O, yea , well , in the code at the end of each objet there is this geometery setting related stuff , try this
Geometry = Cylinder ; Since collision extents can't tilt, this is a little fake
GeometryMajorRadius = 8.0
GeometryHeight = 4.0
GeometryIsSmall = Yes
you will see that at end of all the objects code blocks

, if thats what you mean
