Unbreakable Constructs
by KIINGPUNCH
Unbreakable Constructs makes vanilla bedrock-style hard blocks available to build with, and its hardness changes are applied in code rather than through protection plugins.
What it does
The mod turns certain vanilla blocks into unbreakable versions that stay in place under normal mining. Its hardness and resistance values are set by the mod itself, so no area protection plugin is needed. Installation requires Forge, and the mod runs on client and server, so both the server and every player need it. Files cover 1.16.5 only, with 1.0.0 as the latest Forge file, released under All rights reserved. The source code is public, but the mod is not open source.
