Asteroids-2026/Software.md

Build Guidelines

Create an HTML Phaser 3 video game. This game will be a top down space shooter game, similar to Asteroids but with several modifications.

Tools and Organization

• Phaser version 3 HTML game
• Use Javascript
• Do NOT require a web packager. Have JS objects reference each other directly via IMPORT and EXPORT using ES6 standards

Basic Framework

• 1600 x 900 view
• Use termporary vector graphics that can later be replaced by sprites

Gameplay

• There should be multiple levels in this game.
  • A level ends when all asteroids and alien ships are destroyed.
  • When a new level begins, the player always begins in the middle of the screen.
• Asteroids spawn at the beginning of each level.
  • Asteroids rotate slowly in a random direction and a random low speed.
  • When Large Asteroids are shot and destroyed, they turn into either mid sized or small asteroids (between 1 and 3 total)
  • When mid sized asteroids are destroyed, they turn into two small asteroids.
  • When small asteroids are destroyed, they are completely destroyed.
• Periodically alien ships will attack.
  • They move towards the player's ship and fire occasionally.
  • WHen the alien ship is hit with a shot from the player, it is destroyed.

Controls

• Player's space ship follows the mouse cursor.
  • The space ship can only rotate to follow the mouse at the rate of 2 seconds to turn 360 degrees.
  • If the user moves the mouse the players ship will rotate automatically at this rate until it is pointing in the direction of the mouse cursor.
  • The left mouse button fires the accelerator for the space ship.
  • In all cases the space ship is in zero gravity.
    • It takes a couple seconds to get the ship to full acceleration.
    • If the player stops accelerating the ship continues to move in it's current direction until it decelerates.
  • The player can use the "a" key or "space" key to fire.
