Seven Segment Display

Examples of using the seven segment display extension.

5 Digit Counter

Create a counter with 5 digits and add one to the current count value every 100 milliseconds.

let myCounter: DigitCounter = null
myCounter = sevenseg.createCounter(SegmentStyle.Narrow, SegmentScale.Full, 5)
myCounter.count = 54321
game.onUpdateInterval(100, function () {
    myCounter.count += 1
})

Digital LCD Clock

Create 3 counters to display hours, minutes, and seconds. Set the display size of the seconds counter to half. Insert a sprite to show a colon character between the minutes and hours display. Use a color for the digits and screen background that will simulate the look of a LCD display.

let time = 0
let seconds: DigitCounter = null
let minutes: DigitCounter = null
let hours: DigitCounter = null
let ampm: SevenSegDigit = null
time = 44786
scene.setBackgroundColor(13)
seconds = sevenseg.createCounter(SegmentStyle.Thick, SegmentScale.Half, 2)
minutes = sevenseg.createCounter(SegmentStyle.Thick, SegmentScale.Full, 2)
let colon = sprites.create(img`
