SteamPro

Quick Start

1. Enable the plugin — SteamPro lives in your project's Plugins/ folder; enabled by default.
2. Run the Steam client and log in. Steamworks requires the desktop client.
3. Set your App ID — Project Settings ▸ SteamPro ▸ SteamPro Runtime ▸ Steam Identifiers ▸ App ID (blank falls back to 480 = Spacewar).
4. Use it in Blueprint — every interface is a static function library:

Is Steam Running     → Branch
Get Local Steam ID   → Print String
Get Persona Name     → Print String

Browse every node: open BP_SteamPro_Catalog from the Blueprint Gallery — a ready-made Blueprint that catalogs and demonstrates all SteamPro nodes grouped by interface.

Steam IDs are exposed as strings (decimal uint64) since Blueprint has no 64-bit integer pin. Pass them straight back into any function that takes a Steam ID.

Editor / PIE Testing

SteamPro can initialize Steam inside the editor for Play-In-Editor testing. Because the editor isn't launched through Steam, the subsystem (under WITH_EDITOR) publishes the App ID before init: it sets the SteamAppId/SteamGameId environment variables and writes steam_appid.txt next to the editor executable. Configure in Project Settings ▸ SteamPro ▸ SteamPro Runtime.

Init App ID resolves in order: App ID → Steam Dev App ID → 480. Press Play with Steam running, then read the on-screen panel or the Output Log filtered to LogSteamPro. Shipping builds are unaffected.

Architecture

USteamProSubsystem (Game Instance Subsystem) owns the Steam lifecycle: init on start, RunCallbacks each frame, shutdown on teardown. It exposes IsSteamInitialized and every runtime event delegate.

Feature Summary

All 235 Blueprint nodes, grouped by interface. "Async" counts the latent action nodes within each group.

Blueprint data types — 11 structs (Friend, LobbyMember, LeaderboardEntry, P2PPacket, P2PSessionState, ServerInfo, InventoryItem, WorkshopItem, DigitalActionData, AnalogActionData, ControllerHandle) and 11 enums (persona state, friend flags, avatar size, lobby type, P2P send, leaderboard sort/display/upload/request, UGC query/match type).

Interface Reference

Every function safely no-ops / returns a default if Steam isn't initialized.

Not available: ISteamGameSearch was removed from Steamworks SDK 1.64 (only a leftover callback-ID enum remains), so it cannot be wrapped.

Runtime Events

Test Harness

Deploy to Steam

The SteamProEditor module adds a Steam button (with the plugin icon) to the level-editor toolbar. Its dropdown: Package & Upload, Package Game Only, Upload Existing Build, Deploy Settings. App ID and Depot ID are set once in SteamPro ▸ SteamPro Runtime ▸ Steam Identifiers (shared with runtime). The rest lives in Project Settings ▸ SteamPro ▸ SteamPro Deploy:

The uploader generates an app_build_<appid>.vdf and launches SteamCMD in a visible console so you can complete Steam Guard on first login.

Platforms

Steam Deck runs the Linux build, or the Windows build via Proton.

Troubleshooting
