Hi,

The test-simple.py runs fine when I point the paths to the correct folders.
The Panda3d demo (which is more or less the kind of thing I'm working on)
Gives the following:

DirectStart: Starting the game.
Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)

     JSBSim Flight Dynamics Model v1.0 Oct  2 2010 00:50:00
            [JSBSim-ML v2.0]

JSBSim startup beginning ...

Error: attempted to load aircraft with undefined aircraft, engine, and
system paths
Traceback (most recent call last):
  File "JSBSim-Demo.py", line 393, in <module>
    world = World( )
  File "JSBSim-Demo.py", line 85, in __init__
    self.setupSimulation( )
  File "JSBSim-Demo.py", line 112, in setupSimulation
    self.fdstate = self.fdex.GetState( )
AttributeError: 'JSBSim.FGFDMExec' object has no attribute 'GetState'

The code that is relevant in this case is the following:

def setupSimulation( self ):
        self.step = 1.0 / 120.0

        self.fdex = JSBSim.FGFDMExec( )
        self.fdex.SetDebugLevel( 0 )
        self.fdex.SetAircraftPath( 'aircraft' )
        self.fdex.SetEnginePath( 'engine' )
        self.fdex.LoadModel( 'c172p' )

        #self.cb = GroundCallback( )
        #self.fdex.SetGroundCallback( self.cb )

        self.fdstate = self.fdex.GetState( )

        ic = self.fdex.GetIC( )

        ic.SetUBodyFpsIC( 0.0 )
        ic.SetVBodyFpsIC( 0.0 )
        ic.SetWBodyFpsIC( 0.0 )
        ic.SetLatitudeDegIC( 47.0 )
        ic.SetLongitudeDegIC( 122.0 )
        ic.SetPhiDegIC( 0.0 )
        ic.SetThetaDegIC( 0.0 )
        ic.SetPsiDegIC( 12.0 )
#        ic.SetAltitudeFtIC( 4.8 )

        self.fdex.RunIC( )
        self.fdex.DoTrim( JSBSim.tGround )

        #engine = self.fdex.GetPropulsion( ).GetEngine( 0 )
        #print engine
        #print engine.GetType( )
        #print dir( engine )

Did things change much since that time? In that case, maybe you can help.

I'm working on a flying game. I believe it is possible to send
and receive various flight parameters to and from JSBSim. So, in short, at
every frame in my game I need to pass the control inputs (joystick,
throttle, flaps, gear etc) to JSBSim and it needs to tell me the direction,
position, velocity etc  etc so I can update the 3d model of the plane in the
game. Can the python bindings do this? Do I need to make a script or can I
pass the values to a python object which interfaces with JSBSim?
