# Feature Tour

![The Feature Tour Sample.](https://463139507-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FGAKWviXNATe9kDFWZAco%2Fuploads%2Fgit-blob-becf90f689bd638df37e1943c19e57128e947084%2Fgauntlet-01.png?alt=media)

The Feature Tour Sample is an ideal starting point for newcomers to Yarn Spinner. It presents a series of conversations along a corridor, each demonstrating a different capability of Yarn Spinner.

Are you ready to navigate this narrative gauntlet?

## Tour Structure

The feature tour consists of a long corridor with multiple rooms. Each room contains one or more interactive characters, with each character showcasing a specific Yarn Spinner feature. While this sample doesn't demonstrate every Yarn Spinner capability, it covers the most commonly used ones.

### Dialogue Interactible Component

At the heart of this feature tour is a class, **Dialogue Interactible**. This component is attached to each interactive character and associates a specific dialogue node with that character. If you're curious about how a particular feature works, you can identify which node contains that feature through this component.

For example, if you want to see which node provides dialogue for a specific character, select that character in the scene and examine the Dialogue Interactible component.

In this example, we can see the node is `Room4_Variables_2`. Since all dialogue in this sample is contained in a single file (`Tour.yarn`), you simply need to open that file and locate the node to understand its implementation.
