Random Spawns

RandomSpawns not working

  • Check out the Chance of the randomspawn: if it's too low, that might be the issue, so bring it to 1 in order to check if that was the issue. If it was not, continue with the steps below without changing it back until the issue is solved.
  • Check the world difficulty: if you are trying to spawn an hostile mob type, it shouldn't be peaceful!
  • Remove any limitations, such as biome and conditions, then see if it works
  • Check if there is any mispelled word anywhere, such as:
    • the mob internal name
    • the world name
  • If the RandomSpawn starts to work after deleting all conditions, start to add them back one by one, and see which one(s) caused the issue in the first place. If you are unable to understand why the conditions thus found are problematic, ask for help over our discord
  • If the randomspawn is still not working, continue debugging by taking the actions listed below, based on the randomspawn's Action

ADD Action

  • Make sure the plugin's spawning configurations are correctly set
    • (Below MM 5.6.1): the config file is located at: /MythicMobs/config.yml
    • (MM 5.6.1 or above) the config file is located at: /MythicMobs/config/config-spawning.yml
  • Make sure you have enabled GeneraSpawnPoints in the config file, or else the ADD action will not work
  • Make sure you are in survival or adventure mode, as other gamemodes will not work
  • If all of the above fails, ask for help over our discord

REPLACE Action

  • Check the world difficulty: it shouldn't be peaceful!
  • Make sure the world can spawn monsters naturally (For instace, by making sure that the doMobSpawning gamerule is set to true and other such things).
  • Check region(World Guard, Grief Defender and so on) flags to see if the region has any flag which blocks mob spawning
