Hi Buddies

I’m on Ubuntu 10.10 and download the new panda 1.72 (great work!) an his samples programs. No on of Particles sample work :neutral_face:

from Tut-Steam-Example i got this error code

Assertion failed: okflag at line 784 of panda/src/express/virtualFileSystem.cxx
Traceback (most recent call last):
  File "Particles/Tut-Steam-Example.py", line 86, in <module>
    w = World()
  File "Particles/Tut-Steam-Example.py", line 64, in __init__
    self.loadParticleConfig('steam.ptf')
  File "Particles/Tut-Steam-Example.py", line 70, in loadParticleConfig
    self.p.loadConfig(Filename(file))

    data = vfs.readFile(filename, 1)
AssertionError: okflag at line 784 of panda/src/express/virtualFileSystem.cxx

and for Tut-Particle-Panel i got this

Tut-Steam-example don’t run.
Tut-Particle-Panel run … but not save files.
Some ideas to deal with this?

thanx

It looks to me like your .ptf files are missing for some reason?

It could be in Tut-Steam-Example but all the files are in same folder (included steam.ptf) :confused:

Some Crazy idea? Create particles from code is a little boring … :frowning:
