My problem is this, i have one variable driving two operations. The user selects a face and from that selection i get the face number and obj name. I've tokenised the variable to get the correct sections of the DAG path for the individual obj name and face name. The code is this...
# Select Object selected = om.MSelectionList() om.MGlobal.getActiveSelectionList(selected) selectedObj = [] selected.getSelectionStrings(selectedObj) # Tokenize the Node selection. Now faceObjList[0] is the object and faceObjList[1] # is the face Number reg = re.compile( "([^.]+)\.\w+\[(\d+)\]$" ) faceObjList = reg.match( selectedObj[0] ).groups() I then need to use the obj and face number to drive two differnt api operations. Which are these... # Uses current obj object = faceObjList[0] selectionList = om.MSelectionList() selectionList.add(object) mDagPath = om.MDagPath() mObj = om.MObject() selectionList.getDagPath(0, mDagPath, mObj) # Uses current selected face faceNumber = faceObjList[1] space = om.MSpace.kWorld vector = om.MVector() fn = om.MFnMesh(mDagPath) fn.getPolygonNormal(faceNumber, vector, space) Where as the selected object operation seems to have no problem accepting the faceObjList[0] variable, the face selection operation does. Every time i run the code it comes up with the following error ... # File "C:\engserv\rbuild\194\build\wrk\optim\runTime\Python\Lib \site-packages\maya\OpenMaya.py", line 4368, in getPolygonNormal # TypeError: in method 'MFnMesh_getPolygonNormal', argument 2 of type 'int' # I'm not sure what the problem is though i suspect it has some thing to do with me using the wrong container for the variable. If any one can offer any help that would be fantastic. Compleatly at a loss now. --~--~---------~--~----~------------~-------~--~----~ http://groups.google.com/group/python_inside_maya -~----------~----~----~----~------~----~------~--~---
