如何从另一个函数中选择导入对象名称

Question

编辑：我设法解决了我以前遇到的问题，但不是我创建另一个新问题，我遇到的这个问题与我猜的几乎相似？

由于我修改了一些这个脚本，我目前doingn的内容，它会启动这个UI，每当用户进口的.chan对象

目前，我试图编辑摄像机名称，这样当用户选择相机，它会将导入相机的名称继承到其名称空间。 虽然我不是很确定，但我认为customNodeTranslator类中的reader函数是读取导入相机的函数吗？

这是错误messgae：

# Error: global name 'cameraName' is not defined 
# Traceback (most recent call last): 
# File "/user_data/scripts/test/maya/plugins/chan.py", line 210, in readFileIn 
#  self.importTheChan = ChanFileImporter(chanRotationOrder) 
# File "/user_data/scripts/test/maya/plugins/chan.py", line 286, in __init__ 
#  self.cameraName = cameraName 
# NameError: global name 'cameraName' is not defined # 

这是原来的代码：

class customNodeTranslator(OpenMayaMPx.MPxFileTranslator): 
    ...  
    ... 
    ... 

    def reader(self, fileObject, optionString, accessMode): 
     self.initialWindow() 

     try: 
      fullName = fileObject.fullName() 
      print ">>> full Name is %s" %fullName 

      #self.fileHandle = open(fullName,"r") 
      camHandle = open(fullName,"r") 
      camPath = os.path.basename(camHandle.name) 
      camName = os.path.splitext(camPath)[0] 
      print ">>> This is the name: %s" % camName 

     except: 
      sys.stderr.write("Failed to read file information\n") 
      raise 

     return camName 

class chanImport(): 
    """ importing chan camera from nuke """ 
    def __init__(self, rotation): 
     self.rotation = rotationOrder 
     # create the camera 
     self.cameraName = cmds.camera(n=str(camName)) 
     self.cameraShape = self.cameraName[1] 

     cmds.select(self.cameraShape) 
     cmds.scale(0.5, 0.5, 0.5) 

下面的代码是实际的代码本身我修改前：

class customNodeTranslator(OpenMayaMPx.MPxFileTranslator): 
    ...  
    ... 
    ... 
    def writer(self, fileObject, optionString, accessMode): 
     try: 
      fullName = fileObject.fullName() 
      fileHandle = open(fullName,"w") 

      selectList = OpenMaya.MSelectionList() 

      OpenMaya.MGlobal.getActiveSelectionList(selectList) 
      node = OpenMaya.MObject() 
      depFn = OpenMaya.MFnDependencyNode() 
      path = OpenMaya.MDagPath() 
      iterator = OpenMaya.MItSelectionList(selectList) 

       animationTime = OpenMayaAnim.MAnimControl() 
    class ChanFileImporter(): 
     def __init__(self, rotationOrder): 
      self.rotationOrder = rotationOrder 
      # create the camera 
      self.cameraName = cmds.camera() 
      self.cameraShape = self.cameraName[1] 
      cmds.select(self.cameraShape) 
      cmds.scale(0.5, 0.5, 0.5)

你没有将camName传递给导入器类。事实上，在上面的例子中你根本没有调用进口商类。

如果修改chanImport所以它需要的名字，你想：

class chanImport(object): 
    """ importing chan camera from nuke """ 
    def __init__(self, camName): 
     self.desiredCameraName = camName 
     self.cameraName = None 
     self.cameraShape = None 

    def create_camera(self): 
     self.cameraName, self.cameraShape = cmds.camera(n=str(camName)) 
     cmds.select(self.cameraShape) 
     cmds.scale(0.5, 0.5, 0.5) 
     return self.cameraName 

你应该能够调用它你的读者函数中：

def reader(self, fileObject, optionString, accessMode): 
    self.initialWindow() 

    try: 
     fullName = fileObject.fullName() 
     print ">>> full Name is %s" %fullName 
     camHandle = open(fullName,"r") 
     camPath = os.path.basename(camHandle.name) 
     camName = os.path.splitext(camPath)[0] 
     print ">>> This is the name: %s" % camName 
     importer = chanImport(camName) 
     actual_cam_name = importer.create_camera() 
     print ">>> created " + actual_cam_name 
     return actual_cam_name 
    except: 
     sys.stderr.write("Failed to read file information\n") 
     raise
