[SOLVED] Debug collision geometry?

Postby ep1stle » Fri Nov 07, 2008 9:18 pm

Hey folks,

I just wanted to ask you if someone can provide me a snippet which allows me to display the collision geometry. I got it working with 1.53, but since I changed to 2.0 BETA 12 the code won't compile anymore.

Old code
Code: Select all
void CGame::DebugShowGeometryCollision (const NewtonBody* body, int vertexCount, const float* faceVertec, int id)
{
   int i;

   i = vertexCount - 1;
   vector3df p0 (faceVertec[i * 3 + 0], faceVertec[i * 3 + 1], faceVertec[i * 3 + 2]);
   for (i = 0; i < vertexCount; i ++)
    {
      vector3df p1 (faceVertec[i * 3 + 0], faceVertec[i * 3 + 1], faceVertec[i * 3 + 2]);
      irrDriver->draw3DLine(p0,p1);
       p0 = p1;
   }
}

void  CGame::DebugShowBodyCollision (const NewtonBody* body)
{
   NewtonCollisionForEachPolygonDo (body, DebugShowGeometryCollision );
}


Any help would be appreciated,
thx in advance

You have to see in the new Newton.h what are the params
of NewtonCollisionForEachBodyDo...not only 2.

(and the compiler says it).

Well, of course I know that there have to be more params, but I have no clue what to set for NewtonCollisionIterator* and void* useData in order to get it working.

The NewtonCollisionIterator is your callback, the userdata is a pointer
to same of your custom data.

Thanks for your help. After one hour of porting my app to BETA17 it finally works like a charm ;)
