# Microbit Bop It Game

In this project we will turn our Microbit into a Bop It game using the different inputs in the Microbit. The Microbit will show a random image and you must perform the correct action for that image.

You have 20 seconds to see how many you can get right!

### 1 - Create a new Microbit project

Open the makecode.com website and create a new Microbit project.

### 2 - Create a variable called ‘action’

Create a variable called ‘action’, we will use this variable to store and remember a random action. In the on start block, set ‘action’ to -1 by adding this code:

```let action = -1
```

### 3 - Add a start countdown block

Add a start countdown block and set it to 20000 milliseconds (which is 20 seconds).

```let action = -1
game.startCountdown(20000)
```

This means the player has 20 seconds to get as many correct actions as they can!

### 4 - Set 'action' to a random number

In the forever block we want to check if ‘action’ is equal to -1, if it is then we want to set ‘action’ to a random number between 0 and 2.

```basic.forever(function () {
if (action == -1) {
action = Math.randomRange(0, 2)
}
})
```

We choose a random number between 0 and 2 as that will give us three possibilities: 0, 1 and 2.

### 5 - Display the image

Next depending on what ‘action’ is now equal to, we are going to display an image on our Microbits telling the user what action they need to do.

• action = 0 means you should press the A button (arrow left)
• action = 1 means you should press the B button (arrow right)
• action = 2 means you should press the A+B buttons (arrows left and right)

Add the following code to check what 'action' is equal to and show the appropriate image.

```basic.forever(function () {
if (action == -1) {
action = Math.randomRange(0, 2)
}
if (action == 0) {
basic.showLeds(`
. . # . .
. # . . .
# . . . .
. # . . .
. . # . .
`)
} else if (action == 1) {
basic.showLeds(`
. . # . .
. . . # .
. . . . #
. . . # .
. . # . .
`)
} else if (action == 2) {
basic.showLeds(`
. . # . .
. # . # .
# . . . #
. # . # .
. . # . .
`)
}
})

```
