In an effort to try to figure out why the ball in Hyperspace Pinball would sometimes go through the flippers, I started a thread at Forum.unity3d.com . The response was great as a fellow developer named Hippocoder pointed out the reason for it could have been because I was not using Continuous Dynamic collisions. After implementing them, I haven't had an issue since. You can learn more about them at Unity3d.com .
In that Unity3D forum thread, I included a link to a stripped down version of Hyperspace Pinball at Gamieon.com . My hope is that Unity developers who want to make a pinball game can get a head start with it, while the Unity gurus can tweak it if they feel like. In addition to continuous collisions, it also has some of my own "black magic" to detect and prevent ball fall-throughs.
I hope Unity developers will benefit from it!
