moving layer when key pressed

Martial

Hi,

I am trying to add an interaction. It consists in moving a layer on Y axis when a key is pressed.

The media is loaded in a column. I start the column, and at on time i need to press the key to animate the layer on the Y axis at a specific rate.

For now i am able to add keyframes on a timeline but then you have to hardcode it (i need to trigger it manually). I tried also a Key interaction with accumulate but you can't manage the animation speed.

not sure i am very clear....

Hello @Martial,

If you want to control how fast your layer is moving with an interaction, a solution would be to create a simple script to do so : it could have a "speed" parameter, so you bind it to an interaction to control the speed.

See this example :

Parameter.createParameter("target layer", "Layer")
Parameter.createParameter("speed (px/s)", 1)

framerate = 60

setInterval(function() {
  speed = Parameter.get("speed (px/s)")
  layerName = Parameter.get("target layer")
  position = Millumin.getLayerPosition(layerName)
  position.x += speed/framerate
  Millumin.setLayerPosition(layerName, position.x, position.y)
}, 1000.0/framerate)

Best. Philippe
