Welcome! This tutorial will teach how to program a game of truth or dare on the @boardname@. Let's get started!

~

Begin by using Show LEDs to create an "up-arrow" image, which will point to someone.

basic.showLeds(`
    . . # . .
    . # # # .
    # # # # #
    . . # . .
    . . # . .
    `)

Now let's create a condition to know when button A is pressed so that we can display "truth" or "dare" on the @boardname@. We want the @boardname@ to randomly choose whether to display "truth" or display "dare". We can use accomplish this by using pick random (1).

basic.showLeds(`
    . . # . .
    . # # # .
    # # # # #
    . . # . .
    . . # . .
    `)
input.onButtonPressed(Button.A, () => {
    let random = Math.random(2)
})

Now let's display the appropriate message for each scenario of random.

basic.showLeds(`
    . . # . .
    . # # # .
    # # # # #
    . . # . .
    . . # . .
    `)
input.onButtonPressed(Button.A, () => {
    let random = Math.random(2)
    if (random == 0) {
        basic.showString("TRUTH")
    } else {
        basic.showString("DARE")
    }
})

Notice how the arrow didn't display again after pressing button A. Let's add a line of code that displays the arrow again.

basic.showLeds(`
    . . # . .
    . # # # .
    # # # # #
    . . # . .
    . . # . .
    `)
input.onButtonPressed(Button.A, () => {
    let random = Math.random(2)
    if (random == 0) {
        basic.showString("TRUTH")
    } else {
        basic.showString("DARE")
    }
    basic.showLeds(`
    . . # . .
    . # # # .
    # # # # #
    . . # . .
    . . # . .
    `)
})

  • Run your program: Press button A!
