A320 Render Error

FlightGear gives error when rendering with A320.

Multiplayer Flight Gear

I want to open multiple instances on flight gear. For example run code in two windows on flight gear to fly two planes on same machine. when I run your file first time , the flight gear window opens and plane start flying. when I run the file again the new window of flight gear opens and plane is on ground not flying. Then I change the port number in your visualiser.py file it did not work because it work only on 5550 if you change the port then plane is grounded not fly. PLEASE HELP ME IN THIS CASE
Thanks alot

THIS IS YOUR CODE IN visualiser.py

turn heading control task

TurnHeadingControlTask: aircraft must turn to face a random target heading while maintaining their initial altitude

I trained the model. but it is not performing turn task. Turn heading control task is same as heading control task ? what is the main difference between the two task? turn heading control task will not let the agent to turn when face the random target ? but env.render() is executing then there is no target showing

Support FlightGear 2020.4

value error coming when the command model.learn executed

model.learn(total_timesteps=10000000)
by this command , I am getting the error given below
ValueError: setting an array element with a sequ


ence. The requested array would exceed the maximum number of dimension of 1.

Training Example

Hi,

Could you please provide the code you used to for training the pre-trained models?

Thanks

Add compatibility to Linux

AttributeError: 'ArtistList' object has no attribute 'pop'

Not too sure if it's only me but human render mode doesn't work.

An abnormality in the state value of the aircraft

First of all, I would like to thank you for the great work.

I modified some of the example code you presented and turned it around as follows, and a problem occurred in the process.

import jsbgym
import gymnasium as gym

env = gym.make("F16-HeadingControlTask-Shaping.STANDARD-NoFG-v0", render_mode="graph")
env.reset()
env.render()
done = False

while not done:
    action = np.array([1, 0, 0])
    observation, reward, terminated, truncated, info = env.step(action)
    print(observation)

When the simulation was performed using the F16 model and the action was arbitrarily entered [1, 0, 0] which is 1 for aileron_cmd, 0 for elevator_cmd and 0 for rudder_cmd, and when I checked the output value of the state, only the right side of the aileron have deflection and the left side of the aileron remains zero.

In addition to the F16 aircraft, this problem also occurs on F15 and B747. Only the c172 aircraft has an acceptable value.
Do you happen to know why?

Doesn't work with FG 2020.4

FlightGear 2020.4 is opening but isn't able to visualise what is happening.
