About StackMob

From Modrinth

Enhance your server performance by 'stacking' or 'merging' entities.

Supercharge your servers' performance, without breaking grinders.

Many people (rightly so) advise against using mob stackers because of their impact on gameplay for a minuscule performance gain. StackMob offers the flexibility your server needs so you can target the worst lag offenders, without ruining the fun for everyone else.

Features:

  • Supports Paper 1.21.11+
  • Ability to blacklist certain spawn reasons, entity types or worlds to prevent stacking
  • Ability to only stack mobs if they have moved.
  • Hidable nametag - nametag only appears when the player is in close proximity or when blocks aren't in the way
  • Supports entity renaming - the nametag does not get overridden to display the stack size, rather packets are used to have a second tag.
  • Support for all entity traits (sheep colours, age, love mode etc)
  • Configurable entity event behaviours. (i.e. when a sheep is sheared you can decide whether each sheep is sheared individually or they all get sheared at once.)
  • Ability to disable stacks from targeting players.
  • Multiple death methods - different ways to decrease entity stack size. Chose from single die, all entities die, random amount die or an amount dependent on damage caused get removed.
  • Multiplication of drops, experience points and player stats on stack death.

-'Wait to stack' feature. Allows a brief period of time after initial spawn before stacking is enabled. This means that mob grinders do not get broken as entities don't merge in mid-air.

  • Support for plugins such as MythicMobs, Citizens, MyPet, Jobs, ClearLagg, McMMO and WorldGuard (a custom 'entity-stacking' flag to be used in regions)
  • Flexible Configuration! Most configuration options can be customised for specific entity types.
