FAQ

Yeah! This was made with the intention of aiding modpack creators.

  • Client or Server?

This mod works all on the server side! Though players without the mod will not see the "This mob has been disabled!" message on their action bar.

How to use

You can simply stop a mob from spawning by adding it to the list in config\moberradicator.json5

Example

{
  blocked_mobs: [
    "minecraft:zombie"
  ]
}
  • This stops all zombies from spawning



{
  blocked_mobs: [
    "!minecraft:zombie_.*"
  ]
}
  • Adding an exclamation mark ! before the mob you want to remove will enable the use of regex in that string. Adding .* will determine what section of the expression must match to stop a mob from spawning, this one for example will stop both zombie villagers and zombie horses from spawning!
