Overview

Package ec 提供了一个EC（Entity-Component）组件框架，用于帮助开发者组织代码架构。

在这个框架中，我们有以下核心概念：

  • Entity（实体）：代表了应用程序中的一个实际对象。以游戏举例，可以是场景，也可以是玩家、NPC、物品等。实体本身只提供生命周期管理、组件管理两项核心能力，行为和属性将由不同的组件来提供。
  • Component（组件）：为实体提供行为与属性，不同的组件可以为实体提供不同的行为和状态。以游戏举例，为实体添加兔子外观组件、飞行组件、挖洞组件，那么我们将会得到一个即会飞行又会挖洞的拥有兔子外观的实体。
  • Context（上下文）：实体的运行环境，通常用于提供全局属性与方法。因为Golaxy主要用于服务器逻辑开发，需要支持多线程并发环境，所以提供了运行时上下文（runtime context）、服务上下文（service context）两个上下文，分别对应本地单线程环境与并发多线程环境。

EC组件框架基于组合模式，在大部分情况下优于继承模式，开发者可以更好地组织代码，实现高内聚和低耦合的代码架构。
