Welcome! This tutorial will teach how design a snowfall animation. Let's get started!

~

Let's start by creating a basic->forever loop that will allow us to repeat the animation code. Any code in the forever loop will repeat in the background... forever.

basic.forever(() => {
}) // ***

The next step is to add basic->show animation inside the forever loop to repeat an animation.

basic.forever(() => {
    basic.showAnimation(`
. . . . . . . . . .
. . # . . . . . . .
. # # # . . . . . .
. . # . . . . . . .
. . . . . . . . . .
`, 400) // ***
})

Run your code in the simulator or download it to your BBC micro:bit to see what happens!
