DistributedObject setLocation issue

Scripting Issues
1

Hello everyone! I’m here because I’m Veeeeeeery stumped on an issue I’ve encountered recently, I’m not quite sure what to put down in all honesty, I have the error output, and last piece of code that is called before everything goes kaput.
The error:

  File "otp/avatar/DistributedPlayer.py", line 93, in setLocation
    DistributedAvatar.DistributedAvatar.setLocation(self, parentId, zoneId)
  File "/usr/share/panda3d/direct/distributed/DistributedNode.py", line 49, in setLocation
    DistributedObject.DistributedObject.setLocation(self, parentId, zoneId)
  File "/usr/share/panda3d/direct/distributed/DistributedObject.py", line 497, in setLocation
    self.cr.storeObjectLocation(self, parentId, zoneId)
AttributeError: 'NoneType' object has no attribute 'storeObjectLocation'

The code that is last called:

    def setLocation(self, parentId, zoneId):
        DistributedAvatar.DistributedAvatar.setLocation(self, parentId, zoneId)
        if not (parentId in (0, None) and zoneId in (0, None)):
            if not self.cr._isValidPlayerLocation(parentId, zoneId):
                self.cr.disableDoId(self.doId)
                self.cr.deleteObject(self.doId)
        return None

I’m running on Panda3D cloned from the github repo. I’ll try to provide any feedback I can. Any help would be super appreciated!

This means that your object is trying to set it’s location to your ClientRepository, but it (for some reason) doesn’t doesn’t know about it. In most cases, if the object comes from the server, (assuming that your ClientRepository is a subclass of ClientRepositoryBase) ‘cr’ should be defined with itself upon object generation. Otherwise, you would have to define it yourself.

But honestly, I think I can help out a bit better if you could explain what you’re trying to do here with your object.

Well, I’m not entirely sure, this is some old Toontown source code that I’ve been attempting to get up and running on the latest version of Panda3D available, (with Astron support). I’ve gotten over a lot of the hurtles but this has me stumped, this function is being called when the player moves from one location to another, such as attempting to walk into a building, or enter a tunnel, if you’re not familiar with Toontown terminology a tunnel just takes you to a different area of the game. The best I can do I suppose is post the entirety of the error code.
This used to work on an older version of Panda3D, but obviously something has changed quite a lot haha.

Just in case anyone else ever runs into this issue, I figured out that Astron has a regression that disables the client. The fix was to use an older version of Astron, release 0.1.0 is what I’m currently using.
