Figure 17-38. Add an if(onScreen) level of processing inside the if(takeSides) logic to animate a sprite from the left side
Weaponizing the Enemy: Shooting Projectile Objects
Now that we have the Enemy animating onto (and off of) both sides of the screen, the next level of complexity that
we need to add is the shooting of Projectile objects. We’ll first implement iBullet objects (negative score generation)
and later iCheese objects (positive score generation), both of which will require our Enemy.java class to have visibility
into the InvinciBagel class. Thus, the first thing that we’ll need to do is to modify the Enemy() constructor method to
accept an InvinciBagel object using the Java this keyword, much like we did with our Bagel() constructor method. Go
into the InvinciBagel.java class and add a this keyword to the front end of (beginning of) your Enemy() constructor
parameter list, as shown highlighted in Figure 17-39, using the following amended Enemy() constructor method call:
iBeagle = new Enemy(this, "M0 6 L0 52 70 52 70 70 70 93 115 45 115 0 84 0 68 16 Z",520,160,iE0);
