The game library #docs
The game library supports simple single-player time-based games. The player has a number of lives and a score. The game has a number of levels and a countdown clock. The general goal of a game will be to achieve a top score before time runs out or the number of lives goes to zero.
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(Button.A, () => {
game.addScore(1)
})
game.startCountdown(10000)
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)
Game over
If the life reaches zero or the time expires (see countdown), the game enters the game over mode. When the game is over, game->is running returns false
- check if the game still running.
export function isRunning() : boolean
Indicates if the game is display the game over sequence.
export function isGameOver() : boolean
You can also end the game by calling the game -> game over function:
export function gameOver()
