public var projectilePool : This one contains an array of the projectiles in the pool.
public var projectile Count : This class-level variable will hold the length of the
projectiles array.
public var projectile PoolCount : This class-level variable will hold the length of the
projectilePool array.
public var tempProjectile:BasicBiltArrayProjectile : This reusable class-level
Projectile instance for loops through array the Projectile arrays.
public var projectilePoolMax : This attribute holds the total number of projectiles
that can be on the screen at a single time.
The private attributes are
private var drawingCanvas:Shape : The canvas where the projectile look will be
constructed
private var point0:Point : A reusable point instance for drawing operations
And these are the public functions:
public function Projectile Manager() : The constructor is an empty function.
public function createProjectilePool(maxParticles:int):void : The
BlasterMines.as class will call this function before in its init function to create the
projectile pool. We will see this in action and discuss it more when we go through the
BlasterMines.as code.
public function createProjectilePool(maxProjectiles:int):void : This function is
called by BlasterMines.as before init . It creates the look of the projectiles.
