Introduction to Unity Meetup 5

The code below executes in the enemy red ball's script. Which direction will the enemy move when its code below executes? (See live stream for enemy's and player's ball locations in space)

enemyRb.addForce(transform.position - player.transform.position));

• Toward player

• Away from player

[NEW] The code below is in the red ball's script, and we know the yellow ball moves at 1 meter per second. Will the red ball and the yellow ball move at the same speed? (See live stream for visualization of the red and yellow balls' position and speed)

transform.Translate((transform.position - player.transform.position)*Time.deltaTime)

• Yes they will move at the same speed

• No they will not move at the same speed

[NEW] The code below is in the red ball's script, and we know the yellow ball moves at 5 meters per second. Will the red ball and the yellow ball move at the same speed? (See live stream for visualization of the red and yellow balls' position and speed)

transform.Translate((transform.position - player.transform.position).normalized*Time.deltaTime*5)

• Yes they will move at the same speed

• No they will not move at the same speed

If I change the color of the prefab will it affect the instance as well?

• Yes

• No

If I change the color of the instance will it affect the prefab as well?

• Yes

• No

Which axis does the sphere move towards when it executes the code below? (See live stream for visualization of axes)

transform.Translate(transform.right);

• Global +X Axis

• Local +X Axis

Which axis does the sphere move towards when it executes the code below? (See live stream for visualization of axes)

transform.Translate(Vector3.right);

• Global +X Axis

• Local +X Axis

Match the following animation methods with its set of parameters(See live stream for listed options)

• 1A, 2B, 3C

• 1A, 2C, 3B

• 1B, 2A, 3C

• 1C, 2A, 3B

Which of these is the correct way to get a reference to an AudioSource component on a GameObject?

A. audio = GetComponent<AudioSource>();

B. audio = GetComponent(AudioSource)<>;

C. audio = AudioSource.GetComponent<>();

D. audio = GetComponent. Audio<Source>;

• Line A

• Line B

• Line C

• Line D

When you run the code below, you get the following error: "NullReferenceException: Object reference not set to an instance of an object." What is most likely the problem?(See live stream for code snippet)

• The Player object does not have a collider

• The Enemy object does not have a Rigidbody component

• The “Start” method should actually be “Update"

• There is no object named “Player” in the scene
