Welcome! This tutorial will help you create a game of rock paper scissors with the micro:bit. Let's get started!
|
||
|
||
### ~
|
||
|
||
To create a new script, go to the [Create Code](/microbit/create-code) page and tap *New Project* under **Touch Develop**.
|
||
|
||
We want the micro:bit to choose rock, paper, or scissors when it is shaken. Let's begin by creating an on shake condition so the micro:bit will run code when it is shaken.
|
||
|
||
|
||
```blocks
|
||
|
||
input.onGesture(Gesture.Shake, () => {
|
||
|
||
})
|
||
|
||
```
|
||
|
||
Next, create a variable and store pick random number from 0 to 2. On shake, a number will be randomly picked from 0-2. We will randomly display an image based on the random number returned.
|
||
|
||
|
||
```blocks
|
||
input.onGesture(Gesture.Shake, () => {
|
||
let img = Math.random(3)
|
||
})
|
||
|
||
```
|
||
|
||
The micro:bit will look like it's showing 1 frame of the image by displaying the whole image when pick random is equal to 2. We can help the micro:bit randomly decide which image to use by pick random. The micro:bit will randomly pick the image to display with show LEDs and the pick random function.
|
||
|
||
```blocks
|
||
input.onGesture(Gesture.Shake, () => {
|
||
let img = Math.random(3)
|
||
if (img == 2) {
|
||
basic.showLeds(`
|
||
# # # # #
|
||
# . . . #
|
||
# . . . #
|
||
# . . . #
|
||
# # # # #
|
||
`)
|
||
|
||
}
|
||
})
|
||
|
||
|
||
```
|
||
|
||
The micro:bit will look like it's showing 1 frame of the image by displaying the whole image when pick random is equal to 1. We can help the micro:bit randomly decide which image to use by pick random. The micro:bit will randomly pick the image to display with show LEDs and the pick random function.
|
||
|
||
```blocks
|
||
input.onGesture(Gesture.Shake, () => {
|
||
let img = Math.random(3)
|
||
if (img == 2) {
|
||
basic.showLeds(`
|
||
# # # # #
|
||
# . . . #
|
||
# . . . #
|
||
# . . . #
|
||
# # # # #
|
||
`)
|
||
|
||
} else if (img == 1) {
|
||
basic.showLeds(`
|
||
. . . . .
|
||
. # # # .
|
||
. # # # .
|
||
. # # # .
|
||
. . . . .
|
||
`)
|
||
}
|
||
})
|
||
```
|
||
|
||
The micro:bit will look like it's showing 1 frame of the image by displaying the whole image when pick random is not equal to 2 and not equal to 1. We can help the micro:bit randomly decide which image to use by pick random. The micro:bit will randomly pick the image to display with show LEDs and the pick random function.
|
||
|
||
|
||
```blocks
|
||
input.onGesture(Gesture.Shake, () => {
|
||
let img = Math.random(3)
|
||
if (img == 2) {
|
||
basic.showLeds(`
|
||
# # # # #
|
||
# . . . #
|
||
# . . . #
|
||
# . . . #
|
||
# # # # #
|
||
`)
|
||
|
||
} else if (img == 1) {
|
||
basic.showLeds(`
|
||
. . . . .
|
||
. # # # .
|
||
. # # # .
|
||
. # # # .
|
||
. . . . .
|
||
`)
|
||
} else {
|
||
basic.showLeds(`
|
||
. . . # #
|
||
# # . # .
|
||
. . # . .
|
||
# # . # .
|
||
. . . # #
|
||
`)
|
||
}
|
||
})
|
||
|
||
```
