I am beginning to think I do not quite understand the relation between cinema 4d and python.
I have a python tag with a some simple code (see below).
What I want to achieve is store data on frame x and use in frame x+1.For frame 0 it is ok, but for other frames I get the message "referenced before assignment".
I do understand the message and why it is given, but it tells me that the code is executed every frame and the variables are initialized every time.I can use userdata or the BaseContainer, that solves my issues, but I would like to understand.
I also tried global variables, but that didn't help either.What to do?
def main() :
print "\n----------\n"
frame = doc.GetTime().GetFrame(doc.GetFps())
if (frame ==0) :
varx = 0
else:
varx = varx + frameprint "varx: ", varx

Sorry, I did not search the forum before asking.
The solution is simple.
Just init the variable outside main and define it as global within main.varx=-1
def main() :
global varx
