Collision Point

[VeT]

i use

Code: Select all

   NewtonMaterialSetCollisionCallback (nworld, defaultID, defaultID, NULL, NULL, UserContactRestitution11);

***

void UserContactRestitution11 (const NewtonJoint* contactJoint, dFloat timestep, int threadIndex)
{
****
   GenericContactProcess (contactJoint, timestep, threadIndex);

   body0 = NewtonJointGetBody0(contactJoint);
   body1 = NewtonJointGetBody1(contactJoint);

   body = body0;
   NewtonBodyGetMassMatrix (body, &mass, &Ixx, &Iyy, &Izz);
   if (mass == (float)0.0) {
      body = body1;
   }
   
   void* contact;
   for (contact = NewtonContactJointGetFirstContact (contactJoint); contact; contact = NewtonContactJointGetNextContact (contactJoint, contact)) {
      NewtonMaterial* nmaterial;
      nmaterial = NewtonContactGetMaterial (contact);
      
      you = (ENTITY*)NewtonBodyGetUserData(body);
      
      NewtonMaterialSetContactElasticity (nmaterial, (float)you.skill98);
   }



how can i get point of collision for, 3d sound playing or for particles of collision ?

Code: Select all

float position[3], normal[3];
NewtonMaterialGetContactPositionAndNormal(nmaterial, position, normal);
