Problem with multiple physics

hi

im using multiple bulltappstates at my game

i turn on the parallel threading in each state using

setThredingType

i added some rigid bodycontrols to each state using

bulletappstate.getPhysicsSpace().add();

im using debug mode on each state and i can see all the right colshapes

but still there is no colliision detectioon( stuff goes throught solid stuff)

anybody got an idea for a solution?

You don’t get collisions between multiple spaces, thats not the point.

so how can i get colissions between multiple spaces.the idea is i want

each bulletappstate to acts as a trigger for setting alot of controles on and off.
