近年来，实体-组件-系统模式已成为Unity和Unreal等游戏开发环境的软件架构的基本特征，这些环境广泛用于开发3D用户界面。在这些系统中，UI组件通常响应事件，要求程序员编写特定于应用程序的回调函数。在某些情况下，组件被组织在用于在垂直连接的组件之间传播事件的层次结构中。当组件需要水平通信时，程序员必须手动连接这些组件，并根据需要注册/取消注册事件。此外，事件和回调签名可能不兼容，这使得模块化UI在应用程序内或跨应用程序构建和共享起来很麻烦。为了解决这些问题，我们引入了一个消息传递框架Mercury，以促进组件之间的通信。我们提供了一个水星的概述，概述其底层协议，以及它如何使用中继节点将消息传播给响应者，描述了在Unity中的参考实现，并介绍了使用水星构建的示例系统，以解释其优势。
In recent years, the entity--component--system pattern has become a fundamental feature of the software architectures of game-development environments such as Unity and Unreal, which are used extensively in developing 3D user interfaces. In these systems, UI components typically respond to events, requiring programmers to write application-specific callback functions. In some cases, components are organized in a hierarchy that is used to propagate events among vertically connected components. When components need to communicate horizontally, programmers must connect those components manually and register/unregister events as needed. Moreover, events and callback signatures may be incompatible, making modular UIs cumbersome to build and share within or across applications. To address these problems, we introduce a messaging framework, Mercury, to facilitate communication among components. We provide an overview of Mercury, outline its underlying protocol and how it propagates messages to responders using relay nodes, describe a reference implementation in Unity, and present example systems built using Mercury to explain its advantages.
