Metroidvania Tutorial Series - Ep. 09 | Optimizing Code: Finite State Machine | Let's Make A Metroidvania in Unity!

⚙️ Ready to take your 2D character controller to the next level? In this Unity 6 tutorial, we’ll refactor our Player controller code into a Finite State Machine — giving us cleaner logic, easier debugging, and the flexibility to expand with new mechanics down the road. This is my longest video yet (30 minutes!) — a deep dive compared to the usual 10. We’re laying the groundwork for smoother systems and future-proof architecture. We’ll cover: 🔄 Converting messy if-else checks into clear, modular states 🎯 Building a State Machine to handle switching between Idle, Run, Jump, Crouch, and Slide 🧩 Writing each state as its own script for easy tweaks and scalability 🚀 Optimizing performance and reducing bugs by centralizing and re-using important functions By the end, your character controller will be fully state-driven, setting us up for advanced mechanics and polished gameplay in upcoming videos. 🔗 Assets Used (Free for Commercial Use!)
