Area2D in Popup node?

eiajfowjifsmfsoaeij

Hey. I'm trying to make it so that an UI element popup in front of the player to prompt them to drag and drop sprite.

My approach to this was to use a Popup (since it's a GUI element and it's appearing) and to use some Area2D children to detect when the mouse is inside a drop area. Long story short, the mouse_entered and mouse_exited signals are working really badly, precisely, they're not consistently being called or are only called when I drop a sprite?

I would like to know how I could make my idea work. Is there any way to fix this or are there better nodes available for what I want to do?

Welcome to the forums @eiajfowjifsmfsoaeij!

Are you just looking to detect if the mouse is over a certain area? If so, you can use the get_global_rect function to get a Rect2 representing the Control's position and size. Then you can use the has_point function in the Rect2 and get_global_mouse_position to detect if the mouse is over the Control node. Something like this:

extends Control

var is_mouse_over_control = false

# as long as the Control node is not moving, we can just
# cache its Rect2 here
var global_rect

func _ready():
	global_rect = get_global_rect()

func _process(_delta):
	if visible == false:
		return
		# We need this so we only process the mouse when the popup is visible.
	if global_rect.has_point(get_global_mouse_position():
		# Did the mouse just enter the node?
		if is_mouse_over_control == false:
			print ("Mouse just entered Control node!")
			is_mouse_over_control = true
		else:
			print ("Mouse is still in Control node!")
	else:
		# Did the mouse just leave the node?
		if is_mouse_over_control == true:
			print ("Mouse just left Control node!")
			is_mouse_over_control = false
