For more information about C#’s unsafe context, see Microsoft’s unsafe (C# Reference) documentation or Microsoft’s Unsafe code, pointer types, and function pointers documentation. The following example targets Windows platforms and requires the Allow ‘unsafe’ code to be enabled in the Player Settings Settings that let you set various player-specific options for the final game built by Unity. The following example code provides more detailed information about how to correctly use unmanaged function pointers. Unity supports unmanaged functions pointers as introduced in C# 9, but it doesn’t support extensible calling conventions. You shouldn’t use C# records in serialized types because Unity’s serialization system doesn’t support C# records.Users can work around this issue by declaring the type in their own projects. NET 5 and later (which Unity doesn’t support). The type is required for full record support as it uses init only setters, but is only available in.Record supportĬ# 9 init and record support comes with a few caveats. If you try to use unsupported features in your project, compilation generates errors. Extensible calling conventions for unmanaged function pointers.To pass additional options in your project, see the documentation on Platform Dependent Compilation. The Editor passes a default set of options to the C# compiler. To compile C# source code in a Unity Project, the Unity Editor uses a C# compiler.
