How to Create a Bouncing Ball Game with HTML, CSS, and JavaScript166

Introduction

Creating interactive games using web technologies like HTML, CSS, and JavaScript can be a fun and rewarding experience. In this tutorial, we'll explore how to create a classic bouncing ball game using these technologies.

HTML Structure

Let's start by defining the HTML structure of our game:```html



Bouncing Ball Game

```

: This container will house the game canvas.
canvas#canvas: This canvas element will serve as the drawing surface for our game.

CSS Styles

Next, we'll define some CSS styles to set the game's layout:```css
body {
background-color: #000;
margin: 0;
padding: 0;
}
.container {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}
canvas {
width: 500px;
height: 500px;
background-color: #fff;
}
```

We set body to have a black background and no margins/paddings.
.container is centered both horizontally and vertically.
Our canvas has a fixed size of 500x500 pixels and a white background.

JavaScript Functionality

Now, let's dive into the JavaScript code:```javascript
const canvas = ("canvas");
const ctx = ("2d");
// Ball object
const ball = {
x: / 2,
y: / 2,
radius: 10,
speedX: 5,
speedY: -5,
};
// Draw function
function drawBall() {
(0, 0, , );
();
(ball.x, ball.y, , 0, * 2);
= "#FF0000";
();
}
// Update function
function updateBall() {
// Check if ball has hit the left or right wall
if (ball.x + > || ball.x - < 0) {
= -;
}
// Check if ball has hit the top or bottom wall
if (ball.y + > || ball.y - < 0) {
= -;
}
// Update ball's position
ball.x += ;
ball.y += ;
}
// Game loop
function gameLoop() {
drawBall();
updateBall();
requestAnimationFrame(gameLoop);
}
gameLoop();
```

We define a ball object with initial position, radius, and speed.
drawBall draws the ball on the canvas using canvas context methods.
updateBall checks for collisions with the canvas edges and updates the ball's position.
The gameLoop function repeatedly calls drawBall and updateBall to create the animation.
requestAnimationFrame is used to run the game loop smoothly.

Conclusion

Congratulations! You've successfully created a bouncing ball game using HTML, CSS, and JavaScript. This tutorial provides a solid foundation to explore more complex game development concepts in the future.
