Question 1

How do I add Facepunch.Steamworks to my Unity project?

Accepted Answer

Download the single C# DLL, reference it in your project, and initialize SteamClient with your App ID in a try-catch block as shown in the README. It works with both Mono and IL2CPP backends without extra setup.

Question 2

Facepunch.Steamworks vs Steamworks.NET: which is better for C#?

Accepted Answer

Facepunch.Steamworks offers a more modern, object-oriented API with async support and no native dependencies, while Steamworks.NET is older but has a larger community. For new projects, Facepunch is often preferred for its cleaner design and MIT license.

Question 3

Does this library support Steam Cloud saves on all platforms?

Accepted Answer

Yes, it supports Steam Cloud across Windows, Linux, and macOS, with simple FileRead/FileWrite methods as demonstrated, but ensure the Steam client is running and the user is logged in.

Question 4

Can I use Facepunch.Steamworks for server authentication without Unity?

Accepted Answer

Yes, the Auth example in the README shows how to handle session tickets on dedicated servers using C#, but you'll need to manage network communication and error handling separately.

Question 5

What happens if Steam isn't running when I initialize the library?

Accepted Answer

Initialization will fail with an exception, as shown in the try-catch examples, so you must handle this gracefully by checking for Steam's presence or prompting users to launch it.

Question 6

How to query workshop items with specific tags in C#?

Accepted Answer

Use the Ugc.Query.All.WithTag().MatchAllTags() pattern from the README, which returns async results for filtering, but be aware of rate limits and performance with large result sets.
