Tags and Metadata
A tag is a piece of information that you can add to content in Yarn Spinner that adds additional context or detail about that content.
There are two places you can add tags in Yarn scripts: you can add them to nodes, and you can add them to lines. Tags aren't shown to the user; instead, they're used by your game, or by Yarn Spinner itself.
Tags in lines
Tags can be added to the end of lines and options. Tags on lines start with a hash symbol (#), and cannot contain spaces. You can add as many tags as you like to line, but they must all be on the same line in the script.
Here's an example of a line with two tags:
Accessing tags
Tags that you add to a line can be accessed from your game. The way that you access them depends on your game engine. For example, to access them in a Unity game, you use the LocalizedLine.Metadata property.
Some tags are used by Yarn Spinner itself, while all others are used by your own code, so it's up to you what content they should have, and how to handle them.
Special tags
Certain tags are used internally by Yarn Spinner, or are added for you if they don't exist.
