Google Play Games PC SDK for Unity

The Google Play Games PC SDK for Unity provides a native C# interface for integrating Google Play Games Services on PC. This package is built specifically for the Unity engine, wrapping the underlying C++ SDK to provide a modern, type-safe, and asynchronous API for C# developers.

The Unity package, allow integration of core features, specifically Billing and Integrity, without requiring custom native wrappers or manual C++ interop management.

Key features

  • Native C# Support: Access the full Play Games PC SDK using standard C# classes and methods. The wrapper handles all marshalling between C# and the native C++ libraries.
  • Modern Async API: All asynchronous operations use standard C# Task and async or await patterns. This replaces legacy callback mechanisms, making your code cleaner and more readable.
  • Unified Error Handling: API results use a standardized Result pattern. Check Result.IsOk to verify success or inspect Result.Code for specific error enums (For example, BillingError, IntegrityError).
  • x86 and x64 architecture support: The package includes native binaries for both x86 and x64 architectures. This lets you to build 32-bit or 64-bit versions of your game that are fully compatible with the 64-bit Google Play Games on PC runtime environment.
  • Unity Package Manager (UPM) Format: Distributed as a standard tar file with clean dependency management and version control integration.
