Start Countdown

The code below shows a simple game where the user gets to press the button A as much times as possible in 10 seconds.

input.onButtonPressed(Button.A, () => {
    game.addScore(1)
})
game.startCountdown(10000)

Score

When a player achieves a goal, you can increase the game score

• add score points to the current score

export function addScore(points: number)

• set the current score to a particular value.

export function setScore(value: number)

• get the current score value

export function score() : number

Countdown

If your game has a time limit, you can start a countdown in which case game->current time returns the remaining time.

• start a countdown with the maximum duration of the game in milliseconds.

export function startCountdown(ms: number)
