What is GlymeraCats?

Hytale has complete cat and kitten models sitting unused in its base assets. GlymeraCats activates them as real pets: they follow you, defend you, meow at strangers, and fight for you with real damage. Every cat has a unique name and one of 10 coat colors.

How to Get a Cat

Kill mobs to collect Life Essence and craft Concentrated Life Essence at the Farmingbench (100:1 ratio).
Craft a Cat Spawner at the Alchemybench under "Alchemy_Potions_Misc":
- 1x Raw Fish
- 1x Ingredient Life Essence Concentrated
Place the block wherever you want your cat to appear.
A random Cat or Kitten spawns on the block with a random coat and a random name. You are the owner.
Manage them with /gcat (opens the UI page).

OP players can also spawn cats directly with /gcat spawn cat, /gcat spawn kitten, or /gcat spawnpick <type> <variant> to target a specific coat.

Color Variants

Cats (10 coats)

Brown, Chestnut, Tawny, Golden, LightBrown, Amber, Reddish, DarkBrown, Mahogany, Rusty

Kittens (10 coats)

Golden, Wheaten, Red, Tan, Sable, Fawn, Mahogany, Caramel, Tricolor, Chocolate

All coats are natural feline fur tones. The cats' natural white belly, paws, and inner-ear regions are preserved, and facial features like eyes, nose, and snout keep their original colors - only the fur gets recolored. Use /gcat preview (OP) to spawn all 20 variants in a circle for comparison.

Combat System

Your cats defend you and themselves:

Trigger	Behavior
You get hit	All active cats hiss and attack your attacker
Cat gets hit by a mob	That cat fights back
Cat is in range of target	Real melee damage per claw swipe (Cat 20, Kitten 15)
Cat HP drops below 20%	Hurt sound (once per minute per cat)

Cats meow during combat (every 3s) and meow once when a stranger enters their 8-block awareness radius.

Management UI

Type /gcat to open a visual page showing all your cats as cards. Each card shows name, type, coat, and status:

Green "ACTIVE" = spawned and following
Yellow "DISMISSED" = offline, ready to call
Red "RESPAWN in Xs" = on death cooldown

Each card has buttons:

Come - teleport this cat to you (active only)

Release - free the cat permanently

OPs see additional top bar buttons to spawn new cats directly.

Installation

Place GlymeraCats-1.0.0.jar in your server's mods/ folder.
Start (or restart) the server.
Done. No external folders needed - everything is embedded in the JAR.

Good to Know

Cats are despawned when you disconnect and respawned when you rejoin (with a 2s delay, up to maxCatsActive).
Cats do not attack other players - they only target hostile NPCs/mobs.
Block placement is the normal way for players to get cats. Direct spawn commands are OP-only.
Dismissed cats stay in your roster - use Call to bring them back any time (subject to maxCatsActive).
Uses Hytale's native Cat and Kitten base models with custom textures generated per variant. The texture generator preserves the original cats' natural white regions (belly, paws, inner ears) and facial features (eyes, nose, snout) while recoloring only the fur.
All cat data is stored as JSON files per player in the plugin data directory.
