Hot Potato

Pass off that potato!

In this game, you will start a timer with a random countdown of a number of seconds. When the timer is off, the game is over and whoever is holding the potato has lost! Watch the tutorial on the MakeCode YouTube channel.

{Step 1}

Add an event to run code when ||input:button A is pressed||.

input.onButtonPressed(Button.A, function () {

})

{Step 2}

Make a variable named ||variables:timer|| and set it to a ||math:random value|| between 5 and 15.

The value of ||variables:timer|| represents the number of seconds left before someone is caught holding the potato.

let timer = 0
input.onButtonPressed(Button.A, function () {
    timer = randint(5, 15)
})

{Step 3}

Add code to ||basic:show an icon|| to indicate that the game has started.

let timer = 0
input.onButtonPressed(Button.A, function () {
    timer = randint(5, 15)
    basic.showIcon(IconNames.Chessboard)
})

{Step 4}

Put in a ||basic:pause|| to wait the number of seconds set in the variable ||variables:timer||. When the ||basic:pause|| completes, the game is over.

let timer = 0
input.onButtonPressed(Button.A, function () {
    timer = randint(5, 15)
    basic.showIcon(IconNames.Chessboard)
    basic.pause(1000 * timer)
})

{Step 5}

After the ||basic:pause||, add code to ||basic:show|| that the game is over.

let timer = 0
input.onButtonPressed(Button.A, function () {
    timer = randint(5, 15)
    basic.showIcon(IconNames.Chessboard)
    basic.pause(1000 * timer)
    basic.showIcon(IconNames.Skull)
})

{Step 6}

You can simplify your code by replacing ||variables:timer|| in the ||basic:pause|| with a ||math:random value|| between 5 and 15. Now, delete the other lines using the ||variables:timer|| variable.

input.onButtonPressed(Button.A, function () {
    basic.showIcon(IconNames.Chessboard)
    basic.pause(1000 * randint(5, 15))
    basic.showIcon(IconNames.Skull)
})
