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
- Create a speed variable and set it to 0
- If the W-key is pressed, then increase speed by a little bit (e.g. 0.5)
- Else, if speed is greater than 0, then decrease speed by a little bit (e.g. -0.5)
- 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
- A laser/firing sound should be played when a projectile is fired
Asteroids
- Multiple asteroids should appear on the screen doing the following:
- Make an asteroid appear at a random edge of the screen
- Pick a random number between 1-4 (each number corresponds to a side)
- Use if-statements to check for each number 1 through 4,
- Tell the asteroid to appear at a random place along that side (will be different for each side)
- Give it a random direction (depends on the side the asteroid is located)
- Have the asteroid move across the screen
- The asteroid should disappear when it hits another edge
Asteroid Collisions
- If asteroids collide with the ship, then it's game over
- Play a sound for the collision
- If projectiles hit the asteroids, then the asteroid should explode and points given to the player
- Play a sound for the explosion
Aesthetics
- Use a basic star field for the background
- Find simple background music to use -- something appropriate for the theme of the game
Advanced Requirements
- Other flying objects on the screen give different point values
- Large asteroids that explode break apart into smaller asteroids and the smaller ones can be fire upon for points
- Use a cloud variable for the high score
