Unity DOTS

This post is going to be a summary of the official Entities package document, kind of a cheat-sheet.

The following operations are considered structural changes:

• Creating or destroying an entity
• Adding or removing components
• Setting a shared component value

Physics

• All physics objects that are in the scene but outside the subscene will be ignored since they don't get converted to entities.

• A World organises entities into isolated groups. A World owns both an EntityManager and a set of Sytems. In a multiplayer game, it makes sense that client and server are different Worlds.
