Imagine an animation track and a sequence of objects, where there are as many objects as there are frames (one object is "assigned" to one frame). I have a sliding window that processes the objects that are relevant: say I am at frame 300, I am interested in 10 objects, numbered 290 to 300; when I am at frame 301, I am interested in 10 objects, numbered 291 to 301 etc. When I moved to frame 301 I would like to throw away object 290 and add object 301, while keeping the rest intact, including the results of the calculations done on each object.

For this window I would like to keep something like an object hashmap, keyed on object's unique ids.

Are the object unique ids available in Cinema 4d?

Thanks.

Hi eight, with nine posts 
yes there i such.
I use:

BaseObject* foo = ...
LULONG guid = foo->GetGUID();

So far I have successfully used this as a unique identifier, persistent between C4D sessions.
