UnrealSharp

UnrealSharp is a plug-in developed for UnrealEngine 5. Through this plug-in, you can use pure C# to develop UnrealEngine 5 projects.

Main Features

• Support C# Hot Reloading in non-playing state
• Supports .NET 6.0~.NET 8.0 [default is .NET 8.0], supports C#12
• Supports creating new Unreal classes, Unreal structures, Unreal enumerations, etc. in C#
• Supports creating new Unreal properties, Unreal functions, and Unreal multicast delegates for C# class.
• Supports C# classes to inherit Unreal C++ classes, which means you can implement your own UObject, UActorComponent, and AActor subclasses in C#
• Supports overriding C++ Event functions in C#
• Support access to all C# classes, structures, enumerations, methods, delegates, etc. from Unreal Blueprints
• Supports Unreal Blueprint classes inheriting C# classes and overriding all C# UFunctions in blueprints
• Support debugging C# code through Visual Studio or Rider, and support simultaneous debugging of C++ and C#
• When the C# code you write does not comply with Unreal Sharp's specifications, you will get a compilation error during the compilation phase. At the same time, UnrealSharp will tell you the error type of the error code, the code file and the line number. You can jump directly with a double-click. This No different than a normal C# compilation error.
• Supports automatically generating corresponding C# binding code for Unreal C++ or Unreal Blueprint [optional]. As long as Unreal's classes, structures, enumerations, functions, etc. can be accessed in blueprints, almost all of them can be accessed in C#.
• Most C++ APIs are automatically generated as versions based on C# Function Pointers to improve calling speed.
• This interactive function framework based on C# Function Pointers is public. You can register a new C++ API with the framework if necessary.
• Automatically align Unreal and C# memory management and object lifetimes so you almost never have to handle anything yourself.
• The style of C# binding code remains the same as Unreal C++, and there is almost no difference between calling these C++ interfaces and in C++.
• AOT friendly, support for AOT has been considered from the initial design.
• Pure plug-in design, you don’t need to modify any engine source code
• In addition to the three special projects reserved by the framework, you can add any number of C# projects, and it also supports implementing corresponding Unreal types in these projects.
