RegionAPI

RegionalAPI is an architectural framework and core territory engine designed to partition Minecraft worlds into distinct geopolitical and ecological regions.

⚠️ Important Note:
This mod is an engine / architectural framework. Out of the box, it provides the underlying territory systems, mathematical partitioning, and discovery tools, but does not include pre-made kingdom or fantasy regions. Developers, modpack creators, or addon mods must register their own custom region definitions, names, weights, and biome overrides using this API.

Example Use :

This is example my mod what we can do with RegionAPI :

What RegionalAPI Provides for Your Regions:

• Dynamic Territory Architecture: Handles all the math and world partitioning, seamlessly organizing the map into recurring or rare unique territories.
• Built-In Regional Biome Overrides: Allows your custom regions to dynamically replace or override vanilla biomes and climates within their boundaries.
• In-Game /locate region Command: Once your custom regions are registered, players can discover them using the vanilla-style /locate region <name> command with clickable coordinates and distance tracking.
• F3 Debug Screen Integration: Automatically displays the active territory name on the F3 screen right above Biome:.
