I am in a class which is teaching Programming, and my professor and I are both stumped. I am trying to set a mousePressed function so that when the mouse is pressed the cursor turns into an image which I have loaded. Here is the code as written. You will have to include your own images if you want to try this. Thanks!

PImage b;
PImage b2;

void setup() {
background(10);
 size(700,600);
b = loadImage("071108-cvr-bernanke-grid1col-8a.hmedium.jpg");
 b2 = loadImage("OOPS.gif");
image(b, 123, 150);
}

void draw() {
if(mousePressed){
  cursor(b2, mouseX, mouseY);
} else {
  noCursor();
}
}
