Mapping Object Oriented Principles to C# with Unity & Syntax


In Unity, when using C# to create your game, you will be writing statements and creating new classes in C# following an object-oriented programming syntax.

School Bundle (i.e., site license) ending this Thursday

From September onward, a “School Bundle” will be made available to schools and universities; the idea is to make the books and videos more accessible to students.

As a teacher, you will be able to enroll your class or school to the “School Bundle”; all students will then have access to all my books (the ones that I have published) in pdf format, as well as all the videos currently available on plus any additional course or video, for 12 months.

Creating a simple word game

In this section, we will create a word guessing game with Unity, with the following features:

  • A word will be picked at random from an existing list.
  • The letters of the word will be hidden.
  • The players will try to guess each letter by pressing a letter on their keyboard.
  • Once a letter has been discovered it will then be displayed onscreen.
  • The player has a limited number of attempts to guess the word.

So, after completing this tutorial, you will be able to:

  • Read words from a text file.
  • Pick a random word.
  • Process and assess the letters pressed by the player.
  • Display the letters that were correctly guessed by the player.
  • Track and display the score.
  • Check when the player has used too many guesses.
