Official DOTS Sample

It seems Debugging and maybe Burst 'checks' don't save well.. As I know the ONLY thing I do, is go in and un-check them a trillion times a day.

 

Any way to create terrain shader which is support the hybrid renderer? my terrains not showing at all,

 

If you do a search for "Terrain" in your packages, you will find a HDTerrain material that you can apply to the Terrain and it will render as normal

Cheers
-Micah

 

I using the HDterrain shader and the terrain is not rendering well both in editor and build, this is why i'm asked if there is a way to create a terrain shader which has an option to support hybrid render as the other shaders, i'm didn't find a way to create terrain shader graph.

i'm added the terrain to a subscene and its only shows if i'm edit the scene under the sub scene script, after i'm closing the scene, only trees and grasses are showing and terrain is gone.

 

I have my terrain in the main scene, as a sub-scene converts everything to entities.

So in the attached picture, I have my:
1. Terrain made by MapMagic in the Main Scene (whitebox_newmeshtest).
so its not converted to any entity in a sub scene.
2. Veg Studio, which manages Trees and Fulstrum Culling as entities in my main scene as well, so its not converted to any entity in a sub scene.
3. The Terrain doesnt collide with the player right now naturally, so I exported the terrain to a mesh, and added that mesh to a sub-scene (020_environment), so that its converted at run time and works for collisions.
4. Trees, Map Magic generates the placement of the trees and I also used it to generate colliders for the trees, by placing the gameobjects id later converted via a subscene. I then took the tree collider-objects (not renders) off the terrain, and dragged them into the sub-scene environment.

Now I can see the terrain, use the terrain textures per normal, and shoot/run on top of it.
I can also see trees, and collide/shoot at them.

All running at better than 60fps, in editor and in build, at 4k. With 2 clients connected.

Ill be posting a video summary of this, and ill put the link here as well.
<Below is my dev Log 3, I tried to cover this>

 

Moving Terrain to the main scene did the trick thanks!

 

Any way to create similar build like the editor mode so in the build its starting a server +client?

 

The "Play" Button does start a Server and Client, within the editor. You can also access the "assets/Build" folder and build stand-alone Server and Client applications to do full stand alone testing. You can also access the "A2" or 'Multiplayer' menus to launch a mix of client or server running editors, and external stand alone apps, together. So you can see what happens on just the server, within the editor, as example.

 

Thats okay, i can do builds, server and client, but i would like to create a build which is similar create server and client at the same time and you can play as its in the editor when the multiplayer settings are Client&Server. its could be useful in 1v1 or for smaller matches, so one of the players are became the host.

 

I have been trying to explore the DOTS sample by making some theoretically simple changes to the game to see what happens. One of the things I've tried to do is add an alternative weapon - as a first step towards this I copied Weapon_Terraformer to Weapon_Foo and switched Hero_Terraformer to give the hero the new weapon instead of the old one. I adjusted a few controls and such on Weapon_Foo just to make it clear whether I had successfully swapped the weapon. I also then regenerated all the appropriate ghost code.

This has resulted in some weirdness, and while I've found a workaround, it feels hacky and is probably not the intent so I'm wondering whether there's a better approach someone can point me to.

Specifically, even though the Hero_Terraformer specifies the hero should get a Weapon_Foo (and they do on the server), on the client the hero instead always gets the Weapon_Terraformer. As far as I can tell, this is because the two weapons are very similar to the point that the system is using the same Archetype. What this means is that when FindSerializer() gets called on the GhostSerializerCollection, both types of weapon would return true on the CanSerialize() check and therefore the first one in the list will be used for both types of weapons, which happens to be Weapon_Terraformer in my case. Looking at the docs for NetCode and Ghosts this seems to be known and/or somewhat intentional. But since I've got two different prefabs and no way to choose between them, information seems to be being lost in this transfer. In my case the thing I noticed was that the activation buttons were always using the Weapon_Terraformer's activation buttons but this would seem likely to be the case for other things, such as if I'd tied the new weapon to a different-looking Part, I'd expect to get the wrong one.

My workaround here is to add a special marker component to each type of weapon so that they're different and thus end up having separate EntityArchetypes, but this is a bunch of annoying extra empty marker classes and feels hacky, so I'm thinking is not the preferred approach here.

Am I thinking about this totally wrong? Is there only meant to be one Weapon prefab/archetype and any differences between those weapons need to be sent across the wire to the client? That would seem to be sending unnecessary network traffic about something the client could just know about, but maybe that's not as big a deal as I'm thinking since it's only at creation time? (Although I also think if that's the case then the way the sample has ability activation buttons setup is not properly transmitting since those didn't seem to get reflected on the client.)

As a slight aside - if you want a somewhat simpler version of this, you can get a similar effect with the NetCube project by duplicating the Cube as Sphere, swapping out its render mesh, and regenerating all the ghost code. If you put the sphere first in the GhostCollection, you will then see that even though the server is still spawning you as a cube, on the client, you are a sphere because that was first in the GhostCollection's list and the change to the render mesh did not affect the Archetype.

 

The answer to your question is both Yes and No. The DOTS Sample is clearly just a sample and as such limited in its functionality. It was built for a specific use case, and that use case was to get a single weapon working. So what you are doing is correct in the current context and also probably recommended, though there are other ways to achieve it.
A weapon can be an EntityArchetype, the deserialized version of that Archetype can be an instance of a weapon.
How that weapon looks can be a value on that weapon.

So I guess what I am saying is you can either think of:
1. Every weapon type is its own Archetype
2. A weapon ( firearm ) is an Archetype, and its mutable characteristics are values on that archetypes components such that when you deserialize you can find the correct prefab to spawn or mutate.

There may be other ways to view the relationship but thats how I see it from examining the code and my rudimentary knowledge of ECS

 

I just downloaded the project, selected the Whitebox_Arena_A/Whitebox_Arena_A.unity scene and hit play
The FPS is abysmal, the profiler states that a PlayerLoop takes 125ms, 41.47ms of those are wasted on WaitForJobGroupID. What kinds of files I need to supply to troubleshoot this?

 

Joachim gave a pretty good explanation on editor performance:

 

After disabling everything above, it still would only run at 55~ fps, where only 2.4 ms were from the render thread according to the stat window. Considering how much DOTS is supposed to speed things up, I still think there is something wrong with my configurations, but I guess I will just wait for more improvements before I start developing with the netcode thingy

 

The underlying sample runs well, even with the server code set to single core as earlier pointed out. I was seeing 60fps+ at 4k, with veg studio and tons of vegetation running on top of the sample. Best performance will not be seen in the editor.

Be sure to turn off burst compile, and wait for all the compiles to be done in play mode. But still, within the editor, you will be hard pressed to see about 60 fps. Also, what are you judging fps against? I took time.deltatime of the last 2 frames, divide by 2, and then took that and saw how many I can fit into 1 second. that is the fps displayed on this video of the modded dots sample:

But this is just self testing, were you load testing with multiple clients?

PC is a Intel i7 8700k @ 4.5Ghz (6 core)
32 GB 4133Mhz DDR4
Raid0 M2 Drives (3.5GB read, 1.5GB write)
Zotec AMp Extream 1080TI 11GB
4k@60hz, 3440x1440@120hz, 1080@60hz
Asrock Z370 E4 Mobo

 

Right now the DOTS Sample is configured to run everything in a single threaded manner (both server and client are running on one thread) -- the client and server compute times are stacked in the editor. If you compile a server executable and a client executable each will run in their own thread and you will see much better performance.

 

If you mean 'how did you measure fps?', the play mode stat window.

Glad to know that most if not all performance issues are Editor time only, it means I can start messing with it

 

@AggressiveMastery
Thanks for the videos. Accelerates getting into the DOTSample a lot.
Please add again a car controler like you did in your fps sample tests.)
Do you think it is already working to have an standard car phsysics controler or the official RaycastCar demo from the UnityPhysicsSamples
https://github.com/Unity-Technologies/EntityComponentSystemSamples/tree/master/UnityPhysicsSamples/Assets/Demos/6. Use Cases/RaycastCar
as movable platform?

 

Howdy Keeponshading!!

This sample is made with DOTS Physics, so we will need to call against physics in DOTS. Which I haven't done, but it will be a distance cast vs entity transforms. Just done with a scheduler every frame.

So you could pull in the old car scrips, but they are mono-develop (single threaded), and not DOTS(multi-threaded : OVER SIMPLIFICATION GUYS.) So you are then placing the car scripts, as mono scrips, as huge road blocks to each frame. Basically destroying the beauty of DOTS. Unless you have put the DOTS Multiplayer Sample aspect as all you are using in this sample

It will be best, and what I will be doing, but not for a few months... is making a DOTS car controller, as that will be vital to multiplayer. It may be as simple as restricting player movements, so they act as a car. But I want a moving body, you can walk around on with other players. Like the friggin DOTS sample of the FPS sample, never released. /pff

So it wont be, in any way, as easy as it was in the FPS sample. Unless you abandon DOTS, then ... maybe. Just attach the move script to your car, and find a way to trigger it with dots. And dual your colliders, meaning have one for the old car script physics, and dots, basically bastardizing the physics between dots and old units.

Just talking theory, and I look forward to showing it in action, some future video

I think it would be fairly easy honestly. The most complex aspect of this sample seems to be the new animation and any code that fills in the gaps of missing features. Ill look into the code again shortly and see if i can point out some areas where the raycast car sample would be ported and merged.

 

One thing that irks me about the DOTS Sample is that there seems to be the inability to calculate offsets easily. For instance I am unsure how the creators efficiently determined IK offsets.

 

Hey! I was able to get Visual Scripting for DOTS working with the sample. By changing the error about time to reference UnityEngine.Time, and by moving the Visual Script Package folder out of the cache folder and into the package folder so that the modification does not get over-written each reload of the editor. Its great to see class/struct from the overall sample there. ... https://forum.unity.com/threads/dot...-experimental-drop.795807/page-2#post-5408067

 

Hello!

Anyone figoured out which script are starting the multiplayer?
Somehow i would like to find out the how the systems are starting, so far which is clear thats the game.cs but seem "Network client" are intitializing automatically, for now(for testing) i would like to completly turn off the multiplayer part but seems i can't find how this all are starting, any ideas?(there is no documentation at all also seems already dead project again?)

Thanks!

 

Bootstrapper, check out the "build folder" and you can see in the diffrent build scripts what the default scenes loaded are.

Within the boot strapper you will find the game kickoff scripts.

Since this is DOTS , and a DOTS Sample Project, a lot of the 'work' is done via jobs and systems. So you need to understand how DOTS executes per frame, to get a full understand whats being done.

 

Bootstarper scene are only contains a prefab with the Game.cs and than a lot of thing happening(automatically in the backdround especially in the editor.)..

 

Correct, DOTS has Systems running automatically, which then take action on any data that needs to be modified. So all the DOTS Systems, I believe, start running by default. So looking for those systems, could que you into them. By restricting what entities come up in your queries by those systems, you reduce you workloads (the systems always run, but without any work to do, are very low overhead.) So its not all happening in one game.cs, its happening through all the systems as well. Aka the need to understand DOTS.

So Game.cs runs every frame, and some other mono scripts are also running every frame.
Additionally, you have several DOTS systems running as well, looking each frame for work, and doing it (I believe all in a single core .run now from above posts).

The 'Engine' then, is a few Game.cs type things, but mostly DOTS systems looking for work each frame. Which is nice, as it frees you up to write your own DOTS or mono scripts for the other cores on the system, or switch this to .schedule? and co-mingle the jobs.

 

The Editor is also running a Client and Server version of the code, so you have options to view scrips/jobs/entities for all those worlds. aka ya lot is happening in the editor, you need to filter it down to see specifics.

 

Hello, I have tried to open DOTS Sample with Unity 2019.3.0f6 but Unity freeze when loading package manager "Resolving Packages.."

 

I fixed this by change the version of the animator package to this "com.unity.animation": "0.3.0-preview.7" and then back

 

Tested it, didn't work for me.

 

I'd recommend making a fresh install of the DOTS sample, then re-opening it.

It doesn't freeze up like that for me.

You may also try to reset the package manager, but then you would need to manually selected the required packages which may be a pain...

Additionally, I am running Windows 10 64bit, fyi.

Good Luck
Micah

 

Thanks, I don't think it's related to the DOTS Sample project because I can't even install the entity package in an empty project, I think it's either related to my widows username having a space in the middle or some Visual Studio packages.

 

I've been trying to target Android with the DOTS Sample project and I can get as far as replacing all HDRP based shaders with URP ones. However when building for android i believe subscenes and weakassetreferences/prefab registry assets seem to be missing from the apk, since only the 2d UI overlay renders over a black screen. In the logs, there is an error when AnimSourceController tries to CreateEntity, which thinks the guid is all 0's.

I noticed that the version 0.4.0 of the entities package contains build pipeline code which was later separated out into the platforms packages in 0.6.0 . It isn't until version 0.2.0 of the android platform package where it contains a hybrid build pipeline that includes the step to include the assets for android.

While i want to use 0.6.0, it also makes some breaking API changes such as World.Active being removed or returning a readonly list, both of which causes issues with the current version of the unity net package (0.2.0 - 0.4.0).

When might we expect an update on the dots sample project and those packages?

Edit:
It seems for the time being Entities version 0.5.0 added in android hybrid build support and doesn't make api changes that break net 0.2.0 (also doesn't require the new individual build platform packages)
Though the same error still pops up

Edit 2:
I am logging out the entity lookup as such:

Code (CSharp):

1. public static Entity FindEntityPrefab(EntityManager entityManager, WeakAssetReference assetGuid)
2.     {
3.         GameDebug.LogWarning("FindEntityPrefab: " + assetGuid.ToGuidStr());
4.         var entity = GetRegistryEntity(entityManager);
5.         if(entity == Entity.Null)
6.             return Entity.Null;
7.  
8.  
9.         var entries = entityManager.GetBuffer<PrefabAssetRegistry.Entry>(entity);
10.         for (int i = 0; i < entries.Length;i++)
11.         {
12.             GameDebug.LogWarning("FindEntityPrefab --> iterating: " + entries[i].Reference.ToGuidStr());
13.             if (entries[i].Reference.Equals(assetGuid))
14.                 return entries[i].EntityPrefab;
15.         }
16.         GameDebug.LogWarning("FindEntityPrefab Not Found: " + assetGuid.ToGuidStr());
17.  
18.         return Entity.Null;
19.     }

Which now yields

So it seems somehow

settings.RootAnimSource

is losing the asset guid when built for android which is bizarre since i get

0: Convert DotsAnimStateController:Char_Terraformer (AnimSourceControllerAuthoring) 8df330aa5f962b94590d6c4477944a

when logging out the editor prefab conversion for the

AnimSourceControllerAuthoring 

script

Code (CSharp):

1.  
2.  
3.     public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
4.     {
5.         GameDebug.Log(string.Format("Convert DotsAnimStateController:{0} {1}", this, AnimSourceRoot.ToGuidStr()));
6.  
7.         var settings = AnimSourceController.Settings.Default;
8.         settings.RootAnimSource = AnimSourceRoot;
9.         dstManager.AddComponentData(entity, settings);
10. ...

Could the prefab losing the value and becoming null be related to this issue?
https://issuetracker.unity3d.com/is...re-lost-when-modifying-prefab?page=1#comments
As a really bad hack I've hardcoded the guid reference lookup:

Code (CSharp):

1.                 // Create root animsource
2.                 var settings = EntityManager.GetComponentData<Settings>(entity);
3.                 if (!settings.RootAnimSource.IsSet())
4.                 {
5.                     GameDebug.LogWarning("Could not retrieve default asset reference, RootAnimSource, hardcoding to 8df330aa5f962b94590d6c4477944a8b");
6.                     settings.RootAnimSource = new WeakAssetReference("8df330aa5f962b94590d6c4477944a8b");
7.                 }
8.                 var rootAnimSourceEntity = PrefabAssetManager.CreateEntity(EntityManager, settings.RootAnimSource);

At any rate it can barely run on Android now, if i turn off burst compilation. It seems it's erroring out on many null references pertaining to rigging. It only gets maybe around 15-20fps

 

I noticed that the project says you guys use the new DOTS based physics package. From what I can tell the game's framerate isn't tied to the speed of players (who I assume are rigidbody based), how did you solve the framerate related physics update issues that currently plague the physics package?

Thanks in advance

 

It's because they use the DOTS NetCode which runs (Server/Client)SimulationSystemGroup at a fixed rate. You can see the logic for this in the actual SystemGroup classes to only call OnUpdate for certain conditions.

With the latest release of

"com.unity.netcode": "0.1.0-preview.6",

I've been able to update to the latest platforms.

After much code refactoring to use the new netcode beginsend/endsend api, transport's writer/reader ref instead of context, and buildconfiguration types (and World.Active) (required modifying ghost template, and regenerating every ghost)
It seems it finally does build for Android correctly by including the prefab rig assets. (maybe something to do with one update fixing subscenes and gameobjects? not sure)
Though i may have broken the thinclients as now they're processing player inputs as well (could be due to how it uses world.active)

It was only made possible through judicious use of deleting the library folder and all generated csproj/sln files after each upgrade or major script structure change.. Oh yes for some reason unity.build namespace could not be referenced by the build scripts... so i ended up having to add asmdefs to the main asset scripts, including separated ones for editor and tests folders needing explicit editor platform reference and nunit reference.

Ah yes and this is working on 2019.3.3f1 (which apparently was just upgraded on the DOTSSample github page but with no actual changes to the project)

 

Hello!
There are 16 such errors in "Entities@0.6.0", how to fix them?

Library/PackageCache/com.unity.entities@0.6.0-preview.24/Unity.Entities/Types/FastEquality.cs(297,42): error CS1061: 'UnsafeAppendBuffer' does not contain a definition for 'Size' and no accessible extension method 'Size' accepting a first argument of type 'UnsafeAppendBuffer' could be found (are you missing a using directive or an assembly reference?)

 

The key solution was the package:
"com.unity.collections": "0.5.2-preview.8".

Aren't the necessary dependencies installed when installing the package?

I also had to add asm def, it didn't work without it, it seems.

Also, I had to replace the IBuildCompilation interface with another one ( I don 't remember which one ), and I don't remember which class I did it in.

I didn 't delete the Library folder.

Personally, I need to change a lot of code to run the project)

 

Only if the dependency isn't already forced to specific version in the manifest / package manager. This is the reason why in general you should avoid installing packages yourself which you know will be installed via dependency anyway.

 

Are there any docs on how the sample works?
There are lots of "hacky" stuff going on in the sample that I can't figure out why they are there.

 

System code spread anywhere makes it very difficult to understand logic, put anything in System Update and ignore the logic sequence may not be a good idea. kinda weird~

 

I seem to have this issue where if I leave a server running for a long time, somewhere over 8 or so hours and a client connects and loads into the map, it'll freeze for almost half a minute or more, until it times out from the server... Any idea why this is happening? Could this be due to somehow simulating all the game ticks the server is up to?

 

@eatbuckshot could you share your diff about the Netcode update?

 

I manually copied the diff from some of our commits here

Unfortuantely github has a limit on the number of files, so it's in two gists

Thank you, this was very helpful.

Did you happen to come across the following error?

Updated the DOTS Sample project to the latest yesterday and still can't run it on Unity 2019.3.6.
For some reason the scene start but I can't move anything.

 

Me every time dotssample gets updated:

clicks to see what changed:




I'm confused about image shown on the latest roadmap video:

Megacity lacks basic functionalities like physics, you can simply fly through all buildings
FPS Sample is outdated and probably buggy as on github there's 70+ issues

With this being said I can't see how they are Released. I'd call them - Abandoned.

Next DOTS Sample:
If you check github commits you can see that in 4 months it got only one small update. Code frequency graph shows it better:

I'm not sure what "Prerelease focus" means. Does Unity still work on this project or it's joining The Abandoned Group? Why can't we see changes every week/month, contribute with pull requests, talk about used patterns etc? That's kind of what Unreal does with their engine itself.

Hope to see that next roadmap live stream happening in few days will clear it up.

 

Nice...Importing the package, my unity is stuck on resolving packages for hours... Any ideas on what could be the problem. i am using a higer version of unity by the way.

 

I had the same issue. What worked for me was removing the FBX package from the manifest and adding it back via the Package Manager.
