To begin with, the book will guide you through an introduction of the HTML5 canvas and some of the functionality that it provides to web and games developers. With an understanding of the HTML5 canvas, the book then gears its attention towards the creation of the 2D platform game in question by guiding you through the steps required to implement a basic game framework for any 2D HTML5 game.
The book will then progress iteratively through a number of components you might find within a 2D platform-based game. These components include monitoring and updating user input through means of a keyboard. Also covered are implementing a parallax background, adding enemies, and collectible items similar to the concept behind the coins in Mario and gold rings in Sonic. We will also look at implementing a basic form of physics, which will be used to allow the player to jump as well as introducing sound effects to the game to enhance its appeal.
Setting up your HTML5 canvas (Should know) gives an overview of how to set up the HTML5 canvas as well as some of the basic functionality the canvas has to offer and how we would go about implementing that functionality.
Implementing the game framework (Should know) is a step-by-step guide to the creation of a basic 2D game framework that takes advantage of polymorphism and which will be incrementally improved in each of the recipe. This framework will be responsible for updating and rendering game objects.
Creating the player (Must know) will look at the steps taken to implement a player class that will fit seamlessly with our game framework in order to load and draw the necessary assets to the canvas.
Handling user input (Must know) will improve upon the game framework introduced in an earlier task as well as enhance our player class to respond to the user's input. By responding to the user's input, we can move our player freely around the canvas.
Animating the player (Must know) will introduce an animation manager, which will allow us to load and render sprite sheet animations. We will also adjust the player class to take advantage of the animation manager so that we can animate the player.
Creating the level (Must know) will introduce...
