# Emotion

Find guides for a Convai character's facial expression and mood, from first setup through the scripting API and troubleshooting.

Emotion drives a Convai character's facial expression and its longer-lived resting mood. Part of its input arrives with Convai's response; the rest is yours to configure and script. This section covers everything from a first working setup to mood control, taxonomy authoring, and the complete scripting API.

### Next steps

Start with [Emotion quick start](/api-docs/plugins-and-integrations/convai-unity-sdk/embodiment/emotion/quick-start.md) to get expressions running on your first character. Then read [How the emotion system works](/api-docs/plugins-and-integrations/convai-unity-sdk/embodiment/emotion/how-the-emotion-system-works.md) to understand the pipeline and where its input comes from before moving into mood control and reference pages.

## 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/plugins-and-integrations/convai-unity-sdk/embodiment/emotion.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.
