Hi!
I’m trying to do a simple drag and drop, that’s why, following some samples, I’m using a connection of an Area2D input_event.
I do it in an simple scene to be instanced later in the main scene.
The scene tree:
Node2D
–Sprite (also tried out: TextureRect and Button)
–Area2D
----CollisionShape2D
Then I connect, by nodo tab, the CollisionObject2D.input_event from the Area2D to this function:
func _on_area_input_event( viewport, event, shape_idx ):
if event.is_action_pressed("left_click"):
dragged = true
print("mouse_down")
if event.is_action_released("left_click"):
dragged = false
print("mouse_up")
After that, I set the _process event true, and in the function:
func _process(delta):
#if Input.is_action_pressed("left_click"):
# dragged = true
#if Input.is_action_just_released("left_click"):
# dragged = false
if dragged:
var xoffset = get_node("img").rect_size.x/2
var yoffset = get_node("img").rect_size.y/2
var pos = Vector2(get_global_mouse_position().x-xoffset,
get_global_mouse_position().y-yoffset)
self.set_global_position(pos)
Well, if I play this scene by its own, It works perfectly, I can drag the image and drop it.
Note: As you can see, after nothing worked out, I tried the comment lines, without handling input_event. It works, but if you instance more than one copy, the move togheter at the same time, hahaha!
Then, in the main scene, I instantiate the scene by doing:
var img = load("res://scenes/draggableImage.tscn").instance()
get_node("background").add_child(img)
(background is a TextureRect, also tried with Sprite)
It’s added and it’s visible for me when playing the main scene, other things like printing a string works fine, but it’s not processing the input_event anymore (even tested with print() inside the “_on_area_input_event” function)
I don’t know why is it happening, I’m getting crazy!
Is it a bug? Should I report it?
Also, I have another minor but annoying problem.
When adding multiple instanced (draggableImage) scene into a VBoxContainer, they stack one over the other, instead of being placed one after the other in column shape.
