## Step 1: Setting up the environment + Open your favorite code editor (e.g. Visual Studio Code). + Create a new HTML file and name it "index.html". + Create another file and name it "script.js". ## Step 2: Basic HTML structure ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Simple JavaScript Game</title> </head> <body> <canvas id="gameCanvas" width="800" height="600"></canvas> <script src="script.js"></script> </body> </html> ``` ## Step 3: Developing JavaScript ```js // 1. Get the canvas element const canvas = document.getElementById('gameCanvas'); const ctx = canvas.getContext('2d'); // 2. Define variables let x = canvas.width / 2; let y = canvas.height - 30; let dx = 2; let dy = -2; const ballRadius = 10; // 3. Function to draw the ball function drawBall() { ctx.beginPath(); ctx.arc(x, y, ballRadius, 0, Math.PI * 2); ctx.fillStyle = "#0095DD"; ctx.fill(); ctx.closePath(); } // 4. Main drawing function function draw() { ctx.clearRect(0, 0, canvas.width, canvas.height); drawBall(); // 5. Update ball position x += dx; y += dy; // 6. Check for collisions with edges if (x + dx > canvas.width - ballRadius || x + dx < ballRadius) { dx = -dx; } if (y + dy > canvas.height - ballRadius || y + dy < ballRadius) { dy = -dy; } } // 7. Main game loop function mainLoop() { draw(); requestAnimationFrame(mainLoop); } // 8. Start the game mainLoop(); ``` **The result**: ![result](https://i.imgur.com/x9bJMV7.png) In this simple example I've created a game where a ball moves inside a canvas and bounces off the edges. You can add features such as player control, collisions with other objects, points, etc. Remember that this is a tutorial for javascript beginners. Have fun creating your own game!
