Have you ever tried to create a game counter? The concept is fairly simply: increase the game score with on button pressed .

Let's start by adding on button (A) pressed will run each time the user presses A. Let's add a line of code that increments score by 1.

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

Let's add a add points to score block to keep track of the current count. Since the count will change with the add points to score blocks, add a game block score to display the count on screen.

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