Learn about using line groups, which allow Yarn Spinner to choose which content to run, depending on conditions.
In Yarn Spinner 3, you can now create line groups. A line group is collection of lines that Yarn Spinner will choose from.
Line groups are collections of lines that begin with a => symbol:
When Yarn Spinner encounters a line group, it will select one of the lines in the group and run it.
Line groups are great for running ‘barks’ - collections of short lines that need to run in response to an in-game event. It can be useful to think of them like Yarn Spinner’s existing options -> syntax, but instead of the player choosing which content to run, the computer picks it for you:
You can attach conditions to lines in a line group, to ensure that they only run when it’s appropriate to do so. Conditions can be any true or false expression, and can also be combined with the once keyword to ensure that a line can only run once:
A line in a line group can also have additional lines belonging to it, which will run if the item is selected.
