Mob Life

Mob Life is a Fabric mod that makes you play as the mob form you choose when you create a world. It changes more than the model: movement, hitbox, eye height, vision, food, equipment, crafting, sleep, and combat all adapt to the selected body.

What it does

• Lets you choose your starting form during world creation.
• Stores that choice with the world so it becomes part of the save.
• Adjusts the initial spawn point so the chosen form can begin in a valid place.
• Supports player, cow, sheep, chicken, cat, ocelot, wolf, pig, horse, donkey, mule, and rabbit forms.
• Changes size, eye height, movement feel, sounds, and visual tint to match the form.
• Changes inventory capacity and available equipment slots by form.
• Lets data packs adjust the behavior of each form.
• Reads global options from config/mob_life.json, with a Mod Menu screen when the mod is installed.

Why it is different

Mob Life is not just a visual morph mod. It is built around the idea that each form should play differently.

Many morph mods focus on appearance or on copying a few abilities. Mob Life goes further: form-specific movement, jumping, reach, mining, inventory size, equipment, food, sleep, vision, and combat are all part of the design.

The world-creation choice is also important. The form you pick becomes part of that world's identity, rather than a temporary disguise you switch into later. You can still change forms with /moblife morph, but the starting choice sets the tone for the world.

Playing the mod

• Pick a form when you create a new world.
• Play with the movement, vision, food, equipment, and crafting rules that match that form.
• Use /moblife morph to change forms later if you want to try another body.
• Use data packs or config/mob_life.json to tune the defaults.

Forms

The built-in starting forms are:

• Player
• Cow
• Sheep
• Chicken
• Cat
• Ocelot
• Wolf
• Pig
• Horse
• Donkey
• Mule
• Rabbit

Configuration

Per-form defaults live at data/mob_life/mob_life/morphs/<mob>.json. Data packs can override the same path to change movement, vision, food, combat, inventory, sleep, and traits for each form. Running /reload reapplies the active configuration.

Global settings live in config/mob_life.json. That file controls the handling of normal-player morphs, rendering, inventory limits, mining and reach changes, and awkwardness debug text.
