# rock paper scissors activity A classic game against the micro:bit. ### ~avatar avatar ### @video td/videos/rock-paper-scissors-0 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(` . . . # # # # . # . . . # . . # # . # . . . . # # `) } }) ``` ### ~avatar avatar Excellent, you're ready to continue with the [challenges](/microbit/lessons/rock-paper-scissors/challenges)! ### ~
