Resolved Problems with interaction with GameObject from ECS

Version:
Unity: 2022.2.5f
Burst: 1.8.2
Entities: 1.0.0-pre.15

Hello

This might be a something small that i am missing at the moment, but i cant interact with the GameObject. In 0.17 i was able to make it work.

I can also se that the systemBase that i want to use for the gameobject dont print in the debug.
I dont get any errors or nothing so i am a bit confused, any hints or help would be nice.

I think i uploaded this question a bit hasty, i just missunderstod some of the new syntaxes with ECS 10. vs ECS 0.17.

Well here is my current temporary solution for sending data from ECS to GameObject. Will check out DOTS animation when i got some other stuff done, this will have to do.

A spawner object in a subscene.
