DOTS Gameplay: ComponentDataFromEntity

In this episode, we create a new Chaser Entity to showcase how to create relationships between Entities. We can add a component to hold another Entity's ID, then use the ComponentDataFromEntity structure to get access to its Translation. With a few extra tweaks to our existi...

They use ComponentDataFromEntity to make an entity follow anotehr one

I literally linked him that playlist earlier in this channel 😄

tawdry tree Jun 3, 2020, 5:31 PM

to be fair, the previous links were the other videos in that series

#

But yeah, might wanna watch all of em, Joker.

opaque ledge Jun 3, 2020, 5:32 PM

#

Its really hard for someone to teach DOTS basic over discord, so you better just watch every single video about DOTS on internet, i literally did

#

so you cant really 'learn' DOTS in this channel

cursive cosmos Jun 3, 2020, 5:33 PM

#

the problem is finding the ones that are new.

opaque ledge Jun 3, 2020, 5:33 PM

#

its much better if you watch those videos

#

only difference is JobComponentSystem to SystemBase from what i can see

#

you can even still use IJobForEach if you like, they arent removed yet

halcyon plume Jun 3, 2020, 5:34 PM

#

The problem is that most of the video is just out of date

opaque ledge Jun 3, 2020, 5:34 PM

#

i REALLY REALLY strongly urge you to watch CodeMonkey's videos

#

tell me a video that is out of date

#

i will 'translate' into current way

tawdry tree Jun 3, 2020, 5:34 PM

#

The game Academy.school videos are vry recent, and should not be out of date

deft stump Jun 3, 2020, 5:35 PM

#

@halcyon plume that video that was linked to you about chasers is not out of date. it's using systembase which is what you're using right now.

tawdry tree Jun 3, 2020, 5:35 PM

#

If those methods do not work for you, you might be on an older version

opaque ledge Jun 3, 2020, 5:35 PM

#

unless you are using videos from Entities 0.2 then you should be able to use it

#

you can still use the code from Entities 0.5

eisenhorn, add cs or csharp right after the first triple backticks for code highlighting. you also need a linebreak right after, so:
```cs[NO WHITESPACE HERE]
(code)
```

opaque ledge Jun 3, 2020, 5:44 PM

yeah not ref

tawdry tree Jun 3, 2020, 5:44 PM

cannot use component access method GetComponentDataFromEntity with the same type 'Translation' that is used in lambda expression parameters

opaque ledge Jun 3, 2020, 5:44 PM

it actually doesnt matter afaik

but i dont use any "ref" or "in" for Entity fields, you wont change it anyway

tawdry tree Jun 3, 2020, 5:45 PM

Seems to me like you possibly have something like this:

ForEach((Entity entity, ref Translation translation1) => {
  //translation1 already exists
  //so it doesn't let you do this:
  var translation2 = GetComponent<Translation>(entity);
})

storm ravine Jun 3, 2020, 5:50 PM

This error pretty straight forward and clean. You can't do that safely as it's potential race condition - you have type with write access and trying to access same type from other entity to which other thread can write.

@storm ravine That actually makes a lit of sense.
So you use IJobFor and add the amount of units in the schedule instead of using loops and shit.

One thing I'm curious about though is the prefab, is it possible to fetch the prefab entity in some other way since I kind of have it already in entity form in another class (Used the convertToEntity component)?

winter onyx Jun 3, 2020, 6:27 PM

#

Is there any reason a job will take longer to dequeue and execute on Android and iOS than on desktop or WebGL platforms?

#

when the job itself actually takes less than a frame's worth of time to execute

storm ravine Jun 3, 2020, 6:28 PM

@cursive cosmos I'm not using that 🙂 Just wrote for you. Where you'll get params - up to you

winter onyx Jun 3, 2020, 6:28 PM

#

in other words, does Unity schedule jobs on mobile devices in an idiosyncratic way

#

SpriteShapeController uses jobs internally to recreate its geometry, and for some reason it just updates itself less frequently on my Android and iOS devices than on other platforms

#

this is a new error, Sprite Shape v2 series did not exhibit this problem

#

this has to do with job scheduling

#

which is the main difference in the code

#

so I'm wondering if there's just a checkbox or preference I'm supposed to set

opaque ledge Jun 3, 2020, 6:29 PM

#

mobile devices forces vsync, maybe thats why ? no idea

winter onyx Jun 3, 2020, 6:29 PM

#

it's most obvious if I'm using sprite shape controller to draw a line between a point and the user's finger, for example, where you can see the line art is not being updated every frame, even if the points requested to be drawn are

#

no

#

it's not going to be that

#

it's got something to do with job scheduling which is why i'm asking the DOTS people here

opaque ledge Jun 3, 2020, 6:30 PM

#

have you profile it ?

winter onyx Jun 3, 2020, 6:30 PM

#

yes, there is no performance issue with the sprit eshape controller job itself

#

i'm asking if there's a reason that unity would delay running a job

#

for no good reason, basically

#

i'm sure they have a reason

#

but if there'sd something platform specific regarding when jobs run

opaque ledge Jun 3, 2020, 6:31 PM

#

well, hope you find your answer

winter onyx Jun 3, 2020, 6:34 PM

#

so no one knows how to just

#

force jobs to run

#

i get that there's JobHandle.ScheduleBatchedJobs or whatever

#

it's like the most basic feature of dots right? job scheduling

hollow sorrel Jun 3, 2020, 6:44 PM

#

you're scheduling your job from ecs right?

winter onyx Jun 3, 2020, 6:44 PM

#

sure

#

i have a JobHandle, i would like the code inside the job handle to run you know, after i call a line of code

#

.Complete is not it

hollow sorrel Jun 3, 2020, 6:45 PM

#

a system always finishes the previous frame's job before scheduling new one so typically should be always every frame

#

did you set Dependency?

winter onyx Jun 3, 2020, 6:45 PM

#

no

#

no dependencies

hollow sorrel Jun 3, 2020, 6:45 PM

#

using SystemBase?

#

nvm i think Dependency isn't necessary anymore, been a while since i last used

#

only other thing i can think of is maybe you have an ordering issue

storm ravine Jun 3, 2020, 6:48 PM

#

nvm i think Dependency isn't necessary anymore, been a while since i last used
@hollow sorrel Dependency always necessary if you scheduling, codegen track it for you in SystemBase ForEach, but for regular jobs in system you should track them by yourself.

hollow sorrel Jun 3, 2020, 6:49 PM

#

yea i mean i'm assuming he's using ForEach

#

or maybe i misunderstood

#

@winter onyx if you're scheduling your own job you gotta do Dependency = muhjobhandle in the system because otherwise the system won't keep track of it

#

i.e. it won't force complete it next frame because it doesn't know that it's running

#

could complete 10 frames later if it's slow

opaque ledge Jun 3, 2020, 6:52 PM

#

it sounds like platform issue tho, not really code

winter onyx Jun 3, 2020, 6:52 PM

#

i didn't write this, unity did

#

for what it's worth

#

we're talking about SpriteShapeController

#

there's nothing wrong with the way they schedule jobs on sprite shape controller

#

the issue appears to be, pretty much unambiguously, that on mobile devices jobs are just not run as frequently as on desktop devices

#

there are two suspicious jobs-related calls on SpriteShapeController

        internal void BakeMeshForced()
        {
            if (spriteShapeRenderer != null)
            {
                var hasSplineChanged = HasSplineDataChanged();
                if (!spriteShapeRenderer.isVisible && hasSplineChanged)
                {
                    BakeMesh();
                    Rendering.CommandBuffer rc = new Rendering.CommandBuffer();
                    rc.GetTemporaryRT(0, 256, 256, 0);
                    rc.SetRenderTarget(0);
                    rc.DrawRenderer(spriteShapeRenderer, spriteShapeRenderer.sharedMaterial);
                    rc.ReleaseTemporaryRT(0);
                    Graphics.ExecuteCommandBuffer(rc);
                }
            }
        }

and

                var spriteShapeJob = new SpriteShapeGenerator() { m_Bounds = bounds, m_PosArray = posArray, m_Uv0Array = uv0Array, m_TanArray = tanArray, m_GeomArray = geomArray, m_IndexArray = indexArray, m_ColliderPoints = m_ColliderData };
                spriteShapeJob.Prepare(this, m_ActiveShapeParameters, maxArrayCount, shapePoints, shapeMetaData, m_AngleRangeInfoArray, m_EdgeSpriteArray, m_CornerSpriteArray);
                jobHandle = spriteShapeJob.Schedule();
                spriteShapeRenderer.Prepare(jobHandle, m_ActiveShapeParameters, m_SpriteArray);
                JobHandle.ScheduleBatchedJobs();

#

there are no dependencies or anything

hollow sorrel Jun 3, 2020, 6:54 PM

#

oh it's monobehaviour stuff, i misunderstood mybad

winter onyx Jun 3, 2020, 6:56 PM

#

i sort of just want to know, is there a method

#

anywhere, in the whole api

#

that just, forces the jobs to run now?

#

i get that the answer might be, no

#

i mean maybe there's something extremely buggy with android, and there's a job that runs instantly on the desktop that takes seconds on the android device

storm ravine Jun 3, 2020, 6:57 PM

#

JobHandle.ScheduleBatchedJobs(); is forces the jobs to run

winter onyx Jun 3, 2020, 6:58 PM

#

that exists for sure

#

the thing is, we sort of know that it doesn't do that

#

it just wakes the threads and says for them to check

#

it doesn't actually do it

#

so the answer is no

#

you can't do it

#

that's okay with me, i just wanted to make sure

storm ravine Jun 3, 2020, 6:58 PM

#

It do it

#

Reason for delay also described by Unity

#

The job system intentionally delays job execution until you call ScheduleBatchedJobs manually because the cost of actually waking up worker threads can be expensive. Thus a good default is to delay the actual kick until a few jobs have been scheduled. Generally if you are scheduling a bunch of jobs in a loop, wait with kicking the jobs until the end of the loop. If you do significant amounts of work on the main thread between scheduling jobs, then it can make sense to ScheduleBatchedJobs between each job.

winter onyx Jun 3, 2020, 6:59 PM

#

yeah

#

i mean who knows, we don't have the unity source, at the end of the day

#

we don't know when it actually does it

storm ravine Jun 3, 2020, 6:59 PM

#

It does it at exact call

#

ScheduleBatchedJobs

winter onyx Jun 3, 2020, 6:59 PM

#

maybe it's running the job on time on all devices, but this "execute command buffer" call is delayed on android

#

that's my only other hypothesis

#

that call is just obviously main-thread-synchronous

storm ravine Jun 3, 2020, 7:00 PM

#

You should understand that - starting job execution not equal "all done"

#

For example you schedule first job and call it, and it start running it

#

and depends on many things (cpu, code complexity etc.) it will finish after 10 or 100 ticks (abstract)

#

If you not force it to complete right now

winter onyx Jun 3, 2020, 7:01 PM

#

Jobs have a Run function that you can use in place of Schedule to immediately execute the job on the main thread. You can use this for debugging purposes.

#

this is what i think i was looking for

storm ravine Jun 3, 2020, 7:01 PM

#

It's running on main thread

#

a bit different thing

#

only on one main thread

winter onyx Jun 3, 2020, 7:01 PM

#

the job itself

#

is instantaneous

#

it finishes in microseconds

#

the spriteshape's job that it is scheduling

#

it doesn't have a performance issue there

#

granted, i do not know how ot profile the specific job

#

there is no result for "how to profile unity job"

hollow sorrel Jun 3, 2020, 7:02 PM

#

shouldn't .complete do the same thing

storm ravine Jun 3, 2020, 7:02 PM

#

ProfileMarker

winter onyx Jun 3, 2020, 7:02 PM

#

it just doesn't

#

all that those interactions are doing

storm ravine Jun 3, 2020, 7:02 PM

#

Complete does same thing for Parallel scheduled jobs

winter onyx Jun 3, 2020, 7:02 PM

#

is asking, gently, for unity to schedule things

#

it doesn't actually force them to occur

#

job.Run forces it to occur

#

which is really an issue with the API

#

it's not anyone's fault

storm ravine Jun 3, 2020, 7:03 PM

#

Uffff.. it DOES that's all.

hollow sorrel Jun 3, 2020, 7:03 PM

#

.complete is synchronous afaik
code after it doesn't run until the code in the job is completed

#

it's not a suggestion

storm ravine Jun 3, 2020, 7:03 PM

#

But complete on mainthreaded code will be overhead

winter onyx Jun 3, 2020, 7:03 PM

#

that's true

storm ravine Jun 3, 2020, 7:03 PM

#

because of schedule

winter onyx Jun 3, 2020, 7:04 PM

#

but i'm not interested in just watching the screen freeze

#

for 4 seconds

#

do you see what i mean?

storm ravine Jun 3, 2020, 7:04 PM

#

Run will do the same

winter onyx Jun 3, 2020, 7:04 PM

#

we don't know if it freezes for 3.999s of sleeping, followed by 0.001s of actual job execution

storm ravine Jun 3, 2020, 7:04 PM

#

it will stall main thread

winter onyx Jun 3, 2020, 7:04 PM

#

no, what i'm saying is it won't

storm ravine Jun 3, 2020, 7:04 PM

#

It DOES

winter onyx Jun 3, 2020, 7:04 PM

#

there's only 0.001s of actual job execution

storm ravine Jun 3, 2020, 7:04 PM

#

I told you difference

winter onyx Jun 3, 2020, 7:04 PM

#

clearly on android it's sleeping the thread

#

do you see?

#

i don' tknow it doesn't matter, don't worry about it

#

and i don't know if unity devs hang out in this chat

#

i mean they'll understand exactly what the issue is

#

.Complete is just waiting for the task to complete, and gently asks the scheduler to "run it now", it does not force the scheduler to actually do it

#

there's a degenerative situation, which i can reproduce on android, where the scheduler is delaying the actual execution of the task

storm ravine Jun 3, 2020, 7:06 PM

#

Main difference with Run is it not Job anymore technically (as you expect it) it become "method" on mainthread (and if it uses Burst it become bursted method)

winter onyx Jun 3, 2020, 7:06 PM

#

when i say actually do it

#

i mean you just don't know how this works

#

which is fine

#

you could just say i don't know

#

it was helpful

storm ravine Jun 3, 2020, 7:06 PM

#

.Complete is just waiting for the task to complete, and gently asks the scheduler to "run it now", it does not force the scheduler to actually do it
@winter onyx wrong

Complete FORCES all jobs in JH chain DO all work using every thing they can (main thread and worker threads if it parallel)

#

It become similar as calling code synchronous on main thread

#

same as Run

#

Difference in performance here only Schedule

winter onyx Jun 3, 2020, 7:08 PM

#

Complete just has the main thread wait until the jobs are finished, and gently asks the scheduler to start jobs now

storm ravine Jun 3, 2020, 7:08 PM

#

Not at all

winter onyx Jun 3, 2020, 7:08 PM

#

the furthest i can see that Complete calls is

#

    [NativeMethod(IsFreeFunction = true)]
    [MethodImpl(MethodImplOptions.InternalCall)]
    private static extern void ScheduleBatchedJobsAndComplete(ref JobHandle job);

#

that's what it does

#

and i bet, i would be a lot of money, that if we looked at the unity engine source code

#

for what that concretely does

hollow sorrel Jun 3, 2020, 7:10 PM

#

an answer from eiz on this might as well be same as getting an answer from a unity dev

#

dunno why you're dismissing it with "i don't know so neither do you"

winter onyx Jun 3, 2020, 7:10 PM

#

it will look like

ask the scheduler to run all the jobs, possibly prioritizing the job i was passed

wait until the job i was passed is finished

#

the scheduler's internal code looks like

i have a bunch of threads with queues, they will sleep until they have work to do

tells those threads what to do using queues

#

and what i'm trying to say is

storm ravine Jun 3, 2020, 7:11 PM

#

The JobSystem automatically prioritizes the job and any of its dependencies to run first in the queue, then attempts to execute the job itself on the thread which calls the Complete function.

winter onyx Jun 3, 2020, 7:11 PM

#

that unity wrote something wrong in how the android scheduler works

#

yes

#

attempts being the operative word here

#

it doesn't execute the job

storm ravine Jun 3, 2020, 7:11 PM

#

I personally discussed scheduling with DOTS team, and Complete behaviour (Complete itself) equal to Run. Overhead before complete is Schedule.

#

It does.

winter onyx Jun 3, 2020, 7:12 PM

#

then i guess there's a regression in the unity code

#

then it's just a bug?

storm ravine Jun 3, 2020, 7:13 PM

#

Show your setup

#

You suing SpriteShapeController?

winter onyx Jun 3, 2020, 7:14 PM

#

yes we're talking about unity code

#

i don't even have control about when it calls its own job

#

it's just a bug in a package unity authored

#

and unfortunately the only way to get the source nowadays is in the PackageCache directory

#

i would loev to just

#

reference you the code

#

i mean i'm not braindead 🙂

#

i mean clearly there's a regression

#

i just have diagnosed it already

#

i think .run is what i will need

#

i'm about to find out

cursive cosmos Jun 3, 2020, 7:17 PM

#

I think I need to abandon the idea of converting game objects to entities, it's just causing me more headache than my codemade mesh cube x)

winter onyx Jun 3, 2020, 7:17 PM

#

it's not 100% clear to me

#

how to actually IJobExtensions.Run a job handle yet...

opaque ledge Jun 3, 2020, 7:17 PM

#

@cursive cosmos What seems to be problem

cursive cosmos Jun 3, 2020, 7:20 PM

#

Nah, just having a hard time finding out how I send objects into systems that are not components, but complete entities.

#

Might have to do it the singleton way

winter onyx Jun 3, 2020, 7:20 PM

#

my feeling is, just from looking at how the sprite shape controller is written, there is a bug in the job scheduler

#

in the most recent unity version

#

or that the meaning of the API has changed, between point versions

#

and you know, i just can't do unity's job for it

#

building an android application on combinations of sprite shape packages and unity editor versions

#

i would rathe rjust fix the bug

#

they won't do that either, they just won't

#

it's like the targeting arrow in my game right? and all of a sudden it just starts working crappily on mobile devices

#

i will credit you that .BakeMesh().Complete() fixed the issue 🙂

storm ravine Jun 3, 2020, 7:25 PM

#

how to actually IJobExtensions.Run a job handle yet...
@winter onyx you can't as JobHandle is result of scheduling, which not exists if you Run on main thread.

#

For JobHandle you only have Complete

winter onyx Jun 3, 2020, 7:26 PM

#

i mean, i'm not supposed to do that

storm ravine Jun 3, 2020, 7:26 PM

#

I told about your it's most obvious if I'm using sprite shape controller to draw a line between a point and the user's finger, for example, where you can see the line art is not being updated every frame, even if the points requested to be drawn are setup 🙂 You getting sprite shape and moving spline points and call BakeMesh right?

winter onyx Jun 3, 2020, 7:26 PM

#

you're not supposed to call bakemesh

#

the sprite shape knows when it has changed

#

the issue was the scheduler

#

i mean, clearly i would like to use a worker thread to render the mesh (the profiler puts it at 4ms, which still seems extremely high to me)

#

for two points

#

on android, the job scheduler just sleeps threads more

#

it's going to be that simple

#

i'm sure some unity engineer had a good reason for doing that

#

this was a regression, no code changed other than spriteshape and the unity editor

storm ravine Jun 3, 2020, 7:29 PM

#

SpriteShapeGenerator itself is IJob which only use 1 thread and as you call complete on main thread it will use only main thread 🙂

winter onyx Jun 3, 2020, 7:29 PM

#

to be clear

#

listen i mean, did i write the sprite shape generator?

#

no

#

am i using it wrong? no

#

am i now doing something i'm not supposed to be doing? yes

#

does it fix my issue? yes

#

am i braindead? no

#

that's sort of what i wanted, i did want to do something that i wasn't doing before, that i know i'm not supposed to be doing

#

because i can't wait a week for Unity QA to tell me to install the latest version of the editor and try again

storm ravine Jun 3, 2020, 7:31 PM

#

Write your own

#

That's all

winter onyx Jun 3, 2020, 7:31 PM

#

yeah i think that's the moral of the story

opaque ledge Jun 3, 2020, 7:31 PM

#

😄

storm ravine Jun 3, 2020, 7:31 PM

#

If you don't wan't to wait 😉

winter onyx Jun 3, 2020, 7:31 PM

#

i mean if there was a way to freeze the package version

#

there isn't

#

it just upgrades for you

storm ravine Jun 3, 2020, 7:31 PM

#

We wrote own everything 🙂

#

Move it to Packages folder

winter onyx Jun 3, 2020, 7:32 PM

#

yeah, this sort of confirms people's beliefs

storm ravine Jun 3, 2020, 7:32 PM

#

from library

hollow sorrel Jun 3, 2020, 7:32 PM

#

job scheduler having a bug is completely different from spriteshape generator having a bug tho

storm ravine Jun 3, 2020, 7:32 PM

#

and it become local package

winter onyx Jun 3, 2020, 7:32 PM

#

the popular opinion, years on, is that this stuff is garbage

#

the job scheduler definitely has a bug

hollow sorrel Jun 3, 2020, 7:32 PM

#

you could be right that job scheduler has a bug but it's a big claim because a lot of people are using it including on android and haven't reported same
you could be first to have these specific circumstances that trigger it but i'd be more inclined to think spriteshapegenerator or use thereof is the issue

#

i mean

winter onyx Jun 3, 2020, 7:33 PM

#

no dude

hollow sorrel Jun 3, 2020, 7:33 PM

#

job scheduler has existed even before ecs

winter onyx Jun 3, 2020, 7:33 PM

#

there are maybe a handful of people using it on mobile devices

#

at any scale

#

and also have the ability to understand what's going on

opaque ledge Jun 3, 2020, 7:33 PM

#

imo you should tone it down a little, you should relax, if you think its a bug go report it

winter onyx Jun 3, 2020, 7:33 PM

#

i think the scheduler was actualyl correct until very very recently

#

this is a new bug

#

yeah don't get me wrong you guys don't work for unity

#

this is for them not for you

#

it's infuriating to say the least

storm ravine Jun 3, 2020, 7:34 PM

#

For them use bug reporter, then it will be in their field of view 🙂

opaque ledge Jun 3, 2020, 7:34 PM

#

hope i wont encounter any problem when i build my game for Android 😅

storm ravine Jun 3, 2020, 7:34 PM

#

In addition I can write them directly

#

But bug reporter also handful thing

cursive cosmos Jun 3, 2020, 7:35 PM

#

Anyone who can punt me in the right direction regarding sending variables from other classes into a SystemBase class?
Or is that maybe nothing I should be doing in the first place? ^^;

opaque ledge Jun 3, 2020, 7:35 PM

#

SharedStatics perhaps, you can also make a singleton MB

winter onyx Jun 3, 2020, 7:35 PM

#

the bug reporter doesn't even upload projects correctly on macos

#

and i have a fiber connection

#

to put in perspective

#

like obviously i care

#

i want it to be good

storm ravine Jun 3, 2020, 7:36 PM

#

Anyone who can punt me in the right direction regarding sending variables from other classes into a SystemBase class?

@cursive cosmos Depends on many thing. Mutable\immutable data?

hollow sorrel Jun 3, 2020, 7:36 PM

#

submit a bug about that nervous

winter onyx Jun 3, 2020, 7:36 PM

#

i've reported a bug about spriteshape before, funny enough, related to the jobs

#

and it got fixed

#

yeah exactly 🙂

#

but it took 20 days

#

it was a lot of back and forth about update to the latest editor version

#

which by the time i did that, well, there was yet another version

cursive cosmos Jun 3, 2020, 7:36 PM

#

@storm ravine It's a gameobject that has been converted to an entity and will serve as the type of object I will spawn. So basically just an Entity with components

winter onyx Jun 3, 2020, 7:37 PM

#

when the QA person actually got around to check

#

you know?

#

and their script just says, make sure they're using the latest editor version, in a product that constantly has regressions

#

in comparison, the unreal source code is just open, i suppose you can go and fix it, i mean it's equally riddled with bugs and there's just no support whatsoever, you need to poach Epic Games employees

#

so it's not like there's a 100% better alternative

storm ravine Jun 3, 2020, 7:38 PM

#

Anyone who can punt me in the right direction regarding sending variables from other classes into a SystemBase class?

@cursive cosmos you can do SharedStatic, you can have entity which will hold data itself (class\struct ICD)

cursive cosmos Jun 3, 2020, 7:38 PM

#

Cool, will check it out.

storm ravine Jun 3, 2020, 7:39 PM

#

For example you'll have singleton entity which hold your prefab entity and use that singleton entity in systems

cursive cosmos Jun 3, 2020, 7:39 PM

#

oh, the prefab is fully converted to an entity, so I don't think it's necessary to make a container for it, no?

storm ravine Jun 3, 2020, 7:40 PM

#

Yep

#

If only one prefab

#

it will already behave as singleton

winter onyx Jun 3, 2020, 7:40 PM

#

listen big thanks though you did fix it

#

.Complete worked

#

i won't argue with results 🙂

storm ravine Jun 3, 2020, 7:40 PM

#

👍

#

Also about performance

#

Did burst enabled?

winter onyx Jun 3, 2020, 7:41 PM

#

lemme check

storm ravine Jun 3, 2020, 7:41 PM

#

as sprite generator job wraps Burst attribute to preproc define

#

I'm not using that package then don't know if it has dedicated checkbox for burst in sprite shape generator

#

Which will enable define

winter onyx Jun 3, 2020, 7:43 PM

#

yeah

#

i guess i was doing a development build anyway

storm ravine Jun 3, 2020, 7:43 PM

#

in development build what timeline shows?

#

has (Burst) after job name?

winter onyx Jun 3, 2020, 7:43 PM

#

installing the Jobs package imports Newtonsoft Json 😿

storm ravine Jun 3, 2020, 7:44 PM

#

Yep newtonsoft dependencies which appears\disappears between versions annoying

#

Why Jobs package?

#

You don't need Jobs package afaik

#

as it uses UnityEngine jobs

#

Jobs package only contains couple of additional Job types

winter onyx Jun 3, 2020, 7:45 PM

#

no it does not say burst

#

but right now i don't see the job it schedules at all

#

probably because i'm using complete now?

#

i mean it's not running on any of the workers

#

i see physx jobs

#

which are also not burst

storm ravine Jun 3, 2020, 7:46 PM

#

yep

#

Remove complete

#

for tests

#

OR

#

open burst inspector

#

📎 unknown.png

#

Is it greyed out for you?

winter onyx Jun 3, 2020, 7:47 PM

#

first i must fix the newtonsoft thing

#

if i want that inspector 🙂

storm ravine Jun 3, 2020, 7:47 PM

#

Burst package not require newtonsoft, It only install math lib itself

cursive cosmos Jun 3, 2020, 7:48 PM

#

is sharedStatic basically a global variable in a way?

winter onyx Jun 3, 2020, 7:48 PM

#

ah i installed the wrong package

#

one sec

opaque ledge Jun 3, 2020, 7:48 PM

#

yup something like that

storm ravine Jun 3, 2020, 7:48 PM

#

Why Jobs package?

You don't need Jobs package afaik
🙂

#

After installing burst restart editor

winter onyx Jun 3, 2020, 7:49 PM

#

i meant that it says it does not say burst

#

sorry

#

it's spinning

storm ravine Jun 3, 2020, 7:49 PM

#

After installing restart 🙂 It's required 🙂

winter onyx Jun 3, 2020, 7:49 PM

#

gochtya

storm ravine Jun 3, 2020, 7:50 PM

#

As it will throw you errors after installing which will disappear after restart

#

is sharedStatic basically a global variable in a way?
@cursive cosmos it like regular C# static fields with some restrictions for Burst

humble falcon Jun 3, 2020, 7:51 PM

#

@cursive cosmos if you have problem regarding instantiating entity. Maybe the ECS Samples from Unity is worth to look at 🙂

winter onyx Jun 3, 2020, 7:51 PM

#

okay i'm oing to try running without .Complete and regular (not development) build on android

#

see how it goes

#

it looks like it burst compiled

storm ravine Jun 3, 2020, 7:51 PM

#

Just check in editor first

#

as with burst it now can be veeeeeery tiny and hard to find on timeline 🙂

cursive cosmos Jun 3, 2020, 7:52 PM

#

Nah, instantiating an entity was not confusing, it was how the system works and How I can transfer over data from normal mono classes to systemBase classes :)

But does this mean that if I try to do this with sharedstatics, is there a risk that the system job will run before the static is set?

storm ravine Jun 3, 2020, 7:53 PM

#

https://docs.unity3d.com/Packages/com.unity.burst@1.3/manual/index.html?q=FunctionPointer#shared-static

#

this part specifically It is recommended to always initialize the shared static field in C# from a static constructor before accessing it from HPC#. Not initializing the data before accessing it can lead to an undefined initialization state.

cursive cosmos Jun 3, 2020, 7:54 PM

#

yep, just read that ^^;

#

So then is the question, does system jobs start running before a mono OnStart method?

#

Probably not.

winter onyx Jun 3, 2020, 7:56 PM

#

lol

#

yes you're right

#

it's very tiny

#

it was 0.008ms

#

SpriteShapeGenerator (Burst)

storm ravine Jun 3, 2020, 7:56 PM

#

Yes now it burst compiled

winter onyx Jun 3, 2020, 7:56 PM

#

in Worker 14 of 32

storm ravine Jun 3, 2020, 7:56 PM

#

Without complete

#

With complete it will be similar

#

maybe a bit longer like 0.01ms

#

Which will be fine now? In comparison with 4ms?

winter onyx Jun 3, 2020, 7:57 PM

#

yeah without complete

#

i am compiling for the device now

#

once build without profiler one with

#

development build unchecked

storm ravine Jun 3, 2020, 7:57 PM

#

Use release build

winter onyx Jun 3, 2020, 7:57 PM

#

yeah that's what i mean

storm ravine Jun 3, 2020, 7:57 PM

#

as dev build (same as editor) has safety checks overhead

winter onyx Jun 3, 2020, 7:58 PM

#

i unchecked safety checks

#

f those am i right

storm ravine Jun 3, 2020, 7:58 PM

#

it will x5-10 faster than now

opaque ledge Jun 3, 2020, 7:58 PM

#

I meant to ask Eizen, how is blobassets represented in chunks exactly ? when we build a blob and put into a component every component will 'reference' to a single place which holds the value, but where does that value live exactly ?

storm ravine Jun 3, 2020, 7:58 PM

#

Yes if you unchecked it will be similar to build by performance (but not completely, release build will always be faster)

winter onyx Jun 3, 2020, 7:59 PM

#

i'm going to go make a coffee while this compiles

storm ravine Jun 3, 2020, 7:59 PM

#

Blobs is preallocated 200mb per scene.

winter onyx Jun 3, 2020, 7:59 PM

#

this has been very helpful thank you

storm ravine Jun 3, 2020, 7:59 PM

#

When you use blobs you store just ptr to memory address

#

this is why blobs use many ref structures

opaque ledge Jun 3, 2020, 7:59 PM

#

per scene ? you mean per world ?

storm ravine Jun 3, 2020, 7:59 PM

#

for preventing of getting wrong pointer

#

per scene

opaque ledge Jun 3, 2020, 8:01 PM

#

so how the process works then, will it be a cache miss just to retrieve that value ? or Unity will prefatch that value first and then run process ForEach ?

#

Eizen be like "how do i explain this in a way that a scrub can understand"

#

i am not really into details, but was just wondering, since whole idea of ECS is to be able to have all the data you need in a cache line or smth right ?

storm ravine Jun 3, 2020, 8:03 PM

#

No I just trying to find conversation in Unity slack or on forum, where I described that couple of times long time ago

opaque ledge Jun 3, 2020, 8:03 PM

#

ah okay fair

storm ravine Jun 3, 2020, 8:04 PM

#

Well can't find that, will explain it shortly

#

Or send you to source code of Blob.cs 😄

#

As it's not so short to explain

opaque ledge Jun 3, 2020, 8:07 PM

#

eh dw about it then 😄

#

like i said, i am not really into details, but was just wondering since it would be a cache line miss or smth

storm ravine Jun 3, 2020, 8:08 PM

#

It mostly unmanaged memory

#

they store data in blobs as batches

#

Look at BlobAssetBatch

vagrant surge Jun 3, 2020, 8:11 PM

#

@opaque ledge accessing stuff from a blob is likely to be in cache, because you likely are accessing the same blob a lot from a query

#

dont worry about every single cache miss lol

storm ravine Jun 3, 2020, 8:11 PM

#

yeah vblanco tl;dr valid 😄

vagrant surge Jun 3, 2020, 8:11 PM

#

unity does N cache misses where N is number of comps in your query per-chunk

storm ravine Jun 3, 2020, 8:11 PM

#

I'm just empty at the end of a day 🙂

winter onyx Jun 3, 2020, 8:12 PM

#

lol

#

okay without .Complete the bug comes back

#

with burst turned on

#

so i sort of just need .Complete

storm ravine Jun 3, 2020, 8:13 PM

#

Yes

winter onyx Jun 3, 2020, 8:14 PM

#

so i will redo it now with .complete

#

hopefully it just won't be 4ms

#

to draw a line

#

my feeling is burst will help

storm ravine Jun 3, 2020, 8:16 PM

#

As it will give you immediate result for current frame and renderer will handle that changes and will render exact state in current frame and not from previous frame, but now with burst it will be very small

winter onyx Jun 3, 2020, 8:16 PM

#

yeah

#

alright i'm going to make myself another coffee

#

it works much better

you did it, you're today's hero

opaque ledge Jun 3, 2020, 9:38 PM

#

DSPGraph is pretty low level audio, you can still add class IComponentData on your entities and make systems that queries for it and run audio that you put into that component data, however you have to run the system with .WithoutBurst().Run() so on main thread without burst

some people have posted some snippets of stuff in the forum thread for it, could also look at the tests folder for the package.

Looking for any literature around proc gen for terrains in DOTS. I haven't touched DOTS in over a year hoping for it to have matured a lot and most of it's left my brain already, breaking terrain into components I can see a few that stand out (as an example)

TerrainData (perlin noise values, erosion math, other features)
TerrainMesh (building verts and tris)
TerrainTexture (building a texture based on things like TerrainData's height and features)

Is it preferable to have a single System looping over and running each of those jobs, or 3 systems running each in sequence? These systems won't actually do a whole lot when the game is running besides cull / instantiate new terrain chunks...

Does this design seem reasonable? Am I way off?

#

Is DOTS even perhaps overkill for this kind of thing? 🙂

cursive cosmos Jun 4, 2020, 1:37 AM

#

I mean, from what I have seen so far, I think most 3D games that are non-instanced (like open world) for sure should use DOTS. The difference is massive in performance. I also am growing very fond of how entities work and now when I got the "convert gameobject to entity" pattern down, it makes it pretty easy to make different kinda voxels.

I'm still nowhere near in making the terrain like Trove or Cube World. But I want to get there and I am also looking for reading material for voxel worlds. 😄

cursive cosmos Jun 4, 2020, 1:40 AM

#

yeah sorry, can't help you there, don't even know what that means.

turbid sundial Jun 4, 2020, 1:42 AM

#

Floating origin is when the world is "reset" to 0,0 when you move too far away from the "origin" point. An issue happens with floating point precision when you get into large distances (e.g. 100,000 units away) because a float can only contain a fixed length. Floating origin is the process of moving the entire game world back to 0,0 when you get too far to stop those issues from happening

#

(In Unreal it's called World Origin Rebasing)

#

But why would you need it to reset the origin?

turbid sundial Jun 4, 2020, 1:45 AM

#

because the larger a float gets, the less precision it can have
a really simplified example:

let's say a float can only contain 8 numbers, you can have

x: 1.0000000 - which means floats can have 7 decimals worth of precision, but you can only have 8 numbers, so when you get to
X: 1000000.0 - it can only have 1 point of precision

as a result, things like animations and movement become "jittery"

cursive cosmos Jun 4, 2020, 1:46 AM

#

And by saying float you mean the coordinates, or?

turbid sundial Jun 4, 2020, 1:47 AM

#

yeah, unity uses floats (the primitive type) for it's coordinate system

#

I think Unity uses 32bit floats

cursive cosmos Jun 4, 2020, 1:48 AM

#

huh, interesting, never thought of that problem, I mean, then you need a system that remembers the location for each entity...It would be pretty bad if your home coordinates reset...

turbid sundial Jun 4, 2020, 1:49 AM

#

Yeah in DOTS I'm not sure the best way to do it, in regular Unity* though - you can pretty much just move the whole world back (e.g. http://wiki.unity3d.com/index.php/Floating_Origin)

cursive cosmos Jun 4, 2020, 1:50 AM

#

interesting, would need to research this though.

#

I mean, I have barely understood how I should limit rendering.

#

So this is far off for me xD

turbid sundial Jun 4, 2020, 1:51 AM

#

I think if you're making any large-scale world (not just procedural), you have to consider floating origin - so it's something to remember

cursive cosmos Jun 4, 2020, 1:51 AM

#

for sure.

hollow sorrel Jun 4, 2020, 1:53 AM

#

@turbid sundial should be easy in DOTS
could just apply an offset to every Translation component same as you would normally, except ecs already allows you to easily fetch every Translation in the world

#

also with DOTS you actually have the ability to go with double precision if you want that, unlike normal unity

#

would prob go for origin shifting before considering that but still it's an option

turbid sundial Jun 4, 2020, 1:55 AM

#

Yeah I think there are some basic ways to approach it, but there are a lot of considerations

#

for example if you're not pure ECS, you'll have to match your shifting in both "worlds" (systems?)

#

and depending on how many entities you have, you probably want to put them all on the main thread so they all get shifted at the same time (and the world doesn't "stream" back)

#

not hard, but just some things to consider - I was mainly looking at Joachim's comment that they'd add new APIs to make floating origin easier.. assuming that hasn't progressed?

hollow sorrel Jun 4, 2020, 1:58 AM

#

yeah it's not built in already, dunno bout progress

#

what do you mean with world doesn't stream back?

#

oh because ecs and gameobject world

turbid sundial Jun 4, 2020, 1:58 AM

#

yeah, you'd want to make sure the shift all happens at the same time

#

one way to do that would be to use the separate worlds in ECS

#

ie. process the shift in world 2 in the background

hollow sorrel Jun 4, 2020, 2:01 AM

#

yea true it's a bit tricky if you're managing positions in both gameobject world and ecs world

#

if i were doing that i'd prob have an entity copy of every gameobject and make ecs world in charge of updating positions and sync it back to the gameobjects at end
so it'd be like
a monobehaviour wants to move -> add ecs moverequest component in ecs world or something similar -> when ecs runs, add moverequest to position -> end of ecs update, sync positions back to gameobject transforms

#

or something like that

#

dunno if there's pitfalls i'm missing here

#

so then ecs world can change translations and origin shift at will because the gameobject world is never directly manipulating positions

if I want to spawn stuff with ecb.
am I right to get the beginsimulationcommandbuffersystem?
or get get the endsimulation one?

halcyon plume Jun 4, 2020, 6:05 AM

You can spawn directly in manager

#

https://docs.unity3d.com/Packages/com.unity.entities@0.11/manual/entity_command_buffer.html

deft stump Jun 4, 2020, 6:31 AM

#

You can spawn directly in manager.
??? you can't use entity manager in a job though

turbid sundial Jun 4, 2020, 6:34 AM

#

You can use the command buffer, read the link he sent you

#

The first paragraph

The EntityCommandBuffer (ECB) class solves two important problems:
When you're in a job, you can't access the EntityManager.

deft stump Jun 4, 2020, 6:36 AM

#

I read the link. I'm using ecb.
I'm asking which ecb system should I use in spawning entities?
is it right that i use BeginSimulationEntityCommandBufferSystem instead of EndSimulationEntityCommandBufferSystem ?

tawdry tree Jun 4, 2020, 6:43 AM

#

Well, what are your needs?

#

If you want the entity to do anything this frame, spawn it in begin, otherwise it might be that you want end

halcyon plume Jun 4, 2020, 7:00 AM

#

??? you can't use entity manager in a job though
@deft stump i mean not in job. If you need to do it in job just ECB

i need instance of input system and send it to my ECS InputSystem

#

How i can do it?

#

lul

📎 unknown.png

opaque ledge Jun 4, 2020, 7:35 AM

#

How i use new input system is.. OnCreate method i create a instance of my input system script and enable necessary controllers and do bindings etc, then in OnUpdate method i read these input controllers and if controller is being pressed i schedule the job to move my player, if not i dont

halcyon plume Jun 4, 2020, 7:38 AM

#

how you get value?

#

Or what bindings do you use?

opaque ledge Jun 4, 2020, 7:40 AM

#

have you ever use new input system before ?

halcyon plume Jun 4, 2020, 7:41 AM

#

no. But i undestand how to use it in monoBehavior. Just subscribe on events and do actions like move etc

#

but dont undastand how to use in ECS

#

I could use some kind of buffer and write to it on an event

#

I just don’t think that calling Entities ForEach during the event will be correct

opaque ledge Jun 4, 2020, 7:48 AM

#

think of Systems like singleton Monobehaviours, OnCreate is Start method of a Monobehaviour

halcyon plume Jun 4, 2020, 7:49 AM

#

📎 unknown.png

#

i create it and its work

#

btw how to use it in forEach

opaque ledge Jun 4, 2020, 7:50 AM

#

yeah thats it basically

#

OnUpdate runs every frame, check your controller's values in OnUpdate

#

if a button is pressed then schedule a job that moves your player

#

if not, dont schedule it

halcyon plume Jun 4, 2020, 7:53 AM

#

like this?

#

📎 unknown.png

#

but unity said this

#

I think the best decision would be to make Singeltone

opaque ledge Jun 4, 2020, 7:55 AM

#

thats not how you read a value from a controller

#

check their manual or watch some tutorials on how to do it

halcyon plume Jun 4, 2020, 7:55 AM

#

But not sure if it will give access there

opaque ledge Jun 4, 2020, 7:55 AM

#

you read the value of a controller OUTSIDE of ForEach

halcyon plume Jun 4, 2020, 7:56 AM

#

Anyone could point out why this wouldn't work? (DOTS Physics)
https://pastebin.com/at9GK37P
This is in a ITriggerEventsJob, trying to find the point of contact between a projectile and a object (that might have a shield(trigger), hence have two colliders on same entity).
The code enters only the raycast when the projectile is hitting the base ground. I've added some padding to the raycast start end to see if there were some error.

halcyon plume Jun 4, 2020, 9:14 AM

just place script On-Screen and it will work

plain cloak Jun 4, 2020, 1:34 PM

#

@dull copper i see

dull copper Jun 4, 2020, 1:35 PM

#

that being said, 1.0 doesn't really mean much will change

#

rest of the DOTS ecosystem will not be production ready in years

#

so having core of it "released" doesn't make the full package feasible in production

#

Entities package itself is pretty solid already

plain cloak Jun 4, 2020, 1:36 PM

#

what do you mean by "not production ready"

dull copper Jun 4, 2020, 1:37 PM

#

quite literally that

plain cloak Jun 4, 2020, 1:37 PM

#

i thought you could use dots stack even now

#

for production

dull copper Jun 4, 2020, 1:37 PM

#

oh god no

#

only entities, burst and job system are somewhat solid now

#

rest is still experimental

plain cloak Jun 4, 2020, 1:38 PM

#

you could always go hybrid in places where it lacks, no?

dull copper Jun 4, 2020, 1:39 PM

#

hybrid renderer is flaky atm, dots physics doesn't evolve much and feels like is on some limbo, dots netcode got pushed yet another year (so they suggest it to be production ready only at some point next year - and will probably shift again), only unity knows how to use dots animation...

#

it's not realistic to expect full dots stack to be production ready this year at all, Unity officially targets 2022

#

and you gotta put year or two extra to that estimate

plain cloak Jun 4, 2020, 1:40 PM

#

true

#

in my current project, i use dots for all the calculation and state/gameplay stuff and use regular gameobjects to render, animate etc.

#

its a bit hacky but it works for now, was just wondering when i can go fully dots

#

but i guess that won't be here for a while

dull copper Jun 4, 2020, 1:44 PM

#

that's the safest setup atm

opaque ledge Jun 4, 2020, 1:44 PM

#

you cant go full dots right now

#

but if you know how to setup hybrid components then you can do everything that you can do with Monobehaviours

#

ui/audio/animation/Addressables etc.

#

by hybrid components i mean basically adding class IComponentData or AddComponentObject, and write systems that that queries for those

plain cloak Jun 4, 2020, 1:48 PM

#

i haven't used HybridComponents, is there any documentation on those or is it in development stage. I took a break for couple months so haven't caught up to all the updates yet

opaque ledge Jun 4, 2020, 1:49 PM

#

one of the unity staff said HybridComponents were meant for internal usage not for developers, but i guess it could be useable, idk, never tried

#

there was an example of it in ECSSampels

#

there's no guarantees it'll even stay around

#

workflows with experimental things are always subject to change

Well map itself procedural, but not infinite, you have static 1000x1000 area (just now, in game campaign it will be variable, in sandbox you can change size from predefined sizes like 400x400 800x800 1000x1000 etc)

i need the a component that store meshrenderer bounds , i tried to use worldrenderbounds but the AABB it generates it always axis-align to world so i thought about using localtoworld component and mesh bound on local so i read there is a component called RenderBounds but i dont know if the data i should give to generate it must be take from getComponent<render>().bounds or mesh

#

i think i have to improve my writing
the thing is that i need to get an local axis align AABB to be saved on components

#

i really apreciate if u could give me some advise with that 😉

opaque ledge Jun 4, 2020, 3:29 PM

#

hmm, never tried that so i dont know 😦

#

but there must be a way to convert world AABB to local AABB ?

undone torrent Jun 4, 2020, 3:31 PM

#

yeah probably but this is not exactly the matter i have, it is more that i doubt if i have to use the bounds of the render or mesh cause one comes on world and the other on local

opaque ledge Jun 4, 2020, 3:34 PM

#

tbh, sounds like you should use mesh bounds, because render bounds depend on camera right ? but yeah i dont know really, sorry

#

in API you can find what is the difference afaik

storm ravine Jun 4, 2020, 3:40 PM

For RenderBounds you should use mesh.bounds

i just solve it , finally i have to use mesh one; thanks for the help anyway , i hope i could help u in the future cause u are always helping me i really want to know enought for helping

#

yeah man

All other bounds will be generated automatically from this and required matrices, as World and Chunks bounds

So this is strange to me. I generated a mesh in dots (RenderMesh, RenderBounds, Translation, LocalToWorld) , simple 4 verts 2 tris, put it in the world. It seems to have some weird culling in the scene (and game) views if you get too close, or look at it directly. You might be thinking this is near-plane camera clipping, but I can put a standard cube gameobject in the same spot that won't clip the same way. Any thoughts?

#

HybridRenderer culling maybe? 😮

#

Ah, apparently it's known issues in the giant hybrid renderer v2 thread

cursive cosmos Jun 4, 2020, 7:03 PM

#

I've noticed my cubes sometimes do that.

#

I've got a fun problem, so I followed a tutorial for making a cupe with 3D perlin noise, and the big difference is that I spawn my cubes using DOTS with thanks to @storm ravine .
The fun thing about this is that my cube literally looks like it has more of a pixelated chaos going on than a wave shaped cave pattern which his has with the same underlying code.

So I'm wondering, does perlin get affected by the multithreaded code while spawning items causing this pattern or what could be the cause? Can post the System in a sec.

How do you get the perlin noise?

@turbid sundial it looks like your render bounds are incorrect

storm ravine Jun 4, 2020, 7:13 PM

#

Ah, apparently it's known issues in the giant hybrid renderer v2 thread
@turbid sundial There is no issue with culling. Just adding bounds do nothing (it will be 1 point culling, you can find thread on forum where I describe and show it) You should set bounds for render bounds from your mesh. You set it?

#

which his has with the same underlying code.

Perlin noise will be the same, not matter noise lib or Mathf

tawdry tree Jun 4, 2020, 7:24 PM

As an aside, with perlin noise you should mess with the scale if you want bigger caves, and thresholds to change amount of space/solid

#

As opposed to that pixelated mess

cursive cosmos Jun 4, 2020, 7:26 PM

#

float2 sample =  samplePoint * frequency + octaveOffsets[o];
float perlinValue = math.mad(noise.cnoise(sample), 0.5, 0.5);

While using this though, x/y/z wont affect the noise at all, so how would I go about sending that into the job for positioning?

#

is that instead of the noiseScale?

tawdry tree Jun 4, 2020, 7:27 PM

#

the samplepoint is the x,y,z

storm ravine Jun 4, 2020, 7:28 PM

#

perlin noise sample point is float2

tawdry tree Jun 4, 2020, 7:28 PM

So how do 3D with that?

#

skew with the Z, somehow? That'd make odd patterns

storm ravine Jun 4, 2020, 7:30 PM

cursive cosmos Jun 4, 2020, 7:43 PM

tawdry tree Jun 4, 2020, 7:43 PM

#

Also, from your sample code it seems like you generate a new cube each press of your generate button. It might be useful to make a way to change values (scale, threshold) at runtime and re-generate the cube when you press it. that way you can get a feel for what you get out of the procgen

cursive cosmos Jun 4, 2020, 7:44 PM

#

Nah, it's a cube per job

#

oh, you mean make it so it changes when values change

tawdry tree Jun 4, 2020, 7:44 PM

Well, that's one option

#

But right now you have

void OnUpdate() {
  if (Input.GetKeyDown(KeyCode.S))
    //Does not remove old generated stuff?
    //Generate new
    //...

cursive cosmos Jun 4, 2020, 7:46 PM

#

True, I could make a check so I can just spam S for them to re-render

tawdry tree Jun 4, 2020, 7:46 PM

#

Which is fine for just seeing how generating one chunk or whatever you call that works, but not so useful for experimenting with different values, since you need to exit play mode, change values (in code?), enter play mode, press S

#

That's a lot longer iteration time compared to "change values, press S"

#

And once you want to generate more chunks you can easily expand the system for that

cursive cosmos Jun 4, 2020, 7:48 PM

#

So what you linked is the bool if they should span a block...can try that

tawdry tree Jun 4, 2020, 7:48 PM

Short iteration time is exceptionally useful in experimentation 🙂

tawdry tree Jun 4, 2020, 7:55 PM

@cursive cosmos Scale "scales" the caves (true/false result).
Threshold is how "high" the resulting number must be to return true, or put differently, how rare the procgen is.
I recommend setting the threshold fairly high for initial testing (0.7? it's 0-1 BTW), and when you have more air that blocks, scale up slowly (from 1 to 1.2 then 1.5, 1.7, 2, 2.5, etc) to see how that works

I'm guessing you cant and need to do some sort of math after the noise so it works like having a seed?

perlin nosie isn't seeded

The "seed" is the position, so if you want a "seed" you use some arbitrary large offset

@warm panther For the second half of that, I assume you use Jovian.Components.Weapons.Projectile in the job.
As for how to do that, the job wants ExportPhysicsWorld:ExportDynamicBodiesJob as a job dependency... though I'm not sure how to accomplish that

@tawdry tree Yeah that's what I read out of it myself.

if (noiseVal > 0.5f) and this should be replaced to your threshold

cursive cosmos Jun 4, 2020, 8:21 PM

#

what was your values on scale and frequency @storm ravine ?

storm ravine Jun 4, 2020, 8:21 PM

#

15 0.9

tawdry tree Jun 4, 2020, 8:22 PM

#

Why the math.mad operation, by the way?

storm ravine Jun 4, 2020, 8:22 PM

#

@cursive cosmos threshold should be 0-1 as noise return you 0-1 in current implementation and frequency <= 1, frequency can be > 1 but then you should change threshold as they related

tawdry tree Jun 4, 2020, 8:23 PM

#

Noise should IMO return a normalized 0-1 value for easy of reasoning

It gets better:

nvalidOperationException: The previously scheduled job CollisionEventSystemJob reads from the Unity.Collections.NativeArray`1[Unity.Physics.Velocity] CollisionEventSystemJob.EventReader.m_InputVelocities. You are trying to schedule a new job Solver:ParallelApplyGravityAndCopyInputVelocitiesJob, which writes to the same Unity.Collections.NativeArray`1[Unity.Physics.Velocity] (via ParallelApplyGravityAndCopyInputVelocitiesJob.InputVelocities). To guarantee safety, you must include CollisionEventSystemJob as a dependency of the newly

This is what my simple CollisionEventSystem gets when it just get scheduled, without using any ComponentData. this is practically 1:1 copy from the samples I found on the forum.

Why the math.mad operation, by the way?
@tawdry tree as it will be reinterpreted in assembly code to 2 add instructions instead of one add and one mul

tawdry tree Jun 4, 2020, 8:23 PM

#

Yeah, but why are you doing multiply and add to begin with?

warm panther Jun 4, 2020, 8:23 PM

#

[UpdateAfter(typeof(EndFramePhysicsSystem))] by the way

tawdry tree Jun 4, 2020, 8:24 PM

Does cnoise return -1 to 1?

Oh my god it works.

Wee, progress!

storm ravine Jun 4, 2020, 8:24 PM

yes it [-1:1]

tawdry tree Jun 4, 2020, 8:24 PM

#

Ahh

#

Assumed that was the case, but the docs are still sparse..

cursive cosmos Jun 4, 2020, 8:25 PM

#

@storm ravine you are a noise genius.

tawdry tree Jun 4, 2020, 8:25 PM

#

Sugar, now you got a good cave generator! For a floating island generator, increase the threshold a bit (or lower, depending on which implementation you use)

cursive cosmos Jun 4, 2020, 8:27 PM

#

Now I need to figure out landscape math and how to know if it should be grass and dirt and so on.

#

But this is a good start

ocean tundra Jun 4, 2020, 8:27 PM

#

looks great

cursive cosmos Jun 4, 2020, 8:29 PM

#

wait, can you even make system variables public for change?

#

do you have to place the systems on an empty game object and such?

tawdry tree Jun 4, 2020, 8:29 PM

#

You can make them public, yeah

#

Might not be a good idea, it is certainly easy to go against the best practices that way, but for experimentation, sure

#

No, systems exists in the entity manager, mostly

cursive cosmos Jun 4, 2020, 8:30 PM

#

At least during experimentation phases, yeah

storm ravine Jun 4, 2020, 8:31 PM

#

systems exists in player loop

tawdry tree Jun 4, 2020, 8:31 PM

#

If you want to be able to tweak them "live" you could make a monobehavior with the appropriate settings, and in the MB's update, set some public static vriables to the same. The system could then access those (outside the job)

#

That's a really dumb and naive way, but should work?

#

A more DOTS-y way is to use singletoncomponents or entities or whatever replaced them

#

Still need to get the values into some code you control, tho

cursive cosmos Jun 4, 2020, 8:32 PM

#

I'm just afraid to spawn duplicates and such.

#

like, pulling a slider and spawning a million of the entities would be bad

tawdry tree Jun 4, 2020, 8:33 PM

#

Hmm, the live thingy with subscenes could maybe do it? Haven't touched those yet, so wouldn't know how

#

If you did what I said, you would still need to press the "generate" button to generate

#

Oh, and you should add something to find and delete all the existing entities first, probably...

cursive cosmos Jun 4, 2020, 8:34 PM

#

yeah, which would not be bad, but I still need to grasp all my entities and remove them, dunno how to grab them all though unless I should save them in some list and remove then one by one in jobs

tawdry tree Jun 4, 2020, 8:35 PM

#

entities.WithAll<your_tag_component> and entitymanager.... use intellsense and look for dleeting entities?

cursive cosmos Jun 4, 2020, 8:36 PM

#

Oh have not even made a tag component yet, should probably fix that

tawdry tree Jun 4, 2020, 8:36 PM

#

You want at least some way to fetch the blocks, yeah 😛

#

Alas, I have to be off, feeling the sleepy seeping in.
Good luck!

cursive cosmos Jun 4, 2020, 8:37 PM

Who connects UI and ECS? As I understand it, is there any system like UISystem and the displayValue component which is on something? or how? what about the events?

warm panther Jun 4, 2020, 9:09 PM

#

Wow, unity crashes hard when you leave a stray Debug.log in a burstcompile job. what garbage.

#

At least a warning would be kind.

#

I mean we can barely debug jobs as it is, at least printf debugging needs to be available at all times.

I'm this close to writing something that renders a native textbuffer to stdout or something. like the matrix.

mystic mountain Jun 4, 2020, 9:11 PM

#

Doesn't it give warning if you don't burst compile?

warm panther Jun 4, 2020, 9:13 PM

#

nope

#

also, ever since I put this system in, Enter Play Mode takes ~20 seconds. I wonder what's up with that.

#

Well I was able to successfully get a collision to work, but as soon as I try to read any Componentdata like my Projectile tag, it doesn't work.

#

InvalidOperationException: The previously scheduled job LocalToParentSystem:UpdateHierarchy reads from the ComponentDataFromEntity<Jovian.Components.Weapons.Projectile> UpdateHierarchy.safety. You are trying to schedule a new job CollisionEventSystemJob, which writes to the same ComponentDataFromEntity<Jovian.Components.Weapons.Projectile> (via CollisionEventSystemJob.UserJobData.ProjectileData). To guarantee safety, you must include LocalToParentSystem:UpdateHierarchy as a dependency of the newly scheduled job.```

#

Same old

halcyon plume Jun 4, 2020, 9:27 PM

#

So... What about UI in ecs?

warm panther Jun 4, 2020, 9:31 PM

#

I export my ECS data to a classic UI as needed. Some of it, yes, via singletons, others through messages much like what Codemonkey demoed a while back.

turbid sundial Jun 4, 2020, 9:47 PM

#

So I'm creating a NativeArray<float3> to represent all of the positions of terrain chunks I've generated. Obviously, this fills them all out with zeroed float3s, and when I check whether or not a chunk exists at that position - it always will, so it'll never be generated 😮 I guess a simple fix would be to just put the terrain at 1f on Y, but any other thoughts?

halcyon plume Jun 4, 2020, 9:49 PM

@warm panther can u send video link ? And example of your code

Projectile is literally this.

#

It is not used in any of my systems (however it is added by an authoring component)

#

Ah oops.

I thought you were gonna help me with my issue 😄
