# 核心概念

“核心概念”部分解释了运行在你场景中每个 Convai 角色底层的系统——管理连接的运行时层、控制每个角色生命周期的会话状态机、驱动 Gaze 和 Emotion 等模块的按角色实体化层、控制谁发言以及何时发言的轮流发言系统，以及让场景在运行时对发生的事件做出反应的事件组件。

从……开始 **运行时架构** 如果你对 SDK 内部机制还不熟悉。只有在需要配置某个特定系统，或想了解 SDK 为什么会以某种方式运行时，再阅读其他页面。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.convai.com/api-docs/zh/cha-jian-yu-ji-cheng/convai-unity-sdk/core-concepts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
