create a snowflake fall animation #animation#forever #docs
|

|
|
This is the answer key for the [snowflake fall quiz](/microbit/lessons/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)
|
||
|
|
})
|
||
|
|
```
