I know this may sound dumb but If I create a character in blender and make it an actor then the actual physical arora of the character emits from the center in a circle pattern. How can I make the touch sensetive part of the object cover the entire mesh and not just emit in a sphere from the center? If say my object was a cube?
Yea, I’ve always had the same problem,I don’t think there is a solution.
But if there is, i’ll be very happy 
You can select other bounds like box, cylinder, polyheder or polytope. The last two are pretty much per polygon but they are slow and very buggy. 
Sphere’s still the most bug free option right now.
EDIT: sphere is the only option if you’re using a blender version before 2.33
Okay that’s what I thought, but what if say I were creating dominoes and wanted to push only one, each succesive domine would fall on it’s own, how would you work around this problem?
Use Ipos 
or wait for Blender’s game engine to get expanded
yeah but that’s no fun!
I played with dominoes before and had a curve, it would do the straight part good but then when it got to one facing a different direction it went right through it
