I want to make a card game where player can stack cards on top of each other (like Solitaire or Stacklands). I have a control node as the root node and Sprite2D as the child node. The card already has dragging mechanic but I'm not sure how to create the stacking mechanic. I suppose the first step is to make the card overlap detected but I don't know how to do it with control node
thank you in advance!
You'll need to connect to the signal mouse_entered() and also check if a card is being dragged at the same time. There are a lot of different ways to do this, but one idea:
class_name Card extends Control
static var current_card: Card = null
func _ready() -> void:
mouse_entered.connect(_on_mouse_entered)
func _on_mouse_entered() -> void:
if current_card and current_card != self:
print("dragged %s into card %s!" % [current_card.get_path(), get_path()])
You'll need to set Card.current_card = <some card> when you start dragging it, and clear that by setting it to null when you're not dragging it.
