Unbreakable Constructs
Unbreakable (hard as bedrock) vanilla blocks
About this Mod
Unbreakable Constructs
This mod simply adds most (non-functional) retextured vanilla blocks, that cannot be mined nor blown up
Think of the time you tried mining bedrock...
Specific use cases of this mod:
- Used alongside Eureka! Ships! for Valkyrien Skies to create ships that cannot be destroyed* (helms can still be destroyed)
- Avoid the use of plugins/area protection and instead use hard-coded hardness/resistance modifiers
Limitations:
- This mod does not prevent other mods from manipulating the unbreakable blocks (such as Mine Mine no Mi devil fruit abilities converting other blocks to Ice, etc) HOWEVER, assembled ships with unbreakable constructs blocks are safe.
