Hi
I'm trying to get global variables working - I have a strange problem where if make a comparison test - I can no longer change the value afterwards without crashing.

for example...

gives the error,
UnboundLocalError: local variable 'y' referenced before assignment

Hi,

an example.

  
import c4d  
  
  
def settings() :  
  global x,y  
  x=3  
  y=6  
  return x,y  
  
def main() :  
  global x,y  
  settings()  
    
  if x != y:  
      y = 0  
      print y  
  
if __name__=='__main__':  
  main()  
  

Best wishes

you´re welcome

another one:
depends on what you´re going to do

  
  
import c4d  
  
global x,y  
x=6  
y=5  
  
  
def main() :  
  global x,y  
    
    
  if x != y:  
      y = 0  
      print y  
  
if __name__=='__main__':  
  main()
