Metroidvania Tutorial Series - Mini Map (Advanced) -- Metroidvania-Style | Data Persistence in Unity | Ep. 06

Build on your Metroidvania-style minimap by adding map progression and discovery depth. In this follow-up, we upgrade the system to support multiple map states—from completely hidden, to partially revealed outlines, to fully explored rooms that display their contents. This lets you create a more immersive exploration loop where players gradually uncover the world instead of instantly seeing everything. We’ll also implement a map item system that allows you to reveal specific rooms or areas, giving you full control over how and when players gain map knowledge—perfect for rewards, shops, or key progression moments. Like before, everything is designed to fit into a scalable architecture, so your system stays clean and expandable as your game grows. 🎮 What you’ll learn in this Unity tutorial: • How to add multi-stage map discovery (hidden → mapped → visited) • How to show room outlines before full exploration • How to reveal room contents only after visiting • How to design a flexible map progression system • How to create items that reveal parts of the map • How to extend an existing minimap system cleanly 🧠 Perfect for: Metroidvania developers 2D Unity developers Exploration-focused game designers Devs looking to deepen player discovery systems 🎨 Assets used: Minimal Fantasy GUI by ETA 👉 https://etahoshi.itch.io/minimal-fantasy-gui-by-eta This video continues the Unity Scene Persistence series, where we build real-world systems that scale—focusing on clean architecture, modular design, and practical implementation.
