bop it challenges

a game similar to "Simon Says" with the @boardname@.

Before we get started

Complete the following guided tutorial. Your code should look like this:

let action  = 0;
function newAction() {}
input.onButtonPressed(Button.A, () => {
    if (action == 0) {
        game.addScore(1);
        newAction();
    }
})
input.onLogoDown(() => {
    if (action == 1) {
        game.addScore(1);
        newAction();
    }
}) 
input.onGesture(Gesture.Shake, () => {
    if (action == 2) {
        game.addScore(1);
        newAction();
    }
}) 
input.onButtonPressed(Button.B, () => {
    basic.showNumber(game.score(), 150);
    basic.pause(2000);
    newAction();
}) 

Challenge 1

Now let's add some more types of instructions for the player to follow. Let's add PRESS PIN 0. Change the global variable action to math->random(4) so that we can add a new IF statement that checks if action=3. If it does, display instructions to press pin 0.

let action  = 0;
export function newAction() {
    action = Math.random(4)
    if (action == 0) {
        basic.showString("PUSH A", 150) // ***
    }
    if (action == 1) {
        basic.showString("LOGO DOWN", 150) // ***
    }
    if (action == 2) {
        basic.showString("SHAKE", 150) // ***
    }
    if (action == 3) {
        basic.showString("PRESS PIN 0", 150) // ***
    }
}

Challenge 2

Now let's implement PRESS PIN 0 in the main. Create a condition of input->on pin pressed("P0") that will add one to the score and calls the method new action.

let action  = 0;
export function newAction() {
    // ...
}
input.onButtonPressed(Button.B, () => {
    basic.showNumber(game.score(), 150)
    basic.pause(2000)
    newAction()
})
input.onPinPressed(TouchPin.P0, () => {
    if (action == 3) {
        game.addScore(1)
        newAction()
    }
})

Challenge 3

Add POINT ME NORTH to the list of possible commands.
