So I am new to godot and I want a drag and drop functionality in Godot,
I was able to check an online tutorial but wasnt able to replicate the functionality as “get_drag_data(position)” wouldnt trigger ,Can someone guide me with the same please.
For what I have tried is this
1)Make 2 control nodes inside a node2d
2)one is origin and the other is the destination
3) each node has a background color and a foreground color property which are actually colorrects
4)the code for origin is as follows

extends Control

 func get_drag_data(position):
var preview = self.duplicate()
preview.modulate.a =1 
preview.get_node("color").rect_position = self.rect_size/2
return self

the code for destination is as follows :

extends Control
    func can_drop_data(position, data):
return true
   func drop_data(position, data):
$color.color = data.get_node("color").color
data.get_node("color").color = Color(randf(), randf(), randf(), 1)

The problem here is when I start drag in the origin none of the functions gets called

Can you give more info about what you’ve tried?

Your code works fine. Make sure to setup your nodes correctly as well:

  • The Control-nodes (the two children of the Node2D) have to have a rect_size bigger than Vector2(0, 0) - that will be the clickable region.
  • The ColorRect-nodes will “steal” the input if they overlap with the Control-node if the default mouse_filter is used. Set it to “Pass” or “Ignore”.

I was able to figure this out ,Thank you ,it works perfectly now …Cheers !
