Chapter 7 ■ The Foundation of Game Play Loop: The JavaFX Pulse System and the Game Processing Architecture Figure 7-15. Click Run ➤ Project, and open the Output pane to see errors being generated in .handle() Clearly, NetBeans 8.0 does not always write optimal code for the bootstrap methods that it codes for us, so let’s remove the throw new UnsupportedOperationException("Not implemented yet."); line of code (see Figure 7-13). In its place, you will insert a Java comment, which creates for now what is termed an empty method, shown in Figure 7-16. This should allow your game application to run. Although the game application window did launch with the thrown errors, the components of the Scene Graph were not written to the scene, and only a default white background color could be seen. You will observe this if you are following along in NetBeans. www.it-ebooks.info 157
Chapter 7 ■ The Foundation of Game Play Loop: The JavaFX Pulse System and the Game Processing Architecture Figure 7-16. Replace throw new UnsupportedOperationException(); with a comment, creating an empty method Now, let’s again use the Profile ➤ Profile Project (InvinciBagel) work process to see if anything new has appeared in the Live Results and Threads tabs in NetBeans. Click the Live Results icon, shown at the left of Figure 7-17, and start the Live Results Profiler in a tab. Note that the GamePlayLoop object is created, using , and that an AnimationTimer is started, using the invincibagel.GamePlayLoop.start() entry in the Profiler output. Figure 7-17. Use a Profile ➤ Profile Project menu sequence to start the Profiler, and look at GamePlayLoop memory use 158
