C# API Reference

Most functions and classes in C# API have the same names and behavior as in C++ API. The main specific features of C# API are the following:

  • Names of all methods in C# start with a capital letter.
  • All C++ setters and getters are represented by properties in C#.
  • In the C# API, you can inherit from Package and Plugin classes only once.

Special Aspects of Pointers#

You should take into account that each class of C# API has methods for managing pointers:

  • IntPtr GetPtr(); — returns the internal pointer.
  • bool IsValidPtr { get; } — returns false if the native object has been destroyed.
  • bool IsNullPtr { get; } — returns true if the native object has been destroyed.
  • void DeleteLater(); — destroys the native object.

Pointers are managed in the same way as in C++.

Differences in Function Exporting#

To export your function from C# to UnigineScript, you should use Interpreter.Function() with different postfixes instead of MakeExternFunction(). The postfix of Function shows the number of arguments (up to 8 arguments) and the type of return value:

  • no postfix - void.
  • i - int.
  • d - double.
  • f - float.
  • s - string.
  • v - Unigine.Variable (the same class as the C++ API Unigine::Variable class).

See also an example of function exporting.

View Documentation by Using Visual Studio#

You can read the documentation of some C# API methods by using the Object Browser in Visual Studio.

  1. In Visual Studio, click View -> Object Browser or press CTRL + W and then J.

    The Object Browser window will open. The Object Browser displays three panes: the Objects pane on the left, the Members pane on the top right, and the Description pane on the bottom right.

  2. Select the UnigineSharp_x64d object in the Object pane and choose the class you want to view.

  3. Specify the member in the Members pane.
  4. If the description for the selected member exists, it will appear in the Description pane.
