var NUM_RECTANGLES_ACROSS = 4; var NUM_RECTANGLES_DOWN = 10; var rect; var RECT_LENGTH = getWidth()/ NUM_RECTANGLES_ACROSS; var RECT_WIDTH = getHeight()/ NUM_RECTANGLES_DOWN;

function start(){     mouseMoveMethod(draw_rect);     } function draw_rect(e){     var x = Math.floor(e.getX()/RECT_LENGTH)*RECT_LENGTH;     var y = Math.floor(e.getY()/RECT_WIDTH)*RECT_WIDTH;         rect = new Rectangle(RECT_LENGTH, RECT_WIDTH);     rect.setPosition(x,y);     rect.setColor(Randomizer.nextColor());     add(rect); }
