### Challenge 0
|
|
|
|
Welcome! This [guided tutorial](/hzckbb) will help you create the script to clear the screen!
|
|
|
|
Your goal is to clear the screen after displaying an animation. Begin by showing and displaying an animation. Remember that the `show animation` is in the `basic` namespace. We then need to detect when the "A" button is pressed. Finally, clear the screen by typing in `basic->clear screen`.
|
|
|
|
Your main function should look like this:
|
|
|
|
```
|
|
basic.showAnimation(`
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
. . . . . # # # # # # # # # # . . . . .
|
|
. . . . . # # # # # # # # # # # # # # #
|
|
. . . . . . . . . . . . . . . # # # # #
|
|
`, 400)
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.clearScreen()
|
|
})
|
|
```
|
|
|
|
* tap the `run` button to view the script on the monitor.
|
|
|
|
### Challenge 1
|
|
|
|
Create an event handler for Button "B".
|
|
|
|
```
|
|
basic.showAnimation(`
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
. . . . . # # # # # # # # # # . . . . .
|
|
. . . . . # # # # # # # # # # # # # # #
|
|
. . . . . . . . . . . . . . . # # # # #
|
|
`, 400)
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.clearScreen()
|
|
})
|
|
input.onButtonPressed(Button.B, () => {
|
|
})
|
|
```
|
|
|
|
### Challenge 2
|
|
|
|
Replay the animation when the "B" button is pressed by typing in `basic->show animation(..., 400)`.
|
|
|
|
```
|
|
basic.showAnimation(`
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
. . . . . # # # # # # # # # # . . . . .
|
|
. . . . . # # # # # # # # # # # # # # #
|
|
. . . . . . . . . . . . . . . # # # # #
|
|
`, 400)
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.clearScreen()
|
|
})
|
|
input.onButtonPressed(Button.B, () => {
|
|
basic.showAnimation(`
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
# # # # # # # # # # . . . . . . . . . .
|
|
. . . . . # # # # # # # # # # . . . . .
|
|
. . . . . # # # # # # # # # # # # # # #
|
|
. . . . . . . . . . . . . . . # # # # #
|
|
`, 400) // ***

})
|
|
```
|
|
|
|
### Challenge 3
