How to detect any type of variable that is stored in an array - Godot?

Question

I have an array containing nodes as well as strings. While passing it through a loop, I want to call certain functions depending on the type of object being read. I tried to do the following to test the type -

if to_fry_array[fry_looper].is_class("Node2D"):
    to_fry_array[fry_looper].show()
else:
    print (to_fry_array[fry_looper])

The code throws an error when a string is read in the array to_fry_array. Error -

Invalid call. Nonexistent function 'is_class' in base 'String'.

How do I modify this code so that it behaves universal to all types of objects/variables?

Answer 1

Not every type has method is_class, but fortunately you can use operator typeof to achieve what you need.

if typeof(obj) == TYPE_OBJECT and obj.is_class("Node2D"):
    print("Node2D: ", obj)
elif typeof(x) == TYPE_STRING:
    print("String: ", obj)

and in your particular case:

if typeof(to_fry_array[fry_looper]) == TYPE_OBJECT and \
          to_fry_array[fry_looper].is_class("Node2D"):
    to_fry_array[fry_looper].show()
else:
    print (to_fry_array[fry_looper])
