I've got a scene, made entirely of static physics objects. I've put in a function to create an explosion that scatters debris. I need the debris objects to collide with everything else, but not each other.
I know I must need to use SetObject3DPhysicsGroupAndMask() to achieve this, but I can't quite figure out how it works - if I attempt to use it, the debris won't collide with anything at all, and falls through the static plane on the ground.
The help on the AppGameKit site doesn't give any real detail... can anyone clue me in?

Thanks in advance!

This project (Posted by another member of the forum) uses SetObject3DPhysicsGroupAndMask. Maybe that will help

Hi CatfoodMcFly, I had a play with explosion forces and limited collisions.
Hope it helps.
BASIC appeared in May 1964. Lightning flashed, the wind roared and the Earth moved.
And nine months later I was born.
So here I am.
I am Basic.
Code is in my genes.

Thanks guys! I have it figured out now. Where I seemed to be going wrong was the basic understanding of how it worked, i.e. that a mask would be a group the object would collide with - from the wording, I imagined a masked group would be masked from collisions. It appears to mean the opposite!
