Game Library
The game library supports simple single-player time-based games. The player has a sprite, number of lives and a score. The game has a sprite, number of levels and a countdown clock. The general goal of a game will be to move the sprite and achieve a top score before time runs out or the number of lives goes to zero.
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)
Create sprite
Create sprite with x, y coordinates and returns a LED Sprite. Create a new LED sprite.
export function createSprite(x: number, y: number) : micro_bitSprites.LedSprite
Move
Sprite move by a certain number
export function move(_this: micro_bitSprites.LedSprite, leds: number)
Turn
Rotates a sprite to the right by a certain number of degrees
export function turnRight(_this: micro_bitSprites.LedSprite, degrees: number)
Rotates a sprite to the left by a certain number of degrees
export function turnLeft(_this: micro_bitSprites.LedSprite, degrees: number)
Change
Sprite will change the x position by this number
export function changeXBy(_this: micro_bitSprites.LedSprite, x: number)
Sprite will change the y position by this number
export function changeYBy(_this: micro_bitSprites.LedSprite, y: number)
Set
Sprite will change the x position by this number
export function setX(_this: micro_bitSprites.LedSprite, x: number)
Sprite will change the y position by this number
export function changeYBy(_this: micro_bitSprites.LedSprite, y: number)
If on edge, bounce
Sprite - If the sprite is on the edge, the sprite will bounce
export function ifOnEdge_Bounce(_this: micro_bitSprites.LedSprite)
Change score by
When a player achieves a goal, you can increase the game score
- add score points to the current score
export function addScore(points: number)
Score
- 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)
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.
let running = game.isRunning()
You can also end the game by calling the game -> game over function:
game.gameOver()
