A Functional Developer in the World of Games
summary
Shows that functional programming techniques can be applied inside Unity by using C# LINQ patterns and the LanguageExt library for Option/Result types, together with Unity’s ECS and Job System for parallelism. Presents two concrete projects — an interactive visual/sound/light installation and a MIDI training app — and reports that a MonoBehaviour approach fails around ~1,000 entities while the ECS implementation handles about 100k entities; also discusses practical frictions like lack of immutability ergonomics, extra boilerplate or macros, and occasional integration pain.
