Make blueprint export/import easier

[ZhiZe-ZG]

In old version BuildCraft (minecraft 1.7.10), there is a dedicated folder for Blueprints, and the blueprint files are named in a way that corresponds to their in-game names.

In the current BCCE version, I cannot find a clear location or documented format for where the Blueprints created through the Electronic Library are stored.

It looks like .bcnbt files may be related to this system, but I am not sure whether they are intended to be the actual portable/shareable Blueprint format.

Could you clarify where Blueprints are stored and how they are intended to be shared between different worlds or Minecraft instances?

Thanks for your efforts a lot.

Yes — the .bcnbt files are the actual serialized Blueprint/Template snapshot data used by the current system.

In BCCE, snapshots are stored globally for the Minecraft instance rather than inside an individual world folder.

The current locations are:

• snapshots-server/ — snapshots known to the server side
• snapshots-client/ — snapshots stored on the client side

Both directories are located directly in the Minecraft game directory.

Unlike older BuildCraft versions, the filenames are not based on the Blueprint's in-game name. They are content-addressed and use the snapshot hash/key instead, for example:

snapshot-hash.bcnbt

The human-readable Blueprint name, author, creation date and other metadata are stored in the snapshot/header rather than being used as the file name.

For moving a Blueprint to another Minecraft instance, the relevant .bcnbt file can be copied to that instance's snapshot storage. So .bcnbt is effectively the portable Blueprint data format in current BCCE, although the current UX around manually exporting/importing and identifying files is admittedly much less convenient than the old named blueprints/ directory.

In the future, I will change the storage method to make transferring easier
