# Guard Fields

Storyspace offers several convenient functions for use in guard fields.

guard(guard field) is `true` if the legacy guard field inside the parentheses is true.

visited(/path/to/note) is `true` if that note has been visited in this reading. visited() with no arguments is true is equivalent to visited(destination), and is true if the destination has previously been visited.

unvisited(/path/to/note) is `true` if that note has not been visited in this reading. unvisited() with no arguments is true is equivalent to unvisited(destination), and is true if the destination has not been visited in this reading.
