tected. This also allows us to completely eliminate the if(collisionDetect) structure as
well.
Before this optimization, we had 6 lines of code in the .checkCollision() method,
and 19 lines of code in the .collide() method. After the optimization, we have 5 less
lines of Java code, with 10 lines of code in each method. The new Java structures for
these methods are error-free, as shown in Figure 16-41 , and look like the following
Java code:
public void checkCollision () {
for(int i=0;
i<invinciBagel.castDirector.getCurrentCast().size(); i++)
{
Actor object =
invinciBagel.castDirector.getCurrentCast().get(i);
If ( collide ( object )) {
invinciBagel.playiSound0();
invinciBagel.castDirector.addToRemovedActors( object );
invinciBagel.root.getChildren().remove( object .getSpriteFrame());
invinciBagel.castDirector.resetRemovedActors();
}
}
}
@Override
public boolean collide (Actor object ) {
if
(invinciBagel.iBagel.spriteFrame.getBoundsInParent().intersects(
object .getSpriteFrame().getBoundsInParent() ) ) {
Shape intersection =
SVGPath.intersect(invinciBagel.iBagel.getSpriteBound(),
object .getSpriteBound());
if
(intersection.getBoundsInLocal().getWidth() != -1 ) {
return true;
}
}
return false;
