Chapter 13 ■ Animating Your Action Figure States: Setting the Image States Based on KeyEvent Processing Figure 13-15. Use the Source ➤ Insert Code ➤ Generate ➤ Getter and Setter sequence and select aKey, dKey, sKey, wKey As you can see in Figure 13-16, NetBeans has created all eight of our getter and setter methods for the new KeyEvent processing variables that we have added to the InvinciBagel.java class. The code is error-free, and we are ready to go back into the Bagel.java class, and utilize some of these new method calls to implement jump and evade. 292 www.it-ebooks.info
Chapter 13 ■ Animating Your Action Figure States: Setting the Image States Based on KeyEvent Processing Figure 13-16. Hold a left arrow (or A) and up arrow (or W) key down at the same time, and move the Actor diagonally Adding Jump and Evade Animation: Using the W and S Keys Let’s start to put into place the infrastructure for using another set of four keys to give our players more flexibility in implementing sprite (character) actions (animation). Using the keyboard, these would use the ASDW keys, and using a game controller, these would use the <strong>Java</strong>FX KeyCode class constants GAME_A, GAME_B, GAME_C, and GAME_D. I’ll be adding game controller event handling a bit later on during my game development after I add in more game play logic. The implementation of the basic jump and evade (projectiles) sprite cel Image assets would be accomplished by using the following two basic <strong>Java</strong> conditional if() structures for using the W key via if(invinciBagel.iswKey()) and the S key via if(invinciBagel.issKey()) processing structures, which are shown below, as well as in Figure 13-17: if(invinciBagel.iswKey()) { spriteFrame.setImage(imageStates.get(5)); } if(invinciBagel.issKey()) { spriteFrame.setImage(imageStates.get(8)); } www.it-ebooks.info 293
