Example 8-19. ChangeHandler.as (continued) private function fireBeam (evt:Event) { beam.play ( ); aFlag=0; aeFlag=0; } //Android beam hits Alien or Earthling private function beamHit (evt:Event) { if (beam.hitTestObject(alienMC) && aFlag==0) { aFlag=1; aKiller++; scoreSetter.setScore (aKiller,"BeamHit on Alien"); dataOut ( ); if (aKiller >= 5) { scoreSetter.setScore (aKiller,"Alien Out"); alien.nomDeGuerre="Alien Destroyed"; this.alienMC.rotation=90; torpedo.rotation=90; killWarrior (alien); dataOut ( ); } } if (beam.hitTestObject(earthlingMC) && aeFlag==0) { aeFlag=1; eKiller++; scoreSetter.setScore (eKiller,"BeamHit on Earthling"); dataOut ( ); if (eKiller >= 5) { scoreSetter.setScore (eKiller,"Earthling Out"); earthling.nomDeGuerre="Earthling Off"; this.earthlingMC.rotation=90; missile.rotation=90; killWarrior (earthling); dataOut ( ); } } } //Alien Fires torpedo private function fireTorpedo (evt:Event) { torpedo.play ( ); lFlag=0; } //Alien hits Earthling private function alienHit (evt:Event) { this.earthlingMC=earthlingMC; Dynamically Changing States | 315
Example 8-19. ChangeHandler.as (continued) } } } if (torpedo.hitTestObject(earthlingMC) && lFlag==0) { lFlag=1; eKiller++; scoreSetter.setScore (eKiller,"Earthling Hit"); dataOut ( ); if (eKiller >= 5) { scoreSetter.setScore (eKiller,"Earthling Out"); earthling.nomDeGuerre="Earthling Off"; this.earthlingMC.rotation=90; missile.rotation=90; killWarrior (earthling); dataOut ( ); } } //Output Data private function dataOut ( ) { for (var i:int = 0; i < battleUpdate.length; i++) { battleUpdate[i].text=warrior[i].nomDeGuerre+ ":\n"+warrior[i].passOn( ); } } //Kill zone public function killWarrior (warship:ConcreteObserver) { scoreSetter.unsubscribeObserver (warship); } When you test the script, you’ll find that when you fire on the Android, only the Earthling’s hit can be seen as recorded. That’s because both the Alien and Earthling are hit by the same double-beam, and the Alien’s hit is recorded and broadcast first, quickly followed by the Earthling’s hit. As a result, you can see only the Earthling’s beam hit. Figure 8-6 shows the game after the Alien ship has been destroyed, and the Earthling’s still sustaining hits from the Android beam, but because the Alien stops receiving messages after it is destroyed, it doesn’t show the additional hits on the Earthling. While this example is not a true game, it does illustrate the great possibilities for sending score information to different subscribers in different formats. Likewise, it illustrates how the Observer design pattern effortlessly handles rapidly changing data through a single subject, and then quickly distributing it to different subscribers. 316 | Chapter 8: Observer Pattern
