stop gravity on character

how can i stop the gravity effect on the character , i try with

mplayer ->getNxController()->getActor()->raiseBodyFlag(NX_BF_DISABLE_GRAVITY);

but nop,

Do you read the documentation that Ageia gives you? Or even glance at the character code?

class myVectorController {

public:

void move(NxVec3 &out, NxVec3 &moveVector, NxQuat &direction, NxVec3 &g, float t, Character*) {
// With Gravity
// out = (moveVector + g) * t;

// Without Gravity
// out = (moveVector) * t;
}
};


thanks, i had thought that exist any method in the class.
