Hello , I'm new here .
I'm not programer at all ( don't know how to code yet ) but I'd like to know if there was a way , in expresso , to take the information ( position + rotation ) of an animated object , forward in the time ?
I'd like to make a kind of procedural walk , and I'd need to use the future postion of a controler ( the master ) , to calculate the feet position and rotation .
Do you think it's possible ? maybe you could help me with some coffee code please ^^
? that I could use in my expresso to get those values .
thanks by advance

- yes, it should be doable.You should be able to retrieve other-than the current frame in Xpresso (afaik). Definitely possible with COFFEE or C++ API.

After looking over the Xpresso nodes, it may not be possible with Xpresso alone. It may need some COFFEE since you will need to advance the frame (animate the document) to get values related to 'future' animation and then go back with that information.
In C++, one could do this less obviously by cloning the document and setting the clone's frame accordingly. Basically, to get the values of a frame, the document must be animated to that frame to account for animation tracks, expressions, and other influences. This may also be possible with COFFEE but possibly not as expedient for timely simulation.
The Xpresso Time node does get the 'current' frame/time but not sure if it can be used to get future frames. You might want to contact Srek (works for Maxon) for more information: http://www.bonkers.de. He also frequents CGTalk.org (relevant forum: http://forums.cgsociety.org/forumdisplay.php?f=182)
