Extending Unity with Editor Scripting

By: Angelo R Tadres Bustamante

Overview of this book

One of Unity's most powerful features is the extensible editor it has. With editor scripting, it is possible to extend or create functionalities to make video game development easier. For a Unity developer, this is an important topic to know and understand because adapting Unity editor scripting to video games saves a great deal of time and resources. This book is designed to cover all the basic concepts of Unity editor scripting using a functional platformer video game that requires workflow improvement. You will commence with the basics of editor scripting, exploring its implementation with the help of an example project, a level editor, before moving on to the usage of visual cues for debugging with Gizmos in the scene view. Next, you will learn how to create custom inspectors and editor windows and implement custom GUI. Furthermore, you will discover how to change the look and feel of the editor using editor GUIStyles and editor GUISkins. You will then explore the usage of editor scripting in order to improve the development pipeline of a video game in Unity by designing ad hoc editor tools, customizing the way the editor imports assets, and getting control over the build creation process. Step by step, you will use and learn all the key concepts while creating and developing a pipeline for a simple platform video game. As a bonus, the final chapter will help you to understand how to share content in the Asset Store that shows the creation of custom tools as a possible new business. By the end of the book, you will easily be able to extend all the concepts to other projects.

Implementing the Level Creator modes


Until this point, we have specified the four modes the Level Creator tool would support and a way to switch between modes, thanks to the custom GUI we added in the top-left corner of the Scene View.

In this section, we discuss how to implement each of them.

The View mode

When you select View on Level Creator, you can move or zoom around the level grid.

In the method ModeHandler we defined, this mode will behave like the Unity View Transform tool. Let's take a look at following screenshot:

By default, you will see the hand icon on this mode; by clicking and dragging, you can move all the content in the Scene View.

The Paint mode

We started implementing part of the workflow related to this mode in the previous chapters. When this mode is selected, the user must select a piece from the Palette window, and a reference to this selection will be saved in the variable _pieceSelected in the LevelInspector class.

When the user starts clicking and dragging the mouse over...
