Types And Variants
by itsjeff
Types And Variants changes mob stats and adds mob variations, so the mobs in a world look and behave less uniformly on NeoForge.
What it does
Types And Variants adds variations to existing mobs and changes their stats, so a world with the mod installed does not repeat one plain version of each creature. Its code only builds on Minecraft's own mob code, and extra data for each variant is stored under a tag named type, which keeps the variant information in the usual save data. The mod also splits Undead Armies, so the groups of undead spawn in different forms.
The mod runs on the server alone, so players join without installing anything. It is published for NeoForge and covers 1.21 – 1.21.4, with 0.0.1 for 1.21.4 as the latest file. The project is open source under the GNU General Public License v3.0 only, and public links to its source code, issue tracker and wiki are available.
The mod is practically compatible with other mods, according to its author, but the Modrinth page gives no list of tested companions, so check a server's other mods before relying on it.
Key features
Mob variations
Existing mobs gain variant forms, so several versions of the same creature can appear in one world.
Changed mob stats
Stats on some mobs are altered to make standard enemies less predictable in combat.
Split Undead Armies
Undead Armies are divided into different groups, so the same undead force does not appear in one uniform form.
Variant data stored in tags
Each variant is recorded under a type tag in the mob data, which keeps the variant choice saved with the entity.
Vanilla code base
The mod is built on existing Minecraft code and adds no new code paths of its own, which keeps its changes close to the base game.
