Unity-ECS从入门到关门

ECS(Entity Component System)是Unity Data Oriented Tech Stack的一部分，是其默认的高性能编码方式。

也就是我经常看到的那个DOTS的一部分啦，其他部分的话暂时先不管（有点管不过来），这东西完全是一个新的概念，或者说试图用以前的Unity的GameObject，MonoBehavior的概念去理解的话，就会掉坑里，完全不知所云。拿面向对象的思想去套貌似也会吃点亏，当然我还没到这个地步只是听说的。

Entity Component System

• Entity Component System

  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.

如何理解这个概念？看上面的英文。如果想要细致的理解，我觉得上面那个链接的内容都要看。

关于ECS的博文有一些很重要，或者说我是读了这些博文才逐渐能理解ECS的。

• World, system groups, update order, and the player loop

这里讲到了我在UniRx文章中提到的PlayerLoop的内容，有时间整理一下。

• On DOTS: Entity Component System

Unity Blog中的一篇文章，我觉得Unity的官方博客里面有好多非常好的文章，时常关注一下没有坏处（我得看啊）。
