About this project

What does Unbreakable Spawner add?

Makes mob spawners unbreakable.

You cannot mine them.

Thats it.

Uses blockHardness = -1 as well as some data tags

I love this change in my worlds since it makes dungeons more Real and challenging, makes you build around them, or light them up or build a farm. cant just remove any blaze spawner you want etc, its there forever. Works regardless of what mob is inside.

  • Unbreakable mob spawners — regular monster spawners can no longer be mined or destroyed with any tool, same hardness as bedrock.
  • spawner block added to block/dragon_immune.json
  • Zero setup — no new items, blocks, or recipes.
  • Client + server — works the same in singleplayer and on dedicated servers.

(You probably wont need this if you are making modpacks with things like crafttweaker and zenscript, they usually have built in support for block hardness)
