Collision Problems (Blend Included)

Ok, I am trying to make a game similar to Slime Voleyball, but in 3D (only on 2 axis though). Anyways, I have managed to create 2 rough blob figures, and parented them to a plane (which I will assign all the controls to I guess). Only problem is, I can’t get them to detect collision. They detect it, but go all crazy and flip out. I have 2 scenes in my blend . The first one works nicely, but does not detect the net in the middle, or fall off the edge. The 2nd one does (sort of) but they flip like crazy. The 2nd scene they are made Dynamic objects. Anyone able to look at this figure out what the problem is?

Blob VolleyBall 3D

dynamic children of dynamic objects do not detect collisions correctly.

(they act as if the world is moving by their parent’s motion. If their parent doesn’t move there no problem [unless their parent is moved from it’s inital position prior to run time, in which case the entire world is moved)

so you will have to find another way to do that if that is what you did.

Well, I mean, even the parten’t alone doesn’t work properly… I guess you’d have to see the blend to understand though.
