This package provides a simple Steam API wrapper for common tasks like initialization, callback processing, player name lookup, and achievements.
## Features
- Simple Steam initialization via `SteamManager.Instance`
- Per-frame callback runner with `SteamManager.Update()`
- Simple Steam initialization via `SteamManager.Instance` (uses `SteamAPI_InitFlat` on SDK 1.58+ and reports the error message in `InitErrorMessage`)
- Configurable native library location with `SteamManager.ConfigureLibraryPath()` (Unity `Plugins/x86_64`, custom folders)
- `SteamManager.RestartAppIfNecessary()` for launching through Steam
- Per-frame manual callback dispatch with `SteamManager.Update()`: callback subscriptions, `OverlayActivated` event and async call results (`SteamManager.Instance.Callbacks`)
- Ownership, DLC and language queries via `SteamManager.Instance.Apps` (ISteamApps)
- Safe shutdown with `SteamManager.Shutdown()`
- Player persona name access with `SteamManager.GetSteamName()`
- Achievement helpers via `AchievementManager`

```
## Callbacks and async call results
`SteamManager.Update()` runs Steam's manual dispatch loop (`SteamAPI_ManualDispatch_*`). Callbacks and async call results are delivered from `Update()`, on the thread that calls it. If the loaded `steam_api` has no manual dispatch exports, or you call `SteamManager.ConfigureManualDispatch(false)` before `Instance`, `Update()` falls back to `SteamAPI_RunCallbacks` and no events or results are delivered. The library never runs both.
```cs
var steam = SteamManager.Instance;
// Typed overlay event (GameOverlayActivated_t)
steam.OverlayActivated += overlay => Console.WriteLine($"Overlay open: {overlay.Active}");
// Any callback by id, with the raw payload
IDisposable sub = steam.Callbacks.Subscribe(SteamCallbackIds.GameOverlayActivated, data =>
{
bool active = data.ReadBoolean(0);
});
sub.Dispose(); // unsubscribe
// Workshop results: callback style...
steam.Ugc.SubmitItemUpdate(updateHandle, "Patch notes", result =>
{
if (result.IsSuccess) Console.WriteLine($"Uploaded {result.PublishedFileId}");
if (result.UserNeedsToAcceptWorkshopLegalAgreement) { /* show the agreement link */ }
});
steam.Ugc.CreateItem(480, 0 /* k_EWorkshopFileTypeCommunity */, created => { /* created.PublishedFileId */ });
steam.Ugc.SendQueryUgcRequest(queryHandle, query => { /* query.NumResultsReturned */ });
// ...or awaitable (keep calling Update() while waiting)
var query = await steam.Ugc.SendQueryUgcRequestAsync(queryHandle);
// Any other SteamAPICall_t handle
var raw = await steam.Callbacks.WaitForCallResultAsync(apiCallHandle);
if (!raw.IoFailure) { int eResult = raw.ReadInt32(0); }
```
Callback structs use 8-byte packing on Windows and 4-byte packing on Linux, Steam Deck and macOS, which moves 64-bit fields in some structs. The typed results handle this. When you parse a raw payload yourself, check `SteamCallbackDispatcher.UsesLargeCallbackPack`.
## Using in Unity
The library has no Unity references; add the DLLs and the Steam native libraries (`steam_api64.dll` for Windows, `libsteam_api.so` for Linux) to `Assets/Plugins/x86_64/` and set their platforms in the import settings. Keep all Steam code behind your Steam-off define (for example `DISABLESTEAMWORKS`) so itch / Microsoft Store builds don't touch it.
```cs
#if !DISABLESTEAMWORKS
using System.IO;
using OmegaLeo.HelperLib.Steamworks;
using UnityEngine;
public class SteamBootstrap : MonoBehaviour
{
private const uint AppId = 480; // your AppId (full game and demo have different ids)
private void Awake()
{
DontDestroyOnLoad(gameObject);
// Player: <Game>_Data/Plugins/x86_64 (some Linux layouts use <Game>_Data/Plugins).
// Editor: Application.dataPath is Assets/, so this finds Assets/Plugins/x86_64.
SteamManager.ConfigureLibraryPath(Path.Combine(Application.dataPath, "Plugins", "x86_64"));
SteamManager.ConfigureLibraryPath(Path.Combine(Application.dataPath, "Plugins"));
#if !UNITY_EDITOR
// Relaunch through Steam when started from the exe. Call before ConfigureAppId.
if (SteamManager.RestartAppIfNecessary(AppId))
{
Application.Quit();
return;
}
#endif
#if UNITY_EDITOR || DEVELOPMENT_BUILD
// Editor/dev only: writes steam_appid.txt. Shipped builds get the AppId from Steam.
SteamManager.ConfigureAppId(AppId, writeSteamAppIdFile: true);
#endif
var steam = SteamManager.Instance;
if (!steam.IsSteamworksInitialized)
{
Debug.LogWarning($"Steam not available: {steam.InitErrorMessage}");
return;
}
steam.OverlayActivated += OnOverlayActivated;
}
private void Update()
{
SteamManager.Instance.Update(); // every frame, main thread
}
private void OnOverlayActivated(SteamOverlayActivated overlay)
{
Time.timeScale = overlay.Active ? 0f : 1f; // or your own pause logic
}
private void OnApplicationQuit()
{
SteamManager.Instance.OverlayActivated -= OnOverlayActivated;
SteamManager.Instance.Shutdown();
}
}
#endif
```
Pass an `ILogger` to `SteamManager.ConfigureLogger` (a small adapter around `Debug.Log`) to see which library path loaded and why init failed.
## Notes
- Steam must be running and your app must be launched in a valid Steam context.
- Configure your AppId before first access to `SteamManager.Instance`.
- Configure your AppId, library path and dispatch mode before first access to `SteamManager.Instance`.
- `ConfigureAppId(appId)` only sets the `SteamAppId` / `SteamGameId` environment variables. Use `ConfigureAppId(appId, writeSteamAppIdFile: true)` to also write `steam_appid.txt` (development only; a shipped build with that file skips `RestartAppIfNecessary`).
- `SteamManager.Update()` should be called continuously during runtime.
- If Steam is unavailable, `GetSteamName()` falls back to `"Player"`.
