I did a small simulation using ridig bodies. I would like to write (possibly to a file) the location of each object for a specified frame. Objects are spheres with different radii.

Is it possible?

I found a small script to print the location on the command line, but it doesn't seem to work:

sphere=bpy.data.objects['Sphere01']
bpy.context.scene.frame_set(50)
print(sphere.location)

It always returns the location corresponding to the initial frame (start).

Any help?

You have to store the animation data first. Like using the bake action function: object->animation->bake actions...
