```blocks
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
```
## 2. Write the code that will display the string, "PUSH A" if the global variable called 'action' is equal to 0
2016-05-09 19:32:02 +02:00
```blocks
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 0) {
basic.showString("PUSH A", 150)
}
```
## 3. Write the code that increments the score if button A is pressed when the global variable called 'action' is equal to 1
2016-05-09 19:32:02 +02:00
```blocks
input.onButtonPressed(Button.A, () => {
2016-05-09 19:32:02 +02:00
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 0) {
game.addScore(1)
}
})
```

```blocks
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 1) {
basic.showString("LOGO DOWN", 150)
}
```
## 5. Write the code that increments the score if the BBC micro:bit logo is tilted down when the global variable called 'action' is equal to 1
2016-05-09 19:32:02 +02:00
```blocks
2016-03-26 00:47:20 +01:00
input.onLogoDown(() => {
2016-05-09 19:32:02 +02:00
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 1) {
game.addScore(1)
}
})
```
## 6. Write the code that will display the string "SHAKE" if the global variable called 'action' is equal to 2
2016-05-09 19:32:02 +02:00
```blocks
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 2) {
basic.showString("SHAKE", 150)
}
```
## 7. Write the code that increments the score if the BBC micro:bit is shaken when the global variable called 'action' is equal to 2
2016-05-09 19:32:02 +02:00
```blocks
2016-03-26 00:47:20 +01:00
input.onLogoDown(() => {
2016-05-09 19:32:02 +02:00
let action = Math.random(3)
2016-03-26 00:47:20 +01:00
if (action == 1) {
game.addScore(1)
}
})
```
