How to detect collisions for Area2D

Hi, I have an Area2D node (working on a user placement system for a building game) and I’m trying to implement placement validation. In other words, I want the tile to detect if the mouse is hovering over an existing tile or not.

I added a CollisionShape2Dthen attached a script to the Area2D. Connected an on_body_enteredsignal.

func _on_body_entered(body: Area2D) -> void:
	%CropsContainer.visible = false

However I don’t think the code below is executing. I looked online and it seems like this is all you need based on what I read.

Shortly after I realized I should use on_area_enteredrather than _on_body_entered
