magic 8 challenges

Coding challenges for the magic 8 tutorial

Before we get started

Complete the following guided tutorial, and your code should look like this:

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () =>  {
    basic.clearScreen()
    let randomNumber = Math.random(2)
    if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    } else {
        basic.showString("I DON'T KNOW")

    }
    basic.showNumber(8)

})

Challenge 1

Now let's increase the number of responses the magic 8 ball can give. How about 5 responses instead? Let's change the limit of pick random to 4.

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () =>  {
    basic.clearScreen()
    let randomNumber = Math.random(4)
    if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    } else {
        basic.showString("I DON'T KNOW")

    }
    basic.showNumber(8)

})

Challenge 2

Now have the magic 8 ball respond "Try again" if randomNumber is 3.

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber = Math.random(4)
    if (randomNumber == 3) {
        basic.showString("TRY AGAIN")
    } else if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    } else {
        basic.showString("I DON'T KNOW")
    }
    basic.showNumber(8)
})

Challenge 3

Now what about if randomNumber is 4? Let's have the magic 8 ball respond "Definitely!".

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber = Math.random(4)
    if (randomNumber == 4) {
        basic.showString("DEFINATELY")
    } else if (randomNumber == 3) {
        basic.showString("TRY AGAIN")
    } else if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    }
    else {
        basic.showString("I DON'T KNOW")
    }
    basic.showNumber(8)
})

Challenge 4

Add 3 more responses so your magic 8 ball has 8 possible responses. Be creative!
