ECS WebGL support

Unity Engine
,
1

Is it supported at the moment? Using 2019.3.0f3
Right now, the webgl build is crashing at startup.
I have the below relatively simple system. If you look inside CalculateConnectionsJob, I have a one liner there

if(!m_dirtySlotTagType.Exists(entity))
                {
                    m_ecb.AddComponent(index, entity, new DirtySlotConnectionsTag());
                }

If I comment the above, it’s working. Full code and error log from the browser below.

And the log for the “Internal: JobTempAlloc has allocations that are more than 4 frames old…” entry, when I expand it in the browser console, seems like a call stack

8c296607-a449-4e89-a3e2-63fac16e648e:3439 Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak

Somewhat false alarm, I think below is a memory leak, but not the cause. I disabled the audio listener in the scene on my camera and the issue below disappeared. So i’m still looking for the real cause

Old comment:
Could it have something to do with the way Unity implements Audio in WebGL? That seems to be a leak, if I’m reading Chrome profiler correctly. I’m new with profiling in browser.

Hi, this issue is blocking my company moving forward with WebGL, submitted a bug report as well but no reply. Can someone please suggest the way forward?

As I understand it now, project TIny may be the best current approach to use dots in the browser. Since it’s at least their main focus. Is there a possibility for you to experiment with that? There’s a dedicated Tiny forum as well for you to post in.

Thanks for the reply, but unless I misunderstand, Tiny is 2D only

And 3D look at tiny race sample.

Any updates on this please? Is the WebGL target supported in ECS Hybrid (with gameobjects)?

In the package manager there’s a DOTS build option for webgl so it looks like this is at least intended to be possible now.

I have a scene with some GameObjects with ConvertToEntity. Basic stuff, some cubes and some spheres. The spheres have unity dots physics on them, and they just fall down on a plane at startup. I do a classic build using the scriptable build pipeline, webgl target. When I run it in Chrome, I get the bellow error. Any ideas?

Seems like it’s still pretty broken. I tried it with the latest packages, running 2019.3.06f. I’m trying to run a fairly simple project and it immediately errors out at runtime:

Getting ecs to work in the browser without Tiny is a bit more involved. It’s not an officially supported target at the moment.
I made a sample with explanation and created a thread, check it out here:

Is there an existing ticket, or is it worth raising one? I’ve attempted a web-gl build of a working Windows build that uses ECS and while it does start the title (no ECS), as soon as it begins the game scene (with ECS), it crashes with index-out-of-bound errors in the player loop just iterating through systems.

(as an aside, I was getting crashes using il2cpp while Mono appears to work fine standalone)

edit: “WebGL and Burst compatibility should be hopefully fixed later this year, but we don’t have any precise ETA at the moment.” ( Burst for standalone players page-5#post-5364648)
