Create Indestructible

Blocks made with this addon can only be broken by the player who placed them, and some of them behave unexpectedly, with glitches reported in the author text. The addon adds four new items and blocks that sit between the processing steps of Create, so they fit into an existing factory line rather than standing apart from it. Two of the processing routes make diamonds and lapis lazuli renewable, which changes how a survival world can be supplied with them.

Create must be installed for the addon to work, and the addon runs on client and server, so the server and every player need it. Files are published for Forge across six release versions, 1.20.1 – 1.20.6, and the source code and issue tracker are public. The addon is open source under the Apache License 2.0.
