Chapter 10 ■ Directing the Cast of Actors: Creating a Casting Director Engine and Creating the Bagel Actor Class
The easiest of these three methods to write is the .getRemovedActors() method, which simply uses a return
keyword to pass the entire HashSet Set object to a calling entity. This provides access to REMOVED_ACTORS
to other methods, such as the ones we will be writing later on in this section. The Java code should look just like this:
public Set getRemovedActors() {
return REMOVED_ACTORS;
}
The next method we’ll need to code is the most complicated as well as the most often used, as it will be the one
you use when something in your cast has changed: for instance, a killed enemy, such as an InvinciBagel, a spent
projectile, such as a bullet, consumed food, such as a ball of cream cheese, or found treasure, such as a gift box.
The .addToRemovedActors() method uses the if-else statement, to ascertain if multiple Actor objects have been
passed in the parameter list (the first or if part of the construct) or if just one Actor object needs to be removed (the
second or else part of the construct). The first part of the if-else statement uses the .length() method to ascertain if
more than one Actor objects has been passed into the method call parameter list using if(actors.length > 1) since
an Actor... parameter allows more than one Actor object to be submitted to the method, as seen in Figure 10-9.
