Designing the ProjectileManager class
The structure of the ProjectileManager class is almost identical to that of the ParticalManager
class. The major difference is that the projectilePool is only created a single time per game
session unlike the particle pool, which is recreated every level. The projectiles will be instances
of the BasicBlitArrayProjectile class.
The location for this package is com.efg.games.blastermines .
The public attributes for this class are

public var projectileBitmapData:BitmapData : This is the BitmapData look for the
Projectiles .

public var projectileAnimationFrames : Projectile s rotate as they fly through the air.
The rotation animation frames will be stored in this array. It will be created with the
BlitArrayAsset class.

public var projectiles:Array : This attribute contains an array of the current active
Projectile s.
