How to delete a node by clicking on it?

Bangel

Hi, I want to make a kind of Whac-A-Mole where the mole is randomly generated on my screen. I've already managed the random generation, but I strugle to delete the mole when I click on it(not only deleting it but also doing anything else like a print).

My mole is defined by an Area2D and when I click on it a RigidBody2D goes on it. I already try to use a body_entered signal in my mole but that didn't do anything : func _on_mole_body_entered(body): print("ah!") does not work

Thanks for your help!

Do you have the signal connected? Maybe something with the signal connection is not working?

Another way you may be able to work around the issue is by using the get_overlapping_bodies (documentation) function and checking to see if the RigidBody2D is there. Something like this:

# assuming this script is attached to the Area2D
for body_in_area in get_overlapping_bodies():
	# optional: check to make sure the name of the RigidBody is "hit" or something
	# so only the rigidbody we want will trigger a print statement
	if (body_in_area.name == "hit"):
		print ("ah!")
		# for deleting, something like this *should* work
		# body_in_area.queue_free()
		break # we found the hit, so no reason to go through the other bodies.

Finally, get it! The problem was not on the signal, but on the RigidBody2D : it didn't move form his original position (I used physic_process to make it move insted of integrate_forces). I simply change the RigidBody into a KinematicBody. And thank you for the get_overlapping_body it was useful too.

Awesome! I’m glad you were able to get it working :)
