vkMobStacker – Advanced Mob Stacking & Lag Reduction (1.8.x – 1.20.x)

Overview
vkMobStacker is a high-performance mob stacking plugin designed to drastically reduce entity lag on Minecraft servers by intelligently merging mobs into clean, stack-based entities.


Instead of hundreds of mobs spawning in farms, grinders, or mob-heavy areas, vkMobStacker keeps a single entity with a visible stack counter, maintaining vanilla gameplay while significantly improving server performance.


Built with stability, correctness, and configurability in mind, this plugin is ideal for Survival, Factions, HCF, Residence, Prison and large production servers.




⚙ What vkMobStacker Does

Instead of this:
50 Zombies = 50 entities

You get this:
Zombie x50 = 1 entity

✔ Each kill reduces the stack by exactly 1
✔ No fake stacks, no desync
✔ Vanilla drops & XP (balanced, no abuse)


Main Features

• ✅ Automatic mob stacking on spawn
  
  
• ✅ Supports Monsters & Animals
  
  
• ✅ Clean name tag stack counter (e.g. Zombie x12)
  
  
• ✅ Correct stack decrement logic
  (1 kill = -1 from stack, always accurate)
  
  
• ✅ No multiplied drops or XP (economy-safe)
  
  
• ✅ Per-category toggles (monsters / animals)
  
  
• ✅ Global mob spawning control
  
  
• ✅ Stack-aware KillAll system
  
  
• ✅ Fully editable messages.yml
  
  
• ✅ Lightweight & performance-oriented

‍♂️ Supported Entities

• Monsters (Zombies, Skeletons, Creepers, Ghasts, etc.)
  
  
• Animals (Cows, Pigs, Sheep, etc.)

Excluded by default for safety:

• Villagers
  
  
• Armor Stands
  
  
• Players
  
  
• Bosses (Wither, Ender Dragon)

All exclusions are configurable.

KillAll System (Stack-Aware)
vkMobStacker includes a proper KillAll [/killall] system that fully respects stacked mobs.


✔ Zombie x50 counts as 50 mobs removed
✔ Reports both:

• total mobs removed
• actual entities deleted

✔ Remove all mobs with one command!
