 The Story System uses the Ink Language and runtime to navigate through a story written in a plain text file. This package contains the Story Module that receives an ink story and runs it. The story can show lines and branches, execute functions in unity and wait for events. Unity also has an API for navigating, getting and setting variables in the story.
