Creating a particle emitter

Now that we have an exhaust particle system, we are going to start adding the particle system code into the game to add some nice particle effects. I would like to have a particle system for the player and enemy ship exhaust. I would also like to add a particle system effect on top of the animated explosion we have to make it stand out.

The first thing we are going to do is copy the particle.cpp and emitter.cpp files into the main Chapter09 directory. After that, we will need to add those class definitions to the game.hpp file, as well as to the get_random_float function prototype.

Changes to game.hpp

The first set of changes we need to make are to the game.hpp file. We need to add an Emitter class...
