Java Mob Aspects

Bedrock mobs, Java behavior. A behavior-pack-only add-on that makes vanilla Bedrock mobs fight, move, and react the way they do on Java Edition. No resource pack, no new mobs, no client install.

What it does

Bedrock mob AI cuts a lot of corners compared to Java — and you feel it in every fight. This pack closes those gaps. A few examples:

• Skeletons circle-strafe and kite like Java instead of standing still machine-gunning arrows — and they stop shooting when you break line of sight
• Mobs use Java's melee reach — no more getting hit mid-air while lining up a jump crit, no more spiders biting you from 2+ blocks away
• Zombies have Java's attack cooldown and stagger after landing a hit — and hurting one alerts the horde
• Spiders pounce-chain at you while chasing, like the Java jump-scare you remember
• The Wither is the Java fight: 300 HP (not Bedrock's 600), regeneration, projectile immunity below half HP

…and a lot more across hostile, neutral, and passive mobs. The changelog below is the full, always-current list — every release adds more parity fixes.

How it works

JMA hooks into the @minecraft/server script API. It does not replace vanilla entities or override AI components — it layers behavior on top via tick handlers and damage-event subscribers. That means:

• Server-side only — friends don't need to install it to join your world
• No new entities — compatible with every entity add-on you have installed
• Lightweight — one optimized entity scan, built to stay cheap even around mob farms

Installation

1. Download JavaMobAspects.mcpack
2. Double-click to open with Minecraft Bedrock — it installs automatically
3. In your world settings, add Java Mob Aspects as a behavior pack
4. Enable Beta APIs in the Experimental Features panel (required for script-driven packs)

That's it. The pack name shows its version, so you can always check which build your world is running.

Compatibility

• Minecraft Bedrock 1.21.20+ recommended
• Works in singleplayer, LAN, and Realms
• Plays nicely with most other behavior packs that don't fight for the same hooks
