Bug Entities 1.0 2D URP fix

This is a workaround fix to following post here (locked) and for anyone having this bug with 2d.Animation package which I also just encountered in latest version 2022.2.1f1 and Entities 1.0.0-pre.15.
I've only briefly tested this but the changes seem pretty inconsequential so can't see it causing issues.

com.unity.2d.animation@9.0.1/Runtime/TransformAccessJob.cs

Code (CSharp):

1. // Line 165
2. log += "TransformData Count: " + m_TransformData.Count + "\n";
3. //log += "TransformData Count: " + m_TransformData.Count() + "\n";

com.unity.2d.animation@9.0.1/Editor/MeshUtilities.cs

Code (CSharp):

1. Line 32
2. var outlineEdges = new NativeList<int2>(edges.Count, Allocator.Temp);
3. //var outlineEdges = new NativeList<int2>(edges.Count(), Allocator.Temp);
4.  
5. Line 41
6. return outlineEdges.AsArray().ToArray();
7. //return outlineEdges.ToArray();

Edit: Added original error for searchability.
Library\PackageCache\com.unity.2d.animation@9.0.0-pre.3\Runtime\TransformAccessJob.cs(165,62): error CS1955: Non-invocable member 'NativeHashMap<int, TransformAccessJob.TransformData>.Count' cannot be used like a method.

 

When I change it, Unity reverts it.

The package cache was invalidated and rebuilt because the following immutable asset(s) were unexpectedly altered:
Packages/com.unity.2d.animation/Runtime/TransformAccessJob.cs
Packages/com.unity.2d.animation/Editor/MeshUtilities.cs

 

Yes you can't just edit the PackageCache files. They're copied in there from an original source somewhere. On Linux they're here ~/.config/unity3d/cache/packages but I don't know where they are on Windows sorry. I've always just changed the original source files, not the PackageCache ones.

However in searching, I found this, so I think you can straight copy the com.unity.2d.animation@9.0.1 folder from YourProject/Library/PackageCache to YourProject/Packages and that seems to override/replace Unity's version.
I'd never done that before but it appears to work in my quick testing.

 

I did fix it in the same way, but added

Code (CSharp):

1. using System.Linq;

on the top of these files instead. It seems working so far.

 

It's a bit late, but in 2022.2.12, you can go to preferences / Package Manager to see where your packages are being stored. That's how I found them.

 

Can confirm that updating 2D Animation package to 9.0.2 fixed the issue for me. 2022.2.12
