Coding challenges for the magic 8 tutorial
|
|
|
|
## Before we get started
|
|
|
|
Complete the following [guided tutorial](/lessons/magic-8/activity), and your code should look like this:
|
|
|
|
```blocks
|
|
basic.showString("ASK A QUESTION")
|
|
basic.showNumber(8)
|
|
input.onGesture(Gesture.Shake, () => {
|
|
basic.clearScreen()
|
|
let randomNumber = Math.randomRange(0, 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.
|
|
|
|
```blocks
|
|
basic.showString("ASK A QUESTION")
|
|
basic.showNumber(8)
|
|
input.onGesture(Gesture.Shake, () => {
|
|
basic.clearScreen()
|
|
let randomNumber = Math.randomRange(0, 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.
|
|
|
|
|
|
```blocks
|
|
basic.showString("ASK A QUESTION")
|
|
basic.showNumber(8)
|
|
input.onGesture(Gesture.Shake, () => {
|
|
basic.clearScreen()
|
|
let randomNumber = Math.randomRange(0, 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!".
|
|
|
|
```blocks
|
|
basic.showString("ASK A QUESTION")
|
|
basic.showNumber(8)
|
|
input.onGesture(Gesture.Shake, () => {
|
|
basic.clearScreen()
|
|
let randomNumber = Math.randomRange(0, 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!
