Hey ! I'm trying to get started with the new ECS system, but after following the installation steps, I'm stuck with an error saying: /home/mehdi/.config/unity3d/cache/packages/packages.unity.com/com.unity.entities@0.0.12-preview.5/Unity.Entities/SerializeUtility.cs(153,52): error CS1644: Feature `out variable declaration' cannot be used because it is not part of the C# 6.0 language specification I have no idea what it means. Any help ? Thanks a lot !
Not sure what tutorial you followed, but Brackeys just released a tutorial video of a basic setup for it . Maybe just verify you didn't miss a step.
This error seemingly represented in preview.5 version of ECS. Probably latest update is assumed to be used with 2018.2 beta
did you see https://forum.unity.com/threads/fea...ed-error-on-entities-0-0-12-preview-5.534240/? only insert a file called mcs.rsp into the Assets folder with the content -langversion:experimental in it. Credits to mEndlessLoop who posted this. Have no idea what this does, but lets you use the new preview.
