I’m working on an town-building project.
I’m using Area2D to create building scenes so it can detect left click when I want to place it somewhere on the map. And it works fine in its own scene.
But when I try to instance it from the GUI scene (press a button from build menu), the building doesn’t detect the mouse button event anymore.
Instancing script of the GUI scene:
func _on_house_pressed():
$build_menu.hide()
var house = house_scene.instance()
get_tree().get_root().add_child(house)
pass
Building’s scripts:

Thanks.
Are you sure your mouse event is not captured by an invisible control node in top of the game? To check that when running the game, take a look at the Debugger in the editor, there is a Misc tab showing you which control you are clicking

It said that “Clicked Control” is “root/gameui” (the top one of the GUI scene).

What is gameui? Is it just a Control? Are you listening for input on this one? If not, set its mouse mode to Ignore. By default, Control nodes block mouse input, so there is a chance it caused input events to never reach the game behind.

Yeah, “gameui” is actually a Control node. I understood. Thank you very much !
