Hi all I have a ball that is launched sort of like a angry birds situation, so basically I manage to make it all the way where you can launch the ball 3 times, and I managed to make the Arrow appear, but I have no idea how to make it rotate, any pointers would be greatly appreciated :) I marked the line with <<------ this is the line that does nothing.

extends RigidBody2D

var dragging
var drag_start = Vector2()
var drag_end = Vector2()
var launched = false
var try= 3
const Arrow = preload('res://scenes/Player/Arrow.tscn')
var arrow = null
var dir

func _ready():
    arrow = Arrow.instance()
    add_child(arrow)
    arrow.hide()

func _input(event):
    if (try != 0):
        if event.is_action_pressed("click") and not dragging and not launched:
            dragging = true
            arrow.show()
            arrow.get_rotation() <<-----------------NO ROTATION HERE, NADA
            drag_start = get_global_mouse_position()
        if event.is_action_released("click") and dragging:
            dragging = false
            launched = true
            try -= 1
            drag_end = get_global_mouse_position()
            dir = drag_start - drag_end
            apply_impulse(Vector2(), dir * 5)
            arrow.hide()
            yield(get_tree().create_timer(5.0), "timeout")
            launched = false

arrow.get_rotation() does not cause rotation to happen, it exists to give you access to the current rotation state. You need to use arrow.set_rotation(radians) or arrow.rotation = radians if you want to change the node's rotation.
