You are missing the Image2D native web reference on you assembly definition. On the phone now so I don’t know the precise name.

 

Actually your project should compile fine but if you still have problems try including Unity.Tiny.Image2D.Native into you root assembly definition.
I also seen that you are trying to write on a readonly dynamic buffer and are not disposing of them afterwards.
Change line 116 of SetCrewsJobSystem.cs to:

Code (CSharp):

1. var blockDefinitionBuffers = GetBufferFromEntity<BlockDefinitionBuffer>(false)[blockMatrixEntity];

And add to the end of your Update function:

Code (CSharp):

1.       setCrewsJob.BlockCrewBuffers.Dispose();
2.       setCrewsJob.BlockDefinitionBuffers.Dispose();

 

I have this issue as well. I added Unity.Tiny.Image2D.Native and this did not solve the problem.

Using the DOTs Tiny2D starter package.

The repo itself seems to have this issue and will not run out of the box

I'm on unity version 2020.3.13f1
It installs Project Tiny Full Version 0.32.0-preview.55

 

You should use Unity 2020.1.17f1.

I did not have the DLL problem but I can only test on Mac for now. Built .NET and IL2CPP without such problems.

 

Thank youu sir

 

Having the same issue with TinySpaceship sample on Unity 2020.3.3. Unity.Tiny.Image2D.Native is included in Assets/Scripts/Runtime/TinySpaceship.asmdef

Why do you use Unity 2020.3.3 when the "Get Started" specifically state to use Unity 2020.1.17f1?

 

Get started said it's minimum required version.
Btw, I have the same problem with Tiny2D sample on 2020.1.17

Update:
I guess running the scene through standard play button is wrong, trying to build project through asset in build folder but having problem with compiler. Maybe just Rider is not enough and you need to have Visual Studio compiler installed.

Update 2:
Success! I was able to run Tiny2D sample through asset in build folder, Visual Studio 2019 with all prerequisites listed in Google Doc is still required, even if you have Rider installed.

 

You can’t play the game in the editor because some packages simply won’t run (eg. Renderer). But you still can test your systems as in regular DOTS.
As mentioned in the docs you must build using the builds scripts for a scriptable build pipeline and you can attach your IDE to the running build (if DEBUG build) and set breakpoints and so on…
I also advice on creating Unit Tests for your systems as it will save you a lot
of time in the end.

 

I have the exact same 2 errors, build works but play doesn't, did you solve this?

 

As I said before and from reading the "Getting Started Guide", you can't play the tiny projects in the editor.
Well, that is not entirely true but several key systems won't work (eg. rendering), but you can still do a fair amount of testing with your systems as long as they do not depend on editor missing features.

 

Yes I sadly read this...
The last version of the project was in jan 25, is the project dead?

 

We were promised for status update here: https://forum.unity.com/threads/is-the-project-dead.1109039/#post-7349246

 

Not quite. We were told someone would poke someone. Far from the promise of a status update.

We were also told in the DOTS compatibility thread months ago that they would "catch up with questions." However, we are still waiting for any additional response.

 

Right-o. I guess Tiny is so much DOTS, that if they are busy fixing and implementing things in Core and DOTS libs in general, is understandable that new Tiny based on those is delayed. Also it was kind of experimental to begin with, interesting to see where they take the lessons. We are now testing normal WebGL builds on mobiles for our things again, tested with Tiny too earlier. Is ok for our current things to be a bit heavier to start, and 2021.2 beta already brings some improvements.
