Tween in Sprite node not functioning; What to do?

0 votes

This Sprite is meant to appear right below the viewport, out of sight, then use the Tween node to go to the top once Activate() is called. 

extends Sprite

var screen_size

func _ready():
    screen_size = get_viewport_rect().size
    position.y = screen_size.y
    Activate(screen_size.y)

func Activate(screen):
    var tween = $Tween
    var target = position.y - screen
    tween.interpolate_property(self, "position", position.y, target, 1, Tween.TRANS_LINEAR, Tween.EASE_OUT)
    if not tween.is_active():
        tween.start()

There are no error messages or anything, it just doesn't animate.
I've checked the values used by the tween and they seem to be exactly what I want.
Is there something about how tweens or get_viewport_rect() work that I'm missing?

You want to animate "position:y", not "position".
