Asteroids

Objectives

• You will create a game that mimics gameplay of Asteroids
• The player will be able to move around using the keyboard
• The player's ship will be affected by momentum and physics
• The player will be able to fire at asteroids and break them apart
• The player will be able to aim using the mouse
• Points will be given to the player for destroying asteroids

Requirements

Ship Movement

• The ship should always point towards the mouse
• Pressing the W-key will accelerate the ship and go forwards
  1. Create a speed variable and set it to 0
  2. If the W-key is pressed, then increase speed by a little bit (e.g. 0.5)
  3. Else, if speed is greater than 0, then decrease speed by a little bit (e.g. -0.5)
  4. Move the ship speed steps
• Pressing the S-key will decelerate the ship and go backwards
  • Follow the same steps as the W-key, but reverse/negate everything

Firing Projectiles

• Pressing the mouse down will fire a projectile (use clones)
  • The projectile should disappear when it hits the edge of the screen
  • If the mouse is held down, a projectiles (clones) should be fired every 0.5 second

Asteroids

1. Make an asteroid appear at a random edge of the screen
   1. Pick a random number between 1-4 (each number corresponds to a side)
   2. Pick a random place for that side and tell the asteroid to appear there
   3. Give it a random direction (these will depend on which side the asteroid is located
2. Have it move across the screen
