During Christmas vacation of 1999, I wrote a game which was inspired by Astrosmash!
for the Mattel Intellivision, itself inspired by the classic Atari game "Asteroids". Rocks! has 6
progressively more difficult stages, 4 unique enemies, and two different modes of
game play: "floating" in which your ship can move freely about and enemies come from all sides,
and "falling" in which you are confined to left-right movement on the ground and enemies come from
the top of the screen. This is a good example of my OOP graphics library I had developed in the
early 90s, my recently acquired understanding of trigonometry and physics, my high-speed bitmap
scaling and rotation routines, and a simple sound effects engine which works on three different
sound cards (Adlib, SoundBlaster, and the Gravis Ultrasound).
|EXAMINE YOUR CONTROLS|
Here are the keys used to control your ship, change the volume, and pause or exit the game:
|KEYPAD +||Increase volume||KEYPAD -||Decrease volume|
|ENTER||Pause game||A||Toggle Auto-fire On/Off|
|RIGHT ARROW||Rotate ship clockwise||LEFT ARROW||Rotate ship counter-clockwise|
|UP ARROW||Thrust||DOWN ARROW||Counter-thrust|
