userData error!!


/* Create Cube */
NxOgre::Body* SPHERE01_BODY;
ActorParams aps;
aps.mMass = 33;
aps.mAngularVelocity = NxVec3(0,-10,0);
SPHERE01_BODY = phyScene->createBody("SPHERE01;Sphere01.mesh",new NxOgre::SphereShape(15),Vector3(0,230,0),aps);
SPHERE01_BODY->getNxActor()->userData = "123";

with userData set, there are two things happened:
1. the SPHERE01_BODY can not collide with other body
2. sometimes, ogre occurs error dialog.
Dose anyone know what is going worng? thanks for your help.

What is the reason for setting userdata?

Actually, I try to use Nxogre to do Trigger callback,but fail.
Thus, I directly use a Ageia trigger callback.
I want to know which object touchs the trigger by judging userData

You don't touch the userData. It is required for NxOgre to know which NxActor/NxShape/NxJoint is which.

If you wish to know what Actor is from another; either compare names or pointers of the Actors.
