Chapter 17 ■ Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine Figure 17-2. Instantiate a scoreText object using a Java new keyword and call the .setText() and .setLayout() methods For now, we are going to use the X,Y position value of 365,565, as you can see in Figure 17-2. To be able to style this Text object, we will need to declare a private Font object, named scoreFont, as seen in Figure 17-3. Use the Alt-Enter work process again on the red error highlight, and select the “Add import for javafx.scene.text.Font” option. Figure 17-3. Add a private Font scoreFont declaration and use Alt-Enter and select “Add import javafx.scene.text.Font” www.it-ebooks.info 395
Chapter 17 ■ Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine Before we can use this scoreFont Font object to style the scoreText Text object, we will need to add this scoreText Text Node object to the JavaFX Scene Graph by using the root.getChildren().add(scoreText); Java statement, which is shown highlighted in Figure 17-4. If you forget to do this, you will see only white on your game screen after you click the PLAY GAME Button! Figure 17-4. Add the scoreText Text Node object to the JavaFX Scene Graph, using a .getChildren().add() method chain The next step, now that we can see the Text object in the Scene, is to instantiate the scoreFont Font object using the Java new keyword and a Font(String fontName, int fontSize) constructor method call. The Java statement to accomplish this is shown highlighted in Figure 17-5, and should look like the following: scoreFont = new Font("Verdana", 20); Figure 17-5. Instantiate scoreFont object with a Java new keyword and Font(String fontName, int fontSize) constructor 396 www.it-ebooks.info
