a reference to a component on an entity? I'm planning to pass it into an IJobEntity and then change its values (or should I pass in the entity itself?)

[hushed fjord]

right now I have

[BurstCompile]
        public void OnUpdate(ref SystemState state)
        {
            var playerEntity = SystemAPI.GetSingletonEntity<PlayerTag>();
            var inputComponent = SystemAPI.GetComponent<CharacterInput>(playerEntity);

            var deltaTime = SystemAPI.Time.DeltaTime;
            new ReadInputJob
            {
                InputComponent = inputComponent,
                DeltaTime = deltaTime,
            };
        }
``` and 
```csharp
[BurstCompile]
    public partial struct ReadInputJob : IJobEntity
    {
        public CharacterInput InputComponent;
        public float DeltaTime;

        [BurstCompile]
        public void Execute()
        {
            var horizontalInput = Input.GetAxis("Horizontal");
            var verticalInput = Input.GetAxis("Vertical");

            var direction = new float2(horizontalInput, verticalInput);
            direction = math.normalize(direction);

            InputComponent.Direction = direction;
        }
    }
``` but wouldn't I have to specify that it's read and write somewhere in there?

[safe lintel]

Loading Entity Scene failed because the entity header file couldn't be resolved. oh damn thought 2022.2.0f1 and pre15 fixed this

[worn umbra]

haha, I think you are just lucky for a few minutes, it will happen soon again. 😄

[viral sonnet]

that's a pain to debug. my change filter doesn't work 😦

[rotund token]

i was actually writing tooling for this a while ago

to use heuristics to detect change filters running more frequently than they should

sadly never got around to finishing it though

[viral sonnet]

hm, i'm not finding the reason why this isn't working. version is bumped via componentLookup, yet the change isn't triggered. i've gone through every handle to eliminate any wrong bumps but just reads otherwise. so odd.

now i've thought about order but that shouldn't matter

[rotund token]

oh as in it's not triggering a change?

order shouldn't matter, at worse it'll frame delay

[viral sonnet]

yeah, chunk.DidChange is always false

[rotund token]

but it should always bump

it's not 2 jobs within the same system right?

they are in different systems

[viral sonnet]

yeah

state.LastSystemVersion is also correct. i'm looking at an error for something that's 2 lines 😄

[rotund token]

only thing i can think of

is if either a lookup or handle not having update called

that has safety off so it's not throwing errors

[viral sonnet]

hm, good call, let me check

[rotund token]

the only thing Update does (outside of safety) is update the global system version

if that's not bumped it's not going to trigger change

[viral sonnet]

hm, I have SystemAPI in place everywhere

[rotund token]

yeah it shouldn't be a concern

[viral sonnet]

but it must be something close to that

[light mason]

what is the recommended way to stop an entity from rendering ?

[rotund token]

there used to be a DisableRendering component

not sure if it still works in 1.0, haven't tried

looks like it still exists

[light mason]

is there a way to disable rendering without a structural change?

[rotund token]

I don't think so

Generally disabling rendering would be a long (relative) state change

[light mason]

does this not seem like a problem?

[rotund token]

how so

[rustic rain]

it does

[rustic rain]

why? It's literally disabling one of the heaviest system sets in whole dots, Nothing wrong with structural change here

[frosty siren]

Does ComputeBuffer make GC when we call Release()?

[frosty siren]

In IJobEntity if I want to set parameter to NativeDisableParallelForRestriction should I place it before parameter in Execute method?

[misty wedge]

Is there no way atm to query over an IEnableableComponent's value and also set whether or not the component is enabled?

[frosty siren]

How to properly dispose BlobAssetStore allocated while baking?

[rustic rain]

you should use baker's store I think

[frosty siren]

ok, but what if i'm 0.51 guy?

[worn umbra]

How come when I pass a component to parameter of IJobsEntity's Execute, it is allowed to be written in parallel, but when I use ComponentLookup and pass it to struct instance then it complains it cannot run parallel because it is not readonly?

[misty wedge]

Because if you pass it to IJE you can only write to the entity being processed for that chunk

It doesn't allow writing across chunks

ComponentLookup does allow that, which is why you can't schedule it in parallel

[edgy fulcrum]

@worn umbra there's always [NativeDisableContainerSafetyRestriction] on the specific ComponentLookup if you know for sure that parallel jobs will not modify the same enity

[rustic rain]

ConversionSystems have a field/property for BlobAssetStore

[worn umbra]

Thank you very much! Exactly what I need. 🙂

[worn umbra]

Thanks for the background about what is happening.

[misty wedge]

Be very careful with disabling safety though

[edgy fulcrum]

yup, cat here is very correct 😉

[misty wedge]

If you really need to write data across jobs, just schedule it sequentially instead of in parallel, or use an entity command buffer

[worn umbra]

I have multiple jobs that depend on each other, but they need to run in parallel. So the first job is calculating data for other jobs, the other jobs are waiting until the first job is done, but the first job must calculate the data in parallel. So the jobs are in parallel mode but running 'sequentially'. Disabling the restriction is the best way here. Otherwise, I would lose the power of parallel processing. 🙂

[remote crater]

Silly question: Can I edit IComponentData before conversion?

As a gameobject in a monobehavior?

I should probably just piece data into a gameobject componet for conversion

I think thats why I have a script called ConvertSillyHaveToDoThis, lol

its been so long tho

[edgy fulcrum]

@remote crater yeah there's a wholly new Baker system in 1.0 which might make this easier for you 😉

[remote crater]

TY, shunning the 1 for now

I'll be good to go,ty

[misty wedge]

What's the correct way to handle increasing deltatime in a predicted system? Since the prediction on the client may run multiple times, increasing the elapsed time too quickly

[remote crater]

you mean network?

[misty wedge]

Yes

[remote crater]

you run it like 10 tiems

[misty wedge]

NetCode

[remote crater]

I did this back in 2003

I write netcode from scratch

do it 10 times, average it

be lazy

[misty wedge]

What

[remote crater]

its like aim predicting

You send a ping

[misty wedge]

This is a question specific to Unity's netcode

[remote crater]

1/2 it is one hop

Well you can do it manually too 🙂

Add up 10 half hops, divide by 10

[misty wedge]

My question is what the correct way to handle it is according to unity

They already have client side prediction built in

[remote crater]

Yah, that rollback stuff is a given

I actually codisovered rollback like Libnietz to Newton back in 2003 too

Midway told me I was a noob and rollback would never work

now all the fighters use it lolololol

[misty wedge]

Unity doesn't use rollback netcode

It's server authoritive

[remote crater]

client side prediction is rollback

[misty wedge]

Fighters usually don't use server authoritive models

[remote crater]

the angle they hold the controller is the direction they go til next packet

P2P or Server, same concept

Last input is sent in packet

One hops directly halving latency

[misty wedge]

The server never rolls back in a server authoritive model

[remote crater]

If it sends the controller data of the direction you're walking

to simulate the 25 ms

Its rollback, or maybe I dont' know what you're talking about

[misty wedge]

The client rolls back, the server never does. In a p2p rollback system everyone rolls back

[remote crater]

ok yah

[misty wedge]

It's actually very different, considering p2p rollback systems need to be 100% deterministic, as they only share inputs

[remote crater]

not really,server just has a solid world

p2p kinda nebulous

[misty wedge]

You would desync if they don't simulate the same

[remote crater]

Same concept of sending the controller

Server is actually easier to code this way

[misty wedge]

Yes, definitely

[remote crater]

p2p is only marginally more difficult tho

[misty wedge]

That's why they are quite different

Desynchronization is much less of an issue if you have a server

[remote crater]

p2p's biggest failure is you need to counter hack like a crazed wildebeast

I never got a deynch when I played my private mmo in 2004-2005 with friends.

[misty wedge]

Very cool, but that doesn't really help me

[remote crater]

Sorry! Love ya man

We talking nonsense, lets get to work! HEY MON!

I'm just an idiot who likes to reinvent the wheel and code from scratch, thought I was helping by doing ABC, but they probably have a package D that does it all for you.

[misty wedge]

https://docs.unity3d.com/Packages/com.unity.netcode@1.0

[edgy fulcrum]

@remote crater are you using IConvertGameObject and stuff in 0.51? you can simply do that in GameObjectConversionSystem

how do I convert a System.Guid to Unity.Entities.Hash128?

[misty wedge]

Pass in the guid's string?

Remember to use the non-dash formatter of System.Guid though, since unity's GUIDs don't have dashes

[robust scaffold]

It begins

Does anyone actually use the search bar filter systems list?

[edgy fulcrum]

@misty wedge yeah, I had to revamp some calling code to use Hash128 everywhere 😉

[misty wedge]

What's new in V2?

[viral sonnet]

can someone give the gist for GlobalSystemVersion?

i thought GSV is incremented for every system update. this comment makes it a bit more nuanced /// <summary> /// The current change version number in this <see cref="World"/>. /// </summary> /// <remarks>The system updates the component version numbers inside any <see cref="ArchetypeChunk"/> instances /// that this system accesses with write permissions to this value.</remarks>

so my question is, what counts as write permission? the query, the component type handle read state, the access via GetNativeArray?

[tired mulch]

Is it possible to disable a component in a baking system? Because this doesn't seem to have any effect

    [WorldSystemFilter(WorldSystemFilterFlags.BakingSystem)]
    [BurstCompile]
    public partial struct InitializationAbilitySystem : ISystem
    {
        public void OnCreate(ref SystemState state)
        {
        }

        public void OnDestroy(ref SystemState state)
        {
        }

        [BurstCompile]
        public void OnUpdate(ref SystemState state)
        {
            var ecb = new EntityCommandBuffer(Allocator.Temp);
            foreach (var ability in SystemAPI.Query<AbilityAspect>())
            {
                ecb.SetComponentEnabled<Ability>(ability.Entity, false);
            }
            ecb.Playback(state.EntityManager);
            ecb.Dispose();
        }
    }

[viral sonnet]

add the options to the query .WithOptions(EntityQueryOptions.IncludePrefab | EntityQueryOptions.IncludeDisabledEntities)

and subscene needs to be closed. (might be fixed in pre15)

[tired mulch]

Alright thanks, I'll try it out

[robust scaffold]

It's the same thing, except in uitoolkit

[viral sonnet]

i get this for every subscene now [Worker0] 1 entities in the scene 'Essentials' had no SceneSection and as a result were not serialized at all.

anyone else? no idea what that's supposed to be. didn't get it in 1.0exp

and i'm not finding this damn bug that my changefilter isn't triggered... args

this is utterly frustrating right now 😄

[robust scaffold]

Yep. Just a warning though. i press clear and it doesnt do anything.

[robust scaffold]

Maybe try the journaling?

I dont think anyone uses the system search...

[viral sonnet]

good call, maybe that will help me

[viral sonnet]

haven't used it. maybe if i would have 1000 systems. but i've them ordered in groups so easy enough to find. and i'm rarely interested in systems. when i'm interested it's about the order

[robust scaffold]

Yea. Hrm. I'm gonna keep it there but not implement it yet.

[viral sonnet]

journaling is less helpful than i thought (used it for the first time) - not even the version number is reported

[viral sonnet]

hm, why am i not seeing the version in journaling? EntitiesJournaling.AddRecord( recordType: recordType, entityComponentStore: store, globalSystemVersion: version, entities: &entity, entityCount: 1, types: &typeIndex, typeCount: 1, data: recordData, dataLength: recordDataLength); it gets saved

[rotund token]

journaling is more about changes

but yeah as you point out, i did think this state was also saved

[viral sonnet]

fun with numbers 😄

so, yeah. the system version is ahead even when the version gets bumped. hm

[rotund torrent]

This is a known issue in 1.0-preview; it's called out in the physics release notes. Basically if you have non-identity scale and either physics interpolation/extrapolation on an object, the baking code tries to add PropagateLocalToWorld from two different places, and that's not allowed. We have a fix planned, but it didn't make it into the preview release. For now, the easiest workaround is to temporarily disable smoothing on these objects.

[robust scaffold]

Yea. I figured. Good to know it's being fixed.

Although now that I've disabled it, i see 0 difference between interpolated and non-interpolated graphics

[rotund torrent]

I'm not sure I understand the question; can you elaborate? ComponentLookup<T> has methods to get/set component values and to get/set whether it's enabled, both of which work from job code.

[rotund token]

I think he wants to have a query with NotEnabled

but i think None works for this

oh wait no i might be wrong with what he's saying

[rotund torrent]

Well FWIW "create a query that matches 'with + disabled' only, rather than 'with + disabled, or without'" is literally the Jira ticket I have open right now. I can't promise it'll be there for 1.0, but consider it in progress.

[robust scaffold]

More query logic is always good.

[viral sonnet]

i'm confused how that should even work. the calculate system is lagging behind in version, so when it bumps the version the combat effect system doesn't get the memo there was a change

[rotund token]

last system version is assigned on after update

what is calling increasing stack size

[viral sonnet]

in calculateSpellContainer

[rotund token]

the line below it that is debugging global version?

because it doesn't seem to have bumped it to global version which is what it should be doing

you're not doing a manual version set or something are you and using last version instead of global?

[viral sonnet]

i output the global version in the first line of update

[rotund token]

oh

4 lines above

well yeah then it's somewhat clear what is happening though i dont know why

[viral sonnet]

when i increase the stack size it gets bumped (correctly?) to the global version of calcspellcontainer

[rotund token]

wait are these logs out of order

[viral sonnet]

hm, possible. the tick is throwing me off

[rotund token]

the ordering of this is off

it's like you're missing a dependency or something

combateffectsystem is calling update spell effect?

[viral sonnet]

yes

[rotund token]

the job is updating before the version bump

[viral sonnet]

hmm

[rotund token]

just to confirm i'm reading this right

based off your log

[viral sonnet]

i should output time. tick is only 60fps. the spell container is a bit more complicated as it can get called in different stages. :/

my lack of understanding where and why global system version gets bumped is biting me 😄

[rotund token]

global system version gets bumped every system

in the pre-update

        {
            BeforeUpdateVersioning();

        internal void BeforeUpdateVersioning()
        {
            m_EntityComponentStore->IncrementGlobalSystemVersion(in m_Handle);```

the one gotcha here (which I don't really know why)
is this happens after OnStartRunning

so every system just increments globalsystemversion by 1 on update

and then in AfterOnUpdate it sets last system version to global

[viral sonnet]

i made a thread. the part i'm confused about is the very different global system version number.

[viral sonnet]

wah Loading Entity Scene failed because the entity header file couldn't be resolved. make it stop

how can this break on recompiling

any way to burstcompile this? findPathArchetype = state.EntityManager.CreateArchetype( typeof(FindPath), typeof(PathBuffer) );

[robust scaffold]

Dont use typeof

[viral sonnet]

haha yeah, but what then?

[viral sonnet]

thanks

[robust scaffold]

You can also use a NA but it wont be inline.

[robust scaffold]

_request = state.EntityManager.CreateArchetype(new NativeArray<ComponentType>(2, Allocator.Temp)
            {
                [0] = ComponentType.ReadWrite<GoInGameRequestRpc>(),
                [1] = ComponentType.ReadWrite<SendRpcCommandRequestComponent>()
            });```

[viral sonnet]

readwrite or readonly doesn't really matter here, right?

[robust scaffold]

No

[viral sonnet]

hm, now i'm already rewriting this. how would you design an archetype that's used in multiple jobs? return it from a static method?

[rotund token]

Helper struct or aspect

[viral sonnet]

so static helper method that returns the CreateArchetype and then cache it in the system?

[rotund token]

I don't use many statics like this

Usually just structs with the logic and the constructor can setup stuff

If all you're doing is wrapping a create archetype though

[robust scaffold]

I mean, just using AddComponent isnt that expensive.

[rotund token]

Static method seems fine

[rotund token]

i removed 2000 archetypes in our project from changing addcomponent to precomputing archetypes so it can make a difference!

on this size archetype though yeah

2 archetypes vs 1 isn't a huge deal

[misty wedge]

I'd like to read the component value and also set the enabled state in the same IJE. I don't think this is possible af the moment due to aliasing?

[rotund token]

you can set enabled via Handles

[misty wedge]

It won't complain of aliasing then?

[rotund token]

i think you'll have issues in IJE atm though unless you only use Lookup

[misty wedge]

Ah ok

[rotund token]

you can't pass handle + lookup without aliasing complaints

[misty wedge]

I used a component lookup and disabled safety 🤷‍♀️

[rotund token]

yeah

if you use IJC it'd be fine as well

[misty wedge]

But I'm lazy

[robust scaffold]

With SystemAPI get handles, you have no excuse.

[misty wedge]

So many letters I need to type

[rotund token]

personally my IEnableable components are only tags so kind of avoids this aliasing issue

[misty wedge]

I'm trying to write client prediction for a graph system, but I'm messing something up and some client nodes are being executed multiple times when rolling back. Do I need to check IsFirstTimeFullyPredictingTick as if I were predicting spawns?

[safe lintel]

if a component tag isnt enabled, I assume it doesnt match a query then?

[misty wedge]

Yes, it wont match unless you set the option

[robust scaffold]

my god is UI development so painful

Game view? What's that. I wish I had a 4k monitor at this point. So many windows

The UIE debugger is a godsend though.

[viral sonnet]

dock some of this stuff 😄

no 2nd monitor?

[robust scaffold]

I dont wanna go to the lab just for another monitor. Too lazy

[viral sonnet]

lol

[rotund token]

would the lab really miss a monitor 🙃

[robust scaffold]

They're really good monitors and definitely will get pissed at me walking out the door with one of them

[viral sonnet]

how are you even able to develop with just 1 monitor?

[robust scaffold]

You see that screenshot? That's what im looking at

[rotund token]

to be fair, my second monitor is just my distraction monitor 😄

it's just got tv, twitch or something on it at all time

i'd probably develop better with just 1

also discord - huge distraction

[safe lintel]

that sounds awfully familiar 😀

[viral sonnet]

discord is distracting? wait what?

[pliant pike]

glad I'm not the only one

[rotund token]

i do have an ultrawide as my primary though

which is glorious for development

i'd love to get a new, high hz one, but $

this ultrawide must have been one of the first, had it for years

no regrets on the purchase though

[viral sonnet]

what's the resolution for your ultrawide?

[rotund token]

this has been annoying me recently

[rotund token]

3440x1440

[pliant pike]

wish I could fit one on my desk

[rotund token]

i'd consider a 1600 next time (didnt exist when i bought this)

[viral sonnet]

uh, nice 😄

[rotund token]

i on the other hand, so much unity space

[viral sonnet]

1st world problems

[rotund token]

it's so good. i would definitely take an ultrawide over 2 monitors these days

[rotund torrent]

Note sure if this is common knowledge or not, but FWIW archetypes are already cached internally, so if you request the exact same set of types from two systems, you're already only paying to create it once.

[viral sonnet]

would you say we can ignore system based caching because of this?

[rotund torrent]

Archetypes are automatically cached per-World, not per-system.

[viral sonnet]

ok, i mean, i have like 3 different systems where the same archetypes is used in a job so i cache the archetype in the systems

[robust scaffold]

There's a 4k monitor in one of the rooms over at the lab. I hooked my laptop to it and the screen was so big and the text so tiny i felt like I was hunting for grains of sand on a screen.

[rotund torrent]

If you want to be absolutely certain that multiple systems are using the exact same archetype, then it would make sense to create it once and cache the archetype handle somewhere for them all to share. But in general there's no need to aggressively de-duplicate archetype creation

[rotund token]

i personally think ultrawide is better than 4k for development

[viral sonnet]

yeah i think 4k is cool for tvs or gaming but not great for development. everything's too small

[rotund token]

i also find the extra horizontal space more useful than vertical

but we have devs who like their 4k so to each their own

other people can be wrong 😄 ultrawide superior

[viral sonnet]

friend of mine was a very early adopter of 4k and he lost his mouse constantly until he used mightymouse or whatever that tool is called to make it big and shiny

now that was fun playing lol with him

yeah agreed, horizontal screen space is much more useful

artists like their 4k monitors a lot from what i know

[robust scaffold]

I think for artists, it's more pixel density than size

[viral sonnet]

yep, which makes a lot of sense

[robust scaffold]

The one in the lab is giant. I thought it was a flat screen for a second until I walked by someone hooked up a scintillator display to it.

[pliant pike]

its crazy we still havent got proper scaling and resolution agnostic software on windows

[viral sonnet]

now i think where we can all agree, curved monitors are trash

[pliant pike]

definitely I despise them and don't understand how anyone uses them

[robust scaffold]

I will only accept curved monitors if it was 360

[rotund token]

my ultrawide is curved

it's very slight curve, you don't notice it

but when compared side by side to a flat ultrawide at same resolution

i actually prefer the subtle curve

[gusty comet]

my ultrawide is curved too - I worked with a flat ultrawide for a while, but there was a slight colour distortion at the edges that bothered me

[safe lintel]

i dont like 4k but then again my eyesight kinda sucks and unless its a mac windows dpi scaling still has issues with some programs

[rotund token]

yeah this

[viral sonnet]

yeah MS isn't really known for innovation outside of annoying users with unnecessary changes and "telemetry" - mac rendering is so much better

[robust scaffold]

There's plenty of innovation. it just shows up every other windows release cycle.

[gusty comet]

i think mac benefits from a limited hardware set they are developing against - MS has to develop against very wide hardware bases

[rotund token]

{
    fixed (SystemState* state = &systemState)
    {
        this.systemState = state;
    }

c# question, is there a nicer way to get the pointer to a systemstate ref?

UnsafeUtility.AddressOf doesn't work since SystemState is a ref struct

[viral sonnet]

hm, so the curve helps with color distortion? i've honestly not taken this into account. never had an issue with that on my flat monitors

[rotund token]

are they ultrawide though? there's a reason most high end ultrawide have a slight curve while cheap ones are flat

[viral sonnet]

no, not ultrawide 🙂

[gusty comet]

curve means the angle between your eyes, and the plane of the screen is less therefore lower chance of colour distortion

[pliant pike]

I'm more concerned about the problem of straight lines being distorted, and how it effects things like 3d modelling and sculpting

[rotund token]

i think 4k is better for artists

i just think the ultrawide format is great for coding/unity work

[gusty comet]

quick DOTS question - does anyone use the GameObject -> ECS conversion as their way of doing DOTS dev? or are you all developing components / systems from scratch? The whole GO -> ECS feels a bit... icky to me

[harsh marsh]

Alienware 34” 1800R is great

[rotund token]

i would say most people use subscene/baking

[harsh marsh]

If you sit so close to a big screen the curve makes sense

[robust scaffold]

We're all doing GO -> Entities baker. It's pretty straightforward once you get the hang of it.

[rotund token]

don't think of it as GO -> Entities
think of it as Authoring -> Runtime data

[pliant pike]

one of my projects I just use pooled game objects directly in Systems

there's lots of different ways to do things

[gusty comet]

hits me a bit weird to architect with OOP in mind, and then run it through a conversion process to reach a DOD structure

but hey.. if it works, it works right?

[robust scaffold]

Well no, you want to structure your GOs in a DOD format as well.

[pliant pike]

there's a vid posted on Unity recently about similar https://www.youtube.com/watch?v=RhU8NZtgYp0&t=944s&ab_channel=Unity

[gusty comet]

thanks, i'll watch it tomorrow whilst i'm... 'working'

[rotund token]

no solution? 😦 oh well ugly code

[proud jackal]

We used to do exactly this internally, ironically how SystemAPI came about, so i don't think there's better syntax.

[rotund token]

thanks for confirming

not a huge deal, just wasn't sure i was missing something in c#

[viral sonnet]

why is my asset import logs getting spammed with hundreds of the above? I think it's triggering a SIGSEGV somewhere in the end of building addressables 😦

[rotund token]

update to pre 15

this issue is significantly reduced

a variation still happens on occasions but it's a lot rarer

[edgy fulcrum]

im using 2022.2.0b16, I dont see it in the pkg window?

[rotund token]

no idea, i believe it should appear.

you can update to 2022.2.0f1 as well if you want

but just add it manually then if it's not appearing for you

[edgy fulcrum]

yeah thats a good hack there, lemme try that

[rotund token]

been out for like a week?

[edgy fulcrum]

yeah roomies moved in, been a hectic time 😉

[rotund token]

there is still at least 1 failure in subscenes

but yeah i only get it ever few hours on general instead of every recompile

so it's much more usable

[edgy fulcrum]

yeah im hoping with every update I get less wonky errors in figuring out how to load prefabs as subscenes 🙂

[rotund token]

byte* ptr = null;
var source = ptr + (i * size);

this won't cause issues as long as i don't actually use source right

i'm assuming this simplifies down to basically var source = 0x00.. + (i * size);
(Kind of just rubber ducking the channel ^_^" serialization is confusing)

[coarse turtle]

yea

[hot basin]

are managed components still a thing?

can't fing any info how use them with bakeing

[late mural]

wondering, is there a Unity.Mathematics version of Mathf.PerlinNoise?

[void ravine]

not sure what noise version is a match for PerlinNoise but all noise functions of that package are here
https://docs.unity3d.com/Packages/com.unity.mathematics@1.0/api/Unity.Mathematics.noise.html

[late mural]

thanks a ton!

perhaps pnoise is perlin noise? (is there a wiki for unity mathematics btw?)

edit: it seems that actually cnoise may be perlin noise, according to some random forum posts atleast

[safe lintel]

@hot basin yeah AddComponentObject and AddSharedComponentManaged exists in bakers

[misty wedge]

Is the tick where an InputEvent is sent not guaranteed to also have the other values set correctly when the server receives it?

[hot basin]

thanks!

and anyone know how skinned mesh works? I'm looking at the sample and it seems complex

[misty wedge]

This is really weird, even if I write the server tick in the command, while the server tick matches on the server, the data is not set, but the input event is set...

Seems kind of pointless to automate the handling of one off events if you can't send any additional data with those events..

[rotund token]

are you talking about netcode?

[misty wedge]

Yeah

[rotund token]

what do you mean by inputevent?

(is that an actual component or yours)

[misty wedge]

No, it's part of netcode

https://docs.unity3d.com/Packages/com.unity.netcode@1.0/api/Unity.NetCode.InputEvent.html?q=InputEvent

It automatically handles one off event execution on the server

[rotund token]

ah i haven't really used it since 0.51

[misty wedge]

Yeah I'm in the process of migrating some stuff to the new stuff, but this is behaving very strangely

[rotund token]

is this not just designed to fix the bool jump problem

people often run into

[misty wedge]

No idea

This is my command component

And if I set UseAbility on the client, and set the UsedAbility to a value in the same frame, while UseAbility is set on the server on the same tick, the UsedAbility is invalid

^ client code

Not sure if this is a bug, unsupported behaviour, or if I'm doing something wrong

But it seems odd that you can't send some kind of payload for your one off event

It's also random, sometimes the data will be there, sometimes it won't

[rotund token]

i lost interest with netcode when my changefilter support broke
(and the work flow for no-prediction physics is now problematic)

and i'm waiting till it's fixed again so yeah haven't kept up with 1.0

[misty wedge]

What's problematic when not using physics?

[rotund token]

well they have a predicted physics world right

and non-predicted or client stuff must exist in a second world now

[misty wedge]

Ah, you meant you want to use physics but not have it be predicted

[rotund token]

but my netcode project has no predicted ghosts

and it used to work really nice but now i basically have to double simulate physics for no reason

to get it to work with client only physics objects

i know how to fix or workaround it, i just cbf atm

no change filters significantly wrecked my client performance anyway

[misty wedge]

I don't think I've ever used a change filter

[robust scaffold]

They're great

[misty wedge]

But I'm assuming i'd need to actually write my code so that they make sense, since otherwise my chunks would change each frame anyways

[rotund token]

yes it's kind of the problem imo

you can't just add them later
