In Godot 3 I could write:
if not variable:
do stuff
But the "not" keyword seems reserved for booleans only now.
How do we check if a variable is empty?

This is my workaround for now:
static func is_not(variable):
if variable is String and variable == '':
return true
elif variable is Dictionary and variable == {}:
return true
elif variable is Array and variable == []:
return true
elif variable is bool and not variable:
return true
elif variable is Object and not is_instance_valid(variable):
return true
elif variable is int and variable == 0:
return true
elif variable is float and variable == 0.0:
return true
return false
Since it's hard to search Godot 4 docs+info right now...
I believe the keyword is None. So.
if my_var == None:
# it's null
You could also make use of != in this scenario and just have something happen if you don't get the desired result in an if statement, don't see why it wouldn't work as that's the same as not I think? Lots of syntax changes happening in Godot 4, I'm still working it out myself.
Hmm I get "Identifier None not declared in current scope"
Sorry, it's null now.
if test == null:
That seems to be it, thanks cybereality
