How to make a text or view to blink in KorGE

[soywiz]

To make a text or any other view to blink, you can attach a interval to it, and toggle the view visibility visible property in each execution:

val text = text("hello", textSize = 64.0, alignment = TextAlignment.CENTER).xy(width * 0.5, height * 0.5)
text.interval(0.3.seconds) {
    text.visible = !text.visible
}

You can set an interval with text.timers.interval(...) or with its shortcuts text.interval(...). It will attach a timer to the view, that will be executed at the right speed based on its hierarchy speed property. The timer will only work while the view is attached to the stage, and won't produce any leak if the view is removed from the stage and no references to the view are remaining.
