In this example we will look at slicing images with the drawImage() method of a 2d canvas context. We’ll use two images that are larger than the canvas to create a parallax scrolling effect that is common in 2d games and also another image as a spritemap consisting of three sprites to show how to slice out and draw individual sprites.

I made this example as simple as possible to keep from cluttering up the key concepts of slicing and drawing pieces of images on the canvas. It only moves in one direction by pressing the right arrow key on your keyboard.

Let’s make a maze game in an HTML5 canvas. In this post Moving Shapes on the HTML5 Canvas With the Keyboard we learned to use keyboard input to move a shape around the canvas. All we need to do to make our game is

1. Add an image of the maze to the canvas.

2. Add collision detection code so we know if our shape hits a border in the maze.
