Start Countdown

The game library #docs

The game library supports simple single-player time-based games. The general goal of a game will be to achieve a top score before time runs out of time.

Touch Develop

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("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)
