Random Mob Sizes
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.
- 📏 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)
- ➖📏 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.
- 🧬 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).
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 🏷️
If you want to revert all loaded entities to their original size, you can type /execute as @e run attribute @s scale base reset.

Have something to say?
Only issue I'm having is that the health still scales even though I've disabled it using the command given. How can I fix this?
If you want to force already spawned entities to update, type: /tag @e remove random_mob_sizes.checked
Though mobs will continue to spawn to initial areas despite their size
