Nice Mob Scaling
Randomized Mob sizes in a decent way.
About this Mod
📖 Description
Nice Mob Scaling is a lightweight data pack that dynamically adjusts the size of mobs when they spawn. By default, mobs must be exposed to the sky for their size to change, with scale variations ranging from 85% to 115% of their original size. The data pack includes easy-to-use functions that let you customize scaling behavior to suit your preferences.
🛠️ Technical Gibberish
The datapack usually just needs to be installed. There is nothing else you have to do. It just works out of the box.
PaperMC, Purpur, and similar Forks
If you are using the data pack on a PaperMC Server (or a PaperMC Fork like Purpur) make sure to set **allow-non-player-entities-on-scoreboards** in your paper config files to **true** and to include the assets file included in the data pack version to your server side resource pack in order to make everything work.How to customize valid mob types
If you are using the data pack version you can simply customize which mobs can either only shrink/grow in size or which can do both or neither. All you have to do is to add or remove the mob type in the tag lists listed below:/data/eden/tags/entity_type/valid_for_any_scaling.json
/data/eden/tags/entity_type/valid_for_enlarging.json
/data/eden/tags/entity_type/valid_for_shrinking.json
Gamerules & Command Settings
Customizing min/max values for shrinking mobs:/function mob_scaling:gamerule/range/shrink {min:<value>,max:<value>}
Customizing min/max values for enlarging mobs:
/function mob_scaling:gamerule/range/enlarge {min:<value>,max:<value>}
(Mobs valid for any scaling use the shrink min and enlarge max value)
En-/Disable if mobs need to see the sky for scaling:
/function mob_scaling:gamerule/condition/need_to_see_sky
Restore default settings:
/function mob_scaling:gamerule/default_settings
