Hi

I’m trying to make tween animation to specific point of Line2D.

var tween := create_tween()
tween.tween_property($Line2D, 'points[1]', Vector2(48, 48), 1.0)

but somehow it cannot find points[1], it throws error that type are missed Nil → Vector2.

I tried also to set the whole points array

tween.tween_property($Line2D, 'points', PackedVector2Array([start, end]), 1.0)

but this works without animation.

Does anybody know how to easily animate Line2D with tween?

ok, i found the answer. just need to use tween_method, something like

    var tween = create_tween()
	tween.tween_method(func(interpolate_position: Vector2) -> void:
		$Line.points = [position, interpolate_position],
	from, to, 0.4)

I tried this but it still doesn’t work

So I have 3 points and I want to draw 3 lines reaching out to the 3 points.

var init_points = [Vector2.ZERO, Vector2.ZERO, Vector2.ZERO, Vector2.ZERO, Vector2.ZERO, Vector2.ZERO, Vector2.ZERO]
var target_points = [Vector2.ZERO, to_local(point1.global_position), Vector2.ZERO, to_local(point2.global_position), Vector2.ZERO, to_local(point3.global_position), Vector2.ZERO, ]
var tween = create_tween()
tween.tween_method(func(points: Array) -> void: $Line.points = points), init_points, target_points, 1)
