Description

SteamPro – Ship on Steam Without C++.

SteamPro is a complete, Blueprint‑first wrapper around the Steamworks SDK 1.64 for Unreal Engine 4.27. It exposes every major Steam interface as clean, intuitive Blueprint nodes — 235 functions, 14 async action nodes, and 9 runtime events — so you can build achievements, leaderboards, lobbies, voice chat, overlay integration, cloud saves, Workshop support, and full peer‑to‑peer multiplayer entirely from Blueprint.

No extra setup is required: the Steamworks SDK is bundled inside the plugin. Just enter your App ID in Project Settings, press Play, and you’re connected to Steam right in the editor. When you’re ready to ship, SteamPro adds a Deploy to Steam button to the editor toolbar that packages your game and uploads it via SteamPipe — no command line, no scripts.

Why SteamPro

  • Complete coverage – 23 Steam interfaces wrapped, from User and Friends to Inventory, Workshop, Timeline, and dedicated GameServer.

  • Blueprint-first design – every node documented, categorized, and ready to drop into a graph. Steam IDs are strings, results are clean structs.

  • Editor testing – initialize Steam during Play‑In‑Editor against your App ID (or Valve’s test app 480) to verify functionality before packaging.

  • One-click deploy – package and upload straight from the toolbar.

  • Batteries included – multiplayer dashboard widget, smoke‑test actor, and BP_SteamPro_Catalog Blueprint with every node grouped by interface.

  • Production-ready C++ – async operations use proper call‑result handling; callbacks pumped every frame by a Game Instance Subsystem.

What You Can Build

  • Achievements & Leaderboards – unlock achievements, track stats, upload/download scores, query live player counts.

  • Multiplayer – create/join/browse lobbies, send P2P packets with NAT punch‑through, accept invites, run a server browser.

  • Voice chat – capture, compress, transmit, and decompress Steam voice.

  • Steam Overlay – open friends, profiles, web pages, store pages; react to overlay events.

  • Cloud saves – read/write files with quota management.

  • Workshop / UGC – query, subscribe, download, and track Workshop items.

  • Inventory & Microtransactions – manage items, definitions, consumption, and promo grants.

  • Authentication – session tickets and Web API tickets for trusted backends.

  • Additional features – Input (Steam controllers), Screenshots, Music remote, Timeline, Remote Play, Parties, Parental Settings, Video, HTTP, and dedicated GameServer/GameServerStats.
