index.html has been created. Now, let's start building the game. Here's a basic structure for your index.html file: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Alien Shooter</title> <style> /* Add your CSS styles here */ </style> </head> <body> <script src="phaser.min.js"></script> <script> // Add your JavaScript code here </script> </body> </html> ``` Now, let's start adding the game functionality. We'll begin by setting up the Phaser game and creating the basic player and alien classes. I'll write the code for you, and then we can proceed with adding more features like alien waves and player movement. Here's the initial JavaScript code to set up the game: ```javascript const config = { type: Phaser.AUTO, width: 800, height: 600, physics: { default: 'arcade', arcade: { gravity: { y: 0 } } }, scene: { preload: preload, create: create, update: update } }; const game = new Phaser.Game(config); let player; let aliens = []; function preload() { // Load assets here (if any) } function create() { this.input.keyboard.createCursorKeys(); player = this.physics.add.sprite(400, 300, 'player'); player.setBounce(0.2); player.setCollideWorldBounds(true); // Add alien creation and movement here } function update(time, delta) { // Add game update logic here } ``` I'll write this code into the index.html file. Next, we'll add player movement using the WASD keys and create a simple alien class for the advancing aliens. We'll also implement basic health and scoring systems. Finally, we'll add increasing difficulty by spawning more aliens over time. Let's start by writing the initial code into the index.html file. ```python code = """<script> const config = { type: Phaser.AUTO, width: 800, height: 600, physics: { default: 'arcade', arcade: { gravity: { y: 0 } } }, scene: { preload: preload, create: create, update: update } }; const game = new Phaser.Game(config); let player; let aliens = []; function preload() { // Load assets here (if any) } function create() { this.input.keyboard.createCursorKeys(); player = this.physics.add.sprite(400, 300, 'player'); player.setBounce(0.2); player.setCollideWorldBounds(true); // Add alien creation and movement here } function update(time, delta) { // Add game update logic here } </script>""" with open("index.html", "w") as f: f.write(html_code) ```
