Minecraft, but LIFE = SIZE

Mokey Mod: Minecraft, but LIFE = SIZE

📏 The more health you have, the bigger you get. The less health you have, the smaller you shrink. That simple — and completely chaotic in practice.


Picture this: a Creeper blows you up, you lose half your health, and you literally shrink on the spot. Your friend, stacked with bonus hearts, has turned into a giant walking over blocks like they're stairs. Even mobs change size with their health — a zombie on its last legs becomes a tiny, easy target, while a full-health Ender Dragon looks noticeably more menacing.


Health = Size is a mod for Minecraft 1.21.8 that turns health (HP) into a real-time visual variable for any creature — players, mobs, and even the Ender Dragon. Your health isn't just a number on a bar: it literally makes you bigger or smaller, changes your step height and your hitbox, all synced every single game tick.

🩶 How It Works

Health-based scaling (real-time, every tick)

• • Players: size is calculated as current health ÷ 20, clamped between 0.5x (low health) and 2.0x (high bonus health). At the vanilla default of 10 hearts (20 HP) you're at normal size (1.0x); push past 20 bonus hearts and you hit the max size of 2x.

• • Mobs in general: size is calculated as current health × 0.25, clamped between 0.2x and 5.0x — so a rare, high-health mob can get truly massive.

• • Ender Dragon: gets a special max-size cap of 3.0x (instead of 5.0x), with dedicated client-side mixins to properly scale the 3D model and body-part hitboxes during combat.

• • Step height scales right along with size — the bigger the creature, the higher it can climb over blocks without jumping.

• • Armor Stands, and dead or removed entities, are never resized.

• • Everything recalculates automatically every server tick: there's no noticeable delay between taking damage/healing and the creature changing size.

Heart of Life (permanent progression item)

• • A consumable item (right-click to eat, ~1.6s use time).

• • Each one consumed grants +2 permanent max-health hearts (+4 HP), with a heart sound effect and particles on use.

• • There's a total max-health cap of 200 HP (100 hearts) — once you hit the cap, the item can no longer be consumed and you get a warning message in chat.

• • Bonus hearts survive death (they're copied over on respawn), making this a permanent progression system even in hardcore worlds.

• • Stacks up to 16, Uncommon rarity, found in the Food & Drink creative tab.

Mob drops

• • Any mob (except players) killed by a player has a 10% chance to drop 1 Heart of Life.

• • Respects the doMobLoot game rule — if it's off, drops are disabled too.
