In the last example, everything was a bit static. The draw-function got called over and over again (30-60 times per second), but it only draw the same rectangle each time. Let’s create some movement by changing where the rectange is drawn each frame.
random(min, max); returns a random decimal number between min and max. The example below uses random to generate values for the x and y coordinate of a rectangle. Try out the example and create different shapes with random position and size.
