    Hello,
    I'm just starting to try and learn coffee and would like to start out by making some simple functions. First I would like to make a coffee expression where I could have one bone aim at another bone. (pretty simple)
     
    I could use some tips/advice as to  where to start and how to go about getting that done. If there any examples around that would help too.
     
    Thanks Dave

    Oh and I would also like the bone to scale to the target bone so that you get a muscle type of bone. An aim at with scale if you get what I mean.

    Ok I have used the code from the target node that comes with C4D to work on this problem. It does all the aim at stuff already. I have added a var to get the distance between the target bone and the object bone. Now I'm stuck on how to adjust the object bones length to the distance var I have added.
    How do I go about setting the bones length to the var (dist) I have?
    Here is the code with my line added in:
    main()
    {
     var mobj = Muscle->GetMg();
     var tobj = Target->GetMg();
     
     var p1 = mobj->GetV0();
     var p2 = tobj->GetV0();
     var dist = p2 - p1; //gets distance from p1 to p2
     
     var m = new(Matrix);
     m->SetV0(p1);
     m->SetV3(vnorm(p2 - p1));
     m->SetV2(vnorm(vcross(p2-p1, vector(0,1,0))));
     m->SetV1(vnorm(vcross(p2-p1, vector(0,0,1))));
      
     Rotation=m->GetHPB();
     var orot=mobj->GetHPB();
     Rotation.z=orot.z;
     
    }

    If you drag the Length field of a bone and drop it in the C.O.F.F.E.E. editor window, you'll see that it writes "#BONEOBJECT_LENGTH". This means that you can set the length with

        
    
    op#BONEOBJECT_LENGTH = dist;

    where 'op' is the bone object.
