headbands challenges

These challenges will teach you how to create a fun charades game to play with your friends. #docs

Before we get started

Your beginning code should look like this:

let coll = (<string[]>[])
coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
input.onLogoUp(() => {
    let index = Math.random(coll.length)
    let word = coll[index]
    basic.showString(word, 150)
})
input.onScreenDown(() => {
    game.addScore(1)
})
game.startCountdown(30000)

Challenge 1

Let's add more words for the player to act out! But first, we need to increase the time in one round to give the player more time get through all the words. Let's change the game->start countdown statement.

let coll = (<string[]>[])
coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
input.onLogoUp(() => {
    let index = Math.random(coll.length)
    let word = coll[index]
    basic.showString(word, 150)
})
input.onScreenDown(() => {
    game.addScore(1)
})

game.startCountdown(60000)

Run your code to see if it works as expected

Challenge 2

Now let's add 5 more words to our list of charade words. Right above the the line word:=coll->at(index) add 5 lines that say coll->add(""). In this example, we will add the words bicycle, telephone, sun, car, and ant but you can add whatever words you like.

let coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
coll.push("bicycle") 
coll.push("telephone") 
coll.push("sun") 
coll.push("car") 
coll.push("ant") 
input.onLogoUp(() => {
    let index = Math.random(coll.length)
    let word = coll[index]
    basic.showString(word, 150)
})
input.onScreenDown(() => {
    game.addScore(1)
})
game.startCountdown(30000)

Run your code to see if it works as expected.

Challenge 3

Remove a life using game->remove life when the screen is down using the input->on screen down event.

Challenge 4

The collection has a function random that returns a random element. Update your code to use this function instead of using math->random.

Challenge 5!

Play the game and try guessing all these words in less than 2 minutes!
