How to create your first Entities and System with Unity DOTS

[@WAYNGames]

Hello, Unity relased the ECS 1.0 experimental version. The core concepts discussed in this video are still relevant but some changes need to be taken into account. You can still use systembase and Entities.Foreach even if they are no longer the recommended solution for 1.0. The translation and rotation componeents have beed replaced by a single TransformAspect "component". The RenderMesh component is no longer set on hte cube you can set the RenderBounds insted. Happy learning !

I don't see any "ConvertToEntity" checkbox using 1.0.0-pre15. Do we need to use a Baker instead?

[@WAYNGames]

Yes you need to use subscenes and baker. Check out episode 5 of the series.

@@WAYNGames Hi. I tried using Unity 6 but it seems a lot has changed. I like your presentation style though and maybe you would consider updating the videos to follow along.

[@WAYNGames]

@@AtmosMr looks like you found the updates series. kzbin.info/aero/PL6ubahbodJ3OMKeICEIfVE268GGzGLkoU&si=SKMtD8LSQq6nHSl0 This one should be closer to the latest versions. If you have any trouble come ask on stream every Monday Wednesday and Friday, or on discord any time;)

using Entites 1.0.0-pre.65 remove mouse right click menu -> ECS -> System Script but, create basic C# script. and it inherits SystemBase. Also, it appears that "Translation struct" and "Rotation struct" have been removed in the latest version. I looked at the official documentation and handled it with LocalTransform. It seems that Time.DeltaTime has also been changed to World.Time.DeltaTime. Additionally, since the "Entities.WithAll" classification seemed to be subdivided, I changed the code to WithAll() and tested it.

[@WAYNGames]

Thanks for sharing your feedback on what changed in the API since the video. A more up to date series will start this week so stay tuned ;)

I get the following error, "error DC0223: Entities.ForEach uses ISharedComponentData type RenderMesh. This is only supported when using .WithoutBurst() and .Run()." . I switch the Schedule() to Run() and I get the same error.

[@lemuelapperson853]

"Entities.WithAll().ForEach((ref Translation translation, in Rotation rotation) => { " Worked for me. I dropped the 'in RenderMesh mesh' .
