This C++ example demonstrates how to create a lobby using the Steamworks SDK. It involves setting up a callback to handle the result of the lobby creation and dispatching it to the game thread.

```cpp
// You will need to declare your callback such as 
CCallResult<YourClassName, LobbyCreated_t> m_LobbyCreate_t;

// Then call create lobby which will return a SteamAPICall_t handle that can be used
// to set the m_LobbyCreate_t callback.
SteamAPICall_t handle = SteamMatchmaking()->CreateLobby(static_cast<ELobbyType>(type), maxMembers);
m_LobbyCreate_t.Set(handle, this, &YourClassName::SteamCallback);

// The SteamCallback is a function that will be invoked by the callback
YourClassName::SteamCallback(LobbyCreated_t* Response, bool bIOError)
{
	// Unreal runs callbacks on a seperate thread so you may need to dispatch the result
	// to your game thread 
	FGraphEventRef GameThreadTask = FFunctionGraphTask::CreateAndDispatchWhenReady([this, bIOError, Response]()
		{
			if (!bIOError)
			{
			
				// Callback in this context would simply be a delegate on your game thread
				if (Callback.IsBound())
					Callback.Execute(static_cast<UEResult>(Response->m_eResult), static_cast<int64>(Response->m_ulSteamIDLobby));
			}
			else
			{
				if (Callback.IsBound())

// Before you work with prices, be sure to request the prices
// This is normally done for you on initialisation
// but be sure
ItemData.RequestPrices((result, ioError) =>
{
    // if result.m_result is okay and ioError is false, all is well
});

// get the current and base price (base price is before sales/promos)
myItem.GetPrice(out ulong currentPrice, out ulong basePrice);

// get the current price as a human-friendly string ... this assumes
// the currency is based on 100 (USD, GBP, Euro, etc.)
string price = myItem.CurrentPriceString();
// and the same for base price
string basePrice = myItem.BasePriceString();

### Create Beacon in Unity

Source: https://kb.heathen.group/steam/features/party.md

Use this C# code to create a party beacon in Unity. Ensure Steam and the Parties system are initialized before calling this function. It retrieves available locations, sets join details and metadata, and then creates the beacon.

```csharp
public void CreateBeacon()
{
    // Make sure Steam and the Parties system are initialized.
    // Retrieve the list of available beacon locations.
    SteamPartyBeaconLocation_t[] availableLocations = Parties.Client.GetAvailableBeaconLocations();
    if (availableLocations == null || availableLocations.Length == 0)
    {
        Debug.LogWarning("No available beacon locations found.");
        return;
    }

    // Select a beacon location (using the first one for this example).
    SteamPartyBeaconLocation_t selectedLocation = availableLocations[0];

    // Set up the join string which provides connection details to joining players.
    string joinString = "JoinGameSessionToken123";

    // Set metadata (for example, game mode or map details).
    string metadata = "GameMode=Deathmatch;Map=Arena";

    // Set the number of open slots (e.g., if the host takes one slot and three open slots remain).
    uint openSlots = 3;

    // Create a beacon using your custom API.
    Parties.Client.CreateBeacon(openSlots, ref selectedLocation, joinString, metadata, OnCreateBeacon);
}
```

```csharp
private void OnCreateBeacon(CreateBeaconCallback_t result, bool ioFailure)
{
    if (ioFailure)
    {
        Debug.LogError("I/O Failure occurred while creating beacon.");
        return;
    }

    // Check if the creation was successful.
    if (result.m_eResult == EResult.k_EResultOK)
    {
        Debug.Log("Beacon created successfully. Beacon ID: " + result.m_ulBeaconID);
    }

### Upload, Share, and Attach UGC to Leaderboard (C++)

Source: https://kb.heathen.group/steam/features/leaderboards.md

This C++ snippet demonstrates the asynchronous process of writing a file to remote storage, sharing it, and then attaching the resulting UGC handle to a specific leaderboard. It requires setting up CallResult entries for each asynchronous operation.

```cpp
// First, we need to create our 3 CallResult entries
// File Write ASync Complete
CCallResult<YourClass, RemoteStorageFileWriteAsyncComplete_t> m_RemoteStorageFileWriteAsyncComplete_t;
// File Share Complete
CCallResult<YourClass, RemoteStorageFileShareResult_t> m_RemoteStorageFileShareResult_t;

// Next, we need to upload our file data
// Assuming
FString name; // The file name
TArray<uint8> data; // The data to upload

// Then we call the FileWriteAsync
SteamAPICall_t handle = SteamRemoteStorage()->FileWriteAsync(StringCast<ANSICHAR>(*name).Get(), data.GetData(), data.Num());
// And set the handle
m_RemoteStorageFileWriteAsyncComplete_t.Set(handle, this, &YourClass::WriteComplete);

// In your WriteComplete function
// This uses the same file name as before
void YourClass::WriteComplete(RemoteStorageFileWriteAsyncComplete_t* result, bool ioError)
{
    // Share the new file
    SteamAPICall_t handle = SteamRemoteStorage()->FileShare(StringCast<ANSICHAR>(*name).Get());
    m_RemoteStorageFileShareResult_t.Set(handle, this, &YourClass::ShareComplete);
}

// This requires you to know the Board ID you want to attach the file to
// This is the same ID you got when you "found" or "created" the board
// Now in your ShareComplete funciton
void YourClass::ShareComplete(RemoteStorageFileShareResult_t* result, bool ioError)
{
    // Attach the share handle to the target board
    SteamAPICall_t handle = SteamUserStats()->AttachLeaderboardUGC(boardId, result->m_hFile);
    m_LeaderboardUGCSet_t.Set(handle, this, &YourClass::AttachComplete);
}

void YourClass::AttachComplete(LeaderboardUGCSet_t* result, bool ioError)
{
    // The process is now complete
}

### Native Style Inventory Fetch (Unreal Engine)

Source: https://kb.heathen.group/steam/features/inventory.md

Demonstrates how to manually handle inventory result callbacks using native Steamworks SDK patterns.

```APIDOC
## Native Style Inventory Fetch (Blueprint)

### Description
This approach involves manually managing result handles and listening for global inventory result events to process inventory data.

### Steps:
1. **Request Items**: Use the native 'Get All Items' function to request items from Steam. This returns a result handle.
   - `Get All Items` (Blueprint Node)
   - Returns: `Result Handle`

2. **Listen for Results**: Bind to the global 'Inventory Result Ready' event.
   - `Inventory Result Ready` (Global Event)
   - Compares the event's `Result Handle` with the one obtained in step 1.

3. **Read Results**: If the handles match, use the result handle to read the inventory data from Steam.
   - `Read Inventory Results` (Blueprint Node)
   - Parameters: `Result Handle`
   - Returns: `Result` (EResult), `Items` (array of Item Details)
```
