The
Level
class contains an
enum
data type that we will use to represent our entire
game world objects. These objects have a unique RGBA color value that is used to
identify them. We will not use the alpha channel and always expect full opacity for
our game object color values. As each color component is represented as an 8-bit
value, the sum of an RGBA color is 32 bits or 4 bytes. The
int
data type of Java is
also defined as a 32-bit value, which makes it the appropriate place to store RGBA
color codes in a compact way.
The compact color value is stored in RGBA format. Also, in the
following code, we are going to use bit shift operations. For more
