I had the same question. "The Entity Component System (ECS) is the core of the Unity Data-Oriented Tech Stack. As the name indicates, ECS has three principal parts: Entities — the entities, or things, that populate your game or program. Components — the data associated with your entities, but organized by the data itself rather than by entity. (This difference in organization is one of the key differences between an object-oriented and a data-oriented design.) Systems — the logic that transforms the component data from its current state to its next state— for example, a system might update the positions of all moving entities by their velocity times the time interval since the previous frame" From https://docs.unity3d.com/Packages/com.unity.entities@0.17/manual/index.html https://docs.unity3d.com/Packages/com.unity.entities@0.17/ma...
