Game Development and Ruby
summary
Attempts to make Ruby a first-class UnrealScript replacement produce unreal_rb failed — the Ruby→UnrealScript cross‑compiler proved slow and incompatible, ending as a primitive DSL and then discarded. Practical paths shown: use libraries like gosu (C++ with SWIG, OpenGL) or higher‑level engines via JRuby (Slick2D, jMonkeyEngine), or embed a lightweight Ruby runtime. Major obstacles are GIL and concurrency, Windows support, GC/memory tuning and code obfuscation. Announces a C++ engine built around MRuby + OpenGL, with code to be released and documented.
