pack3d and python classes in lower directories

Scripting Issues
1

I have been attempting to start trying to convert a program I had been previously working on into a web-based app, but I am not getting very far.

My program has a number of classes set in subfolders (libs, modelclasses,etc) of the main.py folder. These folders all contain a blank init.py file and the various classes.

In my code they had been invoked like this:

from libs.User import User

where libs is a subfolder, with a blank init.py and User.py

The program packs into the p3d with no errors, but as soon as the import line is invoked it crashes with the error:

from libs.User import User
ImportError: No module named User

The code is fine running normally. What is the trick? Does ppackage.pyd have to be used? If so is it only available in the CVS?

Hmm, I think that should work. I’ll have to see if I can reproduce this problem.

I have recreated the issue with a very simple ‘program’:

main.py:

import direct.directbase.DirectStart
import os,sys

Figure out what directory this program is in.

MYDIR=os.path.abspath(sys.path[0])
sys.path.append(MYDIR)

print ‘SYS PATH’,sys.path

from libs.User import User

me=User()

run()

one folder named ‘libs’ containing a blank init.py
and User.py:

class User():
def init(self):
print “user is initialized”;

Nothing exciting, runs fine in python.
Packed with command:(the main.py in a subfolder ‘test’):

panda3d packp3d.p3d -o local_test.p3d -d test/

The output from running the above:

This is indeed a bug in packp3d, my apologies. I am working on a solution now.

I have checked in a fix for the next runtime build.
