Rebel Fork Framework aka rbfx is an experimental fork of Urho3D game engine distributed under MIT license.
Rebel Fork Framework is:
- Free and Open Source Software, and it will stay this way;
- Suitable for 3D games and applications;
- Moderately lightweight and modular;
- Supported for Windows, Linux, MacOS, Android, iOS, Web and XBox (via UWP);
- Just a C++ library with a couple of tools;
- Also, there are experimental, optional C# bindings.
Note: The Framework is not yet released and is undergoing active development. Backward compatibility is (mostly) preserved on resource level, but C++ API is prone to changes.
There are multiple game engines out there, both proprietary and free. Here are some reasons why you may want to try this one:
-
It's "code first" framework with full control over code execution, unlike Unity-like game engines with "IDE first" approach and script sandboxes.
-
It's portable and relatively lightweight framework that can be used like any other third-party dependency, unlike huge mainstream game engines.
-
It's a fork of the mature and stable Urho3D engine (which was released in 2011), so it's more feature-rich and well tested than many of the new non-mainstream game engines.
-
If you already use Urho3D, you may want to try this framework if you like Urho3D but you are not fully satisfied with current Urho3D feature set.
Don't use the Framework if:
-
You are not ready to write code when you need some feature. Just use Unity or any other mainstream engine with user store and ready-to-use assets.
-
You want to have cutting-edge graphics or technology for AAA game. Just use Unreal Engine or any other graphics-oriented game engine.
-
You are happy with Urho3D. This framework is not intended to be a replacement of Urho3D. Just keep using Urho3D.
-
You want Urho3D but for C#. While this framework does have C# bindings, C# is not a first-class citizen here. Try using Urho.Net or any other C#-friendly engine.
There are two template projects that you can use as example.
Empty Project is the absolute minimum of code that is required to get things running on Desktop platforms. Check it out if you don't care about recommended high-level workflow and want to do things your way.
Sample Project demonstrates recommended workflow which enables certain high-level features like writing your code once and then running it both from Editor and standalone. Sample Project is also Mobile and Web friendly and is deployed to itch.io.
Building the project is usually straighforward on Desktop platforms: standard CMake configure and build. On Mobile and Web platforms extra steps may be needed. If you cannot figure it out, check how our GitHub Actions are configured.
