Chapter 14 ■ Setting Up the Game Environment: Creating Fixed Sprite Classes Using the Actor Superclass Using the Prop Class: Creating Fixed Scene Objects Before we get into the coding in our InvinciBagel.java class, which you should have open in its own tab in NetBeans already, and use these Prop classes to add fixed sprite design elements to our game, I wanted to show you how to get rid of those pesky little wrench icons next to your file names. You may have several of these on your IDE screen right now, after creating these four new props-related classes, so let’s learn how to make these vanish! As you can see in Figure 14-17, if you right-click on the file name next to the wrench icon, and select the Compile File menu option, or use the F9 function key, the wrench will disappear. Essentially the wrench signifies that you are in the process of working on that file, that is, you have made changes to the code in that file, and have not made that code permanent, by compiling it to check it for errors as well as to save it. Figure 14-17. If you want to get rid of the little wrench icon next to the file name, right-click the file, and Compile File Adding Prop and Image Declarations: Prop and Image Objects Let’s start by declaring the objects that we will need to create to add fixed sprites to our game’s Scene and Stage objects, which will initially be a Prop object named iPR0, which stands for InvinciBagel Prop zero, and eventually as the chapter goes on, a PropH object named iPH0, a PropV object named iPV0, and a PropB object named iPB0, just so that you have experience using all of these classes and so that we can make sure that they all work in the way that we designed them to. We will also add an iP0 Image object declaration, and later on an iP1 Image object declaration, to the end of the Image iB0 through iB8 declarations. The <strong>Java</strong> statements are shown in Figure 14-18, and look like this: Prop iPR0; private Image iB0, iB1, iB2, iB3, iB4, iB5, iB6, iB7, iB8, iP0; 310 www.it-ebooks.info
Chapter 14 ■ Setting Up the Game Environment: Creating Fixed Sprite Classes Using the Actor Superclass Figure 14-18. Add Prop object declaration, name it iPR0 (invincibagel Prop zero), and add an iP0 to Image declaration Before we can instantiate the Image objects, we need to copy the Image assets into the /src folder, so use a file management software package (I used Windows Explorer) to copy the prop0.png and prop1.png PNG8 image files in with the other dozen or so image assets you have installed in the game project already, as is shown in Figure 14-19. Figure 14-19. Use your file management software to copy the prop0 and prop1 PNG8 files into the project /src folder 311
