TASK

Last week you made a simple dice program using 3 bricks of code

Can you modify this program to use a variable instead so that this value is then stored?

The Dice Tutorial

Solution

TASK

Ok - challenge time now....

Create the classic Rock, Paper, Scissors game on the microbit.

Teacher Note - For higher sets start with this without support. The next slides drip release help.  The last is a link to scaffolded walkthrough.

Hint 1

You have 3 possible outcomes

It would be handy to have a variable assigned a random number between 1 and 3 to help with this

Hint 2

We need to use a logic brick to know what to do when the variable is a 1, 2 or a 3

We could then display the right image in each case

We need another brick here to check if the variable "value" is a 1 or a 2.  Look in Logic section for this

Hints support

You will need a variable to store a random number

IF that number is a 1 (for example) you display a Rock image

ELSE IF that number is a 2, you display a Paper image

ELSE you display a scissors image.

Condition?

You need to put some code in here that checks if your variable is equal to a certain number
