What schematic4j is

schematic4j is a Java library for loading and reading Minecraft schematic files. It supports Sponge Schematic (.schem), Litematica (.litematic), and Schematica (.schematic) formats; Sponge files in versions 1, 2, and 3 are listed as supported. A Java project can load a file with `SchematicLoader.load()` and access its name, dimensions, and blocks, including the block at a chosen coordinate. The usage example also shows access to collections of blocks, block entities, and entities. The README provides Gradle and Maven instructions for version 1.1.0, available from Maven Central, and links to JitPack for development builds. Release notes for 1.1.0 list support for Litematica and Schematica, reduced memory use for Sponge schematics, and iterator changes that return positions with blocks. They also deprecate `SchematicUtil` in favor of `SchematicLoader`. The project is free and uses the MIT License, which permits use, modification, distribution, and sale subject to its conditions. The license provides the software as is, without warranty.

Good

  • Supports .schem, .schematic, and .litematic files.
  • Exposes dimensions, blocks, block entities, and entities.
  • Version 1.1.0 is available through Maven Central.
  • Uses the MIT License.

Watch out

  • The MIT License provides no warranty.
  • It is a Java library added as a project dependency.

Who it suits

schematic4j is for Java developers who need to load Minecraft schematic files and work with their contents in a Gradle or Maven project.

Verdict

schematic4j offers Java projects a focused way to load three Minecraft schematic formats and inspect their contents. It is free, but its MIT license provides no warranty.
