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