Nim Integration for Unreal Engine 4

This repo contains Nim library and tools that allow to create Unreal Engine 4 games on Nim programming language.

The integration is in early development, so breaking changes are possible - backward compatibility is not guaranteed yet.

This integration is being used by an indie development team to create a mobile strategy game. That game runs on iOS, Android, Windows and Mac.

Why Nim?

Nim is a native programming language that allows excellent programming productivity while not sacrificing the application's performance. It compiles directly into C++, so almost all the features UE4 provides can be made available in Nim.

Nim's syntax and semantics are simple and elegant, so Nim can be easily taught to scripters in game development teams. Nim also has rich support for meta-programming, allowing you to extend capabilities of Nim, which is great for the variety of domains a game developer usually encounters.

Features

Gameplay programming (most of the basic classes are available, more wrappers coming soon)
Blueprint support
Delegate declaration and usage support
Support for UProperty and UFunction macros and their specifiers

The integration lacks support for:

Creating editor extensions (coming soon)
Creating Unreal plug-ins with Nim
Debugging Nim code directly. But since Nim functions map to C++ functions clearly, you can use existing C++ debugging and profiling tools.
