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!
