How To Get To Canvas Game

Creating a Canvas game is an exciting opportunity for game development and can be a simple way to begin. The introduction of the ‘canvas’ element in HTML5 has greatly improved web graphics. This step-by-step guide will assist you in setting up a basic Canvas game.


To follow along with this tutorial, you will need a basic understanding of HTML, CSS, and JavaScript. You might also need a text editor such as Sublime Text, Atom or Visual Studio Code, and a modern web browser for testing purposes.

Setting Up the HTML

Let’s start by setting up the HTML structure for our game. We will create a ‘canvas’ element and assign it an ‘id’ so we can easily target it with JavaScript later.

<!DOCTYPE html>
  <title>My Canvas Game</title>
  <canvas id="gameCanvas" width="800" height="600"></canvas>

Here, we created a <canvas> element with an id of ‘gameCanvas’ and set its width and height to 800 and 600 pixels, respectively.

Getting a Reference to the Canvas

Now, let’s get a reference to the canvas from our JavaScript code. We do this using the document.getElementById() function.

let canvas = document.getElementById('gameCanvas');
let context = canvas.getContext('2d');

In the first line, we get a reference to the canvas element. The second line gets the rendering context we’ll use for drawing on the canvas. The ‘2d’ context allows us to draw 2D shapes.

Drawing on the Canvas

Once we have the context, we can start drawing on the canvas. Let’s start by drawing a simple rectangle.

context.fillStyle = 'blue';
context.fillRect(30, 30, 50, 50);

The first line sets the color that will be used to fill the rectangle. The second line draws a rectangle at position (30, 30) with a width and height of 50 pixels.

This is just a basic introduction to creating a Canvas game. With these fundamentals, you can start to explore more complex shapes, animations, and even user interactions to develop your very own game. Happy coding!
