Question Entities package errors when importing in existing project

When I try to import com.unity.entities in an existing project, unity gives me these errors:

Library\PackageCache\com.unity.entities@0.14.0-preview.19\Unity.Entities\Serialization\ManagedObjectBinarySerialization.cs(70,33): error CS0117: 'BinarySerialization' does not contain a definition for 'ToBinary'



Library\PackageCache\com.unity.entities@0.14.0-preview.19\Unity.Entities\Serialization\ManagedObjectBinarySerialization.cs(148,40): error CS0117: 'BinarySerialization' does not contain a definition for 'FromBinary'

Any idea how I could fix that?

 

Which Unity version? The last one supported on 2019.4 is 0.11, any newer version requires at least 2020.1

 

I'm using 2020.1.

 

There's an error in entities package 0.14.

If you open Packages\Entities\Unity.Entities\Serialization\ManagedObjectBinarySerialization.cs

go to line 70.

70            BinarySerialization.ToBinary(m_Stream, obj, parameters)

There is no definition for BinarySerialization.ToBinary().

Try opening the definition for it, your IDE won't find it.

 

Can you share you manifest? Maybe you installed the serialization package manually, if so, uninstall it and let the package manager solve the correct dependency for you.

 

My manifest

I only installed com.unity.entities and I let I let the package manager install the dependencies

 

Do you have any other errors on your console? Does that happen on a fresh project? Tried to reproduce here with no luck

 

Hmm, your manifest doesn't match with your package manager, there is no Hybrid Renderer on your manifest, but it is showing up on your package manager. Are you sure you are showing the right one? For comparison, this is my Package Manager when I copy & paste your manifest (Enable Preview Packages is on and Show Dependencies is on in the Project Settings):

 

Yes sorry, I copied my manifest first and then I also installed the hybrid renderer.

I have no other errors, but now I located the cause of error.

It's an asset I am using. I don't know why but anytime I have entities package installed, and this particular asset in my project folder, I get errors in the entities package. I will try to get insight from the developer of the asset.

 

Have you switched to. NET 4.0?

Are you upgrading from existing entities package to late 0.14?
As suggested earlier, check all packages dependencies, if they are matching.

 

Hey I'm having the exact same issue as you from an asset pack as well. Have you resolved this issue and if so, how? I'm using Entities version 0.16 and have my API Compatibility Level at .NET 4.x am I missing something else?

 

I haven't resolved the issue. All I did was contact the authors of the asset which was causing the issue and make them aware of the problem. I am still waiting for an update from them. In the meanwhile, I am using other assets which don't cause this problem with the Entities package.

 

Thank you, hopefully it gets resolved. Which asset was it for you that caused the problem? I wonder if it's the same asset as one of them in my project.

 

@aganm @XochiInteractive If you guys are using TerraWorld and have this problem, it's under investigation by our team. Please use this thread to follow-up on this and I'll try to update you when we have a solution: https://forum.unity.com/threads/33-...vel-designer-for-real-world-locations.784217/

 

@aganm @XochiInteractive @brunocoimbra We went through all the codes while TerraWorld and entities package are present in project and could not find collision parts as it happens occasionally and strangely!

But a temporary workaround is to replace the 2 following lines with errors in ManagedObjectSerialization.cs script:

Replace

Code (CSharp):

1. BinarySerialization.ToBinary(m_Stream, obj, parameters);

With

Code (CSharp):

1. Unity.Serialization.Binary.BinarySerialization.ToBinary(m_Stream, obj, parameters);

& Replace

Code (CSharp):

1. return BinarySerialization.FromBinary<object>(m_Stream, parameters);

With

Code (CSharp):

1. return Unity.Serialization.Binary.BinarySerialization.FromBinary<object>(m_Stream, parameters);

However they will keep reverting back to their initial states after project restart or deep compilation of packages.

 

A temporary workaround to this is explained here: https://forum.unity.com/threads/50-...al-world-locations.784217/page-6#post-7150999

 

UPDATE:
Good news, the conflicts between Unity Entities package and TerraWorld have been resolved by our dev team and now you can use DOTS along with TerraWorld in your projects.

Next version comes with the fix.

 

I tryed using TerraWorld today with Unity verson 2019.4.18f and have the same problem. and I'm looking forward to the new update

 

Sorry for the delay, next release has been delayed a bit but will be there soon with entities package and DOTS compatibility. Stay in touch with us here at Discord: https://discord.gg/9J6Jk7B
