Python API to interact with BeamNG.tech.

Project description

BeamNGpy

BeamNGpy is an official library providing a Python API to BeamNG.tech, the academia- and industry-oriented fork of the video game BeamNG.drive. BeamNGpy and BeamNG.tech are designed to go hand in hand, both being kept up to date to support each other's functions, meaning using the latest versions of both is recommended.

It allows remote control of the simulation, including vehicles contained in it. See Features or go through the Feature Overview Jupyter notebook.

Features

BeamNGpy comes with a wide range of low-level functions to interact with the simulation and a few higher-level interfaces that make more complex actions easier. Some features to highlight are:

Remote Control of Vehicles

Each vehicle can be controlled individually and independently during the simulation. This includes basic steering inputs, but also controls over various lights (headlights, indicators, etc.) or gear shifting.

Throttle Control.webm

Steering Control.webm

AI-controlled Vehicles

Besides manual control, BeamNG.tech ships with its own AI to control vehicles. This AI can be configured and controlled from BeamNGpy. It can be used to make a vehicle drive to a certain waypoint, make it follow another vehicle, span the map, or follow a user-defined trajectory:

AI Trajectory

Dynamic Sensor Models

Vehicles and the environment can be equipped with various sensors that provide simulated sensor data. These sensors include:

  • Cameras
    • Color camera
    • Depth camera
    • Semantic and Instance annotations
  • Lidars
  • Inertial Measurement Units (IMU)
  • Ultrasonic Distance Measurements

Multiple cameras Lidar

These sensors give perfect data from the simulation by default. Therefore, some of them, like the camera and lidar sensor, can be equipped to also simulate noisy data.

Access to Road Network & Scenario Objects

Geometry of roads in the currently-loaded level/scenario are made available via BeamNGpy. Objects and vehicles that are currently active in the scene are also exposed, allowing for analysis of the current simulation state.

Road Network

Multiple Clients

BeamNGpy interacts with BeamNG.tech as the client, with BeamNG.tech acting as the server. This allows for multiple BeamNGpy processes to connect to a running simulation and have each control the simulator, making it possible to, for example, run a scenario in which each vehicle is controlled by a separate client.

More

There is a healthy collection of usage examples in the examples/ folder of this repository. These highlight more features, but also serve as documentation, so be sure to check them out.

Prerequisites

Usage of BeamNGpy requires BeamNG.tech to be installed. For commercial use, contact us at licensing@beamng.gmbh. Builds of BeamNG.tech are made available for research and academic use upon request using this form. Once downloaded, you can use the environment variable BNG_HOME to where BeamNG.tech can be run from, or provide a path to the BeamNGpy library during initialization.

Installation

The library itself is available on PyPI and can therefore be installed using common methods like pip:

pip install beamngpy

If you use Anaconda, you can install BeamNGpy from the conda-forge channel by:

conda install beamngpy -c conda-forge

To upgrade, use

pip install --upgrade beamngpy

if you installed BeamNGpy using pip or

conda update beamngpy -c conda-forge --no-pin

if you installed it using conda.

Usage

DISCLAIMER: If you are using an older version of beamngpy and BeamNG.tech, please follow the instructions of the corresponding README file (for example, 1.27.1 instructions). If you are using the latest version of BeamNGpy, continue following the instructions located in this README file.

The library can be imported using import beamngpy. A short usage example setting up a scenario with one vehicle in the West Coast USA map that spans the area is:

from beamngpy import BeamNGpy, Scenario, Vehicle

# Instantiate BeamNGpy instance running the simulator from the given path,
# communicating over localhost:64256
bng = BeamNGpy('localhost', 64256, home='/path/to/bng/tech', user='/path/to/bng/tech/userfolder')
# Launch BeamNG.tech
bng.open()
# Create a scenario in west_coast_usa called 'example'
scenario = Scenario('west_coast_usa', 'example')
# Create an ETK800 with the licence plate 'PYTHON'
vehicle = Vehicle('ego_vehicle', model='etk800', license='PYTHON')
# Add it to our scenario at this position and rotation
scenario.add_vehicle(vehicle, pos=(-717, 101, 118), rot_quat=(0, 0, 0.3826834, 0.9238795))
# Place files defining our scenario for the simulator to read
scenario.make(bng)

# Load and start our scenario
bng.scenario.load(scenario)
bng.scenario.start()
# Make the vehicle's AI span the map
vehicle.ai.set_mode('span')
input('Hit enter when done...')

We have a guide helping you to get started and navigating our collection of examples and the documentation of the library is available here.

Compatibility

BeamNG.tech is not a finished product but is still under development. Thus frequent changes on the simulation side are to be expected. While the BeamNGpy library maintains compatibility between minor versions for the user, this doesn't extend to the BeamNG.tech side. Not all BeamNGpy versions are compatible with all BeamNG.tech versions. Below is a list of compatible BeamNG.tech and BeamNGpy versions. However, we do not maintain minor versions: bug fixes and new features will only be available for the newest BeamNG.tech and BeamNGpy releases.

BeamNG.tech version BeamNGpy version
0.33 1.30
0.32 1.29
0.31 1.28
0.30 1.27.1
0.28, 0.29 1.26.1
0.27 1.25.1
0.26 1.24
0.25 1.23.1
0.24 1.22
0.23 1.21.1
0.22 1.20
0.21 1.19.1

Troubleshooting

This section lists common issues with BeamNGpy in particular. Since this library is closely tied to BeamNG.tech and thus BeamNG.drive, it is also recommended to consult the documentation on BeamNG.drive here:

https://documentation.beamng.com/

BeamNGpy cannot establish a connection

  • Be sure to complete the initial set-up step described in the Usage section and to repeat it with every newly released BeamNG.tech version.
  • Make sure BeamNG.tech and Python are allowed to connect to your current network in Windows Firewall.

BeamNG.tech quietly fails to launch

  • There is a known issue where BeamNG.tech quietly crashes when there is a space in the configured userpath. Until this issue is fixed, it is recommended to either switch to a path that does not contain a space or change the userpath directly in the "startup.ini" file located in the directory of your BeamNG.tech installation.
