Asteroids

The classic asteroids game, for Arduino!

This was a CMPUT274 final project by Songhui Zhang & James Hryniw

Accessories:

• 1x Arduino MEGA board
• 1x Adafruit ILI9341 Breakout Board
• 1x SainSmart JoyStick Module
• 2x Push buttons

Wiring instructions:

Adafruit (Left is Adafruit, right is Arduino)

• GND <> GND
• Vin <> 5V
• CLK <> 52
• MISO <> 50
• MOSI <> 51
• CS <> 10
• D/C <> 9
• Y+ <> A2
• X+ <> 4
• Y- <> 5
• X- <> A3
• CCS <> 6

Joystick (Left is joystick, right is Arduino)

• GND <> GND
• +5V <> 5V
• VRx <> A1
• VRy <> A0
• SW <> 2

Buttons

• Button 1 + <> 13
• Button 2 + <> 12
• Button 1 - <> GND
• Button 2 - <> GND

Program instructions:

• Wire Arduino as above and connect it to the computer.
• In terminal, navigate to program directory and enter "make upload".
• The joystick controls the direction of the ship.
• Pressing and holding button 1 will accelerate the ship.
• Pressing button 2 will shoot a bullet.
• Shooting an asteroid with a bullet will increase your score and may spawn two smaller asteroids.
• Colliding the ship with an asteroid will cause you to lose one life and respawn in the center of the screen. You will be invulnerable for two seconds afterwards.
• Losing all three lives will end the game. Press the Arduino's RESET button to restart the game.

Code structure:

• Asteroid, Bullet, and Spaceship are similar physics objects
• These are updated and created by GameState
• main() updates GameState with delta time and handles Asteroid spawn
• inputs and common are misc. files to handle input and game logic respectively.
• The program assumes that the joysticks are calibrated similarly.
