Object Use Color Property

I have script that changes the objects display color. First turning on the Use Color option with this code:

obj = doc.GetActiveObject()
bc = obj.GetData()
bc.SetLong(c4d.ID_BASEOBJECT_USECOLOR, 2)
obj.SetData(bc)

It even prints the correct value when I print GetLong, but the object doesn't change?

We're supposed to use the Get&Set Parameters method as much as possible. And only use BaseContainers as a very last resort.

In Python. That means using a bracketed syntax like this:

import c4d  
def main() :  
  obj = doc.GetActiveObject()  
  obj[c4d.ID_BASEOBJECT_USECOLOR]=2     #Equivalent to SetParameter() in C++     
  c4d.EventAdd()  
  
if __name__=='__main__':  
  main()

Thanks Scott! I was racking my brain over that simple problem. Still seems like the base container should have worked though.

BaseContainers don't work for everything. For example, you can't get the attributes of a light that way - you have to use Get/SetParameter.

Thanks spedler, I guess I'm not really sure why someone would use a BaseContainer then?

Most parameters are accessible and modifiable via the BaseContainer, but not all. Using the container
directly offers certain advantages in speed (especially when using the fixed-type setters and getters)
and usage (eg. merging containers).

The things we grab using Get&Set Parameters are set up to work that way by Maxon.
So it's considered a convenience.
Plus it's also considered a safer way to work. Since you're using code they set up for us to use.

The containers are there in case you want to be a mad scientist.
They let us create something brand new on our own that Maxon hasn't set up for us already.

Thanks for clarifying this confusing topic guys! Ill stick to the get/set. It really is much easier to work with.
