The code below has a mistake. Which option correctly identifies it?
function setup() { createCanvas(400, 400); background(220); showAverage(0, 0);}
function showAverage(total, count) { var average = total / count; text(average, width/2, height/2);}
Given the following code, what is the value of currentValue when frameCounter is equal to 10? Hint: The % operator, called the modulo operator, returns the remainder of the division of two numbers.
let frameCounter = 0;let currentValue;
function draw() { background(255, 255, 255); frameCounter = frameCounter + 1; if (frameCounter % 6 < 3) { currentValue = 150; } else { currentValue = 250; }}
In a Flappy Bird game, the bird’s vertical position is tracked by birdY, and isFlapping is a variable that prevents the bird from flapping again while it is still rising. Given the following code snippet, what happens when the spacebar is pressed while the bird is falling?
if (birdY > 300) { isFlapping = false;}
if (keyIsPressed && key == " " && !isFlapping) { velocityY = -12; isFlapping = true; flap.play();}
Given the following code, which letter should be pressed to move the circle to the left, and how many times should it be pressed to place the circle at the centre of the canvas?
let x = 400;
function setup() { createCanvas(400, 400);}
function draw() { background(0, 255, 255); fill(255, 0, 0); ellipse(x, 200, 50, 50);}
function keyPressed() { if (key == "l") { x = x + 20; } else if (key == "j") { x = x - 20; }}
Given the following code, which statement should be added to draw() so that the square keeps re-entering from the left side once it leaves the canvas on the right?
let squareX = 0;
function setup() { createCanvas(400, 300);}
function draw() { background(200, 200, 200); rect(squareX, 150, 20, 20); squareX = squareX + 2;}
Given the following code, what is displayed on the canvas?
function setup() { createCanvas(400, 400);}
function draw() { background(220); stroke(0, 0, 255); fill(255, 255, 0); rect(mouseX, mouseY, 40, 40);}
Given the following code, a student holds the mouse down for a few seconds, then releases it. What do they observe?
function setup() { createCanvas(500, 500); background(220, 220, 220);}
function draw() { if (mouseIsPressed) { fill(255, 0, 0); } else { fill(0, 0, 255); } ellipse(250, 250, 80, 80);}
Given the following code, what do you observe on the canvas?
let circleX = 30;
function setup() { createCanvas(400, 400); background(200, 200, 200);}
function draw() { ellipse(circleX, 200, 20, 20); circleX = circleX + 2;}
