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.
