Shapes
This is the full line of code that you would use to draw a line from the top left corner to the bottom right corner of a 500x500 canvas.
What is line(0, 0, 500, 500);
These are the special variables that represent the position of the user's mouse on the X and Y axes of the canvas.
What are mouseX and mouseY ?
This function, used to set the size of the canvas and initial background color, is only called once at the start when running a program in Processing.
What is void setup() ?
This is the range of values that you can use when specifying colors in Processing.
What is 0-255 ?
This is the rectMode you would use if you wanted to draw a rectangle by providing the top left corner, width, and height.
What is CORNER ?
This the keyword that extends an if statement, specifying a block of code to execute when the expression in the if statement was false.
What is else ?
This is the full line of code we would use to declare a new variable called "n" for holding integer values, and set it equal to 100.
What is int n = 100;
This is the full name of the function that is called continuously to update the display in a Processing program.
What is void draw() ?
This the full line of code that you would use to draw a circle centered at (100, 200) with radius 150.
What is circle(100, 200, 300);
OR
What is ellipse(100, 200, 300, 300);
This is the full name of the function that is called every time the user types a key.
What is void keyPressed() ?
This is the data type we would use for a variable that could hold a decimal value.
What is float?
This is the full line of code you would use to set the color used to fill in shapes to pure blue.
What is fill(0, 0, 255);
This is the full line of code that you would use to draw a point at the exact middle of the canvas, even if you don't know the canvas size.
What is point(width/2, height/2);
This is the logical operator used to combine multiple conditions in an if statement so that the code only runs if ALL conditions are true.
What is && ?
This is the popular programming language that Processing is based on, and shares many characteristics with.
What is Java?
This is how you would generate a random number between greater than or equal to 1, and less than 10.
This is the full line of code that you would use to draw an ellipse centered at the user's mouse, with a random height and width not exceeding the canvas size.
What is ellipse(mouseX, mouseY, width, height);
This is the operator that is used to check if AT LEAST one of multiple conditions is true, rather than requiring all of them to be true.
What is || ?
This is how we would change the frame rate of Processing so that the frame only updates once every 200 milliseconds (or 0.2 seconds).
This is the binary (base 2) representation of the decimal (base 10) number 29.
What is 11101?
