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. (If a button is being pressed, mouseDragged() is called instead.) 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.
Syntax |
    mouseMoved()
    mouseMoved(event)
Returns | void
