Sorry, I encountered a minor issue while running tests after cloning your program.

It looks like there's an issue with the load_ic function in the jsbsim module. It seems like it's expecting two positional arguments, but only one is being given. You might want to check the documentation for the load_ic function to see what arguments it requires and make sure you are providing them correctly.

Here's the translation of my code:

import gym
import gym_jsbsim
import numpy as np
import time

env = gym.make('JSBSim-TurnHeadingControlTask-Cessna172P-Shaping.STANDARD-FG-v0')
state = env.reset()
env.render(mode='flightgear')
done = False

while not done:
    action = np.random.random((3,))*2-1
    state, reward, done, info = env.step(action)
    env.render(mode='flightgear')
    #time.sleep(1)

And the error message:

self.jsbsim.load_ic(ic_path, useStoredPath=False)
File "_jsbsim.pyx", line 954, in jsbsim._jsbsim.FGFDMExec.load_ic
TypeError: load_ic() takes exactly 2 positional arguments (1 given)

Hope this helps!

Thanks for flagging the issue.

I don't maintain this repository anymore, but it sounds like jsbsim made a breaking change to their python bindings. I see jsbsim 1.2.0 was released around two weeks ago. I would suggest trying jsbsim 1.1.x instead to see if that resolves the issue.

You're welcome! I will try again, and once again, thank you for your response.

You should replace "useStoredPath" with "booluseAircraftPath" in the code, as it has been updated in the latest version.

It should actually be useAircraftPath, not booluseAircraft Path.

In my case,
I just deleted the calling argument part ("useStoredPath=").
Instead of "load_ic(ic_path,useStoredPath=False)", "load_ic(ic_path,False)".
