Rock, paper, scissors

Home

Pseudocode

1. On Shake a random number will be selected between 0, 1 and 2
2. If it is a 0 then display rock
3. If it is a 1 then display paper
4. If it is a 2 then display scissors
5. If the A button is press, clear the screen for the next match

Step by Step

1. Create a new code project if you haven’t done so already.
2. Lets start by adding on shake block to your code.
3. Next lets create a variable called ‘hand’. This will hold a number 0, 1 or 2, where a 0 is a rock, a 1 is paper, and a 3 is scissors.
4. In our on shake block we need to set the value of hand to our random number (0, 1, or 2) using the pick random math block.
5. Next, we will add an if conditional statment that checks the value of the hand variable.
6. If hand = 0 then we will display a rock using the LEDs.
7. Else If hand = 1 then we will display a paper using the LEDs.
8. Else is not one of the above (i.e. it is 2) then we will display scissors using the LEDs.
9. Add an on button A pressed event, and place the clear screen basic block in it.

When complete your code should look like this:
