Grid -

A network of horizontal and vertical lines that provide coordinates for locating points on an image

Bug -

An error in a program

Debugging -

Finding and fixing problems in your algorithm or program

Program -

An algorithm that has been coded into something that can be run by a machine

fill ("color"); -

The color of the inside of a shape

ellipse (x,y,w,h); -

An elongated circle, or oval shape

x coordinate -

Tells how far something is from the left side of the display area

rect (x,y); -

Creates a square.

coordinates -

These are used to place shapes on the grid

y coordinate -

Tells how far something is from the top of the display area.

What does \n fill("yellow"); \n rect(350, 0); \n create and where is it located?

Will create a yellow square in the top right hand corner of the grid.

Parameter -

An extra piece of information is passed on to a function to customize it for a specific need.

noStroke() -

Turns off the border of a shape.

Parameters -

Additional information provided as input to a block to customize it's functionality

Which number will make the ellipse taller or shorter? ellipse(3500,300,100,250); or ellipse(3500,300,100,250);

250

randomNumber (min,max) -

Generates different numbers each time the program is run.

Variable -

A placeholder for a piece of information that can change

Labels can include spaces -

False

var circleSize = randomNumber(0,250); -

Part of the code that will change the size of the circle each time the program is run.

Labels cannot begin with a number -

True

If you spell a word wrong, your code will not work. -

True

camelCase -

A convention for naming variables that capitalizes the first letter of every word without spaces

Sprite -

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

Property -

Attributes that describe an object's characteristics such as height and width

sprite.scale -

Controls how large or small the sprite is

drawSprites(); -

Will draw all of the sprites on your screen

What is the name of the sprite in this code? var kite = createSprite(300, 50); -

kite

Which code will make the kite smaller? kite.scale = 0.3; or kite.scale = 0.5; -

kite.scale = 0.3;

This command will create words in your scene. -

text

The order of the code is very important. -

True

drawSprites is usually where in your code? -

At the end.

background -

Fills the screen with color.

textSize -

This command changes the appearance of your text

Animation -

A series of images that create the illusion of motion by being shown rapidly one after the other

Draw loop -

The draw function runs the same code over and over in a loop

Dot notation -

Used to connect the sprite label with the property

arc( x,y,w,h, start,stop) -

Draws an arc onto the display from start to stop with the angle, centered at x and y

shape(x1, y1, x2, y2, ..., xn, yn) -

Connects the points to draw a shape

What does fill("yellow"); rect(350, 350); create and where is it located?

Will create a yellow square in the lower right-hand corner of the grid.
