Official DOTS Development Status And Next Milestones - March 2022

I'm having a hard time finding details about ISystem, what it's for and why I need it - I am super interested though if you would share any links to reading more about it or tell me, thanks!

 

From profiler, my project super slow performance issue is caused by official dots packages. These systems should migrate to ISystem first and try to make it as fast as possible. The bottleneck mainly coming from Entities and dots physics packages.

I know u can just choose those platform specific directly from player settings but without platform specific components I need to manually do it myself every time when I need setup something to do different builds. With this platform specific components I can just press build at build config to get the build I want right away. Another reason to do that is I believe there are some platform specific setting at Build Settings doesn't work really well. It requires platform specific components to support it well when building dots project. For NDA platforms I think u can create another NDA platform package just like how graphics team does to strip NDA platforms out of general platforms.


One more question. For 1.0 release, will it have auto API upgrade tool to auto upgrade API as much as possible? From what I see, 1.0 release will change quite a lot of APIs. One of the most commonly used APIs like Entities.ForEach/WithAll at 0.5x release will change to something else at 1.0 release. I have too many systems and it's too hard to migrate every system manually.

 

Are u referring to menu DOTS - Entities Journaling? If yes then I didn't enable entities journaling or it's bug that it enables accidentally? I check the player setting there's no ENABLE_PROFILER define at scripting define symbol. It just at there according to profiler.

For dots physics, I'm curious is that this super convenient API still a thing at 1.0 release? I dun really want to write lots of boilerplate code anymore just to do simple collision detection. Another thing is it seems like until now collision/trigger detection still can't run on main thread. Any plan to support it to better support mobile platform very slow at using job system? Or can I expect bursted job system can solve slow performance issue at mobile platform?

Seems like it's caused by dots netcode package. It will just enable by default no matter what and can't disable it. Can u make sure it will be fixed at 0.51 release? But for now I would like to get unofficial fix first.

Another thing I want to feedback is enter play mode is super long at dots netcode project even enter play mode options is enabled. It seems when project getting complex it will start to become very slow to enter play mode. Will it improve significantly at 22.[2|3]?

At least make sure the following 2 issues will be fixed at 0.51 release and beyond. Another thing is I think try not to change too much for Platform package. I still backport old Platform Android package.

hi, what is the status of work of entities in 2021.3 LTS ? I dont see the package in the packages manager

Is the project still going ? March 2022 is past also, is there a new time frame for it ?

Thanks

 

You should refer to the first post of this thread.

 

@elliotc-unity After I further dig into the issue, I found it's caused by OOP land scene. Hopefully subscene can fully solve this slow enter play mode issue at editor.

Sorry I still have questions want to ask.
1) Will mega-chunks & tiny chunks feature release at dots 1.0 release? Like mega chunk is 256kb of memory for each chunk and tiny chunk is 512 bytes of memory for each chunk.
2) Will dots addressable support instantiate oop land game object? I think it needs to support instantiate oop land game object since game object is still require at dots project.

Hello,

May will end soon. Is there any news about entities version 0.51? It's really bad that version 0.50 is not supported on Unity 2021 LTS. Our studio needs this depensicity for the new physics package.

Thanks for updating

 

Please be patient. Equally it may be tomorrow, or next year. No one will tell you, until is released.

You should not be designing game around future packages. If packages keep delaying, or get canceld and your project fail, it is all on you.

 

Did you know that entities is now part of many packages in Unity, Such as Unity physics, Havok physics, and... so kinda too late for canceling something like this.

 

Everything depending on it is also in preview. Equally unknowable futures. What Antypodish said applies to those as well.

 

I know everything depending on it is also in preview. I mean the chance of canceling something like this is low because many preview packages depend on it. if we talking about "Relay Allocations" or "Lobby" that's true, because none of the packages depend on these, they are there for their selfs.

 

It is being worked on. I think the current problem was thinking about having it separate from 2020 LTS. So I do not think it will be compatible also with 2021 and 2020. Regardless, it shows it's not trivial. Probably some breaking change is possible.

 

But the Jobs System is still marked as a pre release package...

 

That's the jobs package not the job system.
This package adds extra jobs and features but you do not need the package to use the job system.
IJob and IJobFor ship with the unity editor and can be used without this package.

 

I think Unity should have named the package differently to make it clear that it's just an additional feature pack, and not the job system itself. Some people think the job system isn't final, I've read that several times now.

 

Ok, Thanks for explaining that.

 

Apologies if this has been asked and answered. As we are nearing the end of Q2 2022 has there been any updates on this? Is this update still scheduled for release this month?

 

Lovely! Is the main 1.0 release possible before 2023? I ask because the target is 2022.2 (unless of course 0.51 works with 2022.2 as well.. hopeful?)

 

Thanks, that's good enough for me - the dude abides.

 

I’ll just voice my desire for some radioactive preview releases in the space between 51 and 1.0

 

https://docs.unity3d.com/Packages/com.unity.entities@0.51/changelog/CHANGELOG.html

Seems like its out guys!

 

Think that's old? May 4th?

 

Not sure how their naming works but it appeared today as it is the 0.51 package we've been waiting for.

 

https://docs.unity3d.com/Packages/com.unity.entities@0.51/manual/index.html

Seems the package is now available. Checked my unity project and it says there's an update. So I guess it's now official.

 

So is DOTS compatible with Unity 2021 now?

 

Yes, at least according to docs https://docs.unity3d.com/Packages/com.unity.entities@0.51/manual/install_setup.html

 

Depends on what you mean by compatible.

I have null refs on build that weren't there before on 0.17. So for me the 0.51 is actually working worse.
*sad noises

edit. after few days of fixing and finding solutions. The new update seems to be working

 

Hi everyone, sorry for the small delay between package release and communication. Let's continue our discussion in the up-to-date roadmap post over here!
