Userdata for ndBody in 4.0

[Bird]

Hi Julio,

I don't see a way to bind my scene node to ndBody like I could in 3.14

Code: Select all

// save my node as the user data for this body
NewtonBodySetUserData(newtonBody, node.get());

I need to found out which of my nodes are colliding in OnAabbOverlap() as in the demo scenes. Is there a way to do it?

Code: Select all

bool ndContactCallback::OnAabbOverlap(const ndContact* const contactJoint, ndFloat32 timestep)
{
   const ndApplicationMaterial* const material = (ndApplicationMaterial*)contactJoint->GetMaterial();
   ndAssert(material);

   const ndBodyKinematic* const body0 = contactJoint->GetBody0();
   const ndBodyKinematic* const body1 = contactJoint->GetBody1();
   const ndShapeInstance& instanceShape0 = body0->GetCollisionShape();
   const ndShapeInstance& instanceShape1 = body1->GetCollisionShape();
   return material->OnAabbOverlap(contactJoint, timestep, instanceShape0, instanceShape1);
}

When You subclass from ndBodyNotify
And there you can add all the data from you app.

Them you call body-> GetNotify().

Got it working. Thanks for the help.
