Chapter 2 ■ Setting Up Your Java 8 IDE: An Introduction to NetBeans 8.0 NetBeans 8.0 Is Efficient: Organized Project Management Tools A good programming IDE needs to be able to manage projects that can grow to become quite massive, involving more than a million lines of code contained in hundreds of folders in the project folder hierarchy and thousands of files and new media assets. For this reason, project management features must be extremely robust in any mainstream IDE. NetBeans 8.0 contains a plethora of project management features that allow you to look at your Java 8 game development project, and its corresponding files and their interrelationships, in a number of different ways. There are four primary project management views, or “panes” that you can use to see the different types of interrelationships in your project. (I call them panes, as the entire IDE is in what I call a window). I jumped ahead (to the end of the chapter, once your Java 8 game project has been created) and created the screenshot presented in Figure 2-1. This screenshot displays the four project management panes opened in this new project so that you can see exactly what they will show you. Figure 2-1. Project management panes, at the left of the IDE, include Projects, Files, Services, and Navigator The Projects pane, at the left of the screen, shows the Java Source Packages and Libraries that make up your (game) project. The next pane over is the Files pane, which has the project folder and file hierarchy on your hard disk drive. The Services pane contains the databases, servers, repositories, and build hosts, if they are used in the project (these are primarily server-side technologies, and technologies used with a development team, so I am not going to go into these in detail). The Projects pane should always be left open (as you will see in Figures 2-7 through 2-21). The Projects pane provides you with a primary access point for all the project source code and assets (content) in your Java 8 game project. The Files pane shows not only the project folder and file hierarchy, but also the data and FXML markup (JavaFX) or Java 8 code hierarchy inside each file. The Navigator pane (bottom) shows the relationships that exist inside your Java code structures. In this case, these are the InvinciBagel class, the .start() method, and the .main() method (for further information, see Chapter 3). www.it-ebooks.info 21
Chapter 2 ■ Setting Up Your Java 8 IDE: An Introduction to NetBeans 8.0 NetBeans 8.0 Is User Interface Design Friendly: UI Design Tools NetBeans 8.0 also has Design a GUI drag-and-drop design tools for a plethora of platforms, including Java SE, Java EE, Java ME, JavaFX, and Java Swing as well as C, C++, PHP, HTML5, and CSS3. NetBeans provides visual editors that write the application’s UI code for you, so all you have to do is make the visual on the screen look like what you want it to look like in your game application. Because games use the JavaFX new media (game) engine, you will be learning about the JavaFX Scene Builder, an advanced FXML-based visual design editor, in Chapter 5 of this book. JavaFX has the Prism game engine as well as 3D (using OpenGL ES [OpenGL for Embedded Systems]) support, so I will be focusing quite a bit on the JavaFX Scene Graph and JavaFX APIs. The assumption here is that you will want to build the most advanced Java 8 games possible, and leveraging the JavaFX engine, which is now a part of Java 8 (along with Lambda Expressions), is going to be the way to accomplish this. The fastest way to develop a game is to leverage advanced code and programming constructs that the Java 8 and JavaFX environments generously give you for your use in creating cutting-edge applications (in this case, games) that contain powerful new media elements. NetBeans 8.0 Is not Bug Friendly: Squash Bugs with a Debugger There is an assumption across all computer programming languages that the negative impact to your programming project of a “bug,” or code that does not do exactly what you want it to, increases in magnitude the longer it remains unfixed, so bugs must be squashed as soon as they are “born.” NetBeans bug-finding code analysis tools, and integrated NetBeans Debugger, and integration with the third-party FindBugs project, which, as you now know from experience (Audacity), can be found on the SourceForge web site (http://findbugs.sourceforge.net) (if you want the stand-alone version), all supplement the real-time, “as you type” code-correcting and efficiency tools I discussed earlier (see the section “NetBeans 8.0 Is Smart: Put Your Code Editing into Hyperdrive”). Your Java code will not be very complicated until a bit later in the book, so I will cover how these tools work when you need to use them, once your knowledge base is a bit more advanced. NetBeans 8.0 Is a Speed Freak: Optimize the Code with a Profiler NetBeans also has something called a Profiler, which looks at your Java 8 code while it is running and then tells you how efficiently it uses memory and CPU cycles. This allows you to refine your code and make it more efficient in its use of key system resources, which is quite important for Java 8 game development, as this will affect the smoothness of game play on systems that are not as powerful (e.g., on single- and dual-core CPUs). This Profiler is a dynamic software analysis tool, as it looks at your Java code while it is running, whereas the FindBugs code analysis tool is a static software analysis tool, as it simply looks at your code in the editor, when it is not compiled and running in system memory. The NetBeans Debugger will allow you to step through your code while it is running, so that tool can be viewed as a hybrid that ranges from a static (editing) to a dynamic (executing) code analysis mode. After you create the foundation for your Java 8 (JavaFX) game engine (in the following sections), you will run the Profiler to see how it works inside NetBeans IDE 8.0. I am going to present as many key features of NetBeans as possible up front so that you get comfortable with this software. 22 www.it-ebooks.info
