The ProjectileManager class completes the manager classes. Now, we will take a look at the final
custom class for our game—the Mine class.

Designing the Mine class
The Mine class is an extension of the BasicBlitArrayObject class with an update function
customized to implement the step modifier from the time-based step timer. The class is so simple
we will just show the code here and describe the update function when we get to the
BlasterMines update function.
This is the package location: com.efg.games.blastermines .
Here is the complete code for the class:
package com.efg.games.blastermines
{
import com.efg.framework.BasicBlitArrayObject;
