HTML5 Canvas Snake Game
Introduction
Snake game is one of the oldest and most popular video games of all time. It was first introduced in the 1970s, and since then, it has been a favorite of many gamers around the world. With the advent of HTML5, we can now build the snake game using Canvas, which is a powerful tool that allows us to create dynamic, interactive, and visually appealing games.
In this article, we will explore how to build a snake game using HTML5 Canvas. We will go through the step-by-step process of building the game, including creating the game board, drawing the snake and the food, controlling the snake’s movement, and detecting collisions.
Getting Started
Before we dive into the actual code, we need to set up our environment. For this tutorial, we will be using a simple HTML file, a CSS file, and a JavaScript file. We will also be using the Canvas API, which is built into the HTML5 specification.
The HTML file will contain the basic structure of our web page, including the Canvas element, which will be used to draw the game. The CSS file will be used to style our web page, and the JavaScript file will contain the code for our game.
Creating the Game Board
The first step in building our snake game is to create the game board. We will use the Canvas API to create a Canvas element and set its dimensions to match the size of our game board. We will also set the background color of the Canvas to black.
php
Copy code
<canvas id=”game-board” width=”400″ height=”400″></canvas>
<style>
canvas {
background-color: black;}</style>
Drawing the Snake
Now that we have our game board set up, we can start drawing the snake. The snake will be represented by a series of squares, and we will use the Canvas API to draw these squares.
To draw the snake, we will create an array of objects, where each object represents a square of the snake. Each object will contain the x and y coordinates of the square’s position, as well as its width and height.
yaml
Copy code
const snake = [
{x: 10, y: 10, width: 10, height: 10},
{x: 20, y: 10, width: 10, height: 10},
{x: 30, y: 10, width: 10, height: 10}
];
We will also create a function called drawSnake that will be responsible for drawing the snake on the Canvas. The drawSnake function will loop through the snake array and draw each square on the Canvas using the fillRect method.
scss
Copy code
function drawSnake() {
for (let i = 0; i < snake.length; i++) {
const square = snake[i];
context.fillStyle = ‘white’;
context.fillRect(square.x, square.y, square.width, square.height);}}
Controlling the Snake’s Movement
Now that we have the snake drawn on the Canvas, we need to add some interactivity to the game. We will do this by allowing the player to control the snake’s movement using the arrow keys on their keyboard.
To do this, we will create a function called moveSnake that will update the position of the snake’s head based on the direction that the player has chosen. We will also add an event listener to the document that listens for arrow key presses and updates the direction of the snake accordingly.
javascript
Copy code
let direction = ‘right’;
function moveSnake() {
const head = snake[0];
switch (direction) {
case ‘up’:
head.y -= 10;
break;
0 0 0.
