Game Design and Programing Semster Review Part 1

Front

Which window contains a list of all the game objects in your scene?

Back

hierarchy

Answer explanation

The hierarchy window displays all game objects in your scene, allowing you to manage and organize them. The project window shows assets, while the inspector provides details about the selected object.

Front

Visual Studio is a part of Unity and the only code editor we can use.

Back

False

Answer explanation

The statement is false because Visual Studio is not the only code editor that can be used with Unity. Other editors like JetBrains Rider and Visual Studio Code are also compatible.

Based off of this picture what would change to show another car moving ahead? Options: The second car’s X location value is higher than the first car’s, The second car’s Z location value is higher than the first car’s, The second car’s Transform value is higher than the first car’s, The second car’s Y location value is higher than the first car’s.

Back

The second car’s Z location value is higher than the first car’s.

Answer explanation

To show another car moving ahead, its Z location value must be higher than the first car's. The Z-axis typically represents forward movement in 3D space, making this the correct choice.

Front

How would we say this in words: private float horizontalInput;

Back

access modifier, data type, variable name

Answer explanation

The correct choice is 'access modifier, data type, variable name' because 'private' is the access modifier, 'float' is the data type, and 'horizontalInput' is the variable name. This order accurately describes the components of the declaration.

Front

Which variable would be visible in the Inspector? Options: turnSpeed, speed, speed and turnSpeed, horizontalInput

Back

speed

Answer explanation

The variable 'speed' is visible in the Inspector because it is likely marked for visibility, while 'turnSpeed' and 'horizontalInput' may not be. Therefore, 'speed' is the correct choice.

Front

What could be a value for the horizontalInput variable? horizontalInput = Input.GetAxis("Horizontal");

Back

.45

Answer explanation

.45 is a valid value for horizontalInput as it represents a float between -1 and 1, which is the expected range for Input.GetAxis. The other options are not valid inputs for this function.

Front

Based on the the code; they will both move the object in the same direction.

Back

False

Answer explanation

The statement is false because the code may have different parameters or conditions that affect the direction of movement, leading to the possibility that they do not move the object in the same direction.

Front

Which of the following is the correct way to code in Unity?
Options: Private Float ForwardInput;, private float forwardInput;, private float forwardinput;, private float forwardInput

Back

private float forwardInput;

Answer explanation

The correct choice is 'private float forwardInput;' because it follows C# naming conventions: 'private' and 'float' are in lowercase, and 'forwardInput' uses camelCase. The other options have incorrect casing or syntax.

Front

Which comment describes the code in the image? Options: // Rotates around the Z axis based on up/down arrow keys, // Rotates in an upward direction based on left/right arrow keys, // Moves object up/down based on the the left/right arrow keys, // Rotates around the Y axis based on left/right arrow keys

Back

// Rotates around the Y axis based on left/right arrow keys

Answer explanation

The correct comment indicates that the code rotates the object around the Y axis when the left/right arrow keys are pressed, which aligns with the expected behavior of such controls in 3D environments.

Front

What is the purpose of Visual Studio in Unity?

Back

To write and edit C# scripts

Answer explanation

Visual Studio is primarily used in Unity to write and edit C# scripts, which are essential for game functionality and behavior. The other options, such as composing music or creating models, are not its main purpose.
