Chapter 2. Adding Interactivity – The Making of a Concentration Game
By definition, a game is interactive in some way. Players have to be part of it by doing things. The simplest form of interactivity is clicking or touching tiles in the game.
A Concentration game is simple to explain, but it will cover some new and important concepts, such as:
- Creating multiple instances of game assets
- Extending classes to improve its capabilities. Actually, there are no classes in JavaScript, but they are emulated using variables and prototypes
- Adding gradients
- Making assets react to clicks and touches
- Changing sprite images on the fly
- Adding text labels
- Removing sprites from the game
By the end of the chapter, you will be able to create a full Concentration game using space for customization.
As the project created in the previous chapter is more than just a Hello World game and rather acts as a blueprint for all your future projects, you'll start building our Concentration game out of the previously finished project.
