I have a script that starts with :
class_name HS extends Area
and another script that starts with :
class_name HS_ia extends HS
The HS_ia script is empty.
Why am I not allowed to write this, inside the HS script :
if self is HS_ia: # editor ERROR
=> editor ERROR : a value of type 'HS' will never be an instance of 'HS_ia'
