create a snowflake fall animation.

This is the answer key for the snowflake fall quiz.

1. In reference to an animation, what is an "interval"?

The number of milliseconds to pause after each image frame.

2. What is the interval of the animation?

basic.showAnimation(`
. . . . .
. . # . .
. # # # .
. . # . .
. . . . .
`, 400)

3. Write the code to allow this animation to never stop displaying on the BBC micro:bit

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

4. Write the code to create a forever loop that shows an animation of these images. Change the interval from 400 to 800 to make the animation go twice as slow!

basic.forever(() => {
    basic.showAnimation(`
. . . . . # # # # #
. . # . . # # . # #
. # # # . # . # . #
. . # . . # # . # #
. . . . . # # # # #
`, 800)
})
