What am I doing wrong? int circleX = 50; int circleY = 50; int circleSize = 50; int circleFill = 0; int speed = 1; // basic setup void setup() { size(200,200); background(255); smooth(); } void draw() { stroke(0); fill(0); // circle top left ellipse(circleX,circleY,circleSize,circleSize); // circle top right ellipse(150,50,50,50); // circle bottom left ellipse(50,150,50,50); // circle bottom right ellipse(150,150,50,50); } void move() { circleX = circleX + speed; if (circleX > width) { circleX = 10; } } void display() { fill(circleFill); ellipse(circleX,circleY,circleSize,circleSize); } also do you know how I would create the > symbol on a mac because at the moment I can only copy and paste it. I've tried alt + every key available but still no joy Thank you Hi I’ve attempted adding variable to A) with the intention of making it track from left to right but nothing is happening.

int circleX = 50;
int circleY = 50;
int circleSize = 50;
int circleFill = 0;
int speed = 1;

// basic setup
void setup() {
size(200,200);
background(255);
smooth();
}

void draw() {
stroke(0);
fill(0);
// circle top left
ellipse(circleX,circleY,circleSize,circleSize);
// circle top right
ellipse(150,50,50,50);
// circle bottom left
ellipse(50,150,50,50);
// circle bottom right
ellipse(150,150,50,50);
}

void move() {
circleX = circleX + speed;
if (circleX > width) {
circleX = 10;
}
}

void display() {
fill(circleFill);
ellipse(circleX,circleY,circleSize,circleSize);
}

also do you know how I would create the > symbol on a mac because at the moment I can only copy and paste it. I’ve tried alt + every key available but still no joy

Thank you
