by sch246
Redstone Structure Block changes where a structure block keeps its saved structures, so they can be stored on disk rather than in memory when a redstone signal triggers them.
What it does
The mod is a Fabric addition that lets structure blocks that respond to redstone save their structures to permanent disk storage instead of holding them in memory. A saved structure stays on disk and can be loaded again when a redstone signal fires the block, which fits builds that are placed and reset repeatedly.
A new game rule named redstoneSaveStructureBlock controls the behavior. It defaults to saving to disk, and it can be switched so that structures stay in memory. Because the change applies to structure blocks triggered by redstone, other structure block use is not affected. The mod requires Fabric API, and the Fabric Loader 0.16.7 must be installed alongside Minecraft 1.21.2 or a later release in the supported range.
Installation means placing the jar in the mods folder of a Fabric instance. Server owners install it, and players connect with no copy of their own. It is released under the MIT License and is open source, with source code published.
Key features
Disk-stored structures
Structures saved by a redstone-triggered structure block are written to disk instead of being kept in memory.
Redstone triggering
A structure block responds to a redstone signal, loading its saved structure each time it is triggered.
redstoneSaveStructureBlock rule
A game rule chooses between saving structures to disk, the default, and keeping them in memory.
Targeted behavior
The change applies only to structure blocks that work with redstone, leaving other structure block functions as they are.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Repeatable redstone builds
Builds that are placed and reset by redstone signals can keep their structures on disk, so a server does not need to hold every saved structure in memory.
Who it’s for: Server owners running Fabric who build redstone-driven structure systems, such as repeatable arenas, rides or contraptions that reload their layouts on command.
