Head Guess Game

In this guessing game the player holds the Microbit on their head and has 1 minute to guess random things that appear on the Microbit.

1 - Create a new Microbit project.

Go to the makecode.microbit.org website and create a new project.

2 - Start the countdown

In the game the player will have 60 seconds to guess as many things as possible.

Add the following code to start the countdown and give the player 2 lives.

game.setLife(2)
game.startCountdown(60000)

There are 1,000 milliseconds in 1 second, so 60,000 milliseconds equals 60 seconds.

3 - Create a list of random things

We need a list of the random words that will appear on the Microbit screen (by scrolling across).

Create a text list by adding the following code underneath the start countdown block. Add in lots of different random things, animals, people etc.

game.setLife(2)
game.startCountdown(60000)
let text_list = ["Galway", "plane", "xbox", "Ronaldo"]


4 - Show one of the things

To get a new thing from the list, the player will put the Microbit with the logo up. When the Microbit detects this gesture, we will pick a random item from our list and display it.

So if we have 5 items in our list they will be indexed as follows:
0.) apple
1.) moon
2.) plane
3.) xbox
4.) Kerry

The amount of items (or length of our list) is 5, so if we are choosing a random item using the index we will need to choose between 0 and 4 (or between 0 and [5 minus 1]).

Add the following code.

input.onGesture(Gesture.LogoUp, function () {
    basic.showString("" + (text_list[randint(0, text_list.length - 1)]))
})
let text_list: string[] = []


5 - Correct guess

When the item is being displayed on the Microbit the player will ask questions to the other people such as "Is it an animal?" or "Is it a place?".

If he or she guesses it right then they will tilt the Microbit so the screen is pointing down. This will give them a point.

Add the following code to your project.

input.onGesture(Gesture.ScreenDown, function () {
    game.addScore(1)
})
