Christian Sommerfeld posted a new comment:
First of all i created  a new hpp and a new cpp file named cone.hpp and
cone.cpp with the same code like in the cylinder.hpp and cylinder.cpp to
check if it is still working, when i only changed the name. Furthermore,
i implemented the following code into the _packPredicates.cpp file:

class inCone: public Predicate{
	Vector3r c1,c2,c12; Real radius,ht;
public:
	inCone(const Vector3r& _c1, const Vector3r& _c2, Real _radius){c1=_c1; c2=_c2; c12=c2-c1; radius=_radius; ht=c12.norm(); }
	bool operator()(const Vector3r& pt, Real pad=0.) const {
		Real u=(pt.dot(c12)-c1.dot(c12))/(ht*ht); // normalized coordinate along the c1--c2 axis
		if((u*ht<0+pad) || (u*ht>ht-pad)) return false; // out of cylinder along the axis
		Real axisDist=((pt-c1).cross(pt-c2)).norm()/ht;
		if(axisDist>radius-pad) return false;
		return true;
	}
	py::tuple aabb() const {
		// see http://www.gamedev.net/community/forums/topic.asp?topic_id=338522&forum_id=20&gforum_id=0 for the algorithm
		const Vector3r& A(c1); const Vector3r& B(c2); 
		Vector3r k(
			sqrt((pow(A[1]-B[1],2)+pow(A[2]-B[2],2)))/ht,
			sqrt((pow(A[0]-B[0],2)+pow(A[2]-B[2],2)))/ht,
			sqrt((pow(A[0]-B[0],2)+pow(A[1]-B[1],2)))/ht);
		Vector3r mn=A.cwise().min(B), mx=A.cwise().max(B);
		return vvec2tuple((mn-radius*k).eval(),(mx+radius*k).eval());
	}
};




	py::class_<inCone,py::bases<Predicate> >("inCone","Cone predicate",py::init<const Vector3r&,const Vector3r&,Real>(py::args("centerBottom","centerTop","radius"),"Ctor taking centers of the lateral walls (as 3-tuples) and radius."));

what is the same code as for inCylinder

But when i want to create an inCone with the following code:

from yade import pack
pred=pack.inCone(centerBottom=(0,0,-.1),centerTop=(0,0,.1),radius=.05)

i get the following error:

AttributeError                            Traceback (most recent call
last)

/usr/lib/yade-daily/py/yade/__init__.pyc in <module>()
----> 1 
      2 
      3 
      4 
      5 

AttributeError: 'module' object has no attribute 'inCone'

and iḿ not sure what i have to do, because there isnt any direction and file like this
/usr/lib/yade-daily/py/yade/__init__.pyc


which is
