counter activity
Display a number with a variable.
Let’s start by creating a local variable count
to keep track of the current count.
let count = 0
The code under on button pressed("A")
will run each time the user presses A. Let’s add a line of code that increments count
by 1
.
let count = 0
input.onButtonPressed(Button.A, () => {
count = count + 1
})
Since the count has changed, it’s time to refresh the screen display. Let’s add a line of code to display the count on screen.
let count = 0
input.onButtonPressed(Button.A, () => {
count = count + 1
basic.showNumber(count)
})
