Issue with inheritance - Danieltr - Oct-04-2018
Hi All,
I have inherited some code and am in the process of familiarizing myself with it I have gotten stuck. When Trying to the run the code I get the following exception:
2018-10-04 13:16:40 [ERROR ] milkhub.py line:388 unhandledExceptionHandler Unhandled exception occurred:
2018-10-04 13:16:40 [ERROR ] milkhub.py line:389 unhandledExceptionHandler Type: <type 'exceptions.TypeError'>

File "/home/daniel/milkhub-dev/MILKHUBGUI/2.5/src/gui/overlays.py", line 170, in __init__
self.name = name
Starting at the 'top':
# initialise pixel2d GuiManager.pixel2d = overlays.PixelNode(app, "g2d")the __init__ function:
class PixelNode(OverlayContainer, NodePath):
# class variables
app = None
def __init__(self, app, name=None, parent=None):
PixelNode.app = app
OverlayContainer.__init__(self, name)
NodePath.__init__(self, self.name)
if parent is None:
parent = PixelNode.app.render2d
self.node = self
self.reparentTo(parent)
self.setPos(-1,0,1) #the upper left corner
self.aspectRatioChanged()which finally calls the __init__ function that throws the exception:class OverlayContainer(object):
def __init__(self, name=None, noNode=False, flip=False):
if name is None:
name = '%s%i' % (self.__class__.__name__, id(self))
[b]self.name = name[/b]
self.node = None if noNode else NodePath(self.name)
self.x, self.y = 0, 0
self.zIndex = 0
self.xScale, self.yScale = 1, 1
self.flip = flip
self.yMult = -1 if flip else 1
if self.node is not None:
self.node.setScale(self.xScale, 1, self.yScale*self.yMult)
self.node.setBin('fixed', self.zIndex)I have no idea why this is happening. If I replace self.name with self.name2 the script will work and throw an exception on the following line "self.node ..."If anyone has any insights it would be very much appreciated.
RE: Issue with inheritance - Larz60+ - Oct-04-2018
Quote:I have inherited some codeIs that the same as forces upon you?
Quote:Starting at the 'top':Looks like top should show more code.
Is it possible to show the entire code and verbatim error traceback.
At least name the imports.
RE: Issue with inheritance - Danieltr - Oct-04-2018
Correct. I will post the additional code but omit the function definitions that aren't of interest for readability sake.

RE: Issue with inheritance - nilamo - Oct-04-2018
Could you give a brief description of what this is supposed to do? I'm confused because I see panda3d (a 3d game engine), graphics drivers initialization, but then also django/jinja templating, which is for web servers rendering html.
There's also controller handling, so is it a game that connects to a remote host, and ALSO is that same remote host sometimes?
Would you be able to upload everything to github or something, so we can see the full structure and try to run it ourselves?

The ultimate error occurs in the overlays module according to the traceback. I noticed that the Milkhub class passes itself to the GUIManager which, in turn, passes the Milkhub instance to overlays.PixelNode() as the argument "app". Could you post the PixelNode function or __init__ method? That's the next breadcrumb. It evidently attempts to create an OverlayContainer which does not approve of the argument passed for "name".
