In-Depth Information
If local storage has not yet been set for the game, it is created by using the
dataTemplate
object within the
setLocalStorage
method and is then set to the
player
property. Figure
14-5
shows some saved data in local storage
by using a Local Storage Manager extension for Chrome.

The player stats stored in local storage
With the data set for the game, player stats, and the enemies, it's time to build the
Enemy
and
Hero
classes.
Building the Enemies and Hero
All enemies will use the same
Enemy
class. It should simply take a data object, retrieved by the
EnemyData
object, and
appear and function accordingly. The
Hero
class will simply represent the current stats in
PlayerData
and will be used
to play the level. Both classes will be built in this section.
Creating the Enemy Class
The
Enemy
class will be a container that holds two consistant display objects. One is a sprite for the enemy sprite sheet
frame, and the other is for its health meter, which will be its own container class as well. The
Enemy
class has a few
other elements and a number of things going on so I'll break it down into a few parts, starting with the properties and
initialize method (see Listing 14-9).
