Coding challenges for the rock paper scissors tutorial. #docs

|
|
## Before we get started
|
||
|
|
|
||
|
|
Complete the following [guided activity](/microbit/lessons/rock-paper-scissors/activity) , your code should look like this:
|
||
|
|
|
||
|
|
```
|
||
|
|
input.onGesture(Gesture.Shake, () => {
|
||
|
|
let img = images.createImage(`
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. # # # . # . . . # . . # . .
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
`)
|
||
|
|
img.plotFrame(Math.random(3))
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
### Challenge 1
|
||
|
|
|
||
|
|
When the `A` button is pressed, increment the **score** by ``1``. You can use the `game->add score` function for that.
|
||
|
|
|
||
|
|
```
|
||
|
|
input.onGesture(Gesture.Shake, () => {
|
||
|
|
let img1 = images.createImage(`
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. # # # . # . . . # . . # . .
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
`)
|
||
|
|
img1.plotFrame(Math.random(3))
|
||
|
|
})
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
game.addScore(1) // ***
|
||
|
|
}) // ***
|
||
|
|
```
|
||
|
|
|
||
|
|
### Challenge 2
|
||
|
|
|
||
|
|
After incrementing the score, display the total number of wins you have.
|
||
|
|
|
||
|
|
```
|
||
|
|
input.onGesture(Gesture.Shake, () => {
|
||
|
|
let img2 = images.createImage(`
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. # # # . # . . . # . . # . .
|
||
|
|
. # # # . # . . . # # # . # .
|
||
|
|
. . . . . # # # # # . . . . #
|
||
|
|
`)
|
||
|
|
img2.plotFrame(Math.random(3))
|
||
|
|
})
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
game.addScore(1)
|
||
|
|
basic.showString("WINS: ", 150) // ***
|
||
|
|
basic.showNumber(game.score(), 150) // ***
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
* Run and compile the code to see if it works as expected.
|
||
|
|
|
||
|
|
### Challenge 3
|
||
|
|
|
||
|
|
You have successfully tracked and displayed the number of wins on the BBC micro:bit! However, what about losses? Use `game->remove life` when button `B` is pressed.

||
|
|

|
* Run and compile the code to see if it works as expected.
