getTranslation is not working or I'm doing something wrong.

[Anonymous]

Hey guys, using the C++ maya API to get the position of a object, I am using: 

  MFnTransform fn(obj);
  
  MVector Translation = fn.getTranslation(MSpace::kTransform);

  std::string s = std::to_string(Translation.x);
  MString m(s.c_str());
  cerr << m << endl;

  std::string ss = std::to_string(Translation.y);
  MString mm(ss.c_str());
  cerr << mm << endl;

  std::string sss = std::to_string(Translation.z);
  MString mmm(sss.c_str());
  cerr << mmm << endl;

But It's not assigning / I'm using the wrong class to get the XYZ,

Hi,

MFnTransform seems working fine, could it be wrong at where you getting the object? I've just tested it with Maya 2017 with code below.

import maya.OpenMaya as om

selList = om.MSelectionList()
om.MGlobal.getActiveSelectionList(selList)

obj = om.MObject()
selList.getDependNode(0,obj)
fnTransform = om.MFnTransform(obj)

vec = fnTransform.getTranslation(om.MSpace.kTransform)
print vec.x,vec.y,vec.z

Yours,

//...   
  MItDependencyNodes it(MFn::kMesh);

  while (!it.isDone()) {
    MObject m(it.item());
    CenterOrign(m);
    it.next();
  }
//...

void MyPlugin::CenterOrign(MObject& obj) {
    MFnTransform fn(obj);
    MVector Translation = fn.getTranslation(MSpace::kTransform);
}



And I can't check to see if it's assigned so I'm kinda lost here. 

Thanks for your reply! 

The only thing I can think of is that I am assigning KMeshs as my MObject. Do you know if I am able to call getTranslation on a kMesh?

Hi,

I am afraid you have to call it with transform nodes.
