Hi,

I’m very new to ECS and am trying to import the Boid scripts from the official Unity ECS Samples project into my own project.
The ECSSamples version I’m using is 2019.3.0f1, and the version of my project is 2019.2.10f1.

As I took the scripts from the samples project and imported them into my project, I got the error from the title.

I really don’t get what this attribute is for, and I therefore don’t understand why I get this error nor how to solve it. Would really appreciate some help on that one.

Thanks for reading

Entities 0.2 and above requires Unity 2019.3.

That attribute is used for the conversion workflow (see talk from Unite 2019) and requires the new Asset Database v2 that comes with 2019.3.

Okay thanks I get it better now. Was there a ECS samples project developped for 2019.2 ? I can’t seem to find one, but I’m not sure if I have searched properly.
