Overview
Structure Gel API (mod id structure_gel) is a library and framework for Minecraft world generation. Its purpose is to give other mods a ready-made toolkit for building and placing their own structures and dimensions, so mod authors do not have to reinvent that code from scratch.
What it provides: - A structure and jigsaw building system for assembling large structures out of many pieces. - A set of special structure-gel marker blocks used while designing and generating structures (they help control how a structure carves, fills, and blends into the world, and are cleaned up during generation). - A portal framework used to build custom dimension portals. - Shared worldgen and registration helpers that dependent mods reuse.
Structure Gel API has no player-facing content of its own - it adds no real gameplay blocks, items, mobs, or mechanics you build with directly, and it does nothing visible in-game on its own. You only ever install it because another mod lists it as a required dependency.
