You can define the frame in which the layer should stay. You could think of this as an invisible parent layer of your draggable layer.
With the following
constraints, we restrict
blueSquare’s movement to 100 points from the screen’s boundaries:
# constraining dragging to 100 points from the sides blueSquare.draggable.constraints = x: 100 y: 100 width: Screen.width - 200 height: Screen.height - 200
You can also limit the movement of a layer to just one direction.
The following line of code will disable all vertical movement so that the layer can only be dragged horizontally:
# no vertical dragging blueSquare.draggable.vertical = no
And of course, there’s also
draggable.horizontal; both will be
yes by default.
