djitellopy-sim 0.2.2

A local DJI Tello simulator with a djitellopy-compatible Python API and 3D Pygame renderer.

DJI Tello Simulator

djitellopy-sim is a local simulator for DJI Tello programs. It exposes a djitellopy-style Tello and TelloSwarm API while rendering drones in a Pygame 3D scene instead of sending UDP commands to physical hardware.

Features

• 3D projected drone renderer with altitude, yaw, tilt, rotors, shadows, trails, and extension LED color.
• Single-drone and swarm simulation.
• Broad compatibility with djitellopy 2.5.0 method names.
• Simulated state packets, query commands, RC control, video frame reads, mission pad toggles, video settings, and Tello Talent extension commands.
• PyPI-ready packaging with automatic dependency installation.
• Uses pygame-ce for modern prebuilt wheels, including macOS universal2 wheels, while still importing the runtime module as pygame.

Installation

From a local checkout:

python -m pip install .

For development:

python -m pip install -e .

Usage

from djitellopySim import Tello

tello = Tello()
tello.connect()
tello.takeoff()
tello.move_forward(100)
tello.rotate_clockwise(90)
tello.send_expansion_command("led 0 255 255")
tello.flip_back()
tello.land()

Swarm code follows the same shape as djitellopy:

from djitellopySim import TelloSwarm

swarm = TelloSwarm.fromFile("ip.txt")
swarm.connect()
swarm.takeoff()
swarm.parallel(lambda i, tello: tello.move_up(50 + i * 10))
swarm.land()

Publishing

Update the package metadata in pyproject.toml, then build locally:

python -m pip install build
python -m build

This repository includes .github/workflows/publish.yml, which publishes to PyPI automatically when a v* tag is pushed or a GitHub Release is published.

PyPI Trusted Publishing Setup

Use PyPI Trusted Publishing so GitHub Actions can publish without a stored PyPI token.

1. Create or log in to your PyPI account at https://pypi.org.
2. If djitellopy-sim already exists on PyPI and you own it, open the project, go to Manage project -> Publishing, then add a GitHub Actions trusted publisher.
3. If this will be the first upload for djitellopy-sim, open your account Publishing page and add a pending GitHub Actions publisher for the new project name.
4. Enter these publisher values:

PyPI project name: djitellopy-sim
Owner: <your GitHub username or organization>
Repository name: <this GitHub repository name>
Workflow name: publish.yml
Environment name: pypi

5. In this GitHub repository, create an environment named pypi under Settings -> Environments. Optional but recommended: require manual approval for deployments to that environment.
6. Make sure pyproject.toml has the version you want to publish, commit the changes, push them to GitHub, then create and publish a GitHub Release.

API Parity

The simulator targets djitellopy 2.5.0. See PARITY.md for the implemented surface and the known differences from real hardware behavior.
