# Dice
|
||
|
|
||
|
## Introduction
|
||
|
|
||
|

|
||
|
|
||
|
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@.
|
||
|
|
||
|
```blocks
|
||
|
input.onGesture(Gesture.Shake, () => {
|
||
|
|
||
|
})
|
||
|
```
|
||
|
|
||
|
## Step 2 @fullscreen
|
||
|
|
||
|
Place the ``||basic:show number||`` block in the ``||input:on shake||`` block to display a number.
|
||
|
|
||
|
```blocks
|
||
|
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.
|
||
|
|
||
|
```blocks
|
||
|
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!
|
||
|
|
||
|
```blocks
|
||
|
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@!
