People, I'm new to chipmunk and objective c and trying to write
A simple game. I have a few balls moving on the screen and have
Added a platform as a rogue body. I.e. It's a initstatic and has not
Been added to the space. Have 3 polyshapes attached to it. I want
The user to be able to move the platform using a pangesture. My
Ques is how do I get the shapes/body to keep up with the movement
Of the associated image? If there are more than one ways to do this,
Which is recommended?

Btw, I'm using objective cm for iPhone.

UPDATE: Still appreciate an answer to the above. In the meanwhile, instead of the initstatic, i'm now using a body (not added to the space) with a very high mass for my moving rogue body. Also, updating the body.pos to match the uipangesture translation. This seems to work however when i pan the rogue body (a bowl) too fast, any balls within it fall out (through the shapes)..... This is probably because, the pangesture method is called too frequently while the space is updated slower..i tried calling the transform method (for all the balls in the space) within the pangesture but this does not seem to help. How do i keep the pangesture moving roque in sync with the space updation (assuming that is the problem) ?

Hey, I'm at GDC this week and didn't bring my main development machine with so it's harder to answer more technical questions. I made myself a reminder, but give the thread a nudge if you haven't gotten an answer by Monday.
