This datapack provides a funny game experience by randomizing every mob sizes in your world! 🎲 🎮
The default scale is 0.75-1.25 but can be configured as you want with the command /function random_mob_sizes:config ⚙️

The datapack is optimized, meaning it do not add any lag to your world/server! ⚡️

You can also configure per-mob behavior to fine‑tune size ranges and health scaling for specific entities. 🎯

Configuration ⚙️

Run the helper command to configure the pack:

  • ▶️ Execute /function random_mob_sizes:config
  • 💬 This prints clickable messages in chat that prefill commands you can edit and send.

What you can configure (from the in-game helper):

  • 📏 Value range for sizes: 0.0625 – 16.0
  • 🌐 Default global range: min_size = 0.75, max_size = 1.25
  • ❤️ Health scaling toggle: whether mob health scales with their size (enabled by default)
  • 🏃 Speed scaling toggle: whether mob movement speed scales with their size (disabled by default)
  • ⚔️ Damage scaling toggle: whether mob attack damage scales with their size (disabled by default)

Global settings examples 🛠️:

  • ➖📏 Set minimum size
    • /data modify storage random_mob_sizes:config min_size set value 0.75
  • ➕📏 Set maximum size
    • /data modify storage random_mob_sizes:config max_size set value 1.25
  • 🔁❤️ Enable/disable health scaling
    • /data modify storage random_mob_sizes:config health_scale set value false
    • Use true to enable, false to disable.
  • 🔁🏃 Enable/disable speed scaling
    • /data modify storage random_mob_sizes:config speed_scale set value true
    • Use true to enable, false to disable.
  • 🔁⚔️ Enable/disable damage scaling
    • /data modify storage random_mob_sizes:config damage_scale set value true
    • Use true to enable, false to disable.

Per-mob overrides (optional) 🐾:

  • 🧬 You can override the global settings for a specific mob type. Provide any subset of keys; omitted keys fall back to the global values.
  • 🐔 Example for chickens:
    • /data modify storage random_mob_sizes:config mobs."minecraft:chicken" set value {min_size:0.75,max_size:1.25,health_scale:true,speed_scale:false,damage_scale:false}
  • 🔁 Replace minecraft:chicken with the desired entity ID (e.g., minecraft:zombie).

💡 Tip: You can re-run /function random_mob_sizes:config at any time to show the clickable helpers again.

Technical / Compatibility 🔧

Mobs concerned by the datapack are:

  • mobs with a "Brain" NBT 🧠
  • not players 👤
  • not armor stands 🛡️
  • not entities having the following Tags: random_mob_sizes.checked, smithed.entity, smithed.strict, global.ignore 🏷️

Meaning modded mobs can be concerned! 🎯

If you want to revert all loaded entities to their original size, you can type /execute as @e run attribute @s scale base reset.
