I cannot figure out what this error message means

Library/PackageCache/com.unity.2d.animation@3.2.2/Runtime/TransformAccessJob.cs(196,62): error CS1061: 'NativeHashMap<int, TransformAccessJob.TransformData>' does not contain a definition for 'Length' and no accessible extension method 'Length' accepting a first argument of type 'NativeHashMap<int, TransformAccessJob.TransformData>' could be found (are you missing a using directive or an assembly reference?)

 

The chance is that you are either missing a package which is needed by this animation package (see the dependencies in the package manager), or you have different versions or you have the wrong Unity version. Check the package dependencies, make sure you have all of the dependencies and the right versions and if you do, head over the 2D forum, where the 2D experts are.

I have the same exact error. Still haven't figured it out.

 

hi there I have the same issue, I just installed the "2D Animation" package using the Package Manager and it doesn't highlight any dependency issue.
edit: I'm using unity 2019.4 LTS

 

sorry for the double post but I found a "fix". As this stackoverflow user points out, downgrading the Jobs package from 0.2.10 to 0.2.9 solves the issue.
Warning: if you're using Entities and Hybrid Renderer you'll need to downgrade also those packages as their last version requires the latest Jobs package.

I think this is to be expected as these are preview packages and they're probably already flooded with bug reports ;P

 

Thank you!!!!!!!!!!!!!

 

NativeHashMap<TKey, TValue> in Unity.Collections does not have a Lenth property. Use the Count() method instead.

You can edit the TransformAccessJob.cs file in your {project} \Library\PackageCache\com.unity.2d.animation@3.2.3\Runtime\TransformAccessJob.cs file Line 196. Change Lenght to Count().

 

Regardless of what version of Unity and the 2D animation package I use, I get this error. Manually changing it to Count() is a really bad solution since any change refreshes the Package Cache and overwrites the changes we make to it. This should really be fixed by Unity!!!

 

Came across this as well, using Unity 2019.4, 2D animation package version 3.2.3
Unfortunately downgrading the Jobs to 0.2.9 doesn't seem to solve the issue anymore.

 

Hi,
I have the same error.
I'm using 2019.4.0f1 LTS Pro.

I downgraded Jobs to 0.2.9, and all dependencies, but it did not work out for me.

I ended up downloading Unity 2019.3.12f1 and it works fine.

 

Same here... I was quite excited to use bone animation with the jobs system, but looks like it will have to wait.

 

I change m_TransformData.Length to m_TransformData.Count() and it works.

TransformAccessJob.cs 196

 

According to the Collections package v0.9 changelog:

Downgrading to v0.8 solves the issue. We'll have to wait for the package to be updated to support `Count()`.

 

kind of boring to change every package update the 2D animation transformaceessjob.cs line m_TransformData.Length to m_TransformData.Count().


Hope there will be a fix soon for that, this issue is very annoying for our team.

 

Update to the newest version for the 2D Animation Package- that worked for me!

 

Thank you. It was working also for me.

 

I have this error myself, trying project tiny for the 1st time. Unity version 2019.4.10f1 I updated to the newest animation version 3.2.5 and the error went away! Thanks lewisjet

 

Basically the same issue with Entities 1.0.0-pre.15 and 2D animations. With the updated collections package that "Count()" property has now turned into just "Count" in the TransformAccessJob.cs. Can we get another update to the 2D animations package to fix this one?

Versions:
Collections 2.1.0-pre.2
2D Animation 9.0.1

Entites 1.0 depends on Collections 2.1.0-pre.2.

Edit: Also happening with 2D PSD Importer 8.0.2
