@shut hare yup

#

Your missing the add job handle bit

#

Would be amazing if unity could make that more automatic

#

System.AddJobHandleForProducer

#

After your foreach

#

Pass in Dependancy

#

But also your using run, you don't need a ecb. Is that cause your testing?

#

@shut hare here's the docs, the last line in the sample is what your missing

https://docs.unity3d.com/Packages/com.unity.entities@0.17/manual/entity_command_buffer.html

shut hare Mar 21, 2021, 9:20 AM

#

I'm just trying to figure things out man 😄

ocean tundra Mar 21, 2021, 9:20 AM

#

Yea I get that

shut hare Mar 21, 2021, 9:22 AM

#

oh i see, i wanted to start without the multithreaded bits it feels easier i thought this line was for the jobs workflow

ocean tundra Mar 21, 2021, 9:22 AM

#

Ecbs is for jobs

#

But even single threaded they are faster

#

As unity can group all your changes into one big execute

shut hare Mar 21, 2021, 9:24 AM

#

Sadly it doesn't seems to work 😦

        protected override void OnUpdate()
        {
            var ecb = system.CreateCommandBuffer();

            Entities.ForEach((Entity entity, in DespawningEntity despawningEntity) =>
            {
                ecb.DestroyEntity(entity);

            }).Run();

            system.AddJobHandleForProducer(Dependency);
        }

ocean tundra Mar 21, 2021, 9:26 AM

#

It should

#

Maybe just change run to schedule

#

Are you sure your creating that system?

shut hare Mar 21, 2021, 9:28 AM

#

I'll try that, yeah like this

destroyDespawningSystem = ECSWorld.CreateSystem<DestroyDespawningSystem>();

ocean tundra Mar 21, 2021, 9:29 AM

#

That's not quite enough to get that system running

#

You'll also need to add the system into a update group

#

Sorry can't help more, g2g. Good luck

shut hare Mar 21, 2021, 9:30 AM

#

np man thx

dark cypress Mar 21, 2021, 5:31 PM

#

Is there a way to modify the prefab entities?

#

I want to initialize some data on startup.

#

I must use a system and not the conversion pipeline, because I need many systems to do their own initialization based on what component there is on the prefab.

pliant pike Mar 21, 2021, 5:40 PM

#

you could convert the data so it's easier to modify

dark cypress Mar 21, 2021, 5:40 PM

#

Figured it out. .WithEntityQueryOptions(EntityQueryOptions.IncludePrefab)

pulsar jay Mar 22, 2021, 10:50 AM

#

How can I write to a native queue from multiple threads? As far as I have seen I cannot use AsParallelWriter again when another system is already using a parallelWriter. So I cached the parallelWriter and even added manual dependencies to the systems so that the reader depends on all the writers and completes the combined writer handles before reading. But I still get this error: "The previously scheduled job HitVFXSystem:OnUpdate_LambdaJob0 writes to the Unity.Collections.NativeQueue"

pliant pike Mar 22, 2021, 1:12 PM

#

I don't think it's possible with a nativequeue

pulsar jay Mar 22, 2021, 1:16 PM

#

pliant pike I don't think it's possible with a nativequeue

From what I have found so far that seems to be the case. If I understand correctly the NativeQueue can be written in parallel from a single job and not multiple jobs. I suppose this is due to the necessity for the writing order to be deterministic?!

#

What I am trying to do is basically building a custom command buffer to spawn pooled VFX effects. It would be great if it was possible to just extend the ECB. Or maybe NativeStream will work for that usecase?

pliant pike Mar 22, 2021, 1:21 PM

#

why would you want to extend the ecb, do you mean you want to extend its length of running time?

pulsar jay Mar 22, 2021, 1:22 PM

#

No I am trying to have custom commands

#

You could also call it command or message queue

#

Like this example from the UnityFPS but with entities und jobs: https://github1s.com/Unity-Technologies/FPSSample/blob/6b8b27aca3690de9e46ca3fe5780af4f0eff5faa/Assets/Scripts/Game/Modules/Effect/VFXSystem.cs

#

In this case they just use a Dictionary but its obviously neither threadsafe nor burstable

#

Found a thread where somone is using a similar system to queue audio messages: https://forum.unity.com/threads/event-system.779711/page-4#post-6743209

Unity Forum

Event System

Looks cool overall, but manual dependency management kinda looks clunky. (Need to use more to adjust)
Also, would like to see more samples / examples...

#

but this does not work as soon as more than one job is writing to the NativeQueue

pliant pike Mar 22, 2021, 1:27 PM

#

yeah I haven't really looked into this stuff yet sorry

pulsar jay Mar 22, 2021, 1:28 PM

#

Ok thanks anyway 🙂

pliant pike Mar 22, 2021, 1:39 PM

#

are there any data types that allow you to write to a single list in multiple jobs 🤔

#

that would just be unsafe and result in race conditions surely

pulsar jay Mar 22, 2021, 1:39 PM

#

Thats what I am currently trying to figure out

#

I think NativeStream might work

#

Thats why I was also looking at extending ECBs as they basically are lists that can be written from multiple jobs

#

Internaly the ECB Systems use a NativeList<EntityCommandBuffer>

#

so its basically a List of lists

pliant pike Mar 22, 2021, 1:43 PM

#

interesting, I guess an ecb is just queuing up commands so its not likely to conflict

pulsar jay Mar 22, 2021, 1:44 PM

#

yeah since each writer creates its own unique list there should not be a problem

pliant pike Mar 22, 2021, 1:45 PM

#

can't you do that yourself create a list in multiple jobs then add them all together at the end

pulsar jay Mar 22, 2021, 1:46 PM

#

I am currently trying to figure out if this works

#

but if I remember correctly it is not possible to nest native collections

#

yeah I remembered correctly 😬 "Unity.Collections.NativeQueue`1[VFXSystem+VFXCommand] used in native collection is not blittable, not primitive, or contains a type tagged as NativeContainer"

bright sentinel Mar 22, 2021, 3:04 PM

#

pulsar jay so its basically a List of lists

Couldn't you use the same pattern? A list of NativeQueue?

pulsar jay Mar 22, 2021, 3:04 PM

#

bright sentinel Couldn't you use the same pattern? A list of NativeQueue?

Thats exactly what I tried leading to the error above your message

bright sentinel Mar 22, 2021, 3:04 PM

#

Oh

pulsar jay Mar 22, 2021, 3:05 PM

#

you cannot nest native collections

bright sentinel Mar 22, 2021, 3:05 PM

#

or contains a type tagged as NativeContainer

#

?

#

Seems like it should work

pulsar jay Mar 22, 2021, 3:05 PM

#

it works for ECBs as they use some pointer vodoo and are not declared as native containers by unity

bright sentinel Mar 22, 2021, 3:05 PM

#

Oh, sorry I read that inversely

#

Maybe you can use UnsafeList?

#

Or FixedList?

pulsar jay Mar 22, 2021, 3:07 PM

#

well I have to see if these are nestable

north bay Mar 22, 2021, 3:07 PM

#

pulsar jay it works for ECBs as they use some pointer vodoo and are not declared as native ...

Unity just uses a managed list to hold ECBs inside the EntityCommandBufferSystem

bright sentinel Mar 22, 2021, 3:07 PM

#

Oh yeah lol

north bay Mar 22, 2021, 3:07 PM

#

Idk how they are going to solve that for ISystembase

#

Probably do some pointer vodoo lol

bright sentinel Mar 22, 2021, 3:07 PM

#

Or maybe not all systems will use ISystemBase?

pulsar jay Mar 22, 2021, 3:08 PM

#

north bay Unity just uses a managed list to hold ECBs inside the EntityCommandBufferSystem

They use NativeList<EntityCommandBuffer>

north bay Mar 22, 2021, 3:08 PM

#

Huh

#

When did they change that

pulsar jay Mar 22, 2021, 3:08 PM

#

but a EntityCommandBuffer is allowed to be in a NativeList a NativeQueue is not allowed

#

maybe because they made ecbs burstable?

north bay Mar 22, 2021, 3:08 PM

#

Does the entity command buffer not hold a dispose sentinel anymore?

bright sentinel Mar 22, 2021, 3:08 PM

#

But couldn't you just use a List<NativeQueue> instead?

pulsar jay Mar 22, 2021, 3:09 PM

#

bright sentinel But couldn't you just use a List<NativeQueue> instead?

Well thats so simple it might actually work 😅

bright sentinel Mar 22, 2021, 3:09 PM

#

When working with DOTS I also tend to forget managed stuff 😂

hollow sorrel Mar 22, 2021, 3:11 PM

#

dunno why we still cannot nest nativecontainers

#

other than safety system

#

just because we can shoot ourselves in the foot doesn't mean unity shouldn't let us

north bay Mar 22, 2021, 3:11 PM

#

Ohhh

            m_PendingBuffers = new List<EntityCommandBuffer>();
#else
            m_PendingBuffers = new NativeList<EntityCommandBuffer>(Allocator.Persistent);
#endif```

north bay Mar 22, 2021, 3:11 PM

#

hollow sorrel just because we can shoot ourselves in the foot doesn't mean unity shouldn't let...

Cuz leak detection

#

🤷‍♂️

bright sentinel Mar 22, 2021, 3:11 PM

#

@hollow sorrel Well you can always disable the safety system

#

So they DO let you

hollow sorrel Mar 22, 2021, 3:11 PM

#

yea but that's what i mean

#

if we already can disable that

#

why not allow nesting containers

north bay Mar 22, 2021, 3:12 PM

#

They need to figure out how to get unmanaged leak detection working

#

Tbh

bright sentinel Mar 22, 2021, 3:13 PM

#

Oh wait so you mean even when safety is disabled you still can't do it?

north bay Mar 22, 2021, 3:15 PM

#

I think you can, but that gets rid of all safety checks

stone osprey Mar 22, 2021, 6:08 PM

#

I need some quick help... I receive a packet from my server and i implemented some sort of serializer which converts the packet to a struct. I tried to add that deserialized packet via "manager.AddComponent(entity, deserializedPacket)"... Yeah... it tells me that generic types need to be known during compile time. My deserialized component is not generic... i just dont use the <> when adding that because i dont know what type the deserialized packet is. What should i do now ?

#

How can i add a component without "<>" to an entity ?

pulsar jay Mar 22, 2021, 6:12 PM

#

stone osprey How can i add a component without "<>" to an entity ?

Thats tough because ECS needs the type in order to add the component. Maybe you could look into the internal type index. AFAIK ecs creates an id for each type. So maybe you could send this typeID with your package and use it to add the component

#

Do you convert it to a specific type of struct? Or is the deserialized data an object?

stone osprey Mar 22, 2021, 6:13 PM

#

Well of course i know the type... by "myDeserializedPacketComponent.getType()"... but i cant use the generics because i dont know what type it will receive ^^ And i also dont wanna write a huge switch statement.

#

Packet -> Deserialising -> MyComponent : IcomponentData{} -> Add to entity | Thats the current flow...

pulsar jay Mar 22, 2021, 6:14 PM

#

Maybe AddComponent(Entity entity, ComponentType componentType) will help?

#

you can create an componentType from a Type

stone osprey Mar 22, 2021, 6:15 PM

#

Ok this is getting interessting 😄 And how ?

coarse turtle Mar 22, 2021, 6:16 PM

#

hmm why not just parse the data as bytes into their desired struct types? 🤔

#

ofc that assumes you have a schema for the bytes

pulsar jay Mar 22, 2021, 6:16 PM

#

stone osprey Ok this is getting interessting 😄 And how ?

public static ComponentType ReadWrite(Type type)

stone osprey Mar 22, 2021, 6:17 PM

#

Thanks im gonna try that out ! hopefully i dont run into the same issue when i wanna update them next ^^

safe lintel Mar 22, 2021, 6:18 PM

#

man i went down that rabbit hole, got around it using dynamic types and reflection, so I don't think it works out as a performant solution(but my needs were just a runtime editor)

ocean tundra Mar 22, 2021, 7:08 PM

#

Yea I too have fought with ECS and dynamic loading of types
Was a massive pain 😛

#

@stone osprey For my networking, the first thing i send is the type id, i then have a massive switch statement which creates the exact struct and loads data into it, then attaches to entities as needed

#

So nothings dynamic/reflection based

#

and i use code gen to create that switch statement 😛

pulsar jay Mar 22, 2021, 7:10 PM

#

ocean tundra and i use code gen to create that switch statement 😛

But doesnt "AddComponent(Entity entity, ComponentType componentType)" work for you?

#

or the one that takes the typeId

ocean tundra Mar 22, 2021, 7:11 PM

#

it didnt as i was boxing all my structs into a common interface

#

and interfaces are not sturcts

#

or something like that 😛

pulsar jay Mar 22, 2021, 7:12 PM

#

ok I see

ocean tundra Mar 22, 2021, 7:12 PM

#

i was adding components that had fields too

#

not empty tags

#

honestly was super annoying

stone osprey Mar 22, 2021, 7:15 PM

#

Thanks everyone... i think "AddCOmponent(entity, type)" did the trick... atleast i dont get errors anymore ^^

#

Right after that i trigger a SetComponent(entity, struct) which works fine without knowing the generic type

ocean tundra Mar 22, 2021, 7:17 PM

#

i never actually tried that combo... i was too focused trying to get AddComponentData working so its a single opperation

stone osprey Mar 22, 2021, 7:17 PM

#

wait... or probably it does not work fine at all

ocean tundra Mar 22, 2021, 7:17 PM

#

:/

stone osprey Mar 22, 2021, 7:18 PM

#

The typical showcase effect... i run it again and i get weird errors... one moment

ocean tundra Mar 22, 2021, 7:19 PM

#

my other requirement was to use jobs and burst, so again that would be why i landed on the switch statement

stone osprey Mar 22, 2021, 7:21 PM

#

Fuckkk... "SetComponent(entity, struct)" does not workkkkk... the same exceptionnnn as i would have used the "AddComponent" without generics

#

Any other ideas ? I clearly dont wanna have a huge switch statement here xD thats too much pain

north bay Mar 22, 2021, 7:29 PM

#

What exception do you get? Is your struct boxed?

#

There is an internal method called SetComponentDataRaw if you can modify the package source

stone osprey Mar 22, 2021, 7:32 PM

#

"All Component Type must be known during Compile time"

#

Im using .SetComponent(entity, data) from an command buffer

north bay Mar 22, 2021, 7:38 PM

#

What is data in this case, an interface?

stone osprey Mar 22, 2021, 7:40 PM

#

Just an object... for example a HealthComponent or any other component...

#

So basically everything that extends IComponentData

#

#

#

Just imagine that i dont know the type, thats why i use IComponentData... that picture was just a test if it works or not.

north bay Mar 22, 2021, 7:53 PM

#

Ehh idk about entityCommandBuffer but you could do something like that when you use the EntityManager and make SetComponentDataRaw public:

ocean tundra Mar 22, 2021, 7:54 PM

#

stone osprey "All Component Type must be known during Compile time"

Yea that was the error i got

north bay Mar 22, 2021, 7:54 PM

#

I didn't test that tho so there might be something I'm missing

ocean tundra Mar 22, 2021, 7:54 PM

#

hence the massive super switch 😛

stone osprey Mar 22, 2021, 7:55 PM

#

@north bay Thanks, i think that it works fine when i use the entitymanager instead... but i really, really hoped that theres some way to get it working with the CommandBuffers... because it would be perfect for networking :/

ocean tundra Mar 22, 2021, 7:55 PM

#

ill be happy to share my code gen bits

stone osprey Mar 22, 2021, 8:01 PM

#

Thanks... but im really searching for a cleaner way ^^

#

Is there any performance impact when we call "EntityManager.SetComponentData()" on the main thread ? Im just using an ECB here because i was told it has better performance

sturdy rune Mar 22, 2021, 8:03 PM

#

Well did you register the generic components?

stone osprey Mar 22, 2021, 8:05 PM

#

@sturdy rune Its not even generic... Look at the second pic above ^^ "new Identity()" is not generic. But im casting it to an interface, because i dont know the type during runtime. So i basically try to call .SetComponentData<...>() without knowing the generics. Thats what is breaking my neck right now

sturdy rune Mar 22, 2021, 8:07 PM

#

Ah got it. Forgive my naivete but why do you not know components vs components associated with a system

stone osprey Mar 22, 2021, 8:08 PM

#

@sturdy rune Long story, but i basically receive them as packets from a server and need to attach them to the entities.

#

Thats why i dont know their generic type

#

And i dont wanna have a huge switch statement there

sturdy rune Mar 22, 2021, 8:11 PM

#

Yea I could understand why haha. I would have thought the components would be known on both sides anyway, and you would receive a generic component that indicates what type of component needs to be added i.e. you've serialized the message and now need to deaerialize - why go straight to adding component? Are you that concerned with performance or is there a real reason

#

But I guess there is your problem you don't want a huge deserializing switch

#

Lol

stone osprey Mar 22, 2021, 8:12 PM

#

The server uses a different language... java... thats why i deserialize them and dont know their generic type. Just lets say theres no other way ok ? ^^ I dont wanna lose the focus on the main problem. I have some object and i know it extends IComponentData and i wanna attach it to an entity. How do i do that without generics ?

#

I see... this is only achieveable by using reflection... damn, i really hope that unity adds such features some day. Every ECS i know supports this

frosty siren Mar 22, 2021, 8:31 PM

#

stone osprey The server uses a different language... java... thats why i deserialize them and...

If i understand you correctly, if you need to add arbitrary IComponentData object then you can have it as IConvertGameObjectToEntity on a separate gameobject. Then you can manually grab this gameobject and entity you want and use convertion utility on them. That way you can build some "Component prefabs" and inject it at runtime. But it is not efficient.
But there is no way to get IComponentData types that entity has on itself at runtime. And i want this feature from i know DOTS.

stone osprey Mar 22, 2021, 8:32 PM

#

@frosty siren Thanks... but thats not the problem here. I receive plain data from the server which i need to attach on an entity without knowing its generic type at compile time.

#

I cant convert anything... because i only receive plain structs from the server

#

And i need to attach them to an entity without <>...

frosty siren Mar 22, 2021, 8:32 PM

#

oh, ok, i see

north bay Mar 22, 2021, 8:33 PM

#

I don't think you can do that without modifying package source

frosty siren Mar 22, 2021, 8:36 PM

#

all i can imagine is have some mapping that will match value from server and IComponentData type that need to add. But there is no way to get values.

stone osprey Mar 22, 2021, 8:36 PM

#

That would work... but its very inflexible and if theres one think i hate then its hard coded stuff.... i think the best bet is to go with reflection, even if its much slower

frosty siren Mar 22, 2021, 8:37 PM

#

you can avoid inflexibility by using a little bit of codegen 😄

north bay Mar 22, 2021, 8:37 PM

#

Your deserialized component is boxed as an IComponentData interface right?

ocean tundra Mar 22, 2021, 8:38 PM

#

mmm yes code gen 😛

north bay Mar 22, 2021, 8:38 PM

#

Make sure to pin it before you pass it to your reflection method

frosty siren Mar 22, 2021, 8:38 PM

#

yummi

ocean tundra Mar 22, 2021, 8:38 PM

#

this is the templating tool i use

#

https://github.com/scriban/scriban

#

but what i really want is source generators

stone osprey Mar 22, 2021, 8:39 PM

#

In fact its pretty easy... the last method inside that method is what i need

ocean tundra Mar 22, 2021, 8:39 PM

#

will make it all so much better

stone osprey Mar 22, 2021, 8:39 PM

#

BUT OFCOURSE ITS PRIVATE

#

WHY THE HECK IS EVERYTHING PRIVATE, PROTECTED OR INTERNAL ?

ocean tundra Mar 22, 2021, 8:39 PM

#

haha

#

yea i know

#

sooo annoying

stone osprey Mar 22, 2021, 8:39 PM

#

I bet they don trust us to use them properly

ocean tundra Mar 22, 2021, 8:39 PM

#

i think they only public stuff they are 100% sure is good for us to use

#

as in default high performance

#

and highly tested

safe lintel Mar 22, 2021, 8:40 PM

#

dots made basic game stuff so easy to avoid spaghetti code but when i need to use more advanced things that are internal or private, my code turns into spaghetti again 🥲

stone osprey Mar 22, 2021, 8:40 PM

#

i hate unity for that mantra

ocean tundra Mar 22, 2021, 8:40 PM

#

yup

frosty siren Mar 22, 2021, 8:40 PM

#

stone osprey WHY THE HECK IS EVERYTHING PRIVATE, PROTECTED OR INTERNAL ?

i understand your pain, mate

ocean tundra Mar 22, 2021, 8:41 PM

#

they should do what that scriban templating tool did
they have a optional define that changes things from internal to public

#

sooo good

#

if unity added that, then us crazys who want the internal private stuff could just add that define

frosty siren Mar 22, 2021, 8:42 PM

#

i tried to fix Companion stuff's performance and i have finished with 1900 new files in project because there is no way for me instead of cache package and edit Unity.Entities package BECAUSE all is private

ocean tundra Mar 22, 2021, 8:43 PM

#

yea im trying to stay far away from editing unitys packages

#

also i have no clue how to maintain those changes

frosty siren Mar 22, 2021, 8:44 PM

#

but the real good thing is that it so simple to read code now

ocean tundra Mar 22, 2021, 8:44 PM

#

like when theres a update, how do you bring in unitys update without losing all your stuff

frosty siren Mar 22, 2021, 8:44 PM

#

ocean tundra also i have no clue how to maintain those changes

remember, backup, and paste after every update if need

safe lintel Mar 22, 2021, 8:44 PM

#

was that by chjance the companion gameobject transform gc allocations?

ocean tundra Mar 22, 2021, 8:45 PM

#

frosty siren remember, backup, and paste after every update if need

there must be better ways then copy pasting things :/ i keep thinking git must have something, but no idea how to do it

frosty siren Mar 22, 2021, 8:45 PM

safe lintel was that by chjance the companion gameobject transform gc allocations?

not only this, but yes

safe lintel Mar 22, 2021, 8:46 PM

how complex a fix was it? i think i remember seeing something on the forums but cant find it now

frosty siren Mar 22, 2021, 8:46 PM

mmm, few lines of code

hope they exist

frosty siren Mar 22, 2021, 8:48 PM

#

safe lintel how complex a fix was it? i think i remember seeing something on the forums but ...

The real problem is that system updates ALL entities with companion components and you can't exclude entity. So i have changed query a little bit.

#

Tried to use CopyTransformToGameObject system which is far more optimal but it produces a really weird results (i have described it in last reply https://forum.unity.com/threads/ijobparallelfortransforms-wrong-indexes.1078088/)

stone osprey Mar 22, 2021, 8:57 PM

#

Quick question... whats an managed component ?

ocean tundra Mar 22, 2021, 8:57 PM

#

a class instead of a sturct

stone osprey Mar 22, 2021, 8:57 PM

#

class ?

#

Ahh ok

#

thanks

ocean tundra Mar 22, 2021, 8:57 PM

#

but you lose out on all the cool stuff

#

so dont use them :p

#

no burst/jobs

frosty siren Mar 22, 2021, 8:58 PM

#

(use them if you want to develop a game 👍 )

ocean tundra Mar 22, 2021, 8:58 PM

#

😛

#

yea im too harsh on them

#

i have to use some for my networking, as i store the connection stuff in one, and somewhere inside that is a unity safty check thing, which prevents use inside a struct IComponent

gusty comet Mar 22, 2021, 8:59 PM

mmm instant noodles

stone osprey Mar 22, 2021, 9:04 PM

#

Is there any way to acess "SetComponentDataRaw()" ?

#

Or does this also require reflection ? It tells me its internal :c

ocean tundra Mar 22, 2021, 9:05 PM

#

edit it to public?

stone osprey Mar 22, 2021, 9:05 PM

#

xD

#

My hate grows...

ocean tundra Mar 22, 2021, 9:05 PM

#

yup

#

is the class partial at all?

safe lintel Mar 22, 2021, 9:05 PM

#

actually you could try the InternalsVisibleTo thing

ocean tundra Mar 22, 2021, 9:05 PM

#

ive discovered a nice way of extending things via partial

safe lintel Mar 22, 2021, 9:06 PM

#

I used a ton of reflection to get access to that stuff but that was before I knew that and havent yet refactored

stone osprey Mar 22, 2021, 9:06 PM

#

Its like... Oh you wanna use the ECS ? Of course... but only in MY WAYYYYYYY angry unity noises

#

@safe lintel InternalsVisible to ?

#

Never heard of that... whats that ?

ocean tundra Mar 22, 2021, 9:07 PM

#

dont you need to use that inside the Entities package tho?

frosty siren Mar 22, 2021, 9:07 PM

ocean tundra Mar 22, 2021, 9:07 PM

#

@stone osprey ooo just checked, entity manager is partial

safe lintel Mar 22, 2021, 9:07 PM

#

tertle's post explains it in more detail with an example

ocean tundra Mar 22, 2021, 9:08 PM

#

so you can nicely extend it,
Make a new folder in your project
Put a asmref in their pointing at Entities
then create a cs file, and give it the same namespace as EntityManager
finally give the class the same signiture as EntityManager

#

inside your new class you can make public methods 'wrapping' the internal/private ones from Unity

#

boom, nicely exposed unitys internal stuff without directly editing their package

stone osprey Mar 22, 2021, 9:09 PM

#

Bless the lord ! Thanks im gonna try that out ^^

#

No more reflection wuuuu

#

party

ocean tundra Mar 22, 2021, 9:10 PM

#

😛

#

let me know how it goes

#

ive just started doing it for some of my stuff which im building into packages

#

but havnt tested on unitys stuff yet

stone osprey Mar 22, 2021, 9:13 PM

#

@ocean tundra Hmmm... ok first problem 😄 Whats an ASMRef ? xD And where do i create one ?

ocean tundra Mar 22, 2021, 9:13 PM

#

in the create menu

stone osprey Mar 22, 2021, 9:14 PM

#

Ah the definition file ?

ocean tundra Mar 22, 2021, 9:14 PM

#

not a asmdef

#

😛

#

a asmref

#

https://docs.unity3d.com/Manual/class-AssemblyDefinitionReferenceImporter.html

stone osprey Mar 22, 2021, 9:15 PM

#

Ah in unity ^^ found it, thanks

ocean tundra Mar 22, 2021, 9:15 PM

#

yea sorry, should have been more clear

stone osprey Mar 22, 2021, 9:20 PM

#

@ocean tundra Thanks, so that worked so far ^^ the only problem is... my partial class cant find ANY of the internal methods from the EntityManager

ocean tundra Mar 22, 2021, 9:20 PM

#

oh

#

um

#

are you sure you have the right namespace and class name?

stone osprey Mar 22, 2021, 9:20 PM

#

ocean tundra Mar 22, 2021, 9:20 PM

#

close and reopen editor?

#

and see what unity says

#

asmref is a unity thing, not normal code, so your editor might be unhappy

#

i think it kinda worked tho, your partial EntityManager has a ton of references/usages

#

what code editor are you using?

hollow sorrel Mar 22, 2021, 9:24 PM

#

if it's private then only works if it's in same assembly

ocean tundra Mar 22, 2021, 9:24 PM

#

but thats what the asmref is for

#

adds your files to the targeted assembly

hollow sorrel Mar 22, 2021, 9:24 PM

#

ah

stone osprey Mar 22, 2021, 9:25 PM

#

So... first of all, it doesnt like the Equatable stuff

#

Tells me that its already implemented

ocean tundra Mar 22, 2021, 9:25 PM

#

oh maybe your not ment to copy interfaces

#

just rereading this

#

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/partial-classes-and-methods

Partial Classes and Methods - C# Programming Guide

Partial classes and methods in C# split the definition of a class, a struct, an interface, or a method over two or more source files.

stone osprey Mar 22, 2021, 9:26 PM

#

second... it somehow does not find ANY other methods from that class

#

#

Only those i wrote

ocean tundra Mar 22, 2021, 9:26 PM

#


    XML comments

    interfaces

    generic-type parameter attributes

    class attributes

    members

#

yea so that would be copied, so dont need the interfaces

#

What does unity say if you ignore your code editor?

#

im thinking your code editor dosnt understand asmref, so it cant merge your files

#

i use Rider and it was confused untill i cleared my caches

stone osprey Mar 22, 2021, 9:28 PM

#

Another funny side effect is this... Somehow it tells me that theres stuff missing 😄

#

Unity is fine... well it shows me all those errors now.

#

Like that Entitymanager has no world anymore

ocean tundra Mar 22, 2021, 9:29 PM

#

oh it definitly hasnt merged then

#

instead its replaced using your type

stone osprey Mar 22, 2021, 9:29 PM

#

Yeah :/

#

Hmmm

ocean tundra Mar 22, 2021, 9:29 PM

#

sorry ill give it a try shortly

#

worked fine for my package and type

#

maybe the folder structure matters?

stone osprey Mar 22, 2021, 9:31 PM

#

@ocean tundra Not sure... im using rider, this is the current structure ^^

#

All those red underlined stuff only due to the entitymanager error xD

#

Im gonna try invalidate caches and restart now

ocean tundra Mar 22, 2021, 9:34 PM

#

works for me

#

#

#

@stone osprey remove the interface bit

stone osprey Mar 22, 2021, 9:36 PM

#

Hmmm... weird... what interface bit ?

ocean tundra Mar 22, 2021, 9:36 PM

#

use this as your class

#

no : IEquatable<EntityManager> bit

stone osprey Mar 22, 2021, 9:37 PM

#

Oh i already removed that ^^ But well... still those errors everywhere

#

Im gonna try to restart unity and rider... probably that helps

#

This is also interessting

ocean tundra Mar 22, 2021, 9:39 PM

#

yea for some reason it hasnt merged your partial entity manager

#

instead created a new one

#

is your asmref set correctly?

#

as your using rider your entitymanager partial shouldnt be grayed out like that

#

thats indicating there isnt another partial type

stone osprey Mar 22, 2021, 9:41 PM

#

Im gonna check that ref again... but im pretty sure that i set it correctly :/

ocean tundra Mar 22, 2021, 9:41 PM

#

and my folder looks different in rider to yours

#

i have that little unity.entities indicating its part of the entities package

stone osprey Mar 22, 2021, 9:42 PM

#

Huh ? Why does your folder looks like that ? 😮

ocean tundra Mar 22, 2021, 9:42 PM

#

maybe this:

stone osprey Mar 22, 2021, 9:42 PM

#

That fits

sturdy rune Mar 22, 2021, 9:42 PM

#

Do you have your code editor set as rider?

stone osprey Mar 22, 2021, 9:42 PM

#

Yes

ocean tundra Mar 22, 2021, 9:43 PM

#

well im very confused

#

it looks like your matching what ive done

stone osprey Mar 22, 2021, 9:43 PM

#

I did

ocean tundra Mar 22, 2021, 9:44 PM

#

close and reopen of both unity and rider did nothing?

#

what unity versions/rider version?

stone osprey Mar 22, 2021, 9:45 PM

#

Nope :/ 2020.1.6f1 and the latest rider version

#

2020.3.3

ocean tundra Mar 22, 2021, 9:45 PM

#

im on 2021.1.0b3

stone osprey Mar 22, 2021, 9:45 PM

#

I bet its some very, very stupid misttake somewhere

ocean tundra Mar 22, 2021, 9:46 PM

#

but i dont think that would be the cause

#

asmref have existed for a while now

#

my asmref raw:

    "reference": "GUID:734d92eba21c94caba915361bd5ac177"
}```

stone osprey Mar 22, 2021, 9:47 PM

#

AHHH WAIT

#

I deleted my previous file and added it again... now it looks different

ocean tundra Mar 22, 2021, 9:48 PM

#

that looks better

#

so weird

stone osprey Mar 22, 2021, 9:50 PM

#

Oh its not over yet xD

ocean tundra Mar 22, 2021, 9:50 PM

#

nooo

stone osprey Mar 22, 2021, 9:50 PM

#

ocean tundra Mar 22, 2021, 9:50 PM

#

delete the cs file

stone osprey Mar 22, 2021, 9:50 PM

#

Probably my folder is at the wrong place

ocean tundra Mar 22, 2021, 9:50 PM

#

and delete the asmref

#

start clear

#

make a folder

#

and then add the asmref

#

not the cs file

#

then finally after unity has finished compiling add the cs file

#

im thinking maybe you added the cs file first?
which would have triggered a ton of compile errors
and then added the asmref, but that didnt fix them for some reason

#

oh and make sure you start from 0 errors

stone osprey Mar 22, 2021, 9:52 PM

#

Oh man... yes that was the problem i guess ^^ Im gonna start fresh again... lets see how it goes this time

ocean tundra Mar 22, 2021, 9:53 PM

#

oh unity.. and its wonderful weird issues

stone osprey Mar 22, 2021, 10:01 PM

#

Im gonna kill myself

#

Sooo... i did a fresh start

#

Added a folder, added the reference file

#

Waited for unity... then added the cs file

#

Then waited again and replaced the default created class with the entitymanager

#

AND

#

THIS HAPPENS

ocean tundra Mar 22, 2021, 10:02 PM

#

well

stone osprey Mar 22, 2021, 10:02 PM

#

ocean tundra Mar 22, 2021, 10:02 PM

#

im even more confused

#

whats the name of the cs file?

stone osprey Mar 22, 2021, 10:03 PM

#

#

EntityManager

#

Im gonna try to change the name xD

ocean tundra Mar 22, 2021, 10:03 PM

#

maybe name the cs file something else

#

thats like the only difference i can see now

stone osprey Mar 22, 2021, 10:05 PM

#

Sooo :

#

ARGH

#

It doesnt even know any of the Unity.Entities stuff

#

Like IComponentData, its missing

pulsar jay Mar 22, 2021, 10:08 PM

#

safe lintel https://forum.unity.com/threads/some-questions-about-the-upcoming-isystembase-in...

What? If this really works this is a game changer. The internal stuff annoys the hell out of me 😬

ocean tundra Mar 22, 2021, 10:08 PM

#

when i click on the cs file it has this

#

stone osprey Mar 22, 2021, 10:10 PM

#

Mine has the same :

#

xD

#

What the hell is happening... it cant be that hard

ocean tundra Mar 22, 2021, 10:11 PM

#

looks like i wasnt the first to even discover this :/ weird your having issues

stone osprey Mar 22, 2021, 10:12 PM

#

Every single thing from Unity.Entities is missing now xD Interfaces, stuff like EndInitializationSystem... Even the entity struct itself

#

But... i can start it 😮

#

No errors shown in unity

ocean tundra Mar 22, 2021, 10:16 PM

#

so its just rider dying?

stone osprey Mar 22, 2021, 10:16 PM

#

It looks like its only rider

ocean tundra Mar 22, 2021, 10:17 PM

#

go File => invalidate caches and restart

stone osprey Mar 22, 2021, 10:17 PM

#

Oh i did that the fourth time in a row xD the errors stay

ocean tundra Mar 22, 2021, 10:18 PM

#

JetBrains Rider 2020.3.2?

stone osprey Mar 22, 2021, 10:18 PM

#

2020.3.3

ocean tundra Mar 22, 2021, 10:18 PM

#

ill update

stone osprey Mar 22, 2021, 10:19 PM

#

Thanks ^^

ocean tundra Mar 22, 2021, 10:19 PM

#

looks like theres 2020.3.4, ill update to that

stone osprey Mar 22, 2021, 10:19 PM

#

Thats also still interessting... Partial is still grey

#

Oh i see, im gonna update too

ocean tundra Mar 22, 2021, 10:27 PM

#

yea its all good for me

stone osprey Mar 22, 2021, 10:27 PM

#

Mine is still updating ^^ well... actually installing... somehow takes ages

ocean tundra Mar 22, 2021, 10:28 PM

#

yea took loads longer then i thought it would

stone osprey Mar 22, 2021, 10:31 PM

#

Annnnddd its still the same ^^ wuuuu

ocean tundra Mar 22, 2021, 10:31 PM

#

got to be something in your caches

stone osprey Mar 22, 2021, 10:32 PM

#

How does your solution look like ? Mines like this

#

Im gonna clean the solution/rebuild it

#

probably that helps

ocean tundra Mar 22, 2021, 10:33 PM

#

stone osprey Mar 22, 2021, 10:33 PM

#

Well cleaning works... rebuilding fails due to the resharp errors

ocean tundra Mar 22, 2021, 10:33 PM

#

mine has a library folder

stone osprey Mar 22, 2021, 10:33 PM

#

Yeah i see... mine has not 😮

#

Where are those packages installed by default ?

ocean tundra Mar 22, 2021, 10:34 PM

#

under library package cache

stone osprey Mar 22, 2021, 10:34 PM

#

Well its in there... as it should

ocean tundra Mar 22, 2021, 10:38 PM

#

update unity?

#

im out of ideas sorry

stone osprey Mar 22, 2021, 10:41 PM

#

Hmmm... i probably should

#

This is also interessting

#

It doesnt... find the .Entities

#

I removed the partial struct in this test here

#

This is also weird

#

That could atleast explain the many errors

ocean tundra Mar 22, 2021, 10:50 PM

#

yea i dont have that

#

the rest of my project is all sturctured with asmdefs

#

maybe thats it too?

#

i dont actaually have anything in assembly-csharp

#

nope sorry i do, just not much

#

like 3 files

#

and yea they have some .Entities stuff

stone osprey Mar 22, 2021, 10:52 PM

#

I dont use any asmdefs ^^ just the package manager... The error above only happens when theres a .cs next to the asmref file. Without it... theres one one reference to unity.entities

#

But as soon as i place a .cs file next to the reference file... it starts to throw errors at me

#

It wont find Unity.Entities anymore

ocean tundra Mar 22, 2021, 10:53 PM

#

any cs?

stone osprey Mar 22, 2021, 10:54 PM

#

Yep any...

ocean tundra Mar 22, 2021, 10:54 PM

#

or the partial one

stone osprey Mar 22, 2021, 10:54 PM

#

Any

ocean tundra Mar 22, 2021, 10:54 PM

#

maybe theres a bug with asmrefs in older unity...

stone osprey Mar 22, 2021, 10:55 PM

#

Well... i can run the editor... so im not sure if its really unity. But i also dont know how close unity and rider are coupled

ocean tundra Mar 22, 2021, 11:00 PM

#

@stone osprey sorry im all out of ideas

#

delete all library stuff/caches and .csprojs manually?

stone osprey Mar 22, 2021, 11:14 PM

#

Its ok, you helped a lot ^^ Well... im also out of ideas... but i actually dont wanna delete too much stuff, last time i did that the project was completly broken 😄

ocean tundra Mar 22, 2021, 11:14 PM

#

make a new test project

#

and see if its in there as well

#

and maybe update that project to see if its unity?

stone osprey Mar 22, 2021, 11:20 PM

#

I think im gonna try that new test project stuff tomorrow... im also a bit in fear regarding the unity update... last time i did that i was forced to update the entities package which resulted in a lot of changes xD

Me neither ^^ i havent that much freetime :p

ocean tundra Mar 22, 2021, 11:26 PM

#

not sure if ive done things wrong 😛

#

will see when i start stress testing more

sturdy rune Mar 22, 2021, 11:27 PM

I was going to say

#

it's not the netcoding that's a problem

#

dotsnet is awesome though so far

odd ridge Mar 23, 2021, 6:38 AM

#

how does one create a new queryable archetype at runtime?

#

for example, if I add the component Group1, it will create a new archetype with the Group1 component, which I can then query all entities of Group1 by querying Group1

#

I use the Group1 component as a way to collect all my entities that belong to that group together

#

but if I don't have a predetermined tag to query, how can I group entities together?

#

the use case is creating groups of RTS units. I want to create groups which when ordered, will move in a formation together

#

I have read about using NativeArray of entities, but iterating those entities would be random access. if I could modify the archetype with a group identifier instead, I could query the archetype with said identifier, and iterate the archetype with no random access

#

tldr, how can I create a collection of entities in dots such that I can iterate the collection with no random access. (the collection being a group of RTS units)

zenith wyvern Mar 23, 2021, 7:00 AM

#

odd ridge how does one create a new queryable archetype at runtime?

You can achieve that with shared components. You could have

struct SelectionGroup : ISharedComponentData
{
  int groupID;
}

#

Then you can filter by group id on the main thread before you run your foreach

#

I don't know if that's the right solution to what you're trying to do, but it's a solution

odd ridge Mar 23, 2021, 7:11 AM

#

zenith wyvern Then you can filter by group id on the main thread before you run your foreach

is there a lot of overhead to filtering?

ocean tundra Mar 23, 2021, 8:12 AM

#

@odd ridge I'm pretty sure it's actually quite quick

#

As shared component split up your Entitys into different chunks, so the cost is when adding/removing/changing shared components, not when filtering

amber flicker Mar 23, 2021, 8:52 AM

#

It’s pretty much the same as adding a tag - if this selection changes often you’ll have the cost of changing the archetype. If it’s for few operations on the selected entities. it’s usually better to iterate all and add to a native container. If they will be grouped over a longer time it’s likely worth the cost if the change in archetype. It’s all a trade off.

or do they mean something other than release candidate with RC here?

deft stump Mar 23, 2021, 1:24 PM

still if that would be the case, they would've included a version number

Quick question... does anyone know how we convert an object to an struct ? I passed a struct to an method via a (object) cast. Now i would like to get a ptr to that object, because i know that its a struct at that point. But well... its casted to an object :/ Any ideas how i could get a ptr to that struct easily ?

#

                unsafe {
                    var handle = GCHandle.Alloc(cmp, GCHandleType.Pinned);
                    var adress = handle.AddrOfPinnedObject();
                    var ptr = adress.ToPointer();
                    var sizeOfComponent = UnsafeUtility.SizeOf(type);

                    var parameters = new [] {entity, cmpType.TypeIndex, (object)adress, sizeOfComponent};
                    SetComponentDataRawInfo.Invoke(em, parameters);
                    handle.Free();
                }

Thats my code sofar... but i would love to get rid of the GC handle. Because i now that cmp is an struct that was casted to an object... any ideas ?

north bay Mar 23, 2021, 2:26 PM

#

Simple answer, you can't.
As soon as GC takes over the memory (which it does by you boxing the value) you have to pin the object to get an address to it.

ocean tundra As shared component split up your Entitys into different chunks, so the cost is ...

entities are grouped in chunks depending on the value of the shared component? as if it was a unique tag?

#

thanks, I must have missed this in the manual, I'll check it up

odd ridge Mar 23, 2021, 4:57 PM

#

amber flicker It’s pretty much the same as adding a tag - if this selection changes often you’...

yes, grouping units should be something that last for a least a couple minutes, unless the player spams grouping for no reason

#

my concern was that, if I would use a native container, the foreach would have a cache miss on every iteration, because there's no way to tell where in memory those entities are

pulsar jay Mar 23, 2021, 5:08 PM

#

odd ridge entities are grouped in chunks depending on the value of the shared component? a...

Yes they get one (multiple if too many) chunk per SharedComponentValue. I think grouping units in an RTS is a prime use case for SharedComponents

amber flicker Mar 23, 2021, 5:09 PM

#

not really sure why it's much better than adding a 'selected' tag unless there are many groups?

zenith wyvern Mar 23, 2021, 5:13 PM

#

I would probably prefer just iterating everything and using a native array. IMO you should only resort to shared components if you need to separate by chunk for performance reasons

#

Like if you have a lot of performance intensive work that needs to be done on your groups of entities per frame. Selection groups doesn't sound like it fits that criteria

Has anyone made use of RenderingLayerMasks with the hybrid renderer? I have a scriptable render pass that sets the renderingLayerMask on the FilteringSettings passed to DrawRenderers(). This works fine on game objects, but the entity equivalent is not getting filtered correctly. I can see the BuiltinMaterialPropertyUnity_RenderingLayer is set correctly on the entity in the inspector.

#

When I switch the filtering to use traditional layer masks instead, it works great. However, this layer is stored in the RenderMesh shared component, which isn't ideal if I want to turn the render feature on and off on specific entities at runtime.

#

This is the code I'm using to only draw render layer 4 (mask = 8)

uint renderLayerMask = 8;
var filteringSettings = new FilteringSettings(RenderQueueRange.all, -1, renderLayerMask);
context.DrawRenderers(renderingData.cullResults, ref drawingSettings, ref filteringSettings);

But all entities are getting rendered. For example, here is an entity on render layer 7 (mask = 64):

They are part of leak detection and can be quite expensive if you have full stack traces enabled.
Try to set leak detection to on or off

#

#

Error log

📎 message.txt

#

Its also quite interessting... that error log does complain about multiple components at the same time... not only one

#

"Identity has not been added... NetworkLocation has not been added..."

fluid kiln Mar 23, 2021, 7:22 PM

#

In "Uknown"

#

That's weird

#

I've never seen that

#

It's supposed to say the system name

stone osprey Mar 23, 2021, 7:24 PM

#

Hmmm... probably i call that buffer from the main thread at some point... that could explain the unknown atleast. What could explain the many listed components ? Is that normal ? ( Identity, NetworkLocation, NetworkRotation... not been added )

#

And is this caused by a .SetComponent operation ?

fluid kiln Mar 23, 2021, 7:24 PM

#

SetComponent or RemoveComponent

stone osprey Mar 23, 2021, 7:25 PM

#

Hmmm... I delete a bunch of entities once they leave the area of interest... thats a feature from my server framework. So what happens when i buffer .SetComponents() operation for an entity... but that entity gets deleted before the buffer is able to set those components ?

#

Would that explain that error message ?

zenith wyvern Mar 23, 2021, 7:26 PM

#

If that happened I think the exception would just say "The entity is null"

#

Errors from command buffers are extremely unhelpful in my experience

stone osprey Mar 23, 2021, 7:29 PM

#

Well such a exception would make more sense... And at the current state i never remove any components. So it why the heck does that happen... and i always call ".HasComponent" before i set one.

#

To make sure that this actually does not happen 😄

fluid kiln Mar 23, 2021, 7:29 PM

#

Impossible to tell from the stack trace

#

Do you use ecb outside of systems?

#

If so, you might want to use Entity Manager instead

stone osprey Mar 23, 2021, 7:32 PM

#

I use it outside the ecs for networking stuff. One of my scripts receives packets, converts them to components and uses a ECB instance to Add/Set components to an entity. That could be a possible reason. I only use an ecb here because i was told it offers better performance and does not interrupt the game flow

fluid kiln Mar 23, 2021, 7:33 PM

#

Yeah but operations from ecb aren't executed immediately

#

They are once the ecb is executed later in the frame

#

So if you do an ecb operation followed by a main thread operation, the ecb will not have been executed yet

#

For exemple

HasComponent<D>() //false```

#

From my understanding, at least

stone osprey Mar 23, 2021, 7:39 PM

#

Alright thanks... im gonna check the logic flow from my code. If that doesnt help im really gonna switch to the entity manager instead ^^

ocean tundra Mar 23, 2021, 7:45 PM

#

@stone osprey If you can stick with ECB, but maybe you need to make your own networkECBBarrier system

#

the default ECB systems playback at certan points (start/end) of their containing groups

#

For my networking im currently using EndSimGroup, but that does introduce that 1 frame delay

#

im planning on grouping up my networking systems and having a EndNetworkingECB group, that way users can update after that group and there wont be a frame delay

Since all the networking wizards are here, I have a conceptual question. I'm tryhing to make a top/down RPG but with the same combat system as LoL. I have a hard time coming up with what should be in my Input Buffer and how to attack / cast abilities

Yeah it's completely fair, it's your own funeral 😄

fluid kiln Mar 23, 2021, 7:56 PM

SO far the only thing in my input buffer is the destination the client wishes to go to

ocean tundra Mar 23, 2021, 7:57 PM

#

@fluid kiln lockstep or client server?

fluid kiln Mar 23, 2021, 7:57 PM

#

But now I'm tryhing to code abilities, should their cast be through RPC?

ocean tundra Mar 23, 2021, 7:57 PM

#

netcode right?

fluid kiln Mar 23, 2021, 7:57 PM

#

Idek what that means haha, netcode, server authoritative

bright sentinel Mar 23, 2021, 7:57 PM

#

fluid kiln Since all the networking wizards are here, I have a conceptual question. I'm try...

Hmm, I'd say as a naive approach you would have a bool for each type of attack (auto-attack, ability 1, ability 2, etc), and also the position where they clicked

ocean tundra Mar 23, 2021, 7:57 PM

#

yea based on my understanding of netcode, client would send a rpc to server to trigger the ability

bright sentinel Mar 23, 2021, 7:58 PM

#

Hm an RPC might also be a better solution 🤔

fluid kiln Mar 23, 2021, 7:58 PM

#

But the thing is, when I play with a client not on LAN, some frames of the Input buffer are lost

#

So "buttons" like "InteractedThisFrame" can be lost

ocean tundra Mar 23, 2021, 7:58 PM

#

lost?

#

as in packet lost?

#

netcode has a reliable pipline (reliable udp)

fluid kiln Mar 23, 2021, 7:59 PM

#

Not lost, but overwritten

#

I think

#

Like not all the frames in input buffer are guarateneed to be processed I think

#

That's why it's better to put streams like "direction"

ocean tundra Mar 23, 2021, 7:59 PM

#

when you say not on lan, your talking about client/server in the same host(unity process)? not over the internet?

fluid kiln Mar 23, 2021, 8:00 PM

#

Different processes yeah, I guess LAN wasn't right

#

I like the idea of RPCs for buttons anyway, but idk I'm in an awkward spot cause I'm trying abstract as much code as possible for players and npcs

#

But like if auto attacking sends an RPC every x second for every attack for the player, how does it work for the npc? I don't want it to send RPCs

bright sentinel Mar 23, 2021, 8:02 PM

#

Yeah, definitely seems like RPC isn't too good considering how often the data needs to be sent

#

Command stream seems a lot better

ocean tundra Mar 23, 2021, 8:02 PM

#

yea i built the same bug in my netcode 😛 client/server both in the same host (player clicks host and plays, no dedicated servers) when i sync stuff from/to local clients I override the whole buffer 😛

#

but my buffer is actually a ton of smaller buffers, every 'command' (rpc) is its own

#

something like auto attack would be a state, not a rpc , the rpc would be to enable/disable auto atack

fluid kiln Mar 23, 2021, 8:03 PM

#

I figured, but since an auto attack is just automatic casting of the ability "Attack", I would need a completely different logic for it than other abilities

ocean tundra Mar 23, 2021, 8:04 PM

#

hmm yea thats annoying

fluid kiln Mar 23, 2021, 8:04 PM

#

I'd like it to be homogenous to any other ability

ocean tundra Mar 23, 2021, 8:04 PM

maybe its more that any ablitly could be marked as 'auto cast'

So... Thats why i got that weird ecb exception... I have a system removing entities which are outside the players... "Chunk", but those can still receive updates because of the server settings... So that entity is marked for being deleted -> Deleted but still existing because of SystemComponents or however they are called -> Update coming and buffering .Set operation -> ecb tries to set a component to an entity which barely exists... Its alive, but not it components and it gets removed later on. Damn i wish theres a nicer reactive system solution

stone osprey Mar 23, 2021, 8:55 PM

#

Sooo... i have a bunch of entities i clearly dont want to iterate over by using Entities.ForEach() or queries. Is this somehow possible without adding .Exclude(); on every single query or system out there ? Some automatic tag which makes systems and queries ignore all entities with it ?

#

There's Disabled or Prefab

stone osprey Mar 23, 2021, 9:02 PM

#

fluid kiln Mar 23, 2021, 9:03 PM

#

Prefab is meant for prefabs, you probably want Disabled

zenith wyvern Mar 23, 2021, 9:03 PM

#

Functionally no. Just about what fits better in context

#

And you can filter for them separately in your queries

#

Actually I guess Prefab is different since Unity will remove the prefab component from the copy if you instantiate a prefab entity

stone osprey Mar 23, 2021, 9:21 PM

#

Thanks a lot ! Prefab works like a charm in my case 😄

#

Thats actually a huge advantage of unitys ecs... some other ecs i used in the past did not support that by default... which means i needed to "hack" myself into some methods for overwriting them

#

You could call GameObject.Find... methods in OnCreate

fluid kiln Mar 23, 2021, 9:26 PM

#

For GO you need a component with an Entity field and then in the editor you can map the GO in the component's field

ocean tundra Mar 23, 2021, 9:26 PM

#

but you need to be 100% sure that the scene containing that GO is the first one loaded

#

better to look into the conversion worldflow (subscenes) and use that

tight blade Mar 23, 2021, 9:27 PM

#

GO. I need to populate a scene object with a compute buffer and then have the system grab the reference that way

stone osprey Mar 23, 2021, 9:27 PM

zenith wyvern Mar 23, 2021, 9:28 PM

#

tight blade Anyone know how I could grab a reference to a particular game object in a system...

There's no easy way since gameobjects don't exist in OnCreate. You either hook into scene management callbacks or attach your data to an entity as a hybrid component https://docs.unity3d.com/Packages/com.unity.entities@0.17/manual/hybrid_component.html

ocean tundra Mar 23, 2021, 9:28 PM

#

oh does oncreate happen before inital scene load?

zenith wyvern Mar 23, 2021, 9:28 PM

#

You can get the hybrid component inside OnUpdate

#

Yes, ECS has no concept of scenes

ocean tundra Mar 23, 2021, 9:29 PM

#

yea but i thought that unity would load the initial scene first, then ecs stuff starts

tight blade Mar 23, 2021, 9:29 PM

#

huh. hmm. actually maybe I could create some kind of convoluted conversion workflow whereby I passed the compute shader reference to another system during conversion?

ocean tundra Mar 23, 2021, 9:30 PM

#

well the " convoluted conversion workflow " already exists 😛

zenith wyvern Mar 23, 2021, 9:30 PM

#

You shouldn't be passing it to systems, systems can query for it

#

GetSingletonEntity<MonoHoldingMyData>()

tight blade Mar 23, 2021, 9:31 PM

#

that must be a hybrid concept, because that seems to be an entity query for a monobehavior

ocean tundra Mar 23, 2021, 9:31 PM

#

see https://docs.unity3d.com/Packages/com.unity.entities@0.17/manual/conversion.html

zenith wyvern Mar 23, 2021, 9:31 PM

#

Yeah, that's what hybrid components are for

#

See the link I posted above

tight blade Mar 23, 2021, 9:32 PM

#

okay, thanks. yeah thats probably easier than what I had in mind. I was thinking that I would assign the conversion system itself a reference to a compute shader which it would take the value of from the first (and only) mono which it converted

#

and then something else would grab a reference to the conversion system

#

and take the reference that way

#

and that's all terrible

zenith wyvern Mar 23, 2021, 9:33 PM

#

Ideally you should never be referencing anything to do with conversion at runtime

#

You want to convert all your data into ECS friendly stuff during conversion then query for it at runtime

tight blade Mar 23, 2021, 9:34 PM

#

gotcha. sounds like a hybrid component is the way to go then

zenith wyvern Mar 23, 2021, 9:35 PM

There's a good thread about this discussing possible better solutions. We're stuck doing annoying stuff like that until Unity has a better process for pushing data into systems

you probably wont get that via a static method

so you need to write it manually

i think it uses a ComponentDataFromEntity

so make that outside the Foreach

#

then pass it down to the static method

fluid kiln Mar 23, 2021, 9:49 PM

#

I'll try outside the foreach

#

Ha it seems to work

#

Cool 😄 So if you create a local variable for EntityManager outside the foreach

#

You can use it within the burst foreach

#

Nice

ocean tundra Mar 23, 2021, 9:50 PM

#

yea that would make sence

#

i would double check the code gen output

#

make sure HasComponent is rewritten

tight blade Mar 23, 2021, 10:03 PM

#

blergh... cant quite... So, in this example, AddHybridComponent is doing what with that monobehavior? I notice the example didnt bother to recover the primary entity or anything before calling that

#

is it just creating a singleton entity that I could query for by that monobehavior?

#

I mean that's surely what I'd like it to be doing

#

wohoo! That is precisely what it seems to do!

#

well okay, that was a lot easier than I had expected

Let me fill buffers of entities in the editor PLEASEEEE

#

How do you fill a buffer of entities via IConvertToGameObject?

north bay Mar 23, 2021, 11:43 PM

#

You can get the entity of a converted gameobject by calling GetPrimaryEntity on the conversionSystem.

If the referenced gameobjects aren't part of the conversion process because they aren't inside the same subscene or child objects you have to use IDeclareReferencedPrefabs to hook them into the conversion.

fluid kiln Mar 23, 2021, 11:43 PM

#

Nevermind I can do it from Children

#

Oooh or maybe that

#

I'll try it thanks

fluid kiln Mar 24, 2021, 12:17 AM

#

The Unity.Entities.EntityManager has been declared as [ReadOnly] in the job, but you are writing to it.
Bro what the only thing I do is GetComponent and HasComponent ;_;

zenith wyvern Mar 24, 2021, 12:24 AM

#

You can't use entity manager inside bursted jobs. Use GetComponent/SetComponent

fluid kiln Mar 24, 2021, 12:24 AM

#

I'm trying to pass it to static methods cause I want to abstract some code

#

Not looking like a good idea so far

zenith wyvern Mar 24, 2021, 12:25 AM

#

If you're calling these from jobs then you need them to take a command buffer or a ComponentDataFromEntity

fluid kiln Mar 24, 2021, 12:25 AM

#

Can't GetComponent from ecb can you?

#

Oh a CDFE, okay I guess

zenith wyvern Mar 24, 2021, 12:26 AM

No, if you need to read a component from an entity you need to use a ComponentDataFromEntity

@stone osprey Hey did you ever get the partial + asmref working?

hollow sorrel Mar 24, 2021, 11:25 AM

how do I avoid boxing when using a list of interfaces that are structs?

odd ridge Mar 24, 2021, 2:27 PM

#

zenith wyvern I would probably prefer just iterating everything and using a native array. IMO ...

would you rather use a dynamic buffer component or a native array? also, can native arrays be stored inside a component?

zenith wyvern Mar 24, 2021, 2:29 PM

#

I guess it depends on how it's being used. If you need to store these groups or share them between jobs or systems then you should use dynamic buffers

#

But no, native arrays can't be stored on a component.

#

Only Unsafe ones

Hmm, I had a somewhat similar crash in player a while ago, it was due to a missing singleton. Could be the same? The error message was the same, but the callstack explicitly said that this was during a GetSingleton call, so it may not be as well. At least worth it to look through your scripts to see if you're missing a RequireSingletonForUpdate somewhere

You have to dispose any native container you allocate with TempJob or Persistent. No exceptions.

So does DeallocateOnJobCompletion not deal with this?

That's an attribute for a job struct

This is for a different system as I am now going through plugging leaks

zenith wyvern Mar 25, 2021, 5:29 PM

That attribute only works with native arrays, you should prefer just using container.Dispose(jobHandle) after your schedule the job

stable siren Mar 25, 2021, 5:30 PM

#

Yeah that is what I have done for most of them now. For this issue I am running a main thread system with several sequential forEach's. Do I have to add jobhandles to each and chain them so I can dispose the nativearray at the end?

zenith wyvern Mar 25, 2021, 5:31 PM

#

You can just pass in Dependency

#

At the end

#

As in the Dependency property, assuming you're not doing anything unusual with your job handles

#

Oh wait if it's a main thread system there shouldn't be any job handles involved

#

If that's the case just dispose it without passing in anything

Don't allocate a native container in a system constructor. If you're allocating a temp array for a job you need to do it at the start of OnUpdate and Dispose it at the end of OnUpdate

#

Or there's EntityManager.Exists

if(Exists(pistonEntity)) ?

zenith wyvern Mar 25, 2021, 6:15 PM

#

It's an entity manager function not a system function

#

When i use a native/unsafe hashmap... and allocate stuff with ".persistent"... i always need to dispose it by myself right ? Which means if i replace a component with a unsafeHashMap without disposing it... it will create memory leaks ?

ocean tundra Mar 25, 2021, 7:30 PM

#

yea that sounds right

stone osprey Mar 25, 2021, 7:31 PM

#

Ok thanks ^^

I posted this in www.reddit.com/r/unity3d , but it is so cool. Cool Video: https://youtu.be/Ws-7rqluv6w Take the left fish out on the boids example. Then raise the number until your system gets low performance. 2.5 million fish looks crazy, but also just 1fps. 500k looks ok at 7 fps. I'm posting this just because what Unity made as a demo project is soooo cool to tinker with numbers.

This ECS demo really impressed me. Unity DOTS.

ECS DOTS lets you have 10-1000x as many poly on screen by unlocking cores. So as more and more people play these games, they'll buy CPUs with more and more cores. Maybe in 6 years we have 1024 cores and stuff, so then we are able to render 1000x-100,000 more objects.

Download ECS examples that you can import right into your UNITY hub, from th...

From what I can see in this, the entity must exist at some point. Is there a way to find if it exists at all?

ocean tundra Mar 25, 2021, 8:52 PM

#

@stable siren Can you explain your question more?

#

If you destory a entity .Exists with the same entity will return false

#

that destoried entity is 'gone', and will be reused at some point in the future

stable siren Mar 25, 2021, 8:54 PM

#

I want to only run certain code if the piston/Diaphragm exist. This was my first attempt, I then tried manager.Exists(pistonEntity) but I don't think that works either

ocean tundra Mar 25, 2021, 8:54 PM

#

i would probably use both depending on how the setup works

#

if your piston entity or diaphragmEntity starts off 'null' or you destory and recrreate in runtime code
start with the != ENtity.null

#

then if that passes do a Em.Exists

#

(tho this may be unnessessory as EM.Exists probably does a != null check, but i cant look at the code atm

stable siren Mar 25, 2021, 8:57 PM

#

#

So this is how I was referencing them

ocean tundra Mar 25, 2021, 8:57 PM

#

so i think GetSingletonEntity will throw if the entity dosnt exist

stable siren Mar 25, 2021, 8:57 PM

#

But when I don't spawn them in (I have them starting as a gameobject) then an error is thrown and the logic doesn't seem to work

#

yes exactly

ocean tundra Mar 25, 2021, 8:58 PM

#

ah so your replacing GetSingletonEntity to make it safe?

#

You can use https://docs.unity3d.com/Packages/com.unity.entities@0.17/api/Unity.Entities.ComponentSystemBaseManagedComponentExtensions.HasSingleton.html#Unity_Entities_ComponentSystemBaseManagedComponentExtensions_HasSingleton__1_Unity_Entities_ComponentSystemBase_

#

for that

stable siren Mar 25, 2021, 8:59 PM

#

oh perf

fluid kiln Mar 25, 2021, 9:43 PM

#

About what percentage of your systems are burst? Because I feel like I'm putting too much effort in writing bad, not reusable code just for the sake of using burst.

#

Should I aim for a high percentage or does it matter not?

safe lintel Mar 25, 2021, 9:45 PM

#

+/- 90 id guess. burst everything you can, I dont know what bad not reusable code has to do with being burst compatible though

ocean tundra Mar 25, 2021, 9:45 PM

#

yea same for me

fluid kiln Mar 25, 2021, 9:46 PM

#

Some things I just have no idea how to do

#

Like dynamic buffer lookups

#

Writing for loop every time?

#

Can't even use a predicate

ocean tundra Mar 25, 2021, 9:46 PM

#

maybe a bit higher then 90% if you count all the code generated systems

safe lintel Mar 25, 2021, 9:47 PM

#

i dont know what a predicate is 🙂

ocean tundra Mar 25, 2021, 9:47 PM

#

nothing wrong with a for loop

fluid kiln Mar 25, 2021, 9:47 PM

#

Yeah but like for example I have a dynamic buffer of abilities, each of them have an ID component

#

Because I'm using netcode, everywhere I need to reference an ability I hav eto use its id

ocean tundra Mar 25, 2021, 9:47 PM

#

pretty sure you can make linq style code compatabile

fluid kiln Mar 25, 2021, 9:47 PM

#

So every I reference an abiltiy I have to write to same for loop GetComponent<ID>

#

I tried to make linq style extensions

#

But you can't use any form of delegate

#

Because they're oop

#

Also can't have dicitonary components

ocean tundra Mar 25, 2021, 9:48 PM

#

look at native lists sort

fluid kiln Mar 25, 2021, 9:50 PM

#

But Id on't think that's burstable

ocean tundra Mar 25, 2021, 9:50 PM

#

double check that, i think it is

safe lintel Mar 25, 2021, 9:50 PM

#

is ID part of netcode or your own code?

ocean tundra Mar 25, 2021, 9:50 PM

#

but not at my pc to see what i did

fluid kiln Mar 25, 2021, 9:51 PM

#

Well like, because the ability itself is an entity but not a ghost, I can't send it as an entity, I have to reference it by ID

ocean tundra Mar 25, 2021, 9:51 PM

#

oh so it is burst compatabile

fluid kiln Mar 25, 2021, 9:51 PM

#

So whenever the client or server receive the ID, I have to loop the buffer....

safe lintel Mar 25, 2021, 9:51 PM

#

im not using netcode but id be really surprised if it was built into netcode and not burst compat

ocean tundra Mar 25, 2021, 9:51 PM

#

BUT not a delegate, instead you make a struct and implement ICompare or something like that

fluid kiln Mar 25, 2021, 9:52 PM

#

ha yeah I understand

#

Yeah I did that with sort

#

But honestly rather than loop through the buffer I should have some way to store a dictionary

#

Where I can just do buffer[abilityId]

#

I could use an unsafehashmap but

#

It's unsafe and that intimidates me 😂

ocean tundra Mar 25, 2021, 9:53 PM

#

is the ability ID global for everything?

#

you could have a native hash map in a system

fluid kiln Mar 25, 2021, 9:54 PM

#

No cause an ability is an entity and every character that has this ability has an entity

ocean tundra Mar 25, 2021, 9:54 PM

#

but if your Ability list is attached to a entity and the id is to something in there its a bit harder

fluid kiln Mar 25, 2021, 9:54 PM

#

Since things can be added to it such as Cooldown etc

ocean tundra Mar 25, 2021, 9:54 PM

#

i see so you have
CharacterEntity

Child Ablitiy1
Child Ablitiy2
Child Ablitiy3
?

fluid kiln Mar 25, 2021, 9:55 PM

#

Pretty much yeah, I have another entity to hold the abilities

ocean tundra Mar 25, 2021, 9:55 PM

#

and the character entity has a buffer linking to them?

fluid kiln Mar 25, 2021, 9:55 PM

#

Character
Abilities
Ab1
Ab2

#

Yeah

#

Character has a component that references to the Abilities entity

#

THen i can do GetBuffer<Child>

ocean tundra Mar 25, 2021, 9:56 PM

#

im unsure with netcode but does it sync buffers?

#

and perseve order?

fluid kiln Mar 25, 2021, 9:56 PM

#

I wouldn't count on it, but yeah maybe I could use index

ocean tundra Mar 25, 2021, 9:56 PM

#

yea thats where i was going
