|
|
|

|
|
a game similar to "Simon Says" with the BBC micro:bit. #docs
|
||
|
|
|

|
|
## Before we get started
|
||
|
|
|
||
|
|
Complete the following guided tutorial:
|
||
|
|
|
||
|
|
* [tutorial](/microbit/lessons/bop-it/tutorial)
|
||
|
|
|
||
|
|
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
||
|
|
|
||
|
|
```
|
||
|
|
newAction() // ***
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
if (action == 0) {
|
||
|
|
game.addScore(1) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}
|
||
|
|
}) // ***
|
||
|
|
input.onLogoDown(() => {
|
||
|
|
if (action == 1) {
|
||
|
|
game.addScore(1) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}
|
||
|
|
}) // ***
|
||
|
|
input.onGesture(Gesture.Shake, () => {
|
||
|
|
if (action == 2) {
|
||
|
|
game.addScore(1) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}
|
||
|
|
}) // ***
|
||
|
|
input.onButtonPressed("B", () => {
|
||
|
|
basic.showNumber(game.score(), 150) // ***
|
||
|
|
basic.pause(2000) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}) // ***
|
||
|
|
```
|
||
|
|
|
||
|
|
### Challenge 1
|
||
|
|
|
||
|
|
Now let's add some more types of instructions for the player to follow. Let's add `PRESS PIN 0`. Change the global variable `action` to `math->random(4)` so that we can add a new **IF** statement that checks if `action=3`. If it does, display instructions to press pin 0.
|
||
|
|
|
||
|
|
```
|
||
|
|
/**
|
||
|
|
* {highlight}
|
||
|
|
*/
|
||
|
|
export function newAction_() {
|
||
|
|
action = Math.random(4) // ***
|
||
|
|
if (action == 0) {
|
||
|
|
basic.showString("PUSH A", 150) // ***
|
||
|
|
}
|
||
|
|
if (action == 1) {
|
||
|
|
basic.showString("LOGO DOWN", 150) // ***
|
||
|
|
}
|
||
|
|
if (action == 2) {
|
||
|
|
basic.showString("SHAKE", 150) // ***
|
||
|
|
}
|
||
|
|
if (action == 3) {
|
||
|
|
basic.showString("PRESS PIN 0", 150) // ***
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Challenge 2
|
||
|
|
|
||
|
|
Now let's implement `PRESS PIN 0` in the main. Create a condition of `input->on pin pressed("P0")` that will add one to the score and calls the method `new action`.
|
||
|
|
|
||
|
|
```
|
||
|
|
// **. . .**
|
||
|
|
input.onButtonPressed("B", () => {
|
||
|
|
basic.showNumber(game.score(), 150) // ***
|
||
|
|
basic.pause(2000) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}) // ***
|
||
|
|
input.onPinPressed("P0", () => {
|
||
|
|
if (action == 3) {
|
||
|
|
game.addScore(1) // ***
|
||
|
|
newAction() // ***
|
||
|
|
}
|
||
|
|
}) // ***
|
||
|
|
```
|
||
|
|
|
||
|
|
### Challenge 3
|
||
|
|
|
||
|
|
Add `POINT ME NORTH` to the list of possible commands.
