panda3d-steamworks

Python bindings for Valve's Steamworks SDK for the Panda3D game engine.

Provides access to Steamworks features — app ownership, DLC management, language queries, and more — directly from your Panda3D Python code.

Installation

From PyPI

pip install panda3d-steamworks

From source

git clone --recurse-submodules https://github.com/DigitalDescent/panda3d-steamworks.git
cd panda3d-steamworks
pip install --no-build-isolation .

Quick start

from panda3d_steamworks import SteamApps

if SteamApps.init():
    print("Steam initialised!")
    print("Language:", SteamApps.get_current_game_language())
    print("Build ID:", SteamApps.get_app_build_id())
    print("Subscribed:", SteamApps.is_subscribed())

    # DLC
    print("DLC count:", SteamApps.get_dlc_count())

    SteamApps.shutdown()

Note: A valid steam_appid.txt file must be present in the working directory (or your game must be launched through Steam) for SteamApps.init() to succeed.

Requirements

• Panda3D SDK (with headers — the pip panda3d package alone is not sufficient for building from source)
• CMake 3.16 or higher
• A C++ compiler compatible with your Panda3D build (Visual Studio on Windows, GCC/Clang on Linux/macOS)
• panda3d-interrogate for generating Python bindings

Pre-built wheels include the compiled extension and the Steamworks shared library, so end users only need pip install panda3d-steamworks.

Building from source

# Clone with the Steamworks SDK submodule
git clone --recurse-submodules https://github.com/DigitalDescent/panda3d-steamworks.git
cd panda3d-steamworks

# Install in development mode
pip install --no-build-isolation -e .

# Or build a wheel for distribution
pip install build
python -m build --wheel

Build configuration

Build options are constants at the top of setup.py:

Constant	Default	Description
GENERATE_PDB	True	Generate a .pdb debug symbol file (Windows).
OPTIMIZE	3	Optimisation level (must match your Panda3D build).
VERBOSE_IGATE	0	Interrogate verbosity (0 = quiet, 1 = verbose, 2 = very verbose).
REQUIRE_LIB_BULLET	False	Require the Bullet physics library.
REQUIRE_LIB_FREETYPE	False	Require the Freetype library.

You can also pass options via setup.py:

• python setup.py build_ext --optimize=N
• python setup.py build_ext --clean-build — force a clean rebuild
