Coding challenges for the bounce image tutorial. #docs
|
|
|
|
## Before we get started
|
|
|
|
Complete the following guided tutorial:
|
|
|
|
* [tutorial](/lessons/bounce-image/tutorial)
|
|
|
|
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
|
|
|
```
|
|
basic.forever(() => {
|
|
basic.showAnimation(`
|
|
# . . . . . # . . . . . # . . . . . # . . . . . #
|
|
# . . . . . # . . . . . # . . . . . # . . . . . #
|
|
# . . . . . # . . . . . # . . . . . # . . . . . #
|
|
# . . . . . # . . . . . # . . . . . # . . . . . #
|
|
# . . . . . # . . . . . # . . . . . # . . . . . #
|
|
`, 200)
|
|
})
|
|
```
|
|
|
|
### Challenge 1
|
|
|
|
Now, let's add frames to reverse the animation so it looks like the bar is bouncing off the right edge of the display.
|
|
|
|
```
|
|
basic.forever(() => {
|
|
basic.showAnimation(`
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
`, 200) // ***
|
|
})
|
|
```
|
|
|
|
* Run the code to see if it works as expected.
|
|
|
|
### Challenge 2
|
|
|
|
Let's add a condition for on shake!
|
|
|
|
```
|
|
basic.forever(() => {
|
|
basic.showAnimation(`
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
`, 200)
|
|
})
|
|
input.onGesture(Gesture.Shake, () => {
|
|
}) // ***
|
|
```
|
|
|
|
### Challenge 3
|
|
|
|
When the BBC micro:bit is shaken we want to show a new animation. Here is an example, but you can create your own. Be creative!
|
|
|
|
```
|
|
basic.forever(() => {
|
|
basic.showAnimation(`
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
# . . . . . # . . . . . # . . . . . # . . . . . # . . . # . . . # . . . # . . . # . . . .
|
|
`, 200)
|
|
})
|
|
input.onGesture(Gesture.Shake, () => {
|
|
basic.showAnimation(`
|
|
. . . . . . . . . . # # # # # . . . . . . . . . .
|
|
. . . . . . # # # . # # # # # . # # # . . . . . .
|
|
. . # . . . # # # . # # # # # . # # # . . . # . .
|
|
. . . . . . # # # . # # # # # . # # # . . . . . .
|
|
. . . . . . . . . . # # # # # . . . . . . . . . .
|
|
`, 200) // ***
|
|
})
|
|
```
|
|
|
|
* Run the code to see if it works as expected.
