Dynamic Story Scripting with the ink Scripting Language

By: Daniel Cox

Overview of this book

ink is a narrative scripting language designed for use with game engines such as Unity through a plugin that provides an application programming interface (API) to help you to move between the branches of a story and access the values within it. Hands-On Dynamic Story Scripting with the ink Scripting Language begins by showing you how ink understands stories and how to write some simple branching projects. You'll then move on to advanced usage with looping structures, discovering how to use variables to set up dynamic events in a story and defining simple rules to create complex narratives for use with larger Unity projects. As you advance, you'll learn how the Unity plugin allows access to a running story through its API and explore the ways in which this can be used to move data in and out of an ink story to adapt to different interactions and forms of user input. You'll also work with three specific use cases of ink with Unity by writing a dialogue system and creating quest structures and other branching narrative patterns. Finally, this will help you to find out how ink can be used to generate procedural storytelling patterns for Unity projects using different forms of data input. By the end of this book, you will be able to move from a simple story to an intricate Unity project using ink to power complex narrative structures.

Observing multiple ink values

Along with the ObserveVariable() method is a sister method named ObserveVariables(). However, while the ObserveVariable() method accepts the name of a variable and a delegate function, the ObserveVariables() method accepts an IList<string> of variable names and a delegate function. Instead of responding when a single variable is changed, its delegate function is called when any of the variables passed as a list to the method are changed. While slightly more complicated to set up, the ObserveVariables() method provides the functionality to observe multiple ink variables.

Recommendation

It is recommended that you create a new Unity 2D project for this section. Instructions regarding how to create a new Unity project and import the ink-Unity Integration plugin can be found in Chapter 6, Adding and Working with the ink-Unity Integration Plugin.
