Development

Player

• Four different sprites are used for simple animation: turn left, right, gas on and idle

• Two particle systems are used for exhaust effect: one smoke, one flame

  • Particle systems size now scales with user input when gas is pressed / released

• Player bullets collide with: enemies, meteors and enemy bullets
  
  

  • Explosions: Player now explodes on death. 4 pieces were matched to our ship's hex colors: white, green, blue. These four pngs now spawn, each with a random size when the ship explodes

Enemies

• Enemies move and rotate toward player
• Enemies shoot their own bullets in same direction as current global direction at a very slow rate
  
  
  • Bullets: Bullet sizes are now dynamic, scaling with each respective enemies random initialization size. A bigger random size during initialization causes bullet scale to also have a larger range during initialization

Meteors and Enemies

• Meteors now spawn with a random direction: left-up, left and left-down and a random rotation and keep these values for the full duration of their lifetime

Randomization:

• Random speed
• Enemies and meteors now spawn from 5 different random initial initialization positions. Spawn time or amount aloud at one time is controlled by each of their respective timers in the game scene
• Four enemy colors: green, blue, red, orange

Explosions:

• Enemies and meteors now explode on death.
• Explosion sizes (enemy and meteor) are now dynamic Scales with enemy or meteor random initialization size. A bigger random size during initialization causes a greater chance of the explosion containing larger scaled pieces
• Enemy explosion colors are now dynamic, matching their parent’s random initialization color index: 1, 2, 3 or 4
