Carl wants to add two new characters to the extraterrestrial battleship game he's building in order to have multiple players battling each other. This not only helps him create engagement for users, but it adds excitement to his recreational game. One character is a water-based alien with only one eye and 8 legs, resembling the features of an octopus. The second character is a land-based alien with no eyes, 3 claws, and 3 legs, resembling the features of a crab. Which is the best explanation why there is only one class with the new characters?

• A game can have multiple instances using the same class.

• A game can have multiple functions under one class.

• A game must have the same values under one class.

• A game can have multiple properties under one instance.

Answer explanation

A class is a definition or blueprint used to create a particular type of object. A class provides a detailed description of the object's characteristics (such as that the object should include a size and a color), and it specifies what can be done with the object (its functions). When a class is used to build an object, the object is called an instance of the class. Multiple objects (or instances) can be created using the same class. Instances are represented by their class and properties. Properties are the various characteristics of an object, such as size, color and type. Each object created using the class contains the same properties, but the values of the properties may be different.

Which of the following scenarios would cause an error?

• Three students in class

• Zero students in class

• No error would occur

• 
  

  Ten students in class

Answer explanation

The algorithm does not consider an odd number of students and will not correctly calculate the actual number of students.

The game developer and the game designer are meeting to discuss the addition of new characters to the "Animal Hunt" game that has been created. But, both individuals are unsure of where to include the addition of the Rhino, T-Rex, and Fox characters. The team decides to look back at the storyline and the different scenes created to see where these new characters best fit in the game. What storyline document is the developer and game designer referring to?

• 
  

  Feedback

• 
  

  Prototype

• Storyboard

• Wireframe

Answer explanation

A storyboard is like a graphic organizer that uses illustrations or images displayed on a piece of paper or created in software. The images are arranged in the order of the story and help the team plan the sequence of events – every step – in the game's animation. A storyboard helps with identifying how the characters interact with each other and with the game environment.

This is an example of which type of programming structure?

• 
  

  Iteration

• Object

• Selection

• Looping

Answer explanation

A selection program structure allows the computer to make a selection between alternative conditions (for example, if this condition exists, do this—if not, do that).

Why is this an example of a Boolean concept?

• The pseudocode contains operators that follow logic.

• 
  

  The pseudocode uses stored data.

• The pseudocode contains conditions that are either true or false.

• The pseudocode contains expressions that follow an order of precedence.

Answer explanation

A Boolean (true or false) contains a condition and is often used in repetition and selection structures.

Which term describes this example?

• A flow chart

• A class

• An object

• 
  

  An algorithm

Answer explanation

An algorithm is a set of step-by-step instructions that must be executed in order to solve a problem or perform a task.

Your co-worker has just completed developing the first phase of an action-based game prototype, but needs some feedback on the level of difficulty. You test the product, yet encounter many bugs (inconsistencies) in the game's storyline. What is the best way to help your co-worker solve the problem?

• Provide a list of errors in the game.

• Retest the game once your co-worker has revised it and fixed the bugs.

• 
  

  Review the game's storyboard to see if the sequence of events matches the prototype and how each character or element interact with each other.

• Meet with your co-worker to find out more information about the game prototype in order to assess the problem.

Answer explanation

Create a storyboard - A storyboard is like a graphic organizer that uses illustrations or images displayed on a piece of paper or created in software. The images are arranged in the order of the story and help the team plan the sequence of events - every step - in the game's animation. A storyboard helps with identifying how the characters interact with each other and with the game environment.

What is the first step in the game design process?

• Brainstorm ideas.

• Create a prototype.

• Gather feedback.

• Create a storyboard.

Answer explanation

The game design process steps are:

1. brainstorm ideas for games

2. create a storyboard

3. create a prototype

4. test and gather feedback

5. revise the game

6. re-test and gather feedback

7. finalize the game

8. revise and re-test (if necessary)

Harry learned how to design and build computer games from his programming foundations class in college and wants to tackle creating his first mobile app game. What essential tools does Harry need if he already has the skills?

• 
  

  A storyboard, computer hardware, music and sound effects, and programming code.

• Programming code, game engine software, and game design.

• A computer hardware, game engine software, graphical art design application, and programming code.

• A mobile tablet, game engine software, and programming code.

Answer explanation

Computer hardware—Desktop computers, tablets and handheld devices all work—designers should choose the tools they feel most comfortable working with (small vs. large screen, keyboard vs. touchscreen, and so forth). Software—There are many applications you can use to create games. Some only run program code, others help you animate art, and some will do almost everything for you. Graphical art—Video games consist of graphics in motion with a goal and a plan. Programming—Programming code is required to create a computer game.

Lesson

The marvelous attribute about the gaming industry is that you can create a game in several different programming languages to make it more appealing to novice and advanced-level coders. Yet, the unique distinction is that every single programming language has its own ____________?

• commands

• syntax

• 
  

  language

• structure

Answer explanation

Programmers write instructions as a series of statements using the code and syntax for a particular programming language. Each programming language has its own syntax rules. Some of the different languages used to write games include C++, .NET, Java and others. Program developers choose the programming languages they will use based on which platform and device the program will be using, such as Windows, Mac, Android or iOS.
