Name

mouseMoved()

Examples
// Move the mouse across the image
// to change its value

int value = 0;

void draw() {
  fill(value);
  rect(25, 25, 50, 50);
}

void mouseMoved() {
  value = value + 5;
  if (value > 255) {
    value = 0;
  }
}
Description The mouseMoved() function is called every time the mouse moves and a mouse button is not pressed.

Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.
