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.onGesture(Gesture.LogoDown, function () {
    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.randomRange(0, 3) 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.randomRange(0, 3)
    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 in an input.onPinPressed event that, whet pin P0 is pressed, will add one to the score and then calls the newAction function.

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.
