die roll activity
Create a die on the BBC micro:bit
Let's create a condition for when the BBC micro:bit is shaken.
input.onGesture(Gesture.Shake, () => {
})
We need to show a random value from 1 to 6 on our die. So let's make a local variable called roll.
input.onGesture(Gesture.Shake, () => {
let roll = Math.random(6)
})
We need a condition for if roll is 5. We will show a 6
if roll is 5 because roll has a range from 0 to 5. We can use Show LEDs
to display the side of a die that shows 6.
input.onGesture(Gesture.Shake, () => {
let roll1 = Math.random(6)
if (roll1 == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .
`, 400)
}
})
Let's use an else if
condition for if roll is 4. If roll is 4 we can show 5 dots on the die.
input.onGesture(Gesture.Shake, () => {
let roll2 = Math.random(6)
if (roll2 == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .
`, 400)
} else if (roll2 == 4) {
basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .
`, 400)
}
})
Now we need to repeat the same steps for if roll is 3. If roll is 3 we will show 4
on the die. Let's also repeat these steps to show the 3, 2, and 1 on the die. We are almost done with our die!
input.onGesture(Gesture.Shake, () => {
let roll3 = Math.random(6)
if (roll3 == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .
`, 400)
} else if (roll3 == 4) {
basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .
`, 400)
}
else if (roll3 == 3) {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # . # .
. . . . .
`, 400)
}
else if (roll3 == 2) {
basic.showLeds(`
# . . . .
. . . . .
. . # . .
. . . . .
. . . . #
`, 400)
}
else if (roll3 == 1) {
basic.showLeds(`
. . . . .
. # . . .
. . . . .
. . . # .
. . . . .
`, 400)
}
else {
basic.showLeds(`
. . . . .
. . . . .
. . # . .
. . . . .
. . . . .
`, 400)
}
})
