[Tutor] unbound method function()

[ryan luna]

I have two Classes, I have a method in the first class (using Pygame/livewires moduls)

Class1(games.Sprite):
       function1(self):

That is being called by the second class

Class2(games.Sprite):
       function2(self):
          Class1.function1()

When the code runs i get this error

"unbound method function() must be called with Class2 instance as first argument
(got nothing instead)"

Its weird (to me) b/c i have other methods calling methods from other classes just fine, but on this one method i get that error.
