Create a Simple HTML Tetris Game: Step-by-Step Guide

This guide will walk you through the process of creating a simple Tetris game using HTML, CSS, and JavaScript. Let's get started!

Instructions

Create an HTML file: Open a text editor and create a new HTML file (e.g., 'tetris.html').

Set up the game container:

Inside the HTML file, create a <div> element with the ID 'tetris'. This will be the main container for your game.
Within the <div>, add a <canvas> element with the ID 'tetrisCanvas'. This is where the game will be drawn.

<!DOCTYPE html>
<html>
<head>
    <title>Tetris Game</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div id="tetris">
        <canvas id="tetrisCanvas"></canvas>
    </div>
    <script src="script.js"></script>
</body>
</html>

Add CSS styling:
- Create a separate CSS file (e.g., 'style.css') to style your game.
- Style the <div> and <canvas> elements to create the desired look for your game board.
Link the JavaScript file:
- Create a JavaScript file (e.g., 'script.js') to handle the game logic.
- Link this file to your HTML file using the <script> tag.
JavaScript Game Logic:
- Constructor function: Create a constructor function in your JavaScript file to initialize the game state, such as the canvas size and other settings.
- draw() function: Create a function to draw the game on the canvas. This should include the playing field, blocks, and other game elements.
- Block generation: Implement a function to generate random blocks and place them on the playing field.
- Block movement: Create a function to move the blocks based on user input (key presses).
- Row completion: Implement a function to detect when a row is complete and remove it from the playing field.
- Win/loss detection: Create a function to determine if the game has been won or lost.
- start() function: Create a function to start the game.
- Event listener: Add an event listener to the document that listens for key presses and calls the appropriate function to move the blocks.
- Start the game: Call the start() function to begin the game.

Remember to fill in the details for each function based on your specific game design and requirements.

This guide provides a basic framework for building a Tetris game. You can expand upon this by adding features like scoring, levels, different block shapes, and more!
