About this Mod

Backstube - Improved Structure Blocks Mod

Designed to stream-line frequent changes to minecraft structures when developing them.

Warning: The items are only available via the "/give @p ..." command

Required on Server AND Client to work properly!

This mod adds:

  • the Structure Export Block

    • a simplified and unlimited version of the Vanilla Structure Block
    • unlimited blocks (make sure you have enough RAM)
    • when exporting a structure e.g. "name1" it creates a backup of the previous version "name1_DATE_AND_TIME" automatically

    /give @p structuresaver:structure_export_blockitem

  • the Structure Loader

    • simplified placing/loading of structures
    • does not load structure details before placing, therefore, requires less RAM to place large structures
    • rotate with 1-click
    • unlimited blocks (make sure you have enough RAM)

    /give @p structuresaver:structure_loader_blockitem

  • the Structure Saver Item

    • quickly select two corners
    • export the structure (unlimited blocks)

    /give @p structuresaver:structure_saver

    • (based on the Structure Saver Item from the skyblock map builder mod)

This mod was created to supply one of my upcoming mods with a more convenient toolset to create Minecraft structures with no block limit.
However, the mod is independent and can be used standalone as well.
