Java 2D Asteroids Part 6
Add the StationarySpaceObject.java class which really doesn't do anything. It is just a place holder.
StationarySpaceObject.java
public class StationarySpaceObject extends SpaceObjects
{
public StationarySpaceObject()
{
}
}
The SpaceMines.java object is a class that will be the space mines in the game. This class contains the Affine Transform object that will be used to transform the points to the location of the object in the world.
