What does the following code do in the game lab?

False

a single image within an animation

Frame

Frame Rate

The following sprite.scale = 0.5 does the following to the sprite charachter

Makes the sprite one half the original size

The following code does what in game lab function draw () {}

The lines of code contained inside its block are continuously executed until the program is stopped.

The most important thing when you choose how to label your variables is to use a consistent style so it's easy for you to remember the exact spelling and capitalization of your variables

True

You can add text in game lab.

True

In which corner of the screen will the circle be drawn with the following code? car xPosition = 300 var whatstheY = 100

Upper right

Names used in coding that refer to stored data in your apps

Variables

Using a series of pictures to create the illusion of smooth movement from frame to frame is called

an animation

Where does the draw function need to be placed in the following code so that the shalt shaker will loop? var salt = createSprite(200,200); salt.setAnimation("salt"); background ("skyblued"); salt.y randomNumber(200,220); draw sprites();

before background("skyblue")

The setAnimation (); code does the following

call the sprite name located in between the () to be drawn on the screen from the animation Tab in Game Lab

counter pattern

What does the following code do? var sprite = createSprite ();

creates a new sprite and assigns it to a variable

Attributes that describe and object's characteristics

property

A graphic character on the screen with properties that describe its location, movement, and look.

sprite

What is a "watcher" used for in coding?

to use as a debugging tool that watches your variables while the program runs.
