Summary

This Chapter has us well on our way to implementing a playable version of Asteroid Belt Assault. We have covered the following:

• Building a generic Sprite class to represent objects within the game world

• Creating a scrolling StarField using a large number of sprites that update their own positions and a class to encapsulate the management of the StarField as a whole

• Implementing an asteroid field, with Asteroids that rebound off each other, using elastic collisions to simulate realistic changes in direction and speed

• Creating manager classes for shots, the player's star fighter, and enemy ships

• Designing an Enemy class that can follow a set of waypoints as the ships traverse the screen

• Building an EnemyManager that controls enemy spawn rates and establishes waypoint paths for enemies to follow, as well as controlling enemy fire at the player

In Chapter 5, Asteroid Belt Assault – Special Effects, we will finish building the Asteroid Belt Assault game, by adding a collision management system...
