On Button Pressed
Start an event handler (part of the program that will run when something happens, like when a button is pressed).
This handler works when button A or B is pressed, or A and B together.
When you are using this function in a web browser, click the buttons on the screen instead of the ones
on the @boardname@.
- For button
AorB: This handler works when the button is pushed down and released within 1 second. - For
AandBtogether: This handler works whenAandBare both pushed down, then one of them is released within 1.5 seconds of pushing down the second button.
input.onButtonEvent(Button.A, ButtonEvent.Click, () => {})
Find out how buttons provide input to the @boardname@ in this video:

Example: count button clicks
This example counts how many times you press the A button.
Each time you press the button, the LED screen shows the count variable getting bigger.
let count = 0
basic.showNumber(count)
input.onButtonEvent(Button.A, ButtonEvent.Click, () => {
count++;
basic.showNumber(count);
})
Example: roll dice
This example shows a number from 1 to 6 when you press the B button.
input.onButtonEvent(Button.B, ButtonEvent.Click, () => {
let dice = randint(0, 5) + 1
basic.showNumber(dice)
})
~hint
This program adds a 1 to random(5) so the numbers on the dice will come out right.
Otherwise, sometimes they would show a 0.
