What will be the result of the code below?

public class Enemy : MonoBehaviour
{
    public Transform ground;

    void Update()
    {
        if (transform.position.y < ground.position.y)
        {
            Destroy(gameObject);
        }
    }
}

What will be the result of the code below?  public class Enemy : MonoBehaviour
{
    public Transform ground;

    void Update()
    {
        if (transform.position.y < ground.position.y)
        {
            Destroy(gameObject);
        }
    }
}  

If the player goes beneath the ground, destroy the player.

If the player touches an enemy, destroy the player.

If an enemy goes above the ground, destroy the enemy.

If an enemy goes below the ground, destroy the enemy.

Since this is the Enemy class, Destroy(gameOjbect) will destroy the enemy. The if statement is testing whether the enemy’s y position is less than (or lower than) the ground’s y position. So the enemy will be destroyed if it goes below the ground.

What would be the appropriate line of code to replace the comment below? 

public float[] values = values[5];

void Start()
{
 // assign the first element in the array the value of 5.0
}

What would be the appropriate line of code to replace the comment below?   public float[] values = values[5];

void Start()
{
 // assign the first element in the array the value of 5.0
}  

In order to access an element in the array, you reference the name of the array, which is “values” followed by the index of the array element in square brackets. Since the first element of the array has an index of 0, it would be:
values[0] = 5.0f;

Which comment best describes the code below?

public class Player : MonoBehaviour
{
  // Comment
  private void OnTriggerEnter(Collider other) {
    if(other.CompareTag("Spike")) {
      Destroy(other.gameObject);
    }
  }
}

Which comment best describes the code below?  public class Player : MonoBehaviour
{
  // Comment
  private void OnTriggerEnter(Collider other) {
    if(other.CompareTag("Spike")) {
      Destroy(other.gameObject);
    }
  }
}  

// If the player collides with a spike, destroy the spike

// If the player collides with a spike, destroy the player

// If the enemy collides with a spike, destroy the enemy

// If the player collides with an enemy, destroy the enemy

Since this is the “Player” class, we are testing for the player colliding with something. Since it destroys “other.gameObject”, it will destroy the spike.

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 setting in box 1 to change the “External Script Editor” from Visual Studio to another tool.

In Visual Studio, “5.0f;” would be underlined with a red squiggly line. When you hover the mouse over the error, what do you think the message would say?

In Visual Studio, “5.0f;” would be underlined with a red squiggly line. When you hover the mouse over the error, what do you think the message would say?  int health = 5.0f;  

Cannot implicitly convert type ‘float’ to ‘int’.

Cannot complete statement. Remove semicolon.

The value “f” could not be interpreted for type ‘int’.

Since floats include decimals, and ints (integers) do not, it is not possible to assign a decimal value to an int variable. A float (with decimals) cannot be converted into an int.

Using the information shown in the autocomplete pop-up window below, which of the following would be a valid call of the Instantiate method?

Instantiate(objectPrefab.transform, spawner, true);

Instantiate(objectPrefab, spawner, false);

Instantiate(objectPrefab, spawner.transform, true);

Instantiate(objectPrefab, spawner, bool);

You can see from the tooltip that the Instantiate method can receive 3 parameters with types in the following order: Object, Transform, bool. That means that the first parameter can be an object (objectPrefab) the second can be a transform of an object (spawner.transform) and the third must be a bool value (e.g. true or false).

What would be the code required to produce the debug message shown below?

What would be the code required to produce the debug message shown below? Hello world.  

The correct method is Debug.Log, and any simple string messages like “Hello world.” must be enclosed in quotation marks.

Which of the following is true about either the Start() or Update() functions in a Unity Monobehavior class?

The Update() function runs only one time.

Player input should be handled in the Update() function.

The Start() function runs at the start of every Update() function.

The Update() function runs before the Start() function.

It would make no sense to handle player input in the Start() function, since it is only called once. It makes more sense to handle player input in the Update() function, which runs every single frame.

In what order do the parts of this script appear?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
 public float speed;
 public string playerName;

 void Start()
    {
        playerName = "Test";
    }

 void Update()
    {
        speed++;
    }

}

In what order do the parts of this script appear?  using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
 public float speed;
 public string playerName;

 void Start()
    {
        playerName = "Test";
    }

 void Update()
    {
        speed++;
    }

}  

namespaces, class declaration, variables, functions

functions, class declaration, namespaces, variables

class declaration, namespaces, functions, variables

variables, namespaces, functions, class declaration

The “using” statements refer to the namespaces, the line beginning with “public class” is the class declaration, the lines beginning with “public” are the variables, and the Start() and Update() sections are the functions.

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


Which of the following lines of code is using standard Unity naming conventions?
 Public Float Speed = 40.0f; Public float Speed = 40.0f; public float Speed = 40.0f; public float speed = 40.0f;  

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

Given the inspector shown below, showing variables for “Speed” and “Player Name,” which of the following lines of code would you expect to see in PlayerController.cs?

Since they are displayed in the inspector, the variables must include the “public” access modifier. Variables should also be camelcase and must not include spaces.
