Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine - Beginning Java 8 Games Development - page 563

a break; statement in a switch-case structure. To optimize this even further, you
would want to place the most common (the highest number of collidable objects in the
Scene of that object type) objects at the top of this if-else-if structure, and the least
common objects at the bottom of the structure. All you have to do to accomplish this is
tie your if() condition blocks together by using the Java else keyword, as shown in Fig-
ure 17-12 . This creates a more compact and processing-optimized conditional evalu-
ation structure, and uses fewer lines of Java code:

private void scoringEngine(Actor object ) {
if( object instanceof Prop) {

invinciBagel.gameScore+=5;
invinciBagel.playiSound0();
} else if (object instanceof PropV) {
invinciBagel.gameScore+=4;
invinciBagel.playiSound1();
} else if (object instanceof PropH) {
invinciBagel.gameScore+=3;
invinciBagel.playiSound2();
} else if (object instanceof PropB) {
invinciBagel.gameScore+=2;
invinciBagel.playiSound3(); }
invinciBagel.scoreText. setText (String.valueOf(invinciBagel. gameScore ));

}
