Hi all,

Forgetting the easing for now. How can I move a sprite from the position of one object to the position of another?

For example, I can get the position of the two locations and imagine they end up being Vector2(100,100) and Vector2(10,10).

I’ve looked at making the sprite a child of a Kinematic2D and of a RigidBody but when I play with Vectors etc I’m only pushing/moving them in the direction of the vector. I need to know how to say Move towards 10,10.

Is there a way to do that? Of course there is :slight_smile: I just can’t find a simple answer out there is all. Can anyone lend a helping Christmas hand? :slight_smile:

So I found the answer. It turns out it’s Tweening, for anyone in the future. Here’s something to help:

export var to 			= Vector2(60,100)	#where we're moving to when we leave screen
	export var from			= Vector2(250,450)		#which part of the pipeline we travel back to
	export var speed			= 400		#fast sprite?  slow sprite?
	onready var tween = get_node("Tween")
	var property = "transform/pos"


	func _ready():
		
		#set our start position
		set_pos(from)
		moveToTarget(to, from)


	func moveToTarget(end, start):
	    var distance = start.distance_to(end)
	    var time = distance / speed

	    if tween.is_active():
		    tween.stop(self, property)
		    tween.interpolate_property(self, property, start, end, time, Tween.TRANS_LINEAR, Tween.EASE_IN)
		    tween.interpolate_property(self, "transform/scale", Vector2(0,0), Vector2(1,1), .8, Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
	    tween.start()
