checking for (area) not working

bkumanchik

I have a function that reads:

func _on_mug_area_entered(area):
	print(area)

and outputs:

mug_stop:[Area2D:1383]

But when I try to check for it with this:

func _on_mug_area_entered(area):
	if area is mug_stop: # this line errors
		queue_free()

I get this error:\

Parser Error: The Identifier "mug_stop" isn't declaired in the current scope.

If that's true, how come I can output the proper area to the Output window?

I was able to duplicate the issue. I don't know if it's a bug, a design limitation or expected behavior.

If you need to identify the area, you could compare the parameter to a node reference or check the group membership.

Thanks, I'll try that

Got it to work using class_name

"mug_stop" is an object, not necessarily a class. When you use "x is y", you're checking if x belongs to class y (including built-in classes). If you check against Area2D

if area is Area2D:

your code should work. If you want to be more specific, put a class_name at the top of mug_stop's script, to make it a class.

class_name MugStop

Then, check for the new class.

if area is MugStop:

That's what I did
