Indestructible Spawners

Spawners, trial spawners and vaults become as indestructible as bedrock. Or, if you prefer, give them a custom hardness for each difficulty.

Server-side only: install it on the server (or in your own game for singleplayer). Players don't need it.

Features

By default, in every difficulty, spawners, trial spawners and vaults:

• can't be mined outside creative mode (the mining progress stops right away, as on bedrock);
• resist every explosion like bedrock: TNT, creepers, end crystals, beds, respawn anchors, ghast fireballs, Wither skulls (blue ones included). Like bedrock, they also shield the blocks behind them;
• can't be destroyed by the Wither charging through blocks;
• can't be destroyed by the Ender Dragon flying through them.

Creative players can still break them, as with bedrock.
