JavaScript Snake tutorial

JavaScript Snake tutorial shows how to create a Snakes game in JavaScript. The images and sources are available at the author’s Github JavaScript-Snake-Game repository.

Snake game

Snakes is an older classic video game which was first created in late 70s. Later it was brought to PCs. In this game the player controls a snakes. The objective is to eat as many apples as possible. Each time the snakes eats an apple, its body grows. The snakes must avoid the walls and its own body. This game is sometimes called Nibbles.

HTML5 Canvas

HTML5 canvas element provides a resolution-dependent bitmap area, which can be used for rendering graphs, game graphics, art, or other visual images on the fly. In simple terms, canvas is a new element in HTML5, which allows you to draw graphics using JavaScript. Canvas brings animations to web pages without the need of plugins like Flash, Silverlight, or Java.

JavaScript Snake code example

The size of each of the joints of a snakes is 10 px. The snakes is controlled with the cursor keys. Initially, the snakes has three joints. If the game is finished, the “Game Over” message is displayed in the middle of the canvas.

A snakes game is a simple game where a snakes moves around a box trying to eat an apple. Once it successfully eats the apple, the length of the snake increases and the movement becomes faster.

Then the game is over when the snakes runs into itself or any of the four walls of the box.

Alright, let’s start with the HTML and CSS (the skeleton for our game).

The HTML above is pretty basic.

We have a div of class scoreDisplay that will display our scores.
There’s a div of class grid that will house the game (this is going to be a 10 by 10 grid)
The class button basically contains a button for users playing the game on a phone (we will automate it with the keyboard for desktop user).
And the popup class will hold our replay button.
Now let’s add some styling with CSS.

In the CSS, the grid which is the gameboard has a set dimension and a display of flex. This allows the contents (div) of this grid to line up in a horizontal manner as if they were inline elements instead of the normal block display which they possess.

The flex wrap property simply moves the divs to the next line, preventing them from going past the set dimension of their parent element (grid).

We will be dynamically creating the game board contents from JS but we can give a width and height here (with the .grid div). I included the comments here to help you actually see the divs, so as time goes on we will uncomment the code.

The snakes and Apple classes are to show us where the snake and bonus is on the game, while the popup class is a fixed div that houses the replay div.

At this point, you should have something like this:
