Creating an Optimized Post-Retro Game - The Essential Guide to Flash Games - page 534

public var particlesPerExplode : This is the number of Particle instances that will be
created for each explosion.
And these are the private attributes:
private var drawingCanvas:Shape : The canvas where the particle look will be
constructed
private var point0:Point : A reusable Point instance for drawing operations
This class's public functions follow:
public function ParticleManager() : The constructor is an empty function.
public function createParticlePool(maxParticles:int):void : The
BlasterMines.as class will call this function before each new level to create the particle
pool. We will see this in action and discuss it more when we go through the
BlasterMines.as code.
public function createLevelParticles(spriteGlowFilter:GlowFilter,
levelColor:uint):void : This function is called by BlasterMines.as before each new
level. It creates the look of the particles to match the color on the Mine instances.
