Pygame, Self Is Not Defined

So I'm getting this error when I compile, I don't understand though because I've got 2 identical classes, one works fine the other throws out this error. if self.currentState2==1:

Solution 1:

Your indentation is incorrect in the method calculateNextPosition. As a result, the series of if statements are executed in the body of the class (not the method), where self isn't defined.

Solution 2:

You need to indent these lines:

if self.currentState2==1:

elif self.currentState2==0: 

They are not considered part of the function def since they have the same indentation as the function name.

Solution 3:

Your indentation is off. The if statement is outside of the method you think it's in.

Solution 4:

Check your indentation - the condition is on the same level as your function definition. In other words it's not inside the function so technically yes - self is not defined.
