Dice

Introduction @unplugged

A microbit dice

Let's turn the @boardname@ into a dice! To do so, we need 3 pieces of code: detect a throw (shake), pick a random number, show the number.

Step 1 @fullscreen

Place the ||input:on shake|| block. It runs code when you shake the @boardname@.

input.onGesture(Gesture.Shake, () => {

})

Step 2 @fullscreen

Place the ||basic:show number|| block in the ||input:on shake|| block to display a number.

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(0)
})

Step 3 @fullscreen

Place the ||Math:pick random|| block in an ||input:on shake|| block to pick a random number.

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(Math.randomRange(0, 10))
})

Step 4 @fullscreen

A typical dice shows values from 1 to 6. So, in ||Math:pick random||, don't forget to choose the right minimum and maximum values!

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(Math.randomRange(1, 6))
})

Step 5

Use the simulator to try out your code. Does it show the number you expected?

Step 6

If you have a @boardname@ connected, click |Download| and transfer your code to the @boardname@!
