As question. I already have the source code for a game written for Windows. Whats a good way to port it over for the Gear VR? I hear Unreal uses C++. I wouldn't really want to recode the whole thing to C# in Unity as I don't know C#.
The game is a first person shooter and was written around mid 2000 so isn't a hugely modern game and runs on Win98, XP and 7.
Any advice appreciated.
