Trigger screenshot/export automatically?

OPENRNDR How to?

Knows everyone a way how to export or trigger the screenshot function automatically? As far as I know there is just the way with pressing the spacebar. Is there a way to hack this?

Hi Ferdinand! Welcome!

There is currently not a clean way to do it (I will keep it in mind for the next release). However, what you can do is the following to fake key presses.

fun main() {
    application {
        program {
            extend(Screenshots())
            extend {
                keyboard.keyDown.trigger(KeyEvent(KeyEventType.KEY_DOWN, ' '.toInt(), "space", emptySet()))
            }
        }
    }
}

Hey Edwin!
That’s perfect working, thanks.

This could may a stupid question but how can I set an precise interval every 2 seconds only one screenshot.

I tried this, but its nur accurate enough:

fun main() = application {
program {
extend(Screenshots())
extend {
val timer = seconds%2

        if (timer < 0.02) {
            keyboard.keyDown.trigger(KeyEvent(KeyEventType.KEY_DOWN, ' '.toInt(), "space", emptySet()))
        }
    }
}

}

As well as a map function including sin(seconds). Its also not accurate enough.

Thanks Edwin.

To achieve as close as possible interval screenshots you would introduce a timestamp (lastTime in my example), you check against the timestamp and reset it when enough time has passed.

fun main() =  application {
        program {
            extend(Screenshots())
            var lastTime = seconds
            extend {
                if (seconds - lastTime > 2.0) {
                    keyboard.keyDown.trigger(KeyEvent(KeyEventType.KEY_DOWN, ' '.toInt(), "space", emptySet()))
                    lastTime = seconds
                }
            }
        }
    }

This is exactly what I need, thank you!
