Book Structure

  • Chapter 1, Creating a Word Guessing Game, shows you how to create a simple word guessing game where the player has to find the letters that make-up a word chosen at random. You will learn to create a user interface for the game, to read words from a text file, and to pick one word from the file randomly. You will also learn how to process the player's input.
  • Chapter 2, Creating a Memory Game, shows you how to create a game where the player has to memorize and play an increasing sequence of colors and sounds, in a similar way as the Simon game that was popular in the 80s. You will learn how to create and generate audio within Unity and change sounds' frequency, to detect when a player has pressed a button, to generate colors at random, and also to record the sequence entered by the player and then compare it to the correct sequence.
  • Chapter 3, Creating a card Guessing Game, shows you how to create a card game where the player has to match and to memorize their location. You will learn how to change the texture of a sprite at run-time, check when two cards picked by the player are similar, and also how to shuffle cards.
  • Chapter 4, Creating a Puzzle Game, shows how to create a puzzle game where the player needs to move pieces in the right location to complete a puzzle. Along the way, you will learn how to slice an image into several sprites (i.e., pieces) to create puzzle pieces from an image of your choice, and how to shuffle these puzzle pieces; you will also learn how to make it possible for the player to move (i.e., drag and drop) these pieces, to make these pieces 'snap' to a particular location, and to detect when the player has dragged and dropped a piece to the correct location.
  • Chapter 5 provides answers to Frequently Asked Questions (FAQs) related to the topics covered in this book.
  • Chapter 6 summarizes the topics covered in the book and provides you with more information on the next steps.
