Quick example

from panda3d_steamworks import SteamApps, SteamCallbackManager

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

    SteamApps.shutdown()

A steam_appid.txt file containing your app ID must be present in the working directory, or your game must be launched through Steam.

Architecture

All classes are static — you call methods directly on the class (e.g. SteamApps.init()) rather than creating instances. Async operations accept a Python callable as the last argument; the callback receives a dict with the result fields.

You must call SteamCallbackManager.run_callbacks() every frame to pump both async call-results and broadcast events. In Panda3D, this is typically done via a task:

from direct.showbase.ShowBase import ShowBase
from panda3d_steamworks import SteamApps, SteamCallbackManager

class MyApp(ShowBase):
    def __init__(self):
        super().__init__()
        SteamApps.init()
        self.taskMgr.add(self.steam_task, "steam_callbacks")

    def steam_task(self, task):
        SteamCallbackManager.run_callbacks()
        return task.cont
