fn and Games with Arcadia
summary
Arcadia integrates Clojure into Unity so developers write game logic in Clojure while Unity handles rendering and particles, with a Pastoral (Re-frame port) used to build a fully functional Texas Hold’em prototype that runs mostly under 60 FPS but drops to ~15 FPS during heavy event dispatch. A custom compiler called Magic aims to eliminate incidental allocations caused by interop, and Arcadia’s hybrid model uses defmutable/defrole roles to snapshot mutable Unity objects into Clojure data.
