This quiz will assess your knowledge of the skills and concepts learned in Unit 1.

Create with Code Lite Unit 1 - Driving Game

Navigate 3D space and the Unity Editor comfortably

Add and manipulate objects in the scene to position them where you want, including the camera

Control the layout of Unity Editor to suit your needs

Create C# scripts and apply them to objects

Use Visual Studio and a few of its basic features

Add Rigidbody and Collider components to allow objects to collide realistically 

Declare variables properly and initialize/assign them with appropriate access modifiers

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

The Hierarchy window contains a list of every GameObject in the current Scene. As objects are added and removed in the Scene, they will appear and disappear from the Hierarchy as well.

True or False: Visual Studio is not a part of Unity. You could use a different code editor to edit your C# scripts if you wanted to.

True. Visual Studio is just one of many editors you could use to edit your code, including editors like Atom, Sublime, or even a basic Text Editor.

What best describes the difference between the below images, where the car is in the second image is further along the road?

You can tell which axis the car has moved along using the XYZ directional gizmo in the top-right, which shows the blue axis pointing forwards down the road.

In what order do you put the words when you are declaring a new variable? 

Variables are always declared in the order: 

[access modifier] - public, private, etc 

[data type] - float, int, GameObject, etc 

[variable name] - speed, turnSpeed, player, offset, etc 

[variable value] - 1.0f, 2, new Vector3(0, 1, 0), etc

 Which of the following variables would be visible in the Inspector?

“public float speed” would be visible because it has the “public” modifier applied to it

 What is a possible value for the horizontalInput variable?

Input.GetAxis returns a float value between -1 and 1, which means 0.52 is a possible value

 What is true about the following two lines of code?

Vector3.forward is the equivalent of (0, 0, 1), which has the same magnitude as (1, 0, 0), even though they’re in different directions, so they would both move an object the same distance, but along different axes

 Which of the following lines of code is using standard Unity naming conventions?`

“public float speed = 40.0f;” uses the correct naming conventions because all three of these terms should start with lowercase letters

 Which comment would best describe the code below?

Vector3.up is the Y axis and it’s using the Horizontal input value, so it would rotate around the Y axis when the user presses the left/right arrows

 The image below shows the preferences window that allows you to change which script editing tool (or IDE) you want to use. Where would you click to choose an alternative code editing tool?

You would click on the Red box to change the “External Script Editor” from Visual Studio to another tool.
