Editor's Note

This month we received several submissions about terrain generation and shader. As a niche area in data pack research, few people have covered these parts, and there are many gaps in the tutorials. However, the importance of these two areas is also obvious: developers can modify the world with a higher degree of freedom through them. Therefore, we believe that these contributions are very valuable and have greatly enriched the research gaps in this field. We also encourage more developers to invest in exploring these less-explored parts.

Minecraft Custom Structure Generation Guide

Since Minecraft version 1.18, the game has introduced powerful worldgen (world generation) customization capabilities, allowing custom structures to be fully implemented through data packs without writing complex code. This innovation opens up a whole new world for creators, allowing them to easily add unique building communities and exploration content to the game. The technical content covered in this article is theoretically applicable to all versions 1.20 and above.
