game counter challenges

Coding challenges for the game counter.

Before we get started

Complete the following activity . Your code should look like this:

input.onButtonPressed(Button.A, () => {
    game.addScore(1);
    basic.showNumber(game.score())
});

Challenge 1

Let's add the code to score when B is pressed. Add an event handler with on button (B) pressed then add the code to score.

input.onButtonPressed(Button.A, () => {
    game.addScore(1);
    basic.showNumber(game.score())
});

input.onButtonPressed(Button.B, () => {
    game.addScore(-1);
    basic.showNumber(game.score())
});

Challenge 3

Now let's try to reset the counter when the micro:bit is shaken. You will need to register an event handler with on shake.
