The
createPlayerExplode
function creates an explosion using
Particle
s from the
particlePool
(if enough are left in the pool).

The
createPlayerExplode
function creates an explosion where the player ship used to be. We
use the first frame of the
projectileAnimation
array of
BitmapData
instances. Instead of
creating a new particle, we use a
Projectile
BitmapData
because it is already the same color
as the player.
