We have put a lot of interesting pieces together in this game. We have dynamic terrain, randomized enemies, shooting, jumping, endless backgrounds, and (hopefully) some fun while building and playing it. You will notice that there are a few less interesting bits we have not covered in depth. Please, consult the code bundle to explore the other pieces of the game, like the "Dramatic Entrance" when the hero starts the game by being dropped off by a space ship. There is also some helpful debugging code we used for the sensors (commented out) in the bottom of the ERPlayfieldLayer.m
file. By enabling that code, you can see the sensor boxes drawn while the game is playing.
It is our sincere hope that these projects have instructed, entertained, and perhaps even inspired you in your own pursuits. Each of the games, designed with a "bare bones" approach, gives plenty of room for exploration and expansion. If you create something wonderful as a result of having been inspired by these projects...
